Two-Receiver XR Device Frequency Band Access via Type Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently classifying and permitting connections for two-receiver extended reality (XR) devices, which have specific RF requirements different from legacy devices, leading to restricted access to certain frequency bands.
Innovation Solution
Implementing a method where two-receiver XR devices signal their device type to the network, including MIMO operation layers and RFSP/SPID parameters, allowing the network to configure connections on frequencies reserved for four-receiver devices, such as those between 2.5 GHz and 5 GHz, by determining the device type through home subscriber server (HSS) or user data management (UDM) subscription data.

Engineering Contradiction Analysis
1Reliability
If two-receiver XR devices are restricted from accessing frequency bands reserved for four-receiver devices, then RF requirement compliance is maintained, but device operational capabilities and network access flexibility are reduced
Solution Approach 1:
The patent changes the device classification parameter from purely hardware-based (receiver count) to a composite parameter that includes both hardware capabilities and device type identification. By introducing device type signaling (XR device identification) and using this as a parameter to modify frequency band access rules, the system allows 2Rx XR devices to access 4Rx reserved bands while maintaining RF compliance through proper capability indication to the network.
2Ease of operation
If device type signaling is implemented to identify XR devices, then network can configure appropriate connections, but device complexity and signaling overhead increase
Solution Approach 1:
The patent makes existing signaling mechanisms multi-functional by using device type indication fields to serve dual purposes: both identifying XR device status and conveying capability information for network configuration. This universal approach allows a single signaling element to accomplish multiple tasks (device identification, capability indication, and network configuration trigger) without adding separate dedicated signaling channels, thereby reducing overall signaling overhead.
3Device complexity
If legacy device classification methods are used, then system simplicity is maintained, but XR devices cannot access optimized frequency bands for enhanced reality applications
Solution Approach 1:
The patent introduces dynamic device classification that adapts based on device type identification. Instead of a static classification system based solely on receiver count, the network dynamically determines appropriate frequency band access and configuration parameters based on the signaled device type (XR vs. legacy). This dynamic approach allows the system to optimize performance for XR applications while maintaining simplicity for legacy devices, achieving productivity improvement without proportionally increasing system complexity.
