Abstract: A method of allocating timeslots between uplink and downlink communication in a cellular communication system (10) is described. The method comprises: for consecutive time division multiple access, TDMA, frames comprising the timeslots, allocating a first selection of the timeslots to uplink communication in each of a plurality of cells (101,201) and allocating a second selection of the timeslots to downlink communiction in each of the plurality of cells (101,201); and, when the number of timeslots of each frame to be allocated to uplink communication rather than downlink is different for different cells (101,201), varying the allocation of at least some of the uplink and downlink timeslots in a random or pseudo-random sequence in each cell (101, 201).

Abstract: A radiotelephone method includes detecting other mobile stations and identifying possible relay candidates among the other mobile stations. The method then includes communicating information about the candidates to a base station. Communication with a second mobile station is requested of the base station at a first mobile station. If the first mobile station and the second mobile station are physically close, the base station instructs the first mobile station and the second mobile station to establish direct communication.

Abstract: This invention relates to an apparatus and method for allocating timeslots subscriber units in a time division duplex communication system (300). The communication system (300) has a number of frame synchronised base stations (301). The apparatus (301) comprises a switching point processor (323) which determines a switching point (223) between uplink and downlink timeslots in a time frame. It further comprises a power level processor 321 which determines power levels associated with communication from aplurality of subscriber units (307, 309, 311) to be allocated time slots. In addition the apparatus (301) comprises a time slots scheduler which allocates time slots in the time frame to the subscriber units (307, 309, 311) in response to the associated power levels. The invention is applicable to 3rd generation cellular communication systems such as the Time Division Duplex mode of UMTS.

Abstract: A method of, and apparatus for, controlling data packets routed via a packet control means (14) comprising a buffer (16) to a subscriber unit (34) in a cellular communications system (1). The method comprises determining a probability of an interruption in a communication route between the packet control means (14) and the subscriber unit (34); and dependent upon the probability, performing a packet control process for reducing the number of data packets in the buffer (16). The step of performing the packet control process may be further dependent upon the number of data packets in the buffer (16). The packet control process may comprise deleting data packets from the buffer (16) and/or providing for the rate or number of data packets being sent to the buffer (16) to be reduced. The interruption may be due to the subscriber unit (34) being handed over between cells of the cellular communications system (1).
