Abstract: A method and system for generating an extended range (ER) physical layer protocol data unit (PPDU) is disclosed. The PPDU has a legacy portion of the ER PPDU which comprises one or more of a legacy short training field (L-STF), a legacy long training field (L-LTF), and a universal signaling (U-SIG) field and an ER portion of the ER PPDU which is appended to the legacy portion. The ER portion comprises one or more repetitions of a ER short training field (ER-STF), a ER long training field (ER-LTF), a ER-signal (ER-SIG) field, and a ER data field. In an example, signals indicative of the one or more repetitions for a same field are combined by a receiver to increase a signal to noise ratio of a field.

Abstract: One example discloses a communication device, includes: a coexistence engine configured to be coupled to an aggressor radio and a victim radio; wherein the aggressor radio is configured to transmit messages; wherein the victim radio is configured to receive messages; wherein the aggressor and victim radios share a communication resource; and wherein the coexistence engine is configured to detect whether an interference metric between the aggressor radio and the victim radio is violated each time the aggressor radio transmits a transmit message through the communications resource.
