E-UTRA Uplink Channel Structure TS36.321 Section 4.5 MAC specifications include the details about the mapping of logical channels onto transport channels, and TS36.212 Section 4 about the mapping of transport channels on physical channels.
Logical Channels:
๔บ Common Control Channel (CCCH)
โ For Idle Mode (RRC_IDLE) connection establishment (e.g., call setup, registration)
๔บ Dedicated Control Channel (DCCH)
โ For Connected Mode (RRC_CONNECTED) signaling
๔บ Dedicated Traffic Channel (DTCH)
โ For Connected Mode (RRC_CONNECTED) user data traffic
Transport Channels:
๔บ Random Access Channel (RACH)
โ Uplink random access
๔บ Uplink Shared Channel (UL-SCH)
โ Signaling and traffic are multiplexed onto UL-SCH
Physical Channels:
๔บ Physical Random Access Channel (PRACH)
๔บ Physical Uplink Control Channel (PUCCH)
โ For carrying physical control information โ Uplink control information (UCI) if PUSCH is not configured
๔บ Physical Uplink Shared Channel (PUSCH)
โ For carrying dedicated control/traffic as well as UCI
