19. An infrastructure equipment for forming part of a wireless communications network, comprising:
receiver circuitry configured to receive signals transmitted via a wireless access interface formed by the wireless communications network from one or more communications devices,
transmitter circuitry configured to transmit signals via the wireless access interface to the one or more communications devices, and
controller circuitry configured to control the transmitter circuitry
to transmit reference signals via the wireless access interface,
to transmit downlink control information (DCI) via the wireless access interface to one or more communications devices which form a group of communications devices, the DCI indicating whether each of the respective communications devices of the group is to transmit a channel measurement report (CMR), and the controller circuitry is configured to control the receiver circuitry
to receive, in response to the transmitted DCI, a channel measurement report from the one or more of the communications devices of the group, the channel measurement reports being received from communications resources of the wireless access interface determined from the transmitted DCI,
wherein the DCI transmitted by the infrastructure equipment to the group of communications devices is a group common downlink control information (GC-DCI) comprising a plurality of indication fields, each of the plurality of indication fields indicating whether a corresponding one the communications devices in the group of communication devices is requested to transmit a channel measurement report.
