Abstract
Some aspects relate to apparatuses and methods for a wireless system supporting two timing advances in a serving cell for a user equipment (UE) communicating with two different transmission reception points (TRPs). The UE can determine that a first timing advance (TA) group (TAG) and a second TAG are configured for a serving cell based on a configuration received from the base station; and further determine a first TA adjustment value based on a first timing advance command (TAC) and a second TA adjustment value based on a second TAC. The UE can select a TAC from the first TAC or the second TAC to be applied to an uplink transmission. The UE can further select, based the selected TAC, a TAG from the first TAG or the second TAG; and transmit the uplink transmission according to the selected TAC with the selected TAG.
