US 11,057,254 B2 · Control fields for null data packet feedback reports

Abstract

Apparatuses, computer readable media, and methods for control field for null data packet feedback report trigger are disclosed. A station is disclosed, the station comprising processing circuitry configured to: decode a media access control (MAC) protocol data unit (MPDU) comprising an A-control field of type null data packet (NDP) feedback report poll comprising a feedback type field and an indication of a resource unit (RU). The processing circuitry further configured to determine whether the station is scheduled to respond to the A-control field of type NDP feedback report poll, and if the station is scheduled to respond to the A-control field of type NDP feedback report poll, configure the station to transmit a response to a feedback type indicated by the value of the feedback type field on the RU. Apparatuses, computer readable media, and methods for short block acknowledgment with NDP are disclosed.
