It should be noted that in the embodiment of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0032] The following describes in detail the method for transmitting synchronization status information provided by the embodiments of the present application through some embodiments and their application scenarios in combination with the accompanying drawings.

[0033] Extended Reality (XR) services include a wide range of services, including video conferencing, video games, video calls, and video-assisted remote work. A multimodal XR service is provided based on a combination of multiple data, including sound, touch, vision, kinesthetic sense, pain, pressure, airflow, and temperature. After the data acquisition end of the multimodal XR service collects multiple data, in order for the peer end to realistically present the scene corresponding to the multimodal data based on the provided multimodal data, the multimodal data needs to be synchronously transmitted to the peer end. For uplink multimodal XR services, the terminal side is the acquisition end of the multimodal data. Based on the scheduling of the base station, the terminal transmits the multimodal data to the base station, and then transmits the multimodal data to the peer end through the base station. The peer end constructs and plays the established scene based on the received multimodal data according to a given time rhythm.

[0034] Based on the above, when an application contains data in multiple modalities and these data need to be transmitted from the terminal to the base station (and then sent to the peer end), these multiple modalities must be transmitted synchronously so that the peer end can use this data and deliver the service. If these multiple modalities are not transmitted synchronously over the air interface, the data in different modalities will lose synchronization. This loss of synchronization will be transmitted to the peer end, reducing the peer end's service quality.

[0035] Related technologies do not address the issue of enhancing multimodal data transmission between base stations and terminals when XR services include multimodal data transmission. Related technologies only report excessively delayed data volume and latency information to the base station by logical channel group (LCG). They fail to report synchronization information between data in different modalities, preventing the base station from performing effective scheduling and compensating for synchronization deviations between data in different modalities.

[0036] In order to solve the above technical problems, the embodiment of the present application provides a method for reporting the synchronization status information between the multi-modal data to the base station when the terminal performs uplink multi-modal data transmission, so that the base station can perform uplink scheduling of the multi-modal data in a timely manner, thereby achieving the purpose of synchronous transmission of the multi-modal data on the air interface.

[0037] As shown in FIG2 , an embodiment of the present application provides a method 200 for transmitting synchronization status information. The method can be executed by a terminal. In other words, the method can be executed by software or hardware installed in the terminal. The method includes the following steps.

[0038] S202: The terminal receives synchronization status information reporting configuration.

[0039] Synchronization status information reporting configuration refers to configuration information regarding the terminal sending synchronization status information to the network side device. The synchronization status information is used to indicate the offset of the completion time of sending multimodal data. The multimodality mentioned in each embodiment of the present application may include at least two modes.

[0040] In one embodiment, the synchronization status information configuration includes at least one of the following:

[0041] 1) Identification of at least one of the multiple modalities. For example, if synchronization status information is reported based on a reference modality, the synchronization status information configuration may include the identification of the reference modality and the identification of the target modality. Thus, the synchronization status information can be used to indicate the offset between the completion time of data transmission of the target modality and the data of the reference modality.

[0042] 2) Parameters for triggering the transmission of synchronization status information. This triggering transmission condition parameter may be a transmission time offset threshold, which may be a time threshold used by the terminal to determine whether to trigger the reporting of synchronization status information. For example, the terminal determines that the completion transmission time of the target modality data corresponding to the same XR frame is later than the completion transmission time of the reference modality data by reaching or exceeding the aforementioned transmission time offset threshold, thereby triggering the reporting of synchronization status information. The completion transmission time may be the time when the terminal completes the transmission to the network-side device.

[0043] 3) The transmission period of the synchronization status information is applicable to the embodiment of periodically reporting the synchronization status information.

[0044] 4) Scheduling Request (SR) resources for synchronization status information. In this example, when sending synchronization status information, SR can be sent through the above-mentioned SR resources. In this way, the network side device (such as a base station) can schedule at least one mode of multi-modal data (usually delayed data) based on SR, so as to achieve the purpose of synchronous transmission of multi-modal data on the air interface as soon as possible.

[0045] S204: The terminal sends synchronization status information between multimodal data based on the synchronization status information reporting configuration.

[0046] In one embodiment, the multimodal data belongs to the same XR frame (ie, data required for the same presentation), and the synchronization status information is generated based on the completion transmission time relationship between the multimodal data belonging to the same XR frame.

[0047] In one embodiment, the synchronization status information is used for uplink scheduling of the multi-modal data.

