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: This disclosure provides methods and devices for realizing sensitivity gains for high-efficiency (HE) extended range (ER) dual carrier modulation (DCM) modes. A wireless communication device can determine one or more preamble symbols of a packet based on a mode of transmission of the packet, the one or more preamble symbols of the packet being associated with a receiver sensitivity limitation. The wireless communication device can apply a power boost of a to the one or more preamble symbols by a power boost value, the power boost value being based on the mode of transmission of the packet. The wireless communication device can determine whether the one or more preamble symbols with the applied power boost satisfy a spectral mask. The wireless communication device can transmit the packet when the one or more preamble symbols with the applied power boost satisfy the spectral mask.

Abstract: This disclosure provides methods, devices, and systems for selecting antenna power levels based on polarization diversity. For example, a wireless communication device can determine first and second transmission power levels for a first set of one or more antennas and a second set of one or more antennas, respectively, based on a polarization diversity setting for a wireless communication device that is based on a first orientation of the first set of antenna(s) being orthogonal to a second orientation of the second set of antenna(s). The wireless communication device can transmit, to a target device, first signals at the first transmission power levels using the first set of antenna(s) and second signals at the second transmission power levels using the second set of antenna(s). The first signals are cross-polarized from the second signals based on the first orientation being orthogonal to the second orientation.

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.
