name: QCI
full_form: QoS Class Identifier
context: This measurement provides the usage (in percentage) of physical resource blocks (PRBs) on the uplink for DTCH traffic. The measurement is split into subcounters per E-RAB QoS level (QCI). If there is one or more RNs served in a cell, for that cell the eNodeB performs PRB usage measurements separately for all traffic (including transmissions to/from RNs and UEs directly connected to the eNodeB) and for RN traffic. The measurement is also applicable to RNs. SI This measurement is obtained according to the definition in 3GPP TS 36.314[ Evolved Universal Terrestrial Radio Access  (E-UTRA); Layer 2 - Measurements ]  [11]. Separate counters are maintained for each QCI. The sum of all supported per QCI measurements shall equal the total PRB usage for DTCH. In case only a subset of per QCI measurements is supported, a sum subcounter will be provided first. Each measurement is an integer value from 0 to 100. The number of measurements is equal to the number of QCIs plus a possible sum value identified by the .sum suffix. The measurement name has the form RRU.PrbUl.QCI, which indicats the UL PRB Usage for all traffic RRU.PrbUlRN.QCI, which indicates the UL PRB Usage for the RN traffic where QCI identifies the E-RAB level quality of service class.

description: The QoS Class Identifier (QCI) is a key parameter in the Evolved Universal Terrestrial Radio Access Network (E-UTRAN) that identifies the quality of service class for E-RAB (Evolved Radio Access Bearer) levels. It is used to differentiate and prioritize traffic based on its specific requirements, such as latency, throughput, and packet loss rate. The QCI value is associated with a set of performance characteristics that define the treatment of packets belonging to a particular bearer or service.
explanation: QCI is classified as an Identifier because it serves as a unique label for identifying and distinguishing between different quality of service classes in E-UTRAN, enabling network elements to apply appropriate traffic handling policies based on the specific QoS requirements of each service or application.
