[0035] Currently, communication systems typically have various service transmission requirements, such as Extended Reality (XR), Ultra-Reliable and Low-Latency Communication (URLLC), Enhanced Mobile Broadband (eMBB), and Massive Machine-Type Communication (mMTC). These different services have varying performance requirements, such as different demands on latency, reliability, and bandwidth. For example, URLLC and XR services require high reliability and low latency, eMBB services require high bandwidth, and mMTC services require low bandwidth.

[0036] In related technologies, terminal devices can transmit services with different performance requirements across multiple physical channels using time-division multiplexing. While this allows service data with varying performance requirements to be transmitted through independent physical channels to meet the needs of different services, the overall signaling overhead for scheduling is significant, resulting in low transmission efficiency. Alternatively, terminal devices can mix and encode service data with different performance requirements and then perform HARQ retransmission; however, since the base station schedules services based on reliability, this leads to overall low transmission efficiency.

[0037] In the communication methods, apparatus, devices, systems, media, and computer program products provided in the embodiments of this application, the terminal device sends first information to indicate to the receiving end that the first data unit carried by the first channel contains N sub-units of service data with different performance requirements, so that the receiving end can accurately and efficiently receive the service data with different performance requirements contained in the N sub-units based on the first information, thereby improving the transmission efficiency of services with different performance requirements.

[0038] The communication method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0039] Figure 2 is a flowchart illustrating a communication method provided in some embodiments of this application. As shown in Figure 2, the communication method may include the following step 201:

[0040] Step 201: The terminal device sends the first information.

[0041] In some embodiments of this application, the first information is used to indicate the relevant information of the N sub-units included in the first data unit, where N is an integer greater than 1.

[0042] In some embodiments of this application, the first data unit described above is carried in a first channel.

[0043] In some embodiments of this application, the first channel described above can be a data channel. For example, the data channel can be a Physical Uplink Shared Channel (PUSCH).

[0044] In some embodiments of this application, the above-mentioned N sub-units constitute the first data unit.

[0045] In some embodiments of this application, the first data unit described above may be any of the following: codeword, TB, HARQ process, or channel.

[0046] For example, a codeword may include at least one TB. A TB may include at least one CB. A TB may include at least one CBG. A CBG may include at least one CB. A HARQ process may include at least one sub-HARQ process. A channel may include at least one sub-channel.

[0047] In some embodiments of this application, the first data unit is a codeword, and the sub-unit is at least one of the following: TB, CB, CBG.

[0048] In some embodiments of this application, the first data unit is TB, and the sub-unit is at least one of the following: CB, CBG.

[0049] In some embodiments of this application, the first data unit is a HARQ process, and the sub-unit is at least one of the following: HARQ sub-process, TB, CB, CBG.

[0050] In some embodiments of this application, the first data unit is a channel, and the sub-unit is at least one of the following: sub-channel, HARQ sub-process, TB, CB, CBG.

[0051] In some embodiments of this application, the terminal device may send first information to the network device.

[0052] In some embodiments of this application, the first information and the first data unit can be transmitted through the first channel; wherein the first information is encoded independently of the first data unit. That is, the terminal device can transmit the first information and the first data unit on the first channel. Thus, by encoding the first information independently of the first data unit during the transmission of the first information and the first data unit through the first channel, both signaling overhead and data transmission reliability can be reduced.

[0053] In some embodiments of this application, the first information is independent of the encoding of the first data unit. This can be understood as the terminal device encoding the first information and encoding the first data unit separately, that is, the terminal device does not encode the first information and the first data unit as a whole.

[0054] In some embodiments of this application, the first information and the first data unit can be transmitted through different channels. That is, the terminal device can transmit the first data unit on the first channel and transmit the first information on the second channel, wherein the first channel and the second channel are different channels.

[0055] In some embodiments of this application, the above-mentioned N sub-units may be N sub-units of service data with different performance requirements contained in the first data unit.

[0056] In some embodiments of this application, the data volume of the above N sub-units is related to the first parameter of the network device configuration.

[0057] In some embodiments of this application, the first parameter described above can be determined based on first configuration information configured on the network side.

[0058] For example, the first configuration information mentioned above may include at least one of the following: Downlink Control Information (DCI), Radio Resource Control (RRC) signaling, and Media Access Control Layer Control Element (MAC CE).

[0059] It should be noted that the first parameter mentioned above can be directly indicated by the first configuration information or indirectly indicated by the first configuration information. The specific method can be determined according to actual needs, and this embodiment does not impose any restrictions here.

[0060] In some embodiments of this application, the first parameter can be a first number of bits. The number of bits in the N sub-units is less than or equal to this first number of bits. That is, the total number of bits in the N sub-units is less than or equal to the first number of bits.

[0061] In some embodiments of this application, the aforementioned first bit count is any one of the following: the total number of bits in the first data unit; the reference bit count; or the number of bits configured in the network device. It should be noted that the total number of bits in the aforementioned N sub-units can also be approximately equal to the aforementioned first bit count.

[0062] For example, the first configuration information mentioned above can indicate the modulation and coding scheme (MCS) and the amount of transmission resources, and the terminal device can calculate the first bit quantity based on the MCS and the amount of transmission resources mentioned above.

[0063] In some embodiments of this application, the first parameter can be the number of first coded blocks. Specifically, the number of coded blocks in the N sub-units is less than or equal to the number of first coded blocks. That is, the total number of coded blocks in the N sub-units is less than or equal to the number of first coded blocks.

[0064] For example, the first configuration information can indicate the number of MCS and transmission resources, and the terminal device can calculate the number of the first coding blocks based on the number of MCS and transmission resources.

[0065] In some embodiments of this application, the number of the first coding blocks is any one of the following: the total number of coding blocks of the first data unit; the number of reference coding blocks; the number of coding blocks configured by the network device. It should be noted that the total number of coding blocks of the N sub-units can also be approximately equal to the number of the first coding blocks.

[0066] In this way, the terminal device can determine the number of bits or codes required to transmit a data unit by using the first parameter configured by the network device. This makes the N sub-units sent by the terminal device based on the number of bits or codes more consistent with the actual situation of the network, thereby improving the transmission efficiency of the N sub-units.

[0067] In some embodiments of this application, the amount of resources occupied by the above-mentioned N sub-units is related to the second parameter configured by the network-side device.

[0068] In some embodiments of this application, the second parameter described above can be determined based on second configuration information configured on the network side.

[0069] For example, the second parameter can indicate the first resource quantity. The total number of resources occupied by the N sub-units is less than or equal to the first resource quantity. That is, the total number of resources occupied by the N sub-units is less than or equal to the first resource quantity.

