[0021] The technical solutions in the present application will be described below with reference to the accompanying drawings.

[0022] FIG. 1 is an example diagram of a system architecture of a wireless communication system 100 to which embodiments of the present application can be applied. The wireless communication system 100 can include a network device 110 and a terminal device 120. The network device 110 can be a device that communicates with the terminal device 120. The network device 110 can provide a communication coverage for a specific geographic area and can communicate with the terminal device 120 located in the coverage area.

[0023] FIG. 1 exemplarily shows one network device and two terminal devices, and optionally, the wireless communication system 100 can include a plurality of network devices and each network device can include other numbers of terminal devices within the coverage thereof, which are not limited by embodiments of the present application.

The terminal device in the embodiments of the present application can refer to a device that provides voice and / or data connectivity for a user, and can be used to connect people, things and machines, for example, handheld devices with wireless connection functions, vehicle-mounted devices, etc. The terminal device in the embodiments of the present application can be a mobile phone, a tablet computer (Pad), a notebook computer, a palm computer, a mobile internet device (MID), a wearable device, a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal in industrial control, a wireless terminal in self driving, a wireless terminal in remote medical surgery, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc. Optionally, the UE can be used to act as a base station. For example, the UE can act as a scheduling entity, which provides a sidelink signal between UEs in V2X or D2D, etc. For example, a cellular phone and a car communicate with each other using a sidelink signal. The cellular phone and the smart home device communicate with each other without relaying the communication signal through the base station.

[0027] The network device in the embodiments of the present application can be a device for communicating with a terminal device, which can also be referred to as an access network device or a radio access network device, such as a network device, which can be a base station. The network device in the embodiments of the present application can refer to a radio access network (RAN) node (or device) that accesses a terminal device to a wireless network. The base station can broadly cover various names in the following or be replaced by the following names, such as: Node B (NodeB), evolved Node B (eNB), next generation Node B (gNB), relay station, transmitting and receiving point (TRP), transmitting point (TP), master station MeNB, auxiliary station SeNB, multi-standard radio (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. The base station can be a macro base station, a micro base station, a relay node, a donor node or the like, or a combination thereof. The base station can also refer to a communication module, modem or chip for being disposed in the foregoing devices or apparatuses. The base station can also be a mobile switching center and a device that undertakes a base station function in device-to-device (D2D), vehicle-to-everything (V2X), machine-to-machine (M2M) communication, a network side device in a 6G network, a device that undertakes a base station function in a future communication system, etc. The base station can support networks of the same or different access technologies. The embodiments of the present application do not limit the specific technology and specific device form adopted by the network device.

[0028] The base station can be fixed or mobile. For example, a helicopter or a drone can be configured to act as a mobile base station, and one or more cells can move according to the location of the mobile base station. In other examples, the helicopter or the drone can be configured to act as a device that communicates with another base station.

[0029] In some deployments, the network device in the embodiments of the present application can refer to a CU or a DU, or the network device includes a CU and a DU. The gNB can also include an AAU.

[0030] The network device and the terminal device can be deployed on land, including indoor or outdoor, handheld or vehicle-mounted; can also be deployed on the water surface; can also be deployed on the aircraft, balloon and satellite in the air. The scene where the network device and the terminal device are located in the embodiments of the present application is not limited.

[0031] It should be understood that all or part of the functions of the communication device in the present application can also be implemented by software functions running on hardware, or by virtualized functions instantiated on a platform (such as a cloud platform).

[0032] In the NR system, when transmitting data between communication devices, the sending end can add cyclic redundancy check (CRC) information in the TB to ensure the integrity and reliability of the data. Correspondingly, the receiving end can determine whether the TB is correctly decoded based on the CRC information. In some embodiments, the CRC information can be TB-level CRC information.

[0033] In some embodiments, for the transmission of a large TB, a large TB (including TB-level CRC information) can be divided into multiple CBs, and each CB will also add a CRC information (CB-level CRC information). Then, the sending end can independently encode each CB with CRC information and concatenate them together. Correspondingly, the receiving end can independently decode each CB and determine whether the CB is correctly decoded based on the CB-level CRC information.

[0034] In order to improve the data retransmission efficiency, the NR system introduces CBG to support the generation of hybrid automatic repeat request-acknowledge (HARQ-ACK) information based on CBG. As an implementation manner, the NR system can divide the multiple CBs included in a TB into one or more CBGs, and each CBG in the one or more CBGs corresponds to 1 bit of HARQ-ACK information. That is, in the case that some CBGs in a TB are decoded unsuccessfully, only the CBGs that are decoded unsuccessfully can be scheduled for retransmission, without the need to retransmit the entire TB.

[0035] In a scenario of CBG-based HARQ-ACK generation, if any CB in a CBG fails to be decoded, the feedback information corresponding to the CBG is a negative acknowledgement (NACK); if all CBGs in a TB are successfully decoded but CRC check at the TB level fails or is not passed, the feedback information corresponding to all CBGs of the TB is NACK.

