Patent ID: 8369209

Claim:
A method for processing a collision between a random access procedure and a measurement gap, the method comprising the steps, carried out during the measurement gap, of: configuring, by a base station, a measurement gap to a terminal for conducting an inter-frequency or an inter-RAT measurement; performing, by the terminal, a random access procedure for accessing a network or synchronizing with the network and acquiring resource allocation, wherein the random access procedure is a contention-based random access procedure, and comprises the steps of: transmitting, by the terminal, a random access preamble through an uplink random access channel (RACH) to the base station; monitoring, by the terminal, the Physical Downlink Control Channel (PDCCH) for a random access response message transmitted from the base station during a random access response window; transmitting, by the terminal, a scheduled transmission message on an Uplink-Shared Channel (UL-SCH), and activating a contention resolution timer after transmitting the scheduled transmission message; and monitoring, by the terminal, the Physical Downlink Control Channel (PDCCH) for a contention resolution message transmitted from the base station; canceling, by the terminal, the measurement gap if the random access response window or the operating time of the contention resolution timer has an overlap with the measurement gap.
