To ensure that the server always has the latest uplink data available, uplink data is typically sampled at a higher frequency. Therefore, improving the transmission performance of this type of data is a challenge that needs to be addressed.

Core network elements can be implemented by devices, that is, core network elements are core network devices. It is understood that core network devices can also be a type of network equipment.

[0033] The core network elements in the embodiments of the present application may include network elements that process and forward user signaling and data. For example, the core network equipment may include core network access and mobility management function (AMF), session management function (SMF), user plane gateway, location management function (LMF) and other core network equipment. Among them, the user plane gateway may be a server with functions such as mobility management, routing, and forwarding of user plane data, generally located on the network side, such as a serving gateway (SGW) or a packet data network gateway (PGW) or a user plane network element function entity (UPF). Of course, the core network may also include other network elements, which are not listed here one by one.

The embodiments of this application do not limit the scenarios in which the network equipment and terminal devices are located.

[0036] It should be understood that all or part of the functions of the communication device in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (such as a cloud platform).

[0037] Cellular wireless networks require both uplink and downlink transmission for certain types of data, such as XR service data, especially interactive service data. For example, uplink transmission involves user actions, while downlink transmission involves video, audio, and other data generated by the XR application server. In related technologies, uplink transmission of user actions primarily includes user location, altitude, movement speed, and controller movements. With technological advancements, XR services are also introducing tactile-based services, such as those used for precision operations like remote surgery.

[0038] For users, if the total latency of uplink and downlink transmission is less than tens of milliseconds, they can achieve a perfect interactive experience. Based on this, the server can generate downlink feedback based on the latest uplink data to improve the user experience.

[0039] To ensure the server always has the latest uplink data available, uplink data is typically sampled at a high frequency. For example, data related to the user's position, height, movement speed, and joystick movements are sampled and updated at a frequency of tens of milliseconds. Because tactile data involves the delicate perception of the human body, its sampling frequency is much higher than that of ordinary joystick movements, reaching 1,000 times per second.

[0040] Taking tactile data as an example, to ensure that the time from the user sending tactile sample data to receiving the corresponding downlink feedback is short enough, the server usually generates downlink feedback based on the latest uplink tactile data. For example, when generating downlink feedback, the server selects the most recent (i.e., most recently generated) uplink tactile data from the uplink tactile data it has received, and generates downlink feedback based on this tactile data. Therefore, the reason why the client uses high-frequency sampling for tactile data is to ensure that the server always has the latest uplink tactile data available.

[0041] In this case, how to improve the transmission performance of this type of data is a problem that needs to be solved. The following still takes tactile data as an example to introduce the problems that may exist in the transmission process of this type of data.

[0042] Efficient transmission of tactile data

[0043] For wired networks, each tactile sampling data will be transmitted in real time, so the above design (i.e., high-frequency sampling of tactile data) is effective. However, for wireless networks, if all sampled tactile data are transmitted to the server, the cellular wireless network needs to transmit a sampling result in each subframe, which will consume a lot of wireless resources. In order to save wireless resources, the terminal device in the related technology will transmit multiple tactile sampling data to the XR server at one time. However, as mentioned above, after receiving multiple tactile data, the XR server will only generate downlink feedback based on the latest sampling data to ensure user experience. In other words, only part of the multiple tactile data transmitted to XR at one time is valid, and the transmission of other data is actually invalid.

[0044] Figure 2 is an example diagram of uplink and downlink transmission of tactile data. Figure 2 shows the sampling results of tactile data from a single sensor, the uplink transmitted tactile data packet, and the downlink feedback of the tactile data from the network device (such as a video frame).

[0045] Referring to Figure 2, in the sampling results of a tactile signal from a single sensor, some sampled data corresponds to the transmission timing of tactile data, while some sampled data does not. In some embodiments, the transmission timing of tactile data can be determined based on the difference between the tactile data. For example, when the difference between the current tactile data and the previously obtained tactile data is greater than a certain threshold, the current tactile data corresponds to the transmission timing of the tactile data. At the transmission timing of tactile data, the terminal device can transmit multiple tactile data to the network device.

