1. A method for transmitting data blocks in a wireless communication system, the method performed by a transmitter and comprising:

  • generating a data block in a Medium Access Control (MAC) layer;

    generating a first padded data block by appending zero or more MAC padding bits to the data block;

    delivering the first padded data block from the MAC layer to a physical (PHY) layer;

    generating a second padded data block by appending zero or more PHY padding bits to the first padded data block in the PHY layer; and

    transmitting a PHY protocol data unit (PPDU) to a receiver over an operating channel, the PPDU including a first signal field, a second signal field and the second padded data block,wherein the first signal field includes control information used to interpret the PPDU, the control information including a bandwidth field indicating a bandwidth of the operating channel over which the PPDU is transmittedwherein the second signal field includes information indicating a modulation and coding scheme for the data block,wherein a total number of bits for the second signal field varies according to the bandwidth of the operating channel, andwherein the second signal field is present in the PPDU when the PPDU is a multi-user (MU)-PPDU.
