Claim:
1. A method for performing, by a first user equipment (UE), a buffer status reporting (BSR) in a wireless communication system, the method comprising: receiving a configuration of an evolved-UMTS terrestrial radio access network (E-UTRAN) planned mode in which an eNodeB (eNB) controls radio resources for UE-to-UE transmission from the eNB; generating, in the E-UTRAN planned mode, a first type of BSR for uplink transmission from the first UE to the eNB and a second type of BSR for UE-to-UE transmission from the first UE to a second UE; and transmitting the first type of BSR and the second type of BSR via a media access control (MAC) protocol data unit (PDU) to the eNB, wherein the type of the BSR is indicated by a header of the MAC PDU, and wherein a MAC control element (CE) in the MAC PDU includes an indication of the second UE.
