DATA MULTIPLEXING AND DATA PARSING METHOD, DEVICE, AND SYSTEM

摘要

Embodiments of this application provide a data multiplexing method, a network-side device, and a terminal. The method includes: transmitting, by a network-side device, a channel state information-reference signal CSI-RS and a data signal to a terminal, where the CSI-RS is used for channel state measurement or beam quality measurement; and sending, by the network-side device, CSI-RS multiplexing indication information to the terminal, where the CSI-RS multiplexing indication information is used to indicate whether frequency division multiplexing is performed on the data signal transmitted to the terminal and the CSI-RS. In the embodiments of this application, the CSI-RS multiplexing indication information is used to indicate whether multiplexing is performed on the CSI-RS and a data channel, so that multiplexing on the CSI-RS and the data channel becomes possible. In addition, the terminal can correctly parse user data based on the CSI-RS multiplexing indication information, so that resource utilization efficiency of the terminal is greatly improved.
