Abstract:
Embodiments of the present invention disclose an uplink MIMO transmission method, including: sending, by a UE, first data to a base station (NodeB) in a first process in an HARQ_RTT, and receiving an acknowledgement character related to the first data and returned by the NodeB; and determining, by the UE according to the acknowledgement character and a rank value to be used for next transmission, data transmission of the first process in a next HARQ_RTT. The present invention further provides a corresponding user equipment and base station. Implementing the method and apparatus provided by the present invention can enable a UE to correctly perform HARQ transmission using MIMO, thereby effectively ensuring performance of MIMO.
