Common Beam Group Indication for Higher-Quality NR Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In new radio (NR) technologies, high-frequency channel attenuation is fast, necessitating beam-based transmission to ensure network coverage, but existing methods result in poor signal quality due to ambiguity in determining specific common beam groups for transmission.
Innovation Solution
A beam indication method and apparatus that involves receiving and transmitting control signaling to determine a target common beam within a specific common beam group, using various signaling types to establish a correlation between the target common beam and its corresponding group, thereby improving signal quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If beam-based transmission is used to ensure network coverage in high-frequency channels, then network coverage is improved, but signal quality deteriorates due to terminal devices' inability to determine the specific common beam group
Solution Approach 1:
The patent segments the beam indication process by introducing separate indication mechanisms for different beam groups. Control signaling is divided into first control signaling for indicating a first common beam group and second control signaling for indicating a second common beam group, allowing terminal devices to precisely determine the target beam group and improve signal quality while maintaining network coverage
Solution Approach 2:
The patent introduces control signaling as an intermediary carrier that conveys beam group indication information from the network side to terminal devices. This intermediary mechanism enables terminal devices to accurately identify the target common beam group, resolving the signal quality issue while preserving the network coverage benefits of beam-based transmission
2Area of stationary object
If multiple common beam groups are used for transmission, then network coverage is enhanced, but device complexity increases due to the inability to determine the specific beam group for transmission
Solution Approach 1:
Control signaling serves as an intermediary that simplifies the beam group determination process. Instead of requiring terminal devices to complexly analyze multiple beam groups, the control signaling directly indicates the target beam group, reducing device complexity while enabling the use of multiple beam groups for enhanced network coverage
Solution Approach 2:
The system enables terminal devices to autonomously determine the target common beam group by receiving and processing control signaling indications. This self-service mechanism eliminates the need for complex external coordination or additional device complexity, allowing terminal devices to independently identify the correct beam group for transmission

AI summary
A beam indication method includes: receiving first control signaling, where the first control signaling is configured to determine a target common beam, and the target common beam is configured to transmit a member in a first target common beam group; and transmitting at least one member in the first target common beam group by the target common beam.
