Terminal Capability Reporting for Multi-Beam NR Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In new radio (NR) systems, terminals with varying transmission capabilities are not accurately scheduled due to the inability of network devices to discern whether they can transmit multiple beams simultaneously, leading to inefficiencies and resource mismanagement.
Innovation Solution
Terminals report their capability to transmit multiple beams simultaneously to network devices, enabling the network devices to configure transmission parameters that match the terminal's capabilities, thereby improving scheduling effectiveness and conserving network resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the network device schedules terminals without knowing their multi-beam transmission capability, then the scheduling process is simple, but the scheduling effectiveness and resource utilization are poor
Solution Approach 1:
The terminal reports its capability information (single-beam or multi-beam transmission capability) to the network device in advance, before the actual scheduling and transmission process. This preliminary action allows the network device to have prior knowledge of terminal capabilities, enabling it to make informed scheduling decisions and allocate resources efficiently without increasing the complexity of the scheduling process itself.
2Reliability
If the terminal transmits only one beam on the same antenna panel, then the device complexity is low, but the link connection robustness is insufficient
Solution Approach 1:
The patent enables different transmission capabilities at different locations or contexts. Specifically, certain antenna panels are configured with multi-beam transmission capability while others maintain single-beam capability. This local differentiation allows the system to achieve improved link robustness through multi-beam transmission where needed, while keeping the overall terminal complexity manageable by not requiring all panels to support complex multi-beam operations simultaneously.
