Solution Overview

Problem

The existing New Radio (NR) systems face challenges in efficiently handling downlink control and data channels with different numerologies, leading to increased receiver complexity and power consumption due to the need for decoding multiple numerologies in the same symbol.

Innovation Solution

The proposed solution involves mechanisms for handling control resource sets with different numerologies, including configuring the same numerology for all control resource sets based on UE capability, using time division multiplexing for multiple control resource sets, and inserting guard bands between control and data channels with different numerologies, to reduce receiver complexity and power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple numerologies are used for control and data channels in the same symbol, then system flexibility and service diversity are improved, but receiver complexity and power consumption increase

Engineering Contradiction:

Improveservice diversityVSAvoidreceiver complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments control resource sets into different groups, where each group is associated with a specific numerology. This segmentation allows the receiver to process control channels with different numerologies separately, reducing the complexity of simultaneously handling multiple numerologies in the same symbol while maintaining service diversity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a new dimension of control resource set grouping based on numerology association. By organizing control resource sets into groups with specific numerology characteristics, the system adds a structural dimension that simplifies receiver processing without limiting the use of multiple numerologies for different services.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If multiple numerologies are decoded in the same symbol, then channel flexibility is improved, but power consumption increases

Engineering Contradiction:

Improvechannel flexibilityVSAvoidpower consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

By segmenting control resource sets into numerology-specific groups, the receiver can selectively process only the relevant group based on the numerology configured for control channels. This reduces the overall processing load and power consumption compared to decoding all possible numerologies in the same symbol.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary organization of control resource sets into groups before actual decoding occurs. This preliminary action of grouping allows the receiver to quickly identify and process only the relevant control resource sets, avoiding unnecessary power consumption from processing irrelevant numerologies.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If control resource sets use different numerologies, then service adaptability is improved, but decoding complexity increases

Engineering Contradiction:

Improveservice adaptabilityVSAvoiddecoding complexity

Core Design Contradiction:

Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent segments control resource sets into distinct groups, where each group is associated with a specific numerology. This segmentation simplifies the decoding process by allowing the receiver to focus on one numerology group at a time, reducing the overall decoding complexity while maintaining service adaptability across different numerologies.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by associating specific numerology characteristics with specific control resource set groups. This allows different parts of the control channel structure to have optimized properties for their intended numerology, making decoding easier while maintaining adaptability to different service requirements.

Inventive Principle:

Principle #3Local quality

AI summary

Techniques discussed herein can facilitate handling of DL (Downlink) control and data channels having different numerologies in NR (New Radio). One example embodiment comprises an apparatus employable by a UE (User Equipment) configured to generate a report comprising capability information associated with the UE, wherein the capability information indicates whether the UE supports multiplexing of multiple numerologies within a common symbol in a FDM (Frequency Division Multiplexing)-based manner; process first higher layer signaling that configures one or more control resource sets of a NR (New Radio) PDCCH (Physical Downlink Control Channel), wherein the one or more control resource sets are associated with one or more numerologies in accordance with the UE capability information; and demodulate a NR PDSCH (Physical Downlink Shared Channel) from a resource distinct from resources of the NR PDCCH.
