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
In this way, it cannot be guaranteed that users at the cell edge in adjacent cells use resources of different frequencies
Therefore, in high-frequency cells using beamforming technology, ICIC technology has been unable to effectively coordinate inter-cell interference, and there is no effective method for coordinating high-frequency inter-cell interference in the current technology

Abstract

The embodiment of the present invention discloses an inter-device cooperation method for coordinating interference between high-frequency cells. The method in the embodiment of the present invention includes: the first device sends the first beam to the target terminal; the second device sends the second beam to the target terminal; the target terminal measures the received first beam and the second beam; if the first measurement and the second measurement quantity meet the preset condition, the target terminal sends a notification message to the first device, instructing the first device to cooperate with the second device in transmission, so that the second device adjusts the second beam to reduce the impact of the second beam on the first beam. interference. Embodiments of the present invention also provide related beam training methods, related devices, equipment, terminals and systems.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for inter-device collaboration. 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 principle of adaptive antenna, which uses antenna array to carry ...
