System and method for mobile station-assisted interference mitigation

摘要

Devices and methods are provided for using a mobile station to mitigate interference between wireless access points. A mobile station communicates interference mitigation data corresponding to a first and second set of radio resources between a first and second wireless access point (AP). The interference mitigation data is processed by the first wireless AP to resolve conflicts in the claiming, and subsequent assignment, of the first and second radio resource assignments to the mobile station.

主权项

1. A system for mitigating interference between a first wireless access point (AP) of a plurality of access points (APs) and at least a second wireless AP of the plurality of APs, comprising:
the first wireless AP operable to transmit a first resource claim, the first resource claim comprising a first set of radio resources claimed for assignment by the first AP; the second wireless AP operable to transmit a second resource claim, the second resource claim comprising a second set of radio resources claimed for assignment by the second AP; and a mobile station operable to communicate interference mitigation data to the first wireless AP, the interference mitigation data associated with the first and second resource claims such that interference is mitigated, wherein the first resource claim, or the second resource claim, or both individually, each comprises one or more Orthogonal Frequency-Division Multiplexing (OFDM) symbols, wherein power is applied to at least one reference tone in each radio resource block that is being claimed, the at least one reference tone comprising one sub-carrier of one OFDM symbol and the power is applied to the reference tone at the transmit power level for the corresponding transmit power zone, and wherein the at least one reference tone is transmitted using the same parameters that are used for data transmission during a corresponding transmission opportunity.
