    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 supporting peer-to-peer (P2P) communication and wide area network (WAN) communication are disclosed. In one aspect, P2P communication may be supported on an uplink spectrum. A user equipment (UE) may communicate (i) with a base station on both a downlink spectrum and an uplink spectrum for WAN communication and (ii) with another UE on only the uplink spectrum for P2P communication. In another aspect, P2P communication may be supported by time division multiplexing the downlink and uplink (or transmit and receive links) for two UEs. In yet another aspect, WAN communication and P2P communication may be time division multiplexed, so that both can be concurrently supported by a UE. In yet another aspect, transmission gaps may be provided between WAN transmissions and P2P transmissions in order to avoid interference between these transmissions.
