Solution Overview

Problem

In wireless communication systems, particularly in 5G NR configurations, there is a challenge in efficiently processing paging messages across multiple schedulers connected via a non-ideal backhaul, which affects synchronization and resource allocation.

Innovation Solution

A method and apparatus for processing paging messages in a scheduled entity, involving buffering control information from a radio access network, recovering synchronization using a tracking reference signal, detecting paging control information, and processing paging data in either the paging slot or an offset slot, while performing quasi-co-located assumptions for efficient resource utilization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the scheduled entity continuously monitors and processes paging messages from multiple schedulers, then the reliability of communication is improved, but the power consumption increases

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The scheduled entity performs preliminary actions by buffering control information and performing quasi-co-located assumptions before actually processing paging messages. This allows the entity to prepare in advance and only activate full processing when necessary, reducing continuous power consumption while maintaining reliable communication monitoring

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Instead of fully processing all paging messages from multiple schedulers continuously, the scheduled entity performs partial processing by buffering control information and using quasi-co-located assumptions to selectively process only relevant paging messages. This reduces unnecessary power consumption while maintaining communication reliability

Inventive Principle:

Principle #16Partial or excessive action

2Loss of time

If the scheduled entity processes all control information immediately, then the response time is reduced, but the processing overhead increases

Engineering Contradiction:

Improveresponse timeVSAvoidprocessing overhead

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

The scheduled entity buffers control information in advance and performs preliminary processing by detecting paging control information and making quasi-co-located assumptions before full message processing. This preliminary action reduces the actual processing time when paging messages need to be handled while avoiding the overhead of immediately processing all control information

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The processing of control information is segmented into multiple stages: buffering control information, detecting paging control information, making quasi-co-located assumptions, and finally processing paging messages. This segmentation allows the entity to handle processing tasks in manageable steps, reducing overall processing overhead while maintaining responsive time

Inventive Principle:

Principle #1Segmentation

3Productivity

If the scheduled entity activates hardware components continuously, then the processing capability is improved, but the power consumption increases

Engineering Contradiction:

Improveprocessing capabilityVSAvoidpower consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The scheduled entity activates hardware components periodically rather than continuously. It buffers control information during idle periods and only activates full processing capability when paging control information is detected. This periodic activation maintains processing capability when needed while significantly reducing power consumption during non-critical periods

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The scheduled entity performs partial processing by buffering control information and using quasi-co-located assumptions to determine whether full hardware activation is necessary. This approach maintains adequate processing capability for most scenarios while avoiding excessive power consumption from continuous full-capacity operation

Inventive Principle:

Principle #16Partial or excessive action

AI summary

Extension of power efficient paging in a wireless network. In some examples, information is buffered for a time period corresponding to a paging slot, or both the paging slot and at least one adjacent slot. The buffered control information is processed to detect paging downlink control information (DCI) and a tracking reference signal (TRS). Based on the processing, the paging message is scheduled in a physical downlink shared channel (PDSCH) in the paging slot. In some examples, quasi-co-located (QCL) processing may be performed on the TRS and the paging DCI paging message, and a paging message is scheduled, based on the QCL processing, in a physical downlink shared channel (PDSCH) in a same or offset paging slot.
