Single-service or multi-service loss models for cloud radio access networks

Abstract

The cloud radio access network (C-RAN) is considered as a promising fifth generation (5G) network architecture. The C-RAN architecture implies that a number of distributed base stations (BSs) form a centralized network. Each BS is split into two components: the remote radio head (RRH), that includes the antennas and the baseband signal processing server, named baseband unit (BBU). The BBUs are centralized and implemented as virtualized BBUs (V-BBUs) by a computer data center. The pool of V-BBUs is connected to the RRHs via fronthaul links. We consider the C-RAN from the aspect of a loss system. In order for an arriving call to be served by the C-RAN, resource units should be allocated by the RRH (in which the call arrived) and the V-BBU pool (i.e., by the data center). The capacity of the RRH is expressed in radio resource units, while the capacity of the V-BBU pool is expressed in computational resource units. The RRHs are distinguished into homogeneous, when they have same capacity, ...
