Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

The uplink coverage enhancement method for cell edge users disclosed in the present invention is for the uplink supplementary SUL mode of 5G NR (5G NewRadio) time division duplex (TDD), that is, the supplementary uplink mode. Embodiments of the method for enhancing uplink coverage for cell edge users according to the present invention will be described in detail below. As shown in Figure 1, it is a schematic flow diagram of the uplink coverage enhancement method for cell edge users provided by the embodiment of the present invention, and the specific implementation process includes the following steps:

Step 101: Detect the uplink channel sounding reference signal sent by the horizontal broadcast beam in the main serving cell to access the user equipment, and determine the access level value of the uplink channel sounding reference signal, and determine the access level value based on the access level value Check whether there are cell edge users in the horizontal broadcast beam.

In the embodiment of the present invention, before performing this step, that is, before detecting the uplink channel sounding reference signal of the horizontal broadcast beam accessing the user equipment, at least one horizontal broadcast beam needs to be pre-configured in the primary serving cell based on the new air interface. The horizontal broadcast beam includes a primary synchronization signal, a secondary synchronization signal and a physical broadcast channel. Wherein, the pre-configuration of at least one horizontal broadcast beam in the main serving cell based on the new air interface, the specific implementation process includes: determining the frequency band information of the new air interface in time division duplex mode; The primary serving cell is configured with at least one horizontal broadcast beam.

Specifically, the new radio interface (New Radio, NR) is a link between a user equipment (User Equipment, UE) and a 5G base station. The horizontal broadcast beam is an SSB (Synchronization Signal and PBCH Block) beam, which is composed of a primary synchronization signal (Primary Synchronization Signals, PSS for short), a secondary synchronization signal (Secondary Synchronization Signals, SSS for short), and a PBCH block (physical broadcast channel). The uplink channel sounding reference signal is an SRS (Sounding Reference Signal) signal.

Further, in the specific implementation process, based on pre-configuring at least one horizontal broadcast beam in the main serving cell based on the new air interface, when sending one of the horizontal broadcast beams, the time domain position of the horizontal broadcast beam is controlled. Transmission of horizontal broadcast beams. When at least two horizontal broadcast beams are sent, a horizontal broadcast beam in one direction is sent in the primary serving cell at each moment, so as to complete coverage of the entire primary serving cell. The directions of the horizontal broadcast beams sent at different times are different. As shown in FIG. 2 , the horizontal broadcast beams of different directions are sent sequentially from top to bottom at each time to complete the coverage of the entire main serving cell.

In the specific implementation process, firstly, as many horizontal broadcast beams as possible are configured in the main serving cell (ie, NR TDD cell) according to the frequency band information. In the NR TDD cell, the physical broadcast channel PBCH and the synchronization signal SS share an SSB (Synchronization Signal and PBCH Block) beam. The SSB beam is a cell-level beam. The gNodeB periodically sends broadcast synchronization messages and system messages on the SSB beam; NR TDD cells use For one SSB beam, the time-domain position of the SSB beam can be controlled. When the time-domain position of the SSB beam in different cells is different, the SINR of the SSB beam of the NR TDD cell can be improved; when the NR TDD cell uses multiple SSB beams, usually each time Send beams in one direction, and send SSB beams in different directions at different times to complete the coverage of the entire cell, as shown in Figure 2. Correspondingly, the user equipment will receive the signal of each SSB beam, and complete synchronization and system message demodulation on the SSB beam with the best signal quality. Among them, configure as many horizontal broadcast beams as possible in the main serving cell according to the frequency band information. Specifically, according to the 3GPP TS 38.213 protocol, the maximum number of beams of SSB beams in an NR TDD cell is: NR TDD frequency band is 1.88GHz–7.125GHz, then The maximum number of SSB beams can be 8, and the NR TDD frequency band is lower than 1.88GHZ, then the maximum number of SSB beams can be 4.

In this step, the specific implementation process of determining whether there are cell edge users in the horizontal broadcast beam based on the access level value includes: comparing the access level value with a preset first threshold value Yes, when the access level value is lower than the first threshold value, determine the corresponding count value; if the count value exceeds the preset second threshold value, determine the horizontal broadcast beam There is the cell edge user; if the count value does not exceed the preset second threshold value, it is determined that the cell edge user does not exist in the horizontal broadcast beam; wherein the access level value is Refers to the received power level value of the sounding reference signal for the horizontal broadcast beam to access the uplink channel, that is, the RSRP (Reference Signal Received Power) level value.

In the embodiment of the present invention, the user's SRS message and access level value are detected at each SSB beam to determine the location of the cell edge user. Specifically, the user equipment sends SRS within the activated BWP (Bandwidth Part) bandwidth, and the gNodeB receives and processes the SRS of the user equipment to obtain the corresponding SINR (Signal to Interference plus NoiseRatio), RSRP (Reference Signal Received Power), PMI (Precoding Matrix Indication), etc., so as to determine the location of the cell edge user based on the SRS message and the access level value of each SSB beam detection user. Among them, the SRS message and access level value of the user are detected based on each SSB beam, specifically including: the RSRP level of the SSB beam accessing the SRS is lower than a preset threshold T1, that is, it is counted, and it is set as:

Count _{SRS low level} ;

If T1=-105dBm, the RSRP level value of the SSB beam accessing the SRS is lower than T1, then count:

Count _{SRS low level} = 1;

Determine the cell edge users of NR TDD cells;

If the RSRP level value of the SSB beam accessing the SRS signal is lower than the T1 threshold and the count value exceeds the T2 threshold, set T2=100, then:

Count _{SRS low level} >100

Then it is determined that there are cell edge users in the SSB beam of the NR TDD cell.

