13. A communication method performed by a communication apparatus comprising:
transmitting to a base station a direct link BSR, wherein the direct link Buffer Status Report (BSR) is a message that informs the base station of an amount of D2D data to be transmitted from the communication apparatus to a destination user equipment; and
receiving from the base station a D2D grant that schedules D2D resources for the D2D data;
wherein the direct link BSR has a lower or higher priority in resource scheduling than an uplink BSR, the uplink BSR being a message that informs the base station of an amount of uplink data to be transmitted from the communication apparatus to the base station, and
wherein the direct link BSR has a higher priority in resource scheduling than data from any logical channel, except data from Uplink Common Control Channel (UL-CCCH).
