Title:
CONTROL CHANNEL TRANSMISSION METHOD, DEVICE AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/028532
Kind Code:
A1
Abstract:
Provided in the embodiment of the present invention are a transmission method, a device and a system for a downlink control channel. The downlink control channel comprises a first downlink control channel and a second downlink control channel, wherein the first downlink control channel comprises the first RS and a first DCI. A method for a user equipment to receive the downlink control channel comprises: obtaining a first RS time-frequency resource corresponding to the first RS; determining a first DCI time-frequency resource corresponding to the first DCI, according to the first RS time-frequency resource; detecting the first RS at the first RS time-frequency resource and using the first RS to demodulate the first DCI at the first DCI time-frequency resource; and determining a second time-frequency resource corresponding to the second downlink control channel according to the first DCI.
