Abstract
Systems and methods of performing communication via television high throughput (TVHT) bandwidth channels are disclosed. Values of one or more physical layer parameters for use in communication via TVHT parameters are also defined. A short inter-frame spacing (SIFS) time is 120 microseconds (μs) for a 6 megahertz (MHz) or a 7 MHz bandwidth channel, and is 90 μs for an 8 MHz bandwidth channel. The parameters also include a clear channel assessment (CCA) time of 15 μs for a 6 MHz or 7 MHz bandwidth channel and 11.25 μs for an 8 MHz bandwidth channel. Additional parameters, such as compliance with a spectral flatness constraint, transmit center frequency tolerance, symbol clock frequency tolerance, transmitter center frequency leakage, transmitter constellation error, and non-HT duplicate transmission are also defined (e.g., for inclusion into a standard, such as Institute of Electrical and Electronics Engineers (IEEE) 802.11af).
