Solution Overview

Problem

There is a need for improved methods and apparatuses to efficiently configure positioning protocol sessions in wireless communication systems, particularly in next-generation wireless access technologies like New Radio (NR), to support enhanced mobile broadband communication, massive machine type communication, and ultra-reliable and low latency communication, especially in scenarios involving vehicle-to-everything (V2X) communications.

Innovation Solution

A method and apparatus for a user equipment (UE) to exchange positioning parameters, establish positioning sessions based on location requests, and reuse existing sessions under certain conditions, such as time thresholds or successful location acquisition, to optimize wireless signal transmission and reception.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a new positioning session is established for each location request, then positioning accuracy and reliability are improved, but signaling overhead and system resource consumption increase

Engineering Contradiction:

Improvepositioning reliabilityVSAvoidsignaling overhead

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The patent merges multiple positioning sessions by allowing a second positioning session to reuse parameters from a first positioning session when conditions are satisfied. This combines the parameter exchange and session establishment processes, reducing redundant signaling overhead while maintaining positioning reliability through conditional parameter reuse.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent enables positioning parameters established in one session to serve multiple purposes by being reused in subsequent sessions under certain conditions. This multi-functionality allows the same parameters to support multiple location requests, reducing the need for repeated parameter exchange and lowering signaling overhead.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Measurement precision

If positioning parameters are exchanged for every location request, then positioning precision is improved, but transmission time and latency increase

Engineering Contradiction:

Improvepositioning precisionVSAvoidpositioning latency

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent performs parameter exchange in advance during the first positioning session and stores these parameters for future use. When a second location request arrives, the pre-exchanged parameters can be reused if conditions are met, eliminating the need for repeated parameter exchange and reducing positioning latency.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent creates a copy of positioning parameters from the first session for use in the second session. Instead of re-exchanging parameters, the system copies and reuses the existing parameter set under certain conditions, maintaining positioning precision while significantly reducing the time required for parameter exchange.

Inventive Principle:

Principle #26Copying

3Adaptability or versatility

If multiple positioning sessions are established simultaneously, then support for multiple location requests is improved, but device complexity and session management overhead increase

Engineering Contradiction:

Improvemulti-request supportVSAvoidsession management complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges the management of multiple positioning sessions by enabling parameter sharing between sessions. Instead of independently managing each session's parameters, the system combines parameter storage and retrieval mechanisms, allowing multiple sessions to share common parameter sets and reducing overall management complexity.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

The present disclosure relates to a method for performing positioning by a user equipment (UE) in a wireless communication system. Specifically, the method comprises the steps of: on the basis of receiving a first location request, exchanging at least one positioning parameter with a first peer entity; on the basis of the at least one positioning parameter, establishing a first positioning session related to the first location request; and on the basis that a second location request is received from a second peer entity and at least one positioning session reuse condition is satisfied, establishing a second positioning session related to the second location request on the basis of the at least one positioning parameter related to the first positioning session.
