Abstract: A method is presented for performing a device-to-device (D2D) operation by a first user equipment (UE) in a wireless communication system. The first UE receives configuration information of an evolved-universal mobile telecommunications service (UMTS) terrestrial radio access network (E-UTRAN) planned mode for the D2D operation from an evolved NodeB (eNB). The E-UTRAN planned mode is a D2D mode in which the eNB controls radio resources for the D2D operation. The UE performs the D2D operation with a second UE by using the radio resources in the E-UTRAN planned mode.

Abstract: A method and apparatus for configuring a proximity-based services (ProSe) scheduling request (SR) prohibit timer in a wireless communication system is provided. A user equipment (UE) receives an indication of the ProSe SR prohibit timer from a network, and configures the ProSe SR prohibit timer according to the indication. Upon configuring the ProSe SR prohibit timer, the UE may start or stop the configured ProSe SR prohibit timer for a triggered ProSe BSR which may only correspond to a Regular ProSe BSR. If the ProSe BSR has been triggered and the ProSe SR prohibit timer is not running, the UE may trigger a SR.

Abstract: A method and apparatus for indicating a logged multimedia broadcast multicast service (MBMS) measurement availability in a wireless communication system is provided. A user equipment (UE) determines whether to inform a serving cell that the UE has logged MBMS measurement results to be reported based on a first condition and a second condition, and when both the first condition and the second condition are met, the UE informs the serving cell that the UE has the logged MBMS measurement results. The first condition corresponds to that the UE has the logged MBMS measurement results to be reported. The second condition includes at least one MBMS minimization of drive tests (MDT) related condition.
