Choice: 0 or 1 separated by commas
Length: 5 or 20 (Depends on Subframe Allocation)
Default: 1,...,1 (All 1's)
Enter 5 or 20 bits in length (1 = On, 0 = Off), separated by commas, to allocate the Multimedia Broadcast Multicast Service Single Frequency Network (MBSFN) on the Multicast Channel (MCH). For the Subframe Allocation 1 frame and 4 frames, the Allocation Bitmap length is configured 5 bits and 20 bits, respectively. (If you enter fewer than 5 or 20 bits, 0 is inserted to fill in the remaining bits. And, the pattern of 1's and 0's is repeated in the remaining bits.) The Allocation Bitmap assigns the bits according to the Uplink Downlink configuration selected. Uplink subframes are not allocated .
: The 5 bits length bitmap is applied as follows:
The first/leftmost bit defines the MBSFN allocation for subframe #3, the second bit for #4, third bit for #7, fourth bit for #8, and the fifth bit for #9. Uplink subframes are not allocated and the last bit is not used.
: The 20 bits length bitmap is applied as follows:
Starting from the first radio frame and from the first/leftmost bit in the bitmap, the allocation applies to subframes #3, #4, #7 , #8, #9 in the sequence of the four radio-frames. Uplink subframes are not allocated and the last four bits are not used.
Example.
Waveform Generation Length = 2 Frames (20 ms)
Uplink Downlink Configuration = 5 (D,S,U,D,D,D,D,D,D,D)
Radio Frame Allocation Period = 2

N_1A_PRB becomes available and is set to 2.
Block Size 0 is set to 32.
Modulation Type is QPSK.
Channel Setup node, the following parameters are changed:
1. General Settings > Transmission Mode will be set to 2, if 2 or 4 antennas are selected.
3. Transmission Settings > RV Index Configuration is Manual (not editable).
Range of sequence length: 1 to 16

Set Auto MasterInformationBlock to On to make this parameter active.
This is the start number of the SFN (8 bits in binary, 2 bytes in hexadecimal).
If Auto MasterInformationBlock = On, SFN is incremented every 40 subframes (40 ms) and used for part of the payload data. For example, If you generate a 80 ms signal with Auto MasterInformationBlock set to On, the initial 40 ms of the SFN = SFN Start Number and the next 40 ms of the SFN = SFN Start Number +1.
If Auto MasterInformationBlock = Off, SFN is not incremented and the fixed value SFN Start Number is used for part of the payload data in each 40 subframes.
Refer to the 3GPP TS36.331.
Choice: Off | On
Default: On
Double-click or use the drop-down menu to turn the channel On or Off.
