[0004] However, if the terminal device receives the uplink resource information sent by the base station, the terminal device will return to monitoring the downlink data of the base station at the first coverage level after sending the uplink data. At this time, if the base station demodulates the signal in the uplink resource Failure, the terminal device will not be able to listen to the retransmission control information sent by the base station on the second coverage level, so it will not be able to resend the uplink data, resulting in the failure of the terminal device's uplink data transmission

Embodiment Construction
[0029] Traditional mobile communication networks, such as universal mobile telecommunications system (UMTS) network, global system for mobile communications (GSM) network, LTE network, 5G network, etc., are mainly used to support people-to-people communication. inter-communication business. The terminal device can perform wireless communication in the mobile communication network (or wireless communication network), and the communication can be included in one or more core networks (core network, CN) and radio access network (radioaccess network) included in the communication network. ,RAN) and execute. figure 1 It is a schematic diagram of the structure of the LTE network, refer to figure 1 , the LTE network includes an access node—an evolved node B (evolved node B, eNB), and also includes a core network element, figure 1 Take a mobility management entity (mobility management entity, MME) and a serving gateway (serving gateway, S-GW) as examples. The terminal device is con...

The embodiment of the present application discloses an uplink scheduling method and device, network equipment and a readable storage medium, which are mainly used in NB-IoT networks. The method provided in the present application includes: the network equipment receives and demodulates the first allocated to the terminal equipment For the first signal in an uplink resource, if the obtained first demodulation result is wrong, judge whether the first uplink resource carries uplink data according to the first demodulation result; if so, send the first signal to the terminal device at the first coverage level - retransmission control information; if not, then send the first retransmission control information to the terminal device on the second coverage level. Since the coverage level corresponding to the judgment result can reflect the coverage level selected by the terminal device when monitoring downlink data, it is beneficial for the network device to send the first retransmission control information on the coverage level selected by the terminal device, thereby facilitating the terminal device to receive And the uplink data is resent according to the first retransmission control information, so as to improve the success rate of sending the uplink data.
Description
technical field [0001] The present application relates to the technical field of communications, and in particular to an uplink scheduling method and device, network equipment, and a computer-readable storage medium. Background technique [0002] Traditional mobile communication networks, such as LTE networks, are mainly used to support communication services between people. The future market demand for home device communication and the large-scale deployment of the Internet of Things have put forward new requirements for mobile communication networks, which need to be able to support low-cost (low-cost) machine type communication services (machine type communication, MTC). Unlike conventional terminal devices (such as mobile phones, tablet computers, smart watches, etc.), most low-cost machines (or MTC terminal devices) need to be installed in areas with weak network signals. In order to ensure Low-cost MTC, mobile communication networks need Network coverage enhancement f...