[0046] Continuing with Figure 2, the uplinked tactile data packet may include sampling results from multiple tactile sensors. After receiving the uplinked tactile data, the network device may generate downlink feedback, such as based on the latest tactile data. Taking time T2 as an example, the network device may select the most recent (most recently generated) uplinked tactile data packet A from the uplinked tactile data packets between times T1 and T2, and generate a downlink feedback video frame based on data packet A.

[0047] Retransmission of tactile data

[0048] To ensure data transmission reliability, wireless communication systems incorporate retransmission mechanisms, such as the hybrid automatic repeat-request (HARQ) retransmission mechanism. Based on the HARQ retransmission mechanism, if an uplink tactile data transmission fails, the network device can schedule the terminal device to retransmit. However, as previously mentioned, downlink feedback is always generated based on the latest tactile data. If the network device receives new tactile data before receiving the retransmitted tactile data, the network device will generate downlink feedback based on the new tactile data. In other words, the retransmitted tactile data is no longer valid, or useful to the network device. As shown in Figure 3, the terminal device transmits a piece of tactile data at time T1, but the base station fails to decode it. At time T2, the terminal device is scheduled to retransmit the tactile data. The terminal device retransmits the tactile data at time T1'. However, since the terminal device has already transmitted the updated tactile data at time T3, even if the retransmitted data at time T1' is successful, the tactile data is useless to the server.

[0049] How tactile data is encoded

[0050] Before tactile data is transmitted, it is usually necessary to encode the tactile data. In some embodiments, the terminal device can encode the tactile data in a cumulative manner, which can also be called differential encoding. The differential encoding method is to encode the current data packet according to the difference between the current data packet and the previous data packet. For example, when encoding data packet No. N, it can be encoded based on the data difference between data packet No. N and data packet No. N-1. For example, data packet No. N can indicate that the force to the left is increased by 1 Newton based on data packet No. N-1. In this case, if the network device does not receive the previously sent data packet No. N-1, it will cause the Nth data packet to be misunderstood.

[0051] In order to solve one or more of the above problems, an embodiment of the present application provides a data transmission method, which helps to reduce the uplink load of the network by performing a first processing on a first type of data (i.e., the first data), such as not retransmitting the first data, and / or transmitting part of the first data, thereby helping to improve system performance.

[0052] FIG4 is a flow chart of a data transmission method according to an embodiment of the present application. The method according to an embodiment of the present application will be described below with reference to FIG4 .

[0053] The method shown in Figure 4 may include step S410. In step S410, the terminal device obtains first information.

[0054] The above-mentioned first information can be used to instruct the terminal device to perform a first processing on the first data, wherein the first data can be first type data. The first type data can be business data that "has no meaning to be retransmitted". The business or data mentioned here that "has no meaning to be retransmitted" can be understood as that for this type of business, the retransmitted data is useless to the system, or the system may not use the retransmitted data of this type of business. For example, the first type data can be data with a higher sampling frequency, and the downlink feedback is data generated based on the latest first type data. As an example, the first type data can be tactile data.

[0055] In some embodiments, the first processing may include not retransmitting the first data. As previously described, when a network device receives retransmitted data, it may have already received updated data, making the retransmitted data invalid. Therefore, not retransmitting the first data helps avoid the transmission of invalid data, thereby improving system performance and conserving transmission resources.

[0056] In some embodiments, the first processing may include transmitting part of the first data (which may be referred to as second data), such as transmitting only the second data, or transmitting the second data preferentially. By transmitting part of the first data, the uplink load of the network can be reduced. The second data may, for example, refer to data containing a large amount of information in the first data, data with a higher priority, etc., thereby helping to reduce the uplink load of the network while ensuring user experience. The relevant information of the second data will be introduced later in conjunction with specific examples and will not be repeated here.

