Abstract:
1. A method for receiving a broadcast/multicast service (MBMS) in a wireless communication system, the method performed by a user equipment (UE) and comprising: receiving a first message transmitted to count a number of UEs attempting to receive the MBMS; transmitting a preamble for a random access process for the MBMS; receiving a second message including uplink radio resource allocation information in response to the preamble; transmitting a third message using the uplink radio resource allocation information, the third message including a UE identifier of the UE; receiving a contention resolution message in response to the third message; stopping the random access process when the contention resolution message includes the UE identifier of the UE, wherein the contention resolution message including the UE identifier of the UE indicates an ACK (acknowledgement) for the third message; and stopping the random access process when the contention resolution message does not include the UE identifier of the UE, wherein the contention resolution message not including the UE identifier of the UE indicates an NACK (negative acknowledgement) for the third message.
