WO2018059487A1 - Radio resource measurement method, selection method, and device - Google Patents

Abstract

A radio resource measurement method, a selection method, and a device are disclosed in the present application. Upon acquiring a beam measurement result, a terminal sends to a network device first indication information for indicating deactivation or deletion of a beam. If a beam satisfies a first quality condition, a network device deactivates or deletes said beam in accordance with the indication of the first indication information. This prevents situations in which normal communication between the terminal and the network device is affected by beams that do not meet communication quality requirements. In addition, upon acquiring a beam measurement result, a terminal may also send to a network device second indication information for indicating activation or addition of a beam, so as to indicate that the network device may communicate with the terminal by activating or adding a beam having good communication quality. Communication quality between the terminal and the network device is thus improved.

Technical field

The embodiments of the present invention relate to the field of communications technologies, and in particular, to a radio resource measurement method, a selection method, and an apparatus.

Background technique

While mobile communication technology is moving toward high-speed, large-data traffic, etc., the spectrum demand for communication transmission is also increasing. As the high-band spectrum has a large amount of available bandwidth, it will become an important resource for meeting the large-capacity and large-bandwidth requirements of future communications, and will also become the 3G communication technology, the 3rd generation partnership project (3GPP) and advanced Long-term evolution (LTE-A) further evolved target spectrum. Among them, the high-band spectrum includes the centimeter wave frequency band and the millimeter wave frequency band; the centimeter wave frequency band generally refers to the spectrum in the range of 3 GHz to 30 GHz, and the millimeter wave frequency band generally refers to the spectrum in the range of 30 GHz to 300 GHz.

The high-band wave is used in cellular communication as high-frequency cellular communication, and the area covered by the high-frequency cellular communication beam signal is called a high-frequency cell. Since the high-frequency cell generally has a small coverage area and the beam signal is easily blocked, and in a high-frequency cellular environment, the switching rate and handover failure rate of the user equipment (UE) are much higher than the low-frequency cell, and the handover is higher. The failure rate will cause user communication interruption and delay, which will result in greatly reduced quality of service (QoS) and user experience of the service, making high-frequency cellular communication challenge the mobility management of the UE.

In the related art, in the UE mobility management process, radio resource management (RRM) measurement by the UE and reporting of the measurement result to the base station are important ways for the secondary base station to perform handover determination, for example, in the existing LTE technology. The RRM measurement is based on a cell reference signal (CRS) or a channel state information reference signal (CSI-RS) of omnidirectional transmission. The UE measures the reference signal in the serving cell, the intra-frequency or the inter-frequency neighboring cell, and performs layer 3 smoothing filtering and averaging on the measurement result in a certain period of time, and reports the measurement result to the base station, so that the base station determines whether the base station determines whether Need to switch and select the target cell. However, in the process of high-frequency cellular communication, in order to compensate for the path loss of the high-band wave, it is necessary to adopt techniques such as beamforming to improve the communication coverage quality of the high-frequency cellular communication. In practice, when a reference signal for RRM measurement is transmitted in a beam manner, it cannot be measured by the RRM measurement method in the prior art. Moreover, since the high-frequency signal has the characteristics of low penetration force and fast attenuation of the signal quality of the obstructing object, once the high-frequency signal of communication between the UE and the base station is deteriorated, it is likely to affect the normal communication between the UE and the base station.

detailed description

Embodiments of the present application will be described below with reference to the accompanying drawings.

At present, cellular communication technologies such as Long Term Evolution (LTE) generally use a frequency band of about 2 GHz or lower, and the LTE-A small cell enhancement standardization project is studying and utilizing the 3.5 GHz band. LTE assisted access (LAA) technology is researching and utilizing unlicensed spectrum in the 5 GHz band. The 802.11ad standard of the Institute of Electrical and Electronics Engineers (IEEE) uses the 60 GHz band for wireless local area networks (WLANs), which are typically used for short-range indoor communications around 10 meters. However, 6 GHz or higher bands have not yet been used in cellular communication technologies. The main challenge of high frequency band waves such as centimeter wave and millimeter wave for cellular communication is that there is a large free space attenuation in these bands, and in addition to the absorption, scattering and other factors of air, rain, fog, buildings or other objects, It will cause the high frequency band to attenuate very much during the propagation process.

Beamforming technology is considered to be a potential technology to solve the significant path loss problem in the high frequency band of millimeter wave. Massive MIMO or large scale MIMO systems are considered The potential direction of beamforming technology is achieved at high frequencies. FIG. 1 is a schematic diagram of beamforming. A base station transmits a beam to a different direction at different times to achieve full coverage of a sector or a cell. In the prior art, there are three main methods for beamforming. The first one is a beam switching method, which is generally implemented by analog or radio frequency (RF) circuits. The second type is an adaptive beam ( Adaptive beamforming) is generally implemented using digital circuits; the third is hybrid beamforming, which is a combination of the above two methods.

High-frequency communication requires coverage by beamforming techniques, so reference signals used for RRM measurements may be transmitted in beams. However, the RRM measurement in the existing LTE technology is based on an omnidirectional CRS or CSI-RS. Therefore, in high-frequency cellular communication, it is not possible to effectively measure the reference signal transmitted by the beam by the prior art.

In order to solve the above technical problem, when a base station transmits a beam reference signal to a terminal in a beam manner through a large-scale multiple-input multiple-output antenna, the present application provides a radio resource measurement method and apparatus for measuring a base station to send to a terminal. The beam reference signal, and the measured measurement result is sent to the base station in the form of a measurement report, and the base station can switch the cell and the downlink beam that communicate with the terminal according to the measurement report sent by the terminal, that is, the base station selects a suitable cell for the terminal and/or Select the appropriate downstream beam for communication. It should be noted that, in the embodiment provided by the present application, the base station sends a beam reference signal to the terminal in a beam form, and the beam reference signal includes, but is not limited to, a high frequency, a low frequency, and the like. However, embodiments of the present application are not limited thereto.

FIG. 2 is a schematic diagram of an application scenario provided by an embodiment of the present application, where the base station 100 includes a base station 100 and a terminal 200. The base station 100 is configured by using a radio access network (eNB), an Evolved Node B (eNB), and a terminal. The eNB is taken as an example. As shown in FIG. 2, the terminal 200 can establish a wireless communication connection with the cell covered by the base station 100, respectively. The base station 100 may be a LTE or a base station of a future communication system, such as a 5G base station, and includes various forms of base stations, such as a low frequency cell, a high frequency cell, and an unlicensed spectrum cell. In the embodiment, a high frequency cell is taken as an example for description. . Correspondingly, the terminal may be an evolved LTE terminal or a next generation terminal, such as a 5G terminal. In addition, the embodiment of the present application is applicable to a high-low frequency cell cooperation scenario and an independent high-frequency cell scenario, and a high-frequency cell may be covered by one or more Transmission Receiving Point (TRP) or high-frequency signals provided by the base station 100. In an embodiment provided by the present application, in conjunction with FIG. 2, the base station 100 transmits measurement configuration information of one or more high frequency frequencies to the terminal 200, so that the terminal 200 performs measurement according to the measurement configuration information, such as RRM. measuring.

The measurement configuration information includes one or a combination of the following: measurement frequency, measurement bandwidth, intra-frequency measurement configuration, inter-frequency measurement configuration, physical cell indentation (PCI), measurement time of the high-frequency cell Window information, Mobility Reference Signal (MRS) information, and measurement report configuration; the measurement report configuration may be a measurement report period or a threshold for triggering a measurement report.

