Shared HSDPA Scheduler for Baseband EfficiencyRAS06
Peak rate of 10.8 Mbps is shared dynamically between sectorsEfficient utilization of resources since the peak rate of 10.8 Mbps is only seldom available in macro cells due to interference

3.6 Mbps 10.8 Mbps
0 Mbps (no HSDPA mobiles)
7.2 Mbps

0 Mbps (no HSDPA mobiles)
3.6 Mbps 0 Mbps (no HSDPA mobiles)
Throughput shared equally between all
sectors
HSDPA mobiles only in single
sector
Throughput shared between two
sectors
Instantaneous adaptation according to throughput per sector

RAS05.1: HSDPA BTS Configuration Options for Ultra
1. Basic HSDPA • QPSK/16 QAM• Max 5 codes per cell• 16 Users per BTS • Up to 3.6 Mbps per BTS• 32 CE from WSPC allocated to HSDPA
scheduler• 1 scheduler with 1-3 cells per BTS• Cells can be on different frequencies
(e.g.., 2-omni or in later SW releases 3-omni, 2+1)16 users
16 users16 users
8 users
4 users4 users
Example 1: 16 users per BTS1*32 CE
Example 2: 16 users per cell3*32 CE =96
2. 16 Users per cell• Up to 3.6 Mbps per cell• Max 5 codes per cell• Each HSDPA cell requires 32 CE from
WSPC if allocated to HSDPA

WCDMA ULTRA BTS Base Band DimensioningExample for 1+1+1/ HSDPA activation
• Note that the table describes only BTS Baseband dimensioning. In practice also Iub, Air interface, etc has to be taken into account. Please see RAS dimensioning guide for more information.
• CEs required for associated HSDPA UL is not included in the table• Common Channels not included• 5 code phones assumed to be used in NW. Figures in (brackets) assumes 10 code phones
and figures in [brackets] assumes 15 code phones are used in NW

• Number of HSUPA resource steps allocated to get certain combined BTS baseband L1 throughput with certain number of UEs:
• Example: to get 4.2 Mbps combined (of all UEs) L1 throughput with 12 users, 3 HSUPA resource steps are needed i.e. Resource steps 1-3 (32 CE + 16 CE + 16 CE = 64 CE)• UEs Peak Throughput depends on how many simultaneous UEs there is in each HSUPA resource step at a time:
• 1-2 UEs in one HSUPA resource step: 2 Mbps peak rate per UE
• 3-4 UEs in one HSUPA resource step: 1.4 Mbps peak rate per UE
• 5-8 UEs in one HSUPA resource step: 384 kbps - <1.4 Mbps peak rate per UE
