System Information Interest Signaling for Lower Network Overhead
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems send system information to terminals regardless of their need, leading to unnecessary signaling overhead.
Innovation Solution
Terminals determine and indicate their interest in specific system information sets, and base stations send only the requested information, reducing unnecessary signaling by using interest information.

Engineering Contradiction Analysis
1Reliability
If the base station sends system information to the terminal in a broadcast manner or through dedicated signaling, then the terminal can obtain cell configuration information, but the base station increases useless signaling overhead when the terminal does not need to receive some SI
Solution Approach 1:
The terminal feeds back interest information to the base station, indicating which system information it is interested in or not interested in receiving. The base station uses this feedback to adjust its transmission behavior, sending only the system information that the terminal actually needs, thereby reducing unnecessary signaling overhead while ensuring the terminal obtains required configuration information
Solution Approach 2:
The system introduces a new parameter (interest information) that changes the transmission mode from fixed broadcast/dedicated signaling to dynamic adaptive signaling. By encoding the terminal's reception preferences into interest information, the base station can adaptively adjust which system information blocks are transmitted, optimizing the balance between information delivery and signaling efficiency

AI summary
A method for sending information includes: determining, by a terminal, a first system information set scheduled by a first cell, wherein the first system information set comprises n pieces of system information, where n is a positive integer; and sending, by the terminal, first interest information to the first cell, wherein the first interest information indicates, within the first system information set, system information that the terminal is interested in and/or not interested in receiving.
