A method for transmitting downlink control information, comprising: configuring, by a base station, available transmission resources of a plurality of types of long-term downlink control information, wherein in the plurality of types of long-term downlink control information, a subset relation exists between time domain resources of available transmission resources of at least two types of long-term downlink control information; and transmitting, by the base station, the plurality of types of long-term downlink control information on the available transmission resources of the plurality of types of long-term downlink control information, wherein the plurality of types of long-term downlink control information comprises at least two of following types of long-term downlink control information: a first type of long-term downlink control information, which is beam indication signaling or quasi-co-location relationship indication signaling; a second type of long-term downlink control information, which is activation signaling or deactivation signaling for transmitting a semi-persistent measurement pilot; and a third type of long-term downlink control signaling, which is activation signaling or deactivation signaling for reporting semi-persistent channel state information, wherein the long-term downlink control information refers to downlink control information having a longer effect on a transmission than short-term downlink control information, and the short-term downlink control information refers to downlink control information having a shorter effect on the transmission than the long-term downlink control information. configuring, by a base station, available transmission resources of a plurality of types of long-term downlink control information, wherein in the plurality of types of long-term downlink control information, a subset relation exists between time domain resources of available transmission resources of at least two types of long-term downlink control information; and transmitting, by the base station, the plurality of types of long-term downlink control information on the available transmission resources of the plurality of types of long-term downlink control information, wherein the plurality of types of long-term downlink control information comprises at least two of following types of long-term downlink control information: a first type of long-term downlink control information, which is beam indication signaling or quasi-co-location relationship indication signaling; a second type of long-term downlink control information, which is activation signaling or deactivation signaling for transmitting a semi-persistent measurement pilot; and a third type of long-term downlink control signaling, which is activation signaling or deactivation signaling for reporting semi-persistent channel state information, a first type of long-term downlink control information, which is beam indication signaling or quasi-co-location relationship indication signaling; a second type of long-term downlink control information, which is activation signaling or deactivation signaling for transmitting a semi-persistent measurement pilot; and a third type of long-term downlink control signaling, which is activation signaling or deactivation signaling for reporting semi-persistent channel state information, wherein the long-term downlink control information refers to downlink control information having a longer effect on a transmission than short-term downlink control information, and the short-term downlink control information refers to downlink control information having a shorter effect on the transmission than the long-term downlink control information.
