1. A station for facilitating communication in a wireless network for multi-user transmission, the station comprising:
one or more memories; and
one or more processors coupled to the one or more memories, the one or more processors configured to:
process a first request for buffer status received from an access point, wherein the first request for buffer status schedules a first uplink multi-user transmission and indicates a plurality of resources that indicates existence of data to be sent to the access point; and
transmit, during the first uplink multi-user transmission to the access point and in response to the first request for buffer status, a first uplink null data packet and that comprises a signal that indicates existence of data to be sent from the station to the access point, wherein the one or more processors transmits the first uplink null data packet comprises the one or more processors configured to transmit the signal on a first resource of the plurality of resources.
