Title: POWER BASED CONTENTION RESOLUTION DURING A RANDOM ACCESS PROCEDURE
Abstract:
Technology for a first user equipment (UE) operable to perform power based contention resolution between the first UE and a second UE during a random access procedure is disclosed. The first UE can signal a first random access channel (RACH) message for transmission to a base station. The first UE can decode a random access response (RAR) message received from the base station. The first UE can determine an aggregated channel gain for the first UE and the second UE using power based contention resolution information included in the RAR message. The first UE can compare a ratio of the channel gain for the first UE and the aggregated channel gain relative to a defined threshold. The first UE can determine when to continue the random access procedure for the first UE based on a comparison of the ratio to the defined threshold.
