摘要: 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.

摘要: 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.

摘要: 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.

摘要: 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.

摘要: 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.

摘要: 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.

摘要: A high gain multi-beam aircraft blade antenna of an air-to-ground antenna systems includes multiple columnar matrix antenna elements housed within a blade.
