Solution Overview

Problem

Existing communication systems face challenges in efficiently managing bandwidth part (BWP) switching scenarios, particularly during operations like small data transmission (SDT), paging monitoring, and wake-up signal (WUS) monitoring, due to inefficient prioritization and synchronization issues.

Innovation Solution

A method and apparatus for BWP switching that prioritizes either the operation or the switching based on preset conditions, allowing terminals to perform target operations like SDT, paging monitoring, or wake-up signal monitoring before or after switching from a first BWP to a second BWP, optimizing resource allocation and reducing power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the terminal performs both target operation and BWP switching simultaneously, then resource utilization is improved, but processing conflicts and system complexity increase

Engineering Contradiction:
Improveresource utilizationVSAvoidprocessing complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by determining the execution sequence of target operations and BWP switching in advance through preset conditions. The terminal pre-establishes priority rules that specify whether to perform the target operation first or the BWP switching first, based on operation types such as SDT initiation, paging monitoring, and random access. This pre-determined sequencing resolves processing conflicts before they occur, allowing both operations to be efficiently managed without increasing real-time processing complexity.

2Reliability

If the terminal prioritizes target operation over BWP switching, then operation reliability is improved, but switching delay increases

Engineering Contradiction:
Improveoperation reliabilityVSAvoidswitching delay
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies dynamics by making the execution sequence flexible rather than fixed. The terminal dynamically adjusts whether to prioritize the target operation or BWP switching based on preset conditions that consider the specific operation type and system state. For example, for SDT initiation the target operation may be prioritized, while for other operations BWP switching may take precedence. This dynamic sequencing ensures operation reliability when needed while minimizing switching delays through conditional optimization.

3Productivity

If the terminal performs BWP switching first, then resource allocation efficiency is improved, but operation completion time increases

Engineering Contradiction:
Improveresource allocation efficiencyVSAvoidoperation duration
Core Design Contradiction:
ProductivityVSDuration of action of moving object

Solution Approach 1:

The patent applies preliminary action by pre-determining the optimal execution sequence based on the specific operation type and system conditions. The terminal uses preset conditions to decide in advance whether to perform BWP switching first or the target operation first. For operations where resource allocation is critical, BWP switching is prioritized; for time-sensitive operations, the target operation is completed first. This pre-planned sequencing optimizes both resource allocation efficiency and operation duration based on the specific scenario.

AI summary

A BWP switching processing method and apparatus, a configuration sending method and apparatus, and a device are provided. The method includes: obtaining, by a terminal, a target configuration, where the target configuration is a configuration of at least one of a target operation and a bandwidth part BWP; and performing, by the terminal, at least one of the target operation and BWP switching based on the target configuration in a case that a preset condition corresponding to the target operation or a second BWP is met, where the BWP switching includes switching from a first BWP to the second BWP, where in a case that the target operation and the BWP switching are to be performed, the target operation is preferentially performed, and then the BWP switching is performed; or the BWP switching is preferentially performed, and then the target operation is performed.
