Device discovery using distributed random access for device to device communication
A fast device discovery protocol with a high success rate for device-to-device (D2D) communication in LTE-A networks is proposed. With the proposed protocol, device discovery is done by monitoring a randomly transmitted beacon from other devices within a pre-defined period. In one embodiment, an eNB receives scheduling requests from D2D UEs and in response allocates a distributed uplink resource for random access of beacon transmission by the D2D UEs. The distributed resource is dynamically allocated based on the number of requesting D2D UEs, a discovery period, and a target discovery probability to minimize the required resource.
