Description

Technical Field

[0001] The embodiments of the present application relate to the field of communication technologies, and in particular, to a data processing method, apparatus, device, and storage medium. Background Art

[0002] The 5G NR (New Radio) system has a two-level retransmission mechanism: the HARQ (Hybrid Automatic Repeat reQuest) mechanism at the MAC (Media Access Control) layer and the ARQ (Automatic Repeat reQuest) mechanism at the RLC (Radio Link Control) layer. The retransmission of lost or incorrect data is mainly handled by the HARQ mechanism at the MAC layer and supplemented by the retransmission function at the RLC layer.

[0003] In the related art, if a 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 from the network device before sending the 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 will consider the received data as the retransmission data for the second data, and then the terminal device will merge and decode the received data (i.e., the retransmission data of the first data) with the second data in the buffer, which will cause the problem of data contamination.

[0035] To make the objectives, technical solutions, and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail with reference to the accompanying drawings.

[0036] The network architecture and service scenarios described in the embodiments of the present application are for more clearly illustrating the technical solutions of the embodiments of the present application, and do not constitute a limitation to the technical solutions provided by the embodiments of the present application. Those of ordinary skill in the art may know that with the evolution of the network architecture and the emergence of new service scenarios, the technical solutions provided by the embodiments of the present application are equally applicable to similar technical problems.

[0037] Please refer to Figure 1 , which shows a schematic diagram of a network architecture provided by an embodiment of the present application. The network architecture may include: a network device 10 and a terminal device 20.

[0038] The network device 10 is a device for providing wireless communication services for the terminal device 20. A connection may be established between the network device 10 and the terminal device 20, so as to communicate through this connection, including the interaction of signaling and data. The number of network devices 10 may be multiple, and communication may also be performed between two adjacent network devices 10 in a wired or wireless manner. The terminal device 20 may switch between different network devices 10, that is, establish connections with different network devices 10.

[0039] In one example, as Figure 2 shown, taking a 5G NTN (Non-Terrestrial Networks) network as an example, the network device 10 in the NTN network may be a satellite 11. A satellite 11 may cover a certain range of ground areas and provide wireless communication services for the terminal devices 20 on this ground area. In addition, the satellite 11 may orbit around the earth, and by deploying multiple satellites 11, communication coverage of different regions on the earth's surface can be achieved.

[0040] Compared with the terrestrial cellular communication network, satellite communication has many unique advantages. First of all, satellite communication is not restricted by the user's geographical location. For example, general terrestrial communication cannot cover areas such as the ocean, high mountains, and deserts where it is impossible to set up communication equipment or where communication coverage is not provided due to sparse population. For satellite communication, since a single satellite can cover a large area of the ground and the satellite can orbit the Earth, theoretically every corner of the Earth can be covered by satellite communication. Secondly, satellite communication has great social value. Satellite communication can cover remote mountainous areas, poor and underdeveloped countries or regions at a relatively low cost, enabling people in these areas to enjoy advanced voice communication and mobile Internet technologies, which is conducive to narrowing the digital divide with developed regions and promoting the development of these regions. Thirdly, satellite communication has a long communication distance, and the communication cost does not increase significantly as the communication distance increases; finally, satellite communication has high stability and is not restricted by natural disasters.

[0041] Communication satellites are divided into LEO (Low-Earth Orbit) satellites, MEO (Medium-Earth Orbit) satellites, GEO (Geostationary Earth Orbit) satellites, HEO (High Elliptical Orbit) satellites, etc. according to different orbital heights. At the current stage, the main research focuses on LEO and GEO.

[0042] 1. LEO

[0043] The altitude range of low-orbit satellites is 500 km to 1500 km, 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 20 ms. The maximum satellite visibility time is 20 minutes. The signal propagation distance is short, the link loss is small, and the requirement for the transmission power of user terminal equipment is not high.

[0044] 2. GEO

[0045] Geostationary orbit satellites have an orbital altitude of 35786 km and a rotation period around the Earth of 24 hours. The signal propagation delay of single-hop communication between users is generally 250 ms.

[0046] To ensure satellite coverage and improve the system capacity of the entire satellite communication system, satellites use multi-beam to cover the ground. A single satellite can form dozens or even hundreds of beams to cover the ground; a satellite beam can cover a ground area with a diameter of dozens to hundreds of kilometers.