[0070] In some embodiments of this application, the aforementioned first resource quantity is any one of the following: the total resource quantity occupied by the aforementioned first data unit; a reference resource quantity; or the resource quantity configured in the network device. It should be noted that the total resource quantity occupied by the aforementioned N sub-units can also be approximately equal to the aforementioned first resource quantity.

[0071] In some embodiments of this application, the second configuration information described above may include at least one of the following: DCI, RRC signaling, and MAC CE.

[0072] In some embodiments of this application, the resources occupied by the first data unit may include at least one of the following: time-domain resources, frequency-domain resources, and resource elements (REs).

[0073] It should be noted that the second parameter mentioned above can be directly indicated by the second configuration information mentioned above, or it can be indirectly indicated by the second configuration information mentioned above. The specific method can be determined according to actual needs, and this embodiment does not impose any restrictions here.

[0074] In some embodiments of this application, the second parameter can be directly indicated by the second configuration information, which can be understood as the second configuration information directly including the first resource quantity.

[0075] In some embodiments of this application, the second parameter can be indirectly indicated by the second configuration information, which can be understood as: the second configuration information directly indicates the resources occupied by the first data unit without indicating the quantity of the first resources.

[0076] In some embodiments of this application, the number of resources occupied by the above-mentioned N sub-units is less than or equal to the total number of resources occupied by the first data unit, including at least one of the following: the number of time-domain resources occupied by the above-mentioned N sub-units is less than or equal to the number of first time-domain resources; the number of frequency-domain resources occupied by the above-mentioned N sub-units is less than or equal to the number of first frequency-domain resources; the number of REs occupied by the above-mentioned N sub-units is less than or equal to the number of first REs of the network device.

[0077] In some embodiments of this application, the first time-domain resource quantity can be any of the following: the total number of time-domain resources occupied by the first quantity unit; the reference number of time-domain resources; or the number of time-domain resources configured by the network device.

[0078] In some embodiments of this application, the aforementioned first frequency domain resource quantity can be any of the following: the total number of frequency domain resources occupied by the first quantity unit; the number of reference frequency domain resources; or the number of frequency domain resources configured by the network device.

[0079] In some embodiments of this application, the first RE number can be any of the following: the total number of REs occupied by the first quantity unit; the reference RE number; the number of REs configured in the network device.

[0080] In some embodiments of this application, the number of time-domain resources occupied by the aforementioned N sub-units can be understood as the total number of time-domain resources occupied by the aforementioned N sub-units. That is, the total number of time-domain resources occupied by the aforementioned N sub-units is less than or equal to the first number of time-domain resources.

[0081] For example, if the number of resources in the first time domain is 200, then the total number of time domain resources occupied by the above N sub-units can be 100.

[0082] In some embodiments of this application, the number of frequency domain resources occupied by the aforementioned N sub-units can be understood as the total number of frequency domain resources occupied by the aforementioned N sub-units. That is, the total number of frequency domain resources occupied by the aforementioned N sub-units is less than or equal to the number of first frequency domain resources.

[0083] For example, if the number of resources in the first time domain is 100, then the total number of time domain resources occupied by the above N sub-units can be 90.

[0084] In some embodiments of this application, the number of REs occupied by the aforementioned N sub-units can be understood as the total number of REs occupied by the aforementioned N sub-units. That is, the total number of REs occupied by the aforementioned N sub-units is less than or equal to the first number of REs.

[0085] For example, if the first RE quantity is 50, then the total number of REs occupied by the above N sub-units can be 50.

[0086] In this way, the terminal device can determine the amount of resources occupied by a data unit by using the second parameter configured by the network device, so that the N sub-units sent by the terminal device based on the total amount of resources are more in line with the actual situation of the network, thereby improving the transmission efficiency of the N sub-units.

[0087] In some embodiments of this application, the aforementioned related information includes at least one of the following: the value of N; the division method of the N sub-units; the division parameters of the N sub-units; the data volume information of at least one of the N sub-units; and the resource information of at least one of the N sub-units.

[0089] It should be noted that the total number of bits in the above N sub-units can also be approximately equal to the first number mentioned above; the total number of coded blocks in the above N sub-units can also be approximately equal to the second number mentioned above; and the total number of resources occupied by the above N sub-units can also be approximately equal to the third number mentioned above.

[0091] In some embodiments of this application, the first quantity is determined based on the configuration parameters of the network device; the second quantity is determined based on the configuration parameters of the network device; and the third quantity is determined based on the configuration parameters of the network device.

[0092] In some embodiments of this application, the configuration parameters can be the first parameters, the first quantity can be the first number of bits, and the second quantity can be the first number of coding blocks.

[0131] In some embodiments of this application, when the segmentation parameters of the above N sub-units include the maximum number of coded blocks included in the sub-units, it indicates that the number of coded blocks included in each of the above N sub-units can be less than or equal to the maximum number of coded blocks included in the sub-units.

[0132] In some embodiments of this application, the proportion information of the amount of data contained in the sub-unit includes at least one of the following: the ratio between the number of bits contained in the sub-unit and the first number of bits; the ratio between the number of coded blocks contained in the sub-unit and the first number of coded blocks; the ratio between the number of bits in the sub-unit; and the ratio between the number of coded blocks in the sub-unit.

The specific proportion can be determined according to actual needs, and this embodiment does not impose any restrictions here.

[0134] For example, if the ratio information of the amount of data contained in the above sub-unit is the ratio between the number of bits contained in each sub-unit and the number of first bits, and this ratio information is... This indicates that the first data unit includes two sub-units. One sub-unit contains bits in a ratio of 1 / 3 to the number of bits in the first sub-unit, and the other sub-unit contains bits in a ratio of 2 / 3 to the number of bits in the first sub-unit.

[0135] For example, if the ratio information of the amount of data contained in the above sub-unit is the ratio between the number of coded blocks contained in each sub-unit and the number of first coded blocks, and this ratio information is... This indicates that the first data unit includes two sub-units. One sub-unit contains a coded block count that is half the number of the first coded blocks, and the other sub-unit contains a coded block count that is half the number of the first coded blocks.

[0136] For example, if the ratio information of the amount of data contained in the above sub-unit is the ratio of the number of bits in N sub-units, and the ratio information is {1,2}, then it indicates that the first data unit includes 2 sub-units, and the ratio of the number of bits in the 2 sub-units is 1:2.

[0137] For example, if the ratio information of the amount of data contained in the above sub-unit is the ratio between the number of coded blocks of the N sub-units, and the ratio information is {1,1}, then it indicates that the first data unit includes 2 sub-units, and the ratio between the number of coded blocks of the 2 sub-units is 1:1.

The specific ratio can be determined according to actual needs, and this embodiment does not impose any restrictions here.

