Abstract: 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.

Abstract: Methods, systems, and devices for wireless communications are described that provide for user equipment (UE) camping in a virtual cell. A UE may camp in a virtual cell and may be in an idle mode or an inactive mode in the virtual cell. The UE may transition out of the idle or inactive mode and switch from camping in the virtual cell to connecting to a physical cell encompassed by the virtual cell through reselection, redirection, and handover procedures. The virtual cell may include a central unit and multiple distributed units, which may be configured in various physical implementations. Additionally, the virtual cell may be limited to broadcast only or selective unicast signaling.

Abstract: 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.

Abstract: Certain aspects of the present disclosure generally relate to methods and apparatus for performing minimization of drive test (MDT) operations. For example, certain aspects provide a method for wireless communication. The method generally includes receiving, at a radio access network (RAN), a measurement configuration to start a trace of a user-equipment (UE), determining a transition of the UE to an inactive state, and sending one or more messages to coordinate the trace of the UE or indicate that the trace has failed in response to the determination.

Abstract: Certain aspects of the present disclosure provide techniques for multiple radio access technology (RAT) carrier aggregation (CA), such as Long Term Evolution (LTE)-New Radio (NR) CA. The method, in one example, comprises generating a first resource coordination information (RCI) comprising one or more resource coordination bitmaps indicating one or more shortened transmission time intervals (sTTIs) of a TTI assigned to the first RAT for communication, wherein the TTI comprises a plurality of sTTIs. The method further comprises transmitting a message including the first RCI to a second base station that uses a second RAT. The method further comprises receiving an acknowledgement of the message from the second base station, the acknowledgment including a second RCI comprising one or more modified resource coordination bitmaps indicating the one or more sTTIs assigned to the first RAT for communication and one or more additional sTTIs of the TTI assigned to the second RAT.

Abstract: Methods, systems, and devices for wireless communications are described. An access and mobility management function (AMF) associated with a first radio access network (RAN) may identify a user equipment (UE) connected to a source base station of the first RAN. The AMF may receive a handover message comprising a voice call continuity handover trigger message indicating a handover of the UE to a target base station associated with a second RAN. In some examples, the AMF may transmit a bypass handover message to a second network device associated with a third RAN based a on the received handover message. In some cases, the bypass handover message may include the voice call continuity handover trigger message. In some examples, the second network device is a mobility management entity (MME) associated with an Evolved Universal Terrestrial Radio Access Network (E-UTRAN).