[0047] In another example, such as Figure 3As shown, taking a cellular communication network as an example, the network device 10 in the cellular communication network may be a base station 12. The base station 12 is a device deployed in the access network to provide wireless communication functions for the terminal device 20. The base station 12 may include various forms of macro base stations, micro base stations, relay stations, access points, and so on. In systems adopting different radio access technologies, the names of the devices with base station functions may be different. For example, in the 5G NR system, it is called gNodeB or gNB. With the evolution of communication technologies, the name of the "base station" may change. For the convenience of description, in the embodiments of the present application, the device that provides wireless communication functions for the terminal device 20 is collectively referred to as a base station.

[0048] In addition, the terminal device 20 involved in the embodiments 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, as well as various forms of user equipment (User Equipment, UE), mobile station (Mobile Station, MS), terminal device (terminal device), and so on. For the convenience of description, in the embodiments of the present application, the devices mentioned above are collectively referred to as terminal devices.

[0049] In addition, in the embodiments of the present application, the nouns "network" and "system" are usually used interchangeably, but those skilled in the art can understand their meanings.

[0050] The technical solutions described in the embodiments of the present application can be applied to NTN systems and can also be applied to cellular network systems.

[0051] Next, the HARQ mechanism in the NR system will be introduced and described.

[0052] NR has two levels of retransmission mechanisms: the HARQ mechanism at the MAC layer and the ARQ mechanism at the RLC layer. The retransmission of lost or incorrect data is mainly handled by the HARQ mechanism at the MAC layer and supplemented by the retransmission function of the RLC layer. The HARQ mechanism at the MAC layer can provide fast retransmission, and the ARQ mechanism at the RLC layer can provide reliable data transmission.

[0053] HARQ uses the Stop-and-Wait Protocol to send data. In the Stop-and-Wait Protocol, after the sender sends a TB (Transport Block), it stops and waits for the acknowledgment information. In this way, the sender stops and waits for the acknowledgment after each transmission, which results in a very low user throughput. Therefore, NR uses multiple parallel HARQ processes. When one HARQ process is waiting for the acknowledgment information, the sender can use another HARQ process to continue sending data. These HARQ processes together form a HARQ entity, which combines the Stop-and-Wait Protocol and allows 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.

[0054] Based on the current NR protocol regulations, the terminal has its own 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 a maximum of 16 HARQ processes. The base station can semi-statically configure and indicate the maximum number of HARQ processes to the UE through RRC signaling according to the network deployment situation. If the network does not provide the corresponding configuration parameters, the default number of downlink HARQ processes is 8, and the maximum number of HARQ processes supported by each uplink carrier is always 16. Each HARQ process corresponds to a HARQ process ID. For the downlink, the BCCH (Broadcast Control Channel) uses a dedicated broadcast HARQ process. For the uplink, the Msg3 transmission in the random process uses HARQ ID 0.

[0055] For terminals that do not support downlink spatial multiplexing, each downlink HARQ process can only process 1 TB at the same time; for terminals that support downlink spatial multiplexing, each downlink HARQ process can process 1 or 2 TBs at the same time. Each uplink HARQ process of the terminal processes 1 TB at the same time.

[0056] HARQ is divided into synchronous and asynchronous types in the time domain and non-adaptive and adaptive types in the frequency domain. The asynchronous adaptive HARQ mechanism is used for both uplink and downlink in the NR system. Asynchronous HARQ means that retransmission can occur at any time, and the time interval between the retransmission of the same TB and the previous transmission is not fixed. Adaptive HARQ means that the frequency domain resources and MCS (Modulation and Coding Scheme) used for retransmission can be changed.

[0057] For downlink, if a scheduling retransmission occurs, the UE combines the received data with the data in the soft buffer and then decodes it. For new transmission, the UE decodes the received data without combining.

[0058] In the related art, if the network device schedules a new transmission of the first data for a certain HARQ process (such as HARQ process 1), the terminal device may receive a new transmission scheduling of the second data for the same HARQ process (i.e., HARQ process 1) from the network device before sending the 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 will consider the received data as the retransmission data for the second data, and then the terminal device will combine and decode the received data (i.e., the retransmission data of the first data) with the second data in the buffer, which will cause the problem of data contamination.

