Section: 4.4.1.2 Average UL cell PDCP SDU bit-rate
Content: a) This measurement provides the average cell bit-rate of PDCP SDUs on the uplink. This represents successful transmissions of user plane traffic; control signalling and retransmissions are excluded from this measure. The measurement is split into subcounters per E-RAB QoS level (QCI). b) CC c) This measurement is obtained by accumulating the number of bits leaving the eNodeB/RN on the X2 or S1 interface, and then dividing the sum by the measurement period. The measurement is performed at the PDCP SDU level. PDCP SDUs that were not received over the air interface in the cell (but were forwarded from another eNodeB during handover) are excluded from the count. Separate counters are maintained for each QCI. The sum of all supported per QCI measurements shall equal the total UL cell PDCP SDU bit-rate. In case only a subset of per QCI measurements is supported, a sum subcounter will be provided first. d) Each measurement is an integer value representing the bit-rate measured in kbit/s. The number of measurements is equal to the number of QCIs plus a possible sum value identified by the .sum suffix. e) The measurement name has the form DRB. PdcpSduBitrateUl.QCI where QCI identifies the E-RAB level quality of service class. f) EUtranCellFDD EUtranCellTDD g) Valid for packet switched traffic h) EPS i) One usage of this measurement is to support the KPI "E-UTRAN data Energy Efficiency" defined in [13].
