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: A method is provided for transmitting a power headroom report at a user equipment (UE) in a wireless communication system. The UE configures a first cell group having a primary cell (PCell) and a second cell group having one or more secondary cells (SCells). The UE transmits the power headroom report. If the first cell group and the second cell group are managed by a same base station, the power headroom report indicates power headroom information regarding the first and second cell groups. If the first cell group and the second cell group are managed by different base stations, the power headroom report indicates power headroom information regarding only one of the first cell group and the second cell group.

A method by which a terminal capable of supporting 256 QAM in a wireless access system reports CSI, according to one embodiment of the present invention, comprises the steps of: receiving a higher-layer signal for configuring a first rank indicator (RI) reference process in the terminal; measuring a channel quality for one or more CSI processes associated with the first RI reference process configured in the terminal; selecting a channel quality indication (CQI) index by using only a first CQI table or a second CQI table for the one or more CSI processes; and reporting the CSI including the CQI index. Here, the first CQI table can support up to 64 QAM and the second CQI table can support up to 256 QAM, and only the same CQI table can be applied to the one or more CSI processes associated with the first RI reference process.
