PUSCH PUCCH Simultaneous Transmission Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently configuring and reporting uplink control information, particularly in simultaneous transmission scenarios, which affects the performance and reliability of 5G mobile communication systems.
Innovation Solution
The proposed solution involves a method where a user equipment (UE) transmits UE capability information for simultaneous transmission of a physical uplink shared channel (PUSCH) and a physical uplink control channel (PUCCH) to a base station. The base station then configures and receives the PUSCH and PUCCH transmissions based on this information, ensuring that the PUSCH is excluded from resolving time overlapping with the PUCCH.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the PUSCH and PUCCH transmissions are configured to resolve time overlapping, then the reliability of control information transmission is improved, but the simultaneous transmission capability and efficiency are degraded
Solution Approach 1:
The patent extracts the PUSCH from the time overlapping resolution process by excluding it from the resolving mechanism. This allows the PUCCH to maintain its transmission integrity while the PUSCH is handled separately, enabling simultaneous transmission without compromising control information reliability.
Solution Approach 2:
The patent segments the transmission handling by applying different rules to PUSCH and PUCCH. The PUCCH follows traditional time overlapping resolution while the PUSCH is excluded from this process, allowing independent optimization of each channel's transmission characteristics.
2Productivity
If the PUSCH is included in resolving time overlapping with PUCCH, then the resource allocation efficiency is improved, but the simultaneous transmission of PUSCH and PUCCH is prevented
Solution Approach 1:
The PUSCH is extracted from the time overlapping resolution framework, creating a separate handling path. This extraction enables the system to maintain high resource allocation efficiency for PUCCH while simultaneously supporting PUSCH transmission without conflict.
Solution Approach 2:
The patent introduces dynamic configuration information that allows the base station to flexibly control whether PUSCH is excluded from time overlapping resolution. This dynamic adaptability enables the system to switch between different transmission modes based on current network conditions and service requirements.
3Device complexity
If configuration information for simultaneous transmission is not provided, then the system complexity is reduced, but the simultaneous transmission performance is degraded
Solution Approach 1:
The base station performs preliminary configuration by providing configuration information to the UE before simultaneous transmission occurs. This advance configuration establishes the exclusion rule for PUSCH, ensuring that when simultaneous transmission is needed, the UE is already prepared with the correct transmission parameters.
Solution Approach 2:
The system implements feedback through the configuration information exchange between base station and UE. The base station determines the appropriate configuration based on network conditions and UE capabilities, then provides this configuration to the UE, which feeds back its capability information, creating a closed-loop control system that optimizes simultaneous transmission performance.
