Method for determining beam information, terminal and network side equipment

cross reference

The present invention claims the priority of the Chinese patent application submitted to the China Patent Office on September 15, 2021, with the application number 202111083203.8, and the title of the invention is "Method for Determining Beam Information, Terminal and Network Side Equipment", and the entire content of the application is passed References are incorporated herein.

technical field

The present application belongs to the technical field of wireless communication, and specifically relates to a method for determining beam information, a terminal and a network side device.

Background technique

When the bandwidth of a frequency band is large, beam squinting may occur due to differences in signal propagation characteristics at different frequency positions. For example, there is a deviation in the beam direction between the band edge frequency point and the center frequency point of a large bandwidth. When the network performs beam training according to the center frequency point and selects the optimal beam, use the optimal beam to transmit the channel in the full bandwidth, then The beam direction at the edge frequency point will deviate, so that the quality of the beam link will also deteriorate.

In the Third Generation Partnership Project (Third Generation Partnership Project, 3GPP), the concepts of independent beam management (Independent Beam Management, IBM) and common beam management (Common Beam Management, CBM) were introduced to describe the frequency range (Frequency Range , FR) 2 inter-band (inter-band) carrier aggregation (Carrier Aggregation, CA) under two different working modes.

Among them, IBM means that the user equipment (User Equipment, UE) can independently select the optimal beam through the independent beam management of the primary carrier (Primary Component Carrier, PCC) and secondary carrier (Secondary Component Carrier, SCC). In this case, different CCs can have relatively optimal transceiving performance, but the disadvantage is that the signaling overhead is relatively large and the architecture design of the UE is also more complicated.

The CBM means that only the PCC performs the beam management process for the UE, and the SCC directly applies the configuration of the PCC. The advantage of this method is that it saves signaling overhead, simplifies UE structure and reduces cost. However, since FR2 adopts hybrid beamforming, with this configuration, the PCC and SCC beams adopt the same phase shifter configuration, which may cause the SCC beam to have a certain deflection relative to the PCC, resulting in the so-called "beam squint , performance drops.

It can be seen that the beam squint phenomenon may lead to the performance degradation of the beam link when the bandwidth is large or across frequency bands. Therefore, if the beam management results of the PCC are directly applied to the SCC, the beam link between the network and the UE on the SCC may Misalignment, poor performance.

If it is a non-group based beam report (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. When the network side uses this pair of beams to send information to the UE, the UE can receive it at the same time.

In this application, the network side device may include the first RS resource to be measured in the configuration information, and the first RS resource to be measured corresponds to the first object. For example, the configuration information received by the terminal may include CSI report configuration information, for example, CSI-ReportConfig, and the CSI report configuration information includes the first RS resource to be measured corresponding to the first object.

The association relationship or mapping relationship of numbers or identifiers (Identity, ID), for example, the network side device indicates the association relationship or mapping relationship through a medium access control layer (Medium Access Control, MAC) control element (Control Element, CE) or DCI relation.

Wherein, the first object includes but not limited to one of the following: (1) cell (cell); (2) bandwidth part (Bandwidth Part, BWP); (3) sub-band (sub-band); (4) frequency band (band ); (5) Transmission Reception Point (TRP); (6) Terminal Panel (UE panel); (7) Carrier.

That is to say, a first object may be a cell, BWP, subband, frequency band, TRP, carrier or UE panel, or a combination thereof.

S212. The terminal reports a beam report to the network side device according to the measurement result, where the beam report includes first beam information of the first object.

In this embodiment of the present application, the terminal may send a beam report according to the configuration information received above. The first beam information corresponding to the first object determined by the UE may be included in the beam report. Wherein, the first beam information may include index information of one of the at least one RS resources to be measured, for example, SSBRI or CRI, etc., and/or may also include one of the RS resources to be measured Quality information of RS resources, for example, L1-RSRP and/or L1-SINR. For example, the beam report may include a correspondence between index information of an RS resource to be measured and quality information measured on the RS resource.

S214. The terminal sends an SRS corresponding to the second object.

In this embodiment of the present 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.

