Description

Technical Field

[0001] The present application belongs to the field of communication technology, and specifically relates to an information indication method, device and equipment. Background Art

[0002] When a user equipment (UE) communicates with a network side device (eg, a base station, a test device), if the UE can select an uplink beam for data transmission based on a measurement result of a downlink beam, then the UE is considered to support the beam correspondence capability.

[0003] After accessing the network, a UE equipped with multiple antenna panels reports the UE's own supported beam correspondence capabilities to the network side equipment, and then the UE communicates with the network side equipment based on one or more antenna panels in accordance with the beam correspondence capabilities supported by the UE itself.

As long as the same technical effect is achieved, the base station is not limited to specific technical vocabulary. It should be noted that in the embodiment of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0050] To facilitate understanding of the technical solutions provided by the present application, the main technical concepts involved in the embodiments of the present application are briefly described below.

[0051] Multiple sending and receiving points or multiple antenna panels:

[0052] 3GPP has standardized the multi-TRP or multi-panel scenario, which can increase the reliability and throughput performance of data transmission. For example, the UE can receive the same data or different data from multiple TRPs, and the UE can also transmit data to multiple transmission reception points (TRPs).

[0053] Beam correspondence:

[0054] When communicating, the UE needs to scan or train the uplink beam to obtain the appropriate beam pair between the UE and the base station (BS), but this method will bring a large overhead. If the UE can select the uplink beam based on the downlink measurement results, then this process can omit the uplink beam scanning or training to obtain the appropriate beam pair between the UE and the BS, thereby reducing the response delay. This process is called beam correspondence capability.

[0055] Due to the influence of the error in the measurement of the Reference Signal Receiving Power (RSRP) and the amplitude and phase errors between the transmitted (Transport, Tx) signal and the received (Receive, Rx) signal, the beam mapping capability has higher requirements for UE implementation (for example, antenna calibration, etc.). Different UEs are distinguished by UE capability, which includes the following two cases:

[0056] 1) The UE does not support beam correspondence without UL-Beam Sweeping. In this case, the UE needs the assistance of uplink beam scanning to select the uplink beam.

[0057] 2) The UE supports beamCorrespondenceWithoutUL-BeamSweeping. In this case, the UE does not need uplink beam scanning and can directly select the appropriate uplink beam based on the measurement results.

[0058] After the UE accesses the network, the UE capability is reported according to the request of the network side device, that is, the beam corresponding capability of the UE is reported.

[0059] For the above two types of UE, the following test indicators need to be met:

[0060] For the first type of UE, in addition to meeting the minimum peak equivalent isotropic radiated power (min peak EIRP) and spherical coverage with the assistance of uplink scanning, additional tolerance testing is required. Tolerance refers to the CDF curve of the EIRP difference between the uplink beam automatically selected by the UE based on downlink measurement and the best beam among all transmit beams (Tx beams) being less than 3dB (28GHz band) / 3.2dB (39GHz band) at 85%-tile.

[0061] For the second type of UE, it is only necessary to verify whether the min peak EIRP and spherical coverage indicators can meet the requirements without uplink scanning assistance. If they do, it is considered that the UE also meets the tolerance, and there is no need to measure the tolerance indicator.

[0062] The performance of the UE beam correspondence depends on the following two points:

[0063] 1) UE hardware transceiver consistency, for example, the amplitude and phase consistency of the transceiver channels.

[0064] 2) The accuracy of UE measurement affects the selection of uplink beams. The measurement accuracy is related to the SNR (Signal Noise Ratio) of the reference signal.

[0065] In R15, both the Synchronization Signal Block (SSB) and the Channel State Information Reference Signal (CSI-RS) can be used as reference signals to be measured, while R16 introduces SSB only / CSI-RS only as beam-corresponding enhancements, and defines separate capability signaling for SSB only and CSI-RS only. SSB only and CSI-RS only mean that the reference signal to be measured is only SSB or CSI-RS:

[0066] –beamCorrespondenceSSB-based-r16,SSB only

[0067] –beamCorrespondenceCSI-RS-based-r16, CSI-RS only.

[0068] The traditional beam correspondence capability is based on an activated antenna panel of the UE, and the UE hardware's transceiver consistency and the UE measurement accuracy are both in a relatively stable state during the UE operation. However, in a scenario where the UE is equipped with multiple antenna panels and more than one antenna panel is activated at the same time to access multiple TRPs, the amplitude and phase consistency of different antenna panels are different due to different implementations of different antenna panels; and the distances between the UE and multiple TRPs are different, and the interference levels of different antenna panels are different, resulting in different SNRs of reference signals received by different panels. Therefore, different antenna panels have different beam correspondence capabilities. Therefore, in a scenario with multiple transmitting and receiving points or multiple antenna panels, the UE communicates based on multiple antenna panels. It is necessary to dynamically inform the current UE whether it can still support beam correspondence, so as to avoid link failure or serious degradation of communication quality due to inconsistent information between the UE and the network side equipment. In a scenario with multiple transmitting and receiving points or multiple antenna panels, different antenna panels have different beam correspondence capabilities, so it is necessary to report the beam capabilities of different antenna panels of the UE.

[0069] However, the existing method for reporting beam correspondence capability reports according to the beam correspondence capability supported by the UE itself, and does not distinguish between antenna panels. Therefore, it cannot guarantee that one or more antenna panels of the UE have the beam correspondence capability supported by the UE itself reported by the UE to the network-side equipment, and cannot guarantee the beam correspondence requirements. Therefore, this method is not suitable for beam correspondence capability reporting in scenarios with multiple sending and receiving points or multiple antenna panels. In addition, the beam correspondence capability reporting method that does not distinguish between antenna panels requires that the UE can only be equipped with antenna panels with consistent performance parameters, thereby limiting the implementation form of the UE. At the same time, the existing beam correspondence capability is only reported after the UE accesses the network and cannot be updated in real time. When the beam correspondence capability of the UE changes due to changes in hardware performance or measurement performance, the network-side equipment cannot obtain the information in time, causing the communication link to be unstable and the communication quality to deteriorate.

