Abstract: A method and apparatus for allocating resources to a low cost user equipment (UE) in a wireless communication system is provided. A base station (BS) allocates resource blocks including a punctured direct current (DC) subcarrier to a low cost UE, and communicating with the low cost UE by using the allocated resource blocks. The allocated resource blocks may not be located at center of a set of resource blocks that the low cost UE can access at a given subframe.

Abstract: A user equipment of the present invention generates a preamble sequence, which includes a base sequence N number of times. The user equipment maps, by comb-type, the base sequence in a frequency domain, and maps the base sequence to one of N kinds of frequency locations, thereby generating the preamble sequence. The user equipment transmits a random access preamble including the preamble sequence.

Abstract: The present disclosure provides an operation method of a terminal and a base station in a wireless communication system supporting an unlicensed band, and an apparatus supporting same. As a specific example, the present disclosure comprises an operation method of a terminal and an operation method of a base station corresponding thereto, by which a terminal can obtain timing information relating to a unlicensed band on the basis of a PBCH payload in a synchronization signal/physical broadcast channel (SS/PBCH) block and a demodulation reference signal (DMRS) sequence for the PBCH.

Abstract: The present invention discloses a method for a user equipment to receive system information in a wireless communication system. Particularly, the method is characterized in detecting a first synchronization signal block configured with a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS) and a Physical Broadcasting Channel (PBCH) at a specific frequency position, determining a presence or non-presence of system information corresponding to the first synchronization signal block within a first synchronization raster corresponding to a specific frequency position based on a system information indicator included in the PBCH, and if the system information corresponding to the first synchronization signal block is determined as not existing, determining a second synchronization raster having system information exist therein based on the system information indicator.

Abstract: This specification provides a method of transmitting and receiving data in a wireless communication system and an apparatus therefor. Specifically, a method for transmitting and receiving data in a wireless communication system by a user equipment includes receiving downlink control information from a base station and receiving downlink data from the base station through a downlink shared channel configured based on the downlink control information, wherein when the downlink data is broadcasted, a bundling size for the downlink shared channel is configured as a pre-defined value.

Abstract: A method of receiving a downlink (DL) signal by a user equipment (UE) operating on a frequency band above 6 GHz in a wireless communication system is discussed. The method includes receiving system information including first information related to one or more synchronization signal (SS) and PBCH (SS/PBCH) block groups and second information related to one or more SS/PBCH blocks within each of the one or more of SS/PBCH block groups; and receiving the DL signal in resources other than resources used for the one or more SS/PBCH blocks within each of the one or more of SS/PBCH block groups indicated by the first and second information.

Abstract: The present invention discloses a method of transmitting a Physical Random Access Channel (PRACH) by a terminal in a wireless communication system. Specifically, the method includes: receiving first information related to a Synchronization Signal Block (SSB) and second information related to PRACH resources; and transmitting the PRACH on a valid PRACH resource among the PRACH resources based on the first and second information. In this case, valid PRACH resource may be a PRACH resource allocated after symbols in which the SSB is received among the PRACH resources included in a PRACH slot related to the second information.
