A method of operating a wireless communication device () comprising a wireless interface () having a capability to use a first identity () and a second identity (), the method comprising: determining a timing offset between a first timing of first paging occasions (-) of a first network (-) associated with the first identity () and a second timing of second paging occasions (-) of a second network (-) associated with the second identity (); and based on the timing offset (-), transmitting at least one request control message () to at least one of the first network (-) or the second network (-), to request a timing coordination of paging from the first network (-) and paging from the second network (-).

Paging of multi-sim wireless communication devices

A method, performed by a network node, is disclosed for handling positioning of a User Equipment, wireless device. The network node obtains a first approximate position of the wireless device, based on a first positioning procedure for the wireless device in a first frequency allocation. The network node determines, based on the first approximate position of the wireless device, a set of resources to be used for a second positioning procedure in a second frequency allocation. The network node initiates the second positioning procedure in the second frequency allocation using the determined set of resources. The network node obtains an updated position of the wireless device based on the second positioning procedure.
