Uplink Physical Channel

Deicate uplink physical channels

here are three types of uplin" dedicated physical channels, the uplin" DedicatedPhysical Data Channel 2uplin" DPDCH3, the uplin" Dedicated Physical Control Channel2uplin" DPCCH 3, and the uplin" Dedicated Control Channel associated with HS#DSCHtrans*ission 2uplin" HS#DPCCH 3!

he DPDCH, the DPCCH and the HS#DPCCH are +-' code *ultiple0ed!

he uplin" DPDCH is used to carry the DCH transport channel!

he uplin" DPCCH is used to carry control infor*ation generated at 4ayer %! he 4ayer %control infor*ation consists of "nown pilot 5its, trans*it power#control 2PC3 co**ands,

feed5ac" infor*ation 26/+3, and transport#for*at co*5ination indicator 26C+3!

Deicate ownlink physical channels

here is only one type of downlin" dedicated physical channel, the Downlin" DedicatedPhysical Channel 2downlin" DPCH3!

7ithin one downlin" DPCH, dedicated data generated at 4ayer 8 and a5ove, i!e! thededicated transport channel 2DCH3, is trans*itted in ti*e#*ultiple0 with controlinfor*ation generated at 4ayer % 2"nown pilot 5its, PC co**ands, and an optional

6C+3! he downlin" DPCH can thus 5e seen as a ti*e *ultiple0 of a downlin" DPDCH anda downlin" DPCCH!

Co##on ownlink physical channels

he High Speed Physical Downlin" Shared Channel 2HS# PDSCH3 is used to carry the HighSpeed Downlin" Shared Channel 2HS#DSCH3! A HS#PDSCH corresponds to onechanneli9ation code of :0ed spreading factor S6;%) fro* the set of channeli9ation codesreserved for HS#DSCH trans*ission! Multi#code trans*ission is allowed, which translatesto U 5eing assigned *ultiple channelisation codes in the sa*e HS#PDSCH su5fra*e,

depending on its U capa5ility!

he HS#SCCH is a :0ed rate 2)< "5ps, S6;%8=3 downlin" physical channel used to carrydownlin" signalling related to HS#DSCH trans*ission! 6igure 8)A illustrates the su5#fra*estructure of the HS#SCCH!
