[0136] The following is an explanation and interpretation of the terminology used in this disclosure.
[0137] I. Time-domain resources of PUSCH.
[0138] Network devices configure time-domain resources for terminals to send PUSCH, including: the time slot for sending PUSCH, the number of symbols for PUSCH, and the start symbol for PUSCH within the time slot. Based on these parameters, the terminal can uniquely determine the time-domain resources for sending PUSCH, and the network device will also receive the PUSCH sent by the terminal on those time-domain resources.
[0139] In some embodiments, the network device can configure the slot offset, start symbol, and allocation length for the terminal to send PUSCH. The slot offset is represented by parameter k2, the start symbol by parameter S, and the allocation length by parameter L.
[0140] In some embodiments, k2 indicates the starting time slot configured for PUSCH, S indicates the starting symbol configured for PUSCH, and L indicates the number of symbols configured for PUSCH. The value of S is the symbol index of the starting symbol within a time slot, with the symbol index starting from 0. A symbol index of 0 corresponds to the first symbol in the time slot, and so on, until the last symbol of the time slot. In some embodiments, S and L can be replaced by a start and length indicator value (SLIV), which is determined based on S and L, as follows:
[0141] If (L-1)≤7, then SLIV=14×(L-1)+S;
[0142] Otherwise, SLIV = 14 × (14 - L + 1) + (14 - 1 - S), where 0 <L≤14-S。
[0143] In some embodiments, Figure 1B is a schematic diagram of the time domain resources of a single-slot PUSCH. As shown in Figure 1B, k2=3, S=2, L=10, k2 indicates that the starting time slot of the PUSCH is uplink time slot #3, S indicates that the starting symbol of the PUSCH is the 3rd symbol in the time slot, and L indicates that the number of symbols of the PUSCH is 10. Then, the time domain resources of the PUSCH configured by the network device for the terminal are 10 consecutive symbols starting from the 3rd symbol in time slot #3.
[0144] In some embodiments, all symbols in the downlink slot of Figure 1B are downlink symbols, all symbols in the uplink slot are uplink symbols, the first 8 symbols in the special slot are downlink symbols, the last 2 symbols are uplink symbols, and the remaining symbols are flexible symbols.
[0145] II. PUSCH mapping type
[0146] PUSCH supports two mapping types: PUSCH mapping type A and PUSCH mapping type B. The two mapping types have different restrictions on S and L, as well as S plus L. Table 1 shows the PUSCH mapping types. As shown in Table 1, for PUSCH mapping type A, only the starting symbol of the PUSCH is allowed to be the first symbol of the time slot, and the time-domain resources of the PUSCH are not allowed to cross time slot boundaries. For PUSCH mapping type B, the starting symbol of the PUSCH is allowed to be any symbol of the time slot.
[0147] Table 1
[0148] III. PUSCH repetition type
[0149] PUSCH supports repetition, including two repetition types: PUSCH repetition type A and PUSCH repetition type B. PUSCH repetition type A is slot-level repetition, where each slot uses the same symbol allocation, meaning the start symbol S and length L are identical. PUSCH repetition type B is mini-slot-level or symbol-level repetition. For PUSCH repetition type A, time-domain resources of PUSCH are not allowed to cross slot boundaries; for PUSCH repetition type B, time-domain resources of PUSCH are allowed to cross slot boundaries, but not consecutively across two slot boundaries.
[0150] In some embodiments, for PUSCH repetition type A, when the network device configures the terminal's PUSCH repetition type to PUSCH repetition type A through higher-layer parameters, the terminal sends PUSCH using PUSCH repetition type A. The network device indicates the repetition number of the backup PUSCH, represented by the parameter K. The K repetitions are sequentially allocated across K time slots, and the K time slots use the same symbol allocation, i.e., the symbol on each time slot is determined according to S and L (or SLIV).
[0151] In some embodiments, the determination of the K time slots is divided into two methods: physical time slot counting and available time slot counting.
[0152] In some embodiments, the physical time slot count refers to K consecutive time slots starting from the time slot indicated by k2. In some embodiments, subject to conflict criteria, not all K time slots may be used to transmit PUSCH. For example, if the symbols indicated by S and L (or SLIV) in one of the K time slots include downlink symbols, synchronization signal block (SSB) symbols, or sounding reference signal (SRS) symbols, then PUSCH cannot be transmitted in that time slot.
[0153] In some embodiments, available time slot counting refers to checking each time slot one by one, starting from the time slot indicated by k2, until K time slots that can be used to transmit PUSCH are found. A time slot that can be used to transmit PUSCH is a time slot within a time slot whose symbols indicated by S and L (or SLIV) do not include downlink symbols, SSB symbols, or SRS symbols. A time slot that cannot be used to transmit PUSCH is a time slot within a time slot whose symbols indicated by S and L (or SLIV) include downlink symbols, SSB symbols, or SRS symbols.
[0154] In one example, Figure 1C is a time-domain resource diagram of PUSCH repetition type A based on physical time slot count, where k2=3, S=2, L=10, and K=4. As shown in Figure 1C, time slots #3 to #6 are allocated to PUSCH repetition type A. In time slots #3 and #4, the symbols indicated by S and L (or SLIV) do not include downlink symbols, SSB symbols, or SRS symbols. In time slots #5 and #6, the symbols indicated by S and L (or SLIV) include downlink symbols. Therefore, the terminal device will send PUSCH in time slots #3 and #4, but will not send PUSCH in time slots #5 and #6.
[0155] In one example, Figure 1D is a temporal resource diagram of PUSCH repetition type A based on available time slot counts. The values of parameters k2, S, L, and K are the same as in Figure 1C. As shown in Figure 1D, starting from time slot #3, the first four time slots (excluding downlink symbols, SSB symbols, or SRS symbols) indicated by S and L (or SLIV) are time slots #3, #4, #8, and #9, respectively. Therefore, the terminal device will transmit PUSCH on these four time slots.
[0156] In some embodiments, for PUSCH repetition type B, when the network device configures the terminal's PUSCH repetition type to PUSCH repetition type B through higher-layer parameters, the terminal sends PUSCH using PUSCH repetition type B. The network device will indicate the terminal device to the number of repetitions K. The time-domain resource allocation for PUSCH repetition type B consists of two steps: first, determining the nominal repetition; second, determining the actual repetition.
[0157] In some embodiments, the number of nominal repetitions is K, each nominal repetition includes L consecutive symbols, the starting symbol of the first nominal repetition is the symbol indicated by S in the time slot indicated by k2, the second nominal repetition is the symbol following the last symbol of the first nominal repetition, and so on.
