1. A method performed by a wireless device for radio access technology (RAT) dependent device-based positioning in a wireless communication network, the method comprising:
receiving, from a network node, assistance data that assists the wireless device with RAT-dependent device-based positioning, wherein the assistance data is based on device-specific information that includes a level of a subscription of the wireless device, wherein, based on the level of the subscription of the wireless device being higher than a threshold level, the assistance data includes cell-specific information for one or more cells, clusters of cells, or zones of clusters, wherein, for each of the one or more cells, clusters of cells, or zones of clusters, the cell-specific information includes a real-time difference between the cell, cluster of cells, or zone of clusters and each of one or more others of the one or more cells, clusters of cells, or zones of clusters; and
performing the RAT-dependent device-based positioning based on assistance from the assistance data, wherein performing the RAT-dependent device-based positioning comprises the wireless device calculating its own position based on the assistance data.
