Abstract
Description
technical field
[0001] The present invention relates to the field of communication technology, in particular to a method, device and system for sending signals. Background technique
[0002] In the mobile communication system, the C-RAN (Cloud Radio Access Network, cloud-based deployment of access network) system has become a technology that manufacturers and operators generally pay attention to. It is a larger-scale wireless access network that applies cloud computing technology. into the system. C-RAN centralizes the BBU (Base-band Unit, baseband processing unit) of multiple base stations through optical fiber or optical transmission network, and pulls the RRU (Radio Remote Unit, radio frequency remote unit) far away for signal coverage. Compared with the traditional deployment method, this deployment method has the advantages of reducing the cost of building a station, saving energy, facilitating maintenance, and improving the spectrum efficiency of joint transmission. ...
