Technical Field

The present application relates to the field of communications technologies, and in particular, to a data processing method, apparatus, device, and storage medium.

Background

The 5G NR (New Radio, new air interface) system has a two-level retransmission mechanism: a HARQ (Hybrid Automatic Repeat reQuest) mechanism of a MAC (Media Access Control) layer and an ARQ (Automatic Repeat reQuest) mechanism of an RLC (Radio Link Control) layer. Retransmission of lost or erroneous data is mainly handled by the HARQ mechanism of the MAC layer and is supplemented by the retransmission function of the RLC layer.

In the related art, if the network device schedules a new transmission of first data for a certain HARQ process, the terminal device may receive a new transmission schedule of second data for the same HARQ process by the network device before sending HARQ feedback information of the first data to the network device. In this case, if the network device sends the retransmission data of the first data to the terminal device according to the HARQ feedback information of the first data, the terminal device may consider the received data as retransmission data for the second data, and then the terminal device may merge and decode the received data (i.e., the retransmission data of the first data) with the second data in the buffer, which may cause a problem of data pollution.

Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

The network architecture and the service scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not constitute a limitation to the technical solution provided in the embodiment of the present application, and it can be known by a person skilled in the art that the technical solution provided in the embodiment of the present application is also applicable to similar technical problems along with the evolution of the network architecture and the appearance of a new service scenario.

Referring to fig. 1, a schematic diagram of a network architecture according to an embodiment of the present application is shown. The network architecture may include: network device 10 and terminal device 20.

The network device 10 is a device for providing a wireless communication service to the terminal device 20. A connection may be established between network device 10 and terminal device 20 to communicate, including signaling and data interactions, over the connection. There may be a plurality of network devices 10, and two adjacent network devices 10 may communicate with each other in a wired or wireless manner. The terminal device 20 may switch between different network devices 10, i.e. establish a connection with different network devices 10.

In one example, as shown in fig. 2, a network device 10 in a 5G NTN (Non-Terrestrial Networks) network is a satellite 11. A satellite 11 may cover a range of terrestrial regions to provide wireless communication services to terminal devices 20 in the terrestrial regions. In addition, the satellite 11 can orbit around the earth, and by arranging a plurality of satellites 11, communication coverage of different areas on the earth surface can be realized.

Satellite communications have many unique advantages over terrestrial cellular communication networks. First, satellite communication is not limited by user regions, for example, general terrestrial communication cannot cover regions where communication equipment cannot be set up, such as the sea, mountains, desert, and the like, or communication coverage is not performed due to sparse population, and for satellite communication, since one satellite can cover a large ground and the satellite can orbit around the earth, theoretically every corner on the earth can be covered by satellite communication. Second, satellite communication has great social value. Satellite communication can cover in remote mountain areas, poor and laggard countries or areas with low cost, so that people in the areas can enjoy advanced voice communication and mobile internet technology, the digital gap of developed areas is favorably reduced, and the development of the areas is promoted. Thirdly, the satellite communication distance is long, and the communication cost is not obviously increased when the communication distance is increased; and finally, the satellite communication has high stability and is not limited by natural disasters.

Communication satellites are classified into LEO (Low-Earth Orbit) satellites, MEO (Medium-Earth Orbit) satellites, GEO (Geostationary Earth Orbit) satellites, HEO (High elliptic Orbit) satellites, and the like according to the difference in orbital height. The main studies at the present stage are LEO and GEO.

1、LEO

The height range of the low orbit satellite is 500 km-1500 km, and the corresponding orbit period is about 1.5 hours-2 hours. The signal propagation delay for inter-user single-hop communications is typically less than 20ms. Maximum satellite visibility time 20 minutes. The signal propagation distance is short, the link loss is less, and the requirement on the transmitting power of the user terminal equipment is not high.

2、GEO

A geosynchronous orbit satellite, with an orbital altitude of 35786km, has a period of 24 hours of rotation around the earth. The signal propagation delay for inter-user single-hop communications is typically 250ms.

