Abstract: A system and method for triggering beamformed uplink (UL) physical layer protocol data units (PPDUs) are disclosed. The system comprises an access point (AP) and one or more stations (STAs). The AP sends a soliciting frame to the one or more STAs, wherein the frame comprises a null data packet, NDP, request, NDPR, indicator and receive an NDP PPDU from each of the one or more solicited STAs. The AP, then computes the precoder for each of the one or more solicited STAs and send the one or more solicited STA a trigger frame with a beamforming report. The AP receives from each of the STAs one or more beamformed UL data packets and sends a block acknowledgement to the one or more solicited STAs indicating the successful receipt of the one or more beamformed UL data packets.

Abstract: The present disclosure relates to MU-MIMO signaling in wireless communications. To this end, the disclosure proposes a wireless transmitting device being configured to: obtain a compressed-mode PPDU that comprises one or more SC fields, wherein each SC field corresponds to one MU-MIMO group of the one or more MU-MIMO groups and is indicative of a spatial stream configuration for user devices of that MU-MIMO group; and transmit the PPDU to the user devices of the one or more MU-MIMO groups over a predetermined BW. Further, this disclosure also proposes a user device being configured to: receive a compressed- mode PPDU from a wireless transmitting device; and decode the PPDU to obtain a SC field corresponding to the MU-MIMO group that the user device belongs to.
