Acquiring Assisting TRP Location Information for Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in accurately acquiring and exchanging location information of assisting transmission and reception points (TRPs), especially in dynamic environments where TRPs may be mobile or transient, leading to limitations in optimizing network performance and reliability.
Innovation Solution
The method involves identifying and acquiring location information of assisting TRPs, including geographical and spatial information, and transmitting this information between network entities to enhance positioning, beam management, and interference management, using techniques such as global identifiers and location service features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If location information of assisting TRPs is acquired and exchanged between network entities, then positioning accuracy and beam management are improved, but network complexity and information exchange overhead increase
Solution Approach 1:
The location information exchange mechanism serves multiple functions simultaneously: positioning, beam management, and interference management. By making the location information universally applicable across these different network operations, the patent avoids creating separate specialized systems for each function, thereby improving positioning accuracy without proportionally increasing network complexity
Solution Approach 2:
The patent establishes location information acquisition and exchange as a preliminary action that occurs before positioning and beam management operations. By pre-acquiring and distributing location information of assisting TRPs to relevant network entities, the system prepares the necessary data in advance, enabling more accurate positioning and beam management without requiring complex real-time information exchange during critical operations
2Reliability
If location information of mobile or transient TRPs is continuously updated and exchanged, then network reliability is improved, but information exchange overhead and processing load increase
Solution Approach 1:
The patent implements periodic updates of location information for assisting TRPs rather than continuous real-time updates. Network entities exchange location information at predetermined intervals or triggered by specific events such as TRP mobility detection. This periodic approach maintains network reliability by ensuring location information remains sufficiently current while significantly reducing the overhead compared to continuous information exchange
Solution Approach 2:
The assisting TRPs themselves participate in the location information exchange process by providing their own location data to the network. This self-service approach reduces the burden on the network to continuously track and report TRP locations, thereby improving reliability through more accurate self-reported position data while reducing overall information exchange overhead

AI summary
Certain aspects of the present disclosure provide techniques for acquiring location information of an assisting node, such as an assisting transmission and reception point (TRP). The location information may include geographical location information as well as spatial information. The location information may be used to facilitate positioning and other purposes, such as beam management, interference management, and sensing between one or more assisting TRPs and one or more network entities (e.g., a gNodeB (gNB), a user equipment (UE), a central unit (CU), or a distributed unit (DU)). To achieve these purposes, accurate locations of the assisting TRPs are needed. The present disclosure provides techniques for acquiring and exchanging the accurate location information of such assisting TRPs.
