Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G R16 PRS configurations are static, leading to inefficiencies in signaling overheads and inability to dynamically meet high-precision positioning requirements.
Innovation Solution
Implementing a method where the LMF sends multiple sets of PRS configurations to a base station or TRP, allowing selection of the most suitable configuration based on current positioning needs, thereby reducing signaling overheads while ensuring precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple PDU formats are supported for different service types, then service adaptability is improved, but device complexity increases due to multiple configuration parameters
Solution Approach 1:
The patent applies universality by designing a single PDU configuration parameter that can serve multiple service types (e.g., both eMBB and URLLC). The configuration parameter is designed to be service-agnostic, allowing the same parameter structure to configure PDUs for different services by simply changing the service type indicator, rather than maintaining separate configuration parameters for each service type.
Solution Approach 2:
The patent changes the parameter structure from service-specific multiple parameters to a single unified parameter that adapts its meaning based on the service type. The configuration parameter includes a service type indicator field that determines how the same parameter bits are interpreted for different services, allowing dynamic parameter adaptation without increasing structural complexity.
2Manufacturing precision
If PDU configuration is performed separately for each service type, then service-specific optimization is improved, but processing time increases due to multiple independent procedures
Solution Approach 1:
The patent merges multiple service-specific PDU configuration procedures into a single unified configuration process. Instead of executing separate configuration routines for eMBB, URLLC, and other services, the system uses one configuration procedure that adapts to the target service type through the service type indicator, reducing the number of independent processing steps.
Solution Approach 2:
The patent implements preliminary action by including the service type indicator as the first element in the PDU configuration parameter. This allows the receiving device to immediately identify the target service type and pre-configure the appropriate interpretation rules before processing the remaining configuration bits, eliminating the need for sequential service type detection and procedure selection.
3Measurement precision
If service type indication is added to PDU configuration parameter, then configuration accuracy is improved, but transmission overhead increases
Solution Approach 1:
The patent changes the parameter encoding scheme to include a service type indicator that uses minimal bits (e.g., 2-3 bits) to represent multiple service types. This compact encoding provides precise service type identification while adding only a small amount of overhead to the configuration parameter, rather than using extensive service description fields.
