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: The present invention may provide a method and apparatuses for transmitting and receiving a downlink/uplink physical channel when an in-band operation is supported by a radio access system that supports a narrow band Internet of things (NB-IoT). As an embodiment of the present invention, a method for receiving a physical downlink broadcasting channel (M-PBCH) by a terminal in a radio access system that supports a narrow band Internet of things (NB-IoT) system may comprise the steps of: receiving a higher layer signal indicating an in-band deployment mode; receiving a narrow band primary synchronization signal (M-PSS) and a narrow band secondary synchronization signal (M-SSS), configured for the NB-IoT systems; obtaining a cell identifier (N-Cell ID) of the NB-IoT system from the M-SSS; and receiving an M-PBCH using the N-Cell ID in the in-band deployment mode. In this instance, the in-band deployment mode indicates that the NB-IoT system is configured in a band of a legacy LTE system.
