Solution Overview

Problem

Existing wireless communication systems face low transmission efficiency of control information and data information due to the lack of effective solutions for multiplexing and encoding CSI, HARQ-ACK, and SR information.

Innovation Solution

The method involves transmitting and receiving at least two pieces of information, including CSI, HARQ-ACK, and SR, in a multiplexing manner on a physical channel, using joint or separate encoding techniques to optimize transmission efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If CSI and control information are transmitted separately using existing encoding modes, then the transmission can be performed with simple encoding, but the transmission efficiency is low

Engineering Contradiction:
Improvetransmission efficiencyVSAvoidencoding complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent combines CSI and control information (HARQ-ACK and/or SR) into a single multiplexed transmission on the physical uplink shared channel. The terminal performs joint encoding of both CSI and control information, treating them as a unified data stream rather than separate transmissions. This merging approach increases transmission efficiency by utilizing resource elements more effectively while the encoding complexity is managed through standardized joint encoding procedures.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If CSI report is divided into two parts for separate encoding, then encoding can be simplified, but there is no effective solution for multiplexing with control information

Engineering Contradiction:
Improvemultiplexing capabilityVSAvoidencoding complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent enables the physical uplink shared channel to serve multiple functions simultaneously: transmitting both CSI and control information (HARQ-ACK and/or SR) through multiplexing. The joint encoding mechanism allows the channel to handle diverse information types in a unified manner, providing versatility in handling different uplink transmission requirements while maintaining manageable encoding complexity through standardized procedures.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Productivity

If all CSI parameters are encoded together in a single mode, then encoding is straightforward, but transmission efficiency remains low when multiplexing with control information

Engineering Contradiction:
Improvetransmission efficiencyVSAvoidencoding operation
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent merges CSI and control information into a single multiplexed transmission stream on the physical uplink shared channel. The terminal performs joint encoding that treats both CSI and control information as part of the same data stream, enabling efficient utilization of available resource elements. This approach improves transmission efficiency by eliminating the need for separate transmission channels while the encoding operation remains manageable through standardized joint encoding procedures.
