Abstract

The invention discloses a millimeter wave communication multi-user parallel beam training method based on a codebook. According to the method, parallel beam training is carried out on a multi-user system by designing beam forming of a sending end. Compared with the existing multi-user serial hierarchical beam training, the method has the advantage that the performance of the existing multi-user serial hierarchical beam training method can be approximated on the premise of greatly reducing the training overhead.

Description

technical field

[0001] The invention belongs to the field of millimeter wave wireless communication, and relates to a codebook-based multi-user parallel beam training method for millimeter wave communication. Background technique

[0002] With the popularity of mobile terminal devices, people's demand for wireless communication is also increasing. In order to meet people's increasing demand for data traffic, millimeter wave communication (30GHz-300GHz) has attracted widespread attention because of its rich spectrum resources and extremely high transmission rate.

[0003] Due to the higher carrier frequency than the existing conventional frequency band communication, millimeter wave communication will have greater path loss when propagating in space. On the other hand, higher carrier frequency enables mmWave communication with smaller antenna size. This enables a larger-scale antenna array to be packaged in a limited area, and the gain of the antenna array is used to compen...
