Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing wireless communication systems impose significant processing effort and power consumption on user equipment (UE) due to blind decoding of downlink control information (DCI) for resource allocation, which is inefficient and energy-intensive.

Innovation Solution

Implementing a first DCI that schedules a first set of resources for PDSCH and indicates the presence of additional scheduling information embedded within the PDSCH, allowing the UE to avoid blind decoding for subsequent DCI, thereby reducing processing effort and power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If blind decoding of DCI is performed for resource allocation, then resource allocation reliability is improved, but processing effort and power consumption increase

Engineering Contradiction:

Improveresource allocation reliabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent applies preliminary action by having the network device embed scheduling information for the second channel within the first channel's transmission resources before the UE needs to decode it. The UE receives the first DCI indicating the first channel resources, then the embedded scheduling information within those same resources provides the second channel allocation without requiring separate blind decoding operations, thus reducing power consumption while maintaining reliability

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent merges the scheduling information for the second channel into the transmission resources of the first channel. By combining both channel allocation information into a single embedded structure within the first channel's resources, the system eliminates the need for separate blind decoding operations, thereby reducing processing effort and power consumption while ensuring reliable resource allocation for both channels

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If blind decoding of DCI is performed for resource allocation, then resource allocation reliability is improved, but processing time increases

Engineering Contradiction:

Improveresource allocation reliabilityVSAvoidprocessing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The scheduling information for the second channel is prepared and embedded within the first channel's transmission resources in advance. This preliminary embedding allows the UE to obtain both channel allocation information through a single decoding process, eliminating the time loss associated with multiple separate blind decoding operations while maintaining reliable resource allocation

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

By merging the second channel scheduling information into the first channel's transmission resources, the patent enables the UE to decode both channel allocations in a single processing operation. This consolidation reduces processing time significantly compared to performing separate blind decoding for each channel, while the embedded structure ensures reliable information transmission

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If separate DCI are used for first and second channel resource allocation, then allocation flexibility is improved, but device complexity increases

Engineering Contradiction:

Improveallocation flexibilityVSAvoidUE processing complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies universality by designing the first channel transmission to serve dual purposes: carrying the first DCI for the first channel allocation and simultaneously embedding the scheduling information for the second channel. This multi-functional approach maintains allocation flexibility for both channels while reducing UE processing complexity by eliminating the need to manage and decode separate DCI structures

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent uses the nesting principle by placing the second channel scheduling information inside the first channel's transmission resources. This nested structure allows the first channel to contain within it the control information for the second channel, maintaining allocation flexibility while simplifying the UE's decoding process to a single operation rather than multiple separate operations

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

Various aspects of the present disclosure relate to receiving a first downlink control information (DCI), wherein the first DCI indicates a first resource allocation of a first set of resources for reception of a physical downlink shared channel (PDSCH), and wherein the first DCI further is indicative of a second resource allocation of a second set of resources for transmission of at least one or multiple physical uplink shared channel (PUSCH), and transmitting the at least one or multiple PUSCH using the second set of resources.
