Abstract: Methods, systems, and devices for transmitter-side processing of preamble and reference signals are described. An exemplary method for wireless communication includes transmitting, by a wireless device, a message comprising modified symbols that are generated by performing a modification on baseline symbols. Another exemplary method for wireless communication includes receiving, by a network node, a message comprising modified symbols that are generated by performing a modification on baseline symbols. In an example, the message may be a random access message that is part of a 2-step random access channel (RACH) process or a contention-based physical uplink shared channel (PUSCH) or physical uplink control channel (PUCCH) transmission.

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.
