Relay Communication Priority Handling for Time-Domain Conflicts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network Controlled Repeaters (NCR) face challenges in determining control information application during time-domain conflicts, such as overlapping beam indications, leading to ineffective relay communication.
Innovation Solution
A method for relay communication that determines control information priorities based on communication signaling or predefined rules to resolve time-domain conflicts, ensuring appropriate control information application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the relay device receives multiple control information pieces simultaneously, then the system coverage and relay communication capability are improved, but time-domain conflicts occur among control information leading to inability to select appropriate beam information
Solution Approach 1:
The patent changes the parameter of control information by introducing priority levels (first priority and second priority). The network device marks control information with different priorities, and the relay device uses these priority parameters to resolve time-domain conflicts by selecting higher-priority control information, thus managing multiple control information pieces effectively without complexity increase.
2Reliability
If the relay device applies all received control information, then complete control coverage is achieved, but conflicting control information cannot be properly resolved leading to communication failures
Solution Approach 1:
The network device performs preliminary action by assigning priority levels to control information before transmission. The relay device receives pre-marked control information with priority indicators, enabling immediate resolution of time-domain conflicts without additional processing time or communication delays.
3Ease of operation
If the relay device selects control information without priority indication, then device simplicity is maintained, but correct beam information selection during conflicts becomes impossible
Solution Approach 1:
The priority indication acts as an intermediary element between the network device and relay device. Instead of complex selection algorithms, the priority indication mediates the control information selection process, allowing the relay device to automatically and accurately select the correct beam information during conflicts while maintaining operational simplicity.
