发明名称 PHYSICAL UPLINK SHARED CHANNEL DEMODULATION REFERENCE SIGNAL DESIGN FOR UPLINK COORDINATED TRANSMISSION IN TYPE II RELAY
摘要 <p>A method is provided for an access node to perform channel estimation. The method includes, when a UE and a relay node are present in a cell with the access node, the access node receiving from the UE and from the relay node DMRS that are cyclically shifted relative to one another. The method further includes the access node performing a first channel estimation based on the DMRS that was transmitted by the UE, performing a second channel estimation based on the DMRS that was transmitted by the at least one relay node, combining the first channel estimation with the second channel estimation to derive a combined channel estimation, using the first channel estimation to demodulate control information received from the UE, and using the combined channel estimation to demodulate data received from both the UE and the at least one relay node.</p>