[0036] When CBG-based feedback is used, the smaller the feedback granularity (i.e., the smaller the granularity division of CBG), the higher the data retransmission efficiency. The most ideal state is to divide each CB into one CBG, i.e., each CB corresponds to 1 bit of feedback information. However, when the feedback granularity becomes smaller, the feedback overhead will increase accordingly. At present, the reliability requirement of feedback information is much higher than that of data, and therefore the capacity of uplink control signaling is usually not large, resulting in that the feedback granularity cannot be too small. Considering the downlink retransmission efficiency and uplink control signaling overhead comprehensively, in the NR system, a TB can be divided into at most 8 CBGs in single-codeword transmission, and a TB can be divided into at most 4 CBGs in dual-codeword transmission. That is, in the NR system, a physical downlink shared channel (PDSCH) corresponds to at most 8 bits of HARQ-ACK feedback information.

[0037] In the NR system, the CBs included in a TB are approximately evenly divided into one or more CBGs, wherein a CBG includes one CB or multiple continuous CBs. This grouping manner can cause some problems, such as affecting the retransmission efficiency of the TB.

[0038] From the above description, it can be seen that the grouping manner of approximately evenly dividing adjacent data in the to-be-transmitted data into a group is unreasonable when the communication device transmits data.

[0039] To solve the above problem, the embodiment of the present application provides a to-be-transmitted data grouping method, which can optimize the grouping manner of the to-be-transmitted data, thereby facilitating the improvement of the data retransmission efficiency. The to-be-transmitted data grouping method provided by the embodiment of the present application is introduced below.

[0040] In the embodiment of the present application, the to-be-transmitted data grouping method can be executed by a first device. To facilitate understanding, the first device is introduced first.

[0041] In some embodiments, the first device can be a sending end (hereinafter referred to as a sending end) of the to-be-transmitted data.

[0042] In some embodiments, the first device can be a receiving end (hereinafter referred to as a receiving end) of the to-be-transmitted data.

[0043] In some embodiments, the first device can be a terminal device, such as the terminal device 120 shown in FIG. 1.

[0044] In some embodiments, the first device can be a network device, such as the network device 110 shown in FIG. 1.

[0045] Taking the case that a network device sends to-be-transmitted data (downlink data) to a terminal device, the first device can be a sending end, i.e., the first device can be a network device; the first device can also be a receiving end, i.e., the first device can be a terminal device.

[0046] Taking the case that a terminal device sends to-be-transmitted data (uplink data) to a network device, the first device can be a sending end, i.e., the first device can be a terminal device; the first device can also be a receiving end, i.e., the first device can be a network device.

[0047] In the embodiments of the present application, the first device can determine the grouping related information (or referred to as related segment information, related block information, etc.) of the to-be-transmitted data.

[0048] In some embodiments, the to-be-transmitted data can include to-be-transmitted data carried by one or more TBs. In some embodiments, the to-be-transmitted data can include to-be-transmitted data carried by one or more CBs. In some embodiments, the one or more CBs can belong to the same TB. However, the embodiments of the present application are not limited thereto, for example, the to-be-transmitted data can be any to-be-transmitted data in the physical layer, such as to-be-transmitted data in a carrying unit with the same or similar function as a TB or a CB in a future communication system. For another example, the to-be-transmitted data can be any to-be-transmitted data in the radio link control (RLC) layer, such as a protocol data unit (PDU) or to-be-transmitted data in a carrying unit with the same or similar function as a PDU in a future communication system, or a service data unit (SDU) or to-be-transmitted data in a carrying unit with the same or similar function as an SDU in a future communication system, etc.

[0049] The embodiments of the present application do not limit the type of to-be-transmitted data. For example, the to-be-transmitted data can be to-be-transmitted data corresponding to a video frame. Or, the to-be-transmitted data can be to-be-transmitted data generated by browsing a webpage, etc.

[0050] In some embodiments, the grouping related information of the data to be transmitted can comprise one or more of the following: grouping information of the data to be transmitted, grouping information of the resources (or resources occupied by the channel carrying the data to be transmitted) carrying the data to be transmitted. That is, in the embodiments of the present application, the first device can group the data to be transmitted, and / or can group the resources carrying the data to be transmitted.

[0051] As an example, the first device determining the grouping related information of the data to be transmitted can comprise: the first device determining the grouping information of the data to be transmitted.

[0052] As another example, the first device determining the grouping related information of the data to be transmitted can comprise: the first device determining the grouping information of the resources carrying the data to be transmitted.

[0053] As yet another example, the first device determining the grouping related information of the data to be transmitted can comprise: the first device determining the grouping information of the data to be transmitted and the grouping information of the resources carrying the data to be transmitted.

[0054] The embodiments of the present application do not limit the content contained in the grouping related information of the data to be transmitted. Exemplarily, the grouping related information of the data to be transmitted can be related to one or more of the following: related information of CB, related information of CBG, related information of resource group.

