Abstract: PROBLEM TO BE SOLVED: To provide methods and apparatus related to data broadcast and interference management in a peer-to-peer wireless communications network.SOLUTION: Scheduling of traffic air link resources is performed on a slot-by-slot basis in a decentralized manner. Wireless devices intending to transmit broadcast traffic signals transmit broadcast request signals. A receiver device detects the signals and makes an interference determination as to whether a higher priority broadcast traffic signal can be successfully recovered. 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.

Abstract: PROBLEM TO BE SOLVED: To provide an ad hoc peer-to-peer communication network between wireless devices where a high priority receiver device is configured to perform successive interference cancellation (SIC).SOLUTION: The first receiver device sends a first rate report signal and a second rate report signal, which indicate a first transmission rate and a second transmission rate, to a first transmitter device. A connection is established between the first transmitter device and the first receiver device, where the first receiver device is the intended receiver of traffic signals from the first transmitter device. The first receiver device receives a traffic signal in a subsequent traffic channel, the traffic signal including a first traffic signal from the first transmitter device having a first traffic transmission rate not exceeding the first transmission rate (608). The received traffic signal also includes a second traffic signal transmitted by an interfering second transmitter device having a second traffic transmission rate not exceeding the second transmission rate (610).

Abstract: PROBLEM TO BE SOLVED: To provide systems and methodologies that enable identification of peers based upon encoded signals during peer discovery in a peer-to-peer network.SOLUTION: Direct signaling that partitions a time-frequency resource into a number of segments is utilized to communicate an identifier within a peer discovery interval. A particular segment selected for transmission can signal a portion of the identifier, while the remainder can be signaled based upon tones communicated within the selected segment. Moreover, a subset of symbols within the resource is reserved (e.g., unused) to enable identification and/or correction of a timing offset (1002).

Abstract: PROBLEM TO BE SOLVED: To provide a protocol 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.SOLUTION: 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 devices and terminals to identify the peer-to-peer connections. This time-frequency structure also allows the terminals to identify other sibling terminals that have a connection with the same device, thereby allowing more efficient interference mitigation. That is, sibling peer-to-peer connections with the same device are not regarded as interferences in calculation of a signal-to-interference ratio of a certain kind of peer-to-peer connection.

Abstract: Methods, devices, and computer program products for transmitting and receiving discovery and paging messages are described herein. In one aspect, an apparatus operable in a wireless communication system includes a transmitter and receiver. The transmitter transmits a discovery packet during a first discovery interval of a plurality of discovery intervals. The discovery packet advertises a service provided in a wireless communications network, and the plurality of discovery intervals include recurring time intervals when a plurality of devices are configured to transmit and receive discovery packets. The receiver receives a paging packet from a first device during a first paging interval of a plurality of paging intervals. The paging packet indicates interest in the service, and the plurality of paging intervals include recurring time intervals when the plurality of devices are configured to transmit and receive paging packets. The plurality of paging intervals do not overlap the plurality of discovery intervals.
