1. A method, comprising:
receiving, by a terminal device from a base station through a downlink channel, a channel state information-reference signal (CSI-RS) configuration information code, the CSI-RS configuration information code comprising a first code and a third code;
determining, by the terminal device, a CSI-RS pattern based on the first code and a first relationship, the first relationship comprising a relationship among the first code, the quantity of antenna ports of the base station to transmit the CSI-RS and the CSI-RS pattern; and
determining, by the terminal device, a data muting resource element (RE) according to the third code.
