There are two kinds of type of relay in LTE system, One is Type I and the second Type II,  I check all the  3GPP standards including 36.331, 36.321 and 36.323.  but no one place to describe how to transfer the data between DeNB and UE in RN.  I want to know more  detailed descriptions about how RN transfer the data between DeNB and UE.  Anyone else know why.  thanks in advance.
