Self-optimizing distributed antenna system using soft frequency reuse
DC CAFCFirst Claim
1. A method of determining a transmission power of a digital remote unit (DRU) in a distributed antenna system (DAS), the method comprising:
- a) setting a transmission power level for the DRU;
b) determining a key performance indicator related to a number of satisfied users at the transmission power;
c) iteratively adjusting a transmission power level for the DRU to increase the key performance indicator related to the number of satisfied users; and
d) setting the transmission power level for the DRU at an iterated power level.

Abstract
A method of determining a carrier power in a communications system including a processor includes a) setting a power differential between a reference carrier and one or more carriers, b) measuring a number of satisfied users at the power differential, and c) measuring a capacity for the satisfied users at the power differential. The method also includes d) increasing the power differential by a predetermined amount and e) determining, using the processor, that the number of satisfied users at the increased power differential is greater than or equal to the number of satisfied users at the power differential. The method further includes f) repeating a)-c) and g) setting the carrier power at an iterated power level.

13. A distributed antenna system comprising:
-
a digital access unit (DAU) communicatively coupled to a signal source, wherein the DAU is operable to receive wireless resources associated with one or more signal source sectors; a central DRU coupled to the DAU and assigned to a specific sector of the one or more signal source sectors; and one or more DRUs communicatively coupled to the central DRU and assigned to the specific sector, and wherein, the central DRU is assigned a full-reused frequency associated with the specific sector, and wherein each of the one or more DRUs are assigned a particular frequency partition of the full-reused frequency. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
