  • 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: 20230403754
    Abstract: A user equipment (UE) is configured to establish network connections for long-term evolution (LTE) and new radio (NR) radio access technologies (RATs) in non-standalone (NSA) E-UTRA-NR dual connectivity (ENDC) operation. The UE includes a multi-antenna array for data and signaling transmissions and receptions over the LTE and NR connections. The UE determines a most efficient antenna of the multi-antenna array for an operating frequency band of the LTE and NR connections, wherein the most efficient antenna is determined based on at least one performance factor for the UE when using the antenna compared to other antennas of the multi-antenna array, evaluates one or more factors for determining whether the LTE RAT or the NR RAT is to use the most efficient antenna and transmits uplink data on the most efficient antenna via either the LTE RAT or the NR RAT based on the evaluated factors.

  • 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: 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.
