Physical downlink shared channel (PDSCH) is used to carry data from DSCH. In the downlink direction, the transmission channel DSCH can't exist independently, it can only exist with fach or DCH, so PDSCH, as the carrier of the transmission channel, can't exist independently. DSCH data can be encoded and combined in the physical layer, so TFCI can exist in PDSCH. However, SS and TPC are generally not used, and the power control and timing advance adjustment of UE are put on the accompanying PDCH channel.

Hello, dear!
It's nice to meet you in the community.
We're working on your problem. Please be patient.

Dear Friend!

In LTE the Downlink Shared Channel (DL-SCH) is a transport channel used for the transmission of user data, dedicated control and user-specific higher layer information and downlink system information. The Physical Downlink Shared Channel (PDSCH) is the physical channel that carries the DL-SCH coded data.

Downlink Transport Channels :LTE has 4 Downlink Logical Channels

- Broadcast Channel (BCH) : This LTE transport channel maps to Broadcast Control Channel (BCCH) and carries information like used for MIB and send information to Physical Broadcast channel (PBCH)

- Downlink Shared Channel (DL-SCH) This transport channel is the main channel for downlink data transfer. It is used by many logical channels like BCCH, CCCH, DCCH DTCH,MCCH,MTCH and send its information to Physical Downlink Shared Channel (PDSCH). The information carried by this channel is SIB, Data transfer

- Paging Channel (PCH) : To convey the PCCH information and mapped to Physical Downlink Shared Channel (PDSCH) and carries Paging Information

- Multicast Channel (MCH) : This transport channel is used to transmit MCCH information to set up multicast transmissions. This channel is mapped to Physical Multicast Channel (PMCH) this is basically used for MBMS services.