[0055] In some embodiments, the grouping related information of the data to be transmitted can comprise one or more of the following: CB segment related information; number of CBs; CB size; number of CB groups; CB grouping manner; CBs included in a CBG; channel coding manner corresponding to a CBG; coding rate corresponding to a CBG; modulation manner corresponding to a CBG; modulation order corresponding to a CBG; redundancy version corresponding to a CBG; resource mapping manner corresponding to a CBG; number of resource groups; resource grouping manner; resources included in a resource group; number of CBs corresponding to a resource group; CB size corresponding to a resource group; CBs corresponding to a resource group; channel coding manner corresponding to a resource group; coding rate corresponding to a resource group; modulation manner corresponding to a resource group; modulation order corresponding to a resource group; redundancy version corresponding to a resource group; resource mapping manner corresponding to a resource group.

[0056] In some embodiments, the CB partitioning related information can be used to indicate the related information of the CBs, such as the number of CBs, the size of CBs, etc. For example, the first device needs to divide the data to be transmitted into one or more CBs, and the grouping related information of the data to be transmitted determined by the first device can include the CB partitioning related information. For another example, the first device needs to divide the data to be transmitted into one or more CBGs, and the grouping related information of the data to be transmitted determined by the first device can include the CB partitioning related information.

[0057] The indication granularity of the CB size is not limited in the embodiments of the present application. In some embodiments, the CB size can refer to the maximum size of the CBs. In some embodiments, the CB size can refer to the actual size of the CBs.

[0058] The number of CB groups can be one or more. For example, in the case that the first device divides the data to be transmitted into one CBG, the number of CB groups can be one. For another example, in the case that the first device divides the data to be transmitted into multiple CBGs, the number of CB groups can be multiple.

[0059] In some embodiments, the CB grouping manner can be used to indicate how different CBGs are divided, or in other words, the CB grouping manner can be used to indicate the grouping features of the data to be transmitted (such as multiple CBs). The CB grouping manner is not limited in the embodiments of the present application, and exemplary, the CB grouping manner can include one or more of the following: uniform grouping manner, uniform and continuous grouping manner, odd-even grouping manner, default grouping manner, and default grouping manner.

[0060] In some embodiments, after the data to be transmitted is divided into one or more CBGs according to the uniform grouping manner, the number of the data to be transmitted (such as CBs) included in each CBG is approximately uniform. For example, the data to be transmitted includes four consecutive CBs, CB1, CB2, CB3, and CB4. After the data to be transmitted is divided into two CBGs according to the uniform grouping manner, one CBG can include CB1 and CB2, and the other CBG can include CB3 and CB4; or, one CBG can include CB1 and CB4, and the other CBG can include CB2 and CB3; or, one CBG can include CB1 and CB3, and the other CBG can include CB2 and CB4.

[0061] In some embodiments, after the data to be transmitted is divided into one or more CBGs according to the uniform and continuous grouping manner, the number of the data to be transmitted (such as CBs) included in each CBG is approximately uniform and continuous CBs. For example, the data to be transmitted includes four consecutive CBs, CB1, CB2, CB3, and CB4. After the data to be transmitted is divided into two CBGs according to the uniform and continuous grouping manner, one CBG can include CB1 and CB2, and the other CBG can include CB3 and CB4.

[0062] In some embodiments, the number of the to-be-transmitted data included in each CBG can be approximately uniform or can be quite different after the to-be-transmitted data is divided into one or more CBGs according to the parity grouping manner. The embodiments of the present application are not limited in this regard. Taking an example in which the to-be-transmitted data includes four consecutive CBs, CB1, CB2, CB3 and CB4, and the to-be-transmitted data is divided into two CBGs according to the parity grouping manner, one CBG can include CB1 and CB3, and the other CBG can include CB2 and CB4. Taking an example in which the to-be-transmitted data includes five consecutive CBs, CB1, CB2, CB3, CB4 and CB5, and the to-be-transmitted data is divided into two CBGs according to the parity grouping manner, one CBG can include CB1, CB3 and CB5, and the other CBG can include CB2 and CB4.

[0063] The embodiments of the present application are not limited in the default grouping manner. In some embodiments, the default grouping manner can be understood as a grouping manner agreed by the protocol in advance. In some embodiments, the default grouping manner can be understood as a grouping manner agreed by the network device in advance. As an example, the default grouping manner can be one of the following grouping manners: the uniform grouping manner, the uniform and continuous grouping manner, the parity grouping manner, the default grouping manner.

[0064] In some embodiments, the default grouping manner can be understood as a grouping manner that explicitly indicates the to-be-transmitted data (such as CB) included in each CBG. For example, the default grouping manner can be understood as a grouping manner that explicitly indicates the index (or number) of the CB included in each CBG. In some embodiments, the default grouping manner can also be referred to as or understood as a specified grouping manner.

[0065] It should be noted that the above-mentioned CB grouping manners are only examples, and the CB grouping manners mentioned in the embodiments of the present application can also include other grouping manners, for example, the to-be-transmitted data can be divided into one or more CBGs according to the CB size, and the CB size included in each CBG is approximately the same.

[0066] In some embodiments, the CB included in one CBG can be used to indicate the related information of the CB included in one CBG. For example, the CB included in one CBG can be used to indicate one or more of the following: the index of the CB included in one CBG, the number of the CB included in one CBG, the size of the CB included in one CBG, and the like.

