Solution Overview

Problem

Existing wireless communication systems face challenges in accurately reporting buffer size ranges using short-format and long-format BSR tables, leading to resource waste and insufficient allocation due to inaccurate reporting.

Innovation Solution

A method where a network device sends a first message to a terminal to instruct the use of either a first or second type of BSR table, ensuring the terminal reports a more accurate buffer size range, thereby facilitating appropriate resource allocation and reducing waste.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the terminal uses a fixed BSR table format (short or long), then the reporting process is simple, but the buffer size range accuracy is insufficient leading to resource allocation inefficiency

Engineering Contradiction:
Improvebuffer size range accuracyVSAvoidBSR reporting complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent introduces dynamic BSR table selection where the terminal can switch between short-format and long-format BSR tables based on buffer size thresholds. The network device configures multiple BSR tables with different granularity levels, and the terminal dynamically selects the appropriate table based on current buffer conditions, making the reporting mechanism adaptive rather than static.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of BSR table format (short vs. long) based on buffer size conditions. When buffer size exceeds a threshold, the terminal switches from short-format to long-format BSR table, changing the reporting parameter to achieve better accuracy. This parameter change allows the system to optimize between brevity and precision based on actual needs.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If the terminal reports buffer status with high precision, then resource allocation becomes accurate, but the reporting overhead and processing complexity increase

Engineering Contradiction:
Improveresource allocation efficiencyVSAvoidreporting processing time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent segments the buffer status reporting into different formats (short and long BSR tables) based on buffer size thresholds. Instead of always using a single comprehensive format, the system divides the reporting into segmented formats - using compact short-format for small buffers and detailed long-format for large buffers, reducing overall processing time and overhead.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies partial action by using only the necessary level of detail for each reporting instance. When the buffer size is small, full detailed reporting is unnecessary - a compact short-format suffices. The terminal performs partial reporting (short format) only when needed, avoiding excessive processing overhead while maintaining sufficient accuracy for resource allocation.

Inventive Principle:
Principle #16Partial or excessive action

3Loss of energy

If the network device allocates resources based on inaccurate BSR reports, then resource waste occurs, but increasing reporting accuracy requires more system complexity

Engineering Contradiction:
Improveresource wasteVSAvoidsystem configuration complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The patent implements preliminary action by having the network device pre-configure multiple BSR tables with different formats and granularity levels before the terminal needs to report. The terminal stores these pre-configured tables and can immediately select the appropriate one based on current buffer conditions without real-time computation, reducing system complexity while enabling accurate resource allocation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent establishes a feedback mechanism where the network device receives BSR reports from the terminal and uses this information to allocate uplink resources appropriately. The feedback loop allows the network to adjust resource allocation based on actual buffer status, reducing resource waste while the pre-configured table selection keeps the system complexity manageable.

Inventive Principle:
Principle #23Feedback

AI summary

Provided in the embodiments of the present disclosure are an information processing method and apparatus, and a storage medium. The information processing method is executed by a network device, and comprises: sending a first message to a terminal, wherein the first message instructs the terminal to send a buffer status report (BSR) according to a first-type BSR table or a second-type BSR table. In the method provided in the present disclosure, the type of a BSR table which is used for BSR reporting of a terminal side can be directly indicated by a network device side, such that when sending a BSR, a terminal can clearly learn about which BSR table of a first-type BSR table and a second-type BSR table is to be used so that a more accurate buffer data volume range can be reported to a network device, so as to facilitate the network device in allocating a suitable number of resources to the terminal, thereby reducing situations of resource waste and/or insufficient resource allocation due to the fact that a buffer data volume range of BSR reporting is inaccurate.
