Multi-Panel Uplink Scheduling via Base Station Collision Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G wireless communication systems, there is a challenge in efficiently managing uplink communication when a terminal uses multiple panels simultaneously, as existing technologies lack effective methods for the terminal to report changes in the uplink communication environment to the base station.
Innovation Solution
A method is proposed where a terminal determines the number of panels to use for uplink communication and reports relevant information to the base station, allowing the base station to schedule uplink communication accordingly. This involves obtaining scheduling offset values and information on uplink transmissions to avoid collisions and optimize communication.

Engineering Contradiction Analysis
1Productivity
If a terminal uses multiple panels simultaneously for uplink communication, then communication capacity and transmission reliability are improved, but the complexity of managing uplink transmissions and avoiding collisions increases
Solution Approach 1:
The base station determines whether uplink transmissions from multiple panels will collide and provides feedback information to the terminal. This feedback mechanism enables the terminal to adjust its transmissions based on the base station's assessment, resolving the complexity of collision management while maintaining multi-panel communication capacity.
Solution Approach 2:
The base station adjusts scheduling offset values for different panels based on collision determination. By dynamically changing the timing parameters (scheduling offsets) of uplink transmissions, the system manages multi-panel complexity through parameter optimization rather than structural complexity.
2Adaptability or versatility
If the terminal reports detailed information about panel usage and transmission conditions, then the base station can optimize scheduling, but the amount of information reporting and processing overhead increases
Solution Approach 1:
Instead of requiring the terminal to report all possible transmission parameters and conditions, the invention extracts only the essential information needed for collision determination. The base station performs the heavier processing by determining collisions based on received transmission parameters, reducing terminal reporting overhead while maintaining scheduling optimization capability.
Solution Approach 2:
The base station acts as an intermediary that receives minimal transmission parameter information from the terminal and performs the complex collision determination and scheduling optimization centrally. This mediator approach shifts processing burden from the terminal to the base station, reducing information reporting requirements.
3Reliability
If the base station performs collision determination for all uplink transmissions, then transmission reliability is improved, but the processing time and computational resources required increase
Solution Approach 1:
The base station performs collision determination in advance before scheduling uplink transmissions. By proactively identifying potential collisions and adjusting scheduling offsets beforehand, the system ensures transmission reliability without adding processing time during actual transmission periods. The preliminary action eliminates the need for real-time collision resolution.
