Frame processing apparatus and method in wireless LAN

An access point of a wireless local area network comprising:

• an interface for transmitting/receiving frames to/from at least one station via a wireless medium;
• a frame processor for determining split size information corresponding to a quality status according to a signal level value acquired from a frame received via the interface, an error status of the received frame or a receipt status of an acknowledgment frame received in response to frame transmission;
• and
• a memory for storing the split size information according to the wireless medium determined by the frame processor.

A station of a wireless local area network comprising:

• an interface for transmitting/receiving frames to/from an access point via a wireless medium;
• a frame processor for determining split size information of a frame to be transmitted to the access point according to a signal level value acquired from a frame received via the interface, an error status of the received frame or a receipt status of an acknowledgment frame received in response to frame transmission;
• and
• a memory for storing the split size information of the access point determined by the frame processor.

A frame processing method in a wireless local area network, comprising steps of:

• confirming a quality status according to a signal level value of a frame received via a wireless medium, an error status of a frame or a receipt status of an acknowledgment frame in response to frame transmission;
• determining split size information of a transmitting frame according to the quality status;
• and
• upon generation of a frame to be transmitted, splitting and transmitting the frame according to size information of the frame and the split size information.

A frame processing method in an access point comprising steps of:

• confirming quality status according to signal level value of a frame received via a wireless medium from at least one station, error status of a frame or receipt status of an acknowledgment frame in response to frame transmission;
• determining split size information of a frame to be transmitted to the station according to the quality status;
• and
• upon generation of the transmitting frame, splitting and transmitting the transmitting frame according to size information of the station and the split size information.

A frame processing method in a station comprising steps of:
