Abstract: Techniques for power saving by remote wireless mobile devices are provided, in particular by stations (STAs) during downlink (DL) multiple-user multiple-input and multiple-output (MU-MIMO) transmissions in an Institute of Electrical and Electronics Engineers (IEEE) 802.11ay network when reverse direction (RD) transmissions are either enabled and not enabled. Various embodiments enable each STA in a group of STAs to determine an order in which the STAs are requested to send a block acknowledgement (BACK) and which STAs will be granted an RD transmission. Further, a duration of each RD transmission is provided to each STA. Based on the provided information, each STA can determine times to enter a power saving mode. Other embodiments are described and claimed.

Abstract: Methods, apparatuses, computer readable media for coordinated transmission among virtual access points (VAPs). An apparatus of a wireless device comprising processing circuitry is disclosed. The processing circuitry is configured to determine to share a multi-station uplink (UL) and/or downlink (DL) transmission opportunity (TXOP) with two stations that are associated with two virtual access points (VAPs), where each of the two stations is associated with one of the two VAPs. The processing circuitry further configured to determine UL resource allocations for the two stations for a trigger frame based on information received from the two VAPs, and to encode the trigger frame for the multi-station UL TXOP, the trigger frame comprising a common VAP identification (ID) of the two VAPs, UL resource allocations for the two stations, and multi-basic service set (M-BSS) identifications (IDs) for each of the two stations.