[0140] For example, if the resource quantity ratio information of the above sub-units is the ratio between the resource quantity occupied by each sub-unit and the first resource quantity, and this ratio information is... This indicates that the first data unit includes two sub-units. One sub-unit occupies resources in a ratio of 2 / 5 to the total first resource quantity, while the other sub-unit occupies resources in a ratio of 3 / 5 to the total first resource quantity.

[0141] For example, if the ratio of the resources occupied by the above sub-units is the ratio of the resources occupied by N sub-units, and the ratio is {2,3}, then it indicates that the first data unit includes 2 sub-units, and the ratio of the resources occupied by the 2 sub-units is 2:3.

[0142] In some embodiments of this application, the location information of the resources occupied by the sub-unit may include at least one of the following: the starting location information of the resources occupied by the sub-unit, and the ending location information of the resources occupied by the sub-unit.

[0143] In some embodiments of this application, the terminal device can map service data with different performance requirements to the above N sub-units based on the segmentation parameters of the above N sub-units, and send them after encoding.

[0144] In some embodiments of this application, the data volume information of the other sub-units among the above N sub-units, excluding at least one of the above sub-units, can be determined based on the first parameter configured by the network device for the terminal device and the data volume information of at least one of the above N sub-units.

[0145] In some embodiments of this application, the data volume information of the at least one sub-unit can be the data volume information of N-1 sub-units out of N sub-units, or it can be the data volume information of the N sub-units.

[0146] In some embodiments of this application, the data volume information of the at least one subunit includes at least one of the following: the number of bits contained in one subunit; the number of coded blocks contained in one subunit; proportional information related to the number of bits contained in one subunit; and proportional information related to the number of coded blocks contained in one subunit.

[0147] For example, if the data volume information of at least one sub-unit is the number of bits contained in one of the at least one sub-units, and the number of bits contained in one of the at least one sub-units is {333, 666}, then it indicates that the first data unit includes two sub-units. One sub-unit contains 333 bits, and the other sub-unit contains 666 bits.

[0148] For example, if the data volume information of at least one sub-unit is the number of coded blocks contained in one of the at least one sub-units, and the number of coded blocks contained in one of the at least one sub-units is {33, 66}, then it indicates that the first data unit includes two sub-units. One sub-unit contains 33 coded blocks, and the other sub-unit contains 66 coded blocks.

[0149] In some embodiments of this application, the ratio information related to the number of bits contained in one of the at least one subunits includes at least one of the following: the ratio between the number of bits contained in one of the at least one subunits and the first number of bits; the ratio between the number of bits in the subunits of the at least one subunit.

[0150] For example, if the data volume information of at least one sub-unit is the ratio between the number of bits contained in one of the at least one sub-units and the number of first bits, and this data volume information is... This indicates that the first data unit includes two sub-units. One sub-unit contains bits in a ratio of 1 / 3 to the number of bits in the first sub-unit, and the other sub-unit contains bits in a ratio of 2 / 3 to the number of bits in the first sub-unit.

[0151] For example, if the data volume information of at least one sub-unit is the ratio between the number of bits in the sub-units of the at least one sub-unit, and the data volume information is {1,2}, then it indicates that the first data unit includes 2 sub-units, and the ratio between the number of bits contained in the 2 sub-units is 1:2.

[0152] In some embodiments of this application, the ratio information related to the number of coded blocks contained in one of the at least one subunits includes at least one of the following: the ratio between the number of coded blocks contained in one of the at least one subunits and the number of the first coded blocks; the ratio between the number of coded blocks in the subunits of the at least one subunit.

[0153] For example, if the data volume information of at least one sub-unit is the ratio between the number of coded blocks contained in one of the at least one sub-units and the number of the first coded blocks, and the data volume information is... This indicates that the first data unit includes three sub-units. Specifically, the ratio of the number of coded blocks in one sub-unit to the number of the first coded blocks is 1 / 3, and the ratio of the number of coded blocks in the second sub-unit to the number of the first coded blocks is also 1 / 3.

[0154] For example, if the data volume information of at least one sub-unit is the ratio between the number of coded blocks of the sub-units in the at least one sub-unit, and the data volume information is {1,1,1}, then it indicates that the first data unit includes 3 sub-units, and the ratio between the number of coded blocks contained in the 3 sub-units is 1:1:1.

[0155] In some embodiments of this application, the resource information of the other sub-units among the N sub-units, excluding at least one of the above-mentioned sub-units, can be determined based on the second parameter configured by the network device for the terminal device and the resource information of at least one of the N sub-units.

[0156] In some embodiments of this application, the resource information of the at least one sub-unit can be the resource information of N-1 sub-units out of N sub-units, or it can be the resource information of the N sub-units.

[0157] In some embodiments of this application, the resource information of the at least one sub-unit indicates at least one of the following: the type of resource occupied by the at least one sub-unit; the location of the resource occupied by the at least one sub-unit; the quantity of resources occupied by the at least one sub-unit; and the proportion related to the quantity of resources occupied by the at least one sub-unit.

[0158] It should be noted that the resource information of the at least one sub-unit can directly indicate at least one of the following: the type of resource occupied by a sub-unit in the at least one sub-unit; the location of the resource occupied by a sub-unit in the at least one sub-unit; the quantity of resources occupied by a sub-unit in the at least one sub-unit; and the proportion related to the quantity of resources occupied by a sub-unit in the at least one sub-unit. The resource information of the at least one sub-unit can also indirectly indicate at least one of the following: the type of resource occupied by a sub-unit in the at least one sub-unit; the location of the resource occupied by a sub-unit in the at least one sub-unit; the quantity of resources occupied by a sub-unit in the at least one sub-unit; and the proportion related to the quantity of resources occupied by a sub-unit in the at least one sub-unit.

[0159] In some embodiments of this application, the above-mentioned resource types include, but are not limited to, at least one of the following: time-domain resources, frequency-domain resources, and RE.

[0160] In some embodiments of this application, the resource location may include at least one of the following: resource start location; resource end location; duration.

[0161] For example, if the resource information of at least one sub-unit is the resource type occupied by one of the at least one sub-units, and the resource type occupied by one of the at least one sub-units is {time domain resource, time domain resource}, then it indicates that the first data unit includes two sub-units, and the resource type occupied by both sub-units is time domain resource.

[0162] For example, if the resource information of at least one sub-unit is the resource location occupied by one of the at least one sub-units, and the resource location occupied by one of the at least one sub-units is {0 / 24, 25 / 49}, then it indicates that the first data unit includes two sub-units. Specifically, one of the two sub-units occupies resource locations from resource 0 to resource 24, and the other sub-unit occupies resource locations from resource 24 to resource 49.

[0163] For example, if the resource information of at least one sub-unit is the amount of resources occupied by one of the at least one sub-units, and the amount of resources occupied by one of the at least one sub-units is {25, 25}, then it indicates that the first data unit includes two sub-units. Both sub-units occupy 25 resources.

