[0003] However, the number of resource blocks used in determining the transmission block size in related technologies is often greater than the number of resource blocks actually used when transmitting data information between network devices and terminal devices or between terminal devices. As a result, the calculated transmission block size is larger than the transmission block size actually used in the data transmission process, which further leads to a high actual transmission code rate in the data transmission process, and even an inability to carry complete transmission block information in the actual data transmission process, thereby affecting the reliability of data transmission.

[0004] Therefore, how to determine a transport block size that is closer to the transport block size actually used during data transmission is an issue that needs to be addressed urgently.

[0051] First, the relevant technologies involved in the embodiments of this application are introduced:

[0052] (1) Method for determining transport block size

[0053] The transport block size determination in data channels, such as the Physical Downlink Shared Channel (PDSCH) and the Physical Uplink Shared Channel (PUSCH), can be divided into the following three steps. Taking PDSCH as an example, the transport block size determination steps include:

[0054] 1) Determine the number of resource elements (REs) N for PDSCH RE ,include:

[0055] i. Determine the number of resource elements (REs) within a physical resource block (PRB). The calculation formula is:

[0056]

[0057] in, Indicates the number of subcarriers in a resource block (RB); The number of symbols occupied by PDSCH in a time slot; The number of REs occupied by the demodulation reference signal (DMRS) in a PRB; The number of overhead REs configured within a PRB. The number of overhead REs includes the REs occupied by control information such as the synchronization channel, physical broadcast channel (PBCH), physical downlink control channel (PDCCH), and physical uplink control channel (PUCCH).

[0058] ii. Determine the number of REs in PDSCH. The calculation formula is: N RE =min(156,N′ RE )×n PRB .

[0059] Among them, n PRB It is the number of PRBs allocated by the network device to the terminal device.

[0060] 2) Calculate the amount of intermediate information N carried by PDSCH info , the calculation formula is: N info =N RE ×R×Q m ×υ.

[0061] Among them, N RE is the calculated number of REs in PDSCH, R is the code rate of data transmission on PDSCH, Q m It is the modulation order of the data on PDSCH, and υ represents the number of transmission layers of PDSCH.

[0062] 3) Based on the intermediate information N info Determine the Transport Block Size (TB size, TBS):

[0063] i. If N info ≤3824, the transport block size is determined by quantizing the table lookup;

[0064] ii. If N info >3824, the transmission block size is determined by quantitative calculation.

[0065] (2) Uplink subband in downlink symbol / time slot

[0066] In related technologies, data can be sent and received simultaneously on different subbands within the same subframe. This technology, called X-Division Duplex (XDD), is primarily used on network devices. However, the terminal device still supports only sending or receiving data within a subframe.

[0067] Exemplarily, as shown in Figure 1, XDD technology configures the middle subband of the frequency domain resources corresponding to a downlink symbol / time slot as an uplink subband. When a terminal device is configured or instructed to receive data on this downlink symbol / time slot, such as receiving data carried on the PDSCH, the frequency domain resources occupied by the PDSCH overlap with the uplink subband in the frequency domain resources corresponding to the downlink symbol / time slot. Since the network device side is partially using the uplink subband resources to receive uplink data from other terminal devices, the network device side cannot send downlink data to the terminal device on this uplink subband. In other words, the network device side will only send PDSCH to the terminal device on the downlink subbands on both sides of the uplink subband.

[0068] The subband configurations in different symbols / time slots within a subframe may be consistent or different, and this embodiment of the present application does not impose any specific limitation on this.

[0069] (3) Frequency Domain Resource Indication Method

[0070] The frequency domain resource indication methods for PDSCH or PUSCH generally include the following two methods:

[0071] Resource allocation type 0

[0072] Resource allocation is performed according to Type 0. The frequency domain resource information field, that is, the RB allocation information, includes a bitmap to indicate or allocate the resource block group (RBG) of the terminal device. An RBG is a set of continuous PRBs or a set of continuous virtual resource blocks (VRBs). The size of the RBG is determined by a high-level parameter, usually represented by P. The size of the RBG may be different in different bandwidth parts (BWPs) and in different frequency domain resource configurations.

[0073] For a including For an uplink or downlink BWP i of RBs, the total number of RBGs is N RBG The calculation formula is:

[0074] Among them, the number of RBs contained in the first RBG (which can also be understood as the size of the first RBG) is if Then the number of RBs contained in the last RBG is if Then the number of RBs contained in the last RBG is The size of other RBGs is P.

[0075] The bitmap has a total of N RBG Each bit represents an RBG. RBGs are arranged in ascending order of frequency, and the index of BWP starts from the BWP with the lowest frequency. The order of the RBG bitmap is from RBG 0 to RBG N. RBG -1, mapping from the most significant bit (MSB) to the least significant bit (LSB). The RBG allocated to the terminal device and the RBG not allocated to the terminal device are represented by different bit values ​​in the bitmap. When the bit value corresponding to a certain RBG in the bitmap is the first value, it indicates that the RBG is the RBG allocated to the terminal device. When the bit value corresponding to a certain RBG in the bitmap is the second value, it indicates that the RBG is the RBG not allocated to the terminal device. For example, if a certain RBG is allocated to the terminal device, the corresponding bit value in the bitmap is 1. If a certain RBG is not allocated to the terminal device, the corresponding bit value in the bitmap is 0.

[0076] For example, as shown in Figure 2, the network device allocates resources to RBG 0 to RBG 8 according to Type 0, and the bit map is 010001101, which means that the corresponding bits of RBG 1, RBG 5, RBG 6, and RBG 8 in the bit map are 1, and the corresponding bits of other RBGs in the bit map are 0, indicating that RBG 1, RBG 5, RBG 6, and RBG 8 are allocated to the terminal device.

[0077] Resource allocation method 1 (Type 1)

[0078] Resource allocation is performed according to Type 1. In the frequency domain resource information field, that is, the RB allocation information, a continuous VRB set is indicated or allocated to the terminal device. The mapping of VRBs and PRBs in the VRB set is interleaved or non-interleaved. The VRBs in the VRB set are located in the activated BWP.

