Abstract: This application provides a communication method, a communications apparatus, and a system. The communication method includes: sending first indication information used to indicate that a system bandwidth of a first-type terminal device is a first system bandwidth, where the first system bandwidth is less than or equal to a cell-specific reference signal (CRS) mitigation bandwidth; and sending second indication information to a second-type terminal device, where the second indication information is used to indicate that a system bandwidth of the second-type terminal device is a second system bandwidth, and the second-type terminal device can support a network-based CRS mitigation technology. According to this application, communication performance of a conventional terminal device and a terminal device that can support a CRS mitigation technology in a network device configured with a network-based CRS mitigation technology can be ensured.

Abstract: The present disclosure discloses a method for transmitting an uplink measurement reference signal. The method is applied to a network-side device and includes the following operations: first, receiving, by the network-side device, an uplink measurement reference signal sent by user equipment, where the uplink measurement reference signal carries downlink interference information of a downlink channel of the network-side device; and then, performing downlink interference estimation on the uplink measurement reference signal, to obtain the downlink interference information. Compared with the prior art in which a base station cannot obtain downlink interference information of a downlink channel used by user equipment, in the present disclosure, the network-side device can effectively schedule the user equipment based on the downlink interference information, thereby improving scheduling efficiency, and improving data transmission efficiency of the downlink channel.