[0067] In some embodiments, a CBG can be directly indicated to achieve a better grouping. This is because the indexes of CBs with correlation are likely to be non-continuous and the number is also non-uniform, in which case, it is more intuitive to directly indicate the CBs included in a CBG, and the grouping result is better. For example, the CBs on the same frequency domain resource have strong correlation, and when a plurality of CBs are cascaded and resource mapping is performed in the order of frequency domain and then time domain, adjacent CBs do not occupy the same frequency domain resource. In this case, the CB grouping manner can be indicated by directly indicating the CBs included in a CBG (such as the indexes of the CBs).

[0068] The embodiments of the present application do not limit the channel coding manner corresponding to a CBG. For example, the channel coding manner corresponding to a CBG can include one or more of the following: polar code encoding manner, low density parity check (LDPC) code encoding manner, and the like. Of course, the channel coding manner corresponding to a CBG can also include the channel coding manner in future communication systems.

[0069] The embodiments of the present application do not limit the resource mapping manner corresponding to a CBG. For example, the resource mapping manner corresponding to a CBG can include one of the following: time domain first and then frequency domain mapping, frequency domain first and then time domain mapping, and the like.

[0070] In some embodiments, after the to-be-transmitted data is divided into one or more CBGs, different CBGs can be differentially configured to make the performance of different CBGs similar. For example, the channel configuration or resource configuration corresponding to CBGs with different channel fading characteristics can be different. For example, after the to-be-transmitted data is divided into one or more CBGs, one or more of the channel coding manner, coding rate, modulation manner, modulation order, redundancy version, and resource mapping manner corresponding to a CBG can be differentially configured. As an example, for a CBG in deep fading (or large-scale fading, fast fading), a lower coding rate, a more reliable redundancy version, and the like can be used.

[0071] In some embodiments, differentially configuring the channel or resource of a CBG can mean differentially configuring the channel or resource of any (or at least one) CBG in a plurality of CBGs to reduce overhead. For example, channel configuration or resource configuration can be performed only for CBGs with obvious differences, and other groups use preconfigured or default channel configuration or resource configuration. As an example, the coding rate in the model input information can be used as a default value, and the coding rate of one or more CBGs can be adjusted (i.e., differentially configured) after model processing. The related content of the model can be referred to in the following description, which is not described in detail here.

[0072] The implementation of the embodiment of the present application does not limit the manner of differentially configuring one CBG. As an implementation, when one CBG is differentially configured, the configuration value corresponding to the CBG can be indicated. Taking the differential configuration of the coding rate of the CBG as an example, the coding rate corresponding to the CBG can be indicated. As another implementation, when one CBG is differentially configured, the difference value of the CBG relative to the default value can be indicated. Still taking the differential configuration of the coding rate of the CBG as an example, the difference value of the CBG relative to the default coding rate can be indicated.

[0073] It should be noted that the above-mentioned one CBG can be any one of the plurality of CBGs, or each of the plurality of CBGs. That is, the above-mentioned one CBG can be replaced by one or more of the following: one or more CBGs, at least one CBG, and each CBG. Taking the CB included in one CBG as an example, the CB included in one CBG can refer to the CB included in any one of the plurality of CBGs, or the CB included in each of the plurality of CBGs. Taking the channel coding mode corresponding to one CBG as an example, the channel coding mode corresponding to one CBG can refer to the channel coding mode corresponding to any one of the plurality of CBGs, or the channel coding mode corresponding to each of the plurality of CBGs. For brevity, other examples are not described.

[0074] The number of resource groups can be one or more. For example, when the first device divides the resources carrying the to-be-transmitted data into one resource group, the number of resource groups can be one. For another example, when the first device divides the resources carrying the to-be-transmitted data into multiple resource groups, the number of resource groups can be multiple.

[0075] In some embodiments, the resource grouping manner can be used to indicate how different resource groups are divided, or in other words, the resource grouping manner can be used to indicate the grouping characteristics of the resources carrying the to-be-transmitted data. The embodiment of the present application does not limit the resource grouping manner, and exemplary resource grouping manners can include one or more of the following: time domain grouping manner, frequency domain grouping manner, time-frequency grouping manner, and antenna port grouping manner.

[0076] In some embodiments, the time domain grouping manner can be understood as that the resources carrying the to-be-transmitted data are divided into one or more resource groups according to time domain characteristics, or in other words, the resources carrying the to-be-transmitted data are divided into one or more resource groups in the time domain.

[0077] In some embodiments, the frequency domain grouping manner can be understood as that the resources carrying the data to be transmitted are divided into one or more resource groups according to the frequency domain characteristics, or in other words, the resources carrying the data to be transmitted are divided into one or more resource groups in the frequency domain.

[0078] In some embodiments, the time-frequency grouping manner can be understood as that the resources carrying the data to be transmitted are divided into one or more resource groups according to the time domain and frequency domain characteristics, or in other words, the resources carrying the data to be transmitted are divided into one or more resource groups in the time domain and frequency domain. In some embodiments, the time-frequency grouping manner can also be referred to as a time-frequency two-dimensional grouping manner. In some embodiments, when grouping the resources carrying the data to be transmitted according to the time-frequency grouping manner, the resources can be indexed in the order of the frequency domain first and then the time domain, or in the order of the time domain first and then the frequency domain, and the embodiments of the present application are not limited thereto.

