This routine first allocates random frequency assignments for SI and RA SDUs using distributed VRB allocations and adds the corresponding DCI SDU to the DCI buffer for PHY. It then loops over the UE specific DCIs previously allocated and fills in the remaining DCI fields related to frequency allocation. It assumes localized allocation of type 0 (DCI.rah=0). The allocation is done for tranmission modes 1,2,4.
