A device is disclosed comprises at least one processor adapted (330) to determine synchronization information for each of a plurality of orthogonal frequency duplex multiplexing (OFDM) signals (152) in a respective plurality of wireless local area network (WLAN) frames (103, 113, 123). The WLAN frames respectively are transmitted from different transmission addresses and respectively define different reception addresses to be processed by different receivers (104, 114, 124). The at least one processor also instructs transmission of at least one message (402, 505) comprising the synchronization information. The at least one message configures a first device (114) to transmit a first OFDM signal (113) of the plurality of OFDM signals synchronously with a transmission, by a second device (102 or 122), of a second OFDM signal (103 or 123) of the plurality of OFDM signals. A corresponding method and computer program product are also disclosed.