[0079] For Type 1, the frequency domain resource information field consists of a resource indicator value (RIV), which is based on the starting VRB number RB. start and the allocated RB continuous length L RBS The specific calculation formula is as follows:

[0080] if So

[0081] if So

[0082] in,

[0083] For example, as shown in FIG3 , the network device allocates resources to RB 0 to RB 17 according to Type 1, indicating the starting number of the resource block RB start is 7, the continuous length of the resource block is L RBS If it is 7, it means that RB 7 to RB 14 are allocated to the terminal device.

[0084] However, the number of resource blocks used in the above-mentioned process of determining the transmission block size is often greater than the number of resource blocks actually used when transmitting data information between network devices and terminal devices or between terminal devices, resulting in the calculated transmission block size being larger than the transmission block size actually used in the data transmission process, further resulting in the actual transmission code rate in the data transmission process being higher, and even unable to carry complete transmission block information in the actual data transmission process, thereby affecting the reliability of data transmission.

[0085] Therefore, the present application provides a method for determining the transport block size, which makes the calculated transport block size closer to the transport block size actually used during data transmission, and can make the configured code rate closer to the actual code rate, which is beneficial to improving the reliability of data transmission.

[0098] FIG5 is a flow chart illustrating a method for determining a transport block size provided by some exemplary embodiments of the present application. This method is illustrated by taking the network device 410, terminal device 420, or terminal device 430 shown in FIG4 as an example. The method includes at least some of the following steps:

[0099] Step 510: Determine the transport block size based on the target number of resource blocks.

[0100] The target number of resource blocks is determined based on the first number of resource blocks and the second number of resource blocks.

[0101] The first number of resource blocks is the number of resource blocks allocated to a data channel. The data channel can be a downlink data channel, such as the PDSCH; an uplink data channel, such as the PUSCH; or a sidelink data channel. Optionally, the data channel is a data channel used by a terminal, and the configuration is dynamic or semi-static at the terminal granularity.

[0102] The second number of resource blocks includes the number of resource blocks belonging to the first frequency domain resources in the first number of resource blocks.

[0103] The transmission direction of the frequency domain resources occupied by the data channel is different from the data transmission direction of the first frequency domain resources. For example, if the data channel is a downlink data channel, uplink transmission or sidelink transmission is performed on the first frequency domain resource; if the data channel is an uplink data channel, downlink transmission or sidelink transmission is performed on the first frequency domain resource; if the data channel is a first sidelink channel, uplink transmission, downlink transmission, or second sidelink transmission is performed on the first frequency domain resource.

[0104] In some embodiments, the present method is applicable to a communication scenario supporting XDD technology, where a first frequency domain resource exists in the time-frequency resources used by a network device to configure a data channel for a terminal device, and the first frequency domain resource cannot be used to transmit the data channel. Optionally, the first frequency domain resource is at least one of an uplink subband, a downlink subband, a sideband, and a guard sideband.

[0105] In some embodiments, the number of REs in the data channel is determined based on the target number of resource blocks; the amount of intermediate information carried by the data channel is determined based on the number of REs in the data channel; and the transmission block size is determined by quantized table lookup or quantized calculation based on the amount of intermediate information carried by the data channel.

[0106] In summary, the method provided in this embodiment determines the transport block size based on the target number of resource blocks. Because the target number of resource blocks determined based on the first number of resource blocks and the second number of resource blocks is closer to the number of resource blocks actually used during data transmission, the determined transport block size can be closer to the transport block size actually used during data transmission, thereby bringing the configured bit rate closer to the actual bit rate, which is beneficial to data transmission reliability.

[0107] The target number of resource blocks is determined based on the number of first resource blocks and the number of second resource blocks, and can be divided into at least the following three categories:

[0108] Type 1: The target number of resource blocks is determined based on the difference between the first number of resource blocks and the second number of resource blocks;

[0109] Type 2: The target number of resource blocks is determined based on the first number of resource blocks and the second number of resource blocks in the first transmission of repeated transmissions;

[0110] Type three: The target number of resource blocks is determined based on the first number of resource blocks and the second number of resource blocks in at least two transmissions in repeated transmissions.

[0111] Type 1: The target number of resource blocks is determined based on the difference between the first number of resource blocks and the second number of resource blocks

[0112] FIG6 is a flow chart illustrating a method for determining a transport block size provided by some exemplary embodiments of the present application. This method is illustrated by taking the network device 410, terminal device 420, or terminal device 430 shown in FIG4 as an example. The method includes at least some of the following steps:

[0113] Step 512: Determine a target number of resource blocks based on the difference between the first number of resource blocks and the second number of resource blocks;

[0114] The first number of resource blocks is the number of resource blocks configured for a data channel. The data channel may be a downlink data channel, such as a PDSCH; an uplink data channel, such as a PUSCH; or a sidelink data channel.

[0115] In some embodiments, the first number of resource blocks is the number of resource blocks dynamically configured for the data channel, for example, the first number of resource blocks is dynamically configured to the terminal device through downlink control information (DCI).

[0116] In some embodiments, the first number of resource blocks is indicated by a frequency domain resource indication field in DCI format 1-0, DCI format 1-1, or DCI format 1-2.

[0117] In some embodiments, the first number of resource blocks is the number of resource blocks semi-statically configured for the data channel. In some embodiments, the first number of resource blocks is indicated by activating a frequency domain resource indication field in a DCI format 1-0, DCI format 1-1, or DCI format 1-2 for semi-persistent scheduling (SPS).

[0118] The second number of resource blocks includes the number of resource blocks belonging to the first frequency domain resource in the first number of resource blocks. The first frequency domain resource cannot be used to transmit the data channel. The transmission direction of the frequency domain resource occupied by the data channel is different from the data transmission direction on the first frequency domain resource.

[0119] In some embodiments, the first frequency domain resource is configured by a network device.

[0120] In some embodiments, the first frequency domain resource is dynamically configured, or the first frequency domain resource is semi-statically configured.

