Patent Description:
Beam management includes processes such as beam measurement, beam reporting, beam indication, and so on. Network side configures the setting information of the beam reporting (i.e., reporting setting) for UE through high-level signaling, which includes the content information of the beam reporting, the time-domain related messages of the beam reporting (which may be periodic, aperiodic, semi-persistent), and the frequency granularity information of the beam reporting, etc. The content information of the beam reporting may include: at least one optimal transmitting beam identification information selected by the UE, and physical layer measurement result of the beam selected by the UE (such as Layer <NUM>-reference signal received power (L1-RSRP)), grouping information of the beam selected by the UE, etc..

For signals with the same channel characteristics in different channels, it can be assumed that these signals are from the same source. Spatial relationship (Quasi-collocation(QCL)) configuration may include a variety of different signal types (for example, Channel State Information-Reference Signal (CSI-RS) or Synchronous Signal Block (SS block)). The network side can configure corresponding QCL signals for different beams. The network side can change the beam with which the UE works by changing the QCL configuration of the UE.

When the UE receives a Physical Uplink Control Channel (PUCCH) resource, it faces problems as follows: does it immediately use the PUCCH resource? If yes, what spatial relationship does it correspond to at this time? If not, what will be used to indicate the spatial relationship of the PUCCH resource before using the PUCCH resource? These problems have not been solved.

<NPL>, as to issues on beam measurement and reporting, some proposals have been raised, including: PUCCH beam indication is introduced by RRC signaling; introduce one RRC parameter: PUCCH-Spatial-relation-info; information associating an SSB ID or, a CRI, or a SRI.

<NPL>, proposed that, NR supports that the following QCL assumptions: DMRS of PUCCH/PUSCH is QCLed with an SS block w. spatial QCL parameter; SRS is QCLed with a SS block w. spatial QCL parameter; DMRS of PUCCH/PUSCH is QCLed with a CSI-RS w. spatial QCL parameter; SRS is QCLed with a CSI-RS w. spatial QCL parameter.

In order to explain the technical solutions of the embodiments of the present disclosure more clearly, the following will briefly introduce the drawings required in the description of the embodiments of the present disclosure. Obviously, the drawings in the following description are only some embodiments of the present disclosure. For those of ordinary skill in the art, other drawings can also be obtained based on these drawings without paying any creative effort.

Hereinafter, the technical solutions in the embodiments of the present disclosure will be described clearly and thoroughly in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, but not all of the embodiments.

<FIG> is a first schematic flowchart of a spatial relationship determination method according to an embodiment of the present disclosure. As shown in <FIG>, the spatial relationship determination method, which is applied to a terminal, includes:.

Wherein, the number of the PUCCH resource is associated with a target byte in the MAC CE, each bit in the target byte corresponds to a QCL, and only one bit in the target byte has a preset value.

In the embodiment of the present disclosure, a number ID of each PUCCH resource is determined according to the number of the PUCCHs configured currently through the Radio Resource Control (RRC) message. For example, if the PUCCH resource is the first PUCCH resource configured by the base station, the number of the PUCCH resource is <NUM>, and corresponds to the first byte in the MAC CE. If the PUCCH resource is the nth PUCCH resource configured by the base station, the number of the PUCCH resource is n, and corresponds to the nth byte in the MAC CE.

The above target QCL may be a QCL relationship corresponding to a target bit in the target byte of the MAC CE of the media access control layer control element (MAC CE), or may be a synchronization signal block (SSB) used by the terminal when initially accessing a cell or a PUSCH resource corresponding to the PUCCH resource. The predefined QCL is a QCL configured in advance by the base station or agreed by a protocol.

The method including receiving the physical uplink control channel (PUCCH) resource sent by the base station; and determining the target QCL required when using the PUCCH resource according to the predefined spatial relationship QCL or according to the downlink media access control layer control element (MAC CE) sent by the base station solves the problem of how to determine the QCL required when using the PUCCH resource if the terminal is newly configured a PUCCH resource. Moreover, the method of the present disclosure can flexibly change the QCL required when using the PUCCH resource, thus having a higher flexibility in the spatial relationship configuration of resources.

Further, in the above step <NUM>, the step of determining the target QCL required when using the PUCCH resource according to the downlink media access control layer control element (MAC CE) sent by the base station includes:.

Here, after receiving the downlink media access control layer control element (MAC CE), the terminal determines the QCL relationship corresponding to the target bit in the target byte of the downlink MAC CE as the target QCL, and starts to use this PUCCH resource according to the target QCL.

Specifically, if the target QCL is received at Nth subframe, the PUCCH resource is started to be used at (N+t)th subframe, where N is a positive integer, and t is a natural number; t may be configured by the physical layer, or may be agreed by a protocol; t may be in units of subframes, or in units of symbols or ms.

In this implementation, the number ID of each PUCCH resource is determined according to the number of the PUCCHs configured according to the radio resource control (RRC) message. For example, the ID of the first PUCCH resource configured through the RRC message is <NUM>, and the ID of the configured nth PUCCH resource is n. Each resource ID is associated with one byte in the MAC CE. As shown in <FIG>, when the ID of a PUCCH resource is <NUM>, the byte associated with it is byte <NUM> (Oct <NUM>); when the ID of a PUCCH resource is n, the byte associated with it is byte n (Oct n). As shown in <FIG>, each byte in the MAC CE includes <NUM> bits, and each bit corresponds to one QCL. For example, when Ri is set to <NUM>, this means the ith QCL is adopted. In a PUCCH resource, at most one QCL relationship is selected. Thus, only one of the <NUM> bits is set to <NUM>.

