User throughput
HSDPA uses downlink shared channel.
Downlink data is scheduled in 2 ms TTIs to users.
User throughput depends upon the number of active HSDPA users in thecell/BTS.

Mac-hs is located in the Node B to allow rapid re-transmission of NRT data
Mac-d is responsible for:
mapping between logical channels and transport channels; selection of appropriate Transport Format priority handling identification of UEs on common transport channels multiplexing/demultiplexing of upper layer PDUs traffic volume measurement; transport Channel type switching; ciphering for transparent mode RLC

Multiple HS-SCCH channels One for each simultaneously

HS-PDSCH codes divided for differenttransport blocks.
Multiple simultaneous transport blocksto one UE not possible.

STRATEGY:1) The ratio between PC headroom and Variable Power shall remain the same after the introduction of HSDPA becauseHSDPA does not require any power control headroom
2) When HSDPA power is allocated DCH Power increases to to keep BLER targets, so in order to avoid HSDPA power to beallocated and soon released DCH power increase

Deployment Strategy-Co-existence of R'99 and R5 HSDPA
Case 1: Carrier shared between R5 HSDPA and R'99
Operator definable resource sharing between R5 HSDPA
and R'99. Most likely initial network setup:
cost efficiency
Simple parameter planning (traffic handling)
Capacity (additional load from HSDPA) Impact existing R'99 performance (Ec/No quality
degradation)
F1 (R99+R5)F1 (R99+R5)
= R5 HSDPA + R5 DCH= R'99 DCH

Deployment Strategy- Dedicated Carrier for HSDPA
F1 R99F1 R99
F2 R5F2 R5
Case2: Dedicated R5 (HSDPA+DCH) carrier
R5 UE (HSDPA + DCH) directed to R5 HSDPA
carrier Recommended for hotspot, indoor, majorcorporate customer office etc.
Minimum Impact to existing system (capacity andperformance) than case 1.
Guarantee certain level of HSDPA performance More complex parameter planning (DRRC, UE
capability, IFHO)
Control to have only R5 (HSDPA + DCH) on f2(trigger point for inter-Frequency HO for realtime
etc.)
= R5 HSDPA + R5 DCH= R'99 DCH

Concern:
If a HSDPA UE performs IFHO from f2 to f1, the UE cannot get HSDPA allocation again in f1 during the call. It has to
disconnect and re-establish the RRC setup for PS call (using HSDPA DRRC) in order to get HSDPA allocation again.
This is due to current HSDPA resumption timer works only within the same layer with HSDPA enabled cells.

Assumption F1 (HSDPA disabled), F2( HSDPA enabled)
HSDPA DRRC This brings Rel5 UE to F2, and Rel99 UE to F1 during RRC Con Setup.
ISHO / ISCR ISHO is only allowed from F1 to 2G.
RT: RSCP (-105dBm) & Ec/No (-12dB) NRT: RSCP (-115dBm)
ISHO from F2 not allowed. It will first move down to F1, since F1 has continuouscoverage.
ISCR is also allowed from F1 to 2G, since F2 does not have ADJG to 2G. IFHO / IFCR
IFHO is only allowed from F2 to F1 RT: RSCP (-95dBm) & Ec/No (-12dB) NRT: RSCP (-95dBm)
IFCR is also allowed from F2 to F1 only, since no ADJI from F1 to F2 defined. Neighbor Planning

RNP parameter in RNC. Timer started when HSDPA
capable UE having DCH NRTenters into HSDPA capable cell
and Active set size=1.
Switching to HS-DSCH is triedafter the timer expires, if theActive set size is still 1.
Switching happens viaDCH0/0.
Normal HSDPA selection
procedure is applied after acapacity request, whenDCH0/0 is allocated.
