Title:
METHOD AND DEVICE FOR CONTROLLING TRANSMISSION OF DOWNLINK CONTROL CHANNELS HAVING SHORT TTIS
Document Type and Number:
WIPO Patent Application WO/2018/024098
Kind Code:
A1
Abstract:
Embodiments of the present disclosure provide a method and device for controlling transmission of downlink control channels having short TTIs. The method comprises: a base station determines transmission positions of one or more downlink control channels having short TTIs, the transmission positions comprising transmission in a conventional control region of an LTE system or transmission in a control region having a short TTI; and the base station notifies a terminal of transmission positions of downlink control channels having short TTIs, and the terminal detects the downlink control channels at the transmission positions of the corresponding control channels, or the terminal can also determine the transmission positions of one or more downlink control channels having short TTIs by means of blind detection.
