Abstract: This application provides example downlink control information transmission methods and apparatuses. In an example method, a terminal device receives first configuration information. The first configuration information may indicate the terminal device to monitor a physical downlink control channel (PDCCH) candidate in a first scheduling cell and a second scheduling cell. The PDCCH candidate is used to carry downlink control information for scheduling data transmission in a same scheduled cell. The terminal device determines, for the same scheduled cell, monitoring upper limits of the PDCCH candidate in a first unit time and a second unit time. The first unit time is determined based on a subcarrier spacing of an active downlink bandwidth part in the first scheduling cell, and the second unit time is determined based on a subcarrier spacing of an active downlink bandwidth part in the second scheduling cell.

Abstract: This application provides a control information transmission method, a base station, and a terminal. The method includes: extracting a radio resource from a preset resource block set, and sending control information in a first time period by using the radio resource. The base station includes a processor and a transmitter. The processor is configured to extract a radio resource from a preset resource block set, and the transmitter is configured to send control information in a first time period by using the radio resource. According to the control information transmission method provided in this application, the base station can send the control information in any time period, and the terminal can receive the control information in any time period, thereby shortening a time interval between two control information transmissions.

Abstract: A communication method and apparatus includes: a network device separately sends configuration parameters of power saving signaling to terminal devices. Then, the network device sends downlink control information carrying the power saving signaling to the terminal device through a physical downlink control channel based on a payload of the DCI and/or a search space set. The configuration parameter of the power saving signaling includes the payload of the DCI and the search space set. The payload of the DCI indicates a quantity of bits of the DCI. The DCI is used to carry the power saving signaling and is transmitted through the physical downlink control channel (PDCCH). The search space set is used to determine a monitoring occasion of the PDCCH.
