Description

Method for determining beam information, terminal and network side equipment

Technical Field

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

Background

When the bandwidth of one frequency band is large, a beam squint phenomenon may occur due to a difference in signal propagation characteristics at different frequency positions. For example, a large bandwidth frequency band edge frequency point and a large bandwidth frequency band center frequency point have a deviation in a beam direction, and when a network performs beam training according to the center frequency point and selects an optimal beam, the optimal beam is used to transmit a channel in a full bandwidth, and the beam direction at the edge frequency point will have a deviation, so that the quality of a beam link will also deteriorate.

The concepts of Independent Beam Management (IBM) and Common Beam Management (CBM) were introduced in the Third Generation Partnership Project (3 GPP) to describe two different modes of operation under inter-band Carrier Aggregation (CA) for Frequency Range (FR) 2.

The IBM refers to User Equipment (UE) that can independently select an optimal beam through independent beam management, where a Primary Component Carrier (PCC) and a Secondary Component Carrier (SCC) can independently select the optimal beam. In this case, different CCs may have relatively optimal transceiving performance, but the disadvantage is that signaling overhead is large and the architecture design of the UE is more complicated.

The CBM means that the UE performs a beam management process only by the PCC, and the SCC directly applies the configuration of the PCC. The method has the advantages of saving signaling overhead, simplifying the UE structure and reducing the cost. However, since FR2 employs hybrid beamforming, in this configuration, the beams of the PCC and the SCC are configured by using the same phase shifter, which may cause the beam pointing direction of the SCC to be deviated from the PCC to a certain degree, resulting in so-called "beam squint" and performance degradation.

As can be seen, the beam squint phenomenon may cause the performance of a beam link to be degraded when the bandwidth is large or the frequency band is crossed, and therefore, if the beam management result of the PCC is directly applied to the SCC, the beam link between the network and the UE may be misaligned on the SCC, resulting in poor performance.

In other words, the method may be performed by software or hardware installed on the terminal. As shown in fig. 2, the method may include the following steps.

S210, the terminal measures the signal quality of at least one first Reference Signal (RS) resource to be measured according to the received configuration information, wherein the first RS resource to be measured corresponds to a first object.

In the related art, when performing beam measurement, a network side device configures configuration information of a beam report for a terminal, where the configuration information is associated with reference Signal resource setting (RS resource setting), where 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 (resource) or a Channel State information reference Signal (CSI-RS) resource. The terminal measures the layer 1 Reference Signal Received Power (RSRP) and/or the layer 1 Signal-to-noise and Interference plus noise Ratio (SINR) of each RS Resource, and reports at least one optimal measurement result to the network, wherein the report content comprises SSB Resource Indicator (SSBRI) or CSI-RS Resource Indicator (CRI), and L1-RSRP and/or L1-SINR. In addition, in the configuration information of the beam report, it may be indicated whether the report is a packet-based beam report. If not, the UE will report at least one optimal beam and its quality for the network side to determine the beam to use to send channels or signals to the UE. If it is a packet-based beam report (packet-based beam report), the UE will report a pair of beams and their quality, and when the network side uses the pair of beams to send information to the UE, the UE can receive at the same time.

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

The first RS resource to be measured corresponding to the first object may include one of the following:

(1) A first RS resource to be measured in a first RS resource set (resource set) to be measured corresponding to a first object;

(2) A first RS resource to be measured in a first RS resource setting (resource configuration or resource setting) to be measured corresponding to the first object;

(3) And a first RS resource to be measured in the first RS resource group to be measured corresponding to the first object.

The corresponding relation between the first object and the first to-be-measured RS resource can be determined in the following way:

(1) Adding a number or an ID of a first object to the first RS resource to be measured, the first RS resource to be measured setting, the first RS resource set to be measured (set), or the first RS resource group to be measured, for example, adding a number or an ID of a first object to the reference signal resource setting (setting), or the RS resource set included in the RS resource setting, or the RS resource in the RS resource set, or the description information of the RS resource group includes a number or an ID of a first object, and using the RS resource setting, the RS resource set, the RS resource group, or the RS resource group to correspond to the first object;

(2) Configuring a first RS resource to be measured, a first RS resource to be measured setting, a first RS resource set (set) to be measured or a first RS resource group to be measured in the configuration information of the first object; that is, the first RS resource to be measured corresponding to the first object is configured in the configuration information of the first object, where the configuration information may be one or more RS resources, or may be one RS resource setting, that is, all RS resources in the RS resource setting are indicated to correspond to the first object, or may also be one or more RS resource sets or RS resource groups.

