1. Circuitry for a communications device, the circuitry comprising:
transceiver circuitry; and
controller circuitry configured in combination with the transceiver circuitry to:
receive, from infrastructure equipment in a wireless communications system, a scheduling message comprising an indication of an allocation of radio resources to be used for a random access procedure message for a random access procedure supported by the wireless communications system;
select a transport block size (TBS) from a plurality of permitted TBS values for transmission of the random access procedure message, wherein each permitted TBS value of the plurality of permitted TBS values is associated with a repetition number, the repetition number being a maximum number of times that the random access procedure message can be transmitted in the allocated radio resources for the each permitted TBS value of the plurality of permitted TBS values;
determine whether the selected TBS is lower than a maximum TBS of the plurality of permitted TBS values; and
in a case that the selected TBS is determined to be lower than the maximum TBS:
select, based on an identifier of the communications device, a starting transmission time for starting transmission of the random access procedure message from a set of one or more permitted starting transmission times associated with the selected TBS; and
transmit the random access procedure message to the infrastructure equipment in the allocated radio resources using the selected TBS at the selected starting transmission time.
