Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Determining how to effectively utilize multiple carriers and wireless communication technologies together in a wireless device in a complementary manner is a complex task, and existing systems struggle with efficient beam configuration and signaling overhead.
Innovation Solution
Implementing common analog beam steering for band groups, where a wireless device reports its beam steering capabilities to a cellular network, allowing the network to configure a common beam for multiple component carriers within a frequency band group, thereby avoiding scenarios where the device is improperly configured and reducing signaling overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If independent beam steering is configured for multiple component carriers, then communication flexibility is improved, but device complexity and capability requirements increase
Solution Approach 1:
The patent segments frequency bands into distinct band groups (e.g., first band group and second band group) where each group shares a common analog beam steering capability. This segmentation allows independent beam steering only between band groups while using a common beam within each band group, thereby reducing device complexity while maintaining communication flexibility across multiple component carriers.
2Loss of information
If common beam is configured for multiple component carriers, then signaling overhead is reduced, but communication flexibility decreases
Solution Approach 1:
By segmenting frequency bands into multiple band groups, the system applies common beam configuration within each band group (reducing signaling overhead) while allowing different beam configurations between band groups (maintaining communication flexibility). This segmented approach resolves the contradiction by applying common beam steering at the appropriate granularity level.
3Productivity
If beam configuration is optimized for each component carrier, then communication performance is improved, but signaling overhead increases
Solution Approach 1:
The patent merges the beam configuration for multiple component carriers within the same band group into a single common beam configuration. This merging reduces signaling overhead while maintaining optimized communication performance for each component carrier through the shared beam, as the common beam is appropriately configured for the characteristics of all component carriers in that band group.

AI summary
Apparatuses, systems, and methods for a wireless device and a cellular base station to support common analog beam steering for band groups. The wireless device may provide an indication of analog beam steering capability of the wireless device to the cellular base station. For example, the wireless device may support a limited number of analog beams for each of one or more band groups. The cellular base station may select beam configuration information for the wireless device based at least in part on the indication of analog beam steering capability of the wireless device. This may include selecting a common beam for multiple component carriers for the wireless device based on the wireless device's analog beam steering capability. The cellular base station may provide the beam configuration information to the wireless device.
