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: 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).

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: An electronic device may include a radio that generates a first maximum power based on a radio-frequency exposure (RFE) budget. The radio may transmit signals subject to the first maximum power during a subperiod of an averaging period and may generate an instantaneous RFE metric value based on an antenna coefficient and the conducted transmit power of the antenna during the subperiod. The radio may generate a consumed RFE value by averaging the instantaneous RFE metric value with previous instantaneous RFE values from the averaging period, may generate a remaining budget based on the consumed RFE value, may generate a second maximum transmit power based on the remaining budget, and may transmit signals during a subsequent subperiod subject to the second maximum power. Time-averaging the RFE metric may serve to optimize performance of the radio relative to scenarios where the radio performs time-averaging of conducted TX power.

Abstract: 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.

Abstract: User equipment may include a transmitter and a receiver coupled to an antenna to enable the user equipment to transmit and receive user data with a base station of the wireless network. However, the user equipment may perform power-consuming searches to determine a base station for connection. Furthermore, the connection may be affected by blockages and transitions during mobility scenarios. As such, it may be beneficial for the user equipment to implement mobility procedures. For example, the user equipment may form links with multiple base stations of a cell cluster for transitioning. In another example, the wireless network may generate a map with locations of base stations and beam characteristics for the user equipment to determine coverage areas and decrease a number of transitions. Still in another example, the user equipment may receive blockage information to predict a blockage and implement mobility procedures to maintain wireless service during a blockage.
