Claim:
1. A method for receiving reference signals (RSs) transmitted from a user equipment (UE) in a communication system including a Node B, a transparent-relay node (T-RN), and the UE, the method comprising the steps of: signaling by the Node B, RS transmission parameters to the UE; receiving, by the Node B, an RS for the UE transmitted from the UE; and estimating, by the Node B, a channel state information (CSI) metric based on the RS for the UE, wherein the T-RN obtains the RS transmission parameters either through separate signaling from the Node B or through the same signaling it is informed from the Node B to the UE, wherein the T-RN discontinues the transmission of a transport block (TB) to the Node B at a transmission symbol determined from the transmission symbol the UE transmits the RS and the time required for the T-RN to switch from transmitting the TB to receiving the RS, and wherein the T-RN is a decode and forward relay node that shares a same physical cell identity as the Node B.
