    摘要： 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.

    摘要： Provided are methods and devices for transmitting/receiving downlink signals in a Wireless communication system. Carrier information is provided to user equipment, the carrier information including cell identifier information which indicates Whether a first cell identifier related to a first carrier operating on one resource block (RB) and a second cell identifier used for a cell-specific reference signal (CRS) on the first carrier are the same or different. If the second cell identifier is the same as the first cell identifier, the user equipment assumes that the number of antenna ports for the CRS on the first carrier is the same as the number of antenna ports for a reference signal defined for NB-IoT (reference signal for NB-IoT, NRS). If the second cell identifier is different from the first cell identifier, the carrier information further includes antenna port number information, and the user equipment assumes that the number of the antenna ports for the CRS is the same as the number of antenna ports based on the antenna port number information.

    摘要： A method for a terminal to receive a synchronization signal is disclosed in the present invention. The method receives a message including a synchronization signal block indicator indicating one or more synchronization signal block groups including at least one transmission synchronization signal block among a plurality of synchronization signal block groups grouped by the prescribed number of candidate synchronization block positions of a synchronization signal block including a primary synchronization signal, a secondary synchronization signal, and a physical broadcast channel signal, and can receive the at least one transmission synchronization signal block based on the message.
