Communication processing method, device and system for uplink and downlink separation

The present invention provides a communication processing method, device and system for uplink and downlink separation. The communication processing method comprises: sending scheduling information to User Equipment (UE) and a second communication node; receiving feedback information sent from the second communication node, wherein the feedback information corresponds to information sent from the UE and is sent from the second communication node after the second communication node receives, according to the scheduling information, the information sent from the UE according to the scheduling information. By sending the scheduling information to the UE and the second communication node, and after the second communication node receives the information corresponding to the scheduling information sent from the UE, the communication processing method for the uplink and downlink separation provided in the present invention enables the second communication node to send the feedback information corresponding to the information to a first communication node, and then enables the first communication node to obtain the communication integrity between the UE and the first communication node or the UE and the second communication node by the received feedback information, thus improving the reliability of the communication.