[0164] For example, if the resource information of at least one sub-unit is the starting position of the resources occupied by one of the at least one sub-units and the number of resources occupied by one of the at least one sub-units, and the data volume information of at least one sub-unit is {0 / 25, 25 / 25}, then it indicates that the first data unit includes two sub-units. Specifically, the starting position of the resources occupied by one of the two sub-units is resource 0, and the number of resources occupied is 25; the starting position of the resources occupied by the other sub-unit is resource 25, and the number of resources occupied is also 25.

[0165] For example, if the resource information of at least one sub-unit is the end position of the resource occupied by one of the at least one sub-units and the number of resources occupied by one of the at least one sub-units, and the resource information of at least one sub-unit is {24 / 25, 49 / 25}, then it indicates that the first data unit includes two sub-units. Specifically, one of the two sub-units occupies the 24th resource at its end position and occupies 25 resources; the other sub-unit occupies the 49th resource at its end position and occupies 25 resources.

[0166] For example, if the resource information of at least one sub-unit is the starting position occupied by one of the at least one sub-units and the resource length occupied by one of the at least one sub-units, and the resource information of at least one sub-unit is {0 / 25, 25 / 25}, then it indicates that the first data unit includes two sub-units. Specifically, one of the two sub-units occupies the resource starting position of resource 0, and the duration of the occupied resource is 25; the other sub-unit occupies the resource starting position of resource 25, and the duration of the occupied resource is 25.

[0167] In some embodiments of this application, the ratio related to the amount of resources occupied by the at least one sub-unit includes at least one of the following: the ratio between the amount of resources occupied by one sub-unit of the at least one sub-unit and the total amount of resources occupied by the first data unit; the ratio between the amount of resources occupied by the sub-units of the at least one sub-unit.

[0168] For example, if the resource information of the above at least one sub-unit is the ratio between the amount of resources occupied by one of the above at least one sub-units and the first amount of resources, and the data volume information is... This indicates that the first data unit includes three sub-units. The ratio of the resources occupied by the first sub-unit to the total resources is 2 / 5, and the ratio of the resources occupied by the second sub-unit to the total resources is also 2 / 5.

[0169] For example, if the resource information of the above at least one sub-unit is the ratio between the number of resources occupied by the sub-units in the above at least one sub-unit, and the resource information is {2,2,1}, then it indicates that the first data unit includes 3 sub-units, and the ratio between the number of resources occupied by the 3 sub-units is 2:2:1.

[0170] In this way, the terminal device sends the first information to indicate the segmentation parameters of the N sub-units in the first data unit to the receiving end, so that the receiving end can accurately and efficiently receive the service data with different performance requirements contained in the N sub-units based on the segmentation parameters, thereby improving the transmission efficiency of services with different performance requirements.

[0171] In some embodiments of this application, the first information mentioned above includes N sub-information, and one sub-information is used to indicate the relevant information of one of the N sub-units.

[0172] In some embodiments of this application, the aforementioned sub-information may include at least one of the following: the segmentation method of the aforementioned sub-unit; the segmentation parameters of the aforementioned sub-unit; the data volume information of the aforementioned sub-unit; and the resource information of the aforementioned sub-unit.

[0173] It should be noted that the explanation of the division method of the above-mentioned one sub-unit can be found in the relevant description of the division method of the above-mentioned N sub-units. To avoid repetition, this embodiment will not repeat it here.

[0174] It should be noted that the explanation of the segmentation parameters of the above-mentioned sub-unit can be found in the relevant description of the segmentation parameters of the above-mentioned N sub-units. To avoid repetition, this embodiment will not repeat it here.

[0176] It should be noted that the explanation of the resource information of one of the above sub-units can be found in the relevant description of the resource information of at least one of the above N sub-units. To avoid repetition, this embodiment will not repeat it here.

[0177] In this way, by sending first information including N sub-information, the terminal device can indicate to the receiving end that the first data unit carried by the first channel contains N sub-units of service data with different performance requirements. This enables the receiving end to accurately and efficiently receive the service data with different performance requirements contained in the N sub-units based on the first information, thereby improving the transmission efficiency of services with different performance requirements.

[0178] In some embodiments of this application, the first information includes N-1 sub-information, which are used to indicate the relevant information of the N-1 sub-units among the N sub-units.

[0179] In some embodiments of this application, the relevant information of one subunit other than the N-1 subunits is determined based on the relevant information of the N-1 subunits.

[0180] In some embodiments of this application, the aforementioned N-1 sub-units satisfy any of the following: the aforementioned N-1 sub-units are the first N-1 sub-units among the aforementioned N sub-units; the aforementioned N-1 sub-units are the last N-1 sub-units among the aforementioned N sub-units; one sub-unit among the aforementioned N sub-units other than the aforementioned N-1 sub-units is the first sub-unit among the aforementioned N sub-units; and one sub-unit among the aforementioned N sub-units other than the aforementioned N-1 sub-units is the last sub-unit among the aforementioned N sub-units.

[0181] In some embodiments of this application, the aforementioned sub-information may include at least one of the following: the segmentation method of the aforementioned first sub-unit; the segmentation parameters of the aforementioned first sub-unit; the data volume information of the aforementioned first sub-unit; and the resource information of the aforementioned first sub-unit.

[0182] It should be noted that the description of the division method of the first sub-unit can be found in the relevant description of the division method of the N sub-units. To avoid repetition, this embodiment will not repeat it here.

[0183] It should be noted that the description of the segmentation parameters of the first sub-unit can be found in the description of the segmentation parameters of the N sub-units. To avoid repetition, this embodiment will not repeat the description here.

[0184] It should be noted that the description of the data volume information of the first sub-unit mentioned above can be found in the relevant description of the data volume information of at least one of the N sub-units mentioned above. To avoid repetition, this embodiment will not repeat it here.

[0185] It should be noted that the explanation of the resource information of the first subunit mentioned above can be found in the relevant description of the resource information of at least one of the N subunits mentioned above. To avoid repetition, this embodiment will not repeat it here.

[0186] In some embodiments of this application, the order in which some or all of the sub-information in the first information is arranged is the same as the order in which the sub-units indicated by the some or all of the sub-information are arranged in the first data unit.

[0187] In some embodiments of this application, the above-mentioned arrangement order can be from low to high priority, or from high to low priority. The arrangement order can be a pre-set arrangement order based on attributes. The specific arrangement order can be determined according to actual needs, and this embodiment does not impose any restrictions here.

[0188] In some embodiments of this application, the above attributes are used to distinguish between multiple different types of data.

