It should be noted that the embodiment of the present application does not limit the specific type of the terminal.
In order to facilitate understanding of the embodiments of the present application, the following technical points are introduced below:
one, related to Non-ground network (Non-Terrestrial Networks, NTN)
The non-ground network refers to a network or a network segment which is transmitted by adopting a satellite or Unmanned aerial vehicle (UAS) platform, and is suitable for typical scenes including situations that a ground base station cannot be built and the ground base station is damaged, such as continuous coverage in remote mountainous areas, deserts, oceans and forests, or emergency communication when natural disasters occur and the ground base station is damaged.
The satellites include Low Earth Orbit (LEO) satellites, Medium Earth Orbit (MEO) satellites, Geostationary Earth Orbit (GEO) satellites, and High Elliptic Orbit (HEO) satellites.
A typical scenario for non-terrestrial networks is transparent transponding, i.e. a satellite as a transponded relay, as shown in fig. 1.
Second, regarding downlink data reception
A network side issues scheduling signaling (such as Downlink Control Information (DCI)) on a Physical Downlink Control Channel (PDCCH)), a terminal receives data on a Physical Downlink Shared Channel (PDSCH), and time-frequency resources required for receiving data on the PDSCH are indicated by the DCI. In the existing mechanism, after the terminal receives the scheduling signaling, it must attempt to receive data on the PDSCH under normal conditions (e.g., the terminal does not perform BWP (Bandwidth Part) handover). After receiving the data, the ue tries to decode the received data and needs to send Hybrid automatic repeat request (HARQ) feedback, and if the decoding is successful, an Acknowledgement (ACK) is fed back to indicate that the network side has successfully received the data, and the subsequent network side does not continue to schedule the terminal to receive the same data. If the decoding is unsuccessful, a Negative Acknowledgement (NACK) is fed back to indicate that the network side has not successfully received, and the subsequent network side can reschedule the terminal to receive the same data.
A transmission method, an apparatus, a device, and a readable storage medium provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings and application scenarios thereof.
Referring to fig. 2, an embodiment of the present application provides a transmission method, which is executed by a terminal, and includes the specific steps of: step 201 and step 202.

step 202: receiving new transmission downlink data and/or retransmission downlink data of a first HARQ process scheduled by a network side in a first time;
the network side may be a non-terrestrial network side, such as a network or network segment that employs a satellite or UAS platform for transmission.
It is understood that step 201 and step 202 may be performed sequentially or may be performed simultaneously.
As shown in fig. 3, the first time is initiated after the second time is over; and the second time is started after the data corresponding to the first HARQ process is received, and the terminal does not receive the newly transmitted downlink data and/or the retransmitted downlink data of the first HARQ process scheduled by the network in the second time.
It will be appreciated that. The first time and/or the second time are/is a period of time and can be controlled by a timer, the duration of the timer for controlling the first time is equal to the time length of the first time, and the duration of the timer for controlling the second time is equal to the time length of the second time. The first time and/or the second time may be controlled by different timers. The first time and/or the second time are/is maintained for each HARQ process, and the HARQ process is characterized by disabling HARQ feedback, that is, data transmitted by the network side through the HRAQ process does not need to be fed back, and the terminal does not need to feed back the decoding condition of the data transmitted by the HARQ process to the network side.
In an embodiment of the present application, the starting behavior of the first time and/or the second time may be determined by one or more of the following ways:

(2) network side configuration or pre-configuration;
if the network side configures or pre-configures the first time and starts after the second time is over, the terminal starts the first time after the second time is over; and if the network side is configured or preconfigured for the first time to not start, the terminal does not start the first time.
If the network side configures or pre-configures second time to start after the reception of the newly transmitted data corresponding to the first HARQ process is completed, the terminal starts the second time after the reception of the newly transmitted data corresponding to the first HARQ process is completed; if the network side is configured or preconfigured with the first time and is not started, the terminal does not start the second time;
(3) the terminal is configured or preconfigured.
