Pre-scheduling Cancellation via Alternative Frequency Band
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data transmission in pre-scheduling manner is prone to interference from other devices using the same frequency band, leading to transmission failures, especially in high-delay-sensitive services like multiplayer online battle arena (MOBA) games.
Innovation Solution
The method involves the first device receiving a pre-scheduling message from the second device, which includes parameters for pre-scheduling transmission. Instead of waiting for the pre-scheduling moment, the first device transmits uplink or downlink target data and indication information using a different frequency band before the pre-scheduling moment, allowing for cancellation of the pre-scheduling transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If pre-scheduling transmission is used to reduce redundancy and improve efficiency, then data transmission efficiency is improved, but transmission reliability deteriorates due to interference from other devices
Solution Approach 1:
The patent applies preliminary action by having the terminal device send indication information before the pre-scheduling moment to notify the network device of potential interference or transmission issues. This allows the network device to take preliminary measures to adjust scheduling parameters or switch to alternative frequency bands, thereby maintaining transmission reliability while preserving the efficiency benefits of pre-scheduling.
Solution Approach 2:
The patent implements feedback by establishing a communication mechanism where the terminal device sends indication information back to the network device about transmission conditions. This feedback loop enables the network device to monitor transmission quality and adjust scheduling decisions in real-time, resolving the contradiction between pre-scheduling efficiency and transmission reliability.
2Measurement precision
If pre-scheduling moment is fixed to ensure timing accuracy, then transmission timing precision is improved, but adaptability deteriorates when interference occurs
Solution Approach 1:
The patent applies dynamics by making the transmission schedule adjustable rather than fixed. The network device can modify the pre-scheduling moment or switch to alternative frequency bands based on real-time interference conditions. This dynamic adjustment mechanism maintains timing precision when conditions are favorable while providing adaptability when interference occurs, resolving the contradiction between fixed timing and flexible adaptation.
Solution Approach 2:
The patent implements parameter changes by allowing the network device to modify scheduling parameters such as the pre-scheduling moment or frequency band selection based on transmission conditions. This enables the system to maintain timing accuracy when interference is absent while adapting to changing conditions when interference occurs, thus resolving the contradiction between precision and adaptability.
3Device complexity
If data transmission waits for pre-scheduling moment, then scheduling simplicity is improved, but transmission delay increases when interference causes failure
Solution Approach 1:
The patent applies preliminary action by having the terminal device send indication information before the pre-scheduling moment, allowing the network device to prepare alternative transmission plans in advance. This prevents transmission delays by proactively adjusting schedules before interference occurs, while maintaining scheduling simplicity through automated network device coordination.
Solution Approach 2:
The patent implements feedback by establishing a communication mechanism where the terminal device notifies the network device of transmission conditions before the scheduled moment. This feedback enables the network device to adjust timing and avoid delays, resolving the contradiction between simple scheduling and minimal transmission delay by automating the adjustment process.

AI summary
An embodiment of the present application discloses a transmission processing method and device, and an apparatus and a storage medium, wherein the method is applied to a first apparatus, comprising: receiving a pre-scheduling message sent by a second apparatus through a first channel; reading, from the pre-scheduling message, a pre-scheduling time and a pre-scheduling frequency band used for pre-scheduling transmission of the first apparatus and the second apparatus; before the pre-scheduling time arrives, sending uplink target data and indication information to the second apparatus by using any frequency band other than the pre-scheduling frequency band; and the indication information is used to indicate to cancel the pre-scheduling transmission.