[0070] In response to the problems existing in the related art, the present application provides an information indication method, which indicates or determines the beam correspondence capabilities of different antenna panels of the UE through indication information. In this way, the first device (such as a base station or a test device) can determine the beam correspondence capabilities of the different antenna panels of the UE according to the indication information, and the UE and the first device can communicate according to the beam correspondence capabilities of the different antenna panels of the UE, thereby ensuring the beam correspondence requirements of each antenna panel of the UE, which is conducive to the stability of the communication link and communication quality. In an embodiment of the present application, the UE can not only send indication information to the first device after accessing the network, but also send indication information to the first device when the beam correspondence capability changes due to hardware performance changes or measurement performance changes, so that the network side device can promptly know the beam correspondence capabilities of different antenna panels of the UE, which is conducive to the stability of the communication link and communication quality. In addition, the beam correspondence capabilities of multiple antenna panels of the UE may be different. The embodiment of the present application proposes to report the beam correspondence capabilities of different antenna panels of the UE, so that the performance parameters of all antenna panels of the UE are not required to be consistent, thereby expanding the implementation form of the UE.

[0071] The information indication method, apparatus and device provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through some embodiments and their application scenarios.

[0072] First, see Figure 2 , Figure 2 A flowchart of a method for indicating information provided by an embodiment of the present application is shown. Figure 2 As shown, the method comprises the following steps:

[0073] Step S210: When the user equipment UE supports multi-antenna panel transmission, the UE determines the beam corresponding capability of the first antenna panel, where the first antenna panel is one of the multiple antenna panels of the UE.

[0074] Step S220: The UE sends indication information to the first device, where the indication information is used to indicate or determine the beam correspondence capability of the first antenna panel.

[0075] The beam correspondence capability of the first antenna panel is one of the first beam correspondence capability, the second beam correspondence capability and the third beam correspondence capability:

[0076] The first beam correspondence capability is used to indicate that beam correspondence is supported and no uplink beam scanning assistance is required;

[0077] The second beam correspondence capability is used to indicate that beam correspondence is supported and uplink beam scanning assistance is required;

[0078] The third beam correspondence capability is used to indicate that beam correspondence is not supported.

[0079] In the embodiment of the present application, the user equipment may be Figure 1 The terminal 11 in the example of the terminal 11 and can be found in the previous text, which will not be repeated here.

[0080] Among them, the first beam corresponding capability means: the appropriate uplink beam can be selected according to the downlink measurement results, the second beam corresponding capability means: the appropriate uplink beam needs to be selected with the help of the uplink beam scanning results, and the third beam corresponding capability means: the appropriate uplink beam needs to be found through other methods.

[0081] In a specific implementation, the UE communicates with the first device based on one or more antenna panels. The beam correspondence capabilities of different antenna panels may be different. In order to enable the first device to identify the beam correspondence capabilities of different antenna panels of the UE, the UE sends indication information to the first device after determining the beam correspondence capabilities of the antenna panel. The first device then distinguishes the beam correspondence capabilities of each antenna panel of the UE according to the indication information, so that the first device can identify the beam correspondence capabilities of the antenna panel. The UE and the first device communicate according to the beam correspondence capabilities of different antenna panels of the UE, thereby ensuring the beam correspondence requirements and avoiding the failure of the communication link or severe degradation of communication quality due to inconsistent information between the UE and the first device.

[0082] In a specific implementation, when the user equipment UE supports multi-antenna panel transmission, the UE determines the beam corresponding capability of the first antenna panel, including:

[0083] A-1: the UE determines the beam correspondence capability of the first antenna panel from the first beam correspondence capability, the second beam correspondence capability, and the third beam correspondence capability;

[0084] A-2: The UE determines the beam correspondence capability of the first antenna panel from the first beam correspondence capability and the second beam correspondence capability.

[0085] In the embodiment of the present application, the beam correspondence capability supported by the antenna panel includes two cases. For the case of A-1, the antenna panel supports two different beam correspondence capabilities, and for the case of A-2, the antenna panel supports three different beam correspondence capabilities. Since the embodiment of the present application reports the beam correspondence capability of the antenna panel of the UE, it is not required that the performance parameters (i.e., beam correspondence capability) of all antenna panels remain consistent. The UE can be equipped with antenna panels with different beam correspondence capabilities according to actual conditions, thereby expanding the implementation form of the UE.

[0086] In a specific implementation, after accessing the network, the UE sends indication information to the first device, so that the first device distinguishes the beam corresponding capabilities of different antenna panels of the UE according to the indication information, and the indication information includes the following two types:

[0087] B-1: first indication information, where the first indication information is used to indicate the initial beam corresponding capability of the first antenna panel;

[0088] B-2: third indication information, wherein the third indication information includes at least one of a limit value and a determination rule of a beam corresponding capability supported by each antenna panel of the UE.

[0089] For the case where the B-1 indication information is the first indication information, the first device determines the initial beam correspondence capabilities of different antenna panels of the UE according to the first indication information, and then the first device communicates based on the initial beam correspondence capabilities of different antenna panels of the UE. In one embodiment, the initial beam correspondence capabilities of different antenna panels are determined based on preset beam correspondence capabilities, and in subsequent communications, the preset beam correspondence capabilities of each antenna panel no longer change. In another embodiment, the initial beam correspondence capabilities of different antenna panels are determined based on preset beam correspondence capabilities, and in subsequent communications, the preset beam correspondence capabilities of each antenna panel can be dynamically updated (see the description of the second indication information below for details).

