BLER and SIR

Block Error Rate (BLER) is an analysis of transmission errors on the radio interface.
It is based on analysis of cyclic redundancy check (CRC) results for radio link control (RLC) transport blocks and computed as below:
Signal-to-Interference Ratio (SIR), also known as the carrier-to-interference ratio (C/I, CIR), is the quotient between the average received modulated carrier power and the average received co-channel interference power.

For UL Power Control:

Example: Mobility movement > Handover trigger > SIR Error > UL BLER
