Abstract: A wireless communication terminal is disclosed. The wireless communication terminal includes a transceiver configured to transmit/receive a wireless signal; and a processor configured to control an operation of the wireless communication terminal. The transceiver transmits a training signal to a base wireless communication terminal based on a sub-frequency band allocated from the base wireless communication terminal, and transmits data to the base wireless communication terminal through the sub-frequency band allocated from the base wireless communication terminal. The training signal is used, by the base wireless communication terminal, for receiving the data from the wireless communication terminal.

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: The present invention relates to a wireless communication system. In particular, the present invention relates to a method including: receiving configuration information on a periodic signal through a higher layer signal, wherein a transmission/reception position of the periodic signal is configured to a first set of symbols within each slot which is set periodically; monitoring a PDCCH associated with a slot configuration of a first slot in order to receive slot configuration information for the first slot in which the transmission/reception position of the periodic signal is present; and performing a process for transmitting/receiving the periodic signal in the first slot, wherein when the first set of symbols within the first slot is designated as a flexible symbol by a higher layer, a transmission/reception of the periodic signal in the first slot is selectively performed according to a detection result of the PDCCH, and wherein the flexible symbol means a symbol whose purpose can be re-designated to DL, UL or flexible according to the slot configuration information of the PDCCH, and an apparatus therefor.

Abstract: A wireless communication terminal communicating wirelessly is provided. The wireless communication terminal includes: a first wireless transceiver for transmitting and receiving a signal transmitted through a first modulation method; a second wireless receiver for receiving a signal transmitted through a second modulation method different from the first modulation method; and a processor. The processor receives a wake-up packet from a base wireless communication terminal through the second wireless receiver, and wakes-up the first wireless transceiver based on the wake-up packet, and maintains the second wireless receiver in a state capable of receiving at least from a time point at which the wake-up packet is received until a time point an exchange of frames with the base wireless communication terminal for the first time through the first wireless transceiver.