[0121] The transmission direction of the frequency domain resource occupied by the data channel is different from the transmission direction of the first frequency domain resource. It can also be understood that the data transmission direction of the data channel is different from that of the first frequency domain resource. For example, if the data channel is a downlink data channel, uplink transmission or sideline transmission is performed on the first frequency domain resource; if the data channel is an uplink data channel, downlink transmission or sideline transmission is performed on the first frequency domain resource; if the data channel is a first sideline channel, uplink transmission, downlink transmission, or second sideline transmission is performed on the first frequency domain resource.

[0134] In some embodiments, as shown in FIG8 , the frequency domain resources corresponding to the time domain unit where the data channel is located include two resource parts for the data channel and one resource part belonging to the first frequency domain resource.

[0135] The target number of resource blocks is determined based on the difference between the first number of resource blocks and the second number of resource blocks. That is, the absolute value of the difference calculated by subtracting the second number of resource blocks from the first number of resource blocks is the target number of resource blocks.

[0136] Step 530: Determine the transport block size based on the target number of resource blocks.

[0137] In some embodiments, based on the target number of resource blocks, the number of REs in the data channel is determined, based on the number of REs in the data channel, the amount of intermediate information carried by the data channel is determined, and based on the amount of intermediate information carried by the data channel, the transmission block size is determined by quantitative table lookup or quantitative calculation.

[0138] In some embodiments, the amount of intermediate information carried by a data channel refers to the amount of intermediate information that the data channel may carry, and is not limited to the amount of intermediate information that the data channel must carry.

[0139] In some embodiments, the transport block size is determined based on at least one of a modulation scheme of the data channel, a number of transmission layers of the data channel, a code rate of the data channel, and a number of REs in the data channel.

[0140] In some embodiments, the transport block size is determined based on the modulation scheme of the data channel, the number of transmission layers of the data channel, the code rate of the data channel, and the number of REs in the data channel.

[0141] In some embodiments, based on the target number of resource blocks, the transport block size is determined as follows:

[0142] (1) According to the formula Calculate the number of REs in a resource block N′ RE .

[0143] in, Indicates the number of subcarriers in an RB; The number of symbols occupied by PDSCH in a time slot; is the number of REs occupied by DMRS in a PRB; The number of overhead REs configured within a PRB. The number of overhead REs includes the number of REs occupied by control information such as synchronization channels, PBCH, PDCCH, and PUCCH.

[0144] (2) Based on the target number of resource blocks, according to the formula N RE =min(156,N′ RE)×n PRB Determine the total number of REs N in the data channel RE .

[0145] Among them, n PRB =N3=N1-N2, N3 represents the target number of resource blocks, N1 represents the first number of resource blocks, and N2 represents the second number of resource blocks.

[0146] (3) Based on the total number of REs N in the data channel RE , according to the formula N info =N RE ×R×Q m ×υ calculates the amount of intermediate information N carried by the data channel info .

[0147] Among them, N RE is the total number of REs in the data channel calculated, R is the code rate of data transmission on the data channel, Q m is the modulation order of the data on the data channel, and υ represents the number of transmission layers of the data channel.

[0148] (4) Based on the amount of intermediate information N carried by the data channel info Determine the transport block size.

[0149] If the calculated N info ≤3824, the transport block size is determined by quantizing the table lookup.

[0150] If the calculated N info >3824, the transmission block size is determined by quantization calculation.

[0151] In some embodiments, the transport block size is determined according to a table lookup or calculation method in a relevant protocol of the 3rd Generation Partnership Project (3GPP) (eg, Section 5.1.3.2 of Version 17.2.0 of TS 38.214).

[0152] Step 550: Receive a transport block.

[0153] The size of the transport block is the transport block size determined based on the target number of resource blocks.

[0154] In some embodiments, the frequency domain resources corresponding to the transport blocks in the method provided in this embodiment are determined based on a dynamic scheduling method, and / or the frequency domain resources corresponding to the transport blocks are determined based on a semi-static scheduling method.

[0155] In some embodiments, when the method provided in this embodiment is used in a scenario where the transmission block is based on dynamic scheduling, that is, when the frequency domain resources corresponding to the transmission block in this embodiment are determined based on the dynamic scheduling method, the data channel is a downlink data channel, then the frequency domain resources of the downlink data channel are located in the downlink frequency domain resource part, that is, not in the uplink frequency domain resource part and / or the protection sideband and / or the side frequency domain resource part.

[0156] In some embodiments, when the method provided in this embodiment is used in a scenario where the transmission block is based on dynamic scheduling, that is, when the frequency domain resources corresponding to the transmission block in this embodiment are determined based on the dynamic scheduling method, the data channel is an uplink data channel, then the frequency domain resources of the uplink data channel are located in the uplink frequency domain resource part, that is, not in the downlink frequency domain resource part and / or the protection sideband and / or the side frequency domain resource part.

[0157] In some embodiments, when the method provided in this embodiment is used in a scenario where the transmission block is based on dynamic scheduling, that is, when the frequency domain resources corresponding to the transmission block in this embodiment are determined based on the dynamic scheduling method, the data channel is a first sidelink channel, then the frequency domain resources of the sidelink data channel are located in the first sidelink frequency domain resource part, that is, not in the uplink frequency domain resource part and / or the downlink frequency domain resource part and / or the protection sideband and / or the second sidelink frequency domain resource part.

[0158] In some embodiments, the method provided in this embodiment is applicable to the first frequency domain resource indication type and / or the second frequency domain resource indication type, wherein the first frequency domain resource indication type indicates the frequency domain resource corresponding to the transport block through a bitmap, and the second frequency domain resource indication type indicates the frequency domain resource corresponding to the transport block through a resource block starting number and a resource block consecutive length. In other words, the second frequency domain resource indication type indicates the frequency domain resource corresponding to the transport block through an RIV.

[0159] In some embodiments, the first frequency domain resource indication type is Type 0 described above, and the second frequency domain resource indication type is Type 1 described above.

