Abstract: A method for transmitting channel quality information for a downlink channel. The method according to one embodiment includes receiving, by a User Equipment (UE), configuration information on periodic channel state information (CSI) reporting by higher layer signaling; and determining, by the UE, a channel quality information index at least based on a UE-specific reference signal overhead. The UE-specific reference signal overhead is determined according to a rank value. The method according to the one embodiment further includes transmitting the determined channel quality information index to a base station. The channel quality information index is determined further based on an assumption of no resource element allocated for a Channel Status Information-Reference Signal (CSI-RS).

Abstract: A method is described for transmitting signals at a communication apparatus in a wireless communication system supporting a plurality of component carriers. A physical uplink shared channel (PUSCH) with uplink control information (UCI) and a PUSCH without the UCI are simultaneously transmitted using the plurality of component carriers. A predefined transmission power determination scheme is used to determine the transmission power of the PUSCH with the UCI, and determine the transmission power of the PUSCH without the UCI. If a total transmission power of the PUSCH with the UCI and the PUSCH without the UCI exceeds a value corresponding to a maximum transmission power configured for the communication apparatus, the determined transmission power of the PUSCH without UCI is adjusted while maintaining the determined transmission power of the PUSCH with the UCI.
