Claim Text:
1. A wireless network device comprising: circuitry configured to receive signals and recover data from a first plurality of subscriber units in a time interval including at least one time slot; and circuitry configured to receive signals and recover data from a second plurality of subscriber units in the time interval; wherein the received signal from each of the first plurality of subscriber units comprises a pseudo noise (PN) sequence that is different from a PN sequence of others of the first plurality of subscriber units; wherein the received signal from each of the second plurality of subscriber units comprises an orthogonal sequence that is different from an orthogonal sequence of others of the second plurality of subscriber units, the received signal from each of the second plurality of subscriber units having a same PN sequence as the others of the second plurality of subscriber units; and wherein received signals from the second plurality of subscriber units comprise an orthogonal sequence which is not present in the received signals from the first plurality of subscriber units; and the wireless network device further comprising circuitry configured to transmit to each subscriber unit of the second plurality of subscriber units configuration information for use by that subscriber unit in determining the different orthogonal sequence of that subscriber unit.
