Aggregated Interference Steering Interference Management Method, Hybrid Cellular Network, Wireless Local Area Network

Abstract

The invention belongs to the technical field of wireless communication, and discloses an aggregated interference guided interference management method, a hybrid cellular network and a wireless local area network. A target communication pair and an interference communication pair separately design a pre-coding vector and a filtering vector; according to the spatial characteristic relationship and the interaction among multiple interference signals received by a target communication receiver, multiple channels of interference signals are equivalent to a channel of effective interference signal by a target communication transmitter; the target communication transmitter designs the pre-coding vector of an interference guidance signal for the equivalent interference signal; the target communication transmitter constructs a guidance signal, and sends the guidance signal to the target communication receiver together with an expected signal; the interference guidance signal adjusts the equivalent interference signal in the direction orthogonal with the expected signal, so that aggregated interference guidance is realized; and the target communication receiver recovers expected data. According to the aggregated interference guided interference management method, the hybrid cellular network and the wireless local area network disclosed by the invention, the multiple interference signalsare equivalent to a channel of interference signal by utilization of the mutual relationship; therefore, the freedom degree cost of multiple channels of interference guidance can be reduced; and the spectra efficiency is increased.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to an aggregation interference-guided interference management method, a hybrid cellular network, and a wireless local area network.
