  • Publication number: 20220183031
    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.
