GENERALIZED DIVISION FREE DUPLEXING TECHNIQUES FOR DECREASING RENDEVOUS TIME

摘要

A method and system using splitless duplexing (DFD) 98 to reduce the rendezvous time between two or more wireless perception devices 14, 16 is provided. The wireless perception devices 14 and 16 may opportunistically use the available frequency spectrum by communicating on available channels. For communication, the first device 14 can rendezvous with the second device 16 by sending a beaconing signal 64, 74, 84 on the frequency that the second device 16 is listening 96 . DFD technology 98 may enable each device 14, 16 to listen to a channel simultaneously transmitting (94) a beacon signal on the same channel. The rendezvous time is significantly reduced since the receiver canceling approach 20 used in the DFD technique does not need to separate the listening periods 62, 72 and 82 on the same channel and the sending periods 66, 76 and 86 Can be. Furthermore, embodiments include a general DFD (GDFD) approach in which the device listens to a broadband frequency, thereby further reducing the rendezvous time.;
