Abstract:
Cellular vehicular to everything (C-V2X) is a feature which incorporates vehicular
communication to cellular network. V2X technology makes its way into the
cellular communication with 3gpp release 14. The introduction of C-V2X makes it
possible for nearby vehicles to propagate safety related information to avoid any
kind of collisions and traffic jam. C-V2X mainly utilizes the Sidelink channel
introduced in 3gpp release 12 for D2D connectivity for the direct communication.
But one of the main drawbacks of Sidelink channel is of having no feedback which
prompts the transmitting UE to send one blind HARQ retransmission after a
certain subframe to ensure the reliability of the system. In this paper we present
another retransmission scheme which is also based on the blind retransmission
but on the same subframe. Due to the choice of the same subframe to send
original and three HARQ retransmission, the latency becomes very much less than
the conventional retransmission scheme and also the reliability of the C-V2X
system is also sustained making it perfect retransmission scheme for C-V2X
communication which key requirements are low latency and high reliability
