Title:
UPLINK SCHEDULING METHOD AND DEVICE, NETWORK DEVICE AND READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/238586
Kind Code:
A1
Abstract:
The embodiments of the present application disclose an uplink scheduling method and device, a network device and a readable storage medium, which are mainly applied to a NB-IoT network. The method provided in the present application comprises: a network device receiving and demodulating a first signal in a first uplink resource allocated to a terminal device, and if an obtained first demodulation result is wrong, determining, according to the first demodulation result, whether the first uplink resource carries uplink data; and if so, sending, at a first coverage level, first retransmission control information to the terminal device; and if not, sending, at a second coverage level, first retransmission control information to the terminal device. Since a coverage level corresponding to the determination result can reflect a coverage level selected when a terminal device monitors downlink data, it is beneficial for a network device to send first retransmission control information at the coverage level selected by the terminal device, thereby being beneficial for the terminal device to receive uplink data and retransmit same according to the first retransmission control information, and improving the message sending success rate of the uplink data.
