Title:
METHOD FOR TRANSMITTING CONTROL INFORMATION, RELATED DEVICE, AND COMPUTER STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2018/202164
Kind Code:
A1
Abstract:
Provided are a method for transmitting control information, a related device, and a computer storage medium. The method comprises: a network apparatus determining configuration information of a control channel, wherein the configuration information comprises at least one of frequency domain information and time domain information which indicate a time-frequency resource occupied by the control channel and indication information indicating one or more resource unit sets, and the time-frequency resource occupied by the control channel comprises the one or more resource unit sets; the network apparatus mapping, according to the configuration information, control information to one or more resource unit sets in the one or more resource unit sets; and the network apparatus transmitting the configuration information to a terminal apparatus, and transmitting the control information to the terminal apparatus. The present invention enables a terminal apparatus to perform joint channel estimation according to all reference signals in a resource unit set, such that a quantity of reference signals used for channel estimation is increased, thereby enhancing accuracy of channel estimation without increasing a density of reference signals.
