DC with F1/F2 F2/F3 F3/F1 in Huawei

[fahmi]

Dear Huawei guys,

We have 3 carriers 2100 : F1 , F2 and F3.

DC work only with F1 and F2. no DC for F3.

Is there any way to activate DC also for F3 so we get F1/F2, F2/F3 ou F3/F1 in the same sector ?

Thanks

Did this worked ?? do you have this feature ?

Dear Kais,

Please to explain. Is that an optional feature ?

At huawei there are Flexible Dual Carrier function, with this function u can creat DC group from F1+F2, F1+F3, F2+F3.
at DC F1, F2, F3 co located sectors MUST BE at ONE resource group

Hi nofeartoday, please to explain. What is the Flexible Dual Carrier ? commands, parameters ...

System Capacity
This feature reduces the difference between the downlink load of cells in a multi-carrier cell
group. The effect of this feature depends on the number of DC-HSDPA UEs and their traffic
volume. A larger number of DC-HSDPA UEs and a larger traffic volume results in smaller
difference between the downlink load of cells.
Network Performance
Cells in a multi-carrier cell group have the same time offset (specified by the Tcell
(BSC6900,BSC6910) parameter). When multiple cells (three or four) served by the same RRU
in a sector transmit data at full power, the peak-to-average ratio (PAR) of the RRU increases if
a higher-order modulation scheme is used in the downlink. As a result, cell throughput may
decrease. On live networks, cells in the same sector do not transmit data at full power for a long
period of time, and therefore cell throughput only slightly decreases.
After Flexible Dual Carrier HSDPA is activated in networks with a low load, the data rates of
DC-HSDPA UEs increase because UEs can fully utilize frequency resources. As network load
increases, the gain provided by this feature decreases. The difference between the downlink load
of cells in a multi-carrier cell group before this feature is activated also affects the gain provided
by this feature. A larger difference results in a greater gain.
