Abstract: This application relates to the field of communications technologies, and discloses a communication method and apparatus. The method includes: when a terminal device determines transmission statuses of N time-frequency resource groups based on transmission indication information sent by a network device, if a time-frequency resource group is separated into a former half and a latter half by one or more first symbols in time domain, the former half of the time-frequency resource group may be combined into a previous time-frequency resource group of the time-frequency resource group, or the latter half of the time-frequency resource group may be combined into a next time-frequency resource group of the time-frequency resource group, to determine a transmission status. This ensures continuity, in time domain, of the time-frequency resource group indicated by the transmission indication information, and can avoid unnecessary uplink transmission cancellation or downlink transmission interruption, thereby increasing a network capacity.

Abstract: An information indication method is provided, including: A terminal-side device receives first higher layer signaling from a network-side device, where the first higher layer signaling is used to configure N bandwidth parts BWPs, and N is a positive integer. The terminal-side device receives downlink control information from the network-side device, where the downlink control information includes an indication field. When N is less than a maximum quantity of BWPs that can be configured through the first higher layer signaling when the terminal-side device is in a connected mode (for example, an RRC connected mode) or a maximum quantity of BWPs that can be determined by using candidate bit states of the indication field that is used to determine an active BWP and that is in the downlink control information, the indication field indicates a position of the active BWP located in an initial BWP and the N BWPs.

Abstract: A radio access network device configures a first parameter and location indication information for a first terminal device. The first parameter is used to determine a data transmission resource of the first terminal device. The location indication information indicates a location of first retransmission scheduling information corresponding to the first terminal device in retransmission scheduling information. Then, the first terminal device sends uplink data to the radio access network device, and the radio access network device receives the uplink data. Afterwards, the radio access network device sends the retransmission scheduling information to the first terminal device. The first terminal device determines a retransmission resource based on the retransmission scheduling information, the location indication information, and the first parameter. Finally, the first terminal device retransmits the uplink data to the radio access network device by using the retransmission resource.