[0158] In some embodiments, a nominal repeat includes at least one actual repeat, each actual repeat being a consecutive set of all valid symbols available for transmission of PUSCH within a time slot, wherein valid symbols are symbols other than invalid symbols, including downlink symbols, SSB symbols, SRS symbols, symbols indicated by higher-layer signaling, etc. If an actual repeat includes only one symbol, then that actual repeat is ignored.
[0159] In some embodiments, PUSCH repeat type B can only use PUSCH mapping type B, so only S and L can be used to indicate time-domain resources, and SLIV cannot be used to indicate time-domain resources.
[0160] In some embodiments, Figure 1E is a time-domain resource diagram of PUSCH repetition type B, where k2 = 3, S = 12, L = 4, and K = 4. As shown in Figure 1E, the PUSCH includes 4 nominal repetitions, each of which includes 4 symbols. The 4 nominal repetitions are contiguous in the time domain. Due to the crossing of time slot boundaries, nominal repetition #0 includes two actual repetitions (actual repetition #0 and actual repetition #1). Actual repetition #0 includes the 13th and 14th symbols located in time slot #3, and actual repetition #1 includes the 1st and 2nd symbols located in time slot #4. Since the 4th and 9th symbols in time slot #4 are invalid symbols, and the number of symbols in an actual repetition must be greater than 1, nominal repetition #1 includes one actual repetition (actual repetition #2), which includes the 5th and 6th symbols located in time slot #4. Nominal repetition #2 includes one actual repetition (actual repetition #3), which includes the 7th and 8th symbols located in time slot #4. Since there are no invalid symbols and it does not cross the time slot boundary, nominal repetition #3 is an actual repetition (actual repetition #4), which includes the 14th symbol of the 11th symbol value located in time slot #4.
[0161] IV. Transport block processing over multiple slots (TBoMS)
[0162] PUSCH supports TBoMS. For single-slot PUSCH and PUSCH repetition type A, one time slot processes one transport block (TB). The transport block size (TBS) is determined based on the time-domain resources on one time slot. The TB will be transmitted on one time slot (i.e., single-slot PUSCH), or the TB will be transmitted repeatedly on K time slots (i.e., PUSCH repetition type A). For TBoMS, multiple time slots process one TB. The TBS is determined based on the time-domain resources on multiple time slots, and the TB will be transmitted on these multiple time slots. Therefore, the network device will notify the terminal of the number of time slots N for TBoMS. The terminal will determine the TBS based on the time-domain resources on N time slots and complete the transmission of the TB on N time slots.
[0163] In some embodiments, the time-domain resource allocation method of TBoMS (including N time slots and symbol allocation within each time slot) is the same as the time-domain resource allocation method of PUSCH repetition type A, but only the available time slot count can be used. TBoMS can be used in combination with PUSCH repetition type A. When TBoMS and PUSCH repetition type A are used in combination, the terminal determines N×K time slots according to the available time slot count method, where K groups of N time slots represent K repetitions of one TBoMS.
[0164] In one example, Figure 1F is a schematic diagram of the time-domain resources combining TBoMS and PUSCH repetition type A, where k2 = 3, N = 2, K = 2, S = 2, and L = 10. According to the time-domain resource allocation method of PUSCH repetition type A, TBoMS uses the same symbol allocation in each time slot, i.e., the 3rd to 12th symbols of each time slot; according to the available time slot counting method, TBoMS is allocated in time slots #3, #4, #8, and #9, with the first TBoMS repetition allocated to time slots #3 and #4, and the second TBoMS repetition allocated to time slots #8 and #9.
[0165] In some embodiments, in order to support flexible time domain resource allocation without incurring a large amount of signaling overhead, the time domain resources for sending PUSCH can be indicated by a "time domain resource allocation (TDRA) table + row index".
[0166] In some embodiments, the network device configures a TDRA table for the terminal via higher-layer signaling, or the terminal device uses the default TDRA table.
[0167] In some embodiments, the TDRA table includes at least one row, each row corresponding to a candidate value of a PUSCH mapping type, a candidate value of k2, a candidate value of S, a candidate value of L, a candidate value of SLIV, a candidate value of K, and / or a candidate value of N.
[0168] In some embodiments, the network device notifies the terminal of a row index that indicates a row in the TDRA table. The terminal uses the candidate values of the PUSCH mapping type corresponding to that row, the candidate values of k2, S, L, K, and N to determine the time domain resources for sending PUSCH.
[0169] In some embodiments, a row in the TDRA table does not necessarily need to include all parameters (PUSCH mapping type, k2, S, L, SLIV, K, N); these parameters are optional. In one example, for a single-slot PUSCH, K and N may not be configured. In one example, if it is not a TBoMS, N may not be configured. In one example, for repeating type B, SLIV may not be configured. In one example, if SLIV is used, S and L may not be configured.
[0170] In some embodiments, a row in the TDRA table may include multiple sets of parameters, each set including at least one of the following: PUSCH mapping type, k2, S, L, SLIV, K, N. In this case, multiple PUSCHs (Multi-PUSCHs, Multiple PUSCHs) can be scheduled at once, and each PUSCH uses one of the sets of parameters to determine the time-domain resources. The number of PUSCHs is equal to the number of SLIVs, or the number of sets of S and L.
[0171] In some embodiments, multiple PUSCH scheduling does not support PUSCH duplication. If the higher-layer signaling is configured with K greater than 1, then K is assumed to be equal to 1; or, if a row in the TDRA table includes multiple SLIVs and multiple Ks, and at least one K is greater than 1, then all Ks greater than 1 are assumed to be 1.
[0172] In one example, Figures 1G and 1H illustrate time-domain resource scheduling for multiple PUSCHs. In Figure 1G, assuming a row in the TDRA table includes a k2 and two SLIVs, with the two SLIVs corresponding to the first 7 symbols and the last 7 symbols of slot #4 respectively, then this row schedules two PUSCHs. The first PUSCH is allocated to the first 7 symbols of the slot indicated by k2, and the second PUSCH is allocated to the last 7 symbols of the slot indicated by k2. In Figure 1H, assuming a row in the TDRA table includes two k2s and two SLIVs, the first k2 and the first SLIV indicate that the first PUSCH is allocated to all symbols of slot #3, and the second k2 and the second SLIV indicate that the second PUSCH is allocated to all symbols of slot #4.
[0173] V. TBS Calculation
[0174] The process of TBS calculation is as follows:
[0175] Step 1: Determine the number N of REs used for PUSCH transmission within a time slot. RE .
[0176] Step 1-1: Determine the number N′ of resource elements (REs) within a physical resource block (PRB) allocated to PUSCH. RE , in The number of subcarriers included in a PRB. The number of symbols L allocated to PUSCH, This refers to the number of REs (Remote Elements) occupied by the code division multiplexing (CDM) blocks in each PRB (Programmable Block) corresponding to L symbols, excluding the data in the demodulation reference signal (DMRS). The overhead of configuring higher-level signaling. For PUSCH repetition type B, It is determined by the nominal repetition of L symbols.
