Abstract:
1. A method for scheduling a transmission of at least one data stream in a wireless communications network having at least one access point and at least one station, the method comprising: receiving by the at least one access point a request to send said at least one data stream for transmission from the at least one station; granting by the at least one access point said request to send said at least one data stream; transmitting by the at least one station a medium access control (MAC) frame comprised of a set of parameters defining the characteristics of said at least one data stream; and calculating by the access point service and transmission times according to a schedule algorithm utilizing said parameters, wherein calculating the service and transmission times includes determining a Service Interval (SI) and a servicing time (TXOP) for said at least one data stream by: calculating a minimum interval of all Maximum Service Intervals for said at least one data stream, and calculating the SI by choosing a number that is lower than said calculated minimum interval and is a submultiple of a beacon interval.
