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.

Abstract: A communications device synchronizes itself with respect to an external reference signal, e.g., a GPS signal. The communications device detects timing reference signals, e.g., beacon signals, from a communications network. If the communications device determines that the network is not synchronized to the external timing reference signal, the communications device operates as a master timing control device. In various embodiments, when operating as a master timing control device the wireless communications device communicates time stamps, e.g., in beacon signals, which indicate a greater passage of time than the actual passage of time. When operating as a master timing control device the communications device transmits network timing reference signals at a higher rate than is being used by the network to seize control of network timing and become the master timing control device. The communications device drives the network timing to synchronize network timing to the external timing reference.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in which information indicating a partitioning between uplink and downlink resources is received, and communication with an access point to determine at least one of whether a downlink resource will be used for uplink or whether an uplink resource will be used for downlink is performed. Accordingly, a synchronous network may be provided where partitioning of uplink-downlink resources may be dynamically selected, which is more efficient than a synchronous network where uplink-downlink resource partitioning is global and semi-static.

Abstract: Methods and apparatus are described which increase the probability and/or frequency that devices with comparatively faster clocks in a network than other devices in the network will transmit beacon signals are described. As a result, devices with faster clocks will tend to drive system synchronization to convergence faster than if all devices transmitted beacons at the same rate, thus facilitating more reliable maintenance of system synchronization since the devices with faster clocks will tend to transmit more frequently.
