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.
Claims8
A wireless network device comprising:
- a resource allocation device configured to schedule user equipments (UEs) using a plurality of resources;
- wherein the resource allocation device is further configured to receive an indication for each of the plurality of resources for a neighboring wireless network device;
- each indication having one of two values;
- wherein a first of the two values indicates a small interference and a second of the two values indicates a large interference;
- and
- wherein the resource allocation device schedules UEs in response to the received indications.
