Step 201: base station receives the SINR measurement result that user terminal reports when report condition triggers;

Step 202: base station carries out subsequent analysis etc. based on SINR measurement result and processes.

It should be appreciated that user terminal also can report RSRP and/or RSRQ to base station in the present embodiment simultaneously.

In above-mentioned steps 102, the SINR measurement result of the Serving cell pilot signal obtained directly can be sent to base station by user terminal. Report condition now can by user or operator's sets itself, for instance when being set as the user terminal free time, user terminal charging time or periodically report etc. And user terminal reports the flow that the SINR measurement result of Serving cell pilot signal consumes can not charging in the present embodiment.

In above-mentioned steps 102, user terminal can report base station by the SINR measurement result of Serving cell pilot signal being carried in measurement report.
