1. A wireless communication system, comprising:

  • a central access point (CAP), determining current physical frame structure based on scheduled transmission resources, and transmitting information for indicating current physical frame structure in the current physical frame;

    wherein the determining current physical frame structure comprises;

    configuring leader sequence used for synchronization for current physical, and system information channel used for sending information of indicating current physical frame structure;

    wherein said CAP sends leader sequence, and information of indicating current physical frame structure in system information channel;

    or configuring leader sequence used for synchronization for current physical, and system information channel used for sending information of indicating current physical frame structure; and

    configuring selectively at least one of a plurality of channels for current physical frame;

    wherein said CAP sends said leader sequence, and information of indicating current physical frame structure in system information channel; and

    transmitting/receiving in the channel that is selectively configured; and

    at least one station (STA) communicating with said CAP, according to information for indicating current physical frame structure in physical frame, determining structure of current physical frame;

    wherein a length of each physical frame is unfixed, and the length of current physical frame is the sum of duration of each channel in the current physical frame.
