- *     Function: calculatePRB
+ *     Function: schAllocFreqDomRscType0

+ *     This function does allocation in frequency domain resource.
+ *     This is a bitmap defining  non-overlapping groups of 6 PRBs in ascending order.

  *  @param[in]  startPrb - start PRB from where the freq alloc starts.  
  *  @param[in]  prbSize - number of PRBs to be allocted.
  *  @param[in]  freqDomain - 6 bytes of info, each bit represents a group of 6 PRB.