[0160] In some embodiments, when the method provided in this embodiment is used for the first frequency domain resource indication type or Type 0, the data channel is a downlink data channel, then the frequency domain resources of the downlink data channel are located in the downlink frequency domain resource part, that is, not in the uplink frequency domain resource part and / or the protection sideband and / or the side frequency domain resource part.

[0161] In some embodiments, when the method provided in this embodiment is used for the first frequency domain resource indication type or Type 0, the data channel is an uplink data channel, then the frequency domain resources of the uplink data channel are located in the uplink frequency domain resource part, that is, not in the downlink frequency domain resource part and / or the protection sideband and / or the side frequency domain resource part.

[0162] In some embodiments, when the method provided in this embodiment is used for the first frequency domain resource indication type or Type 0, the data channel is a first sidelink channel, then the frequency domain resources of the sidelink data channel are located in the first sidelink frequency domain resource part, that is, not in the uplink frequency domain resource part and / or the downlink frequency domain resource part and / or the guard sideband and / or the second sidelink frequency domain resource part.

[0163] In summary, the method provided in this embodiment determines the transport block size based on the target number of resource blocks. Because the target number of resource blocks determined based on the first and second numbers of resource blocks is closer to the number of resource blocks actually used during data transmission, the determined transport block size can be closer to the actual transport block size used during data transmission, thereby bringing the configured bit rate closer to the actual bit rate, which is beneficial to data transmission reliability. Furthermore, because the first and second numbers of resource blocks can be configured dynamically or semi-statically, data transmission flexibility is enhanced.

[0164] Type 2: The target number of resource blocks is determined based on the first number of resource blocks and the second number of resource blocks in the first transmission of repeated transmissions.

[0165] FIG9 is a flow chart illustrating a method for determining a transport block size provided by some exemplary embodiments of the present application. This method is illustrated by taking the network device 410, terminal device 420, or terminal device 430 shown in FIG4 as an example. The method includes at least some of the following steps:

[0166] Step 514: Determine a target number of resource blocks based on the first number of resource blocks and the second number of resource blocks in the first transmission of repeated transmissions;

[0167] The target number of resource blocks is determined based on a difference between the number of first resource blocks in the first transmission of the repeated transmission and the number of second resource blocks. Specifically, the target number of resource blocks is determined by subtracting the number of second resource blocks in the first transmission of the repeated transmission from the number of first resource blocks in the first transmission of the repeated transmission.

[0168] Specifically, for determining the target number of resource blocks based on the difference between the first number of resource blocks and the second number of resource blocks in the first transmission in repeated transmission, reference may be made to step 512 in the aforementioned embodiment, which will not be repeated in this embodiment.

[0169] In some embodiments, the data in each of the repeated transmissions is the same.

[0170] Step 530: Determine the transport block size based on the target number of resource blocks.

[0171] Specifically, the relevant content of step 530 can refer to step 530 in the aforementioned embodiment, which will not be repeated in this embodiment.

[0172] In some embodiments, as shown in FIG10 , the terminal device 420 receives a DCI for scheduling PDSCH sent by the network device 410, indicating that six RBGs are allocated to the PDSCH, and the six RBGs are RBG 1, RBG 3, RBG 5, RBG 7, RBG 9, and RBG 11. Assuming that each RBG includes two PRBs, then N1=6×2=12. In some embodiments, an RBG may also include four, six, or eight PRBs, and the number of PRBs included in each RBG may be the same or different. In the first transmission of repeated transmission, three RBGs are located in the uplink resource part, then N 2,1 =3×2=6, then n PRB,1 = 12-6 = 6. However, in the subsequent m (m is an integer greater than 1) repeated transmissions, the number of PRBs in the uplink resource part of the six RBGs is not necessarily equal to six in each repeated transmission. For example, in the second repeated transmission, the number of PRBs in the uplink resource part of the six RBGs is zero, then N 2,2 =0,n PRB,2 =12-0=12, which means that during the second repeated transmission, all 12 PRBs in these six RBGs can be used to carry data on the PDSCH. In this calculation method, since the first transmission in the repeated transmission is usually directly configured by the network device, the network device can effectively control the resource conditions during the first transmission in the repeated transmission. Therefore, both the number of the first resource blocks and the number of the second resource blocks in the first repeated transmission and the configuration of the first frequency domain resources in the time domain unit of the current repeated transmission are considered to determine the target number of resource blocks. This facilitates accurate and flexible frequency domain resource management and achieves the expected results of the network device during the repeated transmission process.

[0173] For example, as shown in FIG11 , the terminal device 420 receives a DCI for scheduling a PDSCH from the network device 410, indicating that six RBGs are allocated to the PDSCH. The six RBGs are RBG 1, RBG 3, RBG 5, RBG 7, RBG 9, and RBG 11. Assuming that each RBG includes two PRBs, then N1 = 6 × 2 = 12. In the first transmission of the repeated transmission, three RBGs are located in the uplink resource part, so N 2,1 =3×2=6, then n PRB,1= 12-6 = 6. However, in the subsequent m (m is an integer greater than 1) repeated transmissions, the number of PRBs in the uplink resource part of the six RBGs is not necessarily equal to six in each repeated transmission. For example, in the second repeated transmission, the number of PRBs in the uplink resource part of the six RBGs is zero. Then, in the jth repeated transmission, the target number of resource blocks is still determined based on the first number of resource blocks and the second number of resource blocks in the first repeated transmission, that is, n PRB,j =n PRB,1 =6, where 1≤j≤m, and j is an integer. This calculation method ensures that the transport blocks in multiple repeated transmissions remain the same size, thereby achieving repetition gain. Furthermore, since the first transmission in a repeated transmission is typically directly configured by a network device, the network device can effectively control the resource availability during the first repeated transmission. Therefore, determining the target number of resource blocks based on the first and second numbers of resource blocks in the first repeated transmission facilitates achieving the desired effect of the network device during the repeated transmission process.

[0174] Step 550: Receive a transport block.

[0175] The size of the transport block is the transport block size determined based on the target number of resource blocks.

