Qualification
An NOC may enter up to one men's team with 12 players and up to one women's team with 12 players. Automatic qualifications were granted to the host country for both events, plus the winning team at the 1978 FIBA World Championship and the Olympic champions in the men's tournament. The remaining spots were decided by corresponding continental qualifying championships for the men's competition, and in a tournament held months before the Olympic Games in Varna, Bulgaria for the women's event.
