Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In future radio communication systems, determining the parameters for the sounding reference signal (SRS) is unclear, leading to potential deterioration in communication throughput.
Innovation Solution
A terminal and radio communication method that includes a receiving section to receive SRS configuration and a control section to determine the number of transmission combs, maximum cyclic shifts, and cyclic shift based on the SRS bandwidth, enabling appropriate SRS parameter configuration.

Engineering Contradiction Analysis
1Productivity
If the SRS parameter determination method is not clear, then the system complexity is reduced, but the communication throughput deteriorates
Solution Approach 1:
The patent applies parameter changes by dynamically determining SRS parameters (number of transmission combs, maximum number of cyclic shifts, number of cyclic shift) based on the SRS bandwidth. The control section adjusts these parameters according to the detected bandwidth, transforming fixed parameter settings into adaptive parameter selection to resolve the contradiction between system simplicity and communication throughput.
2Productivity
If the SRS parameter determination method is not clear, then the ease of operation is improved, but the communication capacity deteriorates
Solution Approach 1:
The patent implements self-service by enabling the terminal to automatically determine SRS parameters based on its own detected SRS bandwidth. The control section autonomously selects appropriate parameters without requiring complex external configuration or manual intervention, thereby maintaining ease of operation while improving communication capacity through adaptive parameter selection.

AI summary
A terminal according to one aspect of the present disclosure includes: a receiving section configured to receive a configuration related to a transmission comb of a sounding reference signal (SRS); and a control section configured to determine, based on the configuration and a bandwidth of the SRS, at least one of the number of the transmission combs, a maximum number of cyclic shifts, and a number of the cyclic shift. According to one aspect of the present disclosure, an SRS parameter can be appropriately determined.
