Abstract
Embodiments of the present disclosure provide method and apparatus for positioning. The method may comprise receiving a first radio signal of a terminal device located in the area from a line of sight (LOS) path between the antenna array and the terminal device; receiving a second radio signal of the terminal device located in the area from at least one path reflected by the reflector; determining respective angles of arrival of the LOS path and the at least one path reflected by the reflector; and determining a location of the terminal device by using triangulation based on the respective angles of arrival.
Claims20
A method at a network device, wherein the network device comprises an antenna device including an antenna array with a radiation pattern including a main lobe, a back lobe and one or more side lobes and a reflector configured to reflect a part of energy of the back lobe to an area of at least one of the one or more side lobes, the method comprising:
- receiving a first radio signal of a terminal device located in the area from a line of sight (LOS) path between the antenna array and the terminal device;
- receiving a second radio signal of the terminal device located in the area from at least one path reflected by the reflector;
- determining respective angles of arrival of the LOS path and the at least one path reflected by the reflector;
- and
- determining a location of the terminal device by using triangulation based on the respective angles of arrival.
An apparatus at a network device, wherein the network device comprises antenna device including an antenna array with a radiation pattern including a main lobe, a back lobe and one or more side lobes and a reflector configured to reflect a part of energy of the back lobe to an area of at least one of the one or more side lobes, the apparatus comprising:
- a processor;
- a memory coupled to the processor, said memory containing instructions executable by said processor, whereby said apparatus is operative to:
- receive a first radio signal of a terminal device located in the area from a line of sight (LOS) path between the antenna array and the terminal device;
- receive a second radio signal of the terminal device located in the area from at least one path reflected by the reflector;
- determine respective angles of arrival of the LOS path and the at least one path reflected by the reflector;
- and
- determine a location of the terminal device by using triangulation based on the respective angles of arrival.
A computer-readable storage medium storing instructions which when executed by at least one processor, cause the at least one processor to perform operations comprising:
- receive a first radio signal of a terminal device located in the area from a line of sight (LOS) path between the antenna array and the terminal device;
- receive a second radio signal of the terminal device located in the area from at least one path reflected by the reflector;
- determine respective angles of arrival of the LOS path and the at least one path reflected by the reflector;
- and
- determine a location of the terminal device by using triangulation based on the respective angles of arrival.
A computer program product comprising instructions which when executed by at least one processor, cause the at least one processor to perform operations comprising:
- receive a first radio signal of a terminal device located in the area from a line of sight (LOS) path between the antenna array and the terminal device;
- receive a second radio signal of the terminal device located in the area from at least one path reflected by the reflector;
- determine respective angles of arrival of the LOS path and the at least one path reflected by the reflector;
- and
- determine a location of the terminal device by using triangulation based on the respective angles of arrival.