Step 102: Determine the target horizontal broadcast beam of the cell edge user, and set the corresponding beam weight, antenna azimuth angle parameter and downtilt angle parameter, so that the supplementary uplink cell configured in the main serving cell The antenna main lobe maximizes the coverage of cell edge users.

In this step, it is determined that the target horizontal broadcast beam of the cell edge user exists, and the corresponding beam weight, the azimuth angle parameter and the downtilt angle parameter of the antenna are set, so that the supplementary uplink configured in the main serving cell The antenna main lobe of the cell maximizes the coverage of the cell edge users, and the specific implementation process includes: obtaining parameter information of a target horizontal broadcast beam of the cell edge user, and judging the location of the target horizontal broadcast beam according to the parameter information; Wherein, the parameter information includes the beam weight, the azimuth parameter and the downtilt parameter of the antenna; based on the antenna, the electrical performance index of the corresponding active array module is collected; based on the position of the target horizontal broadcast beam and the electrical performance index, adjust the target horizontal broadcast beam to set the corresponding beam weight, the azimuth angle parameter and the downtilt angle parameter of the antenna, so that the antenna main wave of the supplementary uplink cell configured in the main serving cell The flap maximizes the coverage of cell edge users. Wherein, the electrical performance index includes the horizontal half-power lobe width, the vertical half-power lobe width, and the adjustable range of the downtilt angle.

It should be noted that the present invention is aimed at the uplink supplementary SUL mode of 5G NR TDD, configure as many horizontal broadcast beams (SSB beams) as possible in the NR TDD primary serving cell, and detect the SRS message that each SSB beam accesses the user equipment , access level value, according to the access level value to determine the location of the user at the edge of the cell, set the targeted beam weight, antenna azimuth and downtilt angle for the SUL cell, so that the antenna main lobe of the SUL cell includes as much as possible There are many cell edge users, and finally achieve the goal of improving uplink coverage enhancement. The specific methods are described in detail below:

First, configure the SUL cell for the 5G NR TDD cell and associate it with the NR TDD cell. Specifically, a SUL cell is configured for a 5G NR TDD cell. When a user equipment accesses an NR TDD cell configured with a SUL cell, in order to ensure correct access of the user equipment on the SUL carrier, the gNodeB needs to send information related to the SUL carrier to to user equipment. Among them, the parameters that need to be configured in the SUL cell include the following: duplex mode: for the SUL cell, it needs to be set to cell_SUL; frequency band: the frequency band to which the SUL cell belongs, and the frequency bands supported by the SUL cell refer to Table 2; uplink frequency point: the SUL cell only needs to be configured Uplink frequency point; Uplink bandwidth: according to the SUL frequency band to which it belongs and the actual available uplink bandwidth, combined with the uplink frequency point, configure the uplink bandwidth of the SUL cell; subcarrier spacing: the subcarrier spacing of the SUL cell is configured as: 15KHz; root sequence logic index: Used to generate cell preamble. After completing the configuration of the SUL cell, associate the NR TDD cell with the SUL cell to establish a logical NR TDD cell supporting the SUL mode; when the idle state user equipment triggers random access, the downlink of the NR TDD carrier SSB beam measured by the user equipment When the RSRP voltage value is greater than the preset value, the user equipment judges to initiate random access on the NR TDD carrier; when the connected state user equipment randomly accesses, the gNodeB indicates the NR TDD carrier that the user equipment randomly accesses in the RRCReconfiguration message, and performs the following process:

The source gNodeB sends the A3 event measurement control in the system to the user equipment, instructing the user equipment to measure the NR neighboring cell signal; after receiving the measurement report reported by the user equipment, the source gNodeB forwards the RSRP of the target cell to the target gNodeB; the target gNodeB judges that the RSRP is greater than rsrp -ThresholdSSB-SUL initiates random access; the target gNodeB sends the random access information of the target cell NRTDD carrier to the source gNodeB, and the source gNodeB sends it to the user equipment through the RRCReconfiguration message; the user equipment initiates random access according to the target cell carrier information in the RRCReconfiguration message access.

Secondly, according to the SRS message and access level value of each SSB beam access user, the location of the cell edge user is determined.

Third, set targeted beam weights, antenna azimuths, and downtilt angles for the SUL cell, so that the antenna main lobe of the SUL cell includes as many cell edge users as possible, and ultimately achieve the goal of enhancing uplink coverage.

Specifically, obtain the SSB beam of the cell edge user in the NR TDD cell, and judge the position of the SSB beam according to the beam weight, azimuth and downtilt information of the NR TDD cell; the antenna of the NR TDD cell needs to collect the AAU (ActiveArray Units) Electrical indicators, including horizontal half-power lobe width, vertical half-power lobe width, and adjustable range of downtilt angle; AAU antenna horizontal half-power lobe width, vertical half-power lobe width, and adjustable range of antenna downtilt angle. Be specific. According to the SSB information of the cell edge users of the NR TDD cell obtained above, combined with the electrical performance index of the NR TDD cell antenna AAU, the antenna main lobe of the SUL cell includes as many SSBs as possible of the NR TDD cell edge users, that is Include as many cell edge users as possible.

Finally, through long-term accumulated data statistics, set the periodic SUL cell beam weight for a specific period; or according to the actual detection results, set the SUL cell beam weight for the scene that reaches the preset threshold. Specifically, if the SUL cell supports remote antenna adjustment, you can set the beam weight of the SUL cell for a specific period of time through data statistics; or according to the actual detection results, perform the beam weight of the SUL cell for the scene that reaches the preset threshold. Setting; if the SUL cell does not support remote antenna adjustment, you need to adjust the azimuth angle of the SUL antenna so that the main lobe of the antenna of the SUL cell includes as many SSB beams as possible for the edge users of the NR TDD cell, that is, includes as many as possible Cell edge users.
