Table 7-11 Description of the HSDPA indicators

Indicator Description

Serving Cell SC Provides the scrambling code of the serving cell of the HADPA.

Serving Cell Ec/Io Provides the Ec/Io value of the serving cell of the HSDPA.

Serving Cell RSCP Provides the receive signal code power of the serving cell of the HSDPA

Scheduled Rate (Delta)

Provides the transient rate of scheduling at the MAC layer in the unit of kbit/s.

Served Rate (Delta) Provides the transient rate of transmission (including failed transmission and retransmission) at the MAC layer in the unit of kbit/s.

MAC Layer Rate (Delta)

Provides the transient rate of transmission (excluding failed transmission and retransmission) at the MAC layer in the unit of kbit/s.

SCCH Success Rate (Delta)

Provides the transient usage of the HS-SCCH channel in the unit of percent.

DSCH SBLER (Delta)

Provides the transient BLER at the MAC layer in the unit of percent.

Provides the average value of all the channel quality indicators (CQIs) of HS-DSCH in 200 ms. The value range is 0 to 30.

HS-DSCH Retrans Rate (Delta)

Provides the HS-DSCH retransmission rate.

HS-PDSCH Codes Provides the average value of all the UE-used codes in 200 ms.

The value range is 1 to 15.

HS-DSCH Decoding Statistics

Provides the statistics on HS-DSCH decoding, as described in Table 7-12.

Table 7-12 Description of the HS-DSCH Decoding Statistics indicators

Indicator Description

Copyright © Huawei Technologies Co., Ltd. Issue 06 (2009-06-20)

Indicator Description

SB Suc Number of TB transmission successes at the MAC layer

Dup. SB Suc Number of retransmissions of the same TB, that is, the number of negative acknowledgement (NACK) messages to which the NodeB translates from the ACK messages provided by the UE upon successful decoding

ACK>NACK/DTX (Discontinuous Transmission)

Retransmission ratio of correct frames in the unit of percent

SBLER BLER at the MAC layer in the unit of percent 1st SBLER BLER ratio of the first frame in the unit of percent

Block Fail Number of failed TB transmissions after retransmissions, that is, the number of frames transmitted at the RLC layer after failed retransmissions at the MAC layer

Block Suc Number of TB transmission successes, which equals the value of SB success

Res. BLER BLER ratio at the RLC layer in the unit of percent All TBS Statistics Sum of statistics on channel decoding of each TBS 1 Times Number of frames successfully transmitted during the first

transmission

2 Times Number of frames successfully transmitted at the second attempt after the first attempt failed

3 Times Number of frames successfully transmitted at the third attempt after the first two attempts failed

4 Times Number of frames successfully transmitted at the fourth attempt after the first three attempts failed

5 Times Number of frames successfully transmitted at the fifth attempt after the first four attempts failed

The fifth retransmission is initiated by the RLC layer after the Hybrid Automatic Repeat Request (HARQ) is set in the device.

≥ 6 Times Number of frames successfully transmitted at the sixth or later attempt after all the previous attempts failed

In addition, the Assistant provides the statistics on channel decoding according to each TBS.
