Abstract: Methods and devices are described for forwarding, managing, and/or detecting timing information for device-to-device discovery. Timing information may be received from a base station. A timing signal including the timing information may be transmitted. The timing signal may be transmitted during a sub-frame reserved for device-to-device discovery. Timing information for a base station may be transmitted to a user equipment (UE). Instructions to transmit a timing signal including the timing information during a sub-frame reserved for device-to-device discovery are also transmitted to the UE. Information indicating a timing of sub-frames reserved for device-to-device discovery by a neighboring base station may be received from a serving base station. A timing signal may be detected during at least one of the sub-frames reserved for device-to-device discovery. The timing signal may include timing information for the neighboring base station.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus allocates K blocks of subframes for WAN and peer-to-peer communications in a discovery period T and remaining subframes in the discovery period T for WAN communications and allocates a first set of subframes for peer discovery and a second set of subframes for the WAN communications in each block of the K blocks.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. A UE for wireless communication determines resource elements, within at least one resource block in a downlink subframe, that carry reference signals from a base station. The UE maps at least one of data or control information to the at least one resource block, punctures the at least one of the data or the control information from the resource elements determined to carry the reference signals, and transmits the at least one resource block to a second UE.
