Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication transmitter may monitor a clear channel assessment (CCA) for a primary bandwidth associated with the transmitter. The wireless communication transmitter may determine whether an interferer is located within the primary bandwidth based at least in part on tracking packet drops, within the primary bandwidth, that are based at least in part on the CCA. The wireless communication transmitter may monitor one or more additional CCAs for one or more secondary bandwidths associated with the transmitter. The wireless communication transmitter may determine whether an interferer is located within at least one bandwidth, of the one or more secondary bandwidths, based at least in part on tracking packet transmissions, within the one or more secondary bandwidths, that are based at least in part on the one or more additional CCAs. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a wireless station (STA), which may be an example of a virtual reality (VR) device, may receive downlink data or video frames from an access point (AP) for a display at the wireless STA. In some aspects, the wireless STA may detect a motion change of the wireless STA based on employing a motion change detection mechanism and, if the wireless STA detects a motion change, may transmit an indication of the motion change detection to the AP via a feedback message, such as a block acknowledgement (BA) feedback message. The wireless STA, based on detecting the motion change, may additionally transmit a set of inertial measurements of the wireless STA to the AP. The wireless STA may transmit the inertial measurements to the AP via the feedback message or a separate uplink message.

Abstract: This disclosure provides methods, devices and systems for obtaining and providing channel feedback. In some implementations, a beamformee provides channel feedback to a beamformer that enables the beamformer to construct and independently precode two or more different sets of spatial streams for transmission to the beamformee. The independent precoding of the different sets of spatial streams ensures that the decodings of the different sets of spatial streams may be decoupled from one another at the beamformee. To provide the channel feedback, the beamformee partitions a channel estimate into two or more sub-estimates prior to performing a channel decomposition. In some implementations, the beamformee determines null-space-based projections of the sub-estimates before performing the channel decomposition.

Abstract: A yogurt maker device comprises an outer shell to house a yogurt vessel that receives milk and a culture container that receives yogurt culture. A processor within the outer shell controls a heating element to boil milk within the yogurt vessel using a temperature sensor as feedback and for maintaining a predefined boiling temperature for a predefined period of boiling time and a stirring device to continuously stir boiling milk within the yogurt vessel while boiling and also while cooling to a cooling predefined temperature until fermentation temperature is reached. The processor also controls a culture container base holding the culture container and having a motor to automatically pour the yogurt culture when the fermentation temperature is reached. Finally, a cooling mechanism automatically provides cooling to contents of the yogurt vessel once fermentation is complete.

Abstract: A method and apparatus are disclosed for a wireless communication device capable of scanning for radar signals while detecting and/or receiving a wireless communication signal. The wireless communication device may include a plurality of local oscillator synthesizers to allow distinct frequency bands to be used for wireless communication signals and radar detection. In some embodiments, the wireless communication device may include a radar detection physical layer (PHY) circuit to detect the presence of radar signals within a received RF signal. The radar detection PHY may have limited functionality suitable primarily for radar signal analysis and not suitable for processing (decoding) communication signals.
