Extended coverage: For areas that cannot be covered by current cellular communication systems or are costly to cover, such as oceans, deserts, remote mountainous areas, etc., satellite communications can be used to solve communication problems.

Emergency communications: In extreme situations such as disasters such as earthquakes, when cellular communications infrastructure is unavailable, satellite communications can be used to quickly establish communications connections.

Provide industry applications: For example, for delay-sensitive services in long-distance transmission, satellite communications can be used to reduce the delay of service transmission.

It is foreseeable that in the future wireless communication system, satellite communication system and terrestrial cellular communication system will gradually realize deep integration, and truly realize the intelligent connection of all things. However, due to the high-speed movement of satellites, it is impossible to effectively realize the reliability of data interaction in satellite communication scenarios.

In some embodiments, due to the large delay of the satellite communication system, HARQ stalling problems may occur for some IOT devices. For example, as shown in FIG1B , a schematic diagram of the HARQ delay problem of an NB-IoT terminal configured with a HARQ process is provided.

Optionally, in order to avoid the problem of HARQ delay in non-terrestrial network (NTN) scenarios and thus reduce system performance, HARQ disabling or HARQ shutdown operations may be introduced. For example, for a certain HARQ process, if HARQ disabling or HARQ shutdown is configured, the terminal does not feedback HARQ information for the downlink (DL) transmission of the HARQ process. Optionally, the HARQ information may include at least one of an Acknowledgement (ACK) and a Non Acknowledgement (NACK).

Optionally, for IoT terminals, HARQ disabling based on semi-static configuration is currently supported, and HARQ disabling in the semi-static configuration is also supported to be overridden by DCI.

Optionally, in the case of supporting HARQ disabled, the base station cannot know the decoding result of the terminal, nor does it know whether the terminal has successfully received the scheduled DCI. In this embodiment, if the NDI is triggered (toggle), the terminal decoding may have problems. For example, as shown in Figure 1C: the terminal receives DCI 1 (NDI = 0 in the DCI 1) to determine the transmission of the physical downlink shared channel (PDSCH) 1, but the terminal does not successfully decode DCI2; therefore, when the terminal receives DCI3, it finds that NDI = 0 and has not changed; therefore, it is believed that the DCI scheduling is a retransmission of PDSCH1, resulting in a decoding error. For another example, as shown in Figure 1D: the terminal does not receive DCI2; therefore, when the terminal receives DCI3 and finds that NDI has changed, it will be considered that this is a new transmission; however, the base station actually transmits a retransmission of PDSCH2, resulting in the terminal being unable to decode successfully.

In some embodiments, in a satellite communication scenario, due to the long signal transmission distance between the transmitter and the receiver, data transmission has a short arrival time. For transmission with uplink and downlink relationship, it is determined that the terminal needs to compensate for the propagation delay based on the configuration of the base station.

For example, as shown in Figure 1E: the uplink transmission (gNB UL) and downlink transmission (gNB DL) of the base station (gNB) are time-aligned, that is, the frames marked with n in gNB UL and gNB DL in Figure 1E are aligned; and referring to Figure 1E, there is a transmission delay (Delay) between gNB UL and UE's downlink transmission (UE DL); the uplink transmission timing advance (TA) of the UE needs to take into account the transmission delay from the UE to the satellite, so that the uplink transmissions of different UEs can reach the gNB within the predetermined time range.

For example, as shown in FIG1F , the uplink transmission and downlink transmission of the gNB are not aligned, that is, the frames marked as n in the gNB UL and gNB DL in FIG1F are not aligned, and there is an offset in the time domain (gNB DL-UL frame timing shift); there is a transmission delay (Delay) between the downlink transmission of the gNB (gNB DL) and the downlink transmission of the UE (UE DL); similarly, the uplink transmission timing advance (TA) of the UE needs to take into account the transmission delay from the terminal to the satellite, so that the uplink transmissions of different UEs can reach the gNB within a predetermined time range. In this embodiment, the timing offset (gNB DL-UL frame timing shift) in the time domain between the uplink transmission and the downlink transmission of the gNB is taken into account when considering the timing advance.

