Adaptive uplink/downlink timeslot assignment in a hybrid wireless time division multiple access/code division multiple access communication system

摘要

A method and apparatus for adaptive uplink/downlink resource assignment may include determining uplink interference associated with each of several uplink resources. A wireless network device may produce an uplink list with values for the uplink resources. The device may compare a downlink power level to at least one threshold for each of the downlink resources, wherein at least two of the downlink resources are each associated with a different portion of a frame. The device may produce a downlink list, which may be a bit stream providing an indication, for each downlink resource, indicating whether each of the downlink resources have a downlink power level which is less than or equal to the at least one threshold. The device may send the uplink and downlink lists and may receive an uplink list and a downlink list from each of several neighboring wireless network devices.

主权项

1. A wireless network device comprising:
a resource assignment processor configured to determine an uplink interference associated with each of a plurality of uplink resources and produce a first uplink list having one of a plurality of values for each of the plurality of uplink resources; the resource assignment processor further configured to compare a downlink power level to at least one threshold for each of a plurality of downlink resources, wherein at least two of the downlink resources are each associated with a different portion of a frame, and produce a first downlink list, wherein the first downlink list is a bit string providing at least one indication for each of the downlink resources, wherein each indication indicates whether the downlink power level for each downlink resource is less than or equal to the at least one threshold; a transceiver operatively coupled to the resource assignment processor, the transceiver configured to send the first uplink list and the first downlink list; the transceiver further configured to receive a second uplink list and a second downlink list from each of a plurality of neighboring wireless network devices; and the resource assignment processor further configured to schedule uplink resources and downlink resources to a user equipment based on the received second uplink list and the received second downlink list.