[0177] Steps 1-2, determine N RE If TBoMS is configured, then N RE =N·min(156,N′) RE )·n PRB , where n PRB N is the number of PRBs allocated to PUSCH, and N is the number of time slots in TBoMS. Otherwise, N RE =min(156,N′) RE )·n PRB .
[0178] Step 2: Calculate the non-quantified intermediate variable N info =N RE ·R·Q m ·v, where R is the target code rate of PDSCH, and Q m v represents the modulation order of the PDSCH, and v represents the layer number of the PDSCH.
[0179] Step 3: If N info If the value is ≤3824, perform the following steps: Calculate the intermediate variables for quantification. in, Based on Table 2, find the value of N not less than N. i ′ nfo The minimum value is taken as TBS. Table 2 shows N. info ≤3824 TBS.

[0183] if in,

[0186] otherwise,
[0187] VI. Transmission Occasion (TO)
[0188] The transmission timing of PUSCH is defined as a slot index within the system frame corresponding to system frame number (SFN) #SFN. Time slot index The first symbol S in the corresponding time slot, and the number of consecutive symbols L. For PUSCH repetition type B, a PUSCH transmission timing is defined as a nominal repetition.
[0189] In some embodiments, the symbol allocation for each time slot is currently the same for the time domain resource allocation of PUSCH. This reduces the flexibility of time domain resource allocation, wastes some uplink resources, and thus affects uplink coverage performance.
[0190] This disclosure provides a communication method, communication device, communication system, storage medium, and program product. Based on the temporal resource configuration of a first data transmission, the symbols for the first data transmission are determined.

[0199] In some embodiments, when the first data transmission is an SRS transmission, the first type of symbols are symbols not used for SRS transmission. In one example, the first type of symbols includes at least one of the following: downlink symbols, PUSCH symbols, SSB symbols, symbols indicating higher-layer signaling, etc.
[0200] The communication method of this disclosure embodiment is described below using PUSCH as an example of the first data transmission.
[0201] Figure 2A is an interactive schematic diagram of a communication method provided according to an embodiment of the present disclosure. As shown in Figure 2A, the present disclosure relates to a communication method. Executed by a communication system 100, the communication method includes steps S2101 to S2106.

In one example, the first information indicates k2 and SLIV. In another example, the first information indicates k2, SLIV, and K. In yet another example, the first information indicates k2, S, and L. In yet another example, the first information indicates k2, S, L, and K.
[0216] In step S2102, the terminal determines the symbol of PUSCH based on the first information.
[0217] In some embodiments, the terminal determines the starting time slot, the starting symbol, and the number of symbols of the PUSCH based on the first information, and determines the number of symbols of the PUSCH based on the starting time slot, the starting symbol, and the number of symbols of the PUSCH.
[0218] In some embodiments, the first information indicates k2, S, and L. The terminal determines the starting time slot of the PUSCH based on k2, the starting symbol of the PUSCH based on S, and the number of symbols of the PUSCH based on L.
[0219] In some embodiments, the first information indicates k2 and SLIV, and the terminal determines the starting time slot of the PUSCH based on k2 and the starting symbol and number of symbols of the PUSCH based on SLIV.
[0220] In some embodiments, the terminal starts from the start symbol in the start time slot, determines the symbols that satisfy the first condition as PUSCH symbols, and determines the symbols that do not satisfy the first condition as PUSCH symbols.
[0221] In some embodiments, the terminal starts from the starting symbol in the starting time slot, traverses each symbol sequentially, and determines the symbols that meet the first condition as PUSCH symbols until the number of PUSCH symbols is L (denoted as Method 1).
[0222] In some embodiments, the terminal starts from the starting symbol in the starting time slot, traverses each symbol in the starting time slot in turn, and determines the symbol that satisfies the first condition as the symbol of PUSCH until the last symbol in the starting time slot (denoted as method 2-1).
[0223] In some embodiments, the terminal starts from the starting symbol in the starting time slot, traverses each symbol in the starting time slot in turn, and determines the symbols that meet the first condition as PUSCH symbols until the number of PUSCH symbols is L (denoted as method 2-2).
[0224] In some embodiments, for method 1, the symbols of the PUSCH determined by the terminal can be located in the same time slot or in different time slots, that is, method 1 supports PUSCH symbols spanning time slots. For method 2 (including method 2-1 and method 2-2), the symbols of the PUSCH determined by the terminal are located in the same time slot, that is, method 2 supports PUSCH symbols within one time slot.
[0225] In some embodiments, for method 1, the number of symbols for the PUSCH determined by the terminal is equal to the number of symbols for the PUSCH indicated by the first information. For method 2, the number of symbols for the PUSCH determined by the terminal is less than or equal to the number of symbols for the PUSCH indicated by the first information.
[0226] In one example, taking method 1 as an example, Figure 2B is a schematic diagram of the time-domain resources of the PUSCH determined based on method 1. As shown in Figure 2B, k2 indicates the starting time slot as uplink time slot #3, S indicates the starting symbol as the first symbol, and L indicates the number of symbols as 8. The terminal starts from the first symbol in uplink time slot #3 and traverses each symbol in turn. Since the third to sixth symbols and the ninth to twelfth symbols in uplink time slot #3 are first-class symbols, these symbols are not determined as PUSCH symbols. Instead, the first to second symbols, the seventh to eighth symbols, the thirteenth to fourteenth symbols in uplink time slot #3, and the first to second symbols in uplink time slot #4, a total of 8 symbols, are determined as PUSCH symbols.
[0227] In one example, taking method 2-1 as an example, Figure 2C is a schematic diagram of the time-domain resources of the PUSCH determined based on method 2-1. As shown in Figure 2C, k2 indicates the starting time slot as uplink time slot #3, S indicates the starting symbol as the first symbol, and L indicates the number of symbols as 8. The terminal starts from the first symbol in uplink time slot #3 and traverses each symbol in uplink time slot #3 in sequence. Since the third to sixth symbols and the ninth to twelfth symbols in uplink time slot #3 are first-class symbols, these symbols are not determined as PUSCH symbols. Instead, the first to second symbols, the seventh to eighth symbols, and the thirteenth to fourteenth symbols in uplink time slot #3, a total of 6 symbols, are determined as PUSCH symbols.
[0228] In one example, taking method 2-2 as an example, Figure 2D is a schematic diagram of the time-domain resources of PUSCH determined based on method 2-2. As shown in Figure 2D, k2 indicates the starting time slot as uplink time slot #3, S indicates the starting symbol as the first symbol, and L indicates the number of symbols as 4. The terminal starts from the first symbol in uplink time slot #3 and traverses each symbol in uplink time slot #3 in sequence. Since the third to sixth symbols and the ninth to twelfth symbols in uplink time slot #3 are first-class symbols, these symbols are not determined as PUSCH symbols. Instead, the first to second symbols and the seventh to eighth symbols in uplink time slot #3, a total of 4 symbols, are determined as PUSCH symbols.
