Solution Overview

Problem

Current wireless communication systems face challenges in efficiently transitioning between antenna port modes and transmission modes, leading to suboptimal battery life and resource utilization, as well as increased complexity in signaling between wireless communication devices and base stations.

Innovation Solution

A method is introduced where wireless communication devices can autonomously transition from multiple antenna port mode to single antenna port mode, implicitly or explicitly notifying the base station, and the base station reallocates resources accordingly, using radio resource control signaling to manage these transitions and optimize power allocation based on antenna gain imbalance and battery status.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If wireless communication devices use multiple antenna port mode, then communication reliability is improved, but battery consumption increases and device complexity increases

Engineering Contradiction:

Solution Approach 1:

The patent implements dynamic switching between single antenna port mode and multiple antenna port mode based on real-time channel conditions and quality metrics. The wireless communication device monitors channel quality indicators (CQI) and reference signal received power (RSRP), and autonomously transitions between transmission modes to adapt to varying channel conditions, thereby maintaining communication reliability while reducing battery consumption during poor channel conditions

Inventive Principle:

Solution Approach 2:

The patent changes the operational parameters of the antenna port configuration by transitioning between different transmission modes (single antenna port mode and multiple antenna port mode). This parameter change allows the system to optimize performance by selecting the appropriate mode based on channel conditions, quality metrics, and battery status, thus resolving the contradiction between reliability and energy consumption

Core Design Contradiction:

Solution Approach 1:

The patent enables the wireless communication device to autonomously determine and execute transitions between single antenna port mode and multiple antenna port mode based on its own measurements of channel conditions and quality metrics. The device self-manages the mode transition process by monitoring CQI, RSRP, and battery status, and autonomously selecting the appropriate transmission mode without requiring complex explicit signaling from the base station, thus reducing signaling complexity while maintaining adaptability

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent implements a feedback mechanism where the wireless communication device continuously monitors channel quality indicators (CQI) and reference signal received power (RSRP), and uses this feedback information to autonomously determine when to transition between transmission modes. This feedback-driven approach enables adaptive mode selection while minimizing the need for complex explicit signaling, as the device makes decisions based on its own measurements and reports only essential information to the base station

Inventive Principle:

Solution Approach 1:

The patent enables the wireless communication device to perform preliminary assessments of channel conditions, quality metrics, and battery status before transitioning between transmission modes. By conducting these preliminary evaluations autonomously, the device can make informed mode transition decisions without requiring extensive explicit signaling and resource allocation from the base station, thus improving resource utilization while maintaining sufficient control precision through the device's own measurements and decisions

AI summary

A wireless communication device may autonomously transition from a multiple antenna port mode to a single antenna port mode. The wireless communication device may implicitly notify a base station about the autonomous transition from the multiple antenna port mode to the single antenna port mode. The base station may reallocate resources that were previously allocated to the wireless communication device but that are no longer being used by the wireless communication device. In some cases, the base station may configure the wireless communication device's antenna port mode via radio resource control signaling.
