Abstract
Embodiments of the present invention disclose a data transmission method, an apparatus, and a communications system. The present invention relates to the communications field, which can improve transmission performance of a carrier and flexibility in using the carrier. The method includes: when a transmitting apparatus sends data, generating control information corresponding to the data; carrying the control information in a primary carrier and send the control information to a receiving apparatus, carrying, according to the control information, the data in at least one carrier of a second type, and sending the data to the receiving apparatus. The present invention is used for data transmission.
Claims20
A data transmission method, comprising:
- generating, by a transmitting apparatus, control information corresponding to data to be sent;
- sending, by the transmitting apparatus, the control information to a receiving apparatus via a primary carrier, wherein the primary carrier belongs to a carrier of a first type;
- and
- sending, by the transmitting apparatus, based on the control information, the data to the receiving apparatus via at least one carrier of a second type.
A data transmission method, comprising:
- receiving, by a receiving apparatus and via a primary carrier, control information from a transmitting apparatus, wherein the primary carrier belongs to a carrier of a first type;
- and
- receiving, by the receiving apparatus according to the control information, data via at least one carrier of a second type.
A transmitting apparatus, comprising:
- a processor, configured to:
- generate control information corresponding to data to be sent, to cause the control information to be carried via a primary carrier, wherein the primary carrier belongs to a carrier of a first type, and to cause, according to the control information, the data to be carried via at least one carrier of a second type;
- and
- a transmitter, configured to send the control information via the primary carrier and the data via the at least one carrier of the second type to the receiving apparatus.
A receiving apparatus, comprising:
- a processor;
- and
- a receiver;
- wherein the processor is configured to control the receiver;
- and
- wherein the receiver is configured to receive, via a primary carrier, control information from a transmitting apparatus, wherein the primary carrier belongs to a carrier of a first type, and to receive, according to the control information, data via at least one carrier of a second type.