[0189] In some embodiments of this application, the aforementioned attributes may include service identifiers, service performance indicators, service characteristics, service types, and service quality of service (QoS), etc. The specific attributes can be determined according to actual needs, and this embodiment does not impose any limitations. Their function is to distinguish between various types of data.

[0190] In this way, by sending first information including N-1 sub-information, the terminal device can indicate to the receiving end that the first data unit carried by the first channel contains N sub-units of service data with different performance requirements. This enables the receiving end to accurately and efficiently receive the service data with different performance requirements contained in the N sub-units based on the first information, thereby improving the transmission efficiency of services with different performance requirements.

[0191] In some embodiments of this application, one of the above N sub-units has at least one of the following features: independent CRC; independent encoding; independent feedback response information; a set containing independent encoding units.

[0192] In some embodiments of this application, a sub-unit has the characteristic of an independent CRC, indicating that the terminal device can add independent CRC information in the sub-unit.

[0193] In some embodiments of this application, a sub-unit has the feature of independent encoding, indicating that the terminal device can independently encode the sub-unit.

[0194] In some embodiments of this application, a subunit has the feature of independent feedback response information, indicating that the terminal device can independently receive the feedback response information of the subunit.

[0195] In some embodiments of this application, a subunit has the characteristic of containing a set of independent coding units, indicating that the subunit does not share the set of coding units with other subunits, for example, a subunit does not share a set of CBs with other subunits.

[0196] Thus, if one of the N sub-units has at least one of the following characteristics: independent CRC, independent encoding, independent feedback response information, and a set containing independent encoding units, the reliability of the sub-unit during transmission can be improved.

[0197] In some embodiments of this application, the data concatenation of the above-mentioned N sub-units is performed after the data of the above-mentioned N sub-units has been channel-coded.

[0198] In some embodiments of this application, the phrase "the concatenation of data of N sub-units is performed after the data of the N sub-units has undergone channel coding" can be understood as follows: after the terminal device performs channel coding on the data of the N sub-units, it may not immediately concatenate the data of the N sub-units. That is, the terminal device can perform other operations after performing channel coding on the data of the N sub-units before it can concatenate the data of the N sub-units.

[0199] In this way, the terminal device can independently transmit the data of N sub-units through the first channel by channel coding and concatenating the data of N sub-units.

[0200] In some embodiments of this application, the data concatenation of the above-mentioned N sub-units is performed after the data of the above-mentioned N sub-units has undergone layer mapping.

[0201] In some embodiments of this application, the phrase "the data concatenation of the N sub-units is performed after the data of the N sub-units has undergone layer mapping" can be understood as follows: after the terminal device performs layer mapping on the data of the N sub-units, it may not immediately concatenate the data of the N sub-units. That is, the terminal device needs to perform layer mapping on the data of the N sub-units before performing other operations, and only then can it concatenate the data of the N sub-units.

[0202] In this way, by mapping the data of N sub-units in the layer and then concatenating the data of the N sub-units, the terminal device can independently transmit the data of the N sub-units on the first channel.

[0203] In the communication method provided in this application embodiment, the terminal device sends first information, which is used to indicate the relevant information of N sub-units included in the first data unit, where N is an integer greater than 1. In this solution, the terminal device sends the first information to indicate to the receiving end the relevant information of N sub-units of service data with different performance requirements included in the first data unit, so that the receiving end can accurately and efficiently receive the service data with different performance requirements contained in the N sub-units based on the first information, thereby improving the transmission efficiency of services with different performance requirements.

[0205] Step 301: The network device receives the first information from the terminal device.

[0206] In some embodiments of this application, the first information is used to indicate the relevant information of the N sub-units included in the first data unit, where N is an integer greater than 1.

[0207] In some embodiments of this application, the first information and the first data unit can be transmitted through the first channel; wherein the first information is encoded independently of the first data unit.

[0208] It should be noted that the explanation of the transmission of the first information and the first data unit through the first channel can be found in the relevant description in step 201 above. To avoid repetition, this embodiment will not repeat the description here.

[0209] In some embodiments of this application, the first data unit is a codeword, and the sub-unit is at least one of the following: TB, CB, CBG.

[0210] In some embodiments of this application, the first data unit is TB, and the sub-unit is at least one of the following: CB, CBG.

[0211] In some embodiments of this application, the first data unit is a Hybrid Automatic Repeat Request (HARQ) process, and the sub-unit is at least one of the following: HARQ sub-process, TB, CB, CBG.

[0212] In some embodiments of this application, the first data unit is a data channel, and the sub-unit is at least one of the following: sub-data channel, HARQ sub-process, TB, CB, CBG.

[0213] It should be noted that the explanation of the first data unit and the above-mentioned sub-units can be found in the relevant description in step 201 above. To avoid repetition, this embodiment will not repeat it here.

[0214] In some embodiments of this application, the data volume of the above N sub-units is related to the first parameter configured by the network device for the terminal device.

[0248] In some embodiments of this application, the resource quantity occupied by one of the above N sub-units is... or Among them, R total This indicates the quantity of the first resource mentioned above.

[0249] In some embodiments of this application, the division of the above-mentioned N sub-units includes any one of the following: uniform division; non-uniform division; division according to a preset ratio; division according to priority; division according to attribute; no division.

[0250] In some embodiments of this application, when the above-mentioned N sub-units are divided in a uniform manner, the network device can divide the first data unit into N sub-units in a uniform manner. Each of the N sub-units has the same bit percentage in the first data unit (i.e., the number of bits in each sub-unit is the same), or each of the N sub-units has the same percentage of coded blocks in the first data unit (i.e., the number of coded blocks contained in each sub-unit is the same).

[0251] In some embodiments of this application, when the above-mentioned N sub-units are divided in a non-uniform manner, the network device can divide the first data unit into N sub-units according to the non-uniform division method. Some or all of the N sub-units obtained from the division have different proportions in the first data unit. For example, some or all of the N sub-units obtained from the division have different bit proportions in the first data unit (i.e., some or all of the sub-units have different bit counts), or some or all of the N sub-units obtained from the division have different proportions of coded blocks in the first data unit (i.e., some or all of the sub-units contain different numbers of coded blocks).

[0252] In some embodiments of this application, when the above-mentioned N sub-units are divided according to a preset ratio, the network device can divide the first data unit into N sub-units according to the preset ratio. The bit percentage of the N sub-units in the first data unit conforms to the preset ratio, or, the percentage of the number of coded blocks of some or all of the above-mentioned N sub-units in the first data unit conforms to the preset ratio.

[0253] In some embodiments of this application, when the above-mentioned N sub-units are divided by priority, the network device can divide the first data unit into N sub-units according to the service priority. For example, the network device can divide the first data unit into N sub-units according to the service priority. If, among the N sub-units obtained, the sub-unit containing services with higher service priority has a larger proportion in the first data unit, or if, among the N sub-units obtained, the sub-unit containing services with lower service priority has a smaller proportion in the first data unit.

