Abstract: A wireless communication terminal communicating wirelessly with a base wireless communication terminal and unassociated with the base wireless communication terminal is disclosed. The wireless communication terminal includes: a transceiver; and a processor configured to receive, by using the transceiver, a multi-station Block ACK frame which indicates whether at least one of MAC frames transmitted from at least one of wireless communication terminals is received by using a first field of the multi-station Block ACK frame for indicating an association identifier corresponding to an association of each of the at least one of wireless communication terminals and the base wireless communication terminal, from the base wireless communication terminal, and determine whether a MAC frame transmitted from the wireless communication terminal is received by the base wireless communication terminal based on whether a second field of the multi-station Block ACK frame includes a MAC address of 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: Provided is a wireless communication terminal that wirelessly communicates with a base wireless communication terminal. The wireless communication terminal includes a transceiver, and a processor. The processor is configured to set an integer selected from a range of 0 to a value equal to or smaller than an OFDMA Contention Window (OCW) as a counter for random access, receive a trigger frame for triggering random access using one or more resource units (RUs) allocated for the random access from the base wireless communication terminal using the transceiver, decrement a value of the counter based on the one or more RUs allocated for the random access, randomly select one RU based on the one or more RUs allocated for the random access when the value of the counter is 0 or reaches 0, and attempt transmission to the base wireless communication terminal using the selected RU.
