Use of orthogonal or near orthogonal codes in reverse link

A subscriber unit for communicating with a network device, wherein the network device is in communication, during a time slot, with a first plurality of subscriber units each associated with a sequence that is different from a sequence of other subscriber units of the first plurality of subscriber units, and with a second plurality of subscriber units each associated with a sequence that is also associated with other subscriber units of the second plurality of subscriber units and an orthogonal sequence that is different from an orthogonal sequence of others of the second plurality of subscriber units, the subscriber unit comprising:

• an antenna;
• and
• transmitter circuitry operatively coupled to the antenna and configured to transmit a wireless signal in the time slot;
• wherein the subscriber unit is one of the second plurality of subscriber units;
• and
• wherein the wireless signal is generated using the orthogonal sequence and the sequence that also associated with the other subscriber units of the second plurality of subscriber units.

A wireless network device comprising:

• at least one antenna;
• and
• receiver circuitry operatively coupled to the antenna and configured to receive signals from a first plurality of subscriber units in a time slot;
• and
• the receiver circuitry further configured to receive signals from a second plurality of subscriber units in the time slot;
• wherein the signal received from each of the first plurality of subscriber units comprises data combined with a sequence that is different from a sequence associated with other subscriber units of the first plurality of subscriber units and the data is not combined with an orthogonal sequence;
• and
• wherein the signal received from each of the second plurality of subscriber units comprises an orthogonal sequence that is different from an orthogonal sequence of other subscriber units of the second plurality of subscriber units, the received signal from each of the second plurality of subscriber units having a same sequence as the other subscriber units of the second plurality of subscriber units.

A method comprising:

• receiving signals, by a wireless network device, from a first plurality of subscriber units and a second plurality of subscriber units, in a time slot;
• wherein the signal received from each of the first plurality of subscriber units comprises data combined with a sequence that is different from a sequence of others of the first plurality of subscriber units and the data is not combined with an orthogonal sequence;
• and
• wherein the signal received from each of the second plurality of subscriber units comprises an orthogonal sequence 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 sequence as the others of the second plurality of subscriber units.