[0254] In some embodiments of this application, when the above-mentioned N sub-units are divided according to service attributes, the network device can divide the first data unit into N sub-units according to the service attribute division method. For example, among the N sub-units obtained by division, the sub-unit containing services with specific service attributes accounts for a large proportion of the first data unit.

[0255] In some embodiments of this application, the terminal device divides the first data unit into N sub-units based on the above-mentioned N sub-units division method and performs decoding.

[0256] In this way, by receiving the aforementioned first information, the network device can accurately and efficiently receive service data with different performance requirements contained in N sub-units based on the segmentation method indicated by the first information, thereby improving the transmission efficiency of services with different performance requirements.

[0257] In some embodiments of this application, the segmentation parameters of the above-mentioned N sub-units include at least one of the following: minimum data volume contained in the sub-unit; maximum data volume contained in the sub-unit; maximum number of sub-units; minimum number of sub-units; minimum number of coding blocks contained in the sub-unit; maximum number of coding blocks contained in the sub-unit; priority of the sub-unit; attributes of the sub-unit; proportion information of the data volume contained in the sub-unit; proportion information of the amount of resources occupied by the sub-unit; location information of the resources occupied by the sub-unit.

[0258] In some embodiments of this application, if the segmentation parameters of the above N sub-units include the minimum amount of data contained in the sub-unit, it indicates that the amount of data contained in each of the above N sub-units is greater than or equal to the minimum amount of data contained in the sub-unit.

[0259] In some embodiments of this application, if the segmentation parameters of the above N sub-units include the maximum amount of data contained in the sub-unit, it indicates that the amount of data contained in each of the above N sub-units is less than or equal to the maximum amount of data contained in the sub-unit.

[0260] In some embodiments of this application, when the segmentation parameters of the above N sub-units include the maximum number of sub-units, it indicates that the value of N is less than or equal to the maximum number of sub-units.

[0261] In some embodiments of this application, when the division parameters of the above N sub-units include the minimum number of sub-units, it indicates that the value of N is greater than or equal to the minimum number of sub-units.

[0262] In some embodiments of this application, when the segmentation parameters of the above N sub-units include the minimum number of coded blocks included in the sub-units, it indicates that the number of coded blocks included in each of the above N sub-units can be greater than or equal to the minimum number of coded blocks included in the sub-units.

[0263] In some embodiments of this application, when the segmentation parameters of the above N sub-units include the maximum number of coded blocks included in the sub-units, it indicates that the number of coded blocks included in each of the above N sub-units can be less than or equal to the maximum number of coded blocks included in the sub-units.

[0264] For example, if the first bit quantity is 1000 bits, and the segmentation parameters of the above N sub-units include: the minimum data quantity of the sub-unit is 50 bits, the maximum data quantity of the sub-unit is 100 bits, the maximum number of sub-units is 10, and the minimum number of sub-units is 3, then the network device can divide the first data unit into 5 sub-units based on the first bit quantity of 1000 bits and the segmentation parameters, and each of the 5 sub-units can contain 200 bits of data.

[0265] For example, if the number of the first coding blocks is 50, and the segmentation parameters of the above N sub-units include: the maximum number of sub-units is 10, the minimum number of sub-units is 3, the minimum number of coding blocks included in the sub-unit is 5, and the maximum number of coding blocks included in the sub-unit is 15, then the network device can divide the first data unit into 5 sub-units based on the number of the first coding blocks of 50 and the segmentation parameters, and the number of coding blocks included in each of the 5 sub-units can be 10.

[0266] In some embodiments of this application, the proportion information of the amount of data contained in the sub-unit includes at least one of the following: the ratio between the number of bits contained in the sub-unit and the first number of bits; the ratio between the number of coded blocks contained in the sub-unit and the first number of coded blocks; the ratio between the number of bits in the sub-unit; and the ratio between the number of coded blocks in the sub-unit.

[0267] It should be noted that the proportion of data contained in the above sub-unit can be the proportion of data contained in N sub-units, the proportion of data contained in N-1 sub-units out of N sub-units, or the proportion of data contained in at least one sub-unit out of N sub-units. The specific proportion can be determined according to actual needs, and this embodiment does not impose any restrictions here.

[0268] For example, if the number of the first bit is 1000, the segmentation parameter of the above N sub-units is the proportion of the data contained in the above sub-units. Furthermore, this ratio information, showing the proportion of bits contained in each sub-unit to the total number of bits in the first data unit, indicates that the first data unit comprises two sub-units. One sub-unit contains bits in a ratio of 1 / 3 to the total number of bits in the first data unit, and the other sub-unit contains bits in a ratio of 2 / 3 to the total number of bits in the first data unit. Therefore, the network device can divide the first data unit into two sub-units. Each sub-unit contains a number of bits... or That is, one subunit contains 333 or 334 bits; the other subunit contains 100 bits. or That is, the other sub-unit contains 666 or 667 bits.

[0269] For example, if the number of the first coding block is 100, the segmentation parameters of the above N sub-units are the proportion of the data contained in the above sub-units. Furthermore, this ratio information indicates that the first data unit comprises two sub-units, representing the ratio between the number of coded blocks in each sub-unit and the number of first coded blocks. One sub-unit contains coded blocks in a ratio of 1 / 2 to the number of first coded blocks, and the other sub-unit also contains coded blocks in a ratio of 1 / 2 to the number of first coded blocks. Therefore, the network device can divide the first data unit into two sub-units. Each sub-unit contains a number of coded blocks... or That is, one subunit contains 50 coded blocks; the other subunit contains 10 coded blocks. or That is, the number of coded blocks contained in the other subunit is 50.

[0270] For example, if the first data unit has 1000 bits, and the partitioning parameter of the N sub-units is the ratio of the data volume contained in each sub-unit to the data volume contained in the sub-unit, which is the ratio of the number of bits in the N sub-units, it indicates that the first data unit includes 2 sub-units, and the ratio of the number of bits in the 2 sub-units is 1:2. Then the network device can partition the first data unit into 2 sub-units. Each sub-unit contains 1000 bits. or That is, one sub-unit contains 333 or 334 bits; the other sub-unit contains 100 bits. or or or That is, the other subunit contains 666, 667, or 668 bits.

[0271] For example, if the network device has 100 first coded blocks, and the segmentation parameter for the aforementioned N sub-units is the ratio of the data volume contained in each sub-unit to the data volume of the sub-units, which is {1,1}, and this ratio is the ratio between the number of coded blocks in the aforementioned N sub-units, indicating that the first data unit includes 2 sub-units and the ratio of the number of coded blocks in the 2 sub-units is 1:1, then the network device can segment the first data unit into 2 sub-units. Each sub-unit contains a number of coded blocks. or That is, one subunit contains 50 coded blocks; the other subunit contains 10 coded blocks. or That is, the number of coded blocks contained in the other subunit is 50.

