Disclosed is a method for utilizing SCH resources more efficiently for supplemental channels (SCH) by minimizing gaps between data bursts due to overhead delays. Such gaps are minimized using a supplemental channel sharing algorithm to prospectively assign SCH resources supporting existing SCHs and to schedule future issuance of DNRs such that currently unavailable SCH resources may be prospectively assigned based on states of the SCH resources, wherein an existing SCH is a SCH over which a data burst is currently being transmitted.
