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: The present invention relates to a communication between MAC layer entity and PHY layer entity for parallel random access procedures of dual connectivity. In this scheme, a first PHY entity of a user equipment informs a failure of a random access preamble transmission to a first MAC entity of the UE. Then, the first MAC entity continues or stops a random access procedure without performing procedures for a random access failure.

Abstract: A method and apparatus for configuring a cell in a wireless communication system is provided. A user equipment (UE) receives a radio resource control (RRC) message which includes a configuration for a secondary cell (SCell) and an indication of an initial state of the SCell. The initial state of the SCell is set to either one of an activated state and deactivated state. The UE configures the SCell based on the configuration and the initial state of the SCell.
