In order to facilitate understanding by those skilled in the art, the embodiments of the present disclosure enumerate multiple implementations to clearly describe the technical solutions of the embodiments of the present disclosure. Of course, those skilled in the art can understand that the multiple embodiments provided in the embodiments of the present disclosure can be executed alone or in combination with the methods of other embodiments in the embodiments of the present disclosure. They can also be executed alone or in combination. It is then executed together with some methods in other related technologies; the embodiments of the present disclosure do not limit this.

The terminal faces the PUSCH channel of different TRPs, and the spatial characteristics of the actual channel may be very different. Therefore, based on QCL (Quasi Co-Located, quasi co-location), it is considered that the QCL-D of the PUSCH channel in different sending directions is different.

When the QCL relationship is configured as type D, the terminal can know which transmit beam the network device uses to send signals, and can then determine which receive beam to use to receive signals based on the beam pairing relationship determined by channel measurement.

Multiple antenna panels (panels) of the terminal realize simultaneous cooperative transmission in the TRP direction of multiple base stations, which can be used to increase the reliability and throughput of transmission. At the same time, it can effectively reduce the transmission delay under multiple TRPs, but the terminal is required to have simultaneous Ability to send multiple beams.

Figure 2a is a schematic diagram of MP-MTRP (Multi-panel-Multi-TRP) transmission under S-DCI (single-DCI, single downlink control information) scheduling according to an exemplary embodiment. The transmission of PUSCH can be based on A single PDCCH (Physical Downlink Control Channel, physical downlink control channel) is the multi-PANEL/TRP transmission scheduled by S-DCI. Here, multi-antenna panels and multi-transceiver point transmission based on S-DCI scheduling can send one or more layers of a codeword through different antenna panels based on different broadband precoding matrix indicators (Transmitted Precoding Matrix Indicator, TPMI). (layer). For example, antenna panel 1 and antenna panel 2 send one or more layers to the corresponding transceiver point 1 and transceiver point 2 based on TPMI1 and TPMI2 respectively.

Figure 2b is a schematic diagram of MP-MTRP transmission under M-DCI (Multi-DCI, multiple downlink control information) scheduling according to an exemplary embodiment. PUSCH transmission can also be based on different PDCCHs, that is, M-DCI scheduling. Multiple PANEL/TRP transmission. Here, multi-antenna panel and multi-transceiver point transmission based on M-DCI scheduling can be based on the transmission of different PUSCHs indicated by different PDCCHs. For example, antenna panel 1 and antenna panel 2 transmit PUSCH1 and PUSCH2 to the corresponding transceiver point 1 and transceiver point 2 based on PDCCH1 and PDCCH2 respectively.

In an actual deployment, the link between transmission points may be a relatively ideal backhaul link that supports high throughput and very low backhaul latency, or it may use xDSL (x Digital Subscriber Line, x Digital Subscriber Line Non-ideal backhaul links such as line), microwave and relay, based on M-DCI NC-JT (non-coherent joint transmission, non-coherent joint transmission). The transmission scheme was originally introduced mainly for non-ideal backhaul situations, but this scheme can also be used for ideal backhaul situations.

In beam management, CSI (Channel State Information) reporting can be used to configure measurement and reporting for beam management, informing the network of the beam information currently suitable for transmission. When the report parameter (reportQuantity) in the report setting (report setting) is configured as "CRI/RSRP" or "SSBRI/RSRP" or "CRI/SINR" or "SSBRI/SINR", it means beam reporting in beam management. At this time The associated resource setting contains multiple CSI-RS (Channel State Information-Reference Signal, Channel State Information Reference Signal) resources or multiple SSB (Synchronization Signal Block, synchronization signal block). The UE checks all resources according to Measurement of RSRP (Reference Signal Receiving Power, reference signal receiving power) and/or SINR (Signal to Interference plus Noise Ratio, signal to interference plus noise ratio) to determine the optimal CRI (CSI-RS Resource Indicator, CSI reference signal Resource indicator) or SSBRI (SSB Resource Index, synchronization signal resource block index).

In order to support the transmission scheduling of downlink reception and uplink transmission of the base station, the receiving beam and transmitting beam of the terminal are not directly indicated in the beam management. The transmitting beam and receiving beam of the terminal are indirectly indicated by the downlink transmitting beam (i.e., reference signal index) of the base station. . The terminal can determine the corresponding downlink receiving beam through the downlink transmitting beam. If an uplink beam exists, the uplink transmitting beam can be determined through the beam consistency (Beam Correspondence) principle.

According to the uplink and downlink reciprocity of the wireless channel corresponding to the antenna, the directions of the uplink transmit beam and downlink receive beam of a wireless communication link are generally the same, and the directions of the receive beam and transmit beam of a device are consistent. This characteristic is called is the beam consistency. Therefore, the terminal measures and reports the downlink transmit beam, which is equivalent to indirectly reporting the terminal's downlink receive beam and/or the terminal's uplink transmit beam.

Beam reporting can be divided into two configurations, one is beam reporting based on beam grouping, and the other is beam reporting not based on beam grouping.

For beam reporting based on beam grouping, the terminal only needs to report the downlink transmission beam. At one reporting moment, the UE can be configured to report N different gNB transmission beams at the same time, and the UE can receive the N different transmission beams at the same time. The network configuration N=2.

Beam reporting that is not based on beam grouping: At one reporting moment, the UE can be configured to report up to N different eNB transmission beams, and N=1, 2, 3, 4. The RSRP of these N beams is relative to the largest RSRP. Values are reported in differential form.

In order to support uplink panel selection and support the enhanced beam reporting scheme, the terminal is notified of the function selected for the uplink transmission panel by updating the UL (Uplink) transmission configuration indication state (TCI state). When the base station receives the CRI/SSBRI+L1-RSRP/L1-SINR corresponding to a certain terminal capability value set index (UE capability value set ID) reported by the terminal, the base station updates the UL TCI with the CSI-RS or SSB recommended by the terminal. Quasi-colocated type D source reference signal (QCL TypeD source RS) in state. The terminal receives the notification from the base station and follows the instructions of the base station to send the target PUSCH or PUCCH (Physical Uplink Control Channel) using the same panel as the receiving QCL Type D source RS.

Among them, the terminal capability value set (UE capability value set) reported by the terminal can include the maximum number of SRS (Sounding Reference Signal, detection reference signal) ports supported by each antenna panel, each CRI/SSBRI and L1- in the beam report RSRP/L1-SINR corresponds to a terminal capability value set index (UE capability value set ID).

