Claim of US Patent No. 11,032,864

1. A method of a first device handling radio link failure, comprising:performing or establishing sidelink unicast communication with a second device, wherein the first device uses a Sidelink Medium Access Control (MAC) entity for the sidelink unicast communication with the second device;
performing or establishing sidelink unicast communication with a third device, wherein the first device uses the Sidelink MAC entity for the sidelink unicast communication with the third device;
detecting a radio link failure associated with the second device;
cancelling pending Scheduling Requests (SRs) and/or Buffer Status Reports (BSRs) associated with the second device in response to the radio link failure, and not cancelling pending SR and/or BSRs associated with the third device in response to the radio link failure; and
flushing soft buffer associated with the sidelink unicast communication with the second device in response to the radio link failure, and not flushing soft buffer associated with the sidelink unicast communication with the third device in response to the radio link failure.
