Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for enhancement of multi-SIM devices, such as UE 106. A network may increase paging retries for known MU-SIM devices, e.g., based on an indication of capabilities from a MU-SIM device. The indication may be via a NAS registration request, an RRC capability procedure, and/or an RRC UE assistance procedure. Additionally, a network may include an indication of a paging priority to the UE. The UE may then determine a response to the page based, at least in part, on the indicated priority. Further, the UE may indicate a tune-away to the network. The indication of the tune-away may include a cause and/or duration for the tune-away and may be provided at an RRC level or a network access stratum (NAS) level.

Abstract: A device and method for generating a user equipment (UE) capability information message. In a first embodiment, a UE receives a request for the radio access capabilities of the UE and a size limit indication for a message to be generated by the UE that includes the radio access capabilities. The UE generates the message that includes the radio access capabilities based on the size limit then transmits the message to the network. In a second embodiment, a UE receives a request for the radio access capabilities of the UE. The UE also receives a segment limit indication and a size limit indication for a message to be generated by the UE that includes the radio access capabilities. The UE generates the message where the message includes a plurality of segments based on the segment limit. Subsequently, the UE transmits the message to the network.

Abstract: Apparatuses, systems, and methods for a dual subscriber identity module (SIM) dual standby (DSDS) capable user equipment (UE) devices to perform data operations with a first SIM that is not capable of or preferred for packet switched (PS) services and a second SIM that is capable of or preferred for PS services. A timer may be initiated upon radio frequency (RF) chain handover from the first SIM to the second SIM, whereupon a first connection associated with the first SIM is maintained in an idle state while the timer is running. Upon expiration of the timer, the UE may determine whether to send a scheduling request to maintain or release the first connection. The timer may be utilized when a call is dropped over the first connection, to increase the likelihood of successfully receiving a callback. The timer may be shortened in duration to reduce reception of spam messaging.

Abstract: A user equipment device (UE) may receive a schedule for a listen before talk (LBT) procedure for a secondary component carrier on a first subscription associated with the UE that includes a radio frequency resource of the UE. The UE may determine a requirement to perform at least one operation on a second subscription associated with the UE that also includes the radio frequency resource. The UE may determine that performance of the at least one operation (at least partially) interferes (time overlaps) with performance of the LBT procedure. In response, the UE may initiate at least one scheduling operation at the UE to avoid interference between performance of the at least one operation on the second subscription and performance of the LBT procedure on the first subscription.

Abstract: Apparatuses, systems, and methods for a wireless device to perform methods to dual-registration in a fifth generation (5G) New Radio (NR) network, including notification procedure enhancements over cellular (e.g., 3GPP) and non-cellular (e.g., non-3GPP) access, dual-registration enhancements, and paging enhancements. Methods also include procedures for a network to determine an access type to notify a UE of pending data and for a wireless device and network to mitigate paging collisions.

Abstract: Embodiments described herein relate to managing access to 5G cellular baseband resources for 5G-capable wireless devices. A wireless device can monitor application workloads by analyzing communication network performance requirements for a given application in-use or launching for future use along with system-level indications of overall device usage, battery level, and mobility status to determine whether access to 5G cellular baseband resources is recommended for an application. A 5G cellular baseband resource recommendation is provided for an application indicating a level of bandwidth in current use or expected for future use as well as a confidence metric in the bandwidth level indication. The 5G cellular baseband resource recommendation is used with additional device criteria to determine whether access to one or more 5G radio frequency bands is allowed.

Abstract: Techniques disclosed herein relate to reducing RRC signalling messages. Techniques can be employed to reduce the number of Random Access Channel (RACH) attempts to obtain NotBroadcasted (e.g., On Demand System Information(s) (SIs)) by a UE in response to a paging message indicating SI modification. The UE may monitor the Physical Broadcast Channel (PBCH) for a given duration in attempt to decode the On Demand SI(s) without initiating a RACH procedure. If the UE fails to decode the On Demand SI(s) within the given duration, the UE may initiate a RACH procedure to obtain the On Demand SI(s).