(3) The configuration information of the CSI report includes the first RS resource to be measured, the setting of the first RS resource to be measured, the set (set) of the first RS resource to be measured, or the association or mapping relationship between the first RS resource group to be measured and the number or ID of the first object.

(4) The network side device indicates, through signaling, an association or mapping relationship between the first RS resource to be measured, the first RS resource to be measured setting, the first RS resource set to be measured (set), or the number or ID of the first RS resource set to be measured and the first object, for example, the network side device indicates the association or mapping relationship through a Medium Access Control (MAC) Control Element (CE) or DCI.

Wherein the first object includes, but is not limited to, one of: (1) a cell (cell); (2) Bandwidth Part (BWP); (3) sub-band; (4) frequency band (band); (5) Transmitting a Reception Point (TRP); (6) a terminal panel (UE panel); and (7) carrying waves.

That is, one first object may be one cell, BWP, subband, 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 the first beam information of the first object.

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

S214, the terminal transmits an SRS corresponding to the second object.

In this embodiment of the application, the terminal transmits an SRS corresponding to the second object, so that the network side device may measure the SRS to determine target beam information on the second object.

In the embodiment of the present application, corresponding to the first object, the second object may include, but is not limited to, one of the following: (1) a cell (cell); (2) Bandwidth Part (BWP); (3) sub-band (sub-band); (4) frequency band (band); (5) Transmitting a Reception Point (TRP); (6) a terminal panel (UE panel); and (7) carrying waves.

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

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

In one possible implementation manner, the terminal may determine 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 transmit the SRS on the second object using the second beam information.

For example, after the terminal measures each CSI-RS resource in the CSI-RS resources on band1, and then includes CRI1, that is, the measurement result of CSI-RS resource1 in the sent beam report, the second beam information used for sending the SRS on band2 may be determined according to the beam information of CSI-RS resource 1. The Rx beam when measuring the CSI-RS resource1 and the Tx beam used for transmitting the SRS on the band2 may have beam consistency (i.e. the direction of the Rx beam is the direction of the Tx beam), for example, the Rx beam of the CSI-RS resource1 is used as the Tx beam for transmitting the SRS on the band2, or the Rx beam of the CSI-RS resource1 is adjusted to determine the Tx beam for transmitting the SRS on the band2 according to the Rx beam of the CSI-RS resource1 without beam consistency, for example, the beam in the direction adjacent to the Rx beam of the CSI-RS resource1 is used as the Tx beam for transmitting the SRS on the band 2.

In another possible implementation manner, the terminal may also determine, according to the first target beam information, second beam information used for transmitting the SRS on the second object. For example, after receiving the beam report reported by the terminal, the network side device may select one piece of first beam information from the beam report as the first target beam information to indicate to the terminal, and the terminal may determine, according to the first target beam information indicated by the network side device, the second beam information used for transmitting the SRS on the second object. For example, the beam report of the band1 includes CRI1 and CRI2, that is, measurement results of the CSI-RS resource1 and the CSI-RS resource2, and 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 sending the SRS on the band2 according to the beam information of the CSI-RS resource1, for example, the Rx beam of the CSI-RS resource1 is used as the Tx beam used for sending the SRS on the band2, or the Rx beam of the CSI-RS resource1 is adjusted according to the Rx beam of the CSI-RS resource1 to determine the Tx beam of the SRS on the band2, for example, the beam in the direction adjacent to the beam of the CSI-RS resource1 is used as the Tx beam of the SRS on the band 2.

