Grant-Free PUSCH Resource Split for UCI and UL-SCH
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication systems, the transmission performance of uplink shared channels is affected by the allocation of uplink control information on semi-statically configured physical uplink shared channels, particularly due to dynamic changes in the quantity and timing of uplink control information, which cannot be effectively managed by network devices.
Innovation Solution
A network device adjusts the resource allocation for uplink control information using an indicator in grant-free resource configuration information, allowing the terminal device to determine the appropriate resources for uplink control and shared channel transmission, ensuring optimal performance by limiting the resource usage based on predefined coefficients or indicators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal device sends uplink control information on a semi-statically configured PUSCH, then the network device cannot dynamically adjust scheduling information to meet UL-SCH transmission performance requirements, but the resource allocation for UCI dynamically changes at specific moments
Solution Approach 1:
The patent introduces a dynamic adjustment mechanism for semi-statically configured PUSCH resources by allowing the network device to send indication information that modifies the resource allocation for UCI. This enables the originally static configuration to adapt dynamically to changing transmission requirements, resolving the contradiction between static configuration and dynamic adjustment needs.
Solution Approach 2:
The patent changes the parameters of the semi-static PUSCH configuration by introducing indication information that dynamically adjusts the resource allocation for UCI within the semi-statically configured resources. This allows the network device to modify transmission parameters without changing the overall semi-static configuration structure, maintaining both stability and adaptability.
2Stability of the object's composition
If the network device uses semi-static signaling to configure PUSCH resources for multiple times, then the configuration is stable for a certain time period, but the network device cannot adjust scheduling information to meet changing UL-SCH transmission performance requirements
Solution Approach 1:
The patent transforms the purely static semi-static configuration into a dynamically adjustable structure by introducing indication information. The base configuration remains stable as before, but now includes a dynamic component that allows real-time adjustments to UCI resource allocation within the semi-statically configured PUSCH resources.
Solution Approach 2:
The patent segments the PUSCH resources into different parts: resources for UL-SCH data transmission and resources for UCI transmission. The indication information specifically adjusts the UCI resource portion, allowing independent optimization of each segment while maintaining the overall semi-static configuration structure.
3Productivity
If the terminal device allocates UCI and UL-SCH on the same PUSCH, then resource utilization is efficient, but the transmission performance of UL-SCH is affected by the quantity of resources occupied by UCI
Solution Approach 1:
The patent dynamically adjusts the resource allocation parameters for UCI within the shared PUSCH resources by using indication information. This allows the network device to optimize the balance between UCI and UL-SCH resource allocation based on current transmission conditions, maintaining efficient resource utilization while protecting UL-SCH performance.
Solution Approach 2:
The patent applies different quality requirements to different parts of the PUSCH resources: UL-SCH resources are allocated to ensure reliable data transmission, while UCI resources are dynamically adjusted based on control information requirements. The indication information enables local optimization of UCI resource allocation without compromising UL-SCH performance.

AI summary
A mobile communication uplink information transmission method and system are provided, aiming to solve a problem that when a terminal device allocates uplink control information and an uplink shared channel on a semi-statically configured physical uplink shared channel, transmission performance of the uplink shared channel is affected by a quantity of resources occupied by the uplink control information. The method is used for a terminal device to send uplink information and a network device to receive uplink information, and the terminal device receives grant-free resource configuration information, and determines a first resource used to allocate a physical uplink shared channel. The grant-free resource configuration information further includes an indicator, the indicator is used to determine a second resource, and the second resource is used to allocate uplink control information. The second resource is a part of the first resource. The terminal device further determines a third resource used to allocate an uplink shared channel. The third resource is a part of the first resource and does not intersect with the second resource, or the second resource is empty. The present invention further provides a system used for the method.
