The present invention discloses a method and device for resource allocation of backhaul link control channel information. Upon application of a technical solution proposed by embodiments of this invention and based on the condition of introducing DMRS and CSI-RS, make remaining REs which are not occupied by CSI-RS and/or DM-RS in OFDM symbol that contains REs for transmitting CSI-RS and/or DM-RS constitute REG to transmit backhaul link control channel information or abandon them; thus, on the basis of maximizing the reservation of existing LTE system specification, specifying resource allocation scheme of backhaul link control channel information in corresponding physical resource block, giving consideration to both simple specification design and full utilization of resources, and realizing flexible design and allocation in light of the demand of a real system.
