Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If NR devices support full features and complex configurations, then capability and functionality are improved, but power consumption and resource usage increase
Solution Approach 1:
The patent segments device capabilities into different categories (full-featured NR devices and RedCap devices) with distinct capability sets. RedCap devices are configured to support only a subset of NR features, allowing them to operate with reduced power consumption while maintaining essential functionality. This segmentation enables the network to treat different device types differently in terms of configuration and resource allocation.
Solution Approach 2:
The patent introduces capability indication parameters that allow devices to signal their supported feature sets to the network. Based on these parameters, the network dynamically adjusts configuration parameters such as bandwidth, numerology, and feature sets assigned to each device. This parameter-based approach enables flexible adaptation of device capabilities to match actual device hardware and power constraints.
2Adaptability or versatility
If NR devices handle full features, then functionality is improved, but device complexity increases
Solution Approach 1:
The patent divides the feature set into multiple categories, with RedCap devices supporting a segmented subset of features. This segmentation reduces the complexity burden on devices with limited capabilities while maintaining full functionality for devices that require it. The network manages different feature sets through standardized signaling mechanisms.
Solution Approach 2:
The patent implements dynamic capability indication where devices signal their supported features, and the network dynamically adjusts configurations based on these indications. This dynamic approach allows the system to adapt to varying device capabilities without requiring complex static configuration management, simplifying the overall system while maintaining flexibility.
3Adaptability or versatility
If NR devices support all features, then capability is improved, but resource wastage increases
Solution Approach 1:
The patent applies partial action by configuring RedCap devices to support only the necessary subset of features required for their specific applications. Instead of enabling all NR features universally, the system activates only the required features for each device type, reducing unnecessary resource consumption and energy wastage while maintaining adequate functionality.
Solution Approach 2:
The patent uses capability indication parameters to trigger corresponding configuration changes in the network. When a device indicates RedCap capabilities, the network automatically adjusts resource allocation parameters, bandwidth configurations, and feature sets to match the device's actual needs, thereby eliminating resource wastage associated with over-provisioning full-featured configurations.

AI summary
Various aspects of the present disclosure generally relate to configurations for new radio (NR) devices with reduced capabilities. In some aspects, a user equipment (UE) may determine a configuration from stored configuration information, where the configuration specifies a subset of features that NR UE with reduced capabilities is to support. The UE may communicate according to the configuration of reduced capabilities, or fall back to a set of further reduced UE capabilities. Numerous other aspects are provided.
