Sony patents method to fix phone location signals blocked by hidden devices
Sony has been granted a patent for a method that helps wireless networks locate devices more accurately. The system tests different signal directions to find interference from unknown nearby devices and switches to a clearer path for the location signal.
In the filing’s own words
A method for a network device in a wireless communication system, comprising: instructing a user equipment to send uplink reference signals to the network device using a first set of beams; measuring transmission quality metrics of the uplink reference signals sent in each beam direction of the first set of beams; and instructing the user equipment to send uplink reference signals to the network device for uplink positioning using a second set of beams based at least on a transmission quality metric of an uplink reference signal sent in at least one beam direction of the first set of beams being lower than a threshold. The second set of beams enables the user equipment to avoid sending uplink reference signals in beam directions that are interfered by a communication link of a hidden node device. The hidden node device is unknown to the network device and the user equipment.
What exactly they claim (claim 1)
1. A network device in a wireless communication system, the network device comprising a processing circuit configured to cause the network device to perform the following operations: instructing a user equipment in the wireless communication system to send uplink reference signals to the network device using a first set of beams; measuring transmission quality metrics of the uplink reference signals sent in each beam direction of the first set of beams; and instructing the user equipment to send uplink reference signals to the network device using a second set of beams based at least on a transmission quality metric of an uplink reference signal sent in at least one beam direction of the first set of beams being lower than a threshold, wherein, the second set of beams enables the user equipment to avoid sending uplink reference signals in beam directions that are interfered by a communication link of a hidden node device, wherein the hidden node device is unknown to the network device and the user equipment.
