Not able to use 15th Code in HSDPA E*******?

[ltecity]

We have E// equipments and in our HSDPA network not able to use 15th HSDPA code?

Any Reason?

We have licence 45 codes and max code 15 and dynamic code allocation is also yes.

Any commnet on this?

You need some codes for EUL downlink signalling: thus, you can get max 14 codes for HSDPA.

In order to show advertised downlink speeds, you have to turn off EUL, use max one user per TTI (and cell....) and
test with UDP source. (TCP can not send enough ACKs on 384 kbit/s uplink).
Of course, this is not for any real cell with real users.

You need to check whether you have hsupa or not, if you have hsupa, so you only have 14, also check your hsscch code, to achieve max hspdsch code, its better to use 2 hsscch code instead of 4 hsscch.

Hi,
If you have a separate carrier for HSPDA (R99 limited) you can theoretically achieve 15codes, but you have to limit signaling to gain another branch of code tree: set numHsScchCodes=1 or 2, but with this setting only 1 or 2 users can be served in the same TTI.
