POSITIONING WITH SPLIT ANTENNAS PER CELL

摘要

In a split antenna system, a radio network node determines an association between a target wireless terminal and an antenna being used to communicate with the target wireless terminal. The radio network node provides an association information and a signal information of properties of a wireless signal used for communication between the antenna to a positioning node. The association information can include the identity of the antenna, which can be encoded in least significant bits of a position measurement included in the signal information. The positioning node determines a position of the target wireless terminal based on the association information and the signal information.
