An example wireless device () in a dormant state improves its selection of a camping cell by accounting for multi-cell configurations. Among other things, a multi-cell configuration may improve throughput between a wireless communication network () and the wireless device (), based on the network () serving the wireless device () from two or more cells (). By camping on a cell () that belongs to a multi-cell configuration that is possible for the wireless device (), the wireless device () reduces the time and signaling needed to establish that multi-cell configuration, upon the wireless device () connecting to the network () via the camping cell. Accounting for multi-cell configurations may be done jointly, along with accounting for conventional priorities, such as conventionally-prioritized frequencies and Radio Access Technologies (RATs) and may be incorporated into the ranking of cells () based on per-cell radio-signal measurements.

Method and apparatus for cell selection in a wireless communication network

A first radio access network, RAN, node in a communication network can determine whether to provide dual connectivity to a user equipment, UE, in the communication network based on an UL quality. The first RAN node can receive data indicating characteristics of an uplink, UL, channel of one or more UL channels for a second RAN node in the communication network. The first RAN node can estimate an UL quality of the UL channel based on the data. The first RAN node can determine based on the UL quality, whether to provide dual connectivity to the UE in the communication network by adding the second RAN node as a secondary node serving the UE.