In yet another possible implementation manner, the network side device may indicate, in the configured SRS resource information, beam information of an SRS resource therein, that is, beam information indicating an SRS resource on the second object, and the terminal transmits the SRS on the second object using the beam information. For example, after receiving the beam report reported by the terminal, the network side device may indicate, for the terminal, beam information of an SRS resource of a second object according to first beam information in the beam report. For example, CRI1, that is, the measurement result of CSI-RS resource1 is included in the beam report of band1, the network side device indicates beam information for the SRS resource of band2 according to the measurement result, if the UE uses Rxbeam when receiving CSI-RS resource1, the UE may determine Txbeam of the SRS resource according to the beam information indicated by the network side device for the SRS resource on band2, where the Txbeam may have beam consistency with the Rxbeam of CSI-RS resource1, or the Tx beam is located in the direction adjacent to the Rxbeam of CSI-RS resource 1. In the above possible implementation manner, when the terminal transmits the SRS on the second object, optionally, the terminal may transmit the SRS on a plurality of SRS resources by using the second beam information. Optionally, the second beam information may include a plurality of beam information, and the beam information used for transmitting the 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 beam information used for transmitting the SRS on the 3 SRS resources by the terminal may be completely different, or the terminal may transmit the SRS on 2 of the SRS resources using the same beam information and transmit the SRS on another SRS resource using another beam information, or may transmit the SRS on 3 SRS resources using the same beam information.

In another possible implementation manner, the terminal may also determine fourth beam information used for transmitting the SRS on the second object according to the third beam information of the first SRS resource corresponding to the first object, and then transmit the SRS on the second object by using the fourth beam information.

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

(1) Determined from the first beam information.

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

For example, after the terminal measures each CSI-RS resource in the CSI-RS resources on band1, and then includes CRI1, that is, the measurement result of CSI-RS resource1 in the sent beam report, first determine the first SRS resource on band1, where the beam information (that is, the third beam information) of the first SRS resource is determined according to the beam information of CSI-RS resource1, for example, rx beam of CSI-RS resource1 is used as Tx beam of the first SRS resource, or CSI-RS resource1 is used as source (source) RS of the beam information of the first SRS resource. Then, the beam information used for transmitting the SRS on the 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 of the SRS transmitted on the band2, or the Tx beam of the SRS transmitted on the band2 is determined by adjusting the Tx beam of the first SRS resource, for example, the beam in the direction adjacent to the Tx beam of the first SRS resource is used as the Tx beam of the SRS transmitted on the band 2.

(2) And determining 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 piece of first beam information from the beam report as the first target beam information to indicate to the terminal, and the terminal may determine, according to the first target beam information indicated by the network side device, third beam information of the first SRS resource, and then determine, according to the third beam information, fourth beam information used for sending the SRS on the second object. For example, the beam report of the band1 includes CRI1 and CRI2, that is, measurement results of the CSI-RS resource1 and the CSI-RS resource2, and a source RS in the first target beam information indicated by the network side device is CSI-RS resource1, the terminal determines the first SRS resource on the band1 according to the CSI-RS resource1, for example, the terminal uses an Rx beam of the CSI-RS resource1 as a Tx beam (i.e., third beam information) of the first SRS resource, or uses the CSI-RS resource1 as a source (source) RS of the beam information of the first SRS resource. And then determines beam information used for transmitting the SRS on the band2 according to the beam information of the first SRS resource.

(3) And determining according to the beam information of the first SRS resource indicated by the network side equipment.

And the terminal takes the beam information of the first SRS resource indicated by the network side equipment as the third beam information, and determines fourth beam information used for transmitting the SRS on the second object according to the third beam information. For example, the network side device may indicate beam information of the first SRS resource in 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 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.

Alternatively, the terminal may determine the first beam information used for transmitting the SRS on the second object by combining two or three of the three items. Details are not repeated.

In each of the foregoing possible implementation manners, optionally, before the terminal transmits the SRS corresponding to the second object, the method may further include: the terminal sends a notification message, wherein the notification message indicates that the terminal currently uses the CBM mode; and/or the terminal receives first indication information of the network side equipment, wherein the first indication information indicates that the terminal uses a CBM mode.

S216, the terminal receives a 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 may determine beam information of the network side device on the second object, so that the terminal may be indicated through the first target beam indication signaling.

S218, the terminal determines first target beam information of the first object and second target beam information of the second object according to the first target beam indication signaling.

According to the technical scheme provided by the embodiment of the application, after the terminal measures the first to-be-measured RS resource corresponding to the first object and reports the beam report, the terminal can send the SRS corresponding to the second object, so that the network side equipment 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 result of measuring the SRS and the beam report of the first object reported by the terminal, so that the beam links of the terminal and the network side equipment on the first object and the second object can be aligned, especially for a CBM mode terminal, the problem of so-called beam squint caused by that the beam direction of the SCC has a certain deviation relative to the PCC can be avoided, and the communication performance is improved.

