Solution Overview

Problem

In mobile communication systems, existing methods for transmitting broadcast system information are inefficient, leading to increased power consumption and processing time for mobile terminals, especially with varying spectrum allocations, as they often receive unnecessary data and struggle to quickly acquire relevant information.

Innovation Solution

The method involves mapping different partitions of broadcast system information to shared or broadcast transport channels based on properties of the mobile terminals and the information blocks, using control information to indicate the appropriate channel for each system information block, thereby optimizing acquisition time and power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If mobile terminals receive all broadcast system information blocks on the broadcast transport channel, then complete system information is acquired, but power consumption and processing time increase due to receiving unnecessary data

Engineering Contradiction:

Improvesystem information acquisition completenessVSAvoidmobile terminal power consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent segments broadcast system information into different types (common information and dedicated information) and maps them to different transport channels. The mobile terminal only needs to receive common information blocks on the broadcast transport channel initially, while dedicated information blocks are received conditionally on shared transport channels, thus avoiding processing unnecessary data and reducing power consumption.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different transport channels are assigned different qualities or characteristics for specific purposes. The broadcast transport channel carries common information suitable for all terminals, while shared transport channels carry dedicated information for specific terminals. This local optimization allows mobile terminals to selectively receive information based on their needs, reducing overall power consumption while maintaining information completeness.

Inventive Principle:

Principle #3Local quality

2Reliability

If mobile terminals receive all broadcast system information blocks, then complete system information is acquired, but processing time increases due to handling unnecessary data

Engineering Contradiction:

Improvesystem information acquisition completenessVSAvoidinformation acquisition time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

By segmenting system information into common and dedicated blocks transmitted on different channels, the patent enables mobile terminals to quickly acquire essential common information from the broadcast transport channel without waiting for or processing all dedicated information blocks, thereby reducing overall acquisition time while maintaining completeness through conditional reception of dedicated information.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements preliminary transmission of common information blocks on the broadcast transport channel that contain essential system information needed by all mobile terminals. This allows terminals to perform preliminary acquisition of critical information immediately, while dedicated information blocks are received later on shared transport channels based on specific terminal needs, optimizing overall processing time.

Inventive Principle:

Principle #10Preliminary action

3Device complexity

If broadcast system information is transmitted on a single transport channel, then transmission simplicity is maintained, but scheduling efficiency and channel configuration flexibility are reduced

Engineering Contradiction:

Improvetransmission channel configuration simplicityVSAvoidscheduling efficiency

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

The patent makes the broadcast transport channel universal by enabling it to carry both common information blocks and, when needed, dedicated information blocks. This multi-functionality allows the system to maintain transmission simplicity using a single channel while achieving improved scheduling efficiency, as the channel can be dynamically configured to carry different types of information based on network conditions and terminal requirements.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A method and transmission apparatus transmit broadcast system information in a mobile communication system. Further, a method and mobile terminal receive the broadcast system information. An improved method for broadcasting broadcast system information maps different partitions of broadcast system information to a shared transport channel or a broadcast transport channel for transmission. The mapping may take into account parameters inherent to the mobile terminals to which the broadcast system information is to be transmitted and/or parameters inherent to the different partitions of broadcast system information.
