2.2 About IEEE 802.11ad
This chapter provides basic information of the IEEE 802.11ad technology. For related
information and further reading, see IEEE Std 802.11ad™-2012 standard specification.
Directional multi-gigabit (DMG) PHY modes
The R&S SMW-K141 option supports two modulation modes:
●DMG control PHY, see Chapter 2.2.1, "DMG control PHY mode", on page 14.
●DMG single carrier (SC) PHY, see Chapter 2.2.2, "DMG SC PHY", on page 14.
●DMG OFDM PHY is not supported.
All DMG PHYs use the same PPDU format, but they differ in how the individual fields
are defined as well as in the coding and modulation that is used.
DMG PPDU format
Figure 2-1: DMG PPDU format
The DMG PPDU consists of the following common parts:
●Preamble
The preamble consists of the short training field (STF) and the channel estimation
(CE) field. It is required in every packet. It supports the receiver during automatic
gain control (AGC), when recognizing the packet and estimating the frequency off-
set. The receiver can also use the known CE field to estimate the channel.

●Header
The header is different for every PHY and contains additional important information
for the receiver, such as the modulation mode (MCS), the length of the data field or
a checksum.
●Data
This part is used to transmit the actual data with different modulations (MCS). The
length of the field varies (number of bytes/octets).
●Training for beamforming (TRN)
An optional field that includes beamforming information and can be appended to all
packets.
2.2.1 DMG control PHY mode
The control mode is used to exchange signaling and/or control messages to establish
and monitor connections between the various devices. Support for this mode is there-
fore mandatory for all devices.

2.3 About IEEE 802.11ay
This chapter provides basic information of the IEEE 802.11ay technology. For related
information and further reading, see IEEE Std 802.11ay™-2021 standard specification.
Enhanced directional multi-gigabit (EDMG) PHY modes
The EDMG PHY modes are EDMG control, EDMG single carrier (SC) and EDMG
orthogonal frequency division multiplexing (OFDM) modes. The R&S SMW-K177
option supports EDMG single carrier (SC) PHY, see Chapter 2.3.5, "EDMG and non-
EDMG SC mode", on page 23.
The EDMG PHY adds support for multiple space-time streams, downlink multi-user
(MU) transmissions and PPDU transmissions with multiple channel bandwidths. These
bandwidths include 4.32 GHz, 6.48 GHz, 8.64 GHz, 2.16+2.16 GHz, and
4.32+4.32 GHz.
The channels making up a 2.16+2.16 GHz and 4.32+4.32 GHz PPDU transmission
can be contiguous or noncontiguous. The maximum number of spatial streams per
STA is eight. An MU PPDU transmission supports up to eight STAs. For

Table 2-2.
TRN Training sequence field TRN-R (receive) or TRN-T (transmit) subfields
EDMG preamble
Like the EDMG PPDU, the EDMG preamble has a non-EDMG portion and an EDMG
portion. For a single PPDU transmission, the fields of the non-EDMG portion and the
EDMG-Header-A field of the EDMG portion form the pre-EDMG modulated field, see
Figure 2-4. The subsequent fields in the PPDU form the EDMG modulated fields.
For an EDMG A-PPDU transmission, the fields of the non-EDMG portion and the
EDMG-Header-A field of the EDMG portion of the first EDMG PPDU form the pre-
EDMG modulated fields. Subsequent fields in the EDMG A-PPDU form the EDMG
modulated fields. For 4.32 GHz, 6.48 GHz and 8.64 GHz EDMG PPDU transmissions,
the pre-EDMG modulated fields are transmitted using the non-EDMG duplicate format.
The pre-EDMG modulated fields of each secondary channel have a relative delay com-
pared to corresponding fields of the primary channel. This delay is between zero (inclu-
sive) and the chip time duration Tc (inclusive). The relative delay of each secondary
channel transmission can differ between channels but is maximum Tc.
The L-Header field further defines the content of the Data field. Bit values "B46" and
"B37" distinguish if the data is part of a DMG MPDU/A-MPDU or an EDMG MPDU/A-
MPDU, see Table 2-2.

B46 B37 Data field content
0 0 DMG MPDU
0 1 DMG A-MPDU
1 0 EDMG MPDU
1 1 EDMG A-MPDU
EDMG-Header-B field
The EDMG-Header-B is transmitted only in EDMG MU PPDUs and on a per STA
basis. The EDMG-Header-B field is defined in the table Table 2-3. The value of the
Spoofing Error Length Indicator subfield within all EDMG-Header-B fields present in an
EDMG MU PPDU is the same. The transmitter sets reserved bits in the EDMG-
Header-B field to 0 so that the receiver ignores them.

