Abstract
The technology described herein is directed towards advancing a user equipment's initial access PRACH (physical random access channel) transmission message based on the distance between the user equipment and the base station so that the message is received within the detection window time interval of the base station (e.g., gNodeB). The timing advance can be determined based on the estimated detection window time interval's midpoint to increase the probability of the transmitted PRACH message being successfully detected by the base station. In one alternative, for unsuccessful detection the timing advance data can be modified for one or more PRACH message transmission reattempts, e.g., by multiples of the detection window time interval. In another alternative, for unsuccessful detection based on the transmitted preamble identifier not equaling the base station's returned preamble identifier, the timing advance can be increased or decreased based on the transmitted preamble identifier and the returned preamble identifier.
