Description

Technical Field

[0001] The present disclosure relates to communication technology, and in particular to a communication method, apparatus, device, storage medium, and program product. Background Art

[0002] Cellular mobile communication uses cellular wireless networking to connect terminals and network equipment via wireless channels, enabling user terminals to communicate with each other while on the move. Its primary feature is terminal mobility, including handover and automatic roaming across local networks.

[0003] As the signal frequency in mobile communication technology increases, the signal loss during propagation increases. For example, in 5G NR (New Radio) systems, as the frequency of wireless system deployment increases, the loss of wireless signal propagation increases, which in turn shortens the signal transmission distance and reduces network coverage performance.

[0004] Especially when a user terminal (User Equipment, UE) performs uplink transmission, since the transmission power of the UE is relatively low, the coverage of the uplink channel is more limited than that of the downlink channel. Summary of the Invention

[0117] Figure 1 A communication scenario diagram.

[0118] like Figure 1 As shown, a communication system includes a network device 11 and a user terminal 12 , and the user terminal 12 can send an uplink signal to the network device 11 .

[0119] User terminals 12 can initiate random access requests to network device 11 to request wireless network connection services. Network device 11 receives random access requests from at least one user terminal 12 and provides wireless services for the user terminal. Network device 11 and user terminals 12 exchange and transmit data via wireless communication.

[0120] Specifically, when user terminal 12 sends an uplink signal to network device 11, as the signal frequency required by communication technology increases, the signal loss during propagation increases. This is especially true for user terminals located in areas with high fading, such as cell edges or basements, where uplink signal propagation loss is high. Therefore, coverage enhancement is required.

[0121] Figure 2 This is a data transmission diagram showing an exemplary embodiment of the present application.

[0122] like Figure 2 As shown, in existing communication technologies, a transport block (TB) 21 can only be transmitted in a physical uplink shared channel (PUSCH) of a single time slot. For example, 300 bits of data can be transmitted in each slot, and the 300 bits of data are a 300-bit coded block obtained by encoding a 200-bit transport block. It should be noted that what the UE sends in the PUSCH is often a coded block after channel coding, but in essence it still sends the information in the transport block. Therefore, sending a transport block, transmitting a transport block, sending a coded block, and transmitting a coded block are interchangeable in this application.

[0123] In scenarios with poor coverage, the signal of the user terminal in a single slot often needs to concentrate energy and be sent in a narrowband. This makes the number of bits sent in a single slot very limited. As a result, the TB encoded by the user terminal for sending PUSCH is very short, which reduces the coding performance and thus deteriorates the coverage.

[0125] like Figure 3 As shown, in order to improve the network coverage of user terminals, the solution provided in this application proposes a solution for sending transport blocks using a multi-slot PUSCH.

[0126] like Figure 3 As shown, multiple PUSCH slots can be used to carry the same TB 31. This ensures narrowband, high-power-density transmission while increasing the encoding code length, thereby improving coding gain and, in turn, coverage performance. For example, when a TB is transmitted across four PUSCH slots, 800 bits of data can be transmitted, and the encoded code length is 1200.

[0127] Figure 4 The flowchart of the communication method is shown as an exemplary embodiment of the present application.

[0128] like Figure 4 As shown, the communication method provided by this application includes:

[0129] Step 401 : determining a transport block size according to time-frequency resources occupied by a physical uplink shared channel PUSCH; the time-frequency resources occupied by a multi-slot PUSCH include time-frequency resources in multiple time slots.

[0130] The method provided in this application may be executed by a user terminal. When the user terminal needs to send data to a network device, the transmission block size may be determined based on the time-frequency resources occupied by the physical uplink shared channel PUSCH.

[0131] In a communication system, a network device may send control information to a user terminal for instructing the user terminal to transmit a transport block based on a multi-slot PUSCH. Therefore, in an optional embodiment, the user terminal may respond to the control information sent by the network device and send data to the network device. For example, the control information may be Radio Resource Control (RRC) signaling. For example, the network device may configure the user terminal through RRC signaling to transmit a TB through a multi-slot PUSCH. For example, the control information may also be downlink control information (DCI). The network device may also send DCI to the user terminal and schedule the user terminal to transmit a TB in a multi-slot PUSCH through the DCI.

