Abstract
Description
Technical Field
[0001] This application belongs to the field of wireless communication technologies, and particularly relates to a method for determining beam information, a terminal, and a network-side device. Background Art
[0002] When the bandwidth of a frequency band is large, due to the differences in signal propagation characteristics at different frequency positions, beam squint may occur. For example, there is a deviation in the beam direction between the edge frequency points and the center frequency point of a large-bandwidth frequency band. When the network performs beam training based on the center frequency point and selects the optimal beam, and uses this optimal beam to transmit the channel across the entire bandwidth, the beam direction at the edge frequency points will deviate, resulting in deterioration of the beam link quality.
[0003] In the Third Generation Partnership Project (3GPP), the concepts of Independent Beam Management (IBM) and Common Beam Management (CBM) are introduced to describe two different operating modes under inter-band Carrier Aggregation (CA) in Frequency Range (FR) 2.
[0004] Among them, IBM means that the User Equipment (UE) can independently select the optimal beam for the Primary Component Carrier (PCC) and the Secondary Component Carrier (SCC) through independent beam management. In this case, different Component Carriers (CCs) can have relatively optimal transceiver performance, but the disadvantage is that the signaling overhead is large and the UE architecture design is also more complex.
[0005] CBM means that only the PCC of the UE performs the beam management process, and the SCC directly applies the configuration of the PCC. The advantage of this method is that it saves signaling overhead and simplifies the UE structure to reduce costs. However, since FR2 uses hybrid beamforming, with this configuration method, the beams of the PCC and the SCC use the same phase shifter configuration, which may cause a certain deviation in the beam direction of the SCC relative to the PCC, resulting in the so-called "beam squint" and performance degradation.
[0006] It can be seen that the beam squint phenomenon may lead to a decline in the beam link performance in the case of large bandwidth or cross-frequency bands. Therefore, if the beam management result of the PCC is directly applied to the SCC, the beam link between the network and the UE on the SCC may be misaligned and the performance may be poor.

[0035] Next, in conjunction with the accompanying drawings, the method for determining beam information provided in the embodiments of the present application will be described in detail through some embodiments and their application scenarios.
[0036] Figure 2 FIG. shows a schematic flowchart of a method for determining beam information in the embodiments of the present application. The method 200 may be executed by a terminal. In other words, the method may be executed by software or hardware installed on the terminal. As Figure 2 shown, the method may include the following steps.
[0037] S210, the terminal measures the signal quality on at least one first reference signal (RS) resource to be measured according to the received configuration information, where the first RS resource to be measured corresponds to a first object.
[0038] In the related art, when performing beam measurement, the network-side device configures the configuration information of beam reporting for the terminal. The configuration information is associated with a reference signal resource setting (RS resource setting). The setting includes at least one reference signal resource set (RS resource set), and each set includes at least one RS resource, such as a synchronization signal / physical broadcast channel signal block (or synchronization signal block) (Synchronization Signal and PBCH Block, SSB) resource or a channel state information reference signal (Channel State Information Reference Signal, CSI-RS) resource. The terminal measures the layer 1 reference signal received power (Reference Signal Received Power, RSRP) and / or the layer 1 signal-to-noise and interference ratio (Signal-to-noise and Interference Ratio, SINR) of each RS resource, and reports at least one optimal measurement result to the network. The reported content includes the SSB resource indicator (SSB Resource Indicator, SSBRI) or the CSI-RS resource indicator (CSI-RS Resource Indicator, CRI), and L1-RSRP and / or L1-SINR. In addition, in the configuration information of beam reporting, it can be specified whether the report is a group-based beam report. If it is a non-group-based beam report, the UE will report at least one optimal beam and its quality for the network side to determine the beam used to send channels or signals to the UE. If it is a group-based beam report, the UE will report a pair of beams and their quality, and when the network side uses this pair of beams to send information to the UE, the UE can receive it simultaneously.
[0039] In the present application, the network-side device may include a first RS resource to be measured in the configuration information, and the first RS resource to be measured corresponds to a first object. For example, the configuration information received by the terminal may include the configuration information of CSI reporting. For example, CSI-ReportConfig includes the first RS resource to be measured corresponding to the first object in the configuration information of CSI reporting.
[0040] Among them, the first RS resource to be measured corresponding to the first object may include one of the following:
[0041] (1) The first RS resource to be measured in the first set of RS resources to be measured (resource set) corresponding to the first object;
[0042] (2) The first RS resource to be measured in the first resource configuration (resource config or resource setting) of RS resources to be measured corresponding to the first object;
[0043] (3) The first RS resource to be measured in the first group of RS resources to be measured corresponding to the first object.
[0044] Among them, the corresponding relationship between the first object and the first RS resource to be measured can be determined by the following methods:
[0045] (1) In the above-mentioned first RS resource to be measured, first resource setting of RS resources to be measured, first set of RS resources to be measured (set), or first group of RS resources to be measured, add the number or ID of the first object. For example, in the reference signal resource setting (setting), or the set of RS resources included in the RS resource setting, or the RS resources in the set of RS resources, or the description information of the RS resource group contains the number or ID of the first object, and this RS resource setting, set of RS resources, RS resource group or RS resource corresponds to the first object;
[0046] (2) Configure the first RS resource to be measured, first resource setting of RS resources to be measured, first set of RS resources to be measured (set), or first group of RS resources to be measured in the configuration information of the first object; that is, configure the corresponding first RS resource to be measured in the configuration information of the first object, which can be one or more RS resources, or a resource setting of one RS resource, that is, indicate that all RS resources in this resource setting of RS resources are corresponding to the first object, or, it can also be one or more sets of RS resources or RS resource groups.
[0047] (3) In the configuration information of the above CSI report, include the association relationship or mapping relationship between the above-mentioned first RS resource to be measured, first resource setting of RS resources to be measured, first set of RS resources to be measured (set), or first group of RS resources to be measured and the number or ID of the first object.
[0048] (4) The network - side device indicates, through signaling, the association relationship or mapping relationship between the above - mentioned first RS resource to be measured, the setting of the first RS resource to be measured, the set of the first RS resources to be measured, or the first group of RS resources to be measured and the number or ID of the first object. For example, the network - side device indicates the association relationship or mapping relationship through a Medium Access Control (MAC) Control Element (CE) or Downlink Control Information (DCI).
[0049] Among them, the first object includes, but is not limited to, one of the following: (1) cell; (2) Bandwidth Part (BWP); (3) sub - band; (4) band; (5) Transmission Reception Point (TRP); (6) UE panel; (7) carrier.
[0050] That is to say, a first object can be a cell, BWP, sub - band, band, TRP, carrier, or UE panel, or a combination thereof.
[0051] S212, the terminal reports a beam report to the network - side device according to the measurement result, where the beam report includes the first beam information of the first object.
