Abstract
In accordance with various aspects of the disclosure, a method and apparatus are disclosed that includes aspects of a controller configured to create a VHT frame that is arranged to include information relating to a modulation and a coding scheme with which a data portion of the VHT frame is modulated and encoded; and a transmitter configured to transmit the VHT frame to one or more STAs.
Claims10
An apparatus comprising:
- a wireless communications controller configured to create a frame that is arranged to include information indicating a modulation and coding scheme with which a data portion of the frame is modulated and encoded;
- and
- a transmitter configured to transmit the frame to one or more STAs,
- wherein the frame is to have a legacy training field followed by a VHT signal field;
- wherein the frame is a Greenfield format frame.
2 more elements
A method comprising:
- creating a frame that is arranged to include information indicating a modulation and coding scheme with which a data portion of the frame is modulated and encoded;
- and
- transmitting the frame to one or more STAs,
- wherein the frame is to have a legacy training field followed by a VHT signal field;
- wherein the frame is a Greenfield format frame.

An apparatus comprising:
- a wireless communications controller configured to create a frame that is arranged to include information indicating a modulation and coding scheme with which a data portion of the frame is modulated and encoded;
- and
- a transmitter configured to transmit the frame to one or more STAs,
- wherein the frame is to have a VHT signal field which follows an HT training field.
1 more element
An apparatus comprising:
- a receiver configured to receive a wireless frame comprising an HT training field and a VHT signal field following the HT training field;
- and
- a controller configured to check CRC validity of the VHT-SIG field to process the received wireless frame as a VHT Greenfield format frame.
An apparatus comprising:
- a receiver configured to receive a wireless frame comprising a legacy signal field followed by a VHT signal field;
- and
- a controller configured to check constellation rotation and CRC validity of the VHT-SIG field to process the received wireless frame as a VHT mixed-format frame.
