Abstract: Generally, the described techniques provide for efficiently transmitting uplink signals to a base station using shared antennas associated with different power classes. A first device may be in communications with a base station using local antennas and may identify a second device having auxiliary antennas available for transmitting uplink signals to the base station. The local and auxiliary antennas may be associated with different power classes, and the first device may transmit a message to a base station indicating that the first device is capable of transmitting using antennas associated with different power classes. The first device may then receive configurations from a base station of different transmit powers to transmit on the antennas associated with the different power classes, and the first device may transmit uplink signals to the base station in accordance with the different transmit power configurations.

Abstract: During an uplink TDD slot, an UL UE transmits an UL signal that occupies a slot frequency range. Similarly, during a DL TDD slot, a DL UE receives a DL signal that occupies the slot frequency range. But during an SBFD slot, a UL UE transmits a UL signal that occupies only a first sub-band of the slot frequency range. Similarly, a DL UE receives a DL signal during an SBFD slot that occupies only a second sub-band of the slot frequency range. The second sub-band is distinct from the first sub-band. The DL UE may thus mitigate UE-to-UE interference during an SBFD slot by filtering the DL signal to substantially block the second sub-band from being received at the DL UE.

Abstract: A low profile conformal high gain multi-beam aircraft antenna includes antenna elements supported by a ground plane to create the low profile conformal high gain multi-beam aircraft antenna. Some of the antenna elements include a feeding waveguide flared in at least one of an h-plane and a v-plane. The antenna elements cooperate to create a gain pattern near a plane of the antenna.

Abstract: An antenna structure is disclosed that includes a first antenna extending from a substrate, a second antenna formed on the substrate, and first and second parasitic elements formed on the substrate. The first antenna provides an omni-directional radiation pattern in the azimuth plane for vertically polarized signals, and the second antenna provides an omni-directional radiation pattern in the azimuth plane for horizontally polarized signals. The parasitic elements absorb and re-radiate electromagnetic waves radiated from the second antenna.

Abstract: Methods, systems, and devices for wireless communications are described for self-interference or cross-link interference measurements at a user equipment (UE). A UE may receive configuration information from a base station that indicates one or more slot format index (SFI) values that are compatible for cross-link interference or self-interference measurements. Based on the configured SFI(s), the UE may measure interference in multiple symbols, which may be used to estimate an amount of cross-link interference or self-interference, and the UE may transmit a measurement report to the base station. The base station, based on the measurement report, may identify one or more compatible SFIs, beam pairs, or combinations thereof, for subsequent communications with one or more UEs. The interference measurements may identify cross-link interference at the UE that results from transmissions of a different UE, or may identify self-interference of concurrent communications of multiple channels at a same UE.

Abstract: A base station is disclosed that includes two separated antenna arrays. In a TDD mode of operation, both arrays are used for either transmit or receive. In a sub-band full-duplex mode of operation, one array is used to transmit downlink symbols while the remaining array is used to receive uplink symbols.

Abstract: Disclosed are techniques for determining a line-of-sight (LOS) path between a transmitter and a wireless device in a wireless communications network. In an aspect, a wireless device receives, from the transmitter, a first reference signal transmitted on a first antenna port and a second reference signal transmitted on a second antenna port, the first reference signal having a first polarization and the second reference signal having a second polarization with known difference (e.g., perpendicular) to the first polarization, compares multi-path channels estimated from reception of the first reference signal and the second reference signal to multi-path channels expected from the first reference signal and the second reference signal when transmitted along the LOS path between the transmitter and the wireless device, and determines which path (if any) of the multi-path channels corresponds to the LOS path between the transmitter and the wireless device.