[0176] Specifically, the relevant content of step 550 can refer to step 550 in the aforementioned embodiment, which will not be repeated in this embodiment.

[0177] In summary, the method provided in this embodiment determines the target number of resource blocks based on the first number of resource blocks and the second number of resource blocks in the first transmission in repeated transmission, and determines the transmission block size based on the determined target number of resource blocks. This is beneficial for obtaining repetition gain by maintaining the same size of the transmission block in multiple repeated transmissions. Since the determined target number of resource blocks is closer to the number of resource blocks actually used in the data transmission process, the determined transmission block size can be made closer to the transmission block size actually used in the data transmission process, thereby making the configured code rate closer to the actual code rate, which is beneficial to the reliability of data transmission. Moreover, since the first transmission in repeated transmission is usually directly configured by the network device, the network device can well control the resource situation during the first transmission in repeated transmission. Therefore, the method provided in this embodiment is beneficial for achieving the expected effect of the network device in the repeated transmission scenario.

[0178] Type 3: The target number of resource blocks is determined based on the first number of resource blocks and the second number of resource blocks in at least two transmissions in repeated transmissions.

[0179] FIG12 is a flow chart illustrating a method for determining a transport block size provided by some exemplary embodiments of the present application. This method is illustrated by taking the network device 410, terminal device 420, or terminal device 430 shown in FIG4 as an example. The method includes at least some of the following steps:

[0180] Step 516: Determine a target number of resource blocks based on the first number of resource blocks and the second number of resource blocks transmitted in at least two repeated transmissions;

[0181] In some embodiments, the target number of resource blocks is the minimum or maximum or average or median of at least two third numbers of resource blocks, and the at least two third numbers of resource blocks are determined based on the first number of resource blocks and the second number of resource blocks in at least two transmissions in the repeated transmission.

[0182] In some embodiments, the third number of resource blocks in the kth repeated transmission is determined based on a difference between the first number of resource blocks and the second number of resource blocks in the kth repeated transmission in at least two transmissions in the repeated transmission; k is a positive integer, and k is not greater than the total number of repeated transmissions;

[0183] determining, based on the number of third resource blocks in each of the at least two transmissions in the repeated transmissions, a minimum value, a maximum value, an average value, or a median value of at least two numbers of third resource blocks in the at least two transmissions in the repeated transmissions;

[0184] The target number of resource blocks is determined based on a minimum value, a maximum value, an average value, or a median value of at least two third numbers of resource blocks in at least two transmissions in repeated transmissions.

[0185] In some instances, the absolute value of the difference between the first number of resource blocks and the second number of resource blocks in the kth repeated transmission in at least two transmissions in the repeated transmission is the third number of resource blocks in the kth repeated transmission.

[0186] Specifically, based on the difference between the first number of resource blocks and the second number of resource blocks in the kth repeated transmission in at least two transmissions in the repeated transmission, the relevant content of determining the third number of resource blocks in the kth repeated transmission can be referred to step 512 in the aforementioned embodiment, and will not be repeated in this embodiment.

[0187] In some embodiments, the data in each of the repeated transmissions is the same.

[0188] Step 530: Determine the transport block size based on the target number of resource blocks.

[0189] Specifically, the relevant content of step 530 can refer to step 530 in the aforementioned embodiment, which will not be repeated in this embodiment.

[0190] In some embodiments, as shown in FIG13 , the terminal device 420 receives a DCI for scheduling a PDSCH from the network device 410, indicating that six RBGs are allocated to the PDSCH. The six RBGs are RBG 1, RBG 3, RBG 5, RBG 7, RBG 9, and RBG 11. Assuming that each RBG includes two PRBs, then N1=6×2=12. In the first transmission of repeated transmission, there are zero RBGs in the uplink resource part, that is, N 2,1 =0, then n PRB,1 =12-0=12. During the second retransmission, three RBGs are located in the uplink resource part, namely N 2,2 =3×2=6, then n PRB,2 =12-6=6. Then, in the subsequent m (m is an integer greater than 1) repeated transmissions, in the pth repeated transmission, since min{12,6}=6, the number of third resource blocks in the second repeated transmission is smaller than the number of third resource blocks in the first repeated transmission. Therefore, the number of third resource blocks in the second repeated transmission is determined as the target number of resource blocks in the pth repeated transmission, that is, n PRB,p =n PRB,2 =6, where 2≤p≤m, and p is an integer. This calculation method determines the transport block size based on the smallest number of third resource blocks in at least two repeated transmissions. This supports multiple repeated transmissions using the same frequency domain resources for data transmission, reducing data transmission complexity and improving data transmission simplicity.

[0191] Step 550: Receive a transport block.

[0192] The size of the transport block is the transport block size determined based on the target number of resource blocks.

[0193] Specifically, the relevant content of step 550 can refer to step 550 in the aforementioned embodiment, which will not be repeated in this embodiment.

[0194] In summary, the method provided in this embodiment determines the target number of resource blocks based on the minimum, maximum, average, or median value of at least two third numbers of resource blocks in at least two transmissions in repeated transmissions, determines the transport block size based on the target number of resource blocks, supports multiple repeated transmissions using the same frequency domain resources for data transmission, reduces the complexity of data transmission, and improves the simplicity of data transmission. Because the target number of resource blocks determined based on the first number of resource blocks and the second number of resource blocks in at least two transmissions in repeated transmissions is closer to the number of resource blocks actually used during data transmission, the determined transport block size can be closer to the transport block size actually used during data transmission, thereby making the configured code rate closer to the actual code rate, which is beneficial to the reliability of data transmission. In addition, because the first number of resource blocks and the second number of resource blocks can be dynamically or semi-statically configured, the flexibility of data transmission is improved.