In order to ensure the coverage of the satellite and improve the system capacity of the whole satellite communication system, the satellite adopts multiple beams to cover the ground, and one satellite can form dozens of or even hundreds of beams to cover the ground; one satellite beam may cover a ground area several tens to hundreds of kilometers in diameter.

In another example, as shown in fig. 3, taking a cellular communication network as an example, the network device 10 in the cellular communication network may be a base station 12. Base station 12 is a device deployed in an access network to provide wireless communication functions for terminal equipment 20. The base stations 12 may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems using different radio access technologies, the names of devices with base station functionality may differ, for example in a 5G NR system, called gnnodeb or gNB. The name "base station" may change as communication technology evolves. For convenience of description, in the embodiment of the present application, the above-mentioned apparatuses providing the terminal device 20 with the wireless communication function are collectively referred to as a base station.

In addition, the terminal device 20 related to the embodiment of the present application may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, and various forms of User Equipment (UE), mobile Stations (MS), terminal devices (terminal device), and so on. For convenience of description, in the embodiments of the present application, the above-mentioned devices are collectively referred to as terminal devices.

In addition, in the embodiments of the present application, the terms "network" and "system" are generally used mixedly, but those skilled in the art can understand the meaning thereof.

The technical solution described in the embodiment of the present application may be applied to an NTN system, and may also be applied to a cellular network system.

Next, an HARQ mechanism in the NR system will be described.

NR has a two-level retransmission mechanism: HARQ mechanism of MAC layer and ARQ mechanism of RLC layer. Retransmission of lost or erroneous data is mainly handled by the HARQ mechanism of the MAC layer and is supplemented by the retransmission function of the RLC layer. The HARQ mechanism of the MAC layer can provide fast retransmission and the ARQ mechanism of the RLC layer can provide reliable data transmission.

HARQ uses a Stop-and-Wait Protocol (Stop-and-Wait Protocol) to transmit data. In the stop-wait protocol, the sender sends a Transport Block (TB), and then stops to wait for an acknowledgement. Thus, the sender may stop after each transmission and wait for an acknowledgement, which may result in low user throughput. Therefore, NR uses a plurality of parallel HARQ processes, and when one HARQ process is waiting for acknowledgement information, the transmitting end can continue to transmit data using another HARQ process. These HARQ processes together constitute a HARQ entity that incorporates a stop-and-wait protocol, allowing for continuous transmission of data. 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 current specification of the NR protocol, the terminal has a respective HARQ entity for 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 16 HARQ processes at maximum. The base station may indicate the maximum number of HARQ processes to the UE through RRC signaling semi-static configuration according to the network deployment situation. If the network does not provide corresponding configuration parameters, the downlink default HARQ process number is 8, and the maximum HARQ process number supported by each uplink carrier is always 16. Each HARQ process corresponds to a HARQ process ID. For downlink, a Broadcast HARQ process is used for the BCCH (Broadcast Control Channel). For uplink, msg3 transmission in the random process uses HARQ ID 0.

For a terminal which does not support downlink space division multiplexing, each downlink HARQ process can only process 1 TB simultaneously; for a terminal supporting downlink space division multiplexing, each downlink HARQ process may process 1 or 2 TBs simultaneously. Each uplink HARQ process of the terminal processes 1 TB simultaneously.

HARQ is classified into two types, synchronous and asynchronous, in the time domain, and non-adaptive and adaptive, in the frequency domain. And in the NR system, the uplink and the downlink use an asynchronous self-adaptive HARQ mechanism. Asynchronous HARQ, i.e. retransmission, can occur at any time, and the time interval between the retransmission of the same TB and the last transmission is not fixed. The adaptive HARQ may change the frequency domain resource and MCS (Modulation and Coding Scheme) used for retransmission.

For downlink, if retransmission is scheduled, the UE combines the received data with the data in the soft buffer, and then decodes the data. For new transmissions, the UE decodes the received data without combining.

