Abstract: A first transmission power level based on a radio frequency exposure limit and a second transmission power level based on the first transmission power level and a probability of detection of a body by a body proximity sensor are determined, where it is ensured that an average usage of the first and second transmission power levels over time does not exceed the transmission power limit, determined based on radio frequency exposure limits. A transmission power gain is determined based on a difference between the first and second transmission power level based on the probability of detection, and a false alarm rate of the body by the body proximity sensor. The transmission power gain may be used as a performance indicator to select from multiple first and second transmission power gains. First and second transmission power gains corresponding to the selected transmission power gain may be stored and applied during transmission.

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.

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: Systems and methods for radio frequency exposure control using dynamic absorption limits based on non-colocated antenna cluster separation distance are discussed herein. A user equipment (UE) performs first data transmission using a first antenna cluster during a first portion of an RF exposure duration that uses up to a maximum RF exposure limit per RF exposure duration. Further, the UE performs second data transmission using a second antenna cluster during a second portion of the first RF exposure duration that (also) uses up to the maximum RF exposure limit per RF exposure duration. A separation distance between the first antenna cluster and the second antenna cluster meets a minimum threshold for the use of the maximum RF exposure limit per RF exposure duration at each of the first antenna cluster and the second antenna cluster during the first RF exposure duration.

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: A user equipment (UE) configured to receive an uplink (UL) grant comprising a UL grant size, determine a current UL buffer size, compare the current UL buffer size to the UL grant size and determining an amount of padding to fill the UL grant and determine whether to transmit on the UL grant based on the amount of padding to fill the UL grant.

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: 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.
