    Abstract: A method is provided for transmitting, by a user equipment (UE), a demodulation reference signal (DMRS) for a physical uplink shared channel (PUSCH) in a wireless communication system. First, second, and third DMRS sequences associated with first, second, and third layers respectively are generated. First, second, and third cyclic shifts are allocated to the first, second, and third DMRS sequences respectively, The first, second, and third DMRS sequences are transmitted to a base station. The first, second, and third cyclic shifts are respectively determined based on first, second and third cyclic shift values, which are indicated by a cyclic shift field in downlink control information (DCI) received through a physical downlink control channel (PDCCH). The first and second cyclic shift values are separated by a maximum separation value corresponding to a total number of cyclic shifts and being determined for transmission of DMRS signal in the system using four layers.

    Abstract: A method for transmitting ACK/NACK (Acknowledge/Negative ACK) information at a user equipment in a wireless communication system, and a user equipment therefore are discussed. The method according to one embodiment includes generating an ACK/NACK payload for a plurality of carriers, the ACK/NACK payload including a plurality of concatenated ACK/NACK sets. Each ACK/NACK set is associated with a respective one of the plurality of carriers and has one or more ACK/NACK bits. The method further includes transmitting the ACK/NACK payload through a PUCCH (Physical Uplink Control Channel) or PUSCH (Physical Uplink Shared Channel). The ACK/NACK payload includes an ACK/NACK bit for a semi-persistent scheduled downlink signal. The ACK/NACK bit for the semi-persistent scheduled downlink signal is positioned at an end of a corresponding ACK/NACK set, not an end of the ACK/NACK payload.
