A communication method, a communication device, and a communication system

Abstract

A communication method, communication device, and communication system are disclosed. The method includes: a terminal receiving indication information from an access network device, the indication information indicating a first transmitting port, which is one of a first type of transmitting ports, wherein the RSRP value of the interference from the first type of transmitting port to K receiving ports of the terminal satisfies the first condition, and the K receiving ports are K receiving ports out of N receiving ports of the terminal; and receiving data using the first receiving port, wherein the RSRP value of the interference received by the first receiving port from the first transmitting port does not satisfy the first condition, and the first receiving port is included in the N receiving ports but not in the K receiving ports. In this method, the terminal in the local cell selects an appropriate receiving port to receive data based on the indication from the access network device, so as to minimize the signal interference from data transmission from neighboring cells to the terminal in the local cell, thereby improving the signal-to-noise ratio, transmission rate, and transmission stability when the terminal receives data.
