The invention relates to the technical field of wireless communication, and discloses a method for determining an uplink transmission diversity mode. The method comprises the following step of: transmitting a high-speed shared control channel (HS-SCCH) command to user equipment (UE) on the HS-SCCH of high-speed special shared channels, wherein the HS-SCCH command comprises command type information, the command type information indicates the uplink transmission diversity mode, and the transmission diversity mode is an open loop transmission diversity mode or a closed loop transmission diversity mode. The invention also discloses a communication device. According to the embodiment provided by the invention, the uplink transmission diversity mode can be determined according to the actual situation so that the system properties such as system capacity, coverage range and the like are maximized in the UE during uplink transmission diversity.
