A mobile terminal comprising a processor and a receiver configured to receive data from a wireless communications system via a wireless access interface, the mobile terminal belonging to a predetermined group of mobile terminals, the wireless access interface providing a plurality of communications resource elements across a first frequency range, wherein the wireless access interface includes a plurality of time divided sub-frames, and at least one of the sub-frames includes: a first control region in a first part of the sub-frame for communicating first signalling information to one or more of the mobile terminals, the first control region including a plurality of control channel resource elements, a first subset of said control channel resource elements providing a group control channel, the group control channel being associated with a group identifier and at least partially encoded using the group identifier, wherein the group identifier is a RNTI and the encoding of the group control channel is the encoding of CRC bits using the RNTI; and a second control region in a second part of the sub-frame, distinct from the first part of the sub-frame, the second control region being for communicating second signalling information to a predetermined group of the mobile terminals, and wherein the group control channel contains information indicative of the location of the second control region, said information being accessible by applying the group identifier to the group control channel, wherein membership of the predetermined group is indicated by the use of a shared group identifier, wherein the processor operates to locate the group control channel within the first control region using the shared group identifier, wherein the group identifier is deduced from a relationship between a first preamble signature indicated in a random access preamble message received by a base station from a terminal and a second preamble signature indicated in a random access response message transmitted by the base station to the terminal in reply to the random access preamble message, the random access response message including a reserved RNTI where a cell RNTI is expected, and wherein the group identifier is determined by the terminal to be the reserved RNTI by virtue of the presence of the reserved RNTI in the random access response message. a first control region in a first part of the sub-frame for communicating first signalling information to one or more of the mobile terminals, the first control region including a plurality of control channel resource elements, a first subset of said control channel resource elements providing a group control channel, the group control channel being associated with a group identifier and at least partially encoded using the group identifier, wherein the group identifier is a RNTI and the encoding of the group control channel is the encoding of CRC bits using the RNTI; and a second control region in a second part of the sub-frame, distinct from the first part of the sub-frame, the second control region being for communicating second signalling information to a predetermined group of the mobile terminals, and wherein the group control channel contains information indicative of the location of the second control region, said information being accessible by applying the group identifier to the group control channel, wherein membership of the predetermined group is indicated by the use of a shared group identifier, wherein the processor operates to locate the group control channel within the first control region using the shared group identifier, wherein the group identifier is deduced from a relationship between a first preamble signature indicated in a random access preamble message received by a base station from a terminal and a second preamble signature indicated in a random access response message transmitted by the base station to the terminal in reply to the random access preamble message, the random access response message including a reserved RNTI where a cell RNTI is expected, and wherein the group identifier is determined by the terminal to be the reserved RNTI by virtue of the presence of the reserved RNTI in the random access response message.
