Solution Overview
Problem
Existing communication systems fail to ensure timely transmission of service data with specified delay requirements, leading to degraded user experience due to alternate signal transmission among terminal devices.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If signals from different terminal devices are alternately transmitted to achieve fairness, then system capacity is increased, but service data with time validity requirements cannot be transmitted within specified delay requirements
Solution Approach 1:
The patent changes the scheduling parameter from fixed alternate transmission to dynamic priority-based transmission. The network device determines transmission priority based on the quantity of to-be-transmitted frames, allowing parameters to change dynamically based on actual service needs rather than following a fixed alternating pattern.
Solution Approach 2:
The patent introduces dynamic scheduling where transmission priority is not fixed but changes based on the quantity of to-be-transmitted frames. The network device continuously adjusts which terminal device transmits next based on real-time frame quantities, making the system adaptive rather than static.
2Ease of operation
If alternate transmission is used among terminal devices, then fairness is achieved, but user experience is degraded due to delay violations
Solution Approach 1:
The patent changes the scheduling parameter from fixed alternate transmission to dynamic priority-based transmission. The network device determines transmission priority based on the quantity of to-be-transmitted frames, allowing parameters to change dynamically based on actual service needs rather than following a fixed alternating pattern.
Solution Approach 2:
The patent implements feedback mechanisms where terminal devices report the quantity of to-be-transmitted frames to the network device. The network device uses this feedback information to dynamically adjust transmission priorities, creating a closed-loop control system that responds to actual service conditions.
3Productivity
If scheduling is based on channel quality and historical transmission rate, then resource allocation is optimized, but time validity requirements of service data are not met
Solution Approach 1:
The patent changes the scheduling parameter from fixed alternate transmission to dynamic priority-based transmission. The network device determines transmission priority based on the quantity of to-be-transmitted frames, allowing parameters to change dynamically based on actual service needs rather than following a fixed alternating pattern.
Solution Approach 2:
The patent applies preliminary action by having terminal devices report the quantity of to-be-transmitted frames in advance before actual transmission scheduling. This allows the network device to proactively prioritize transmissions that are likely to miss delay requirements, rather than reacting after delays have occurred.

AI summary
This application provides a communication method, to schedule a signal of a terminal device based on a quantity of to-be-transmitted frames of the terminal device. In the method, a network device receives N pieces of first information, where the N pieces of first information are respectively used to determine quantities of to-be-transmitted frames of N terminal devices, and N is an integer greater than 1; and the network device sends signals to or receives signals from M terminal devices among the N terminal devices based on priorities of the N terminal devices, where the priorities of the N terminal devices are determined based on the quantities of to-be-transmitted frames of the N terminal devices, the signals of the M terminal devices are used to carry a part or all of to-be-transmitted frames of the M terminal devices, and M is an integer less than or equal to N.