[0052] In the embodiments of this application, the terminal can send a beam report according to the received configuration information above. The beam report can include the first beam information corresponding to the first object determined by the UE. Among them, the first beam information can include the index information of one of the at least one RS resource to be measured, such as SSBRI or CRI, etc., and / or can also include the quality information of one of the at least one RS resource to be measured, such as L1 - RSRP and / or L1 - SINR. For example, the beam report can include the correspondence between the index information of one RS resource to be measured and the quality information measured on this RS resource.
[0053] S214, the terminal sends the Sounding Reference Signal (SRS) corresponding to the second object.
[0054] In the embodiments of this application, the terminal sends the SRS corresponding to the second object, so that the network - side device can measure the SRS to determine the target beam information on the second object.
[0055] In an embodiment of the present application, corresponding to a first object, the second object may include, but is not limited to, one of the following: (1) a cell; (2) a Bandwidth Part (BWP); (3) a sub-band; (4) a band; (5) a Transmission Reception Point (TRP); (6) a UE panel; (7) a carrier wave.
[0056] For example, the first object may be a first cell, and the second object may be a second cell, or the first object is a first carrier wave and the second object is a second carrier wave, etc.
[0057] In a possible implementation manner, the terminal may transmit the SRS on the second object according to the SRS resource information configured by the network-side device.
[0058] In a possible implementation manner, the terminal may determine the second beam information used for transmitting the SRS on the second object according to the first beam information corresponding to the first object determined in step S212, and then use this second beam information to transmit the SRS on the second object.
[0059] For example, after the terminal measures each CSI-RS resource in the CSI-RS resource on band1 and includes CRI1, that is, the measurement result of CSI-RS resoure1, in the transmitted beam report, the second beam information used for transmitting the SRS on band2 may be determined according to the beam information of CSI-RS resource1. Among them, the Rx beam during the measurement of CSI-RS resource1 and the Tx beam used for transmitting the SRS on band2 may have beam consistency (that is, the direction of the Rx beam is the direction of the Tx beam). For example, the Rx beam of CSI-RS resource1 is used as the Tx beam for transmitting the SRS on band2, or there is no beam consistency, and the Tx beam for transmitting the SRS on band2 is determined by adjusting according to the Rx beam of CSI-RS resource1. For example, the beam in the adjacent direction to the Rx beam of CSI-RS resource1 is used as the Tx beam for transmitting the SRS on band2.
[0060] In another possible implementation, the terminal can also determine the second beam information used for transmitting SRS on the second object according to the first target beam information. For example, after receiving the beam report reported by the terminal, the network-side device can select one piece of first beam information from it as the first target beam information and indicate it to the terminal. The terminal can determine the second beam information used for transmitting SRS on the second object according to the first target beam information indicated by the network-side device. For example, in the beam report of band1, CRI1 and CRI2 are included, that is, the measurement results of CSI-RS resource1 and CSI-RS resource2. If the source RS in the first target beam information indicated by the network-side device is CSI-RS resource1, the terminal determines the beam information used for transmitting SRS on band2 according to the beam information of CSI-RS resource1. For example, the Rx beam of CSI-RS resource1 is used as the Tx beam for transmitting SRS on band2, or the Tx beam for transmitting SRS on band2 is determined by adjusting according to the Rx beam of CSI-RS resource1. For example, the beam in the adjacent direction to the Rx beam of CSI-RS resource1 is used as the Tx beam for transmitting SRS on band2.
[0061] In another possible implementation, the network-side device may indicate the beam information of the SRS resources in the configured SRS resource information, that is, indicate the beam information of the SRS resources on the second object, and the terminal uses this beam information to send SRS on the second object. For example, after receiving the beam report reported by the terminal, the network-side device may indicate the beam information of the SRS resources on the second object for the terminal according to the first beam information in the beam report. For example, in the beam report of band1, CRI1 is included, that is, the measurement result of CSI-RS resource1. The network-side device indicates the beam information for the SRS resources of band2 according to this measurement result. If the UE uses the Rx beam when receiving CSI-RS resource1, the UE can determine the Tx beam of the SRS resources according to the beam information indicated by the network-side device for the SRS resources on band2. This Tx beam may have beam consistency with the Rx beam of CSI-RS resource1, or this Tx beam is located in the adjacent direction of the Rx beam of CSI-RS resource1. In the above possible implementation, when the terminal sends the SRS on the second object, optionally, the SRS may be sent using the second beam information on multiple SRS resources. Optionally, the second beam information may include multiple beam information. The beam information used to send SRS on different SRS resources may be the same or not completely the same. For example, if the second object corresponds to 3 SRS resources, the beam information used by the terminal to send SRS on the 3 SRS resources may be completely different, or the SRS may be sent using the same beam information on 2 of the SRS resources and using another beam information on another SRS resource, or the SRS may be sent using the same beam information on all 3 SRS resources.
[0062] In another possible implementation, the terminal may also determine the fourth beam information used to send SRS on the second object according to the third beam information of the first SRS resource corresponding to the first object, and then use the fourth beam information to send SRS on the second object.
[0063] In the above possible implementation, the third beam information may be determined according to at least one of the following methods:
[0064] (1) Determine according to the first beam information.
[0065] The terminal may determine the third beam information of the first SRS resource according to at least one first to-be-measured RS resource in the beam report corresponding to the first object, and then determine the fourth beam information used to send SRS on the second object according to the third beam information.
[0066] For example, after the terminal measures each CSI-RS resource in the CSI-RS resource on band1 and includes CRI1, that is, the measurement result of CSI-RS resource1, in the sent beam report, the first SRS resource on band1 is first determined. The beam information (i.e., the third beam information) of this first SRS resource is determined according to the beam information of CSI-RS resource1. For example, the Rx beam of CSI-RS resource1 is used as the Tx beam of the first SRS resource, or CSI-RS resource1 is used as the source RS of the beam information of the first SRS resource. Then, the beam information used for sending the SRS on band2 is determined according to the beam information of the first SRS resource. For example, the Tx beam of the first SRS resource is used as the Tx beam for sending the SRS on band2, or the Tx beam for sending the SRS on band2 is determined by adjusting according to the Tx beam of the first SRS resource. For example, the beam in the adjacent direction to the Tx beam of the first SRS resource is used as the Tx beam for sending the SRS on band2.
[0067] (2) Determined according to the first target beam information.
[0068] For example, after receiving the beam report reported by the terminal, the network-side device can select a first beam information from it as the first target beam information and indicate it to the terminal. The terminal can determine the third beam information of the first SRS resource according to the first target beam information indicated by the network-side device, and then determine the fourth beam information used for sending the SRS on the second object according to the third beam information. For example, in the beam report on band1, CRI1 and CRI2 are included, that is, the measurement results of CSI-RS resource1 and CSI-RS resource2. If the source RS in the first target beam information indicated by the network-side device is CSI-RS resource1, the terminal first determines the first SRS resource on band1 according to CSI-RS resource1. For example, the Rx beam of CSI-RS resource1 is used as the Tx beam of the first SRS resource (i.e., the third beam information), or CSI-RS resource1 is used as the source RS of the beam information of the first SRS resource. Then, the beam information used for sending the SRS on band2 is determined according to the beam information of the first SRS resource.
