The present invention provides a wireless communication method supporting hybrid automatic repeat request. The method includes: sending first hybrid automatic repeat request (HARQ) process quantity indication information to a user equipment UE; and if second HARQ process quantity indication information is further sent to the UE, determining a second HARQ process quantity according to the second HARQ process quantity indication information, and performing data transmission with the UE according to the determined second HARQ process quantity. Correspondingly, the present invention further provides a base station and the user equipment. In the present invention, the base station and the user equipment can perform data communication with the UE based on different HARQ timing relationships and HARQ process quantities, thereby being capable of better supporting UEs adopting different functional characteristics.
