Abstract

In a method of device-to-device communication, a user device initially sends an emergency message repeatedly at a first repeating frequency. When a specified number acknowledgement (ACK) messages are received, the user device sends the emergency message repeatedly at a reduced repeating frequency. The repeating frequency may be further reduced when more ACK messages are received.
