4 Control of UE/E-UTRAN measurements
In this chapter the general measurement control concept of the higher layers is briefly described to provide an
understanding on how L1 measurements are initiated and controlled by higher layers.
With the measurement specifications L1 provides measurement capabilities for the UE and E-UTRAN. These
measurements can be classified in different reported measurement types: intra-frequency, inter-frequency, inter-system,
traffic volume, quality and UE internal measurements (see the RRC Protocol [7]).
ETSI
---------------------- Page: 8 ----------------------
3GPP TS 36.214 version 15.2.0 Release 15 8 ETSI TS 136 214 V15.2.0 (2018-07)
In the L1 measurement definitions, see chapter 5, the measurements are categorised as measurements in the UE (the
messages for these will be described in the MAC Protocol [6] or RRC Protocol [7] or LPP Protocol [11]) or
measurements in the E-UTRAN (the messages for these will be described in the Frame Protocol or LPPa Protocol [12]).
To initiate a specific measurement, the E-UTRAN transmits a 'RRC connection reconfiguration message' to the UE
including a measurement ID and type, a command (setup, modify, release), the measurement objects, the measurement
quantity, the reporting quantities and the reporting criteria (periodical/event-triggered), see [7] or E-SMLC transmits an
'LPP Request Location Information message' to UE, see [11].
When the reporting criteria are fulfilled the UE shall answer with a 'measurement report message' to the E-UTRAN
including the measurement ID and the results or an 'LPP Provide Location Information message' to the E-SMLC, see
[11].
For idle mode, the measurement information elements are broadcast in the System Information.
5 Measurement capabilities for E-UTRA
In this chapter the physical layer measurements reported to higher layers are defined.

5.1.1 Reference Signal Received Power (RSRP)
Definition Reference signal received power (RSRP), is defined as the linear average over the power
contributions (in [W]) of the resource elements that carry cell-specific reference signals within the
considered measurement frequency bandwidth.
For RSRP determination the cell-specific reference signals R0 according to TS 36.211 [3] shall be
used. If the UE can reliably detect that R is available, it may use R in addition to R to
1 1 0
determine RSRP.
If higher layers indicate measurements based on discovery signals, the UE shall measure RSRP
in the subframes in the configured discovery signal occasions. For frame structure 1 and 2, if the
UE can reliably detect that cell-specific reference signals are present in other subframes, the UE
may use those subframes in addition to determine RSRP.
The reference point for the RSRP shall be the antenna connector of the UE.
If receiver diversity is in use by the UE, the reported value shall not be lower than the
corresponding RSRP of any of the individual diversity branches.
Applicable for RRC_IDLE intra-frequency,
RRC_IDLE inter-frequency,
RRC_CONNECTED intra-frequency,
RRC_CONNECTED inter-frequency
NOTE 1: The number of resource elements within the considered measurement frequency bandwidth and within the
measurement period that are used by the UE to determine RSRP is left up to the UE implementation with
the limitation that corresponding measurement accuracy requirements have to be fulfilled.
NOTE 2: The power per resource element is determined from the energy received during the useful part of the
symbol, excluding the CP.

5.1.3 Reference Signal Received Quality (RSRQ)
Definition Reference Signal Received Quality (RSRQ) is defined as the ratio N×RSRP/(E-UTRA carrier
RSSI), where N is the number of RB's of the E-UTRA carrier RSSI measurement bandwidth. The
measurements in the numerator and denominator shall be made over the same set of resource
blocks.
E-UTRA Carrier Received Signal Strength Indicator (RSSI), comprises the linear average of the
total received power (in [W]) observed only in certain OFDM symbols of measurement
subframes, in the measurement bandwidth, over N number of resource blocks by the UE from all
sources, including co-channel serving and non-serving cells, adjacent channel interference,
thermal noise etc.
Unless indicated otherwise by higher layers, RSSI is measured only from OFDM symbols
containing reference symbols for antenna port 0 of measurement subframes. If higher layers
indicate all OFDM symbols for performing RSRQ measurements, then RSSI is measured from
all OFDM symbols of the DL part of measurement subframes. If higher-layers indicate certain
subframes for performing RSRQ measurements, then RSSI is measured from all OFDM symbols
of the DL part of the indicated subframes.
If higher layers indicate measurements based on discovery signals, RSSI is measured from all
OFDM symbols of the DL part of the subframes in the configured discovery signal occasions.
The reference point for the RSRQ shall be the antenna connector of the UE.
If receiver diversity is in use by the UE, the reported value shall not be lower than the
corresponding RSRQ of any of the individual diversity branches.
Applicable for RRC_IDLE intra-frequency,
RRC_IDLE inter-frequency,
RRC_CONNECTED intra-frequency,
RRC_CONNECTED inter-frequency
5.1.4 UTRA FDD CPICH RSCP
Definition Received Signal Code Power, the received power on one code measured on the Primary
CPICH. The reference point for the RSCP shall be the antenna connector of the UE. If Tx
diversity is applied on the Primary CPICH the received code power from each antenna shall be
separately measured and summed together in [W] to a total received code power on the Primary
CPICH. If receiver diversity is in use by the UE, the reported value shall not be lower than the
corresponding CPICH RSCP of any of the individual receive antenna branches.
Applicable for RRC_IDLE inter-RAT,
RRC_CONNECTED inter-RAT
5.1.5 UTRA FDD carrier RSSI
Definition The received wide band power, including thermal noise and noise generated in the receiver,
within the bandwidth defined by the receiver pulse shaping filter. The reference point for the
measurement shall be the antenna connector of the UE. If receiver diversity is in use by the UE,
the reported value shall not be lower than the corresponding UTRA carrier RSSI of any of the
individual receive antenna branches.
Applicable for RRC_IDLE inter-RAT,
RRC_CONNECTED inter-RAT
NOTE: This definition does not correspond to a reported measurement. This definition is just an intermediate
definition used in the definition of UTRA FDD CPICH Ec/No.

5.1.6 UTRA FDD CPICH Ec/No
Definition The received energy per chip divided by the power density in the band. If receiver diversity is not
in use by the UE, the CPICH Ec/No is identical to CPICH RSCP/UTRA Carrier RSSI.
Measurement shall be performed on the Primary CPICH. The reference point for the CPICH
Ec/No shall be the antenna connector of the UE. If Tx diversity is applied on the Primary CPICH
the received energy per chip (Ec) from each antenna shall be separately measured and summed
together in [Ws] to a total received chip energy per chip on the Primary CPICH, before
calculating the Ec/No. If receiver diversity is in use by the UE, the measured CPICH Ec/No value
shall not be lower than the corresponding CPICH RSCP/UTRA Carrier RSSI of receive antenna
i i
branch i .
Applicable for RRC_IDLE inter-RAT,
RRC_CONNECTED inter-RAT

Definition Received Signal Strength Indicator, the wide-band received power within the relevant channel
bandwidth. Measurement shall be performed on a GSM BCCH carrier. The reference point for
the RSSI shall be the antenna connector of the UE.
Applicable for RRC_IDLE inter-RAT,
