Abstract
A statistical time division multiplexer facilitates distribution of data from various sources through a wireless transmission system to a plurality of subscriber stations within a cell reception area. Controlled logical token passing governs a variable token interval for data transmission from each buffer, associated in a base station with a respective receiving subscriber station, in turn to form a common data stream. Each subscriber may be assigned a minimum transmission time interval during which data, if present in the associated buffer, will be transferred. Data may be fed from the buffers in successive time intervals at bit rates that can vary from interval to interval. Variations of data transmission rate and token interval for each subscriber can be separately controlled on the basis of both presubscribed levels and current quality of service levels of the radio link. Channel quality and/or bit error rate for each channel may be fed back dynamically from the user for each token interval.