[0057] In some embodiments, the first processing includes transmitting part of the first data and not retransmitting the first data. In this case, the first information may jointly indicate the execution of the above two processings on the first data, or may separately indicate whether to execute the above two processings on the first data. For example, the first information may respectively indicate the transmission of part of the first data and not retransmitting the first data through different values ​​of a parameter, or the transmission of all the first data and the retransmission of the first data through two parameters. As another example, the first information may respectively indicate whether to transmit part of the first data and whether to not retransmit the first data through two parameters. As an example, the first information may indicate the transmission of part of the first data through one parameter and indicate the retransmission of the first data through another parameter. As another example, the first information may indicate the transmission of all the first data through one parameter and indicate the not retransmission of the first data through another parameter.

[0058] In some embodiments, whether the terminal device performs the first processing on the first data may be determined based on usage. For example, the terminal device may determine whether to perform the first processing on the first data based on whether uplink resources are sufficient or the uplink load is low. As an example, if uplink resources are sufficient or the uplink load is low, the terminal device may not perform the first processing on the first data. As another example, if uplink resources are insufficient or the uplink load is high, the terminal device may perform the first processing on the first data.

[0059] In some embodiments, the terminal device may determine whether to perform the first processing on the first data based on the protocol predefined information.

[0060] In some embodiments, the terminal device may determine whether to perform the first processing on the first data based on the first information. For example, the terminal device may receive the first information from the network device, or the network device may send the first information to the terminal device. In some embodiments, not performing retransmission on the first data may include multiple situations. For example, HARQ retransmission is not performed on the first data. For another example, HARQ retransmission and radio link control (RLC) retransmission are not performed on the first data. For another example, HARQ retransmission, RLC retransmission, and packet data convergence protocol (PDCP) retransmission are not performed on the first data.

[0061] In some embodiments, the configuration granularity of the first information may be one or more of the following: data service type (e.g., tactile data), data radio bearer (DRB), flow, and packet granularity. For example, the first information may be used to indicate that HARQ retransmission is not performed on tactile data. For another example, the first information may be used to indicate that HARQ retransmission is not performed on DRB X or flow X.

[0062] In order to ensure user experience, the first information can be used to indicate that some tactile data will not be retransmitted. For example, the first information can be used to configure the first data packet not to be retransmitted. In this case, the terminal device can retransmit the second data packet. The first data packet and the second data packet are both data packets of the tactile data group. As an example, the second data packet can be a more important data packet, such as a data packet containing a large amount of information, or a data packet that has a greater impact on user experience. In some embodiments, the terminal device can determine the data packets to be retransmitted and / or the data packets not to be retransmitted, such as the first data packet and / or the second data packet, through application layer notification.

[0063] In some embodiments, the configuration mode of the first information may include explicit configuration and implicit configuration. The configuration mode of the first information is introduced below using HARQ retransmission as an example.

[0064] For example, the first information may be indicated by an enumerated variable. As an example, if the network device configures the DRB characteristic as the enumerated variable "No transmission", the DRB does not require HARQ retransmission; if the network device does not configure this parameter, the DRB requires HARQ retransmission.

[0065] For another example, the first information can be implicitly indicated by a Boolean variable. The value of the Boolean variable can be true ("1") or false ("0"). As an example, when the value of the Boolean variable corresponding to the DRB is true, it indicates that the DRB does not require HARQ retransmission; when the value of the Boolean variable corresponding to the DRB is false, it indicates that the DRB requires HARQ retransmission.

[0066] In some embodiments, the terminal device may receive second information sent by the network device, or the network device may send the second information to the terminal device. The second information may be used to indicate that a first resource is used to transmit the first data, where the first resource is an uplink transmission resource allocated by the network device to the terminal device. In other words, the network device may allocate an uplink transmission resource for transmitting the first data to the terminal device, i.e., the network device may allocate an uplink transmission resource for transmitting data that does not undergo HARQ retransmission to the terminal device.

