1. A wireless communication terminal, the wireless communication terminal comprising:
a transceiver; and
a processor, wherein the processor is configured to:
receive a first trigger frame for soliciting uplink transmission of one or more terminals from an access point (AP), and
transmit a power save (PS)-poll frame in response to the first trigger frame,
wherein the first trigger frame is received during a specific time when a state of the wireless communication terminal is in an awake state, and
wherein the PS-poll frame is transmitted together with one or more other uplink frames transmitted from one or more other terminals in response to the first trigger frame.
