Scheduling for links having changing parameters

A base station controller communicating with at least one customer premises equipment over a communication link, said base station controller comprising a transceiver and a controller that performs 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 said base station controller, wherein each said customer premises equipment has an associated 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 includes performing 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.

A computer-readable memory storing information including computer-executable instructions, said instructions executed by a processor to manage time division duplexing across plural channels, the instructions comprising:

• 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 includes performing 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.
