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: Examples of the present invention provide a method for allocating Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) channel resources supporting transmit diversity and channel selection. The method includes: receiving, by a UE, Physical Downlink Control Channel (PDCCH) information and Physical Downlink Shared Channel (PDSCH) data from a base station through two Carrier Components (CCs); obtaining, by the UE according to specific indication information, Physical Uplink Control Channel (PUCCH) channel resources required for transmitting HARQ-ACK feedback information using a transmit diversity technique; and transmitting, by the UE, the HARQ-ACK feedback information on the obtained PUCCH channel resources adopting the transmit diversity technique. According to the method provided by the examples of the present invention, it is possible to allocate HARQ-ACK channel resources to the UE reasonably and avoid waste of channel resources in the premise that channel selection and SORTD technique are supported.
