Enhanced C-RAN Using D2D Network

IEEE Communications Magazine, 2017
With the surge in smartphone sensing, wireless networking, and mobile social networking techniques, mobile crowdsensing (MCS) has become a promising paradigm for 5G networks. An MCS system's service quality heavily depends on the platform, which brings the users under a common cloud with very low delay.

A Two-Timescale Approach for Network Slicing in C-RAN

IEEE Transactions on Vehicular Technology, 2020
Network slicing is a promising technique for cloud radio access networks (C-RANs). It enables multiple tenants (i.e., service providers) to reserve resources from an infrastructure provider.

CPU-MPU partitioning for C-RAN applications

7th International Conference on Communications and Networking in China, 2012
This paper discusses methods for employing co-processors for off-loading the general purpose CPU in a cloud RAN application. A new concept, termed Modem Processing Unit (MPU) is introduced, in which the data path is offloaded from the CPU. The MPU concept provides benefits in overall throughput and power consumption, and alleviates the data transfer ...