In uplink MIMO enhancement, consider implementing simultaneous uplink transmission for multiple TRPs through multiple panel terminals to further improve the uplink system transmission throughput and transmission reliability.

Under the unified TCI framework (unified TCI framework), during the beam reporting process, the corresponding terminal capability value set index (UE capability value set ID) is reported while reporting the beam information CRI/SSBRI and L1-RSRP/L1-SINR. Use It supports reporting the TCI state value (TCI state) to notify the terminal of the function set corresponding to the panel selected for uplink transmission. However, the current panel selection and beam reporting are only applicable when the antenna panels correspond to different UE capability value set indexes. Therefore, when the beams corresponding to the reported UE capability value set indexes are the same, it is impossible to distinguish whether they correspond to the same antenna panel or different ones. The antenna panel cannot distinguish whether the reported beams correspond to different panels, so the base station cannot know whether the reported beams are suitable for supporting the scheduled uplink simultaneous transmission scheme.

In order to support uplink STxMP, the terminal needs to determine two uplink beams from different antenna panels suitable for uplink simultaneous transmission. The beam reporting scheme in the related art cannot support it. In view of this, embodiments of the present disclosure provide a beam reporting method. This method is enhanced based on beam reporting configuration of beam grouping.

Figure 3 is a schematic flowchart of a beam reporting method according to an exemplary embodiment. The beam reporting method is performed by the terminal in the wireless communication system shown in Figure 1. As shown in Figure 3, the beam reporting method may include:

S101: Report beam grouping information to the network device; wherein the beam grouping information indicates beam grouping; the beam grouping information is used to indicate whether the beam pairs in each beam grouping support simultaneous uplink transmission through different antenna panels.

The terminal provided in the embodiment of the present disclosure may be various types of terminals, such as mobile phones, tablet computers, wearable devices, vehicle-mounted terminals and/or Internet of Things terminals, etc.

In the embodiment of the present disclosure, different antenna panels of the terminal have the ability to support simultaneous uplink transmission.

In some examples, the terminal has multiple different antenna panels, and different beams correspond to different antenna panels, where the different beams may have different beam directions.

Different antenna panels of the terminal may be used to receive or transmit beams in different beam directions. For example, different antenna panels of the terminal can receive downlink beams in different beam directions at the same time, and different antenna panels of the terminal can also transmit uplink beams in different beam directions at the same time.

In some examples, different beams correspond to the same antenna panel or different antenna panels of the terminal.

In this embodiment, the terminal can perform CSI measurements for beam management on multiple downlink transmission beams of the network device, obtain corresponding measurement results, and determine the downlink transmission beams that need to be reported simultaneously based on the measurement results. Among them, the measurement results of each beam reported meet the preset conditions.

In some examples, the terminal reports the beam grouping information corresponding to the beam for each of the multiple beams reported simultaneously, where the beam grouping information corresponding to one beam is used to indicate the beam of the downlink receiving beam corresponding to the beam. Group. The downlink receiving beam corresponding to a beam is: the downlink beam used by the terminal to receive the beam.

The preset conditions include: the beam measurement result is greater than a preset threshold. The beam measurements may include beam signal strength values (RSRP) and/or beam signal quality values (eg, SINR).

In this embodiment, at one reporting moment, the UE may be configured to report up to 2N downlink transmit beams at the same time.

The downlink transmit beam is a downlink transmit beam used by network equipment (such as gNB) for beam management measurement configuration, that is, it corresponds to different reference signals, such as CSI-RS or SSB.

In some examples, while reporting beam information corresponding to different beams and beam measurement results to the network device, the terminal reports the beam grouping information corresponding to different beams. Wherein, the beam information includes: reference signal. The beam measurements may include reference signal strength values (RSRP) and/or reference signal quality values (eg, SINR).

In some examples, the 2N may be the maximum number of reporting beams configured or pre-configured by the network or agreed upon by the protocol. For example, the 2N may be 2, 4, 6, etc.

In some examples, the reported beams are at least one of:

Used for simultaneous downlink reception of the terminal and the corresponding uplink beam for uplink transmission of the terminal;

It is used for simultaneous downlink reception of the terminal and does not have a corresponding uplink beam for the uplink transmission of the terminal.

Wherein, the beam used for downlink transmission of the terminal may be used as a receiving beam for downlink transmission to perform the downlink transmission. The beam used for uplink transmission of the terminal may be used as a sending beam for uplink transmission to perform the uplink transmission.

The beam used for downlink transmission of the terminal may include: a beam used only for downlink transmission of the terminal.

The transmit beam used for the terminal's uplink transmission is called the uplink transmit beam (UL Tx beam), and the receive beam used for the terminal's downlink transmission is called the downlink receive beam (DL Rx beam).

When the reference signal used for beam management is configured with corresponding TCI status information, the terminal can know which transmit beam the network device uses to send the reference signal, and can then determine which downlink receive beam to use to receive the signal based on the beam pairing relationship determined by beam measurement.

The terminal can determine the downlink receiving beam corresponding to the reported beam through the beam pairing relationship determined by beam measurement, and if there is a corresponding uplink beam, can determine the uplink transmitting beam corresponding to the downlink receiving beam through beam consistency.

When the downlink receive beam corresponding to the reported beam has beam consistency with an uplink transmit beam, the reported beam has a corresponding relationship with the uplink transmit beam, that is, through the reported beam, the terminal can determine the corresponding uplink transmit beam.

If the beam corresponding to the beam reported by the terminal is only used for the downlink transmission of the terminal, the beam reported by the terminal does not have a corresponding uplink transmission beam used for the uplink transmission of the terminal.

In some examples, the uplink transmission may be signaling transmission, data transmission, or mixed signaling and data transmission.

In some examples, different antenna panels of the terminal support simultaneous downlink transmission of different beams, and when different beams support uplink transmission of the terminal, different antenna panels support simultaneous uplink transmission of different beams. .

In this embodiment, at most 2N downlink transmission beams form at most N beam pairs, wherein the uplink beams corresponding to two beams in each beam pair can be used for uplink simultaneous transmission.

If two beams in a beam pair correspond to uplink transmission beams, and the uplink transmission beams corresponding to the two beams in the beam pair are transmitted by different antenna panels of the terminal, then the two beams in the beam pair The uplink transmission beam corresponding to the beam can be used for uplink simultaneous transmission of the terminal.

