Determining HARQ parameters includes determining initial HARQ parameters, including an initial number of orthogonal frequency division multiplexing (OFDM) symbols that will be occupied by the HARQ data unit and an initial pre-coding padding factor corresponding to a boundary within a last OFDM symbol. Based at least in part on the initial pre-coding padding factor, it is determined whether the HARQ data unit will be misaligned with both a beginning of a first OFDM symbol occupied by the HARQ data unit and an end of a last OFDM symbol occupied by the HARQ data unit. When it is determined that the HARQ data unit will be misaligned, the initial pre-coding padding factor is adjusted to account for a reduced data tone OFDM symbol segment to be occupied by the HARQ data unit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Physical layer (PHY) data unit encoding for hybrid automatic repeat request (HARQ) transmission","description":"Hybrid automatic repeat request (HARQ) parameters for transmission of respective HARQ data units are determined.
