UE Power Saving via Bandwidth Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User equipment (UE) experiences high power consumption when communicating via New Radio (NR) or fifth generation (5G) radio access technologies, particularly due to larger bandwidths associated with higher frequency ranges, and existing power-saving techniques are inadequate in managing this issue effectively.
Innovation Solution
The UE is enabled to selectively perform or refrain from performing procedures with NR/5G cells based on channel-by-channel bandwidth thresholds, allowing it to connect with lower frequency range channels to minimize power consumption, by identifying trigger conditions such as low power or throughput states and comparing channel bandwidths with predefined thresholds to decide on actions like refraining from measuring reference signals or reporting measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the UE communicates via NR/5G radio access technologies with higher frequency ranges and larger bandwidths, then the data throughput and communication capability are improved, but the power consumption at the UE increases significantly
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the UE's communication parameters based on power state. When power consumption exceeds a threshold, the UE transitions from high-bandwidth NR/5G communication to lower bandwidth modes or LTE communication. This changes the operational parameters (bandwidth, radio access technology) to resolve the contradiction between throughput and power consumption.
Solution Approach 2:
The patent implements dynamics by making the communication mode adaptable and changeable in real-time. The UE continuously monitors its power consumption state and dynamically switches between different communication technologies (NR/5G vs. LTE) and bandwidth configurations. This dynamic adaptation allows the system to optimize the trade-off between productivity and energy usage based on current conditions.
2Reliability
If the UE performs procedures with high-bandwidth NR/5G channels, then the communication capability is enhanced, but the power consumption increases and may cause procedure failure
Solution Approach 1:
The patent applies preliminary action by checking the power state before initiating communication procedures. The UE evaluates whether it has sufficient power reserves before attempting to establish high-bandwidth NR/5G connections. This preliminary assessment prevents initiating procedures that would likely fail due to power constraints, thereby maintaining reliability while managing power consumption.
Solution Approach 2:
The patent implements preliminary anti-action by proactively preventing power-consuming procedures when the power state is insufficient. Before the UE attempts to perform communication procedures, it checks power conditions and refrains from initiating high-bandwidth procedures when power is low. This preemptive measure counteracts the potential harmful effect of power depletion and procedure failure.
3Use of energy by moving object
If the UE refrains from completing procedures with high-bandwidth channels to save power, then power consumption is reduced, but the communication efficiency and throughput may be compromised
Solution Approach 1:
The patent applies parameter changes by adjusting communication parameters based on power state. Instead of completely avoiding NR/5G communication, the UE modifies parameters such as bandwidth configuration and radio access technology selection. When power is sufficient, the UE uses high-bandwidth NR/5G channels for optimal throughput. When power is low, it transitions to lower bandwidth modes or LTE, thus maintaining communication efficiency within power constraints.
Solution Approach 2:
The patent implements dynamics by creating a flexible, state-dependent communication strategy. The UE continuously adapts its communication behavior based on real-time power state assessment. This dynamic approach allows the system to maximize communication efficiency when power is available while automatically reducing activity to preserve power when energy is constrained, optimizing the trade-off between productivity and energy usage.

AI summary
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to receive a downlink transmission from a first cell, where the downlink transmission includes information for performing one or more actions associated with a second cell. The UE may identify a satisfaction of a trigger condition associated with one or more parameters at the UE based on a power level of the UE being less than or equal to a threshold power level, a throughput at the UE being less than or equal to a threshold throughput, or both. The UE may additionally identify at least one bandwidth associated with the second cell based on a previous wireless connection. The UE may compare, the at least one bandwidth associated with the second cell with a threshold bandwidth. The UE may then perform at least one action associated with a procedure based on the comparing.
