LDPC code block segmentation

Abstract:

According to some embodiments, a method in a wireless transmitter comprises: receiving a plurality of bits for a wireless transmission; determining a maximum code block size for the transmission based on code rate, maximum code word size Nmax, and design parameters of the channel code; segmenting the plurality of bits into one or more code block segments such that no one of the one or more code block segments is larger than the determined maximum code block size; and transmitting the one or more code block segments to a wireless receiver. In particular embodiments, the design parameters of the channel code limit the maximum code block size to Kmax for any code rate. The determined maximum code block size may be limited by code rate and Nmax such that the maximum code block size does not exceed code rate times Nmax.
