By-x the moment as switching on the time, i.e., switch is advanced by the x time compared with 0 moment and opens.Baseband chip can make the y moment
For the shut-in time of switch, i.e. switch is delayed the y time compared with 0 moment and is closed.
It should be noted that the shut-in time of switch can also be with power coupler from there is transmission power to no transmitting function
The time point m of rate is benchmark time point, and baseband chip can be using the m+y moment as the shut-in time of switch, i.e., switch is compared with the m moment
The y time is delayed to close.
So far, the first time sequence parameter of the first time sequence parameter of switch and antenna tuner is adjusted by baseband chip dynamic
