Abstract

The present application discloses methods and devices for determining a downlink resource set and sending resource position information, and particularly relates to a method for determining, by a terminal, a downlink control channel resource set, a method for sending, by a base station, a position related to a downlink control channel resource set, and related devices. A terminal obtains, in a predefined manner and/or by receiving a notification of a base station, a frequency domain position and a time domain position of a downlink control channel resource set corresponding to the terminal, so as to determine that the downlink control channel resource set corresponding to the terminal is a third downlink control channel resource set. The base station transmits a common downlink control channel and/or a terminal-dedicated downlink control channel on the frequency domain and time domain positions of the downlink control channel resource set determined by the terminal.
