Abstract: Methods, apparatuses, and computer-readable mediums for wireless communication are disclosed by the present disclosure. In an example, a host device may determine a pool of preconfigured resources for discovery. The preconfigured resources are designated for one or more of: a discovery preamble, a query signal, a discovery message, and a random access preamble. The host device may transmit the discovery preamble on one or more resources designated for the discovery preamble. A client device may receive the discovery preamble and determine that the client device is interested in receiving information regarding the host device. The client device may transmit a query signal if interested. The host device may determine whether the query signal is received on a resource designated for the query signal in response to the discovery preamble. The host device may transmit a discovery message in response to receiving the query signal.

Abstract: Certain aspects of the present disclosure provide techniques for hierarchical communication for device-to-device (D2D) communications. In certain aspects, a method generally includes determining user equipment (UE) data comprising at least one of one or more parameters about the UE, one or more parameters about objects near the UE, or raw sensor data. The method further includes determining a first level for transmitting a first portion of the UE data based on content of the first portion of the UE data. The method further includes determining a first modulation coding scheme associated with the first level based on a mapping of a plurality of levels to a plurality of modulation coding schemes. The method further includes encoding the first portion of the UE data using the first modulation coding scheme and transmitting the first portion of the UE data from the UE to at least one second UE directly.

Abstract: An effective way for the cellular device-to-device communication and the short range communication to share a set of channels for communication is desired. The apparatus may be a user equipment (UE). The apparatus determines a priority level of each channel of a plurality of channels. The apparatus determines whether a first channel of the plurality of channels, the first channel having a highest priority level, is occupied by short range wireless communication. If the first channel is occupied by the short range wireless communication, the apparatus determines availability of one or more remaining channels of the plurality of channels for a cellular device-to-device (D2D) communication, where the one or more remaining channels are different from the first channel.

Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. The apparatus may be a UE. The UE transmits a message to a base station. The message includes a status of the UE. The UE receives a DCI message from the base station based on the status. The DCI message includes transmit power control information for D2D communications. The transmit power control information indicates whether the UE can transmit at an allowed transmit power. The UE transmits data based on the transmit power control information received in the DCI message.
