The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

The network architecture and the service scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not form a limitation on the technical solution provided in the embodiment of the present application, and as a person of ordinary skill in the art knows that along with the evolution of the network architecture and the appearance of a new service scenario, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

Referring to fig. 1, the technical solution provided in the embodiment of the present application is applied to a communication system, where the system includes a network-side device 11 and a terminal device 10, and in a future 5G system architecture, the network-side device 11 is a device for providing a wireless communication function for the terminal, and includes but is not limited to: a gbb in 5G, a Radio Network Controller (RNC), a Node B (NB), a Base Station Controller (BSC), a Base Transceiver Station (BTS), a home base station (e.g., home evolved node B or home node B, HNB), a BaseBand Unit (BBU), a transmission point (TRP), a Transmission Point (TP), a mobile switching center (msc), and the like. The base station in the present application may also be a device that provides the terminal with a wireless communication function in other communication systems that may appear in the future.

A TRP in embodiments herein may refer to any component (or collection of components) used to provide wireless access to a network, such as a macrocell, femtocell, Wi-Fi Access Point (AP), or other wireless communication enabled device. The network TRP may provide wireless chickens according to one or more wireless communication protocols, such as a 5 th generation new radio (5)^thgeneral radio, 5G _ NR), Long Term Evolution (LTE), LTE-addressed (LTE-A), High Speed Packet Access (HSPA), wi-fi 802.11a/b/G/n/ac, and the like.

Terminal device 10 is a device that can provide voice and/or data connectivity to a user. For example, the terminal device includes a handheld device, an in-vehicle device, and the like having a wireless connection function. Currently, the terminal device may be: a mobile phone (mobile phone), a tablet computer, a notebook computer, a palm top computer, a Mobile Internet Device (MID), a wearable device, a Virtual Reality (VR) device, an Augmented Reality (AR) device, a wireless terminal in industrial control (industrial control), a wireless terminal in self driving (self driving), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), and the like.

It should be noted that the above system architecture is only an example of the system architecture applicable to the embodiment of the present invention, and the system architecture applicable to the embodiment of the present invention may also add other entities or reduce part of the entities compared to the system architecture shown in fig. 1.

Generally, for a terminal in which a plurality of panels are arranged, the orientations of the plurality of panels are greatly different, and thus spatialrelalationinfo, which is a Quasi-Co-Location (QCL) corresponding to uplink PUSCH transmission of the plurality of panels, is different.

When the terminal equipment respectively sends data from different panels, the difference of each sending point in space can cause the difference of large-scale channel parameters of a receiving link at the base station end, and the large-scale parameters of the channel directly influence the adjustment and optimization of filter coefficients during channel estimation.

At present, a downlink URLLC service is scheduled based on a single PDCCH, and transmission of an ideal idle backhaul loop is considered, so in the technical scheme provided in the embodiment of the present application, an uplink transmission condition is also based on scheduling of a single PDCCH, that is, a single DCI, on the premise of idle backhaul. Thus, for one PUSCH channel transmission, the URLLC service is also in progress for multiple panel enhancements for uplink transmission, the principle is basically as shown in fig. 2 below. The UE sends the same or different data in different panels, and the PUSCH transmission is enhanced through one or a combination of time domain/frequency domain/space domain data transmission multiplexing modes so as to improve the reliability of the URLLC service. For example, as the terminal device rotates, the terminal device may adjust the actual beam pointing of the multiple antenna panels at a higher frequency in order to maintain connectivity with the network. Different TRPs can monitor the same set of SRS resources or different sets of SRS resources, and the base station finds different SRS resources (SRI-1 and SRI-2) corresponding to TRP-1 and TRP-2 reception and suitable for transmission, and respectively correspond to different QCL relations, namely spatialRelationInfo-1 and spatialRelationInfo-2.

The following describes a beam management method in the embodiment of the present application by taking the system architecture described in fig. 1 as an example. As shown in fig. 3:

in step S101, the UE reports the capability information to the base station. The capability information may be capability information identifying that the UE supports joint transmission of multiple panels.

In step S102, the base station configures one or more sets of SRS resource sets managed by user beams for the UE.

In step S103, the UE may transmit SRS signals over multiple panels based on the set of SRS resources allocated by the base station.

