Abstract: Embodiments of the present disclosure provide a message feedback method and apparatus for carrier aggregation. The method includes: receiving, by a terminal in a first downlink subframe on a carrier aggregation group, a data packet sent by a base station, where the carrier aggregation group includes a first carrier and a second carrier; determining a first timing, based on a subframe configuration for the carrier aggregation group and a mapping relationship between subframe configurations for carrier aggregation groups and timings; determining a first uplink subframe from subframes on the carrier aggregation group based on the first timing; and sending, to the base station, a feedback message in the first uplink subframe. In this way, the first uplink subframe is determined on the entire carrier group for sending the feedback message, and a selectable range is larger.

Abstract: This application relates to the field of communication technologies, and provides a communication method and apparatus. The method includes: A terminal device receives first downlink control information DCI from a network device through a first physical downlink control channel PDCCH. The first DCI includes a first time domain resource assignment TDRA indicator field, and the first TDRA indicator field is used to indicate a first time domain resource. The terminal device receives or sends data on a second time domain resource after determining the second time domain resource based on a time domain position of the first PDCCH and the first time domain resource. The first time domain resource is different from the second time domain resource. The method is applied to a time domain resource assignment process of the data scheduling.
