Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a node may receive a configuration associated with measuring an energy level of a first frequency channel of an unlicensed radio frequency band, wherein the configuration indicates a set of measurement occasions during which the energy level is to be measured on the first frequency channel; measure the energy level on the first frequency channel in a first measurement occasion, of the set of measurement occasions, according to the configuration, and operate in association with a second frequency channel of the unlicensed radio frequency band based at least in part on measuring the energy level on the first frequency channel, wherein the second frequency channel is paired with the first frequency channel for the unlicensed radio frequency band.

Abstract: A method and system are disclosed that allow for the control of transmission characteristics associated with an exchange of protocol data units (PDUs) between a first wireless device and a second wireless device. The first wireless device determines a number of transmission conditions that may include, for example, a maximum duration of time that the first wireless device can spend receiving or transmitting each PDU. The first wireless device embeds the transmission conditions into a frame, and transmits the frame to the second wireless device. The second wireless device may selectively modify a size of the PDUs in response to the maximum duration of time so that the first wireless device can receive each of the PDUs in less than the maximum duration of time.

Abstract: A user equipment (UE) includes a first communication component configured to use a first frequency band, such as ultra-wide band (UWB), and a second communication component configured to use an intermediate frequency (IF) band that overlaps with the UWB band, such as an IF millimeter wave (mmWave) band. The second communication component conducts an IF signal along an internal signal conduction line that may interfere with UWB processing. A processor of the UE is configured to detect an indication of such interference, and, in response to the indication of interference, control the second communication component to adjust a characteristic of the IF band signal to mitigate the interference, such as by reducing its signal strength. The amount by which the IF band signal strength is reduced may be controlled to achieve a desired tradeoff between various performance metrics, such as power consumption and quality of service.

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: This disclosure provides methods, devices and systems for improving wireless communications in power spectral density (PSD)-limited frequency bands. A wireless communication device, having a number (NTX) of transmit antennas, parses a physical layer (PHY) protocol data unit (PPDU) into a number (NSS) of spatial streams and modulates the NSS spatial streams on a number (M) of subcarriers. In some implementations, the wireless communication device may transmit the PPDU using a number (N) of the transmit antennas, where NSS≤N

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for determining one or more frequency channels for use in wireless communication. Some implementations more specifically relate to determining one or more frequency channels for unlicensed wireless communication in a frequency band also used for licensed wireless communication, such as a 6 GHz frequency band. In one aspect, a database system is configured to store information associated with existing wireless systems or links including the locations of such systems as well as characteristics of the wireless signals they transmit. In another aspect, a wireless communication device is configured to determine its location, transmit its location to a database system, and receive information from the database system usable to determine a frequency channel on which to communicate. In another aspect, a wireless communication device is configured to transmit a request including a unique identifier (ID) to a database system and to receive information from the database system usable to determine a non-blacklisted frequency channel on which to communicate.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless device may perform a listen-before-talk (LBT) procedure for a narrowband communication that provides time and frequency synchronization and/or scheduling information for an ultra-wideband (UWB) communication. The wireless device may transmit the narrowband communication in response to the LBT procedure being successful. The wireless device may transmit the UWB communication based at least in part on the time and frequency synchronization and/or scheduling information. Numerous other aspects are described.
