Method for Sending Control Information, User Equipment, and Base Station

A base station, comprising:

• a processor;
• and
• a non-transitory computer readable storage medium storing a program for execution by the processor, the program including instructions to:
• send a plurality of pieces of downlink control information to a user equipment, wherein pieces of the plurality of pieces of downlink control information carry downlink assignment indexes, and wherein a first piece of the plurality of pieces of downlink control information further carries a total downlink assignment indexes;
• receive a hybrid automatic repeat request response message sent by the user equipment according to the total downlink assignment indexes, according to downlink assignment indexes of the pieces of the plurality of pieces of downlink control information, and according to physical downlink shared channels corresponding to the pieces of the plurality of pieces of downlink control information;
• and
• obtain, according to the hybrid automatic repeat request response message, response information for a physical downlink shared channel corresponding to the pieces of the plurality of pieces of downlink control information;
• and
• wherein the downlink control information comprises first downlink control information and second downlink control information;
• wherein the downlink assignment indexes indicate indexes of physical downlink shared channels corresponding to downlink control information carrying the downlink assignment indexes, indicate indexes of physical downlink control channels indicating downlink semi-persistent scheduling release, or indicate indexes of physical downlink shared channels corresponding to downlink control information carrying the downlink assignment indexes and a physical downlink control channel indicating downlink semi-persistent scheduling release;
• and
• wherein the total downlink assignment indexes is a quantity of physical downlink shared channels corresponding to the downlink control information, a quantity of physical downlink control channels indicating downlink semi-persistent scheduling release, or a sum of a quantity of physical downlink shared channels corresponding to the downlink control information and a quantity of physical downlink control channels indicating downlink semi-persistent scheduling release.

A method comprising:

• receiving, by a user equipment, a plurality of pieces of first downlink control information sent by a base station, wherein pieces of the plurality of pieces of first downlink control information carry downlink assignment indexes, and wherein at least one piece of the plurality of pieces of first downlink control information further carries a total downlink assignment indexes;
• generating, by the user equipment, a hybrid automatic repeat request response message according to the total downlink assignment indexes, according to the downlink assignment indexes of the pieces of the plurality of pieces of first downlink control information, and according to a physical downlink shared channel corresponding to the pieces of the plurality of pieces of first downlink control information;
• and
• sending, by the user equipment, the hybrid automatic repeat request response message to the base station;
• and
• wherein the downlink assignment indexes indicate indexes of physical downlink shared channels corresponding to downlink control information carrying the downlink assignment indexes, indicate indexes of a physical downlink control channel indicating downlink semi-persistent scheduling release, or indicate indexes of physical downlink shared channel corresponding to downlink control information carrying the downlink assignment indexes and physical downlink control channels indicating downlink semi-persistent scheduling release;
• and
• wherein the total downlink assignment indexes is a quantity of physical downlink shared channels corresponding to the downlink control information, a quantity of physical downlink control channels indicating downlink semi-persistent scheduling release, or a sum of a quantity of physical downlink shared channels corresponding to the downlink control information and a quantity of physical downlink control channels indicating downlink semi-persistent scheduling release.

A method comprising:

• sending, by a base station, a plurality of pieces of downlink control information to a user equipment, wherein pieces of the plurality of pieces of downlink control information carry downlink assignment indexes, and wherein at least one piece of the plurality of pieces of downlink control information further carries a total downlink assignment index;
• receiving, by the base station, a hybrid automatic repeat request response message sent by the user equipment, according to the total downlink assignment index, according to a downlink assignment index of the pieces of the plurality of pieces of downlink control information, and according to a physical downlink shared channel corresponding to the pieces of the plurality of pieces of downlink control information;
• and
• obtaining, by the base station, according to the hybrid automatic repeat request response message, response information for physical downlink shared channels corresponding to the pieces of the plurality of pieces of downlink control information;
• wherein the downlink control information comprises first downlink control information and second downlink control information;
• wherein the downlink assignment indexes indicate indexes of physical downlink shared channels corresponding to downlink control information carrying the downlink assignment index, indicate indexes of physical downlink control channels indicating downlink semi-persistent scheduling release, or indicate indexes of physical downlink shared channels corresponding to downlink control information carrying the downlink assignment indexes and a physical downlink control channel indicating downlink semi-persistent scheduling release;
• and
• wherein the total downlink assignment index is a quantity of physical downlink shared channels corresponding to the downlink control information, a quantity of physical downlink control channels indicating downlink semi-persistent scheduling release, or a sum of a quantity of physical downlink shared channels corresponding to the downlink control information and a quantity of physical downlink control channels indicating downlink semi-persistent scheduling release.