[0090] Compared with the related technology, the first indication information reports the beam correspondence capability of different antenna panels of the UE, which is a more fine-grained beam correspondence capability reporting method (i.e., antenna panel level reporting) rather than a coarse-grained terminal beam correspondence capability reporting (i.e., terminal level reporting). Therefore, based on the method provided by the implementation of the present application, the first device can well identify the beam correspondence capability of different antenna panels of the UE, and then the UE and the first device communicate according to the beam correspondence capability of different antenna panels of the UE, thereby ensuring the beam correspondence requirements and avoiding the UE and the network side equipment from communicating according to the beam correspondence capability supported by the UE itself, which is conducive to the stability of the communication link and communication quality.

[0091] In the case where the B-2 indication information is the third indication information, the UE does not directly report the beam correspondence capabilities of different antenna panels to the first device, but reports the beam correspondence capabilities, limits and determination rules supported by different antenna panels. Among them, the determination rules may be pre-agreed between the UE and the first device. In this case, the third indication information may not include the determination rules, but only the limits. The limits in the third indication information reported to the first device by different UEs may be the same or different. The first device can determine the beam correspondence capabilities of different antenna panels by itself according to the third indication information reported by the UE, and the specific determination method will be described later. Since the beam correspondence capabilities of different antenna panels of the UE are determined by the first device itself, the first device can well identify the beam correspondence capabilities of different antenna panels of the UE, and then the UE and the first device communicate according to the beam correspondence capabilities of different antenna panels of the UE, thereby ensuring the beam correspondence requirements and avoiding the UE and the network side equipment from communicating according to the beam correspondence capabilities supported by the UE itself, which is conducive to the stability of the communication link and communication quality.

[0092] In a specific implementation, the first indication information includes at least one of the following:

[0093] C-1: beam correspondence capabilities of different antenna panels of the UE;

[0094] C-2: The UE supports the capability of simultaneous transmission of multiple antenna panels and the capability of corresponding to a single carrier beam;

[0095] C-3: The UE supports the capability of multiple antenna panels to transmit simultaneously and the capability of corresponding to a single carrier beam in each frequency band;

[0096] C-4: multi-antenna panel beam correspondence capability of the UE, used to indicate that all antenna panels of the UE support the same beam correspondence capability in all frequency bands;

[0097] C-5: The multi-antenna panel beam correspondence capability of the UE in a frequency band, which is used to indicate that all antenna panels of the UE support the same beam correspondence capability in the frequency band.

[0098] In an embodiment of the present application, after the UE accesses the network, the beam correspondence capabilities of different antenna panels can be reported to the first device in a variety of ways. For example, the UE reports that all antenna panels support the same beam correspondence capabilities in all supported frequency bands, the beam correspondence capabilities supported by each antenna panel in different frequency bands, etc. Different first indication information is used to report the beam correspondence capabilities of different antenna panels. After receiving the first indication information, the first device interprets the first indication information to determine the beam correspondence capabilities of the antenna panels reported by the UE. Specifically, for C-1, the first device obtains the beam correspondence capabilities of different antenna panels based on the beam correspondence capabilities of the different antenna panels indicated by the UE; for C-2, the first device interprets that the beam correspondence capabilities supported by the different antenna panels of the UE in all frequency bands are the same as the beam correspondence capabilities of the single carrier. If the UE indicates that the single-carrier beam correspondence capability is the first beam correspondence capability, the first device interprets it as the beam correspondence capability supported by different antenna panels of the UE in all frequency bands as the first beam correspondence capability; if the UE indicates that the single-carrier beam correspondence capability is the second beam correspondence capability, the first device interprets it as the beam correspondence capability supported by different antenna panels of the UE in all frequency bands as the second beam correspondence capability; for C-3, the first device interprets it as the beam correspondence capability supported by different antenna panels of the UE in this frequency band is the same as the single-carrier beam correspondence capability of the frequency band. If the UE indicates that the single-carrier beam correspondence capability in a frequency band is the first beam correspondence capability, the first device interprets it as the beam correspondence capability supported by different antenna panels of the UE in this frequency band is the first beam correspondence capability; if the UE indicates that the single-carrier beam correspondence capability in a frequency band is the second beam correspondence capability, the first device interprets it as the beam correspondence capability supported by different antenna panels of the UE in this frequency band is the second beam correspondence capability; for C-4, the first device interprets it as all antenna panels of the UE support the same beam correspondence capability in all frequency bands. If the UE indicates that the beam correspondence capability under the multi-antenna panel is the first beam correspondence capability, the first device interprets it as all antenna panels of the UE supporting the first beam correspondence capability in all frequency bands; if the UE indicates that the beam correspondence capability under the multi-antenna panel is the second beam correspondence capability, the first device interprets it as all antenna panels of the UE supporting the second beam correspondence capability in all frequency bands; for C-5, the first device interprets it as all antenna panels of the UE supporting the same beam correspondence capability in the frequency band. If the UE indicates that the beam correspondence capability under the multi-antenna panel in a frequency band is the first beam correspondence capability, the first device interprets it as all antenna panels of the UE supporting the first beam correspondence capability in the frequency band; if the UE indicates that the beam correspondence capability under the multi-antenna panel in a frequency band is the second beam correspondence capability, the first device interprets it as all antenna panels of the UE supporting the second beam correspondence capability in the frequency band.

[0099] In a specific implementation manner, the indication information includes first indication information or third indication information, and the UE sending the indication information to the first device includes:

[0100] The UE sends first indication information or third indication information to the first device based on a request of the first device.

[0101] In a specific implementation, after the UE accesses the network, the first device sends a request to the UE to request the UE for the initial beam correspondence capabilities of different antenna panels. After receiving the request information, the UE sends first indication information to the first device to indicate the initial beam correspondence capabilities of different antenna panels of the UE, or sends third indication information to the first device so that the first device can determine the initial beam correspondence capabilities of different antenna panels of the UE according to the third indication information.

