Problems solved by technology

However, in the beamforming technology, in order to align the target terminal, the transmitting beam formed by the antenna array will dynamically track the position of the target terminal, and the transmitting beam is likely to track the target terminal from the center of the cell to the cell boundary, or even track the target terminal to neighboring districts

Abstract

An embodiment of the invention discloses an inter-equipment coordination method used for coordinating interference among high frequency cells. The method provided by the embodiment of the invention includes that a first equipment sends a first wave beam to a target terminal; a second equipment sends a second wave beam to the target terminal; the target terminal measures the received first wave beam and the second wave beam; if the first measurement value and the second measurement value meet preset conditions, the target terminal sends notification to the first equipment and indicates the first equipment and the second equipment for transmission coordination, so that the second equipment is enabled to adjust the second wave beam so as to reduce interference on the first wave beam by the second wave beam. The embodiment of the invention also provides a related wave beam training method and related device, equipment, terminal and system.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for inter-device cooperation, an interference determination method, a beam training method and a device. Background technique [0002] The traditional working frequency bands of traditional mobile communications are mainly concentrated in the frequency bands below 3GHz, and the spectrum resources are very crowded, while the available spectrum resources in the high-frequency bands (such as millimeter wave and centimeter wave frequency bands) are abundant, which can effectively alleviate the shortage of spectrum resources and realize extremely high-speed short-term distance communication. Therefore, it can be said that the mining application of high-frequency band resources is the development trend of future mobile communications. High-frequency cells widely adopt beam forming (BF, Beam Forming) technology to increase coverage. Beamforming technology is based on the pri...
