  2. Motion: PHY Discovery Signal Byung-Jae Kwak et al., ETRI • Discovery signal is transmitted via UWB, OFDM, or DFT-S OFDM . • DFT-S OFDM or OFDM • discovery information is mapped onto discovery resource blocks (DRBs). The preambles are included (not shown). • A Discovery Resource Block comprises one or multiple of time resources or time and frequency resources. • UWB (TBD) • Fairness • PDs

  3. Motion: MAC Discovery IDs Byung-Jae Kwak et al., ETRI • For the purpose of discovery of PDs, the discovery information may represent one or more of the following IDs such as Device ID, Device Group ID, Application type ID, Application-specific ID, Application-specific user ID, and Application-specific group ID. • The discovery IDs are generated from the higher layer.

  4. Motion: MAC Discovery Type Byung-Jae Kwak et al., ETRI The Discovery type is defined by the higher layer. The MAC messages should support at least the following discovery types: • Advertisement: In Advertisement type discovery, a PD broadcasts its own discovery information and does not expect responses. • Publish/Subscribe: In Publish/Subscribe type discovery, a PD broadcasts its own discovery information and expects responses from PDs that have discovered the broadcast message(s). • Query/Reply: In Query/Reply type discovery, a PD broadcasts the discovery information of the PD or PDs being queried and expects a response or responses from the PD or PDs, accordingly.

  5. Motion: MAC Discovery Messages Byung-Jae Kwak et al., ETRI MAC should support the following discovery message type: • Discovery Request message • Discovery Response message

  6. Motion: MAC Discovery Procedures Byung-Jae Kwak et al., ETRI The discovery procedure should support mechanisms to ensure privacy that a PD is not tracked. The discovery procedure should support protection of identity from impersonation.
