Method and apparatus for reliable transmit power and timing control in wireless communication

A method comprising:

• receiving a control symbol in a burst sent with variable transmit power;
• determining reliability of the control symbol based on received signal quality of the control symbol and a dynamic signal-to-interference-plus-noise ratio (SINR) threshold based on a target SINR threshold and a difference between a first SINR required to obtain a target frame error rate (FER) and a second SINR required to achieve a target symbol error rate (SER);
• adjusting a control loop if the control symbol is deemed reliable;
• and
• maintaining the control loop if the control symbol is deemed unreliable.
