Abstract
A wireless communication protocol which operates with multi-link devices (MLDs) having simultaneous transmit and receive (STR) link pairs to allow transmitting a long MU PPDU by an originator on a first link, which is acknowledged (Ack) by a recipient on a second link. The Ack on the second link may be on a single resource unit (RU) which may be shared by multiple stations. The Ack may be received during the MP PPDU on the first link, making it a quick Ack. In many cases this allows the originator to perform a retransmission within the same PPDU, thus especially benefitting real-time traffic which is latency sensitive.
