Abstract
Methods and wireless communication devices for mode classification include configuring the wireless communication device to receive a wireless frame transmitted over an operating channel bandwidth, determine a frequency domain signal representing a plurality of symbols carried in the wireless frame, estimate a primary channel bandwidth for the wireless frame from the frequency domain signal, determine a bandwidth field in a signal field of the wireless frame, compare the primary channel bandwidth with the operating channel bandwidth, and a mode used to transmit the wireless frame based on the bandwidth field and the comparing result.
Claims20
A mode classification method performed by a wireless communication device operating in a wireless network, the method comprising:
- receiving a wireless frame transmitted over an operating channel bandwidth;
- determining a frequency domain signal representing a plurality of symbols carried in the wireless frame;
- estimating a primary channel bandwidth for the wireless frame from the frequency domain signal;
- determining a bandwidth field in a signal field (SIG) of the wireless frame;
- comparing the primary channel bandwidth with the operating channel bandwidth;
- and
- determining a mode used to transmit the wireless frame based on the bandwidth field and the comparing result, wherein the wireless frame is processed according to the determined mode.
A wireless communication device operating in a wireless network, comprising:
- a Radio Frequency (RF) receiver receiving a wireless frame transmitted over an operating channel bandwidth;
- a processor, communicatively coupled to the RF receiver;
- one or more memory banks, communicatively coupled to the processor and storing processor readable codes that, when executed by the processor, are configured for:
- determining a frequency domain signal representing a plurality of symbols carried in the wireless frame;
- estimating a primary channel bandwidth for the wireless frame from the frequency domain signal;
- determining a bandwidth field in a signal field (SIG) of the wireless frame;
- comparing the primary channel bandwidth with the operating channel bandwidth;
- and
- determining a mode used to transmit the wireless frame based on the bandwidth field and the comparing result;
- and
- a demodulator, operating in a duplicate mode when the determined mode is a duplicate full band mode or a duplicate subband mode.
