Abstract: Apparatus, methods, and computer-readable media for enhanced inter-frequency detection between misaligned base stations are disclosed herein. A user equipment (UE) may determine that a neighbor cell associated with a first frequency is misaligned with a serving cell associated with a second frequency different than the first frequency based on first measurements of the neighbor cell within a first measurement gap window having a first length. The UE may detect a location of a synchronization signal block (SSB) associated with the neighbor cell within a second measurement gap window having a second length greater than the first length. The UE may determine an alignment offset between the location of the SSB and the first measurement gap window. The UE may obtain second measurements of the neighbor cell within a third measurement gap window that includes the location of the SSB based on the alignment offset and parameters of the SSB.

Abstract: In a dual network link scenario, a wireless network may provide a user equipment (UE) with a measurement configuration indicating multiple inter-frequency measurement objects during an off duration of a discontinuous reception (DRX) cycle configured on a first network link. The UE may assign the inter-frequency measurement objects to a second network link if the second network link has an always-on configuration. Alternatively, if the second network link has a DRX configuration, the UE may perform some inter-frequency measurement activities on the first network link and assign some inter-frequency measurement objects to unoccupied gap occasions in the off duration for the DRX cycle configured on the second network link. In this way, the UE may save power by spending more time in a low power state, and mobility performance for the UE may be improved by increasing the efficiency and reliability of inter-frequency measurement activities.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station according to a first radio access technology (RAT) in a first frequency range. The UE may perform measurements on a set of candidate cells of a second RAT or a second frequency range based on a determination for the UE to operate according to the second RAT or the second frequency range. The UE may perform a mobility procedure to establish a connection with a first cell of the set of candidate cells based on a determination that a first value of a first measurement parameter for the first cell satisfies a first threshold, and further based on a comparison of a different, second value of a second measurement parameter for the first cell to a second threshold.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station associated with a first radio access technology (RAT), a neighbor cell list including entries for at least a first set of neighbor cells and a second set of neighbor cells, the first set of neighbor cells and the second set of neighbor cells associated with a second RAT. The UE may determine that the first set of neighbor cells is associated with a first network operator and that the second set of neighbor cells is associated with a second network operator. The UE may measure at least one neighbor cell of the neighbor cell list based at least in part on prioritization of the first set of neighbor cells relative to the second set of neighbor cells. Numerous other aspects are described.

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.

A device of a packed column, a cartridge, a tube, a well plate, a membrane, or a planar thin-layer chromatography plate includes a solid support and a hybrid ligand coupled to the solid support. A second method forms an immobilized hybrid ligand.

Abstract: A method of wireless communication determines whether the timing of a non-serving RAT is known. When the timing is known and it is time to report on the non-serving RAT, the UE clears enough consecutive time slots to verify the identity of the base station in the non-serving RAT. During the cleared time slots the identity of the base station is verified. When the timing is unknown and it is time to report on the non-serving RAT, a UE clears enough consecutive time slots to measure the timing of the non-serving RAT and to verify the identity of a base station in the non-serving RAT. During the cleared time slots, the timing is acquired and the identity of the base station is verified.
