Multi-Carrier DCI Bit-Width Definition for Reliable Decoding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G systems, the bit width of indication fields in DCI formats for scheduling multiple data transmissions on multiple carriers is undefined, leading to unsuccessful reception and decoding of scheduling information by terminal devices.
Innovation Solution
A method for determining the bit width of indication fields in DCI formats based on carriers capable of being simultaneously scheduled, ensuring clear definition and accurate transmission of scheduling information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If one DCI schedules multiple data transmissions on multiple carriers, then data transmission efficiency is improved, but the bit width of indication fields becomes undefined causing decoding failure
Solution Approach 1:
The patent changes the parameter of indication field bit width from undefined to clearly defined. It specifies that the bit width shall be determined based on the number of carriers being scheduled, ensuring that terminal devices can correctly decode the scheduling information while maintaining the capability to schedule multiple carriers simultaneously.
2Adaptability or versatility
If indication field bit width is not clearly defined, then flexibility in scheduling is maintained, but terminal devices cannot successfully receive or decode scheduling information
Solution Approach 1:
The patent defines the bit width parameter of indication fields based on the number of carriers scheduled by the DCI. This provides clear guidance for terminal devices to correctly receive and decode scheduling information while maintaining scheduling flexibility through configurable bit widths adapted to different carrier quantities.
