Claim of US Patent No. 10,993,253

1. A base station comprising:a receiver, which, in operation, receives from a communication apparatus a direct link Buffer Status Report (BSR) for a device to device (D2D) communication, wherein the direct link 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
a transmitter, which, in operation, transmits to the communication apparatus a D2D grant that schedules D2D resources for the D2D data,
wherein the direct link BSR has a lower 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).