[0132] Optionally, a configured grant may be provided so that the user terminal can autonomously send the PUSCH on semi-statically configured resources. The configured resources may be, for example, time-frequency resources spanning multiple time slots.

[0133] In actual application, when a user terminal needs to send data, it can determine the transport block size (TBS) based on the time-frequency resources occupied by the multi-slot PUSCH. The time-frequency resources occupied by the multi-slot PUSCH include the time-frequency resources in multiple slots.

[0134] In the method provided in the present application, a TB is transmitted based on a multi-slot PUSCH. Therefore, the size of a TB depends on the slot range occupied by the PUSCH and the range of the physical resource block (PRB) occupied by the PUSCH.

[0135] The multi-slot PUSCH occupies several slots in the time domain and several PRBs in the frequency domain. The total number of resource elements (REs) of the PUSCH can be determined based on the number of slots and PRBs occupied by the multi-slot PUSCH.

[0136] Specifically, each slot includes several symbols, and each PRB also includes several subcarriers. Therefore, the total number of resource elements (RE) of the PUSCH can be determined based on the number of slots occupied by the PUSCH, the number of PRBs occupied by the PUSCH, the number of symbols used to carry the PUSCH in a slot, and the number of subcarriers included in the PRB.

[0137] Furthermore, when a user terminal transmits data, the PUSCH needs to carry some information other than data, such as the Demodulation Reference Signal (DMRS). The number of REs used to carry information other than data can be calculated by subtracting the number of REs occupied by the PUSCH from the total number of REs used to carry data.

[0138] In actual applications, since the terminal can only transmit in the currently activated bandwidth part (BWP), the bandwidth of the terminal sending PUSCH cannot exceed the bandwidth of its BWP, and the size of the transport block carried by the PUSCH cannot exceed the maximum data volume corresponding to its BWP. Therefore, it is also possible to set a preset number of available resource particles, and use the smaller value of the number of available REs in the PUSCH and the preset number of available resource particles as the transport block size TBS. This will result in the maximum TBS that the PUSCH can carry.

[0139] Step 402: Obtain a transport block corresponding to the transport block size, encode the transport block to obtain a coded block, and send the coded block through the PUSCH.

[0140] The user terminal can obtain data information from the upper layer according to the TBS, thereby obtaining a transport block TB, and the size of the obtained TB is consistent with the determined TBS. For example, the determined TBS is N InFo , you can get the length N Info TB.

[0141] Specifically, the user terminal can encode the acquired TB to obtain a code block (CB) and send the generated code block via a multi-slot PUSCH. Since the code block is obtained by encoding the transport block, when the size of the transport block is fixed, the size of the code block can also be fixed.

[0142] In this implementation, the size of the transport block obtained in a single time can be increased, which in turn increases the size of the coding block, thereby allowing more data to be sent through one coding, reducing the number of coding times and the overhead of cyclic redundancy check bits, thereby improving data transmission efficiency.

[0143] In addition, in scenarios with poor coverage, by carrying the same TB through multiple-slot PUSCHs and sending the coding blocks corresponding to the TB in narrowband and high power, the code length can be increased, thereby improving the coding gain and thus the coverage performance.

[0144] The method provided in this embodiment is used to send a transport block via a multi-slot physical uplink shared channel, thereby improving the coverage performance of a user terminal. The method is performed by a device equipped with the method provided in this embodiment, which is generally implemented in hardware and / or software.

[0145] The communication method provided by this application includes: determining a transport block size based on the time-frequency resources occupied by a multi-slot physical uplink shared channel (PUSCH), where the time-frequency resources occupied by the multi-slot PUSCH include time-frequency resources in multiple time slots; obtaining a transport block corresponding to the transport block size, encoding the transport block to obtain a coded block, and transmitting the coded block via the multi-slot PUSCH. In this implementation, the transport block size can be increased, thereby allowing more data to be transmitted through a single encoding, thereby increasing coding gain and improving coverage performance.

[0146] Figure 5 This is a flow chart of a communication method according to another exemplary embodiment of the present application.

