UPLINK PATH INTEGRITY DETECTION IN DISTRIBUTED ANTENNA SYSTEMS
First Claim
1. A distributed antenna system comprising:
- a remote antenna unit configured to communicate with wireless devices in a coverage area;
one or more additional remote antenna units configured to communicate with wireless devices in one or more additional coverage areas; and
a unit configured for communicating with the remote antenna unit and the one or more additional remote antenna units, the unit comprising a distributed antenna system controller that is configured to;
determine that an undesirable signal component having a signal power exceeding a threshold power is communicated via an uplink path from the remote antenna unit; and
minimize an impact of the undesirable signal component on the additional coverage areas of the one or more additional remote antenna units, wherein minimizing the impact comprises modifying the gain of the uplink path over which the undesirable signal component is communicated.

Abstract
Aspects and features are directed to an uplink integrity detection sub-system. In one aspect, a distributed antenna system is provided that includes a remote antenna unit that communicates with wireless devices in a coverage area, additional remote antenna units that communicate with wireless devices in additional coverage areas, and a unit that communicates with the remote antenna unit and the additional remote antenna units. The unit includes a distributed antenna system controller. The distributed antenna system controller can determine that an undesirable signal component having a power level exceeding a threshold power is communicated via an uplink path from the remote antenna unit. The distributed antenna system controller can also minimize an impact of the undesirable signal component on the additional coverage areas of the additional remote antenna units. Minimizing the impact can include modifying the gain of the uplink path over which the undesirable signal component is communicated.
