Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for wireless data traffic in 4G and the need for supporting various vertical applications necessitates improvements in radio interface efficiency and coverage, which 5G communication systems aim to address through technologies like massive antenna systems and new waveforms, but there is a challenge in efficiently transmitting and receiving system information in these advanced networks.
Innovation Solution
A user equipment (UE) and base station (BS) are equipped with a transceiver and processor to receive and transmit configuration information for system information blocks (SIBs) using reference and delta configurations, allowing for efficient acquisition of full SIB configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If full SIB configuration is transmitted repeatedly, then system information reliability is improved, but radio interface efficiency deteriorates due to redundant transmission
Solution Approach 1:
The SIB configuration is segmented into two parts: a reference configuration that is transmitted periodically for reliability, and a delta configuration that contains only the changes. This segmentation allows the system to maintain reliability through periodic transmission while improving efficiency by only transmitting changes in the delta part.
Solution Approach 2:
The invention extracts only the changed portions of the SIB configuration into a separate delta configuration message. Instead of transmitting the entire SIB configuration repeatedly, only the differential changes are extracted and transmitted, significantly reducing redundant data transmission while maintaining information completeness.
2Productivity
If delta configuration is used to reduce transmission overhead, then radio interface efficiency is improved, but UE processing complexity increases
Solution Approach 1:
The UE is pre-provided with the reference SIB configuration through system information broadcast or pre-configuration. This preliminary action enables the UE to have the baseline configuration already stored, so when receiving the delta configuration, it only needs to apply the differences rather than processing complete configuration messages, thus reducing processing complexity.
3Productivity
If reference configuration is provided separately, then configuration update efficiency is improved, but information transmission overhead increases
Solution Approach 1:
The invention merges the reference configuration transmission with existing system information broadcast mechanisms. The reference configuration is provided through existing SI message structures, and the delta configuration is transmitted using the same broadcast channels, thereby avoiding additional overhead while maintaining the benefits of differential updates.

AI summary
A user equipment (UE) includes a transceiver configured to receive, from a wireless network, at least one message including configuration information for a system information block (SIB). The UE also includes a processor operably coupled to the transceiver. The processor is configured to obtain a reference configuration of the SIB, obtain a delta configuration of the SIB, and determine a full configuration of the SIB based on a combination of the reference configuration and the delta configuration. At least one of the reference configuration of the SIB and the delta configuration of the SIB are obtained based on the at least one message including the configuration information for the SIB.
