Solution Overview
Problem
Current wireless communication networks face challenges in efficiently managing bandwidth and resource allocation across diverse user equipment (UE) capabilities and varying network conditions.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If bandwidth parts (BWPs) are implemented for flexible bandwidth adaptation, then network efficiency and power consumption are improved, but device complexity and configuration management become more complex
Solution Approach 1:
The patent divides the total system bandwidth into multiple bandwidth parts (BWPs), each representing a separate configurable bandwidth segment. This segmentation allows the network to allocate specific BWPs to different UEs based on their individual requirements, thereby improving network efficiency while managing complexity through structured division of the frequency resource space
Solution Approach 2:
The patent implements dynamic BWP configuration where BWPs can be activated, deactivated, and switched between different UEs in real-time based on network conditions and traffic demands. This dynamic approach enables the system to adapt bandwidth allocation flexibly, optimizing network efficiency while the configuration management complexity is handled through automated network control mechanisms
2Adaptability or versatility
If dynamic configuration of core sets (CORESETs) is implemented, then resource allocation flexibility is improved, but system complexity and overhead increase
Solution Approach 1:
The patent divides control resource sets into multiple CORESETs, each configured with specific parameters such as frequency location, bandwidth, and duration. This segmentation allows different CORESETs to serve different purposes and different UE groups, enhancing resource allocation flexibility while managing system complexity through structured organization of control resources
Solution Approach 2:
The patent enables dynamic configuration of CORESET parameters including frequency start position, bandwidth size, and time duration. By allowing these parameters to be changed based on network conditions and UE requirements, the system achieves high adaptability in resource allocation while the complexity is managed through standardized parameter sets and configuration protocols
3Use of energy by moving object
If bandwidth adaptation is enabled for different UE categories, then power consumption is reduced, but network coordination and management become more difficult
Solution Approach 1:
The patent applies different BWP configurations to different UE categories based on their specific requirements. Each UE can be assigned to appropriate BWPs that match its service type, mobility characteristics, and power constraints. This local optimization allows power-constrained devices to use narrower BWPs and consume less energy, while the network coordinates management through centralized BWP configuration and switching control

AI summary
A method can include determining, by a wireless device, a first plurality of repetitions of a first preamble scheduled for transmission for a random-access procedure. The method can also include suspending, by a wireless device, a power-ramping counter of a random-access procedure based on not transmitting each repetition of a first plurality of repetitions of a first preamble of the random-access procedure. The method can further include transmitting, by the wireless device, a second preamble with a transmit power that is determined based on the power-ramping counter for the random-access procedure.