In a possible implementation manner of the embodiment of the present application, the first target beam instruction may carry first target beam information of a first object but not carry second target beam information of a second object, 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, and then the terminal may determine, according to the first target beam information, second target beam information of the second object.

Optionally, the determining, by the terminal, second target beam information of the second object according to the first target beam information includes: the terminal acquires third target beam information corresponding to the first target beam information, wherein the third target beam information is beam information used for transmitting the SRS determined according to the first target beam information; and the terminal determines the second target beam information according to the third target beam information.

That is, 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 transmitting the SRS in S214. For example, the beam information used by the terminal to transmit the SRS is the second beam information obtained from the first beam information on the first object or the fourth beam information obtained from 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 first target beam information, where 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. The second target beam information on the second object may be determined according to one of second beam information or fourth beam information used when the SRS is transmitted, where the one of the second beam information or the fourth beam information is the same as the one of the first beam information, that is, the beam information used for transmitting the SRS is determined according to the one of the first beam information.

For example, the terminal includes CSI-RS resource1 and CSI-RS resource2 in the beam report of band1, the sourceRS in the TCIstate carried in the first target beam indication instruction sent by the network-side device is CSI-RSresource1, the terminal receives Rxbeam1 used by CSI-RS resource1, and if the terminal sends SRS of the second object, rx beam1 of CSI-RS resource1 is used as Tx beam1 of SRS resource of the second object, or Txbeam2 of the first srsrsresource is determined according to Rxbeam1, and Txbeam1 of the second object is determined according to Txbeam2, then the terminal may determine the second target beam information of the second object according to the beam information (i.e. third target beam information) used for sending SRS. For example, the second target beam information may be determined to be third target beam information, or the beam information obtained after the third target beam information is adjusted.

For another example, if the second beam information used for transmitting 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 transmitting the SRS, for example, the second target beam information is determined to be the second beam information used for transmitting the SRS, or the beam information obtained by performing a certain adjustment on the second beam information used for transmitting the SRS.

In another possible implementation manner, the first target beam instruction may carry second target beam information of a second object but not carry first target beam information of a first object, in which case, the terminal determines that the target beam information of the second object is the second target beam information carried by the first target beam indication signaling, and then, the terminal may determine the first target beam information of the first object according to the second target beam information.

For example, the terminal includes CSI-RS resource1 in the beam report of band1, the terminal receives the CSI-RS resource1 using Rxbeam1, and if the terminal determines the Tx beam1 of the SRS resource of the second object according to the Rx beam1 of the CSI-RS resource1 when transmitting the SRS of the second object, or determines the Txbeam2 of the first sresource according to Rxbeam1, and then determines the Txbeam1 of the SRS resource of the second object according to Txbeam2, where Txbeam1 may be a plurality of beams adjacent to the direction of Rxbeam1 or Txbeam2, the network side device measures the second object on the plurality of beams and then obtains the optimal beam information of the SRS of the second object, and the network side device adjusts the second target beam information according to the second target beam information when indicating the second target beam information using the second target beam indication command, and then obtains the optimal beam information of the SRS resource of the second target beam according to the second target beam information (for example, the optimal beam information of the second target beam information is determined by the terminal), and then obtains the optimal beam information of the second target beam information, such as the second target beam information of the second target beam information, or the optimal beam information of the second target beam information, such as the second target beam information of the second target beam information, which is determined by the terminal.

In yet another possible implementation manner, the first target beam instruction may carry first target beam information of a first object and second target beam information of a second object, and the terminal determines that 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 an identifier of a first object and the first target beam information, and an identifier of a second object and the second target beam information.

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

In the above possible implementation manner, the first target beam information may include identification information of the first target beam, for example, an ID or a number, such as a TCI state ID; the second target beam information may include identification information of the second target beam, for example, an ID or number, etc., such as a TCI state ID.

In this embodiment, the first target beam indication signaling may be used to indicate or activate first target beam information of a first object and second target beam information of a second object, for example, to instruct a terminal to communicate with a network-side device on the first object using the first target beam information, and communicate with the network-side device on the second object using the second target beam information.

