WIPO Patent Application WO/2021/243675

A1

A method of wireless communication includes receiving, by a user equipment (UE) from a serving cell, a first timing advance command (TAC) associated with a first antenna panel of the UE and with a first timing advance group (TAG). The method further includes, in response to receiving the first TAC, initiating operation of a timer of the UE. The method further includes, during operation of the timer, receiving, by the UE from the serving cell, a second TAC associated with a second antenna panel of the UE and with a second TAG. The method further includes determining, based on the second TAC indicating the second TAG, whether to reset the timer.
