    • PROBLEM TO BE SOLVED: To provide a slot assignment method adopting a TDD system with high efficiency and high flexibility that is suitable for accommodation of vertically asymmetrical traffic, attains slot assignment in response to the quality of service and improves the throughput. SOLUTION: A plurality of borders for changeover of incoming slots and outgoing slots in one frame is provided to assign slots, and TDD borders are dynamically changed according to prescribed conditions. A base station assigns slots and informs a mobile station about the assigned slots by using a control mini-slot in a frame. This method is characterized in that a slot number less than a requested slot number in a congestion state is assigned and a slot number more than the requested slot is assigned in a congestion-free state depending on the traffic congestion state on the basis of the QoS such as a service ranking.
    • 要解决的问题:为了提供适用于适应垂直不对称业务的具有高效率和高灵活性的TDD系统的时隙分配方法,响应于服务质量获得时隙分配并提高吞吐量。 解决方案:提供用于切换一帧中的输入时隙和输出时隙的多个边界以分配时隙,并且TDD边界根据规定的条件动态地改变。 基站通过使用帧中的控制小时隙来分配时隙并通知移动台关于所分配的时隙。 该方法的特征在于,在拥塞状态下分配小于所请求的时隙号的时隙号,并且根据QoS的业务拥塞状态,在无拥塞状态下分配比所请求的时隙多的时隙号 如服务排名。
