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： 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： 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.

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.