[0079] In some embodiments, the antenna port grouping manner can be understood as that the resources carrying the data to be transmitted are divided into one or more resource groups according to the characteristics of the antenna ports. In some embodiments, the antenna port grouping manner can be understood as a manner of dividing resources according to the space domain characteristics.

[0080] In some embodiments, the resources included in a resource group can be used to indicate the related information of the resources included in the resource group. For example, the resources included in a resource group can be used to indicate one or more of the following: the number of resources included in a resource group, the index of the resources included in a resource group, and the like.

[0081] In some embodiments, the number of resources included in a resource group and the resource grouping manner can obtain an approximately uniform resource grouping result. In this case, the index of the resources included in each configured resource group can not be indicated to save signaling overhead. For example, the resource grouping manner is the frequency domain grouping manner, and the number of resources included in a resource group is indicated as 4 resource blocks (RBs), which means that every 4 RBs are grouped in the frequency domain dimension. For another example, the resource grouping manner is the time-frequency grouping manner, and the number of resources included in a resource group is indicated as 2 symbols and 4 RBs, which means that 2 symbols and 4 RBs are grouped in the time-frequency two-dimensional dimension.

[0082] In some embodiments, if the number of resources included in a resource group is insufficient for the last group of remaining resources, the group can be independently grouped, or can be combined with the previous group into a group. Taking the frequency domain grouping manner as an example, if the number of resources included in a resource group is insufficient for the last group, the group can be independently grouped, or can be combined with the previous group into a group. Taking the time-frequency grouping manner as an example, if the number of resources included in a resource group is insufficient for the last group, the group can be independently grouped, or can be combined with the previous group into a group.

[0083] In some embodiments, the number of resources included in one resource group can be used to indicate the number of resources included in each of the plurality of resource groups. That is, the plurality of resource groups can correspond to one value, which is used to indicate the number of resources included in each of the plurality of resource groups. In some embodiments, this implementation can implement uniform grouping of resources, and this implementation has small signaling overhead and poor flexibility.

[0084] In some embodiments, the number of resources included in one resource group can be used to indicate the number of resources included in any one of the plurality of resource groups. That is, the plurality of resource groups can correspond to a plurality of values (each of the plurality of resource groups corresponds to one value), and the plurality of values are respectively used to indicate the number of resources included in each of the plurality of resource groups. In some embodiments, this implementation can implement non-uniform grouping of resources, and this implementation has high flexibility and large signaling overhead.

[0085] In some embodiments, the resource grouping result can be indicated by directly indicating the index of the resource included in one resource group.

[0086] In some embodiments, the number of CBs corresponding to one resource group can be understood as the number of CBs carried in one resource group or the number of CBs mapped into one resource group.

[0087] In some embodiments, the CB size corresponding to one resource group can be understood as the size of the CB carried in one resource group or the size of the CB mapped into one resource group. For example, the CB size corresponding to one resource group can be understood as the actual size of the CB carried in one resource group, or the maximum size of the CB carried in one resource group. In some embodiments, the CB size corresponding to one resource group can refer to the total size of all CBs corresponding to the resource group, or can refer to the size of each CB corresponding to the resource group.

[0088] In some embodiments, the CB corresponding to one resource group can be used to indicate the related information of the CB included in one resource group. For example, the CB corresponding to one resource group can be used to indicate one or more of the following: the index of the CB included in one resource group, the number of CBs included in one resource group, the size of the CB included in one resource group, etc. In some embodiments, the CB corresponding to one resource group can be understood as the CB carried in one resource group or the CB mapped into one resource group.

[0089] The embodiments of the present application do not limit the channel coding mode corresponding to one resource group. Exemplarily, the channel coding mode corresponding to one resource group can include one or more of the following: a polar code coding mode, an LDPC code coding mode, and the like. Of course, the channel coding mode corresponding to one resource group can also include a channel coding mode in a future communication system.

[0090] The embodiments of the present application do not limit the resource mapping mode corresponding to one resource group. Exemplarily, the resource mapping mode corresponding to one resource group can include one of the following: time domain first and frequency domain second mapping, frequency domain first and time domain second mapping, and the like.

[0091] In some embodiments, after the resources carrying the data to be transmitted are divided into one or more resource groups, different resource groups can be configured differently, aiming to make the performance of different resource groups similar. For example, the channel configuration or resource configuration corresponding to resource groups with different channel fading characteristics can be different. Exemplarily, after the resources carrying the data to be transmitted are divided into one or more resource groups, one or more of the channel coding mode, coding rate, modulation mode, modulation order, redundancy version, and resource mapping mode corresponding to one resource group can be configured differently. As an example, for a resource group in deep fading (or large-scale fading, fast fading), a lower coding rate, a more reliable redundancy version, and the like can be used.

