BASIC STATION Russian patent published in 2018 - IPC H04W16/14 

FIELD: communication.

SUBSTANCE: invention relates to communication technologies and is designed to eliminate interference from an intermodulation signal, generated by a downlink created to an uplink signal, as for the same frequency band, and other frequency bands. In one variant, a base station is described, including an antenna unit and a radio frequency unit, port corresponding to the receive channel, which relates to the radio frequency unit and is in a working state, and the port, corresponding to the transmission channel, which relates to the radio frequency unit and is in the operating state, is separately connected to the ports, corresponding to different dipoles with double polarization or to different dipoles with a single polarization, available in the antenna unit, these different dipoles with double polarization or different dipoles with a single polarization, available in the antenna unit, are mutually isolated.

EFFECT: elimination of noise.
