Abstract: The present invention discloses a method for reporting channel state information, comprising the following steps of: acquiring, by UE, information about at least two sets of CSI RSs, wherein the information about CSI RSs comprises time domain resource and frequency domain resource occupied by CSI RSs; and measuring, by the UE, a reference signal according to the information about at least two sets of CSI RSs, determining channel state information, and reporting the channel state information to a base station. Another aspect of the present invention further provides a device for reporting channel state information. By the technical solutions provided by the present invention, after pre-coding the CSI RSs, the system performance can be improved, and the resources occupied by the CSI RSs may be greatly saved in practical applications, so that more downlink physical resources may be used for transmission of physical downlink shared channels (PDSCH), thereby increasing the throughput of downlink traffic.

Abstract: A method for implementing uplink transmission in a flexible frequency division duplex (FDD) system is provided. A flexible FDD supported user equipment (FFUE) receives signaling from an evolved node B (eNB), obtains an uplink carrier configuration, and performs physical uplink shared channel (PUSCH) transmission by way of synchronous HARQ of 8 ms, synchronous HARQ of 10 ms, or asynchronous hybrid automatic repeat request (HARQ). According to the solution provided by the present invention, uplink transmission in the FDD system can be realized with low complexity, and the system performance of the FDD system is improved.