[0102] In a specific implementation manner, the UE sends indication information to the first device to dynamically indicate the current beam correspondence capabilities of different antenna panels of the UE, and the indication information includes:

[0103] B-3: second indication information, where the second indication information is used to indicate the current beam corresponding capability of the first antenna panel.

[0104] In the embodiment of the present application, during the communication between the UE and the first device, the beam correspondence capabilities of different antenna panels may change. Therefore, the UE indicates the current beam correspondence capabilities of different antenna panels of the UE to the first device by reporting the second indication information, thereby achieving real-time update of the beam correspondence capabilities of different antenna panels of the UE, thereby avoiding inconsistent information between the first device and the UE due to changes in the beam correspondence capabilities of the antenna panels, resulting in link failure or reduced communication quality.

[0105] In specific implementation, the UE reports the current beam correspondence capabilities of different antenna panels of the UE through the first indication information and the second indication information. Specifically, after the UE initially accesses the network, the UE indicates the initial beam correspondence capabilities of different antenna panels of the UE to the first device through the first indication information. In the subsequent communication process, the UE dynamically indicates the current beam correspondence capabilities of different antenna panels of the UE to the first device through the second indication information.

[0106] In a specific implementation manner, the second indication information includes: the beam correspondence capability of the first antenna panel in the current frequency band.

[0107] In the embodiment of the present application, multiple antenna panels of the UE can operate in multiple frequency bands, and the current frequency band refers to one or more frequency bands used by the UE to communicate with the first device. The UE reports the beam correspondence capabilities of different antenna panels in the current frequency band to the first device through the second indication information, so that the first device can identify the beam correspondence capabilities of different antenna panels of the UE in the current frequency band.

[0108] In a specific implementation manner, the indication information includes the second indication information, and the UE sending the indication information to the first device includes at least one of the following:

[0109] D-1: the UE actively sends the second indication signal to the first device;

[0110] D-2: the UE sends the second indication information to the first device according to the period configured by the first device;

[0111] D-3: The UE sends the second indication information to the first device based on the request of the first device.

[0112] For D-1, after accessing the network, the UE determines the beam correspondence capability of the antenna panel in real time. After the beam correspondence capability of the antenna panel changes, it generates second indication information based on the current beam correspondence capability of the antenna panel, and actively sends the second information to the first device to tell the first device the current beam correspondence capabilities of different antenna panels.

[0113] For D-2, after accessing the network, the UE determines the beam correspondence capability of the antenna panel in real time and generates the second indication information, and sends the second indication information to the first device according to the period configured by the first device to tell the first device the current beam correspondence capability of different antenna panels. For example, if the period configured by the first device is 30 seconds, the UE sends the second indication information to the first device every 30 seconds.

[0114] For D-3, after accessing the network, the UE receives a request message sent by the first device, and then the UE determines the current beam correspondence capabilities of different antenna panels based on the request message and generates second indication information, and sends the second indication information to the first device.

[0115] In a specific implementation, when the user equipment UE supports multi-antenna panel transmission, the UE determines the beam corresponding capability of the first antenna panel, including:

[0116] The UE obtains a measurement result of the first antenna panel;

[0117] The UE determines a current beam correspondence capability of the first antenna panel according to a measurement result of the first antenna panel.

[0118] In an embodiment of the present application, the UE obtains the measurement result of the first antenna panel, which means: 1) the UE measures the reference signal received by the first antenna panel to obtain the measurement result of the first antenna panel; 2) the UE measures the first antenna panel based on the sensing device to obtain the measurement result of the first antenna panel. The measurement result may be L1-SINR (Signal toInterference plus Noise Ratio). After obtaining the measurement result of the first antenna panel, the current beam correspondence capability of the first antenna panel of the UE is obtained based on the measurement result of the first antenna panel and the determination rule. In addition, after the UE obtains the current beam correspondence capability of the first antenna panel of the UE, a second indication information is sent to the first device, so that the first device identifies the current beam correspondence capability of the first antenna panel of the UE according to the second indication information.

[0119] In a specific implementation manner, the UE determines, according to the measurement result of the first antenna panel, a current beam corresponding capability of the first antenna panel, including at least one of the following:

[0120] E-1: when the measurement result of the first antenna panel is higher than the first limit value, determining that the beam corresponding capability of the first antenna panel is the first beam corresponding capability;

[0121] E-2: when the measurement result of the first antenna panel is higher than the second limit value but not higher than the first limit value, determining that the beam corresponding capability of the first antenna panel is the second beam corresponding capability;

[0122] E-3: When the measurement result of the first antenna panel is not higher than the second limit value, determine that the beam correspondence capability of the first antenna panel is the third beam correspondence capability.

[0123] In a specific implementation, the content of the determination rule is obtained according to the type of beam correspondence capability supported by the antenna panel. 1) When the beam correspondence capability includes the first beam correspondence capability and the second beam correspondence capability, the determination rule includes E-1 item and E-2 item; 2) When the beam correspondence capability includes the first beam correspondence capability, the second beam correspondence capability and the third beam correspondence capability, the determination rule includes E-1 item, E-2 item and E-3 item.

[0124] In an embodiment of the present application, the determination rule of the beam correspondence capability of different antenna panels of the UE can be used by the UE or the first device, and the UE or the first device determines the current beam correspondence capability of different antenna panels according to the current measurement result and limit of the UE. Among them, the current measurement result of the UE includes two types: 1) measuring the reference signal received by the antenna panel to obtain the current measurement result of the UE; 2) measuring the antenna panel based on the sensor device to obtain the current measurement result of the UE.

[0125] In a specific implementation manner, the first indication information, the second indication information or the third indication information further includes at least one of the following: a frequency band and an identifier of the first antenna panel.

