Abstract
The present disclosure relates to systems and methods for determining the location of a wireless device in a shared cell deployment/system. In some embodiments, a method of operation of one or more network nodes comprises obtaining separate samples of at least a portion of one or more uplink transmissions received by at least a subset of a plurality of Receive/Transmit (R/T) points in a shared cell from a wireless device. The separate samples comprise, for each R/T point of the at least a subset of the plurality of R/T points in the shared cell, a sample of at least a portion of an uplink transmission received by the R/T point from the wireless device. The method further comprises performing multilateration based on range estimates for ranges between the wireless device and the at least a subset of the plurality of R/T points determined from the separate samples.