When the intra-frequency measurement and/or the inter-frequency measurement are configured for the terminal, the difference between different beams, different cells, and different frequency points may be disregarded, and a unified RRM measurement time window is configured for the terminal, thereby reducing the terminal detection beam and the MRS. The complexity also helps the terminal to save power; it is also possible to configure the terminal with MRS at different sub-band positions on the carrier. As shown in FIG. 3, on a high frequency carrier, three different subbands are configured for the terminal to detect the MRS, reduce the overhead of the MRS, and improve the accuracy of the RRM measurement. Wherein, on the high frequency carrier of FIG. 3, three sub-bands are included: sub-band 1, sub-band 2 and sub-band 3.

The base station 100 transmits a beam reference signal for RRM measurement to the terminal 200 in a beam manner. For example, the base station 100 transmits a beam reference signal to the terminal through a massively multiple input multiple output antenna. The MRS sequences of the beam reference signals of different beams are the same, and the MRS sequences of the beam reference signals of different beams may also be different.

The terminal 200 receives the measurement configuration information and the beam reference signal sent by the base station 100, and the terminal 200 measures the beam reference signal according to the measurement configuration information, such as RRM measurement. The base station 100 can transmit multiple beam reference signals to the terminal 200. The terminal 200 can acquire one beam reference signal at the same time, and can also acquire multiple beam reference signals at the same time; and the terminal 200 acquires multiple different or identical beam reference signals at different times, that is, the terminal 200 acquires the same cell. The beam reference signal or the beam reference signal under different cells.

After the terminal obtains the beam reference signal, the beam reference signal in a certain period of time is measured, the measured value of the beam reference signal is obtained, and the measured value of the beam reference signal is filtered to obtain a measurement result; the measurement result may be It is a cell measurement result, and can also be a beam measurement result, or a cell measurement result and a beam measurement result. Optionally, the measurement result may be selected according to the type of measurement result sent by the base station. The measurement result type indication sent by the base station may be used to instruct the terminal to report the cell measurement result, or instruct the terminal to report the beam measurement result, or instruct the terminal to report the cell measurement result and the beam measurement result. For example, the measurement result type indicates that the terminal sends the cell measurement result, and the terminal needs to obtain the cell measurement result; the measurement result type indicates that the terminal sends the beam measurement result, and the terminal needs to obtain the beam measurement result;

The terminal 200 measures the beam reference signals in the same cell or different cells acquired by the terminal 200 according to the measurement configuration information sent by the base station 100, and obtains measurement values corresponding to the plurality of different beam reference signals respectively. The terminal obtains the measurement result by filtering the measurement values obtained in the preset time period. The measurement can be small The area measurement result can also be a beam measurement result, or a cell measurement result and a beam measurement result. The terminal 200 can transmit these measurements to the base station 100 in the form of a measurement report, so that the base station 100 selects a suitable cell or downlink beam to communicate with the terminal 200 according to the measurement report. Optionally, the measurement configuration information sent by the base station 100 includes measurement result type indication information, and is used to instruct the terminal 200 to send a cell measurement result, or a beam measurement result, or a cell measurement result and a beam measurement result to the base station 100;

After the terminal 200 measures the acquired beam reference signal according to the measurement configuration information sent by the base station, and obtains the measured value of the beam reference signal, the measurement value needs to be filtered to obtain the measurement result. Since the terminal is likely to move with the user's movement during the communication with the base station, the terminal 200 may acquire a beam reference signal at a certain time during the communication with the base station, or may be at a certain moment. Obtaining a plurality of beam reference signals (for example, a multipath signal of a received beam reference signal caused by reflection or the like in a serving cell or a beam reference signal of a neighboring cell); and the terminal 200 may acquire in a certain period of time. The beam reference signals of the same cell may also acquire beam reference signals of different cells.

Therefore, for the different situations encountered by the terminal 200, the measured values of the beam reference signal may be separately filtered by:

1) When the terminal acquires one beam reference signal at the same time, and the terminal acquires multiple beam reference signals at different times, the terminal performs corresponding measurement values of the plurality of beam reference signals acquired in the first set time range. During the filtering process, the terminal acquires the measured values corresponding to the multiple beam reference signals in the preset time range, and processes the measured values according to the first preset manner to obtain the measurement results of the multiple beam reference signals.

The first preset mode may be: averaging the measurement values corresponding to the multiple beam reference signals acquired in the preset time range, that is, averaging the measurement values corresponding to the multiple beam reference signals respectively, to obtain multiple beam references. The average measured value of the signal is used as the first measurement result of the plurality of beam reference signals, and the first measurement result is taken as the cell measurement result.

2) When the terminal acquires one beam reference signal at the same time, and the terminal acquires multiple different beam reference signals at different times, the plurality of different beam reference signals acquired by the terminal in the second preset time range respectively correspond to During the filtering of the measured values, the terminal acquires the measured values corresponding to the multiple different beam reference signals in the second preset time range, and processes the measured values according to the second preset manner to obtain the multiple different The measurement result of the beam reference signal can be used as a cell measurement result.

Wherein, when the second preset mode is adopted, considering the difference between the plurality of different beam reference signals, for example, the same beam reference signal may be used as one type among the plurality of different beam reference signals, and thus The multiple different beam reference signals may be divided into multiple categories, and the measured values corresponding to the respective beam reference signals in each category are averaged to obtain an average measured value corresponding to the beam reference signal, so that multiple The average measurement value corresponding to the beam reference signals of the category is used as the second measurement result of the plurality of different beam reference signals, and the second measurement result can be used as the beam measurement result.

3) When the terminal acquires multiple beam reference signals at the same time, and the terminal acquires multiple different beam reference signals at different times, the plurality of different beam reference signals acquired by the terminal in the third preset time range are respectively During the filtering process of the corresponding measured value, the terminal acquires the measured values corresponding to the multiple different beam reference signals in the third preset time range, and processes the measured values according to the third preset manner to obtain the multiple The measurement result of the different beam reference signals can be used as the cell measurement result.

Since the terminal can acquire multiple beam reference signals at the same time in the third preset time range, the terminal acquires each The measured values of the plurality of beam reference signals acquired at one time are averaged, and the measured values of the plurality of beam reference signals at the same time are averaged to obtain an average measured value of the beam reference signals at the time, thereby obtaining multiple beam references. The average measured value of the signal at each moment.

The terminal acquires average measurement values corresponding to the multiple beam reference signals at different times in the third preset range, and processes the average measurement values according to the third preset manner to obtain a third measurement result, where the third measurement result can be used as Cell measurement results.

In the third preset mode, the average measured value corresponding to multiple beam reference signals at different times in the preset range may be averaged to obtain a measurement result.

4) When the terminal acquires multiple beam reference signals at the same time, and the terminal acquires multiple different beam reference signals at different times, corresponding to the plurality of different beam reference signals acquired by the terminal in the preset time range respectively During the filtering of the measured values, the terminal acquires the measured values corresponding to the multiple different beam reference signals in the fourth preset time range, and processes the measured values according to the fourth preset manner to obtain the multiple different beams. The measurement result of the reference signal can be used as a cell measurement result.

The terminal obtains multiple beam reference signals at the same time in the four preset time ranges, and the terminal acquires the measured values corresponding to the multiple beam reference signals acquired at each time, and obtains the maximum measured value of the beam reference signal at the same time. In turn, a maximum measured value corresponding to each of the plurality of beam reference signals at each time can be obtained.

The terminal acquires a maximum measurement value corresponding to each of the plurality of beam reference signals at each time in the fourth preset range, and processes the maximum measurement values according to a preset manner to obtain a measurement result.

The fourth preset manner may be: averaging the maximum measured values corresponding to the multiple beam reference signals at different times in the preset range to obtain a fourth measurement result, where the fourth measurement result may be used as a cell measurement result.

