Abstract: This closure relates to narrowband communication supporting an Internet of Things (IoT) service in a next-generation wireless communication system and, more particularly, to a method and apparatus for transmitting and receiving narrowband synchronization signals. A base station repeats a Zadoff-Chu sequence on each of multiple OFDM symbols; multiplies each component of a cover sequence, having a length corresponding to a number of the multiple OFDM symbols, to all the components of the Zadoff-Chu sequence on each of the multiple OFDM symbols. Then, the base station transmits the NB PSS by using the Zadoff-Chu sequence multiplied by the cover sequence to the one or more UEs.

Abstract: The present invention determines a PUCCH resource based on which serving cell ACK/NACK information is related to, when a user device set as a plurality of serving cells transmits the ACK/NACK information. Moreover, if a PUCCH transmission time matches with a PUSCH transmission time, the present invention does not piggy back ACK/NACK information to PUSCH but transmits the ACK/NACK information through PUCCH.

Abstract: The present invention provides a method by which an MTC terminal measures channel state information (CSI), a method for transmitting CSI, and apparatuses supporting the same. A method by which the MTC terminal feeds back CSI in a wireless access system supporting machine type communication (MTC), according to one embodiment of the present invention, comprises the steps of: receiving allocation information on a limited MTC bandwidth allocated to the MTC terminal calculating CSI; and feeding back the CSI. Here, the CSI can include MTC wideband channel state information (MTC W-CQI) for the limited MTC bandwidth.

Abstract: The present invention relates to a wireless access system supporting 256-ary Quadrature Amplitude Modulation (256QAM), and more particularly, to methods and apparatuses for transmitting and receiving a Physical Multicast Channel (PMCH) to provide Multimedia Broadcast and Multicast Service (MBMS). According to an embodiment of the present invention, a method for receiving a Physical Multicast Channel (PMCH) by a User Equipment (UE) in a wireless access system supporting 256QAM includes receiving a System Information Block (SIB) including information for acquiring a Multicast Control Channel (MCCH), receiving a PMCH carrying an MCCH including Multimedia Broadcast and Multicast Service (MBMS) control information, and receiving a PMCH carrying a Multicast Traffic Channel (MTCH) including MBMS data based on the MBMS control information. 256QAM is not applied to the PMCH carrying the MCCH, and the UE determines a Modulation and Coding Scheme (MCS) and a Transport Block Size (TBS) using a second table supporting 256QAM to receive and demodulate the PMCH carrying the MTCH.

Abstract: One embodiment of the present specification discloses an uplink transmission method in a multi-cell environment in which a single uplink resource is shared. The method may comprise: receiving control information that configures an uplink control channel and an uplink shared channel so that the uplink control channel and the uplink shared channel are not simultaneously transmitted on the same one uplink subframe, wherein the single uplink resource is shared by a first cell and a second cell; selecting any one of the uplink control channel and the uplink shared channel if a first Scheduling Request (SR) for the first cell and Uplink Control Information (UCI) for the second cell are requested to be simultaneously transmitted on the same subframe through the uplink control channel and the uplink shared channel, respectively; sending the selected channel on the uplink subframe.

Abstract: The present specification provides a method and UE for receiving configuration usable for a discovery, which can be used in a small cell scenario. In detail, the UE is configured for receiving measurement configuration for a discovery signal, wherein the discovery signal includes CRS, PSS, and SSS. The discovery may further include a channel status information-reference signal (CSI-RS) depending on a configuration of the CSI-RS. The measurement configuration may include at least one set of configuration elements. The UE performs a measurement on the discovery signal based on the received configuration. Further, the UE receives channel status information-reference signal (CSI-RS) configuration including at least one set of CSI-RS configuration elements used for a zero power CSI-RS, wherein the CSI-RS configuration includes at least one set of CSI-RS configuration elements, each set of CSI-RS configuration elements includes CSI-RS interval information and CSI-RS offset information.
