Wireless Access Information Transmission via Occurrence Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, terminal devices face high power consumption due to the need for long blind detection periods to obtain access information, which is broadcasted at a relatively long periodicity, leading to increased energy expenditure.
Innovation Solution
The introduction of an occurrence indication that is transmitted in association with system signatures, allowing terminal devices to determine the time point or reduced interval of subsequent access information transmission, thereby reducing detection time and energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If access information is broadcasted with long periodicity to reduce overhead, then transmission efficiency is improved, but terminal device power consumption increases due to prolonged blind detection
Solution Approach 1:
The patent introduces an occurrence indication as an intermediary element that is transmitted more frequently than the access information itself. This indication serves as a mediator that guides terminal devices to the actual access information transmission times, allowing the access information to be broadcasted with long periodicity for efficiency while the frequent occurrence indications enable terminals to quickly locate and access the information without prolonged blind detection, thus resolving the power consumption issue.
2Loss of energy
If access information is transmitted less frequently to reduce network overhead, then network resource utilization is improved, but terminal device detection time increases
Solution Approach 1:
The patent applies preliminary action by transmitting occurrence indications in advance of the actual access information. These indications are sent more frequently and provide terminal devices with advance notice of when access information will be transmitted. This allows terminals to prepare and be ready at the precise moment of information transmission, eliminating the need for prolonged blind detection and reducing detection time while maintaining reduced network overhead.
3Reliability
If blind detection period is extended to ensure access information acquisition, then information reliability is improved, but device power consumption increases
Solution Approach 1:
The patent implements a feedback mechanism where occurrence indications provide terminal devices with real-time information about upcoming access information transmissions. Terminals monitor these occurrence indications and use the feedback to adjust their detection behavior, transitioning from continuous blind detection to targeted detection at specific times indicated by the occurrence indications. This maintains reliable access information acquisition while dramatically reducing power consumption by eliminating unnecessary detection activities.

AI summary
Embodiments of the disclosure generally relate to transmission of access information. A network device generates an occurrence indication for indicating a subsequent occurrence of access information. Then, the network device transmits the occurrence indication in association with a system signature. The system signature indicates a part of the access information for use by a terminal device in accessing the network device. The power consumption of the terminal device in receiving the access information based on the occurrence indication can be reduced efficiently.