[0069] (3) Determined according to the beam information of the first SRS resource indicated by the network-side device.
[0070] The terminal uses the beam information of the first SRS resource indicated by the network-side device as the third beam information, and then determines the fourth beam information for transmitting the SRS on the second object according to the third beam information. For example, the network-side device may indicate the beam information of the first SRS resource in the configuration information of the first SRS resource of the first object.
[0071] For example, if the network-side device indicates that the Tx beam of the first SRS resource is beam1, the terminal may determine the Tx beam used for transmitting the SRS on the second object according to the beam information of the first SRS resource. For example, the Tx beam used for transmitting the SRS on the second object is also beam1, or the Tx beam used for transmitting the SRS on the second object is beam2 obtained by adjusting beam1.
[0072] Alternatively, the terminal may also combine two or three of the above three items to determine the first beam information used for transmitting the SRS on the second object. Details are not described herein again.
[0073] In each of the above possible implementation manners, optionally, before the terminal transmits the SRS corresponding to the second object, the method may further include: the terminal transmits a notification message indicating that the terminal is currently using the CBM mode; and / or, the terminal receives the first indication information of the network-side device, where the first indication information indicates that the terminal uses the CBM mode.
[0074] S216, the terminal receives the first target beam indication signaling sent by the network-side device.
[0075] After measuring the SRS signal on the SRS resource on the second object, the network-side device can determine the beam information of the network-side device on the second object, and thus can indicate the terminal through the first target beam indication signaling.
[0076] S218, the terminal determines the first target beam information of the first object and the second target beam information of the second object according to the first target beam indication signaling.
[0077] Through the technical solution provided by the embodiments of the present application, after the terminal measures the first to-be-measured RS resource corresponding to the first object and reports a beam report, it can send the SRS corresponding to the second object, so that the network-side device measures the SRS, and further determines the first target beam information of the first object and the second target beam information of the second object according to the measurement result of the SRS and the beam report of the first object reported by the terminal, thereby enabling the beam links between the terminal and the network-side device on the first object and the second object to be aligned. Especially for CBM mode terminals, it can avoid the so-called "beam squint" problem caused by the beam direction of the SCC having a certain deviation relative to the PCC, and improve the communication performance.
[0078] In a possible implementation manner of the embodiments of the present application, the first target beam information of the first object may be carried in the first target beam instruction and the second target beam information of the second object may not be carried. In this case, the terminal determines that the target beam information of the first object is the first target beam information carried by the first target beam indication signaling. Then, the terminal may determine the second target beam information of the second object according to the first target beam information.
[0079] Optionally, the terminal determines the second target beam information of the second object according to the first target beam information, including: the terminal obtains third target beam information corresponding to the first target beam information, where the third target beam information is the beam information used to send the SRS determined according to the first target beam information; the terminal determines the second target beam information according to the third target beam information.
[0080] That is to say, the terminal can determine the second target beam information according to the first target beam information in a corresponding manner to determining the second beam information or the fourth beam information used to send the SRS in S214. For example, the beam information used by the terminal to send the SRS is the second beam information obtained according to the first beam information on the first object, or the fourth beam information obtained according to the third beam information of the first SRS on the first object. After the network-side device receives the beam report corresponding to the first object, it indicates the first target beam information, and the first target beam information may be determined according to one of the first beam information (i.e., SSBRI / CRI) reported in the beam report. Then, the second target beam information on the second object may be determined according to one of the second beam information or the fourth beam information used when sending the SRS, where one of the second beam information or the fourth beam information is the same as one of the above first beam information, that is, it may be the beam information used to send the SRS determined according to one of the above first beam information.
[0081] For example, in the beam report of band1, the terminal includes CSI-RS resource1 and CSI-RS resource2. The sourceRS in the TCI state carried in the first target beam indication instruction sent by the network device is CSI-RS resource1. The terminal uses Rx beam1 to receive CSI-RS resource1. When the terminal sends the SRS of the second object, if it uses the Rx beam1 of CSI-RS resource1 as the Tx beam1 of the SRS resource of the second object, or determines the Tx beam2 of the first SRS resource according to Rx beam1 and then determines the Tx beam1 of the SRS of the second object according to Tx beam2, the terminal can determine the second target beam information of the second object according to the beam information used for sending the SRS (i.e., the third target beam information). For example, it can be determined that the second target beam information is the third target beam information, or the beam information obtained after adjusting the third target beam information.
[0082] For another example, if the second beam information used for sending the SRS is determined according to the first target beam information, the second target beam information of the second object can be directly determined according to the second beam information used for sending the SRS. For example, it can be determined that the second target beam information is the second beam information used for sending the SRS, or the beam information obtained after making certain adjustments to the second beam information used for sending the SRS.
[0083] In another possible implementation, the first target beam instruction may carry the second target beam information of the second object but not the first target beam information of the first object. In this case, the terminal determines the target beam information of the second object as the second target beam information carried in the first target beam indication signaling. Then, the terminal can determine the first target beam information of the first object according to the second target beam information.
[0084] For example, the terminal includes CSI-RS resource1 in the beam report of band1, and the terminal uses Rx beam1 to receive CSI-RS resource1. When the terminal sends the SRS of the second object, if the Tx beam1 of the SRS resource of the second object is determined according to the Rx beam1 of CSI-RS resource1, or the Tx beam2 of the first SRS resource is determined according to Rx beam1, and then the Tx beam1 of the SRS of the second object is determined according to Tx beam2, where Tx beam1 can be multiple beams adjacent to Rx beam1 or Tx beam2 in direction. After the network-side device measures the SRS of the second object on multiple beams, the optimal beam information of the SRS of the second object is obtained. When the network-side device uses the second target beam indication command to indicate the second target beam information, the second target beam information can be determined according to the optimal beam information of the SRS of the second object as described above (such as using the QCL source RS of the SRS resource with the optimal measurement result as the source RS of the second target beam information). Then, the terminal can determine the first target beam information according to the second target beam information. For example, the second target beam information is the first target beam information, or the beam information obtained after adjusting the second target beam information.
[0085] In another possible implementation, the first target beam instruction may carry the first target beam information of the first object and the second target beam information of the second object. The terminal determines that the target beam information of the first object is the first target beam information carried by the first target beam indication signaling, and the target beam information of the second object is the second target beam information carried by the first target beam indication signaling. For example, the first target beam indication signaling may carry the identifier of the first object and the first target beam information, as well as the identifier of the second object and the second target beam information.