In addition, if the plurality of beam reference signals acquired by the terminal at the same time are the same beam reference signal, after acquiring the maximum measured value corresponding to each time, respectively, in the fifth preset mode, the beam reference signals at different times can be distinguished. And averaging the maximum measured values corresponding to the same beam reference signal at each moment, thereby obtaining average measured values corresponding to the beam reference signals of the respective types, and using the average measured value as the fifth of the plurality of different beam reference signals. The result is measured, and the fifth measurement result is taken as a beam measurement result.

Certainly, if a difference between a plurality of different beam reference signals is considered, that is, the plurality of beam reference signals are divided into a plurality of different beam reference signals, and the types of maximum measured values corresponding to the respective moments may be determined. The maximum measured value corresponding to the beam reference signal, and the measured value is used as a measurement result of a plurality of different beam reference signals, and the measurement result is used as a beam measurement result.

5) When the terminal acquires multiple beam reference signals at the same time, and the terminal acquires multiple beam reference signals at different times, the corresponding measurement of the plurality of beam reference signals acquired by the terminal in the fifth preset time range respectively During the filtering process, the terminal acquires the measured values corresponding to the multiple beam reference signals in the fifth preset time range, and processes the measured values according to the preset manner to obtain the measurement results of the multiple beam reference signals. The measurement result can be used as a cell measurement result.

The terminal obtains a plurality of beam reference signals at the same time in the fifth preset time range, and the terminal acquires the measured value of the beam reference signal acquired at each moment. If the terminal acquires multiple beam reference signals at a time, then The terminal averages the measured values corresponding to the multiple beam reference signals to obtain an average measured value at the same time; if the terminal acquires a beam reference signal at the same time, the measured value of the beam reference signal is taken as the moment The average measured value, so that the average measured value of the beam reference signal at each time can be obtained. Then, the sixth preset party The sixth measurement result of the plurality of beam reference signals in the fifth preset time range is obtained by averaging the average measured values corresponding to the respective time points, and the sixth measurement result is used as the cell measurement result.

6) When the terminal acquires multiple beam reference signals at the same time, and the terminal acquires multiple beam reference signals at different times, the terminal performs corresponding measurement values of the plurality of beam reference signals acquired in the preset time range. During the filtering process, the terminal acquires the measured values corresponding to the multiple beam reference signals in the sixth preset time range, and processes the measured values according to the seventh setting manner to obtain the measurement results of the multiple beam reference signals.

The terminal obtains a plurality of beam reference signals at the same time in the sixth preset time range, and the terminal acquires the measured value of the beam reference signal acquired at each moment. If the terminal acquires multiple beam reference signals at a time, then The terminal obtains the maximum measured value from the measured values corresponding to the multiple beam reference signals, and obtains the maximum measured value at the same time; if the terminal acquires a beam reference signal at the same time, the measured value of the beam reference signal is taken as The maximum measured value at this moment, so that the maximum measured value corresponding to the beam reference signals at each moment can be obtained. Then, the seventh preset mode may be to average the maximum measured values corresponding to the respective times, and obtain a seventh measurement result of the multiple beam reference signals in the sixth preset time range, and the seventh measurement result may be used as a cell. Measurement results.

In addition, if the difference between a plurality of different beam reference signals is considered, that is, the plurality of beam reference signals are divided into a plurality of different beam reference signals, and the eighth preset mode may be adopted, that is, the maximum measurement corresponding to each time point respectively. The maximum measured value corresponding to each type of beam reference signal is determined in the value, and the measured value is used as an eighth measurement result of the plurality of different beam reference signals, and the eighth measurement result is used as a beam measurement result.

The first preset mode to the eighth preset mode in the embodiment of the present application may be that the measured value of the beam reference signal is average filtered or maximized in the foregoing embodiment. The averaging can be calculated mathematically as needed, or it can be a weighting calculation; wherein the weighting calculates the averaging weight or coefficient, which can be configured or preset. See equation (1) and its corresponding embodiment in the above embodiment. In this embodiment of the present application, the measured values of different beam reference signals may be averaged or maximized.

It should be noted that, in the embodiment of the present application, multiple beam reference signals refer to two or more beam reference signals.

In the embodiment provided by the present application, as shown in FIG. 15, a schematic diagram when the terminal performs RRM measurement. In the embodiment of the present application, in the process of filtering the measured value of the obtained beam reference signal, the following method may be used for averaging, but the embodiment of the present application is not limited thereto.

The terminal performs layer 1 filtering (Layer 1 filtering) on one or more physical layer measurements according to a certain algorithm (for example, arithmetic average or weighted average), and delivers the filtered result to layer 3 (ie, RRC layer). ) Layer 3 filtering, Layer 3 filtering algorithm is shown in the following formula:

F _n =(1-α)·F _n-1 +α·M _n

among them:

Mn is the latest measured value received from the physical layer, and Fn is the updated measured value used to evaluate the measurement reporting criteria. Fn-1 is the previous measurement and F0=M1 is the first measurement received from the physical layer. a=1/2(k/4), where k is a filter coefficient, which is sent by the base station to the terminal through corresponding measurement configuration information.

The terminal performs the evaluation according to the measurement result and the measurement report criterion filtered by the layer 3, and determines whether the condition for reporting the measurement result is met. If yes, the terminal sends the RRM measurement report to the base station, and the measurement result after the layer 3 filtering is included.

When layer 3 filtering is used, the terminal determines the time range required for different filtering processes according to different measurement scenarios. For example, for the same-frequency measurement, the filter coefficient (filterCoefficient) k takes 200 ms; when the k value takes 0, it indicates that layer 3 filtering is not performed.

Through the foregoing embodiment provided by the present application, after the measurement result is obtained, if the measurement result satisfies the configuration condition, the measurement result is generated into a measurement report, and is sent to the base station through the terminal measurement report. The configuration condition may be set as needed, for example, setting a reception power threshold. In addition, when the terminal measures the beam reference signal sent by the base station, different sampling periods and sampling points can be adopted by different measurement models in the embodiment to meet different measurement requirements. The measurement results include cell measurements and/or beam measurements. The base station may select a serving cell for the terminal according to the cell measurement result, and select a communication beam signal for the terminal according to the beam measurement result.

The cell measurement result may include a serving cell measurement result and/or a neighbor cell measurement result. When the measurement result of the server cell does not satisfy the communication condition, if the neighboring cell satisfies the communication condition, the base station switches the cell communicating with the terminal to the neighboring cell.

In combination with the above embodiments, in the dual-connected (DC)-based high-low frequency cooperative architecture, the terminal 200 can be configured with different measurement reporting modes. As shown in FIG. 4, the terminal 200 can be directed to the primary base station (MeNB). The 300 transmits a measurement report including the measurement result of the cell, and the MeNB 300 determines, according to the measurement result of the cell, whether the operation of the secondary base station handover or the secondary base station change should be performed.

The terminal transmits a measurement report including the beam measurement result to the secondary base station (Secondary eNB, SeNB) 400, and the SeNB 400 selects an candidate beam suitable for communication with the terminal 200 according to the beam measurement result; or the terminal 200 transmits the cell measurement result to the SeNB 400. The measurement report is such that the SeNB 400 determines whether the inter-base station handover should be performed according to the cell measurement result.

