Introduction
Non-uniform constellations (NUCs) have been shown to provide increased performance compared to uniform constellations (UCs) [1]-[4]
11ay SFD indicates support for NUC
“A 64-point non-uniform constellation shall be included in the 11ay specification”, motioned in July 2016
However, there is no signaling for NUCs defined
This presentation shows a NUC signaling and a NUC capabilities proposal

Aspects to consider
NUC applies to higher order MCS only
NUC gain is significant for constellation orders greater or equal than 16-QAM
NUC does not replace uniform constellation (UC)
EDMG devices will support UC for backwards compatibility
All EDMG modes of operation shall benefit of NUC
Decision on number of distinct NUCs and signal points not yet made

Capabilities Proposal
The support of non-uniform constellation requires indication in EDMG capabilities
Addition of NUC capability information to EDMG capabilities
NUC implementation complexity is asymmetric between Tx and Rx
A NUC mapper is much simpler than a NUC demapper
We propose that NUC capability information shall distinguish between NUC transmission and NUC reception

Signaling Proposal
A single bit in headers indicates the use of non-uniform constellation
Add a “NUC indication” to EDMG-header-A
Add a “NUC indication” to EDMG-header-B
Users may have different NUC capabilities
The “NUC indication” consists of a single bit
If bit is set, NUC is used by transmitter
It is valid for each addressed spatial stream (MIMO)
The actual code rate and constellation size is signaled with the EDMG-MCS subfield in each header
If the entry in a particular EDMG-MCS subfield does not support NUC, uniform constellation shall be applied

Signaling Proposal (cont.)
Advantages of NUC signaling in headers
Flexible design independent of number of NUCs
Agreed MCS table unchanged
Signaling independent of actual mode of operation
Same signaling for SU-SISO, SU-MIMO, MU-MIMO, MU-FDMA, channel aggregation
Same signaling could also be applied in OFDM headers
NUC could also be part of MCS table, however
MCS table would change
NUC would cause additional and redundant entries
Limited space in MCS table for future enhancements (e.g. >64-QAM)
More complex signaling of capabilities
MCS signaling for SU-MIMO (>4 SS) needs to be revisited

Addition of a single bit in EDMG header-A and header-B
Signaling is invariant with respect to 11ay modes of operation
Addition of capability information for non-uniform constellation to the EDMG capabilities
Capability information shall distinguish between NUC transmission and NUC reception