[0059] Based on this, the embodiments of the present application provide a data processing method, apparatus, device, and storage medium. In the technical solution provided by the embodiments of the present application, when a certain data is retransmission data and the data is not a retransmission of the most recent transmission data in the same HARQ process, the data is independently received and decoded, thereby avoiding the problem of data contamination caused by erroneously combining and decoding the data with the data in the buffer, and improving the success rate and accuracy of data reception and decoding.

[0060] Next, the technical solution of the present application will be introduced and described in conjunction with several exemplary embodiments.

[0061] Please refer to Figure 4 , which shows a flowchart of a data processing method provided by an embodiment of the present application. This method can be applied to Figures 1 to 3 the network architecture shown, and this method may include the following steps (410 to 420):

[0062] Step 410, the network device sends the first data to the terminal device.

[0063] For downlink transmission, the first data is the downlink data sent by the network device to the terminal device. Optionally, the first data may include one TB or multiple TBs.

[0064] 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; it may also be retransmitted data. That is, in the case where the terminal device fails to receive a certain data through HARQ feedback, the network device may retransmit the data that failed to be transmitted to the terminal device, and the retransmitted data is the retransmitted data. Therefore, the above first data may be retransmitted data or newly transmitted data.

[0065] Correspondingly, the terminal device receives the first data from the network device.

[0066] Step 420, when the first data is retransmitted data and the first data is not a retransmission of the most recent transmitted data in the same HARQ process, the terminal device independently receives and decodes the first data.

[0067] When the terminal device determines that the first data is retransmitted data and the first data is not a retransmission of the most recent transmitted data in the same HARQ process, the terminal device independently receives and decodes the first data.

[0068] Optionally, before or when sending 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 retransmitted data, the HARQ process corresponding to the first data, and in the case where the first data is retransmitted data, which data the first data is a retransmission of.

[0069] For downlink transmission, the first information may be DG (Downlink Grant) scheduling information. The DG scheduling information may be sent through DCI (Downlink Control Information) signaling on the PDCCH (Physical Downlink Control Channel).

[0070] Optionally, the first information (such as DG scheduling information) includes at least one of the following:

[0071] 1. The first parameter, used to indicate whether the first data is retransmitted data;

[0072] 2. The second parameter, used to indicate the HARQ process corresponding to the first data;

[0073] 3. The third parameter, used to indicate the HARQ enabled state of the HARQ process corresponding to the first data;

[0074] 4. The fourth parameter, used to indicate the data for which retransmission is performed in the case where the first data is retransmitted data.

[0075] In an exemplary embodiment, the above first parameter may include an NDI (New Data Indicator). If the NDI corresponding to the first data is a first value (such as 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 (such as 0), the terminal device determines that the first data is retransmitted data.

[0076] In an exemplary embodiment, the above first parameter may include an RV (Redundancy Version) value. If the RV value corresponding to the first data is a first value (such as 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 (such as 2 or 1), the terminal device determines that the first data is retransmitted data.

[0077] In an exemplary embodiment, the above second parameter may include a HARQ process ID for indicating the HARQ process corresponding to the first data.

[0078] In an exemplary embodiment, the above third parameter may include an indicator. If the indicator is a third value (such as 1), it indicates that the HARQ process corresponding to the first data is in the HARQ enabled state, that is, the HARQ feedback function is in the enabled state; if the indicator is a fourth value (such as 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 prohibited state.

[0079] In an exemplary embodiment, the above fourth parameter includes a TB identifier and / or a HARQ buffer identifier for indicating, in the case where the first data is retransmitted data, which data the first data is a retransmission of.

[0080] In an embodiment of the present application, if the terminal device determines, based on the above first information, that the first data is retransmitted data and the first data is not a retransmission of the most recent transmitted data in the same HARQ process, then the terminal device performs independent reception and decoding on the first data. That is, the terminal device does not perform combined decoding of the first data with the data in the buffer, thereby avoiding the problem of data contamination.

