Back-to-back uplink transmissions from multiple stations

An apparatus for communications between an access point (AP) and a plurality of wireless stations (STAs) in a wireless local area network (WLAN), comprising:

• a memory configured to store data;
• and
• one or more processors communicatively coupled with the memory, wherein the one or more processors and the memory are configured to:
• transmit, from the AP, a control frame to the plurality of STAs, wherein the control frame contains configuration information related to a plurality of consecutive transmission slots;
• and
• receive, at the AP, back-to-back uplink (UL) response frames from the plurality of STAs in the plurality of consecutive transmission slots.