[0195] FIG14 is a flow chart illustrating a method for determining a transport block size provided by some exemplary embodiments of the present application. This method is illustrated by taking the case where the data channel is a PDSCH and the method is performed by the network device 410 and the terminal device 420 shown in FIG4 as an example. The method includes at least some of the following steps:

[0196] Step 1210: Determine the number of REs for the PDSCH based on the second number of resource blocks, where the second number of resource blocks is the number of resource blocks in the first number of resource blocks that partially overlap with the configured uplink resources;

[0197] By formula Determine the number of REs in an RB. Indicates the number of subcarriers in an RB; The number of symbols occupied by PDSCH in a time slot; is the number of REs occupied by DMRS in a PRB; The number of overhead REs configured within a PRB. The number of overhead REs includes the number of REs occupied by control information such as synchronization channels, PBCH, PDCCH, and PUCCH.

[0198] By formula N RE =min(156,N′ RE )×n PRB Determine the total number of REs N in PDSCH RE .

[0199] Among them, n PRB =N3=N1-N2, N3 represents the target number of resource blocks, N1 represents the first number of resource blocks, and N2 represents the second number of resource blocks.

[0200] In some embodiments, the first number of resource blocks is the number of resource blocks of the configured PDSCH, and the second number of resource blocks is the number of resource blocks in the first number of resource blocks that overlap with the configured uplink resource portion. It can also be understood that the second number of resource blocks is the number of resource blocks in the configured uplink resource portion used to transmit downlink data.

[0201] In some embodiments, as shown in FIG15 , the terminal device 420 receives a DCI for scheduling a PDSCH from the network device 410, indicating that five RBGs are allocated to the PDSCH. The five RBGs are RBG 3, RBG 5, RBG 7, RBG 9, and RBG 11. Assuming that each RBG includes two PRBs, then N1 = 5 × 2 = 10. Among them, there are two RBGs located in the uplink resource part, that is, N2 = 2 × 2 = 4, then n PRB =N3=10-4=6.

[0202] In some embodiments, the data channel is PUSCH, then the first number of resource blocks is the number of resource blocks of PUSCH configured by the network device, and the second number of resource blocks is the number of resource blocks in the first number of resource blocks that overlap with the configured downlink resource portion. It can also be understood that the second number of resource blocks is the number of resource blocks in the configured downlink resource portion used to transmit uplink data.

[0203] Step 1230: Determine the amount of intermediate information carried by the PDSCH;

[0204] By formula N info =N RE ×R×Q m ×υ determines the amount of intermediate information N carried by PDSCH info Among them, N RE is the total number of REs in the PDSCH calculated, R is the code rate of data transmission on the PDSCH, and Q m It is the modulation order of the data on PDSCH, and υ represents the number of transmission layers of PDSCH.

[0205] Step 1250: Determine the transport block size on the PDSCH.

[0206] Determine the transport block size on PDSCH based on the amount of intermediate information carried by PDSCH and the transport block size on DSCH.

[0207] If the calculated N info ≤3824, the transport block size is determined by quantizing the table lookup.

[0208] If the calculated N info >3824, the transmission block size is determined by quantization calculation.

[0209] In some embodiments, the transport block size is determined according to a table lookup or calculation method in a relevant protocol of the 3rd Generation Partnership Project (3GPP) (eg, Section 5.1.3.2 of Version 17.2.0 of TS 38.214).

[0210] In summary, the method provided in this embodiment determines the transport block size based on the target number of resource blocks. Because the target number of resource blocks determined based on the first and second numbers of resource blocks is closer to the number of resource blocks actually used during data transmission, the determined transport block size is closer to the actual transport block size used during data transmission, thereby bringing the configured code rate closer to the actual code rate, which is beneficial to data transmission reliability. Furthermore, determining the second number of resource blocks based on the uplink resource portion allows the PDSCH to utilize the guard sideband for downlink data transmission, resulting in higher frequency domain resource utilization.

[0211] FIG16 is a flow chart illustrating a method for determining a transport block size provided by some exemplary embodiments of the present application. This method is illustrated by taking the case where the data channel is a PDSCH and the method is performed by the network device 410 and the terminal device 420 shown in FIG4 as an example. The method includes at least some of the following steps:

[0212] Step 1410: Determine the number of REs for the PDSCH based on the second number of resource blocks, where the second number of resource blocks is the sum of the number of resource blocks in the first number of resource blocks that partially overlap with the configured uplink resources and the number of resource blocks in the first number of resource blocks that overlap with the guard sideband.

[0213] By formula Determine the number of REs in an RB. Indicates the number of subcarriers in an RB; The number of symbols occupied by PDSCH in a time slot; is the number of REs occupied by DMRS in a PRB; The number of overhead REs configured within a PRB. The number of overhead REs includes the number of REs occupied by control information such as synchronization channels, PBCH, PDCCH, and PUCCH.

[0214] By formula N RE =min(156,N′ RE )×n PRB Determine the total number of REs N in PDSCH RE .

[0215] Among them, n PRB=N3=N1-N2, N3 represents the target number of resource blocks, N1 represents the first number of resource blocks, and N2 represents the second number of resource blocks.

[0216] In some embodiments, the first number of resource blocks is the number of resource blocks configured for PDSCH, and the second number of resource blocks is the number of resource blocks N in the first number of resource blocks that partially overlap with the configured uplink resources. UL and the number of resource blocks N that overlap with the guard band in the first number of resource blocks GUARD The sum of the second resource blocks can also be understood as the number of resource blocks N used to transmit downlink data in the configured uplink resource part. UL and the number of resource blocks in the guard sideband used to transmit downlink data.

[0217] In some embodiments, as shown in FIG17 , the terminal device 420 receives a DCI for scheduling a PDSCH from the network device 410, indicating that six RBGs are allocated to the PDSCH. The six RBGs are RBG 1, RBG 3, RBG 5, RBG 7, RBG 9, and RBG 11. Assuming that each RBG includes two PRBs, then N1=6×2=12. Among them, two RBGs are located in the uplink resource part, namely RBG 5 and RBG 7, and one RBG is located in the guard sideband, namely RBG 9, that is, N UL =2×2=4, N GUARD =1×2=2, then N2=N UL +N GUARD =4+2=6, then n PRB =N3=12-6=6.

