12 Claims

1. A wireless communication terminal comprising: a transceiver configured to transmit and receive wireless signals; and a processor configured to process wireless signals transmitted or received through the transceiver, wherein the processor is configured to: receive a first trigger frame soliciting uplink transmission from an AP (Access Point) to one or more terminals, transmit an uplink PPDU (Physical layer Protocol Data Unit) in response to the first trigger frame, and receive an A-MPDU (aggregate medium access control(MAC) protocol data unit(MPDU)) including an acknowledgment frame for the uplink PPDU and a second trigger frame instructing a next uplink transmission from the AP, wherein the acknowledgment frame and the second trigger frame are aggregated and included in the A-MPDU, and wherein the acknowledgment frame is located before the second trigger frame in the A-MPDU.
