The invention discloses a transmission method combining AP (Access Point) selection and pilot frequency distribution, which is characterized in that pilot frequency pollution is reduced to obtain a pilot frequency distribution scheme by reducing the pilot frequency multiplexing condition in the same area, AP selection and pilot frequency distribution schemes are combined, and an optimal pilot frequency distribution and AP selection combined scheme is output in an iteration mode. Aiming at the pilot frequency distribution problem, the invention aims to reduce the pilot frequency pollution, and the pilot frequency pollution of the whole system is reduced based on the grouping and sorting pilot frequency distribution algorithm of the channel and the geographic position. Aiming at the AP selection problem, under the condition that a certain rate requirement of a user is met, the power distribution value is obtained by taking the minimization of the total power consumption of the system as a target, and the servic
