SCHEDULING SIGNALING TRANSMISSION METHOD AND DEVICE

摘要

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.

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.