[0272] In some embodiments of this application, the proportion information of the amount of resources occupied by the sub-unit may include at least one of the following: the ratio between the amount of resources occupied by the sub-unit and the first amount of resources; the ratio between the amounts of resources occupied by the sub-units.

[0273] It should be noted that the resource ratio information of the above-mentioned sub-units can be the resource ratio information of N sub-units, the resource ratio information of N-1 sub-units out of N sub-units, or the resource ratio information of at least one sub-unit out of N sub-units. The specific ratio can be determined according to actual needs, and this embodiment does not impose any restrictions here.

[0274] For example, if the first resource quantity is 50, the segmentation parameter of the above N sub-units is the proportion of the resource quantity occupied by the above sub-units. Furthermore, this ratio information represents the proportion between the number of coded blocks in the aforementioned N sub-units, indicating that the first data unit includes two sub-units. Specifically, the ratio of the resource quantity occupied by one sub-unit to the total first resource quantity is 2 / 5, and the ratio of the resource quantity occupied by the other sub-unit to the total first resource quantity is 3 / 5. Therefore, the network device can divide the first data unit into two sub-units. The resource quantity occupied by one sub-unit is... or That is, one sub-unit occupies 20 resources; the other sub-unit occupies 10 resources. or That is, the other sub-unit occupies 30 resources.

[0275] For example, if the first resource quantity is 50, and the partitioning parameter of the aforementioned N sub-units is the ratio of the resource quantity occupied by each sub-unit to the resource quantity occupied by the N sub-units, which is {2,3}, and this ratio is the ratio of the resource quantity occupied by each sub-unit to the resource quantity occupied by the N sub-units, it indicates that the first data unit includes 2 sub-units, and the ratio of the resource quantity occupied by the 2 sub-units is 2:3. Then the network device can partition the first data unit into 2 sub-units. Each sub-unit occupies a resource quantity of... or or or That is, one sub-unit contains 20 resources; the other sub-unit occupies 100 resources. or or or That is, the other sub-unit occupies 30 resources.

[0276] In some embodiments of this application, the data volume information of the at least one subunit includes at least one of the following: the number of bits contained in one subunit; the number of coded blocks contained in one subunit; proportional information related to the number of bits contained in one subunit; and proportional information related to the number of coded blocks contained in one subunit.

[0277] For example, if the data volume information of at least one sub-unit is the number of bits contained in one of the at least one sub-units, and the number of bits contained in one of the at least one sub-units is {333, 666}, then the network device can determine that the first data unit includes two sub-units based on the data volume information of the at least one sub-unit. Specifically, one sub-unit contains 333 bits, and the other sub-unit contains 666 bits.

[0278] For example, if the data volume information of at least one sub-unit is the number of coded blocks contained in one of the at least one sub-units, and the number of coded blocks contained in one of the at least one sub-units is {33, 66}, then the network device can determine that the first data unit includes two sub-units based on the data volume information of the at least one sub-unit. Specifically, one sub-unit contains 33 coded blocks, and the other sub-unit contains 66 coded blocks.

[0279] In some embodiments of this application, the ratio information related to the number of bits contained in one of the at least one subunits includes at least one of the following: the ratio between the number of bits contained in one of the at least one subunits and the first number of bits; the ratio between the number of bits in the subunits of the at least one subunit.

[0280] In some embodiments of this application, the network device may divide the first data unit based on the ratio between the first number of bits and the number of bits contained in one of the at least one sub-units of the first data unit to the total number of bits of the first data unit, and determine the number of bits contained in one of the at least one sub-units obtained by dividing the first data unit.

[0281] For example, if the number of the first bit is 1000, the ratio between the number of bits contained in one of the at least one sub-units and the number of the first bit is: This indicates that the first data unit comprises two sub-units. One sub-unit contains one-third the number of bits compared to the first data unit, and the other sub-unit contains two-thirds the number of bits compared to the first data unit. Therefore, the network device can divide the first data unit into two sub-units. One sub-unit contains [number of bits]. or That is, one subunit contains 333 or 334 bits; the other subunit contains 100 bits. or That is, the other sub-unit contains 666 or 667 bits.

[0282] In some embodiments of this application, the network device may divide the first data unit based on the ratio between the first number of bits and the number of bits in the sub-unit of the at least one sub-unit, and determine the number of coded blocks contained in one of the sub-units obtained by dividing the first data unit.

[0283] For example, if the first data unit contains 1000 bits, and the ratio of the number of bits in each sub-unit is {1,2}, this indicates that the first data unit includes two sub-units, and the ratio of the number of bits in the two sub-units is 1:2. Therefore, the network device can divide the first data unit into two sub-units. Each sub-unit contains 1000 bits. or That is, one subunit contains 333 or 334 bits; the other subunit contains 100 bits. or or or That is, the other subunit contains 666, 667, or 668 bits.

[0284] In some embodiments of this application, the ratio information related to the number of coded blocks contained in one of the at least one subunits includes at least one of the following: the ratio between the number of coded blocks contained in one of the at least one subunits and the number of the first coded blocks; the ratio between the number of coded blocks in the subunits of the at least one subunit.

[0285] In some embodiments of this application, the network device may segment the first data unit based on the ratio between the number of first coding blocks and the number of coding blocks contained in one of the at least one sub-units obtained by segmenting the first data unit, and determine the number of coding blocks contained in one of the at least one sub-units obtained by segmenting the first data unit.

[0286] For example, if the number of the first coded blocks is 100, the ratio between the number of coded blocks contained in one of the at least one sub-units and the number of the first coded blocks is: This indicates that the first data unit comprises three sub-units. The ratio of the number of coded blocks in the first sub-unit to the total number of coded blocks in the first data unit is 1 / 3, and the ratio of the number of coded blocks in the second sub-unit to the total number of coded blocks in the first data unit is also 1 / 3. Therefore, the network device can divide the first data unit into three sub-units. The number of coded blocks in the first sub-unit is... or That is, the first subunit contains 33 or 34 coded blocks; the second subunit contains 33 or 34 coded blocks. or That is, the second subunit contains 33 or 34 coded blocks. Further, the network device can determine that the ratio of the number of coded blocks in the third subunit to the number of the first coded blocks is 1 / 3, based on the ratio of the number of coded blocks in the first subunit to the number of first coded blocks, and the ratio of the number of coded blocks in the second subunit to the number of first coded blocks is also 1 / 3. Therefore, the network device can determine that the third subunit contains a certain number of coded blocks. or That is, the number of coded blocks contained in each third subunit is 33 or 34.

