<p>The present invention provides a signal transmission method, system, and device, where the method includes: setting K virtual users, where each virtual user 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 virtual user, the split baseband signal corresponding to each virtual user, and obtaining an uplink signal corresponding to each virtual user; and obtaining timing advances { t 1 ,t 2 ,...,t K } of base stations corresponding to the K virtual users, and when max( t 1 , t 2 ,...,t K )-min( t 1 t 2 ,...,t K ) < B, transmitting, through an antenna, the uplink signal corresponding to the virtual user to the base station corresponding to each virtual user.</p> |
