In this more uncommon scenario, you would have your requirements outside of Jira in some other tool. You use Jira only as a testing repository for creating Tests, Test Sets, Test Plans and Test Executions.
You can use Xray for this, but you will lose the benefits of requirement coverage and traceability.