[0081] For example, the network device schedules a new transmission of TB1 for HARQ process 1. Before the terminal device sends the HARQ feedback information of TB1 to the network device, the terminal device receives a new transmission schedule of TB2 for the same HARQ process (i.e., HARQ process 1) from the network device. In this case, if the HARQ feedback information of TB1 sent by the terminal device to the network device is NACK (Non-Acknowledge), correspondingly, the terminal device can indicate which HARQ process, which buffer, which TB the NACK information is for, etc. Then the network device schedules a retransmission of TB1, and the DG scheduling information sent by the network device to the terminal device can indicate to the terminal device that the first data to be sent soon (i.e., the retransmission data of TB1) is retransmission data, the HARQ process corresponding to the first data is HARQ process 1, and the first data is for the retransmission of TB1. After receiving the DG scheduling information, the terminal device can 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 TB1) with the data in the buffer (such as TB2), thus avoiding the problem of data contamination.

[0082] Optionally, when the first data is retransmission data and the first data is not a retransmission of the most recent transmission data in the same HARQ process, the terminal device may also perform the following steps: determine the first data as new transmission data; and / or, do not merge and decode the received first data with the data in the buffer. For example, the terminal device does not instruct the physical layer to merge and decode the received first data with the data in the buffer.

[0083] In an exemplary embodiment, the above HARQ process is a HARQ process in the HARQ disabled state. That is, when the first data is retransmission data, the first data is not a retransmission of the most recent transmission data in the same HARQ process, and the HARQ process is configured in the HARQ disabled state, the terminal device independently receives and decodes the first data.

[0084] In some other examples, the above HARQ process is a HARQ process in the HARQ disabled state. That is, when the first data is retransmission data and the first data is not in the case where the HARQ process is configured in the HARQ disabled state (i.e., the HARQ process corresponding to the first data is configured in the HARQ disabled state), the terminal device independently receives and decodes the first data.

[0085] In some other examples, if the first data is new transmission data, the terminal device independently receives and decodes the first data.

[0086] In some other examples, if the first data is retransmitted data and the first data is retransmitted data for the most recent transmission data in the same HARQ process, the terminal device combines and decodes the first data with the data in the buffer.

[0087] In an exemplary embodiment, when the first data is retransmitted data and the first data is retransmitted data for the second data in the same HARQ process, the terminal device combines and decodes the received first data with the second data in the buffer. When the second data exists in the buffer corresponding to the HARQ process, the terminal device can improve the decoding success rate and accuracy of the first data by combining and decoding the above two. That is to say, it is possible to combine and decode the non-most recent transmission data in the same HARQ process, but it is possible to combine and decode other data.

[0088] Optionally, for a HARQ process, it can be configured with multiple buffers for caching different received data; or, for a HARQ process, it is correspondingly configured with one buffer but the buffer can include multiple different partitions for caching different received data. For example, for a HARQ process, it can be configured with 2 buffers, one buffer for caching the most recent transmission data and the other buffer for caching the data of the previous transmission of the most recent one; or, for a HARQ process, it is correspondingly configured with one buffer but the buffer can include 2 different partitions, one partition for caching the most recent transmission data and the other partition for caching the data of the previous transmission of the most recent one.

[0089] For example, the terminal device first receives TB1 from the network device and caches the TB1 in the first buffer corresponding to HARQ process 1. After that, the terminal device receives TB2 from the network device and caches the TB2 in the second buffer corresponding to HARQ process 1. Then, the terminal device receives the first data from the network device. Assuming that the first data is retransmitted data for TB1, the terminal device combines and decodes the first data with the data in the first buffer.

[0090] In the related art, usually only one buffer is set for the same HARQ process, and the most recently received data will overwrite the data in the buffer. By the above method, even when the retransmitted data is not the most recent transmission data in the same HARQ process, the corresponding data can be obtained for combined decoding, thereby improving the decoding success rate and accuracy of the data.

[0091] In summary, for the technical solution provided in the embodiments of the present application, when a piece of data is retransmitted data and is not a retransmission of the most recent transmission data in the same HARQ process, the data is independently received and decoded, thereby avoiding the problem of data contamination caused by erroneously merging and decoding the data with the data in the buffer, and improving the success rate and accuracy of data reception and decoding.

