SOFTWARE CONFIGURABLE DISTRIBUTED ANTENNA SYSTEM AND METHOD FOR REDUCING UPLINK NOISE
First Claim
1. A distributed antenna system including:
- a master unit including;
a downlink RF input operable to receive an RF input signal from a downlink port of a base station;
a first optical port; and
a second optical port;
a first remote unit coupled to the first optical port of the master unit, wherein the first remote unit comprises a downlink antenna port and a first uplink antenna port operable to receive a first RF uplink signal; and
a second remote unit coupled to the second optical port of the master unit, wherein the second remote unit comprises a downlink antenna port and a second uplink antenna port operable to receive a second RF uplink signal;
wherein the master unit is operable to;
transmit a first RF signal associated with the first RF uplink signal to a first uplink port of the base station; and
transmit a second RF signal associated with the second RF uplink signal to a second uplink port of the base station.

Abstract
A distributed antenna system includes a master unit including a downlink RF input operable to receive an RF input signal from a downlink port of a base station, a first optical port, and a second optical port. The distributed antenna system also includes a first remote unit coupled to the first optical port. The first remote unit comprises a downlink antenna port and a first uplink antenna port and a second remote unit coupled to the second optical port of the master unit. The second remote unit comprises a downlink antenna port and a second uplink antenna port. The master unit is operable to transmit a first RF signal associated with the first RF uplink signal to a first uplink port of the base station and transmit a second RF signal associated with the second RF uplink signal to a second uplink port of the base station.

18. A method of operating a distributed antenna system, the method comprising:
-
providing a processor; receiving a list of remote units, each of the remote units having an antenna port, wherein the list of remote units includes a number of non-diversity remote units; computing, for a sector, a number of diversity remote units and a number of non-diversity remote units; computing, using the processor, a percentage of the number of non-diversity remote units in the list of remote units; assigning, for each of the remote units, the antenna port to either a first uplink port of a master unit or a second uplink port of the master unit; transmitting the assignments to the remote units; receiving a first RF uplink signal at an antenna port of a first remote unit; receiving a second RF uplink signal at an antenna port of a second remote unit; transmitting an RF signal associated with the first RF uplink signal to the first uplink port of the master unit; and transmitting a second RF signal associated with the second RF uplink signal to the second uplink port of the master unit. - View Dependent Claims (19, 20, 21, 22)
