Apparatus, system and method of communicating a physical layer protocol data unit (PPDU)

A product comprising one or more tangible computer-readable non-transitory storage media comprising computer-executable instructions operable to, when executed by at least one processor, enable the at least one processor to cause an Enhanced Directional Multi-Gigabit (DMG) (EDMG) wireless communication station (STA) to:

• determine a count of data pad bits for a user based on a count of Low-Density Parity-Check (LDPC) codewords for the user, a length of a Physical Layer (PHY) Service Data Unit (PSDU) for the user, an LDPC codeword length, and an LDPC code rate for the user;
• determine a scrambled PSDU for the user by scrambling a concatenation of the PSDU for the user with a first plurality of zero bits, a count of zero bits in the first plurality of zero bits is equal to the count of data pad bits for the user;
• convert the scrambled PSDU for the user into a plurality of LDPC codewords according to the LDPC codeword length and the LDPC code rate for the user;
• generate a coded bitstream based on the plurality of LDPC codewords;
• determine a count of coded pad bits for the user based on a count of Orthogonal Frequency Division Multiplexing (OFDM) symbols for the user, the count of LDPC codewords for the user, and the LDPC codeword length;
• generate encoded padded bits by concatenating the coded bitstream with a second plurality of zero bits, a count of zero bits in the second plurality of zero bits is equal to the count of coded pad bits for the user;
• and
• transmit an EDMG OFDM PHY Protocol Data Unit (PPDU) based on the encoded padded bits.

An apparatus comprising:

• processing means for causing an Enhanced Directional Multi-Gigabit (DMG) (EDMG) wireless communication station (STA) to generate encoded padded bits by:
• determining a count of data pad bits for a user based on a count of Low-Density Parity-Check (LDPC) codewords for the user, a length of a Physical Layer (PHY) Service Data Unit (PSDU) for the user, an LDPC codeword length, and an LDPC code rate for the user;
• determining a scrambled PSDU for the user by scrambling a concatenation of the PSDU for the user with a first plurality of zero bits, a count of zero bits in the first plurality of zero bits is equal to the count of data pad bits for the user;
• converting the scrambled PSDU for the user into a plurality of LDPC codewords according to the LDPC codeword length and the LDPC code rate for the user;
• generating a coded bitstream based on the plurality of LDPC codewords;
• determining a count of coded pad bits for the user based on a count of Orthogonal Frequency Division Multiplexing (OFDM) symbols for the user, the count of LDPC codewords for the user, and the LDPC codeword length;
• and
• generating the encoded padded bits by concatenating the coded bitstream with a second plurality of zero bits, a count of zero bits in the second plurality of zero bits is equal to the count of coded pad bits for the user;
• and
• control means for causing the EDMG STA to transmit an EDMG OFDM PHY Protocol Data Unit (PPDU) based on the encoded padded bits.
