Multi-TRP Resource Allocation for NCJT Interference Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-TRP (mTRP) environments, existing resource allocation schemes fail to account for TRP synchronization, particularly in non-coherent joint transmission (NCJT) scenarios, leading to suboptimal data transmission and increased interference.
Innovation Solution
A method and apparatus for resource allocation in mTRP environments, where a terminal requests and exchanges information with multiple TRPs to determine optimal TRPs for data transmission, using TRP identifiers, RSRP measurements, and resource allocation based on synchronization signal blocks.

Engineering Contradiction Analysis
1Reliability
If existing resource allocation schemes are used in mTRP environments, then resource allocation can be performed, but TRP synchronization is not accounted for leading to suboptimal data transmission and increased interference
Solution Approach 1:
The patent changes the parameters of resource allocation by introducing TRP synchronization considerations. It modifies the resource allocation process to include synchronization status checking and selective TRP usage based on synchronization quality, thereby reducing interference and improving transmission reliability without requiring complete system redesign
Solution Approach 2:
The patent segments the resource allocation process into distinct phases: synchronization status determination, conditional TRP selection, and interference management. By dividing the overall process into manageable segments, it can address TRP synchronization specifically without affecting other resource allocation functions, thus reducing interference while maintaining operational flexibility
2Reliability
If multiple TRPs are used for data transmission, then communication reliability can be improved, but resource allocation complexity increases due to lack of TRP coordination
Solution Approach 1:
The patent introduces a synchronization management mechanism as an intermediary between multiple TRPs. This intermediary layer coordinates resource allocation decisions by evaluating synchronization status and selecting appropriate TRPs, thereby maintaining communication reliability while reducing the complexity that would otherwise arise from uncoordinated multi-TRP operations
Solution Approach 2:
The patent implements dynamic TRP selection based on real-time synchronization status. The system adapts its resource allocation strategy by switching between different TRPs depending on their synchronization state, which simplifies resource management compared to static multi-TRP configurations while maintaining high communication reliability through flexible adaptation
3Productivity
If TRP selection is performed without synchronization consideration, then resource allocation can be performed quickly, but data transmission quality deteriorates due to interference
Solution Approach 1:
The patent performs preliminary synchronization status checking before finalizing resource allocation decisions. By determining TRP synchronization status in advance and pre-evaluating suitable TRPs based on this information, the system can make faster allocation decisions that account for synchronization, thereby maintaining both high productivity and reliable data transmission quality

AI summary
A terminal according to an embodiment disclosed herein may include the steps of: receiving a report request message including TRP selection criteria information from a first TRP communicating with the terminal through a first resource; checking whether first information to be inquired of a second TRP indicated in the received TRP selection criteria information is included; and transmitting a first request message requesting the first information in the received TRP selection criteria information to the second TRP when the first information to be inquired of a second TEP is included.
