1. A method comprising:
- determining whether a communication channel of a first wireless interface of a device is adjacent to a frequency band in which a second wireless interface of the device is configured to communicate, wherein the communication channel is one of a plurality of communication channels available to the first wireless interface, and wherein the first wireless interface is configured to communicate using one of the plurality of communication channels as selected by a base station with which the first wireless interface is associated;
altering, responsive to the act of determining, a channel measurement report generated by the first wireless interface by degrading channel measurement results of the channel measurement report by a predetermined factor; and
transmitting, via the first wireless interface, the altered channel measurement report to the base station associated with the first wireless interface effective to prevent the base station from selecting, for subsequent use by the first wireless interface, the communication channel adjacent to the frequency band in which the second wireless interface is configured to communicate.

Abstract
The present disclosure describes techniques for avoiding interference among multiple radios. In some aspects a communication channel of a first wireless interface of a device is determined to be adjacent to a frequency band in which a second wireless interface of the device is configured to communicate and channel measurement results are altered prior to transmission by the first wireless interface to a base station, effective to prevent the base station from selecting, for use by the first wireless interface, the channel adjacent to the frequency band of the second wireless interface.

10. A system comprising:
-
a first wireless interface configured to communicate using a communication channel selected from a plurality of communication channels, the communication channel selected by a base station with which the first wireless interface is associated; a second wireless interface configured to communicate in a frequency band; and an interference manager configured to; determine whether the channel selected for communications of the first wireless interface is adjacent to the frequency band in which the second wireless interface of the system is configured to communicate; alter, responsive to the act of determining, a channel measurement report generated by the first wireless interface by degrading channel measurement results of the channel measurement report by a predetermined factor; and transmit, via the first wireless interface, the altered channel measurement report to the base station associated with the first wireless interface effective to prevent the base station from selecting, for subsequent use by the first wireless interface, the communication channel adjacent to the frequency band in which the second wireless interface is configured to communicate. - View Dependent Claims (11, 12, 13, 14)

15. A non-transitory computer-readable memory device comprising computer-executable instructions that, responsive to execution by one or more processors, implement an interference manager to:
-
determine whether a communication channel of a first wireless interface of a device is adjacent to a frequency band in which a second wireless interface of the device is configured to communicate, wherein the communication channel is one of a plurality of communication channels available to the first wireless interface, and wherein the first wireless interface is configured to communicate using one of the plurality of communication channels as selected by a base station with which the first wireless interface is associated; alter, responsive to the act of determining, a channel measurement report generated by the first wireless interface by degrading channel measurement results of the channel measurement report by a predetermined factor; and transmit, via the first wireless interface, the altered channel measurement report to the base station associated with the first wireless interface effective to prevent the base station from selecting, for subsequent use by the first wireless interface, the communication channel adjacent to the frequency band in which the second wireless interface is configured to communicate. - View Dependent Claims (16, 17, 18, 19, 20)
