Patent number: 9565567Abstract: In one aspect the embodiments of the invention provide a method that includes transmitting a first frame comprising a first type of message from a first node for reception by a second node. The first node is associated with a first wireless communication system and the second node is associated with a second wireless communication system. The first type of message includes a first information element for identifying the second node and a second information element for specifying that the first frame is transmitted to initiate a request for simultaneous transmission by the first node and by the second node. The first frame is also received by a third node that is part of the first wireless communication system. The method further includes receiving from the third node a second frame that includes a second type of message.Type: GrantFiled: March 14, 2014Date of Patent: February 7, 2017Assignee: Nokia Technologies OyInventors: Fabiano de Sousa Chaves, Sayantan Choudhury, Fuad Mousse Abinader, Jr., Andre Mendes Cavalcante, Erika Portela Lopes de Almeida, Esa Tuomaala, Klaus F. Doppler, Mika Kasslin
