<P>PROBLEM TO BE SOLVED: To provide a modem that provides efficient use of wireless network bandwidth in the presence of multi-user interference and noise. <P>SOLUTION: A method includes indicating the beginning of a contention-free period, and simultaneously transmitting on a single channel a first set of polling signals. Each polling signal corresponds to a particular terminal included in a first set of terminals included in a network. The method proceeds with receiving two or more simultaneous responses from the first set of polled terminals, and recovering each of the two or more simultaneous responses using co-channel demodulation capabilities of an AP element. The method may further include transmitting clear-to-send messages to any terminals requesting to send data, as indicated by received responses. <P>COPYRIGHT: (C)2013,JPO&INPIT |