In some examples, the number of reported beams is an even number less than or equal to 2N. For example, 2N is 4, and the number of reported beams may be 2 or 4.

For example, it is assumed that the number of measured and reported beams that the terminal can receive simultaneously is four, and the order of the four beams is: beam #1, beam #4, beam #5, and beam #7. Beam #1 and beam #5 are received by the antenna panel #1 of the terminal, and beam #4 and beam #7 are received by the antenna panel #2 of the terminal.

Beam #1 and beam #4 can be used for simultaneous downlink transmission of the terminal. If the uplink beam corresponding to beam #1 and the uplink beam corresponding to beam #4 are both used for the uplink transmission of the terminal, then beam #1 and beam #4 The beam pairs corresponding to 4 can be used for uplink simultaneous transmission of the terminal.

Beam #5 and beam #7 can be used for simultaneous downlink transmission of the terminal. If the uplink beam corresponding to beam #5 and the uplink beam corresponding to beam #7 can both be used for the uplink transmission of the terminal, then beam #5 and The beam pair corresponding to beam #7 can be used for uplink simultaneous transmission of the terminal.

Beam #1 and beam #4 can be used for simultaneous downlink transmission of the terminal. If the uplink beam corresponding to beam #1 and/or the uplink beam corresponding to beam #4 cannot be used for the uplink transmission of the terminal, then beam #1 The beam pair corresponding to beam #4 cannot be used for uplink simultaneous transmission of the terminal.

Beam #5 and beam #7 can be used for simultaneous downlink transmission of the terminal. If the uplink beam corresponding to beam #5 and/or the uplink beam corresponding to beam #7 cannot be used for the uplink transmission of the terminal, then beam #5 The beam pair corresponding to beam #7 cannot be used for uplink simultaneous transmission of the terminal.

In this embodiment, the terminal supports beam reporting based on beam grouping. When "group Based Beam Reporting" in the CSI reporting configuration is set to "Enabled", the terminal can measure from multiple downlink transmit beams. One or more beam pairs that can be received simultaneously are used as reported beams, and beam grouping information is reported separately for each beam in the one or more reported beam pairs.

The beam grouping information is used to indicate whether the beam pairs in each beam group support simultaneous uplink transmission through different antenna panels of the terminal.

In some examples, the beam grouping of the terminal is formed based on a specified grouping manner. The specified grouping method may be determined based on at least one of network configuration, predefinition, and terminal reporting.

When reporting beams, the terminal will report the beam grouping information related to each downlink transmission beam received at the same time to the network device, and each beam grouping information is used to indicate the beam grouping.

After receiving the beam grouping information reported by the terminal, the network device determines the beam grouping indicated by each beam grouping information, and then determines, based on each determined beam grouping, whether the beam pairs corresponding to different beams in the beam grouping support passing through all the beam groups. Simultaneous uplink transmission of different antenna panels of the terminal.

The beam reporting method provided by the embodiment of the present disclosure reports beam grouping information to the network device through the terminal; wherein the beam grouping information indicates the beam grouping; the beam grouping information is used to indicate whether the beam pairs in each beam grouping support different channels. Simultaneous uplink transmission of antenna panels enables the network equipment to determine whether the reported beam pair supports simultaneous uplink transmission through different antenna panels of the terminal based on the beam grouping information corresponding to different beams in the beam pair reported by the terminal, so it can be achieved It is used to support transmission scheduling for simultaneous transmission of multiple uplink panels, further improving the uplink system transmission throughput and transmission reliability.

In one embodiment, the grouping method adopted for the beam grouping is determined based on at least one of network configuration, pre-definition, and terminal reporting.

In the embodiment of the present disclosure, the terminal can implement beam grouping by determining the grouping mode of the terminal's beam grouping through at least one of network device configuration or predefinition or terminal reporting.

In one embodiment, the grouping method adopted for the beam grouping may be a grouping method determined according to the network configuration.

In one embodiment, the method may further include:

Receive beam grouping configuration information sent by the network device, where the beam grouping configuration information is used by the terminal to determine the grouping mode used by the beam grouping.

In this embodiment, the network device can send beam grouping configuration information, so that the terminal can determine the grouping mode used for the beam grouping according to the beam grouping configuration information, so as to use the grouping mode to perform beam grouping.

In one embodiment, the method may further include:

Report beam grouping capability information of the terminal to the network device, where the beam grouping capability information is at least used to indicate: a beam grouping mode supported by the terminal.

Beam grouping can be grouped based on the terminal's downlink receiving beam. Under certain conditions, it can also be grouped based on the terminal's uplink transmitting beam.

The beam grouping capability information may be used to indicate that the terminal supports the grouping method based on the antenna panel, and/or the terminal supports the grouping method based on the downlink receiving beam.

For example, if the terminal supports a grouping method based on downlink reception beams, the network device may send beam grouping configuration information to the terminal. For example, the beam grouping configuration information may instruct the terminal to select a grouping mode based on downlink reception beams as the grouping mode of the beam grouping.

In one embodiment, the grouping mode adopted for the beam grouping may be a predefined grouping mode.

The protocol may stipulate the grouping mode used by the terminal for beam grouping, or the network device and the terminal may negotiate and stipulate the grouping mode used by the terminal for beam grouping.

In one embodiment, the grouping method adopted for the beam grouping may be a grouping method determined according to the terminal report.

In some examples, the terminal only supports the grouping method based on the antenna panel, or only supports the grouping method based on the downlink receiving beam. Before reporting the beam, the terminal may report to the network device the method used by the terminal. Grouping method. In this way, when the terminal needs to report beams later, it can group the beams in a grouping manner reported to the network device in advance.

For example, when the terminal only supports the grouping method based on downlink reception beams, the terminal may report the grouping method based on downlink reception beams adopted by the terminal to the network device.

In other examples, when the terminal supports multiple grouping methods, the terminal can select one of the grouping methods for beam grouping. For example, when the terminal selects a grouping method based on downlink reception beams, the terminal The terminal may report to the network device the grouping method adopted by the terminal based on the downlink receiving beam. In this way, when the terminal needs to report beams later, it can group the beams in a grouping manner reported to the network device in advance.

In some examples, when the terminal supports multiple different grouping methods, the terminal can combine the actual application scenarios and compare the grouping method used this time with the grouping method used this time when reporting beams. The beam grouping information obtained by the grouping method is reported to the network device.

The terminal can report the specifically supported receiving beams or the beam grouping methods of the antenna panel, or both, while reporting the terminal capabilities.

