Wireless Communication Message Transmission Timing for Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, determining the optimal time for transmitting System Information Blocks (SIBs) and initial access information between cells is crucial for resource saving, power conservation, and minimizing latency, especially in scenarios where base stations need to conserve power and ensure continuous communication.
Innovation Solution
A method where the transmission time of messages carrying SIBs or initial access information is determined based on whether they include specific sub-information, ensuring these messages are sent at least once within a specific time length, thereby optimizing power usage and reducing interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base station transmits messages for scheduling other SIBs and initial access information continuously, then the reliability of system information transmission is improved, but the power consumption increases
Solution Approach 1:
The patent applies dynamics by making the transmission schedule adaptable rather than fixed. The base station dynamically adjusts transmission timing based on UE presence detection and power saving requirements, transitioning between active transmission and power-saving states while maintaining reliable information delivery when needed.
Solution Approach 2:
The patent implements feedback mechanisms where the base station detects UE presence and adjusts transmission behavior accordingly. This feedback loop allows the system to maintain reliability when UEs are present while reducing power consumption during periods without UEs, resolving the contradiction between continuous transmission reliability and power saving.
2Use of energy by moving object
If the base station reduces transmission frequency to save power, then power consumption is reduced, but the latency in obtaining system information increases
Solution Approach 1:
The patent applies preliminary action by having the base station transmit system information in advance during periods when UEs are detected or expected to be present. This advance transmission ensures that when UEs need the information, it is already available or can be quickly retrieved, minimizing latency while allowing reduced transmission frequency during power-saving periods.
3Reliability
If the base station transmits all system information blocks, then the completeness of information is improved, but the network resource usage increases
Solution Approach 1:
The patent applies the extraction principle by selectively transmitting only the necessary system information blocks based on UE presence and requirements. Instead of transmitting all SIBs unconditionally, the base station extracts and transmits only those information blocks that are currently needed, reducing network resource usage while maintaining information completeness for active UEs.

AI summary
The present application discloses a method and a device for wireless communications, including: receiving a first message on a first cell; transmission time of the first message depending on whether the first message comprises first sub-information; the first sub-information comprising at least one of scheduling of other System Information Blocks (SIBs) of a second cell or information required for an initial access to the second cell; herein, the phrase of transmission time of the first message depending on whether the first message comprises first sub-information comprises that: when the first message comprises the first sub-information, the first message is transmitted at least once per first time length. This application can be more power saving with indication of the first message.
