1. An infrastructure equipment forming part of a wireless communications network, the infrastructure equipment, comprising:
transceiver circuitry configured to transmit signals and to receive signals via a wireless access interface provided by the wireless communications network, and
controller circuitry configured to control the transceiver circuitry to
transmit an explicit uplink hybrid automatic repeat request acknowledgement indicator, e-HARQ indicator, to a communications device,
wherein the e-HARQ indicator indicates to the communications device whether or not the communications device should monitor for a first HARQ acknowledgement, HARQ-ACK, in a specific time slot and in a specific frequency resource of the wireless access interface, the first HARQ-ACK being transmitted by the infrastructure equipment in response to an uplink transmission from the communications device to the infrastructure equipment,
wherein the specific time slot in which the communications device should monitor for the first HARQ-ACK is one of a plurality of consecutive time slots forming a time window.
