Method and system for soft frequency reuse in a distributed antenna system
First Claim
1. A method for routing and switching operator RF signals, the method comprising:
- providing a plurality of Digital Remote Units (DRUs), each configured to receive one or more downlink radio frequencies and to transmit one or more uplink radio frequencies; and
providing at least one Digital Access Unit (DAU) configured to communicate with at least one of the plurality of DRUs,wherein a first DRU in a first cell is operable to communicate using a first set of frequencies characterized by a first frequency band over a first geographic footprint,wherein a plurality of second DRUs in the first cell are operable to communicate using a second set of frequencies characterized by a second frequency band different from the first frequency band over a second geographic footprint surrounding the first geographic footprint,wherein a third DRU in a second cell is operable to communicate using the first set of frequencies over a third geographic footprint, andwherein a plurality of fourth DRUs in the second cell are operable to communicate using a third set of frequencies characterized by a third frequency band different from the first frequency band over a fourth geographical footprint surrounding the third geographical footprint.

Abstract
A method for routing and switching operator RF signals includes providing one or more Digital Remote Units (DRUs) and providing at least one Digital Access Unit (DAU) configured to communicate with at least one of the one or more DRUs. A first DRU is operable to communicate using a first set of frequencies characterized by a first frequency band over a first geographic footprint and a second set of frequencies characterized by a second frequency band different from the first frequency band over a second geographic footprint including and surrounding the first geographic footprint. A second DRU is operable to communicate using the first set of frequencies over a third geographical footprint and a third set of frequencies characterized by a third frequency band different from the first frequency band and the second frequency band over a fourth geographic footprint including and surrounding the third geographic footprint.

7. A method of distributing communications frequencies, the method comprising:
-
providing a set of communications units; transmitting and receiving, from a first communications unit of the set of communications units, a first set of frequencies characterized by a first frequency band over a first geographic footprint; transmitting and receiving, from a plurality of second communications units of the set of communications units, a second set of frequencies characterized by a second frequency band different from the first frequency band over a second geographic footprint larger than and at least partially surrounding the first geographic footprint; transmitting and receiving, from a third communications unit of the set of communications units, a third set of frequencies including one or more frequencies in the first frequency band over a third geographical footprint; and transmitting and receiving, from a plurality of fourth communications units of the set of communications units, a fourth set of frequencies characterized by a third frequency band over a fourth geographical footprint larger than and at least partially surrounding the third geographical footprint. - View Dependent Claims (8, 9, 10, 11, 13)
