Abstract
A wireless transmit/receive unit (WTRU) may receive a constellation symbol that includes indications that each are associated with a respective WTRU of a plurality of WTRUs. The WTRU may determine that a first weight associated with a first indication of the indications is different than a second weight associated with a second indication of the indications. The indications may comprise indications of bits modulated at a multi-user constellation bit division multiple access modulator (MU-CBDMAM).
Claims20
A method performed by a wireless transmit/receive unit (WTRU), the method comprising:
- receiving, from an access point (AP), a constellation symbol, wherein the constellation symbol includes a plurality of indications for multi-user modulation, and each indication is associated with a respective WTRU of a plurality of WTRUs;
- and
- determining, by the WTRU, that a first error protection weight associated with a first indication of the plurality of indications is different than a second error protection weight associated with a second indication of the plurality of indications;
- wherein the plurality of indications comprise bits modulated by the AP using multi-user constellation bit division multiple access modulation (MU-CBDMAM).
A wireless transmit/receive unit (WTRU) comprising:
- a transceiver configured to receive, from an access point, a constellation symbol, wherein the constellation symbol includes a plurality of indications for multi-user modulation, and each indication is associated with a respective WTRU of a plurality of WTRUs;
- and
- a processor configured to determine that a first error protection weight associated with a first indication of the plurality of indications is different than a second error protection weight associated with a second indication of the plurality of indications;
- wherein the plurality of indications include bits modulated by the AP using multi-user constellation bit division multiple access modulation (MU-CBDMAM).
