A communication system may include a base station (BS), user equipment (UE), and a set of reconfigurable intelligent surfaces (RIS's). The RIS's, the UE, and the BS may communicate using a control RAT and a data RAT. The BS may transmit downlink (DL) signals to the UE device via reflection off a DL RIS. The UE device may transmit uplink (UL) signals to the BS via reflection off a UL RIS. This may optimize wireless performance in situations where reflecting the UL and DL signals off the same RIS would limit performance under the current data RAT channel conditions. The BS and the UE device may use channel measurements of the control RAT at the RIS's to select the UL RIS and the DL RIS. This may significantly reduce overhead required to identify the UL and DL RIS's relative to scenarios where exhaustive beam training is used.

Communication via uplink and downlink reflective devices

A wireless communication system may use forward-forward learning to for end-to-end learning. A transmitter may pass a positive dataset and a negative dataset through each of its layers for model training. Each layer may correspond to a goodness function. The transmitter may send the positive dataset to a receiver. The receiver may generate a second positive dataset and a second negative dataset based on the positive dataset sent from the receiver. The receiver may train each of its layers using the second positive dataset and the second negative dataset.

Forward-forward learning based wireless communications systems

Techniques for beam width control, and devices and components including apparatus, systems, and methods for beam width control are described herein.

Beam width control

Protocol for beam width control

An electronic device may include a set of antenna panels (APs) that transmit and receive signals within a set of signal beams. A proximity sensor such as a radar sensor may gather sensor data indicative of the position an external object. The device may select an AP and a beam that maximize wireless performance in communicating with a base station while also complying with the radio-frequency exposure (RFE). The device may select the AP and the beam based on the sensor data, per-panel and per-beam projected RFE values, antenna port RFE characteristics, per-panel and per-beam transmit power limits, per-beam transmit power backoffs, an RFE lookup table, regulatory RFE limits, and antenna performance metrics. The device may transmit an RFE report to the base station that identifies some or all of this information for use in updating scheduling for the device.

Radio-frequency exposure beam management and selection in communications systems

A wireless network may include a base station and user equipment (UE). The UE may transmit uplink (UL) signals to the base station using a dynamically adjustable maximum UL duty cycle. When the UE identifies that a user is in proximity to the UE, the UE may transmit an indicator to the base station. The indicator may identify that a radio-frequency exposure (RFE) event has occurred and/or a suggested maximum UL duty cycle that would allow the UE to satisfy limits on RFE. The base station may limit a UL grant to the UE so that the UE performs subsequent communications using the suggested maximum UL duty cycle or a different maximum UL duty cycle. Coordinating adjustment of UL duty cycle in this way may allow the UE to meet limits on RFE without requiring the UE to perform maximum transmit power level reductions.

Systems and methods for controlling radio-frequency exposure

User equipment in close proximity may transfer data and control information. For example, the user equipment may exchange data or data sets between each other. Each user equipment can receive and transmit data using radio access technologies. A group of user equipments may include active user equipment and passive user equipment. Active user equipment connects with one or more base stations and transfers data on a wireless communication network via the base station. The active user equipment may communicate with other active user equipment and passive user equipment. Passive user equipment may not connect to any base station and/or the wireless communication network and may communicate with other passive user equipment and active user equipment (e.g., via a sidelink, peer-to-peer, or device-to-device channel).

Formation of user equipment groups

An electronic device may include radios that transmit signals using antennas. Control circuitry may assign radio-frequency exposure (RFE) budgets to the radios. The control circuitry may classify and predict attributes of application data for transmission over the radios, may generate a per-radio data prediction based on the classified attributes, and may generate the RFE budgets based on the classified attributes. Each radio may transmit application data based on its data prediction and according to its RFE budget. A dynamic portion of the RFE budget may be reserved for control signaling. RFE planning in this way may ensure that the device optimally utilizes its RFE budget, increasing overall RFE during some time periods so sufficient transmit power is available, and ensuring that RFE is distributed across the radios depending on the amount and criticality of the data to be transmitted by each radio.

Control signaling reservation for radio-frequency exposure management

Systems and methods for user equipment group management and control

User equipment may transmit and receive wireless signals to and from various communication networks. Furthermore, user equipment may indicate usage capabilities to the various wireless communication networks to enable the user equipment to transmit and/or receive wireless signals to and from at least two different communication networks. In particular, the user equipment may indicate usage capabilities of supporting both Frequency Range 2 (FR2) wireless signals of a fifth generation (5G) network and 7-24 gigahertz (GHz) wireless signals of a sixth generation (6G) network in an intermediate frequency range of the user equipment. The communication network(s) may then configure and/or schedule the user equipment based on the usage capabilities to enable the user equipment to simultaneously or non-simultaneously communicate using both the FR2 wireless signals and the 7-24 GHz wireless signals while preventing interference in the intermediate frequency range of the user equipment.

Systems and methods for network coexistence

Techniques discussed herein can facilitate enhancements to measurement for a User Equipment (UE) in Radio Resource Control (RRC) Connected mode for configuration of Carrier Aggregation (CA) and/or Dual Connectivity (DC). One example embodiment comprises a UE device comprising a processor configured to perform operations comprising: transmitting a UE Assistance Information message comprising a measurement request; receiving a first RRCReconfiguration message comprising a measConfig information element (IE); performing one or more measurements on each of on one or more frequencies based at least on the RRC measConfig IE, wherein the one or more frequencies comprise at least one non-serving frequency associated with a neighboring cell; transmitting a MeasurementReport message that indicates the one or more measurements for at least one of the one or more frequencies; and receiving a second RRCReconfiguration message that configures the UE with the at least one of the one or more frequencies.

Measurement enhancement in radio resource control (RRC) connected for user equipment (UE)

Various aspects of the present disclosure generally relate to media systems. In some aspects, a media device may monitor, using a radio frequency (RF) sensor, an environment of the media device; determine, from a received RF signal obtained by the RF sensor, a user attribute of a user within the environment; and control an audio system, associated with the media device, to direct an audio beam toward or away from the user. Numerous other aspects are provided.

Radio frequency sensing for control of a media system

Some aspects of this disclosure relate to apparatuses and methods for communicating in a first radio access technology (RAT) and a second RAT. A user equipment (UE) can receive, from a first base station using the first RAT, first configuration information for the UE to communicate with a second base station via the second RAT; and receive, from the first base station using the first RAT, a downlink message to enable a communication link between the UE and the second base station via the second RAT. The downlink message includes second configuration information for the UE to communicate with the second base station via the second RAT. The UE can establish the communication link between the UE and the second base station using the second RAT based on a link configuration obtained from the first configuration information and the second configuration information.

Communications using multiple radio access technologies (RAT) for a multi-mode user equipment (UE)

Cooperative communication for user equipment groups

An electronic device may include a first set of radios subject to a specific absorption rate (SAR) limit and a second set of radios subject to a maximum permissible exposure (MPE) limit over an averaging period. Control circuitry may dynamically adjust radio-frequency (RF) exposure metric budgets provided to the radios over the averaging period, based on feedback reports from the radios identifying the amount of SAR and MPE consumed by the radios during different subperiods of the averaging period. The control circuitry may distribute and adjust SAR budgets and MPE budgets across the radios based on the feedback reports, distribution policies, radio statuses, transmit activity factors, and/or usage ratios associated with the radios. This may provide efficient utilization of the total available SAR and MPE budget, thereby leading to increased uplink coverage and throughput relative to scenarios where the SAR and MPE budgets remain static.
