Find Innovative SolutionsGenerate Solutions
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 sleep periods and adjusting behaviors to avoid collisions, including skipping or postponing operations during these periods.

Engineering Contradiction Analysis
1Loss of energy
If the network entity uses discontinuous transmission configuration to save energy, then energy consumption is reduced, but transmission reliability deteriorates due to potential overlaps with terminal reception/transmission periods
Solution Approach 1:
The network entity provides advance indication of the discontinuous transmission configuration to the terminal before the actual transmission occurs. This allows the terminal to prepare for potential overlaps by determining in advance whether its scheduled reception or transmission will conflict with the network's DTX period, enabling proactive adjustment of operations to maintain reliability while preserving energy savings.
Solution Approach 2:
The terminal feeds back information about its scheduled reception and transmission operations to the network entity. Based on this feedback, the network entity can determine whether overlaps will occur and adjust its discontinuous transmission configuration accordingly, ensuring that energy savings do not compromise transmission reliability through collaborative optimization.
2Stability of the object's composition
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
Solution Approach 1:
The terminal uses the advance indication of the discontinuous transmission configuration to determine beforehand whether its scheduled operations will overlap with the network's DTX period. If no overlap is detected, the terminal can skip unnecessary reception and transmission operations, thereby reducing energy consumption while maintaining communication continuity when needed.
Solution Approach 2:
The terminal dynamically adjusts its operation schedule based on the network's discontinuous transmission configuration. By flexibly modifying when and how it performs reception and transmission operations according to the provided indication, the terminal optimizes energy consumption while ensuring communication continuity is maintained during critical periods.

AI summary
There is provided an apparatus for a terminal, wherein the apparatus has circuitry 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 period time associated with the discontinuous transmission configuration. The apparatus also has circuitry for determining whether at least one of: a reception at the terminal, or a transmission from the terminal, will at least partially overlap with the time period associated with the discontinuous transmission configuration. The apparatus also has circuitry 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.
