1. A method comprising:
receiving, from a network, information for a sidelink (SL) prioritization threshold;
triggering a first buffer status report (BSR) and a second BSR, wherein the first BSR is a SL-BSR used to provide the network with information about SL data volume and the second BSR is a BSR used to provide the network with information about uplink (UL) data volume;
based on a value of the highest priority of logical channels that belong to any logical channel group (LCG) and contain SL data for any destination being lower than the SL prioritization threshold, prioritizing the LCG(s) for the destination(s);
prioritizing the first BSR containing buffer status for the LCG(s) that are prioritized, over the second BSR;
creating a first media access control (MAC) protocol data unit (PDU) comprising at least the prioritized first BSR;
transmitting the first MAC PDU comprising at least the prioritized first BSR in uplink;
obtaining an SL grant; and
transmitting a second MAC PDU comprising the SL data in sidelink based on the SL grant.
