Title:
METHOD AND APPARATUS FOR L1/L2-BASED INTER-CELL MOBILITY
Document Type and Number:
WIPO Patent Application WO/2023/075423
Kind Code:
A1
Abstract:
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Methods and apparatuses for L1/L2 mobility control in a wireless communication system. A method of a UE comprises receiving, from a BS, a message including L1/L2 mobility configuration information. The method includes measuring, based on a CSI-RS received from at least one candidate cell of candidate BS, L1-reference signal received power (L1-RSRP), L1-reference signal received quality (L1-RSRQ), and L1-signal to interference and noise ratio (L1-SINR) of the at least one candidate cell. The method includes reporting the L1-RSRP, the L1-RSRQ, and the L1-SINR of the at least one candidate cell. The method further includes receiving an L1/L2 signal to trigger a handover (HO) operation to the target cell, wherein the L1/L2 signal includes a transmission configuration indicator (TCI) state switch to the target cell.