[0147] like Figure 5 As shown, the communication method provided by this application includes:

[0148] Step 501 : Determine the number of available resource particles for the multi-slot PUSCH according to the time-frequency resources occupied by the multi-slot PUSCH and a preset upper limit of available resource particles.

[0149] The method provided in this application may be executed by a user terminal. When the user terminal needs to send data to a network device, it may first determine the transport block size based on the time-frequency resources occupied by the physical uplink shared channel PUSCH.

[0150] In an optional implementation, the number of slots occupied by the multi-slot PUSCH can be configured for the user terminal by the network device. For example, the network device can configure the multi-slot PUSCH for the user terminal to occupy a total of 4 slots. In another implementation, the number of slots occupied by the multi-slot PUSCH can also be configured for the user terminal by configuring the permission. In another implementation, the network device can indicate the number of slots occupied by the multi-slot PUSCH to the user terminal through the DCI. Some rules for determining the slots can also be set, and the user terminal can determine the number of slots by itself. It is only necessary to make the network device and the terminal device have the same understanding of the number of slots occupied by the multi-slot PUSCH. This embodiment does not limit this.

[0151] Specifically, the multi-slot PUSCH occupies several PRBs in the frequency domain. The network device can configure the specific number of PRBs occupied by the multi-slot PUSCH of the user terminal, or configure the number of PRBs occupied by the multi-slot PUSCH for the user terminal by configuring a permission, or the network device can indicate the number of PRBs occupied by the multi-slot PUSCH of the user terminal through DCI, or the user terminal can determine the number of PRBs occupied by the multi-slot PUSCH based on certain rules. This embodiment is not limited to this.

[0152] Furthermore, the number of REs that can be used to carry data in the multi-slot PUSCH can be determined according to the time-frequency resources occupied by the multi-slot PUSCH.

[0153] In practice, REs are the data-carrying units in the multi-slot PUSCH, specifically code blocks. When a user terminal transmits data, some REs are used to carry information other than data. For example, if some REs need to carry DMRS, these REs cannot carry other data.

[0154] A resource element includes a symbol in the time domain and a subcarrier in the frequency domain. A slot includes several symbols, and a PRB includes several subcarriers. The user terminal can also determine the number of REs required to carry information other than data based on configuration information or preset rules. Therefore, combined with the above information, the user terminal can determine the number of REs that can be used to carry data in the multi-slot PUSCH.

[0155] An upper limit value of available resource particles may also be preset, and the upper limit value of available resource particles may be the maximum number of resource particles that can be used when transmitting data and is determined based on a reference bandwidth.

[0156] Specifically, the smaller value between the number of REs that can be used to carry data in the multi-slot PUSCH and the upper limit of the available resource particles can be determined as the number of available resource particles N for the multi-slot PUSCH. RE .

[0157] Step 502: Determine the transport block size based on the product of the number of available resource particles, the coding rate, the modulation order, and the number of transmission layers.

[0158] Determine the number of available resource particles N for multi-slot PUSCH RE Afterwards, the user terminal can also RE , coding rate, modulation order, and number of transmission layers to determine TBS.

[0159] Furthermore, according to N RE The TBS is determined by multiplying the product of the encoding rate, the modulation order, and the number of transmission layers. For example, the value of the product can be directly used as the TBS. For another example, after determining the product, the product can be processed in other ways to obtain the TBS. For example, the product can be quantized in multiples of 8 bits according to predefined rules.

[0160] Step 503: Obtain a transport block corresponding to the transport block size, encode the transport block to obtain a coded block, and send the coded block through a multi-slot PUSCH.

[0161] Step 503 is similar to step 402 and will not be described in detail.

[0162] In an optional embodiment, when determining the number of available resource particles N for the PUSCH of multiple slots, RE When the time-frequency resources occupied by the multi-slot PUSCH are used, the number of available resource particles N′ in multiple time slots of a physical resource block occupied by the multi-slot PUSCH can be determined. RE .

[0163] Among them, when using multi-slot PUSCH to send a transport block, the multi-slot PUSCH occupies multiple slots in the time domain and multiple PRBs in the frequency domain. The number of available resource particles N' included in multiple slots of a PRB occupied by the PUSCH can be determined RE .

