Following rules applied to subframes that are not subframe0 and subframe5 (subframe9 without paging)
For normal cyclic shift (7 OFDM symbols in a slot)
antenna port 0 and antenna port 1 occupied REs in 1 PRB for 1 codeword excluding PDCCH and PCFICH is 12 REs
antenna port 2 and antenna port 3 occupied REs in 1 PRB for 1 codeword excluding PDCCH and PCFICH is 8 REs
antenna port 5 occupied REs in 1 PRB for 1 codeword is 12 REs
antenna port 15 and antenna port 16 occupied REs in 1 PRB is 2 REs
antenna port 7 and antenna port 8 occupied REs in 1 PRB is 12 REs
For TM3 2x2 10MHz CFI=1
Number of available REs is 7200
1 codeword with 64QAM modulation, bits rate is 7200 * 6 = 43200 bits/msec
2 codeword with 64QAM modulation, bits rate is 7200 * 6 * 2 = 86400 bits/msec
For TM4 4x2 (4x4) 10MHz CFI=1
Number of available REs is 7200 - 400 = 6800
1 codeword with 64QAM modulation, bits rate is 6800 * 6 = 40800 bits/msec
2 codeword with 64QAM modulation, bits rate is 6800 * 6 * 2 = 81600 bits/msec
For TM9 2x2 10MHz CFI=1
For non-CSI-RS subframes
Number of available REs is 7200 - 600 = 6600
1 codeword with 64QAM modulation, bits rate is 6600 * 6 = 39600 bits/msec
2 codeword with 64QAM modulation, bits rate is 6600 * 6 * 2 = 79200 bits/msec
For CSI-RS subframes
Number of available REs is 7200 - 600 - 100 = 6500
1 codeword with 64QAM modulation, bits rate is 6500 * 6 = 39000 bits/msec
2 codeword with 64QAM modulation, bits rate is 6500 * 6 * 2 = 78000 bits/msec
For TM9 4x2 (4x4) 10MHz CFI=1
For non-CSI-RS subframes
Number of available REs is 7200 - 600 - 400 = 6200
1 codeword with 64QAM moudulation, bits rate is 6200 * 6 = 37200 bits/msec
2 codeword with 64QAM modulation, bits rate is 6200 * 6 * 2 = 74400 bits/msec
For CSI-RS subframes
Number of available REs is 7200 - 800 - 400 - 100 = 6100
1 codeword with 64QAM moudulation, bits rate is 6100 * 6 = 36600 bits/msec
2 codeword with 64QAM modulation, bits rate is 6100 * 6 * 2 = 73200 bits/msec
For subframe0 and subframe5, PBCH, PSS and SSS would take away some REs.
PBCH would occupy extra 72 * 4 - (4 * 6) - (4 * 6)= 240REs
PSS and SSS would occupy extra 72 * 2 = 144REs
Note: for subframe0, TM3 2x2 total available REs for PDSCH is equal to 7200 - 240 - 144 -24 = 6792REs
