CHANNEL ALLOCATION MANAGEMENT METHOD FOR TRANSFERRING ASYNCHRONOUS DATA, ASYNCHRONOUS DATA TRANSFERRING METHOD, AND APPARATUS THEREOF
First Claim
1. A method of managing channel allocation for asynchronous data transmission, the method comprising:
- broadcasting a first superframe for a first beacon period, the first superframe containing a control section and a data slot section;
receiving a request frame from at least one wireless device belonging to a network via the control section, the request frame requesting an addition of a data slot for asynchronous data transmission;
transmitting a response frame to the at least one wireless device via the control section in response to the request frame; and
broadcasting a second superframe for a second beacon period, the second superframe containing information regarding the requested data slot, if the requested data slot is added, to the at least one wireless device.