[0164] The multi-slot PUSCH occupies multiple slots in the time domain and multiple PRBs in the frequency domain. Each time domain segment contains n symbols. For example, in a slot, the multi-slot PUSCH can occupy n1 symbols, and each PRB contains n2 subcarriers. Therefore, a PRB occupied by the multi-slot PUSCH contains a total of n1*n2 REs in a slot.

[0165] In an optional implementation manner, n=14, and the multi-slot PUSCH occupies the first 12 symbols in one slot, then n1=12, n2=12.

[0166] Furthermore, since the multi-slot PUSCH needs to carry some information other than data, for example, it needs to carry DMRS, which results in the need to occupy some REs in the multi-slot PUSCH. Therefore, based on the time-frequency resources occupied by PUSCH, the number of remaining available resource particles N' in multiple slots of a PRB occupied by the multi-slot PUSCH can be determined. RE Then according to N′ ′RR The number of REs that can be used to carry data in the entire PUSCH is determined by the number of PRBs occupied by the multi-slot PUSCH.

[0167] The time-frequency resources occupied by the PUSCH of multiple slots in each PRB are the same, so N′ RE The product of the number of PRBs occupied by the multi-slot PUSCH is used as the number of REs that can be used to carry data in the multi-slot PUSCH.

[0168] An upper limit value of available resource particles may also be preset, and the upper limit value of available resource particles may be the maximum number of resource particles that can be used when transmitting data and is determined based on a reference bandwidth.

[0169] For example, the upper limit of available resource particles may be the number of available resource particles in one slot when a multi-slot PUSCH occupies the reference bandwidth. For another example, if a multi-slot PUSCH occupies N slots, the upper limit of available resource particles may also be the number of available resource particles in the N slots of the reference bandwidth.

[0170] N′ can be REThe smaller value of the product of the number of physical resource blocks occupied by the multi-slot PUSCH and the preset upper limit of the available resource particles is determined as the number of available resource particles N for the multi-slot PUSCH RE In this implementation, the maximum number of resource elements that can be carried by the multi-slot PUSCH and does not exceed the reference bandwidth carrying upper limit can be determined, thereby making full use of the PUSCH for data transmission.

[0171] Specifically, the number of available resource particles N for multi-slot PUSCH RE for:

[0172] N RE =min(N′ RE ·n PRB , preset upper limit of available resource particles)

[0173] Among them, n PRB The number of physical resource blocks occupied by PUSCH.

[0174] In an optional implementation, the number of time slots K occupied by the multi-slot PUSCH and the number of subcarriers included in a physical resource block can be used. The number of symbols occupied by the multi-slot PUSCH in the reference slot The number of resource elements used by a physical resource block occupied by a multi-slot PUSCH to carry the demodulation reference signal in the reference time slot The number of resource elements used for additional overhead in the reference time slot of a physical resource block occupied by a multi-slot PUSCH Determine the number of available resource particles N' in multiple time slots for a physical resource block occupied by a multi-slot PUSCH RE .

[0175] Specifically, the number of available REs N′ in a physical resource block occupied by a multi-slot PUSCH in the multiple slots occupied by the PUSCH RE for:

[0176]

[0177] The reference slot may be a slot determined according to a preset rule or a slot configured by a network device for a user terminal. The determination of whether a PRB occupied by a multi-slot PUSCH carries data in multiple slots may be based on whether a PRB occupied by a multi-slot PUSCH carries data in the reference slot.

[0178] The number of subcarriers included in a PRB is The number of symbols occupied by multi-slot PUSCH in the reference slot is So and The product of can be considered as the total number of REs in a PRB occupied by PUSCHs in multiple slots in the reference slot.

[0179] The PUSCH in multiple slots occupies one PRB and needs to occupy RE carries DMRS, and one PRB occupied by PUSCH in multiple slots also needs to be occupied in the reference slot. REs are used for additional overhead, so you can and Subtract the product of and Get the number of available REs in a reference slot for a PRB occupied by a multi-slot PUSCH.

[0184] The reference slot may be a slot determined according to a preset rule or a slot configured by a network device for a user terminal. The determination of whether a PRB occupied by a multi-slot PUSCH carries data in multiple slots may be based on whether a PRB occupied by a multi-slot PUSCH carries data in the reference slot.

