Patent ID: 10958497

Abstract:
The present invention relates to a method and apparatus for processing a modulation symbol. The processing method includes: a transmitter obtaining a transmission power ratio αj, wherein in the transmission power ratio αj∈{α0, α1, α2}, j is a natural number, and α0, α1 and α2 are all positive numbers; and the transmitter modulating a first group of bit sequences b0(i), b0(i+1) and a second group of bit sequences b1(i), b1(i+1), . . . , b1(i+n) according to the transmission power ratio αj so as to obtain a modulation symbol, wherein i is a natural number, and n∈{1, 3, 5}. The present invention solves the problem in the relevant art that an uncertain number of transmission power ratios affects the performance of a system and increases the design complexity of signaling, thereby reducing signaling overheads and improving system stability and demodulation performance.
