Indication of transmission priority class is disclosed for sharing a base station's maximum channel occupancy time (MCOT) for use in autonomous uplink (AUL). Aspects of the disclosure provide for implicitly sharing the MCOT by providing an indication of transmission opportunity (TxOP) length. A serving base station sends an indication of a current TxOP length in control signals to a user equipment (UE). The UE may then infer a set of potential transmission priorities used by the serving base station according to the TxOP length, as TxOP length may relate to the MCOT, which itself may be associated with a particular transmission priority class. The UE may then, conservatively, select the highest transmission priority of the set of potential transmission priorities for autonomously transmitting any uplink data having at least the selected highest transmission priority within configured AUL resource of the current TxOP.

The method comprises: a terminal determining a priority order of logical channels on which a Uu interface and a sidelink interface trigger the sending of a Buffer Status reporting (BSR); and the terminal sending the BSR according to the priority order of the logical channels on which the Uu interface and the sidelink interface trigger the sending of the BSR.

The method may comprise a step of comparing, on the basis that multiple sidelink transmissions and uplink transmission are overlapped in a time domain, a first priority related to the multiple sidelink transmissions and a second priority related to the uplink transmission, wherein the first priority is the highest priority among priorities respectively related to the multiple sidelink transmissions, and preferentially assigning transmit power to transmission related to a higher priority among the first priority and the second priority.

A method and apparatus for triggering of transmission carrier or resource reselection in a wireless communication system is provided. A first wireless device reserves a set of resources comprising at least a first resource and a second resource for sidelink transmission. When (i) the sidelink transmission using the first resource overlaps with an uplink transmission, and (ii) a priority of the uplink transmission is higher than a threshold, the first wireless device clears the first resource from the set of resources, and adds a third resource to the set of resources.
