1. A method, comprising,
receiving a physical layer protocol data unit (PPDU) including data blocks,
wherein the PPDU includes a legacy signal (L-SIG) field, a repeated L-SIG field (RL-SIG) which is a repeat of the L-SIG field and is contiguous to the L-SIG field, and a universal signal (U-SIG) field which is contiguous to the RL-SIG field,
wherein each symbol of the U-SIG field carries 26-bit information, and the U-SIG field comprises version independent fields including bits related to transmission opportunity (TXOP) and bits related to a Basic Service Set (BSS) Color,
wherein the version independent fields are followed by version dependent fields in the U-SIG field,
wherein a number of the data blocks are related to one of at least one feedback bit; and
transmitting the at least one feedback bit based on the number of the data blocks,
wherein the number of the data blocks is determined by a following equation,

OG Complex Work Unit Math
where PSDU length denotes a length of a Physical Service Data Unit (PSDU) of the PPDU, and R denotes a code rate of the PPDU.
