Apparatus for transmitting WPAN MAC frames and method thereof
First Claim
1. An apparatus for transmitting WPAN (Wireless Personal Area Network) MAC (Medium Access Control) frames, comprising:
- a transport frame management unit for creating MAC transport frames through transport frames if the transport frames are generated from an upper protocol and application layer unit, classifying the created MAC transport frames by kinds, and managing the classified MAC transport frames by queues;
a first-stage transport frame storage unit for storing the transport frames under the management of the transport frame management unit;
a first-stage transport frame control information storage unit for storing storage information about the transport frames under the management of the transport frame management unit;
a transport memory control unit for transmitting the transport frames stored in the first-stage transport frame storage unit at a high speed;
a second-stage transport frame storage unit for storing the transport frames read and transferred from the first-stage transport frame storage unit by the transport memory control unit;
a second-stage transport frame control information storage unit for storing storage information about the transport frames read and transferred from the first-stage transport frame control information storage unit by the transport memory control unit; and
a transport frame transmission unit for grasping a position of the corresponding frame through the storage information stored in the second-stage transport frame control information storage unit if a transmission time of the transport frames is determined, reading and transmitting the transport frames stored in the second-stage transport frame storage unit to a physical layer unit.

Abstract
Disclosed is an apparatus for transmitting WPAN (Wireless Personal Area Network) MAC (Medium Access Control) frames and method thereof. The apparatus includes a transport frame management unit for creating MAC transport frames if data is generated from an upper protocol and application layer unit, classifying the created MAC transport frames by kinds, and managing the classified MAC transport frames by queues, a transport memory control unit for transmitting the transport frames at a high speed, and a transport frame transmission unit for responsible for the transmission of the transport frames by judging the transmission time of the frames. The apparatus can efficiently support the IEEE 802.15.3 standard by designing a queue structure capable of managing the WPAN MAC frames according to user'"'"'s priority information and traffic characteristics in a WPAN device for supporting video/audio streams.
