Figure 9.1.54.1: Measurement Information message content

Table 9.1.54.1: Measurement Information information element details.

BA_IND (1 bit), BCCH allocation sequence number indication.
The BA_IND is needed to allow the network to discriminate measurements results related to different GSM Neighbour Cell lists sent to the MS, as described in sub-clause 3.4.1.2.1. The value of this parameter is reflected in the ENHANCED MEASUREMENT REPORT message and in the MEASUREMENT REPORT message.

3G_BA_IND (1 bit), 3G Sequence Number.
The 3G_BA_IND is needed to indicate new sets of 3G Neighbour Cell information or E-UTRAN Neighbour Cell information, as described in sub-clause 3.4.1.2.1. The value received is reflected in the MEASUREMENT REPORT and ENHANCED MEASUREMENT REPORT message.

MP_CHANGE_MARK (1 bit), measurement parameters change mark.
This parameter is used to indicate the MS a change of information concerning REPORT PRIORITY, MEASUREMENT INFORMATION, 3G MEASUREMENT INFORMATION and 3G Measurement Control Parameters, as described in sub-clause 3.4.1.2.1,.

MI_INDEX (4 bits) and MI_COUNT (4 bits)
The purpose of the MI_INDEX and MI_COUNT fields is to indicate the number of individual messages within the sequence of MEASUREMENT INFORMATION messages and to assign an index to identify each of them. The MI_INDEX field is binary coded, range 0 to 15, and provides an index to identify the individual MEASUREMENT INFORMATION message. The MI_COUNT field is binary coded, range 0 to 15, and provides the MI_INDEX value for the last (highest indexed) message in the sequence of MEASUREMENT INFORMATION messages.

PWRC, Power control indicator (1 bit field)
The use of this parameter is defined in 3GPP TS 45.008.

Bit
0 PWRC is not set
1 PWRC is set.

REPORT_TYPE (1bit)
This parameter is used to indicate to the mobile to use the Enhanced Measurement report or Measurement report messages for reporting:

Bit

0 The MS shall use the Enhanced Measurement Report message for reporting if at least one BSIC is allocated to each BA (list) frequency. Otherwise, the Measurement Report message shall be used.

1 The MS shall use the Measurement Report message for reporting.

REPORTING_RATE (1 bit)
This parameter is used for measurements, see 3GPP TS 45.008.

bit
0 SACCH rate reporting
1 Reduced reporting rate allowed.

INVALID_BSIC_REPORTING (1 bit)
This field specifies if cells with invalid BSIC and allowed NCC part of BSIC are allowed to be reported or not, see 3GPP TS 45.008.

bit
0 Report on cells with invalid BSIC and allowed NCC part of BSIC is not allowed.
1 Report on cells with invalid BSIC and allowed NCC part of BSIC is allowed.

3G Neighbour Cell Description:

The building of the 3G Neighbour Cell list and the ordering of indices within each Radio Access Technology is described in sub-clause 3.4.1.2.1.1, ‘Deriving the 3G Neighbour Cell list from the 3G Neighbour Cell Description’.

3G WAIT (3 bits)
When 3G_BA_IND is received in a changed state, this parameter indicates the number of instances of MEASUREMENT INFORMATION messages that contain 3G Neighbour Cell Description which shall be received before the MS reports on the new 3G Neighbour Cell list. Two different instances of MEASUREMENT INFORMATION messages are two MEASUREMENT INFORMATION messages with different MI_INDEX. See sub-clause 3.4.1.2.1.

bit
3 2 1
0 0 0 1 instance that contain 3G Neighbour Cell Description shall be received
0 0 1 2 instances that contain Neighbour Cell Description shall be received
:
:
1 1 1 8 instances that contain Neighbour Cell description shall be received

Index_Start_3G (7 bit)
This optional information element indicates the binary value of the first index to use to build this instance of the 3G Neighbour Cell list. When missing, the value 0 is assumed. See sub-clause 3.4.1.2.1.1.

Absolute_Index_Start_EMR (7 bit)
This parameter indicates in binary the value to be added to the indexes of the 3G Neighbour Cell list for reporting 3G Cells with the ENHANCED MEASUREMENT REPORT message (see sub-clause 3.4.1.2.1.1). If different values are received for this parameter in different instances of this message, the instance with the highest index shall be used. If this parameter is absent in all instances of the message, the value "0" shall be used.

NOTE: This parameter is not used for reporting 3G Cells with the MEASUREMENT REPORT message, see sub-clause 10.5.2.20, ‘Measurement Results’.

UTRAN FDD Description:

Bandwidth_FDD (3bit field)
This optional information element will be used for future releases of the protocol. When missing, this indicates the present FDD bandwidth. When present, this shall not be considered as an error; indices of the 3G Neighbour Cell list shall be incremented accordingly.

FDD_ARFCN (14 bit field)
This optional information element is defined as the UARFCN in 3GPP TS 25.101. Any non-supported frequency shall not be considered as an error; indices of the 3G Neighbour Cell list shall be incremented accordingly.

1 parameter value ‘0000000000’ is a member of the set

NOTE: This bit FDD_Indic0 is equivalent to the bit F0 bit in the frequency list information element (see sub-clause 10.5.2.13.3).

NR_OF_FDD_CELLS (5 bit field)
This field defines the number of FDD_CELL_INFORMATION parameters.

FDD_CELL_INFORMATION Field (p bit field)
This field allows to compute a set of 10-bit-long FDD_CELL_INFORMATION parameters, re-using the Range 1024 format compression algorithm, see Annex J: ‘Algorithm to encode frequency list information’. The formulas for decoding are given in the ‘Range 1024 format’ sub-clause, 10.5.2.13.3. The consecutive parameters of this field are concatenated, starting with w1, and then w2, w3…

The total number of bits p of this field depends on the value of the parameter NR_OF_FDD_CELLS = n, as follows:

If n is equal or greater than 17, this shall not be considered as an error; the corresponding index in the 3G Neighbour Cell list shall be incremented by one. The entry created in the 3G Neighbour Cell list does not contain valid information.

For each (10-bit-long) decoded Parameter, bits 1-9 are the Scrambling Code and bit 10 is the corresponding Diversity Parameter.

Scrambling Code (9 bit field)
This parameter indicates the Primary Scrambling Code as defined in 3GPP TS 25.213.

TDD_ARFCN (14 bit field)
This optional information element is defined as the UARFCN in 3GPP TS 25.102. Any non-supported frequency shall not be considered as an error; indices of the 3G Neighbour Cell list shall be incremented accordingly.

TDD_Indic0, information 0 indicator (1 bit):
This field indicates if the TDD_CELL_INFORMATION parameter value ‘0000000000’ is a member of the set.

TDD_CELL_INFORMATION Field (q bit field)
This field allows to compute a set of 9-bit-long TDD_CELL_INFORMATION parameters, re-using the Range 512 format compression algorithm, see Annex J: ‘Algorithm to encode frequency list information’. The formulas for decoding are given in the ‘Range 512 format’ sub-clause, 10.5.2.13.4, with w0=0. The consecutive parameters of this field are concatenated, starting withw1, and then w2, w3…