In step S104, the base station measures the received multiple uplink channel sounding signals to obtain a beam measurement result. Then, in step S105, the base station selects a beam and/or a beam combination for the UE for multiple panel joint uplink transmissions according to the beam measurement result. Thereafter, in step S106, the base station generates configuration information indicating the beam and/or beam combination selected by the base station to the UE.

Up to this point, in step S107, the UE performs operations related to the multi-panel joint uplink transmission according to the configuration information of the base station.

In the embodiment of the application, because the UE can realize the joint uplink transmission by using multiple panels, the utilization rate of the panels can be improved, and the requirement of supporting the reliability enhancement of the URLLC service in the uplink channel direction is met.

Of course, in another embodiment, the base station may also select a beam or a beam combination for the UE according to the known beam information. For example, the base station may select a beam or a combination of beams for a UE that supports beam consistency using beams available for uplink and downlink known transmissions. For example, the uplink beam used by the random access channel may be used for selection as the uplink beam.

In addition, in specific implementation, a beam and/or a beam combination may be selected according to the beam measurement result, and then the beam and/or the beam combination may be selected based on the known beam information, and the beam and/or the beam combination selected by the two methods may be jointly indicated to the UE for the UE to use.

The following description is made in relation to an implementation in which the base station implements and instructs a selected beam or beam combination.

1) Base station selecting beam and/or beam combination

In one embodiment, a base station measures signal quality measurement results of a plurality of uplink channel sounding signals sent by a plurality of panels corresponding to a UE on each TRP of the base station; then, a beam and/or a beam combination meeting the specified conditions that can be jointly received by different TRPs and the channel quality satisfies the conditions for reception is selected according to the signal quality measurement results.

For example, in one embodiment, the base station selects a beam or a beam combination for the UE according to the signal quality measurement result, where the beam combination can be used for the UE to support at least one data transmission multiplexing mode of time domain multiplexing, frequency domain multiplexing, and spatial domain multiplexing to implement multi-panel joint uplink transmission.

In one embodiment, in selecting a beam, the selected beam may be from the same or different SRS resource set configurations. In order to find a beam that supports joint uplink transmission of multiple panels. For example, the selected beam may be at least one of:

at least one beam for single panel transmission is supported, and the beam combination for at least one multi-panel data transmission multiplexing mode is supported: time domain multiplexing, spatial domain multiplexing, frequency domain multiplexing.

In one embodiment, the measurement result for selecting the beam may be RSRP (reference signal received power) or L1-SINR (signal-to-interference-plus-noise ratio), which can indicate signal quality.

2) Relating to beams and/or beam combinations indicating UE selection

Regardless of the manner in which the base station selects (e.g., based on beam measurement results as previously described and/or based on known beam information), the manner in which to indicate may be employed.

In one embodiment, the configuration information may be implemented in the form of an SRI combination list for either codebook-based uplink transmission or non-codebook based uplink transmission. The base station may configure the SRI combination list through higher layer signaling. This list can be divided into two categories:

a: first SRI Combined List

For example, the SRI combination list may include: at least one SRI code point sequence number (SRI codepoint index), and at least one piece of space relation information (spatialRelationInfo) corresponding to each SRI code point sequence number. As shown in table 1, an example of an SRI combination list is given, for example, a SpatialRelationInfo combination list with an SRI combination length of 8 is configured, where the SRI corresponding to the configuration with the sequence number of 6 is shown as (SpatialRelationInfo 1, SpatialRelationInfo 2).

Table 1 SRI combined list example 1

For the UE, joint uplink transmission of multiple panels can be implemented according to the SRI combination list shown in table 1. For example, if the serial number of the SRI code point corresponds to a spatial relationship information, the UE may perform uplink data transmission on a panel; if the same SRI code point sequence number corresponds to multiple spatial relationship information, the UE may perform uplink data transmission on multiple panels by using at least one combination of time domain multiplexing, frequency domain multiplexing, and spatial domain multiplexing.

B: second type of SRI combined list

For example, such a combined list of SRIs may include: at least one SRI code point serial number and at least one SRS resource corresponding to each SRI code point serial number. As shown in table 2, an example of an SRI combination list is given. Table 2 shows an example of an SRI list, for example, a list with an SRI list length of 8 is configured, where corresponding to the configuration with the serial number of 6, the SRI combinations suitable for common reception are shown as (SRS1, SRS2), that is, SRS beams corresponding to SRS1 and SRS2 are suitable for common reception scheduling of joint transmission.

