    Abstract: The present invention relates to HARQ, particularly for IEEE 802.11, i.e. Wi-Fi. The invention proposes a transmitting device for supporting such HARQ, in which the order of scrambling and encoding is changed compared to the conventional transmitter. Likewise the invention proposes a receiving device for supporting such HARQ, in which the order of descrambling and decoding is changed compared to the conventional receiver. In particular, the transmitting device is configured to encode at least one data unit using Forward Error Correction (FEC) coding, scramble the encoded data unit based on a scrambling seed, provide an indication of the scrambling seed that is separate from the scrambled and encoded data unit, and transmit the indication of the scrambling seed and then the scrambled and encoded data unit to a receiving device.

    IPC: H04B7/0452

    Abstract: A transmitter of a wireless Access Point (AP) comprising a circuitry configured to conduct an iterative prolonged process and an iterative instantaneous process for optimizing streams grouping to enhance MU-MIMO transmissions throughput. The prolonged process comprises receiving beamforming reports corresponding to streams transmitted simultaneously by the AP to one or more stations, computing an Effective SINR (ESINR) for each stream with respect to other stream(s) based on the beamforming reports and updating a grouping table associated with each stream to include one or more groups presenting best ESINR for the respective stream. The instantaneous process comprising computing the ESINR for one or more of the streams using most recent beamforming report(s) received and updating one or more of the groups in the grouping table to include one or more additional streams presenting best ESINR. For each MU-MIMO transmission, the transmitter selects a best ESINR group from the updated grouping table.
