POSITIONING MEASUREMENT DERIVATION BASED ON A DECODED PHYSICAL DOWNLINK CHANNEL AND CORRESPONDING MEASUREMENT LATENCY - A simplified explanation of the abstract

This abstract first appeared for US patent application 17906850 titled 'POSITIONING MEASUREMENT DERIVATION BASED ON A DECODED PHYSICAL DOWNLINK CHANNEL AND CORRESPONDING MEASUREMENT LATENCY

Abstract

The patent application describes techniques for wireless positioning. It involves a user equipment (UE) receiving a demodulation reference signal (DMRS) and a physical downlink shared channel (PDSCH) associated with the DMRS. The UE decodes the PDSCH and performs a positioning measurement based on the DMRS and the decoded PDSCH. The UE then reports the positioning measurement or location information derived from it to a location server.

Explanation

• The patent application focuses on wireless positioning techniques.
• A user equipment (UE) receives a demodulation reference signal (DMRS) and a physical downlink shared channel (PDSCH) associated with the DMRS.
• The UE decodes the PDSCH and performs a positioning measurement using the DMRS and the decoded PDSCH.
• The UE reports the positioning measurement or location information derived from it to a location server.

Potential Applications

• This technology can be used in various location-based services, such as navigation systems, asset tracking, and emergency services.
• It can enhance the accuracy and reliability of wireless positioning, improving the overall user experience in location-dependent applications.

Problems Solved

• The techniques described in the patent application address the challenge of accurately determining the position of a user equipment in a wireless network.
• By utilizing the demodulation reference signal and the physical downlink shared channel, the positioning measurement can be performed more effectively and reliably.

Benefits

• The use of demodulation reference signals and physical downlink shared channels improves the accuracy of wireless positioning.
• By reporting the positioning measurement or location information to a location server, the technology enables real-time tracking and monitoring of user equipment.
• The techniques described in the patent application can enhance the performance of location-based services and enable new applications that rely on precise wireless positioning.

Original Abstract Submitted

Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) receives a demodulation reference signal (DMRS) and a physical downlink shared channel (PDSCH) associated with the DMRS, the DMRS and the PDSCH spanning a plurality of symbols of a slot, decodes the PDSCH, performs a positioning measurement based on the DMRS and the decoded PDSCH, and reports, to a location server, the positioning measurement or location information derived at least based on the positioning measurement.
