Provided is a channel resource assignment method for fair channel resource reservation in a mesh WPAN, in which the amount of channel resources is fairly reserved when devices share the channel resources. The channel resource assignment method in a mesh Wireless Personal Area Network (WPAN) includes the steps of: (a) transmitting beacons of all devices and adding an amount of channel resource to be reserved to the beacons so as to assign the channel resource for fair channel resource reservation between corresponding devices and adjacent devices when a mesh network is configured; (b) accumulating the amount of the channel resources reserved by all the adjacent devices except the corresponding device; and (c) determining the amount of the channel resources to be reserved.

A transmission controller used in a media access controlling (MAC) processing apparatus and a transmission controlling technique. The transmission controller includes a transmission frame sorting unit for sorting out transmission frames transmitted from an LLC layer based on each transmission service and requesting control of the transmission frames and a transmission queue controlling unit for requesting to store the transmission frames, information on the transmission frames, and controlling the transmission of the transmission frames. The transmission controller includes a transmission queue storing unit for storing information on the sorting of the transmission frames based on each transmission service or each mobile terminal and a frame controlling unit for storing the transmission frames, generating and storing CF POLL frames, and transmitting the transmission frames and the CF POLL frames to a wireless physical layer. The transmission controller includes a shared transmission frame storing unit and a CF POLL frame storing unit.
