1. A multi-radio device, comprising:
- a first radio comprising a transmitter; and
a second radio comprising a receiver and a counter, the second radio configured to;
selectively monitor, using the receiver, a channel to obtain data representative of a measurement of a predefined channel parameter;
receive, using a communication path distinct from a wireless communication path between the first and second radios, a signal from the first radio providing data indicating whether the transmitter of the first radio is transmitting;
determine, based on the received signal, a length of time that the transmitter was transmitting during a sampling period for the measurement, wherein the counter stores a counter value indicating the length of time the transmitter was transmitting during the sampling period; and
based on the determined length of time, selectively exclude measurements of the predefined channel parameter obtained while the transmitter of the first radio is transmitting,wherein the second radio ignores data representative of a measurement of the predefined channel parameter obtained during the sampling period responsive to determining the counter value is above a predetermined threshold value.

Abstract
In an example embodiment disclosed herein there is described a multi-radio device which comprises a first radio that first radio comprises a transmitter, and a second radio that second radio comprises a receiver that monitors a channel to obtain data representative of a predefined channel parameter. The second radio is operable to receive a signal from the first radio that indicates when the transmitter of the first radio is transmitting. The receiver of the second radio selectively excludes data representative of a predefined channel parameter based on whether the transmitter of the first radio is transmitting.

15. Logic encoded in a non-transitory, tangible computer readable medium for execution by a processor, and when executed by the processor the logic being operable to:
-
obtain, from a receiver of an associated multi-radio device having one or more wireless receivers, first data representative of a measured channel parameter, wherein the first data is obtained during a predetermined sampling period; obtain, using a communication path distinct from the one or more wireless receivers, second data indicating whether a co-located transmitter is transmitting; determine, based on the second data, a length of time that the co-located transmitter was transmitting during the sampling period; store a counter value indicating the length of time; based on the determined length of time, selectively discard the first data representative of the measured channel parameter while the co-located transmitter is transmitting, wherein selectively discarding the first data comprises discarding the first data responsive to determining the counter value is above a predetermined threshold value; and aggregate the first data representative of the measured channel parameter. - View Dependent Claims (16, 17)

18. A method, comprising:
-
obtaining a measurement of a channel parameter by a receiver, the receiver associated with a multi-radio device having one or more wireless receivers; receiving, using a communication path distinct from the one or more wireless receivers, a signal indicating whether a transmitter that is co-located with the receiver is transmitting; determining, based on the received signal, a length of time that the transmitter was transmitting during a sampling period for the measurement; based on the determined length of time, ignoring measurements for the channel parameter while the received signal indicates the transmitter is transmitting, wherein ignoring measurements for the channel parameter while the received signal indicates the transmitter is transmitting comprises; raising a threshold for the measurement of the channel parameter while the transmitter is transmitting; and ignoring measurements of the channel parameter that are below the raised threshold; and aggregating measurements of the channel parameter.
