Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G communication systems face challenges in optimizing power consumption and resource allocation for diverse use cases such as eMBB, URLLC, and mMTC, particularly in scenarios requiring ultra-low latency and high reliability, leading to inefficient battery usage and increased power consumption.
Innovation Solution
Implementing a user equipment (UE) that receives a configured-resources skipping indication to skip processes related to uplink resource grants and semi-persistent downlink resource configurations during a configured-resources skipping time period, optimizing power saving procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE continuously monitors and processes configured uplink resource grants and semi-persistent downlink resource configurations, then communication reliability is maintained, but power consumption increases
Solution Approach 1:
The patent implements periodic skipping of configured resources where the UE is indicated to skip processing for specific periods. The base station provides skipping indications that tell the UE to skip monitoring and processing for configured uplink resource grants and semi-persistent downlink resource configurations during designated time periods, transforming continuous monitoring into periodic action to reduce power consumption while maintaining reliability through controlled skipping intervals
Solution Approach 2:
The patent directly applies the skipping principle by allowing the UE to skip processing of configured resources when not needed. The configured-resources skipping indication mechanism enables the UE to rush through or bypass the monitoring and processing steps for uplink resource grants and downlink resource configurations during skipping periods, significantly reducing power consumption without compromising communication reliability when resources are actually needed
2Use of energy by moving object
If the UE skips processing for configured resources to save power, then power efficiency improves, but communication latency may increase
Solution Approach 1:
The patent implements dynamic skipping control where the base station provides skipping indications that can be adjusted based on real-time communication needs. The skipping duration and frequency are dynamically controlled, allowing the system to adapt between power-saving mode (longer skipping periods) and low-latency mode (shorter or no skipping periods), thus balancing power efficiency and communication latency requirements
Solution Approach 2:
The patent employs feedback mechanisms where the base station monitors UE activity and communication needs to determine optimal skipping patterns. The feedback loop allows the system to adjust skipping indications based on actual traffic conditions, ensuring that latency is minimized when data transmission is active while maximizing power savings during idle periods, thereby resolving the contradiction between power efficiency and communication latency

AI summary
The present disclosure relates to a user equipment. UE, comprising the following. A receiver receives, from a base station, a configured-resources skipping indication, wherein the configured-resources skipping indication indicates that the UE is allowed to perform one or more of the following actions: —skipping a process related to one or more configured uplink resource grants, and —skipping a process related to one or more semi-persistent, SPS, downlink resource configurations. A processing circuitry of the UE skips, in response to the received configured-resources skipping indication, the one or more processes during a configured-resources skipping time period.
