CHANNEL ALLOCATION IN A TELECOMMUNICATIONS SYSTEM WITH ASYMMETRIC UPLINK AND DOWNLINK TRAFFIC

摘要

In a synchronous cellular radio telecommunicationsnetwork that employs a time division multiple access (TDMA)channel allocation scheme, an effective approach toallocating channels or time slots in a TDMA time framecontaining asymmetric downlink and uplink traffic channelfields can be achieved by dividing the downlink and uplinktraffic channel fields into a number of regions, based onan expected level of intercell interference associated witheach region. In addition, the level of susceptibility tointercell interference for each mobile unit operating in agiven cell is continuously established. The allocation ofchannels or time slots is then carried out for each of themobile units based on, among other things, the level ofsusceptibility associated with each of the mobile units,the level of expected intercell interference associatedwith each of the regions, and whether the channel or timeslot is being allocated for the purpose of conveyinginformation in the uplink or downlink traffic channelfield.
