Section: 6.2.3.2 Virtual resource blocks of distributed type
Content: Virtual resource blocks of distributed type are mapped to physical resource blocks as described below. Table 6.2.3.2-1: RB gap values The parameter is given by Table 6.2.3.2-1. For , only one gap value is defined and . For , two gap values and are defined. Whether or is signaled as part of the downlink scheduling assignment as described in TS 36.212[ Evolved Universal Terrestrial Radio Access (E-UTRA); Multiplexing and channel coding ]  [3]. Virtual resource blocks of distributed type are numbered from 0 to, where for and for . Consecutive VRB numbers compose a unit of VRB number interleaving, where for and for . Interleaving of VRB numbers of each interleaving unit is performed with 4 columns and rows, where , and is RBG size as described in TS 36.213[ Evolved Universal Terrestrial Radio Access (E-UTRA); Physical layer procedures ]  [4]. VRB numbers are written row by row in the rectangular matrix, and read out column by column. nulls are inserted in the last rows of the 2nd and 4th column, where . Nulls are ignored when reading out. The VRB numbers mapping to PRB numbers including interleaving is derived as follows: For even slot number ; , where , and , where and is obtained from the downlink scheduling assignment as described in TS 36.213[ Evolved Universal Terrestrial Radio Access (E-UTRA); Physical layer procedures ]  [4]. For odd slot number ; Then, for all ; . Virtual resource blocks of distributed type are not applicable to BL/CE UEs.
