    Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus is configured to transmit a first SA information in a first subframe. The apparatus is further configured to transmit a first data in the first subframe. The apparatus is configured to transmit a second SA information in a second subframe. The apparatus is also configured to transmit a second data in the second subframe. The first SA information includes information on the first data and the second data. The second SA information includes information on the second data.

    Abstract: Improvement in co-existence of the LTE device-to-device communication with another device-to-device communication method is desired. The apparatus selects a countdown number within a size of a contention window including a plurality of slots before a target subframe. The apparatus determines whether each slot of the plurality of slots is idle or utilized while waiting for the target subframe. The apparatus counts down the countdown number during each of the determined idle slots. The apparatus determines whether the countdown number has reached a threshold number before the target subframe. The apparatus performs, when the countdown number is determined to have reached the threshold number, one of: deferring from transmitting until the target subframe, or transmitting a CUBS until a next subframe or the target subframe.

    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 receives discovery resource information from a base station, sends a discovery signal based on the discovery resource information, and receives from at least one user equipment (UE) a request for relaying with the base station based on the discovery signal. The apparatus may also receive a discovery signal from a relay, and send to the relay a request for relaying with a base station based on the discovery signal. The apparatus may further receive a discovery signal from each of a plurality of relays, determine to select one of the plurality of relays based on the discovery signal from each relay, and send to a selected relay a request for relaying with a base station based on the discovery signal when one of the plurality of relays is determined to be selected.
