Abstract: A method and apparatus for transmitting/receiving a downlink channel in a wireless communication system are provided. A downlink control channel and a downlink data channel corresponding to the downlink control channel are transmitted/received within a transmission time interval (TTI). A reference signal (RS) of an antenna port used for transmission of both the downlink control channel and the downlink data channel is transmitted/received on an OFDM symbol with the downlink control channel, and an RS of an antenna port used only for transmission of the downlink data channel is transmitted in the remaining OFDM symbol(s) of the TTI.

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.

Abstract: A method for performing a measurement in a wireless communication system and an apparatus for the same are disclosed. Particularly, a method by which a terminal performs a measurement in a wireless communication system comprises the steps of: receiving, by the terminal, a discovery signal; and measuring, by the terminal, reference signal received power (RSRP) and/or reference signal received quality (RSRQ) on the basis of the discovery signal, wherein the number of antenna ports of a cell-specific reference signal (CRS) cannot be applied to the discovery signal-based measurement.

Abstract: A method for transmitting a physical uplink shared channel (PUSCH) is discussed. The method is performed by a wireless device and includes receiving downlink control information (DCI), which is repeated on a plurality of downlink subframes, identifying a last subframe on which the repetition is completed, determining that the identified last subframe is not used for determining a start subframe to repeatedly transmit the PUSCH, substituting the last subframe with a first subframe usable for determining the start subframe to transmit the PUSCH after the identified last subframe, based on the determination that the identified last subframe is not used for determining the start subframe; determining the start subframe to transmit the PUSCH, based on the first subframe other than the last subframe, and transmitting the PUSCH repeated over a plurality of subframes starting from the determined start subframe.

Abstract: The present specification provides a reception method of a machine type communication (MTC) device. The reception method can comprise the steps of: receiving a control channel through the entire system bandwidth on first and second orthogonal frequency division multiplexing (OFDM) symbols of a subframe; and determining whether to receive a data channel only in a reduced bandwidth compared with the system bandwidth from the third symbol of the subframe. At this point, when the control channel does not continue up until a third symbol of the subframe, the data channel can be received in a reduced bandwidth compared with the system bandwidth from the third symbol of the subframe.

Abstract: A method and apparatus for receiving a downlink message in a wireless communication system is provided. A user equipment (UE) receives scheduling information for a downlink message via a dedicated common search space (D-CSS) in a first narrowband from a network, and receives the downlink message in the second narrowband from the network. The D-CSS may schedule resources for random access response (RAR)/Msg4 and initial configuration of UE-specific configurations before UE-specific narrowband (NB) is configured. CSS in UE-specific NB may schedule resources for RAR/Msg4/paging and reconfiguration of UE-specific configurations after UE-specific NB is configured.
