Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing energy saving signal transmission methods in 5G NR struggle to effectively configure the quantity of DRX cycles, leading to inefficiencies in energy saving, increased transmission delay, and reduced terminal performance, especially when dealing with varying DRX cycle lengths.
Innovation Solution
The proposed method involves configuring an energy saving signal that carries information to indicate a first configuration of at least one DRX cycle, including a maximum quantity of DRX cycles, a maximum quantity of first cycles, or a specific quantity of first cycles, allowing for flexible indication of DRX cycles with different lengths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If an energy saving signal indicates a next DRX cycle with a fixed configuration, then the terminal can skip invalid PDCCH monitoring to reduce power consumption, but the transmission delay increases and terminal performance deteriorates when the DRX cycle is relatively long
Solution Approach 1:
The patent applies dynamics by making the DRX cycle configuration flexible and adaptable. The base station can dynamically adjust the DRX cycle length and configuration based on terminal behavior and network conditions. The energy saving signal can indicate different DRX cycle configurations (short or long) depending on the situation, allowing the system to transition between different operational states rather than being fixed.
Solution Approach 2:
The patent changes the parameter of DRX cycle configuration from a fixed value to a variable that can be adjusted. The energy saving signal carries information about DRX cycle parameters (such as cycle length, activation timing) that can be modified based on terminal performance requirements. This allows optimization of both power consumption and transmission delay by selecting appropriate parameter values.
2Productivity
If the energy saving signal is sent frequently to indicate short DRX cycles, then terminal energy saving effect is poor, but if sent less frequently for long DRX cycles, then transmission delay increases
Solution Approach 1:
The system dynamically selects between short and long DRX cycle configurations based on current network conditions and terminal state. The energy saving signal indicates which configuration should be used, allowing the terminal to adapt its monitoring behavior. This dynamic adjustment optimizes the balance between energy saving efficiency and response time.
Solution Approach 2:
The patent employs periodic action through DRX cycles, where the terminal alternates between active monitoring periods and sleep periods. The energy saving signal controls the timing and duration of these periodic actions. By adjusting the periodicity (short vs long cycles), the system can balance between frequent updates (better responsiveness) and less frequent updates (better energy saving).
3Adaptability or versatility
If the energy saving signal indicates multiple DRX cycles, then the coverage of energy saving effect is improved, but the complexity of configuration increases
Solution Approach 1:
The patent segments the DRX cycle configuration into multiple indicable cycles within the energy saving signal. Instead of indicating a single DRX cycle, the signal can specify multiple cycles with different parameters. This segmentation allows the system to provide comprehensive energy saving coverage across different time periods and conditions while keeping each individual cycle configuration manageable.
Solution Approach 2:
The energy saving signal is designed with multi-functionality, capable of indicating multiple different DRX cycle configurations in a single signal transmission. This universal indication mechanism can cover various scenarios (different cycle lengths, different activation patterns) without requiring separate signals for each case, thereby improving energy saving coverage while controlling configuration complexity.

AI summary
Disclosed are an energy conservation transmission method, base station, and terminal device; the base station can configure an energy conservation signal for the terminal device; the energy conservation signal carries energy conservation information; the energy conservation information can indicate a first configuration of at least one discontinuous reception (DRX) cycle of the terminal device, the at least one DRX cycle comprising at least one first cycle and/or at least one second cycle; the first cycle and the second cycle are long cycles and/or short cycles, and the first cycle is different from the second cycle; the first configuration of the DRX cycle includes at least one of the maximum number N of DRX cycles, the maximum number K of the first cycle, and the number Y of the first cycle, all of N, K, and Y being integers greater than or equal to 1; thus the energy conservation signal can indicate to the terminal device for any combination of DRX cycles of different lengths, solving the problem in the prior art of how to configure the number of DRX cycles indicated by the energy conservation signal.
