Abstract: A user equipment (UE) receives a SIB1 message from a base station. The SIB1 message lists first and second public land mobile network identifiers (PLMN IDs), the first PLMN ID having a corresponding tracking area code (TAC) and the second PLMN ID not having a TAC. The UE reports the first PLMN ID and TAC but not the second PLMN ID while performing PLMN selection. In another aspect, the UE unsuccessfully attempts to select or reselect to a shared cell of the base station with the second PLMN ID. In response to the failed attempt, the UE bars the shared cell as a candidate for cell selection/reselection, due to a missing TAC. When the UE attempts to select or reselect to the shared cell with the first PLMN ID, which may or may not have a TAC, the UE reevaluates the barring due to selection of the first PLMN ID.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform a scan, associated with a cell selection procedure, that prioritizes a first frequency that is identified in a frequency database over a second frequency that is not identified in the frequency database. The frequency database may identify one or more frequencies associated with cells that are determined to support a multi-radio access technology (RAT) dual connectivity or that have a neighboring cell that is determined to support a standalone mode of a RAT. The UE may acquire a cell on which to camp based at least in part on performing the scan. Numerous other aspects are provided.

Abstract: This disclosure provides systems, methods and apparatuses for establishing wireless connections with nonstandalone (NSA) -anchor Long Term Evolution (LTE) cells. In one aspect, a mobile device may perform a first frequency scan for one or more NSA-anchor LTE cells. The mobile device may determine whether a LTE base station is configured as an NSA-anchor LTE cell based on the first frequency scan. The mobile device may, in response to determining that the LTE base station is configured as the NSA-anchor LTE cell, camp on the LTE base station configured as the NSA-anchor LTE cell. Camping, and connecting to the NSA-anchor LTE cell may result in higher data throughput at the mobile device, and may improve overall user experience.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may be configured to communicate using a first subscription and communicate using a different second subscription. The user equipment may receive a closed subscriber group (CSG) whitelist for the different second subscription, which may comprise a closed subscriber group (CSG) identity. The user equipment may be configured to perform, via the different second subscription, a reselection to a closed subscriber group (CSG) member cell associated with the CSG identity using at least one of one or more signal measurements, which were obtained by performing at least one autonomous search function via the first subscription, or one or more portions of one or more system information messages, which were obtained by performing at least one autonomous search function via the first subscription.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first signal associated with a first radio access technology (RAT) and a second signal associated with a second RAT. The UE may determine that first signal measurements associated with the first signal satisfy a first condition and second signal measurements associated with the second signal satisfy a second condition. The UE may transmit, to a first base station associated with the first RAT, a measurement report that excludes the first signal measurements and the second signal measurements based at least in part on the first condition and the second condition being satisfied. Numerous other aspects are described.

IPC: H04W76/12

Abstract: Systems and method for smart measurement scheduling and reporting are disclosed. A user equipment (UE) being served by a cell of a first radio access technology (RAT) network may identify a target cell of another RAT network for rapid redirection based on a fingerprint database and the measurement report of the target cell. In aspects, the UE may trigger redirection to the target cell by reporting a measurement report associated with the target cell typ. The UE determines whether to stay in the current network or to switch over to another network based on traffic type, a scenario or condition, latency requirements, power savings, etc. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a UE in a connected state with a cell of a first radio access technology (RAT) type may trigger a UE initiated inter-RAT redirection procedure to a neighboring cell of a different, higher priority level, RAT type if the network does not configure the UE to perform connected measurements for candidate neighbor cells of the higher priority level RAT type. A UE may receive an indication of candidate neighbor cells of a higher priority level RAT type. The UE may perform UE initiated measurements on the indicated candidate neighbor cells of the higher priority level RAT type. The UE may trigger an inter-RAT redirection procedure to one of the neighbor cells of the higher priority level RAT if the UE finds a suitable cell based on the UE initiated measurements.
