Abstract
A method performed by a first device is disclosed that includes sending a light of sight, LOS, determination request to a second device which communicates with the first device, wherein the LOS determination request includes an indication of a dual polarization procedure for Line of Sight (LOS), with the indication of the dual polarization procedure for LOS is used indicating that a same sequence of bits is sent at two polarizations to the same direction; a channel measurement for each of the two received sequences at the two polarizations is compared to determine whether a transmission between the first device and the second is LOS or NLOS.
Claims30
A method comprising:
- sending, by a first device, a line of sight (LOS) determination request to a second device, the LOS determination request including an indication that a dual polarization procedure is supported for LOS determination;
- and
- performing, by the first device, the dual polarization procedure to determine whether a LOS channel exists between the first device and the second device, wherein performing the dual polarization procedure includes communicating wave signals carrying the same sequence of bits using two different polarizations in the same direction between the first device and the second device to determine whether the LOS channel exists between the first device and the second device.
A first device comprising:
- a processor;
- and
- a non-transitory computer readable storage medium storing programming for execution by the processor, the programming including instructions to:
- send a line of sight (LOS) determination request to a second device, the LOS determination request including an indication that a dual polarization procedure is supported for LOS determination;
- and
- perform the dual polarization procedure to determine whether a LOS channel exists between the first device and the second device, wherein the instructions to perform the dual polarization procedure includes instructions to communicate wave signals carrying the same sequence of bits using two different polarizations in the same direction between the first device and the second device to determine whether the LOS channel exists between the first device and the second device.
A method comprising:
- sending, by a first device, a message to a second device, the message including a field indicating that the first device supports a dual polarization procedure for line of sight (LOS) determination, wherein the dual polarization procedure for LOS determination includes communicating wave signals carrying the same sequence of bits using two different polarizations in the same direction between the first device and the second device to determine whether a LOS path exists between the first device and the second device.
A first device comprising:
