1. A method of a communications device operating according to a Half Duplex Frequency Division Duplex mode of operation (HD-FDD) in a wireless communications network, the method comprising:
receiving a first format indicator for an uplink channel of a wireless access interface provided by the wireless communications network for transmitting uplink data to the wireless communications network on a first frequency band,
receiving a second format indicator for a downlink channel of the wireless access interface provided by the wireless communications network for receiving downlink data from the wireless communications network on a second frequency band different from the first frequency band,
receiving, by the communications device, from the wireless communications network a first allocation of first physical resources allocated from physical resources of the uplink channel for transmitting uplink data to the wireless communications network on the first frequency band;
receiving from the wireless communications network a second allocation of second physical resources allocated from physical resources of the downlink channel for receiving downlink data from the wireless communications network on the second frequency band different from the first frequency band;
determining that one or more of the first physical resources of the uplink channel on the first frequency band and one or more of the second physical resources of the downlink channel on the second frequency band different from the first frequency band overlap in time;
determining, on a basis of the first format indicator for the uplink channel on the first frequency band and the second format indicator for the downlink channel on the second frequency band different from the first frequency band, a use of each of the one or more first physical resources and the one or more second physical resources which overlap in time, wherein
the first format indicator defines a format for each of the physical resources of the uplink channel on the first frequency band, and
the second format indicator defines a format for each of the physical resources of the downlink channel on the second frequency band different from the first frequency band.