[0086] In the above possible implementation manners, the first target beam information is one in the first beam pool configured by the network-side device for the first object; the second target beam information on the second object is one in the first beam pool, or the second target beam information on the second object is one in the second beam pool configured by the network-side device for the second object. For example, the TCI state or spatial relation information that may be included in the first target beam indication signaling is from a pool configured by the network-side device, and this pool may be configured to correspond only to the first object. And the second object may use the pool configured on the first object; or, the second target beam information of the second object may be from the pool configured by the network-side device corresponding to the second object.
[0087] In the above possible implementation manners, the first target beam information may include the identification information of the first target beam, for example, ID or number, etc., such as, TCI state ID; the second target beam information may include the identification information of the second target beam, for example, ID or number, etc., such as, TCI state ID.
[0088] In the embodiments of the present application, the first target beam indication signaling may be used to indicate or activate the first target beam information of the first object and the second target beam information of the second object. For example, it indicates that the terminal uses the first target beam information to communicate with the network-side device on the first object and uses the second target beam information to communicate with the network-side device on the second object.
[0089] In a possible implementation manner, after the terminal reports the beam report, the method may further include the following steps: the terminal updates the beam information of the first target object or updates the RS resource to be measured of the first target object, where the first target object includes at least one of the first object and the second object.
[0090] For example, the terminal may update the beam information of the first object or the RS resource to be measured of the first object according to the first beam information of the first object, and / or update the beam information of the second object or update the RS resource to be measured of the second object according to the second beam information used for sending SRS on the second object.
[0091] Optionally, before the terminal updates the beam information of the first target object or updates the RS resource to be measured of the first target object, the method further includes: the terminal receives the second target beam indication signaling sent by the network-side device, where the second target beam indication signaling indicates to update the beam information of the first target object or update the RS resource to be measured of the first target object.
[0092] That is to say, in the above possible implementation manners, the network-side device may indicate to update the beam information of the first object and / or the second object, or update the measured RS resources of the first object and / or the second object. For example, the network-side device configures the first measured RS resources corresponding to the first object to include: CSI-RS resource1, CSI-RS resource2, CSI-RS resource3, and CSI-RS resource4. The terminal measures the first measured RS resources, selects 2 CSI-RS resources with better quality according to the measurement results, and reports CRI1 and CRI2 in the beam report. The corresponding to CRI1 and CRI2 are UERx beam1 and Rx beam2. According to this beam report, the network-side device sends a second target beam indication signaling, and the first target beam information of the first object is carried in the second target beam indication signaling. For example, the first target beam information is TCIstate 1, and the source RS of TCI state 1 is CSI-RS resource1. Then the terminal updates the first target beam information of the first object to TCI state1, that is, uses the Rx beam (Rxbeam1) of its source RS (CSI-RS resource1) to transmit the channel with the network. It can also update the first measured RS resources to the source RS of TCIstate 1, that is, CSI-RS resource1, according to the network command. When the terminal performs beam measurement next time, it only needs to measure CSI-RS resource1 corresponding to the first object, thereby saving measurement resources.
[0093] In practical applications, the second target beam indication signaling and the above first target beam indication signaling may be the same signaling, that is, the beam indication signaling is used to indicate, activate, and update the beam information, or they may not be the same signaling, which is not specifically limited in the embodiments of the present application.
[0094] In a possible implementation, the first target beam information of the first object may be carried in the second target beam indication signaling, and the second target beam information of the second object is not carried. In this case, the terminal may update the beam information of the first object to the first target beam information, or update the first measurement RS resource of the first object to the RS resource corresponding to the first target beam information. Alternatively, the terminal may update the beam information of the first object to the first target beam information or update the first measurement RS resource of the first object to the RS resource corresponding to the first target beam information, and determine the second target beam information of the second object according to the first target beam information, update the beam information of the second object to the second target beam information, or update the second measurement RS resource of the second object to the RS resource corresponding to the second target beam information. For example, the terminal may obtain the first target beam information according to the first target beam indication signaling, and then determine the second target beam information according to the first target beam information. Wherein, the second target beam information may be the beam information used for transmitting the SRS determined according to the first target beam information. Alternatively, there is a preset correspondence between the first target beam information and the second target beam information, and this correspondence may be indicated by the network-side device or may also be agreed upon by the protocol. For example, the protocol agrees or the network-side device configures the offset information between the first target beam information and the second target beam information, and the terminal may determine the corresponding second target beam information according to the first target beam information.
[0095] In another possible implementation, the second target beam indication signaling may carry the second target beam information of the second object without carrying the first target beam information of the first object. In this case, the terminal may update the beam information of the second object to the second target beam information or update the second to-be-measured RS resource of the second object to the RS resource corresponding to the second target beam information. Alternatively, the terminal may update the beam information of the second object to the second target beam information or update the second to-be-measured RS resource of the second object to the RS resource corresponding to the second target beam information, and determine the first target beam information of the first object according to the second target beam information, and update the beam information of the first object to the first target beam information or update the first to-be-measured RS resource of the first object to the RS resource corresponding to the first target beam information. For example, the second target beam information is determined according to the optimal beam information of the SRS resource on the second object, and then the first target beam information is determined according to the second target beam information. Alternatively, there is a preset correspondence between the first target beam information and the second target beam information. This correspondence may be indicated by the network-side device or may also be agreed upon by the protocol. For example, the protocol agrees or the network-side device configures the offset information between the first target beam information and the second target beam information, and the terminal can determine the corresponding first target beam information according to the second target beam information.
[0096] In yet another possible implementation, the second target beam indication signaling may carry the first target beam information of the first object and the second target beam information of the second object. In this case, the terminal may, according to the indication of the second target beam indication signaling, update the beam information of the first object to the first target beam information or update the first to-be-measured RS resource of the first object to the RS resource corresponding to the first target beam information; update the beam information of the second object to the second target beam information or update the second to-be-measured RS resource of the second object to the RS resource corresponding to the second target beam information. For example, the correspondence between the identification information of the first target beam and the identification information of the first object, and the correspondence between the identification information of the second target beam and the identification information of the second object may be carried in the second target beam indication signaling. Alternatively, the second target beam indication signaling may not carry the identification information of the first object and the identification information of the second object, but carry the first target beam information and the second target beam information in a preset order or at a preset position according to the protocol agreement or the configuration of the network-side device, indicating that the first target beam information corresponds to the first object and the second target beam information corresponds to the second object.
[0097] In a possible implementation, the second target beam indication signaling carrying the first target beam information of the first object may include: the second target beam indication signaling carrying the first common TCI state of the first member carrier group, where the first object belongs to or includes the first member carrier group.
[0098] The second target beam indication signaling carrying the second target beam information of the second object may include: the second target beam indication signaling carrying the second common TCI state of the second member carrier group, where the second object belongs to or includes the second member carrier group.
[0099] The second target beam indication signaling carrying the first target beam information of the first object and the second target beam information of the second object includes: the second target beam indication signaling carrying the first common TCI state of the first member carrier group and the second common TCI state of the second member carrier group, where the first object belongs to or includes the first member carrier group, and the second object belongs to or includes the second member carrier group.
