Abstract
Enabling ultra-reliable low-latency communications in 5G wireless networks creates challenging design requirements, particularly on the air interface. The stringent latency and reliability targets require enhancements at different layers of the protocol stack. On the other hand, the Parallel Redundancy Protocol, wherein each data packet is duplicated and transmitted concurrently over two independent networks, provides a simple solution for improving reliability and reducing latency in wireless networks. PRP can be realized in cellular networks through the dual connectivity solution. Recently, 3GPP has introduced packet duplication functionality in 5G wireless networks. To this end, this article provides an overview of the packet duplication functionality in 5G in light of recent developments within 3GPP, and also highlights the related technical challenges.
