<p>A method and device for channel access control are disclosed in the embodiments of the present application. The method comprises: receiving a data packet sent by a sender; determining, according to the data packet, whether the sender accesses a channel in accordance with a period T; and, when the sender accesses the channel in accordance with the period T, performing a back-off at a time of t1+nT, wherein n is a positive integer, the initial value of n is 1, t1 is a reception time of the data packet. In the method, for a terminal located within the coverage of the sender, when the sender sends the data packet at the time of t1, the terminal can receive the data packet and can determine, by utilizing the received data packet, whether the sender accesses the channel in accordance with the period T, and perform the back-off at the time of t1+nT when it is determined that the sender accesses the channel in accordance with the period T; further, the sender can be ensured to access the channel periodically and accomplish a periodic service data transmission.</p> |
