A method of operating a communications device in a wireless communications network, the method comprising determining that the communications device should transmit at least two uplink signals to the wireless communications network, wherein the uplink signals are each to be transmitted in a set of uplink resources of a wireless access interface, determining that the set of uplink radio resources in which a first of the uplink signals should be transmitted at least partially overlaps the set of uplink radio resources in which a second of the uplink signals should be transmitted, wherein the first uplink signal has a different one of a plurality of physical layer priority levels to the second uplink signal, and detecting an indication of whether the first uplink signal and the second uplink signal should be multiplexed, wherein, if the indication indicates that the first uplink signal and the second uplink signal should be multiplexed, the method further comprises multiplexing the first uplink signal and the second uplink signal into a third uplink signal, and transmitting the third uplink signal, wherein, if the indication indicates that the first uplink signal and the second uplink signal should not be multiplexed, the method further comprises transmitting only the one of the first uplink signal and the second uplink signal that has a higher physical layer priority level, wherein the indication is explicitly indicated by at least one of a plurality of downlink signals received by the communications device from the wireless communications network, and characterized in that the indication comprises a first dynamic indicator explicitly indicated by a first of the downlink signals on which the first uplink signal is based and a second dynamic indicator explicitly indicated by a second of the downlink signals on which the second uplink signal is based. determining that the communications device should transmit at least two uplink signals to the wireless communications network, wherein the uplink signals are each to be transmitted in a set of uplink resources of a wireless access interface, determining that the set of uplink radio resources in which a first of the uplink signals should be transmitted at least partially overlaps the set of uplink radio resources in which a second of the uplink signals should be transmitted, wherein the first uplink signal has a different one of a plurality of physical layer priority levels to the second uplink signal, and detecting an indication of whether the first uplink signal and the second uplink signal should be multiplexed, wherein, if the indication indicates that the first uplink signal and the second uplink signal should be multiplexed, the method further comprises multiplexing the first uplink signal and the second uplink signal into a third uplink signal, and transmitting the third uplink signal, wherein, if the indication indicates that the first uplink signal and the second uplink signal should not be multiplexed, the method further comprises transmitting only the one of the first uplink signal and the second uplink signal that has a higher physical layer priority level, wherein the indication is explicitly indicated by at least one of a plurality of downlink signals received by the communications device from the wireless communications network, and characterized in that the indication comprises a first dynamic indicator explicitly indicated by a first of the downlink signals on which the first uplink signal is based and a second dynamic indicator explicitly indicated by a second of the downlink signals on which the second uplink signal is based. <EOS>
