Abstract
A user equipment (UE) and a method of uplink beam management are provided. The method includes being configured, by a source cell, an uplink transmit beam for an uplink transmission for a target cell and transmitting, to the target cell, the configured uplink transmit beam for the uplink transmission. During a handover from the source cell to the target cell, the uplink transmit beam for the UE to the target cell is determined based on collaboration between the source cell and the target cell. The method enables a random access channel-free (RACH-free) handover procedure which reduces latency of handover and overhead of signaling and resource.
