Classification: CPC H | IPC H

Claim 17:
18. Circuitry for an infrastructure equipment forming part of a fifth generation New Radio (5G NR) wireless communications network comprising:
transceiver circuitry configured to transmit signals to and to receive signals from communications devices via a wireless access interface provided by the 5G NR wireless communications network, and
controller circuitry configured in combination with the transceiver circuitry
to receive feedback information from each of the communications devices as at least some of the received signals on configured resources according to Multimedia Broadcast and Multicast Services (MBMS) from the infrastructure equipment
to determine a delay time for each of a plurality of communications devices, the delay time being a one-way- time taken for the each of the communications devices to receive the signals transmitted by the infrastructure equipment, and the delay time for each of the communications devices is determined in accordance with the feedback information received from the communications devices,
to set a playback time dependent on a longest of the delay times among the plurality of communications devices, the playback time being a time at which one or more of the communications devices should transmit a signal, and
to transmit the signals to each of the communications devices, the signals comprising an indication of the playback time for the communication devices to transmit at least one downlink packet from the infrastructure equipment at a same time.
