Dynamic Uplink Transmission Cycle Adjustment for Wireless Resource Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies and resource wastage due to low allocation and utilization of uplink resources, particularly in situations where terminals do not have data to transmit, leading to suboptimal resource allocation and increased latency.
Innovation Solution
A method where a network device dynamically adjusts the transmission cycle for uplink resources based on the transmission state of the terminal device, shortening the cycle when data is received and lengthening it when no data is sent, thereby optimizing resource allocation and reducing waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed transmission cycle is used for uplink resources, then resource allocation is simple, but resource utilization is low and radio resources are wasted when terminals have no data to transmit
Solution Approach 1:
The patent implements dynamic adjustment of the transmission cycle for uplink resources. The network device monitors the transmission state of the terminal and adjusts the cycle length accordingly: using a first (shorter) cycle when data is detected and a second (longer) cycle when no data is present. This dynamic adaptation resolves the contradiction by making the system flexible rather than fixed, improving resource utilization without excessive complexity.
Solution Approach 2:
The patent changes the time parameter (transmission cycle duration) based on the terminal's data transmission state. By switching between different cycle configurations (first cycle vs. second cycle) depending on whether data is present, the system optimizes resource allocation efficiency and reduces waste while maintaining manageable complexity through state-based parameter adjustment.
2Loss of time
If uplink resources are allocated frequently to ensure fast data transmission, then transmission latency is reduced, but resource allocation overhead increases
Solution Approach 1:
The patent dynamically adjusts the transmission cycle based on actual data transmission needs. When data is detected, a shorter first cycle is used to enable fast transmission and reduce latency. When no data is present, the cycle is extended to a second (longer) cycle, reducing allocation overhead. This dynamic approach resolves the contradiction by adapting the cycle length to actual traffic conditions.
Solution Approach 2:
The network device monitors the transmission state of the terminal (feedback mechanism) and adjusts the transmission cycle accordingly. This feedback-driven approach ensures that resources are allocated frequently enough to maintain low latency when needed, while reducing allocation overhead during idle periods, thus resolving the contradiction between latency and efficiency.
3Speed
If dedicated resource allocation based on SPS mechanism is used, then fast data transmission is achieved, but UL grant assignment efficiency is low causing radio resource waste
Solution Approach 1:
The patent makes the transmission cycle dynamic rather than fixed as in traditional SPS. The network device adjusts between a first cycle (for fast transmission when data is present) and a second cycle (for resource conservation when idle). This resolves the contradiction by maintaining fast transmission capability when needed while avoiding resource waste during idle periods.
Solution Approach 2:
The patent changes the transmission cycle parameter based on the terminal's data transmission state. By switching between different cycle configurations, the system achieves fast data transmission when required while improving UL grant assignment efficiency and reducing radio resource waste during idle periods, thus resolving the contradiction.

AI summary
Disclosed is a method for wireless communication, a network device, and a terminal device. The method includes: sending, by a network device, configuration information to a terminal device, the configuration information instructing the terminal device to perform uplink data transmission according to a first transmission cycle; and determining, by the network device, a second transmission cycle for subsequent uplink data transmission of the terminal device according to data transmission of the terminal device on a transmission resource based on the first transmission cycle. In this way, allocation efficiency and utilization of uplink transmission resources can be improved, thereby avoiding waste of radio resources.
