    Abstract: A first uplink channel and a first uplink reference signal for demodulating the first uplink channel may be transmitted within a first TTI having a predetermined time length. A second uplink channel and a second uplink reference signal for demodulating the second uplink channel may be transmitted within a second TTI having the predetermined time length. The first uplink reference signal may be transmitted in the last symbol among symbols in the first TTI, and the first uplink channel may be transmitted in the symbols remaining after excluding the last symbol of the first TTI from the symbols in the first TTI, and the second uplink reference signal may be transmitted in the first symbol among symbols in the second TTI symbols, and the second uplink channel may be transmitted in the symbols remaining after excluding the first symbol of the second TTI from the symbols in the second TTI. The last symbol of the first TTI and the first symbol of the second TTI may be the same symbol.

    Abstract: A user equipment receives a first multiple access (MA) time resource information indicating static MA time resources in which uplink (UL) grant-free UL transmission is permitted among time resources corresponding to a fixed time length Twindow. If UL data (hereafter referred to as first UL data) to be transmitted in one (hereafter referred to as a first static MA time resource) of the static MA time resources exists, the UE transmits the first UL data in the first static MA time resource by means of a predetermined frequency resource. The UE can monitor downlink control information (hereafter referred to as first DCI) in non-static MA time resources, which are not the static MA time resources, among the time resources, and, if the first DCI is received, can transmit UL data (hereafter referred to as second UL data) to the first DCI or receive DL data.

    Abstract: The present disclosure discloses a method for receiving a downlink signal by a UE in a wireless communication system. Particularly, the method may include receiving a synchronization signal block (SSB) including a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcasting channel (PBCH), and obtaining an indicator indicating a subcarrier spacing for the downlink channel from the PBCH, and receiving the downlink signal on the basis of the subcarrier spacing. The indicator may indicate a different subcarrier spacing according to a frequency band in which the UE operates.

    Abstract: Provided is a communication method for supporting various bandwidths. The device detects a synchronization signal transmitted by a wide-band cell and receives a downlink (DL) signal from the wide-band cell on the basis of the synchronization signal. A support bandwidth supported by the device is narrower than a system bandwidth supported by the wide-band cell.

    Abstract: A method for transmitting an uplink control channel for a terminal configured to support multiple transmission time interval (TTI) lengths in a wireless communication system according to an embodiment of the present invention is performed by the terminal and may comprises the steps of: receiving a first physical downlink shared channel (PDSCH) according to a first TTI length at a first time point; receiving a second PDSCH according to a second TTI length differing from the first TTI length at a second time point; and when TTIs for transmitting uplink control channels for the received first PDSCH and second PDSCH overlap, transmitting uplink control information for the first PDSCH and second PDSCH on a physical uplink control channel (PUCCH) having the shorter TTI length among the first TTI length and the second TTI length.
