METHOD AND APPARATUS FOR SENDING SIGNALS

WIPO Patent Application WO/2017/148190

A1

Disclosed are a method and apparatus for sending signals, for use in improving the channel estimation accuracy of a receiving end, so as to improve the data decoding accuracy of the receiving end. The method is applied to a system comprising a preamble and a payload (PL) field in a physical layer frame structure. The method comprises: inserting one or more pilot time-domain symbols between OFDM time-domain symbols in a PL field to obtain a physical layer frame; and sending the physical layer frame to a receiving end, wherein a preamble and the pilot time-domain symbol are used together for channel estimation of the receiving end.
