摘要：
The present invention discloses a method on a Long Term Evolution-Advanced (LTE-A) system backhaul link for demodulation pilot transmission, wherein the method includes that: among the resource areas occupied by a Relay-Physical Downlink Shared Channel (R-PDSCH) on the backhaul link, a base station selects the resource units which are preconfigured for sending the demodulation pilot signal of the R-PDSCH; the base station sends the demodulation pilot signal to a Relay Node (RN) belonging to the base station by using the selected resource units. The present invention also discloses a channel demodulation method on the LTE-A system backhaul link, an LTE-A communication system and device. The demodulation performance of the R-PDSCH in the LTE-A system can be ensured with the present invention.
