Abstract
Embodiments of the present invention relate to the communications field, and provide a method for transmitting data information, a base station, and user equipment, to improve utilization efficiency of a control message. The method includes: determining, by a base station, a carrier for sending data information, determining carrier indication information, and sending a control message corresponding to the data information to user equipment according to the carrier indication information, so that the user equipment receives the data information according to the control message. The method is used to transmit data information.
Claims20
A base station, comprising:
- a processor, configured to determine a carrier for sending data information, determine carrier indication information, and determine, according to the carrier indication information, a control message corresponding to the data information, wherein the carrier comprises two subcarriers, and the carrier indication information indicates that the data information corresponding to the control message is sent on the two subcarriers;
- and
- a communications interface, configured to send the control message determined by the processor to user equipment.
User equipment, comprising:
- a communications interface, configured to:
- receive, from a base station, a control message corresponding to data information transmitted to the user equipment, wherein the data information is transmitted to the user equipment on two subcarriers;
- and
- a processor, configured to acquire carrier indication information according to the control message received by the communications interface, and when the processor determining, according to the carrier indication information, that the data information is carried on the two subcarriers, to perform data processing on the two subcarriers according to the control message, and to acquire the data information, wherein the carrier indication information indicates a subcarrier on which the data information corresponding to the control message is transmitted.
A method for transmitting data information, comprising:
- determining, by a base station, a carrier for sending data information, and determining carrier indication information, wherein the carrier comprises two subcarriers, and the carrier indication information indicates that the data information corresponding to a control message is sent on the two subcarriers;
- and
- sending the control message corresponding to the data information to the user equipment according to the carrier indication information, so that the user equipment receives the data information according to the control message.
A method for transmitting data information, comprising:
- after a base station sends a control message corresponding to data information to user equipment according to carrier indication information, acquiring, by the user equipment, the control message, wherein the data information is transmitted by using two subcarriers;
- acquiring the carrier indication information according to the control message, wherein the carrier indication information indicates a subcarrier on which the data information corresponding to the control message is transmitted;
- and
- performing data processing on the two subcarriers according to the control message, to acquire the data information when it is determined, according to the carrier indication information, that the data information is carried on the two subcarriers.