[0067] There are multiple ways to allocate uplink radio resources, such as dynamic allocation and semi-static allocation. For different ways to allocate uplink radio resources, the second information can be carried in different messages, such as downlink control information (DCI) or radio resource control (RRC) messages.

[0068] In some embodiments, the second information may be carried in a message in which the network device allocates the first resource. For example, if the network device allocates the first resource to the terminal device via an RRC message, the network device may notify the terminal device via the RRC message that the first resource is used to transmit the first data; if the network device allocates the first resource to the terminal device via a DCI, the network device may notify the terminal device via the DCI that the first resource is used to transmit the first data.

[0069] Based on the dynamic allocation method, the network device can allocate the first resource to the terminal device through DCI. In this case, the second information can be carried in the DCI. The semi-static allocation method may include a type 1 (type 1) configured grant (CG) method and a type 2 (type 2) semi-persistent scheduling (SPS) method. In the type 1 CG method, the network device can allocate the first resource to the terminal device through an RRC message. In this case, the network device can notify the terminal device through an RRC message that the first resource is used to transmit the first data. In the type 2 SPS method, the network device can allocate the first resource to the terminal device through an RRC message and DCI. In this case, the network device can notify the terminal device through an RRC message or DCI that the first resource is used to transmit the first data.

[0070] In some embodiments, the first resource may be a portion of resources (referred to as second resources) allocated by the network device to the terminal device. Taking the allocation of the second resource via a type 1 CG as an example, the second information may be used to indicate a portion of the second resource, such as a wireless resource (i.e., the first resource) having an odd system frame number (SFN) in the second resource, used for transmitting the first data.

[0071] In some embodiments, the configuration granularity of the second information can be one or more of the data service type (e.g., tactile data) granularity, DRB granularity, flow granularity, and packet granularity. For example, the second information can be used to instruct the terminal device to use the first resource to transmit the first data. For another example, the second information can be used to instruct the terminal device to use the first resource to transmit data of DRB X or flow X. DRB X or flow X is associated with the first data, or in other words, DRB X or flow X carries the first data.

[0072] In some embodiments, if the amount of the first data is less than the transmission capacity of the first resource, the terminal device may add padding bits to the remaining resources of the first resource. In other embodiments, if the amount of the first data is less than the transmission capacity of the first resource, the terminal device may use the remaining resources of the first resource to transmit other data in addition to the first data, thereby helping to avoid resource waste.

[0073] In some embodiments, the terminal device may determine how to use the remaining resources in the first resource based on the configuration information of the network device or the protocol predefined information, thereby facilitating implementation. In other embodiments, the terminal device may select how to use the remaining resources in the first resource according to the situation. For example, when resources are tight, the remaining resources in the first resource may be used to transmit other data; when resources are sufficient, padding bits may be added to the remaining resources in the first resource. For another example, the terminal device may randomly determine how to use the remaining resources in the first resource.

[0074] As mentioned above, when processing tactile data, the wireless network usually packages and transmits multiple tactile data to the network device at the transmission time. However, the downlink feedback of the network device is generated based on the latest tactile data. Therefore, some of the multiple tactile data packaged and transmitted to the network device may be useless to the network device. Based on this, in an embodiment of the present application, the first processing may include transmitting part of the first data (i.e., the second data), thereby helping to avoid transmitting data that is useless to the network device, and further helping to save resources for transmitting this part of the data.

[0075] Since the shorter the time interval between the generation of tactile data and the generation of downlink feedback of the tactile data, the better the user experience, in some embodiments, the second data can be the latest data obtained from the first data, which helps to improve the user experience. The latest data obtained from the first data can be understood as the data in the first data whose sampling time is closest to the current time.

