    Abstract: Optimizations for simultaneous voice and data experiences in cellular networks include methods of handling voice call fallback, e.g.: (1) on VoNR when an IMS PDU session is established but an Internet PDU session is not yet established; (2) on VoNR when IMS and Internet PDU sessions are established in different network slices; (3) on VoNR when an IMS PDU session is established but a rejection is received for an Internet PDU session; (4) on an LTE network after an EPSFB procedure when an IMS bearer is not present; (5) on an LTE network after an EPSFB procedure when an IMS bearer is present but an Internet bearer is not; (6) on VoNR when a network does not support simultaneous voice and data; (7) when a VoNR-capable UE is camped to SA on a VPLMN; and (8) when a non-VoNR-capable UE is camped to SA on a network that supports VoNR.

    Abstract: Techniques and wireless devices to perform adaptive measurement object prioritization in a cellular communication scenario. A wireless link is established by the wireless device with a serving cell of a cellular base station. Adaptive measurement object prioritization is implemented responsive to determining that a trigger condition has occurred. A configuration message is received from the base station, where the configuration indicates a plurality of measurement objects including both Long Term Evolution (LTE) and New Radio (NR) measurement objects. A first measurement object of the plurality of measurement objects is selected to prioritize for measurement. The first measurement object is measured during a first measurement gap prior to measuring one or more second measurement objects of the plurality of measurement objects, and a measurement report is provided to the serving cell specifying a measurement result of the first measurement object.
