Abstract
A method for providing access by secondary stations (12, 14, 16) to a shared transmission medium, maintains a list of secondary stations (12, 14, 16). A poll is transmitted poll by a primary station (10) to one of the secondary stations (12, 14, 16). The secondary station (12, 14, 16) waits for a poll, examines the transmission allocation, determines if there is congestion and transmits, along with the data in response to the poll, information regarding congestion. A system for providing such access includes a primary station (10) and a plurality of secondary stations (12, 14, 16). The primary station includes a polling controller (30), a receiver (32), a transmitter (34), a summer (36), a secondary station poll list database (38) and a data traffic controller (40).
