METHODS AND DEVICES FOR RANDOM ACCESS PREAMBLE SHIFTING

摘要

A method implemented in a user equipment (UE) for adjusting for propagation delay includes transmitting one or more preamble sequence sequences to a network node. The method further includes recording a response result for each preamble sequence transmitted to the network node. The method includes analyzing each response result to determine whether a propagation delay condition exists. If the propagation delay condition exists, the method includes adjusting a timing of a preamble sequence transmission in accordance with a time shift or monitoring for a preamble sequence in accordance with the time shift.
