Common Default Beam Across Carrier Groups for Concurrent Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communications systems, determining individual default beams for each component carrier (CC) can lead to compatibility issues, resulting in concurrent communication failures due to incompatible beams across CCs, especially in scenarios involving carrier aggregation.
Innovation Solution
Implementing a common default beam for a CC group, where all CCs within the group share the same beam, such as a default uplink/downlink beam, to ensure compatibility and efficient communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual default beams are determined for each component carrier, then beam-specific optimization can be achieved, but compatibility issues arise resulting in concurrent communication failures
Solution Approach 1:
The patent merges the beam determination process across multiple component carriers by establishing a common default beam for a group of CCs. Instead of independently determining beams for each CC, the system identifies a single default beam that serves multiple CCs simultaneously, eliminating compatibility conflicts while maintaining beam-specific optimization through group-level configuration.
2Reliability
If a common default beam is used for all component carriers in a CC group, then communication reliability improves, but the ability to optimize each CC individually is reduced
Solution Approach 1:
The patent segments component carriers into groups (CC groups) where each group shares a common default beam. This segmentation allows the system to balance between individual optimization and group-level compatibility by creating intermediate layers of beam management, where CCs within the same group benefit from a common beam while different groups can have different default beams.
3Ease of operation
If default beams are configured for individual component carriers, then precise beam control is achieved, but device complexity increases due to beam prioritization requirements
Solution Approach 1:
The patent makes the common default beam universal across multiple component carriers within a CC group. Instead of requiring separate beam configuration and prioritization logic for each CC, the system uses a single default beam that serves multiple functions across different carriers, simplifying the device operation while maintaining precise beam control at the group level.

AI summary
Wireless communications systems may support identification or determination of a common default beam for a component carrier (CC) group (e.g., such that all CCs of a CC group may be associated with a same default beam). For example, a CC group may be configured or established to include one or more CCs (e.g., for carrier aggregation), where each CC group may share a same analog beamformer. As such, a beam (e.g., a default uplink/downlink beam) may be established as default or common across CCs of a CC group (e.g., versus default beams being configured or established for individual CCs). Such an established default beam of a CC group (e.g., a default beam common to all CCs of a CC group) may include or refer to a default downlink shared channel beam, a default sounding reference signal (SRS) beam, a default downlink control channel beam, etc.
