主权项 1. A signal transmission method, comprising: setting K virtual users, wherein each of the virtual users is associated with one base station; obtaining base station precode and user precode corresponding to each of the K virtual users; splitting a baseband signal to the K virtual users, and obtaining a split baseband signal corresponding to each of the K virtual users; processing, according to the base station precode and the user precode corresponding to each of the virtual users, the split baseband signal corresponding to each of the virtual users, and obtaining an uplink signal corresponding to each virtual user; and obtaining timing advances {t1, t2, . . . , tK} of base stations corresponding to the K virtual users, and when max(t1, t2, . . . , tK)−min(t1, t2, . . . , tK)<B, transmitting, through an antenna, the uplink signal corresponding to the virtual user to the base station corresponding to each of the virtual users; wherein K is an integer, and K is greater than or equal to 1; B is a preset threshold; t1 is a timing advance of a base station 1 corresponding to a virtual user 1; t2 is a timing advance of a base station 2 corresponding to a virtual user 2; and tK is a timing advance of a base station K corresponding to a virtual user K.
