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

The present disclosure provides procedures for early synchronization based on Idle mode measurements to enable fast connection establishment and resumption on transition to a Connected mode. When transitioning () to a Connected state, the UE selects one or more cells/frequencies for which in addition to the target cell configured/activated by the network to initiate early synchronization () prior to transition to the Connected state. When the UE receives () a message from the network requiring the UE to synchronize with a target cell in a target frequency, the UE determines () if the message from the network indicates that the UE shall configure or add a target cell, that is not the PCell, for which the UE has synchronized and, if so, uses the synchronization information to initiate () a random access procedure towards the target cell configured/activated by the network.

Neighbor cell synchronization upon state transition

A method performed by a first network node in a radio access network is provided. The method includes determining to initiate a procedure with a first set of at least one neighboring network node. The method further includes, responsive to the determining, sending to the first set of at least one neighboring network node a first message including timing accuracy information for at least one synchronization source of the first network node on at least one of a per cell basis, a per network node basis, or a per neighboring network node for a cell served by the first network node.

Communicating timing accuracy information for synchronization source of network node and related apparatuses

A method of a wireless communication device of acquiring position information. The method comprises transmitting, to a service-providing node, a request for service, receiving, from the service-providing node, a request for information indicating the position of the wireless communication device, receiving, from a network node, information indicating a position of the wireless communication device, the information having been provided with an indication of authenticity by the network node, and transmitting, to the service-providing node, the position information having been provided with an indication of authenticity.
