DL & UL Physical Channel in LTE

DL & UL Physical Channel in LTE shared channel system information signaling channel shared signaling physical ul physical dl physical channels.

How Physical channel of LTE works in UL & DL?A distinction has to made between: 

  • The Physical channel
  • The Physical signal
The DL physical channels are:
  • Physical DL Shared Channel (PDSCH)
  • It is a shared channel used to carry user data, radio & core network, system information (BCH),
  • paging message.
  • Physical DL Control Channel (PDCCH)
  • It is a shared signaling channel to carry the allocation of the resources (PDSCH).
  • Physical Broadcast Channel (PBCH)
  • It is the channel used to broadcast the system information.
The UL physical channels are:
  • Physical Random Access Channel (PRACH)
  • It is a shared channel used for the access procedure.
  • Physical UL Shared Channel (PUSCH)
  • It is a shared channel used to carry user data, radio & core network,
  • Physical UL Control Channel (PUCCH)
  • It is a shared signaling channel in uplink to allow the UE to request resources on the PUSCH.
