Abstract
The disclosure relates to technology for iterative localization and channel estimation in a communication system. A radio network node detects user location information from user equipment in a geographic region, where the geographic region includes a location cluster having multiple location levels. A location signature profile is formed for each level based on the location signature of a corresponding location level in the cluster, and a filter is generated for each level based on the location signature. Upon application of the filter that matches the location level of the location user information, the channel is estimated and the user location information is updated based on the channel estimation. The process is repeated until the user location information converges with a preselected convergence value.