In the related art, if the network device schedules a new transmission of first data for a certain HARQ process (e.g., HARQ process 1), the terminal device may receive a new transmission schedule of second data for the same HARQ process (i.e., HARQ process 1) by the network device before sending HARQ feedback information of the first data to the network device. In this case, if the network device sends retransmission data of the first data to the terminal device according to the HARQ feedback information of the first data, the terminal device may consider that the received data is retransmission data for the second data, and the terminal device may merge and decode the received data (i.e., retransmission data of the first data) and the second data in the buffer, which may cause a problem of data pollution.

Based on this, the embodiment of the application provides a data processing method, device, equipment and storage medium. In the technical scheme provided by the embodiment of the application, under the condition that certain data is retransmission data and the data is not retransmission data of the latest transmission data in the same HARQ process, the data is independently received and decoded, so that the problem of data pollution caused by mistakenly combining and decoding the data and the data in the buffer is avoided, and the success rate and the accuracy of data receiving and decoding are improved.

The technical solution of the present application will be described below with reference to several exemplary embodiments.

Referring to fig. 4, a flowchart of a data processing method provided by an embodiment of the present application is shown, where the method is applicable to the network architectures shown in fig. 1 to 3, and the method may include the following steps (410 to 420):

in step 410, the network device sends the first data to the terminal device.

For downlink transmission, the first data is downlink data sent by the network device to the terminal device. Optionally, the first data may include one TB, or may include a plurality of TBs.

In addition, the data sent by the network device to the terminal device may be newly transmitted data, that is, data transmitted for the first time; the network device may also retransmit the data, that is, in a case where the terminal device feeds back a certain data reception failure through the HARQ, the network device may retransmit the data that fails to be transmitted to the terminal device, where the retransmitted data is the retransmission data. Therefore, the first data may be retransmission data or newly transmitted data.

Accordingly, the terminal device receives the first data from the network device.

Step 420, in case that the first data is retransmission data and the first data is not retransmission data of the latest transmission data in the same HARQ process, the terminal device independently receives and decodes the first data.

And the terminal equipment independently receives and decodes the first data under the condition that the first data is determined to be retransmission data and is not retransmission data of the latest transmission data in the same HARQ process.

Optionally, before or while the network device sends the first data to the terminal device, the network device sends first information related to the first data to the terminal device, and the terminal device determines, based on the first information, whether the first data to be sent by the network device is retransmission data, an HARQ process corresponding to the first data, and in a case that the first data is retransmission data, for which data the first data is retransmission data.

For Downlink transmission, the first information may be DG (Downlink Grant) scheduling information. The DG scheduling Information may be transmitted through DCI (Downlink Control Information) signaling on a PDCCH (Physical Downlink Control Channel).

Optionally, the first information (e.g., DG scheduling information) includes at least one of:

1. a first parameter indicating whether the first data is retransmission data;

2. the second parameter is used for indicating the HARQ process corresponding to the first data;

3. a third parameter, configured to indicate an HARQ enabled state of an HARQ process corresponding to the first data;

4. a fourth parameter for indicating data for retransmission if the first data is retransmission data.

In an exemplary embodiment, the first parameter may include NDI (New Data Indicator). If the NDI corresponding to the first data is a first numerical value (e.g., 1), the terminal device determines that the first data is newly transmitted data; if the NDI corresponding to the first data is a second value (e.g., 0), the terminal device determines that the first data is retransmission data.

In an exemplary embodiment, the first parameter may include an RV (Redundancy Version) value. If the RV value corresponding to the first data is a first value (e.g., 0), the terminal device determines that the first data is newly transmitted data; if the RV value corresponding to the first data is a second value (e.g., 2 or 1), the terminal device determines that the first data is retransmission data.

In an exemplary embodiment, the second parameter may include a HARQ process ID for indicating a HARQ process corresponding to the first data.

In an exemplary embodiment, the third parameter may include an indicator, and if the indicator is a third value (e.g. 1), it indicates that the HARQ process corresponding to the first data is in a HARQ enabled state, that is, the HARQ feedback function is in an enabled state; if the indicator is a fourth value (e.g. 0), it indicates that the HARQ process corresponding to the first data is in the HARQ disabled state, that is, the HARQ feedback function is in the disabled state.

