Title:
SIGNAL TRANSMISSION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/133407
Kind Code:
A1
Abstract:
The embodiment of the application provides a signal transmission method comprising: a communication apparatus acquires, from a bitstream to be transmitted, a bit set comprising two or more bits; the communication apparatus modulates the bit set on the basis of a codebook to obtain two or more modulated symbols; the communication apparatus maps each of the two or more modulated symbols to a corresponding timeslot in a frame; and the communication apparatus transmits the two or more mapped modulated symbols; wherein different modulated symbols obtained from a same bit set are mapped to different timeslots, and each timeslot comprises a plurality of continuous modulated symbol mapping locations for mapping modulated symbols obtained according to a plurality of bit sets in the bitstream to be transmitted. The embodiment of the invention can reduce transmission power consumption at a transmitter, and is particularly suitable for massive data transmission in a 5G communication system.
