Abstract
A radio access network element, such as a remote radio head (RRH) comprises at least one processor and at least one memory. The at least one memory stores instructions that, when executed by the at least one processor, cause the radio access network element to: compute a communication delay between the radio access network element and a source of passive intermodulation, based on receiver group delay information for the radio access network element in the bandwidth of the passive intermodulation; and determine a distance between the source of passive intermodulation and the radio access network element based on the communication delay.

A radio access network element comprising:
- at least one processor;
- and
- at least one memory storing instructions that, when executed by the at least one processor, cause the radio access network element to
- compute a communication delay between the radio access network element and a source of passive intermodulation, based on receiver group delay information for the radio access network element in the bandwidth of the passive intermodulation, and
- determine a distance between the source of passive intermodulation and the radio access network element based on the communication delay.
A method for locating a source of passive intermodulation at a radio access network element, the method comprising:
- computing a communication delay between the radio access network element and the source of passive intermodulation, based on receiver group delay information for the radio access network element in the bandwidth of the passive intermodulation;
- and
- determining a distance between the source of passive intermodulation and the radio access network element based on the communication delay.
A non-transitory computer-readable storage medium storing instructions that, when executed by at least one processor at a radio access network element, cause the radio access network element to perform a method for locating a source of passive intermodulation at the radio access network element, the method comprising:
- computing a communication delay between the radio access network element and the source of passive intermodulation, based on receiver group delay information for the radio access network element in the bandwidth of the passive intermodulation;
- and
- determining a distance between the source of passive intermodulation and the radio access network element based on the communication delay.
