Abstract

Provided are a signal interference processing method and apparatus and a relay device. The signal interference processing apparatus of the present invention comprises: a power allocation module, an interference reconstruction module and a power synthesis module, wherein the power allocation module is used for acquiring a first signal to be sent by a first antenna, separating a second signal with a first set power from the first signal, and inputting the second signal into the interference reconstruction module; the interference reconstruction module is used for generating an interference cancellation signal using the second signal, and inputting the interference cancellation signal into the power synthesis module; and the power synthesis module is used for performing interference cancellation on a third signal received by a second antenna using the interference cancellation signal. The interference of the signal emitted by the first antenna to the signal received by the second antenna is avoided, and at the same time, the utilization efficiency of frequency spectrums is reduced when using the manner of time division or frequency division is avoided.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular, to a signal interference processing method, device, and relay equipment. Background technique [0002] In the current base station system, the base station sends data to the core network through the network cable. However, in places where there are no wired resources or where it is inconvenient to lay lines, such as Gobi, high mountains and other terrains, or time-critical areas such as post-earthquake disaster areas, etc. Scenarios, laying optical fiber networks for base station systems is not realistic enough, so the wireless backhaul technology (WirelessBackhual) for base station systems effectively solves the problems in the above scenarios. [0003] In the prior art, in the wireless backhaul technology, user equipment (User Equipment, UE for short) sends data to a relay device (Relay), and then the relay sends data to a remote base station, and then the r...
