摘要： A UE does not immediately perform handover after receiving a handover command from a serving base station, but instead backups that message and continuously compares the signal strength of a serving base station and the signal strength of a target base station and performs a handover to the target base station at the best timing when handover is required. Once the timing of handover is determined, the UE transmits a handover indication message to the serving base station, and thereafter the UE performs a handover to the target base station.

摘要： A base station infers a random access failure rate depending on a random access collision of terminals performing random access and controls a random access opportunity of a terminal that fails the random access by using the random access failure rate of each terminal. Also, information for the controlled random access opportunity is transmitted to the terminal that fails the random access.

摘要： A base station determines whether a reception of each uplink signal transmitted by a plurality of terminals succeeds. The base station generates a response bit map representing whether the reception succeeds. Further, the base station transmits first downlink control information (DCI) including the response bit map to the plurality of terminals through a first downlink control channel.