[0048] In one embodiment, after the terminal sends synchronization status information between multimodal data based on the synchronization status information reporting configuration, the method further includes: the terminal receiving an uplink transmission permission or a configuration for adjusting the multimodal data transmission. The configuration for adjusting the multimodal data transmission includes reconfiguring a logical channel priority (LCP) parameter to accelerate the transmission of delayed data.

[0049] The method by which the network-side device performs the uplink scheduling based on the received synchronization status information includes at least one of the following: allocating uplink transmission permission so that the data of the delayed mode can be transmitted as soon as possible; instructing the terminal to discard the data of the delayed mode to avoid the transmission of the modal data that is too delayed and save wireless resources; instructing the terminal to strengthen the transmission of the delayed modal data, including increasing the transmission power, repeating the transmission or activating the Packet Data Convergence Protocol (PDCP) duplication (i.e., PDCP duplication), etc.

[0050] In this embodiment, after receiving synchronization status information from the terminal, the base station sends an uplink transmission permission to the terminal or adjusts the multi-modal data transmission configuration based on the synchronization status information. For example, the base station increases the scheduling resources for delayed data and increases the LCP of the delayed data, thereby accelerating the transmission of the delayed data.

[0051] The method for transmitting synchronization status information provided in the embodiment of the present application is that the terminal sends synchronization status information between multi-modal data based on the synchronization status information reporting configuration, which is beneficial for compensating for the synchronization deviation between data of different modes and is beneficial for the synchronous transmission of multi-modal data on the air interface.

[0052] In one embodiment (referred to as reporting method 1), the synchronization status information sent by the terminal is determined based on the transmission time of the data of the reference modality in the multimodal data. This embodiment reports synchronization status information based on the reference modality. The synchronization status information may include the transmission time offset between the data of the target modality and the data of the reference modality. This embodiment can directly indicate the transmission time offset between the data of the target modality and the data of the reference modality, reducing the calculation complexity of the network-side device.

[0053] In this embodiment, the base station sends a synchronization status information reporting configuration to the terminal, which is used to configure the terminal to report the transmission time offset between the target modality data and the reference modality data. The synchronization status information reporting configuration may include: the identifier of the target modality, the identifier of the reference modality, the transmission time offset threshold, etc.

[0054] In this embodiment, when the terminal determines that the offset between the send time of the target modality data and the send time of the reference modality data reaches or exceeds the send time offset threshold, the terminal triggers reporting of synchronization status information between the target modality data and the reference modality data. The send time can be the start time of sending or the completion time of sending.

[0055] For example, in this embodiment, when the data of the reference modality has been sent at time X and the data of the target modality has not been sent at time (X+△), the terminal determines that it can trigger the reporting of synchronization status information between the data of the target modality and the data of the reference modality, where △ is the sending time offset threshold.

[0056] The synchronization status information in this embodiment may include one or more of the following: an identifier of the reference mode, an identifier of the target mode, a time offset between the data of the target mode and the data of the reference mode, an indication that the time offset reaches or exceeds the sending time offset threshold, an indication of whether the data of the target mode has been sent; and information on the amount of data remaining to be sent of the target mode.

[0057] When the terminal has many modes, if reporting method 1 is used, a reference mode is configured for each target mode, and then the terminal reports the synchronization status information between each target mode and one or more other reference modes according to the configuration. That is, the amount of data of the modality pair will be relatively large. If the synchronization status of all modality pairs is reported in one synchronization status information, a larger synchronization status information body will be generated.

[0058] To reduce the amount of data reported, another reporting method is to include the transmission time information of at least one mode of data in the synchronization status information. After receiving the synchronization status information, the base station calculates the transmission time offset between any two modes of data based on the transmission time information of each mode of data.

[0059] In one embodiment (referred to as reporting method 2), the synchronization status information includes the transmission time information of at least one modality of the multimodal data. This embodiment reports synchronization status information based on transmission time information, which can reduce the amount of synchronization status information reported and reduce the configuration overhead of synchronization status information reporting.

[0060] In this embodiment, the base station sends a synchronization status information reporting configuration to the terminal, which is used to configure the terminal to report the sending time information of data of at least one modality.

[0061] When the terminal determines that the offset between the sending time of the data of the first modality and the sending time of the data of the second modality reaches or exceeds the sending time offset threshold, it triggers the reporting of synchronization status information, and the synchronization status information includes at least the sending time information of the first modality and the sending time information of the second modality.

[0062] In one embodiment, the synchronization status information mentioned in any of the above embodiments may include at least one of the following:

[0063] 1) An identifier of at least one of the multiple modalities.