The number of available REs N′ of the multiple PRBs occupied by the multi-slot PUSCH in a unit time can be determined RE .

[0202] The multi-slot PUSCH occupies multiple slots in the time domain and multiple PRBs in the frequency domain. Each time domain contains n symbols. For example, in a slot, the multi-slot PUSCH can occupy n1 symbols. Each PRB contains n2 subcarriers. Therefore, a PRB occupied by the multi-slot PUSCH contains a total of n1*n2 REs within a slot.

[0203] In an optional implementation manner, n=14, and the multi-slot PUSCH occupies the first 12 symbols in one slot, then n1=12, n2=12.

[0204] Furthermore, since the multi-slot PUSCH needs to carry some information other than data, for example, it needs to carry DMRS. This results in the need to occupy some REs in the multi-slot PUSCH. Therefore, based on the time-frequency resources occupied by the multi-slot PUSCH, the number of available REs N′ in the unit time length of the multiple PRBs occupied by the multi-slot PUSCH can be determined. RE Then according to N′ RE The number of REs that can be used to carry data in the entire multi-slot PUSCH is determined based on the number of unit durations included in the multi-slot PUSCH.

[0205] An upper limit value of available resource particles may also be preset, and the upper limit value of available resource particles may be the maximum number of resource particles that can be used when transmitting data and is determined based on a reference bandwidth.

[0206] For example, the upper limit of available resource particles may be the number of available REs in one slot when a multi-slot PUSCH occupies the reference bandwidth. For another example, if a multi-slot PUSCH occupies N slots, the upper limit of available resource particles may be the number of available REs in the N slots of the reference bandwidth.

REs are used for additional overhead, so you can and Based on the product of and Get the number of available REs in a reference slot for a PRB occupied by a multi-slot PUSCH.

[0220] The number of PRBs occupied by multi-slot PUSCH is n PRB , so we can With n PRB The product of is the number of available REs in the reference slot for multiple PRBs occupied by the multi-slot PUSCH.

Therefore, one PRB occupied by multiple slots of PUSCH is included in one symbol, and the total number of REs is use minus and The number of available REs in one symbol of a PRB occupied by a multi-slot PUSCH can be obtained.

[0232] Furthermore, the PUSCH of multiple slots occupies n PRB PRBs, so we can With n PRB The product of the number of available resource elements N′ in a symbol of multiple PRBs occupied by the multi-slot PUSCHRE .

[0236] The multi-slot PUSCH occupies multiple slots in the time domain and multiple PRBs in the frequency domain. Each time domain contains n symbols. For example, in a slot, the multi-slot PUSCH can occupy n1 symbols. Each PRB contains n2 subcarriers. Therefore, a PRB occupied by the multi-slot PUSCH in a slot contains a total of n1*n2 REs.

[0237] In an optional implementation manner, n=14, and the multi-slot PUSCH occupies the first 12 symbols in one slot, then n1=12, n2=12.

[0238] Furthermore, since the multi-slot PUSCH needs to carry some information other than data, for example, it needs to carry DMRS. This results in the need to occupy some REs in the multi-slot PUSCH. Therefore, based on the time-frequency resources occupied by the multi-slot PUSCH, the number of available REs N′ remaining in the multiple PRBs occupied by the multi-slot PUSCH in multiple slots can be determined. RE In this embodiment, N′ RE It is the number of REs that can be used to carry data in the entire multi-slot PUSCH.

[0239] An upper limit value of available resource particles may also be preset, and the upper limit value of available resource particles may be the maximum number of resource particles that can be used when transmitting data and is determined based on a reference bandwidth.

[0240] For example, the upper limit of available resource particles may be the number of available resource particles in one slot when a multi-slot PUSCH occupies the reference bandwidth. For another example, if a multi-slot PUSCH occupies N slots, the upper limit of available resource particles may be the number of available resource particles in the N slots of the reference bandwidth.

[0241] The determined N′ can be RE The smaller value among the upper limit values ​​of available resource particles is used as the number of available REs N for multi-slot PUSCH RE In this implementation, the maximum number of resource elements that can be carried by the multi-slot PUSCH and does not exceed the reference bandwidth carrying upper limit can be determined, thereby making full use of the multi-slot PUSCH for data transmission.

