Abstract: The present specification provides a method for transmitting and receiving data by a relay node in a wireless communication system and an apparatus therefor. The relay node receives configuration information from a network node, wherein the configuration information may include a timing offset for transmitting downlink data. The relay node transmits the downlink data to a second relay node on the basis of the configuration information, in which transmission timing of the downlink data may be determined on the basis of the timing offset and a timing advance (TA).

Abstract: Disclosed in the present application is a method by which a terminal, set by a first uplink carrier, receives downlink control information from a base station in a wireless communication system. Particularly, the method comprises the steps of: receiving setting information of a second uplink carrier through an upper layer; receiving, from the base station, the downlink control information for transmission of an uplink signal through the first uplink carrier or the second uplink carrier; and transmitting, to the base station, the uplink signal on the basis of the downlink control information, wherein the last bit of padding bits of the downlink control information is indicator information indicating either the first uplink carrier or the second uplink carrier.

Abstract: An initial access method of an integrated access and backhaul (IAB) node in a wireless communication system and an apparatus using the method are provided. The method includes: receiving, from a parent node, a synchronization signal block (SSB) and system information; and performing a random access procedure with the parent node on the basis of the SSB and the system information, wherein the SSB and the system information are received through a resource allocated to an access link of the parent node, and the random access step is performed through a resource allocated to the backhaul link of the parent node, and the random access step is performed using resources determined differently depending on whether the TAB node is a relay node or a terminal.

Abstract: This specification provides a method for performing an initial access by using a short transmission time interval (TTI) in a wireless communication system. More specifically, the method performed by the UE includes: receiving, from an eNB, system information including control information indicating a transmission time of an uplink signal; transmitting a random access preamble to the eNB; receiving, from the eNB, a random access response message including an uplink grant for transmitting the uplink signal in subframe #n; and transmitting, to the eNB, the uplink signal in subframe #n+k based on the control information, in which the k is a natural number smaller than 6. Accordingly, this specification has an effect that the initial access may be performed quickly by transmitting the uplink transmission of the RACH procedure faster.

Abstract: Disclosed herein is a method for determining a resource area to be allocated to a bandwidth part (BWP) in a wireless communication system. More specifically, the method performed by a terminal includes: receiving, from a network, a first resource allocation field associated with a resource allocation group (RBG) size for a first BWP and a second resource allocation field associated with an RBG size for a second BWP, on the first BWP; and when the size of the first resource allocation field is greater than the size of the second resource allocation field, determining a resource area to be allocated to the second BWP, based on a value of the first resource allocation field, which corresponds to the size of the second BWP, starting from a predefined point.

Abstract: The present disclosure provides a method for transmitting and receiving data based on a grid of a common resource block (RB) in a wireless communication system. More specifically, the method performed by a user equipment includes receiving a synchronization block from a base station; receiving, from the base station, first offset information representing an offset between a lowest subcarrier of a lowest resource block of the SSB and a first reference point based on a specific subcarrier spacing; receiving, from the base station, control information including information on the specific subcarrier spacing and information on a difference between a subcarrier spacing based reference point, to which the SSB is received, and the first reference point; and configuring a grid of a common resource block based on the first offset information and the control information.

Abstract: The present specification provides a method for configuring a common search space (CSS) in a wireless communication system. Specifically, a method performed by a network may comprise the steps of: acquiring, from at least one terminal, information on a bandwidth of the at least one terminal; determining a particular subband indicating a bandwidth unit available for communication with the terminal; determining the number of particular subbands on the basis of the determined particular subband and the acquired information on the bandwidth of the terminal; and mapping, on the basis of the determined number of particular subbands and the aggregation level of the CSS, a part of the aggregation level to each particular subband. Therefore, it is possible to efficiently use radio resources through the CSS configuration method proposed in the present specification.
