Problems solved by technology

At present, the base station can only perform signature sequence detection on the same-frequency carrier, but cannot perform signature sequence detection on adjacent-frequency carriers. Therefore, the existing same-frequency atmospheric waveguide interference detection scheme is not suitable for adjacent-frequency interference detection.

Abstract

The invention provides an atmospheric waveguide interference processing method and device, a base station, a communication system and a storage medium. The method comprises the following steps: obtaining first detection information corresponding to a first edge PRB located at the edge of a first carrier and second detection information corresponding to a center PRB located at the center of the first carrier, judging whether adjacent channel interference detection is needed or not; if so, carrying out energy detection on a second edge PRB which is located at the edge of a second carrier and isadjacent to the first edge PRB, determining whether the second edge PRB is interfered with by the adjacent-channel atmospheric waveguide, and if so, sending interference detection information and carrying out interference avoidance processing based on interference avoidance configuration information issued by the network management system. According to the method and device, the base station, thecommunication system and the storage medium, the problem that adjacent-channel atmospheric waveguide interference greatly influences uplink receiving of the base station side can be solved, time-frequency resource expenditure and scheme complexity are both considered, and the method and device can be effectively applied to an existing network of an operator.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a method and device for processing atmospheric waveguide interference, a base station, a communication system, and a storage medium. Background technique [0002] Under certain meteorological conditions, the atmospheric waveguide effect will be formed, and the downlink signal transmitted by the distant interference base station will still be strong when transmitted to the distant place through the atmosphere. When the distance between the disturbed base station and the disturbing base station exceeds a certain distance, for the TDD system, during the conversion process from downlink transmission to uplink reception, the signal at the end slot of the downlink subframe will be transmitted at the beginning slot of the uplink subframe after long-distance transmission. Arriving at the disturbed base station, it interferes with the uplink reception of the disturbed b...
