Abstract
A pilot frequency transmitting method comprises: in a downlink frame, a base station transmitting a MIMO midamble on the jth symbol of the ith downlink subframe; wherein i is a natural number which is less than or equal to the maximum number of downlink subframes included in the downlink frame, and j is a natural number which is less than or equal to the maximum number of symbols included in the downlink subframe. Accordingly, the present invention also provides a pilot frequency transmitting method and a base station for transmitting a MIMO midamble. The present invention can obtain a better effect for channel measurement by selecting an appropriate transmitting opportunity and/or manner of the MIMO midamble.
