Section: 4.5.4 UL Total PRB Usage
Content: This measurement provides the total usage (in percentage) of physical resource blocks (PRBs) on the uplink for any purpose. 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]. A single integer value from 0 to 100.
