Systems and methods for multiuser interleaving and modulation
Methods, systems, and apparatuses are disclosed for transmitting a plurality of bits to an access point (AP) and receiving constellation symbol from the AP. A constellation symbol may include a plurality of indications of bits. Each indication of the plurality of indications of bits may be associated with a respective wireless transmit/receive unit (WTRU) of a plurality of WTRUs. The plurality of indications of bits may include indications of bits modulated at a multi-user constellation bit division multiple access modulator (MU-CBDMAM).
1. A method comprising:
transmitting, from a wireless transmit/receive unit (WTRU), a plurality of bits to an access point (AP);
receiving, at the WTRU, 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).
2. The method of claim 1 , wherein the plurality of indications of bits comprises indications of bits modulated at one of an open loop MU-CBDMAM or a closed loop MU-CBDMAM.
3. The method of claim 1 , wherein each indication of the plurality of indications of bits is associated with a weighting that differs from weightings associated with each other indication of the indications of bits.
4. The method of claim 1 , wherein the constellation symbol is associated with one of a uniform constellation or a non-uniform constellation.
5. The method of claim 1 , further comprising receiving a first MU-CBDMAM information element (IE) indicating a capability of the AP.
6. The method of claim 5 , wherein the first MU-CBDMAM IE is comprised in a beacon.
7. The method of claim 1 , further comprising transmitting an association request to the AP comprising a second MU-CBDMAM IE.
8. The method of claim 1 , further comprising receiving a first data frame associated with one of an open loop MU-CBDMAM or a closed loop MU-CBDMAM.
9. The method of claim 1 , further comprising transmitting a feedback control frame to the AP comprising that comprises at least one of an acknowledgement (ACK), an indicator of channel state information (CSI), and an indication of a signal-to-noise ratio (SNR).
10. The method of claim 1 , further comprising receiving an MU-CBDMAM transmission opportunity (TXOP) end frame.
11. 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).
12. The WTRU of claim 11 , wherein the plurality of indications of bits comprises indications of bits modulated at one of an open loop MU-CBDMAM or a closed loop MU-CBDMAM.
13. The WTRU of claim 11 , wherein each indication of the plurality of indications of bits is associated with a weighting that differs from weightings associated with each other indication of the indications of bits.
14. The WTRU of claim 11 , wherein the constellation symbol is associated with one of a uniform constellation or a non-uniform constellation.
15. The WTRU of claim 11 , wherein the transceiver is further configured to receive a first MU-CBDMAM information element (IE) indicating a capability of the AP.
16. The WTRU of claim 15 , wherein the first MU-CBDMAM IE is comprised in a beacon.
17. The WTRU of claim 11 , wherein the transceiver is further configured to transmit an association request to the AP comprising a second MU-CBDMAM IE.
18. The WTRU of claim 11 , wherein the transceiver is further configured to receive a first data frame associated with one of an open loop MU-CBDMAM or a closed loop MU-CBDMAM.
19. The WTRU of claim 11 , wherein the transceiver is further configured to transmit a feedback control frame to the AP comprising that comprises at least one of an acknowledgement (ACK), an indicator of channel state information (CSI), and an indication of a signal-to-noise ratio (SNR).
20. The WTRU of claim 11 , wherein the transceiver is further configured to receive an MU-CBDMAM transmission opportunity (TXOP) end frame.
