The subject specification comprises a cognitive relay communications management (CRCM) component associated with a primary communication system, wherein the CRCM component controls relaying at least a portion of transmitted communications from a secondary source device (SSD) transmitting data to a secondary destination device (SDD) associated with a secondary communication system, in accordance with a specified relay protocol, such as a buffered decode-and-forward protocol. The CRCM component identifies when the secondary relay station (SRS) is not transmitting on the relay-destination (R-D) link and the source-relay link is not blocked, and, in such instance, allows transmission of a packet from the SSD to the SRS. The SRS forwards the packet to the SDD when the CRCM component identifies when the R-D link is not blocked. The SRS and/or SSD remove the packet from their respective queues when an acknowledgement message(s) is received from the SDD and/or SRS, respectively.
