Abstract:
A method (700) of operation in a cellular communication system including at least one base station and, associated with the at least one base station, a plurality of user terminals in sectors to allow separate communications between the base station and the user terminals in different sectors, the method including providing (701, 703) a set of communication resource slots for distribution to the sectors for use in sending uplink traffic data, dividing (705, 707) at least part of the set into groups of slots having equal numbers of resource slots and allocating (709, 711) the groups of slots to the different sectors. A system, a base station and a mobile station operable using the method are also described.
Abstract:
A mobile station (107, 200) for use in a cellular communication system (100) includes a processor (214) operable to determine whether the mobile station should undergo cell re-selection by handover from a first base station (101) to a second base station (102), wherein the determination includes comparing a value of a property (RSSI) of a signal received from the second base station with a value of the same property of a signal received from the first base station and calculating whether the difference between the two values is greater than a pre-determined reference difference (SRH), characterised in that the processor is operable to apply in the difference calculation a reference difference (SRH(0), SRH(1)..) which varies as a function of time during an idle mode of operation of the mobile station.
Abstract:
A method of operation in a communication system is presented in which a first terminal sends to a second terminal a communication including ranging information by which the second terminal is able to calculate a range between the first terminal and the second terminal. The communication is sent in a plurality of frames. In at least one of the frames ranging information is included in a ranging region of the frame. The size and position of the ranging region is known to the first and second terminals without a ranging information indicator being sent in the frame to indicate the size and position of the ranging region.

Abstract:
A communication system (100) includes a first terminal (105) sending to a second terminal (101) a communication including ranging information by which the second terminal is able to calculate a range between the first terminal and the second terminal. The communication is sent in a plurality of frames (400) and in at least one of the plurality of frames, ranging information is included in a ranging region (431) of the frame and the size and position of the ranging region is known to the first and second terminals without a ranging information indicator being sent in the frame to indicate the size and position of the ranging region. As the ranging information indicator is not included in every frame, this allows more data to be transmitted.

Also disclosed is a system and method incorporating the mobile station.
Abstract:
A method (500) of operation in a communication system (100) including a first terminal (105) sending to a second terminal (101) a communication including ranging information by which the second terminal is able to calculate a range between the first terminal and the second terminal, wherein the communication is sent in a plurality of frames (400) and in at least one of the plurality of frames ranging information is included in a ranging region (431) of the frame and the size and position of the ranging region is known to the first and second terminals without a ranging information indicator being sent in the frame to indicate the size and position of the ranging region. Also described is a system (100), a base station (101) and a mobile station (105) which employ the method.