[0229] In some embodiments, the terminal determines the starting time slot of the PUSCH, the starting symbol of the PUSCH, the number of symbols of the PUSCH, and the number of repetitions of the PUSCH based on the first information, and determines the symbol of the PUSCH based on the starting time slot of the PUSCH, the starting symbol of the PUSCH, the number of symbols of the PUSCH, and the number of repetitions of the PUSCH.
[0230] In some embodiments, the first information indicates k2, S, L and K, and the terminal determines the starting time slot of PUSCH according to k2, the starting symbol of PUSCH according to S, the number of symbols of PUSCH according to L, and the number of repetitions of PUSCH according to K.
[0231] In some embodiments, the first information indicates k2, SLIV, and K. The terminal determines the starting time slot of the PUSCH based on k2, the starting symbol and the number of symbols of the PUSCH based on SLIV, and the number of repetitions of the PUSCH based on K.
[0232] In some embodiments, for the first repetition of PUSCH repetition type A, the terminal may use method 1, method 2-1, and method 2-2 to determine the symbol of the first repetition. Specific implementation details can be found in the embodiments of method 1, method 2-1, and method 2-2, and will not be elaborated here.
[0233] In some embodiments, for the i-th repetition of PUSCH repetition type A, the terminal starts from the starting symbol in the reference time slot corresponding to the i-th repetition, traverses each symbol sequentially, and determines the symbol that satisfies the first condition as the symbol of the i-th repetition, until the number of symbols in the i-th repetition is L (denoted as method 3). Where i = 2, 3, ..., K.
[0234] In some embodiments, for the i-th repetition of PUSCH repetition type A, the terminal starts from the first symbol in the reference time slot corresponding to the i-th repetition, sequentially traverses each symbol in the reference time slot, and determines the symbol that satisfies the first condition as the symbol of the i-th repetition, until the last symbol in the reference time slot (denoted as method 4-1). Where i = 2, 3, ..., K.
[0235] In some embodiments, for the i-th repetition of PUSCH repetition type A, the terminal starts from the starting symbol in the reference time slot corresponding to the i-th repetition, and sequentially traverses each symbol in the reference time slot, determining the symbol that satisfies the first condition as the symbol of the i-th repetition, until the number of symbols in the i-th repetition is L (denoted as method 4-2). Where i = 2, 3, ..., K.
[0236] In some embodiments, for method 3, the i-th repeating symbol determined by the terminal can be located in the same time slot or in different time slots, that is, method 3 supports the i-th repeating symbol spanning time slots. For method 4 (including method 4-1 and method 4-2), the i-th repeating symbol determined by the terminal is located in the same time slot, that is, method 4 supports the i-th repeating symbol being in one time slot.
[0237] In some embodiments, for method 3, the number of symbols in the i-th repetition determined by the terminal is equal to the number of symbols indicated by the first information. For method 4, the number of symbols in the i-th repetition determined by the terminal is less than or equal to the number of symbols indicated by the first information.
[0238] In some embodiments, the reference time slot corresponding to the i-th repetition of PUSCH repetition type A is the time slot where the end symbol of the (i-1)-th repetition is located (denoted as method A-1).
[0239] In some embodiments, the reference time slot corresponding to the i-th repetition of PUSCH repetition type A is the time slot following the time slot of the end symbol of the (i-1)-th repetition (denoted as method A-2).
[0240] In some embodiments, for method A-1, when the terminal determines the symbol of the i-th repetition starting from the start symbol in the time slot where the end symbol of the (i-1)-th repetition is located, the first type of symbol also includes: the symbol of the (i-1)-th repetition. That is, when the terminal adopts method A-1, it should avoid the overlap between the symbol of the i-th repetition and the symbol of the (i-1)-th repetition.
[0241] In some embodiments, the terminal may use method A-1 or method A-2 to determine the reference time slot corresponding to the i-th repetition. In some embodiments, the terminal may determine to use method A-1 or method A-2 based on its own implementation, based on the instruction of the network device, or based on the protocol specification.
[0242] In some embodiments, if the end symbol of the (i-1)th repetition precedes the start symbol of the i-th repetition, the terminal determines the reference time slot corresponding to the i-th repetition based on method A-1. If the end symbol of the (i-1)th repetition overlaps with the start symbol of the i-th repetition, the terminal determines the reference time slot corresponding to the i-th repetition based on method A-2. If the end symbol of the (i-1)th repetition follows the start symbol of the i-th repetition, the terminal determines the reference time slot corresponding to the i-th repetition based on method A-2.
[0243] In some embodiments, for method 4-1 or method 4-1, the terminal can determine the reference time slot corresponding to the i-th repetition based on method A-2, where i = 2, 3, ..., K.
[0244] In some embodiments, for method 4-1 or method 4-2, the terminal may determine each time slot of each repetition (including the first repetition and the i-th repetition) based on the physical time slot count or the available time slot count, and determine the symbol of each repetition within each time slot based on method 4-1 or method 4-2.
[0245] In one example, taking method 3 and method A-1 as examples, Figure 2E is a schematic diagram of the time-domain resources of PUSCH repetition type A determined based on method 3 and method A-1. As shown in Figure 2E, k2 indicates the starting time slot as uplink time slot #2, S indicates the starting symbol as the third symbol, L indicates the number of symbols as 6, and K indicates the number of repetitions as 2. For the first repetition (i.e., repetition #0 in the figure), the terminal starts from the third symbol in uplink time slot #2 and traverses each symbol sequentially. Since the third to sixth symbols and the ninth to twelfth symbols in uplink time slot #2 are first-class symbols, these symbols are not determined as PUSCH symbols. Instead, the seventh to eighth symbols, the thirteenth to fourteenth symbols in uplink time slot #2, and the first to second symbols in uplink time slot #3, a total of 6 symbols, are determined as the symbols of the first repetition of PUSCH repetition type A. For the second repetition (i.e., repetition #1 in the diagram), since the end symbol of the first repetition (i.e., the second symbol in uplink time slot #3) is before the start symbol of the second repetition (i.e., the third symbol in uplink time slot #3), the reference time slot for the second repetition is the time slot where the end symbol of the first repetition is located, i.e., uplink time slot #3. Then, starting from the third symbol in uplink time slot #3, the terminal traverses each symbol in turn, and determines the symbols from the third symbol to the eighth symbol in uplink time slot #3, a total of 6 symbols, as the symbols for the second repetition of PUSCH repetition type A.
