Solution Overview

Problem

In future radio communication systems, such as NR, user equipment (UE) faces challenges in controlling panel switching, leading to potential degradation in system performance due to increased power consumption and decreased beam gain when activation/deactivation of panels is not appropriately managed.

Innovation Solution

A terminal is configured with a receiving section to receive instructions for panel activation or deactivation and a control section to perform communication operations using or not using the panel after a predetermined offset period, based on reception timing of information or transmission timing of a delivery confirmation signal, ensuring appropriate panel switching control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If panel switching is not appropriately controlled, then system performance degrades with increased power consumption, but implementing control mechanisms increases device complexity

Engineering Contradiction:
Improvepower consumptionVSAvoidcontrol mechanism complexity
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The patent implements feedback mechanisms where the terminal reports panel status and beam measurement information to the base station, which then provides feedback instructions for panel activation/deactivation. This closed-loop feedback system enables appropriate panel switching control to reduce power consumption while maintaining system performance through coordinated base station- terminal interaction.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The terminal autonomously determines panel activation/deactivation timing by applying an offset period from the reception timing of activation/deactivation instructions. This self-service approach allows the terminal to independently manage panel switching without requiring complex continuous control signaling, thereby reducing overall system complexity while achieving power consumption optimization.

Inventive Principle:
Principle #25Self-service

2Reliability

If panel switching control is implemented, then beam gain is maintained, but the control mechanism increases device complexity

Engineering Contradiction:
Improvebeam gainVSAvoidcontrol mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-configuring multiple panels with different beam directions and activation conditions. The terminal maintains standby panels with pre-established beam configurations, allowing rapid switching to maintain beam gain when needed without requiring complex real-time beamforming calculations during switching operations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The base station acts as an intermediary that coordinates panel switching between multiple terminals. It provides centralized control by sending activation/deactivation instructions based on overall system conditions, simplifying individual terminal complexity while maintaining beam gain through coordinated multi-terminal panel management.

Inventive Principle:
Principle #24Intermediary (Mediator)