In this embodiment of the application, corresponding to the first object, the second object may include but not limited to one of the following: (1) cell (cell); (2) bandwidth part (Bandwidth Part, BWP); (3) subband (sub-band); (4) frequency band (band); (5) transmission and reception point (Transmission Reception Point, TRP); (6) terminal panel (UE panel); (7) carrier.

For example, the first object may be the first cell, and the second object may be the second cell, or the first object may be the first carrier, and the second object may be the second carrier, and so on.

In a possible implementation manner, the terminal may send the SRS on the second object according to the SRS resource information configured by the network side device.

In a possible implementation, the terminal may determine the second beam information used to send the SRS on the second object according to the first beam information corresponding to the first object determined in step S212, and then use the second beam information , sending the SRS on the second object.

For example, after the terminal measures each CSI-RS resource in the CSI-RS resource on band1, and includes CRI1 in the sent beam report, that is, the measurement result of CSI-RS resource1, it can be determined according to the beam information of CSI-RS resource1 Send the second beam information used by the SRS on band2. Among them, the Rx beam when measuring CSI-RS resource1 and the Tx beam used to send SRS on band2 can have beam consistency (that is, the direction of Rx beam is the direction of Tx beam), for example, the Rx beam of CSI-RS resource1 The beam is used as the Tx beam for sending SRS on band2, or there is no beam consistency, and the Rx beam of CSI-RS resource1 is adjusted to determine the Tx beam for sending SRS on band2, such as the Rx beam of CSI-RS resource1. The beam in the adjacent direction is used as the Tx beam for sending SRS on band2.

In another possible implementation manner, the terminal may also determine the second beam information used for sending the 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 may select one of the first beam information as the first target beam information to indicate to the terminal, and the terminal may determine the first target beam information according to the first target beam information indicated by the network side device Second beam information used for sending the SRS on the second object. For example, the beam report of band1 includes CRI1 and CRI2, that is, the measurement results of CSI-RS resource1 and CSI-RS resource2, and the source RS in the first target beam information indicated by the network side device is CSI-RS resource1, then the terminal According to the beam information of CSI-RS resource1, determine the beam information used to send SRS on band2, for example, use the Rx beam of CSI-RS resource1 as the Tx beam used to send SRS on band2, or according to the Rx of CSI-RS resource1 The beam is adjusted to determine the Tx beam for sending SRS on band2, for example, the beam in the direction adjacent to the Rx beam of CSI-RS resource1 is used as the Tx beam for sending SRS on band2.

In yet another possible implementation, the network side device may indicate the beam information of the SRS resource in the configured SRS resource information, that is, indicate the beam information of the SRS resource on the second object, and the terminal uses the beam information on the second object Send SRS on. For example, after receiving the beam report reported by the terminal, the network side device may indicate to the terminal the beam information of the SRS resource of the second object according to the first beam information in the beam report. For example, the beam report of band1 includes CRI1, that is, the measurement result of CSI-RS resource1, and the network side device indicates the beam information for the SRS resource of band2 according to the measurement result. If the UE uses Rx when receiving CSI-RS resource1 beam, the UE can determine the Tx beam of the SRS resource according to the beam information indicated by the network side device for the SRS resource on band2, and the Tx beam can have beam consistency with the Rx beam of CSI-RS resource1, or the Tx beam is located in the - Rx beam adjacent direction of RS resource1. In the foregoing possible implementation manner, when the terminal sends the SRS on the second object, optionally, the SRS may be sent on multiple SRS resources by using the second beam information. Optionally, the second beam information may include multiple beam information, and the beam information used to send SRS on different SRS resources may be the same or may not be completely the same. For example, if the second object corresponds to 3 SRS resources, the terminal The beam information used to send SRS on the three SRS resources can be completely different, or the same beam information can be used to send SRS on two of the SRS resources, and the SRS can be sent on another SRS resource using another beam information, Alternatively, the same beam information may also be used on the three SRS resources to send the SRS.

In another possible implementation, the terminal may also determine the fourth beam information used to send the 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 , sending an SRS on the second object.

In the foregoing possible implementation manners, the third beam information may be determined in at least one of the following manners:

(1) Determined according to the first beam information.