In one possible implementation, after the terminal reports the beam report, the method may further include the following steps: the terminal updates beam information of the first target object or updates RS resources to be measured of the first target object, wherein the first target object comprises: at least one of the first object and the second object.

For example, the terminal may update beam information of the first object or RS resources to be measured of the first object according to first beam information of the first object, and/or update beam information of the second object or RS resources to be measured of the second object according to second beam information used for transmitting an SRS on the second object.

Optionally, before the terminal updates the beam information of the first target object or updates the RS to be measured resource of the first target object, the method further includes: and the terminal receives a second target beam indication signaling sent by network side equipment, wherein the second target beam indication signaling indicates to update beam information of a first target object or update RS resources to be measured of the first target object.

That is, in the above possible implementation manners, the network side device may instruct to update the beam information of the first object and/or the second object, or update the RS resources to be measured of the first object and/or the second object. For example, the configuring, by the network side device, the first RS resource to be measured corresponding to the first object includes: the terminal measures a first RS resource to be measured, selects 2 CSI-RS resources with better quality according to measurement results, reports CRI1 and CRI2 in a beam report, and corresponds to CRI1 and CRI2 UE Rx beam1 and Rx beam2, the network side equipment sends a second target beam indication signaling according to the beam report, the second target beam indication signaling carries first target beam information of a first object, for example, the first target beam information is TCI state1, the source RS of TCI state1 is CSI-RS resource1, namely the terminal updates the first target beam information of the first object to TCI state1, the terminal uses the source (Rx beam 1) of the source RS (CSI-RS 1) to transmit a channel with the network, and only needs to perform measurement on the first target beam information, namely, the terminal can save the measurement channel, and the measurement can only need to perform measurement on the first target RS resource according to the measurement result, and the measurement result is that the next measurement is the next measurement on the first target RS resource, namely, the terminal can save the measurement on the TCI-RS resource, and the measurement result is that the measurement on the next measurement on the CSI-RS resource.

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

In a possible implementation manner, the second target beam indication signaling may carry first target beam information of the first object but not carry second target beam information of a second object, and in this case, the terminal may update the beam information of the first object to the first target beam information or update the first RS resource to be measured of the first object to an RS resource corresponding to the first target beam information. Or, the terminal may update the beam information of the first object to the first target beam information or update the first RS resource to be measured of the first object to an 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 RS resource to be measured of the second object to an 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 beam information used for transmitting the SRS determined according to the first target beam information. Or, a preset corresponding relationship exists between the first target beam information and the second target beam information, where the corresponding relationship may be indicated by the network side device, or may also be agreed by a protocol, for example, the agreement is agreed by the protocol or the network side device configures 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.

In another possible implementation manner, the second target beam indication signaling may also carry second target beam information of the second object but not carry first target beam information of the first object, and in this case, the terminal may update the beam information of the second object to the second target beam information or update the second RS resource to be measured of the second object to an RS resource corresponding to the second target beam information. Or, the terminal may update the beam information of the second object to the second target beam information or update the second RS resource to be measured of the second object to an RS resource corresponding to the second target beam information, determine the first target beam information of the first object according to the second target beam information, update the beam information of the first object to the first target beam information or update the first RS resource to be measured of the first object to an 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, or a preset correspondence exists between the first target beam information and the second target beam information, where the correspondence may be indicated by the network side device, or may also be agreed by a protocol, for example, the agreed protocol or offset information between the first target beam information and the second target beam information configured by the network side device, and the terminal may determine the corresponding first target beam information according to the second target beam information.

In yet another possible implementation manner, the second target beam indication signaling may carry first target beam information of the first object and second target beam information of the second object, and in this case, the terminal may 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 an RS resource corresponding to the first target beam information according to an indication of the second target beam indication signaling; and updating the beam information of the second object to the second target beam information or updating the second RS resource to be measured of the second object to the RS resource corresponding to the second target beam information. For example, the second target beam indication signaling may carry a corresponding relationship between the identification information of the first target beam and the identification information of the first object, and a corresponding relationship between the identification information of the second target beam and the identification information of the second object. Or, the second target beam indication signaling may also 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 according to a preset sequence or a preset position according to a protocol convention or a configuration of a 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.

