The technology described herein is directed towards a multiband unit cell that is part of a reflective surface that can reflect different specific frequencies of impinging electromagnetic waves. The unit cells can have different phase profiles to facilitate beam steering and/or beam splitting functionality, independently for each specific frequency. The multiband unit cell can be a dual-band unit cell based on a straightforward unit-cell design, e.g., using diagonally arranged ring resonators as sub-cells of a supercell. Alternative design variations are also described to accommodate multi-frequency (greater than two frequency) applications. In one example implementation, the metasurface is constructed as a low-profile dual-band reflective surface with beam-steering and/or beam-splitting capabilities, e.g., utilizing only a single unit cell metal layer above a substrate. This enables precise control and manipulation of an antenna's radiation pattern, providing enhanced coverage for both frequency bands while keeping the fabrication / manufacturing costs relatively low.

The technology described herein is directed towards a design and implementation of a unit cell for a reconfigurable intelligent surface / reflectarray by incorporating reconfigurability within a phase-delay element of the unit cell. Reconfigurability is directly incorporated into the unit cell via a variable length phase delay line element and PCM-based (e.g., mmWave) phase shifter that determines the unit cell's phase shift by changing the length of the phase delay line element. One implementation is directed to a monolithic integration of the element using chalcogenide materials as switch elements with pulsed actuation to switch among different available lengths that determine the length of the phase delay line element, resulting in a significant reduction in power consumption, area saving, and digital reconfigurability.

HYBRID ACTIVE-PASSIVE INTELLIGENT SURFACES FOR RADAR-BASED TARGET DETECTION
The technology described herein is directed towards a hybrid active-passive intelligent reflective surface (IRS) with configurable reflective elements to improve radar-based target detection. The elements of the IRS are configured via optimization, which determines which elements are active and which are passive, and optimizes the amplification coefficients based on an impinging signal from a radar system. Optimization increases the signal-to-noise ratio, thereby improving the radar system's ability to accurately detect objects. The optimized surface with only some elements active improves the energy efficiency, as does turning on the active elements only when assistance is needed by the radar system. Further, based on a probability of detection, the paths between the IRS and the radar system, and the IRS and a target can be controllably modified to obtain three-way communication between a moving target, an intelligent reflective surface, and the radar system, which can reduce the detection time.

If a violation of a remaining latency budget criterion has occurred, the user equipment may transmit a delay status report to the node. If the violation of the remaining latency budget criterion corresponds to an occurrence count that violates a remaining latency budget violation count criterion, the user equipment may adjust a remaining latency budget criterion to result in an adjusted remaining latency budget criterion, which may be used for generation and transmission of future delay status reports corresponding to packets stored in the buffer in the future. A remaining latency budget criterion may be adjusted based on a change in buffered traffic volume.
A reconfigurable intelligent surface is disclosed. The reconfigurable intelligent surface includes a moveable metallic ground plane and piezoelectric actuators that are connected to the moveable metallic ground plane.

The technology described herein is directed towards a capacitor with a modified design (relative to standard capacitors), in which a first conductor is coupled to a second conductor via a distributed array of conducting interconnects through a dielectric that separates the conductors. The array of interconnects facilitates electrical surface current flow between the first conductor and the second conductor, and determines the self-resonant frequency of the capacitor. The array (or enlarged area) of conducting interconnects, not present in standard capacitors, results in capacitors with larger self-resonant frequency, e.g., having a substantially stable capacitance over a range of high radio frequencies, including millimeter wave frequencies. This further provides an improved quality factor. The improvements resulting from the technology described herein facilitate more optimal surface current density. The modified capacitor provides benefits in various circuits, e.g., in an impedance or a millimeter wave frequency phase shifter for antenna elements.
The technology described herein is directed towards phase-change material-based (e.g., chalcogenide) radio frequency components that can be used in unit cells of a reconfigurable intelligent surface. A tunable device for reconfigurable operation is described, in which the phase shift of each unit-cell of reconfigurable intelligent surface is varied by rotationally controlling the conductive state of the phase-change material. The rotational angle can be selectively controlled by heating elements that change portions of the unit cell's lower-resistance states relative to its higher resistance states, resulting in a phase change of a unit cell with respect to redirecting an electromagnetic wave. By arranging the heating elements below the material, and actuating each one as appropriate to change otherwise-latched resistive or conductive states within the overall unit cell surface, an analog-like device operation is achieved to provide more granular phase shift control of the cells of a reconfigurable intelligent surface.

