Abstract:
A method includes: receiving MIMO channel signals at original MIMO frequency from signal source(s) at master unit of DAS, set(s) of the MIMO channel signals including first MIMO channel signal and second MIMO channel signal; generating local oscillator signal at master unit; frequency converting first MIMO channel signal(s) and second MIMO channel signal(s) from original MIMO frequency to different frequency different from first legacy service frequency band using local oscillator signal at master unit; combining first MIMO channel signal, second MIMO channel signal, and local oscillator signal into combined signal at master unit; transmitting combined signal across optical link to remote unit; processing first MIMO channel signal and/or second MIMO channel signal at remote unit; and frequency converting converted MIMO channel signal(s) from different frequency different from first legacy service frequency band back to original MIMO frequency for transmission over antenna(s).

Claim (Index 16):
A method comprising:\n receiving a plurality of sets of multiple input multiple output (MIMO) channel signals at respective original first and second MIMO frequencies at a master unit of a distributed antenna system, each set of the MIMO channel signals including at least a first MIMO channel signal and a second MIMO channel signal; generating a local oscillator signal at the master unit; frequency converting the at least one of the first MIMO channel signals from the original first MIMO frequency to a first different frequency different from a first legacy service frequency band using the local oscillator signal at the master unit; frequency converting the at least one of the second MIMO channel signals from the original second MIMO frequency to a second different frequency different from a second legacy service frequency band based on the local oscillator signal at the master unit; combining the at least one of the first MIMO channel signals, the at least one of the second MIMO channel signals, and the local oscillator signal at the master unit; transmitting the combined signal across an optical link to a remote unit; processing the at least one converted first MIMO channel signal at the remote unit; processing the at least one converted second MIMO channel signal at the remote unit; frequency converting the at least one converted first MIMO channel signal from the first different frequency different from the first legacy service frequency band and back to the first MIMO frequency for transmission over the at least one antenna; and frequency converting the at least one converted second MIMO channel signal from the second different frequency different from the second legacy service frequency band and back to the second MIMO frequency for transmission over at least one antenna.
