    • A method and apparatus of a base station (BS) perform uplink (UL) random access in a wireless communication system. Random access channel information is determined on each of a plurality of frames constituting a superframe, and a control message comprising the random access channel information is broadcasted. A method and apparatus of a mobile station (MS) perform UL random access in a wireless communication system. A control message comprising random access channel information is received. A frame for minimizing a collision during a contention-based random access is selected based on the random access channel information. For data to be transmitted using the selected frame, it is determined whether the information to be transmitted is an access class with equal or higher priority to a received access class comprised in the random access channel information. A contention-based random access bandwidth request is transmitted to the BS for the data to be transmitted.
    • 基站(BS)的方法和装置在无线通信系统中执行上行链路(UL)随机接入。 在构成超帧的多个帧中的每一个上确定随机接入信道信息,并且广播包括随机接入信道信息的控制消息。 移动台(MS)的方法和装置在无线通信系统中执行UL随机接入。 接收包括随机接入信道信息的控制消息。 基于随机接入信道信息来选择用于在基于竞争的随机接入期间最小化冲突的帧。 对于要使用所选帧发送的数据,确定要被发送的信息是否是具有等于或更高优先级的接入类别,其对于包括在随机接入信道信息中的接收到的接入类别。 基于竞争的随机接入带宽请求被发送到BS以用于要发送的数据。
