5G XR Throughput Feedback to Reduce Repeated Access Requests
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
5G wireless networks may not consistently provide the necessary bandwidth for throughput-intensive extended reality (XR) applications, leading to network congestion and poor user experience due to UE devices repeatedly attempting to access XR services without knowing the network's availability.
Innovation Solution
A system where mobile devices send an indication to the 5G network requesting XR communication, and the base station assesses its capability to provide the required throughput. If incapable, it sends a message to the device, prompting the device to wait or cease requests, reducing repeated attempts and network traffic.

Engineering Contradiction Analysis
1Reliability
If the UE keeps trying to access XR services without knowing network status, then the UE can potentially establish XR communication when network conditions improve, but this causes network congestion and worsens user experience
Solution Approach 1:
The base station sends feedback messages to the UE indicating whether XR services are currently available based on network throughput conditions. This feedback mechanism allows the UE to adjust its service requests according to real-time network status, preventing excessive requests that would cause congestion while ensuring XR services are accessed when conditions are favorable.
Solution Approach 2:
The base station performs preliminary assessment of network conditions and proactively notifies the UE about XR service availability before the UE attempts to access the service. This preliminary action prevents the UE from making unsuccessful access attempts that would contribute to network congestion.
2Loss of energy
If the base station sends repeated rejection messages to the UE, then network traffic is reduced by preventing excessive requests, but this increases signaling overhead and processing load
Solution Approach 1:
Instead of sending rejection messages for every failed access attempt, the base station implements periodic availability notifications where it informs the UE at scheduled intervals whether XR services are currently available. This periodic approach reduces signaling frequency while still providing necessary guidance to the UE, balancing traffic reduction with processing load management.

AI summary
The system determines that an application running user equipment (UE) is requesting a throughput intensive communication over a network. The throughput intensive communication can require a predetermined downlink and uplink throughput. The system sends a first indication to the network, specifying to a base station of the network that the UE is requesting the throughput intensive communication. The base station determines whether it can provide the downlink throughput and the uplink throughput to the UE. Upon determining that the base station cannot provide the downlink or the uplink throughput to the UE, the base station sends a first message to the UE, indicating that the throughput intensive communication is of low quality. Upon receiving the first message, the UE waits for a predetermined criterion to be satisfied before attempting to engage in the throughput intensive communication, thereby reducing network traffic by eschewing sending repeated requests for the throughput intensive communication.
