METHOD AND APPARATUS FOR TRANSMITTING CHANNEL MEASUREMENT PILOT

摘要

A method for transmitting channel measurement pilot is provided in the present invention. The method includes that: M cells constitute a group of channel measurement pilot orthogonal cells, the location of time-frequency resources for transmitting the channel measurement pilot by any cell in the group is orthogonal with the location of time-frequency resources for transmitting the channel measurement pilot by other cells in the group; for any cell in the group, the channel measurement pilot is transmitted by avoiding the time-frequency resources occupied by a downlink specific pilot of the present cell. The corresponding apparatus is also provided in the present invention. The present invention not only ensures the orthogonality of the channel measurement pilot pattern in one group of cells, meets the measurement requirement of coordinated multiple point transmission, but also avoids the downlink specific pilot of antenna port 5.