In an exemplary embodiment, the fourth parameter includes a TB flag and/or a HARQ buffer flag, which is used to indicate that the first data is retransmission data of which data if the first data is retransmission data.

In this embodiment of the present application, if the terminal device determines that the first data is retransmission data based on the first information, and the first data is not retransmission data of data transmitted last time in the same HARQ process, the terminal device performs independent reception and decoding on the first data. That is, the terminal device does not merge and decode the first data and the data in the buffer, thereby avoiding the problem of data pollution.

For example, the network device schedules a new transmission of TB1 for HARQ process 1, and before the terminal device sends HARQ feedback information of this TB1 to the network device, the terminal device receives a new transmission schedule of TB2 for this same HARQ process (that is, HARQ process 1) by the network device. In this case, if HARQ feedback information for TB1 transmitted to the network device by the terminal device is NACK (Non-acknowledgement information). Accordingly, the terminal device may indicate which HARQ process, which buffer, which TB, etc. the NACK information is for. Then, the network device schedules retransmission of the TB1, and the DG scheduling information sent by the network device to the terminal device may indicate, to the terminal device, that the first data to be sent (that is, retransmission data of the TB 1) is retransmission data, where an HARQ process corresponding to the first data is HARQ process 1, and the first data is for retransmission of the TB 1. After receiving the DG scheduling information, the terminal device may decide to independently receive and decode the first data. That is, the terminal device does not merge and decode the first data (i.e. the retransmission data of TB 1) and the data in the buffer (e.g. TB 2), thereby avoiding the problem of data pollution.

Optionally, in a case that the first data is retransmission data and the first data is not retransmission data of data transmitted last time in the same HARQ process, the terminal device may further perform the following steps: determining the first data as newly transmitted data; and/or, not performing merging decoding on the received first data and the data in the buffer. For example, the terminal device does not instruct the physical layer to perform merge decoding of the received first data with the data in the buffer.

In an exemplary embodiment, the HARQ process is a HARQ process of a HARQ disable state. That is, in the case that the first data is retransmission data, and the first data is not retransmission data for the data transmitted last time in the same HARQ process, and the HARQ process is configured in the HARQ disabled state, the terminal device performs independent reception and decoding on the first data.

In some other examples, the HARQ process described above is a HARQ process of a HARQ disable state. That is, in a case that the first data is retransmission data and the first data is not configured to be in the HARQ disabled state for the HARQ process (that is, the HARQ process corresponding to the first data is configured to be in the HARQ disabled state), the terminal device independently receives and decodes the first data.

In some other examples, the terminal device independently receive decodes the first data if the first data is newly transmitted data.

In some other examples, if the first data is retransmission data and the first data is retransmission data for the most recently transmitted data in the same HARQ process, the terminal device performs merged decoding of the first data and the data in the buffer.

In an exemplary embodiment, in case that the first data is retransmission data and the first data is retransmission data for second data in the same HARQ process, the terminal device performs combined decoding on the received first data and the second data in the buffer. Under the condition that the second data exists in the buffer corresponding to the HARQ process, the terminal equipment combines and decodes the second data and the buffer, and the success rate and the accuracy of decoding the first data are improved. That is, the combining decoding may be performed for the transmission data that is not the latest in the same HARQ process, but may be performed for other data.

Optionally, for one HARQ process, it may configure multiple buffers for buffering different received data; or, for one HARQ process, one buffer is correspondingly configured but the buffer may include a plurality of different partitions for buffering different received data. For example, for one HARQ process, it may configure 2 buffers, where one buffer is used to buffer the data of the latest transmission, and another buffer is used to buffer the data of the latest last transmission; or, for one HARQ process, it configures a buffer but the buffer may include 2 different partitions, where one partition is used to buffer the latest data transmitted last time, and another partition is used to buffer the latest data transmitted last time.

For example, the terminal device receives TB1 from the network device first, and buffers the TB1 in a first buffer corresponding to HARQ process 1, and then receives TB2 from the network device, and buffers the TB2 in a second buffer corresponding to HARQ process 1, and then receives the first data from the network device, and assuming that the first data is retransmission data for TB1, the terminal device combines and decodes the first data and the data in the first buffer.

