Abstract

The embodiments of the invention provide a signal interference processing method and apparatus, and a relay device. The signal interference processing apparatus comprises a power distribution module, an interference reconstruction module and a power synthesis module, wherein the power distribution module is used for obtaining a first signal to be sent by a first signal, separating a second signal of first set power from the first signal, and inputting the second signal to the interference reconstruction module; the interference reconstruction module is used for the second signal to generate an interference offset signal and inputting the interference offset signal to the power synthesis module; and the power synthesis module is used for performing interference offsetting on a third signal received by a second antenna by use of the interference offset signal, such that the interference to the signal received by the second antenna from the signal emitted by the first antenna is avoided, and at the same time, the frequency spectrum utilization efficiency is prevented from being decreased when a time division mode or a frequency division mode is employed.

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 fiber optic networks for base station systems is not realistic enough, so the wireless backhaul technology (Wireless Backhual) 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 re...