[0287] In some embodiments of this application, the network device may segment the first data unit based on the ratio between the number of first coding blocks and the number of coding blocks in the subunit of the at least one subunit obtained by segmenting the first data unit, and determine the number of coding blocks contained in one of the subunits.

[0288] For example, if the number of first coded blocks is 100, and the ratio of the number of coded blocks in each sub-unit of the aforementioned at least one sub-unit is {1,1,1}, then this indicates that the first data unit includes 3 sub-units, and the ratio of the number of coded blocks contained in the 3 sub-units is 1:1:1. The network device can then divide the first data unit into 3 sub-units. The first sub-unit contains the following number of coded blocks: or That is, the first subunit contains 33 or 34 coded blocks; the second subunit contains 33 or 34 coded blocks. or That is, the second subunit contains 33 or 34 coded blocks. The third subunit contains 33 or 34 coded blocks. or That is, the third subunit contains 33 or 34 coded blocks.

[0289] In some embodiments of this application, the resource information of at least one sub-unit indicates at least one of the following: the type of resource occupied by one of the at least one sub-units; the quantity of resources occupied by one of the at least one sub-units; the location of the resources occupied by one of the at least one sub-units; and the proportion related to the quantity of resources occupied by one of the at least one sub-units.

[0290] In some embodiments of this application, the above-mentioned resource types include, but are not limited to, at least one of the following: time-domain resources, frequency-domain resources, and RE.

[0291] In some embodiments of this application, the resource location may include at least one of the following: resource start location; resource end location; duration.

[0292] In some embodiments of this application,

[0293] For example, if the resource information of at least one sub-unit is the resource type occupied by one of the at least one sub-units, and the resource type occupied by one of the at least one sub-units is {time domain resource, time domain resource}, then the network device can determine that the first data unit includes two sub-units based on the data volume information of the at least one sub-unit, and the resource type occupied by the two sub-units is time domain resource.

[0294] For example, if the resource information of at least one sub-unit is the resource location occupied by one of the at least one sub-units, and the resource location occupied by one of the at least one sub-units is {0 / 24, 25 / 49}, then the network device can determine that the first data unit includes two sub-units based on the resource information of the at least one sub-unit. Specifically, one of the two sub-units occupies resource locations from resource 0 to resource 24, and the other sub-unit occupies resource locations from resource 24 to resource 49.

[0295] For example, if the resource information of at least one sub-unit is the amount of resources occupied by one of the at least one sub-units, and the amount of resources occupied by one of the at least one sub-units is {25, 25}, then the network device can determine that the first data unit includes two sub-units based on the data volume information of the at least one sub-unit. Both sub-units occupy 25 resources.

[0296] For example, if the resource information of at least one sub-unit consists of the starting position of the resource occupied by one of the at least one sub-units and the quantity of resources occupied by one of the at least one sub-units, and the data volume information of at least one sub-unit is {0 / 25, 25 / 25}, then the network device can determine that the first data unit includes two sub-units based on the resource information of the at least one sub-unit. Specifically, the starting position of the resource occupied by one of the two sub-units is resource 0, and the quantity of resources occupied is 25; the starting position of the resource occupied by the other sub-unit is resource 25, and the quantity of resources occupied is also 25.

[0297] For example, if the resource information of at least one sub-unit consists of the end position of the resource occupied by one of the at least one sub-units and the number of resources occupied by one of the at least one sub-units, and the resource information of at least one sub-unit is {24 / 25, 49 / 25}, then the network device can determine that the first data unit includes two sub-units based on the resource information of the at least one sub-unit. Specifically, one of the two sub-units occupies the 24th resource at its end position and occupies 25 resources; the other sub-unit occupies the 49th resource at its end position and occupies 25 resources.

[0298] For example, if the resource information of at least one sub-unit consists of the starting position occupied by one of the at least one sub-units and the resource length occupied by one of the at least one sub-units, and the resource information of at least one sub-unit is {0 / 25, 25 / 25}, then the network device can determine that the first data unit includes two sub-units based on the resource information of the at least one sub-unit. Specifically, one of the two sub-units occupies the resource starting position of resource 0, and the duration of the occupied resource is 25; the other sub-unit occupies the resource starting position of resource 25, and the duration of the occupied resource is 25.

[0299] In some embodiments of this application, the ratio related to the amount of resources occupied by the at least one sub-unit includes at least one of the following: the ratio between the amount of resources occupied by one sub-unit in the at least one sub-unit and the first amount of resources; the ratio between the amounts of resources occupied by the sub-units in the at least one sub-unit.

[0300] In some embodiments of this application, the network device may divide the first data unit based on the first resource quantity and the ratio between the resource quantity occupied by one of the at least one sub-units and the first resource quantity, and determine the resource quantity occupied by one of the at least one sub-units obtained from the division of the first data unit.

[0301] For example, if the first resource quantity is 50, the ratio between the resource quantity occupied by one of the at least one sub-units and the first resource quantity is: This indicates that the first data unit comprises three sub-units. The resource allocation ratio between the first sub-unit and the total resource allocation is 2 / 5, and the resource allocation ratio between the second sub-unit and the total resource allocation is also 2 / 5. Therefore, the network device can divide the first data unit into three sub-units. The resource allocation ratio of the first sub-unit is... or That is, the first sub-unit contains 20 resources; the second sub-unit occupies 100 resources. or That is, the second sub-unit occupies 20 resources. Further, based on the ratio of the resources occupied by the first sub-unit to the first resource quantity (2 / 5), and the ratio of the resources occupied by the second sub-unit to the first resource quantity (2 / 5), the network device can determine that the ratio of the resources occupied by the third sub-unit to the first resource quantity is 1 / 5. Therefore, the network device can determine that the third sub-unit occupies... or That is, the resource quantity occupied by the third sub-unit is 10.

[0302] In some embodiments of this application, the network device may divide the first data unit based on the ratio between the first resource quantity and the resource quantity occupied by the sub-unit in at least one sub-unit, and determine the resource quantity occupied by one of the sub-units obtained from the division of the first data unit.

[0303] For example, if the first resource quantity is 50, and the ratio of the resource quantities occupied by the sub-units in the above-mentioned at least one sub-unit is {2,2,1}, then it indicates that the first data unit includes 3 sub-units, and the ratio of the resource quantities occupied by the 3 sub-units is 2:2:1. Therefore, the network device can divide the first data unit into 3 sub-units. The first sub-unit occupies a resource quantity of... or or or That is, the first sub-unit contains 20 resources; the second sub-unit occupies 100 resources. or or or That is, the second sub-unit contains 20 resources; the third sub-unit occupies 100 resources. or That is, the resource quantity occupied by the third sub-unit is 10.
