Title:
METHODS AND APPARATUSES FOR MAINTAINING TA VALUES
Document Type and Number:
WIPO Patent Application WO/2024/082498
Kind Code:
A1
Abstract:
Embodiments of the present application relate to methods and apparatuses for maintaining timing advance (TA) values under a 3rd Generation Partnership Project (3GPP) 5G system or the like. According to an embodiment of the present application, a centralized unit (CU) includes a transceiver and a processor coupled to the transceiver, and the processor is configured to: transmit a request for cell switching including identifier (ID) information of one or more candidate cells via the transceiver to one or more candidate distributed units (DU) s of the BS; receive radio resource control (RRC) configuration information for the one or more candidate cells via the transceiver from the one or more candidate DUs; and transmit an RRC reconfiguration message associated with the one or more candidate cells via the transceiver to a user equipment (UE).
