Narrative:

On arrival...; ATC assigned 5;000 feet & and slow to 160 kts. Our next clearence was to maintain 5;000 feet until [fix] cleared ILS 36L. The first officer was still a low time first officer and wanted to slow to landing configuration on schedule; so we did. After contacting tower; they asked our speed and we replied we were at our vref. They said we were supposed to fly last assigned speed. So we sped up to 160 kts. However we were cleared for the approach and neither of us recalled a speed restriction nor did I recall reading back one to ATC. Tower turned us off the approach and we were vectored around to try it again. No further issues were encountered.