[0100] In a possible implementation, the second target beam indication signaling updating the beam information of the first target object or updating the measured RS resource of the first target object includes at least one of the following:
[0101] (1) The second target beam indication signaling instructs the first transmission configuration indication (TCI) state of the first target object to be updated to a target TCI state. The first TCI state is the TCI state of the first target object indicated by the network side device in the most recent indication, that is, the currently used TCI state, or the first TCI state is the TCI state of the first target object activated by the network side device in the most recent activation, that is, the TCI state in the currently active state.
[0102] In this possible implementation, the network side device may carry an identifier of the target TCI state in the second target beam indication signaling.
[0103] (2) The second target beam indication signaling instructs the RS resource of QCL type D in the first TCI state of the first target object to be updated to a first target RS resource.
[0104] In this possible implementation, the network-side device may update the RS resource of QCL-TypeD in the first TCI state to the first target RS resource through the second target beam indication signaling. For example, the network-side device updates the QCL-TypeD source RS resource in the first TCI state through a MAC CE command. The first TCI state may be the TCI state indicated by the network-side device in the beam indication signaling most recently, or the TCI state activated by the network-side device most recently, or the network-side device indicates the updated TCI state to the UE using the beam indication signaling or the activation command.
[0105] For example, if the first target beam information of the first object is carried in the second target beam indication signaling, it indicates that the RS resource of QCL-TypeD in the first TCI state of the first object is updated to the RS resource corresponding to the first target beam information. If the second target beam information of the second object is carried in the second target beam indication signaling, it indicates that the RS resource of QCL-TypeD in the first TCI state of the second object is updated to the RS resource corresponding to the second target beam information. If the first target beam information of the first object and the second target beam information of the second object are carried in the second target beam indication signaling, it indicates that the RS resource of QCL-TypeD in the first TCI state of the first object is updated to the RS resource corresponding to the first target beam information, and the RS resource of QCL-TypeD in the first TCI state of the second object is updated to the RS resource corresponding to the second target beam information.
[0106] In a possible implementation, when the first object belongs to or includes the first member carrier group, the terminal may update the beam information of each member carrier in the first member carrier group based on the updated beam information of the first object.
[0107] When the second object belongs to or includes the second member carrier group, the terminal updates the beam information of each member carrier in the second member carrier group based on the updated beam information of the second object.
[0108] In the embodiments of the present application, for the CA scenario, the network-side device may configure at least one set of component carriers (CCs), and each set of CCs may correspond to different objects. For example, different bands. The target beam information (the first target beam information or the second target beam information) indicated by the second target beam indication signaling is used to update the beam information of all CCs and all BWPs in a set of CCs simultaneously. Alternatively, multiple sets of CCs may be associated. For example, if an object includes multiple sets of CCs, the target beam information (the first target beam information or the second target beam information) indicated by the second target beam indication signaling is used to determine the beam information or RS resources of each set of CCs in the object. For example, the QCL-TypeD RS resource, that is, the source RS resource of QCL-TypeD, means that the QCL-TypeD RS resources between groups are different, and the QCL-TypeD RS resources of each CC within a group may be the same RS resource or different RS resources.
[0109] In the case where the number M of downlink (DL) TCI states configured by the network-side device is greater than 1 and / or the number N of uplink (UL) TCI states is greater than 1, the second target beam indication signaling may indicate the TCI states of different objects, where each TCI state is used to determine the beam information of multiple channels or RSs on at least one CC for each object.
[0110] In a possible implementation, the method may further include at least one of the following:
[0111] (1) Activate or use the first object when the signal quality on the at least one first RS resource to be measured meets the first preset condition. For example, when the L1-RSRP on the at least one first RS resource to be measured reaches the preset threshold, the terminal may activate or use the first object.
[0112] (2) Send a first notification to the network-side device when the signal quality on the at least one first RS resource to be measured meets the first preset condition, where the first notification indicates that the first object is in an activated state or a used state. For example, when the L1-RSRP on the at least one first RS resource to be measured reaches the preset first threshold, the terminal may activate or use the first object and send a first notification to the network-side device, where the first notification may be carried in the above beam report or may not be carried in the beam report.
[0113] (3) When the signal quality on the at least one first RS resource to be measured meets a first preset condition, send a second notification to the network-side device, where the second notification indicates that the signal quality on the at least one first RS resource to be measured meets the first preset condition. The second notification may or may not be carried in the beam report.
[0114] (4) When the signal quality on the at least one first RS resource to be measured does not meet the first preset condition, deactivate or do not use the first object; for example, when the L1-RSRP on the at least one first RS resource to be measured is lower than a preset second threshold, the terminal may deactivate or not use the first object.
[0115] (5) When the signal quality on the at least one first RS resource to be measured does not meet the first preset condition, send a third notification to the network-side device, where the third notification indicates that the first object is in a deactivated state or a non-used state; for example, when the L1-RSRP on the at least one first RS resource to be measured is lower than a preset second threshold, the terminal may deactivate or not use the first object and send a third notification to the network-side device, where the third notification may or may not be carried in the beam report.
[0116] (6) When the signal quality on the at least one first RS resource to be measured does not meet the first preset condition, send a fourth notification to the network-side device, where the fourth notification indicates that the signal quality on the at least one first RS resource to be measured does not meet the first preset condition; where the fourth notification may or may not be carried in the beam report.
[0117] (7) When the signal quality of the first beam information meets a second preset condition, activate or use the first object; for example, when the first beam information, i.e., the L1-RSRP, reaches a preset third threshold, the terminal may activate or use the first object.
[0118] (8) When the signal quality of the first beam information meets a second preset condition, send the first notification to the network-side device; for example, when the first beam information, i.e., the L1-RSRP, reaches a preset third threshold, the terminal may activate or use the first object and send the first notification to the network-side device, where the first notification may be carried in the beam report. For example, the terminal may select the first beam information whose signal quality meets the second preset condition in the beam report for reporting. Or, the terminal may also specifically send the first notification to the network-side device.
[0119] (9) When the signal quality of the first beam information meets the second preset condition, send a fifth notification to the network-side device, where the fifth notification indicates that the signal quality of the first beam information meets the second preset condition; the fifth notification can be carried in a beam report. For example, the terminal can select the first beam information with signal quality meeting the second preset condition in the beam report for reporting. Alternatively, the terminal can also specifically send a fifth notification to the network-side device.
[0120] (10) When the signal quality of the first beam information does not meet the second preset condition, deactivate or do not use the first object. For example, when the first beam information, i.e., L1-RSRP, is lower than a preset fourth threshold, the terminal can deactivate or not use the first object.
[0121] (11) When the signal quality of the first beam information does not meet the second preset condition, send the third notification to the network-side device. For example, when the first beam information, i.e., L1-RSRP, is lower than a preset fourth threshold, the terminal can deactivate or not use the first object and send the third notification to the network-side device.
