摘要： Methods and apparatus related to packet fragmentation and reconstruction are described. A sequence of bits is generated including at least one header and at least partial packet payload prior to a determination of the actual data rate to be used in a communications segment. In some embodiments, the generated sequence of bits corresponds to a prepared information bit stream for a best case scenario in which the highest data rate is selected for segment. Various embodiments allow for the selection of the data rate to be used for the communications segment to be delayed until just prior to the transmission. Thus the selection of the data rate for the communications segment, and thus the segment capacity, can be based on more current channel condition information than would otherwise be possible if the communications device needed to know the data rate for the segment before performing header and packet fragmentation operations.

摘要： Aspects describe different multiple antenna techniques that can be utilized in a peer-to-peer network based on a network congestion level. A MIMO scheme where a transmitter sends to a receiver multiple spatial streams at substantially the same time in the same traffic segment can be utilized when network congestion level is low. A receiver beam forming scheme where transmitter sends a single stream in a traffic segment and receiver uses multiple receive antennas to maximize signal to noise ratio can be utilized when network congestion level is high. The connection pair (transmitter and receiver) occupy more control resources in the MIMO scheme than the receiver beam forming scheme. The decision related to which technique to utilize can be made at about the same time as a communication is initiated. Further, if network conditions change during a communication, the antenna technique that is utilized can be switched to a different technique during the communication exchange.

摘要： Methods and apparatus related to supporting rapid synchronization between groups of wireless communications devices are described. Described methods and apparatus are well suited for use in peer to peer wireless communications systems in which a plurality of ad hoc peer to peer networks may be formed, each ad hoc network operating with its own notion of time. As two groups of devices, having different notions of time, come within proximity of one another, a wireless communications device of a first group detects the presence of a member of a second group. The wireless device determines that network timing re-synchronization is to be performed by one of the first and second groups and transmits a re-synchronization alert signal on a dedicated resource. Subsequently, the wireless device transmits a timing synchronization signal in accordance with new timing. Intended devices, which detect the alert signal and timing synchronization signal, adjust their internal timing.

摘要： A wireless terminal detects timing signals from different local timing signal sources. The wireless terminal selects from the plurality of detected timing signal sources two timing signal sources in accordance with a predetermined timing signal source priority ordering. In some embodiments, the wireless terminal intentionally selects two timing signal sources which are not synchronized with respect to one another. The wireless terminal determines a first set of peer communications time intervals corresponding to a first selected timing signal source and a second set of peer communications time intervals corresponding to a second selected timing signal source. The wireless terminal transmits a peer to peer signal, e.g., a peer discovery signal, during at least one of the first set of peer communications time intervals. The wireless terminal transmits a peer to peer signal, e.g., a peer discovery signal, during at least one of the second set of peer communications time intervals.

摘要： To maintain a synchronized wireless peer group, timing signals may be periodically transmitted by one or more devices in the wireless peer group. These periodic timing signals may be transmitted by different wireless devices in the peer group, distributing (sharing) the transmit power burden among the different wireless devices, increasing the useful operation time of the individual wireless devices. Similarly, the wireless peer group may monitor for timing signals received from devices that are not part of the wireless peer group. This monitoring burden may also be distributed (shared) among the devices in the peer group allowing for a greater sleep time for individual wireless devices, increasing the useful operation time of the individual wireless devices.
