Abstract
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. The second type of message identifies the second node and specifies, based on a measurement performed by the third node on the first frame and a measurement performed by the third node on a third frame transmitted by the second node, whether the request for simultaneous transmission is accepted or is not accepted by the third node. The method further includes trans…
