President Carter met with two more groups of Camp David yesterday as his "domestic summit conference" neared its end and he prepared to report to the American people.

White House press secretary Jody Powell said Carter will remain at the presidential retreat, probably at least until tomorrow, studying various options for dealing with the energy shortage and its economic consequences.

White House officials made no announcement of the president's plans beyond that, but there were strong indications Carter will make a nationally televised speech Sunday night.

Carter conferred yesterday afternoon with more than a dozen businnessmen, labor and civil rights leaders and members of Congress on the economy, particularly the likely rise in unemployment from the recession the administration is forecasting. Last night, he summoned a group of mayors to Camp David for another discussion of economic policy.

Yesterday's meetings apparently marked the end of the steady stream of visitors called to Camp David to discuss domestic policy since the summit began last week. Powell said that for the next two days at least, Carter will concentrate on various staff recommendations, primarily on energy policy.

United Press international, quoting an unnamed White House side, said yesterday that Energy Secretary James R. Schlesinger Jr. is going to resign because he has become a "political liability."

Powell called the report "uninformed speculation," but did not deny it. He noted that twice before Schlesinger has offered to resign but has remained at his post "at the president's insistence."

Schlesinger has been criticized in Congress and by some members of the White House staff who have made no secret of their desire to see him tired. But he has to date had Carter's strong backing.

As of yesterday, Schlesinger had not renewed his resignation offer to Carter, it was learned. But White House officials were unable to say what Carter would do if Schlesinger does again offer his resignation.

Powell said yeaterday's meetings focused on youth unemployment. He said Carter reported he will soon confer with excutives from major corporations on how private industry can ease the problem of youth unemployment.

Jerry Wurf. president of the American Federation of State, County and Municipal Employes and one of those who met with the president yesterday, said Carter "didn't tell us an awful lot."

"He said he would do hard things," Wurf said. "He said he had a sensitivity to the problems that worry us. He said he wanted to listen and make judgments." CAPTION: Picture, JODY POWELL . . . calls speculation "uninformed"
