Multi-Panel Uplink Power Allocation by Transmit Panel Priority
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems do not effectively allocate available transmit power on a per-transmit panel basis for multi-panel uplink transmissions, failing to consider priority levels of different transmit panels when performing uplink transmissions.
Innovation Solution
The UE and its associated base station determine a priority order for transmit panels and allocate available transmit power accordingly, enabling per-transmit panel priority considerations for multi-panel uplink transmissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If transmit power is allocated without per-panel priority considerations, then power allocation is simple, but transmission efficiency is reduced
Solution Approach 1:
The patent segments the transmit power allocation process into per-panel priority assessments. Each transmit panel is evaluated independently based on its priority level, allowing differentiated power distribution across multiple panels rather than treating them as a single unit. This segmentation enables the system to optimize transmission efficiency by allocating more power to high-priority panels while maintaining manageable complexity through standardized priority-based rules.
2Loss of energy
If per-transmit panel priority allocation is implemented, then power allocation efficiency is improved, but allocation complexity increases
Solution Approach 1:
The patent applies local quality by assigning different priority levels and power allocation characteristics to different transmit panels based on their specific requirements. Each panel receives power allocation treatment tailored to its local conditions and priority status, rather than applying a uniform allocation strategy. This approach maximizes power utilization efficiency by directing more power to panels with higher priority transmissions while reducing allocation complexity through clear priority-based differentiation.

AI summary
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine that a multi-panel uplink transmission is to be performed by the UE, the multi-panel uplink transmission using at least a first transmit panel and a second transmit panel of the UE. The UE may identify a priority order for performing uplink transmissions of the multi-panel uplink transmission from the UE, the priority order including priority levels associated with the first transmit panel and the second transmit panel. The UE may identify an available transmit power for the multi-panel uplink transmission. The UE may perform, according to the priority order, the multi-panel uplink transmission using at least the first transmit panel at a first transmit power and the second transmit panel at a second transmit power, the first transmit power and the second transmit power based at least in part on the available transmit power.
