The present disclosure discloses an information feedback method for uplink closed loop transmission diversity, which includes: a base station allocates each Fractional Dedicated Physical Channel (F-DPCH) to at least one user; and the base station takes at least one F-DPCH as a feedback channel and arranges information of different users in each said F-DPCH by time division multiplexing, wherein information of at least one user in the F-DPCH includes feedback information of the uplink closed loop transmission diversity and an uplink Transmission Power Control (TPC) command. The present disclosure further discloses an information feedback device for uplink closed loop transmission diversity. Through the solution of the present disclosure, information feedback of the uplink closed loop transmission diversity can be implemented, when the information is a weight, the problem of weight feedback of the uplink closed loop transmission diversity is solved, and a user side of a High Speed Uplink Packet Access (HSUPA) system is facilitated to complete an operation of transmission diversity.