In the related art, only one buffer is usually arranged for the same HARQ process, and the latest received data can cover the data in the buffer.

To sum up, according to the technical scheme provided by the embodiment of the present application, when a certain data is retransmission data and the data is not retransmission data of the latest transmission data in the same HARQ process, the data is independently received and decoded, so that the problem of data pollution caused by erroneously combining and decoding the data and the data in the buffer is avoided, and the success rate and accuracy of data reception and decoding are improved.

Before transmitting the data, the receiving end is provided with information such as whether the data is retransmission data, a HARQ process corresponding to the data, and in the case where the data is retransmission data, for which data the data is retransmission data, in the scheduling information, so that the receiving end can determine an accurate reception decoding method for the data.

Referring to fig. 5, a flowchart of a data processing method provided by another embodiment of the present application is shown, where the method can be applied to the network architectures shown in fig. 1 to 3, and the method can include the following steps (510 to 590):

step 510, the network device sends HARQ configuration information to the terminal device.

The HARQ configuration information is used to configure HARQ-related parameters. Alternatively, the HARQ configuration information may be sent through RRC (Radio Resource Control) signaling. Optionally, the HARQ configuration information includes at least one of: the number of HARQ processes and the HARQ enabling state correspondingly configured for each HARQ process. For downlink transmission, the number of HARQ processes configured by the network device is the number of downlink HARQ processes. In addition, the network device may also configure the HARQ enabling state of each downlink HARQ process, such as a certain downlink HARQ process is configured as the HARQ enabling state (i.e. indicating that the HARQ feedback function is enabled), and such as a certain downlink HARQ process is configured as the HARQ disabling state (i.e. indicating that the HARQ feedback function is disabled).

Accordingly, the terminal device receives HARQ configuration information from the network device.

In step 520, the terminal device sends capability indication information to the network device.

The capability indication information is used to indicate the capability of the terminal device to the network device. Optionally, the capability indication information comprises at least one of: whether HARQ disable state supports, whether each HARQ process supports multiple HARQ buffers or TBs. In an exemplary embodiment, the capability indication information includes first sub information and second sub information, wherein the first sub information is used to indicate whether a HARQ disable state is supported, and the second sub information is used to indicate whether each HARQ process supports multiple HARQ buffers or TBs. In addition, the second sub information may perform an individual instruction for each HARQ process, or perform a unified instruction for all HARQ processes, which is not limited in this embodiment of the present application.

Accordingly, the network device receives the capability indication information from the terminal device. It should be noted that, in the embodiment of the present application, the execution order of steps 510 and 520 is not limited, and step 510 may be executed before step 520, may be executed after step 520, or may be executed simultaneously with step 520.

Step 530, the network device sends the first indication information to the terminal device.

In one example, the first indication information is used to indicate whether to perform HARQ feedback for a HARQ process of the HARQ disabled state. Optionally, the first indication information may be a unified indication for all HARQ processes of the HARQ disable state, for example, indicating that all HARQ processes of the HARQ disable state perform HARQ feedback, or do not perform HARQ feedback. The first indication information may also be an individual indication for each HARQ process of the HARQ disable state, for example, indicating that the HARQ process of one or some HARQ disable states performs HARQ feedback, and/or indicating that the HARQ process of one or some HARQ disable states does not perform HARQ feedback.

In another example, the first indication information is used to indicate whether HARQ feedback is performed for a certain HARQ process, for example, the first indication information may indicate whether corresponding HARQ feedback is required for a certain HARQ process or certain specific HARQ processes.

Accordingly, the terminal device receives the first indication information from the network device.

It should be noted that, in the case where the terminal device sends the capability indication information to the network device, the network device may determine, based on the capability indication information, the first indication information sent to the terminal device. Of course, in some embodiments, the terminal device may not send the capability indication information to the network device, or the network device may not determine the first indication information sent to the terminal device based on the capability indication information, which is not limited in this embodiment of the present application.

In step 540, the network device sends first information related to the first data to the terminal device.

