Beam Control Method for Base Station Channel Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication technologies face challenges in efficiently managing different physical channels, such as access, control, and traffic channels, due to the lack of a general beam management method, leading to increased access scheduling complexity and reduced transmission reliability.
Innovation Solution
A beam control method is introduced that configures specific types of beams for different physical channels, including common and traffic beams, and identifies transceiving reciprocity relationships to optimize beam training and scheduling, allowing for reduced access scheduling and improved signal quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a general beam management method is not implemented, then beam training and scheduling complexity increases, but transmission reliability decreases
Solution Approach 1:
The patent segments beam management into channel-specific beam types (common beams for synchronization and random access, dedicated beams for data transmission). This segmentation allows each beam type to be optimized independently for its specific function, reducing overall system complexity while improving transmission reliability through specialized beam handling.
Solution Approach 2:
The patent establishes transceiving reciprocity relationships that allow a single beam configuration to serve multiple purposes. The network device can determine uplink beam information from downlink beam information through reciprocity, enabling one beam to function for both downlink transmission and uplink reception, thereby reducing the number of separate beam training procedures needed.
2Reliability
If beam training is performed for all channels, then transmission reliability improves, but beam training time increases
Solution Approach 1:
The patent extracts and separates the beam training requirements for different channel types. Common beams are used for initial access and synchronization without requiring dedicated beam training, while dedicated beams are only trained when specifically needed for data transmission. This extraction eliminates redundant beam training operations and reduces overall training time while maintaining signal quality where critical.
Solution Approach 2:
The patent performs preliminary beam configuration by establishing common beams during initial access before dedicated data transmission begins. This preliminary action of setting up common beams with transceiving reciprocity relationships prepares the system in advance, so that when dedicated beams are needed, the beam training can be more efficient since the basic beam directions are already established.
3Reliability
If separate beams are used for each channel type, then transmission reliability improves, but device complexity increases
Solution Approach 1:
The patent creates a universal beam management framework where common beams serve multiple channel types (synchronization channels, random access channels) and where transceiving reciprocity allows the same beam configuration to be used for both uplink and downlink. This universality reduces the number of separate beam configurations needed while maintaining reliability through appropriate beam selection for each channel type.
