1. A wireless communication terminal comprising:
a transceiver; and
a processor,
wherein the processor is configured to:
receive, by using the transceiver, data from a base wireless communication terminal through a sub-band while the base wireless communication terminal is performing simultaneous transmission to the wireless communication terminal and one or more other wireless communication terminals other than the wireless communication terminal through one or more other sub-bands,
when a transmission of data to the wireless communication terminal from the base wireless communication terminal during the simultaneous transmission is terminated, enter a sleep mode for power saving while a transmission of data to the one or more other wireless communication terminals from the base wireless communication terminal during the simultaneous transmission is going on, wherein a dummy data including value 0 is transmitted from the base wireless communication terminal after the transmission of the data to the wireless communication terminal is terminated during the simultaneous transmission, and the dummy data is transmitted until the transmission of the data to the one or more other wireless communication terminals is terminated, and
wake up from the sleep mode based on an end of the simultaneous transmission,
wherein the wireless communication terminal and the one or more other wireless communication terminals are associated with the base wireless communication terminal.
