Uplink Power Feedback for Beam Scheduling and Human-Exposure Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G communication systems, effectively managing maximum power reduction (MPR) to minimize exposure to the human body under different uplink beams is challenging due to the inability of base stations to accurately schedule power reductions based on varying beam orientations and human proximity, leading to degraded uplink transmission performance.
Innovation Solution
A method and apparatus for a first communication node to report power parameter information and uplink channel state information to a second communication node, enabling the second node to schedule power reductions and optimize beam management to minimize human exposure.

1Object-affected harmful factors
If base station implements scheduling based on maximum power reduction for different uplink beams, then human body exposure is minimized, but system complexity increases due to additional reporting and scheduling mechanisms
Solution Approach 1:
The patent implements a feedback mechanism where the first communication node reports power parameter information (including MPR values) and uplink channel state information to the second communication node. This feedback enables the base station to make informed scheduling decisions about uplink beam selection and power allocation, thereby minimizing human body exposure while managing system complexity through structured information exchange.
Solution Approach 2:
The patent applies preliminary action by having the first communication node pre-calculate and report power parameter information including maximum power reduction values for different uplink beams before actual transmission scheduling. This advance preparation allows the base station to select appropriate beams and power levels that minimize human exposure without requiring complex real-time calculations during scheduling decisions.
2Productivity
If detailed power parameter information is reported to enable accurate MPR scheduling, then transmission performance is improved, but uplink signaling overhead increases
Solution Approach 1:
The patent extracts only the essential power parameter information needed for MPR scheduling from the complete set of possible uplink channel state information. Specifically, it reports power parameter information including MPR values and associations with uplink beams, rather than transmitting all possible channel parameters. This selective extraction maintains transmission performance while reducing signaling overhead.
Solution Approach 2:
The patent makes the power parameter information report serve multiple functions: it provides MPR values for human exposure management, identifies associated uplink beams for scheduling decisions, and enables power level optimization. This multi-functionality reduces the need for separate signaling messages, thereby improving uplink transmission performance without proportionally increasing signaling overhead.
