Dedicated Transport Channels (**) Modes Directions PurposeDCH Dedicated FDD/TDD DL/UL Transfer of dedicated user information
(*) Requires in band identification of the UEs when particular UEs are addressed(**) UEs are identified by the physical channel, i.e. code and frequency for FDD and code, time slot and frequency for TDD
