Abstract
Embodiments of the present invention disclose a method, an apparatus, and a system for transmitting data and relate to the communications field. In order to enable more flexible configuration of flexible subframes and increase downlink throughput, a technical solution provided in the present invention is as follows: configuring an HARQ synchronization attribute of a data packet, where the HARQ synchronization attribute includes synchronous HARQ or asynchronous HARQ; configuring an HARQ process ID of the data packet when the HARQ synchronization attribute is configured to asynchronous HARQ; and sending downlink control information for scheduling the data packet to a user equipment.
Claims16
A method for transmitting data, comprising:
- configuring a hybrid automatic repeat request HARQ synchronization attribute of a data packet, wherein the HARQ synchronization attribute comprises synchronous HARQ or asynchronous HARQ, and the data packet is a transport block carried on an uplink shared channel;
- configuring a HARQ process ID of the data packet when the HARQ synchronization attribute of the data packet is configured to be asynchronous HARQ;
- and
- sending downlink control information for scheduling the data packet to a user equipment, wherein the downlink control information indicates the HARQ synchronization attribute and the HARQ process ID,
- wherein the downlink control information includes a bit indicating the HARQ process ID, and wherein the bit also indicates the HARQ synchronization attribute, and
- wherein a first state of the bit indicates the HARQ process ID of the data packet, which indicates that the scheduled data packet uses synchronous HARQ, and a second state of the bit indicates the HARQ process ID of the data packet, which indicates that the schedule data packet uses asynchronous HARQ.