[0092] In some embodiments, differentially configuring the channel or resources of one resource group can mean differentially configuring the channel or resources of any (or at least one) resource group in the plurality of resource groups, to reduce overhead. For example, channel configuration or resource configuration can be performed only for resource groups with significant differences, and other groups use preconfigured or default channel configuration or resource configuration. As an example, the coding rate in the model input information can be used as a default value, and the coding rate of one or more resource groups can be adjusted (i.e., differentially configured) after model processing. The related content of the model can be referred to in the following introduction, which is not described in detail here.

[0093] The embodiments of the present application do not limit the implementation of differentially configuring one resource group. As an implementation, when differentially configuring one resource group, the configuration value corresponding to the resource group can be indicated. Taking differentially configuring the coding rate of a resource group as an example, the coding rate corresponding to the resource group can be indicated. As another implementation, when differentially configuring one resource group, the difference of the resource group relative to the default value can be indicated. Still taking differentially configuring the coding rate of a resource group as an example, the difference of the resource group relative to the default coding rate can be indicated.

[0094] It should be noted that the above-mentioned one resource group can be any one of the plurality of resource groups, or each of the plurality of resource groups. That is, the above-mentioned one resource group can be replaced by one or more of the following: one or more resource groups, at least one resource group, and each resource group. Taking the resources included in one resource group as an example, the resources included in one resource group can refer to the resources included in any one of the plurality of resource groups, or the resources included in each of the plurality of resource groups. Taking the channel coding mode corresponding to one resource group as an example, the channel coding mode corresponding to one resource group can refer to the channel coding mode corresponding to any one of the plurality of resource groups, or the channel coding mode corresponding to each of the plurality of resource groups. For the sake of brevity, other examples are not described.

[0095] In some embodiments, after grouping the resources carrying the data to be transmitted, the first device can map one CB to one resource group for transmission. In some embodiments, this approach is applicable to the case where the channel configuration or resource configuration used by different resource groups is independently configured, for example, the case where one or more of the channel coding mode, coding rate, modulation mode, modulation order, redundancy version, resource mapping mode, and the like used by different resource groups is independently configured.

[0096] In some embodiments, after grouping the resources carrying the data to be transmitted, the first device can map one CB to different resource groups (multiple resource groups) for transmission. In some embodiments, the channel configuration or resource configuration corresponding to the different resource groups to which the one CB is mapped is the same, for example, one or more of the channel coding mode, coding rate, modulation mode, modulation order, redundancy version, resource mapping mode, and the like used by the different resource groups is the same.

[0097] In some embodiments, after grouping the data to be transmitted, the data in each data group to be transmitted has correlation, and the data in different data groups to be transmitted has difference. Taking the case where the first device divides the data to be transmitted into a plurality of CBGs as an example, the data in each CBG has correlation, and the data in different CBGs has difference. Taking the case where the first device divides the resources carrying the data to be transmitted into a plurality of resource groups as an example, the channel conditions or interference conditions in each resource group are similar, and the channel conditions or interference conditions of different resource groups have difference.

[0098] The grouping related information of the data to be transmitted is introduced above, and how the first device determines the grouping related information of the data to be transmitted is introduced below.

[0099] In some embodiments, the first device can determine the grouping related information of the data to be transmitted according to the transmission parameters.

[0100] In some embodiments, the first device can determine the packet related information of the data to be transmitted according to the first model.

[0101] In some embodiments, the first device can determine the packet related information of the data to be transmitted according to the transmission parameter and the first model.

[0102] The transmission parameter and the first model are introduced respectively as follows.

[0103] In some embodiments, the transmission parameter can include one or more of the following: a parameter of the data to be transmitted, a parameter of the resource occupied by the data to be transmitted. In some embodiments, the parameter of the resource occupied by the data to be transmitted can also be understood as a parameter of the resource occupied by the channel carrying the data to be transmitted. This is because the inventors have found that the correlation of the decoding results of the data to be transmitted can be affected by various factors, such as channel conditions, resources occupied by the data to be transmitted (for example, the channel conditions on adjacent subcarriers are similar), etc. Therefore, when grouping the data to be transmitted, the parameters of the data to be transmitted and / or the parameters of the resources occupied by the data to be transmitted can be considered, which is beneficial to ensure that the data or resources in the group have correlation and the data or resources between groups have difference after grouping. Taking the case of dividing the data to be transmitted into one or more CBGs as an example, if the CBG is taken as the minimum granularity of data retransmission, the higher the correlation of the decoding results of the CBs in the same CBG is, the better it is. That is, if the CBG is taken as the minimum granularity of data retransmission, the CBs that are simultaneously wrong or simultaneously correct should be divided into a CBG as much as possible, so that the correlation of the decoding results of the CBs in the same CBG will be higher. In this way, it is beneficial to improve the efficiency of data retransmission.

[0104] The present application does not make specific limitations on the transmission parameter. Exemplarily, the transmission parameter can include one or more of the following: a data amount of the data to be transmitted, a number of CBs contained by the data to be transmitted, a CB size contained by the data to be transmitted, a modulation mode corresponding to the data to be transmitted, a modulation order corresponding to the data to be transmitted, a coding rate corresponding to the data to be transmitted, a number of resources occupied by the data to be transmitted, a location of the resources occupied by the data to be transmitted, a coding of the resources occupied by the data to be transmitted, a service characteristic of the data to be transmitted, precoding information corresponding to the data to be transmitted, a resource mapping mode corresponding to the data to be transmitted, an interleaving mode corresponding to the data to be transmitted, whether the data to be transmitted supports retransmission, a feedback mode corresponding to the data to be transmitted, redundancy version information corresponding to the data to be transmitted, and a channel coding mode corresponding to the data to be transmitted.

