Physical Channel Configuration (Part - II)

DL HS - PDSCH Information: 
This IE contains information about High Speed Physical Downlink Shared Channel.

• HS - SCCH Info: (High Speed - Shared Control Channel) The HS-SCCH is a fixed rate (60 kbps, SF=128) downlink physical channel used to carry downlink signalling related to HS-DSCH transmission
• HS - SCCH Channelisation Code Info
• 1 to MAX HS-SCCHs = 4 (At max UE can be configured to monitor 4 HS-SCCH channels simultaneously)
• Codes 0 to 127
• DL Scrambling Code:
• Generally DL scrambling Code for HS-SCCH & HS-PDSCH reception is same as Primary Scrambling Code (PSC), but NW may map HS-SCCH and HS-PDSCH channels on Secondary Scrambling Code (SSC), hence this IE is needed.
• Measurement Feedback Info: This IE is used to configure the measurement done by UE related to Quality of HS-PDSCH channel. Measurement are done by physical layer. This measurement is reported by Physical layer on UL HS-DPCCH channel to NW directly.
• Measurement Power Offset
• Feedback Cycle
• CQI Repetition Factor
• Delta CQI
• DL 64 QAM Configured:
• Boolean Variable to indicate if 64 QAM is configured or not.
• 64 QAM is basically used to increase DL data rate
• HS-DSCH TB Size Table: Used when MAC-ehs is configured
• OCTET Aligned or BIT Aligned

UL DPCH Info: 
This IE contains information about UL Dedicated Physical Channel.

• UL DPCH Power Control Information: Basically needed when Sync Procedure A or AA is needed.
• DPCCH Power Offset:
• When establishing the first DPCCH in CELL_DCH the UE shall start the UL inner loop power control at a power level according to:
• DPCCH_Initial_power = DPCCH_Power_offset – CPICH_RSCP
• Where
• DPCCH_Power_offset shall have the value of IE "DPCCH Power offset" in IE "Uplink DPCH power control info"
• The value for the CPICH_RSCP shall be measured by the UE.
• PC Preamble: 
• This IE gives number of Frames Npcp.
• This is basically used to introduce delay between DPCCH and DPDCH/E-DPCCH/E-DPDCH 
• The transmission of the uplink DPCCH power control preamble shall start Npcp radio frames prior to the radio frame where the uplink DPDCH/EDPCCH/E-DPDCH transmission starts, where Npcp is a higher layer parameter set by UTRAN
• The transmission start delay between DPCCH and DPDCH/E-DPCCH/E-DPDCH may be cancelled using a power control preamble of 0 length
• SRB Delay:
• To Delay the transmission on SRB0 to SRB4 by number of frames indicated in SRB Delay or while Physical channels are not considered established
• Power Control Algorithm
• Delta ACK
• Delta NACK
• ACK - NACK repetition factor
• Above three IEs are used to set the uplink HS-DPCCH power relative to DPCCH power
• HARQ Preamble Mode
• Scrambling Code Type - long or short
• Scrambling Code:
• Used to identify the UE in UL
• Number of DPDCH:
• MAX UL DPDCH = 6
• Value 0 may only be used if target configuration has no uplink DPDCH, i.e. E-DCH is configured
• Spreading Factor
• TFCI Existence
• No. of FBI Bits
• No. of TPC bits
• Puncturing Limit
