1. An infrastructure equipment for forming part of a mobile radio network, the infrastructure equipment comprising:
circuitry including at least a transceiver and a processor, the circuitry configured to:
transmit and receive data to and from associated mobile communications devices via a wireless access interface; and
process requests for communications resources from the associated mobile communications devices, wherein
each associated mobile communications device, of a plurality of associated mobile communications devices of a group, is assigned a same common identifier with respect to which communications sessions can be established to communicate data via the mobile radio network, and
the circuitry is further configured to transmit a signaling message, in response to a request from a single associated mobile communications device of the plurality of associated mobile communications devices of the group, to the single associated mobile communications device to establish a communications bearer using the common identifier, and
the communications bearer is for downlink communication by all associated mobile communications devices of the group and for uplink communication only by the single associated mobile communications device of the group, the single associated mobile communications device having an allocated time to access the communications bearer to perform a non-contention based random access procedure, the communications bearer comprising a physical random access channel (PRACH).
