Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing 5G NR system lacks an effective solution for scenarios where one cell is scheduled by multiple scheduling cells or one cell schedules multiple cells simultaneously, leading to inefficiencies in PDCCH processing capability allocation.
Innovation Solution
A method for allocating maximum PDCCH processing capability in a terminal device by determining the total quantity of cells based on cell configuration and scheduling information, and allocating resources accordingly to handle scenarios where one cell is scheduled by multiple cells or one cell schedules multiple cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If one cell is scheduled by multiple scheduling cells or one cell schedules multiple cells simultaneously, then scheduling flexibility is improved, but PDCCH processing complexity increases
Solution Approach 1:
The patent segments the PDCCH processing task by introducing a determination module that divides the processing into distinct stages: first determining the total cell quantity, then allocating processing capability accordingly. This segmentation allows the system to handle complex multi-cell scheduling scenarios by breaking down the overall processing complexity into manageable sub-tasks, thereby resolving the contradiction between scheduling flexibility and processing complexity.
Solution Approach 2:
The patent implements dynamic allocation of PDCCH processing capability based on the determined total cell quantity. The allocation module dynamically adjusts the processing capability distribution according to the actual scheduling configuration, enabling the system to adapt to varying scheduling flexibility requirements while maintaining optimal processing efficiency. This dynamic approach resolves the contradiction by making processing complexity adaptive rather than static.
2Adaptability or versatility
If maximum PDCCH processing capability is allocated to handle multiple scheduling scenarios, then scheduling flexibility is improved, but power consumption increases
Solution Approach 1:
The patent applies partial action by allocating PDCCH processing capability proportionally based on the total cell quantity rather than providing full maximum capability to all cells simultaneously. The allocation module distributes the processing capability according to the actual scheduling needs, ensuring that power consumption is optimized by providing only the necessary processing power for the configured scheduling scenarios, thus resolving the contradiction between scheduling flexibility and power consumption.
3Ease of manufacture
If traditional PDCCH processing capability allocation is used, then implementation is simple, but it cannot handle scenarios where one cell is scheduled by multiple cells or one cell schedules multiple cells
Solution Approach 1:
The patent implements preliminary action by introducing a determination module that pre-determines the total cell quantity before PDCCH processing capability allocation. This preliminary determination step enables the subsequent allocation module to properly handle complex scheduling scenarios including multi-scheduling and multi-scheduled configurations. The preliminary action of determining cell quantity provides a foundation that maintains implementation simplicity while enabling enhanced adaptability.
Solution Approach 2:
The patent introduces an intermediary determination module that acts as a mediator between the configuration information and the PDCCH processing capability allocation. This intermediary module determines the total cell quantity based on configuration information, which then guides the allocation process. This intermediary approach maintains implementation simplicity by providing a clear intermediate step while enabling the system to handle diverse scheduling scenarios that traditional direct allocation cannot support.
