Communications device, infrastructure equipment and methods

A communications device for transmitting and/or receiving data operating according to a Half Duplex Frequency Division Duplex mode of operation (HD-FDD) in a wireless communications network, the communications device comprising

• receiver circuitry configured to receive signals from the wireless communications network transmitted via a downlink channel of a wireless access interface provided by the wireless communications network,
• transmitter circuitry configured to transmit signals to the wireless communications network via an uplink channel of the wireless access interface, and
• controller circuitry configured to control the receiver circuitry
• to receive a first format indicator for the uplink channel of the wireless access interface provided by the wireless communications network for transmitting uplink data to the wireless communications network,
• to receive a second format indicator for the downlink channel of the wireless access interface provided by the wireless communications network for receiving downlink data from the wireless communications network,
• to receive, 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;
• to receive 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;
• and the controller circuitry is configured
• to determine that one or more of the first physical resources of the uplink channel and one or more of the second physical resources of the downlink channel overlap in time;
• to determine, on a basis of the first format indicator for the uplink channel and the second format indicator for the downlink channel, 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, and the second format indicator defines a format for each of the physical resources of the downlink channel.
