US Patent 10305633 Per-symbol K-bit interleaver

The present disclosure provides techniques for performing bit-level interleaving for orthogonal frequency-divisional multiplexing (OFDM) symbols across a plurality of code blocks. In some aspects, a transmitting device may dynamically switch between bit-level interleaving and tone-level interleaving for each OFDM symbol based on factors such as number of bits that are carried in each tone, size of each code block, the processing time requirements of the transmitting device and/or the receiving device, or the transmitting device preference.
