Abstract:
A method for allocating radio channels in a time division multiple access time frame which contains asymmetric downlink and uplink traffic channel fields, said method comprising the steps of:dividing the asymmetric downlink and uplink traffic channel fields into a number of regions, wherein each region has associated with it an expected level of intercell interference, wherein the asymmetric downlink and uplink traffic channel fields together are divided into a total of three regions, and wherein a first region coincides only with the downlink traffic channel field, a second region coincides only with the uplink traffic channel field, and a third region coincides with a portion of the downlink traffic channel field and a portion of the uplink traffic channel field;determining a level of susceptibility to intercell interference for each of a plurality of mobile units; andselecting the third region and assigning a radio channel in the third region to the one mobile unit, if it is determined that the one mobile unit has a low level of susceptibility to intercell interference, wherein the expected level of intercell interference associated with the third region is greater than the expected level of intercell interference associated with the first and the second regions.
