The Federal Communications Commission has put off until next year consideration of a proposal to drop its regulation of long-distance telephone profits in favor of ceilings on rate increases, an aide to Chairman Dennis R. Patrick said.

Patrick had been working toward a vote on the plan next month, but a consensus with other commissioners has eluded him."There are so many complex issues and a long draft order, we wanted to give commissioners an additional opportunity to study the issues and consider it in January," said the aide, James Schlichting.

That meeting is scheduled for Jan. 19.

The decision to delay consideration of the proposal also recognizes opposition in Congress, he said. Key members have said the already bad relations between Congress and the FCC will be worsened considerably if the agency adopts the proposal before lawmakers return to Capitol Hill in early January.
