Solution Overview
Problem
Current wireless communication systems face challenges in optimizing transmit power based on multi-antenna modes and quality of service profiles, leading to inconsistent service quality across different wireless devices.
Innovation Solution
The system configures wireless devices with power control parameters that adjust transmit power based on selected multi-antenna modes and associated profiles, prioritizing higher quality of service devices by increasing the likelihood of power requests and reconfiguring devices to optimize frame error rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transmit power is uniformly increased for all wireless devices, then service quality is improved, but energy consumption increases and system efficiency deteriorates
Solution Approach 1:
The patent applies local quality by differentiating power control parameters based on specific device profiles and multi-antenna modes. High-priority devices receive aggressive power control parameters that increase transmit power more readily, while low-priority devices receive conservative parameters. This localized differentiation ensures that energy consumption is optimized for each device's specific service quality requirements rather than applying uniform power control across all devices.
Solution Approach 2:
The patent implements dynamics by making power control parameters adaptive to changing conditions. The base station monitors device profiles, multi-antenna mode selections, and channel conditions, then dynamically adjusts power control parameters in real-time. This allows the system to increase power only when and where needed to maintain service quality, rather than maintaining constantly high power levels across all devices.
2Reliability
If power control parameters are adjusted to prioritize high-quality service devices, then service quality for those devices is improved, but fairness to other devices may deteriorate
Solution Approach 1:
The patent applies parameter changes by modifying power control parameters based on device profiles and multi-antenna modes. Different parameter sets are assigned to different device categories, allowing the system to optimize service quality for high-priority devices while maintaining acceptable service for other devices. The parameters include thresholds and scaling factors that are adjusted according to device-specific requirements rather than applying identical parameters to all devices.
3Reliability
If the system reconfigures devices to request more power increases, then frame error rates are improved, but overall system power consumption increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring power control parameters based on device profiles and expected multi-antenna mode selections. The base station anticipates which devices will need power increases and pre-sets their power control parameters to be more aggressive. This preliminary configuration allows devices to maintain lower frame error rates without requiring continuous power increases, thereby reducing overall system power consumption while still achieving reliable communication.
Data Source
AI summary
A wireless device is configured with a power control parameter having a first value. The first power control parameter determines whether the wireless device requests an increase in transmit power from a base station. A profile is determined to be associated with the wireless device. An indicator selecting a multi-antenna mode is received from the wireless device. Based on the profile and the indicator, the wireless device is configured with the power control parameter having a second value.
