1. A method for generating a physical layer (PHY) data unit for transmission in a wireless local area network (WLAN), the method comprising:

  • determining, at a communication device, that the PHY data unit is to be transmitted according to a hybrid automatic repeat request (HARQ) process;

    generating, at a communication device, a PHY data portion of the PHY data unit, wherein generating the PHY data portion comprises;

    generating one or more PHY protocol service data units (PSDUs), andin response to determining that the PHY data unit is to be transmitted according to the HARQ process, individually encoding PSDUs of the one or more PSDUs;

    generating, at a communication device, a PHY preamble, wherein generating the PHY preamble comprises;

    generating a first signal field in the PHY preamble, andin response to determining that the PHY data unit is to be transmitted according to the HARQ process;

    including in the first signal field an indicator to indicate that the PHY preamble includes a second signal field with HARQ information regarding the PHY data unit, andgenerating the second signal field to include one or more indications of one or more durations of the one or more respective PSDUs within the PHY data portion, wherein the second signal field is separate from the first signal field.
