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, a device performs peer discovery based on trigger events. In one design, the device detects an event triggering peer discovery, which may be an application becoming active on the device, a change in the position of the device, the device being turned on, etc. The device performs peer discovery based on detection of the event triggering peer discovery. In one design, the device starts peer discovery in response to detecting the trigger event. In another design, the device changes at least one characteristic (e.g., the periodicity) of peer discovery in response to detecting the trigger event. In another design, a device determines an application becoming active on the device. The device transmits a query (e.g., in a proximity detection signal) to request for a service from a peer device to support the application.

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： Systems and methodologies are described that facilitate establishing a forward link acknowledgement channel and transmitting acknowledgment signals thereupon. In particular, the signals can be spread within contiguous channel clusters in a tile where the signals in the cluster are mutually orthogonal to one another. Additionally, the signals can be multiplexed over a plurality of frequency regions. In this regard, the acknowledgment signals are diverse with respect to frequency and interference; moreover, the signals can be received and decoded even where one of the channels experiences high interference. Furthermore, the acknowledgement signals can also communicate a channel deassignment value, which allows devices to utilize persistent channels in communicating data to one another.
