Title:
METHODS AND APPARATUS FOR UPDATING PUCCH SPATIAL RELATION INFORMATION
Document Type and Number:
WIPO Patent Application WO/2021/142831
Kind Code:
A1
Abstract:
The present disclosure relates to methods and devices for wireless communication including a UE and a base station. The UE can receive a MAC CE indicating an update to a spatial relation configuration of the UE for PUCCH transmissions. In some aspects, the update can be indicated by PUCCH resource information, where the PUCCH resource information can include first PUCCH resource information including a first PUCCH resource ID that identifies a first PUCCH resource and first spatial identification information. Additionally, the UE can update the spatial relation configuration of the UE based on at least one of the first PUCCH resource information or other PUCCH resource information of the PUCCH resource information, where the other PUCCH resource information can be in a same PUCCH resource group as the first PUCCH resource. Also, the UE can transmit a PUCCH transmission based on the updated spatial relation configuration.
