Description

A channel transmission method and device thereof

technical field

The present invention relates to the technical field of communication, and in particular, to the technical field of channel transmission.

Background technique

In NTN (Non Terrestrial Network, non-terrestrial communication network equipment) technology, satellite communication is generally used to provide communication services to terrestrial users. Compared with terrestrial cellular network communication, satellite communication has many unique advantages, such as: it is not limited by the user's geographical area, the communication distance is long, and the stability is high.

However, in the NTN system, due to the long communication distance between the terminal device and the satellite (or network device), the RTT (Round Trip Time, round-trip transmission time) of signal transmission is large. For example, in a GEO (Geostationary Earth Orbit, geosynchronous orbit) system, the RTT of signal transmission may be in the order of 100 milliseconds, for example, the RTT of signal transmission may be about 600 ms at most. In an LEO (Low-Earth Orbit, Low Earth Orbit) system, the RTT of signal transmission can be in the order of tens of milliseconds. That is, the RTT of the NTN system is much larger than the RTT of the terrestrial communication system.

Therefore, when the NR HARQ mechanism applied to the terrestrial communication system is applied to the NTN system, it needs to be enhanced. This enhancement includes disabling the HARQ process. The network device may configure disabling for one or some downlink HARQ processes of the terminal device. For a downlink HARQ process that is configured to be disabled, the network device can reuse the HARQ process for data transmission without receiving the HARQ-ACK information corresponding to the TB transmitted in the HARQ process. The network device may also configure disabling for one or some uplink HARQ processes of the terminal device. For an uplink HARQ process that is configured to be disabled, the network device can reuse the HARQ process to transmit other PUSCHs without receiving the PUSCH transmitted by the terminal device through the HARQ process. The physical channel transmission scheduled by reusing the HARQ process may be a new transmission or a retransmission. If the physical channel transmission scheduled by reusing the HARQ process is retransmission, it can be considered as channel blind retransmission.

However, in the process of channel blind retransmission, the problem of inconsistent understanding of data transmission between the terminal device and the network device occurs.

SUMMARY OF THE INVENTION

The present invention provides a channel blind retransmission method, the terminal device and the network device thereof, which can make the terminal device and the network device have a consistent understanding of data transmission.

A channel transmission apparatus, comprising: a receiving unit configured to receive first downlink control information DCI, wherein the first DCI schedules a first hybrid automatic repeat request (HARQ) process to transmit a first physical channel carrying a first transport block TB , the first DCI corresponds to the first information; the confirmation unit is configured to determine the first information according to the first information when the first new data in the first DCI indicates that the NDI information is the same as the second NDI information Whether the TB is the same as the second TB; wherein, the second NDI is the NDI in the second DCI, and the second DCI is the last time received by the receiving unit for scheduling the first HARQ process transmission bearer; the DCI of the second physical channel of the second TB.

A channel transmission device, comprising: a processor and a memory; the processor invokes a program in the memory to execute any one of the above channel transmission methods.

A chip includes: a processor for calling and running a computer program from a memory, and a device installed with the chip executes any one of the above channel transmission methods.

A computer-readable storage medium, characterized in that a program for an uplink transmission method is stored on the computer-readable storage medium, and when the program for an uplink transmission method is executed by a processor, any one of the above channel transmissions is implemented method.

A computer program product, wherein the computer program product is stored in a non-transitory computer-readable storage medium, and when the computer program is executed, any one of the above channel transmission methods is implemented.

The beneficial effect of the present invention is that: in the channel transmission process, the first information is introduced to further judge whether the first TB and the second TB are the same, that is, to judge whether it is a retransmission or a new transmission. Therefore, when the HARQ process is disabled, due to the large RTT, only the NDI information is used to determine whether the retransmission or the new transmission is used, resulting in inconsistent understanding between the network device and the terminal device. Thus, the accuracy of channel transmission is improved.

In NTN (Non Terrestrial Network, non-terrestrial communication network equipment) technology, communication satellites are divided into LEO (Low-Earth Orbit, Low Earth Orbit) satellites, MEO (Medium-Earth Orbit, Medium Earth Orbit) satellites according to different orbital heights , GEO (Geostationary Earth Orbit, geosynchronous orbit) satellite, HEO (High Elliptical Orbit, high elliptical orbit) satellite and so on. The main research at this stage is LEO and GEO. Among them, the altitude of LEO satellites ranges from 500km to 1500km, and the corresponding orbital period is about 1.5 hours to 2 hours. The signal propagation delay of single-hop communication between users is generally less than 20ms. The GEO satellite orbits at an altitude of 35,786 km and orbits the earth for a period of 24 hours. The signal propagation delay of single-hop communication between users is generally 250ms. Therefore, the RTT (Round Trip Time, round trip transmission time) of the NTN system is much larger than the RTT of the terrestrial communication system.

