METHOD AND AN APPARATUS OF ADJUSTING TRANSMISSION TIMING, CAPABLE OF EFFECTIVELY CONTROL THE TRANSMISSION TIMING OF UPLINK TIMING IN RELAY SYSTEM

摘要

PURPOSE: A method and an apparatus of adjusting transmission timing are provided to effectively control the transmission timing of uplink signal in a wireless communication system.;CONSTITUTION: An apparatus receives a first uplink timing adjustment value from relay. The apparatus receives a second uplink timing adjustment value through the random access response. The apparatus controls the transmission timing of the uplink signal using the values. The first uplink timing adjustment value is based on the timing adjustment value obtaining between relay and base station in the random access process.;COPYRIGHT KIPO 2011
