Embodiments of the invention disclose a method and device for sending a pilot signal. The method includes: generating a sub-frame carrying user-specific pilot signals, wherein the sub-frame includes one or more resource blocks, the resource block includes a plurality of resource elements in a symbol-subcarrier plane, locations of the resource elements in the symbol-subcarrier plane are determined by an OFDM symbol and a subcarrier, a first part of the user-specific pilots signal are carried by the resource elements of the initial one or more OFDM symbols in the resource block, and a second part of the user-specific pilot signals are carried by the resource elements of the other OFDM symbols in the resource block; and sending the sub-frame carrying the user-specific pilot signals. Using the present invention user-specific pilot signals may be carried by the resource elements of initial OFDM symbols of the resource block of a sub-frame, thus improving the precision of channel estimation. |
