Cloud-based radio access network for small cells
Abstract:
A wireless communications system is disclosed. The system comprises a baseband processing unit (BBU) pool including one or more baseband processing units (BBUs), and a plurality of remote radio heads (RRHs) connected to the BBU pool through a front-haul network, wherein the wireless communications system has a plurality of sectors, each of which includes one or more small cells, each of which is deployed by one of the plurality of RRHs, wherein a BBUs is mapped to two or more RRHs in a sector in a one-to-many configuration, and a BBU is mapped to a single RRH in a sector in a one-to-one configuration, and wherein a combination of the one-to-one configuration and the one-to-many configuration is applied to each sector. Other systems, apparatuses, and methods also are disclosed.
