Abstract: A method and apparatus for determining a multimedia broadcast multicast service (MBMS) interest in a wireless communication system is provided. A user equipment (UE) configures an MBMS threshold, and determines an MBMS interest by comparing a measurement result with the configured MBMS threshold. Only if the measurement result is higher than the configured MBMS threshold the UE determines a frequency, which corresponds to the MBMS interest, to be part of MBMS frequencies of interest.

Abstract: The present invention relates to a method of transmitting, by a base station, a signal for compensating for coverage in a wireless communication system, and an apparatus therefor. A method of transmitting, by a base station, a signal for compensating for coverage, comprises: receiving information indicating that a first base station is a base station supporting a multimedia broadcast/multicast service (MBMS), from the first base station in a state enabling switching off; receiving a coverage compensation request message containing MBMS-related information of the first base station from the first base station; and transmitting, by a compensation base station to the first base station, a coverage compensation response message indicating whether it is possible to compensate for the coverage of the first base station, wherein whether it is possible to compensate for the coverage of the first base station is determined on the basis of the MBMS-related information.

Abstract: A method and apparatus for performing a random access procedure in a wireless communication system is provided. A user equipment (UE) determines one random access configuration from a first random access configuration for a normal type of UE and a second random access configuration for a specific type of UE, and transmits a random access preamble based on the second random access configuration to an eNodeB (eNB) if the UE is a specific type of UE. Also, a method and apparatus for establishing, by a UE, a connection in a wireless communication system is provided. The UE transmits a connection request message including bandwidth related information to the eNB.

Abstract: A method and apparatus for configuring a buffer status report (BSR) for a public safety transmission or a vehicle-related (V2X) transmission in a wireless communication system is provided. A user equipment (UE) configures a device-to-device (D2D) logical channel corresponding to the public safety transmission or the V2X transmission, and triggers a proximity-based services (ProSe) BSR for the D2D logical channel. The UE accommodates the triggered ProSe BSR in a media access control (MAC) protocol data unit (PDU) if the MAC PDU can accommodate only one BSR MAC control element (CE).