[0218] In some embodiments, the data channel is PUSCH, then the first number of resource blocks is the number of resource blocks of PUSCH configured by the network device, and the second number of resource blocks is the sum of the number of resource blocks in the first number of resource blocks that overlap with the configured downlink resource portion and the number of resource blocks in the first number of resource blocks that overlap with the protection sideband. It can also be understood that the second number of resource blocks is the sum of the number of resource blocks in the configured downlink resource portion used to transmit uplink data and the number of resource blocks in the protection sideband used to transmit uplink data.

[0219] Step 1430: Determine the amount of intermediate information carried by the PDSCH;

[0220] By formula N info =N RE ×R×Q m ×υ determines the amount of intermediate information N carried by PDSCH info Among them, N RE is the total number of REs in the PDSCH calculated, R is the code rate of data transmission on the PDSCH, and Qm It is the modulation order of the data on PDSCH, and υ represents the number of transmission layers of PDSCH.

[0221] Step 1450: Determine the transport block size on the PDSCH.

[0222] The transport block size on the PDSCH is determined based on the amount of intermediate information carried by the PDSCH.

[0223] If the calculated N info ≤3824, the transport block size is determined by quantizing the table lookup.

[0224] If the calculated N info >3824, the transmission block size is determined by quantization calculation.

[0225] In some embodiments, the transport block size is determined according to a table lookup or calculation method in a relevant protocol of the 3rd Generation Partnership Project (3GPP) (eg, Section 5.1.3.2 of Version 17.2.0 of TS 38.214).

[0226] In summary, the method provided in this embodiment determines the transport block size based on the target number of resource blocks. Because the target number of resource blocks determined based on the first and second numbers of resource blocks is closer to the number of resource blocks actually used during data transmission, the determined transport block size is closer to the actual transport block size used during data transmission, thereby bringing the configured bit rate closer to the actual bit rate, which is beneficial to data transmission reliability. Furthermore, determining the second number of resource blocks based on the uplink resource portion and the guard sideband helps reduce interference with uplink transmissions and reduces the complexity and cost of interference cancellation.

This method is illustrated by taking the case where the data channel is a PDSCH and the method is performed by the network device 410 and the terminal device 420 shown in FIG4 as an example. The method includes at least some of the following steps:

[0229] By formula Determine the number of REs in an RB. Indicates the number of subcarriers in an RB; The number of symbols occupied by PDSCH in a time slot; is the number of REs occupied by DMRS in a PRB; The number of overhead REs configured within a PRB. The number of overhead REs includes the number of REs occupied by control information such as synchronization channels, PBCH, PDCCH, and PUCCH.

[0230] By formula N RE =min(156,N′ RE )×n PRB Determine the total number of REs N in PDSCH RE .

[0231] Among them, n PRB =N3=N1-N2, N3 represents the target number of resource blocks, N1 represents the first number of resource blocks, and N2 represents the second number of resource blocks.

[0232] In some embodiments, the first number of resource blocks is the number of resource blocks configured for the PDSCH, and the second number of resource blocks is the number of resource blocks in the first number of resource blocks that overlap with the configured uplink resource portion. Alternatively, the second number of resource blocks is the sum of the number of resource blocks in the first number of resource blocks that overlap with the configured uplink resource portion and the number of resource blocks in the first number of resource blocks that overlap with the guard sideband. Alternatively, the second number of resource blocks is the sum of the number of resource blocks in the configured uplink resource portion that overlap with the configured uplink resource portion and the number of resource blocks in the first number of resource blocks that overlap with the guard sideband. Alternatively, the second number of resource blocks is the sum of the number of resource blocks in the configured uplink resource portion that transmit downlink data and the number of resource blocks in the guard sideband that transmit downlink data.

[0233] In some embodiments, as shown in FIG19 , the terminal device 420 receives the DCI for scheduling the PDSCH sent by the network device 410. The network device uses Type 0 to indicate that two RBGs are allocated to the PDSCH. The two RBGs are RBG 1 and RBG 4, and each RBG contains 4 RBs, that is, N1=2×4=8. Among them, there are two PRBs in the uplink resource part, that is, N2=2, then n PRB = N3 = 8 - 2 = 6. In this calculation method, the number of second resource blocks is determined with RB as the granularity, which can perform accurate frequency domain resource management and improve resource utilization.

[0234] In some embodiments, the data channel is PUSCH, then the first number of resource blocks is the number of resource blocks of PUSCH configured by the network device, and the second number of resource blocks is the number of resource blocks in the first number of resource blocks that overlap with the configured downlink resource portion. It can also be understood that the second number of resource blocks is the number of resource blocks in the configured downlink resource portion used to transmit uplink data.

[0236] In some embodiments, the terminal device 420 receives a DCI for scheduling a PDSCH sent by the network device 410. The network device uses Type 0 to indicate that two RBGs are allocated to the PDSCH. The two RBGs are RBG 1 and RBG 4, and each RBG contains 4 RBs, that is, N1 = 2 × 4 = 8. Among them, a part or all of the PRBs in one RBG are located in the uplink resource part. Assuming that one PRB in RBG 1 overlaps with the uplink resource part, the second number of resource blocks is the number of PRBs in the RBG that overlap with the uplink resource part, that is, N2 = 1, then n PRB = N3 = 8-1 = 7; or, as shown in FIG20 , a part or all of the PRBs in one RBG are located in the uplink resource part. Assuming that one PRB in RBG 4 overlaps with the uplink resource part, the number of the second resource blocks is the number of all PRBs in RBG 4, that is, N2 = 4, then n PRB = N3 = 8 - 4 = 4. In this calculation method, the number of second resource blocks is determined with RBG as the granularity, which can perform simple and convenient frequency domain resource management and improve the simplicity of resource management.

[0237] In some embodiments, the data channel is PUSCH, then the first number of resource blocks is the number of resource blocks of PUSCH configured by the network device, and the second number of resource blocks is the number of resource blocks in the first number of resource blocks that overlap with the configured downlink resource portion. It can also be understood that the second number of resource blocks is the number of resource blocks in the configured downlink resource portion used to transmit uplink data.

