  • Patent number: 12089100
    Abstract: Aspects relate to techniques for expediting New Radio (NR) cell addition in non-standalone (NSA) mode. The UE may receive a conditional handover (CHO) command from a first anchor cell operating a first frequency range (e.g., a Long Term Evolution (LTE) frequency range) that enables the UE to subsequently select a different anchor cell to which to perform a handover. The UE may then receive a deconfiguration from the first anchor cell of a measurement object for secondary cell addition in a second frequency range (e.g., a NR frequency range). Based on the CHO command and the deconfiguration of the measurement object, the UE may then perform a handover to a second anchor cell in the first frequency range to facilitate addition of at least one secondary cell in the second frequency range.

  • Publication number: 20240187982
    Abstract: Methods, systems, and devices for wireless communication are described that provide for cell selection or reselection at a user equipment (UE) based on cell selection preference criteria of the UE. The UE may receive a set of cell selection criteria that provides a priority order for cell selection based on one or more cell features, cell types, or combinations thereof. The UE, based on one or more signal measurements of available cells and the cell selection criteria, may select one of the available cells for communications. The UE may also maintain a feature cell database in which a number of cells and an associated feature mask may be stored and used to identify cells having features or types associated with the cell selection criteria for use in cell prioritization. Cell selection criteria may be used for cell selection/reselection procedures, mobility procedures, or any combinations thereof.

  • Publication number: 20240080738
    Abstract: Techniques for recovering quickly from a radio link failure (RLF) by identifying potentially strong candidate cells, while avoiding the conventional delays from relying only on initial ACQ DB scans followed by band-scanning, are disclosed. In one aspect, a wireless apparatus such as a user equipment (UE) may identify a radio link failure (RLF) of an existing wireless connection. The UE may prioritize, during an RLF recovery procedure for restoring the connection, candidate cells using connection criteria from one or more measurement reports. The UE can thereupon restore the connection using a cell having a highest priority. In various configurations, the UE can use cells from A3, A4, A5, inter-RAT or periodic measurement reports to reestablish a stronger connection in a faster time.
