Abstract

A method for controlling C-RAN applicable for a C-RAN having a plurality of remote radio heads (RRH) and a baseband unit (BBU) includes the following steps: collecting a first uplink signal corresponding to a first user end device, determining a first estimated region based on a communication range of part of RRH's receiving the first uplink signal, setting N estimated coordinates in the first estimated region wherein N is larger than one, giving N moving directions to the N estimated coordinates, modifying the N estimated coordinates based on a maximum displacement and the N moving directions, and selecting at least one RRH to send a type-3 downlink packet to the first user end device based on the N modified estimated coordinates.