[0092] In addition, before sending the data, by providing some information to the receiving end, such as indicating whether the data is retransmitted data, the HARQ process corresponding to the data, and in the case where the data is retransmitted data, which data the data is a retransmission of, etc., so that the receiving end can determine the correct receiving and decoding method for the data accordingly.

[0093] Please refer to Figure 5 , which shows a flowchart of a data processing method provided in another embodiment of the present application. This method can be applied to Figures 1 to 3 the network architecture shown, and this method may include the following steps (510 to 590):

[0094] Step 510, the network device sends HARQ configuration information to the terminal device.

[0095] The HARQ configuration information is used to configure parameters related to HARQ. Optionally, the HARQ configuration information may be sent through RRC (Radio Resource Control) signaling. Optionally, the HARQ configuration information includes at least one of the following: the number of HARQ processes, the HARQ enable status 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 enable status of each downlink HARQ process. For example, a certain downlink HARQ process is configured as the HARQ enable status (which means the HARQ feedback function is enabled), or a certain downlink HARQ process is configured as the HARQ disable status (which means the HARQ feedback function is prohibited).

[0096] Correspondingly, the terminal device receives the HARQ configuration information from the network device.

[0097] Step 520, the terminal device sends capability indication information to the network device.

[0098] The capability indication information is used to indicate to the network device the capabilities of the terminal device. Optionally, the capability indication information includes at least one of the following: whether HARQ de - enabling status is supported, whether each HARQ process supports multiple HARQ buffers or transport blocks (TBs). In an exemplary embodiment, the capability indication information includes first sub - information and second sub - information, where the first sub - information is used to indicate whether HARQ de - enabling status is supported, and the second sub - information is used to indicate whether each HARQ process supports multiple HARQ buffers or TBs. Additionally, the second sub - information can be indicated separately for each HARQ process or indicated uniformly for all HARQ processes, and the embodiments of the present application do not make any limitations in this regard.

[0099] Accordingly, the network device receives the capability indication information from the terminal device. It should be noted that in the embodiments of the present application, no limitation is made on the execution sequence of steps 510 and 520. Step 510 can be executed before step 520, can be executed after step 520, or can be executed simultaneously with step 520.

[0100] Step 530, the network device sends first indication information to the terminal device.

[0101] In one example, the first indication information is used to indicate whether to perform HARQ feedback for the HARQ processes in the HARQ de - enabling status. Optionally, the first indication information can be a unified indication for all HARQ processes in the HARQ de - enabling status, for example, indicating that all HARQ processes in the HARQ de - enabling status perform HARQ feedback, or all do not perform HARQ feedback. The first indication information can also be a separate indication for each HARQ process in the HARQ de - enabling status, for example, indicating that one or some of the HARQ processes in the HARQ de - enabling status perform HARQ feedback, and / or indicating that one or some of the HARQ processes in the HARQ de - enabling status do not perform HARQ feedback.

[0102] In another example, the first indication information is used to indicate whether to perform HARQ feedback for a certain HARQ process. For example, the first indication information can indicate whether corresponding HARQ feedback is required for a certain or some specific HARQ processes.

[0103] Accordingly, the terminal device receives the first indication information from the network device.

[0104] It should be noted that when the terminal device sends the capability indication information to the network device, the network device may determine the first indication information sent to the terminal device based on the capability indication information. 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. The embodiments of the present application do not limit this.

[0105] Step 540, the network device sends the first information related to the first data to the terminal device.

[0106] Before or when the network device sends the first data to the terminal device, the network device may send the first information related to the first data to the terminal device, such as the DG scheduling information or DCI information of the first data.

[0107] Optionally, the first information includes at least one of the following:

[0108] The first parameter, which is used to indicate whether the first data is retransmitted data;

[0109] The second parameter, which is used to indicate the HARQ process corresponding to the first data;

[0110] The third parameter, which is used to indicate the HARQ enabling state of the HARQ process corresponding to the first data;

[0111] The fourth parameter, which is used to indicate the data targeted by the retransmission in the case that the first data is retransmitted data.

[0112] Correspondingly, the terminal device receives the first information from the network device.

[0113] For the introduction and description of the first information, reference can be made to the above Figure 4 embodiment, and this embodiment will not be elaborated herein.

[0114] Step 550, the network device sends the first data to the terminal device.

