Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The inefficient use of communication resources in control plane messages for interleaved physical downlink control channel control resource set 0 (PDCCH CORESET 0) leads to increased resource consumption, slower communication transfers, reduced data throughput, and congestion in open radio access networks due to the formatting of information resulting in non-integer multiple resource allocations.

Innovation Solution

Implementing a control plane section size reduction format for interleaved PDCCH CORESET 0 by configuring SE-6 and/or SE-12, and/or including a PDCCH CORESET 0 extension, to reduce the number of sections and communication resources required in control plane messages.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If traditional control plane message formatting is used for interleaved PDCCH CORESET 0, then complete resource allocation information can be transmitted, but message size increases and communication resources are wasted

Engineering Contradiction:

Improveresource allocation information completenessVSAvoidmessage resource consumption

Core Design Contradiction:

Loss of informationVSQuantity of substance

Solution Approach 1:

The patent extracts and separates the resource allocation information for interleaved PDCCH CORESET 0 from the traditional control plane message format. By identifying that CORESET 0 resource allocation has specific characteristics (interleaved pattern, known parameters), the invention extracts only the essential parameters needed to define this allocation, removing redundant information and reducing message size while maintaining complete resource allocation capability.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The invention changes the parameter representation in control plane messages by introducing a compact format specifically for CORESET 0 resource allocation. Instead of using the traditional verbose format, the patent employs optimized parameters that capture the interleaved resource allocation pattern more efficiently, thereby reducing the quantity of data transmitted while preserving all necessary resource allocation information.

Inventive Principle:

Principle #35Parameter changes

2Loss of information

If traditional control plane message formatting is used, then all resource allocation details are included, but communication latency increases

Engineering Contradiction:

Improveresource allocation detail completenessVSAvoidcommunication transfer time

Core Design Contradiction:

Loss of informationVSLoss of time

Solution Approach 1:

The patent extracts only the critical resource allocation parameters for CORESET 0 from the traditional message format, removing redundant details that do not contribute to the essential resource allocation function. This extraction reduces the total message size, thereby decreasing communication transfer time and latency while retaining all necessary resource allocation information.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The invention applies partial action by including only the essential parameters needed for CORESET 0 resource allocation in the control plane message, rather than transmitting complete traditional formatting information. This partial inclusion of parameters achieves the necessary resource allocation functionality with reduced message size and lower communication latency.

Inventive Principle:

Principle #16Partial or excessive action

3Loss of information

If traditional control plane message formatting is used for interleaved PDCCH CORESET 0, then comprehensive resource allocation is achieved, but network congestion increases

Engineering Contradiction:

Improveresource allocation comprehensivenessVSAvoidnetwork throughput

Core Design Contradiction:

Loss of informationVSProductivity

Solution Approach 1:

The patent extracts and transmits only the essential resource allocation parameters for interleaved PDCCH CORESET 0, removing redundant information from the traditional message format. This extraction reduces the overall message size, allowing more messages to be transmitted through the network simultaneously, thereby reducing congestion and improving network throughput while maintaining comprehensive resource allocation capability.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The invention changes the parameter structure in control plane messages to a more compact representation suitable for interleaved PDCCH CORESET 0 resource allocation. This parameter optimization reduces the data volume transmitted across the network, decreasing network load and congestion while preserving complete and comprehensive resource allocation information.

Inventive Principle:

Principle #35Parameter changes

AI summary

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a distributed unit (DU) may receive an indication that a radio unit (RU) supports a control plane (C-Plane) section size reduction format. The DU may transmit, based at least in part on receiving the indication, a C-Plane message that uses the C-Plane section size reduction format, the C-Plane message indicating a resource allocation for an interleaved physical downlink control channel (PDCCH) control resource set (CORESET) 0. Numerous other aspects are described.
