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: A communication method and apparatus are provided. The method includes: A terminal device sends first data to a network device through a first cell group in an activated state. The terminal device receives a first message from the network device, where the first message is used to deactivate the first cell group. The terminal device changes a state of the first cell group from the activated state to a deactivated state based on the first message of the network device. If the terminal device receives no success acknowledgment of the first data and/or there is second data that has not been transmitted in the first cell group, the terminal device retransmits the first data and/or sends the second data to the network device through a second cell group in an activated state.

Abstract: This application provides a hybrid automatic repeat request HARQ codebook generation method and an apparatus. The method includes: A terminal device receives a first message from a network device, where the first message is for scheduling downlink data in a plurality of cells. The terminal device generates a HARQ codebook based on the first message. This application provides the HARQ codebook generation method for a case in which there are a plurality of scheduled cells. According to the foregoing method, transmission performance can be effectively ensured. For example, a transmission opportunity can be effectively increased, or a transmission error caused by poor channel quality can be effectively avoided, so that a flexible and variable service volume and/or communication requirement can be met.