Step S2105: The terminal determines that the RV indicated by the RV information field in the first DCI is a predetermined RV.

Exemplarily, the capability information reported by the terminal indicates that combined reception of downlink data is not supported, and the terminal determines that the RV used for the downlink data is the predetermined RV; then the terminal does not expect to receive an RV other than the predetermined RV indicated in the first DCI. For example, if the predetermined RVs are RV0 and RV3, then the terminal does not expect to receive an RV other than RV0 and RV3 indicated in the first DCI used for scheduling; if the RV indicated by the first DCI used for scheduling is RV2, the terminal abandons decoding of the data packet scheduled by the first DCI. For example, when the predetermined RV is RV0, if the first DCI indicates RV0; since RV0 is usually used for the first transmission, decoding of the newly transmitted data packet can be achieved. For another example, when the predetermined RV is RV0, if the first DCI indicates RV1; since RV1 is usually used for retransmission, decoding of the retransmitted data packet can be achieved.

Optionally, the terminal determines to decode the new transmission data packet based on the first DCI indicating that the scheduled data packet is a new transmission data packet.

Optionally, the terminal determines not to decode the retransmitted data packet based on the first DCI indication that the scheduled data packet is a retransmitted data packet.

In some embodiments, the above method may include the method described in the above information processing system 100 side, terminal side, network device side, etc., which will not be repeated here.

The present disclosure relates to an information processing method, which includes:

In step S6101, the terminal receives configuration information from the base station to determine whether to support HARQ disabling based on RRC signaling (RRC-based) or HARQ disabling based on DCI (DCI-based).

Step S6102: The terminal reports capability indication information, where the capability indication information is used to indicate whether combined reception of downlink data is supported. Step S6102 is optional.

Optionally, the capability indication information is the capability information in the previous embodiment.

Optionally, when the capability information reported by the terminal does not support the combined reception of downlink data, the terminal determines that the redundant version (RV) used for the downlink data is a specific RV, that is, the terminal does not expect the RV version indicated in the DCI for scheduling transmission to be a value other than the specific RV. For example, if the specific RV version is RV0 and RV3, then the terminal does not expect the RV version indicated in the DCI for scheduling transmission to be an RV other than RV0 and RV3. If the RV version indicated in the DCI of the received scheduling instruction is RV2, the terminal will abandon the decoding of the data scheduled this time. Optionally, the DCI for scheduling transmission can be the first DCI in the previous embodiment; the specific RV can be the predetermined RV in the previous embodiment.

Alternatively, when NDI=1, it indicates that the scheduled data packet is a new data packet; and/or, when NDI=0, it indicates that the scheduled data packet is a data packet for retransmission. As shown in Figure 6A: when the terminal does not receive the scheduling instruction DCI2 from the base station, the terminal receives DCI3 sent by the base station; when the NDI value of DCI3 is judged to be 0, the terminal determines that the data packet is a data packet for new transmission, and data decoding can be performed normally. Optionally, DCI2 and DCI3 can both be the first DCI in the previous embodiment.

Optionally, the target information field is the RV information field. When RV=0, it indicates that the scheduled data packet is a new data packet; and/or, when RV is other values, it indicates that the scheduled data packet is a data packet for retransmission. Optionally, RV being other values may refer to: RV being a value other than 0, for example, 1, etc. As shown in Figure 6B: when the terminal does not receive the scheduling instruction DCI2 from the base station, the terminal receives DCI3 sent by the base station; when it is determined that the RV value of DCI3 is 0, although the value of NDI has not changed, the terminal determines that RV is a value representing a new transmission; the terminal determines that the data packet is a data packet for new transmission, and data decoding can be performed normally.
