PUCCH Resource Inference for Wireless Control Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in transmitting control information, particularly in resource allocation for physical uplink control channels (PUCCHs), which limits the system's ability to manage increased control information effectively.
Innovation Solution
A method for simultaneously transmitting multiple PUCCHs by recognizing resources for a first PUCCH and inferring resources for additional PUCCHs, allowing them to be transmitted through corresponding resources, including the use of higher layer signaling and mathematical equations to determine resource indices.

Engineering Contradiction Analysis
1Productivity
If multiple PUCCH resources are allocated for simultaneous transmission, then control information transmission capability is improved, but resource allocation complexity increases
Solution Approach 1:
The UE autonomously infers the second PUCCH resource index from the first PUCCH resource index using a predetermined formula, eliminating the need for explicit network configuration of multiple resources. The system serves itself by deriving additional resources from existing ones through mathematical relationships.
Solution Approach 2:
The patent transforms the resource allocation approach by changing from explicit configuration of multiple independent parameters to deriving parameters through mathematical relationships. The second PUCCH resource index is obtained by applying an offset to the first resource index, converting a complex multi-parameter configuration into a simplified single-parameter derivation.
2Quantity of substance
If multiple PUCCHs are transmitted simultaneously, then control information coverage is improved, but inter-modulation distortion increases
Solution Approach 1:
The patent applies different resource allocation strategies to different PUCCH instances. By carefully selecting and offsetting resource indices for the first and second PUCCHs, the system ensures that simultaneous transmissions use locally optimized resources that minimize interference, rather than using uniform resource allocation.
3Reliability
If PUCCH resources are explicitly configured, then transmission reliability is improved, but signaling overhead increases
Solution Approach 1:
The patent extracts the essential configuration information (first PUCCH resource index) and uses it to derive the second PUCCH resource index through a predetermined formula. This removes the need to explicitly configure and transmit separate configuration data for the second resource, eliminating redundant signaling while maintaining reliable resource allocation.

AI summary
The present invention relates to a wireless communication system. More particularly, the present invention relates to a method and apparatus for transmitting a plurality of PUCCHs in a wireless communication system, wherein the method comprises the following steps: checking a resource for a first PUCCH among the plurality of PUCCHs; inferring, from the resource for the first PUCCH, a resource for the remaining one or more second PUCCHs excluding the first PUCCH among the plurality of PUCCHs; and transmitting the plurality of PUCCHs simultaneously via corresponding relevant resources.