[0122] (12) When the signal quality of the first beam information does not meet the second preset condition, send a sixth notification to the network-side device, where the sixth notification indicates that the signal quality of the first beam information does not meet the second preset condition;
[0123] (13) When the performance of using the first target beam information to transmit a channel or a reference signal meets the third preset condition, the terminal activates or uses the first object, where the first target beam information is the beam information of the first object indicated or activated by the network-side device.
[0124] (14) When the performance of using the first target beam information to transmit a channel or a reference signal meets the third preset condition, the terminal sends the first notification;
[0125] (15) When the performance of using the first target beam information to transmit a channel or a reference signal meets the third preset condition, the terminal sends a seventh notification to the network-side device, where the seventh notification indicates that the performance of the terminal in using the first target beam information to transmit a channel or a reference signal meets the third preset condition;
[0126] (16) When the performance of using the first target beam information to transmit a channel or a reference signal does not meet the third preset condition, the terminal deactivates or does not use the first object;
[0127] (17) When the performance of transmitting a channel or a reference signal using the first target beam information does not meet the third preset condition, the terminal sends the third notification.
[0128] (18) When the performance of transmitting a channel or a reference signal using the first target beam information does not meet the third preset condition, the terminal sends an eighth notification to the network device, where the eighth notification indicates that the performance of the terminal in transmitting a channel or a reference signal using the first target beam information does not meet the third preset condition.
[0129] (19) The terminal activates or uses the first object according to the first signaling sent by the network device.
[0130] (20) The terminal deactivates or does not use the first object according to the second signaling sent by the network device.
[0131] In a possible implementation, the method may further include at least one of the following:
[0132] (1) When the performance of transmitting a channel or a reference signal using the second target beam information meets the fourth preset condition, the terminal activates or uses the second object, where the second target beam information is the beam information of the second object indicated or activated by the network device. For example, the second target beam information of the second object carried in the above first target beam indication signaling; or, the second target beam information is the beam information of the second object determined according to the first target beam information of the first object indicated or activated by the network device. For example, the first target beam indication signaling carries the first target beam information of the first object, and the terminal can determine the second target beam information of the second object according to the first target beam information.
[0133] (2) When the performance of transmitting a channel or a reference signal using the second target beam information meets the fourth preset condition, the terminal sends a ninth notification to the network device, where the ninth notification indicates that the second object is in an activated state or a used state. For example, when the performance of the terminal in transmitting a channel or a reference signal using the second target beam information meets the fourth preset condition, the terminal activates or uses the second object and sends a ninth notification to the network device.
[0134] (3) When the performance of transmitting a channel or a reference signal using the second target beam information meets the fourth preset condition, the terminal sends a tenth notification to the network device, where the tenth notification indicates that the performance of the terminal in transmitting a channel or a reference signal using the second target beam information meets the fourth preset condition.
[0135] (4) If the performance of using the second target beam information transmission channel or reference signal does not meet the fourth preset condition, the terminal deactivates or does not use the second object.
[0136] (5) If the performance of using the second target beam information transmission channel or reference signal does not meet the fourth preset condition, the terminal sends an eleventh notification to the network-side device, where the eleventh notification indicates that the second object is in a deactivated state or a non-used state.
[0137] (6) If the performance of using the second target beam information transmission channel or reference signal does not meet the fourth preset condition, the terminal sends a twelfth notification to the network-side device, where the twelfth notification indicates that the performance of the terminal in using the second target beam information transmission channel or reference signal does not meet the fourth preset condition.
[0138] (7) The terminal activates or uses the second object according to the third signaling sent by the network-side device.
[0139] (8) The terminal deactivates or does not use the second object according to the fourth signaling sent by the network-side device.
[0140] For example, the first object is band1 and panel1, and the second object is band2 and panel2, that is, the two panels of the UE support different bands respectively. The UE uses panel1 to measure the CSI-RS resources on band1 and uses panel2 to measure the SRS resources on band2 to send SRS. The UE reports the measurement results in the beam report, that is, the CRI and L1-RSRP corresponding to band1. The UE can determine whether to activate or use the panel where band1 is located according to the L1-RSRP value corresponding to band1. The UE can also determine whether to activate or use the panel where band2 is located according to the quality of the second target beam information of the second object indicated by the network when transmitting the channel.
[0141] Through the technical solution provided by the embodiments of the present application, after the terminal measures the first to-be-measured RS resources corresponding to the first object and reports the beam report, it can send the SRS corresponding to the second object, so that the network-side device measures the SRS, and further according to the measurement result of the SRS and the beam report of the first object reported by the terminal, sends a beam indication signaling for determining the first target beam information of the first object and the second target beam information of the second object to the terminal, so that the beam links between the terminal and the network-side device on the first object and the second object can be aligned, avoiding the problem that the beam links between the network and the UE are misaligned due to beam squint.
[0142] Figure 3 Another flowchart showing a method for determining beam information provided by an embodiment of the present application. This method 300 can be executed by a network-side device. In other words, the method can be executed by software or hardware installed on the network-side device. As Figure 3 shown, the method may include the following steps.
[0143] S310, the network-side device sends configuration information to the terminal, where the configuration information configures at least one first RS resource to be measured for a first object.
[0144] Method 300 is an embodiment of the network-side device corresponding to method 200 and has an implementation corresponding to method 200. In the embodiments of the present application, only some of the implementation manners will be described, and for other matters not covered, reference may be made to the description in the above method 200.
[0145] S312, the network-side device receives the beam report reported by the terminal, where the beam report carries the first beam information of the first object.
[0146] Among them, this beam report is the same as the beam report in the above method 200, and specifically, reference may be made to the description in method 200.
[0147] S314, the network-side device measures the SRS sent by the terminal on a second object.
[0148] S316, the network-side device sends a first target beam indication signaling to the terminal based on the beam report and the result obtained by measuring the SRS, where the first target beam indication signaling is used to enable the terminal to determine the first target beam information on the first object and the second target beam information on the second object.
[0149] Through the technical solution provided by the embodiments of the present application, the network-side device can, according to the beam report reported by the terminal after measuring the first RS resource to be measured corresponding to the first object, and by measuring the SRS sent by the terminal on the second object, send a beam indication signaling for determining the first target beam information of the first object and the second target beam information of the second object to the terminal, so that the beam links between the terminal and the network-side device on the first object and the second object can be aligned, avoiding the problem that the beam links between the network and the UE are misaligned due to beam squint.
[0150] In a possible implementation, the network-side device sends a first target beam indication signaling to the terminal based on the beam report and the result obtained by measuring the SRS, which may include: the network-side device determines the first target beam information used by the terminal on the first object based on at least one of the beam report and the result obtained by measuring the SRS; and / or, the network-side device determines the first target beam information used by the terminal on the first object and the second target beam information used by the terminal on the second object based on the beam report and the result obtained by measuring the SRS.