The terminal may also add indication information to specifically indicate the receiving beam or the beam grouping method of the antenna panel corresponding to this CSI measurement report while reporting CSI.

In one embodiment, the beam grouping adopts a grouping method based on an antenna panel; different beam groups correspond to different antenna panels of the terminal.

In some examples, a terminal may form different beam groupings for different antenna panels. One antenna panel corresponds to one beam grouping.

In other examples, the terminal may select an antenna sub-array from at least part of the plurality of antenna panels, and form different beam groups for the different selected antenna sub-arrays. An antenna subarray on an antenna panel corresponds to a beam grouping.

In some examples, an antenna panel includes one or more antennas; the antennas of the terminal constitute an antenna array; and the antenna sub-array includes part of the antennas of the antenna array.

In other examples, an antenna panel includes one or more antenna ports; the antenna ports of the terminal constitute an antenna array; and the antenna sub-array includes part of the antenna ports of the antenna array.

In some examples, the beam grouping may be a beam grouping index value.

For example, if the terminal has antenna panel #1 and antenna panel #2, antenna panel #1 can correspond to beam grouping #1, and antenna panel #2 can correspond to beam grouping #2. Among them, the beam group index value of beam group #1 can be beam group #1, and the beam group index value of beam group #2 can be beam group #2.

If the reported beam #1 is received by the downlink receiving beam corresponding to antenna panel #1, the beam group index value reported by the terminal for beam #1 is beam group #1.

If the reported beam #2 is received by the downlink receiving beam corresponding to the antenna panel #2, the beam group index value reported by the terminal for beam #2 is beam group #2.

In the embodiment of the present disclosure, the terminal can perform beam grouping through antenna panel-based grouping, which can reduce the implementation complexity of beam grouping.

In one embodiment, uplink transmitting beams corresponding to different beams indicated in the same beam grouping cannot be used for uplink simultaneous transmission of the terminal, and uplink transmitting beams corresponding to different beams indicated in different beam groups can be used. Simultaneous uplink transmission on the terminal.

One said beam grouping may indicate one beam or a plurality of different beams.

Based on the grouping mode of the antenna panel, when the same beam grouping indicates multiple different beams, the uplink transmission beams corresponding to the multiple different beams cannot be used for uplink simultaneous transmission of the terminal. Different beam groups indicate that uplink transmission beams corresponding to multiple different beams can be used for uplink simultaneous transmission of the terminal. Different uplink transmission beams that can be used for uplink simultaneous transmission of the terminal correspond to different antenna panels of the terminal.

If the beam grouping information corresponding to different beams indicates that the beam groups corresponding to different beams are the same beam group, it can be determined that the terminal cannot support uplink simultaneous transmission of different beams.

If the beam grouping information corresponding to different beams indicates that the beam groups corresponding to different beams are different beam groups, it can be determined that the terminal can support uplink simultaneous transmission of different beams.

For example, the terminal adopts a grouping method based on antenna panels. Antenna panel #1 corresponds to beam group #1, antenna panel #2 corresponds to beam group #2, and the beam group index value of beam group #1 is beam group #1. The beam group index value of #2 is beam group#2.

If the terminal reports beam group #1 and beam group #2 for beam #1 and beam #2 respectively, the network device can determine the beam group index value after receiving beam group #1 and beam group #2. Beam group #1 indicated by beam group #1 and beam group #2 indicated by beam group #2 are different beam groups. Different downlink receiving beams corresponding to different beam groups divided based on the grouping method of the antenna panel can be used for the above For the terminal's simultaneous downlink transmission, the network device can determine through the beam grouping information that the beam pair corresponding to beam #1 and beam #2 can also be used for the terminal's simultaneous uplink transmission.

If the terminal reports beam grouping information for beam #1 and beam #2, both beam grouping information is beam group#1. After receiving beam group#1, the network device can determine the beam grouping information reported for beam #1 and the beam grouping information reported for beam #2. The beam grouping information indicates the same beam grouping. Since the uplink transmitting beams corresponding to different beams indicated by the same beam grouping divided based on the grouping method of the antenna panel cannot be used for the uplink simultaneous transmission of the terminal, the network device can use the beam grouping information to It is further determined that the beam pair corresponding to beam #1 and beam #2 cannot be used for uplink simultaneous transmission of the terminal.

In one embodiment, the beam grouping adopts a grouping method based on downlink receiving beams; different beams in the same beam group correspond to different antenna panels of the terminal.

Specifically, the beam grouping adopts a grouping method based on downlink reception beams, and different downlink reception beams in the beam group correspond to different antenna panels of the terminal.

For example, if the terminal has antenna panel #1 and antenna panel #2, antenna panel #1 corresponds to downlink receive beam #1 and downlink receive beam #3, and antenna panel #2 corresponds to downlink receive beam #2 and downlink receive beam #2. Receive beam #4.

For example, the terminal can perform beam grouping on the four measured beams that can be received simultaneously, in which downlink receiving beam #1 and downlink receiving beam #2 are divided into beam group #1, and downlink receiving beam #3 and downlink receiving beam #4 are divided into Beam Grouping #2. The beam group index value of beam group #1 can be recorded as beam group #1, and the beam group index value of beam group #2 can be recorded as beam group #2.

If the reported beam #1 is received by the downlink receiving beam #1, the beam group index value reported by the terminal for beam #1 is beam group #1.

If the reported beam #2 is received by the downlink receiving beam #2, the beam group index value reported by the terminal for beam #2 is beam group #1.

If the reported beam #3 is received by the downlink receiving beam #3, the beam group index value reported by the terminal for beam #3 is beam group #2.

If the reported beam #4 is received by the downlink receiving beam #4, the beam group index value reported by the terminal for beam #4 is beam group #2.

For another example, downlink reception beam #1 and downlink reception beam #4 may be divided into beam group #1. Downlink reception beam #2 and downlink reception beam #3 are divided into beam group #2.

In this embodiment of the present disclosure, the terminal may perform beam grouping based on downlink reception beam grouping, which can reduce the implementation complexity of beam grouping.

In one embodiment, the uplink transmit beam and the downlink receive beam of the terminal have beam consistency; the uplink transmit beams corresponding to different beams in the same beam group can be used for the terminal's uplink simultaneous transmission, and are different The uplink transmission beams corresponding to different beams in the beam group cannot be used for uplink simultaneous transmission of the terminal.

Beam grouping adopts a grouping method based on downlink receiving beams, and the same beam grouping can indicate multiple different beams.

