Table 3 Characteristics of Type 1 and Type 2 RN's

From: Overview of enabling technologies for 3GPP LTE-advanced

Type Functions and characteristics
Type 1 · It controls a cell, which appears to a UE as a separate cell distinct from the donor
  · The cell shall have its own physical cell identity and the RN shall transmit its synchronization channels and reference symbols
  · In the context of single-cell operation, the UE shall receive scheduling information HARQ feedback directly from the RN and send its control channels to the RN
  · It shall appear as an eNB to release 8 UE's (i.e., be backwards compatible)
  · To the LTE-Advanced UE's, it should be possible for a Type 1 RN to appear differen than release 8 eNB to allow for further performance enhancement
Type 2 · It does not have a separate physical cell identity and thus would not create any new cell
  · It is transparent to release 8 UE's; a release 8 UE is not aware of the presence a Type 2 RN
  · It can transmit PDSCH
  · It does not transmit CRS and PDCCH
