UE Duty Cycle Reporting for Fallback Power Class Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, there are ambiguities in determining the evaluation period and duration of power classes for user equipment (UE), leading to uncertainties in uplink power control, especially in cases involving non-overlapped sub-band full duplex operations, which affect efficient network resource management and scheduling decisions.
Innovation Solution
User equipment (UE) reports duration information to a base station, including evaluation and fallback durations, to facilitate determining whether a duty cycle exceeds a maximum threshold, allowing for uplink transmission with a fallback power class, thereby enhancing power class utilization and resource efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE applies default power class requirements when duty cycle exceeds threshold, then power control reliability is improved, but ambiguity in evaluation period determination worsens
Solution Approach 1:
The patent segments the power control process into distinct phases: evaluation period determination, duty cycle calculation, and power class application. By introducing specific signaling messages that carry evaluation period configuration from base station to UE, the system divides the ambiguous decision-making process into structured, traceable steps with clear information flow.
Solution Approach 2:
The patent implements feedback mechanisms where the UE reports duty cycle measurements and power class application status back to the base station. This feedback loop allows the base station to adjust evaluation period configurations and duty cycle thresholds based on actual network conditions and UE behavior, resolving ambiguities through iterative optimization.
2Productivity
If non-overlapped sub-band full duplex is applied, then resource utilization efficiency is improved, but uncertainty in duty cycle calculation worsens
Solution Approach 1:
The patent applies local quality by enabling different duty cycle calculation methods for different sub-bands. In non-overlapped sub-band full duplex operation, the UE calculates duty cycle separately for uplink sub-bands and downlink sub-bands, allowing precise local measurement of uplink symbol percentage in each sub-band while maintaining overall resource utilization efficiency.
Solution Approach 2:
The patent introduces frequency domain dimensionality to the duty cycle calculation by considering sub-band specific parameters. Instead of a single system-wide duty cycle threshold, the system evaluates duty cycle in the frequency dimension (per sub-band) while maintaining time dimension evaluation, enabling more accurate determination for full duplex operations.

AI summary
The present disclosure describes methods, system, and devices for determining statistical information. The method includes reporting, by a user equipment (UE), a duration to a base station, wherein: the reported duration indicates, to the base station, at least one of an evaluation duration, a fallback duration and a starting time, and the fallback duration corresponds to a fallback power class applied that is a lower transmission power than a declared or supported power class. The method may further include determining, by the UE, whether a duty cycle during the evaluation duration is larger than a maximum duty cycle, and in response to determining that the duty cycle is larger, sending, by the UE, uplink transmission with the fallback power class, wherein the fallback power class comprises one of a reduced power class and a default power class.