[0242] Specifically, the number of available resource particles N for multi-slot PUSCH RE for:

[0243] N RE =min(N′ RE , preset upper limit of available resource particles)

[0244] In an optional implementation, the number of physical resource blocks n occupied by the multi-slot PUSCH can be PRB , the number of subcarriers included in a physical resource block The total number of symbols occupied by multi-slot PUSCH in multiple time slots The number of resource elements used by multiple physical resource blocks occupied by multi-slot PUSCH to carry demodulation reference signals in multiple time slots The number of resource elements used for additional overhead in multiple physical resource blocks occupied by multi-slot PUSCH in multiple time slots Determine the number of available resource particles N' in multiple physical resource blocks occupied by multi-slot PUSCH in multiple time slots RE .

[0245] In one embodiment, the number of available resource particles N′ RE for:

[0246]

[0247] Among them, the PUSCH of multiple slots occupies n in the frequency domain. PRB PRBs, and each PRB includes Subcarrier, multiple slots of PUSCH are shared in the time domain symbols, so The total number of REs in multiple slots of PRBs occupied by multi-slot PUSCH.

[0248] In the multi-slot PUSCH, it is necessary to occupy Each RE carries information other than data, so it can be used in Based on these and Get the number of available REs N' for PUSCH in multiple slots RE .

[0249] In another embodiment, the above formula Replace with Indicates the number of REs used for additional overhead in multiple slots of a PRB occupied by multi-slot PUSCH.

[0250] Number of available resource particles N′ RE for:

[0251]

[0252] It is the total number of REs used for additional overhead in the multi-slot PUSCH.

[0253] In another embodiment, the above formula Replace with Number of available resource particles N′ RE for:

[0254]

[0255] Here, s is a predefined value, for example, it may be the number of slots occupied by a multi-slot PUSCH, or another example, it may be a value configured in the RRC configuration information, or another example, it may be a scaling parameter indicated by the DCI.

[0256] In other embodiments, based on the above embodiments, Replace with in Indicates the number of REs used to carry DMRS in multiple slots of a PRB occupied by multi-slot PUSCH.

[0257] In an optional implementation, the reference time slot is a predefined time slot.

[0258] The predefined time slot may be the jth time slot among the time slots occupied by the multi-slot PUSCH, where 1≤j≤J, J is the number of time slots occupied by the multi-slot PUSCH, and j is an integer. For example, a fixed value j=1 may be pre-set, and the user terminal may use the first time slot occupied by the multi-slot PUSCH as the reference time slot.

[0259] In an optional embodiment, the predefined time slot may be the time slot with the largest or smallest number of symbols used to carry data among the time slots occupied by the multi-slot PUSCH. For example, the user terminal may determine, based on control information or configuration information of the network device, which symbols are required to carry data when transmitting data on the multi-slot PUSCH. The user terminal may then determine the time slot with the largest or smallest number of symbols used to carry data and use this time slot as the reference time slot.

[0260] In an optional embodiment, among the time slots occupied by the multi-slot PUSCH, the time slot with the largest number of symbols used to carry a demodulation reference signal (DMRS) is selected. For example, the user terminal may determine, based on control information or configuration information of a network device, which symbols need to carry DMRS when transmitting data on the multi-slot PUSCH, and may further determine the time slot with the largest or smallest number of symbols used to carry DMRS, and use this time slot as the reference time slot.

[0261] In an optional implementation manner, the user terminal may also determine a virtual time slot according to the time slots occupied by the multi-slot PUSCH.

[0262] In an optional embodiment, the number of symbols occupied by the multi-slot PUSCH in the virtual time slot is the average number of symbols occupied by the multi-slot PUSCH in the multiple time slots occupied; and / or the number of resource elements used in the virtual time slot to carry the demodulation reference signal of the multi-slot PUSCH is the average number of resource elements used to carry the DMRS of the multi-slot PUSCH in the multiple time slots occupied by the multi-slot PUSCH.

[0263] In an optional implementation, a definition method of the reference time slot may be set and written into the user terminal, so that the user terminal can determine the reference time slot by itself.

