The White House said yesterday that President Carter still wants voluntary notification from business and labor of proposed wage and price increases, despite AFL-CIO President George Meany's statement Monday that the giant labor federation will "not cooperate."

But Carter also broadened the scope of his proposal, authorizing a statement that the administration wants to meet "soon" with labor and business leaders to explore cooperative approaches to holding down inflation.

Aides to Carter did not specify what those approaches might be. The White House press office issued a statement saying that the President "thinks it's reasonable for the federal government, in cooperation with business and labor groups, to set some goals for improving the inflationary situation and to develop - also in cooperation with business and labor - some approaches for meeting those goals."

The other approaches are being formulated by Carter's Economic Policy Group, consisting of six Cabinet officials and two of the President's top aides.

An aide to Commerce Secretary Juanita M. Kreps, one of the members, said planning is not far enough along to have specific proposals on paper, and predicted it would take a month to six weeks to finalize them.

The White House statement repeated that Carter "has no intention of imposing wage and price controls" and that he does not believe in tyring to "dictate terms of particular wage and price actions . . ."

Voluntary advance notification to the government of proposed wage and price increases is "still our objective and we certainly still wish to continue to talk and work with Mr. Meany," said deputy press secretary Rex Granum.

Although Granum said he knew of no attempts to get Carter and Meany together, Meany said in Bal Harbour, Fla., where the AFL-CIO is holding its midwinter executive council meeting, that he talked with Carter by telephone yesterday morning, but not about the advance-notification issue.

Granum also announced that Carter will meet "early next week" with Soviet dissident Vladimir Bukovsky.

Vice President Mondale was scheduled to meet with Bukovsky yesterday but post-poned the meeting because he was preparing for talks with Canadian Prime Minister Pierre Elliott Trudeau. Granum said Mondale also will meet with Bukovsky early next week, probably separately from the President.

The meeting will be Carter's second contact with a Soviet dissident. Last week he wrote to Andrei Sakharov, an action that drew a rebuke from the Soviet government.

After the President held a morning meeting yesterday with congressional leaders, assistant Senate majority leader Alan Cranston (D-Calif.) said Carter may address a joint session of Congress in April to make public his long-range energy policy.

Cranston said Carter told the group he is thinking about using the congressional forum, which would provide maximum public exposure.

The President announced yesterday that, as expected, he is nominating Mary King, his former special adviser on health and women's issues, to be the $50,000-a-year deputy director of Action, which runs the Peace Corps and VISTA programs.

King is married to Dr. Peter G. Bourne, Carter's special assistant for mental health and drug abuse.

Carter also met briefly with the nine members of his committee to select a new FBI director. After he left the room, Director Clarence M. Kelley said there is strong sentiment in the FBI to pick a new director from within, and that he would prefer that.

The President will hold his second televised news conference at 2:30 p.m. today in the Executive Office Building auditorium where he held his first one on Feb. 8.

He disclosed while taping a promotional spot for the Red Cross blood-donor drive that he is a "six-gallon donor" and will give another pint this month.
