1. A method for wireless communication, the method comprising:

  • receiving, at a communication device, a physical layer (PHY) protocol data unit (PPDU), wherein the PPDU includes i) a PHY preamble and ii) PHY data portion that includes one or more PHY midambles, and wherein the PHY preamble includes i) an indication of a length of the PPDU, and ii) an indication of a periodicity of PHY midambles in the PHY data portion;

    calculating, at the communication device, a number of PHY midambles in the PPDU using i) the indication of the length of the PPDU, ii) the indication of the periodicity of PHY midambles, and iii) a parameter corresponding to a minimum number of orthogonal frequency division multiplexing (OFDM) symbols permitted after a last-occurring PHY midamble in the PPDU;

    calculating, at the communication device, a reception time for the PPDU using the calculated number of PHY midambles; and

    processing, at the communication device, the PPDU using the calculated reception time.
