Then 802.11n defines 77 kinds of MCS, and call number is 0～76, then the value more than 76 may be considered
Insignificant value, then completing the instruction in MFB/OM domains and its type can use following methods：
When the value of 7bits information fields is 0～76, represent that the domain is MFB domains, that is, carry link adaptive
Answer announcement information；When the domain highest order two bit all be 1 when (now, the value of 7bits be more than or
Equal to 96), then it represents that the low 5bits in the domain carries reception pattern announcement information, specifically, including connecing
Bandwidth BW (2bits) and Nss (3bits) in receipts pattern, thus, by MFB/OM subdomains
Span is automatically performed type instruction.
Again for example, for the HTC domains of VHT classifications, MFB/OM domains are multiplexed original MFB domains
(15bits, including the SNR of MCS, 6bits of Nss, 4bits of BW, 3bits of 2bits),
Then 802.11ac defines 10 kinds of MCS, and the value in MCS domains is retention more than 9, then complete
The instruction of MFB/OM subdomains and its type can use in the following manner：
Mode one：The value of MCS or SNR is set to into retention, for example, MCS is set to into 15,
Then represent that BW and Nss domains are reception pattern announcement information, notify new reception bandwidth and spatial stream number；
