Abstract: A method and apparatus for forming a resource block (RB) structure in a wireless communication system is provided. A user equipment (UE) receives a downlink (DL) signal via first physical resource blocks (PRBs), which are indexed by a network from a center of a band or from a center of a carrier, from the network. And, the UE transmits an uplink (UL) signal via second PRBs, which are aligned with the first PRBs according to synchronization signal (SS) blocks, to the network.

Abstract: The present application discloses a method for transmitting uplink signals through multiple cells in a wireless communication system. Particularly, the uplink signal transmission method comprises: a step of receiving a first downlink signal at a first timing through a first cell and receiving a second downlink signal at a second timing through a second cell; a step of transmitting a first uplink signal, corresponding to the first downlink signal, through the first cell after a first processing time has elapsed since the first timing; and a step of transmitting a second uplink signal, corresponding to the second downlink signal, through the second cell after a second processing time has elapsed since the second timing, wherein, if the first uplink signal and the second uplink signal are transmitted at the same timing, uplink transmission power is allocated first to the uplink signal corresponding to the downlink signal received at the preceding timing between the first timing and the second timing.
