Description

 Method and device for receiving capability report

Technical field

 The present invention relates to the field of mobile communications, and in particular, to a method and apparatus for receiving capability reporting. Background technique

 Mobile and broadband have become the development direction of modern communication technologies. 3GPP (3rd Generation Partnership Project) is committed to the evolution of 3G systems as the LTE (Long Term Evolution) system. The goal is to develop 3GPP wireless access. Technology is evolving toward high data rates, low latency, and optimized packet data applications. In future mobile communication systems, such as the next three generations (B3G: Beyond three Generation) or LTE-A (Long Term Evolution Advanced), the system will provide higher peak data rate and cell data throughput, so the system A wider transmission bandwidth is also required.

In LTE and previous wireless communication systems, there is only one carrier in one cell, and the maximum bandwidth in the LTE system is 20 MHz, as shown in FIG. In the LTE-A system, the peak rate of the system is greatly improved compared to LTE, and it is required to achieve downlink 1 Gbps and uplink 500 Mbps. If only one carrier with a maximum bandwidth of 20 MHz is used, the peak rate requirement cannot be achieved. Therefore, the LTE-A system needs to expand the bandwidth that the terminal can use, thereby introducing a CA (Carrier Aggregation) technology, which is to aggregate multiple consecutive or discontinuous carriers under the same eNB (base station). Serve the UE to provide the required rate. These aggregated carriers are also called CC (Component Carrier). Each cell can be a member carrier, and cells (member carriers) under different eNBs cannot be aggregated. In order to ensure that the LTE UE can work under each aggregated carrier, each carrier does not exceed 20 MHz at the maximum. The CA technology of LTE-A is shown in Figure 2. The LTE-A base station shown in Figure 2 has four carriers that can be aggregated. The base station can perform data transmission with the UE (User Equipment) on four carriers at the same time to improve system throughput. In order to support CA transmission, UEs of LTE-A require more receivers than UEs of LTE. In the existing LTE system, the radio capability and measurement capability of the UE are part of the UE capability, and the network is notified by the UE capability reporting process. The radio frequency capability of the UE includes which bands (bands) the UE supports, and whether duplex is supported on each band. The measurement capability of the UE includes whether the UE needs to measure the gap when measuring the other bands while the UE is working in a certain band. From these capabilities, the network side cannot judge that the UE has several receivers. Since the UE of LTE needs to support MIMO, the UE needs at least two receivers with the same radio frequency and measurement capability. Since the capabilities of the two receivers are the same, the UE does not indicate that there are several receivers in the LTE protocol, and there is no need to distinguish between network configurations.

 For UEs with multiple receivers, there are several cases when performing other non-operating frequency measurements:

 Case 1: The UE directly moves the RF device of the current working receiver, aligns its center frequency with the frequency to be tested, and performs measurement. After the measurement is completed, the RF device is moved back to the current working frequency, without affecting the UE. Data transmission and reception at the working frequency point;

 Case 2: The UE has multiple receivers, which enable an idle receiver to measure the required frequency points, and does not affect the receiver currently working by the UE and the data transmission and reception at the working frequency;

 Case 3: The UE needs to measure the gap to measure the frequency, which will affect the data transmission and reception of the UE at the working frequency. The data transmission and reception cannot be performed during the measurement gap.

 Since the UE capability currently only contains the information of the measurement gap, but does not include the number of receivers, the network cannot distinguish between case 1 and case 2, and thus cannot achieve the purpose of power saving the UE through reasonable measurement configuration. For example, the UE has two receivers, the currently working receiver 1 needs to measure a certain frequency point, and the closed receiver 2 does not need a gap to measure the frequency point, so the UE's measurement capability indicates that the UE measures the frequency. The point does not require a gap. At this time, the network side may consider that the UE measures the frequency point to belong to the case 1, so the gap is not configured. Therefore, the UE must turn on the receiver 2 to measure, and the power saving cannot be achieved.

Therefore, for a UE with multiple receivers, it is necessary to propose an effective receiver capability reporting mechanism to better understand the radio frequency capability and measurement capability of the network, thereby optimizing system performance. Summary of the invention

 The object of the present invention is to solve at least one of the above technical defects, and particularly to optimize the reporting of UE receiver capabilities, so that the network can better understand its radio frequency capability and measurement capability, thereby optimizing system performance.

The measurement is made to save power or not interrupt data transmission.

