Communication method and device

Abstract

The embodiment of the present application discloses a communication method and device, the method includes: the first network device sends first information to the terminal, the first information includes the signal quality threshold of the serving cell of the terminal and the signal quality threshold of the neighboring cell of the serving cell , or, the difference threshold between the signal quality of the beam of the serving cell and the signal quality of the beam of the neighboring cell. The first network device receives the first report sent by the terminal, the first report includes the identification information of the first cell and the identification information of the first beam of the first cell, and / or the first report includes the identification information of the second cell and the second The identification information of the second beam of the cell, the signal quality of the first beam reaches the signal quality threshold of the serving cell, the signal quality of the second beam reaches the signal quality threshold of the neighboring cell, or the difference between the signal quality of the first beam and the second beam The absolute value of the value is not greater than the difference threshold, which is beneficial to interference coordination among high-frequency cells.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a communication method and device. Background technique [0002] At present, mobile communication technology is developing in the direction of high speed and large data traffic, and the demand for spectrum in communication transmission is also increasing. Because traditional low-frequency spectrum resources are very crowded, high-frequency bands (such as millimeter wave and centimeter wave frequency bands are very crowded) ) spectrum has a large amount of available bandwidth, making high-band spectrum an important resource to meet the large-capacity and large-bandwidth requirements in future communications. Since a high-frequency cell using a high-frequency spectrum generally has a small coverage area and beam signals are easily blocked, the high-frequency cell widely adopts a Beam Forming (BF) technology to increase coverage.

Problems solved by technology

[0003] In 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. The transmitting beam is likely to track the target terminal from the center of the cell to the edge of the cell, or even track the target terminal to the edge of the cell. Adjacent cells, which easily lead to interference between adjacent beams, how to achieve interference coordination between high-frequency cells has become an urgent problem to be solved
