Abstract

Methods and apparatus are described for efficiently suppressing transmission of signals from devices which are using a first protocol in order to allow the frequency spectrum being used by devices using the first protocol to be used briefly for communication between devices using an alternative communications protocol. In some embodiments the first protocol is WiFi and the alternative signaling protocol is a non WiFi peer to peer communications protocol. A wireless communications device e.g. a peer to peer wireless communications device generates a signal suppression utility metric (SSUM). The signal suppression utility metric provides an indication of how useful transmitting a transmission suppression signal e.g. a S CTS signal which may be a CTS to self signal will be at a given point in time. The wireless communications device decides whether or not to transmit a transmission suppression signal as a function of the signal suppression utility metric.
