8.6.7 Measurement information elements
On reception of measurement information elements the UE shall:
1> store the received information in the variable MEASUREMENT_IDENTITY and CELL_INFO_LIST as
specified;
1> perform further actions as specified in subclause 8.6.7 and subclause 8.4, based on the content of the variable
MEASUREMENT_IDENTITY.
If a configuration is considered to be invalid the UE may:
1> set the variable CONFIGURATION_INCOMPLETE to TRUE.
8.6.7.1 Measurement validity
If the IE "measurement validity" for a given measurement has not been included in measurement control information,
the UE shall delete the measurement associated with the variable MEASUREMENT_IDENTITY after the UE makes a
transition to a new state.
If the IE "measurement validity" for this measurement has been included in measurement control information, the UE
shall save the measurement associated with the variable MEASUREMENT_IDENTITY. The IE "UE state" defines the
scope of resuming the measurement.
If the "UE state" is defined as "all states", the UE shall continue the measurement after making a transition to a new
state. This scope is assigned for traffic volume measurement type and UE positioning measurement type. For traffic
volume measurement type this scope can only be applied by the UE if the IE " traffic volume measurement object" has
been included in measurement control information. If the IE " traffic volume measurement object" has not been
included in measurement control information, the UE shall not save the measurement control information in variable
MEASUREMENT_IDENTITY, but shall send a MEASUREMENT CONTROL FAILURE message to the UTRAN
with failure cause "Configuration incomplete". For 1.28 Mcps TDD, this scope is also assigned for intra-frequency
measurement type and inter-frequency measurement type.
If the "UE state" is defined as "all states except CELL_DCH", the UE shall store the measurement to be resumed after a
subsequent transition from CELL_DCH state to any of the other states in connected mode. This scope is assigned for
traffic volume measurement type or UE positioning measurement type. For 1.28 Mcps TDD, this scope is also assigned
for intra-frequency measurement type and inter-frequency measurement type.
If the "UE state" is defined as "CELL_DCH", the UE shall store the measurement to be resumed after a subsequent
transition to CELL_DCH state.
For FDD, 3.84/7.68 Mcps TDD, if the IE "measurement type" received in a MEASUREMENT CONTROL message is
set to "inter-frequency measurement" or "intra-frequency measurement" and the IE "measurement validity" is present
and is set to a value other than "CELL_DCH", the UE behaviour is unspecified.
8.6.7.2 Filter coefficient
If the IE "Filter coefficient" is received the UE shall, depending on the measurement quantity (see Table 8.6.7.2), apply
filtering of the measurements for that measurement quantity according to the formula below. This filtering shall be
performed by the UE before UE event evaluation. The UE shall depending on the reporting quantity (see Table 8.6.7.2),
also filter the measurements reported in the IE "Measured results" and "Measured results on secondary UL frequency",
or "E-UTRA measured results". The filtering shall not be performed for the measurements reported in the IE "Measured
results on RACH" and for cell-reselection in connected or idle mode.
The filtering shall be performed according to the following formula.
F
n
= ( 1−
a)
⋅ Fn−1
+ a ⋅ M
n
The variables in the formula are defined as follows:
F n is the updated filtered measurement result
F n-1 is the old filtered measurement result
