  • Publication number: 20240138008
    Abstract: 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.

  • Publication number: 20230412203
    Abstract: Embodiments herein provide various apparatuses and techniques to for enhanced handling of receiver desensitization, “desense,” in electronic devices that is caused by an operation of the device. In an embodiment, sensitivity of a receiver affected by desense may be determined based on receiver sensitivity without desense and a desense offset value. Desense mitigation measures may be applied based on the strength of the signal received by the receiver being less than the receiver sensitivity affected by desense. The desense mitigation measures may include deactivating the device operation that causes desense, enabling the device operation that causes desense only during certain times, and enabling antenna diversity. In some embodiments, various power and signal-to-noise ratio thresholds may be used for conditional application of different desense mitigation measures.

  • Publication number: 20230413194
    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.

  • Publication number: 20230370107
    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.

  • Publication number: 20230354124
    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.

  • Publication number: 20230247452
    Abstract: Systems and methods are provided for a user equipment (UE) connected to a network using FR1 and configured for mmWave beam measurement to communicate using FR2. The UE receives, from a base station, measurement configuration information including an indication of measurement opportunities. The UE determines that a current data traffic type is associated with mmWave communication. In response to the current data traffic type being associated with the mmWave communication, the UE performs an FR2 cell addition measurement decision. The FR2 cell addition measurement decision may be based on one or more of signal quality feedback, sensor input, UE motion state, and geographic (geo) location information associated with FR2 cell information. Based on the FR2 cell addition measurement decision, the UE suppresses or selects a next measurement opportunity of the measurement opportunities for measuring one or more mmWave signals.
