Abstract
The present invention provides a scheduling signaling transmission method and device. The method includes: receiving, by UE, a random access response parameter sent by an eNB, where the random access response parameter is used to indicate that scheduling signaling of a random access response is transmitted through an E-PDCCH; and after sending a random access preamble to the eNB, receiving, by the UE through the E-PDCCH according to the random access response parameter, the scheduling signaling of the random access response. According to embodiments of the present invention, impact of inter-cell interference on scheduling signaling of an RAR can be reduced, thereby shortening a time delay of a random access process.
Claims20
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.
An evolved NodeB (eNB), comprising a transmitter, a receiver, a memory, and a processor that is separately connected to the transmitter, the receiver, and the memory, wherein the memory stores a group of program code, and the processor is configured to invoke the program code stored in the memory and perform:
- sending, by using the transmitter, a random access response (RAR) parameter to user equipment (UE), where 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 using the receiver, 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 of the RAR.
