•
when the mobile is not in READY mode, RLC/MAC Data Throughputs are reported only if the number
of transmitted bytes has changed over the reporting period
4.2.3 Total RLC blocks transmitted
The Total number of RLC blocks transmitted is defined as follows:
•
only DATA blocks are take into account
•
all received or sent blocks are considered, including those blocks that are retransmitted in NACKED or
PENDING ACK state
It is reported every second, unless it has not changed over the reporting period.
4.3 MEASUREMENT INFO PARAMETER
This screen is defined in 2.5.5.
The Downlink RLC BLER is computed over a period of
1 second
. It is defined as follows :
BLER = N
ERRORED
/ N
TOTAL
where:
•
N
ERRORED
= number of data blocks received with a bad CRC and a TFI corresponding to the current
downlink TFI allocated to the mobile
•
N
TOTAL
= total number of data blocks received with a TFI corresponding to the current downlink TFI
allocated to the mobile
NOTE
: the received RLC/MAC blocks are filtered according to the PAYLOAD TYPE and TFI fields of their
RLC/MAC headers. Those fields can be affected by transmission errors, so the two parameters above
(N
ERRORED
and N
TOTAL
) can only be
estimated
. As a consequence the reported value must be considered
as an
estimation
of the Block Error Rate of the radio link between the network and that particular mobile.
