Claim:
1. A scheduling signaling transmission method, comprising: sending, by an evolved NodeB (eNB), a random access response (RAR) parameter to user equipment (UE), wherein the RAR parameter is used to indicate that scheduling signaling of a RAR is transmitted through an enhanced physical downlink control channel (E-PDCCH); and receiving, by the eNB, a random access preamble sent by the UE, and sending the scheduling signaling of the RAR through the E-PDCCH according to the random access preamble, so that the UE receives, through the E-PDCCH according to the RAR parameter after sending the random access preamble, the scheduling signaling that is of the RAR and that is sent by the eNB, wherein the eNB is a target eNB, and the sending, by an eNB, a RAR parameter to UE comprises: sending, by the target eNB, a handover request acknowledge message to a target mobility management entity (MME), so that the target MME sends a forward relocation response to a source MME after receiving the handover request acknowledge message, the source MME sends a handover command to a source eNB after receiving the forward relocation response, and the source eNB sends a handover command to the UE after receiving the handover command sent by the source MME, wherein the handover command sent by the source eNB, the handover command sent by the source MME, the forward relocation response, and the handover request acknowledge message all comprise the RAR parameter.
