1. A user equipment (UE), comprising:
radio front end circuitry; and
processor circuitry, coupled to the radio front end circuitry, and configured to:
receive, using the radio front end circuitry, a message from a base station (BS);
based on the received message, determine whether to use a lowest Channel Access Priority Class (CAPC) or a highest CAPC;
in response to a determination to use the lowest CAPC, select a CAPC based on the lowest CAPC of one or more Media Access Control (MAC) Service Data Units (SDUs) that are multiplexed in one or more MAC Protocol Data Units (PDUs) for an uplink (UL) transmission;
in response to a determination to use the highest CAPC, select the CAPC based on the highest CAPC of the one or more MAC SDUs that are multiplexed in the MAC PDU for the UL transmission; and
transmit, using the radio front end circuitry, the MAC PDU to the BS,
wherein the message indicates to use the lowest CAPC in response to an access point (AP) associated with a wireless network being detected, and wherein the AP is associated with the UE or the BS.
