    Abstract: An apparatus for allocating channels in a communication system includes: a receiving unit configured to receive terminal information from a plurality of terminals, the terminal information containing information on data transmission/reception schemes of the terminals; a checking unit configured to check the data transmission/reception schemes of the terminals and check interference at channels allocated to the terminals; and an allocating unit configured to allocate primary and secondary channels to the terminals based on the data transmission/reception schemes of the terminals, change the primary and secondary channels based on the interference, and allocate the changed channels to the terminals; and a transmitting unit configured to transmit channel allocation information on the primary and secondary channels allocated to the terminals to the terminals.

    Abstract translation: 一种用于在通信系统中分配信道的装置包括：接收单元，被配置为从多个终端接收终端信息，所述终端信息包含关于所述终端的数据发送/接收方案的信息; 检查单元，被配置为检查终端的数据发送/接收方案，并检查分配给终端的信道的干扰; 以及分配单元，被配置为基于所述终端的数据发送/接收方案向所述终端分配主要和次要信道，基于所述干扰改变所述主要和次要信道，并且将改变的信道分配给所述终端; 以及发送单元，被配置为向所述终端发送分配给所述终端的所述主信道和所述次信道的信道分配信息。

    Abstract: A wireless device of a communication system randomly selects a backoff counter at a contention window interval corresponding to a contention window size that is determined according to a backoff stage, attempts packet transmission, when the backoff counter becomes 0 while reducing the backoff counter, when a radio channel is in an idle status, and increases the contention window size while increasing the backoff stage by 1 according to a first predetermined condition. In this case, as the backoff stage increases, a contention window size has a concave down increasing form.

    Abstract translation: 通信系统的无线装置在对应于根据退避阶段确定的竞争窗口大小的竞争窗口间隔随机地选择退避计数器，当拒绝计数器变为0同时减少退避计数器时，尝试分组传输，当a 无线电信道处于空闲状态，并且根据第一预定条件增加竞争窗口大小，同时将退避阶段增加1。 在这种情况下，当退避阶段增加时，竞争窗口大小具有凹下向上的形式。
