All data shown in the header pertains to the current serving cell.

EARFCN: E-UTRA ARFCN (Absolute Radio Frequency Channel Number). This attribute gives the downlink E-UTRA Absolute Radio Frequency Channel Number of the cell the UE is camping on. Carrier Aggregation (LTE Advanced): In CA mode, this attribute gives the downlink E-UTRA Absolute Radio Frequency Channel Number of Primary Cell (PCC).

PCI: Physical Cell Identity, this attribute gives the Physical Cell Identity of the cell the UE is camping on. Carrier Aggregation (LTE Advanced): In CA mode, this attribute gives the Physical Cell Identity of Primary Cell (PCC).

RSRP: Reference Signal Received Power. This attribute gives the Received Power of the Reference Signal for the cell the UE is camping on. The unit is dBm. Carrier Aggregation (LTE Advanced): In CA mode, this attribute gives the Received Power of the Reference Signal of the Primary Carrier (PCC).

SINR: This attribute gives the Signal to Interference + Noise ratio measured by the UE. The unit is dB. Carrier Aggregation (LTE Advanced): In CA mode, this attribute gives the Signal to Interference + Noise ratio of the Primary Carrier (PCC).

PLMN: as defined above, see before

TAC: TAC: Serving cell Tracking Area Code

ECellID: ECI, E-UTRAN Cell Identifier. Used to identify a cell uniquely within a PLMN. Length: 28 bits.  3GPP 36.300, section 8.2
