Systems, apparatus, and methods for mitigating transmitter induced desense

摘要

This disclosure provides systems, methods, and apparatus for mobile transmit diversity. In one aspect a method of controlling a transmit power level of a wireless communications apparatus is provided. The method includes adjusting the transmit power level of a transmitter of the wireless communications apparatus to a first transmit power level in response to detecting a de-sense event indicative of interference with a signal received by a receiver of the wireless communications apparatus due to emissions from the transmitter. The method further includes maintaining the transmit power level substantially at the first transmit power level for a first time interval in response to adjusting the transmit power level to the first transmit power level. The method further includes adjusting a transmit power level limit of the transmitter after the time interval at a rate for a second time interval.

1. A method of controlling a transmit power level of a wireless communications apparatus, the method comprising:
detecting a de-sense event, wherein detecting the de-sense event comprises:
detecting a number of consecutive incorrectly received frames being equal to or greater than a first threshold, wherein a transmitter of the wireless communications apparatus is de-activated in response to detecting that the number of consecutive incorrectly received frames is equal to or greater than the first threshold; anddetecting that a change in a receive power level of a receiver of the wireless communications apparatus before and after the transmitter of the wireless communications apparatus is de-activated is greater than a second threshold; adjusting the transmit power level of the transmitter of the wireless communications apparatus to a first transmit power level in response to detecting the de-sense event; maintaining the transmit power level substantially at the first transmit power level for a first time interval in response to adjusting the transmit power level to the first transmit power level; and gradually adjusting a transmit power level limit of the transmitter after the first time interval, at a rate, for a second time interval.
