Title:
DATA SCHEDULING METHOD, APPARATUS, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/155660
Kind Code:
A1
Abstract:
The embodiments of the present application provide a data scheduling method, an apparatus and a system, being able to improve the flexibility of resource allocation when DCI schedules a plurality of TBs. A network device sends, to a terminal device, DCI for scheduling N TBs. After determining that a downlink channel bearing the first M TBs of the N TBs is transmitted on consecutive first downlink time units, the network device transmits, on the first downlink time units, the downlink channel bearing the M TBs to the terminal device. The terminal device receives the downlink channel bearing the M TBs, and after determining that ACK/NACKs corresponding to the M TBs are transmitted on consecutive first uplink time units, transmits, on the first uplink time units, the ACK/NACKs corresponding to the M TBs to the network device. The start time of the first downlink time units is determined according to the end time of the transmission of the DCI and a first time delay. The start time of the first uplink time units is determined according to the end time of the first downlink time units and a second time delay.
