Problems solved by technology

[0009] In practical applications, there are the following problems: the terminal has a large amount of calculation when modulating data to resource blocks, and it cannot guarantee the optimal average of the interference between different layers in the quasi-orthogonal reverse channel
In addition, the generated random sequence cannot guarantee that the number of times the terminal occupies the same physical channel resource block with the same other terminal is 1, so it cannot guarantee the optimal average of the interference between different layers in the quasi-orthogonal reverse channel

Embodiment Construction

[0075] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0076] The core of the present invention is that the terminal uses the Reed-Solomon code or the extended Reed-Solomon code as the mapping mode from the basic node of the logic channel tree of the quasi-orthogonal reverse link to the resource block of the physical channel. Each terminal only needs to generate a Reed-Solomon code sequence or an extended Reed-Solomon code sequence related to the terminal, and map the transmission data to corresponding physical channel resource blocks in each time slot according to each value in the sequence.

[0077] The core of the present invention has been briefly described above, and the embodiments of the present invention will be described in detail below based on this principle.

[0078] The first embodiment of the present inv...

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...
