Dears,
I use 4E1 in one nodeB. Can i configure how many HS-PDSCH code?
Please help me.

Hi! It depends on few things.
Just an example with rough calculation. Imagine you have 3 users in one cell with HS Category 6 (3.6 Mbps, 5 codes, QPSK+16QAM).
Let it be everyone is served 80 % time with QPSK, 20% with 16QAM:
(1.6*0.8+3.6*0.2)*3 = 6 Mbps. So they consume all 4E1 in pipe and you need 15 codes for HS-DSCH.
Or users may be allocated one per cell at RBS with 3 cells. Again 4E1 is consumed but with 5 HS-DSCH per cell.

Thanks and reps are appreciated.
