    Abstract: A method of transmitting a reference signal in a wireless communication system, and an apparatus therefore. The method according to one embodiment includes selecting one or more values among a set {0, 3, 6, 8, 10}; cyclically shifting a base sequence based on the one or more values selected from the set {0, 3, 6, 8, 10}; and transmitting the reference signal based on the cyclically shifted base sequence to a base station. The reference signal is transmitted on a first orthogonal frequency division multiplexing (OFDM) symbol and a second OFDM symbol. The first OFDM symbol is a second OFDM symbol among 7 OFDM symbols in one slot. The second OFDM symbol is a sixth OFDM symbol among the 7 OFDM symbols in the slot.

    Abstract: A method is described for transmitting a control signal in a wireless communication system. A wireless communication system supporting multiple antennas, transmits, by a user equipment (UE), a control signal on an uplink control channel at a subframe i. Furthermore, an uplink transmit power PPUCCH(i) for the uplink control channel at the subframe i is determined based on a mathematical equation. Additionally, the mathematical equation includes a min function and uses parameters including PCMAX(i), P0—PUCCH, ΔF—PUCCH(F), g(i), PL, Δ(M) and PL where PCMAX(i) is a configured UE transmit power in subframe i, P0—PUCCH is a parameter composed based on provisions by a higher layer, ΔF—PUCCH(F) is a parameter provided by the higher layer, PL is a downlink pathloss estimate calculated in the UE, and g(i) is a value relating to a UE specific value.

    Abstract: A method and device for transmitting an uplink signal in a wireless communication system is provided. A user equipment transmits a physical uplink shared channel (PUSCH) on a SRS subframe for a first serving cell to a base station if a SRS transmission on the SRS subframe for the first serving cell is overlapped with an uplink transmission for a second serving cell. The PUSCH is transmitted on remaining orthogonal frequency division multiplexing (OFDM) symbols in the SRS subframe except a single OFDM symbol reserved for the SRS transmission regardless of whether a SRS is transmitted on the single OFDM symbol or not.

    Abstract: A method and user equipment for performing an uplink transmission in a wireless communication system, are discussed. The method includes allocating transmission power to a first uplink transmission and a second uplink transmission when a total power in a transmission period including at least one or more OFDM symbols exceeds maximum power, wherein each of the first and second uplink transmissions is one of physical uplink shared channel (PUSCH) transmission, physical uplink control channel (PUCCH) transmission, physical random access channel (PRACH) transmission and sounding reference signal (SRS) transmission; and performing the first and second uplink transmissions according to the allocated transmission power, wherein the allocation of the transmission power is performed according to priority information.