The terminal may determine the third beam information of the first SRS resource according to at least one first RS resource to be measured in the beam report corresponding to the first object, and then determine the fourth beam used for sending the SRS on the second object according to the third beam information. beam information.

For example, after the terminal measures each CSI-RS resource in the CSI-RS resource on band1, and includes CRI1 in the sent beam report, that is, the measurement result of CSI-RS resource1, it first determines the first SRS resource on band1 , the beam information of the first SRS resource (that is, the third beam information) 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 the CSI -RS resource1 is used as the source (source) RS of the beam information of the first SRS resource. Then determine the beam information used to send SRS on band2 according to the beam information of the first SRS resource, for example, use the Tx beam of the first SRS resource as the Tx beam for sending SRS on band2, or, according to the Tx beam of the first SRS resource Make adjustments to determine the Tx beam for sending SRS on band2, for example, use the beam in the direction adjacent to the Tx beam of the first SRS resource as the Tx beam for sending SRS on band2.

(2) Determine according to the first target beam information.

For example, after receiving the beam report reported by the terminal, the network side device may select one of the first beam information as the first target beam information to indicate to the terminal, and the terminal may determine the first target beam information according to the first target beam information indicated by the network side device The third beam information of the first SRS resource, and then determine the fourth beam information used for sending the SRS on the second object according to the third beam information. For example, the beam report of band1 includes CRI1 and CRI2, that is, the measurement results of CSI-RS resource1 and CSI-RS resource2, and the source RS in the first target beam information indicated by the network side device is CSI-RS resource1, then the terminal First determine the first SRS resource on band1 according to CSI-RS resource1, for example, use the Rx beam of CSI-RS resource1 as the Tx beam of the first SRS resource (that is, the third beam information), or use CSI-RS resource1 as the first SRS resource A source (source) RS of the beam information of the SRS resource. Then determine the beam information used for sending the SRS on band2 according to the beam information of the first SRS resource.

(3) Determine according to the beam information of the first SRS resource indicated by the network side device.

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 used for sending 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.

For example, if the network side device indicates that the Tx beam of the first SRS resource is beam1, the terminal can determine the Tx beam used to send the SRS on the second object according to the beam information of the first SRS resource, for example, send the SRS on the second object The Tx beam used is also beam1, or, the Tx beam used for sending the SRS on the second object is beam2 obtained by adjusting beam1.

Alternatively, the terminal may also combine two or three of the above three items to determine the first beam information used for sending the SRS on the second object. No more details.

In each of the above possible implementation manners, optionally, before the terminal sends the SRS corresponding to the second object, the method may further include: the terminal sending a notification message, the notification message indicating that the terminal is currently using CBM mode; and/or, the terminal receives first indication information from the network side device, where the first indication information indicates that the terminal uses the CBM mode.

S216. The terminal receives the first target beam indication signaling sent by the network side device.

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, so as to instruct the terminal through the first target beam indication signaling.

S218, the terminal indicates the first target beam, and determines the first target beam information of the first object and the second target beam information of the second object.

Through the technical solution provided by the embodiment of this application, after the terminal measures the first RS resource to be measured 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 can monitor the The SRS is measured, and further according to the result of the SRS measurement and the beam report of the first object reported by the terminal, the first target beam information of the first object and the second target beam information of the second object are determined, so that the terminal and The beam links of the network-side equipment on the first object and the second object can be aligned, especially for CBM mode terminals, which can avoid the so-called "beam squint" due to the fact that the beam pointing of the SCC is skewed relative to the PCC. ” problems, improving communication performance.

In a possible implementation of the embodiment of the present application, the first target beam instruction may carry the first target beam information of the first object without carrying the second target beam information of the second object. In this case, the terminal determines The target beam information of the first object is the first target beam information carried in the first target beam indication signaling, and then, the terminal may determine the second target beam information of the second object according to the first target beam information. Two target beam information.

Optionally, the terminal determining the second target beam information of the second object according to the first target beam information includes: the terminal acquiring third target beam information corresponding to the first target beam information , wherein 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 according to the third target beam information information.

