Abstract: The embodiments herein relate to methods for SL SR/BSR handling. In one embodiment, there proposes a method in a wireless device, comprising: triggering a Sidelink (SL) Buffer Status Report (BSR) in response to data to be sent over the SL; triggering a Sidelink (SL) Scheduling Request (SR) for transmitting the SL BSR, wherein the SL BSR is intended to be transmitted by using a first uplink (UL) grant triggered by the SL SR; and cancelling the SL SR transmission if the SL BSR has been transmitted by using a second UL grant triggered by other sources. With embodiments herein, the LCP can be adapted based on QoS requirement and unsuitable cancel of sidelink BSR can be avoided, which improves performance of both UL and sidelink.

Abstract: A method is disclosed for operating a user equipment (UE) for device-to-device (D2D) communications. The method includes receiving booking information from another UE. The booking information identifying a resource that the other UE is booking to use for transmission by the other UE and further including priority information. The method further includes selectively transmitting preemption signaling based on whether the received priority information indicates lower priority than local priority information that is associated with a transmission to be scheduled by the UE. The preemption signaling indicates preemption of the UE to use the resource identified by the booking information. The method further includes scheduling the UE to transmit using the resource identified by the booking information.