For example, when the data to be transmitted includes a TB, the data amount of the data to be transmitted can refer to a TB size (TBS). However, the embodiments of the present application are not limited thereto, for example, the data amount of the data to be transmitted can refer to a payload of the data to be transmitted, and the like.

[0106] In some embodiments, the data amount of the data to be transmitted can be indicated by a number of bits.

[0107] The embodiments of the present application do not limit the value of the data amount of the data to be transmitted. In some embodiments, the data amount of the data to be transmitted can be a certain value, for example, the data amount of the data to be transmitted is 1000 bits. In some embodiments, the data amount of the data to be transmitted can be a value range, for example, the data amount of the data to be transmitted is 1000-1500 bits.

[0108] In some embodiments, the number of CBs contained in the data to be transmitted and / or the CB size can be a reference number and / or a reference size. For example, the reference number and / or the reference size can be used as a model input, and the model can determine the number of CBs contained in the actual packet and / or the CB size based on the reference number and / or the reference size and other parameters. In some embodiments, the reference number and / or the reference size described above can be the same as the number of CBs contained in the actual packet and / or the CB size. In some embodiments, the reference number and / or the reference size described above can be different from the number of CBs contained in the actual packet and / or the CB size.

[0109] In some embodiments, the resources occupied by the data to be transmitted can include one or more of the following: time domain resources, frequency domain resources, space domain resources, code domain resources.

In some implementations, when the feedback granularity corresponding to the to-be-transmitted data is independent feedback, the feedback information corresponding to one channel or one data or one transmission is transmitted independently.

In some embodiments, the feedback granularity corresponding to the to-be-transmitted data can include one or more of the following: TB-level feedback, CB-level feedback, CBG-level feedback. In some implementations, when the feedback granularity corresponding to the to-be-transmitted data is TB-level feedback, one TB corresponds to 1 bit of feedback information.

[0120] In some embodiments, the resource carrying the feedback information can include one or more of the following: a physical resource carrying the feedback information, a channel format carrying the feedback information, and a channel capacity carrying the feedback information.

[0121] In some embodiments, the generation mode of the feedback information can be indicated by indicating the codebook type of the feedback information.

[0122] In some embodiments, the above-mentioned feedback information can include HARQ-ACK information.

[0123] The embodiments of the present application do not make specific limitations on the channel coding mode corresponding to the to-be-transmitted data. Exemplarily, the channel coding mode can include one or more of the following: polar code, LDPC code. Of course, the channel coding mode can also include the channel coding mode in future communication systems.

[0124] The first model of the embodiments of the present application is described in detail below.

[0125] FIG. 2 is an example diagram of the architecture of the first model provided by the embodiments of the present application. As shown in FIG. 2, the first model can receive the above-mentioned transmission parameters and output the grouping-related information of the to-be-transmitted data after model processing. That is, in some embodiments, the above-mentioned transmission parameters can be used as the input information of the first model, and the grouping-related information of the to-be-transmitted data can be used as the output information of the first model.

[0128] In some embodiments, the first model can be deployed on the first device side. For example, the first model can be deployed only on the first device side (single-end deployed model). For another example, the first model can be deployed on the first device side and the opposite side of the first device (double-end deployed model). Taking the first device as the sending end as an example, the opposite side of the first device can refer to the receiving end. Taking the first device as the receiving end as an example, the opposite side of the first device can refer to the sending end.

[0129] In some embodiments, in the scenario of the single-end deployed model, the first model can be deployed on the receiving end.

[0136] Implementation 1: The second information is used to indicate the first model

[0137] In some embodiments, the network device or the terminal device can send the second information to indicate the first model.

[0140] Implementation 2: The second information is used to activate the first model

[0141] The network device or the terminal device can send the second information to activate the first model. That is, the first device can receive the second information sent by the network device or the terminal device, and the second information is used to activate the first model. Taking the first device as a terminal device as an example, the first device can receive the second information (such as configuration information) sent by the network device to activate the first model. Taking the first device as a network device as an example, the first device can receive the second information (such as information reported by the terminal device) sent by the terminal device to activate the first model.

[0142] In some embodiments, the first model can be one of a plurality of pre-configured models. In this case, the network device or the terminal device can activate the first model through the second information, that is, activate one of the plurality of pre-configured models.

[0143] In some embodiments, the plurality of models described above are different models. For example, the plurality of models described above have different identifiers. For example, the plurality of models described above have different functions.

[0144] In some embodiments, the application scenarios of the plurality of models described above can be different. In some embodiments, the application scenario of the model can be affected by one or more factors. Exemplarily, the application scenario of the model can be affected by one or more of the following factors: service characteristics, channel transmission characteristics, characteristics of a serving cell, capabilities of a terminal device, etc.

