Patent ID: 7139251

Claim:
A method of managing time division duplexing across plural channels, including the steps of: establishing a communication session between two or more stations using a duplex protocol, said stations including some combination of customer premises equipment and at least one base station controller each having a system identification code (SID); defining one or more classes of service for data flows to and from each one of said stations, whereby said classes include (1) a guaranteed transfer rate, and (2) a best efforts transfer rate; assigning a priority for transmission of data based on some combination of said classes of service and a data time-stamp, said time-stamp indicative of the age of said data; and scheduling data for transmission based on said priority; wherein said step of scheduling further includes the steps of generating different classes of upstream and down stream data flows, said data flows including class of service and quality of service parameters; selecting data for transmission based on the variable symbol rates and constellation types of said customer premises equipment; and maximizing transmission of each time division duplex frame at the physical wireless and media access control levels.
