Abstract: A user equipment UE configured to initiate a first voice call with a first network associated with a first subscriber identity module SIM1 of the UE, receive a paging request from a second network indicating an incoming voice call associated with a second SIM2 of the UE, wherein the paging request is received while the first voice call is active, perform a radio resource control RRC connection setup with the second network and perform one of accepting the incoming voice call or rejecting the incoming voice call, provide an indication to the second network that dual connectivity DC carrier aggregation CA should be suspended such that the second network only configures the UE with a single component carrier CC on the SIM2 and exchanging SIP messages with the second network to retrieve a caller identification ID of the incoming call from the SIM2

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for support mobility in a wireless network for user equipments (UEs) with varying capabilities. A UE can receive a first system information from a serving base station, where the first system information includes a UE capability condition associated with a neighbor base station, and determine whether a UE capability meets the UE capability condition associated with the neighbor base station. When the UE capability condition is met, the UE can determine whether a first measurement of a first reference signal received from the serving base station and a second measurement of a second reference signal received from the neighbor base station satisfy a threshold condition. When the threshold condition is met, the UE can obtain a second system information from the neighbor base station, indicating the UE has performed handover to the neighbor base station.

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.

Abstract: An electronic device may include wireless circuitry with a radio that conveys wireless data with a wireless base station using antennas according to a communication schedule and that performs sensing using the antennas. The sensing may involve transmission of sensing signals and reception of reflected signals during sensing periods. Control circuitry may adjust timing of the sensing periods, based on network configuration information and the current sensing requirements of the device, to align with scheduled inactive times for the radio. In this way, the radio may perform radio-frequency sensing for use in adjusting wireless transmissions to satisfy radio-frequency exposure requirements without substantially disrupting wireless data communications.
