Abstract: A method and apparatus for establishing a device-to-device (D2D) connection in a wireless communication system is provided. A first device may establish the D2D connection with a second device. The first device only knows information on neighbor devices of the first device, and a network does not know the information on neighbor devices of the first device. The first device determines whether to establish the D2D connection with the second device or not, based on at least one of a proximity between the first device and the second device based on a profile of the second device obtained through a neighbor discovery procedure, a presence of data to be transmitted to the second device, and a preference for the D2D connection of the first device.

Abstract: In the present disclosure, a UE transmits a random access preamble (RAP) on a physical random access channel (PRACH) and a control channel (CCCH) service data unit (SDU) on a physical uplink shared channel (PUSCH); and receives a medium access control (MAC) protocol data unit (PDU) based on transmitting the RAP and the CCCH SDU. The MAC PDU includes a MAC subheader. The MAC subheader includes a first indicator field regarding whether the MAC subheader include an RAP identity (ID) or not. The MAC subheader further includes a second indicator field regarding whether the MAC subheader includes a backoff indicator field or not, based on the first indicator field set to a value indicating that the MAC subheader does not include an RAP ID.
