Abstract
A method for performing code block segmentation for wireless transmission using concatenated forward error correction encoding includes receiving a transport block of data for transmission having a transport block size, along with one or more parameters that define a target code rate. A number N of inner code blocks needed to transmit the transport block is determined. A number M—outer code blocks may be calculated based on the number of inner code blocks and on encoding parameters for the outer code blocks. The transport block may then be segmented and encoded according to the calculated encoding parameters.
Claims16
A user equipment (UE) comprising:
- a receiver configured to:
- receive a transport block of data for transmission having a transport block size;
- and
- receive a set of parameters that define a target code rate;
- and
- one or more processors configured to:
- determine a number N of inner code blocks needed to transmit the transport block;
- calculate a modulation and coding scheme (MCS) including a number M of outer code blocks based on the number N of the inner code blocks and on the set of parameters that define the target code rate;
- divide the received transport block into M outer code blocks and encode each of the M outer code blocks to form M encoded outer code blocks;
- segment the M encoded outer code blocks into N inner code blocks and encode the N inner code blocks to form N encoded inner code blocks;
- and
- arrange the N encoded inner code blocks to form an encoded transport block.
A user equipment comprising:
- a receiver configured to:
- receive and demodulate an encoded transport block having N encoded inner code blocks formed by M encoded outer code blocks;
- receive a set of parameters that define a target code rate and a size of a transport block, and
- one or more processors configured to:
- determine the number N of inner code blocks needed to transmit the transport block;
- calculate a modulation and coding scheme including the number M of outer code blocks based on the number N of the inner code blocks and on the set of parameters that define the target code rate;
- decode the N encoded inner code blocks in the encoded transport block to form the M encoded outer code blocks;
- and
- decode the M encoded outer code blocks.
