Terminal Active Information Acquisition in Wireless Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing communication systems, terminals can only passively receive information configured by base stations and can only request channel resources, limiting the flexibility of communication.
Innovation Solution
A method where terminals actively send acquisition requests to base stations to receive specific target information, allowing them to actively acquire needed data without waiting for passive configuration, reducing time delays and enhancing flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the terminal passively receives information configured by the base station, then the communication system maintains simple control logic, but the terminal cannot actively acquire needed information and must wait for base station configuration
Solution Approach 1:
The patent inverts the traditional passive information reception model by enabling terminals to actively send acquisition requests to base stations. The terminal initiates information acquisition by constructing and transmitting request messages containing acquisition identifiers, reversing the conventional flow where the base station unilaterally provides information.
Solution Approach 2:
The patent implements a feedback mechanism where the terminal sends acquisition requests based on its needs, and the base station responds with the requested information. This feedback loop enables dynamic information acquisition tailored to terminal requirements, improving operational flexibility while maintaining manageable system complexity through structured request-response protocols.
2Loss of time
If the terminal passively waits for base station configuration, then the system maintains stable control, but time delays increase and real-time operations are hindered
Solution Approach 1:
The patent enables preliminary information acquisition by allowing terminals to send requests before actual operations are needed. The terminal can proactively acquire target information (such as channel state information or scheduling information) in advance, reducing acquisition delays and enabling real-time operations without waiting for passive configuration.
Solution Approach 2:
The request-response feedback mechanism ensures reliable information delivery while reducing delays. The terminal sends acquisition requests, receives confirmation and data from the base station, and can retransmit if necessary, maintaining communication stability while achieving faster information acquisition compared to passive waiting.
3Adaptability or versatility
If the base station configures all information unilaterally, then the control logic remains simple, but the terminal lacks flexibility in acquiring specific needed information
Solution Approach 1:
The patent extracts the information acquisition initiative from the base station and gives it to the terminal. Instead of the base station unilaterally providing all information, the terminal extracts and requests only the specific information it needs by sending acquisition requests with unique identifiers, improving adaptability while keeping the mechanism relatively simple.
Solution Approach 2:
The acquisition request mechanism serves multiple functions: it enables selective information acquisition, provides a structured way for terminals to express their information needs, and maintains compatibility with existing base station functionality. This multi-functional approach improves adaptability without proportionally increasing system complexity.
Data Source
AI summary
An information obtaining method, applicable to a terminal. The method comprises: transmitting an obtaining request to a base station, wherein the obtaining request is used for requesting the base station to transmit target information; and receiving the target information that is transmitted by the base station according to the obtaining request. The base station can not only autonomously configure information for a terminal, but can also transmit the target information to the terminal according to the obtaining request of the terminal; the terminal not only passively receives the information configured by the base station, but also can actively obtain the target information from the base station by transmitting the obtaining request to the base station.