[0246] In one example, taking method 3 and method A-2 as examples, Figure 2F is a schematic diagram of the time-domain resources of PUSCH repetition type A determined based on method 3 and method A-2. As shown in Figure 2F, k2 indicates the starting time slot as uplink time slot #2, S indicates the starting symbol as the third symbol, L indicates the number of symbols as 8, and K indicates the number of repetitions as 2. For the first repetition (i.e., repetition #0 in the figure), the terminal starts from the third symbol in uplink time slot #2 and traverses each symbol sequentially. Since the third to sixth symbols and the ninth to twelfth symbols in uplink time slot #2 are first-class symbols, these symbols are not determined as PUSCH symbols. Instead, the seventh to eighth symbols, the thirteenth to fourteenth symbols in uplink time slot #2, and the first to fourth symbols in uplink time slot #3, a total of 8 symbols, are determined as the symbols of the first repetition of PUSCH repetition type A. For the second repetition (i.e., repetition #1 in the diagram), since the end symbol of the first repetition (i.e., the fourth symbol in uplink time slot #3) is after the start symbol of the second repetition (i.e., the third symbol in uplink time slot #3), the reference time slot corresponding to the second repetition is the next time slot after the time slot where the end symbol of the first repetition is located, i.e., uplink time slot #4. Then, starting from the third symbol in uplink time slot #4, the terminal traverses each symbol in turn, and determines the symbols of the second repetition of PUSCH repetition type A from the third symbol to the tenth symbol in uplink time slot #4.
[0247] In one example, taking method 3 and method A-2 as examples, Figure 2G is a schematic diagram of the time-domain resources of PUSCH repetition type A determined based on method 3 and method A-2. As shown in Figure 2G, k2 indicates the starting time slot as uplink time slot #2, S indicates the starting symbol as the third symbol, L indicates the number of symbols as 7, and K indicates the number of repetitions as 2. For the first repetition (i.e., repetition #0 in the figure), the terminal starts from the third symbol in uplink time slot #2 and traverses each symbol sequentially. Since the third to sixth symbols and the ninth to twelfth symbols in uplink time slot #2 are first-class symbols, these symbols are not determined as PUSCH symbols. Instead, the seventh to eighth symbols, the thirteenth to fourteenth symbols in uplink time slot #2, and the first to third symbols in uplink time slot #3, a total of 7 symbols, are determined as the symbols of the first repetition of PUSCH repetition type A. For the second repetition (i.e., repetition #1 in the diagram), since the end symbol of the first repetition (i.e., the third symbol in uplink time slot #3) overlaps with the start symbol of the second repetition (i.e., the third symbol in uplink time slot #3), the reference time slot corresponding to the second repetition is the next time slot after the time slot where the end symbol of the first repetition is located, i.e., uplink time slot #4. Then, starting from the third symbol in uplink time slot #4, the terminal traverses each symbol in turn, and determines the symbols from the third symbol to the ninth symbol in uplink time slot #4, a total of 7 symbols, as the symbols for the second repetition of PUSCH repetition type A.
[0248] In one example, taking method 4 and physical time slot counting as examples, Figure 2H is a schematic diagram of the time domain resources of PUSCH repetition type A determined based on method 4 and physical time slot counting. As shown in Figure 2H, k2 indicates the starting time slot as special time slot #2, S indicates the starting symbol as the ninth symbol, L indicates the number of symbols as 6, and K indicates the number of repetitions as 2. Then, starting from special time slot #2, the terminal determines two consecutive time slots as time slots for two repetitions, namely special time slot #2 and uplink time slot #3. For the first repetition (i.e., repetition #0 in the figure), the terminal starts from the ninth symbol in special time slot #2 and traverses each symbol in special time slot #2 in sequence. Since the ninth and tenth symbols in special time slot #2 are first-class symbols, the ninth and tenth symbols are not determined as PUSCH symbols. Instead, the eleventh to fourteenth symbols in special time slot #2, a total of 4 symbols, are determined as the symbols for the first repetition of PUSCH repetition type A. For the second repetition (i.e. repetition #1 in the diagram), the terminal starts from the ninth symbol in uplink time slot #3 and sequentially traverses each symbol in uplink time slot #3, identifying the ninth to the fourteenth symbols in uplink time slot #3, a total of 6 symbols, as the symbols for the second repetition of PUSCH repetition type A.
[0249] In one example, taking method 4 and available time slot counting as examples, Figure 2I is a schematic diagram of the time domain resources for PUSCH repetition type A determined based on method 4 and available time slot counting. As shown in Figure 2I, k2 indicates the starting time slot as special time slot #2, S indicates the starting symbol as the ninth symbol, L indicates the number of symbols as 6, and K indicates the repetition count as 2. Then, starting from special time slot #2, the terminal judges each time slot one by one until it finds two time slots that can be used to send PUSCH. The time slots that can be used to send PUSCH are the time slots in which the symbols indicated by S and L (or SLIV) do not include the first type of symbols. Since the symbols indicated by S and L in special time slot #2 include the first type of symbols, and the symbols indicated by S and L in uplink time slots #3 and #4 do not include the first type of symbols, the consecutive uplink time slots #3 and #4 are determined as two repetition time slots. For the first repetition (i.e., repetition #0 in the diagram), the terminal starts from the ninth symbol in uplink time slot #3 and sequentially traverses each symbol in uplink time slot #3, identifying the six symbols from the ninth to the fourteenth as the first repetition symbols of PUSCH repetition type A. For the second repetition (i.e., repetition #1 in the diagram), the terminal starts from the ninth symbol in uplink time slot #4 and sequentially traverses each symbol in uplink time slot #4, identifying the six symbols from the ninth to the fourteenth as the second repetition symbols of PUSCH repetition type A.
[0250] In some embodiments, for the first nominal repetition of PUSCH repetition type B, the terminal uses method 1 to determine the symbol of the first nominal repetition. Specific implementation details can be found in the embodiments of method 1, and will not be repeated here.
[0251] In some embodiments, for the i-th nominal repetition of PUSCH repetition type B, the terminal starts from the first symbol after the end symbol of the i-th nominal repetition, traverses each symbol sequentially, and determines the symbol that satisfies the first condition as the symbol of the i-th nominal repetition, until the number of symbols in the i-th nominal repetition is L. Where i = 2, 3, ..., K.
[0252] In some embodiments, for the i-th nominal repetition of PUSCH repetition type B, the terminal starts from the first symbol that satisfies the first condition after the end symbol of the i-th nominal repetition, and sequentially traverses each symbol, determining the symbol that satisfies the first condition as the symbol of the i-th nominal repetition, until the number of symbols in the i-th nominal repetition is L. Where i = 2, 3, ..., K.
[0253] In some embodiments, the terminal may determine the symbol of the K nominal repetitions as the symbol of PUSCH repetition type B (denoted as method B-1).
