Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
1 . A mobile terminal arranged to transmit uplink data to a network over a radio interface using a plurality of sub-carriers, the network being arranged to receive uplink data transmitted from mobile terminals of a first type and mobile terminals of a second type, the mobile terminal being a mobile terminal of the second type, the mobile terminals of the first type being arranged to transmit uplink data on a first group of sub-carriers of the plurality of sub-carriers over a first bandwidth and the mobile terminal is arranged to transmit uplink data on a second group of sub-carriers of the plurality of sub-carriers within the first group of sub-carriers over a second bandwidth, the second bandwidth being smaller than the first bandwidth, and the mobile terminal is arranged to transmit a random access request message to a base station of the network requesting uplink radio resources on a random access channel, wherein the mobile terminal transmits random access request messages on the random access channel on sub-carriers within the second group of sub-carriers. 2 . A mobile terminal arranged to transmit uplink data to a network over a radio interface using a plurality of sub-carriers, the network being arranged to receive uplink data transmitted from mobile terminals of a first type and mobile terminals of a second type, the mobile terminal being a mobile terminal of the second type, the mobile terminals of the first type being arranged to transmit uplink data on a first group of sub-carriers of the plurality of sub-carriers over a first bandwidth and the mobile terminal is arranged to transmit uplink data on a second group of sub-carriers of the plurality of sub-carriers within the first group of sub-carriers over a second bandwidth, the second bandwidth being smaller than the first bandwidth, and the mobile terminal is arranged to transmit a random access request message to a base station of the network requesting uplink radio resources on a random access channel, wherein the mobile terminal transmits random access request messages on the random access channel on sub-carriers outside of the second group of sub-carriers but within the remaining sub-carriers of the first group of sub-carriers.
