The first UE transmits a joint scheduling request and a joint buffer status report (BSR) for an uplink transmission on the Uu link with the base station and a sidelink transmission on the sidelink with the second UE. The joint BSR is associated with a relative latency of the uplink transmission and the sidelink transmission. The first UE receives from the base station, a joint transmission grant scheduling the uplink transmission on a first set of resources and scheduling the sidelink transmission on a second set of resources. The first UE transmits a first transmission on the first set of resources for the uplink transmission and a second transmission on the second set of resources for the sidelink transmission. ## Claims ### Claim 1 A method of wireless communication, comprising at a user equipment (UE): transmitting a joint scheduling request and a joint buffer status report (BSR) for an uplink transmission on a Uu link with a base station and a sidelink transmission on a sidelink with another UE, wherein the joint BSR is associated with a relative latency of the uplink transmission and the sidelink transmission;
