Solution Overview
Problem
The configuration of transmission-reception beam pair scanning in existing communication protocols is inflexible, leading to challenges in dynamically adjusting resources, particularly in millimeter wave communication systems with high propagation loss and beam alignment requirements.
Innovation Solution
A method for flexible dynamic configuration of resource transmission and reception using index configuration information to associate transmission and reception modes, allowing for explicit and configurable beam pair scanning through subset and repeated transmission indices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If transmission-reception beam pair scanning is implemented implicitly by configuring resource control high-level parameters, then the configuration process is simplified, but the flexibility and adaptability of resource configuration deteriorates
Solution Approach 1:
The patent introduces dynamic beam pair scanning configuration where the base station can explicitly indicate different scanning modes (first mode with first reception beam, second mode with second reception beam) through downlink control information. This allows the system to adapt resource configuration flexibly based on channel conditions and traffic requirements, resolving the contradiction between configuration simplicity and resource configuration flexibility.
Solution Approach 2:
The patent changes the configuration parameters from implicit high-level parameters to explicit beam-specific parameters including reception beam indices, reference signal resource indices, and spatial filter configurations. This parameter transformation enables fine-grained control of beam pairs while maintaining manageable complexity through standardized configuration structures.
2Device complexity
If joint transmission-reception beam pair scanning is not explicitly specified in the protocol, then the protocol complexity is reduced, but the measurement precision and beam alignment accuracy deteriorates
Solution Approach 1:
The patent segments the beam pair scanning process into distinct first and second scanning modes, each with specific reception beams and reference signal resources. This segmentation allows explicit protocol specification for each mode while keeping the overall protocol structure organized and manageable, thereby improving beam alignment accuracy without excessive protocol complexity.
Solution Approach 2:
The patent performs preliminary configuration of multiple reception beams and their associated reference signal resources before actual beam pair scanning. The base station pre-configures spatial filters and resource mappings, enabling accurate beam alignment during scanning without requiring complex runtime protocol negotiations.
3Ease of operation
If configuration of transmission-reception beam pair scanning is kept simple, then the ease of operation is improved, but the productivity and dynamic resource adjustment capability deteriorates
Solution Approach 1:
The patent creates a universal configuration framework that supports both first and second beam pair scanning modes through standardized parameters and procedures. The base station can select appropriate modes based on conditions, enabling dynamic resource adjustment for different traffic types and channel states while maintaining ease of operation through consistent configuration interfaces.
Solution Approach 2:
The patent implements feedback mechanisms where terminal devices report measurement results for different beam pairs, and the base station uses this feedback to dynamically adjust resource configuration between first and second scanning modes. This feedback loop enables productive dynamic resource adjustment while keeping operations simple through automated decision-making based on reported metrics.
