摘要： Techniques for performing peer discovery in a wireless network are described. A device may perform peer discovery to detect and identify other devices of interest. In an aspect, the device may perform peer discovery based on a hybrid mode that includes autonomous peer discovery and network-assisted peer discovery. In another aspect, the device may perform peer discovery based on a push mode and a pull mode. For the push mode, the device may occasionally transmit and/or receive a peer detection signal. For the pull mode, the device may transmit and/or receive a peer discovery request when triggered. In yet another aspect, the device may perform event-triggered peer discovery (e.g., for the pull mode). In yet another aspect, the device may perform peer discovery using both a downlink spectrum and an uplink spectrum. In yet another aspect, the device may transmit a peer detection signal in a manner to improve detection and/or increase payload.

摘要： Techniques for performing peer discovery to enable peer-to-peer (P2P) communication are disclosed. In an aspect, a proximity detection signal used for peer discovery may be generated based on one or more physical channels and/or signals used in a wireless network. In one design, a user equipment (UE) may generate a proximity detection signal occupying at least one resource block based on a SC-FDMA modulation technique. In another design, the UE may generate a proximity detection signal occupying at least one resource block based on an OFDMA modulation technique. The UE may generate SC-FDMA symbols or OFDMA symbols in different manners for different physical channels. In yet another design, the UE may generate a proximity detection signal including a primary synchronization signal and a secondary synchronization signal. For all designs, the UE may transmit the proximity detection signal to indicate its presence and to enable other UEs to detect the UE.

摘要： Techniques for supporting peer-to-peer (P2P) communication are disclosed. In an aspect, P2P communication may be supported with a symmetric waveform for a P2P downlink and a P2P uplink. In one design, a first UE generates a first signal based on a particular waveform (e.g., a downlink waveform or an uplink waveform for a wireless network) and transmits the first signal to a second UE for P2P communication. The first UE also receives a second signal generated by the second UE based on the particular waveform and transmitted to the first UE for P2P communication. In another aspect, a proximity detection signal may be transmitted in a portion of a subframe instead of the entire subframe. The remaining portion of the subframe may be used to transmit control information and/or other information to support P2P communication.

摘要： Techniques for performing network-assisted peer discovery to enable peer-to-peer (P2P) communication are described. In one design, a device registers with a network entity (e.g., a directory agent) so that the presence of the device and possibly other information about the device can be made known to the network entity. The network entity collects similar information from other devices. The device sends a request to the network entity, e.g., during or after registration. The request includes information used to match the device with other devices, e.g., information about service(s) provided by the device and/or service(s) requested by the device. The directory agent matches requests received from all devices, determines a match between the device and at least one other device, and sends a notification to perform peer discovery. The device performs peer discovery in response to receiving the notification from the network entity.

摘要： Techniques for establishing and maintaining peer-to-peer (P2P) communication are described. In an aspect, P2P communication on an unlicensed spectrum may be established and maintained with network assistance. In one design, a user equipment (UE) may communicate with a wide area network (WAN) to establish P2P communication with at least one other UE on a first frequency band that is not licensed to the WAN. For example, the UE may receive an assignment of at least one frequency channel in the first frequency band for P2P communication. The UE may then communicate peer-to-peer with the other UE(s) on the at least one frequency channel. The UE may also communicate with the WAN to maintain P2P communication with the other UE(s), e.g., to switch to another frequency channel if necessary.
