Title:
METHOD FOR TRANSMITTING CHANNEL ESTIMATION REFERENCE INFORMATION, CHANNEL ESTIMATION METHOD, TRANSMITTER AND RECEIVER
Document Type and Number:
WIPO Patent Application WO/2016/101271
Kind Code:
A1
Abstract:
Provided in an embodiment of the present invention is a method for transmitting channel estimation reference information, comprising: with respect to N continuous sub-carriers such as —N/2，—N/2+1,..., N/2-2, N/2-1, loading, on a sub-carrier 4m+2, a reference signal X(4m+2) corresponding thereto, and loading zero on other sub-carriers, N being a multiple of 8, and —N/8+1≤m≤N/8-2; executing a frequency domain-time domain conversion with respect to the N continuous sub-carriers to obtain a conversion result {x(n)}, 0≤n≤N/4—1; generating a protection interval GI according to {-x(n)}; and transmitting the channel estimation reference information {GI, x(n)}. Also provided in the embodiment of the present invention are a channel estimation method, transmitter and receiver. With respect to N continuous sub-carriers, the technical solution provided in the embodiment of the present invention can conduct channel estimation on each sub-carrier capable of wireless transmission according to a reference signal borne on the sub-carrier 4m+2.
