摘要： Wireless communications systems and methods related to mobility with consideration for network slicing are provided. In one embodiment, a user equipment (UE) transmits in a first cell frequency of a network, a request for a network slice of the network that is not provided by the first cell frequency. The UE receives, in response to the request, an information for communicating in a second cell frequency of the network that provides the requested network slice. In one embodiment, a core network entity receives, from a network entity operating over a first cell frequency of a network, a request to provide a network slice of the network to a UE, the network slice not provided by the first cell frequency. The core network entity transmits, to the BS, information associated with a second cell frequency of the network providing the network slice.

摘要： Methods, systems, and devices for wireless communications are described. A UE may establish a wireless communication link with a base station in accordance with a radio access technology (RAT), and an internet connection with the base station. The UE may identify a lack of support by a network that includes the base station for a type of voice calls associated with the RAT. The UE may transmit a discovery query for a gateway to a core network, and the UE may establish a connection with the gateway via the internet connection. The UE may initiate a voice call via a call path from the UE to the core network, where the call path may include the wireless communications link with the base station in accordance with the RAT and also may include the internet connection with the gateway.

摘要： Certain aspects of the present disclosure relate to methods and apparatus for improving voice over new radio (VoNR)-to-voice over long term evolution (VoLTE). An example method generally includes communicating with and camping on a next generation node B (gNB) in a 5G new radio (NR) system; initiating a voice call with the gNB; receiving a 5G NR-to-long term evolution (LTE) handover command in response to initiating the voice call; performing a handover procedure in response to the handover command; detecting a failure in the handover procedure; and taking one or more actions in response to detecting the failure in the handover procedure.

摘要： This disclosure provides systems, methods, and apparatus for wireless communications that support fast user equipment (UE) handover between base stations. A UE may receive, from a source base station, a configuration for reference signal transmission at a set of uplink transmit power levels. The UE may transmit multiple uplink reference signal repetitions based on the configuration. The source base station may transmit a request message to a target base station to measure the multiple uplink reference signal repetitions. The target base station may select an uplink reference signal and measure a transmit power correction. The target base station may transmit an indication to the source base station of the selection and transmit power correction. The source base station may evaluate the indications and select the target base station. The source base station may forward to the indicated contents, and the UE may switch and synchronize with the target base station.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify that a radio resource control connection is to be established for evolved packet system fallback or inter radio access technology fallback from New Radio for a voice call. The UE may determine that an establishment cause received from a network access stratum (NAS) layer does not indicate high priority access. The UE may override the establishment cause such that the establishment cause indicates a mobile originated (MO) voice call based at least in part on determining that the establishment cause received from the NAS layer does not indicate high priority access. The UE may perform an access barring check of an MO voice call based at least in part on overriding the establishment cause such that the establishment cause indicates an MO voice call. Numerous other aspects are provided.

摘要： Aspects of the present disclosure provide techniques for routing internet protocol (IP) and non-IP packets in cellular vehicle-to-everything devices that can be transmitted over the air via cellular or side-link device-to-device (D2D) communication systems without the need for the applications (e.g., automotive applications) to modify its operations. Specifically, an application (automotive application or web browser) may use default Application Programming Interface (API) that is typically used for regular cellular communication without modifying its operations to differentiate between IP and non-IP packets. Instead, in accordance with present disclosure, logical data paths may be dynamically adjusted to map services associated with the packets with an appropriate media access control (MAC) flow such that the modem receiving the packet may process and route the packet to target end-destination.

摘要： Methods, systems, and devices for wireless communications are described that provide for a user equipment (UE) to report packet switched voice call capabilities to a base station. The UE may explicitly report voice call capabilities via one or more system-level parameters that are transmitted to the base station. The base station may operate in a first radio access network (RAN), such as a 5G or new radio (NR) RAN. In cases where the UE indicates a capability for packet switched voice calls via the first RAN, one or more voice calls may be established with the UE via the first RAN. In cases where the UE indicates that it is not capable of packet switched voice calls via the first RAN, the UE may fall back to a different RAN (e.g., a 4G or LTE RAN, a 3G RAN, or a 2G RAN) for voice calls.

摘要： A user equipment (UE) receives a circuit switched page from a first radio access technology (RAT) and a command instructing the UE to redirect to a second RAT. The command indicates a designated location area identity of the second RAT. The UE detects base stations of the second RAT and determines whether a strongest base station is in an area identified by the designated location area identity. The UE connects to the strongest base station based on the determining. When the designated location area identity is a permitted location area, the UE connects to the strongest base station when the location of the strongest base station is included in the permitted location area. When the designated location area identity is a prohibited location area, the UE connects to the strongest base station when the location of the strongest base station is not included in the prohibited location area.