[0151] For example, the network-side device may determine the first target beam information on the first object according to the L1-RSRP values of each first RS resource to be measured in the beam report, and determine the second target beam information on the second object according to the result obtained by measuring the SRS. Alternatively, the first target beam information on the first object and the second target beam information on the second object may also be determined by combining the beam report and the result obtained by measuring the SRS.
[0152] For example, the UE measures the CSI-RS resources in a CSI-RS resource set on band1. According to the measurement results, the UE selects 2 CSI-RS resources with better quality and reports CRI1 and CRI2 (CSI-RS resource indicator) and the L1-RSRP of each CRI in the beam report. The corresponding ones of CRI1 and CRI2 are the UE Rx beam1 and Rx beam2. The one with the best signal quality is CRI1, corresponding to the UE's DLRx beam1. The network-side device uses multiple UL Rx beams to receive and measure the SRS resources on the second object. Among them, the UE uses UL Tx beam1 to send the SRS. The network-side device determines the optimal UL Rx beam as UL Rx beam2 according to the measurement results. Then the network-side device may determine that the sourceRS in the first target beam information of the first object is CSI-RS resource1, the corresponding one on the UE side is UE Rx beam1, the corresponding one on the network-side device is DLTx beam1, and the second target beam information is UL Tx beam1 used by the UE to send the SRS, or the DLRx beam2 corresponding to UL Rx beam2, and the DLTx beam2 corresponding to UL Rx beam2 on the network-side device.
[0153] In a possible implementation, when the network-side device measures the SRS sent by the terminal on the second object, on each SRS resource configured for the second object, the network-side device may receive and measure the SRS using a first receiving beam. For example, the network-side device uses 1 UL Rx beam to receive and measure the SRS resources on the second object, determines the better SRS resources, and can determine the second target beam information on the second object according to the beam information of the SRS resources. For example, the beam information of the SRS resources is the second target beam information on the second object.
[0154] Alternatively, in another possible implementation, on each SRS resource configured for the second object, the network-side device may also separately use multiple second receiving beams to receive and measure the SRS. For example, the network uses multiple UL Rx beams to receive and measure the SRS resources on the second object, and determines the better UL Rx beam according to the measurement results, and then can determine the DL Tx beam on the second object. At this time, the Rx beam of the second target beam information on the second object at the UE side may be the same as the Rx beam of the first target beam information at the UE side.
[0155] In a possible implementation, the first target beam indication signaling may be beam indication signaling or beam activation signaling, that is, the first target beam indication signaling is used to indicate or activate the first target beam information on the first object and the second target beam information on the second object.
[0156] In a possible implementation, the first target beam information is carried in the first beam indication signaling. In this possible implementation, after receiving the first target beam indication signaling, the terminal may determine the second target beam information according to the first target beam information. For the specific method, reference may be made to the relevant description in the above method 200.
[0157] Alternatively, in another possible implementation, the second target beam information is carried in the first beam indication signaling. In this possible implementation, after receiving the first target beam indication signaling, the terminal may determine the first target beam information according to the second target beam information. For the specific method, reference may be made to the relevant description in the above method 200.
[0158] In another possible implementation, both the first target beam information and the second target beam information are carried in the first target beam indication signaling. The terminal determines the first target beam information of the first object and the second target beam information of the second object according to the first target beam information and the second target beam information carried in the first target beam indication signaling.
[0159] In the above possible implementation manners, the first target beam information is one of the first beam pools configured by the network-side device for the first object; the second target beam information on the second object is one of the first beam pools, or the second target beam information on the second object is one of the second beam pools configured by the network-side device for the second object.
[0160] In the above possible implementation manners, the first target beam information may include the identification information of the first target beam, for example, ID or number, etc., such as, TCIstateID. The second target beam information may include the identification information of the second target beam, for example, ID or number, etc. Such as, TCIstateID.
[0161] In a possible implementation manner, after the network-side device receives the beam report reported by the terminal, the method further includes: the network-side device updates the beam information of the first target object or updates the to-be-measured RS resource of the first target object, where the first target object includes at least one of the first object and the second object.
[0162] The network-side device and the terminal can respectively automatically update the beam information of the first target object or the to-be-measured RS resource of the first target object. For example, the network-side device can update the beam information of the first object or the first to-be-measured RS resource of the first object according to the first beam information of the first object included in the beam report sent by the UE; and / or, update the beam information of the second object or the second to-be-measured RS resource of the second object according to the measurement of the SRS on the second object.
[0163] Optionally, the network-side device can also instruct the terminal to perform the update. Therefore, after the network-side device updates the beam information of the first target object or updates the to-be-measured RS resource of the first target object, the method further includes: the network-side device sends a second target beam indication signaling to the terminal, where the second target beam indication signaling instructs to update the beam information of the first target object or update the to-be-measured RS resource of the first target object.
[0164] In the above possible implementation manners, optionally, the second target beam indication signaling instructing to update the beam information of the first target object or update the to-be-measured RS resource of the first target object includes one of the following:
[0165] The second target beam indication information carries the first target beam information, instructing the terminal to update the beam information of the first object to the first target beam information, or update the first to-be-measured RS resource of the first object to the RS resource corresponding to the first target beam information;
[0166] The second target beam indication information carries the first target beam information, and instructs the terminal to update the beam information of the first object to the first target beam information, or update the first to-be-measured RS resource of the first object to the RS resource corresponding to the first target beam information; and instructs the terminal to update the beam information of the second object to the second target beam information corresponding to the first target beam information, or update the second to-be-measured RS resource of the second object to the RS resource corresponding to the second target beam information;
[0167] The second target beam indication information carries the second target beam information, and instructs the terminal to update the beam information of the second object to the second target beam information, or update the second to-be-measured RS resource of the second object to the RS resource corresponding to the second target beam information;
[0168] The second target beam indication information carries the second target beam information, and instructs the terminal to update the beam information of the second object to the second target beam information, or update the second to-be-measured RS resource of the second object to the RS resource corresponding to the second target beam information; and instructs the terminal to update the beam information of the first object to the first target beam information corresponding to the second target beam information, or update the first to-be-measured RS resource of the first object to the RS resource corresponding to the first target beam information;
[0169] The second target beam indication information carries the first target beam information of the first object and the second target beam information of the second object, and instructs the terminal to update the beam information of the first object to the first target beam information, or update the first to-be-measured RS resource of the first object to the RS resource corresponding to the first target beam information; and instructs the terminal to update the beam information of the second object to the second target beam information, or update the second to-be-measured RS resource of the second object to the RS resource corresponding to the second target beam information.
[0170] In the above possible implementation manners, optionally, the second target beam indication signaling carrying the first target beam information of the first object includes: the second target beam indication signaling carries the first common TCI state of the first member carrier group, where the first object belongs to or includes the first member carrier group.
[0171] Optionally, the second target beam indication signaling carrying the second target beam information of the second object may include: the second target beam indication signaling carries the second common TCI state of the second member carrier group, where the second object belongs to or includes the second member carrier group.