That is to say, the terminal may determine the second target beam information according to the first target beam information in a corresponding manner of determining the second beam information or the fourth beam information used for sending 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 receiving the beam report corresponding to the first object, the network side device indicates the first target beam information, and the first target beam information may be one of the first beam information (ie SSBRI/CRI) reported in the beam report definite. 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, wherein one of the second beam information or the fourth beam information It is the same as one of the above-mentioned first beam information, that is, it may be the beam information used for sending the SRS determined according to one of the above-mentioned first beam information.

For example, the terminal includes CSI-RS resource1 and CSI-RS resource2 in the beam report of band1, the source RS in the TCI state carried in the first target beam indication command sent by the network side device is CSI-RS resource1, and the terminal receives the CSI -RS resource1 uses Rx beam1, and if the terminal uses the Rx beam1 of CSI-RS resource1 as the Tx beam1 of the SRS resource of the second object when sending the SRS of the second object, or determines the first SRS resource according to Rx beam1 Tx beam2 of the second object, and then determine the Tx beam1 of the SRS of the second object according to the Tx beam2, then the terminal can determine the second target beam information of the second object according to the beam information used to send the SRS (ie, the third target beam information). For example, it may be determined that the second target beam information is the third target beam information, or beam information obtained after adjusting the third target beam information.

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 may be directly determined according to the second beam information used for sending the SRS, for example , determining that the second target beam information is the second beam information used for sending the SRS, or the beam information obtained by making certain adjustments to the second beam information used for sending the SRS.

In another possible implementation manner, the first target beam instruction 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 determines that the first target beam The target beam information of the second object is the second target beam information carried in the first target beam indication signaling, and then, the terminal may determine the first target beam of the first object according to the second target beam information information.

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, and if the terminal sends the SRS of the second object, it determines the second object according to the Rx beam1 of CSI-RS resource1 The Tx beam1 of the SRS resource of the second object, or determine the Tx beam2 of the first SRS resource according to Rx beam1, and then determine the Tx beam1 of the SRS of the second object according to Tx beam2, where Tx beam1 can be the same as Rx beam1 or Tx beam2 Multiple beams in adjacent directions, 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, and the network side device uses the second target beam to indicate the command When indicating the second target beam information, the second target beam information may be determined according to the optimal beam information of the SRS of the second object (such as using the QCL source RS of the SRS resource of the optimal measurement result as the source of the second target beam information RS), the terminal can determine the first target beam information according to the second target beam information, such as the second target beam information is the first target beam information, or, after adjusting the second target beam information, the obtained beam information .

In yet another possible implementation manner, 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, and the terminal determines the target beam information of the first object is the first target beam information carried in the first target beam indication signaling, and the target beam information of the second object is the second target beam information carried in 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.

In the foregoing possible implementation manner, 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 the first One of the 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. For example, the TCI state or spatial relation information that may be included in the first target beam indication signaling, the TCI state or spatial relation information is from a pool (pool) configured by the network side device, and the pool may only be configured to correspond to the first object. The second object may use the pool configured on the first object; or, the second target beam information of the second object may be the pool configured corresponding to the second object from the network side device.

For example, the first RS resource to be measured corresponding to the first object configured by the network side device includes: CSI-RS resource1, CSI-RS resource2, CSI-RS resource3 and CSI-RS resource4, and the terminal measures the first RS resource to be measured, According to the measurement results, two CSI-RS resources with better quality are selected, and CRI1 and CRI2 are reported in the beam report. The corresponding CRI1 and CRI2 are UE Rx beam1 and Rx beam2. The network side device sends the second target according to the beam report Beam indication signaling, the second target beam indication signaling carries the first target beam information of the first object, for example, the first target beam information is TCI state 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 (Rx beam1) of its source RS (CSI-RS resource1) to transmit channels with the network, and can also transmit the first target beam information according to network commands. Once the RS resource to be measured is updated to the source RS of TCI state 1, that is, CSI-RS resource1, when the terminal performs beam measurement next time, it only needs to measure the corresponding first object CSI-RS resource1, thereby saving measurement resources.

In practical applications, the second target beam indicating signaling and the above-mentioned first target beam indicating signaling may be the same signaling, that is, the beam indicating signaling is used to indicate, activate and update beam information, or they may not be the same One signaling is not specifically limited in this embodiment of the present application.
