1. A method, comprising:
facilitating, by a system comprising a processor, receiving a message from a user equipment, wherein the message comprises signal information describing a detection of a signal of a carrier of a base station equipment, and wherein the signal was detected while the user equipment was in an idle mode at a first location;
identifying, by the system, a second location of the base station equipment corresponding to a time when the signal was transmitted, wherein the second location is different from the first location;
based on the first location, the second location, and the signal information, estimating, by the system, a path loss of the carrier at the first location, wherein the path loss comprises a first downlink path loss; and
estimating, by the system, an uplink path loss for the first location by comparing the first downlink path loss to a second downlink path loss measurement from the base station equipment at the first location, by a second user equipment that collected the second downlink path loss measurement during an active mode communications connection.
