Abstract

The invention relates to the wireless communication field, which discloses a method and device of the mapping method of the signal channel resource block, enables the complexity of the terminal modulation data to the resource block to be reduced, and effectively averages the disturbance between the various layers of the quasi-orthogonal reverse signal channel. According to the Reed-Solomon code sequence or the expanded Reed-Solomon code sequence, the invention maps the logic signal channel node of the quasi-orthogonal reverse chain path to the physical signal channel resource block.

Description

technical field

[0001] The invention relates to the field of wireless communication, in particular to the channel resource block mapping technology of the quasi-orthogonal reverse link. Background technique

[0002] In recent years, a multi-carrier transmission technology represented by Orthogonal Frequency Division Multiplexing (Orthogonal Frequency Division Multiplexing, "OFDM") has attracted widespread attention. Multi-carrier transmission decomposes a data stream into several independent sub-streams, each of which will have a much lower bit rate. Using the low-rate multi-state symbols formed at such a low bit rate to modulate the corresponding subcarriers constitutes a transmission system in which multiple low-rate symbols are sent in parallel.

[0003] As a multiplexing technique, OFDM multiplexes multiple signals on different orthogonal subcarriers. The traditional frequency division multiplexing (Frequency Division Multiplexing, referred to as "FDM") technology divi...
