Section: 4.5.10 Distribution of DL total PRB ssage
Content: a) This measurement provides the distribution of samples with total usage (in percentage) of physical resource blocks (PRBs) on the downlink in different ranges. This measurement is a useful measure of whether a cell is under high loads or not in the scenario which a cell in the downlink may experience high load in certain short times (e.g. in a second) and recover to normal very quickly. b) CC c) Each measurement sample is obtained according to the definition in TS 36.314[ Evolved Universal Terrestrial Radio Access  (E-UTRA); Layer 2 - Measurements ] [11] clause 4.1.10.1. Depending on the value of the sample, the proper bin of the counter is increased. The number of samples during one measurement period is provided by the operator. d) A set of integers. Each representing the (integer) number of samples with a DL total PRB percentage usage in the range represented by that bin. e) RRU.PrbTotDlDist.BinX, which indicates the distribution of DL PRB Usage for all traffic. f) EUtranCellFDD EUtranCellTDD g) Valid for packet switched traffic h) EPS i) The distribution information is a key input to network capacity planning and load balancing.