[0115] Correspondingly, the terminal device receives the first data from the network device.

[0116] It should be noted that the above first information related to the first data may be sent simultaneously with the first data, or may be sent before the first data. If the first information related to the first data and the first data are sent simultaneously, then the above steps 540 and 550 are the same step.

[0117] Step 560, in the case that the first data is retransmitted data and the first data is not a retransmission of the most recent transmission data in the same HARQ process, the terminal device independently receives and decodes the first data.

[0118] Optionally, the HARQ process is a HARQ process in the HARQ disabled state.

[0119] For the introduction and description of the above steps 550-560, please refer to the above text. Figure 4 In the embodiments, this embodiment will not be elaborated herein.

[0120] Step 570: After the terminal device receives the first data, it determines whether to perform HARQ feedback for the first data.

[0121] In one example, the terminal device determines whether to perform HARQ feedback for the first data based on the above first indication information. For example, if the first indication information indicates performing HARQ feedback for a HARQ process in the HARQ disabled state, then if the HARQ process corresponding to the first data is in the HARQ disabled state, the terminal device determines to perform HARQ feedback for the first data. If the first indication information indicates not performing HARQ feedback for a HARQ process in the HARQ disabled state, then if the HARQ process corresponding to the first data is in the HARQ disabled state, the terminal device determines not to perform HARQ feedback for the first data.

[0122] In another example, the terminal device determines whether to perform HARQ feedback for the first data based on the above first indication information. For example, if the first indication information indicates performing HARQ feedback for HARQ process A, then the terminal device determines to perform HARQ feedback for the first data of HARQ process A. If the first indication information indicates not performing HARQ feedback for HARQ process A, then the terminal device determines not to perform HARQ feedback for the first data of HARQ process A.

[0123] In another example, if the HARQ process corresponding to the first data is configured to be in the HARQ disabled state, the terminal device determines not to perform HARQ feedback for the first data. Conversely, 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.

[0124] Step 580: If it is determined not to perform HARQ feedback for the first data, the terminal device does not generate HARQ feedback information for the first data.

[0125] For example, if it is determined not to perform HARQ feedback for the first data, the terminal device does not instruct the physical layer to generate HARQ feedback information for the first data.

[0126] Step 590: If it is determined to perform HARQ feedback for the first data, the terminal device generates and sends HARQ feedback information for the first data.

[0127] 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 sends the HARQ feedback information to the network device.

[0128] In addition, the HARQ feedback information for the first data may be ACK (Acknowledge, confirmation information) or NACK, where ACK indicates that the first data is successfully received and does not need to be retransmitted, and NACK indicates that the first data is not successfully received and needs to be retransmitted.

[0129] Optionally, the HARQ feedback information for the first data includes a fifth parameter, which is used to indicate the data targeted by the HARQ feedback information. Optionally, the fifth parameter includes: a TB identifier, and / or, a HARQ buffer identifier. By carrying the above information in the HARQ feedback information, the network device can know which data the HARQ feedback information is targeted at.

[0130] Optionally, when the terminal device fails to decode the first data, it 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 put into the buffer of the first data, so that when the retransmitted data of the first data is received again later, it can be combined with the data in the buffer for combined decoding to improve the success rate and accuracy of data decoding.

[0131] In summary, for the technical solution provided in the embodiments of the present application, when a certain data is retransmitted data and is not a retransmission of the most recent transmission data in the same HARQ process, the data is independently received and decoded, thereby avoiding the problem of data contamination caused by erroneously combining the data with the data in the buffer, and improving the success rate and accuracy of data reception and decoding.

[0132] In the above embodiments, the downlink transmission process is introduced and described. The technical solution provided by the present application is equally applicable to the uplink transmission process.

[0133] Please refer to Figure 6 , which shows a flowchart of a data processing method provided by another embodiment of the present application. This method can be applied to Figures 1 to 3 the network architecture shown, and this method may include the following steps (610-620):

[0134] Step 610: The terminal device sends the first data to the network device.

[0135] For uplink transmission, the first data is the uplink data sent by the terminal device to the network device. Optionally, the first data may include one transport block (TB) or multiple TBs.

