Wireless communications system and method in a wireless communications system

A method in a wireless device having a reduced data bandwidth, the method comprising:

• receiving control and data signalling transmitted by a wireless base station within a first bandwidth in respective control and data regions, the control signalling being received by the wireless device within the first bandwidth, and the data signalling being received by the wireless device within a second bandwidth which is narrower than the first bandwidth;
• receiving a first control message within the control region, the first control message comprising location information of a second control message within the data region;
• receiving the second control message which comprises scheduling information of a third control message within the data region;
• and
• receiving the third control message which comprises information identifying resources allocated by the wireless base station for use by wireless devices having the reduced bandwidth.

A wireless base station for communicating with a wireless device having a reduced data bandwidth or a reduced control and data bandwidth, the wireless base station comprising:

• a transmitter to transmit control and data signalling within a first bandwidth, in respective control and data regions, wherein signalling within the data region intended for the wireless device is constrained within a second bandwidth which is narrower than the first bandwidth, and
• a communications processor configured to:
• transmit, to the wireless device, a first control message within the control region, the first control message comprising location information of a second control message within the data region;
• transmit, to the wireless device, the second control message which comprises scheduling information of a third control message within the data region;
• and
• transmit, to the wireless device, the third control message which comprises information identifying resources allocated by the wireless base station for use by wireless devices having the reduced bandwidth.

A wireless user equipment (UE) having a reduced data bandwidth, the wireless UE comprising:

• a receiver to receive control and data signalling transmitted by a wireless base station within a first bandwidth in respective control and data regions, the control signalling being received by the wireless device within the first bandwidth, and the data signalling being received by the wireless device within a second bandwidth which is narrower than the first bandwidth, and
• a communications processor configured to:
• receive a first control message within the control region, the first control message comprising location information of a second control message within the data region;
• receive the second control message which comprises scheduling information of a third control message within the data region;
• and
• receive the third control message which comprises information identifying resources allocated by the wireless base station for use by wireless devices having the reduced bandwidth.

A method implemented in a wireless communications system, the method comprising:

• transmitting, from a wireless base station to a wireless device having a reduced data bandwidth or a reduced control and data bandwidth, control and data signalling within a first bandwidth, in respective control and data regions, wherein signalling within the data region intended for the wireless device is constrained within a second bandwidth which is narrower than the first bandwidth;
• transmitting, from the wireless base station to the wireless device, a first control message within the control region, the first control message comprising location information of a second control message within the data region;
• transmitting, from the wireless base station to the wireless device, the second control message which comprises scheduling information of a third control message within the data region;
• and
• transmitting, from the wireless base station to the wireless device, the third control message which comprises information identifying resources allocated by the wireless base station for use by wireless devices having the reduced bandwidth.
