Abstract:
Various embodiments include methods for managing uplink timing advance configuration of wireless devices by a base station. A wireless device may send an initial access signal to a base station, receive from the base station an initial timing advance value responsive to the initial access signal, and send to the base station a next signal comprising a Physical Random Access Channel (PRACH) waveform via uplink (UL) receive (Rx) points over two or more beams. The base station may receive the next signal including the PRACH waveform via the two or more UL Rx points, select a refined timing advance value based on the signal, and send the refined timing advance value to the wireless device. The wireless device may receive the refined timing advance value and send a further signal to the base station via one of the UL Rx points using the refined timing advance.
