1. A communications device configured to transmit data or receive data, the communications device comprising:
transceiver circuitry configured to transmit signals and receive signals via a wireless access interface, and
controller circuitry configured in combination with the transceiver circuitry:
to receive one or more first control signals each comprising an indication of one of one or more first sets of radio resources of the wireless access interface in each of which the communications device is to receive one of one or more first downlink signals,
to decode the one or more first downlink signals,
to determine that the communications device should transmit a feedback signal indicating, for each of the first downlink signals, whether or not the each of the first downlink signals were successfully received, wherein the communications device is configured to transmit the feedback signal in a second set of radio resources of the wireless access interface indicated by at least one of the first control signals,
to determine that the communications device should transmit an uplink signal in a third set of radio resources of the wireless access interface, the third set of radio resources at least partially overlapping in time with or sharing a same time-divided slot of the wireless access interface with the second set of radio resources,
to determine, in accordance with whether at least one communications criterion is met, whether the communications device should form a multiplexed signal by multiplexing at least a part of the feedback signal into the uplink signal and transmit the multiplexed signal in the third set of radio resources of the wireless access interface, and
to adjust at least one of the uplink signal and the third set of resources such that the at least one communications criterion is met, when the at least one communications criterion is not met.