[0145] The application embodiments do not limit the indication manner of the service characteristics. Exemplarily, the service characteristics can be indicated by one or more of the following: data volume corresponding to the service, reliability requirement of the service, latency requirement of the service, priority of the service, etc.

[0146] The application embodiments do not limit the indication manner of the channel transmission characteristics. Exemplarily, the channel transmission characteristics can be indicated by one or more of the following: antenna configuration, spatial channel characteristics, interference level, moving speed of a communication device, channel fading characteristics, etc. In some embodiments, the channel transmission characteristics can include uplink channel transmission characteristics and / or downlink channel transmission characteristics.

Exemplarily, the characteristics of the serving cell can be indicated by one or more of the following: cell coverage, capability of the network device to which the cell belongs, version of the network device to which the cell belongs, and working mode of the cell. In some embodiments, the working mode of the cell can include one or more of the following: single-carrier working mode, carrier aggregation working mode.

[0148] The embodiments of the present application do not limit the pre-configuration manner of the plurality of models. In some embodiments, the plurality of models can be agreed by a protocol. In some embodiments, the plurality of models can be configured by a network device. In some embodiments, the plurality of models can be reported by a terminal device.

[0149] The embodiments of the present application do not limit the carrying manner of the second information. Exemplarily, the second information can be carried in one or more of the following: radio resource control (RRC) signaling, media access control control element (MAC CE), downlink control information (DCI), uplink control information (UCI), and terminal device capability information. For example, the second information is used to indicate the first model, and the second information can be carried in one or more of the following: RRC signaling, MAC CE, DCI, UCI, and terminal device capability information. For another example, the second information is used to activate the first model, and the second information can be carried in one or more of the following: MAC CE, DCI, and UCI.

[0150] In some embodiments, the second information can be periodically sent, or in other words, the sending position of the second information has periodicity. That is, the second information can be sent on a periodic resource, but it is not necessarily sent every period.

[0151] The embodiments of the present application do not limit the validity time of the indication result of the second information (which can also be understood as the validity time of the first model indicated by the second information). In some embodiments, the validity time of the indication result of the second information can be determined by one or more of the following: protocol agreement, network device configuration, and terminal device reporting. For example, the validity time of the indication result of the second information is T, and the length of T can be determined by one or more of the following: protocol agreement, network device configuration, and terminal device reporting.

[0152] The indication manner of the validity time of the indication result of the second information is not limited in the embodiments of the present application. As an example, the network device or the terminal device can indicate the validity time of the indication result of the second information in the second information. As another example, the network device or the terminal device can indicate the validity time of the indication result of the second information by using a separate DCI or UCI.

[0153] In some embodiments, the validity time of the indication result of the second information can be a fixed-length time. For example, the protocol can agree that the validity time of the indication result of the second information is 10 seconds. Alternatively, the network device can configure the validity time of the indication result of the second information as 10 seconds. Alternatively, the terminal device can report the validity time of the indication result of the second information as 10 seconds.

[0154] In some embodiments, the validity time of the indication result of the second information can be a variable value. For example, the protocol can agree or the network device can configure or the terminal device can report that the indication result of the previous second information is valid before a new second information is received. In other words, the end position of the validity time of the indication result of the second information can be the position of receiving a new second information.

[0155] In some embodiments, the indication result of the second information is used only once, that is, the indication result of the second information is valid for a single time. For example, the network device sends the second information in the DCI, and the model indicated by the second information is applicable to the PDSCH or PUSCH (or the data carried by the PDSCH or PUSCH) scheduled by the DCI. For another example, the terminal device sends the second information in the PUSCH, and the model indicated by the second information is applicable to the PUSCH (or the data carried by the PUSCH). For another example, the terminal device sends the second information at the same time when sending the HARQ-ACK information for the downlink data, and the model indicated by the second information is applicable to the downlink data.

[0156] In some embodiments, the network device and the terminal device can confirm the reception of the second information to ensure that the understanding of the subsequent used model by both parties is consistent. For example, in the case that the indication result of the second information is valid for a long time, the network device and the terminal device can confirm the reception of the second information. For another example, in the case that the indication result of the second information is valid for a single time, the network device and the terminal device can confirm the reception of the second information to ensure that the understanding of the subsequent used model by both parties is consistent, or can not confirm the reception of the second information to save signaling overhead.

[0157] Implementation 3: determining a first model from a plurality of models according to a first rule

[0158] In some embodiments, the first device can determine a first model from a plurality of preconfigured models according to a first rule.

[0163] The embodiments of the present application do not make specific limitation to the transmission condition corresponding to the feedback information. Illustratively, the transmission condition corresponding to the feedback information can be related to whether and / or how the channels for transmitting the feedback information are multiplexed.

[0164] In order to facilitate understanding, several examples of the first rule are given below.

[0165] As an example, if the data amount of the data to be transmitted is greater than or equal to a first numerical value or belongs to a first value range, the first device determines that the first model is Model A.

[0166] As an example, if the number of CBs contained in the data to be transmitted is greater than or equal to a second numerical value or belongs to a second value range, the first device determines that the first model is Model A.