[0254] In some embodiments, the terminal may determine, based on K nominal repetitions, at least one actual repetition of the symbol included in each nominal repetition.
[0255] In some embodiments, the terminal may determine the actual repeated symbol as a symbol of PUSCH repeat type B.
[0256] In some embodiments, the method for a terminal to determine actual repetitions includes: for each of the K nominal repetitions, each nominal repetition includes at least one actual repetition, each actual repetition being a set of all valid symbols available for transmission of PUSCH within a time slot, wherein valid symbols are symbols other than those of the first type. If an actual repetition includes only one symbol, then that actual repetition is ignored.
[0257] In some embodiments, during the process of determining actual repetitions based on K nominal repetitions, for each nominal repetition that occupies two consecutive time slots, the terminal can divide the nominal repetition into two actual repetitions (denoted as method B-2).
[0258] In some embodiments, during the process of determining actual repetitions based on K nominal repetitions, the terminal determines a nominal repetition that occupies two consecutive time slots within each nominal repetition as a single actual repetition, wherein the symbols included in this single actual repetition are located in different time slots (denoted as Method B-3). In other words, Method B-3 no longer divides nominal repetitions that cross time slot boundaries into two actual repetitions.
[0259] In some embodiments, for method B-1, the terminal can directly send PUSCH based on K nominal repetitions. In this case, it is not necessary to further determine the actual repetitions; that is, rate matching (RM) is performed once for each nominal repetition, and each nominal repetition corresponds to a redundancy version (RV). A bit sequence is selected starting with the RV and mapped to the time-frequency resources of each nominal repetition. In other words, compared with methods B-2 and B-3, method B-1 may perform RM fewer times and has fewer corresponding RVs, thus effectively reducing resource overhead and improving transmission performance.
[0260] In some embodiments, for methods B-2 and B-3, the terminal sends PUSCH based on the actual repetitions included in the K nominal repetitions. In this case, RM is performed once for each actual repetition, and each actual repetition corresponds to a RV. A bit sequence is selected starting with the RV and mapped to the time-frequency resources of each actual repetition. That is, for the actual repetitions included in the nominal repetitions that cross time slot boundaries, method B-3 performs fewer RM operations and has fewer corresponding RVs compared to method B-2, thus effectively reducing resource overhead and improving transmission performance.
[0261] In one example, taking method B-1 as an example, Figure 2J is a schematic diagram of the time-domain resources of PUSCH repetition type B determined based on method B-1. As shown in Figure 2J, k2 indicates the starting time slot as uplink time slot #3, S indicates the starting symbol as the third symbol, L indicates the number of symbols as 6, and K indicates the number of repetitions as 3. Then, for the first nominal repetition (i.e., nominal repetition #0 in the figure), the terminal starts from the third symbol in uplink time slot #3 and traverses each symbol in turn. Since the third to sixth symbols and the ninth to twelfth symbols in uplink time slot #3 are first-class symbols, these symbols are not determined as PUSCH symbols. Instead, the seventh to eighth symbols, the thirteenth to fourteenth symbols in uplink time slot #3, and the first to second symbols in uplink time slot #4, a total of 6 symbols, are determined as the symbols of the first nominal repetition of PUSCH repetition type B. For the second nominal repetition (i.e., nominal repetition #1 in the diagram), since the first symbol satisfying the first condition after the end symbol of the first nominal repetition is the third symbol in uplink time slot #4, the terminal determines the symbols for the second nominal repetition from the third symbol to the eighth symbol in uplink time slot #4, a total of 6 symbols. For the third nominal repetition (i.e., nominal repetition #2 in the diagram), since the first symbol satisfying the first condition after the end symbol of the second nominal repetition is the ninth symbol in uplink time slot #4, the terminal determines the symbols for the third nominal repetition of PUSCH repetition type B from the ninth symbol to the fourteenth symbol in uplink time slot #4, a total of 6 symbols.
[0262] In one example, taking method B-2 as an example, Figure 2K is a schematic diagram of the time-domain resources of PUSCH repetition type B determined based on method B-2. As shown in Figure 2K, k2 indicates the starting time slot as uplink time slot #3, S indicates the starting symbol as the third symbol, L indicates the number of symbols as 6, and K indicates the number of repetitions as 3. Then, the method for determining the first nominal repetition (i.e., nominal repetition #0 in the figure) to the third nominal repetition (i.e., nominal repetition #2 in the figure) can refer to the embodiments of method B-1 and Figure 2J, which will not be repeated here. For the first nominal repetition, the terminal determines the seventh to eighth symbols in uplink time slot #3 as the first actual repetition (i.e., actual repetition #0 in the figure). Since the first nominal repetition crosses the time slot boundary between uplink time slot #3 and uplink time slot #4, according to method B-2, the thirteenth to fourteenth symbols in uplink time slot #3 are determined as the second actual repetition (i.e., actual repetition #1 in the figure), and the first to second symbols in uplink time slot #4 are determined as the third actual repetition (i.e., actual repetition #2 in the figure). For the second and third nominal repetitions, the symbol of the actual repetition can be determined by referring to the aforementioned embodiments for determining the actual repetition, which will not be repeated here.
[0263] In one example, taking method B-3 as an example, Figure 2L is a schematic diagram of the time-domain resources of PUSCH repetition type B determined based on method B-3. As shown in Figure 2L, k2 indicates the starting time slot as uplink time slot #3, S indicates the starting symbol as the third symbol, L indicates the number of symbols as 6, and K indicates the number of repetitions as 3. Then, the method for determining the first nominal repetition (i.e., nominal repetition #0 in the figure) to the third nominal repetition (i.e., nominal repetition #2 in the figure) can refer to the embodiments of method B-1 and Figure 2J, which will not be repeated here. For the first nominal repetition, the terminal determines the seventh to eighth symbols in uplink time slot #3 as the first actual repetition (i.e., actual repetition #0 in the figure). Since the first nominal repetition crosses the time slot boundary of uplink time slot #3 and uplink time slot #4, according to method B-3, the thirteenth to fourteenth symbols in uplink time slot #3 and the first to second symbols in uplink time slot #4 are determined as the second actual repetition (i.e., actual repetition #1 in the figure). For the second and third nominal repetitions, the symbol of the actual repetition can be determined by referring to the aforementioned embodiments for determining the actual repetition, which will not be repeated here.

[0316] In some embodiments, the first information indicates the time-domain resource configuration of the first data transmission, and the terminal and network device determine the symbol of the first data transmission based on the time-domain resource configuration of the first data transmission. The symbol of the first data transmission satisfies a first condition, which is that it is a symbol not used for the first data transmission.
[0317] In some embodiments, the time-domain resource configuration of the first data transmission includes: a first parameter indicating the starting time slot of the first data transmission; and a second parameter indicating the starting symbol and the number of symbols for the first data transmission.

