President Carter yesterday nominated Charles D. Ferris, 44, to the Federal Communications Commission for a full seven-year term. Ferris also was designated as chairman, to succeed Richard E. Wiley, whose term has expired.

Meanwhile, Washington attorney Tyrone Brown disclosed yesterday that he had withdrawn his name from consideration for the FCC seat formerly held by Benjamin Hooks, for a term that has 21 months left to run.

Brown, considered to be the leading candidate for the Hooks position, declined to comment on his withdrawal.

Barry Jogoda, special assistant to the President for media and public affairs, said yesterday, "I have nothing to say about the other vacancy on the FCC except that it is a matter of importance to the President and is being dealt with in as timely a fashion as possible.

There has been considerable speculation that several black groups, including the congressional Black Caucus, has been pressing for a black nominee for the full seven-year term that went to Ferris. But whether Brown's withdrawal reflected agreement with that position could not be learned.

A spokesmen for the Senate Commerce Committee said, yesterday that Communications Subcommittee chairman Ernest K. Hollings (D-S.C.) was out of town and that no date for hearings on Ferris' nomination had been set.

Ferris has been general counsel to House Speaker Thomas P. O'Neill (D-Mass.) since early this year. For 13 years before that he was senior aide to then Senate Majority Leader Mike Mansfield and general counsel to the Senate Democratic Policy Committee. He is a 1954 graduate of Boston College.

Approval of his nomination is considerate a certainty.