Before or while the network device transmits the first data to the terminal device, the network device may transmit first information related to the first data, for example, DG scheduling information or DCI information of the first data, to the terminal device.

Optionally, the first information comprises at least one of:

a first parameter indicating whether the first data is retransmission data;

a second parameter, configured to indicate an HARQ process corresponding to the first data;

a third parameter, configured to indicate a HARQ enabled state of a HARQ process corresponding to the first data;

a fourth parameter for indicating data for retransmission if the first data is retransmission data.

Accordingly, the terminal device receives the first information from the network device.

For description of the first information, reference may be made to the embodiment of fig. 4, which is not described again in this embodiment.

In step 550, the network device sends the first data to the terminal device.

The first information related to the first data may be transmitted simultaneously with the first data, or may be transmitted before the first data. If the first information related to the first data and the first data are transmitted simultaneously, the above steps 540 and 550 are the same step.

And step 560, in case that the first data is retransmission data and the first data is not retransmission data of the latest transmission data in the same HARQ process, the terminal device independently receives and decodes the first data.

Optionally, the HARQ process is a HARQ process of a HARQ disable state.

For the description of the above steps 550-560, reference is made to the embodiment of fig. 4, and this embodiment is not repeated herein.

In step 570, the terminal device determines whether to perform HARQ feedback for the first data after receiving the first data.

In one example, the terminal device determines to perform or not to perform HARQ feedback for the first data based on the first indication information. For example, if the first indication information indicates that HARQ feedback is performed for a HARQ process in a HARQ disabled state, the terminal device determines to perform HARQ feedback for the first data if the HARQ process corresponding to the first data is in the HARQ disabled state. If the first indication information indicates that the HARQ process for the HARQ disabling state does not perform HARQ feedback, the terminal device determines not to perform HARQ feedback for the first data if the HARQ process corresponding to the first data is in the HARQ disabling state.

In another example, the terminal device determines to perform or not to perform HARQ feedback for the first data based on the first indication information. For example, if the first indication information indicates HARQ feedback for HARQ process a, the terminal device determines to perform HARQ feedback for the first data of HARQ process a. If the first indication information indicates that no HARQ feedback is performed for the HARQ process A, the terminal device determines not to perform the HARQ feedback of the first data for the HARQ process A.

In another example, the terminal device determines not to perform HARQ feedback for the first data if the HARQ process corresponding to the first data is configured in the HARQ disabled state. On the contrary, if the HARQ process corresponding to the first data is configured to be in the HARQ enabled state, the terminal device determines to perform HARQ feedback for the first data. In this case, the terminal device decides by itself whether to perform HARQ feedback for the first data.

In step 580, if it is determined that the HARQ feedback for the first data is not performed, the terminal device does not generate HARQ feedback information for the first data.

For example, if it is determined that HARQ feedback for the first data is not performed, the terminal device does not instruct the physical layer to generate HARQ feedback information for the first data.

In step 590, if it is determined that the HARQ feedback for the first data is performed, the terminal device generates and transmits HARQ feedback information for the first data.

For example, if it is determined to perform HARQ feedback for the first data, the terminal device instructs the physical layer to generate HARQ feedback information for the first data, and then transmits the HARQ feedback information to the network device.

In addition, the HARQ feedback information of the first data may be ACK (acknowledgement) or NACK, where ACK indicates that the first data is successfully received without retransmission, and NACK indicates that the first data is unsuccessfully received without retransmission.

Optionally, the HARQ feedback information of the first data includes a fifth parameter, where the fifth parameter is used to indicate data for which the HARQ feedback information is intended. Optionally, the fifth parameter comprises: TB identification, and/or HARQ buffer identification. By carrying the information in the HARQ feedback information, the network device can know which data the HARQ feedback information is for.

Optionally, in the case that the decoding of the first data is unsuccessful, the terminal device replaces the data in the buffer corresponding to the first data with the data that the MAC layer attempts to decode. That is, the data that the MAC layer attempts to decode is placed in the buffer of the first data, so that when the retransmission data of the first data is received again later, the data in the buffer can be combined for decoding, and the success rate and accuracy of data decoding are improved.

