    • This invention provides a method for transmitting uplink control information, which includes: determining, by User Equipment UE, configuration information of its Component Carrier CC; receiving, by UE, a downlink data packet of each CC, and generating acknowledgement/negative acknowledgement ACK/NACK information of the CC to be fed back for each CC independently; and determining indicator information for indicating the ACK/NACK information of the UE that is to be fed back to an evolved Node-B eNB and a channel resource for sending the indicator information according to the configuration information of its CC and whether it is required to send a Scheduling Requirement SR information, and sending an indicator message using the determined channel resource. In the method provided by this invention, by determining the configuration information of the CC allocated to the UE and then coding and mapping the ACK/NACK information of each CC to be fed back as the two-bit indicator information and sending the same, it can be ensured to feed back the ACK/NACK information as much as possible through the SR channel while reducing the CM of the uplink sending signal as much as possible, so as to finally improving frequency spectrum efficiency and uplink throughput of the whole LTE-A system.

    • A method for transmitting an uplink sounding reference signal includes indexing Single Carrier Frequency Division Multiple Access (SC-FDMA)symbols within a single radio frame for transmitting a Sounding Reference Signal (SRS) as a number k, and calculating a value of nSRS according to number k and an index number of the radio frames for transmitting the SRS, determining an index number of a frequency-domain start sub-carrier mapped from time-domain SRS symbol with nSRS, and transmitting the SRS through the sub-carrier with the determined index number determined. Before transmitting the SRS, the start frequency position for SRS should be changed according to the specific frequency-hop pattern to guarantee that the UE may uniformly sound the entire SRS frequency-hop bandwidth after multiple soundings.