The user equipment may determine a coverage level based on the discovery signal and may transmit the coverage level and other coverage level information in a discovery signal coverage level report to a terrestrial radio node. The terrestrial node may receive coverage level information from another terrestrial node.

A terrestrial network node facilitating delivery of traffic with respect to a user equipment may determine to offload a portion of the traffic for delivery via the non-terrestrial network node. The terrestrial node may request the zone timing advance value, from a core network or from the non-terrestrial node, and may transmit a path switch request message comprising the zone timing advance value to the user equipment. The path switch request message may indicate traffic flows for which traffic is to be offloaded to the non-terrestrial node and may comprise indication of uplink resources corresponding to the non-terrestrial node to be usable by the user equipment to transmit the offloaded uplink traffic to the non-terrestrial node.

The terrestrial node may receive from the user equipment measured parameter values indicative of performance with respect to the non-terrestrial node that may satisfy a quality-of-service criterion corresponding to traffic currently being delivered by the terrestrial node. The terrestrial node, based on the measured parameter values, may determine that the quality-of-service criterion may be satisfied by delivery of the traffic via the non-terrestrial node, and the terrestrial node may schedule non-terrestrial resources corresponding to the non-terrestrial node. The terrestrial node may indicate to the user equipment the scheduled non-terrestrial resources. The non-terrestrial node may deliver traffic with respect to the user equipment according to the scheduled non-terrestrial resources.

An extended reality processing unit and one or more extended reality appliances may share a joint access code. The processing unit may transmit the access code and identifiers corresponding to the processing unit and the appliances to a radio access network node. The node may configure the processing unit and the appliances with respective control channel search space resources and respective scrambling codes corresponding thereto. The node may receive traffic directed to one of the appliances. If transmission of control channel information corresponding to the traffic would violate a latency criterion corresponding thereto, the node may puncture resources, configured for use by the processing unit, occurring during a joint search space occasion, to transmit the control channel information to the appliance. The node may determine a control information format that fits in remnant portions of the punctured joint search space occasion to deliver control information to the processing unit.
A radio network node may receive from a core network a beam pattern configuration and a progressive paging configuration comprising one or more paging subpattern indications. The node may calculate beams of the subpatterns based on information in the beam pattern configuration. The node may transmit a paging message according to indicated subpatterns according to an order in the progressive paging configuration. The progressive paging configuration may comprise one or more wait periods corresponding to the one or more subpattern indications. The node may wait during a wait period associated with a subpattern after transmitting the paging message according to the subpattern. If a response is not received, the node may transmit the paging message according to a next-in-order subpattern. If a response to the paging message transmitted during a subpattern is received by the node, paging may be stopped and a connection with the user equipment may be established.
A radio access network node may receive, from a core network, traffic information corresponding to an extended reality traffic flow associated with an extended reality processing unit or an end extended reality appliance. The node may transmit to the processing unit an uplink resource grant configuration indicating a sharable uplink resource usable to transmit uplink traffic to the node. The processing unit may receive uplink traffic from the appliance and may relay the uplink traffic to the node. The processing unit may determine that continued relaying of the uplink traffic may violate a criterion and may schedule sharable uplink resource(s), indicated in the uplink resource grant configuration, for use by the appliance in transmitting the uplink traffic directly to the node. The processing unit may transmit an uplink resource sharing report to the node to facilitate the node avoiding blind decoding the uplink traffic received according to the scheduled resource(s).
The technology described herein is directed towards informing user equipment of which physical downlink control channel (PDCCH) locations in a slot symbol are allocated for (PDCCH) information. With the user equipment having this allocation information, a base station (e.g., gNodeB) scheduler can schedule unused PDCCH resource element group(s) to a UE for physical downlink shared channel (PDSCH) decoding. Further, because the allocation pattern is known to a UE, the UE need not blindly scan and decode all potential resource element groups in a slot, instead only decoding the PDCCH data in the allocated pattern to find the UE-specific information, and thereby proceed with PDSCH decoding. A defined identifier at a predefined symbol location informs the user equipment when the PDCCH allocation information is present. If not present, the UE blindly decodes all the resource element groups to find the UE-specific information to decode PDSCH data, as is currently done.

