Abstract: Multiple access points (APs) that transmit jointly at the same time to one or more stations (STAs) need logically to be connected via a link, e.g. a backhaul link. The master AP creates physical layer input data units (PSDUs) to be transmitted during joint transmission and conveys it via the link to one or more slave APs. It may happen that a STA receives the PSDU or parts of it erroneously, in which case a retransmission takes place. A mechanism that allows to reuse the PSDU, which was conveyed by the master AP via the link to the slave AP for the initial transmission, for any subsequent retransmission. Thereby, the bandwidth requirement of the backhaul link is significantly lowered when retransmissions take place. In particular, the difficulty that the PSDU contents change within a retransmission is addressed.
