Method and system for soft frequency reuse in a distributed antenna system
First Claim
1. A communication system comprising:
- a host unit;
at least one first remote unit coupled to the host unit and operable to transmit and receive radio frequency (RF) communications in a first cell, wherein the at least one first remote unit is configured to communicate using a first frequency band over a first geographic region corresponding to a portion of the first cell, wherein the at least one first remote unit is configured to communicate using a second frequency band over a second geographic region corresponding to an entirety of the first cell, and wherein the first frequency band is distinct from the second frequency band; and
at least one second remote unit coupled to the host unit and operable to transmit and receive RF communications in a second cell, wherein the at least one second remote unit is configured to communicate using a third frequency band over a third geographic region corresponding to a portion of the second cell, wherein the at least one second remote unit is configured to communicate using a fourth frequency band over a fourth geographic region corresponding to an entirety of the second cell, and wherein the third frequency band is distinct from the fourth frequency band.

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.

11. A method comprising:
-
communicating at least one signal from a host unit to at least one first remote unit and at least one second remote unit; broadcasting, from the at least one first remote unit, radio frequency communications using a first frequency band over a first geographic region corresponding to a portion of a first cell; broadcasting, from the at least one first remote unit, radio frequency communications using a second frequency band over a second geographic region corresponding to an entirety of the first cell, wherein the first frequency band is distinct from the second frequency band; broadcasting, from the at least one second remote unit, radio frequency communications using a third frequency band over a third geographic region corresponding to a portion of a second cell; and broadcasting, from the at least one second remote unit, radio frequency communications using a fourth frequency band over a fourth geographic region corresponding to an entirety of the second cell, wherein the third frequency band is distinct from the fourth frequency band. - View Dependent Claims (12, 13, 14, 15, 16, 17)
