Solution Overview

Problem

Wireless communication systems face inefficiencies due to excessive scheduling information overhead and limited flexibility in existing scheduling techniques, particularly in dynamic scheduling methods that do not adapt well to varying traffic types.

Innovation Solution

The implementation of hybrid scheduling techniques that combine preconfigured scheduling occasions with dynamic scheduling information, allowing user equipment (UEs) to receive initial scheduling parameters and monitor for dynamic indications to adjust scheduling accordingly, reducing unnecessary decoding and power consumption while enhancing flexibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If dynamic scheduling information is frequently transmitted to provide scheduling flexibility, then scheduling adaptability is improved, but system overhead increases

Engineering Contradiction:

Improvescheduling flexibilityVSAvoidscheduling information overhead

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The system pre-configures UEs with scheduling parameters and occasions in advance, so that scheduling decisions can be made with minimal dynamic signaling. The preconfiguration includes time-frequency resources, modulation and coding schemes, and other scheduling parameters that are prepared beforehand, reducing the need for frequent dynamic scheduling messages.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The scheduling information is segmented into preconfigured parameters and dynamic updates. Only essential dynamic information is transmitted frequently, while stable parameters are configured in advance. This segmentation allows the system to maintain scheduling flexibility without transmitting complete scheduling information repeatedly.

Inventive Principle:

Principle #1Segmentation

2Quantity of substance

If preconfigured scheduling is used to reduce overhead, then system overhead is reduced, but scheduling flexibility deteriorates

Engineering Contradiction:

Improvescheduling information overheadVSAvoidscheduling flexibility

Core Design Contradiction:

Quantity of substanceVSAdaptability or versatility

Solution Approach 1:

The system implements dynamic updates to preconfigured scheduling parameters through compact dynamic scheduling information. This allows the preconfigured scheduling to adapt to changing traffic conditions while maintaining the benefits of reduced overhead. The dynamic information enables real-time adjustments to scheduling parameters without requiring complete reconfiguration.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The preconfigured scheduling framework serves multiple functions: it provides baseline scheduling, reduces overhead for stable traffic patterns, and enables rapid adaptation through dynamic updates. This multi-functionality allows the system to operate efficiently in both static and dynamic conditions without requiring separate mechanisms.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Speed

If UEs monitor for dynamic scheduling information continuously, then scheduling responsiveness is improved, but UE power consumption increases

Engineering Contradiction:

Improvescheduling responsivenessVSAvoidUE power consumption

Core Design Contradiction:

SpeedVSUse of energy by moving object

Solution Approach 1:

UEs monitor for dynamic scheduling information at predetermined periodic intervals rather than continuously. The monitoring occasions are configured based on the scheduling periodicity and traffic patterns, allowing UEs to conserve power by entering low-power states between monitoring occasions while still maintaining scheduling responsiveness.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system configures different monitoring behaviors for different UEs and different scheduling occasions based on local conditions such as traffic type, QoS requirements, and channel conditions. This allows UEs to monitor with appropriate intensity only when necessary, reducing overall power consumption while maintaining responsiveness for time-critical scheduling.

Inventive Principle:

Principle #3Local quality

AI summary

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a hybrid scheduling configuration that includes a dynamic scheduling indication, a preconfiguration including initial scheduling parameters, and a set of preconfigured occasions for communicating data with a base station. The UE may monitor for the dynamic scheduling indication based on the initial scheduling parameters and the set of the preconfigured occasions. For instance, the UE may monitor for the dynamic scheduling indication during periodic occasions, monitor for the dynamic scheduling indication using a different periodicity, or monitor based on a time interval (e.g., a slot) during which both the preconfigured occasion and the dynamic scheduling indication occur. In any case, the UE may communicate with the base station after receiving the dynamic scheduling indication, where data may be transmitted to, or received from, the base station in accordance with the hybrid scheduling configuration.