The uplink transmitting beam and the downlink receiving beam of the terminal have beam consistency, and the uplink transmitting beam of the terminal is the downlink receiving beam of the terminal.

Uplink transmission beams corresponding to multiple different beams in the same beam group can be used for uplink simultaneous transmission of the terminal. Uplink transmission beams corresponding to multiple different beams in different beam groups cannot be used for uplink simultaneous transmission of the terminal.

Therefore, the terminal uses a grouping method based on downlink receiving beams to perform beam grouping. When reporting beams, by reporting beam grouping information, the network device can determine whether the terminal supports different beams based on the beam grouping information corresponding to each beam. Simultaneous uplink transmission.

Based on the grouping method of downlink receiving beams, if the beam grouping information corresponding to different beams indicates that the beam groups corresponding to different beams are the same beam grouping, it can be determined that the terminal can support uplink simultaneous transmission of different beams.

If the beam grouping information corresponding to different beams indicates that the beam groups corresponding to different beams are different beam groups, it can be determined that the terminal cannot support uplink simultaneous transmission of different beams.

For example, based on the grouping method of downlink reception beams, beam group #1 includes beam #1 and beam #2. Beam group #2 includes beam #3 and beam #4. The beam group index value of beam group #1 is beam group #1, and the beam group index value of beam group #2 is beam group #2.

For beam #1 and beam #3, the beam group index values reported by the terminal are beam group #1 and beam group #2 respectively. After the network device receives beam group #1 and beam group #2, due to the beam group index value beam group Beam group #1 indicated by #1 and beam group #2 indicated by beam group #2 are different beam groups, and the uplink transmit beams corresponding to the different beams indicated by the different beam groups divided based on the grouping method of the downlink receive beam cannot be used. For the simultaneous uplink transmission of the terminal, the network device may determine that the beam pair corresponding to beam #1 and beam #3 cannot be used for the simultaneous uplink transmission of the terminal.

For beam #1 and beam #2, the beam group index values reported by the terminal are both beam group #1. After the network device receives beam group #1, due to the beam group index value for beam #1 and the beam group of beam #2 The index value indicates the same beam group, and since different downlink receive beams corresponding to the same beam group divided based on the grouping mode of the downlink receive beam can be used for downlink simultaneous transmission of the terminal, the network device can determine beam #1 and beam The beam pair corresponding to #2 can be used for uplink simultaneous transmission of the terminal.

It is worth noting that the terminal has beam consistency. When the terminal does not have an antenna panel that only supports downlink transmission, that is, all beams of the terminal can support downlink transmission and can support uplink transmission. In this case In this case, the grouping method based on the downlink receiving beam is equivalent to the grouping method based on the uplink transmitting beam.

In the grouping method based on downlink receive beams, one beam group may contain different beams on multiple antenna panels. When the terminal has many physical antenna panels, compared to the grouping method based on antenna panels, the indication overhead of beam grouping information can be reduced. At the same time, Better not to expose the specific implementation of the terminal.

In one embodiment, the beam grouping information is a beam group index value of the beam grouping.

Specifically, the beam group index value is used to indicate the beam grouping. For example, the beam group index value is a beam group number, etc.

In one embodiment, the beam group index value is used to schedule the transmission type supported by the beam corresponding to the beam group index value.

In one embodiment, the transmission type includes at least one of the following:

Supports downlink transmission and uplink simultaneous transmission;

Supports downlink transmission and uplink non-simultaneous transmission;

Only downstream transmission is supported.

The beam that supports downlink transmission and supports simultaneous uplink transmission can be used as a downlink receiving beam of the terminal for downlink transmission, or can be used as an uplink transmitting beam of the terminal for uplink transmission.

All reported beams need to report the beam group index value obtained according to the corresponding beam grouping method. However, for the antenna panel of the terminal that only supports downlink transmission or the beam that only supports downlink transmission, the beam group index value corresponding to the beam is set is the default.

For the antenna panel of the terminal that only supports downlink transmission or the beam that only supports downlink transmission, the beam group index value corresponding to the reported beam is set to default, that is, the reported beam can only be used for downlink simultaneous transmission and When there is no corresponding uplink transmission beam, the beam grouping index value corresponding to the beam is not reported.

Here are some examples:

Assume that the grouping method based on downlink receiving beams is adopted. Beam group #1 includes beam #1 and beam #2, beam group #2 includes beam #3 and beam #4, and beam group #3 includes beam #5 and beam #. 6. The beam group index value of beam group #1 is beam group #1, the beam group index value of beam group #2 is beam group #2, and the beam group index value of beam group #3 is beam group #3. Among them, beam #1 and beam #2 support downlink transmission and uplink simultaneous transmission, beam #3 and beam #4 support downlink transmission and uplink simultaneous transmission, and beam #5 and beam #6 only support downlink transmission.

The beam group index values reported by the terminal for beam #1 and beam #2 are both beam group #1. Based on beam group #1, the network device can determine that the transmission type supported by beam #1 and beam #2 is to support downlink transmission and support uplink transmission.

The beam group index values reported by the terminal for beam #3 and beam #4 are both beam group #2. Based on beam group #2, the network device can determine that the transmission type supported by beam #3 and beam #4 is to support downlink transmission and support uplink transmitted simultaneously.

The beam group index values reported by the terminal for beam #5 and beam #6 are both beam group #3. Based on beam group #3, the network device can determine that the transmission type of beam #5 and beam #6 only supports downlink transmission.

In the above example, when the beam corresponds to an antenna panel that only supports downlink transmission, the corresponding beam group index value is reported by default. It means that this beam pair can only support downlink transmission, and the beam grouping index value corresponding to the beam is not reported.

In one embodiment, for the antenna panel of the terminal that only supports downlink transmission or the beam that only supports downlink transmission, the beam group index value corresponding to the beam is set to default, indicating that the beam corresponding to the beam is not reported. Beam grouping index value.

In some examples, when the beam grouping index value is set to the default value, the beam grouping index value is set to the default value. For example, the default value is "0", and the value of the beam grouping index value that is not set as the default can be set to start from "1".

For the antenna panel of the terminal that only supports downlink transmission or the beam that only supports downlink transmission, the beam group index value corresponding to the reported beam is set to default, that is, the reported beam can only be used for downlink simultaneous transmission and When there is no corresponding uplink transmission beam, the beam grouping index value corresponding to the beam is not reported. In this way, the load overhead during beam reporting can be effectively reduced and resource utilization improved.