The quality-of-service criterion may be indicated by a user equipment in an indication that may accompany the packet corresponding to the target flow, which may be an uplink flow. The user equipment may receive, from the node, a packet of the target flow via a shareable semi-persistent downlink scheduling occasion resource without waiting for a grant of the resource from the node.

A remote user equipment device may receive traffic payload from a source radio access network node, with which the remote user equipment has an established communication session, via a relay user equipment device of a sidelink path. The relay device may receive a path switch request, which may be triggered by degraded communication channel conditions between the remote device and the source node or the relay device. The path switch request may indicate a target node with which the remote device is to establish a communication session. Responsive to the switch request, the relay device may transmit to the source node a pending sidelink traffic indication indicative of traffic payload packets undelivered by the relay device to the remote device. The source node may transmit information indicative of the undelivered packets to the target node to facilitate the target node transmitting the undelivered packets to the remote device.
A radio access network node delivering a traffic flow via multicast broadcast service to multiple idle user equipment may determine one of the user equipment as a primary user equipment and the other user equipment as secondary user equipment.

The secondary user equipment may respond to a request for quality-of-experience information with a quality-of-experience metric availability indication or with actual quality-of-experience metric information. An availability indication may be used to reduce the size of a response to the request and also to reduce the size of a quality-of-experience report generated by the primary user equipment and transmitted thereby to the node. The quality-of-experience report may be transmitted by the primary user equipment to the node so that the idle secondary user equipment need not connect to the node to transmit quality-of-experience information.

The described technology is generally directed towards dynamically adapting the parameter data of an intercell interference avoidance feedback and decision window (e.g., sizing and frequency) to obtain interference-related data from a UE. The interference-related data analyzed from a returned window is used to recommend a decision to a ran node as to which radio resources should be avoided when scheduling UE-related communications to avoid intercell interference. A controller (e.g., RIC) dynamically attempts to optimize the frequency and periodicity of the intercell interference avoidance feedback and decision windows to be transmitted, based on measurements and KPIs from the RAN node, e.g., UE traffic pattern data and QoS requirements, as well as performance capability data of the node. The node can accept the window parameter data or reject the request for reprocessing by the controller.

RADIO UNIT TIME ALIGNMENT AND DELAY CHARACTERIZATION
Radio unit equipment that facilitates radio unit time alignment and delay characterization includes a buffer that stores input data received via a signal ingress point of the radio unit equipment, resulting in buffered data. The radio unit equipment also includes clock generation logic that provides a synchronized frame number (SFN) pulse to the buffer. The buffer releases the buffered data at a time corresponding to the SFN pulse and modified by a timing adjustment parameter, resulting in the buffered data proceeding from the buffer to a signal egress point of the radio unit equipment. Additionally, the buffer determines the timing adjustment parameter based on a defined signal propagation delay between the buffer and the signal egress point of the radio unit equipment.
Architectures and techniques are described relating to implementing a serving hub within a network architecture such as an open radio access network (O-RAN). The serving hub can, inter alia, abstract a MLOps layer, serve models, and expose models for reuse.