The spatial relationship corresponding to each bit may be configured using the RRC message, such as <NUM> spatial relationships QCL1. Then the resource ID of a certain PUCCH resource indicates which spatial relationship is adopted. For example, if the resource ID of the current PUCCH resource is <NUM>, a bit set to <NUM> is selected from the sixth byte of the MAC CE, and the QCL corresponding to the bit is used as the target QCL.

Here, the target QCL is determined through the downlink MAC CE sent by the base station, thus saving signaling overhead.

Further, in the above step <NUM>, the step of determining the target QCL required when using the PUCCH resource according to the predefined spatial relationship QCL includes:.

The PUSCH corresponding to the PUCCH configuration resource refers to a PUSCH located in a same bandwidth part (BWP) or in a same carrier component (CC) as the PUCCH configuration resource.

Here, after receiving the PUCCH resource configuration information sent by the base station, the terminal first determines the synchronization signal block or the PUSCH corresponding to the PUCCH resource indicated by the PUCCH resource configuration information as the target QCL, and then starts to use the PUCCH resource according to the synchronization signal block or the PUSCH; when receiving the downlink MAC CE, it changes the target QCL to the QCL corresponding to the target bit in the target byte of the downlink MAC CE.

The above synchronization signal block is a synchronization signal block at the initial access of the terminal. In this implementation, once the UE is newly configured with a PUCCH resource, it uses the synchronization signal block or PUSCH resource at the initial access as the target QCL to start using the PUCCH resource, and after receiving a DL MAC CE, changes the target QCL corresponding to the PUCCH resource.

In this implementation, the format of the downlink MAC CE is the same as the format of the MAC CE in the above implementation, and will not be repeated here.

Further, in the above step <NUM>, the step of determining the target QCL required when using the PUCCH configuration resource according to the predefined spatial relationship QCL includes:.

Specifically, the above predefined QCL may be configured in advance by the base station, e.g., the RRC configures the first QCL among multiple QCLs of this PUCCH resource as the predefined QCL; alternatively, a QCL with the smallest or largest index among multiple QCLs is configured as the predefined QCL by the agreement of a protocol.

In this implementation, when receiving the PUCCH resource configuration information sent by the base station, the terminal determines the predefined QCL as the target QCL at first, and starts to use the above PUCCH resource according to the predefined QCL; when receiving the downlink MAC CE, it changes the target QCL to the QCL corresponding to the target bit in the target byte of the downlink MAC CE, thus solving the problem of how to determine the QCL required when using the PUCCH resource if the terminal is newly configured a PUCCH resource. Moreover, the method of the present disclosure can flexibly change the QCL required when using the PUCCH resource, thus having a higher flexibility in the spatial relationship configuration of resources.

The spatial relationship determination method according to the embodiment of the present disclosure includes: receiving the physical uplink control channel (PUCCH) resource configuration information sent by the base station, the PUCCH resource configuration information indicating a PUCCH resource; determining the target QCL required when using the PUCCH resource according to the predefined spatial relationship QCL or according to the downlink media access control layer control element (MAC CE) sent by the base station, thereby solving the problem of how to determine the QCL required when using the PUCCH resource if the terminal is newly configured a PUCCH resource; moreover, the method of the present disclosure can flexibly change the QCL required when using the PUCCH resource, thus having a higher flexibility in the spatial relationship configuration of resources.

As shown in <FIG>, an embodiment of the present disclosure further provides a spatial relationship determination method applied to a base station, which includes:.

Wherein, a number of the PUCCH resource is associated with a target byte in the MAC CE, each bit in the target byte corresponds to a QCL, and only one bit in the target byte has a preset value.

The base station sends the downlink MAC CE to the terminal so that the terminal determines the target QCL required when using the PUCCH resource according to the downlink MAC CE, thereby solving the problem of how to determine the QCL required when using the PUCCH resource if the terminal is newly configured a PUCCH resource; moreover, the method of the present disclosure can flexibly change the QCL required when using the PUCCH resource, thus having a higher flexibility in the spatial relationship configuration of resources.

Further, before the above step <NUM>, the method further includes:
configuring for the terminal a target QCL required when using the PUCCH resource.

Specifically, the above predefined QCL may be configured in advance by the base station, e.g., the RRC configures the first QCL among multiple QCLs of this PUCCH resource as the predefined QCL; alternatively, a QCL with the smallest or largest index among multiple QCLs is configures as the predefined QCL.

The base station configures the target QCL required when using the PUCCH resource through the RRC in advance, so that the terminal uses the PUCCH resource according to the configured target QCL when receiving the PUCCH resource.

The format of the downlink MAC CE is the same as the format of the MAC CE in the above method embodiment applied to a terminal, and will not be repeated here.

In the above implementation, the target QCL is determined according to the downlink MAC CE, thus saving signaling overhead.
