Unified DCI Format for Scheduling Multiple Transmissions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks are inefficient due to the use of multiple control information formats for scheduling and activating multiple transmissions, which can lead to suboptimal resource allocation and increased complexity.
Innovation Solution
The implementation of a unified DCI format that dynamically indicates parameters for scheduling and activating multiple transmissions, including both downlink and uplink transmissions, across multiple slots, reducing the need for frequent PDCCH monitoring and enabling time-domain multiplexing of transport blocks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple control information formats are used for scheduling and activating multiple transmissions, then the scheduling flexibility is improved, but the device complexity and resource allocation efficiency deteriorate
Solution Approach 1:
The patent merges multiple separate control information formats (DCI format 0_1 for uplink and DCI format 1_1 for downlink) into a single unified DCI format that can schedule both uplink and downlink transmissions. This consolidation reduces the number of different control formats the UE must process and maintain, thereby reducing device complexity while preserving scheduling flexibility through dynamic indication fields within the unified format.
Solution Approach 2:
The unified DCI format is designed to perform multiple functions: it can schedule uplink transmissions, downlink transmissions, both simultaneously, and can indicate multiple transport blocks across different slots. This multi-functionality eliminates the need for separate specialized formats for different transmission types, reducing overall system complexity while maintaining adaptability through dynamic parameter indication.
2Adaptability or versatility
If multiple control information formats are used for scheduling transmissions, then the scheduling adaptability is improved, but the resource allocation efficiency deteriorates
Solution Approach 1:
By combining multiple control information formats into one unified format, the patent reduces overhead and improves resource allocation efficiency. The unified format uses dynamic indication fields to specify transmission parameters, allowing efficient resource utilization without the redundancy of maintaining multiple separate format definitions and processing paths in the network and UE.
3Adaptability or versatility
If multiple control information formats are used for scheduling transmissions, then the transmission versatility is improved, but the PDCCH monitoring requirements increase
Solution Approach 1:
The unified DCI format provides universal scheduling capability for both uplink and downlink transmissions, as well as multiple transport blocks. Since there is only one format to monitor and process, the quantity of control information the UE must monitor is reduced compared to maintaining separate formats for different transmission types, thereby reducing PDCCH monitoring requirements while preserving transmission versatility.

AI summary
Apparatuses, methods, and systems are disclosed for control information that schedules or activates multiple transmissions. One method (1200) includes receiving (1202) user equipment specific signaling from a device. The user equipment specific signaling comprises a control information format that dynamically indicates a set of parameters that schedule or activate at least two transmissions between the user equipment and the device; and the at least two transmissions comprise: a first transmission having a first transmission link direction from the user equipment to the device; and a second transmission having a second transmission link direction from the device to the user equipment.
