Abstract: Arbitration between two wireless protocols in a wireless device. The wireless device may include first wireless protocol circuitry, configured to receive and process first signals according to a first wireless protocol and second wireless protocol circuitry, configured to receive and process second signals according to a second wireless protocol. The wireless device may also include coexistence circuitry. The coexistence circuitry may be configured to receive a request from the first wireless protocol circuitry to perform transmission or reception and arbitrate the requested transmission or reception between the first wireless protocol circuitry and the second wireless protocol circuitry. The decision may be based on current or future priority information, current configuration, or other factors. The coexistence circuitry (or other circuitry) may be configured to determine position of switches controlling antennas or transmission using shared or unshared antennas (or chains). The two wireless protocols may be WLAN and Bluetooth.

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).

Abstract: ABSTRACT A method of identifying radar in a wireless device includes detecting an event corresponding to receipt of a signal by the wireless device. The event can include an analog to digital converter (ADC) saturation, a radio frequency (RF) saturation, and/or an ADC power high condition. Notably, the gain change in the wireless device is delayed for a first predetermined time period. Data preceding the event for the first predetermined time period can be buffered. A first low-resolution fast Fourier transform (FFT), wherein low-resolution FFTs are referred to as short FFTs, can be performed with the buffered data. The first short FFT can be processed. When results of the processing indicate the signal is radar, the radar can then be identified.

Abstract: This disclosure is directed to wireless communication systems having a receiver capable of detecting chirping radar pulses. The systems and methods include processing an input signal to obtain a spectral analysis that identifies which frequency exhibits maximum signal magnitude at a given time and determines a rate of change that frequency. By determining that the rate of change is within parameters established by the pulse width range and the chirping bandwidth range, the signal can be identified as a chirping radar pulse. By comparing the rate of change to known characteristics, the signal can be identified as a chirping radar pulse. Suitable characteristics include parameters for the rate of change established by the pulse width range and the chirping bandwidth range and linearity of the rate of change.

Abstract: This disclosure provides systems, methods, and apparatuses for wireless communication. An example apparatus selects a resource unit (RU) for a physical (PHY) layer convergence protocol (PLCP) protocol data unit (PPDU). The selected RU includes a set of contiguous tones spanning a bandwidth. The apparatus maps the set of contiguous tones to a set of non-contiguous tones distributed across the frequency spectrum, and transmits the PPDU over the set of non-contiguous tones. Another example apparatus selects an RU of a group of RUs that collectively span a frequency spectrum, and formats a PPDU based on a first frequency bandwidth wider than the selected RU's bandwidth. The apparatus parses the contiguous tones of the selected RU to a set of non-contiguous tones spanning a unique segment of a second frequency bandwidth wider than the first frequency bandwidth, and schedules a transmission of the PPDU over the set of non-contiguous tones.
