Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to perform intra-UE co-existence between non-stand-alone (NSA) and stand-alone (SA) mode. The UE may be configured to connect to a first radio access network (RAN) operating according to a first radio access technology (RAT) via a first radio and connect to a second RAN operating according to a second RAT via a second radio. The UE may provide, to the first RAN, configuration information during a radio resource control (RRC) connection procedure. The configuration information may indicate a dual connectivity status of the UE. The dual connectivity status may include indication disabling (enabling) dual connectivity for the UE, working frequencies associated with the second RAN, and/or configurations associated with the second RAN. The UE may receive, from the first RAN, a dual connectivity configuration that may be based on the dual connectivity status of the UE and operate accordingly.

Abstract: This disclosure relates to systems, apparatuses, and methods for coordinating communication and avoiding and/or mitigating collisions for multi-subscriber identity module devices in a wireless communication system. A wireless device may coordinate communication associated with different subscriber identity modules and/or may mitigate collisions between communications associated with different subscriber identity modules. A network may provide information to improve coordination and/or mitigate collisions. A network may adjust paging schedules and/or provision of alert messages to improve coordination.

Abstract: A device, system and method for a user equipment (UE) to opportunistically utilize the wireless capabilities of a paired device. The UE is configured to establish a first cellular network connection based on a first subscription, a second cellular network connection based on a second subscription and a connection to a further UE based on a short-range communication protocol. The UE identifies a predetermined condition and transmits an indication to the further UE based on the predetermined condition. The further UE establishes a further cellular network connection in response to the indication and the further cellular network connection is based on one of the first subscription or the second subscription. The UE then declares no service for one of the first cellular network connection or the second cellular network connection based on the further cellular network connection.

Abstract: A user equipment (UE) device may make measurements of network-configured frequencies in an idle mode or an inactive mode, and report the measurements to the network during (or after) a connection establishment or a connection resume process. The initiation of measurements may be delayed until a connection is imminent or until an upper layer request. A result timer may be used to ensure that reported measurements are not too old to be of use. A configuration timer may be used to selectively report inter-frequency/RAT cell measurements. The configuration timer may also be used repeatedly in conjunction with intervening backoff periods. A base station of the network may use the measurements to make informed decisions on when and how to configure carrier aggregation or dual connectivity for the UE device.

Abstract: An accessory device may establish a short range link to a companion device, and the accessory device may use the companion device as a proxy to conduct a data session over a cellular network. Based on a latency requirement associated with the data session and/or a signal strength of the short range link, the accessory device may dynamically determine to transition its cellular radio from a powered-off mode to a low power mode.

Abstract: Apparatuses, systems, and methods for a wireless device to perform methods for improvements of display of signal bars on a user interface of a wireless device. The wireless device may be configured to perform methods for determining a number of signal bars to display on the user interface based, at least in part, on a reference frequency. The reference frequency may be indicated and/or provided by a network.

Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for network assisted side-link resource configuration for unicast and/or multi-cast/groupcast communications in V2X networks. A UE may, after establishing an RRC connection with a base station, transmit, to the base station, V2X connection information. The V2X connection information may include a V2X identifier associated with the UE and a V2X identifier associated with a target UE. The UE may receive, from the base station, a side-link configuration for data transmission with the target UE. The side-link configuration may include a resource allocation defined in time and frequency (e.g., a transmit/receive pool). The UE may communicate with the target UE using the resource allocation included in the side-link configuration.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for performing unicast sidelink access stratum level connection maintenance. A first wireless device and a second wireless device may establish a unicast sidelink wireless connection. One or both of the first wireless device and the second wireless device may perform access stratum level connection maintenance on the unicast sidelink wireless connection. This may include performing any or all of radio link monitoring, radio resource management, or physical layer based link quality detection. The access stratum and the non-access stratum of each device may also communicate with each other regarding either or both of link quality or link status of the unicast sidelink wireless connection.

Abstract: A device, system, and method detect an activity and utilize a mitigation scheme. The method is performed at a device that is configured to establish a network connection to a network, the network including a plurality of areas, each area being defined based on a grouping of a plurality of neighboring cells, the device being associated with one of the areas at a select time. The method includes determining between an activity status and a non-activity status associated with the device. When the activity status is determined, the method includes determining an area update rate indicating a number of changes to the associated area over a period of time. When the area update rate exceeds a predetermined update rate threshold, the method includes selecting a mitigation scheme configured to reduce an amount of power used by the device.
