Abstract: Methods, systems, and devices for wireless communications are described. A device may be configured to include an array of lenses along with multiple antenna arrays that each include a set of antenna elements. The antenna arrays may each support multiple beam directions, such as a respective beam direction for each lens of the array of lenses. If beams for multiple antenna arrays concurrently pass through the same lens, the lens may contribute to maintaining separation between the beams. Lenses may also contribute to the shaping of beams, and the use of multiple lenses may enhance a coverage area for beams transmitted or received by the antenna arrays.

Abstract: Multiple input multiple output (MIMO) communication systems and methods for chip to chip and intrachip communication are disclosed. In one aspect, MIMO techniques that have been applied to wireless communication systems are applied to interchip and intrachip communication systems. In particular, a transfer function is applied at the transmitter, and a reverse transfer function is applied at the receiver. The transfer function dynamically changes based on channel conditions to cancel or otherwise mitigate electromagnetic interference (EMI) and crosstalk conditions. In an exemplary aspect, a sum of power levels across the channels may have a maximum. To abide by such power level constraint, the transfer function may be optimized to reduce interference while remaining within the power level constraint.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless node (e.g., a vehicle mounted integrated access and backhaul (IAB) node) may aid in wireless communication between one or more wireless devices operating in a high-speed environment (e.g., on a high-speed train (HST)) and one or more network entities. The wireless node may transmit one or more reference signals associated with a Doppler estimation procedure to the one or more network entities. The network entities may use the one or more reference signals to generate a set of Doppler compensation parameters to use while communicating with the wireless node and the one or more wireless devices. In some examples, the wireless node may receive control information or data from the one or more wireless devices, aggregate the information, and transmit the aggregated information to the one or more network entities on behalf of the wireless devices.

Abstract: Aspects presented herein may enhance the navigation function of navigation/map applications or systems when GNSS signals are weak or sporadic. In one aspect, a UE monitors a position of the UE based on GNSS communication, where the position of the UE is monitored using at least one first map layer of a plurality of map layers associated with a map. The UE detects that the position of the UE corresponds to a predefined location when the GNSS communication is below a communication threshold. The UE switches to monitoring the position of the UE using at least one second map layer of the plurality of map layers upon detecting that the position of the UE corresponds to the predefined location, where the at least one second map layer is associated with the predefined location.

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: Methods, systems, and devices for wireless communications are described. In a wireless communications system. a user equipment (UE) may receive. from a base station, control signaling indicating a quasi co-location (QCL) configuration associated with multiple-input multiple output (MIMO) communications within a distance threshold from the base station. In some cases, the UE may receive. from the base station, an indication of a downlink transmission associated with the QCL configuration within the distance threshold. The UE may select a beam to receive the downlink transmission within the distance threshold based on the QCL configuration. In some cases. the UE may receive multiple repetitions of the downlink transmission using corresponding antenna combining weight configurations, and the UE may determine a beam weight configuration for the beam to receive the downlink transmission based on receiving the multiple repetitions of the downlink transmission.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may be configured to transmit, to a second wireless device, one or more orbital angular momentum (OAM) signals in accordance with a set of radial codeword sequences associated with a polynomial radial codeword configuration, where the one or more OAM signals are transmitted based on a first value of a polynomial term for the polynomial radial codeword configuration. The first wireless device may receive, from the second wireless device on the one or more OAM signals, a feedback message indicating a second value of the polynomial term. The first wireless device may then transmit, to the second wireless device, one or more additional OAM signals in accordance with the set of radial codeword sequences and based on the second value for the polynomial term.

Abstract: Methods, systems, and devices for wireless communication are described. Some wireless communications systems may support rotational alignment of a first antenna panel of a first device and a second antenna panel of a second device. The first and second devices may exchange signaling that indicates a panel rotation capability and a panel rotation procedure configuration based on the panel rotation capability. The second device may transmit a reference signal from a central antenna element of the second antenna panel based on the configuration. The first device may receive the reference signal via two antenna elements of the first antenna panel and may adjust an angular rotation of the first antenna panel based on the reference signal to modify a respective distance between each of the two antenna elements of the first antenna panel relative to the central antenna element of the second antenna panel.
