Abstract
An answer information feedback method includes steps of: with respect to a current uplink subframe of a primary carrier in a TDD mode, determining, by a terminal, a downlink subframe of a secondary carrier in an SDL mode and corresponding to the current uplink subframe in answer information feedback as a to-be-fed-back downlink subframe, the to-be-fed-back downlink subframe being determined from designated downlink subframes of the secondary carrier in accordance with a downlink retransmission timing mode for a DL-reference UL/DL configuration of the secondary carrier, the designated downlink subframes including downlink subframes except a downlink subframe having a location identical to an uplink subframe indicated by the DL-reference UL/DL configuration, the DL-reference UL/DL configuration being identical to a timeslot configuration of the primary carrier; and transmitting answer information for the to-be-fed-back downlink subframe to a network side using the current uplink subframe.
