1. A method performed by a first wireless device in a wireless communication system, the method comprising,
receiving, from a network, a sidelink (SL) buffer status reporting (BSR) configuration;
triggering a first SL BSR, based on first SL data becoming available for a first logical channel related to a first destination, wherein the first logical channel is related to a first PC5-Radio Resource Control (RRC) connection between a pair of a source and the first destination;
triggering a second SL BSR, based on second SL data becoming available for a second logical channel related to a second destination, wherein the second logical channel is related to a second PC5-RRC connection between a pair of the source and the second destination;
detecting a failure on a sidelink associated with the first destination;
canceling one or more SL BSRs only associated with the first PC5-RRC connection based on the failure on the sidelink associated with the first destination, wherein the first SL BSR is included in the canceled one or more SL BSRs; and
transmitting, to the network, the second SL BSR based on that the second SL BSR has been triggered and not canceled.
