Ofdm based wireless communication using flexible resources

A communications device configured to transmit uplink data to a wireless communications network, the communications device comprising

• transmitter circuitry configured to transmit signals representing the uplink data via a wireless access interface provided by the wireless communications network,
• receiver circuitry configured to receive signals from the wireless access interface, and
• controller circuitry configured to control the transmitter circuitry and the receiver circuitry
• to receiving an indication of communications resources in one or more of the time-slots of a wireless access interface provided by the wireless communications network for transmitting the uplink data, the time-slots each including communications resources comprising a plurality of Orthogonal Frequency Division Multiplexing, OFDM, symbols designated as either uplink symbols for the communications device to transmit uplink data, downlink symbols in which an infrastructure equipment can transmit signals and the communications device cannot transmit the uplink data or flexible symbols which can be configured as either designated as uplink symbols or downlink symbols,
• to determine from the indication of the communications resources, OFDM symbols of the one or more time-slots which are designated for transmitting the uplink data, and
• to transmit the uplink data in the OFDM symbols determined as designated for uplink transmission, wherein the determining the OFDM symbols of the one or more time slots which are designated for transmitting uplink data includes identifying one or more of the flexible symbols of the one or more time-slots which can be used for transmitting the uplink data based on information received in the indication of the communications resources for transmitting the uplink data.
