Abstract
Embodiments of the present disclosure provide an apparatus configured to receive one or more pieces of first downlink control information from a base station, where each of the one or more pieces of first downlink control information carries a downlink assignment index, and at least one of the one or more pieces of first downlink control information carries a total downlink assignment index, generate a hybrid automatic repeat request response message according to the total downlink assignment index and downlink assignment indexes of the one or more pieces of first downlink control information, and send the hybrid automatic repeat request response message to the base station.
Claims17
An apparatus, comprising:
- a memory comprising instructions;
- and
- one or more processors in communication with the memory, wherein the one or more processors execute the instructions to perform steps of:
- receiving one or more pieces of first downlink control information from a base station, wherein each of the one or more pieces of first downlink control information carries a downlink assignment index, and at least one of the one or more pieces of first downlink control information further carries a total downlink assignment index;
- generating a hybrid automatic repeat request response message according to the total downlink assignment index and the downlink assignment index of each of the one or more pieces of first downlink control information;
- and
- sending the hybrid automatic repeat request response message to the base station using a physical uplink control channel format 4 or a physical uplink control channel format 3 based on whether a quantity of carriers configured for the apparatus exceeds a carrier quantity threshold, wherein
- each downlink assignment index indicates an index of a physical downlink shared channel corresponding to a piece of first downlink control information carrying a respective downlink assignment index, or indicates an index of a physical downlink control channel indicating downlink semi-persistent scheduling release, or indicates an index of the physical downlink shared channel corresponding to the piece of first downlink control information carrying the respective downlink assignment index and the physical downlink control channel indicating downlink semi-persistent scheduling release, and
- the total downlink assignment index is a quantity of physical downlink shared channels corresponding to a total quantity of pieces of downlink control information sent by the base station to the apparatus, the total quantity of pieces of downlink control information comprising the one or more pieces of first downlink control information received by the apparatus, or is a quantity of physical downlink control channels indicating downlink semi-persistent scheduling release, or is a sum of the quantity of the physical downlink shared channels corresponding to the total quantity of pieces of downlink control information and the quantity of physical downlink control channels indicating downlink semi-persistent scheduling release.
