Abstract
The invention discloses a method for transmitting and receiving downlink control information, a serving node and a user equipment. The method comprises: determining, by a serving node of a interfered UE, a protected resource, wherein the protected resource is located in at least one of the followings: a physical resource corresponding to a USS in a PDCCH, a physical resource corresponding to an expanded CSS in the PDCCH, a physical resource corresponding to a USS in an E-PDCCH or a physical resource corresponding to a CSS of the E-PDCCH; transmitting, by the serving node, first downlink control information of an interfered cell on the protected resource, wherein the first downlink control information comprises scheduling information for scheduling a paging message and/or a SIB1 message of the interfered cell. The invention can reduce the interference to a system broadcast message, a paging message and the like in a heterogeneous network.
