Abstract:
1. A method of implementing a timing advance during an uplink communication between a user equipment (UE) and a base station of a wireless network, the method comprising: selecting at least one subframe that is scheduled for pre-transmission processing, wherein, in the pre-transmission processing, payload data within each subframe to be transmitted from the UE to the base station are processed prior to being transmitted via the uplink communication; reducing a duration of the at least one subframe by a value of the timing advance to generate at least one reduced duration subframe; replacing at least a portion of the payload data in the at least one reduced duration subframe with a pre-selected replacement value; withholding pre-transmission processing of the at least a portion of the payload data replaced with the pre-selected replacement value; performing pre-transmission processing of any remaining portion of the at least one subframe, wherein a processing time of the remaining portion of the at least one subframe is reduced by at least the value of the timing advance; and transmitting the at least one reduced duration subframe via the uplink communication to the base station.
