ABSTRACT:
Resource units are assigned within a cell of a wireless time division duplex communication system using code division multiple access. Each resource units is associated with a time slot and a code. For selected ones of the cell's resource units, the code interference level is measured during that unit's time slot and using that unit's code. The code interference level is compared to a threshold to determine whether that unit has an acceptable code interference level. Resource units are assigned to communications out of the unit's having acceptable interference levels.