[0126] In the embodiment of the present application, the multiple antenna panels of the UE can operate in multiple frequency bands. When the UE communicates with the first device, it is usually based on the communication of some antenna panels in one or several frequency bands. Therefore, the first device only needs to know the beam correspondence capability of some antenna panels in one or several frequency bands.

[0127] In a specific implementation, after the UE accesses the network, the first device sends a request to the UE to request the beam correspondence capability of the antenna panel with a specified identifier, or to request the beam correspondence capability of different antenna panels with specified identifiers in a specified frequency band. Then, the UE generates corresponding indication information according to the request sent by the first device, and the indication information includes the beam correspondence capability of one or more antenna panels with specified identifiers requested by the first device, or the beam correspondence capability of one or more different antenna panels with specified identifiers requested by the first device in a specified frequency band.

[0128] In a specific implementation, the first indication information, the second indication information or the third indication information is associated with beam information.

[0129] In specific implementation, in order to indicate the beam correspondence capability status of different antenna panels of the UE, the beam correspondence capability status is associated with the beam information, and the beam information is associated with the physical layer signaling indicating the corresponding antenna panel, for example, TCI state, SRS resource set, etc.

[0130] The information indication method proposed in the above embodiment is described through the following embodiments.

[0131] Embodiment 1

[0132] Embodiment 1 describes that after the UE accesses the network, the UE sends the first indication information based on the preset beam correspondence capability to indicate the initial beam correspondence capability of different antenna panels of the UE, and the initial beam correspondence capability of different antenna panels of the UE will not change subsequently. The specific steps are as follows:

[0133] Step 1: The UE sends indication information to the first device, where the indication information is used to indicate or determine the beam correspondence capability of the first antenna panel.

[0134] Step 2: The first device receives indication information sent by the user equipment UE, and determines the initial beam corresponding capability of the first antenna panel of the UE according to the first indication information.

[0135] In the embodiment of the present application, after the UE accesses the network, the first indication information is sent based on the request of the first device, so that the first device interprets the first indication information and determines the initial beam correspondence capabilities of different antenna panels of the UE. At this time, the initial beam correspondence capabilities of different antenna panels are determined according to the preset beam correspondence capabilities and will not change subsequently.

[0136] For example, the UE reports through the first indication information: the beam correspondence capabilities (e.g., beam Correspondence-sTxMP) and single-carrier beam correspondence capabilities (e.g., beam CorrespondenceWithoutUL-Beam Sweeping) of the different antenna panels of the UE. At this time, the first device determines that the beam correspondence capabilities supported by the different antenna panels of the UE in all frequency bands are the same as the single-carrier beam correspondence capabilities. If the single-carrier beam correspondence capability is the first beam correspondence capability, it is determined that the beam correspondence capabilities supported by the different antenna panels of the UE in all frequency bands are the first beam correspondence capabilities, that is, the antenna panels support beam correspondence and do not require uplink beam scanning assistance. For another example, if the UE reports through the first indication information: the beam correspondence capability of different antenna panels of the UE in each frequency band (e.g., beam Correspondence-sTxMP) and the single-carrier beam correspondence capability of each frequency band (e.g., beam Correspondence Without UL-Beam Sweeping), then the first device determines that the beam correspondence capability supported by the different antenna panels of the UE in this frequency band is the same as the single-carrier beam correspondence capability of the frequency band. If the single-carrier beam correspondence capability is the first beam correspondence capability, then it is determined that the beam correspondence capability supported by the different antenna panels of the UE in this frequency band is the first beam correspondence capability, and the beam correspondence capabilities of different antenna panels of the UE in different frequency bands may be different.

[0137] Embodiment 2

[0138] Embodiment 2 describes that after the UE accesses the network, the UE sends third indication information based on the preset beam correspondence capability, so that the first device determines the beam correspondence capability of different antenna panels of the UE according to the third indication information. The specific steps are as follows:

[0139] Step 1: The UE sends third indication information to the first device, where the third indication information includes at least one of a limit value and a determination rule of beam correspondence capabilities supported by different antenna panels of the UE.

[0140] Step 2: The first device obtains the measurement result of the first antenna panel, and determines the current beam corresponding capability of the first antenna panel according to the third indication information and the measurement result of the first antenna panel.

[0141] In an embodiment of the present application, after the UE accesses the network, a third indication information is sent based on the request of the first device, and the third indication information includes: the beam correspondence capability and limit supported by different antenna panels of the UE and the determination rules of the beam correspondence capability supported by different antenna panels of the UE.

[0142] Among them, the beam correspondence capabilities supported by different antenna panels of the UE can be: the beam correspondence capabilities supported by different antenna panels of the UE in each frequency band (such as beam Correspondence-sTxMP) and the single-carrier beam correspondence capabilities of each frequency band (such as beam Correspondence Without UL-Beam Sweeping). The measurement result of the first antenna panel obtained by the first device is the measurement result reported by the UE, and then the first device compares the measurement result with the first limit value and the second limit value in the determination rule to determine the beam correspondence capabilities of different antenna panels of the UE.

[0143] Embodiment 3

[0144] Embodiment 3 describes that after the UE accesses the network, the UE sends the first indication information and the second indication information based on the preset beam correspondence capability to indicate the current beam correspondence capability of the first antenna panel. The specific steps are as follows:

[0145] Step 1: The UE sends first indication information to a first device, and the first device determines an initial beam corresponding capability of the first antenna panel according to the first indication information.

[0146] Step 2: Send second indication information according to the request of the first device, where the second indication information is used to indicate the current beam corresponding capability of the first antenna panel.

