Abstract: Techniques discussed herein can reduce RRC signaling messages, and various aspects can employ one or more of these sets of techniques. A first set of techniques can be employed to reduce RACH (Random Access Channel) requests from a RRC Idle State SIM (Subscriber Identity Module) of a UE in DSDS (Dual SIM Dual Standby) mode. A second set of techniques can be employed to reduce the number of RACH attempts to obtain NotBroadcasted (e.g., On Demand) SI(s) (System Information(s)) by a UE in response to a page message indicating SI modification.

Abstract: This disclosure relates to performing implicit radio resource control state transitions in a cellular communication system. A wireless device may establish a radio resource control (RRC) connection with a cellular base station. A data inactivity timer length and a target RRC state for implicit RRC transitions may be determined. A data inactivity timer having the determined data inactivity timer length may be initiated. It may be determined that the data inactivity timer has expired. The wireless device may transition to the target RRC state based at least in part on determining that the data inactivity timer has expired.

Abstract: A UE in an RRC inactive state may determine an operational state mismatch between an actual RRC operational state for the UE and a stored RRC operational state for the UE maintained at a network node. To determine the mismatch, while the UE is in the RRC inactive state, the UE may monitor at least one of paging messages, serving cell power levels, or neighbor cell power levels. When an operational state mismatch is detected, the UE may initiate a state correction procedure rather than an RRC resume procedure.

Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to prioritize cells that support EN-DC over similar cells not supporting EN-DC. The UE may be configured to perform one or more measurement scans associated with cell selection and/or cell re-selection and may determine whether at least two LTE cells meet a selection criteria based on RSRP and/or SNR measurements. The UE may be configured to, in response to determining that at least two LTE cells meet the selection criteria, prioritize a first LTE cell of the at least two LTE cells over a second LTE cell of the at least two LTE cells based, at least in part, on support EN-DC. The first LTE cell may indicate support of EN-DC, e.g., via a ULI IE included in a SIB2 broadcast by the first LTE cell. The UE may be configured to select the first LTE cell for camping.

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 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.

Abstract: A network controller, a user equipment (UE) device, and associated methods for adaptively prioritizing simultaneous unicast and multicast communications based on traffic classes. The UE may determine whether each of a unicast communication and a multicast communication are associated with a foreground application or a background application. The UE may further determine whether each of the unicast communication and the multicast communication are high priority or low priority. The UE may then buffer one of the unicast or multicast communications based on the whether it is associated with a foreground or background application, whether it is high or low priority, and whether it is a unicast or multicast communication.

Abstract: A device sets an activity mode for a cellular connection. A method to set the activity mode is performed at a device located with a user that is configured to establish a network connection to a network. The method includes determining a status of the user, the status indicating an activity state or a non-activity state of the user. The method includes, when the status indicates the activity state, activating an activity mode on the device that restricts select types of mobile originating data traffic.

Abstract: Techniques are described herein for network slice availability based de-prioritization. An example, method includes receiving user equipment (UE) routing selection policy (URSP) information. The method further includes starting an application associated with a network slice while registered with a standalone (SA) network. The method further includes evaluating routing selection descriptor information in the URSP information to determine an availability of the network slice of the SA network. The method further includes determining whether to de-prioritize the SA network based on a determination of availability of the network slice as indicated by the routing selection descriptor information.