In one embodiment, the beam grouping information is used to determine different uplink transmission beams of the terminal based on supporting uplink simultaneous multi-panel transmission (STxMP).

In this embodiment, by determining the different uplink transmission beams of the terminal based on uplink STxMP support, transmission scheduling for supporting uplink multi-panel simultaneous transmission can be implemented, further improving the uplink system transmission throughput and transmission reliability.

In one embodiment, as shown in Figure 4, reporting beam grouping information to the network device may include:

S201: Report a channel state information report based on beam grouping to the network device, where the channel state information report contains beam grouping information, and the channel state information report contains or does not contain a terminal capability value set index.

Does the channel state of beam grouping mean that one group corresponds to one channel state or does each beam correspond to one channel state?

The terminal capability value set index can be used to notify the terminal to select a panel for uplink transmission by updating the TCI status value.

For example, the terminal may report a channel state information report based on beam grouping to the network device in a preset reporting manner. Wherein, the preset reporting method is used to instruct the terminal to report a periodic behavior of the channel state information report.

The reporting method of the channel state information report may be the network device configuration or pre-configuration or protocol agreement.

In this embodiment, the terminal supports CSI measurement reporting configured to be based on beam grouping. The terminal can measure the reported beams, determine the beam grouping corresponding to the reported beam, and group the beams corresponding to each beam reported simultaneously. The information is included in the CSI report, and the CSI report is reported to the network device.

Here, CSI measurement reporting based on beam grouping is a CSI measurement reporting method configured by the network. It is used to measure the beam pair that is most suitable for supporting simultaneous downlink reception by the terminal and report it to the network. One CSI measurement report is configured with 2N beams, and one CSI reporting opportunity also includes the reporting of these 2N beams.

In the beam reporting of related technologies, for each beam reported, the beam information CRI/SSBRI of the beam and the measurement results L1-RSRP/L1-SINR and a corresponding terminal capability value index (UE capability value set ID) will be reported. In the embodiment of the present disclosure, for each reported beam, the beam information CRI/SSBRI of the beam and the measurement result L1-RSRP/L1-SINR and a corresponding terminal capability value index are reported, and the beam corresponding to the beam is also reported. The group index value, that is, the reported content of a beam is {CRI/SSBRI+L1-RSRP/L1-SINR, UE capability value set ID, beam group ID}, in which the UE capability value set ID can be optionally reported.

Since the beam grouping information can be reflected in the reported content of each beam in the reported beam pair, it can indicate the two beams that the terminal receives simultaneously in downlink.

By combining the beam grouping method used by the terminal and the beam grouping index values corresponding to different beams in the beam pair reported by the terminal, the network device obtains the corresponding information of the uplink transmission beam of the corresponding terminal, and can determine the reported beam pair. The transmission types supported by different beams, for example, support simultaneous uplink transmission, or uplink transmission that does not support simultaneous transmission, or only support simultaneous downlink reception.

In one embodiment, the method may further include:

When the reporting mode of the channel state information report is configuration or preconfiguration of the network side device, configuration information of the network device is received, wherein the configuration information includes a reporting mode of the channel state information report.

For example, the reporting method can be configured through the reporting configuration type (ReportConfigureType) in the reporting configuration (report setting). The reporting method is aperiodic CSI (AP-CSI) reporting, periodic CSI (P-CSI) reporting or semi-persistent CSI (SP-CSI) reporting.

In one embodiment, the reporting method of the channel state information report is periodic reporting, aperiodic reporting or semi-persistent reporting.

Among them, the channel status information report reporting method defaults to periodic reporting.

In this embodiment, the reporting method of the channel state information report may be configured by the network device through high-level signaling, for example, RRC (Radio Resource Control, Radio Resource Control) signaling, which is not limited in this embodiment. .

In one embodiment, the beam grouping information is used to schedule uplink transmission based on S-DCI; or the beam grouping information is used to schedule uplink transmission based on M-DCI.

Exemplarily, the network device determines beam pairs corresponding to at most 2N beams for uplink simultaneous transmission according to the beam grouping information, and based on the determined beam pairs corresponding to at most 2N beams for uplink simultaneous transmission, the scheduling is based on Uplink transmission of S-DCI, or scheduling uplink transmission based on S-DCI.

In some examples, the uplink transmission may be signaling, data, or signaling/data mixed transmission.

In some examples, the uplink transmission is PUSCH transmission.

In one embodiment, the number of beam pairs is at most N; at most N beam pairs are composed of at most 2N beams according to default rules; where 2N is the maximum number of reported beams, and N is greater than or equal to A positive integer of 1.

Wherein, when N is equal to 1, at most 2N beams are divided into one beam pair.

When N is greater than 1, default rules may be used to divide up to 2N beams into N beam pairs.

Specifically, the default rule may be: according to the reporting order of the reporting content corresponding to the at most 2N beams, at most 2N beams are sequentially combined into N beam pairs.

For example, the terminal measures that the beams that can be received simultaneously are: beam #1, beam #5, beam #2 and beam #3. Assume that beam #1 and beam #5 are a beam pair, and beam #2 and beam #3 is a beam pair, then the order of the reported beam information corresponding to each beam can be CRI#1, CRI#5, CRI#2, and CRI#3. Among them, CRI#1 is the beam information corresponding to beam #1, CRI#5 is the beam information corresponding to beam #5, CRI#2 is the beam information corresponding to beam #2, and CRI#3 is the beam information corresponding to beam #3.

Terminals in the related art only support reporting one beam pair. The disclosed embodiment can be extended to N beam pairs, and the default rules are used to pair the reported 2N beams in pairs. For example, if a maximum of 4 beams are configured to be reported, the reported content of each reported beam will be sorted accordingly in the CSI Reporting.

For example, when beam #1 and beam #2, beam #3 and beam #4 are reported by the terminal, beam #1 and beam #2 form a beam pair, and beam #3 and beam #4 form a beam pair, then these four The reported contents of the beams are ordered as follows: the reported contents of beam #1, the reported contents of beam #2, the reported contents of beam #3 and the reported contents of beam #4.

It can be understood that when N is greater than 1, other methods may be used to divide up to 2N beams into at most N beam pairs. This embodiment does not limit the specific implementation method.

Figure 5 is a schematic flowchart of a beam reporting method according to an exemplary embodiment. The beam reporting method is executed by the network device in the wireless communication system shown in Figure 1. As shown in Figure 5, the beam reporting method may include:

S301: Receive beam grouping information reported by the terminal; wherein the beam grouping information indicates beam grouping; the beam grouping information is used to indicate whether the beam pairs in each beam grouping support simultaneous uplink transmission through different antenna panels.

