Coordinating UE Intra-UECS Packet Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless network communications between user equipment (UE) and base stations can be degraded by signal strength loss, bandwidth limitations, and interfering signals, particularly for UEs at the cell edge, where conventional techniques like User Equipment-Coordination Set (UECS) may not fully address latency and reliability issues, especially in scenarios without infrastructure or with blockages.
Innovation Solution
Intra-UECS communication methods where a coordinating UE allocates air interface resources to other UEs, receives and routes Internet Protocol (IP) data packets, and transmits them to their destinations within the UECS, using techniques like joint transmission and reception, demodulation, and I/Q sampling to enhance signal quality and reliability.

Engineering Contradiction Analysis
1Reliability
If conventional UECS techniques are used for cell edge communications, then some signal quality degradations are remedied, but latency and reliability issues persist especially without infrastructure or with blockages
Solution Approach 1:
The patent introduces an intermediary routing mechanism where the coordinating UE acts as a mediator to route packets between UEs in the coordination set. The coordinating UE receives packets from one UE, determines the destination, and forwards them to the appropriate UE, enabling reliable communication even when direct connections are unavailable due to blockages or infrastructure absence.
Solution Approach 2:
The patent implements dynamic resource allocation where the coordinating UE dynamically assigns air interface resources to different UEs based on communication needs. This dynamic scheduling allows the system to adapt to changing conditions, optimize latency by allocating resources to the most needed connections, and maintain reliability through flexible resource management.
2Reliability
If air interface resources are allocated for intra-UECS communication, then reliable low-latency communication is achieved, but resource management complexity increases
Solution Approach 1:
The patent merges the resource allocation function into the coordinating UE, which already has a established role in managing UECS communications. By combining resource allocation with the existing coordinating UE functions, the system avoids introducing separate complex resource management infrastructure while still achieving reliable low-latency communication.
Solution Approach 2:
The coordinating UE performs self-service by autonomously determining packet routing decisions and allocating air interface resources based on destination addresses and communication needs. This self-service approach eliminates the need for external centralized control, reducing overall system complexity while maintaining reliable communication.
3Reliability
If the coordinating UE routes packets through I/Q sampling and demodulation, then signal quality and link budget improve, but processing requirements increase
Solution Approach 1:
The coordinating UE is designed to perform multiple functions including packet routing, resource allocation, and signal processing (I/Q sampling and demodulation). By making the coordinating UE multi-functional, the system improves signal quality and link budget without requiring separate dedicated processing units for each function, thus managing processing requirements efficiently.

AI summary
Methods, devices, systems, and means for intra-UECS communication by a coordinating user equipment, UE, in a user equipment-coordination set, UECS, are described herein. The coordinating UE allocates first air interface resources to a second UE and second air interface resources to a third UE for intra-UECS communication. The coordinating UE receives, using the allocated first air interface resources, an Internet Protocol, IP, data packet from the second UE in the UECS. The coordinating UE determines that a destination address included in the IP data packet is an address of the third UE and transmits, using the allocated second air interface resources, the IP data packet to the third UE.