[0238] In some embodiments, the data channel is PUSCH, then the first number of resource blocks is the number of resource blocks of PUSCH configured by the network device, and the second number of resource blocks is the sum of the number of resource blocks in the first number of resource blocks that overlap with the configured downlink resource portion and the number of resource blocks in the first number of resource blocks that overlap with the protection sideband. It can also be understood that the second number of resource blocks is the sum of the number of resource blocks in the configured downlink resource portion used to transmit uplink data and the number of resource blocks in the protection sideband used to transmit uplink data.

[0239] Step 1630: Determine the amount of intermediate information carried by the PDSCH;

[0240] By formula N info =N RE ×R×Q m ×υ determines the amount of intermediate information N carried by PDSCH info Among them, N RE is the total number of REs in the PDSCH calculated, R is the code rate of data transmission on the PDSCH, and Q m It is the modulation order of the data on PDSCH, and υ represents the number of transmission layers of PDSCH.

[0241] Step 1650: Determine the transport block size on the PDSCH.

[0242] The transport block size on the PDSCH is determined based on the amount of intermediate information carried by the PDSCH.

[0243] If the calculated N info ≤3824, the transport block size is determined by quantizing the table lookup.

[0244] If the calculated N info >3824, the transmission block size is determined by quantization calculation.

[0245] In some embodiments, the transport block size is determined according to a table lookup or calculation method in a relevant protocol of the 3rd Generation Partnership Project (3GPP) (eg, Section 5.1.3.2 of Version 17.2.0 of TS 38.214).

[0246] In summary, the method provided in this embodiment determines the transport block size based on the target number of resource blocks in scenarios where frequency domain resources are indicated via Type 0. Because the target number of resource blocks determined based on the first and second numbers of resource blocks is closer to the number of resource blocks actually used during data transmission, the determined transport block size can be closer to the actual transport block size used during data transmission, thereby bringing the configured code rate closer to the actual code rate, which is beneficial to data transmission reliability. Furthermore, the method supports determining the second number of resource blocks at the RB granularity, enabling precise frequency domain resource management and improving resource utilization. It also supports determining the second number of resource blocks at the RBG granularity, enabling simple and convenient frequency domain resource management and improving the simplicity of resource management.

[0250] By formula N RE =min(156,N′ RE )×n PRB Determine the total number of REs N in PDSCH RE .

[0251] Among them, n PRB =N3=N1-N2, N3 represents the target number of resource blocks, N1 represents the first number of resource blocks, and N2 represents the second number of resource blocks.

[0252] In some embodiments, the first number of resource blocks is the number of resource blocks configured for the PDSCH, and the second number of resource blocks is the number of resource blocks in the first number of resource blocks that overlap with the configured uplink resource portion. Alternatively, the second number of resource blocks is the sum of the number of resource blocks in the first number of resource blocks that overlap with the configured uplink resource portion and the number of resource blocks in the first number of resource blocks that overlap with the guard sideband. Alternatively, the second number of resource blocks is the sum of the number of resource blocks in the configured uplink resource portion that overlap with the configured uplink resource portion and the number of resource blocks in the first number of resource blocks that overlap with the guard sideband. Alternatively, the second number of resource blocks is the sum of the number of resource blocks in the configured uplink resource portion that transmit downlink data and the number of resource blocks in the guard sideband that transmit downlink data.

[0253] In some embodiments, as shown in FIG22 , the terminal device 420 receives the DCI for scheduling the PDSCH sent by the network device 410. The network device uses Type 1 to indicate that the six RBs from RB2 to RB7 are allocated to the PDSCH, that is, N1=6. Among them, one PRB is located in the uplink resource part, that is, N2=1, then n PRB = N3 = 6 - 1 = 5. In this calculation method, the number of second resource blocks is determined with RB as the granularity, which can perform accurate frequency domain resource management and improve resource utilization.

It can also be understood that the second number of resource blocks is the number of resource blocks in the configured downlink resource portion used to transmit uplink data.

[0255] In some embodiments, the data channel is PUSCH, then the first number of resource blocks is the number of resource blocks of PUSCH configured by the network device, and the second number of resource blocks is the sum of the number of resource blocks in the first number of resource blocks that overlap with the configured downlink resource portion and the number of resource blocks in the first number of resource blocks that overlap with the protection sideband. It can also be understood that the second number of resource blocks is the sum of the number of resource blocks in the configured downlink resource portion used to transmit uplink data and the number of resource blocks in the protection sideband used to transmit uplink data.

[0256] Step 1930: Determine the amount of intermediate information carried by the PDSCH;

[0257] By formula N info =N RE ×R×Q m ×υ determines the amount of intermediate information N carried by PDSCH info Among them, N RE is the total number of REs in the PDSCH calculated, R is the code rate of data transmission on the PDSCH, and Q m It is the modulation order of the data on PDSCH, and υ represents the number of transmission layers of PDSCH.

[0258] Step 1950: Determine the transport block size on the PDSCH.

[0259] The transport block size on the PDSCH is determined based on the amount of intermediate information carried by the PDSCH.

[0260] If the calculated N info ≤3824, the transport block size is determined by quantizing the table lookup.

[0261] If the calculated N info >3824, the transmission block size is determined by quantization calculation.

[0262] In some embodiments, the transport block size is determined according to a table lookup or calculation method in a relevant protocol of the 3rd Generation Partnership Project (3GPP) (eg, Section 5.1.3.2 of Version 17.2.0 of TS 38.214).

[0263] In summary, the method provided in this embodiment determines the transport block size based on the target number of resource blocks in scenarios where frequency domain resources are indicated using Type 1. Because the target number of resource blocks determined based on the first and second numbers of resource blocks is closer to the number of resource blocks actually used during data transmission, the determined transport block size can be closer to the actual transport block size used during data transmission, thereby bringing the configured bit rate closer to the actual bit rate, which is beneficial to data transmission reliability. Furthermore, support for determining the second number of resource blocks at the RB granularity enables precise frequency domain resource management and improves resource utilization.
