User Terminal SS Block Control Resource Set Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In future radio communication systems like NR, controlling communication based on synchronization signal blocks (SS blocks) can lead to a decline in communication throughput and spectral efficiency due to inadequate research on resource allocation and identification of SS blocks, especially in multi-beam scenarios.
Innovation Solution
A user terminal is equipped with a receiving section to receive synchronization signal blocks and a control section that specifies a control resource set for the downlink control channel needed to receive minimal system information, based on the broadcast channel within a certain synchronization signal block, allowing flexible configuration of control resource sets using explicit mapping, mathematical equations, or beamforming methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If communication is controlled based on SS blocks, then initial access and synchronization can be achieved, but communication throughput and spectral efficiency may decline
Solution Approach 1:
The patent segments the control resource set into multiple candidates, each associated with different SS block indices. The terminal device selects the appropriate control resource set based on the detected SS block index, enabling efficient resource allocation while maintaining high communication throughput. This segmentation resolves the contradiction by organizing control resources in a structured manner that supports both initial access and high-speed communication.
Solution Approach 2:
The patent establishes preliminary mapping relationships between SS block indices and control resource set candidates before actual communication occurs. The network device pre-configures multiple control resource set candidates with their corresponding SS block index mappings, allowing the terminal device to quickly determine the appropriate control resource set after detecting the SS block. This preliminary configuration enables fast initial access while ensuring optimal resource allocation for maintaining high communication throughput.
2Reliability
If communication is controlled based on SS blocks, then synchronization can be established, but spectral efficiency may decline
Solution Approach 1:
The patent changes the parameter of control resource set identification by introducing multiple control resource set candidates indexed by SS block indices. Instead of using a fixed control resource set, the system dynamically selects from multiple candidates based on the detected SS block index. This parameter change ensures reliable synchronization through SS blocks while improving spectral efficiency by optimizing control resource allocation to match actual communication conditions.
3Adaptability or versatility
If multiple control resource set candidates are configured, then resource allocation flexibility increases, but device complexity increases
Solution Approach 1:
The patent enables the terminal device to autonomously determine the appropriate control resource set by using the SS block index it has already detected during initial access. The terminal device applies the detected SS block index to select from the pre-configured control resource set candidates without requiring additional complex signaling or processing. This self-service approach increases resource allocation flexibility while minimizing device complexity, as the selection process leverages existing detection results.
