1. A wireless communication terminal, the terminal comprising:a transceiver configured to transmit and receive a wireless signal; and
a processor configured to process wireless signals transmitted or received through the transceiver,
wherein the processor is configured to, in a power save mode:
receive a trigger frame by transition to awake state, wherein the trigger frame is received at or after a predetermined time, and
transmit an uplink frame in response to the trigger frame,
wherein the uplink frame is transmitted, using orthogonal frequency domain multiple access (OFDMA), with one or more other uplink frames transmitted from one or more other terminals in response to the trigger frame.
