Abstract: A disclosure of this specification provides a method performed by a wireless device for determining a transport block size (TBS). The method may include the steps of determining a number of resource elements (REs) within a slot, calculating a value related to the TBS, based on the determined number of REs and a code rate, comparing the calculated value with a pre-determined threshold value, determining the TBS according to the comparison, wherein, if the calculated value is smaller than or equal to the pre-determined threshold value, the TBS may be determined using a predetermined table.

Abstract: One downlink control information DCI may be divided into first DCI and second DCI to be transmitted/received. The first DCI may be transmitted/received within a control region of a first TTI of a first time length. The first DCI may include information about the second DCI in a second TTI of a second time length shorter than the first time length. The first DCI may be transmitted/received using first decoding candidates for transmission of the first DCI among decoding candidates in the search space in the control region of the first TTI. The decoding candidates other than the first decoding candidate among the decoding candidates in the search space may be used for transmission/reception of legacy DCI.

Abstract: Provided herein is a method and apparatus for configuring a physical uplink control channel (PUCCH) resource in a wireless communication system and, most particularly, in a new radio access (NR) technology. More specifically, when and/or for which operation the default PUCCH resource is being used may be defined. For example, a wireless device may receive information on a default physical uplink control channel (PUCCH) resource, and the wireless device may transmit uplink control information (UCI) to a gNB by using the default PUCCH resource, only before establishing a radio resource control (RRC) connection with the gNB.

Abstract: Provided herein are a method for performing wireless communication by a first apparatus and an apparatus for supporting the same. The method may include the steps of receiving a configuration related to a Uu bandwidth part (BWP) from a base station, and receiving a configuration related to a sidelink (SL) BWP from the base station. Herein, based on a numerology of the Uu BWP and a numerology of the SL BWP being different, the first apparatus may not perform SL communication on the SL BWP.

Abstract: Disclosed in the present application is a method for transmitting and receiving signals to and from a base station by a terminal in a wireless communication system. Specifically, the method comprises the steps of: receiving, from the base station, a downlink data signal through a downlink resource of a first transmission time interval (TTI) length; and transmitting, to the base station, an uplink control signal, as a response to the downlink data signal, through an uplink resource of a second TTI length different from the first TTI length, wherein the uplink resource of the second TTI length is determined on the basis of the uplink resource of the first TTI length corresponding to the downlink resource of the first TTI length.

Abstract: Disclosed herein is a method for receiving a demodulation reference signal (DMRS) in a wireless communication system. In particular, the method may include receiving a synchronization signal/physical broadcast channel (SS/PBCH) block, acquiring information about control resource set (CORESET) #0 from a PBCH included in the SS/PBCH block, receiving a physical downlink control channel (PDCCH) through CORESET #0, and receiving a physical downlink shared channel (PDSCH) scheduled based on the PDCCH and a DMRS for the PDSCH, wherein, based on the PDCCH being addressed to a system information-radio network temporary identifier (SI-RNTI), a reference point for the DMRS may be subcarrier #0 of a resource block (RB) having a lowest number among RBs included in CORESET #0.
