Abstract
Method and arrangement in a network node 302 for improving conditions for ground-based positioning of mobile terminals 310 in a wireless communication system. The method and arrangement concerns adaptation of an antenna arrangement 308 associated with the network node 302, so that a virtual positioning cell 306 is formed in a positioning radio resource, in which positioning reference signals are transmitted or received.
Claims14
A method in a network node for improving conditions for ground-based positioning of mobile terminals in a wireless communication system, comprising:
- generating a traffic cell for user data traffic using an antenna arrangement of the network node configured for said generating;
- adapting the configuration of the antenna arrangement, in a positioning radio resource, to form a virtual positioning cell, wherein the configuration of the antenna arrangement is adapted by switching between connecting one or more dedicated positioning antennas and connecting one or more traffic antennas, and
- transmitting or receiving reference signals used for positioning in said positioning radio resource, using the adapted antenna arrangement.
A network node adapted to improve conditions for ground-based positioning of mobile terminals in a wireless communication system, where said network node comprises:
- an antenna arrangement comprising at least one antenna configured to generate a traffic cell for user data traffic;
- an antenna arrangement control circuit configured to adapt the configuration of the antenna arrangement in a positioning radio resource, to form a virtual positioning cell, wherein the configuration of the antenna arrangement is adapted by switching between connecting one or more dedicated positioning antennas and connecting one or more traffic antennas;
- and
- at least one of a transmitting circuit configured to transmit, and a receiving circuit configured to receive, reference signals used for positioning in said positioning radio resource, using the adapted antenna arrangement.
