Abstract: An example wireless device (12) 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 (10) and the wireless device (12), based on the network (10) serving the wireless device (12) from two or more cells (24). By camping on a cell (24) that belongs to a multi-cell configuration that is possible for the wireless device (12), the wireless device (12) reduces the time and signaling needed to establish that multi-cell configuration, upon the wireless device (12) connecting to the network (10) 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 (24) based on per-cell radio-signal measurements.
