SYSTEMS AND METHODS FOR A FRONTHAUL NETWORK

摘要

Various embodiments provide for systems, methods, or apparatuses that provide a fronthaul architecture that facilitates high fidelity and low latency communication between a radio processing unit, such as a baseband unit (BBU), which may be located a central office (CO), and a remote transceiver, which may comprise a remote radio head (RRH) or a remote radio unit (RRU), which may be located at remote cell site.

主权项

1. A method comprising:
receiving data from a radio processing unit; converting the data to a first radio frequency signal having a first frequency; pre-distorting a first intermediate signal to produce a pre-distorted radio frequency signal, the first intermediate signal being based on the first radio frequency signal; upconverting a second intermediate signal to a second radio frequency signal having a second frequency, the second intermediate signal being based on the pre-distorted radio frequency signal, the second frequency comprising an operating frequency of a radio transmitter operating at a remote location; amplifying a third intermediate signal to an amplified radio frequency signal having the second frequency, the third signal being based on the second radio frequency signal; and transmitting a fourth intermediate signal to the remote location, the fourth intermediate signal being based on the amplified radio frequency signal.
