Abstract

The invention relates to a network infrastructure and software defined remote radio head controller. The infrastructure comprises a fronthaul network, an RRH pool, a radio service chain (RSC). The RSC is coupled to the fronthaul network and the RRH pool for allocating the RRH resources. The RSC comprises an orchestrator and a remote radio head (RRH) controller. The orchestrator is used for receiving a radio resource request from the at least one C-RAN and converting the radio resource request into a RRH specific command. The RRH controller is used for slicing the RRH resources to create virtual RRHs according to the radio resource request. A SD-RRH controller divides the physical RRH resources into multiple slices and creates a softwareized virtual RRH using one or more SD-RRH slices such that each virtual RRH has a different configuration to accommodate different network services demand.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a network structure, a software-based remote radio head (RRH) controller and the remote radio head. Background technique [0002] In the past few decades, wireless communication networks have been widely used. Operators of wireless communication networks build more and more base stations and base transceiver stations (BTS) to meet the increasing demand for communication services in wireless communication networks. However, the cost of building a large number of base stations and base station receiving stations is high, and it becomes a problem for operators to reduce operating costs under the premise of meeting communication demand services. [0003] figure 1 It is a system structure diagram of a radio access network (radio access network, RAN) 10 in the prior art. The wireless access network 10 adopts fixed-point distributed base band units (distributed base band units, ...