[0136] 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; or it may be retransmitted data. That is, in the case where the network device feeds back that the reception of a certain data fails through Hybrid Automatic Repeat reQuest (HARQ), the terminal device may retransmit the data for which the transmission fails to the network device, and the retransmitted data is the retransmitted data. Therefore, the above first data may be retransmitted data or newly transmitted data.

[0137] Correspondingly, the network device receives the first data from the terminal device.

[0138] Step 620: When the first data is retransmitted data and the first data is not a retransmission of the most recent transmission data in the same HARQ process, the network device performs independent reception and decoding on the first data.

[0139] When the network device determines that the first data is retransmitted data and the first data is not a retransmission of the most recent transmission data in the same HARQ process, the network device performs independent reception and decoding on the first data.

[0140] Optionally, before or when sending 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 retransmitted data, the HARQ process corresponding to the first data, and in the case where the first data is retransmitted data, which data the first data is a retransmission of.

[0141] For uplink transmission, the first information may be an uplink control signaling or a Physical Uplink Shared Channel (PUSCH). Optionally, the first information includes at least one of the following:

[0142] 1. The first parameter, used to indicate whether the first data is retransmitted data;

[0143] 2. The second parameter, used to indicate the HARQ process corresponding to the first data;

[0144] 3. The third parameter, used to indicate the HARQ enabling state of the HARQ process corresponding to the first data;

[0145] 4. The fourth parameter, used to indicate the data for which the retransmission is made in the case where the first data is retransmitted data.

[0146] In an exemplary embodiment, the first parameter may include an NDI. If the NDI corresponding to the first data is a first value (such as 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 (such as 0), the network device determines that the first data is retransmitted data.

[0147] 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 (such as 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 (such as 2 or 1), the network device determines that the first data is retransmitted data.

[0148] In an exemplary embodiment, the second parameter may include a HARQ process ID for indicating the HARQ process corresponding to the first data.

[0149] In an exemplary embodiment, the third parameter may include an indicator. If the indicator is a third value (such as 1), it indicates that the HARQ process corresponding to the first data is in the HARQ enabled state, that is, the HARQ feedback function is in the enabled state; if the indicator is a fourth value (such as 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.

[0150] In an exemplary embodiment, the fourth parameter includes a TB identifier and / or a HARQ buffer identifier for indicating, in the case where the first data is retransmitted data, which data the first data is a retransmission of.

[0151] In an embodiment of the present application, if the network device determines, based on the above first information, that the first data is retransmitted data and the first data is not a retransmission of the most recent transmitted data in the same HARQ process, then the network device performs independent reception and decoding on the first data. That is, the network device does not perform combined decoding of the first data with the data in the buffer, thereby avoiding the problem of data contamination.

[0152] Optionally, in the case where the first data is retransmitted data and the first data is not a retransmission of the most recent transmitted data 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 combined decoding of the received first data with the data in the buffer.

[0153] In an exemplary embodiment, the above HARQ process is a HARQ process in a HARQ disabled state. That is, when the first data is retransmitted data, and the first data is not a retransmission of the most recent transmitted data in the same HARQ process, and the HARQ process is configured in the HARQ disabled state, the network device independently receives and decodes the first data.

[0154] In some other examples, the above HARQ process is a HARQ process in a HARQ disabled state. That is, when the first data is retransmitted data, and the HARQ process is configured in the HARQ disabled state (i.e., the HARQ process corresponding to the first data is configured in the HARQ disabled state), the network device independently receives and decodes the first data.

[0155] In some other examples, if the first data is newly transmitted data, the network device independently receives and decodes the first data.

[0156] In some other examples, if the first data is retransmitted data, and the first data is a retransmission of the most recent transmitted data in the same HARQ process, then the network device combines and decodes the first data with the data in the buffer.

[0157] In an exemplary embodiment, when the first data is retransmitted data, and the first data is a retransmission of the second data in the same HARQ process, the network device combines and decodes the received first data with the second data in the buffer. When the second data exists in the buffer corresponding to the HARQ process, the network device combines and decodes the above two, which helps to improve the decoding success rate and accuracy of the first data. That is to say, it is possible to perform combined decoding on non - most - recent transmitted data in the same HARQ process, but combined decoding can also be performed on other data.

