Solution Overview

Problem

In wireless communication systems, the existing paging processes lead to increased power consumption and resource inefficiency in mobile stations (MS) due to the need for all MSs to decode paging signals, even if only a specific MS is targeted, which affects both idle mode operation and resource allocation.

Innovation Solution

The proposed method involves a base station (BS) transmitting a paging indicator through synchronization or control channels, allowing only targeted MSs to receive and decode paging messages, thereby reducing unnecessary decoding and resource allocation, and utilizing coverage classes to optimize resource usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If all MSs decode both first and second paging signals, then paging coverage is ensured, but power consumption of MS increases

Engineering Contradiction:
Improvepaging coverageVSAvoidpower consumption of MS
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The paging signal is segmented into two parts: a first paging signal transmitted on a scheduling channel that all MSs decode, and a second paging signal transmitted on a data channel that only specific target MSs decode. This segmentation allows MSs to quickly determine if they are the target of paging without always decoding both signals, thereby reducing power consumption while maintaining reliable paging coverage.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The first paging signal is transmitted preliminarily before the second paging signal. This preliminary action allows MSs to check if paging is intended for them before committing resources to decode the second paging signal, reducing unnecessary power consumption for MSs that are not the paging target.

Inventive Principle:
Principle #10Preliminary action

2Use of energy by moving object

If paging group ID is allocated for each paging group, then power consumption of MS is reduced, but resource efficiency decreases

Engineering Contradiction:
Improvepower consumption of MSVSAvoidresource efficiency
Core Design Contradiction:
Use of energy by moving objectVSProductivity

Solution Approach 1:

Instead of allocating unique paging group IDs to all MSs, the system applies local quality by allocating paging group IDs only to MSs that are actual paging targets or belong to relevant paging groups. This selective allocation reduces the number of resources consumed for paging group ID management while still enabling MSs to efficiently determine whether they need to decode paging messages.

Inventive Principle:
Principle #3Local quality

AI summary

The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as a long term evolution (LTE). A method for performing a paging process by a base station (BS) in a wireless communication system is provided. The method includes identifying that paging for a mobile station (MS) is initiated, and transmitting a paging indicator including a first part indicating a paging identifier (ID) and a second part indicating a group in which at least one MS which needs to receive a paging message is included.
