Solution Overview

Problem

Existing wireless communication systems face challenges in efficiently performing wireless signal transmission and reception, particularly in managing uplink control information and HARQ-ACK information.

Innovation Solution

A method and apparatus for a user equipment (UE) in a wireless communication system, involving the reception of resource allocation information for a configured grant (CG)-based uplink transmission, configuration information for multiplexing between CG uplink control information (UCI) and HARQ-ACK information, joint encoding of the CG UCI and HARQ-ACK information, and transmission of a CG physical uplink shared channel (PUSCH) based on the resource allocation information, with a beta offset value applied to the joint encoding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If separate transmission of CG UCI and HARQ-ACK information is used, then transmission reliability is maintained, but transmission efficiency deteriorates due to increased signaling overhead and resource consumption

Engineering Contradiction:
Improvetransmission efficiencyVSAvoidsignaling overhead
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The patent combines CG UCI and HARQ-ACK information into a single joint encoded transmission on PUSCH. This merging eliminates the need for separate PUCCH resources for CG UCI, reduces signaling overhead, and improves transmission efficiency by consolidating control information into one channel while maintaining reliable delivery of both information types

Inventive Principle:
Principle #5Merging (Combining)

2Productivity

If joint encoding of CG UCI and HARQ-ACK information is performed, then resource allocation efficiency is improved, but encoding complexity increases

Engineering Contradiction:
Improveresource allocation efficiencyVSAvoidencoding complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent introduces beta offset values (beta_offset_UCI, beta_offset_HARQ-ACK, beta_offset_joint) as configurable parameters that control resource allocation and power distribution in joint encoding. These parameter changes enable flexible adjustment of encoding weights and resource distribution, allowing the system to optimize performance while managing encoding complexity through standardized parameter sets

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If beta offset values are configured for different payload size ranges, then transmission adaptability is improved, but configuration complexity increases

Engineering Contradiction:
Improvetransmission adaptabilityVSAvoidconfiguration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the payload size configuration into three distinct ranges with specific beta offset values. This segmentation allows the system to adapt transmission parameters based on payload size conditions while maintaining manageable configuration complexity through clear range definitions and standardized value assignments for different payload scenarios

Inventive Principle:
Principle #1Segmentation

AI summary

A method of a user equipment (UE) in a wireless communication system includes receiving resource allocation information related to a configured grant (CG)-based uplink transmission, receiving configuration information indicating multiplexing between CG uplink control information (CG UCI) and hybrid automatic repeat request acknowledgement (HARQ-ACK) information, performing joint encoding of the CG UCI and the HARQ-ACK information based on the configuration information, and transmitting a CG physical uplink shared channel (CG PUSCH) based on the resource allocation information. The joint-encoded information is multiplexed in the CG PUSCH. A beta offset value corresponding to one of a first index, a second index, or a third index related to a beta offset for the HARQ-ACK information is applied to the joint encoding.
