摘要: Cloud radio access network (C-RAN) is regarded as a promising solution of future mobile communication infrastructures. The key character C-RAN migrating conventional distributed base station functionalities into centralized cloud baseband unit (BBU) pool, which consists many software defined virtual machines (VMs). In this paper, we take the joint consideration VM activation in BBU pool and transmission (JT) coordinated remote heads (RRHs) cluster to minimize system cost C-RAN, such that delay constraint can be satisfied. We propose two different approaches solve problem, i.e., integer search (IS) approach optimization (JO) approach. Simulation results suggest our proposed algorithm more cost-effective than benchmark algorithms.
