Solution Overview

Problem

Existing communication systems face poor transmission performance due to inadequate processing of BWP switching and concurrent operations such as small data transmission, paging monitoring, and wake-up signal monitoring.

Innovation Solution

A method and apparatus that prioritize either BWP switching or target operations based on preset conditions, ensuring that BWP switching is performed after or before the target operations like small data transmission, paging monitoring, or wake-up signal monitoring.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If BWP switching and target operations (SDT initiation, paging monitoring, PEI monitoring, WUS monitoring, random access, system information receiving) are performed simultaneously without priority rules, then the terminal can attempt all operations, but transmission performance deteriorates due to conflicts and congestion

Engineering Contradiction:
Improvetransmission performanceVSAvoidprocessing complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by establishing priority rules in advance before BWP switching and target operations occur. The network side device configures priority information that determines the execution sequence beforehand, avoiding conflicts during actual operation. This pre-established priority framework enables smooth coordination between BWP switching and operations like SDT initiation, paging monitoring, PEI monitoring, WUS monitoring, random access, and system information receiving without requiring complex real-time decision-making.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If BWP switching is performed without considering concurrent target operations, then BWP switching can proceed independently, but transmission performance deteriorates due to resource conflicts

Engineering Contradiction:
Improvetransmission performanceVSAvoidtime for conflicts and congestion
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent implements feedback mechanisms where the network side device monitors the terminal's execution status of target operations and adjusts BWP switching timing accordingly. The network side device receives feedback about whether the terminal is performing SDT initiation, paging monitoring, PEI monitoring, WUS monitoring, random access, or system information receiving, and uses this information to determine the optimal timing for BWP switching, thereby avoiding resource conflicts and reducing transmission time losses.

Inventive Principle:
Principle #23Feedback

3Productivity

If the terminal performs all target operations during BWP switching without priority management, then operational completeness is maintained, but transmission performance deteriorates due to uncoordinated execution

Engineering Contradiction:
Improvetransmission performanceVSAvoidoperation coordination
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent applies dynamics by making the operation execution sequence flexible and adaptive rather than fixed. The network side device dynamically determines the execution sequence based on real-time conditions, allowing the terminal to switch between BWP switching and target operations (SDT initiation, paging monitoring, PEI monitoring, WUS monitoring, random access, system information receiving) in an optimized order. This dynamic adjustment simplifies operation coordination while maintaining transmission performance.

Inventive Principle:
Principle #15Dynamics
