摘要： A protocol is provided that facilitates downlink concurrent peer-to-peer communications (within a time slot or traffic slot) between one device and many terminals as well as uplink concurrent peer-to-peer communications (within a time slot or traffic slot) between a plurality of terminals and one device. The concurrent peer-to-peer communications may take place within an ad hoc network of devices. To facilitate such operation, a time-frequency structure is provided within a control channel that allows the device and terminals to identify the peer-to-peer connections. This time-frequency structure also allows terminals to identify other sibling terminals that have a connection with the same device, thereby allowing to more efficiently performing interference mitigation. That is, sibling peer-to-peer connections with the same device may be treated different from other non-related peer-to-peer connects for purposes of interference mitigation in a wireless network.

摘要： Methods and apparatus related to scheduling and/or utilization of air link traffic resources are described. A connection identifier is associated with priority with regard to use of an air link resource, e.g., a peer to peer traffic segment which is in contention. A particular connection may acquire and hold one or multiple connection identifiers. In some embodiments, the priority associated with a particular connection identifier is intentionally varied in a set of traffic slots. In some such embodiments, there is priority randomization from slot to slot. In one such implementation there is a statistically uniform average priority between the different connection identifiers over the recurring structure. Such an implementation facilitates access to traffic segments to a wide range of users, yet allows for differentiation with regard to the amount of access as a function of the number of connection identifiers being held by a particular connection.

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： Methods and apparatus related to broadcasting data and interference management in a peer to peer wireless communications network are described. Scheduling of traffic air link resources is performed on a slot by slot basis in a decentralized manner. Wireless devices intending to broadcast traffic signals transmit broadcast request signals, sometimes alternatively referred to as broadcast indicator signals. A priority level is associated with each of the broadcast request signals. A receiver device intending to receive broadcast signals detects the broadcast request signals and makes an interference determination as to whether the higher priority broadcast traffic signal can be successfully recovered in the presence of lower priority broadcast traffic signals. If the determination is that the expected interference from the lower priority broadcast traffic is unacceptable, the receiver device generates and transmits an interference control signal communicating to the lower priority device a command or request not to broadcast.

摘要： Methods and apparatus for communicating information, e.g., queries and query responses, in a peer to peer communications network are described. Queries include, e.g., queries for a product, service, activity or activity partner. In some embodiments, a query channel is implemented and utilized. The implemented query channel structure is such that multiple query responses may be communicated corresponding to a single transmitted query. Various embodiments employ randomization in transmission segment selection by an individual communications device within a transmission block to decrease the likelihood of collisions. A communication device's access to the query channel is determined by the communications device itself. A communications device's decision as to whether or not to transmit and/or re-transmit a query is based on one or more of: its query transmission statistics, historical query channel loading information, and priority level information corresponding to the communications device.

摘要： Methods and apparatus related to a peer to peer wireless communications system supporting the association of multiple connection identifiers with a single connection between a pair of wireless terminals are described. A differentiated quality of service is supported by assigning different numbers of connection identifiers to different connections. The number of connection identifiers assigned to a wireless terminal pair for a connection is a function of one of: data rate, priority information, and quality of service information. Being allocated a higher number of connection identifiers results in being allocated a higher number of traffic transmission request resources, thus increasing the likelihood that the connection is permitted to use a traffic transmission segment. The allocation of connection identifiers is performed in a distributed manner in which handshake signaling occurs between a wireless terminal pair seeking to establish a connection, e.g., as part of a multi-step paging scheme.

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.