[0147] In an embodiment of the present application, the UE sends a first indication message according to a preset beam correspondence capability to indicate the initial beam correspondence capability of the first antenna panel. At this time, the initial beam correspondence capability of the UE's antenna panel is the beam correspondence capability of the antenna panel used when the UE initially accesses the network. When switching to other antenna panels or communicating in other frequency bands, the first device does not know the beam correspondence capability of the switched antenna panel in the working frequency band (i.e., the current beam correspondence capability), so the first device requests the UE to report the current beam correspondence capability, and then the UE reports the beam correspondence capability of each antenna panel in the working frequency band.

[0148] Embodiment 4

[0149] Embodiment 4 describes that after the UE accesses the network, the UE determines the current beam corresponding capabilities of different antenna panels of the UE based on the measurement results, and actively reports the current beam corresponding capabilities of the first antenna panel. The specific steps are as follows:

[0150] Step 1: The UE sends first indication information to a first device, and the first device determines an initial beam corresponding capability of the first antenna panel according to the first indication information.

[0151] Step 2: The UE obtains the measurement result, and determines the current beam correspondence capability of the first antenna panel based on the measurement result of the first antenna panel.

[0152] Step 3: The UE sends second indication information to the first device, where the second indication information is used to indicate the current beam corresponding capability of the first antenna panel.

[0153] In an embodiment of the present application, after the UE initially accesses the network, the UE indicates the initial beam correspondence capability of the first antenna panel to the first device through the first indication information. In the subsequent communication process, the UE determines the beam correspondence capability of the antenna panel, and after the current beam correspondence capability of the antenna panel changes, the UE actively sends the second indication information to the first device to dynamically indicate the current beam correspondence capability of the first antenna panel. Then, the first device can identify the current beam correspondence capability of the first antenna panel of the UE, and realize the real-time update of the beam correspondence capability of the first antenna panel, thereby avoiding the information inconsistency between the first device and the UE due to the change of the beam correspondence capability of the antenna panel, resulting in link failure or reduced communication quality.

[0154] For example, taking the antenna panel 1 and the antenna panel 2 of the UE as an example, the first device determines that the initial states of the antenna panel 1 and the antenna panel 2 are both the first beam corresponding capability according to the first indication information reported by the UE; the UE performs reference information measurement (i.e., obtains the measurement result), if the measurement result of the antenna panel 1 is higher than the first limit value, and the measurement result of the antenna panel 2 (for example, L1-SINR) is higher than the second limit value and not higher than the first limit value, then the UE is triggered to report and send the second indication information (e.g., beamCorrespondence Indication), notifying the first device that the current beam corresponding capability of antenna panel 2 is changed to the second beam corresponding capability; the UE continues to perform reference information measurement, if the measurement results of antenna panel 1 and antenna panel 2 are both higher than the second limit and not higher than the first limit, then the UE is triggered to report and send the second indication information to notify the first device that the current beam corresponding capability of antenna panel 1 is changed to the second beam corresponding capability; the UE continues to perform reference information measurement, if the measurement results of antenna panel 1 and antenna panel 2 are both not higher than the second limit, then the UE is triggered to report and send the second indication information to notify the first device that the current beam corresponding capabilities of antenna panel 1 and antenna panel 2 are changed to the third beam corresponding capabilities.

[0155] For another example, taking the antenna panel 1 and antenna panel 2 of the UE as an example, the first device determines, based on the first indication information reported by the UE, that the initial states of the antenna panel 1 and the antenna panel 2 are both the second beam corresponding capabilities; the UE performs reference signal measurement, and if the measurement result of the antenna panel 1 is higher than the first limit value, and the measurement result of the antenna panel 2 is higher than the second limit value and not higher than the first limit value, then the UE is triggered to report and send the second indication information to notify the first device that the current beam corresponding capability of the antenna panel 1 is changed to the first beam corresponding capability; the UE continues to perform reference information measurement, and if the measurement results of the antenna panel 1 and the antenna panel 2 are both not higher than the second limit value, then the UE is triggered to report and send the second indication information to notify the first device that the current beam corresponding capabilities of the antenna panel 1 and the antenna panel 2 are both changed to the third beam corresponding capabilities.

[0156] Embodiment 5

[0157] Embodiment 5 describes that after the UE accesses the network, the UE determines the current beam corresponding capability of the first antenna panel based on the request information of the first device, and reports the current beam corresponding capability of the first antenna panel. The specific steps are as follows:

[0158] Step 1: The UE sends first indication information to a first device, and the first device determines an initial beam corresponding capability of the first antenna panel according to the first indication information.

[0159] Step 2: Receive request information from the first device.

[0160] Step 3: The UE obtains the measurement result of the first antenna panel, and determines the current beam correspondence capability of the first antenna panel according to the determination rule of the beam correspondence capability of each antenna panel of the UE.

[0161] Step 4: The UE sends second indication information to the first device, where the second indication information is used to indicate the current beam corresponding capability of the first antenna panel.

[0162] In an embodiment of the present application, the UE obtains measurement results based on the request of the first device, and determines the current beam correspondence capability of the first antenna panel in real time based on the measurement results, and reports the current beam correspondence capability of the first antenna panel so that the first device can better identify the current beam correspondence capabilities of different antenna panels of the UE.

[0163] For example, when the UE accesses the network, the first device determines that the initial beam correspondence capability of the first antenna panel is the first beam correspondence capability based on the first indication information, and then the first device requests the UE to report the current beam correspondence capability of the antenna panel. The UE performs reference signal measurement based on the request information, determines the current beam correspondence capabilities of different antenna panels based on the measurement results of different antenna panels, and generates a second indication information to notify the first device of the current beam correspondence capability of the first antenna panel. Specifically, if the measurement result is higher than the first limit value, the current beam correspondence capability of the antenna panel is determined to be the first beam correspondence capability. When the measurement result is higher than the second limit value but not higher than the first limit value, the current beam correspondence capability of the antenna panel is determined to be the second beam correspondence capability. When the measurement result is not higher than the second limit value, the current beam correspondence capability of the antenna panel is determined to be the third beam correspondence capability.

