UE SI Request Stopping via SIB1 Broadcast Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G mobile communication, user equipment (UE) experiences unnecessary power consumption and operations while waiting for a response from a base station regarding system information requests, as it continues to wait for a response even after the requested system information is determined to be broadcast, leading to inefficient resource usage.
Innovation Solution
The method involves transmitting an SI request to a base station through MSG1 or MSG3 if the SI is not being broadcast, and immediately stopping the request procedure when an updated SIB1 indicates that the SI is being broadcast, using RRC and MAC layer indications to manage random access and message reception, thereby terminating the request early.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE continues to wait for the base station response message after receiving updated SIB1 indicating the requested SI is being broadcast, then the UE ensures it receives the SI through the standard request-response procedure, but the UE experiences unnecessary power consumption and performs unnecessary operations
Solution Approach 1:
The UE performs preliminary checking by monitoring SIB1 updates during the waiting period for the base station response. When SIB1 indicates the SI is being broadcast, the UE can stop the request procedure in advance, avoiding unnecessary waiting and power consumption while ensuring SI acquisition through the broadcast channel.
2Use of energy by moving object
If the UE stops the SI request procedure early when SIB1 indicates the SI is being broadcast, then the UE reduces power consumption and avoids unnecessary operations, but the UE must carefully manage the random access procedure and message reception state
Solution Approach 1:
The UE uses SIB1 as a feedback mechanism to monitor whether the requested SI is being broadcast during the waiting period. This feedback allows the UE to make informed decisions about stopping the request procedure, balancing power savings with proper procedure management through clear state transitions.
3Loss of time
If the UE monitors for SI broadcast status during the request waiting period, then the UE can stop the request procedure early to save power, but the UE requires additional monitoring operations and state management
Solution Approach 1:
The SIB1 message serves multiple functions: it provides system information scheduling and also acts as a monitoring indicator for the SI request procedure. By leveraging this existing multi-functional message, the UE can monitor broadcast status without requiring separate dedicated monitoring channels, reducing overall system complexity.

AI summary
The present disclosure relates to a method and an apparatus for stopping an SI request, user equipment, a base station, and a computer readable storage medium. The method for stopping an SI request includes: if a first system information block (SIB1) indicates that an SI to be acquired by a UE is not being broadcast, sending an SI request to the base station by means of a first message (MSG1) or a third message (MSG3); during waiting for the base station to return an SI response, if an updated SIB1 is acquired and the updated SIB1 indicates that the requested SI is being broadcast, stopping the SI request procedure. In the embodiments of the present disclosure, the SI request can be terminated in advance, thereby reducing wasted UE power consumption and avoiding unnecessary operations.
