Abstract: A base station does not transmit any reference signal (RS) for channel measurement in a subframe in which transmission of an RS collides with transmission of a synchronization signal or a broadcast signal or in a resource block including the synchronization signal or the broadcast signal in the subframe. A user equipment assumes that any RS for channel measurement is not transmitted in a subframe or in a resource block when transmission of an RS collides with transmission of a synchronization signal or a broadcast signal in the subframe or in the resource block.

Physical downlink shared channels (PDSCHs) are received on a primary component carrier and PDSCHs are received on a secondary component carrier. The primary component carrier and the secondary component carrier are configured for the terminal. A first acknowledgement (ACK)/negative acknowledgement (NACK) feedback is transmitted for the received PDSCHs on a first physical uplink control channel (PUCCH) resource corresponding to a first antenna port and a second ACK/NACK feedback is transmitted for the received PDSCHs on a second PUCCH resource corresponding to a second antenna port. The first antenna port and the second antenna port are configured for the terminal. The first ACK/NACK feedback and the second ACK/NACK feedback are identical.

Abstract: A method of transmitting uplink signal through a Physical Uplink Shared Channel (PUSCH) by a mobile device in a wireless communication system. The method includes generating multiplexed information by multiplexing a first type of control information and data information; and transmitting the multiplexed information and a second type of control information through the PUSCH. One or more Resource Blocks (RBs) for the PUSCH include N Single Carrier Frequency Division Multiple Access (SC-FDMA) symbols in a slot. The multiplexed information is mapped on a first set of SC-FDMA symbols, and the first set of SC-FDMA symbols includes SC-FDMA symbols other than an (N−3)th SC-FDMA symbol for a reference signal in the slot. The second type of control information is mapped on (N−4)th and (N−2)th SC-FDMA symbols in the slot, and the second type of control information includes Acknowledgement/Negative Acknowledgement (ACK/NACK) information.