[0172] Optionally, the second target beam indication signaling carries first target beam information of the first object and second target beam information of the second object, including: the second target beam indication signaling carries a first common TCI state of a first member carrier group and a second common TCI state of a second member carrier group, where the first object belongs to or includes the first member carrier group, and the second object belongs to or includes the second member carrier group.
[0173] In a possible implementation, the second target beam indication signaling indicating to update the beam information of the first target object or the measured RS resource to be measured of the first target object includes at least one of the following:
[0174] The second target beam indication signaling indicates that a first transmission configuration indication (TCI) state of the first target object is updated to a target TCI state;
[0175] The second target beam indication signaling indicates that an RS resource of QCL type D in the first TCI state of the first target object is updated to a first target RS resource;
[0176] Wherein, the first TCI state is the TCI state of the first target object indicated by the network side device in the most recent indication, that is, the currently used TCI state, or the first TCI state is the TCI state of the first target object activated by the network side device in the most recent activation, that is, the TCI state in the currently activated state.
[0177] In this possible implementation, the network side device may update the RS resource of QCL type D (QCL-TypeD) in the first TCI state to the first target RS resource through the second target beam indication signaling. For example, the network side device updates the QCL-TypeD source RS resource in the first TCI state through a MAC CE command. The first TCI state may be the TCI state indicated by the network side device in the beam indication signaling most recently, or the TCI state activated by the network side device most recently, or the network side device indicates the updated TCI state to the UE using the beam indication signaling or the activation command.
[0178] For example, if the first target beam information of the first object is carried in the second target beam indication signaling, the RS resource of QCL-TypeD indicating the first TCI state of the first object is updated to the RS resource corresponding to the first target beam information. If the second target beam information of the second object is carried in the second target beam indication signaling, the RS resource of QCL-TypeD indicating the first TCI state of the second object is updated to the RS resource corresponding to the second target beam information. If the first target beam information of the first object and the second target beam information of the second object are carried in the second target beam indication signaling, the RS resource of QCL-TypeD indicating the first TCI state of the first object is updated to the RS resource corresponding to the first target beam information, and the RS resource of QCL-TypeD indicating the first TCI state of the second object is updated to the RS resource corresponding to the second target beam information.
[0179] In a possible implementation, the method may further include: when the first object belongs to or includes a first component carrier group, the network side device updates the beam information of each component carrier in the first component carrier group based on the updated first target beam information of the first object; and / or when the second object belongs to or includes a second component carrier group, the network side device updates the beam information of each component carrier in the second component carrier group based on the updated second target beam information of the second object.
[0180] In the embodiments of the present application, for the CA scenario, the network side device may configure at least one set of component carriers (CCs), and each set of CCs may correspond to different objects, for example, different bands. The target beam information (the first target beam information or the second target beam information) indicated by the second target beam indication signaling is used to update the beam information of all CCs and all BWPs in a set of CCs simultaneously. Alternatively, multiple sets of CCs may be associated. For example, if an object includes multiple sets of CCs, the target beam information (the first target beam information or the second target beam information) indicated by the second target beam indication signaling is used to determine the beam information or RS resources of each set of CCs in the object, for example, QCL-TypeD RS resources, that is, the QCL-TypeD RS resources between sets are different, and the QCL-TypeD RS resources of each CC within a set may be the same RS resource or different RS resources.
[0181] When the number M of downlink (DL) TCI states configured by the network - side device is greater than 1 and / or the number N of uplink (UL) TCI states is greater than 1, the second target beam indication signaling can indicate TCI states of different objects, where each TCI state is used to determine the beam information of multiple channels or RSs on at least one CC for each object.
[0182] In each of the above - mentioned possible implementation manners, the first object and the second object each include at least one of the following:
[0183] Cell;
[0184] Bandwidth Part (BWP);
[0185] Sub - band;

[0195] (5) Activating or using the first object when the signal quality of the first beam information meets a second preset condition. It should be noted that when the network - side device activates or uses a first object, it means notifying the UE to activate or use a certain object through network signaling, rather than the network - side device itself activating or using a certain object.
[0196] In the case where the signal quality of the first beam information does not meet the second preset condition, deactivate or do not use the first object;
[0197] (7) In the case where the performance of using the first target beam information to transmit a channel or a reference signal meets the third preset condition, activate or use the first object;

[0199] (9) In the case where the performance of using the first target beam information to transmit a channel or a reference signal does not meet the third preset condition, deactivate or do not use the first object;
[0200] (10) Receive an eighth notification sent by the terminal, where the eighth notification indicates that the performance of the terminal using the first target beam information to transmit a channel or a reference signal does not meet the third preset condition;
[0201] (11) Send a first signaling to the terminal, where the first signaling indicates to activate or use the first object; for example, the network-side device may determine to activate or use the first object according to the beam report reported by the terminal and / or the above at least one notification. For example, when the first beam information in the beam report meets the preset condition, such as at least one L1-RSRP in the beam report reaches the preset first threshold, activate or use the first object. Or, activate or use the first object when the first beam information of the first object is included in the beam report reported by the terminal, without judging the condition.
[0202] (12) Send a second signaling to the terminal, where the second signaling indicates to deactivate or not use the first object. For example, the network-side device may determine to deactivate or not use the first object according to the beam report reported by the terminal and / or the above at least one notification. For example, when the first beam information in the beam report does not meet the preset condition, such as any one of the L1-RSRPs in the beam report does not reach the preset first threshold, deactivate or do not use the first object.
[0203] In a possible implementation manner, the method further includes at least one of the following:
[0204] (1) Receive a ninth notification sent by the terminal, where the ninth notification indicates that the second object is in an active state or a used state;
[0205] (2) Receive an eleventh notification sent by the terminal, where the eleventh notification indicates that the second object is in a deactivated state or a non-used state;

[0210] (7) When the result obtained by measuring the SRS meets a fifth preset condition, activate or use the second object;
[0211] For example, the network side device may activate or use the second object when the L1-RSRP of the SRS reaches a preset threshold.
[0212] (8) When the result obtained by measuring the SRS does not meet the fifth preset condition, deactivate or do not use the second object;
[0213] (9) Send a third signaling to the terminal, where the third signaling indicates to activate or use the second object;
[0214] (10) Send a fourth signaling to the terminal, where the fourth signaling indicates to deactivate or do not use the second object.
[0215] For example, the first object is band1 and panel1, and the second object is band2 and panel2, that is, the two panels of the UE support different bands respectively. The UE uses panel1 to measure the CSI-RS resources on band1 and uses panel2 to send SRS on the SRS resources on band2. The UE reports the measurement results in the beam report, that is, the CRI and L1-RSRP corresponding to band1. The network side device can determine whether to activate or use the panel where each band is located according to the L1-RSRP value corresponding to band1 and the L1-RSRP value of the SRS on band2. The network side device sends a signaling to the UE to notify the UE to activate or use the corresponding band and panel to receive and transmit a channel or a reference signal.