When the base station acquires the measurement report sent by the terminal, the base station sends the measurement configuration information to the terminal again according to the measurement report. While receiving the measurement configuration information, the terminal further continues to acquire the beam reference signal sent by the base station. The terminal first determines a beam reference signal measurement set in the beam reference signal according to the measurement configuration information, and then determines a beam signal activation set in the beam reference signal measurement set, and activates the beam reference signal to focus on one or more measurement results. The beam reference signal is used as the target beam reference signal, and the terminal sends the measurement result corresponding to the target beam reference signal to the base station in the form of a measurement report, and is used by the base station to use the target beam reference signal as an alternative beam for communicating with the terminal.

In order to describe in detail how the terminal measures the beam reference according to the measurement configuration information sent by the base station, so that the base station uses the selected target beam reference signal as the candidate beam for communicating with the terminal according to the measurement report sent by the terminal, another embodiment provided by the present application. As shown in FIG. 5, the following steps may be included:

Step 1001: The base station sends measurement configuration information to the terminal.

The measurement configuration information may include one or a combination of the following information: one or more beam reference signals as information of a beam measurement set, a measurement set measurement period, an active set measurement period, beam configuration information, used to determine beam activation The first threshold of the set and the second threshold information for determining the best candidate beam (the values of the first threshold and the second threshold are not limited). Optionally, the measurement configuration information may further include measurement result type indication information, used to instruct the terminal 200 to send a cell measurement result, or a beam measurement result, or a cell measurement result and a beam measurement result to the base station 100;

Step 1002: The base station sends a beam reference signal to the terminal.

The beam measurement set may be all beams or partial beams in a specific cell in the beam reference signal, or all beams or partial beams in multiple cells, and the same cell may be covered by a plurality of different TRPs or beams transmitted by the same TRP. It is also configured to maintain different beam measurement sets for the serving cell and the neighboring cell respectively.

The beam configuration information may include one or a combination of the following information: beam identity or beam index of one or more beams, reference signal (RS), time-frequency resource information, and antenna port ( Port) information.

The measurement set measurement period is used by the terminal to measure each beam in the measurement set, and generate or update a beam activation set according to the measurement result; the active set measurement period is used by the terminal to measure each beam in the beam activation set to obtain communication with the terminal. The candidate beam; in general, the measurement set measurement period is greater than or equal to the active set measurement period. When the time set by the measurement set measurement period or the active set measurement period arrives, the terminal can perform measurement for a period of time, and after the end of the period of time, restart the cycle time. The measurement set measurement period or the active set measurement period may also be used only as the time for the terminal to maintain or update the beam measurement set or the beam activation set. During the time corresponding to the measurement set measurement period or the active set measurement period, the terminal performs for different beam sets. measuring.

Step 1003: The terminal measures each beam in the measurement set in the first measurement set period according to the measurement configuration information, to obtain a first measurement result.

The terminal detects and measures each beam in the beam measurement set according to the measurement set measurement period, and selects one or more beams as the beam activation set according to the measurement result and the first threshold; the terminal in the next measurement set measurement period or subsequent measurement The set measurement period may update the beam active set because the measurement results may change.

Step 1004: The terminal determines an activation set in the measurement set according to the first measurement result, and obtains a second measurement result by measuring each beam in the activation set.

The terminal detects and measures each beam in the beam activation set according to the activation set measurement period, and selects one or more beams according to the measurement result and the second threshold, for example, the terminal according to the threshold in the measurement configuration (or the preset number of reported beams) Requirement) selecting one or more best beams; the terminal reports information and measurement results of the selected one or more beams to the base station, and the base station uses the same as the candidate beam to communicate with the terminal, for example, for the SeNB to determine The terminal transmits a beam of a Physical Downlink Control Channel (PDCCH).

Step 1005: The terminal determines, according to the second measurement result, a target beam reference signal in the active set.

The best beam selected by the terminal during the next active set measurement period or subsequent active set measurement period may be different because the active set may be different and the best beam of the measurement in the active set may change.

Step 1006: The terminal sends the information corresponding to the target beam reference signal to the base station in the form of a measurement report.

Step 1007: The base station selects one of the best measurement results as the candidate beam for communicating with the terminal according to the measurement report sent by the terminal.

When the base station needs to update the beam measurement set, the base station sends new configuration information to the terminal, and performs step S1001 to configure a new beam measurement set and other parameter information for the terminal.

In the above steps, the beams in the beam measurement set and the beam activation set may not belong to the same cell, and may be the same frequency or different frequency.

It should be noted that, when obtaining the measurement result of the beam reference signal, the foregoing method may be used, and details are not described herein again.

The above steps may be used in a dual connectivity or multi-connection architecture, for example, a high frequency SeNB set includes multiple SeNBs (first SeNB and other SeNBs) or multiple TRPs, and a beam measurement set or beam active set includes multiple SeNBs or multiple TRPs. The beam information is sent by the terminal to the MeNB or the first SeNB for selecting the first SeNB or other SeNB or SeNB set or their candidate beam information.

The radio resource measurement method provided by the embodiment of the present application can be used in RRM measurement of a high frequency cell or the like, so that In the scenario where the high-frequency cell is deployed, the terminal selects a suitable high-frequency cell and/or a suitable downlink beam for communication, and further, can select a suitable beam for the terminal to communicate, thereby supporting the mobility of the terminal, and ensuring The continuity of communication reduces the probability of communication interruption.

In addition, the embodiment of the present application can measure L1/L3 layer 3 of the measurement model of the downlink beam-independent (ie, regardless of the characteristics of the downlink beam itself) and the downlink beam-specific measurement model, and can adopt different measurement requirements (such as period, sampling points). ), reducing terminal processing overhead and ensuring different measurement accuracy requirements.

Under the dual-connection architecture, the downlink beam-independent (ie, regardless of the characteristics of the downlink beam itself) measurement model makes the beam information of the SeNB hidden from the MeNB, simplifies the cell-level mobility management process, and reduces the signaling overhead of the measurement report.

The downlink beam-specific (ie, considering the characteristics of the downlink beam itself) measurement model enables the SeNB to better manage different beams, and always selects the best candidate beam for communication with the UE, improving communication reliability and communication. Transmission rate.

In the embodiment of the present application, the terminal automatically maintains the beam activation set to activate the beam measurement information in the beam activation set by the set measurement period, reduces the terminal measurement processing overhead, and reduces the signaling overhead required by the base station to frequently configure the beam activation set for the terminal. Similar to terminal-controlled beam-level mobility management, network processing is simplified and latency is reduced. The best one or more of the beam information is reported to the base station by the terminal, so that the base station always selects the most suitable downlink beam to communicate with the terminal.

In still another embodiment provided by the present application, a Radio Link Monitoring (RLM) method of a high frequency cell is also provided.

In LTE, the process of performing RLM by the terminal is as follows: The physical layer of the terminal determines whether to send an out-of-synchronization indication or a synchronization indication to the upper layer protocol layer by measuring the cell reference signal CRS measurement and/or the measurement of the reception condition of the physical downlink control channel PDCCH. When the terminal continuously receives the downlink out-of-synchronization indication (out of sync) sent by the physical layer is equal to the preset value, the timer is started; if the downlink synchronization indication of the preset number of times sent by the physical layer is continuously received during the running, (insync), the timer is stopped, indicating that the radio link has been restored; if the timer expires, the terminal considers that the radio link failure (RLF) will trigger the RRC connection reestablishment process. In addition, the radio link control (RLC) protocol data unit reaches the maximum number of retransmissions, and the random access procedure fails to reach the maximum number of retransmissions, and the radio link failure is determined to occur. Exemplarily, the timer can be T310.

