OPTIMIZING TIMING ADVANCE DETERMINATION IN UPLINK CHANNEL SYNCHRONIZATION

摘要

Described herein are various aspects related to optimizing timing advance (TA) determination in uplink channel synchronization. For example, a plurality of access requests can be transmitted according to a TA using power ramping. It can be determined that a maximum transmit power is achieved by one of the plurality of access requests, and in this case, a TA training sequence can be transmitted comprising another plurality of access requests at varying TAs using a maximum transmit power based on determining that the maximum transmit power is achieved. Further, if no response is received to the another plurality of access requests, a trial sequence can be transmitted comprising a third plurality of access requests according to the TA using a maximum transmit power.