In a possible implementation manner, the step of the second target beam indication signaling carrying the first target beam information of the first object may include: the second target beam indication signaling carries a first common TCI state for a first component carrier group, wherein the first object belongs to or includes the first component carrier group.

The second target beam indication signaling carrying second target beam information of the second object may include: the second target beam indicates a second common TCI state signaling carrying a second group of component carriers, wherein the second object belongs to or includes the second group of component carriers.

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 component carrier group and a second common TCI state of a second component carrier group, wherein the first object belongs to or includes the first component carrier group, and the second object belongs to or includes the second component carrier group.

In one possible implementation, the second target beam indication signaling to update the beam information of the first target object or to update the RS resource to be measured of the first target object includes at least one of:

(1) The second target beam indication signaling indicates that the first transmission configuration of the first target object indicates that the TCI status is updated to the target TCI status. The first TCI state is a TCI state of the first target object indicated by the network-side device last time, that is, a currently used TCI state, or the first TCI state is a TCI state of the first target object activated by the network-side device last time, that is, a currently activated TCI state.

In this possible implementation manner, the network side device may carry the identifier of the target TCI state in the second target beam indication signaling.

(2) The second target beam indication signaling indicates that the RS resource of QCL type D in the first TCI state of the first target object is updated to the first target RS resource.

In this possible implementation manner, the network side device may update, through the second target beam indication signaling, the RS resource of QCL type D (QCL-type) in the first TCI state to be the first target RS resource. 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 a TCI state indicated by the network side device in the beam indication signaling last time, or a TCI state activated by the network side device last time, or a TCI state updated after the network side device indicates the UE using the beam indication signaling or the activation command.

For example, if the second target beam indication signaling carries the first target beam information of the first object, the RS resource of QCL-type indicating the first TCI state of the first object is updated to the RS resource corresponding to the first target beam information. And if the second target beam indication signaling carries second target beam information of the second object, updating the RS resource of QCL-TypeD indicating the first TCI state of the second object to the RS resource corresponding to the second target beam information. And if the second target beam indication signaling carries the first target beam information of the first object and the second target beam information of the second object, indicating that the RS resource of the 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 updating the RS resource of the QCL-TypeD in the first TCI state of the second object to the RS resource corresponding to the second target beam information.

And in the case that the second object belongs to or comprises a second component carrier group, the terminal updates the beam information of each component carrier in the second component carrier group based on the updated beam information of the second object.

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 simultaneously update the beam information of all CCs and all BWPs in a set of CCs. Alternatively, multiple sets of CCs may be associated, for example, if one 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 beam information or RS resources of each set of CCs in the object, for example, QCL-type RS resources, i.e., source (source) RS resources of QCL-type RS, that is, QCL-type RS resources between sets are different, and the QCL-type RS resources of CCs in a set may be the same RS resource or different RS resources.

In case that the number of Downlink (DL) TCI states M >1 and/or the number of Uplink (UL) TCI states N >1 configured by the network side device, the second target beam indication signaling may indicate TCI states of different objects, where each TCI state is used to determine beam information of multiple channels or RSs on at least one CC on each object.

Fig. 3 shows another flowchart of the method for determining beam information according to the embodiment of the present application, where the method 300 may be executed by a network side device. In other words, the method may be performed by software or hardware installed on the network-side device. As shown in fig. 3, the method may include the following steps.

S310, the network side equipment sends configuration information to the terminal, wherein the configuration information configures at least one first RS resource to be measured for the first object.

The method 300 is an embodiment of a network-side device corresponding to the method 200, and has an implementation manner corresponding to the method 200, in the embodiment of the present application, only a part of the implementation manners may be described, and otherwise, reference may be made to the description in the method 200.

S312, the network side device receives a beam report reported by the terminal, where the beam report carries the first beam information of the first object.

The beam report is the same as the beam report in the method 200, and specific reference may be made to the description in the method 200.

S314, the network side device measures the SRS transmitted by the terminal on the second object.

S316, the network side device sends a first target beam indication signaling to the terminal based on the beam report and a result obtained by measuring the SRS, where the first target beam indication signaling is used to enable the terminal to determine first target beam information on the first object and second target beam information on the second object.

