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 translation: 目的：提供CR（认知无线电）网络中的接收确认传输方法及其装置，通过发送包括接收确认响应信息的数据帧来提高数据传输速率。 构成：发送接收装置（730）向目标终端发送无线帧，并接收目标终端发送的数据帧。 处理器（710）在功能上与发送和接收装置相连。 处理器通过获取包含在数据帧的MAC（媒体访问控制）头部中的接收确认信息，基于接收确认信息来确定无线帧的传输状态。

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).

Abstract translation: 目的：提供多信道环境中的后备信道管理方法及其装置，通过更新信道信息来同时管理支持多个信道的无线网络中的一个或多个数据传输信道和一个或多个备用信道。 构成：如果CR（认知无线电）终端的操作模式被确定为备用信道使用模式，则CR终端确定信道（S510，S520）。 当所确定的信道是传输信道时，CR终端通过信标调度通过信标发送光（S530，S540，S545）。 CR终端通过分配超帧来发送和接收控制信息（S550，S555）。 CR终端发送和接收信道质量测量信息（S560，S565）。
