2. Comments #17 Comment #17 Resolution
Can this be done with an information element? Also, there are some updates to the frame format that need to be reviewed.
Resolution
Yes. Capability IE can be used for exchanging UEP capability (done).
Unified UEP capable field in Capability IE

3. UEP Capable in Capability IE
Unified UEP field in Capability IE based on IEEE /0174r0 presented by J.G
7 bit UEP capable field in Capability IE is sufficient, no commands or extra IEs required
2bits are assigned to identify PHY (SC(00)/HSI-OFDM(01)/AV-OFDM(11))
UEP field (3bits); Refers to the DEVs capability as a receiver
000 – no UEP capability
001 – Type 1 capable
010 – Type 2 capable
011 – Type 3 capable with MCS only
100 – Type 3 capable with skewed constellation only
101 – Type 3 capable with MCS and skewed constellation
– Reserved
UEP MCS (2bits)
00 – QPSK-outer FEC(RS) (SC/HSI-OFDM) or UEP (AV-OFDM)
01 – QPSK/16QAM-outer FEC(RS) (SC/HSI-OFDM)
or UEP/MSB only retransmission (AV-OFDM)
10 – QPSK-no outer FEC
11 - Reserved
