Step 101, the notification message for receiving first base station transmission；The notification message includes sign, and whether the CRS that the sign is used in the RRC signaling for the first base station transmission that instruction is received is effective.
Alternatively, the notification message can be RRC signaling or DCI signalings.
In the present embodiment, for example, when notification message is RRC signaling, it can represent whether CRS is effective by increasing a field in RRC signalings.Specifically, increasing a field in RRC signaling to represent whether effective manner is CRS：Increase " value_qcl-CRS-Info-rll " field in " CSI-RS-ConfigNZP " field information in RRC signalings, for example：When " this field of value_qcl-CRS-Info-rir is 1, then shows that CRS is effective；When " value_qcl-CRS-Info-rir, this field is 0, then shows that CRS is invalid.
Specifically, what is provided in the embodiment of the present invention increases a field for table in RRC signaling;The implementation example of the effective methods of CRS is as follows：
CSI-RS-ConfigNZP-rl 1：:= SEQUENCE {
