Systems and methods for multiuser interleaving and modulation

A wireless transmit/receive unit (WTRU) comprising:

• a transceiver configured to transmit a plurality of bits to an access point (AP);
• the transceiver further configured to receive a constellation symbol from the AP,
• wherein the constellation symbol comprises a plurality of indications of bits,
• wherein each indication of the plurality of indications of bits is associated with a respective WTRU of a plurality of WTRUs,
• wherein each indication of the plurality of indications of bits is associated with a weight,
• wherein a first weight associated with a first indication of the plurality of indications of bits is different than a second weight associated with a second indication of the plurality of indications of bits, and
• wherein the plurality of indications of bits comprises indications of bits modulated at a multi-user constellation bit division multiple access modulator (MU-CBDMAM).
