Component carrier grouping method and device

A method, comprising:

• receiving, by a terminal, first grouping configuration information sent by a network device, wherein the first grouping configuration information indicates a grouping result of at least one component carrier group of a first type;
• receiving, by the terminal, control information corresponding to a first component carrier that is sent by the network device over a second component carrier, wherein the first component carrier and the second component carrier belong to a same component carrier group of the at least one component carrier group of the first type;
• when a first plurality of component carriers in at least two component carrier groups of the at least one component carrier group of the first type are scheduled, aggregating, by the terminal, feedback information corresponding to the first plurality of component carriers, and feeding back the aggregated feedback information to the network device over one component carrier;
• receiving, by the terminal, second grouping configuration information sent by the network device, wherein the second grouping configuration information indicates a grouping result of at least one component carrier group of a second type, and wherein there is an intersection set between each component carrier group of the at least one component carrier group of the first type and the at least one component carrier group of the second type;
• and
• sending, by the terminal, feedback information corresponding to each component carrier in each component carrier group of the at least one component carrier group of the second type to the network device over a primary component carrier or one component carrier in the component carrier group of the second type.

A network device, comprising:

• a non-transitory memory;
• a processor;
• a transmitter;
• and
• a receiver;
• wherein the non-transitory memory stores a program for execution by the processor, the program including instructions for:
• grouping a first plurality of component carriers configured for a terminal into at least one component carrier group of a first type, wherein control information corresponding to a first component carrier is sent to the terminal over a second component carrier, wherein the first component carrier and the second component carrier belong to a same component carrier group of the at least one component carrier group of the first type, and when a second plurality of component carriers in at least two component carrier groups of the at least one component carrier group of the first type are scheduled, the terminal aggregates feedback information corresponding to the second plurality of component carriers and feeds back the aggregated feedback information to the network device over one component carrier;
• and
• grouping a third plurality of component carriers configured for the terminal into at least one component carrier group of a second type, wherein the terminal sends feedback information corresponding to each component carrier in the at least one component carrier group of the second type to the network device over a primary component carrier or one component carrier in the at least one component carrier group of the second type, and wherein there is an intersection set between each component carrier group of the at least one component carrier group of the first type and the at least one component carrier group of the second type;
• and
• wherein the transmitter is configured to:
• send first grouping configuration information to the terminal, wherein the first grouping configuration information indicates a grouping result of the at least one component carrier group of the first type;
• and
• send second grouping configuration information to the terminal, wherein the second grouping configuration information indicates a grouping result of the at least one component carrier group of the second type.

A terminal, comprising:

• a non-transitory memory;
• a processor;
• and
• a transceiver;
• wherein the non-transitory memory stores a program for execution by the processor, the program including instructions for:
• receiving, using the transceiver, first grouping configuration information sent by a network device, wherein the first grouping configuration information indicates a grouping result of at least one component carrier group of a first type;
• receiving, using the transceiver, control information corresponding to a first component carrier that is sent by the network device over a second component carrier, wherein the first component carrier and the second component carrier belong to a same component carrier group of the at least one component carrier group of the first type;
• when a second plurality of component carriers in at least two component carrier groups of the at least one component carrier group of the first type are scheduled, aggregate feedback information corresponding to the second plurality of component carriers, and feed back the aggregated feedback information to the network device over one component carrier using the transceiver;
• receive, using the transceiver, second grouping configuration information sent by the network device, wherein the second grouping configuration information indicates a grouping result of at least one component carrier group of a second type, and wherein there is an intersection set between each component carrier group of the at least one component carrier group of the first type and the at least one component carrier group of the second type;
• and
• send, using the transceiver, feedback information corresponding to each component carrier in each component carrier group of the at least one component carrier group of the second type to the network device over a primary component carrier or one component carrier in the component carrier group of the second type.
