Abstract
Disclosed is a transmission diversity method in a mobile communication system, by which optimal transmission diversity can be provided in case that a base station of the mobile communication system uses at least one transmitting antenna. The present invention includes the step of having a transmitting side transmit signals using a plurality of antennas wherein a transmission signal of a second antenna differs from a transmission signal of a first antenna in a predetermined phase.
Claims7
