Transceiver Reconfiguration Mechanism for Carrier Aggregation

Solution Overview

Problem

In communication networks, especially those using carrier aggregation, there is a challenge in managing discontinuity in transmission and reception due to the need for reconfiguration of transceiver systems, particularly when activating or deactivating secondary cells or alternate communication links, leading to issues like power consumption, data rate reduction, and retransmissions.

Innovation Solution

A mechanism is introduced where the user equipment (UE) communicates with the network to schedule a controlled reconfiguration period, allowing for a UE reconfiguration period to be scheduled by the network based on UE requests, thereby minimizing uncontrolled discontinuity and optimizing power consumption and data transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If transceiver system reconfiguration is performed when activating or deactivating secondary cells, then communication link reliability is improved, but transmission discontinuity increases leading to power consumption increase and data rate reduction

Engineering Contradiction:

Improvecommunication link reliabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The network schedules a reconfiguration period in advance before the actual transceiver reconfiguration occurs. This preliminary scheduling allows the system to prepare for the reconfiguration event, coordinate resource allocation, and minimize the impact on ongoing transmissions by planning the reconfiguration timing ahead of time rather than performing it immediately when secondary cells are activated or deactivated.

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The network schedules a reconfiguration period in advance before the actual transceiver reconfiguration occurs. This preliminary scheduling allows the system to prepare for the reconfiguration event, coordinate resource allocation, and minimize the impact on ongoing transmissions by planning the reconfiguration timing ahead of time rather than performing it immediately when secondary cells are activated or deactivated.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The reconfiguration procedure is executed within a specifically scheduled and limited time period. By rushing through the reconfiguration process within the allocated reconfiguration period, the system minimizes the duration of transmission discontinuity, allowing quick transition through the reconfiguration state and resuming normal data transmission as soon as possible.

Inventive Principle:

Principle #21Skipping (Rushing through)

3Adaptability or versatility

If uncontrolled reconfiguration periods occur, then transceiver system adaptability is improved, but network capacity is reduced due to frequent retransmissions and discontinuity

Engineering Contradiction:

Improvetransceiver system adaptabilityVSAvoidnetwork capacity

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The reconfiguration period scheduling is dynamic rather than fixed. The network can adjust the timing, duration, and frequency of reconfiguration periods based on current network conditions, traffic load, and UE requirements. This dynamic approach allows the system to adapt transceiver reconfiguration to changing conditions while minimizing the overall impact on network capacity through intelligent scheduling control.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system implements feedback mechanisms where the network monitors the impact of reconfiguration events on transmission performance and adjusts future reconfiguration scheduling accordingly. By receiving feedback on retransmission rates and transmission discontinuity, the network can optimize the timing and frequency of reconfiguration periods to balance transceiver adaptability with network capacity maintenance.
