Abstract

The present invention discloses an inter-base station beam configuration and management method, a base station, user equipment, and a system. The method includes: receiving, by user equipment, a beam signal sent by a base station; determining, by the user equipment, a receive beam based on the sent beam signal; receiving, by the base station, a beam signal sent by a terminal device; determining, by the base station, a receive beam based on the sent beam signal; performing dynamic selection and fast beam switching between base stations in combination with a coordinated multi-point technology; and performing fast beam alignment between the base station end with the user equipment end. This application can effectively implement fast beam switching and alignment between base stations and support dynamic base station selection, thereby improving link reliability.

Claims

1. An inter-base station beam configuration and management method based on a coordinated multi-point technology, comprising:

sending, by a base station, a beam signal to a terminal device; and

receiving, by the base station, a beam signal sent by the terminal device.