[0164] Embodiment 6

[0165] Embodiment 6 describes that after the UE accesses the network, the UE reports the current beam corresponding capability of the first antenna panel according to the configuration period of the first device. The specific steps are as follows:

[0166] Step 1: The UE sends first indication information to a first device, and the first device determines an initial beam corresponding capability of the first antenna panel according to the first indication information.

[0167] Step 2: The UE obtains the configuration period of the first device.

[0168] Step 3: The UE obtains the measurement result of the first antenna panel, and determines the current beam correspondence capability of the first antenna panel according to the determination rule of the beam correspondence capability of each antenna panel of the UE.

[0169] Step 4: The UE sends second indication information to the first device according to the configuration period, where the second indication information is used to indicate the current beam corresponding capability of the first antenna panel.

[0170] In an embodiment of the present application, the UE determines the current beam correspondence capabilities of different antenna panels based on the measurement results, and reports the current beam correspondence capabilities of different antenna panels according to the configuration period, so that the first device can better identify the current beam correspondence capabilities of different antenna panels of the UE.

[0171] For example, when the UE accesses the network, the first device determines that the initial beam correspondence capabilities of different antenna panels of the UE are all the first beam correspondence capabilities based on the first indication information, and the UE performs reference signal measurement based on the configuration period, and determines the current beam correspondence capability of each antenna panel based on the measurement results of different antenna panels, and then generates the second indication information, and sends the second indication information to the first device according to the configuration period. Specifically, if the measurement result is higher than the first limit value, the current beam correspondence capability of the antenna panel is determined to be the first beam correspondence capability; if the measurement result is higher than the second limit value and not higher than the first limit value, the current beam correspondence capability of the antenna panel is determined to be the second beam correspondence capability; if the measurement result is not higher than the second limit value, the current beam correspondence capability of the antenna panel is determined to be the third beam correspondence capability.

[0172] Embodiment 7

[0173] Embodiment 7 describes that when the first device is a test device, the UE sends first indication information based on a preset beam correspondence capability, so that the test device performs a test according to the initial beam correspondence capability of the antenna panel indicated by the first indication information. The specific steps are as follows:

[0174] Step 1: The UE sends first indication information to a test device, and the test device determines an initial beam correspondence capability of the first antenna panel according to the first indication information.

[0175] Step 2: The test equipment tests the initial beam correspondence capability of each antenna panel of the UE.

[0176] In the embodiment of the present application, the initial beam correspondence capability of the first antenna panel is determined based on the preset beam correspondence capability, and the beam correspondence capability of the antenna panel will not change subsequently. The test equipment tests the initial beam correspondence capability of the antenna panel, which means measuring the indicators that the initial beam correspondence capability needs to meet. Among them, the first beam correspondence capability needs to meet the two indicators of min peak EIRP and spherical coverage in the absence of uplink beam scanning, and the second beam correspondence capability needs to meet the three indicators of min peak EIRP, spherical coverage, and tolerance with the assistance of uplink beam scanning.

[0177] For example, the beam correspondence capability supported by different antenna panels of the UE in all frequency bands is determined as the first beam correspondence capability according to the first indication information. For each antenna panel, two indicators, minpeak EIRP and spherical coverage, need to be tested without uplink beam scanning.

[0178] Embodiment 8

[0179] Embodiment 8 describes that when the first device is a test device, the UE sends a second indication information based on a preset beam correspondence capability to indicate the current beam correspondence capability of different antenna panels of the UE, so that the test device tests the current beam correspondence capability of different antenna panels according to the second indication information. The specific steps are as follows:

[0180] Step 1: The UE sends first indication information to a test device, and the test determines an initial beam correspondence capability of the first antenna panel according to the first indication information.

[0181] Step 2: The test device requests to report the current beam correspondence capability of the first antenna panel.

[0182] Step 3: The UE generates second indication information based on the preset beam corresponding capability, and sends the second indication information to the test device.

[0183] Step 4: The testing device tests the current beam corresponding capability of the first different antenna panels indicated by the second indication information.

[0184] In the embodiment of the present application, the beam correspondence capabilities of the antenna panels of the UE are different. When the UE initially accesses the network, the initial beam correspondence capabilities of the different antenna panels of the UE can be indicated as the same beam correspondence capability. When each antenna panel is tested later, the test device requests the beam correspondence capability of the antenna panel from the UE, and then tests the beam correspondence capability of the requested antenna panel.

[0185] For example, the test device determines that the initial beam correspondence capability of the first antenna panel is the second beam correspondence capability based on the first indication information. For each measurement point, the test device requests the UE to report the current beam correspondence capability of each antenna panel, and then the UE reports the current beam correspondence capability of each antenna panel. If the current beam correspondence capability of antenna panel 1 is the first beam correspondence capability and the current beam correspondence capability of antenna panel 2 is the second beam correspondence capability, the test device performs a test based on the reported current beam correspondence capability of each antenna panel, that is, antenna panel 1 tests the two indicators of min peak EIRP and spherical coverage without uplink beam scanning, and antenna panel 2 tests the three indicators of min peak EIRP, spherical coverage, and tolerance with the assistance of uplink beam scanning.

[0186] Embodiment 9

[0187] Embodiment 9 describes that when the first device is a test device, the UE sends the second indication information based on the test result, dynamically indicates the current beam correspondence capability of the first antenna panel, and enables the test device to perform a test according to the current beam correspondence capability of the antenna panel indicated by the second indication information. The specific steps are as follows:

[0188] Step 1: The UE sends first indication information to a test device, and the test device determines an initial beam correspondence capability of the first antenna panel according to the first indication information.

[0189] Step 2: The test device requests the UE to report the current beam correspondence capability of the first antenna panel.

