METHOD AND APPARATUS FOR AVOIDING PHYSICAL RANDOM ACCESS CHANNEL COLLISIONS

摘要

A method and apparatus for avoiding Physical Random Access Channel collisions is provided. The method may comprise transmitting, by a first user equipment (UE), a first access request using a synchronization code in a subframe to a Node B, and receiving an acknowledgement from the Node B, wherein the acknowledgement indicates that a second UE has transmitted a second access request in the subframe using the synchronization code. Further, the method may comprise receiving, in a subframe, a first synchronization code from a first UE and a second synchronization code from a second UE, and preventing transmission of an acknowledgment to both the first and second UEs based on a determination that the received first and second synchronization codes are the same.