[0331] In the following, the technical solutions of the embodiments of this disclosure will be described by way of specific implementation.
[0332] In some embodiments, this disclosure provides a PUSCH transmission method, which specifically includes: counting available symbols: starting from the starting symbol, judging each symbol one by one; if the symbol is a first type of symbol, then the symbol is not included in L symbols; otherwise, the symbol is included in L symbols.
[0333] In some embodiments, the first type of symbols is predefined by the protocol and includes at least one of the following: downlink symbols, SSB symbols, sounding reference signal (SRS) symbols, uplink rate matching resource symbols, etc.
[0334] In some embodiments, the first type of symbol is configured by the network device.
[0335] In some embodiments, the available symbol counting termination conditions include: Method 1: End the available symbol counting after finding L symbols. Method 2: Within a time slot, if after traversing the last symbol in the time slot, even if the symbol count is less than L symbols, end the available symbol counting; otherwise, end the available symbol counting after finding L symbols.
[0336] In some embodiments, the method for determining PUSCH repetition based on available symbol counting method 1 is as follows: For PUSCH repetition type A, except for the first repetition, the symbols for each repetition start from the beginning symbol of the reference time slot and are determined according to available symbol counting method 1.
[0337] In some embodiments, method A-1: the reference time slot is the end time slot of the previous repetition. In some embodiments, the first type of symbols also includes symbols that have been assigned to the previous PUSCH repetition; method A-2: the reference time slot is the next time slot after the end time slot of the previous repetition;
[0338] In some embodiments, if the end symbol of the previous repetition precedes the start symbol, then method A-1 is used; otherwise, method A-2 is used.
[0339] In some embodiments, for nominal repetitions of PUSCH repetition type B: except for the first nominal repetition, the start symbol of each nominal repetition is the symbol of the first non-first type symbol after the end symbol of the previous nominal repetition.
[0340] In some embodiments, for actual repetition of PUSCH repetition type B: Method B-1: No actual repetition, send PUSCH directly based on nominal repetition. Method B-2: Reuse existing actual repetition determination methods. Method B-3: Do not segment actual repetition across time slot boundaries.
[0341] In some embodiments, the TBS determination method based on available symbol counting method 2 is as follows: TBS is determined according to the indicated L; TBS is determined according to the number of symbols in the PUSCH of the first time slot; TBS is determined according to the average number of symbols in the PUSCH of all time slots; TBS is determined according to the maximum number of symbols in the PUSCH of all time slots; and TBS is determined according to the minimum number of symbols in the PUSCH of all time slots.
[0342] In some embodiments, terminal capability reporting: the reporting terminal device supports the above-described PUSCH transmission method.
[0343] In some embodiments, the communication method of this disclosure includes: Step 1-1: A network device sends first information to a terminal device, the first information indicating a first time-domain resource, the first time-domain resource being a time-domain resource used to determine when the terminal device sends a first signal. Step 1-2: The terminal device receives the first information sent by the network device and determines the first time-domain resource based on the first information. Step 1-3: The terminal device determines a first TBS based on the first information.
[0344] In some embodiments, the first signal is carried on the PUSCH, and the first time-domain resource is the time-domain resource of the PUSCH.
[0345] In some embodiments, the first information includes a first parameter k2, which is used to determine the starting time slot of the first time domain resource.
[0346] In some embodiments, the first information includes a second parameter S, which is used to determine the start symbol of the first time-domain resource in the start time slot. For example, the second parameter S indicates the index of the start symbol of the first time-domain resource in the start time slot; that is, the index of the start symbol of the first time-domain resource in the start time slot is the second parameter S.
[0347] In some embodiments, the first information includes a third parameter L, which is used to determine the number of symbols in the first time-domain resource. For example, the third parameter L indicates the number of symbols in the first time-domain resource; that is, the number of symbols included in the first time-domain resource is the third parameter L.
[0348] In some embodiments, the symbols of the first time-domain resource are determined according to the first parameter k2, the second parameter S, and the third parameter L, as follows: starting from the symbol indicated by the second parameter S in the time slot indicated by the first parameter k2, each symbol is judged one by one. If the symbol is a first type of symbol, the symbol is not included in the first time-domain resource; otherwise, the symbol is included in the first time-domain resource.
[0349] In some embodiments, the first type of symbols is predefined by the protocol and includes at least one of the following: downlink symbols, SSB symbols, uplink rate matching resources, SRS symbols, etc.
[0350] In some embodiments, the first type of symbol is configured by the network device through higher-layer signaling and / or SIB;
[0351] In some embodiments, the first type of symbols is semi-statically configured.
[0352] In some embodiments, the determination of the symbols of the first time-domain resource is completed according to the following conditions: Method 1: until the first time-domain resource includes L symbols. Method 2: within the time slot indicated by the first parameter k2, if the number of symbols included in the first time-domain resource is less than L symbols after traversing the last symbol in the time slot, then the determination of the symbols of the first time-domain resource is completed; otherwise, the determination of the symbols of the first time-domain resource is completed after the first time-domain resource includes L symbols.
[0353] In some embodiments, Figure 2B shows a schematic diagram of method 1, where k2 indicates time slot #3, S indicates that the starting symbol is the first symbol of the time slot, L = 8, and the first type of symbols are the 3rd to 6th and 9th to 12th symbols in time slot #3. Then the symbols of the first resource are the 8 non-first type symbols starting from the first symbol of time slot #3, which exceeds one time slot. Figure 2C shows a schematic diagram of method 2, where all parameters are the same as in Figure 2(a). However, method 2 restricts the symbols of the first resource from exceeding one time slot, even if the number of symbols of the first resource is less than L symbols. Figure 2D also shows a schematic diagram of method 2, where L = 4, and other parameters are the same as in Figure 2(a). In this case, the first resource will not exceed one time slot, so the number of symbols of the first resource is L symbols.
[0354] In some embodiments, the first information includes a fourth parameter K, which indicates the number of times PUSCH is repeated.
[0355] In some embodiments, for PUSCH repetition type A, if method 1 is used, then: the first time-domain resource corresponding to the first PUSCH repetition is determined according to the first parameter k2, the second parameter S, and the third parameter L; it should be understood that this is the same as described in method 1. Except for the first PUSCH repetition, the first time-domain resource corresponding to each PUSCH repetition starts from the symbol indicated by the second parameter S on the reference time slot and is then determined according to method 1.
[0356] In some embodiments, method A-1: the reference time slot is the end time slot of the previous PUSCH repetition. In some embodiments, the first type of symbols also includes symbols already allocated to the previous PUSCH repetition. It should be understood that this method is to avoid temporal overlap between the first time-domain resources corresponding to the current PUSCH repetition and the first time-domain resources corresponding to the previous PUSCH repetition.
