Abstract
A method, an apparatus and a system for sending Sounding Reference Signal (SRS) and a method, an apparatus and a system for receiving SRS are disclosed in the present invention, which are used to reduce the requirement for Time Frequency Code (TFC) resource during the process of sending the SRS, and meanwhile to ensure the precision of channel information estimation. The method includes the steps of: determining a first frequency band required by sending the SRS, and determining a second frequency band whose width is smaller than the width of the first frequency band; according to the mode that the average interval for sending the SRS on the first frequency band is larger than the average interval for sending the SRS on the second frequency band, respectively sending the SRS on the first frequency band and the second frequency band.
