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: Apparatuses, systems, and methods for a wireless device to perform methods for de-registration of the wireless device from a first access type over a second access type. Methods also include procedures for maintaining state machines associated with both access types as well as procedures to determine a connection for re-transmitting a de-registration request and to avoid collisions between procedures associated with the first and second access types. Further, methods include an information element configured to indicate which access type has been de-registered.

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 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 substantially concurrent communications with a next generation network node and a legacy network node. The wireless device may be configured to establish a first wireless link with a first cell according to a RAT, where the first cell operates in a first system bandwidth and establish a second wireless link with a second cell according to a RAT, where the second cell operates in a second system bandwidth. Further, the wireless device may be configured to perform uplink activity for both the first RAT and the second RAT by TDM uplink data for the first RAT and uplink data for the second RAT if uplink activity is scheduled according to both the first RAT and the second RAT.

Abstract: Methods, systems and apparatus for a user equipment to mitigate interference in a wireless charging state. The user equipment may determine when the user equipment enters a wireless charging state and, when the user equipment enters the wireless charging state, activate an interference mitigation. The user equipment may further determine when the UE exits the wireless charging state and, when the user equipment exits the wireless charging state, deactivate the interference mitigation.