[0076] For example, the second data can be determined based on the generation time of the data packet. The way of determining the second data based on the generation time of the data packet is associated with the way the terminal device generates the data packet. If the data packets are packaged and transmitted in a first-in-first-out manner, that is, the data that enters the cache first is packaged and transmitted first, then the second data may include the data in the N data packets with the latest generation time. As an implementation method, the data packets of the tactile service can be packaged and transmitted in a last-in-first-out manner, that is, the data that enters the cache later is packaged and transmitted first, so that the network device can obtain the latest tactile data in a timely manner. In this case, the second data may include the data in the N data packets with the earliest generation time. Wherein, N is a positive integer greater than or equal to 1.

[0077] As an example, the N data packets may include data packets that have not been transmitted in the first data. As another example, the N data packets may include data packets that have been transmitted and data packets that have not been transmitted in the first data, that is, regardless of whether the N data packets have been transmitted before.

[0078] The aforementioned N can be configured by the network device. For example, the network device can configure the value of N based on network quality. For example, when the network quality is poor, the value of N can be smaller, and when the network quality is good, the value of N can be larger. This helps ensure that the network device can reliably and promptly receive sufficient tactile data. Alternatively, the network device can blindly configure the value of N to facilitate implementation.

[0079] The above N can be configured by the application server to the terminal device application layer through an application layer message. When the terminal device application layer receives the configuration, it can notify the terminal device access layer of N.

[0080] The above N can be determined by the terminal device. For example, the terminal device can determine N based on the size of the uplink transmission resources. As an example, if the uplink transmission resources available to the terminal device can accommodate B data packets, then the value of N can be less than or equal to B, such as B.

[0081] Different tactile data may have different importance. Based on the importance of the tactile data, the priority of tactile service packets may vary, such as higher priority for more important packets. For example, tactile data packets using initial encoding may have a higher priority than those using differential encoding. This is because the loss of initial encoding packets may have a greater impact on the user experience, while the loss of differential encoding packets may have a smaller impact on the user experience.

[0082] Based on this, the second data may be data with a higher priority in the first data. In other words, the priority of the data packet associated with the second data is higher than the priority of the data packets associated with other data in the first data except the second data.

[0083] In some embodiments, the priority of the first data may be determined by the application layer of the terminal device, or the application layer of the terminal device may indicate the second data. For example, since the tactile data is encoded by the application layer of the terminal device, the application layer of the terminal device may determine the second data based on the encoding method of the tactile data, thereby indicating the second data to the access layer of the terminal device.

[0084] As mentioned above, the second data can be determined based on the generation time and priority of the data packets. For example, the second data can include the data packets with higher priority in the first data and the C packets generated the latest in the first data. Where C is a positive integer greater than or equal to 1. As an example, the value of C can be 1. In this way, the downlink feedback of the network device can achieve both reliability and timeliness.

[0085] In some embodiments, if (M-1) consecutive packets in the first data are discarded or fail to transmit, the second data includes the data in the Mth packet. In other words, in this case, the terminal device prioritizes transmission of the Mth packet or increases the priority of the Mth packet. M is a positive integer greater than or equal to 1. The value of M can be configured by the network device or indicated by the application layer of the terminal device.

[0086] Determining the second data by one or more of the above methods helps to ensure the quality of service (QoS) of the haptic service.

[0087] In some embodiments, if the HARQ transmission corresponding to the second data fails, the terminal device may retransmit the second data using the next uplink wireless resource. It should be noted that the retransmission of the second data mentioned here is not the retransmission of a transport block (TB), but the retransmission of a data packet. The terminal device needs to reorganize a new TB, that is, the retransmission of the second data mentioned here is a new HARQ transmission.

[0088] As mentioned above, the terminal device can transmit part of the first data to the network device. The terminal device can then discard or not transmit the data other than the second data in the first data. Alternatively, after a period of time, the terminal device can discard the data other than the second data in the first data. The term "discard" here can be replaced by "delete," "clear," or the like.

