In order to facilitate understanding of the embodiments of the present application, the following technical points are first introduced below:

1. About Non-Terrestrial Networks (NTN)

Non-terrestrial network refers to the use of satellite or unmanned aerial systems (Unmanned Aircraft System,

The network or network segment that the UAS) platform transmits. Typical scenarios that are applicable include the situation where ground base stations cannot be built and ground base stations are damaged, such as continuous coverage in remote mountainous areas, deserts, oceans, and forests, or natural disasters and ground base stations are damaged. emergency communications.

Among them, satellites include Low Earth Orbiting (LEO) satellites, Medium Earth Orbiting (MEO) satellites, Geostationary Earth Orbiting (GEO) satellites and Highly Elliptical Orbiting (HEO) satellites .

A typical scenario of a non-terrestrial network is a transparent forwarding type, that is, a satellite acts as a forwarding relay, as shown in Figure 1.

2. About downlink data reception

The network side sends scheduling signaling (such as Downlink Control Information (DCI)) on the Physical Downlink Control Channel (PDCCH), and the terminal receives it on the Physical Downlink Shared Channel (PDSCH) Data, the time-frequency resources required to receive data on PDSCH are indicated by DCI. In the existing mechanism, after receiving the scheduling signaling, the terminal must attempt to receive data on the PDSCH under normal circumstances (for example, the terminal does not have a working bandwidth part (Bandwidth Part, BWP) handover). When the data is received, it will try to decode the received data, and need to send a Hybrid automatic repeat request (HARQ) feedback. After successful reception, the network side will not continue to schedule the terminal to receive the same data subsequently. If the decoding is unsuccessful, a negative acknowledgement (Negative Acknowledgement, NACK) is fed back to indicate that the network side has not received the data successfully, and the network side can subsequently reschedule the terminal to receive the same data.

The following describes in detail a transmission method, apparatus, device, and readable storage medium provided by the embodiments of the present application through some embodiments and application scenarios thereof with reference to the accompanying drawings.
