Embodiment 1

[0068] In this embodiment, the length of the MAC CE signaling sent by the network side device to the user terminal is not fixed.

[0069] This embodiment specifically includes the following steps:

[0070] Step 1: The network side device sends MAC CE signaling to the UE to indicate the spatial relationship of the UE's PUCCH resources. The format of the MAC CE signaling Header (subheader) is as follows image 3 As shown, the MAC CE signaling format is as follows Figure 4 shown.

[0071] In the MAC CE signaling subheader, R is a reserved bit with an initial value of 0. The F field (that is, the above-mentioned length indication) is used to indicate the length of the L field. If the value is "1", it means that the length of the L field is 8 bits, and if the value is "0", it means that the length of the L field is 16 bits. LCID (that is, the type indication of the above-mentioned MAC CE signaling) is used to indicate the type of MAC CE signaling, and here is used to indicate t...

Embodiment 2

[0075] In this embodiment, the length of the MAC CE signaling sent by the network side device is fixed.

[0076] This embodiment specifically includes the following steps:

[0077] Step 1: The network side device sends a MAC CE to the UE to indicate the spatial relationship of the PUCCH resource of the UE. The format of the MAC CE signaling Header is as follows Figure 5 As shown, the MAC CE signaling format is as follows Figure 6 shown.

[0078] In the MAC CE signaling subheader, R is a reserved bit with an initial value of 0. LCID (that is, the type indication of the above-mentioned MAC CE signaling) is used to indicate the type of MAC CE signaling, and here is used to indicate that the corresponding MAC CE signaling is a PUCCH resource space relationship indicating MAC CE.

[0079] In MAC CE signaling, A k (that is, the above-mentioned QCL relationship configuration indicator field) indicates whether to configure the QCL relationship for the PUCCH Resource whose index ...

Embodiment 3

[0083] In this embodiment, the length of the MAC CE signaling sent by the network side device is fixed.

[0084] This embodiment specifically includes the following steps:

[0085] Step 1: The network side device sends a MAC CE to the UE to indicate the spatial relationship of the PUCCH resource of the UE. The format of the MAC CE signaling Header is as follows Figure 7 As shown, the MAC CE signaling format is as follows Figure 8 shown.

[0086] In the MAC CE signaling subheader, R is a reserved bit with an initial value of 0. LCID (that is, the type indication of the above-mentioned MAC CE signaling) is used to indicate the type of MAC CE signaling, and here is used to indicate that the corresponding MAC CE signaling is a PUCCH resource space relationship indicating MAC CE.

[0087] In the MAC CE signaling, there are k QCL relationship identifiers (QCL relationship Command), the size of the QCL relationship Command is 1 byte, arranged in the order of the PUCCH resource c...

Abstract

The invention provides a PUCCH resource indication, a processing method, a network side device, and a user terminal, and belongs to the technical field of communication. Wherein, the PUCCH resource indication method is applied to the network side equipment, including: generating MAC CE signaling according to the PUCCH resource configuration information of the user terminal, the MAC CE signaling indicating the spatial relationship adopted by at least one PUCCH resource of the user terminal; The user terminal sends the MAC CE signaling. Through the technical scheme of the present invention, the spatial relationship of PUCCH resources can be flexibly indicated, thereby effectively reducing signaling overhead.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a PUCCH resource indication, a processing method, a network side device, and a user terminal. Background technique [0002] For signals with the same channel characteristics among different channels, it can be assumed that these signals come from the same transmission source. QCL (Quasi-CoLocation, quasi-co-location) configuration can include a variety of different signal types, such as CSI-RS (Channel State Information-Reference Signal, channel state information-synchronous signal) or SSB (Synchronous Signal Block, synchronous channel signal) . The network side can configure corresponding QCL signals for different beams. The network can change the working beam of the UE (User Equipment, user terminal) by changing the QCL configuration of the UE. [0003] According to the current NR (New Radio, new air interface) conclusion, a MAC CE MAC CE (Medium Access Control...
