Timing Advance Management in Wireless Communications

Abstract

A user equipment (UE) is configured to determine to send an uplink (UL) transmission to a network, determinw a timing advance group (TAG) associated with the UL transmission and transmit the UL transmission based on at least parameters associated with the TAG. A UE is also configured to receive a Physical Random Access Channel (PRACH) configuration for a candidate cell comprising whether the candidate cell supports random access response (RAR) skipping in response to a PRACH, receive a Physical Downlink Control Channel (PDCCH) downlink control information (DCI) order (PDCCH-order DCI) for the UE to trigger a PRACH transmission to the candidate cell and perform a PRACH procedure with the candidate cell according to the PRACH configuration, wherein the PRACH procedure comprises transmitting the PRACH to the candidate cell.
