Abstract: A base station maps code blocks of a transport block of a transport block size (TBS) for a channel using tone-level interleaving or resource element (RE)-level interleaving. Then, the base station can transmit the code blocks of the transport block of the TBS for the channel. A UE may receive the channel from the base station and de-interleave the received tones of the channel in a frequency domain to obtain the code blocks of the transport block having the TBS for the channel.

Abstract: An apparatus (e.g., receive chain) for wireless communications may perform de-interleaving, de-rate matching, and hybrid automatic repeat request (HARQ) combining in a single step. The apparatus may include a data pool configured to store HARQ log likelihood ratio (LLR) data from previous transmissions. The apparatus may include a HARQ onload controller configured to load HARQ LLR data from the HARQ data pool into a HARQ buffer. The apparatus may include an LLR buffer configured to store received demodulated, interleaved, and rate matched LLR data. The apparatus may include a plurality of processing engines configured to, starting at different locations of the LLR buffer: receive new input data from the LLR buffer; combine the HARQ LLR data from the HARQ buffer with the new input data to generate de-interleaved, de-rate matched, and HARQ combined data; and write the de-interleaved, de-rate matched, and HARQ combined data into the HARQ buffer.
