Communications devices, infrastructure equipment, and methods

An infrastructure equipment of a wireless communications network configured to transmit data to or receive data from a communications device, the infrastructure equipment comprising

• transceiver circuitry configured to transmit signals and receive signals via a wireless access interface provided by the wireless communications network, and
• controller circuitry configured in combination with the transceiver circuitry
• to transmit, to the communications device, in one of a plurality of sets of radio resources each forming a physical downlink control channel, PDDCH, in a first time divided slot of the wireless access interface, one of an uplink grant indicating an allocation of radio resources forming a physical uplink shared channel, PUSCH, of the wireless access interface and a downlink grant indicating an allocation of radio resources forming a physical downlink shared channel, PDSCH, of the wireless access interface, and
• to transmit, to the communications device, an indication of an index of a look-up table associated with a value of a first parameter in the look-up table,
• wherein, if a specified condition has been met, the value of the first parameter indicates a number of symbols between a specified point associated with the PDCCH in which the one of the uplink grant and the downlink grant was received and a first symbol of the one of the PUSCH and the PDSCH, or if the specified condition has not been met, value of the first parameter indicates a number of symbols between the start of the first time divided slot and a first symbol of the one of the PUSCH and the PDSCH.