In the above embodiment, a downlink transmission process is introduced and described, and the technical solution provided in the present application is also applicable to an uplink transmission process.

Referring to fig. 6, which shows a flowchart of a data processing method provided in another embodiment of the present application, the method may be applied to the network architectures shown in fig. 1 to fig. 3, and the method may include the following steps (610 to 620):

step 610, the terminal device sends the first data to the network device.

For uplink transmission, the first data is uplink data sent by the terminal device to the network device. Optionally, the first data may include one TB, or may include a plurality of TBs.

In addition, the data sent by the terminal device to the network device may be newly transmitted data, that is, data transmitted for the first time; the terminal device may also retransmit the data, that is, in a case where the network device feeds back a certain data reception failure through the HARQ, the data that fails to be transmitted may be retransmitted to the network device again, where the retransmitted data is the retransmitted data. Therefore, the first data may be retransmission data or newly transmission data.

Accordingly, the network device receives the first data from the terminal device.

Step 620, the network device independently receives and decodes the first data when the first data is retransmission data and the first data is not retransmission data of the latest transmission data in the same HARQ process.

And the network equipment independently receives and decodes the first data under the condition that the first data is determined to be retransmission data and is not retransmission data of the latest transmission data in the same HARQ process.

Optionally, before or when the terminal device sends the first data to the network device, the terminal device sends first information related to the first data to the network device, and the network device determines, based on the first information, whether the first data to be sent by the terminal device is retransmission data, an HARQ process corresponding to the first data, and in a case that the first data is retransmission data, for which data the first data is retransmission data.

For Uplink transmission, the first information may be Uplink control signaling or PUSCH (Physical Uplink Shared Channel). Optionally, the first information comprises at least one of:

1. a first parameter indicating whether the first data is retransmission data;

2. a second parameter, configured to indicate an HARQ process corresponding to the first data;

In an exemplary embodiment, the first parameter may include an NDI. If the NDI corresponding to the first data is a first value (e.g., 1), the network device determines that the first data is newly transmitted data; if the NDI corresponding to the first data is a second value (e.g., 0), the network device determines that the first data is retransmission data.

In an exemplary embodiment, the first parameter may include an RV value. If the RV value corresponding to the first data is a first value (e.g., 0), the network device determines that the first data is newly transmitted data; if the RV value corresponding to the first data is a second value (e.g., 2 or 1), the network device determines that the first data is retransmission data.

In this embodiment of the present application, if the network device determines, based on the first information, that the first data is retransmission data and the first data is not retransmission data of data transmitted last time in the same HARQ process, the network device performs independent reception and decoding on the first data. That is, the network device does not merge and decode the first data with the data in the buffer, thereby avoiding the problem of data pollution.

Optionally, in a case that the first data is retransmission data and the first data is not retransmission data of data transmitted last time in the same HARQ process, the network device may further perform the following steps: determining the first data as newly transmitted data; and/or, not performing merging decoding on the received first data and the data in the buffer.

In an exemplary embodiment, the HARQ process is a HARQ process of a HARQ disabled state. That is, in the case that the first data is retransmission data, and the first data is not retransmission data for the data transmitted last time in the same HARQ process, and the HARQ process is configured in the HARQ disabled state, the network device performs independent reception and decoding on the first data.

In some other examples, the HARQ process described above is a HARQ process of a HARQ disabled state. That is, in a case that the first data is retransmission data and the first data is not configured in the HARQ disabled state for the HARQ process (that is, the HARQ process corresponding to the first data is configured in the HARQ disabled state), the network device performs independent reception and decoding on the first data.

In some other examples, the network device independently receive decodes the first data if the first data is newly transmitted data.

In some other examples, if the first data is retransmission data and the first data is retransmission data for the most recently transmitted data in the same HARQ process, the network device performs combined decoding of the first data and the data in the buffer.

