Abstract
Methods and apparatus for multi-hybrid automatic repeat request (HARQ) transmission are provided. An access point (AP) may transmit a multi-HARQ transmission to a plurality of stations (STAs). The AP may receive a H-ARQ feedback response from the plurality of STAs. The H-ARQ feedback may include a field to indicate that the H-ARQ feedback is a codeword (CW)/CW group (CWG) based acknowledgment. The H-ARQ feedback may include a packet identification (ID). The packet ID may be a HARQ transmission ID, a sequence number, a MPDU ID or a PPDU ID. The packet ID may be carried in a PLCP header. The H-ARQ feedback may be an aggregated CW/CWG acknowledgment. The H-ARQ feedback may be carried in a null data packet (NDP). A PLCP header of the NDP packet may include a wideband PLCP header and a narrow band PLCP header.
