Abstract: Various examples pertaining to efficient trigger-based (TB) multi-user (MU) uplink (UL) transmissions in wireless local area networks (WLANs) are described. A stations (STA) receives a trigger frame from an access point (AP), with the trigger frame assigning one or more resource units (RUs) corresponding to one or more subchannels of a plurality of subchannels. The STA then performs a transmission using the assigned one or more RUs responsive to receiving the trigger frame. In an event that at least one subchannel of the plurality of subchannels is detected as being busy, the one or more subchannels may include a subset (e.g., some but not all) of the plurality of subchannels.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a station (STA). In certain configurations, the STA transmits a request-to-send (RTS) frame in an enhanced long range (ELR) format for obtaining a transmission opportunity (TXOP). The STA receives a first clear-to-send (CTS) frame in the ELR format or a non-ELR format responding to the RTS frame. In response to receiving the first CTS frame, the STA transmits data in the ELR format in the TXOP. In certain configurations, the STA further receives an acknowledgement in the same format as the first CTS frame for responding to the data being transmitted. In certain configurations, prior to transmitting the RTS frame, the STA transmits a CTS-to-Self frame in the non-ELR format.

Abstract: Embodiments of the present invention are drawn to methods and electronic devices capable of performing coordinate spatial reuse for wirelessly transmitting data on a channel in coordination with another wireless AP operating an overlapping BSS using the same wireless channel. The device can perform RSSI measurements and generate Per-RU RSSI reports including the RSSI measurements information for transmission to another wireless AP. The RSSI measurement can be performed by the device based on power levels detected when receiving TB PPDUs transmitted by wireless STAs responsive to trigger frames, for example. Based on the Per-RU RSSI report, a wireless AP can be configured to transmit data to an associated wireless STA without causing significant interference when another AP of the overlapping BSS is also transmitting, and can schedule frames for transmission from associated wireless STAs accordingly.