 Another embodiment of the present invention further provides a user equipment UE, including a sending module, a measuring module, and a receiving module.

 The sending module is configured to send information to the base station, where the information includes receiver capability information of the UE, and the receiving module is configured to receive measurement configuration information sent by the base station; The measurement configuration information is used to perform other non-operating frequency point measurements, and the UE is saved or not interrupted.

 The foregoing solution proposed by the present invention optimizes the radio frequency capability and the measurement capability of the receiver reported by the UE, and the UE side adds information about the capability of the UE receiver to the UE capability information, and notifies the network through the UE capability reporting process; After obtaining the UE capability, the UE is configured for measurement with reference to the receiver capability therein. In the above manner, when performing non-operating frequency measurement, the UE can turn off some receivers to save power of the UE; or enable a new receiver to perform non-operating frequency measurement without affecting the data of the UE at the working frequency. Send and receive. The above solution proposed by the present invention has little change to the existing system, does not affect the compatibility of the system, and is simple and efficient.

 In order to facilitate the understanding of the present invention, the above method or apparatus will be further described in conjunction with further embodiments.

 Embodiment 1 : RF capability expansion

 It is assumed that the UE currently has four receivers, wherein the radio frequency capabilities of the receivers 1 and 2 are the same (supporting the same band and duplex mode), and the radio frequency capabilities of the receivers 3 and 4 are the same as shown in the following table:

 In order to reflect the receiver capability of the UE, the type (or number) of receivers supporting a certain band is extended in the radio frequency capability:

The "receiver type (or number of receivers)" information in the above table is information that enables the network to understand the capabilities of the UE receiver. If the content is to be added, the current UE capability information, such as an RRC message, needs to be extended. The extension may be to add an IE (information unit) under each supported band, indicating that "the receiver supporting the band" Type (or number) " , for example, increase lbit. When the receiver type supporting a band is 1, the bit is set to "0". When the receiver type supporting a band is 2, the bit is set. For ". UE will pass the capability The UE capability reporting process notifies the network, and after obtaining the information, the base station can obtain the UE through the UE or the core network, and refer to the radio frequency capability to perform measurement configuration on the UE. Another solution is to add an identifier to each band to indicate whether the receiver supporting the band is of one type (one) or multiple types (multiple).

 The following describes how the base station uses the information to perform measurement configuration on the UE, thereby achieving the purpose of saving the UE or not interrupting data transmission. Assuming that the UE is currently working on band3, using receivers 1 and 2, both receivers need to use the measurement gap to measure the frequency of band4, and the information to measure the gap is used in the measurement capability of the UE (the existing measurement can be used) Capability), while receivers 3 and 4 are currently off, not working. The base station expects the UE to measure the frequency in band 4, but wants to save power to the UE, does not want to turn on the receivers 3 and 4, but uses the currently operating receivers 1 and 2 to make inter-frequency measurements. At this time, the base station configures a measurement gap for the UE, and instructs the UE to measure the frequency point in the band 4. The UE combines the measurement of the gap information with the frequency information of the required measurement, and determines that the currently working receivers 1 and 2 and the measurement gap are used to perform the band4. When measuring the frequency, there will be data interruption, but power saving. If the base station does not configure the measurement gap for the UE, but instructs the UE to measure the frequency in the band4, the UE can only turn on the receivers 3 and 4 for measurement, which does not affect the current data transmission of the UE, but consumes power. Example 2: Measurement capability expansion

 The UE capability is the same as that of Embodiment 1. In order to reflect the receiver capability of the UE, it is extended in the measurement capability to measure the reason why other bands do not need a gap under a certain band (whether it is multiple receivers;):

The "reason for not needing a gap" message in the above table is to enable the network to understand the UE receiver. Information about force. If the content is to be added, the current UE capability information, such as an RRC message, needs to be extended. The extension may be to add an IE (information unit) under the measurement capability of each band to another band, indicating "No. The reason for the need for gap ", for example, increase lbit, if the gap is required, the bit does not appear. If the gap is not needed, and the reason is "single receiver, the center frequency point is adjustable", the bit is set to "0". If gap is not required and the reason is "multi-receiver", the bit is set to "1". The UE notifies the network to the network through the UE capability reporting process. After obtaining the information, the base station can perform measurement configuration on the UE by referring to the radio frequency capability of the UE or the core network. It is also possible to change the measurement capability to 2 bits, the coding method and the respective meanings are as follows:

