Abstract
A method and a device for detecting downlink control information. The method includes: a Relay Node (RN) receiving control information born in a Relay Physical Downlink Control Channel (R-PDCCH) sent by an evolved Node B (eNB) to acquire a control resource; the RN performing detection on the control resource according to an index of the control resource to acquire own control information; wherein the control resource is a Relay Control Channel Element (R-CCE) or a Physical Resource Block (PRB). System overhead can be saved and system transmission efficiency can be improved.
