Wireless Repeater Beam Management via Priority Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems, particularly in 5G and beyond, face challenges in efficiently managing multiple beams within the same time resource for network-controlled repeaters (NCRs), which is essential for secure coverage in millimeter wave bands.
Innovation Solution
A method and apparatus for beam management in a wireless repeater, where the repeater receives resource set information from multiple base stations, selects one resource set with higher priority based on overlapping time resources, and performs communication using the selected beam.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple beams are allocated within the same time resource for NCR operations, then coverage extension capability is improved, but beam selection complexity increases
Solution Approach 1:
The base station performs preliminary beam allocation and configures multiple resource sets with associated beams before NCR operations begin. Each resource set is pre-associated with specific time resources and beam parameters, so when time resource overlap occurs, the NCR can directly select based on pre-configured priority relationships without complex real-time calculations
Solution Approach 2:
The base station acts as an intermediary that manages the complexity of multi-beam operations. It receives beam allocation information from multiple base stations, determines priority relationships between overlapping resource sets, and provides resolved beam selection instructions to the NCR. This intermediary role centralizes the complex decision-making logic at the base station rather than requiring the NCR to independently resolve beam conflicts
2Ease of operation
If single beam operation is maintained in existing NR standard, then implementation simplicity is preserved, but multi-user support capability is limited
Solution Approach 1:
The system segments beam resources into multiple independent resource sets, each associated with specific time resources and users. Each resource set maintains its own beam configuration and priority level, allowing the system to support multiple users and beams while keeping each individual resource set's management relatively simple and modular
Solution Approach 2:
The beam allocation system transitions from static single-beam operation to dynamic multi-beam operation. The base station can dynamically adjust which beams are active, their associated time resources, and their priority relationships based on current network conditions and user requirements, enabling flexible multi-user support while maintaining operational simplicity through centralized control

AI summary
A method of a repeater may comprise: receiving, from a first base station, first resource set information associated with a first beam; receiving, from a second base station, second resource set information associated with a second beam; in response to that a first time resource indicated by the first resource set information overlaps with a second time resource indicated by the second resource set information, selecting one resource set information having a higher priority among the first resource set information and the second resource set information; and performing communication with a terminal using one beam associated with the one resource set information in a resource indicated by the one resource set information.
