Abstract:
Cloud radio access networks (C-RANs) have been proposed to provide high energy-spectral efficiency and high data rate at low cost. In this paper, we introduce a novel C-RAN deployment scheme that is complementary to traditional cellular radio networks, where the key idea is to install the remote radio heads (RRHs) of the C-RAN in a load-balanced way to lighten the transmission burden of the fronthauls between the RRHs and the centralized baseband unit (BBU) pool, and activate the RRHs on demand to reduce system-wide energy consumption. Numerical results show that our proposed method performs well in practical scenarios. It provides QoS-guaranteed performance with relatively low capital expenditure (CAPEX) and operating expenditure (OPEX).
