Abstract: The present invention discloses a pilot allocation method and apparatus, and relates to the field of wireless communications technologies, so as to resolve a problem that relatively strong pilot interference is generated between users on which MUBF pairing is performed. In the embodiments of the present invention, a base station determines user equipments UEs requiring multi-user beam forming MUBF pairing and to-be-allocated ports, sets a quantity of orthogonal cover codes OCCs according to a quantity of the to-be-allocated ports, and determines a pilot allocation result according to the quantity of the to-be-allocated ports, the quantity of the OCCs, and a quantity of the UEs. The solutions provided in the embodiments of the present invention are applicable to pilot allocation.