If the measured result shows that some TRPs cannot meet the reception condition for all SRS reception, only the SRS resource meeting the reception condition is configured, so that the case of only a single SRS may be included. As shown in the configurations of SRI code point numbers 0 and 1 in table 1 and table 3, respectively.

Table 2 SRI list example

SRI codepoint index	Description
		0	SRS1
1	SRS3
		。。。	。。。
6	SRS1，SRS2
		7	SRS3，SRS5，SRS8

After receiving the SRI combination list shown in table 2, the UE may use the SRS resource combination corresponding to the SRI code point sequence number in the SRI combination list to perform uplink data transmission.

If the same code point serial number corresponds to one SRS resource, the UE can perform uplink data transmission on one panel;

if the same code point serial number corresponds to multiple SRS resources, the UE may perform uplink data transmission on multiple panels by using at least one combination of time domain multiplexing, frequency domain multiplexing, and space domain multiplexing.

It should be noted that the base station finds a plurality of beams most suitable for reception according to the beam measurement result, and the beams may be from the same panel or different panels.

In addition to the above two SRI combination lists, the SRI combination list may further include at least one of the following beam information: supporting the beam sent by a single panel and the beam combination corresponding to at least one multi-panel data joint transmission multiplexing mode: time domain multiplexing, spatial domain multiplexing, frequency domain multiplexing.

Further, as described previously, the base station may employ the same SRI combination list configuration method for two UEs supporting codebook-based transmission and non-codebook-based transmission.

Of course, in another embodiment, the base station may also configure different SRI combination lists for UEs with different transmission modes according to the transmission modes supported by the UE. For example, when the UE can report the capability information, it reports whether the UE supports the capability of codebook-based transmission. Then, when the base station determines that the UE supports codebook-based transmission, the same SRI code point sequence number in the SRI combination list configured for the UE may correspond to one or more pieces of spatial relationship information or one or more SRS resources. When the base station determines that the UE supports non-codebook-based transmission, the same SRI code point sequence number in the SRI combination list configured for the UE corresponds to one piece of spatial relationship information or one piece of SRS resource.

Based on the SRI combination list, in order to implement PUSCH transmission for this scheduling, the base station may configure SRS resources and measurement feedback for the UE for uplink CSI.

Base station can configure SRS resource for uplink CSI for UE and implement measurement feedback

There can be two cases, codebook-based transmission and non-codebook-based transmission. In the embodiments of the present application, the following contents are emphasized:

1. codebook-based transmission case:

for codebook-based transmission, after generating configuration information indicating the beam and/or beam combination and transmitting the configuration information to the UE, the base station may receive that the UE transmits a plurality of uplink channel sounding signals through a plurality of panels and performs measurement to obtain an uplink channel quality measurement result; and then, according to the uplink channel quality measurement result, indicating the SRS resource combination used by the terminal for the PUSCH joint transmission of the scheduling.

For example, the base station may manage the resulting beam combinations (SRI combination list 1 and SRI combination category 2 as described earlier) and the multiple multi-port SRS resources for codebook transmission in terms of beams. And then, the UE sends uplink detection signals on respective panel according to the SRS resources configured by the base station. And the base station selects and feeds back the SRI codepoint selected by the base station and the corresponding precoding information to be used for the beam combination of the PUSCH joint transmission of the scheduling by measuring the uplink detection signal. The base station may indicate single panel transmission as shown in index0, index1 above, or may indicate joint transmission of multiple panels as shown in index6, index7 above. For example, when the fed-back SRIs combined into SRI1+ SRI2, then in the sending time corresponding to SRI1, the UE applies the spacial relalationinfo 1 and TPMI1& RI1 of the SRS corresponding to SRI1 to send on the corresponding panel, and applies the spacial relalationinfo 2 and TPMI2& RI2 of the SRS corresponding to SRI2 to send data on the corresponding panel.

2. For the non-codebook based transmission case:

the base station may configure associated downlink reference signal resources NZP CSI-RS to the UE for uplink sounding reference signal resource sets of different panels, respectively. For example, the base station may determine a corresponding TRP/panel combination according to the optimal beam combination of beam management found by the selected beam and/or beam combination (e.g., SRI combination list 1 and SRI combination list 2 described above), and further configure NZP CSI-RS (downlink reference signal) resources associated with each of the plurality of SRS resource sets.
