Abstract: This disclosure provides methods, components, devices and systems for intra-band enhanced multilink single-radio (eMLSR) communication. Some aspects more specifically relate to independently contending, using a single radio, for access on first and second links associated with first and second primary subchannels of a channel. A packet may then be transmitted, using the single radio, over a one of the first link or the second link on which contention is won.

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: 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.
