PUCCH Resource Determination via SIB and UE ID
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in transmitting uplink channels, particularly in determining valid physical uplink control channel (PUCCH) resources without dedicated configurations, which affects the number of physical resource blocks (PRBs) and initial cyclic shift indexes, impacting communication efficiency.
Innovation Solution
A method and apparatus for determining and transmitting PUCCH resources in a wireless communication system, where the number of PRBs is based on received system information blocks (SIB), and PUCCH resources are validated by the number of PRBs, total RBs, and initial cyclic shift indexes, ensuring efficient allocation and transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If PUCCH resources are determined without dedicated configuration using a fixed set of sixteen resources, then device complexity is reduced and ease of operation is improved, but resource allocation efficiency deteriorates and productivity decreases
Solution Approach 1:
The patent makes the PUCCH resource determination dynamic by using the UE's identifier to selectively determine the number of PRBs (1 or 2) and the starting PRB index. This dynamic adaptation allows the system to optimize resource allocation based on specific UE characteristics while maintaining ease of operation through automated selection, thereby resolving the contradiction between operational simplicity and transmission efficiency.
Solution Approach 2:
The patent changes key parameters (number of PRBs and starting PRB index) based on the UE's identifier. By varying these parameters dynamically rather than using a fixed configuration, the system achieves both ease of operation (through automated parameter selection) and improved uplink transmission efficiency (through optimized resource allocation tailored to each UE).
2Device complexity
If the number of PRBs is fixed without considering UE identifier, then device complexity is reduced, but resource allocation precision deteriorates and manufacturing precision decreases
Solution Approach 1:
The patent applies local quality by tailoring the PUCCH resource allocation (number of PRBs and starting index) to each specific UE based on its identifier. Instead of a uniform fixed allocation, each UE receives locally optimized resources, improving allocation precision while keeping the overall system relatively simple through automated determination rules.
3Ease of operation
If PUCCH resources are allocated without validation based on SIB, then ease of operation is improved, but reliability deteriorates and loss of information increases
Solution Approach 1:
The patent incorporates feedback mechanisms by validating PUCCH resource allocation against system information blocks (SIB) and ensuring the determined resources fall within valid ranges. This feedback loop maintains reliability by preventing invalid allocations while preserving ease of operation through automated validation rather than manual configuration.

AI summary
A method and a device for transmitting/receiving a signal in a wireless communication system, according to one embodiment of the present disclosure, comprise the steps of: determining a physical uplink control channel (PUCCH) resource for transmitting the PUCCH; and transmitting the PUCCH through the PUCCH resource. The PUCCH resource is determined to be one of 16 PUCCH resources in a PUCCH resource set. The PUCCH resource set is a PUCCH resource set for a state in which there is no dedicated PUCCH resource configuration in a terminal. The number of physical resource blocks (PRBs) of the PUCCH resource can be determined on the basis of a received system information block (SIB).
