摘要： A method of operating a first wireless device includes receiving a grant from a base station for peer-to-peer communication with a second wireless device using time-frequency resources utilized by a third wireless device for WWAN communication with the base station. In addition, the method includes receiving a transmit power for the peer-to-peer communication with the grant. The transmit power is determined based on an interference that can be caused to transmissions received by the base station from the third wireless device. Furthermore, the method includes communicating with the second wireless device at a power less than or equal to the received transmit power using peer-to-peer communication on the time-frequency resources.

摘要： A wireless communications system supports both cellular communications and direct peer to peer communications. The cellular communications use FDD downlink and uplink bands for control and traffic signaling. An access point employs control over direct peer to peer communications. Peer to peer mode control signals from the access point are transmitted to wireless terminals using the FDD cellular downlink band. Peer to peer mode control signals from wireless terminals are transmitted to an access point using the FDD cellular uplink band. Peer to peer traffic signals between wireless terminals are communicated using a TDD band. In one embodiment, the access point communicates priority information to peer to peer network wireless terminals, and the wireless terminals make peer to peer traffic transmission decisions in a decentralized manner using the received priority information. In another embodiment, the access point directly schedules peer to peer traffic in the peer to peer network.

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： Various methods and apparatus are directed to communicating peer discovery information in an efficient manner. A wireless device which has received peer discovery information from multiple peer devices in its vicinity combines received peer discovery information and transmits a signal communicating the combined information. In some embodiments, the combining includes performing a linear combination. The transmitted signal including the combined peer discovery information corresponding to multiple devices facilitates the recovery of peer discovery information by peer devices which may be out of direct peer to peer communications range to one of the devices whose information was used to produce the combined signal. Different peer devices may be able to recover different peer discovery information from the same combined signal. Thus the wireless device may effectively relay a first peer discovery message to one peer device and a second peer discovery message to another peer device via the same combined signal.

摘要： Methods and apparatus for wireless communications in regional networks, e.g., ad hoc peer to peer networks, are described. Wireless communications devices transmit and monitor for presence indicator signals broadcast from other peer communications devices in its local vicinity. A wireless communications device maintains a list of discovered devices in its vicinity. A first wireless communications device transmits a paging signal directly over an airlink to a second communications device, which is on its list and to which it desires to send data units, e.g., user data in a peer to peer traffic segment. In response to a received paging response signal from the second device, the first device transmits data units, intended for the second device, to a third device, which acts as an intermediary node. The power level for the data unit signal is controlled to be lower than the power level used for the paging signal. FIG. 4
