Estimating success rate of direct data transmissions between mobile devices in a wireless network

摘要

In a method for estimating success rate of direct data transmissions between mobile devices in a wireless network, a first group of mobile devices is selected from a plurality of mobile devices in the network. The mobile devices in the first group transmit at least one predefined test message to at least another mobile device in the network. Each mobile device to which a test message has been sent attempts to decode the test messages, and measures the number of successfully decoded messages. An estimate of a success rate is generated based on the number of successfully decoded messages and allocating resources for transmitting messages directly between the mobile devices may be based on the success rate in order to optimise the success rate. A test message may be included within a scheduling assignment message for indicating parameters associated with a subsequent data transmission. The mobile devices may be vehicle-based employing vehicle-to-vehicle (V2V) transmissions using LTE-direct LTE-D messages sent between devices over the PC-5 interface, e.g. the sidelink.
