Abstract: A method for a wireless device to which a plurality of serving cells are assigned transmitting uplink control information (UCI) in a wireless communication system is provided. The wireless device transmits uplink data in a subframe to a physical uplink shared channel (PUSCH), and transmits UCI including a hybrid automatic repeat request (HARQ) ACK/NACK and periodic channel state information (CSI) in the subframe to a physical uplink shared channel (PUCCH). The PUCCH and the PUSCH have the same demodulation reference signal (DMRS) location within the subframe.

Abstract: A method of transmitting data signals comprising a shortened downlink shared channel (sPDSCH) by a base station in a wireless access system supporting an unlicensed band, the method includes performing a carrier sensing to check whether the unlicensed band is in an idle state or not; and transmitting, to a user equipment (UE), the data signals comprising the sPDSCH based on the carrier sensing via the unlicensed band during a channel occupancy time; wherein the sPDSCH is transmitted in a first time interval or a second time interval following the first time interval, wherein the first time interval starts from a starting point of the transmission of the data signal, and wherein the second time interval ends at a subframe boundary of a licensed band.

Abstract: Provided are a method for reporting a power headroom and an apparatus using the same. The apparatus computes and reports a power headroom for a physical uplink shared channel (PUSCH) that is transmitted in a first transmission period of a first band having a first subcarrier interval. The power headroom is computed on the basis of at least one second transmission interval of a second band having a second subcarrier interval which overlaps with the first transmission interval.

Abstract: A method and apparatus for performing an initial access procedure in a wireless communication system is provided. A low cost user equipment (UE) transmits a list of capabilities to a network, and receives a reject message from the network when at least one of the capabilities is not supported by the network. The list of capabilities may be transmitted during a random access procedure via a random access preamble on a physical random access channel (PRACH) or a message 3 on a physical uplink shared channel (PUSCH). The reject message may be received during the random access procedure a random access response or an acknowledge message for the message 3.
