摘要： An improved mechanism is provided that facilitates transmission of small packets within an ad hoc peer-to-peer network. A small packet is identified to a receiver within a control channel so that its lower power can be considered in an interference management protocol implemented among local peer devices. In a traffic slot, a transmitter voluntarily backs down on the transmitter power as a smaller packet will require much lower signal-to-noise ratio. This will improve the signal energy per bit per noise power density for the transmission as well as minimize the interference caused to other wireless communications happening in the same spectrum.

摘要： In an ad hoc peer-to-peer communication network between wireless devices, a high priory first receiver device is configured to perform successive interference cancellation (SIC). The first receiver device receives a first transmission request from a first transmitter device indicating that the first transmitter device intends to transmit traffic to the first receiver device. Similarly, the first receiver device receives a second transmission request from an interferer second transmitter device. The first receiver device then determines a transmission rate cap for the interferer second transmitter device based on the signal strengths of the first and second transmission requests and sends it to the interferer second transmitter device. The transmission rate cap is a maximum rate at which the first receiver device can reliably decode traffic signals from the second transmitter device.

摘要： An ad hoc peer-to-peer network is provided in which a transmitter wireless terminal is configured to establish a peer-to-peer communication link with a receiver wireless terminal over a shared communication channel. The transmitter wireless terminal may scale its transmit power as a function of a channel gain for the communication channel between the transmitter and receiver wireless terminals. The scaled transmit power may be utilized by the transmitter and receiver wireless terminals to perform link scheduling over the communication channel. For instance, the scaled transmit power may be used by the transmitter wireless terminal to perform a transmitter yielding with other neighboring transmitter wireless terminals utilizing the shared communication channel. Similarly, the scaled transmit power may be used by the receiver wireless terminal to perform receiver yielding with other neighboring receiver wireless terminal utilizing the shared communication channel.

摘要： Systems and methodologies are described that facilitate paging within a peer-to-peer communication network. A first wireless terminal monitors the paging channel of a wide area network. When a second wireless terminal intends to establish a peer-to-peer connection with the first wireless terminal, the second wireless terminal generates a paging message and transfers the message to the WAN, which routes the paging message to a base station. The base station uses its paging channel to send a paging message to the target first wireless terminal. The paging message indicates to the target first wireless terminal that the second wireless terminal intends to establish a peer-to-peer connection with the first wireless terminal. The paging message may further include parameters to be used to establish the peer-to-peer connection. Upon reception of the paging message, the second wireless terminal sends a signal directly to the first wireless terminal to start the direct peer-to-peer communication.

摘要： A first device is configured to select and utilize a connection identifier (CID) for a peerto- peer communication connection between the first device and a second device in a wireless communications network. The CID is selected from a predetermined set of a plurality of CIDs. Prior to selecting the connection identifier, the first device monitors a CID broadcast channel to determine whether the CID is being utilized by other nearby connections. If it is determined that the CID is being utilized by another connection in the proximity, a different (unused) CID is selected. A transmission request is transmitted to the second device using a first transmission resource unit within a traffic management channel slot, the first transmission resource unit being determined as a function of the selected CID. The first device transmits traffic data to the second device in a traffic channel slot corresponding to the traffic management channel slot.

摘要： In an ad hoc peer-to-peer communications network, timing synchronization can be facilitated between nodes as a function of a received timing of nearby nodes, as well as a network timing. A first timing reference can be used to determine a symbol timing. A second signal that includes a second timing reference can be used to determine a difference between the symbol timing and the second timing reference. The difference can be used to adjust a symbol timing, which can be transmitted to nearby nodes. The first timing reference and the second timing reference can be received from different sources.

摘要： In an ad hoc peer-to-peer communications network, timing synchronization can be facilitated between two or more nodes based on respective timing adjustments. A sequence of timing synchronization time intervals can be determined based on a first timing reference received from a source. A symbol timing can be determined and included in a first signal transmitted during a dedicated time interval, which can be a chosen fraction of one of the timing synchronization time intervals. In the remaining portion of the time interval, such as a non-chosen fraction, a second signal that includes a second timing reference can be received. Based on the symbol timing and the second timing reference, a timing adjustment can be determined and timing of each node adjusted accordingly.

摘要： Methods and apparatus related to peer to peer communication networks are described. A peer to peer timing structure is implemented which includes recurring peer discovery intervals and traffic intervals. Some embodiments further include recurring paging intervals for peer to peer pages. A wireless communications device, supporting peer to peer communications and storing information defining the timing structure, determines a time reference point, facilitating a coarse level of synchronization with respect to the timing structure. The time reference point is determined based on a broadcast signal received from a communications device, e.g., a satellite, base station, or beacon signal transmitter. Multiple peer to peer wireless communications devices in a local vicinity thus obtain the same basic understanding as to the current relative point in time with respect to a common recurring peer to peer timing structure. Peer to peer timing synchronization is further refined based on received signals communicated between peers.

摘要： Methods and apparatus related to peer to peer communication networks are described. An active connection list is maintained by a wireless communications device supporting peer to peer communications. In various embodiments, the active connection identifier list being maintained is in addition to a list of discovered peers in the local vicinity. Paging signaling, e.g., peer to peer paging signaling, is used to establish active connections. Air link peer to peer traffic resources include traffic control resources and traffic data resources. A wireless communications device seeking to transmit on a traffic data resource transmits a traffic request signal on a traffic control resource. An active connection identifier is, in some embodiments, associated with a particular subset of traffic control resources. Thus, a wireless communications device monitors the portion or portions of the traffic control resource corresponding to its active connections for traffic request signals, but need not monitor other portions.
