Method and system for computing the optimal slot to cell assignment in cellular systems employing time division
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.
