This TS describes the characteristics of eNB-Relay node transmissions. From a UE perspective a relay node is part of the radio access network and behaves like an eNB. A relay node is wirelessly connected to a donor eNB.
A relay node includes at least two physical layer entities. One entity is used for communication with UEs. Another physical layer entity is used for communication with the donor eNB and it corresponds to UE functionality. If a relay node is configured to use relay-specific advancements, the physical layer entity for communication with the donor eNB corresponds to UE functionality extended by relay-specific advancements.
