Abstract
A system and method to optimize the number of uplink and downlink slots, given the maximum number of crossed slots between any two cells is disclosed. The present invention effectively assigns a direction (i.e. uplink or downlink) to every slot in every cell of the system, taking into account the trade-off between: a) avoiding base-to-base or mobile-to-mobile interference; and b) matching the slot assignment of every cell as closely as possible to the local traffic conditions. The present invention assigns users to slots according to their transmission power requirements in order to allow conflicting slot-to-cell assignments between two cells in the same geographic region.
Claims5
A system to optimize a plurality of slots in a communications system in which a maximum number of crossed slots exists between a plurality of cells, comprising:
- means to assign a direction to each slot in each cell of the system in which base-to-base interference is reduced;
- and
- wherein slot assignments for each cell relate to communication traffic conditions.
