    Abstract: PURPOSE: A channel allocation method of a wireless multi-channel recognition network is provided to minimize the number of operation channels in a multi channel recognition wireless network. CONSTITUTION: A specific channel set S1 is composed(S310). The capacity Cm is calculated for a channel m of the S1(S320). A task Jm is allocated in the channel of the S1(S330). Works allocated to the channel according to corresponding work distribution(S340,S360). It is determined whether to minimize total used channels(S350).

    Abstract: PURPOSE: A reception confirmation transmission method in a CR(Cognitive Radio) network and apparatus thereof are provided to increase data transmission rates by transmitting a data frame including reception confirmation response information. CONSTITUTION: A transmission and reception apparatus(730) transmits a wireless frame to a target terminal and receives a data frame transmitted by the target terminal. A processor(710) is functionally connected with the transmission and reception apparatus. The processor determines the transmission state of the wireless frame based on reception confirmation information by acquiring the reception confirmation information included in an MAC(Media Access Control) header of the data frame.

    Abstract: PURPOSE: A back-up channel management method in multiple channel environment and apparatus thereof are provided to simultaneously manage one or more data transmission channels and one or more back-up channels in a wireless network which supports multiple channels by updating channel information. CONSTITUTION: In case an operation mode of a CR(Cognitive Radio) terminal is determined as a backup channel usage mode, the CR terminal determines channels(S510,S520). When the determined channel is a transmission channel, the CR terminal transmits light through a beacon through a beacon schedule(S530,S540,S545). The CR terminal transmits and receives control information by allocating super frames(S550,S555). The CR terminal transmits and receives channel quality measurement information(S560,S565).