[0190] Step 3: Based on the current test result and in accordance with the determination rule of the beam correspondence capability of each antenna panel of the UE, the UE determines the current beam correspondence capability of the first antenna panel and generates second indication information.

[0191] Step 4: The UE sends second indication information to the test device.

[0192] Step 5: The testing device tests the current beam corresponding capability of the first antenna panel indicated by the second indication information.

[0193] In the embodiment of the present application, the beam correspondence capabilities of the antenna panels of the UE are different. When the UE initially accesses the network, the initial beam correspondence capabilities of the different antenna panels of the UE can be indicated as the same beam correspondence capabilities. When each antenna panel is tested later, the test device requests the beam correspondence capability of the antenna panel from the UE again. The UE dynamically indicates the current beam correspondence capabilities of the different antenna panels based on the test results, and then the test device tests the current beam correspondence capabilities of the different antenna panels dynamically indicated by the UE.

[0194] In a specific implementation manner, the first device is a test device; and the UE sends indication information to the test device, including:

[0195] The UE sends first indication information to the test device, where the initial beam corresponding capability of the first antenna panel indicated by the first indication information is the second beam corresponding capability or the third beam corresponding capability;

[0196] The UE receives, from the test device, a request for requesting the UE to send a beam corresponding capability of the first antenna panel;

[0197] The UE sends second indication information to the test device, and the current beam correspondence capability of the first antenna panel indicated by the second indication information is updated from the second beam correspondence capability to the first beam correspondence capability, or is updated from the third beam correspondence capability to the second beam correspondence capability.

[0198] In the embodiment of the present application, considering that the test of the first beam correspondence capability can be implemented without uplink beam scanning, while the test of the second beam correspondence capability requires the assistance of uplink beam scanning, the second beam correspondence capability test is more complicated than the first beam correspondence capability test. Therefore, in order to reduce the complexity of the test, the UE needs to satisfy the update order when reporting the current beam correspondence capability to the test device, so that the test process of the test device for the beam correspondence capability is a process from complex to simple.

[0199] In the specific implementation, the following three situations are included: 1) When the initial beam correspondence capability of the first antenna panel is the first beam correspondence capability, the current beam correspondence capability is not allowed to be the second beam correspondence capability during the test. At this time, the test device no longer requests the UE to indicate the current beam correspondence capability, and the test device performs the test according to the first beam correspondence capability; 2) When the initial beam correspondence capability of the first antenna panel is the second beam correspondence capability, the current beam correspondence capability is not allowed to be the third beam correspondence capability during the test. The test device requests the UE to indicate the current beam correspondence capability. At this time, the UE indicates that the current beam correspondence capability may be the second beam correspondence capability or the first beam correspondence capability; 3) When the initial beam correspondence capability of the first antenna panel is the third beam correspondence capability, the test device requests the UE to indicate the current beam correspondence capability. At this time, the current beam correspondence capability indicated may be any one of the third beam correspondence capability, the second beam correspondence capability, and the first beam correspondence capability.

[0200] Second, see Figure 3 , Figure 3 A flowchart of another information indication method provided in an embodiment of the present application is shown. Figure 3 As shown, the method comprises the following steps:

[0201] Step S310: The first device receives indication information sent by a user equipment UE, where the indication information is used to indicate or determine a beam corresponding capability of a first antenna panel of the UE, where the first antenna panel is one of multiple antenna panels of the UE;

[0202] Step S320: The first device determines the beam corresponding capability of the first antenna panel based on the indication information;

[0203] The beam correspondence capability of the first antenna panel is one of a first beam correspondence capability, a second beam correspondence capability, and a third beam correspondence capability:

[0204] The first beam correspondence capability is used to indicate that beam correspondence is supported and no uplink beam scanning assistance is required;

[0205] The second beam correspondence capability is used to indicate that beam correspondence is supported and uplink beam scanning assistance is required;

[0206] The third beam correspondence capability is used to indicate that beam correspondence is not supported.

[0207] In the embodiment of the present application, the first device may be Figure 1 The network side device 12, such as a base station or a test device, wherein examples of the network side device 12 and can be found in the above text and will not be repeated here.

[0208] After the first device receives the indication information sent by the user equipment UE, it distinguishes the beam correspondence capabilities of the different antenna panels of the UE according to the indication information. The UE and the first device communicate according to the beam correspondence capabilities of the different antenna panels of the UE, thereby ensuring the beam correspondence requirements and helping to stabilize the communication link and communication quality. In an embodiment of the present application, the UE can not only send indication information to the first device after accessing the network, but also send indication information to the first device when the beam correspondence capability changes due to hardware performance changes or measurement performance changes, so that the network side device can promptly know the beam correspondence capabilities of the different antenna panels of the UE, which is helpful to stabilize the communication link and communication quality. In addition, the beam correspondence capabilities of multiple antenna panels of the UE may be different. The embodiment of the present application proposes to report the beam correspondence capabilities of different antenna panels of the UE, so that it does not require the performance parameters of all antenna panels of the UE to remain consistent, thereby expanding the implementation form of the UE.

[0209] In a specific implementation, the indication information includes at least one of the following:

[0210] first indication information, where the first indication information is used to indicate an initial beam corresponding capability of the first antenna panel;

[0211] second indication information, where the second indication information is used to indicate a current beam corresponding capability of the first antenna panel;

[0212] The third indication information includes at least one of a limit value and a determination rule of a beam corresponding capability supported by each antenna panel of the UE.

[0213] In a specific implementation, the indication information includes third indication information, and the first device determines the beam corresponding capability of the first antenna panel based on the indication information, including:

[0214] The first device obtains a measurement result of the first antenna panel;

[0215] The first device determines a current beam correspondence capability of the first antenna panel according to the third indication information and a measurement result of the first antenna panel.
