Ultra-high reliability (UHR) signaling design
This disclosure provides methods, components, devices, and systems for ultra-high reliability (UHR) signaling design. Some aspects more specifically relate to an access point (AP) transmitting a frame including a user info field to a wireless station (STA), where the user info field supports UHR parameters. The user info field may include a subfield indicating a coding scheme for communications, where the subfield includes at least two bits to support at least three coding scheme options. Additionally, or alternatively, the AP may transmit a trigger frame indicating for one or more STAs to communicate via distributed resource units (RUs). The AP may arrange the user info fields in the trigger frame to implicitly indicate respective global cyclic shift delay (CSD) indexes to the STAs. A STA receiving the trigger frame may determine a global CSD index corresponding to the STA according to the order of the user info fields.
