Multi-basic service set uplink time alignment
This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for multi-basic service set (BSS) time alignment. In one implementation, an access point (AP) may determine a first transmission parameter for a first trigger transmission to be sent to a station (STA) belonging to the first BSS. The first transmission parameter may include a transmission order for time-separated trigger transmissions, non-overlapping bandwidths for frequency-separated trigger transmissions, trigger data precoding information for spatially-separated trigger transmissions, or a combination thereof. The AP may transmit the first trigger transmission to the first STA, and in response, receive a first synchronized transmission from the first STA. The first synchronized transmission may be synchronized, for example, aligned in time, with a second synchronized transmission from a second STA of a second set of STAs in a second BSS.
