Abstract

The invention discloses a device for suppressing wireless signal interference and a communication base station. The method comprises the steps that the device is installed on an antenna of a communication base station and comprises a signal shielding module and a connecting part, and the signal shielding module comprises a cavity structure with a notch and can achieve at least one of the following functions that the strength of a wireless signal transmitted by the communication base station through the antenna is weakened; weakening the intensity of the wireless signal received by the communication base station and refracted by the atmospheric waveguide layer for multiple times; and the connecting part comprises a cuboid structure with a gap and is used for connecting the cavity structure to an antenna of the communication base station. The technical problems that the wireless access performance of a 5G base station is reduced, the uplink and downlink rates of the base station are reduced and the switching performance is reduced due to the fact that an atmospheric waveguide signal interferes with a TDD network uplink signal are solved.

Description

technical field [0001] The present application relates to the field of wireless communication and terminals, and in particular, to a device and a communication base station for suppressing interference of wireless signals. Background technique [0002] For digital mobile communication, bidirectional communication can be separated by frequency or time, the former is called Frequency Division Duplex (FDD), and the latter is called Time Division Duplex (TDD). For FDD, different frequency bands are used for uplink and downlink. Generally, the bandwidth of uplink and downlink is the same. For TDD, the same frequency band is used for uplink and downlink. The time is divided into several time periods at fixed intervals, which are called guard periods (Guard Period, GP). At present, there are mainly two types of wireless networks: TDD and FDD. Compared with FDD, TDD technology has the following advantages: [0003] (1) Easy to use asymmetric frequency bands, no need for paired fre...
