  • Patent number: 7280501
    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 multiplex 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).

  • Publication number: 20030235185
    Abstract: A method of assigning an access mechanism for the transmission of data comprises classifying a plurality of components of the data and assigning these individually to a particular access mechanism according to the suitability of the access mechanism in relation to a particular parameter or set of parameters of the data component by which it is clasified.
