10.5.2.20	Measurement Results
The purpose of the Measurement Results information element is to provide the results of the measurements made by the mobile station on the serving cell and the neighbour cells.
The Measurement Results information element is coded as shown in figure 10.5.47/GSM 04.18 and table 10.5.47/GSM 04.18.
The Measurement Results is a type 3 information element with 17 octets length.

RXLEV-NCELL  i, Result of measurement on the i'th neighbouring  cell (octet 5, 7, 8, 9, 10, 11, 12, 13, 14, 15 and 16)
If the i’th neighbouring cell is a GSM cell, the RXLEV-NCELL field is coded as the binary representation of a value N. N corresponds according to the mapping defined in TS. GSM 05.08 to the received signal strength on the i'th neighbouring cell. See note 1 & 2.
If the i’th neighbouring cell is an UMTS cell, the RXLEV-NCELL field is coded as the binary representation of a value N. N corresponds to the mapping defined in TS. GSM 05.08 to the received measurement quantity on the i’th neighbouring cell. The UMTS measurement quantity is defined in UMTS Neighbour Cells Description information element in System Info message 5gamma. See note 1 & 2.
Range: 0 to 63.

Table 10.5.47/GSM 04.18: Measurement Results information element (concluded)
BCCH-FREQ-NCELL   i,   Position of the i'th neighbouring cell in the BCCH channel list (octet 6, 8,10, 12, 14, 15, 16 and 17)

The  BCCH-FREQ-NCELL  i field is coded as the binary representation of the position, starting with 0, of the i'th neighbouring cell in the BCCH channel list. The BCCH channel list is composed of one, two or three BCCH channel sub lists, each sub list is  defined by reference neighbour cells description information element or elements. In the latter cases the set is the union of the sets  defined by the  neighbour cells description information elements.

In each BCCH channel sub list derived from the neighbour cells description information element in System Information 2/2bis/2ter/ or 5/5bis/5ter the absolute RF channel numbers are placed in increasing order of ARFCN, except that ARFCN 0, if included in the set, is put in the last position in the sub list. The BCCH channel sub list derived from System Information 5gammais placed after the ARFCN list in the order they occur in the SI5gamma message.  The BCCH channel list consists either of only the sub list derived from the neighbour cells description information element(s) in System Information 2/5 (and possible 2bis/5bis) or of that sub list immediately followed by the sub list derived from the neighbour cells description information element in System Information 2ter/5ter/5gammafor the case System Information 2ter/5ter/5gamma is also received. If the set of ARFCNs/ UMTS scrambling code frequency combinations defined by the reference neighbour cells description information element or elements includes frequencies (it is assumed that the mobile supports all scrambling codes) that the mobile station does not support then these ARFCNs/ UMTS scrambling code frequency combinations shall be included in the list.
The notation 2/5 etc. means that the rules above apply to the neighbour cells description information elements received in System Information 2, 2bis and 2ter and to those received in System Information 5, 5bis, 5ter and 5gamma separately.

See note 1 & 2.

Range: 0 to 31.

BSIC-NCELL i, Base station identity code of the i'th neighbouring cell (octet 6, 7, 8, 9, 10, 11, 13, 15  and 17)

The  BSIC-NCELL i  field is coded as the binary representation of the base station identity code of the i'th neighbouring cell. See note 1 & 2.

Range: 0 to 63.

NOTE 1: If the field extends over two octets the highest numbered bit of the lowest numbered octet is the most significant and the lowest numbered bit of the highest numbered octet is the least significant.

NOTE 2: If  NO-NCELL-M < 6 the remaining RXLEV-NCELL i,  BS-FREQ-NCELL i and BSIC-NCELL i fields (NO-NCELL-M < i <= 6) shall be coded with a "0" in each bit.
