Scheduling Positioning SIBs via Dedicated SI Parameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks face resource limitations in scheduling Positioning System Information Blocks (SIBs), which restricts the number of positioning assistance data messages that can be broadcasted efficiently.
Innovation Solution
The proposed solution involves a method for improving the scheduling of Positioning System Information Blocks (pSIBs) by introducing a specific scheduling information (pSI) that allows for more pSIBs to be scheduled within an SI window, thereby increasing the capacity for positioning assistance data broadcast.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional scheduling methods are used for Positioning System Information Blocks, then resource allocation is simple, but the capacity for broadcasting positioning assistance data is limited
Solution Approach 1:
The patent segments the positioning system information into multiple Positioning SIBs (pSIBs) that can be scheduled independently. Each pSIB contains specific positioning assistance data, allowing the system to divide and broadcast multiple positioning messages within the same SI window, thereby increasing the quantity of positioning data that can be transmitted without overwhelming the scheduling system
Solution Approach 2:
The patent introduces a new scheduling dimension by defining specific scheduling information (pSI) parameters that operate alongside traditional scheduling mechanisms. This includes new fields in SIB1 that specify pSIB scheduling patterns, allowing the system to schedule positioning data in an additional organizational dimension without fundamentally complicating the existing broadcast framework
2Productivity
If more positioning SIBs are scheduled within an SI window, then the capacity for positioning assistance data increases, but the scheduling complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring scheduling information in SIB1 that defines how subsequent pSIBs should be scheduled. The network node预先 establishes the scheduling pattern, SI window parameters, and resource allocation rules before actual pSIB transmission, allowing multiple pSIBs to be efficiently scheduled without real-time complex decision-making
Solution Approach 2:
The patent changes key scheduling parameters by introducing new configurable fields such as si-PosPeriodicity, si-PosWindowLength, and si-PosOffset. These parameter changes allow flexible adjustment of pSIB scheduling density and timing, enabling higher broadcasting efficiency while maintaining manageable complexity through standardized parameter sets
3Loss of time
If positioning SIBs are transmitted with longer periodicity, then resource consumption is reduced, but the delay in transmitting positioning data increases
Solution Approach 1:
The patent implements periodic action by establishing configurable periodicity patterns for pSIB transmission through the si-PosPeriodicity parameter. This allows the system to transmit positioning assistance data at optimized intervals - frequent enough to minimize delay for time-critical positioning needs, but sparse enough to conserve network resources, with different periodicities applicable to different pSIB types or conditions

AI summary
A wireless device and a method performed therein for receiving scheduled positioning system information from a radio network node. The wireless device and the radio network node operate in a wireless communications network. The wireless device receives, from the radio network node, positioning system information scheduling information (pSI) and at least one out of a scheduling offset and a number of system information messages with positioning system information blocks (pSIMs) per system information (SI) window. Further, the wireless device determines in which subframes one or more pSIMs are scheduled by the radio network node based on the pSI and based on at least one out of the scheduling offset and the number of pSIMs per SI window. Furthermore, the wireless device uses the determined scheduling of the one or more pSIMs for receiving the one or more pSIMs.
