Problems solved by technology

[0004] However, avoiding interference by time-dividing the subframes of the backhaul link and the subframes of the access link will reduce the spectral efficiency by one time. Using twice as much spectrum resources will also result in lower spectrum utilization efficiency

Abstract

The embodiment of the present invention discloses a method for suppressing signal interference and a network device, which relate to the field of communication systems, and can realize simultaneous and same-frequency communication of a backhaul link and an access link, thereby improving spectrum utilization efficiency. The method includes: first, the network device sends a transmission signal, and then receives a first self-interference signal and a service signal, the first self-interference signal is a self-interference signal between a first antenna and a second antenna in the network device, Finally, cancellation is performed on the first self-interference signal, so as to reduce the interference of the transmitted signal on the service signal.

Description

technical field [0001] The invention relates to the field of communication systems, in particular to a signal interference suppression method and network equipment. Background technique [0002] With the continuous development of the communication system, the relay technology is introduced into the communication system. As a new node introduced in the network, the relay needs to add some new connection links. In the base station cell where there are relays, the connection links can be divided into access links and backhaul links according to different link service objects. The link serving between the relay and the base station is a backhaul link, and the link serving between the relay and the user equipment is an access link. [0003] Relay (relay) technology is a relay method. The working mechanism is to transmit the signal of the user equipment to the remote base station wirelessly, and access it to the core network through the base station. In the current Relay standar...
