Title:
SUPPLEMENTARY UPLINK CONFIGURATION UPDATE FOR SERVING CELL SET
Document Type and Number:
WIPO Patent Application WO/2022/000475
Kind Code:
A1
Abstract:
A base station may use a media access control (MAC) message to update an uplink configuration for a user equipment (UE) that is configured with a cell set including multiple cells, which may or may not be configured with a supplementary uplink. The UE may receive a configuration of a cell set in which one or more cells are configured with supplementary uplink. The UE may receive a MAC message identifying a cell in the cell set and including a supplementary uplink update field, at least one sounding reference signal (SRS) resource identifier (ID) field, and at least one resource ID field indicating a spatial relation. The UE may determine whether to update a spatial relation for the SRS resource configured for each cell in the cell set based on the MAC message.
