Abstract: A method for transmitting an uplink signal by a communication apparatus in a wireless communication system is discussed. The method includes multiplexing control information with at least one of a plurality of data blocks to generate a bit sequence; and transmitting the uplink signal including the bit sequence. When the control information includes a first type of control data, the control information is multiplexed with all of the plurality of data blocks. When the control information includes a second type of control data, the control information is multiplexed only with a specific data block among the plurality of data blocks. The first type of control data includes acknowledgement/negative acknowledgement (ACK/NACK) information, and the second type of control data includes channel quality information.

Abstract: A method for transmitting channel quality information for a downlink channel; a user equipment (UE) therefore; a method for receiving channel quality information for a downlink channel; and a base station therefore are discussed. The method for transmitting channel quality information for a downlink channel includes according to one embodiment receiving, by a user equipment (UE), configuration information on periodic channel state information (CSI) reporting by higher layer signaling; determining, by the UE, a channel quality information index at least based on a number of a specific resource element; and transmitting the determined channel quality information index to a base station. The number of the specific resource element is determined based on a UE-specific reference signal overhead. A resource element allocated for a Channel Status Information-Reference Signal (CSI-RS) is regarded as the specific resource element regardless of transmitting the CSI-RS.