Since the monitoring frequency of the RLM is very high (the time requirement for sample monitoring is relatively dense), if the terminal always detects all the beams in the cell, the terminal processing load is large and may affect normal communication behavior. In order to reduce the RLM cost of the terminal, the embodiment of the present application may include the following steps in the RLM of the high-frequency cell: the terminal uses the downlink beam-specific RRM measurement method in the foregoing embodiment to determine the best downlink beam; A good downlink beam performs radio link monitoring RLM; when the best downlink beam changes, the terminal performs the RLM process based on the new best downlink beam. Exemplarily, in the first stage, the terminal performs RLM based on the beam B1 in the beam reference signal, and in the second stage, the terminal performs RLM based on the beam B4 in the beam reference signal.

When the terminal performs RLM on the target beam reference signal within the preset time range, the terminal determines whether the target beam signal satisfies the condition of the RLF. If the terminal determines that the target beam reference signal satisfies the RLF condition, the terminal triggers the radio resource control connection re-establishment process. That is, the radio resource control link re-establishment request message is sent to the base station.

In addition, when the measurement result of the target beam reference signal is lower than the third preset threshold, the terminal selects the beam reference signal to activate the RLM of the beam in which the other beam reference signals of the target beam reference signal are located; the terminal may perform parallel for multiple beams. RLM.

Alternatively, the terminal performs RLM on all beams in the beam reference signal active set.

The terminal selects each beam reference signal according to the beam reference signal to activate each beam reference signal according to the measurement result from high to low, and selects each beam reference signal to perform RLM. When the beam reference signal measurement result is higher, the beam reference signal measurement result is lower than the third preset. At the threshold, the beam reference signal with a lower beam reference signal measurement result is selected for RLM.

When the terminal determines that both the target beam reference signal and the other beam reference signals except the target beam reference signal satisfy the condition of the RLF, the radio resource control connection re-establishment process is triggered.

In order to solve the related technical problem and elaborate the execution flow in the foregoing embodiment, in another embodiment provided by the present application, in combination with the foregoing embodiment, a radio resource measurement method is provided, which is applied in a terminal, as shown in FIG. 6. The method can include the following steps:

In step S110, the terminal acquires first measurement configuration information.

The terminal acquires first measurement configuration information sent by the base station, where the first measurement configuration information includes one or a combination of the following: a measurement frequency, a measurement bandwidth, an intra-frequency measurement configuration, an inter-frequency measurement configuration, and a physical cell of the high-frequency cell. The physical cell indentity (PCI), the measurement time window information, the Mobility Reference Signal (MRS) information, and the measurement report configuration; the measurement report configuration may be a measurement report period or a threshold for triggering the measurement report.

In step S120, the terminal acquires a beam reference signal transmitted by one or more base stations.

The beam reference signal is a base station transmitting a beam reference signal to the terminal through a massive multiple input multiple output antenna. The MRS sequences of the beam reference signals of different beams are the same, and the MRS sequences of the beam reference signals of different beams may also be different.

When the terminal is in the middle of a cell, the terminal may acquire the beam reference signal sent by the base station of the cell. During the process of the terminal moving, for example, the terminal moves from the central location of one cell to the process between the two cells, the terminal is very A beam reference signal sent by one or several base stations may be obtained, that is, the terminal acquires a beam reference signal sent by one or more cells.

In step S130, the terminal measures the beam reference signal according to the first measurement configuration information to obtain a measured value of the beam reference signal.

The terminal receives the measurement configuration information and the beam reference signal sent by the base station, and the terminal measures the beam reference signal according to the measurement configuration information, such as RRM measurement. The terminal performs measurement by using the received at least one beam reference signal. In the embodiment, the terminal receives the multi-beam reference signal sent by the base station as an example for description.

The terminal measures each beam reference signal in the received beam reference signal, obtains a measurement value of each measurement sample, and filters the measurement value of the beam reference signal according to the measurement value, and may also be based on the measurement result of the beam reference signal. Calculate the measurement results of the high frequency cell. The terminal generates a measurement report by using the measurement result, and sends the measurement report to the base station, so that the base station selects a suitable high frequency cell or a downlink beam to communicate with the terminal according to the measurement report.

For the specific measurement manner of the beam reference signal sent by the terminal to the base station, the foregoing related embodiments have been described in detail. For details, refer to the foregoing embodiment, and details are not described herein again.

In step S140, the terminal filters the measured value of the beam reference signal to obtain a measurement result.

The measurement results include cell measurements and/or beam measurements.

Because the beam reference signal is sent to the terminal by the base station, there may be instability factors, such as path loss, so that the measured value of the measured beam reference signal cannot represent all the beam reference information. The measurement result, therefore, it is necessary to filter the measured value of the beam reference signal in the preset time period to obtain the representative The measurement result of the beam reference signal acquired in the preset time period makes the measurement result more useful and useful.

The terminal performs layer 3 filtering on the new measurement value of the beam reference, that is, physical layer, MAC layer, and Radio Resource Control (RRC) layer filtering.

In addition, the terminal generates a measurement report by the measurement result, and sends the measurement report to the base station.

The measurement report may include a cell measurement report and a beam measurement report, and the base station includes a primary base station MeNB and an auxiliary station SeNB. The terminal sends the cell measurement report to the primary base station MeNB; the terminal sends the beam measurement report to the auxiliary station SeNB.

The beam reference signal is a beam reference signal in the same cell acquired by the terminal, or the beam reference signal is a beam reference signal of a different cell acquired by the terminal. Therefore, as a refinement of the method of FIG. 6, as shown in FIG. 7, in another embodiment provided by the present application, step S140 may further include the following steps:

In step S141, the terminal acquires measurement values corresponding to the plurality of beam reference signals measured in a predetermined time range.

In step S142, the terminal processes the measured values of the plurality of beam reference signals in a preset manner to obtain a measurement result.

The terminal can acquire one beam reference signal at the same time, and the terminal can also acquire multiple beam reference signals at the same time. The terminal may acquire the beam reference signal of the same cell in multiple preset times, and may also obtain the beam reference signal sent by different cells in the preset time period, and the terminal obtains the measured value after measuring the obtained beam reference signal respectively. The measurement process is performed to obtain the measurement result. The detailed process of filtering the measurement value by the terminal is already described in the above embodiment, and details are not described herein again.

In order to describe in detail how the terminal measures the beam reference according to the measurement configuration information sent by the base station, so that the base station uses the selected target beam reference signal as the candidate beam for communicating with the terminal according to the measurement report sent by the terminal, another embodiment provided by the present application. In the figure, as shown in FIG. 8, the following steps may be included:

In step S810, the terminal accesses the second measurement configuration information.

The measurement configuration information may include one or a combination of the following information: one or more beam reference signals as information of a beam measurement set, a measurement set measurement period, an active set measurement period, beam configuration information, used to determine beam activation A first threshold of the set and a second threshold information for determining the best candidate beam.

In step S820, the terminal determines a beam reference signal measurement set in the beam reference signal according to the second measurement configuration information.

Since the base station may send multiple beam reference signals to the terminal, the terminal may determine the beam measurement set of the plurality of beam reference signals to be measured according to the second measurement configuration information sent by the base station.

In step S830, the terminal measures the beam reference signal in the beam reference signal measurement set to determine a beam reference signal activation set.

Specifically, the second measurement configuration information includes a first preset threshold. Therefore, as a refinement of the method of FIG. 8, as shown in FIG. 9, in another embodiment provided by the present application, step 730 may further include the following steps. :

In step 831, the terminal measures the beam reference signal in the beam reference signal measurement set in the first preset period to obtain the measurement result in the first preset period.

In step 832, the terminal uses the beam reference signal whose measurement result in the first preset period is greater than the first preset threshold as the beam reference signal activation set.

The first preset period is equivalent to the measurement set measurement period in the above embodiment; and the second preset period is equivalent to the active set measurement period in the above embodiment.