The network equipment in the embodiments of the present disclosure may be various types of base stations, such as base stations of the 5G system or other evolved base stations.

In some examples, the terminal has multiple different antenna panels, and different beams correspond to different antenna panels, wherein different beams may have different beam directions.

In this embodiment, at one reporting moment, the UE may be configured to report at least 2N downlink transmit beams simultaneously.

In some examples, while receiving the beam information corresponding to different beams and beam measurement results reported by the terminal, the network device receives the beam grouping information corresponding to different beams reported by the terminal. Wherein, the beam information includes: reference signal. The beam measurements may include reference signal strength values (RSRP) and/or reference signal quality values (eg, SINR).

In some examples, the reported beams are at least one of:

In this embodiment, the transmit beam used by the terminal for uplink transmission is called an uplink transmit beam (UL Tx beam), and the receive beam used by the terminal for downlink transmission is called a downlink receive beam (DL Rx beam).

If the beam corresponding to the beam reported by the terminal is only used for downlink transmission of the terminal, the beam reported by the terminal does not have a corresponding uplink transmission beam.

In this embodiment, at most 2N downlink transmission beams form at most N beam pairs, wherein the uplink beams corresponding to the two beams in each beam pair can be used for simultaneous uplink and downlink transmission.

For example, it is assumed that the number of measured and reported beams that the terminal can receive simultaneously is four, and the order of the four beams is: beam #1, beam #4, beam #5, and beam #7. Beam #1 and beam #5 are received by the antenna panel #1 of the terminal, and beam #2 and beam #4 are received by the antenna panel #2 of the terminal.

Beam #1 and beam #4 can be used for simultaneous downlink transmission of the terminal. If the uplink beam corresponding to beam #1 and the uplink beam corresponding to beam #4 can both be used for the uplink transmission of the terminal, then beam #1 and The beam pair corresponding to beam #4 can be used for uplink simultaneous transmission of the terminal.

In this embodiment, the terminal supports beam reporting based on beam grouping. When "group Based Beam Reporting" in the CSI reporting configuration is set to "Enabled", the terminal can transmit beams from multiple downlinks received simultaneously. Select the beams that need to be reported, and report beam grouping information for each of the selected multiple beams.

When reporting beams, the terminal will report beam grouping information related to each downlink transmission beam received at the same time to the network device. The beam grouping information related to each beam is used to indicate the beam grouping.

After receiving the beam grouping information reported by the terminal, the network device determines that each beam grouping information indicates a beam grouping, and then determines based on each beam grouping whether the beam pairs corresponding to different beams in the beam grouping can be used for the terminal. of uplink transmission simultaneously.

The beam reporting method provided by the embodiment of the present disclosure receives the beam grouping information reported by the terminal through the network device; wherein the beam grouping information indicates the beam grouping; the beam grouping information is used to indicate whether the beam pair in each beam grouping supports passing Simultaneous uplink transmission of different antenna panels, whereby the network device can determine whether the reported beam pair supports simultaneous uplink transmission through different antenna panels of the terminal based on the beam grouping information corresponding to different beams in the beam pair reported by the terminal, so it can be achieved It is used to support transmission scheduling for simultaneous transmission of multiple uplink panels, further improving the uplink system transmission throughput and transmission reliability.

In the embodiment of the present disclosure, the beam grouping of the terminal can be implemented by determining the grouping method of the terminal's beam grouping by at least one of network device configuration or predefinition or terminal reporting.

In one embodiment, the method may further include:

Beam grouping configuration information sent to the terminal, wherein the beam grouping configuration information is used by the terminal to determine the grouping mode used for the beam grouping.

In one embodiment, the method may further include:

Receive beam grouping capability information of the terminal reported by the terminal, where the beam grouping capability information is at least used to indicate: a beam grouping mode supported by the terminal.

For example, when the terminal only supports the grouping method based on downlink reception beams, the terminal may report to the network device the grouping method based on downlink reception beams adopted by the terminal.

In still other examples, when the terminal supports multiple different grouping methods, the network device receives the grouping method used by the terminal this time and the beam grouping information obtained based on the grouping method used this time.

In some examples, the antennas of one terminal constitute an antenna array; the antenna sub-array includes portions of the antennas of the antenna array.

In the embodiment of the present disclosure, the beam grouping of the terminal is performed through a grouping method based on the antenna panel, which can reduce the implementation complexity of the beam grouping.

In one embodiment, uplink transmitting beams corresponding to different beams indicated in the same beam grouping cannot be used for uplink simultaneous transmission of the terminal, and uplink transmitting beams corresponding to different beams indicated in different beam groups can be used. Simultaneously transmitted in the uplink of the terminal.

One said beam grouping may indicate one beam or a plurality of different beams.

When the same beam group indicates multiple different beams, the uplink transmission beams corresponding to the multiple different beams cannot be used for the uplink simultaneous transmission of the terminal. Different beam groups indicate that uplink transmission beams corresponding to multiple different beams can be used for uplink simultaneous transmission of the terminal, and the different uplink transmission beams that can be used for uplink simultaneous transmission of the terminal correspond to different antennas of the terminal panel.

If the terminal reports beam group #1 and beam group #2 for beam #1 and beam #2 respectively, the network device can determine the beam group information beam after receiving beam group #1 and beam group #2. Beam group #1 indicated by group#1 and beam group #2 indicated by beam group#2 are different beam groups. Different downlink receiving beams corresponding to different beam groups divided based on the grouping method of the antenna panel can be used for the terminal. of simultaneous downlink transmission, then the network device can determine that the beam pair corresponding to beam #1 and beam #2 can also be used for the terminal's simultaneous uplink transmission.

If the terminal reports beam grouping index values for beam #1 and beam #2, both are beam group #1. After receiving beam group #1, the network device can determine the beam grouping information reported for beam #1 and beam #2. The beam grouping information indicates the same beam grouping. Since the uplink transmitting beams corresponding to different beams indicated by the same beam grouping divided based on the grouping method of the antenna panel cannot be used for the uplink simultaneous transmission of the terminal, the network equipment uses the beam grouping information. It may further be determined that the beam pair corresponding to beam #1 and beam #2 cannot be used for uplink simultaneous transmission of the terminal.

