Claim 17:
18. Circuitry for an infrastructure equipment for use with a wireless telecommunications system, the infrastructure equipment comprising transceiver circuitry and controller circuitry, wherein:
the controller circuitry is configured:
to control the transceiver circuitry to attempt to transmit a first signal to a terminal device of the wireless telecommunications system during one or more of a plurality of predetermined time periods, wherein the attempting to transmit a first signal during the one or more of the plurality of predetermined time periods is carried out in response to transmitting one or more second signals to the terminal device indicating that the one or more of the plurality of predetermined time periods should be used for the attempted reception of a first signal; and
to control the transceiver circuitry to receive a third signal from the terminal device, the third signal indicating a number of second signals received by the terminal device; and
compare the number of second signals transmitted by the infrastructure equipment with the number of second signals received by the terminal device as indicated by the third signal in order to determine whether there is a discrepancy in the number of second signals transmitted by the infrastructure equipment and the number of second signals received by the terminal device.
