Title:
DATA TRANSMISSION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/179273
Kind Code:
A1
Abstract:
Embodiments of the present application relate to the technical field of communications, and provide a data transmission method and apparatus, for use in solving the problem of low signal-to-noise ratio of a received signal due to that residual self-interference signals in full duplex communication contaminate the received signal. The method is applied to a device supporting full duplex communication. The method comprises: sending a first data frame and receiving a second data frame on a same time-frequency resource, wherein both the first data frame and the second data frame comprise multiple OFDM symbols, and a pilot sequence used by the OFDM symbols of the first data frame and a pilot sequence used by the OFDM symbols of the second data frame are orthogonal to each other.