The terminal measures the beam reference signal in the beam reference signal measurement set to obtain a measurement value of the beam reference signal, and selects a beam reference signal activation set from the beam reference signal measurement set according to the first threshold in the second measurement configuration information. For example, the beam reference signal is measured as a beam reference signal active set with a concentrated transmit power greater than a threshold.

The second configuration information, including the second preset threshold, is a refinement of the method of FIG. 9. In still another embodiment provided by the present application, the following steps may be further included:

In step 833, the terminal measures the beam reference signal of the beam reference signal activation set in the second preset period to obtain the measurement result in the second preset period.

In step 834, the terminal uses the beam reference signal whose measurement result in the second preset period is greater than the second preset threshold as the target beam reference signal.

In order to further select one or more best-precision beam reference signals from the beam reference signal activation set as the candidate beam, the terminal targets one or more beam reference signals with the largest active concentration measurement value according to the second preset threshold. The beam reference signal transmits the measurement result and the information corresponding to the target beam reference signal to the base station, so that the base station uses the target beam reference signal as an candidate beam for communicating with the terminal.

In the radio resource measurement method provided by the embodiment of the present application, the terminal receives the first measurement configuration information sent by the base station, and performs measurement according to the beam reference signal of the first measurement configuration information to obtain a measurement value of the beam reference signal, and the terminal pairs the beam reference. The measured value of the signal is filtered to obtain the measurement result. The measurement result may include a cell measurement result and a beam measurement result. The base station may determine, according to the measurement result, whether the serving cell or the beam needs to be handed over to communicate with the terminal.

Since the high-frequency signal has the characteristics of low penetration force and fast attenuation of the signal quality of the obstructing object, when the data is transmitted by the high-frequency communication between the terminal and the base station, once the high-frequency signal of communication between the terminal and the base station is deteriorated, It may affect the normal communication between the terminal and the base station. Therefore, in order to compensate for the path loss of the high-frequency signal to improve the reliability of the service transmission, the terminal generally configures multiple beams to simultaneously perform data transmission.

However, based on the inherent characteristics of low-frequency signal penetration and fast fading of the obstruction signal, for a terminal, although the beam configured for it is large and activated, the terminal communicates with the base station through the configured beam. If some of the beam signals suddenly fading, the terminal and the base station continue to maintain the active state of the beam, which will cause waste of network resources, and also cause a large increase in power consumption of the terminal.

Therefore, when the terminal communicates with the base station through multiple beams, in the case that the signal quality of the beam is suddenly decreased, in order to avoid the problem that the terminal and the base station continue to maintain the waste of the network resources caused by the beam, the embodiment of the present application further provides A wireless resource selection method and apparatus are provided.

In the embodiments provided herein, the beam is a spatial resource that communicates over high frequency signals. A base station can communicate with different terminals through the same beam, and one terminal can communicate with the base station through one or more beams. The solution provided in the embodiment of the present application is also applicable to other space resources, such as a port.

In a first design manner provided by an embodiment of the present application, the terminal may deactivate or delete a beam that does not meet the communication quality.

In this embodiment, the terminal can acquire the measurement result of the beam. The terminal can acquire measurement results of one or more beams. The one or more beams are beams in an active state for the terminal.

The state of the configured beam for the terminal can be divided into an active state and a deactivated state. The beam in the active state can also be called the activated beam, and the beam in the deactivated state can also be called the deactivated beam. The information of the deactivated beam can be retained on the terminal or the base station. For the terminal, the beam in the active state can be used for data transmission between the terminal and the base station, and the beam in the deactivated state is not used for data transmission between the terminal and the base station. By deactivating the operation, the activated beam can be turned into a deactivated beam; by activating the operation, the deactivated beam can be made into an active beam. Those skilled in the art will appreciate that the active and deactivated states of the beam are for the dimensions of the terminal. For example, a beam that is deactivated for a certain terminal may be an activated beam for other terminals. For another example, the base station deactivating a beam means that the base station sets the state of the beam to be deactivated for a certain terminal, and does not affect the state of the beam for other terminals.

A beam that is not configured for the terminal means that there is no information about the beam on the terminal.

There are many ways in which a terminal can obtain measurement results. For example, the terminal may perform measurement on the beam to obtain the measurement result, or may obtain the measurement result of the one or more beams from other terminals, or may acquire the measurement result of the one or more beams from the base station, and the one obtained from the base station. The measurement results of the multiple beams may be measured by the base station or by other terminals. Optionally, the base station may indicate a beam that the terminal needs to measure. Optionally, the terminal can select the beam to be measured by itself. This measurement can be used to evaluate the communication quality of the beam. For example, the measurement of the beam signal quality can be used as part of the measurement or as part of the measurement; for example, the measurement of the beam path loss can be used as the measurement or as part of the measurement.

After obtaining the measurement result of one or more beams, the terminal may determine whether the measurement result of the one or more beams meets the first quality condition, that is, whether the beam meets the communication quality requirement. The first quality condition is a condition for judging whether the beam meets the communication quality requirement, and the beam satisfying the first quality condition can be considered as a beam that does not meet the communication quality requirement. For example, the first quality condition may be that the signal quality is lower than a certain threshold, or the signal quality may be lower than a certain threshold for a period of time, or the signal quality is lower than a certain threshold for a period of time. For example, the first quality condition may be that the beam path loss is higher than a certain threshold, or the beam path loss is higher than a certain threshold for a period of time, or the beam path loss is higher than a certain time in a certain period of time. The number of thresholds is greater than the preset number of times and so on. The content of the first quality condition can be formulated as needed, and the content of the application is not limited. The first quality condition may be sent by the base station to the terminal, or may be specified in the communication standard. The first quality condition may also be implicitly indicated. For example, if the standard specifies that the quality requirement is that the signal strength is greater than or equal to the threshold A, then it may be considered that the first quality condition is implicitly indicating that the signal strength is less than the threshold A.

After determining, by the terminal, one or more beams that do not meet the communication quality requirement, the terminal may send the first indication information to the base station, where the first indication information is used to indicate to deactivate or delete the one or more beams that do not meet the communication quality requirement. Optionally, the terminal may activate or delete the one or more beams that do not meet the communication quality requirements by itself. After deactivating or deleting the one or more beams that do not meet the communication quality requirements, the terminal does not communicate with the base station by using the one or more beams that do not meet the communication quality requirements.

At the terminal or base station, the bit can be used to indicate the state of the beam. Deactivating the beam can be achieved by modifying the value of the bit. Deleting a beam can be achieved by deleting the context of the beam, that is, deleting the information of the beam stored on the terminal or the base station.

After receiving the first indication information sent by the terminal, the base station may deactivate or delete the one or more non-conformities. The beam of communication quality requirements. In the process of communicating with the base station, the terminal deactivates or deletes one or more beams that do not meet the communication quality requirements, and can avoid the sudden fading of the beam when the terminal communicates with the base station, etc. The problem of wasted network resources caused by communication that does not meet the communication quality requirements can also avoid the problem that the power consumption caused by the terminal communication is still increased when the terminal communication is still low.

The terminal may send the first indication information to the base station in multiple ways.

As a first alternative manner, the terminal may send the first indication information by using the beam that does not meet the communication quality requirement. Optionally, the first indication information may be a deactivation indication information or a deletion indication information. After receiving the first indication information on the beam, the base station can know that the beam needs to be deactivated or deleted.

