UE Power Allocation for Distributed MIMO Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G New Radio (NR) technologies face challenges in optimizing power allocation and on/off control in distributed Multiple Input Multiple Output (MIMO) systems, leading to inefficiencies in wireless communication, particularly in determining priority orders for time-frequency resources and managing transmission power across multiple channels.
Innovation Solution
A method where User Equipment (UE) determines a priority order among time-frequency resources for uplink channels to base stations and repeaters, allocates transmission power based on this order and a maximum power limit, and selectively turns on/off repeaters to avoid interference, ensuring efficient power usage and network quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transmission power is increased to improve communication reliability, then signal quality improves, but interference to other channels increases and power consumption increases
Solution Approach 1:
The patent applies local quality by allocating different power levels to different uplink channels based on their specific requirements. The UE determines priority orders for different time-frequency resources and channels (direct to base station vs. through repeaters) and assigns transmission power accordingly, ensuring each channel receives appropriate power quality rather than uniform power distribution.
Solution Approach 2:
The patent changes the power allocation parameter dynamically by adjusting transmission power levels based on determined priority orders. The system modifies power distribution parameters across different channels and time-frequency resources, optimizing power usage while controlling interference through parameter adjustment rather than fixed power levels.
2Reliability
If transmission power is increased to improve communication reliability, then signal quality improves, but power consumption increases
Solution Approach 1:
The patent optimizes power consumption by dynamically adjusting transmission power parameters based on determined priority orders for different channels. The UE allocates power efficiently across time-frequency resources, ensuring sufficient power for reliable communication while minimizing excess power consumption through parameter optimization.
3Area of stationary object
If multiple repeaters are activated to improve signal coverage, then coverage area expands, but interference increases and system complexity increases
Solution Approach 1:
The patent applies dynamics by enabling the UE to dynamically determine priority orders and control repeater activation states. The system can switch repeaters between on and off states based on determined priorities and communication conditions, allowing flexible adaptation to changing network conditions while controlling interference through selective activation.
Solution Approach 2:
The patent applies local quality by providing different treatment to different repeaters based on their determined priority orders. Each repeater's activation state and power allocation is optimized independently according to its specific role and priority, ensuring coverage expansion while minimizing interference from unnecessary repeater transmissions.
4Area of stationary object
If multiple repeaters are activated to expand coverage area, then system complexity increases
Solution Approach 1:
The patent reduces system complexity through dynamic priority determination and selective repeater activation. The UE determines priority orders for different channels and controls repeater states accordingly, simplifying the system by activating only necessary repeaters rather than managing all repeaters continuously, thus reducing complexity while maintaining coverage.

AI summary
In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE determines a priority order among a first set of time-frequency resources for a first uplink channel to a base station and one or more second sets of time-frequency resources for one or more second uplink channels to one or more repeaters. The UE allocates transmission power across the first set of time-frequency resources and the one or more second sets of time-frequency resources based on the determined priority order and a maximum transmission power limit. The UE transmits signals to the base station and the one or more repeaters based on the transmission power allocation.
