Title:
DATA TRANSMISSION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/050128
Kind Code:
A1
Abstract:
The present application relates to the technical field of short-range wireless communications. Disclosed are a data transmission method and apparatus. In the present application, data is transmitted between a master control device and at least two slave devices in event periods, each event period comprising a first sub-period and a second sub-period; the master control device respectively transmits data to the slave devices in the first sub-period, and receives indication information respectively fed back by the slave devices according to respective data receiving conditions; and according to the indication information of the slave devices in the first sub-period, dynamically configures retransmission time slots for the slave devices in the second sub-period, respectively. In this way, the retransmission time slots corresponding to the slave devices in the second sub-period are consecutive time slots, and the remaining time slots in the second sub-period are also consecutive time slots, thereby facilitating the effective utilization of the remaining time slots and reducing the waste of air interface resources.
