Detection of radio frequency interference in wireless communication systems
First Claim
1. A method comprising causing at least one access terminal that is configured to transmit data to a radio node in a sector of a radio access network to alter transmission, while transmission is altered, determining a power of a signal received at the radio node, and updating an average value of signal power using the power measured.

Abstract
A device causes at least one access terminal that is configured to transmit datal to a radio node in a sector of a radio access network to alter transmission. While transmission is altered, the device determines a power of a signal received at the radio node, and updates an average value of signal power using the power measured. A device receives, from one or more access terminals that are configured to receive data from a radio node in a sector of a radio access network, a requested rate at which information should be transmitted to each access terminal, receives from the access terminals information about quality of signals received from the radio node, and generates an event if the requested rate and the information about quality of signals fail to satisfy a condition. An access terminal, located in the vicinity of a first radio node configured to transmit data in a sector of a radio access network, measures signal power of pilot signals received by the access terminal.

43. A method comprising
causing any access terminals configured to transmit data to a radio node in a sector of a radio access network to alter transmission, while transmission is altered, measuring a power of a signal received at the radio node, updating an average value of signal power using the power measured, receiving from the access terminals a requested rate at which information should be transmitted to each access terminal, receiving from the access terminals information about quality of signals received from the radio node, and generating an event if either the rate and the information about quality of signals fail to satisfy a condition, or the average value of signal power is greater than a threshold.

45. A medium bearing instructions to cause a radio network controller to
receive from access terminals, configured to receive data from a radio node in a sector of a radio access network, a requested rate at which information should be transmitted to each access terminal, receive from the access terminals information about quality of signals received from the radio node, and generate an event if the rate and the information about quality of signals fail to satisfy a condition.
-
46. A medium bearing instructions to cause an access terminal, configured to receive data and located at a radio node configured to transmit data traffic in a sector of a radio access network, to
measure signal power of a pilot signal transmitted by the radio node to the access terminal, and communicate information about the measured power to a radio network controller.

47. A medium bearing instructions to cause a radio network controller to
receive, from an access terminal, information about measured signal power of a pilot signal transmitted by a radio node configured to transmit data traffic in a sector of a radio access network, compute a current signal-to-noise ratio of the signal power of the pilot signal transmitted by the radio node, update an average value of the signal-to-noise ratio with the current signal-to-noise ratio, and generate an event based on the updated average value.
