Abstract: Provided are an operating method for an IAB node including a DU and an MT in a wireless communication system, and a device. The method receives first resource direction information about the DU and second resource direction information about the MT, wherein each of the first and second resource direction information indicates the direction of each resource as being downlink, uplink or flexible. The IAB node determines, for a certain resource from among the resources, whether the DU and the MT can operate at the same time on the basis of the direction indicated by the first resource direction information and the direction indicated by the second resource direction information.

Abstract: A method for receiving a signal by an apparatus in a wireless communication system is discussed. The method includes receiving, in a first time resource within a second time resource configured as 14 number of symbols, a physical channel carrying downlink control information within resource element groups (REGs), and receiving a physical downlink shared channel based on the downlink control information. Further, the REGs are indexed starting from a symbol included in the first time resource, and a starting boundary of the first time resource is determined independently from a starting boundary of the second time resource.

Abstract: The disclosure of the present specification provides a method for receiving a downlink control channel in a low-capability (LC) or low-cost (LC) apparatus. The method may comprise a step of determining a search space for monitoring the downlink control channel, wherein the search space can be defined by a candidate of the downlink control channel according to a set level and a repetition level. Each candidate can be repeated on a plurality of consecutive subframes which start from a start subframe. The location of the start subframe can be determined by a value obtained from an RRC signal. The method may comprise a step of decoding each candidate of the downlink control channel repeated on the consecutive subframes.

Abstract: A user equipment is provided with puncturing information indicating a resource to which downlink data is punctured among time-frequency resources to which the downlink data is allocated. The user equipment may decode the downlink data received in the time-frequency resource on the basis of the puncturing information. The downlink data may be mapped to the time-frequency resource by a combined method of a time-first resource mapping method and a frequency-first resource mapping method, or by a distributed resource mapping method.
