Abstract

Modulating and mapping method and device for DTX bits. Said method includes receiving binary symbols in a downlink physical channel; replacing the symbol values of DTX bits in said binary symbols with symbol values of non-DTX bits, then obtaining the updated binary symbols; and modulating and mapping said updated binary symbols. Using DTX bits to duplicate non-DTX bits, and supplying the receiving end with DTX bits that serve as redundant information to non-DTX bits, improves the ability of the receiving end to demodulate DTX bits. When all of the binary symbols in one path are DTX bits, once the binary symbols in same one path are modulated and mapped the output has a real number value of 0.
