Solution Overview

Problem

Existing wireless communication systems face challenges in efficiently managing energy allocation for uplink transmissions across multiple communication links, particularly in scenarios where regulatory RF safety requirements impose constraints on RF emissions, leading to inefficiencies and potential violations of exposure limits.

Innovation Solution

A method and apparatus for a user equipment (UE) to identify available energy for uplink transmissions, configure energy allocations based on control traffic parameters and priority of data, and allocate a first and second set of energy allocations to manage energy use effectively across communication links, ensuring compliance with RF safety regulations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If energy is allocated to multiple communication links simultaneously, then data transmission capacity is improved, but RF safety exposure limits may be violated

Engineering Contradiction:
Improvedata transmission capacityVSAvoidRF safety exposure
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent segments the total available energy into two distinct sets: a first set of energy allocations reserved for control traffic parameters and a second set for data transmission. This segmentation allows the system to guarantee minimum energy for safety-critical control functions while distributing remaining energy to multiple communication links, thereby maintaining both high data transmission capacity and compliance with RF safety exposure limits.

Inventive Principle:
Principle #1Segmentation

2Reliability

If energy is prioritized for control traffic, then reliability of control communication is improved, but available energy for data transmission is reduced

Engineering Contradiction:
Improvecontrol communication reliabilityVSAvoiddata transmission throughput
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent applies preliminary action by first configuring the first set of energy allocations for control traffic parameters before allocating energy for data transmission. This ensures that control communication reliability is guaranteed in advance, and only after this reservation is made does the system allocate the second set of energy allocations to data channels, optimizing throughput within the remaining energy budget.

Inventive Principle:
Principle #10Preliminary action

3Use of energy by moving object

If energy allocations are configured based on requested amount and priority, then energy efficiency is improved, but system complexity increases

Engineering Contradiction:
Improveenergy efficiencyVSAvoidenergy management complexity
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The patent changes the parameter of energy allocation from a single unified allocation to a multi-parameter system that considers control traffic parameters, requested amount of energy, and data priority. By introducing these additional parameters and configuring energy allocations accordingly, the system achieves improved energy efficiency while managing complexity through structured configuration approaches.

Inventive Principle:
Principle #35Parameter changes

AI summary

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify an available energy for uplink transmission of a plurality of communication links of the UE. The UE may configure, from the available energy, a first set of energy allocations for the plurality of communication links. The UE may configure a second set of energy allocations for one or more communication links of the plurality of communication links, wherein the second set of energy allocations are allocated from a remainder of the available energy after the first set of energy allocations are allocated. The UE may transmit based at least in part on at least one of the first set of energy allocations or the second set of energy allocations. Numerous other aspects are described.
