Abstract
A wireless communication method for transmitting wireless signals from a transmitter includes dividing bits of the transport block into a number of code blocks, wherein each code block corresponds to a bit-level of a multi-level modulation scheme used for transmission, and wherein a size of each code block is inversely proportional to a corresponding coding rate used for coding the code block.
Claims20
A wireless communication method of wireless communication in which data is transmitted in units of transport blocks, comprising:
- dividing bits of a transport block into a plurality of code blocks, wherein each code block of the plurality of code blocks corresponds to a bit-level of a multi-level modulation scheme used for transmission, and wherein a size of each code block is inversely proportional to a corresponding coding rate used for coding the code block;
- processing the plurality of code blocks to generate an output signal;
- and
- transmitting the output signal.

A wireless data transmission apparatus, comprising
- a first circuit at which data is received for transmission over a network;
- a second circuit which organizes the data into a plurality of code blocks;
- a processor that processes the plurality of code blocks to generate a quadrature amplitude modulation (QAM)-modulated output signal;
- and
- a transmitter circuit that transmits the QAM-modulated output signal,
- wherein sizes of the plurality of code blocks are selected such that at least one code block per bit level of a multi-level encoding is used, wherein each of the plurality of code blocks has a size less than or equal to a maximum size, wherein a size of each code block is inversely proportional to a corresponding coding rate used for coding the code block, and wherein coded bit levels occupy a same number of QAM symbols.
