一种随机接入方法、系统及终端设备技术方案

本发明专利技术实施例提供了一种随机接入方法、系统及终端设备，涉及通信领域，方法：第一站点STA在接收接入节点AP广播的第一指示帧后，确定当前接入时段的待接入信道、侦听起点、数据包发送起点、竞争信号待发送起点；侦听起点早于数据包发送起点，当竞争信号待发送起点位于侦听起点与数据包发送起点之间且分别与侦听起点和数据包发送起点之间间隔至少一个时隙时，在第一时隙对待接入信道进行侦听；第一时隙为侦听起点与竞争信号待发送起点之间间隔的时隙中靠近竞争信号待发送起点的时隙；当侦听结果显示待接入信道未被占用时，从竞争信号待发送起点开始在待接入信道上广播竞争信号，直到数据包发送起点结束，从数据包发送起点开始通过待接入信道发送数据包。

A random access method, system and terminal equipment

The embodiment of the invention, a system and a terminal device of a random access method, provided that relates to the communication field, methods: the first site STA in the first indication frame receiving AP radio access node, determining the current access time to access the channel, and packets interception starting point starting point, competition signal to be transmitted starting point; listening starting point as early as the packet signal to be transmitted as starting point, competition starting point is located between the starting point and packet interception and interception starting point starting point and packet interval of at least one slot between the starting point, the interception in the first time slot to access channel slot; near the starting point of the competition signal to be transmitted for the first time slot slot and interception starting point the competition between the starting point for the signal sending interval; when listening to show access channel is not occupied, from the signal to be transmitted from the competition The point begins to broadcast the competing signal on the access channel until the end of the packet sending point starts, and the packet is sent from the starting point of the packet delivery to the access channel.
