A method of transmitting data by a communications device to a wireless communications network, the method comprising receiving (S600, S602) by the communications device 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, wherein the indication of the communications resources received by the communications device for transmitting the uplink data is one of a configured grant of semi-statically configured resources or a dynamic grant of communications resources provided by a downlink control information message providing an uplink grant, determining, by the communications device, 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 transmitting, by the commonications device, 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. receiving (S600, S602) by the communications device 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, wherein the indication of the communications resources received by the communications device for transmitting the uplink data is one of a configured grant of semi-statically configured resources or a dynamic grant of communications resources provided by a downlink control information message providing an uplink grant, determining, by the communications device, 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 transmitting, by the commonications device, 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.
