    • A base station includes an apparatus and a method for exchanging frequency channel resources between base stations in a Cognitive Radio (CR) based communication system. A requesting Base Station (BS), which requests channel exchange a neighboring BS, receives a channel advertisement message from a neighboring BS and sends a channel exchange request message to the neighboring BS. The channel exchange request message includes at least one of a neighbor BS Identifier (ID), a requesting BS ID, channel information for the channel exchange at the requesting BS, and channel information exchangeable at the neighboring BS. The requesting BS receives a channel exchange response message from the neighboring BS in response to the channel exchange request message, determines whether to execute a channel exchange process to the neighboring BS based on information in the received channel exchange response message, and sends a channel exchange reply message indicative of the determination result.
    • 基站包括用于在基于认知无线电(CR)的通信系统中的基站之间交换频率信道资源的装置和方法。 向相邻BS请求信道交换的请求基站(BS)从相邻BS接收信道通告消息,并向相邻BS发送信道交换请求消息。 信道交换请求消息包括相邻BS标识符(ID),请求BS ID,用于在请求BS处的信道交换的信道信息和在相邻BS可交换的信道信息中的至少一个。 请求BS响应于信道交换请求消息从相邻BS接收信道交换响应消息,基于接收到的信道交换响应消息中的信息确定是否对相邻BS执行信道交换过程,并发送信道交换 表示确定结果的回复消息。
