Patent ID: 8681755

Claim:
A method of generating a data frame used in a wireless network, the method comprising: generating a plurality of sub frames by using one or more Media Access Control (MAC) Service Data Units (MSDUs); generating sub headers including information about the plurality of sub frames; and generating a PHY Service Data Unit (PSDU) by using the plurality of sub frames, the sub headers, and a MAC header, wherein each sub frame of the plurality of frames includes a Frame Check Sequence (FCS) field for detecting an error of a corresponding sub frame, and wherein the sub headers are not included in the plurality of sub frames, wherein the generating of the plurality of sub frames comprises: using first type bits and second type bits extracted from the one or more MSDUs and generating the plurality of sub frames including a sub frame containing the first type bits, a sub frame containing the second type bits, and a sub frame containing both the first type bits and the second type bits, wherein the sub headers include fields indicating a type of bits included in a corresponding sub frame, and wherein the sub headers include a field indicating whether an independent ACK is requested with regard to the first and second type bits of a corresponding sub frame.
