Enhanced reliability techniques for shared spectrum
Methods, systems, and devices for wireless communications are described. An access point (AP) and a station (STA) may identify an identifier for a shared block acknowledgment (ACK) session between the AP and the STA. The AP and the STA may further identify a set of member APs also for the shared block ACK session. For example, the STA may transmit a probe signal to discover the APs with which to associate. Additionally or alternatively, an AP may broadcast a probe signal to discover the STA. In one example transmission scheme, after associating, a primary AP may transmit a set of protocol data units (PDUs) to the APs, to which the AP may reply with a block ACK. The block ACK may indicate one or more PDUs that were not successfully received. One or more secondary APs may retransmit the PDUs determined to be missing.
