    • Devices and methods are provided for managing random access data channels in a wirelessly-enabled communications environment. An uplink (UL) random access (RA) channel is implemented to send data to an access point (AP) without requiring a UL allocation grant message to be sent on the downlink (DL) for UL timing adjustments. A mobile station (MS) sends a chosen sequence to the AP to indicate that a RA data transmission is being requested. The location and number of radio resources that are used for the UL RA data transmission are determined by the choice of a RA sequence initially sent by the MS. If UL timing has not been established, the AP is able to determine the timing of the UL RA data transmissions by deriving the offset of the initial RA request sequence transmission from the MS.
    • 提供了用于在无线启用的通信环境中管理随机接入数据信道的设备和方法。 实现上行链路(UL)随机接入(RA)信道以将数据发送到接入点(AP),而不需要在下行链路(DL)上发送用于UL定时调整的UL分配准许消息。 移动台(MS)向AP发送选择的序列以指示正在请求RA数据传输。 用于UL RA数据传输的无线电资源的位置和数量由最初由MS发送的RA序列的选择确定。 如果UL定时尚未建立,则AP能够通过从MS导出初始RA请求序列传输的偏移来确定UL RA数据传输的定时。