[0158] Optionally, for a HARQ process, multiple buffers can be configured to cache different received data; or, for a HARQ process, one buffer can be correspondingly configured, but the buffer can include multiple different partitions to cache different received data. For example, for a HARQ process, 2 buffers can be configured, one buffer is used to cache the most recent transmitted data, and the other buffer is used to cache the data transmitted in the previous time of the most recent transmission; or, for a HARQ process, one buffer can be correspondingly configured, but the buffer can include 2 different partitions, one partition is used to cache the most recent transmitted data, and the other partition is used to cache the data transmitted in the previous time of the most recent transmission.

[0159] For example, the network device first receives TB1 from the terminal device and caches the TB1 in the first buffer corresponding to HARQ process 1. Then, the network device receives TB2 from the terminal device and caches the TB2 in the second buffer corresponding to HARQ process 1. After that, the network device receives the first data from the terminal device. Assuming that the first data is the retransmission data for TB1, the network device combines and decodes the first data with the data in the first buffer.

[0160] In the related art, usually only one buffer is set for the same HARQ process, and the data in the buffer will be overwritten by the latest received data. Through the above method, even when the retransmission data is not for the most recent transmission data in the same HARQ process, the corresponding data can be obtained for combined decoding, thereby improving the decoding success rate and accuracy of the data.

[0161] In summary, for the uplink transmission using the HARQ mechanism, the technical solution provided by the embodiments of the present application also avoids the problem of data contamination caused by the receiving end wrongly combining and decoding the received data with the data in the buffer, and improves the success rate and accuracy of data reception and decoding.

[0162] In addition, for some other operations or details in the uplink transmission process, reference can be made to the above Figure 4 and Figure 5 the description of the downlink transmission process in the embodiments above, which will not be elaborated here.

[0163] In one example, the downlink transmission process is taken as an example.

[0164] Assume that at time t1, the terminal device receives the DG scheduling information from the network device. Assume that the DG scheduling information is for the new transmission scheduling of data 1, and the HARQ process indicated in the DG scheduling information is HARQ process 1, and HARQ process 1 is in the HARQ disabled state. Then, after receiving the DG scheduling information, the terminal device receives data 1, and since the data 1 is a new transmission, the terminal device can directly perform independent decoding on the data 1.

[0165] Assume that at time t2 (t2 > t1, that is, time t2 is after time t1), the terminal device receives the DG scheduling information from the network device again. Assume that the DG scheduling information is for the new transmission scheduling of data 2, and the HARQ process indicated in the DG scheduling information is HARQ process 1, and HARQ process 1 is in the HARQ disabled state. Then, after receiving the DG scheduling information, the terminal device receives data 2, and since the data 2 is a new transmission, the terminal device can directly perform independent decoding on the data 2.

[0166] Assume that at time t3 (t3 > t2, that is, time t3 is after time t2), the terminal device receives the DG scheduling information from the network device again. Assume that the DG scheduling information is for the retransmission scheduling of Data 1, and the HARQ process indicated in the DG scheduling information is HARQ Process 1, and HARQ Process 1 is in the HARQ disabled state. Then, after receiving the DG scheduling information, the terminal device receives the retransmission data of Data 1. Moreover, since it is the retransmission data of Data 1, rather than the retransmission data of the most recently received data (i.e., Data 2), the terminal device can consider the retransmission data of Data 1 as a new transmission, and the terminal device attempts to decode the retransmission data of Data 1 without instructing the physical layer to perform combined decoding.

[0167] Optionally, if the decoding of the retransmission data of Data 1 is unsuccessful, the terminal device can instruct the physical layer to replace the data in the buffer corresponding to HARQ Process 1 with the data that the MAC layer attempts to decode (in this example, it is the retransmission data of Data 1), so that after receiving the retransmission data of Data 1 again subsequently, it can perform combined decoding with the data in the buffer. In other possible examples, if there is Data 1 stored in the buffer corresponding to HARQ Process 1, then after receiving the retransmission data of Data 1, the terminal device can instruct the physical layer to perform combined decoding on the retransmission data of Data 1 and the Data 1 in the buffer to improve the decoding success rate. For example, if the new transmission data of Data 1 received at time t1 is not cleared or still saved, the terminal device can also perform combined decoding on the data received at time t3 and the data received at time t1.
