Radio Resource Configuration for 5G Terminal Buffer Overflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
5G terminals experience buffer overflow due to mismatched cache configuration and high data transmission rates, leading to frequent data retransmissions and resource wastage, affecting service quality.
Innovation Solution
A data transmission method where network access devices receive physical configuration information, including memory size and read-write speed, from terminals to determine target radio resource configuration parameters, ensuring matched data transmission rates and preventing buffer overflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high order MIMO, multicarrier aggregation, high order modulation coding, or large bandwidth are configured to achieve ultra-high transmission rate, then the data transmission rate is improved, but the terminal experiences buffer overflow due to mismatch between cache configuration and read-write speed
Solution Approach 1:
The patent changes the parameter configuration approach by having the terminal report its physical configuration information (memory size, read-write speed) to the network access device. The network access device then determines target radio resource configuration parameters that are matched to the terminal's actual capabilities, rather than using fixed high-order configurations. This dynamic parameter adjustment resolves the contradiction by adapting the transmission rate to the terminal's buffer handling capacity.
2Speed
If high rate data transmission is configured without considering terminal physical configuration, then transmission speed is improved, but frequent data retransmission occurs due to buffer overflow
Solution Approach 1:
The patent applies preliminary action by having the terminal proactively report its physical configuration information (memory size, read-write speed) to the network access device before data transmission begins. This advance information allows the network access device to pre-determine appropriate radio resource configuration parameters that match the terminal's capabilities, preventing buffer overflow and subsequent retransmissions before they occur.
3Loss of energy
If mismatched radio resource configuration is used, then system resources are wasted due to frequent retransmissions, but configuring appropriate parameters requires additional information exchange
Solution Approach 1:
The patent applies self-service by enabling the terminal to autonomously determine and report its own physical configuration information (memory size, read-write speed) to the network access device. This self-reported information allows the network access device to automatically determine matched radio resource configuration parameters without requiring complex manual configuration or extensive information exchange, reducing both resource waste and configuration complexity.
Data Source
AI summary
A data transmission method and apparatus. The method includes: receiving physical configuration information of a terminal sent by the terminal, in which the physical configuration information includes a memory size and/or a read-write speed of the memory; determining target radio resource configuration parameters matching the physical configuration information; and transmitting data to the terminal using the target radio resource configuration parameters.
