    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 unified, low-complexity processing (e.g., user separation and noise estimation) of a control channel. One or more UEs can respectively transmit one or more control signals, which are multiplexed on a control channel and a base station can receive a control channel signal that includes the one or more control signals. The base station, in a single pass, can separate the control signals by matching the control channel signal with a base sequence and translating the matched signal to a time-domain representation. In the time-domain representation, each control signal resides at a different tap. Further, the base station can identify taps of the time-domain representation corresponding to an unused cyclic shift or orthogonal cover sequence. Such taps can be employed to generate a noise and/or interference estimate.

    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： Blind interference cancellation is described for wireless networks in which a subject base station or cancellation apparatus obtains semi-static information for at least one of its neighboring cells. The base station measures the noise level of each of the neighboring cells based on samples it takes of uplink transmissions in each of the neighboring cells. The neighboring cells are then ranked for interference cancellation based on their relative noise levels. The base station performs discontinuous transmission (DTX) detection to identify at least one interfering user equipment (UE) in the neighboring cell and cancels interference attributable to those identified interfering UEs. The DTX detection and cancellation are then repeated for the remaining neighboring cells in the order they are ranked.
