Title:
SIGNAL TRANSMISSION METHOD, DEVICE AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/037788
Kind Code:
A1
Abstract:
Disclosed in the present application is a signal transmission method, comprising: a terminal device obtains data to be transmitted, uplink control information, and a demodulation reference signal; mapping the data to be transmitted, the uplink control information, and the demodulation reference signal to generate multiplexing symbols, which comprises discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM) symbol or an orthogonal frequency division multiplexing (OFDM) symbol, wherein N first multiplexing symbols are located at one side or two sides of a second multiplexing symbol, a positional relationship between the N first multiplexing symbols and the second multiplexing symbol satisfies a mapping condition, N is an integer greater than or equal to 1, the first multiplexing symbol is a multiplexing symbol where the uplink control information is mapped, and the second multiplexing symbol is a multiplexing symbol where the demodulation reference signal is mapped; and transmitting the multiplexing symbols over a physical uplink shared channel. The technical solution of the present application can improve the demodulation performance of UCI.
