PWR_REP_THRESH, PWR_REP_FRAMES, and PWR_REP_DELAY
Definition: These three parameters relate to the reporting on the reverse link of bad frames received by the mobile. They, therefore, are critical to the forward-link power control. PWR_REP_THRESH is the power control reporting threshold. This is the number of bad frames allowed at the mobile receiver during a measurement period before it is to generate a Power Measurement Report Message. PWR_REP_FRAMES is the power control reporting frame count. This number is used to derive the number of frames over which the mobiles are to count frame errors. PWR_REP_DELAY is the power report delay. This is the period of time, expressed as a multiple of 4 frames, that the mobile station will wait following a Power Measurement Report Message before it restarts frame counting for power control purposes.

PWR_REP_THRESH, PWR_REP_FRAMES, and PWR_REP_DELAY
Example: PWR_REP_THRESH is a 5-bit data word. PWR_REP_FRAMES is a 4-bit word used to calculate an exponent of 2 equal to PWR_REP_FRAMES/2. Suppose PWR_REP_FRAMES equals decimal 12. The exponent PWR_REP_FRAMES/2 equals 6 and 26 equals 64. This number is then multiplied by 5 to yield the actual frame count of 320 over which the mobile is to count frame errors. If a Frame Error Rate (FER) of about 1% is desired, the PWR_REP_THRESH would likely be about decimal 3. If there are more than 3 bad frames out of 320 frames, then the FER is probably greater than 1%. The PWR_REP_DELAY is a 5-bit word suggesting delays of several multiples of the 4-frame time (80 msec) before statistics are restarted following a Power Measurement Report Message.
