Abstract:
1. A method for configuring and sending a downlink CSI reference signal, comprising the following steps: an eNB configuring the downlink CSI reference signal and sending configuration information of the downlink CSI reference signal to a UE, wherein the configuration information comprises a starting subframe number and/or a cycle of the downlink CSI reference signal, and wherein the configuration information is sent with signalling which identifies the starting subframe number and the cycle of the downlink CSI reference signal, in a combined or separate manner; and the eNB sending the downlink CSI reference signal to the UE according to the configuration information of the downlink CSI reference signal, wherein the configurations of the cycle and the starting subframe number of the downlink CSI reference signal are prevented from interfering with PBCH/P-SCH/S-SCH channels.
