Title:
IMPLICITLY UPDATING TIMING ADVANCE IN L1/L2 MOBILITY
Document Type and Number:
WIPO Patent Application WO/2024/026806
Kind Code:
A1
Abstract:
Aspects presented herein may improve the latency and efficiency of L1/L2 inter-cell mobility by providing an improved TA management for a UE. In one aspect, a UE derives a TA for a set of deactivated cells based on an Rx time difference between an active cell and the set of deactivated cells. The UE maintains the TA for the set of deactivated cells prior to an activation of the set of deactivated cells. The UE applies the TA to the set of deactivated cells or to an initial Tx to the set of deactivated cells in response to the activation of the set of deactivated cells. The set of deactivated cells may correspond to one deactivated cell or a deactivated TAG that includes multiple deactivated cells.