The first indication information can be implemented in a variety of ways. An optional manner is that the identifier information of the beam that does not meet the communication quality requirement is used as the first indication information or a part of the first indication information. After receiving the identification information of the beam on the beam, the base station may deactivate or delete the beam. In another optional manner, the quality information of the beam that does not meet the communication quality requirement is used as the first indication information or a part of the first indication information. For example, the CQI=0 (Channel Quality Indicator) may be sent to the base station, and the base station may deactivate or delete the beam after receiving the CQI=0 on the beam. Among them, it can be considered that CQI=0 indicates that the communication quality of the beam is poor. Another alternative is to deactivate or delete the indicator as part of the first indication information or the first indication information. The deactivation indication information or the deletion indication information may be represented by a bit.

As a second alternative, the terminal may send the first indication information through other beams other than the beam that does not meet the communication quality requirement. When the first indication information is sent on the other beam, the identification information of the beam that does not meet the communication quality requirement may be used as the first indication information or a part of the first indication information. Optionally, the quality information of the beam that does not meet the communication quality requirement may also be used as part of the first indication information. Optionally, the deactivation indication information or the deletion indication information may also be part of the first indication information.

As a third optional manner, the terminal may send the first indication information to the base station through the macro network or the low frequency network. Sending information through a macro network or a low frequency network can be understood as transmitting first indication information to a base station through a network such as NR (new radio) network (abbreviated as 5G network), LTE network, UMTS network, GSM, or the like. For the implementation manner of the first indication information, reference may be made to the foregoing second optional manner, which is not described herein. Specifically, the terminal may send the first indication information by using the MAC layer or the RRC layer to send the first indication information to the base station by using the macro network or the low frequency network.

After the terminal sends the first indication information to the base station, the base station may deactivate or delete the beam that does not meet the communication quality requirement, that is, the base station may stop communicating with the terminal through the beam. After the terminal sends the first indication information to the base station, the terminal may stop listening to the beam. Optionally, the terminal may stop listening to the beam after receiving the feedback information sent by the base station for the first indication information. The feedback information may carry the deactivated or deleted beam identification information, where the beam identification information includes an identifier of the beam, or an antenna port identifier including a beam, or at least one of identification information such as a beam reference signal.

In this way, when the base station is subjected to external interference or the like, the base station can continue to transmit data to the terminal through the beam without receiving the first indication information sent by the terminal, thereby avoiding the problem that the terminal loses data due to the terminal stopping listening to the beam prematurely.

Because the high-frequency signal has the characteristics of low penetration force and fast attenuation of the signal quality of the obstructing object, in the embodiment, once the signal of the terminal communicating with the base station is attenuated, the terminal may send the first indication information to the base station to indicate The base station is shown to deactivate or delete the beam that satisfies the first quality condition. Exemplarily, in the process of the terminal moving, if the terminal enters the occlusion area, some of the beams that the terminal communicates with the base station are blocked by the occlusion area, thereby affecting the signal quality, resulting in a problem that the beam signal is attenuated, etc., at this time, the terminal The base station is notified to deactivate or delete these beams to avoid affecting the communication quality between the terminal and the base station.

For convenience of description, in the embodiment of the present application, the network device is a base station as an example. For example, the base station may be a base station with a 4G or 5G communication function, but the embodiment of the present application is not limited thereto.

The scheme of the first design described above will be exemplified below with reference to FIG. As shown in Figure 16, the following steps are included:

Step 200: The base station sends beam configuration information to the terminal.

The beam configuration information is used to instruct the terminal to communicate with the base station through beam1 and beam2.

Step 201: The terminal separately measures signal strengths of beam1 and beam2.

The terminal measures the signal strengths of beam1 and beam2, respectively, to determine whether the communication quality requirements are met.

Step 202: The terminal determines whether the signal strengths of beam1 and beam2 are respectively less than a threshold.

If the signal strength of beam1 is less than the threshold and the signal strength of beam2 is not less than the threshold, the terminal can determine that the signal quality of beam1 is poor. If the terminal continues to communicate with the base station through beam1, it may affect the normal communication between the terminal and the base station.

Step 203: The terminal sends the indication information to the base station by using beam1 or beam2.

The indication information is used to indicate that the base station deletes or deactivates the beam1, and the indication information may be the deactivation indication information or the deletion indication information. In addition, the indication information may include identification information of beam1, or signal strength of beam1, or CQI=0.

The terminal may send the first indication information to the base station through the MAC layer or the RRC layer. The first indication information may include: deactivation indication information or deletion indication information. The deactivation indication information or the deletion indication information is used to instruct the base station to deactivate or delete the beam1. The first indication information may further include a CQI of beam1. For example, the CQI=0 is used by the terminal to indicate that the signal quality of the base station beam1 is not suitable for continuing data transmission, so that the base station deactivates or deletes the beam1. Optionally, the first indication information may further include an identifier of beam1, or an antenna port identifier of beam1, or at least one of identification information such as a beam1 reference signal. In this way, when receiving the first indication information sent by the terminal, the base station passes the deactivation indication information or the deletion indication information in the first indication information, or deactivates the indication information or deletes the indication information and the identification information of the beam1 included therein, and beams1 Deactivate or delete to avoid normal communication between the terminal and the base station when transmitting data through beam1 with poor signal quality.

Step 204: The base station deactivates or deletes beam1.

After receiving the first indication information sent by the terminal, the base station deactivates or deletes the beam1. In the process of communicating with the base station, the terminal deactivates or deletes the beam that does not meet the communication quality requirement, and can avoid the network resources caused by the communication when the beam is suddenly fading in the case where the beam communicates with the base station. The problem of waste can also avoid the problem of greatly increasing power consumption caused by the terminal still communicating through the beam with lower communication quality.

Step 205: The base station sends feedback information of the first indication information to the terminal.

The feedback information is used to instruct the terminal to stop listening to beam1. Since the base station stops communicating with the terminal through beam1, it avoids problems such as resource waste caused by the terminal always monitoring beam1. The feedback information may carry the beam1 identification information, and the beam1 identification information includes the identifier of the beam1, or the antenna port identifier of the beam1, or the beam1 reference. At least one of identification information such as a signal.

Step 206: The terminal stops listening to beam1.

After receiving the feedback information of the first indication information sent by the base station, the terminal may stop monitoring beam1.

After transmitting the first indication information to the base station, the base station may deactivate or delete the beam1 that does not meet the communication quality requirement, that is, the base station may stop communicating with the terminal through the beam1. After the terminal sends the first indication information to the base station, the monitoring may stop monitoring the beam1. In addition, the terminal may stop listening to the beam1 after receiving the feedback information sent by the base station for the first indication information. In this way, when the base station is subjected to external interference or the like, the base station, if it does not receive the first indication information sent by the terminal and continues to transmit data to the terminal through the beam1, can avoid the problem that the terminal loses data by causing the terminal to stop listening to the beam1 prematurely.

In a second design manner provided by an embodiment of the present application, during the terminal mobile process, the communication quality of the deactivated beam or the new beam may meet the communication quality requirements. In order to improve the communication quality between the terminal and the base station, the terminal can activate or increase the beam conforming to the communication quality in another embodiment provided by the present application.

In this design, the terminal can obtain the measurement result of the beam. The terminal can acquire measurement results of one or more beams. The one or more beams are deactivated beams or unconfigured beams for the terminal. For example, the measurement result may include a measurement result of the beam signal quality or a measurement result of the beam path loss.

A beam that is not configured for the terminal means that there is no information about the beam on the terminal.

The state of the beam can be referred to the first design method described above, and will not be described here.

How the terminal knows the beam that needs to obtain the measurement result can be in various ways: the terminal can be determined according to the configuration information sent by the base station configuration, and the terminal itself can also blindly check the beam. There are many ways for the terminal to obtain the measurement result. For details, refer to the related content in the first design mode, and no further details are provided here.