For example, the terminal may perform beam grouping on four measured beams that can be received simultaneously, wherein downlink receiving beam #1 and downlink receiving beam #2 are divided into beam grouping #1. Downlink reception beam #3 and downlink reception beam #4 are divided into beam group #2. The beam group index value of beam group #1 can be recorded as beam group #1, and the beam group index value of beam group #2 can be recorded as beam group #2.

In the embodiment of the present disclosure, the beam grouping of the terminal is performed based on the downlink reception beam grouping method, which can reduce the implementation complexity of the beam grouping.

If the beam group information corresponding to different beams indicates that the beam groups corresponding to different beams are the same beam group, it can be determined that the terminal can support uplink simultaneous transmission of different beams.

For example, based on the grouping method of downlink receive beams, beam group #1 includes beam #1 and beam #2, beam group #2 includes beam #3 and beam #4, and the beam group index value of beam group #1 is beam group #1, the beam group index value of beam group #2 is beam group#2.

It is worth noting that the terminal has beam consistency. If the terminal does not have a beam that only supports downlink transmission, that is, all beams of the terminal can support downlink transmission and can support uplink transmission. In this case, The grouping method based on downlink receive beams is equivalent to the grouping method based on uplink transmit beams.

In one embodiment, the beam group index value is used for the network device to schedule the transmission type supported by the beam corresponding to the beam group index value.

Supports downlink transmission and uplink simultaneous transmission;

Supports downlink transmission and uplink non-simultaneous transmission;

Only downstream transmission is supported.

For the antenna panel of the terminal that only supports downlink transmission or the beam that only supports downlink transmission, the beam group index value corresponding to the reported beam is set to default, that is, the reported beam can only be used for downlink simultaneous transmission and There is no corresponding uplink transmit beam.

Here are some examples:

Assume that the beam grouping adopts the grouping method based on the downlink receiving beam. Beam grouping #1 includes beam #1 and beam #2, beam grouping #2 includes beam #3 and beam #4, and beam grouping #3 includes beam #5 and beam #2. Beam #6. The beam group index value of beam group #1 is beam group #1, the beam group index value of beam group #2 is beam group #2, and the beam group index value of beam group #3 is beam group #3. Among them, beam #1 and beam #2 support downlink transmission and uplink simultaneous transmission, beam #3 and beam #4 support downlink transmission and uplink simultaneous transmission, and beam #5 and beam #6 only support downlink transmission.

In the above example, one of the beams corresponds to an antenna panel that only supports downlink transmission, and the corresponding beam group index value is reported by default. It means that this beam pair can only support downlink transmission.

In one embodiment, for the antenna panel of the terminal that only supports downlink transmission or the beam that only supports downlink transmission, the beam grouping index value corresponding to the beam is set to default.

In this embodiment, for the antenna panel of the terminal that only supports downlink transmission or the beam that only supports downlink transmission, the beam group index value corresponding to the beam is set to default, that is, the reported beam can only be used for downlink When transmitting simultaneously and there is no corresponding uplink transmission beam, the beam grouping index value corresponding to the beam is not reported.

In one embodiment, the beam grouping information is used to determine different uplink transmission beams for the terminal to simultaneously transmit STxMP based on multi-panel uplink transmission.

In this embodiment, by determining the terminal's different uplink transmission beams based on supporting uplink multi-panel simultaneous transmission of STxMP, transmission scheduling for supporting uplink multi-panel simultaneous transmission can be implemented, further improving the uplink system transmission throughput and transmission reliability.

In one embodiment, as shown in Figure 6, receiving beam grouping information reported by the terminal may include:

S401: Receive a channel state information report based on beam grouping reported by the terminal, where the channel state information report contains beam grouping information, and the channel state information report contains or does not contain a terminal capability value set index.

For example, the channel state information report may be reported by the terminal according to a preset reporting manner. Wherein, the preset reporting method is used to instruct the terminal to report a periodic behavior of the channel state information report.

By combining the beam grouping method used by the terminal and the beam grouping index values corresponding to different beams in the beam pair reported by the terminal, the network device obtains the corresponding information of the uplink transmission beam of the corresponding terminal, and can determine the different information in the reported beam pair. The transmission type supported by the beam, for example, supports simultaneous uplink transmission, or other uplink transmission that does not support simultaneous transmission, or only supports simultaneous downlink reception.

In one embodiment, the method may further include:

The beam reporting method provided by the embodiments of the present disclosure groups antenna panels or downlink receiving beams, and separately reports the beam grouping ID for each transmit beam pair.

This method can support reporting of UE capability set ID or not reporting of UE capability set ID.

In one embodiment, the reporting is performed based on the grouping method of the UE antenna panel. For example, one panel of the UE is divided into one group.

The uplink sending beams corresponding to different downlink receiving beams indicated by different packets can be sent at the same time, but the uplink sending beams corresponding to different downlink receiving beams indicated by the same grouping cannot be sent at the same time. Therefore, by reporting the ID of each beam corresponding to different UE antenna groups, it is possible to distinguish whether the transmission type supports simultaneous uplink transmission.

In one embodiment, reporting is performed based on the grouping method of downlink receive beams (uplink transmit beams when beam consistency is established).

A receive beam group is formed by selecting a downlink receive beam in each panel of the UE. Different uplink sending beams corresponding to the same group can be sent at the same time, but different uplink sending beams corresponding to different groups cannot be sent at the same time.

In one embodiment, the relevant indication of the beam group ID may be indicated by 1 bit or 2 bits.

For beams supported by both DL and UL, relevant indications of beam group IDs are added.

The beam group ID corresponding to the downlink DL-only beam can be set to default.

In one embodiment, the transmission types supported by the beam include at least one of the following:

Supports downlink transmission and uplink simultaneous transmission;

Supports downlink transmission and uplink non-simultaneous transmission;

Only downstream transmission is supported.

In some examples, the beam group ID corresponding to the downlink DL-only beam may be set to default.

In some examples, enhanced measurement reporting supporting STxMP transmission is used for the beam group ID and is also used for P-CSI/SP-CSI/AP-CSI.

In some examples, enhanced measurement reporting that supports STxMP transmission supports P-CSI by default, where supporting SP-CSI/AP-CSI is an optional capability of the UE.

In some examples, for STxMP transmission, beam measurement reporting can be used to schedule uplink S-DCI-based transmission or M-DCI-based transmission.

In this disclosed embodiment, the existing beam reporting mechanism is enhanced to support the network side to confirm two beams that can be used for simultaneous uplink multi-panel transmission to support transmission scheduling for uplink multi-panel simultaneous transmission.
