Abstract: In an aspect, a wireless device is configured to transmit a physical layer protocol data unit on one or more channels, wherein the physical layer protocol data unit includes a first portion and a second portion. The first portion includes a signal length field indicating a duration of a transmission of the physical layer protocol data unit. The second portion includes a plurality of Wi-Fi sensing fields. The wireless device is configured to receive a reflected signal and a leakage signal associated with the physical layer protocol data unit. The reflected signal includes the physical layer protocol data unit reflected off of a target object. The leakage signal is associated with the physical layer protocol data unit.

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: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for wireless range extension for communication in a wireless local area network (WLAN). In some aspects, a first WLAN device and a second WLAN device may exchange one or more management frames advertising support for a non-orthogonal frequency-division multiplexing (non-OFDM) data rate for communications via one or more non-2.4 GHz bands. In some aspects, the non-OFDM data rate may be a data rate of a plurality of data rates associated with an IEEE 802.11b standard, and the one or more non-2.4 GHz bands may include one or more of a 3.5 GHz band, a 5 GHz band, a 6 GHz band, a 45 GHz band, and a 60 GHz band. The first and second WLAN devices may select the non-OFDM data rate and at least one of the non-2.4 GHz bands for exchange data communications.

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: A method, an apparatus, and a computer-readable medium for wireless communication are provided. An apparatus is configured to communicate over a primary channel via a first set of antennas and over the primary via a second set of antennas. The second set of antennas is switched from the primary channel to a secondary channel when the communication over the primary channel is idle. A channel availability checks (CACs) is performed on the secondary channel when the primary channel is idle to determine whether radar signals are detected on the secondary channel.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. For example, a wireless communication device (WCD), may include multiple component chips configurable to work together as a partitioned chip having a capability to communicate using a quantity of spatial streams that exceeds a capacity of any one of the multiple component chips when operated independently. Some aspects more specifically relate to component chips having frequency domain components that support a first quantity of spatial streams in a frequency domain and having time domain components that support a second quantity of spatial streams in a time domain. In some examples, the first quantity of spatial streams may correspond to a quantity of spatial streams that are transmitted or received by multiple component chips, and the second quantity of spatial streams may correspond to a quantity of spatial streams that are transmitted or received by a single component chip.