According to the technical scheme provided by the embodiment of the application, the network side equipment can send the 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 according to the beam report reported after the terminal measures the first to-be-measured RS resource corresponding to the first object and the SRS sent by the terminal on the second object, so that beam links of the terminal and the network side equipment on the first object and the second object can be aligned, and the problem that the beam link between the network and the UE is not aligned due to beam squint is avoided.

In a possible implementation manner, the sending, by the network side device, a first target beam indication signaling to the terminal based on the beam report and the result obtained by measuring the SRS 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 a result obtained by measuring the SRS; and/or the network side device determines, based on the beam report and a result obtained by measuring the SRS, the first target beam information used by the terminal on the first object and the second target beam information used on the second object.

For example, the network side device may determine first target beam information on the first object according to the L1-RSRP value of each first RS resource to be measured in the beam report, and determine second target beam information on the second object according to a 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 be determined in combination with the beam report and the result of the measurement of the SRS.

For example, the UE measures the CSI-RS resource in one CSI-RS resource set on the band1, selects 2 CSI-RS resources with better quality according to the measurement result, and reports CRI1 and CRI2 (CSI-RS resource indicator) and the respective L1-RSRP of the two CRIs in the beam report. Corresponding to CRI1 and CRI2 are UE Rx Beam1 and Rx Beam2. The signal quality is the best CRI1, corresponding to the DLRx beam1 of the UE. And the network side equipment receives and measures the SRS resource on the second object by using a plurality of UL Rx beams, wherein the UE sends the SRS using the UL Rx beam1, and the network side equipment determines that the optimal UL Rx beam is the UL Rx beam2 according to the measurement result. The network side device may determine that the sourceRS in the first target beam information of the first object is CSI-RSresource1, the UE side corresponds to UE Rx beam1, the network side device corresponds to DLTxbeam1, the second target beam information is ULTxbeam1 used by the UE side to transmit SRS, or DL Rxbeam2 corresponding to UL Rx beam2, and the network side device corresponds to dlxbeam 2.

In a possible implementation manner, when a network side device measures an SRS transmitted by a terminal on a second object, the network side device may receive and measure the SRS using one first receiving beam on each SRS resource configured for the second object. For example, the network side device receives and measures SRS resources on the second object by using 1 UL Rx beam, determines a better SRS resource, and may determine second target beam information on the second object according to beam information of the SRS resource, where the beam information of the SRS resource is the second target beam information on the second object, for example.

Alternatively, in another possible implementation manner, on each SRS resource configured for the second object, the network side device may also use a plurality of second reception beams to receive and measure the SRS, respectively. For example, the network receives and measures SRS resources on the second object by using a plurality of UL Rx beams, and determines a better UL Rx beam according to the measurement result, and further determines DL Txbeam on the second object, where the Rx beam on the UE side of the second target beam information on the second object may be the same as the Rx beam on the UE side of the first target beam information.

In one 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 first target beam information on the first object and second target beam information on the second object.

In one possible implementation manner, the first target beam information is carried in the first beam indication signaling. In this possible implementation manner, after receiving the first target beam indication signaling, the terminal may determine the second target beam information according to the first target beam information, which may specifically refer to the related description in the method 200.

Or, in another possible implementation manner, the first beam indication signaling carries the second target beam information. In this possible implementation manner, after receiving the first target beam indication signaling, the terminal may determine the first target beam information according to the second target beam information, which may specifically refer to the related description in the method 200.

In another possible implementation manner, the first target beam indication signaling carries the first target beam information and the second target beam information. And the terminal determines first target beam information of the first object and 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.

In the foregoing possible implementation manner, the first target beam information is one of a first beam pool configured for the first object by the network side device; 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 second beam pools configured by a network side device for the second object.

In the above possible implementation manner, the first target beam information may include identification information of the first target beam, for example, an ID or a number, etc., such as TCIstateID. The second target beam information may include identification information of the second target beam, for example, an ID or a number, etc. Such as tcistatid.

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 equipment updates beam information of a first target object or updates RS resources to be measured of the first target object, wherein the first target object comprises: at least one of the first object and the second object.

The network side device and the terminal may respectively and automatically update the beam information of the first target object or the RS resource to be measured of the first target object. For example, the network side device may update the beam information of the first object or the first RS resource to be measured 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 updating beam information of the second object or a second RS resource to be measured of the second object according to the SRS on the second object.
