Abstract: A base station of a wireless communication system is disclosed. The base station of the wireless communication includes a communication module; and a processor configured to control the communication module. The processor receives a radio resource control (RRC) signal from a base station of the wireless communication system through the communication module and determines a time-frequency resource corresponding to at least one resource-set indicated by the RRC signal. The processor receives a physical control channel from the base station through the communication module, determines a time-frequency resource domain in which physical data channel reception of the terminal is scheduled by the physical control channel, and receives a physical data channel based on a time-frequency resource in which the physical data channel reception of the terminal is scheduled and a time-frequency resource in which the at least one resource-set overlap. The resource-set is a set of time-frequency resources.

Abstract: A base station and a user equipment of a wireless communication system are disclosed. Each of the base station and the user equipment of the wireless communication includes a communication module; and a processor. The processor is configured to receive signaling information related to the start of uplink (UL) transmission from the base station through the communication module. The processor is configured to determine whether to perform a UL transmission using a partial subframe based on the signaling information. When the processor performs the UL transmission using the partial subframe, the processor is configured to determine a symbol configuration of the partial subframe based on the signaling information and perform, through the communication module, the UL transmission using the partial subframe according to the symbol configuration. At this time, the partial subframe is a subframe which occupies less than 14 symbols.