In the HARQ (Hybrid Automatic Repeat Request) mechanism of the NR system, a Stop-and-Wait Protocol (Stop-and-Wait Protocol) is used to send data. In the stop-and-wait protocol, after the sender sends a transport block TB (Transport Block, transport block), it stops and waits for confirmation information. In this way, the sender stops and waits for an acknowledgment after each transmission, resulting in low user throughput. Therefore, NR uses multiple parallel HARQ processes. When one HARQ process is waiting for acknowledgment information, the sender can use another HARQ process to continue sending data. These HARQ processes collectively form a HARQ entity, and the HARQ entity combines the stop-and-wait protocol to allow continuous data transmission. HARQ is divided into uplink HARQ and downlink HARQ. Uplink HARQ is for uplink data transmission, and downlink HARQ is for downlink data transmission. The two are independent of each other.

Based on the stipulations of the current NR protocol, the terminal equipment has its own HARQ entity corresponding to each serving cell. Each HARQ entity maintains a set of parallel downlink HARQ processes and a set of parallel uplink HARQ processes. Currently, each uplink and downlink carrier supports a maximum of 16 HARQ processes. The base station may indicate the maximum number of HARQ processes to the terminal equipment through RRC signaling semi-static configuration according to the deployment of network equipment. If the network device does not provide corresponding configuration parameters, the default number of HARQ processes in downlink is 8, and the maximum number of HARQ processes supported by each uplink carrier is always 16.

Figure 2 illustrates the relationship between the number of supported HARQ processes and RTT as an example of downlink transmission. The maximum number of HARQ processes configured on a terminal device is 16, then if the RTT is less than 16ms, the maximum throughput of the terminal device will not be affected. Yes, there can be parallel HARQ processes for data transmission. Of course, if the RTT is much greater than 16ms, then all HARQ processes of the terminal device may be used for data transmission, and no feedback from the network device is obtained, resulting in the situation that the terminal device has services to be transmitted but no HARQ process can be used. , which will affect the throughput of data transmission on the terminal device side.

However, as mentioned above, in the NTN system, due to the long communication distance between the terminal equipment and the network equipment (ie satellite), the RTT of the signal transmission is very large, which is much larger than the RTT of the terrestrial communication system. Therefore, in the above-mentioned NR system The HARQ mechanism is not applicable to NTN system. Therefore, the HARQ mechanism of the above-mentioned NR system is enhanced. Wherein, the enhancement includes disabling the HARQ process.

The network device may configure disabling for one or some downlink HARQ processes of the terminal device. For a downlink HARQ process that is configured to be disabled, the network device can reuse the HARQ process for data transmission without receiving the HARQ-ACK information corresponding to the TB transmitted in the HARQ process. The network device may also configure disabling for one or some uplink HARQ processes of the terminal device. For an uplink HARQ process that is configured to be disabled, the network device can reuse the HARQ process to transmit other PUSCHs without receiving the PUSCH transmitted by the terminal device through the HARQ process. Thus, the network device can use the disabled downlink/uplink HARQ process to schedule multiple downlink/uplink data packets for the terminal device, thereby increasing the data transmission throughput and reducing the impact of RTT. The physical channel transmission scheduled by the reused HARQ process may be a new transmission or a retransmission. If the physical channel transmission scheduled by reusing the HARQ process is retransmission, it can be considered as channel blind retransmission. Channel blind retransmission is a technique to improve the reliability of data transmission.

Optionally, for downlink transmission or uplink transmission using the HARQ process that is configured to be disabled, transmission methods such as slot aggregation, repeated transmission, and scheduled blind retransmission can be used for the same transmission block to improve data. Transmission reliability.

Referring to FIG. 3 , the following example shows that for HARQ process 7 configured with HARQ-ACK feedback disabled, the network device can use DCI 0, DCI 1 and DCI 2 to schedule the transmission of PDSCH 0, PDSCH 1 and PDSCH 2. When the terminal device receives the flip of the NDI information in the DCI scheduled by the network device for the HARQ process 7, it indicates that the HARQ process 7 is used to transmit new data packets. When the terminal device receives that the NDI information in the DCI scheduled by the network device for the HARQ process 7 is not flipped, it means that the HARQ process 7 is used to transmit the retransmission of the last data packet. However, when the terminal device only receives DCI 0 and DCI 2, but not DCI 1, the terminal device will think that the transport block carried in PDSCH 2 is the same as the transport block carried in PDSCH 0, but in fact, the network device The transmitted transport block carried in PDSCH 2 and the transport block carried in PDSCH 0 are different transport blocks, resulting in inconsistent understanding between the terminal device and the network device.

The following embodiments of the present application will describe in detail how to ensure consistent understanding of data transmission between terminal equipment and network equipment in the NTN system.

There may be C-DAI and/or T-DAI in the DCI scheduling PDSCH; T-DAI may be included in the DCI scheduling PUSCH.

Since C-DAI is used to indicate that the downlink transmission scheduled by the current DCI is the number of downlink transmissions in the HARQ feedback window, when the network device schedules the same TB for multiple downlink transmissions, it can be considered that these multiple downlink transmissions correspond to one downlink transmission , so when scheduling the retransmission of the TB, the C-DAI value may not increase, and accordingly, the terminal device can judge whether the received PDSCH transmission is a retransmission or a new transmission according to this feature.
