Abstract: Apparatuses, systems, and methods for performing network slice quota management. A network slice quota management function may store capacity information for one or more network slices. The network slice quota management function may receive a request for an indication of whether a network slice has additional capacity. The network slice quota management function may provide an indication of whether the network slice has additional capacity in response to the request. The capacity information may relate to the capacity of the network slice with respect to the number of wireless devices registered for the network slice, or to the capacity of the network slice with respect to the number of packet sessions established with the network slice, or both, among various possibilities.

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 stablish 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: Techniques are disclosed relating to handover of WLAN voice calls to one or more cellular networks. In some embodiments, a device is configured to perform voice communications over one or more wireless local area networks, communicate with a first network using a first cellular radio access technology (RAT), and communicate with a second network using a second cellular RAT. The device may store, based on communications via the first network, information indicating that the first network does not support voice communications for the apparatus. The device may handover a voice call from a wireless local network directly to the second cellular RAT, based on the stored information and without handover of the voice call to the first cellular RAT, based on call conditions on the wireless local area network.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE), manufacturer server, and/or cellular network to perform radio capability signaling. A new type of UE radio capability identifier is provided which may allow a network to distinguish between similar UEs that have or have not implemented a capability update. In order to perform a forced capability update, a manufacturer may issue information about the update to a cellular network (and receive acknowledgement of the information) prior to pushing the update to UEs. In response to an unforced capability update, a cellular network may maintain multiple UE radio capability identifiers for similar UEs which have or have not implemented the update. A UE radio capability identifier may be adjusted dynamically in response to temporary changes in the UE's capability.

Abstract: This disclosure relates to providing coexistence features for cellular communication in unlicensed spectrum. A wireless device may communicate with a cellular base station in accordance with an original communication configuration. The wireless device may determine that a communication activity is occurring at the wireless device that has a duration longer than a duration threshold. The wireless device may provide an indication to the cellular base station to modify the communication configuration with respect to operation in an unlicensed frequency band based at least in part on determining that a communication activity is occurring at the wireless device that has a duration longer than the duration threshold. The wireless device may communicate with the cellular base station in accordance with a modified communication configuration.

Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for EPS fallback when initiating a voice call while camped on a 5G cell. The UE may camp on a 5G network by performing an IMS registration procedure/IMS SIP invite procedure with an IMS. The UE may initiate a voice call and determine that the voice call cannot be established over the 5G NR network. In response, the UE may perform a TAU procedure or an attachment procedure with a cell of a 4G network. The IMS may be transferred to the 4G network during TAU/attachment procedure. The UE may, in response to determining that it is barred from the 4G network, transition back to the 5G network and transmit, to the 5G NR network, a SIP cancel request to allow a context associated with the UE to be cleared from the IMS.

Abstract: This disclosure relates to techniques for a wireless device to re-establish a packet data network connection. The wireless device may establish a packet data network connection via a cellular link with a cellular base station. Information identifying a bearer associated with the packet data network connection may be stored by the wireless device. The wireless device may determine whether the bearer associated with the packet data network connection is active. The packet data network connection may be released by the wireless device and the wireless device may attempt to re-establish the packet data network connection if the bearer associated with the packet data network connection is determined to not be active.

Abstract: A device and method for a user equipment (UE) to implement power savings mechanisms when operating within a significant location. The UE identifies that the UE is at a significant location. The significant location is a location relative to a currently camped cell of a network. At a first time and at the significant location, the UE performs a type of operation related to the network connection. The UE stores information corresponding to the performance of the type of operation at the first time in a profile associated with the significant location. At a second time and at the significant location, the UE performs the type of operation related to the network connection. The performance of the type of operation at the second time is modified based on the information stored in the profile associated with the significant location.
