Wireless Slot Concurrency Handling for UE Power and Throughput
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face interference and performance degradation due to increased demand for mobile broadband access, leading to inefficiencies in resource allocation and power consumption, particularly when handling concurrent operations.
Innovation Solution
Implementing a concurrency handling procedure that specifies priority schemes and intervals for wireless communication operations, allowing UEs to adjust parameters like clock frequency or drop operations to manage concurrent tasks effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the UE increases baseband clock frequency or control voltage to facilitate wideband communication operation, then the communication performance is improved, but the power consumption increases
Solution Approach 1:
The patent implements dynamic parameter adjustment by allowing the UE to flexibly change baseband clock frequency and control voltage based on the number of active component carriers. The system transitions between different operating states (e.g., from first operating state with lower frequency to second operating state with higher frequency) depending on workload, thereby optimizing performance while minimizing power consumption during low-activity periods
Solution Approach 2:
The patent directly changes physical parameters (baseband clock frequency and control voltage) to match system demands. When fewer component carriers are active, the system reduces these parameters to lower power consumption; when more carriers are active, parameters are increased to maintain communication performance, creating a direct correlation between operational load and parameter settings
2Use of energy by moving object
If the UE limits the quantity of component carriers used during operation, then the power consumption is reduced, but the throughput performance decreases
Solution Approach 1:
The system dynamically adjusts the number of active component carriers based on traffic conditions and channel quality. Rather than statically limiting carriers, the UE can activate or deactivate carriers as needed, allowing throughput to scale with demand while keeping power consumption proportional to actual usage. This dynamic carrier management resolves the contradiction by making carrier quantity adaptive rather than fixed
3Productivity
If the UE performs both wireless communication operation and measurement operation concurrently using different frequency resources, then the operational efficiency is improved, but parameter adjustment complexity increases
Solution Approach 1:
The patent segments frequency resources into distinct sets (first set for communication, second set for measurements) that can be independently managed. By allocating separate frequency resources for different operations, the system avoids interference while maintaining concurrent execution. This segmentation simplifies parameter management compared to attempting to share resources, as each operation has dedicated resources with stable parameters
Data Source
AI summary
In some aspects, an apparatus includes a processing system including one or more processors and one or more memories coupled to the one or more processors. The processing system is configured to receive scheduling information indicating a wireless communication operation scheduled for a slot. The scheduling information further indicates that the wireless communication operation is scheduled to use at least a first set of frequency resources. The slot is further associated with one or more measurement operations to be performed using at least a second set of frequency resources. The processing system is further configured to perform, during the slot, one or more of the wireless communication operation or the one or more measurement operations in accordance with a concurrency handling procedure.
