Solution Overview

Problem

Existing communication systems face inefficiencies due to overlapping reception and transmission periods with discontinuous transmission configurations, leading to unnecessary energy consumption and resource usage in base stations and user equipment.

Innovation Solution

Implementing a mechanism for terminals and network entities to manage discontinuous transmission configurations by indicating DTX/μDTX periods and adjusting behaviors to avoid collisions, including skipping or postponing operations during these periods.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If the network entity applies discontinuous transmission configuration to save energy, then energy consumption is reduced, but transmission reliability deteriorates due to overlapping reception and transmission periods

Engineering Contradiction:
Improveenergy consumptionVSAvoidtransmission reliability
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The terminal receives advance indication of the discontinuous transmission configuration from the network entity, allowing it to prepare and adjust its reception and transmission schedules before the DTX period begins. This preliminary action enables the terminal to avoid overlapping operations and ensure reliable communication during the energy-saving period.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts the terminal's reception and transmission operations based on the indicated discontinuous transmission configuration. The terminal modifies its behavior in real-time to align with the network entity's DTX schedule, preventing overlaps while maintaining communication reliability during energy-saving periods.

Inventive Principle:
Principle #15Dynamics

2Productivity

If the terminal performs reception and transmission operations during discontinuous transmission periods, then communication continuity is maintained, but energy consumption increases due to unnecessary operations

Engineering Contradiction:
Improvecommunication continuityVSAvoidenergy consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The network entity provides feedback information in the form of discontinuous transmission configuration indications to the terminal. This feedback enables the terminal to understand when the network entity will be inactive and accordingly adjusts its operations to avoid unnecessary transmissions and receptions during these periods, thereby reducing energy consumption while maintaining communication continuity through coordinated scheduling.

Inventive Principle:
Principle #23Feedback

3Use of energy by moving object

If the terminal skips reception and transmission operations during discontinuous transmission periods, then energy consumption is reduced, but communication efficiency deteriorates due to lost data transmission opportunities

Engineering Contradiction:
Improveenergy consumptionVSAvoidcommunication efficiency
Core Design Contradiction:
Use of energy by moving objectVSProductivity

Solution Approach 1:

The terminal receives preliminary indication of the discontinuous transmission configuration, allowing it to pre-plan its operations. By knowing in advance when the network entity will be inactive, the terminal can schedule critical data transmissions before the DTX period or use alternative channels, thereby avoiding energy waste while preserving communication efficiency through proactive planning.

Inventive Principle:
Principle #10Preliminary action

AI summary

There is provided an apparatus for a terminal, wherein the apparatus has means for receiving, from a network entity, an indication of a discontinuous transmission configuration associated with the network entity, wherein the indication indicates to the terminal that the network entity will refrain from providing downlink transmissions during a time period associated with the discontinuous transmission configuration. The apparatus also has means for determining whether at least one of: a reception at the terminal, and a transmission from the terminal, will at least partially overlap with the time period associated with the discontinuous transmission configuration. The apparatus also has means for, when it is determined that at least one of: the reception and the transmission will at least partially overlap with the time period, performing an action associated with the determined reception and/or transmission.