[0064] 2) A transmission time offset between data of at least two modes in the multi-modality.

[0065] 3) An indication that a transmission time offset of data of at least two of the multimodal modes reaches or exceeds a preset threshold.

[0066] 4) Whether the sending is completed, used to indicate whether the data of the target modality is sent successfully, and the target modality is one or more modalities in the multimodality.

[0067] 5) Information about the amount of data remaining to be sent of the target modality, where the target modality is one or more modalities in the multimodality. In one embodiment, the information about the amount of data remaining to be sent of the target modality also includes buffer status report (BSR) table indication information, and the BSR table indication information is used to indicate: the BSR table used to quantify the amount of data remaining to be sent of the target modality, so that the network side device can determine the amount of data remaining to be sent of the target modality based on the indicated BSR table. This example uses the BSR table indication method to determine the amount of data remaining to be sent of the target modality, which is conducive to improving the quantization accuracy of the data amount.

[0068] 6) Remaining delay budget information of a target mode, where the target mode is one or more modes in the multi-mode.

[0069] 7) Sending time information of at least one modality of the multimodal data.

[0070] In one embodiment, the sending time information may include at least one of the following:

[0071] 1) Air interface time based on the system frame number (SFN), slot number, or symbol (such as OFDM symbol) number. This air interface time can be NR air interface time.

[0072] 2) Absolute time based on the communication system clock, such as the absolute time based on the 5G system clock.

[0073] 3) Time based on satellite timing.

[0074] 4) A time offset relative to the sending time of the synchronization status information.

[0075] 5) A time offset relative to an arrival time of a target data burst, the target data burst comprising the multimodal data.

[0076] 6) A time offset relative to a target completion time of sending, such as the latest time point of completing sending determined according to a protocol data block (PDB). As an example, the target completion time of sending may be the latest time of completing data sending.

[0077] 7) Residual delay budget information of the target mode.

[0078] In one embodiment, the synchronization status information includes indication information, and the indication information is used to indicate the correspondence between the synchronization status information and the data of one or more modes in the multimodality, and the indication information includes at least one of the following: modality identifier, logical channel (Logical CHannel, LCH) identifier, logical channel group (Logical Channel Group, LCG) identifier, data radio bearer (Data Radio Bearer, DRB) identifier, LCH identifier bitmap, LCG identifier bitmap, DRB identifier bitmap.

[0079] This embodiment can make full use of existing information to indicate the correspondence between synchronization status information and data of one or more modalities in the multi-modality, which is beneficial to reducing data reporting overhead.

[0080] For example, in this embodiment, when data of different modalities is mapped to different data streams, the base station may map the different data streams to different LCHs or LCGs. The base station may configure the terminal to report synchronization status information between different data streams based on the LCH or LCG. The base station uses the LCH ID, LCG ID, and DRB ID to configure the terminal to report synchronization status information. For example, the base station configures the triggering conditions for reporting synchronization status information based on the LCH ID, LCG ID, and DRB ID. In the synchronization status information, the terminal uses the LCH ID, LCG ID, or DRB ID, or a bitmap of the LCH ID, LCG ID, or DRB ID to indicate the correspondence between the synchronization status information and the data of the modality.

[0081] In one embodiment, the synchronization status information between the sending multimodal data includes at least one of the following:

[0082] 1) Periodically send synchronization status information between multi-modal data.

[0083] For example, in this embodiment, the base station configures the terminal to perform statistics on the synchronization status information between multi-modal data, and the terminal periodically reports the synchronization status information between the multi-modal data. The terminal can use Radio Resource Control (RRC) signaling or Media Access Control Control Element (MAC CE) to report.

[0084] 2) Upon receiving an inquiry or request, send synchronization status information between multimodal data.

[0085] For example, in this embodiment, the base station configures the terminal to perform statistics on the synchronization status information between multi-modal data. When the terminal receives the inquiry or request from the base station, it reports the synchronization status information between the multi-modal data to the base station. The terminal can use RRC signaling or MAC CE to report.

[0086] 3) When the pre-configured trigger sending conditions are met, the synchronization status information between the multi-modal data is sent.

[0087] In this embodiment, for example, the base station configures the terminal to monitor synchronization status information between multi-modal data and report the synchronization status information to the base station when a pre-configured trigger transmission condition is met. For example, when the terminal determines that the synchronization offset between the two modalities (i.e., the time offset for completing transmission) reaches or exceeds a first time threshold, the synchronization status information reporting is triggered, and the terminal may use an RRC message or MAC CE to report.

