Detailed Description

Before the technical solution of the embodiment of the present invention is introduced, a description is given of a related art.

In the related art, in R17, RAN1#103e determines to support that the MAC CE may activate at most 2 uplink beams (spatial relationship info) for 1 PUCCH resource (resource) for uplink transmission in the FR2 band. RAN1#104b-e determines that 1 PUCCH resource can be associated with 1 or 2 sets of Power Control (PC) parameters, and the PC parameters may be designed according to the SpatialRelationInfo structure, except that the referrals signal is removed.

In the R17, FR1 is supported, 2 sets of power control parameter sets are indicated for PUCCH resources by using MAC CEs, where the set is composed of p0, path RS ID and closed-loop index, and is used for Multi-transmit-receive point (Multi-TRP) transmission, if R15 is used, one MAC CE needs to be sent for each PUCCH resource separately to indicate its power control parameter, and the overhead on signaling is too large.

In R15, the base station may configure a maximum of 128 PUCCH resources for the terminal, may configure a maximum of 8 uplink beams (PUCCH-spatial relationship info) by RRC, and may activate one of them for each PUCCH resource by the MAC CE, at each fractional BandWidth (BWP, bandWidth Part) of each serving cell (serving cell).

In R15, the design of each PUCCH resource individually activated beam is not flexible, which means that at most 128 individual MAC-CEs need to be transmitted to complete beam updating for 128 PUCCH resources. R16 divides PUCCH resources of 1 BWP into N groups, and simultaneously activates a group of beams of PUCCH resources with 1 MAC CE. The PUCCH resources grouped in the same group use the same beam. By the method, only N MAC-CEs are needed to be activated for all the beams of the PUCCH resources in one BWP, and signaling overhead and time delay are greatly reduced. The PUCCH resource grouping is configured through RRC, the MAC CE activates a single PUCCH resource beam in the grouping, and the PUCCH resource belonging to the same grouping with the PUCCH resource is updated and uses the same beam at the same time.

In the existing PUCCH resource grouping scheme for beam activation, since RRC signaling can configure 8 uplink beams at most, the number of packets should not exceed 8, and R16 finally selects 4 as the maximum number of PUCCCH packets for beam activation. Meanwhile, activated beams of the PUCCH resources in the existing packet are the same, but due to factors such as interference suppression and different PUCCH formats, optimal power control parameters corresponding to the PUCCH resources in the same packet may not be the same. Therefore, the existing PUCCH resource grouping method for beam activation is not suitable for supporting the PUCCH power control parameter set indication based on grouping, and a new grouping scheme needs to be designed for the PUCCH resource power control parameter set indication.

Based on this, in the embodiment of the present invention, the MAC CE sent by the network device is received; the MAC CE carries first information; the first information is used for indicating a power control parameter set corresponding to PUCCH resources in at least one PUCCH resource group of the terminal.

Fig. 1 is a schematic diagram of an implementation flow of an information indication method according to an embodiment of the present invention, and is applied to a terminal, and as shown in fig. 1, the method includes step 101:

It is understood that the set of power control parameters may refer to a set consisting of p0, pathloss RS ID, and closed-loop index.

In an embodiment, the method further comprises:

wherein, N and M are positive integers.

Further, the configuration information of the N PUCCH Resource groups and the configuration information of the M power Control parameter sets, which are sent by the network device, may be received through Radio Resource Control (RRC).

It is noted that N may be less than or equal to M; alternatively, N may be greater than M.

In practical application, it is considered that a single PUCCH resource may correspond to at least one set of power control parameter set, and the PUCCH resource belongs to at least one PUCCH resource group, so that the MAC CE may indicate the power control parameter set of the PUCCH resource in the at least one PUCCH resource group.

In practical application, considering that a certain single PUCCH resource for Multi-TRP may correspond to multiple sets of power control parameter sets, and the PUCCH resource belongs to at least two PUCCH resource groups, so that the power control parameter set of the PUCCH resource may be indicated by the MAC CE, and one PUCCH resource group of the at least two PUCCH resource groups to which the PUCCH resource belongs may be indicated.

In an embodiment, the target PUCCH resource corresponds to multiple sets of power control parameter sets; the target PUCCH resource belongs to at least two PUCCH resource groups; the first information also represents one PUCCH resource group in at least two PUCCH resource groups to which the target PUCCH resource belongs; the method further comprises the following steps:

It can be understood that, after receiving the MAC CE, the terminal determines the power control parameter set corresponding to the target PUCCH resource and one PUCCH resource set of the at least two PUCCH resource sets to which the target PUCCH resource belongs, and updates the power control parameter sets of other PUCCH resources in the indicated one PUCCH resource set, so as to ensure that one PUCCH resource set of the at least two PUCCH resource sets to which the target PUCCH resource belongs uses the same power control parameter set.

In actual application, the power control parameter set of one PUCCH resource group may be indicated by the MAC CE.

Based on this, in an embodiment, the first information characterizes a second correspondence relationship between a target PUCCH resource group and a power control parameter set; the method further comprises the following steps:

and according to the power control parameter set corresponding to the target PUCCH resource group, setting the power control parameters of all PUCCH resources in the target PUCCH resource group.
