Multi-DCI Cell Scheduling to Exceed Single-Control Coding Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems are limited to scheduling physical channels in a maximum of four cells using a single piece of downlink control information (DCI), exceeding the coding capacity and restricting simultaneous scheduling of more cells, which affects power consumption and system efficiency.
Innovation Solution
Implement a scheduling method using both a first and a second signaling to exceed the coding capacity of a single signaling, where the first signaling is used to achieve simultaneous scheduling of more physical channels or cells, thereby enabling simultaneous scheduling of more physical channels or cells, improving scheduling efficiency and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single piece of DCI is used to schedule physical channels, then the coding capacity is充分利用, but the maximum number of cells that can be scheduled is limited to four
Solution Approach 1:
The patent divides the scheduling function into multiple independent DCI messages (first DCI and second DCI). The first DCI schedules a first set of cells, while the second DCI schedules a second set of cells. This segmentation allows the system to schedule more than four cells by distributing scheduling information across multiple DCI messages, each operating within the existing coding capacity limits.
2Adaptability or versatility
If multiple DCI messages are used to schedule more cells, then the number of schedulable cells increases, but the power consumption of the terminal device increases
Solution Approach 1:
The patent implements dynamic scheduling where the network device can flexibly configure whether to use single DCI or multiple DCI messages based on the actual number of cells requiring scheduling. When the number of cells exceeds four, the system dynamically switches to multiple DCI mode, and the terminal device dynamically adjusts its blind detection behavior based on reception of the first DCI, optimizing power consumption according to actual scheduling needs.
Solution Approach 2:
The terminal device performs blind detection on the second DCI only after successfully receiving and processing the first DCI. The first DCI contains information about the first quantity of cells it schedules, which the terminal device uses to determine whether to continue with blind detection for additional DCI messages. This feedback mechanism allows the terminal to avoid unnecessary blind detection and reduce power consumption when the number of scheduled cells is within the single DCI capacity.
3Productivity
If the DCI carries scheduling information for more cells, then the system efficiency improves, but the information bits exceed the coding capacity
Solution Approach 1:
The patent segments the scheduling information into multiple DCI messages. Each DCI message carries scheduling information for a subset of cells (maximum four cells per DCI), staying within the coding capacity limit. The first DCI carries scheduling information for a first quantity of cells, and the second DCI carries scheduling information for a second quantity of cells, allowing the total number of scheduled cells to exceed four while each individual DCI remains within capacity constraints.

AI summary
The present application relates to the field of communications, and discloses a scheduling method and apparatus, a device, and a storage medium. The method comprises: receiving a first signaling, information indicated by the first signaling comprising a first number; and receiving the first number of a second signaling. The first signaling and the second signaling are used to schedule a second number of physical channels or cells. The first number is an integer greater than or equal to 0, and the second number is a positive integer. Simultaneous scheduling of more physical channels or cells is supported, thus scheduling efficiency is improved, reliability is increased, power consumption waste caused by meaningless blind detection is prevented, and the utilization efficiency of transmission resources is improved.
