Abstract: 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.

Abstract: 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.

Abstract: Techniques discussed herein facilitate Base Station (BS) enhancements to measurement by a RRC Connected mode User Equipment (UE) for configuration of Carrier Aggregation (CA) and/or Dual Connectivity (DC). One example embodiment comprises a BS device comprising a processor configured to perform operations comprising: receiving a UE Assistance Information message comprising a measurement request; transmitting a first RRCReconfiguration message comprising a measConfig IE; receiving a MeasurementReport message from a UE that indicates one or more measurements on one or more sets of frequencies, wherein the one or more sets of frequencies comprise a set of serving frequencies for one of a serving cell or the neighboring cell and a set of non-serving frequencies for the UE, wherein the set of non-serving frequencies are associated with the neighboring cell; and transmitting a second RRCReconfiguration message that configures the UE with at least one set of the one or more sets of frequencies.

Abstract: 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.

Abstract: Performing autonomous measurements at a user equipment (UE) may include encoding a radio resource control (RRC) connection request for transmission to a first base station having a first base station type. An RRC connection setup communication received from the first base station may be decoded. Measurements associated with a set of candidate carriers of a second base station type may be autonomously performed while in an RRC connected state. Autonomously performing the measurements may including deriving the set of candidate carriers to be measured. Results from the performed measurements may be stored.
