Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face issues with resource waste and data packet loss due to insufficient or excessive pre-configured resources for services with varying data frame sizes, particularly in XR services with periodic data arrivals.
Innovation Solution
A method for triggering and reporting buffer status reports (BSR) that groups PDUs into sets based on association relationships, and transmitting a remaining data amount, allowing timely resource allocation by the network side.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If too many pre-configured resources are allocated for services with large changes in periodically arrived data frames, then transmission requirements can be satisfied, but resource waste occurs
Solution Approach 1:
The patent implements dynamic resource allocation by allowing the terminal to flexibly adjust the number of transport blocks transmitted based on the actual data amount in each periodic frame. The network device dynamically configures the maximum number of transport blocks, and the terminal adapts its transmission to match the actual buffer status, transforming a static resource allocation into a dynamic one that responds to varying data requirements.
Solution Approach 2:
The patent changes the parameter of transport block quantity from a fixed pre-configured value to a dynamically adjustable parameter. The network device configures a maximum number of transport blocks, and the terminal modifies this parameter based on the actual data amount, enabling efficient resource utilization while satisfying transmission requirements for services with varying data frames.
2Loss of energy
If pre-configured resources are less than data amount in current arriving frame, then resource efficiency is improved, but data packet loss occurs
Solution Approach 1:
The patent applies preliminary action by pre-configuring a maximum number of transport blocks that the terminal can transmit in each periodic opportunity. This preliminary configuration enables the terminal to quickly adapt to varying data amounts without waiting for dynamic scheduling, preventing data packet loss while maintaining resource efficiency through the ability to transmit up to the configured maximum when needed.
Solution Approach 2:
The patent implements dynamic resource allocation by allowing the terminal to flexibly adjust the number of transport blocks transmitted based on the actual data amount in each periodic frame. The network device dynamically configures the maximum number of transport blocks, and the terminal adapts its transmission to match the actual buffer status, transforming a static resource allocation into a dynamic one that responds to varying data requirements.
3Device complexity
If traditional BSR triggering methods are used for periodic services, then simple implementation is achieved, but timely resource allocation cannot be ensured for services with large data variations
Solution Approach 1:
The patent applies periodic action by triggering BSR reporting at each periodic transmission opportunity for semi-persistent scheduling. This periodic BSR triggering ensures that the network device receives timely buffer status information for each periodic data frame, enabling timely resource allocation decisions while maintaining the simplicity of periodic scheduling mechanisms.
Solution Approach 2:
The patent implements feedback by having the terminal report the remaining data amount of the PDU set through periodic BSR transmissions. This feedback mechanism provides the network device with real-time information about the buffer status, enabling timely and accurate resource allocation adjustments for services with large data variations while maintaining implementation simplicity.

AI summary
Embodiments of the present invention provide a BSR triggering and reporting method, and a resource allocation method and apparatus. The BSR triggering and reporting method comprises: determining a Packet Data Unit (PDU) set, the PDU set comprising one or more PDUs, and the PDUs in the PDU set having an association relationship; and triggering a BSR, and sending the BSR, the BSR comprising the remaining data volume of the PDU set. By determining the PDU set comprising one or more PDUs having a correlation, and triggering and sending the BSR comprising the remaining data volume, which is not transmitted, in the PDU set, a network side can allocate uplink transmission resources to a terminal in time on the basis of the remaining data volume, thereby ensuring the reliability of data transmission, ensuring low delay requirements of services, and saving resources.