[0089] In some embodiments, in response to completing the transmission of the first data, the terminal device clears the cache of the first HARQ process, where the first HARQ process is the HARQ process used to transmit the first data. If the terminal device only transmits part of the first data (such as the second data) and discards or does not transmit other data, then in response to completing the transmission of the second data, the terminal device clears the cache of the first HARQ process, where the first HARQ process may be the HARQ process used to transmit the second data.

[0090] In some embodiments, after the terminal device transmits the first data, if the network device allocates uplink transmission resources (which may be referred to as third resources) to the terminal device and schedules the terminal device to use the first HARQ process to transmit data, the terminal device may consider that the uplink transmission resources allocated this time are used for the initial transmission of data, rather than for HARQ retransmission, or in other words, the terminal device may use the third resource for the initial transmission of data. The first HARQ process is the HARQ process used to transmit the first data. At this time, regardless of the value of the corresponding new data indicator (NDI) in the DCI that allocates the third resource, the terminal device may use the third resource for the initial transmission of data.

[0091] As mentioned earlier, packet N indicates that the force to the left should be increased by 1 Newton based on packet N-1. However, if the network device does not receive packet N-1, packet N will be misinterpreted. To address this issue, when encoding tactile data, the encoding of packet N can be based on previously transmitted packets, such as whether packet N-1 was successfully transmitted. For example, packet N-1 indicates that the force to the left should be increased by 1 Newton; packet N indicates that the force to the left should be increased by 1 Newton based on the existing force (i.e., based on the content indicated in packet N-1). If packet N-1 is transmitted successfully, packet N can indicate that the force to the left should be increased by 1 Newton based on the existing force. In other words, the encoding result of packet N is an increase of 1 Newton, resulting in a total force increase of 2 Newtons. If packet N-1 fails to transmit, packet N needs to indicate that the force to the left should be increased by 2 Newtons based on the existing force (i.e., based on the content indicated in packet N-2). That is to say, the encoding result of the Nth data packet is to increase 2 Newtons, so that the final result can reach a total increase of 2 Newtons.

[0092] As can be seen, the encoding results for packet N are different depending on whether packet N-1 is successfully or unsuccessfully transmitted. In other words, the above method requires determining the encoding method for the current packet based on the transmission results of the tactile data packet. Therefore, embodiments of the present application provide a tactile data transmission feedback mechanism to assist with the above encoding method.

[0093] In some embodiments, the terminal device can determine whether the first data is transmitted successfully based on one or more of the following: first indication information; and whether the first HARQ process is scheduled for use; wherein the first indication information is used to indicate whether the first data is transmitted successfully, and the first HARQ process is the HARQ process used to transmit the first data.

[0094] For example, the terminal device may receive the first indication information sent by the network device, or the network device may send the first indication information to the terminal device. The network device may send the first indication information to the terminal device based on the decoding result of the first data. As an example, the network device may send the first indication information to the terminal device for each uplink transmission of the first data. As another example, to save transmission resources, if the network device correctly decodes the received first data, the first indication information is not sent to the terminal device; if the network device fails to decode the first data, the first indication information is sent to the terminal device.

[0095] Optionally, the first indication information may be carried in a physical layer message or a media access control element (MAC CE).

[0096] For another example, if the first HARQ process is scheduled for initial data transmission within the first time period, the first data transmission is successful; or if the first HARQ process is not scheduled for initial data transmission within the first time period, the first data transmission fails. In other words, if the network device schedules the terminal device to use the first HARQ process for initial data transmission within the first time period, the first data transmission is successful; if the network device does not schedule the terminal device to use the first HARQ process for initial data transmission within the first time period, the first data transmission fails.

[0097] For another example, if the first HARQ process is scheduled for data retransmission within the second time, the first data transmission fails; or if the first HARQ process is not scheduled for data retransmission within the second time, the first data transmission succeeds.

[0098] Among them, whether the first HARQ process is scheduled for retransmission or new transmission can be determined based on the NDI.

[0099] It should be noted that the second time may be the same as the first time or different from the first time, and this application does not limit this.