[0264] In an optional implementation, the reference time slot may be indicated in the control information sent by the network device to the user terminal. For example, a variable may be set in the control information, and the value of the variable is used to indicate the sequence number of the reference time slot.

[0265] In an optional implementation manner, the reference time slot may also be a time slot configured by higher layer signaling.

[0266] In an optional implementation manner, the preset upper limit value of available resource particles is the product of the number of physical resource blocks of the reference bandwidth and a preset value.

[0267] In an optional implementation manner, the preset value is used to represent the maximum number of available resource particles in a physical resource block in a slot in the reference bandwidth for carrying uplink data.

[0268] Specifically, the reference bandwidth may be, for example, a carrier bandwidth.

[0269] Furthermore, the reference bandwidth may also be the bandwidth of the bandwidth part (BWP) where the user terminal sends a multi-slot PUSCH. The bandwidth of the BWP may be considered as the maximum possible bandwidth occupied by the UE sending a multi-slot PUSCH in the BWP.

[0270] In actual application, the reference bandwidth may also be the maximum bandwidth that can be scheduled when the user terminal transmits multiple slots of PUSCH in one slot.

[0271] In the solution of the present application, the overall transport block size can be limited by referring to the carrying capacity of the bandwidth.

[0272] In current user terminals, only PUSCH transmission in one slot needs to be considered. Therefore, preferably, the size of the buffer can be determined according to the maximum number of transmission bits of the user terminal in one slot. Therefore, existing user terminals often have The buffering capacity of the TBS corresponding to each RE is determined by the following formula: When the user terminal supports the "multi-slot PUSCH transmission of one TB" technology, this solution limits the TBS to no more than the TBS of "one slot PUSCH transmission". On the one hand, there is no need to re-develop the user terminal's buffer size, especially without increasing the buffer size and thus increasing the user terminal cost. On the other hand, "multi-slot PUSCH transmission of one TB" is often used in coverage-limited scenarios. In such cases, the user terminal does not usually need to transmit a large TB, so this limitation does not adversely affect the user terminal's transmission performance.

[0273] In an optional implementation, the reference bandwidth is the bandwidth occupied by the multi-slot PUSCH.

[0274] In an optional implementation manner, the preset value is used to represent the maximum number of available resource elements for carrying uplink data in the maximum number of time slots occupied by the multi-slot PUSCH in a physical resource block.

[0275] For example, the optional values ​​of the number of time slots occupied by multi-slot PUSCH are {2, 4, 8, ..., Kmax}, then the maximum number of time slots is K max When the multi-slot PUSCH is transmitted with the maximum number of slots, the number of symbols used to carry data is recorded as L max For example, assuming that the number of symbols carrying data in each time slot is the same, which is l, then L max =l·K max ; A PRB includes n2 subcarriers, then the preset value can be equal to L max The product of n2 is the maximum number of time slots K occupied by the multi-slot PUSCH in a physical resource block. max The maximum number of available resource particles used to carry uplink data.

[0276] This application also provides another communication method, including:

[0277] Receiving a transport block sent by a user terminal via a multi-slot physical uplink shared channel (PUSCH); wherein the coding block is obtained by encoding the transport block, and the size of the transport block is determined according to the time-frequency resources of the multi-slot PUSCH;

[0278] The time-frequency resources occupied by the multi-slot PUSCH include time-frequency resources in multiple time slots.

[0279] This method can be executed by a network device. The user terminal can determine the transport block size based on any of the above implementation methods, obtain a transport block of the corresponding size, and then encode it to obtain a coded block. The user terminal can send the coded block through a multi-slot PUSCH.

[0280] After receiving the coded block, the network device may process the received coded block, for example, it may decode the coded block to obtain the transport block therein.

[0281] In an optional implementation, when decoding a received coded block, the network device may first determine a transport block size TBS, and then decode the coded block according to the TBS.

[0282] In one implementation, the TBS determined by the network device may be any of the following TBSs.

[0283] In one embodiment, the network device may determine the TBS in the same manner as the user terminal to which the coding block is sent. The user terminal may determine the TBS in the same manner as the user terminal to which the coding block is sent.