In an exemplary embodiment, in case that the first data is retransmission data and the first data is retransmission data for second data in the same HARQ process, the network device performs combined decoding on the received first data and the second data in the buffer. Under the condition that the second data exists in the buffer corresponding to the HARQ process, the network equipment combines and decodes the second data and the buffer, and the success rate and the accuracy of decoding the first data are improved. That is, the combining decoding may be performed for the transmission data that is not the latest in the same HARQ process, but may be performed for other data.

Optionally, for one HARQ process, it may configure multiple buffers for buffering different received data; or, for one HARQ process, a buffer is correspondingly configured but the buffer may include a plurality of different partitions, so as to buffer different received data. For example, for one HARQ process, it may configure 2 buffers, where one buffer is used to buffer the data transmitted last time, and the other buffer is used to buffer the data transmitted last time; or, for one HARQ process, a buffer is correspondingly configured but the buffer may include 2 different partitions, where one partition is used to buffer the data transmitted last time, and another partition is used to buffer the data transmitted last time.

For example, the network device receives TB1 from the terminal device first, and buffers the TB1 in the first buffer corresponding to HARQ process 1, and then receives TB2 from the terminal device, and buffers the TB2 in the second buffer corresponding to HARQ process 1, and then receives the first data from the terminal device, and assuming that the first data is retransmission data for TB1, the network device combines and decodes the first data and the data in the first buffer.

In summary, according to the technical scheme provided by the embodiment of the present application, for uplink transmission using an HARQ mechanism, the problem of data pollution caused by erroneously combining and decoding received data and data in a buffer at a receiving end is also avoided, and the success rate and accuracy of data receiving and decoding are improved.

In addition, regarding some other operations or details in the uplink transmission process, reference may be made to the description of the downlink transmission process in the embodiments of fig. 4 and fig. 5 above, and details are not repeated here.

In one example, a downlink transmission process is taken as an example.

It is assumed that at time t1, the terminal device receives DG scheduling information from the network device, and it is assumed that the DG scheduling information is used for newly transmitting data 1, and the HARQ process indicated in the DG scheduling information is HARQ process 1, and HARQ process 1 is in an HARQ disable state. The terminal device receives the data 1 after receiving the DG scheduling information, and since the data 1 is newly transmitted, the terminal device can directly and independently decode the data 1.

It is assumed that at time t2 (t 2 > t1, that is, time t2 is after time t 1), the terminal device receives DG scheduling information from the network device again, and it is assumed that the DG scheduling information is used for newly transmitting data 2, and the HARQ process indicated in the DG scheduling information is HARQ process 1, and HARQ process 1 is in an HARQ disable state. The terminal device receives the data 2 after receiving the DG scheduling information, and since the data 2 is newly transmitted, the terminal device can directly independently decode the data 2.

It is assumed that at time t3 (t 3 > t2, that is, after time t2 at time t 3), the terminal device receives DG scheduling information from the network device again, and it is assumed that the DG scheduling information is used for retransmission scheduling of data 1, and an HARQ process indicated in the DG scheduling information is HARQ process 1, and HARQ process 1 is in an HARQ disabled state. The terminal device receives the retransmission data of data 1 after receiving the DG scheduling information. Moreover, since the retransmission data of the data 1 is targeted, but not the retransmission data of the data (i.e., the data 2) received last time, the terminal device may consider that the retransmission data of the data 1 is newly transmitted, and attempt to decode the retransmission data of the data 1 without instructing the physical layer to perform the merging decoding.

Alternatively, if the retransmission data of the data 1 is not successfully decoded, the terminal device may instruct the physical layer to replace the data in the buffer corresponding to the HARQ process 1 with the data that the MAC layer attempts to decode (i.e. the retransmission data of the data 1 in this example), so that the terminal device can perform merging decoding with the data in the buffer after receiving the retransmission data of the data 1 again. In other possible examples, if data 1 is stored in a buffer corresponding to HARQ process 1, after receiving the retransmission data of data 1, the terminal device may instruct the physical layer to perform combined decoding on the retransmission data of data 1 and data 1 in the buffer, so as to improve a decoding success rate. For example, if the newly transmitted data of data 1 received at time t1 is not emptied or is not stored, the terminal device may merge and decode the data received at time t3 and the data received at time t 1.