[0100] It should be noted that the network device here schedules the terminal device to use the first HARQ process to retransmit data, which is only used to notify the terminal device that "the last uplink data decoding failed" and is not used to notify the terminal device to perform HARQ retransmission.

[0101] In some embodiments, the access layer of the terminal device sends third information to the application layer of the terminal device, where the third information indicates whether the first data was successfully transmitted. In this way, the application layer can determine the encoding method for the haptic data packet based on the third information. The third information can be determined based on the first indication information or based on whether the first HARQ process is scheduled for use.

[0102] For example, regardless of whether the first data is successfully transmitted, the access layer of the terminal device sends the third information to the application layer of the terminal device.

[0103] For another example, the access layer of the terminal device may only send a notification of successful transmission of the first data to the application layer of the terminal device. In this case, if the application layer of the terminal device receives the third information, such as receiving the third information within a third time period, the first data transmission is considered successful; if the application layer of the terminal device does not receive the third information, such as not receiving the third information within the third time period, the first data transmission is considered unsuccessful.

[0104] For another example, the access layer of the terminal device may only send a notification of the failure of the first data transmission to the application layer of the terminal device. In this case, if the application layer of the terminal device receives the third information, such as receiving the third information within a third time period, the first data transmission is considered to have failed; if the application layer of the terminal device does not receive the third information, such as not receiving the third information within the third time period, the first data transmission is considered to have succeeded.

[0105] In some embodiments, the third information may be used to indicate whether a portion of the first data (referred to as the third data) was successfully transmitted, i.e., the terminal device may only notify the application layer of whether the third data was successfully transmitted. The third data may be determined by the application layer and notified to the access layer of the terminal device.

[0106] In some embodiments, the third data can be determined based on the importance of the tactile data. The third data can be, for example, a data packet using initial encoding, or a data packet containing a larger amount of information. For example, if data packet No. N-1 indicates that the force to the left is increased by 1 Newton from the existing force, and data packet No. N indicates that the force to the left is increased by 6 Newtons from the existing force, then the amount of information contained in data packet No. N is greater than the amount of information contained in data packet No. N-1.

[0107] The third data may be the same as the second data mentioned above, or may be different from the second data. For example, the third data may be part of the second data.

[0108] In some embodiments, the application layer of the terminal device can determine the encoding method of subsequent data packets based on the third information, thereby facilitating correct encoding of the tactile data.

[0109] In some embodiments, the data packet associated with the first data, i.e., the data packet of the tactile service, may not have a PDCP sequence number (SN) and / or an RLC SN. When the media access control (MAC) is packetized, the terminal device may packetize according to the order in which the first data arrives at the terminal device access layer, i.e., the data that arrives at the terminal device access layer first is placed in front of the TB, and the data that arrives at the terminal device access layer later is placed after the TB. Accordingly, the network device may deliver the received MAC service data units (SDUs) to the next network device node according to the order in which each MAC service data unit (SDU) is received in the TB.

[0110] In some embodiments, the terminal device can count the data transmission status of the haptic service. The statistical results may include, for example, the number of "successfully transmitted packets," "failed transmitted packets," and "directly discarded untransmitted packets," as well as packet identifiers. The terminal device can report these statistical results to the network device through processes such as user experience (quality of experience) to help improve the user experience.

[0111] In some embodiments, when a terminal device's serving cell switches, the terminal device does not retransmit haptic service data packets to the target cell. This is because downlink feedback for haptic services is always generated based on the latest data, and after the cell switch, these data packets may no longer be useful to the network device. In this case, not retransmitting haptic service data packets helps conserve transmission resources.

[0112] The method provided in the embodiment of the present application can avoid meaningless retransmission of tactile data, so that the terminal device can always transmit the latest data. In addition, in the embodiment of the present application, the terminal device only transmits part of the tactile data, which can reduce the uplink load of the network while meeting QoS requirements.
