Abstract
A system may include a base station and a remote radio head (“RRH”). The base station may receive digital data streams destined for a user device, and generate a first set of modulated signals. The modulated signals may each be based on a different one of the digital data streams. The generated first set of modulated signals may be modulated within a first carrier frequency band. The base station may output the first set of modulated signals to the RRH. The RRH may generate a second set of modulated signals based on the first set of modulated signals. The second set of modulated signals being modulated within a second carrier frequency band, and may output the second set of modulated signals to the user device.

A method, comprising:
- receiving, by a remote radio head (“RRH”), from a base station of a cellular network, a first set of modulated signals, each of the modulated signals being based on a different data stream, of a plurality of data streams received by the base station, the first set of modulated signals being modulated within a first carrier frequency band;
- generating, by the RRH, a second set of modulated signals based on the first set of modulated signals, the second set of modulated signals being modulated within a second carrier frequency band, the second carrier frequency band being different from the first carrier frequency band;
- and
- outputting, by the RRH, the second set of modulated signals to the user device.
A system, comprising:
- a base station of a cellular communications network;
- and
- a remote radio head (“RRH”) associated with the base station,
- the base station being to:
- receive a plurality of digital data streams destined for a user device,
- generate a first set of modulated signals, each of the modulated signals being based on a different one of the digital data streams, the generated first set of modulated signals being modulated within a first carrier frequency band, and
- output the first set of modulated signals to the remote radio head RRH;

- output the second set of modulated signals to the user device.
A computer-readable medium, comprising:
- a plurality of computer-executable instructions, which, when executed by one or more processors, cause the one or more processors to:
- receive a plurality of digital data streams destined for a user device,
- generate a first set of modulated signals, each of the modulated signals being based on a different one of the digital data streams, the generated first set of modulated signals being modulated within a first set of frequencies,
- generate a second set of modulated signals, the second set of modulated signals including a plurality of subsets of modulated signals, each subset being associated with a particular modulated signal, of the first set of modulated signals, wherein each modulated signal of a particular subset of modulated signals is associated with a different phase than other modulated signals of the particular subset,
- output the second set of modulated signals to a remote radio head (“RRH”);
- and
- receive, by the RRH, the second set of modulated signals;