[0088] In one embodiment, the preconfigured trigger sending condition includes: in the multimodal data, the offset of the sending time of the first modality data relative to the sending time of the second modality data reaches or exceeds the first time threshold (or called the sending time offset threshold).

[0089] In one embodiment, the method further includes: the terminal triggering the transmission of an SR based on the synchronization state information, wherein the scheduling request is used to request transmission resources for at least one mode of data in the multimodal data. In this way, a network-side device (such as a base station) can schedule at least one mode of data in the multimodal data (typically delayed transmission data) based on the SR, thereby achieving the purpose of synchronous transmission of the multimodal data over the air interface as quickly as possible.

[0090] In one embodiment, the resources for sending the SR include at least one of the following: 1) SR resources corresponding to the mode that triggers the sending of the synchronization status information, which is beneficial for the network side device to determine the mode that triggers the sending of the synchronization status information based on the SR resources; 2) the SR resources that are closest to the triggering moment of the synchronization status information, so as to achieve the purpose of synchronous transmission of multi-modal data on the air interface as soon as possible; 3) available SR resources, which can be any available SR resources, so as to achieve the purpose of synchronous transmission of multi-modal data on the air interface as soon as possible; 4) dedicated SR resources, which are used to send the SR triggered by the synchronization status information. This example improves SR transmission reliability by configuring dedicated SR resources.

[0091] In this embodiment, for example, when synchronization status information is sent based on pre-configured trigger conditions, when the terminal uses MAC CE signaling to report, the terminal can trigger an SR based on the MAC CE of the synchronization status information. The terminal can send a scheduling request using the SR resource corresponding to the mode that triggered the synchronization status information report, or can send a scheduling request using the most recently available SR resource. Optionally, the base station configures a dedicated SR resource for the terminal for use in the SR triggered by the synchronization status information report.

[0092] In one embodiment, after sending the synchronization status information between multimodal data when the preconfigured trigger sending conditions are met, the method also includes: the terminal starts a target timer; wherein, during the operation of the target timer, the terminal does not send the synchronization status information again.

[0093] This embodiment introduces a target timer to prevent the terminal from frequently triggering the reporting of synchronization status information. When a terminal sends synchronization status information, the target timer is started. During the running of the target timer, the synchronization status information cannot be sent again; when the synchronization status information report is triggered and the target timer is not in the running state, the synchronization status information can be sent.

[0094] In one embodiment, the terminal sends synchronization status information between multi-modal data based on the synchronization status information reporting configuration, including: when the trigger sending condition corresponding to at least one mode in the multi-modality is met, the terminal sends synchronization status information between multi-modal data based on the synchronization status information reporting configuration; wherein the synchronization status information includes the synchronization status information of all modalities configured with synchronization status information reporting.

[0095] For example, in this embodiment, when the terminal triggers the synchronization status information reporting of a modality based on the preset conditions corresponding to the synchronization status information reporting of the modality, the synchronization status information report includes the synchronization status information of all modalities configured with the synchronization status information reporting.

[0096] In one embodiment, the priority of the synchronization status information is higher than that of a regular BSR or a periodic BSR, which helps ensure that the synchronization status information is sent in a timely manner. For example, the synchronization status information report and the delay status information report have the same resource allocation priority.

[0097] The above describes in detail the method for transmitting synchronization status information according to an embodiment of the present application in conjunction with FIG2 . The following describes in detail the method for transmitting synchronization status information according to another embodiment of the present application in conjunction with FIG3 . It is understood that the interaction between the network-side device and the terminal described from the perspective of the network-side device is the same as or corresponds to the description of the terminal side in the method shown in FIG2 . To avoid repetition, the relevant description is appropriately omitted.

[0098] FIG3 is a flow chart of a method for transmitting synchronization status information according to an embodiment of the present invention, which can be applied to a network-side device. As shown in FIG3 , the method 300 includes the following steps.

[0099] S302: The network side device sends a synchronization status information reporting configuration, where the synchronization status information reporting configuration is used for the terminal to send synchronization status information between multimodal data.

[0100] S304: The network-side device receives the synchronization status information.

[0101] In an embodiment of the present application, the network side device sends a synchronization status information reporting configuration, and the synchronization status information reporting configuration is used for the terminal to send synchronization status information between multi-modal data; the network side device receives the synchronization status information, which is beneficial to compensate for the synchronization deviation between data of different modes and is beneficial to the synchronous transmission of multi-modal data on the air interface.
