Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single uplink resource configuration is used for buffer status reporting, then the device complexity is reduced, but the adaptability to different application requirements deteriorates
Solution Approach 1:
The patent segments the buffer status reporting mechanism into two distinct resource configurations: a first configuration for transmitting the buffer status report itself, and a second configuration for transmitting an indication of buffer status. This segmentation allows each configuration to be optimized independently for different application requirements, resolving the contradiction between simplicity and adaptability.
Solution Approach 2:
The patent introduces dynamic resource allocation where the UE can be configured with multiple uplink resource configurations and selectively use them based on application requirements. The network can dynamically assign different resource configurations for different buffer status reporting scenarios, enabling adaptability while maintaining manageable complexity through structured configuration management.
2Adaptability or versatility
If dual uplink resource configurations are allocated for buffer status reporting, then the adaptability to different applications is improved, but the device complexity increases
Solution Approach 1:
The patent creates a universal resource allocation framework where the dual configuration mechanism can serve multiple purposes: standard buffer status reporting, urgent data transmission indications, and application-specific optimized reporting. This multi-functionality justifies the increased complexity by providing a single versatile mechanism that handles diverse application requirements.
Solution Approach 2:
The patent applies local quality by allowing different resource configurations to have different properties optimized for specific purposes. The first configuration can be optimized for regular reporting with standard parameters, while the second configuration can be optimized for urgent indications with different timing, frequency, or resource allocation characteristics, enabling tailored solutions for different local requirements.
3Productivity
If buffer status reporting is optimized for high data rates, then the productivity is improved, but the latency increases
Solution Approach 1:
The patent implements preliminary action by using the second uplink resource configuration to transmit an indication of buffer status before the actual buffer status report is transmitted through the first configuration. This advance indication allows the network to prepare for upcoming data transmission, reducing the effective latency while maintaining the productivity benefits of optimized buffer status reporting.
Data Source
AI summary
A user equipment (UE) UE includes a transceiver, and a processor operably coupled to the transceiver. The transceiver is configured to receive, from a base station (BS), a first configuration allocating uplink (UL) resources for transmitting a buffer status report, and receive, from the BS, a second configuration allocating UL resources for transmitting an indication corresponding to the buffer status report. The processor is configured to select a first UL resource allocated by the first configuration, and select a second UL resource allocated by the second configuration. The transceiver is further configured to transmit the indication corresponding to the buffer status report in the second UL resource, and transmit the buffer status report in the first UL resource.
