Method and device for notifying reference signal configuration information

摘要

A method and a device for notifying reference signal configuration information are disclosed. Channel state information-reference signal (CSI-RS) configuration information is coded, to obtain a CSI-RS configuration information code. A mapping relation between the CSI-RS configuration information code and the CSI-RS configuration information is stored. A CSI-RS configuration information code corresponding to CSI-RS configuration information to be notified is searched in the stored mapping relation between the CSI-RS configuration information code and the CSI-RS configuration information. The searched CSI-RS configuration information code is sent to a user equipment (UE), so that the UE determines CSI-RS configuration information according to the received CSI-RS configuration information code and the mapping relation between the CSI-RS configuration information code and the CSI-RS configuration information.

主权项

1. A method for transmitting reference signal configuration information, comprising:
determining, by a base station, a channel state information-reference signal (CSI-RS) pattern, and number of antenna ports of the base station corresponding to the CSI-RS pattern; determining, by the base station, a CSI-RS period and a sub-frame offset; determining, by the base station, a data muting position; determining, by the base station, a first code according to a relationship between the first code, the number of antenna ports of the base station and the CSI-RS pattern, a second code according to a relationship between the second code, the CSI-RS period and the sub-frame offset, and a third code indicating the data muting position; transmitting, by the base station, channel state information-reference signal (CSI-RS) configuration codes to a terminal device, wherein the CSI-RS configuration codes comprise the first code, the second code and the third code.
