Abstract
A method for reducing cross cell interference in a wireless time division duplex communication system using code division multiple access, the system having at least one user equipment (UE) and a base station (BS) is disclosed. The method begins by measuring an interference level of each timeslot at the BS. A timeslot is eliminated for additional uplink communication if the measured interference level exceeds a first threshold. UEs in nearby cells that are large interferers are identified and their downlink timeslot usage is gathered. A timeslot is eliminated for uplink communication for a large interferer UE that uses the timeslot for downlink communication.

A method for reducing cross cell interference in wireless communications, comprising:
- measuring an interference level of each timeslot at a base station (BS);
- eliminating a timeslot for additional uplink communication if the measured interference level exceeds a first threshold;
- identifying user equipments (UEs) in cells near a particular UE that are large interferers;
- gathering downlink timeslot usage for large interferer UEs;
- and
- eliminating a timeslot for uplink communication for a large interferer UE that uses the timeslot for downlink communication.