After obtaining the measurement result of the one or more beams, the terminal may determine whether the measurement result of each beam in the one or more beams satisfies the second quality condition, that is, whether the beam meets the communication quality requirement. The second quality condition is a condition for judging whether the beam meets the communication quality requirement, and the beam satisfying the second quality condition can be considered as a beam meeting the communication quality requirement. For example, the second quality condition may be that the signal quality is higher than a certain threshold, or the signal quality may be higher than a certain threshold for a period of time, or the signal quality is higher than a certain threshold for a period of time. The number of times and so on. For another example, the second quality condition may be that the beam path loss is below a certain threshold, or the beam path loss is below a certain threshold for a period of time, or the beam path loss is below a certain threshold for a period of time is greater than the pre-predetermined Set the number of times and so on. The content of the second quality condition can be formulated as needed, and the content of the application is not limited. The second quality condition may be sent by the base station to the terminal, or may be specified in the communication standard. The second quality condition may also be implicitly indicated. For example, if the standard specifies that the signal strength is less than or equal to the threshold A and does not meet the quality requirement, then the second quality condition may be implicitly indicated as the signal strength is greater than the threshold A.

After the terminal determines one or more beams that meet the communication quality requirements, the second indication information may be sent to the base station, where the second indication information is used to indicate that the one or more beams that meet the communication quality requirements are activated or added. Optionally, the terminal may send the second indication information to the base station by using a beam other than the target beam. Optionally, the terminal may send the second indication information to the network device (such as the base station) by using the macro base station or the low frequency network. For example, the terminal may send the second indication information to the base station through the MAC layer or the RRC layer.

Optionally, before the terminal sends the second indication information to the base station, the one or more beams that meet the communication quality requirement may be actively activated or added for possible data transmission.

The second quality condition may be sent by the base station to the terminal, or may be specified in the communication standard.

Optionally, determining whether the beam meets the communication quality requirement may also be implemented by determining the number of NACKs received on the beam. In other words, the first quality condition and the second quality condition may use the number of NACKs as a basis for judgment. For example, the first quality condition may be that the number of NACKs is higher than the first threshold, and the second quality condition may be that the number of NACKs is lower than the second threshold; the information identifying the one or more beams that meet the communication quality requirement may be used as the second indication information or Part of the second indication. The information identifying the one or more beam that meets the communication quality requirement may be an identifier of the one or more beams that meet the communication quality requirement, and the antenna port identifier corresponding to the one or more beam that meets the communication quality requirement, the one or more A plurality of reference signals corresponding to the beam that meet the communication quality requirements, and the like. Optionally, the second indication information may further include the activation indication information or the addition indication information, and the activation or addition indication information may be represented by a bit.

Optionally, after the terminal sends the second indication information to the base station, the one or more beams that meet the communication quality requirement may be monitored, so that the base station sends data to the terminal by using the one or more beam that meets the communication quality requirement. The data sent by the base station on the beam or the ones that meet the communication quality requirements can be obtained in time. Optionally, after receiving the feedback information sent by the base station for the second indication information, the terminal may start to monitor the one or more beams that meet the communication quality requirements. The feedback information may carry the activated or added beam identification information, where the beam identification information includes the identifier of the beam, or the antenna port identifier of the beam, or at least one of the identification information such as the beam reference signal. For example, the second indication information indicates that the beam3 and the beam4 are activated or added, and the feedback information of the base station indicates that the beam4 can be activated, and the terminal can monitor the data communication on the beam4 after receiving the feedback information.

After receiving the second indication information sent by the terminal, the base station may activate or add the one or more beams that meet the communication quality requirement according to the second indication information, or the base station may activate or add the one according to the second indication information. Or a part of the beam in the beam that meets the communication quality requirements. . The base station can communicate with the terminal according to one or more beams that meet the communication quality requirements that are activated or added.

Optionally, the second indication information that is sent by the terminal to the base station may further include channel state information (CSI) of the one or more beams that meet the communication quality requirement, or other information that can reflect the communication quality. After receiving the above information, the base station can select a better beam for activation or addition.

It should be noted that the scheme in which the terminal sends the second indication information to the base station may be combined with the scheme in which the terminal sends the first indication information to the base station. .

The first indication information or the second indication information is sent in multiple manners, for example, by using MAC layer signaling or RRC layer signaling, and then sent by, for example, beam control or beam management signaling.

As a variant of the solution involved in the above two design manners, the base station may acquire the measurement result of the beam, and send the first indication information or the second indication information to the terminal to instruct the terminal to deactivate/delete, or activate/increase the beam. For details, refer to the above two design methods, and replace the terminal in the above two design modes with the base station, and replace the base station with the terminal, which is not described herein.

Optionally, in a scenario where the uplink transmission link and the downlink transmission link between the terminal and the base station do not have symmetry (ie, no respiration), the terminal may implement the foregoing two design manners for the downlink beam, where the base station The solution of the above two design modes can be implemented for the uplink beam. .

For convenience of description, in the embodiment of the present application, the network device is a base station as an example. For example, the base station may be a base station with a 4G or 5G communication function, but the embodiment of the present application is not limited thereto.

The solution of the above second design mode will be exemplified below with reference to FIG. As shown in Figure 17, including the following step:

Step 300: The base station sends beam configuration information to the terminal.

The beam configuration information is used to instruct the terminal to determine whether beam3 and beam4 meet the communication quality requirements.

Step 301: The terminal measures the signal strengths of beam3 and beam4, respectively. The terminal can measure the signal strengths of beam3 and beam4 by measuring the signal strengths such as beam3 and beam4, which communicate with the base station and the base station, respectively. Where beam3 and beam4 may be beams that are not configured for use by the terminal by the base station or beams that are deactivated for the terminal.

Step 302: The terminal determines whether the signal strengths of the amounts beam3 and beam4 are greater than a threshold.

If the terminal determines that the signal strength of beam3 is greater than the threshold, and the signal strength of the beam is less than the threshold, the terminal can determine that the signal strength of beam3 can meet the requirements for communication between the terminal and the base station.

Step 303: The terminal sends the second indication information to the base station.

The second indication information is used to indicate that the base station activates beam3 or adds beam3 for communicating with the terminal.

The terminal may send the second indication information to the network device by using a beam other than beam3. The second indication information may include an identifier of beam3, or an antenna port identifier that transmits beam3, or a beam3 reference signal or the like that can be used to identify the beam. Optionally, the second indication information may further include activation indication information or addition indication information. In this way, when receiving the second indication information sent by the terminal, the base station activates beam3 or adds beam3 to the terminal to improve the communication quality between the terminal and the network device. Adding beam3 to the terminal means configuring beam3 for the terminal.

Step 304: The base station activates or adds beam3.

The base station receives the second indication information sent by the terminal, and may activate or add beam3, and then the base station and the terminal may communicate through the beam. Since the beam 3 has good communication quality, the communication efficiency between the terminal and the base station is effectively improved.

Step 305: The base station sends feedback information of the second indication information to the terminal.

After the base station activates or adds the beam 3, in order to enable the terminal to monitor the beam 3 in time, the base station sends the feedback information of the second indication information to the terminal. The feedback information may carry the beam3 identification information, and the beam3 identification information includes the identifier of the beam3, or the antenna port identifier of the beam3, or at least one of the identification information such as the beam3 reference signal.

Step 306: The terminal monitors beam3.

After receiving the feedback information of the indication information sent by the base station, the terminal can monitor beam3 to receive the data sent by the base station through beam3.

Optionally, the terminal may start listening to the beam 3 by itself after sending the indication information to the base station, without waiting for the base station to provide feedback information about the indication information.
