Abstract: Embodiments herein provide various apparatuses and techniques to for enhanced handling of receiver desensitization, “desense,” in electronic devices that is caused by an operation of the device. In an embodiment, sensitivity of a receiver affected by desense may be determined based on receiver sensitivity without desense and a desense offset value. Desense mitigation measures may be applied based on the strength of the signal received by the receiver being less than the receiver sensitivity affected by desense. The desense mitigation measures may include deactivating the device operation that causes desense, enabling the device operation that causes desense only during certain times, and enabling antenna diversity. In some embodiments, various power and signal-to-noise ratio thresholds may be used for conditional application of different desense mitigation measures. For example, to enable receiver diversity on the device, strength of the signal needs to be below one power threshold and above another power threshold.