Superimposed Code
Applied
1 36 Corresponds to TXVECTOR parameter LDPC_SUPERIM-
POSED.
If the LDPC code rate is 7/8 and this field is set to 0, it
indicates puncturing code with codeword length 624 or
1248 is applied. If the LDPC code rate is 7/8 and this field
is set to 1, it indicates that superimposed code with code-
word length 672 or 1344 is applied.
If the EDMG-MCS field indicates a value of 13 and the π/
2-8-PSK Applied field is 1, then this field indicates the 7/8
code. This code is employed in the encoding procedure
with codeword shortening to achieve the effective code
rate of 5/6. In all other cases, this field is reserved.
Short/Long LDPC 1 37 Corresponds to the TXVECTOR parameter
LDPC_CW_LENGTH. Indicates the LDPC codeword
length used in the PSDU.
Set to 0 for LDPC codeword of length 672, 624, 504, or
468. Set to 1 for LDPC codeword of length 1344, 1248,
1008, or 936.
STBC Applied 1 38 Corresponds to the TXVECTOR parameter STBC.
If set to 1, indicates that STBC was applied at the trans-
mitter. Otherwise, set to 0. If set to 1, the DCM BPSK
Applied and the Phase Hopping fields are set to 0.
NUC Applied 1 39 Corresponds to the TXVECTOR parameter NUC_MOD.
If this field is set to 1, π/2-64-NUC is applied at the trans-
mitter for the MCSs indicated by the Base MCS and Differ-
ential EDMG-MCS fields, if supported.
If an indicated MCS does not support π/2-64-NUC, then π/
2-64-QAM uniform constellation is applied for this particu-
lar MCS. If set to 0, π/2-64-QAM uniform constellation is
applied for MCSs signaled in the Base MCS and Differen-
tial EDMG-MCS fields.
π/2-8-PSK Applied 1 40 Corresponds to TXVECTOR parameter PSK_APPLIED.
If this field is set to 1, π/2-8-PSK with corresponding
LDPC shortening code with rates 2/3 or 5/6 is applied at
the transmitter for MCS 12 or 13. The EDMG-MCS field
indicates the MCS.
If set to 0, π/2-16-QAM constellation with regular LDPC
code with rates 1/2 or 5/8 is applied at the transmitter for
MCS 12 or 13.

Subfield Nbits Start bit Description
Spoofing Error Length
Indicator
1 41 If set to 0 in an EDMG OFDM PPDU, indicates that the
spoofing error is smaller than TOFDM-SYM. This error is
defined as the difference between the PPDU duration
based on L-Header and the actual PPDU duration.
TOFDM-SYM = TDFT + TGI, TDFT is the OFDM IDFT/DFT period
and TGI is the guard interval duration. The durations are
determined by bits B2 and B3 of the Last RSSI field within
the L-Header of the PPDU.
Otherwise, if set to 1 in an EDMG OFDM PPDU, indicates
that the spoofing error is greater than or equal to TOFDM-
SYM. For an EDMG SC PPDU, this field is reserved.
Beamformed 1 42 Corresponds to the TXVECTOR parameter BEAM-
FORMED.
If set to 1, indicates active digital beamforming. Set to 0
otherwise.
Number of Transmit
Chains
3 43 Corresponds to TXVECTOR parameter
NUM_TX_CHAINS.
The value of this field plus 1 indicates the number of trans-
mit chains used in the transmission of the PPDU. The
value of the field plus 1 also indicates the total number of
orthogonal sequences in a TRN field.
This field is reserved when the EDMG TRN Length field is
0, or when the EDMG Beam Tracking Request field is 1
and the PPDU is an EDMG BRP-RX PPDU.

EDMG A-PPDU format
An EDMG A-PPDU is a concatenation of EDMG PPDUs and is available for single
users (SU MPDU) only. Figure 2-5 shows the EDMG A-PPDU format and all possible
fields.

The first PPDU ("1st EDMG PPDU") includes the fields L-STF, L-CEF, L-Header,
EDMG-Header-A, EDMG-STF, EDMG-CEF, and Data. Each subsequent PPDU
includes EDMG-Header-A and Data fields only. The TRN field, if present, is appended
only once at the end of an EDMG A-PPDU.
Transmission of these fields within an EDMG A-PPDU depends on the values of NCB
(number of contiguous 2.16 GHz channels) and NSTS (number of space-time streams

the PSDU transmitted in the Data field.
2.3.2 Channelization
EDMG stations (STAs) use the channelization as in Figure 2-6.
Figure 2-6: EDMG STA channelization
The center of the trapezoid shows the channel number defining the particular channel
location. The support of the 2.16 GHz channel number 2, and the 4.32 GHz channel
number 10 with channel number 2 as a primary channel is mandatory. The support of
other channels is optional.
2.3.3 MIMO and beamforming
SU-MIMO beamforming
An EDMG STA is SU-MIMO capable if the SU-MIMO Supported subfield of the Beam-
forming Capability subelement in the EDMG Capabilities element of the STA is 1. The
SU-MIMO beamforming protocol supports beamforming training for subsequent trans-
mission and reception of multiple spatial streams between an SU-MIMO capable initia-
tor and an SU-MIMO capable responder.
The SU-MIMO beamforming protocol enables the determination of transmit antenna
settings and the corresponding receive antenna settings. Determination is for simulta-
neous transmission of multiple spatial streams from the initiator to the responder or
