Code block segmentation by OFDM symbol

Abstract:

According to some embodiments, a method in a wireless transmitter of aligning code blocks with modulation symbols comprises: receiving a block of information bits for wireless transmission in a plurality of modulation symbols; partitioning the plurality of modulation symbols into groups of one or more modulation symbols, wherein the modulation symbols in a group are contiguous in time; and assigning each of the information bits to one of the groups. For each of the groups the method further comprises: segmenting the assigned information bits in the group into one or more code blocks; encoding each code block into coded bits; and assigning the coded bits of the one or more code blocks to the group of modulation symbols the information bits are assigned to. The method further comprises transmitting the groups of modulation symbols to a wireless receiver.
