摘要： A mobile telecommunications system including mobile terminals of first type and second type configured to transmit uplink data to a network over a radio interface using plural sub-carriers. The mobile terminals of first type configured to transmit uplink data on a first group of the sub-carriers over a first bandwidth and the mobile terminals of second type configured to transmit uplink data on a second group of the sub-carriers within the first group of sub-carrier over a second bandwidth smaller than the first bandwidth. The mobile terminals of first type transmit random access request messages to a base station of the network requesting uplink radio resources on a first random access channel. The mobile terminals of second type transmit random access request messages to the base station of the network requesting uplink radio resources on a second random access channel on sub-carriers within the second sub-carrier group.

摘要： A method of allocating transmission resources in an OFDM wireless telecommunication system arranged to communicate data using a plurality of OFDM sub-carriers. The method comprises allocating transmission resources provided by a first group of the plurality of OFDM sub-carriers within a first frequency band to terminals of a first type; allocating transmission resources provided by a second group of the plurality of OFDM sub-carriers within a second frequency band to terminals of a second type, the second group being smaller than the first group and the second frequency band being selected from within the first frequency band; transmitting control information comprising resource allocation information for terminals of the first type over a first bandwidth corresponding to the combined first and second groups of OFDM sub-carriers; and then transmitting control information comprising resource allocation information for terminals of the second type over a second bandwidth corresponding to the second group of OFDM sub-carriers.

摘要： A mobile telecommunications system including mobile terminals of first type and second type configured to transmit uplink data to a network over a radio interface using plural sub-carriers. The mobile terminals of first type configured to transmit uplink data on a first group of the sub-carriers over a first bandwidth and the mobile terminals of second type configured to transmit uplink data on a second group of the sub-carriers within the first group of sub-carrier over a second bandwidth smaller than the first bandwidth. The mobile terminals of first type transmit random access request messages to a base station of the network requesting uplink radio resources on a first random access channel. The mobile terminals of second type transmit random access request messages to the base station of the network requesting uplink radio resources on a second random access channel on sub-carriers within the second sub-carrier group.
