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.