 The following describes how the base station uses the information to perform measurement configuration on the UE, thereby achieving the purpose of saving the UE or not interrupting data transmission. The radio capability of the UE is the same as the prior art, and only indicates which bands the UE supports. It is assumed that the measurement capability of the UE is encoded according to the 2 bits in the above table. When the UE currently works in the band3, when the base station receives the measurement capability of the UE, it is known that the UE does not need a gap when working on the band3, because the "multi-receiver" is used. Rather than because of "single receiver, the center frequency is adjustable", for example, the 2bit code is "10", and the base station wants the UE to measure band4. The base station configures a measurement gap for the UE, and instructs the UE to measure the frequency point in the band 4. The UE combines the measurement of the gap information and the frequency information of the required measurement to determine that the currently working receivers 1 and 2 and the measurement gap are used to perform the band 4 uplink frequency point. The measurement, there will be data interruption, but save power. If the base station does not configure a measurement gap for the UE, but instructs the UE to measure the frequency point in the band4, the UE can only turn on the receivers 3 and 4 for measurement, which does not affect the current data transmission of the UE, but cannot save power. Example 3: Combination of RF capability extension and measurement capability extension

The UE capability is the same as that of Embodiment 1. In order to reflect the receiver capability of the UE, RF energy can be Force expansion and measurement capability expansion are combined. For example, if the radio frequency capability is extended by 1 bit, it indicates whether a band is a type (one) or a plurality of types (multiple) receivers, as described in Embodiment 1, and the measurement capability is extended by 1 bit, indicating that when the gap is not required, Because "single receiver, center frequency point adjustable" or "multiple receiver". After the base station obtains the UE capability, the UE can be combined with the UE to determine the receiver capability. The manner in which the base station acquires the UE capability is the same as that described in Embodiment 1.

 The following describes how the base station uses the information to perform measurement configuration on the UE, thereby achieving the purpose of saving the UE or not interrupting data transmission. Assuming that the UE is currently operating on band3, the base station expects it to measure the frequency in band4. The UE's radio frequency capability indicates that the UE has multiple types of receivers on both band3 and band4. The measurement capability indicates that band4 is measured on band3 because of "multi-receiver". The base station configures a measurement gap for the UE, and instructs the UE to measure the frequency point in the band 4. The UE combines the measurement of the gap information and the frequency information of the required measurement to determine that the currently working receivers 1 and 2 and the measurement gap are used to perform the band 4 uplink frequency point. The measurement, there will be data interruption, but save power. If the base station does not configure the measurement gap for the UE, but instructs the UE to measure the frequency point in the band4, the UE can only turn on the receivers 3 and 4 for measurement, and does not affect the current data transmission of the UE, but consumes power. Example 4: Adding Receiver Capabilities

 The UE capability is the same as that of Embodiment 1. In order to reflect the receiver capability of the UE, the "receiver capability" related parameters of the UE are directly added to the capability information of the UE, and the parameters that can be added are as follows:

The "receiver type (number)" information in the above table is information that enables the network to understand the capabilities of the UE receiver. Whether the radio and measurement capabilities of each (each) receiver are expressed in the form of a list or a numbered index are information that enables the network to understand the capabilities of the UE receiver. Under The two tables represent the form of the list and the numbered index:

 List form:

According to the above scheme, the base station can fully understand the receiver capability of the UE. The following describes how the base station uses the information to perform measurement configuration on the UE, thereby achieving the purpose of saving the UE or not interrupting data transmission. Assuming that the UE is currently operating on band3, the base station expects it to measure the frequency in band4. The UE reports the receiver capability according to the list mode. After the base station obtains the capability information, it knows that the UE has two types (four) of receivers, and when the receivers 1 and 2 work on the band3, the band4 is measured. Need a gap. The base station configures a measurement gap for the UE, and instructs the UE to measure the frequency point in the band 4. The UE combines the measurement of the gap information with the frequency information of the required measurement, and determines to use the currently working receivers 1 and 2 and the measurement gap to perform the band 4 uplink frequency point. The measurement, at this time there will be data interruption, but save power. If the base station does not configure a measurement gap for the UE, but instructs the UE to measure the frequency point in the band 4, the UE can only turn on the receivers 3 and 4 for measurement, and does not affect the current data transmission of the UE, but cannot save power.
