Solution Overview

Problem

Wireless communications systems face challenges in effectively handling interactions between cell discontinuous communications (e.g., DTX/DRX cycles) and measurement occasions, leading to interruptions and unclear UE behavior during overlapping time periods.

Innovation Solution

Implementing rules for prioritization or adjustment of cell DTX/DRX communications and radio measurements based on overlapping time periods, allowing dynamic handling of measurement occasions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If measurement occasions are scheduled during active communication time periods in cell discontinuous communications, then measurement accuracy is improved, but communication latency increases and power consumption rises

Engineering Contradiction:

Improvereference signal measurement accuracyVSAvoidcommunication latency

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The measurement occasion is segmented into two distinct parts: a first part during the active time period for communication, and a second part during the inactive time period for measurement. This segmentation allows the UE to perform reference signal measurements without interrupting ongoing communications, thereby resolving the contradiction between measurement accuracy and communication latency.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The UE performs reference signal measurements during the inactive time period before the active communication period begins. By conducting measurements in advance during the second time period, the UE prepares measurement results before communication starts, eliminating the need to interrupt communication for measurements and thus reducing latency.

Inventive Principle:

Principle #10Preliminary action

2Measurement precision

If measurement occasions are scheduled during active communication time periods, then measurement precision is improved, but power consumption increases

Engineering Contradiction:

Improvereference signal measurement accuracyVSAvoidUE power consumption

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The measurement occasion is divided into a first part during active communication and a second part during inactive period. The UE performs power-intensive reference signal measurements during the inactive time period when communication is not occurring, thereby achieving accurate measurements without consuming additional power during active communication periods.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The UE maintains continuous operation during active communication periods without interrupting for measurements. By scheduling measurements during inactive periods, the UE ensures continuous communication activity while still performing necessary measurements, thereby optimizing power usage while maintaining measurement precision.

Inventive Principle:

Principle #20Continuity of useful action

3Use of energy by moving object

If measurement occasions overlap with inactive time periods, then power consumption is reduced, but measurement reliability deteriorates

Engineering Contradiction:

ImproveUE power consumptionVSAvoidmeasurement reliability

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

The measurement occasion is segmented such that the critical reference signal measurement component occurs during the inactive time period when power consumption is reduced, while a first part during the active period ensures proper timing and synchronization. This segmentation allows measurements to be performed during low-power periods while maintaining reliability through the structured two-part approach.

Inventive Principle:

Principle #1Segmentation

AI summary

Certain aspects of the present disclosure provide techniques for interaction between cell discontinuous communications and measurement occasions. An example method for wireless communications by an apparatus includes obtaining a first configuration for cell discontinuous communications, wherein the first configuration indicates (i) a first time period during which communication via a first cell is allowed and (ii) a second time period during which communication via the first cell is unavailable; obtaining a second configuration that indicates one or more measurement occasions for reference signal measurement; obtaining an indication of one or more rules for reference signal measurement during a measurement occasion that overlaps in time with a time period during which communication via the first cell is allowed; and communicating with a network entity based on the first configuration, the second configuration, and the one or more rules.
