EDMG SC mode Signal parameters General This subclause defines the main EDMG SC signal parameters for 2.16 GHz, 4.32 GHz, 6.48 GHz, 8.64 GHz PPDU transmissions. Timing related parameters Table 56 a summary of the EDMG SC mode timing related parameters. Table 56—EDMG SC mode timing related parameters Parameter Value NCB = 1 NCB = 2 NCB = 3 NCB = 4 Fc: SC chip rate 1.76 GHz 3.52 GHz 5.28 GHz 7.04 GHz Tc: SC chip time 0.57 ns 0.28 ns 0.19 ns 0.14 ns NDFT: DFT size 512 1024 1536 2048 TDFT: SC IDFT/DFT period 0.291 µs 0.291 µs 0.291 µs 0.291 µs TGI short: short guard interval duration 18.18 ns 18.18 ns 18.18 ns 18.18 ns TGI normal: normal interval duration 36.36 ns 36.36 ns 36.36 ns 36.36 ns TGI long: long guard interval duration 72.72 ns 72.72 ns 72.72 ns 72.72 ns Editor: change the text as below, page 301, Table 67, [2] Number of symbols (constellation points) per SC symbol block; depends on the GI type as defined in. Editor: change the text as page 302, line 4, [2] defines the number of symbols (constellation points) per SC symbol NSPB, for different types of GI.

Editor: change the text as below, page 284, line 6, [2] Figure 130—Transmitter block diagram for EDMG of an MU PPDU transmission CID 1930, 1932, 2177 Comment: It is not clear what this sentence means: "However, transmitter keeps the common space-time streams numeration over all users." Figure 130 shows that, for each user, Nss and N_STS <=2. But there is no description in the test. No reference to EDMG-Header-B in text Proposed change: Explain or rephrase this sentence: "However, transmitter keeps the common space-time streams numeration over all users." Add a sentence to indicate Nss and <=2 Change text to: "The PPDU encoding uses seed values in EDMG-Header-B as defined in 30.5.6, and......user." Resolution: Revised. Editor: change the text as below, page 283, line 19, [2] Figure 130 shows the transmitter blocks used to generate the EDMG portion of an MU PPDU. The EDMG-STF and EDMG-CEF fields are generated using the Preamble builder block. The TRN field is generated using TRN builder block. The EDMG-Header-B and Data field of the PPDU are generated using scrambler, LDPC encoder, constellation mapper, interleaver, and GI insertion blocks. The PPDU encoding uses seed value defined in and has independent flow per user.If STBC encoder is applied, then a single spatial stream is mapped to two space-time streams as defined in 30.5.9.5.3. The NSTS space-time streams are further mapped to NTX transmit chains, where NSTS ≤ NTX.

If the LDPC code rate is 7/8 and this field is set to one, it indicates that superimposed code with codeword length 672 or 1344 is applied. In all cases, this field is reserved.
