Abstract
A wireless access system includes a baseband processing unit pool, an optical network unit and a remote radio head. The BBU pool may be connected to one or more ONUs, each of the ONUs may be connected to one or more RRHs, and the connection between each of the ONUs and the one or more RRHs may be implemented using a twisted pair. Embodiments can provide access, convergence and transport with a very large capacity from indoor antenna units to a centralized BBU as well as an easy installation, and thus they are cost economical for a large scale deployment of indoor wireless access. Furthermore, advanced wireless technologies, such as large scale MIMO and CoMP, can be supported.
Claims21
A wireless access system, comprising a baseband processing unit (BBU) pool, an optical network unit (ONU), and a remote radio head (RRH), the BBU pool being connected to one or more ONUs, each of the ONUs being connected to one or more RRHs, a connection between each of the ONUs and the one or more RRHs being implemented using a twisted pair.
-14. (canceled)
-17. (canceled)
A remote radio head (RRH), comprising:
- one or more antenna ports configured to receive signals from respective antennas;
- a down converting unit configured to down convert the signals of the one or more antenna ports;
- and
- a twisted pair corresponding to each of the antenna ports configured to transport the down converted signals to an output port.
-22. (canceled)
An optical network unit (ONU), comprising:
- an input port configured to receive a signal via a twisted pair;
- a processing unit configured to process the received signal;
- and
- an output port configured to output the processed signal to an optical fiber and passive optical network (PON) architecture for transportation.
-25. (canceled)
An optical line terminal (OLT), comprising:
- an input port configured to receive an optical signal via an optical fiber and passive optical network (PON) architecture, the optical signal being generated based on a signal transported through a twisted pair;
- a processing unit configured to process the received optical signal to be an electrical signal;
- and
- an output port configured to output the electrical signal.
(canceled)
A baseband processing unit (BBU) pool, comprising:
- a compensating unit configured to compensate for crosstalk of a signal during transportation through a twisted pair.
