UPLINK TIMING ADJUSTMENT FOR WIRELESS COMMUNICATION

摘要

A user equipment (UE) applies an uplink timing adjustment during a high speed data call to allow uplink transmission of different UEs to arrive at a base station at a particular estimated time. In one instance, the UE determines whether a downlink (DL) timing varies more than a predetermined amount within a specified time period. The UE applies a timing advance command received in response to a scheduling request when the timing varies more than the predetermined amount. The UE also ignores a current uplink timing based on a closed loop timing advance command

1. A method of wireless communication, comprising:
determining whether a downlink (DL) timing varies more than a predetermined amount within a specified time period; and applying a timing advance command received in response to a scheduling request when the timing varies more than the predetermined amount, and ignoring a current uplink timing based at least in part on a closed loop timing advance command.
