Receive-Beam Usage Cost Sharing for Energy-Efficient Wireless Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communications systems face inefficiencies in optimizing energy efficiency due to a lack of knowledge about usage costs associated with different configurations of user equipment (UE), leading to poor performance and high costs.
Innovation Solution
UEs transmit usage cost messages indicating costs associated with different configurations, allowing network entities to determine optimal configurations balancing energy savings and performance by considering usage costs, and instructing UEs to operate accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network entity configures UE with multiple receive beams to improve performance, then communication reliability is improved, but energy consumption increases
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the quantity of receive beams based on usage cost information. The network entity receives usage cost messages from the UE indicating energy consumption for different beam configurations, then selects the optimal number of beams (e.g., 1, 2, or 4 receive beams) to balance communication reliability with energy efficiency. This resolves the contradiction by making the system adaptable rather than fixed.
2Measurement precision
If the UE uses more receive beams to improve reception quality, then signal reception quality is improved, but device power consumption increases
Solution Approach 1:
The patent implements dynamics by enabling the UE to dynamically adjust its receive beam configuration based on received network instructions and usage cost reports. The UE can switch between different receive beam quantities (1, 2, or 4 beams) depending on the operational scenario, allowing real-time optimization of the trade-off between signal reception quality and power consumption rather than being locked into a static configuration.
3Loss of energy
If the network entity optimizes for energy savings by reducing receive beams, then energy efficiency is improved, but communication performance deteriorates
Solution Approach 1:
The patent applies feedback by implementing a closed-loop system where the UE reports usage cost information (energy consumption metrics) for different receive beam configurations to the network entity. The network entity uses this feedback to make informed decisions about optimal beam configuration, balancing energy efficiency with communication performance based on actual measured data rather than static assumptions.

AI summary
Methods, systems, and devices for wireless communications are described. Generally, the techniques described herein may support balancing of system usage costs with performance. For example, a user equipment (UE) may transmit a usage cost message indicating usage costs associated with each unique set of operating parameters supported by the UE, including a first set of operating parameters associated with a first usage cost and a second set of operating parameters associated with a second usage cost. Each set of operating parameters may further be associated with a respective quantity of receive beams of the UE for operating according to the respective set of operating parameters. Additionally, the UE may receive an indication for the UE to operate according to the first set of operating parameters or the second set of operating parameters based on the first usage cost and the second usage cost.
