Description

This measurement provides the retransmission rates of downlink EGPRS RLC data blocks in MCS1-MCS9 coding schemes in a cell in a granularity period. If the retransmission rate is high, you can infer that the signal quality is poor, thus the network needs to be optimized.

Unit

%.

Measurement Point

None.

Formula

Retransmission Rate of Downlink EGPRS MCSx RLC Data Blocks (%) = ((Total Number of Downlink EGPRS MCSx RLC Data Blocks – Total Number of Valid Downlink EGPRS MCSx RLC Data Blocks)/Total Number of Downlink EGPRS MCSx RLC Data Blocks) x 100

Note: MCSx indicates MCS1-MCS9.
