    Abstract: Disclosed is a bitmap structure which enables the size of a bitmap field containing reception result information to be significantly reduced while fully performing its acknowledgment function. To this end, a message region for recording indicators, which enables reception success or failure for the maximum allowable SN level packets treatable by block ACK to be confirmed, is assigned. A message region for recording only the reception results for unsuccessfully received packets is also assigned. A receiving party confirms the unsuccessfully received packets through the indicators, and retransmits the unsuccessfully received packets. Also, a transmitting party provides the number of SN level packets and the maximum number of fragmentation packets to the receiving party. The receiving party determines an optimized bitmap configuration scheme, and transmits the reception results for the respective fragmentation packets to the transmitting party based on the determined bitmap configuration scheme.

    Abstract: In the data transmission method, a MAC layer receives data from an upper layer, classifies the data according to destination addresses and traffic identifiers, aggregates the data by destination address and traffic identifier as a first transmission unit, aggregates the first transmission units having the identical destination address as a second transmission unit, and transmits the second transmission units having different destination addresses in a single frame. The data transmission method allows packets transferred from the upper layer to be hierarchically aggregated by DAs and TIDs and then packaged into a data unit for each destination such that it is possible to transmit the data at an optimal data rate for each destination terminal.

    Abstract: A method of forming patterns of a semiconductor device may include forming a photoresist layer that includes a photo acid generator (PAG) and a photo base generator (PBG), generating an acid from the PAG in a first exposed portion of the photoresist layer by first-exposing the photoresist layer, and generating a base from the PBG in a second exposed portion of the photoresist layer by second-exposing a part of the first exposed portion and neutralizing the acid. The method may also include baking the photoresist layer after the first and second-exposing and deblocking the photoresist layer of the first exposed portion in which the acid is generated to form a deblocked photoresist layer, and forming a photoresist pattern by removing the deblocked photoresist layer by using a developer.
