Abstract: Aspects of the disclosure relate to a controllable reflective surface (e.g., reconfigurable intelligent surfaces (RIS)) that reflects in multiple directions simultaneously. The controllable reflective surface may include an array of reflecting elements, each reflecting element comprising a radiating component and a phase-shifting component. The array of reflecting elements may be configured to receive control signal sets, where each control signal set configures the array of reflecting elements into a reflecting configuration having a plurality of subsets of the reflecting elements. Here, each subset of the plurality of subsets is configured to reflect radio frequency (RF) signals in a respective direction different from other ones of the first plurality of subsets. The reflecting configuration may define, for example, a block-wise configuration, and interlaced configuration, or a hybrid configuration of the plurality of subsets. Other aspects, embodiments, and features are also claimed and described.

Abstract: Disclosed are techniques for determining a line-of-sight (LOS) path between a transmitter and a wireless device. In an aspect, a wireless device receives a first reference signal on a first frequency band at a first time, receives a second reference signal on a second frequency band at a second time, compares the first time to the second time, and determines, at least based on the comparison of the first time to the second time, which of the first reference signal and/or the second reference signal followed the LOS path between the transmitter and the wireless device.

Abstract: A multi-band antenna having a tuned antenna element is disclosed. The multi-band antenna may simultaneously transmit a first radio frequency (RF) and a second RF signal. The antenna may include a driven antenna element to radiate the first RF signal and a parasitic element to radiate the second RF signal. The parasitic element may be coupled to a ground plane through a tuning circuit. The tuning circuit may modify a resonant wavelength of the parasitic element according to the second RF signal.

Abstract: Techniques for providing multiple antennas in a wireless device using a compact configuration to achieve good isolation and broad bandwidth. In an aspect, first and second monopole elements that may be separately driven are provided on opposite sides of a grounding strip conductively coupled to a common grounding structure. By capacitively coupling the first and second monopole elements to the common grounding structure, the effective resonator size of each monopole antenna is increased, thus achieving better performance for the antenna structure. Illustrative patterns for the common grounding structure and other antenna elements are further disclosed.

Abstract: A first wireless communication device, such as a base station, may include separate transmit and receive antenna arrays. The separation between the transmit and receive antenna arrays may cause a direction of a transmit beam formed at the transmit antenna array to be different from a direction of a receive beam formed at the receive antenna array. The transmit and receive beams may be formed for communication with a second wireless communication device, such as a user equipment (UE). The described aspects enable the first wireless communication device to monitor a difference between a first direction of the transmit beam and a second direction of the receive beam. The first wireless communication device may transmit an indication of a beam correspondence failure to the second wireless communication device when the difference between the first and second directions is greater than or equal to a beam correspondence threshold.

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: Aspects of the disclosure relate to an apparatus (e.g., a user equipment (UE)) configured to operate in a full-duplex mode. The apparatus may include at least one transmit chain configured to operate within a first frequency band and at least one receive chain configured to operate within a second frequency band. The apparatus may receive coordination information that is configured to mitigate the self-interference between the at least one transmit chain of the apparatus and the at least one receive chain of the apparatus. In some examples, the received coordination information includes at least one of subcarrier spacing coordination information, beam coordination information, or slot format index coordination information. In some examples, the apparatus may transmit a first signal while receiving a second signal based on at least the subcarrier spacing coordination information, the beam coordination information, or the slot format index coordination information to mitigate self-interference.

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.
