Premise: In an attempt to balance the interests, the Commission has decided to retain the sunset date of 2005 as the date after which licensees would not have to pay relocation costs to incumbents but decided that incumbents would not convert to secondary status until and unless an emerging technology licensee required use of the spectrum, regardless of the sunset date.

Hypothesis: The Commission will keep the 2005 sunset date and said that incumbents cannot convert to secondary status unless a specified license needed the specturm.
Relation: entailment
