Apparatus and methods are provided for a user equipment (UE) to communicate with a new radio (NR) wireless network in a standalone deployment. The UE camps on a first cell and determines that a first bandwidth (BW) of the first cell is greater than or equal to a threshold BW value. In response, when the UE is not configured for bandwidth part switching (BWPS), the UE determines whether a second cell is available that is intraband with and has a same priority as the first cell and that has a second BW that is less than the threshold BW value. When the second cell is not available, the UE searches for a next lower priority cell that has a third BW that is less than the threshold BW value.

Apparatus and methods to mitigate no bandwidth part switching in 5G standalone deployments

This disclosure relates to techniques for a wireless device to determine a radio access technology availability indicator to present. A wireless device may establish a wireless link with a cellular network via a cell that operates according to a first radio access technology. The wireless device may determine if access to the cellular network is also available via a cell that operates according to a second radio access technology, by configuration by the serving cell or from another standalone cell. The wireless device may select a radio access technology availability indicator to present based at least in part on determining if access to the cellular network is also available via a cell that operates according to the second radio access technology.

Determining a radio access technology availability indicator to present

Apparatuses, systems, and methods for a wireless device to perform detection and mitigation of data stalls. The mitigation may occur during and/or at initiation of a data connection. The wireless device may establish a data connection(s) with a network over a Wi-Fi or cellular interface and monitor the data connection(s) for a data stall condition(s)/hint(s). The wireless device may perform a remedial action(s) responsive to detection of a data stall condition(s)/hint(s), including initiating a service recovery of the cellular interface, initiating a radio access technology (RAT) upgrade procedure, and/or initiating a handover procedure to a neighbor cell.

Cellular enhancements for application mobility

This disclosure relates to methods and devices for a user equipment device (UE) to perform band measurements and provide a pruned measurement report to a base station. A first connection is established between the UE and a base station, and a configuration message is received from the base station. The configuration message identifies a plurality of bands for which the UE is to provide measurement reporting. The UE determines whether a band combination of the plurality of bands has an aggregate bandwidth that is greater than the aggregate bandwidth of the first connection and whether a signal quality metric of the determined band combination is greater than a predetermined threshold. Responsive to these determinations, the UE performs band measurements on the bands of the band combination and transmits a pruned measurement report to the base station.
