Resource allocation for LTE-direct broadcast of periodic vehicular safety messages

Research Report RR-13-290

Direct Device-to-Device (D2D) communications underlaying the cellular network are receiving increasing attention lately: LTE-A standard will adopt them for unicast proximity services. So far, no application has been envisioned for broadcast transmissions. In this work, we propose an eMBMSinspired mechanism to allocate a quasi-static pool of resources over multiple eNodeBs (eNBs) for D2D broadcast transmissions to take place. The mechanism does neither require any connection procedure with the eNB nor any additional network-side mobility management. Further, we propose multiple access according to a distributed TDMA-like scheme. We apply this concept to the periodic broadcast of CAMs / BSMs and show that the system's flexibility and extensibility make LTE-Direct a good complementary technology to DSRC for periodic vehicular safety communications.