[0357] In some embodiments, method A-2: the reference time slot is the next time slot after the end time slot of the previous PUSCH repetition. In some embodiments, if the end symbol of the first time-domain resource corresponding to the previous PUSCH repetition precedes the symbol indicated by the second parameter S, then method A-1 is used; otherwise, method A-2 is used. It should be understood that this is also to avoid the first time-domain resource corresponding to the current PUSCH repetition overlapping with the first time-domain resource corresponding to the previous PUSCH repetition in the time domain; at the same time, it can also efficiently utilize uplink time-domain resources to improve uplink coverage performance.
[0358] For example, as shown in Figure 2E, method A-1 is used, where k2 indicates time slot #2, S indicates that the starting symbol is the 3rd symbol in the time slot, L = 6, and the first type of symbols are the 3rd to 6th symbols and the 9th to 12th symbols in time slot #2. According to method 1, the first time domain resource corresponding to the first PUSCH repetition spans two time slots, namely time slot #2 and time slot #3. Then, the reference time slot for the second PUSCH repetition is time slot #3. Taking time slot #3 as the starting time slot, according to S and L and method 1, the first time domain resource corresponding to the second PUSCH repetition is determined to be the 3rd to 8th symbols in time slot #3. As shown in Figure 2F, using method A-1, where L = 8 and the remaining parameters are the same as in Figure 2E, in time slot #3, the start symbol (the 3rd symbol) indicated by S precedes the end symbol (the 4th symbol) of the first PUSCH repetition. Therefore, the reference time slot for the second PUSCH repetition is time slot #4. Taking time slot #4 as the starting time slot, according to S and L and method 1, the first time domain resource corresponding to the second PUSCH repetition is determined to be the 3rd to 10th symbols in time slot #4. As shown in Figure 2G, using method A-2, the start symbol (the 3rd symbol) indicated by S overlaps with the end symbol (the 3rd symbol) of the first PUSCH repetition. The reference time slot for the second PUSCH repetition is time slot #4 instead of time slot #3. According to S and L and method 1, the first time domain resource corresponding to the second PUSCH repetition is determined to be the 3rd to 9th symbols in time slot #4.
[0359] In some embodiments, for PUSCH repetition type A, if method 2 is used, each slot of PUSCH repetition type A can be determined using available slot count or physical slot count, wherein the symbols included in the first resource are determined according to method 2 within each slot.
[0360] In some embodiments, for PUSCH repetition type B, if method 1 is used, then: the first time-domain resource corresponding to the first nominal repetition is determined according to the first parameter k2, the second parameter S, and the third parameter L. It should be understood that this is the same as described in method 1. Except for the first nominal repetition, the start symbol of each nominal repetition is the symbol of the first non-first type symbol after the end symbol of the previous nominal repetition.
[0361] In some embodiments, for PUSCH repetition type B actual repetition: Method B-1: No actual repetition, send PUSCH directly based on nominal repetition. Method B-2: Reuse existing actual repetition determination methods. Method B-3: When nominal repetition crosses a slot boundary, it is no longer split into two actual repetitions.
[0362] In some embodiments, the method for determining nominal repetition is shown in Figure 2J, where k2 indicates time slot #3, S indicates the starting symbol is the 3rd symbol of that time slot, L=6, and the first type of symbols are the 3rd to 6th symbols and the 9th to 12th symbols in time slot #3. According to method 1, the first time-domain resource corresponding to the first nominal repetition includes the 7th, 8th, 13th, and 14th symbols in time slot #3 and the 1st and 2nd symbols in time slot #4. Then, the first time-domain resource corresponding to the second nominal repetition starts from the 3rd symbol in time slot #4 and includes a total of 6 consecutive symbols. The first time-domain resource corresponding to the third nominal repetition starts from the 9th symbol in time slot #4 and includes a total of 6 symbols. At the same time, Figure 2J also shows a schematic diagram of method B-1. In this case, it is not necessary to further determine the actual repetition. That is, each nominal repetition is executed once by RM, and each nominal repetition corresponds to an RV. The bit sequence is selected with RV as the starting bit and mapped to the time-frequency resource of each nominal repetition. Figure 2K illustrates method B-2. This scheme requires further determination of the actual repetitions. Each actual repetition is executed once using RM, and each actual repetition corresponds to a RV. A bit sequence is selected starting with the RV and mapped to the time-frequency resources of each actual repetition. The method for determining the actual repetitions is existing technology. Figure 2L illustrates method B-3. The difference from Figure 2K is that when the nominal repetition crosses the time slot boundary, it is no longer divided into two actual repetitions, but rather into one actual repetition.
[0363] In some embodiments, for PUSCH repetition type B, nominal repetition in the prior art can span time slot boundaries, so it is not desirable to use method 2 to determine the first time domain resource for each nominal repetition.
[0364] In some embodiments, for method 2, the method for calculating TBS includes:
[0365] Method a: Determine TBS based on L; in one example, In one example,
[0366] Method b: Determine the TBS based on the symbol count L1′ of the first time-domain resource corresponding to the first PUSCH repetition. In one example, In one example,
[0367] Method c: Calculate the average number of symbols for the first resource corresponding to all PUSCH repetitions. Determine the TBS. In one example, In one example, L′ k This represents the number of symbols corresponding to the k-th PUSCH repetition.
[0368] Method d: The maximum value L′ of the number of symbols corresponding to the first resource for all PUSCH repetitions. max Determine the TBS. In one example, In one example, L′ max =max{L′ k ,k=1,2,...,K},L′ k This represents the number of symbols corresponding to the k-th PUSCH repetition.
[0369] Method e: The minimum value L′ of the number of symbols corresponding to the first resource for all PUSCH repetitions. min Determine the TBS. In one example, In one example, L′ min =min{L′ k ,k=1,2,...,K},L′ k This represents the number of symbols corresponding to the k-th PUSCH repetition.
[0370] In some embodiments, for method 1, the calculation method of TBS can refer to the specific details in "V. TBS Calculation" above, and will not be repeated here.
[0371] In some embodiments, the communication method of this disclosure further includes: Step 2-1: A terminal device sends a first signal, wherein the time domain resources for sending the first signal are determined based on the first time domain resources, the first signal carries a first TB, and the size of the first TB is a first TBS. Step 2-2: A network device receives the first signal sent by the terminal device based on the first time domain resources. Step 2-3: The terminal device determines the first TB based on the first signal and the first TBS.
[0372] In some embodiments, the network device and the terminal device determine the first time domain resource and the first TBS in the same way.
[0373] In some embodiments, the first time-domain resource is used to determine the time-domain resources for transmitting and receiving the first signal. The time-domain resources actually used for transmitting and receiving the first signal may be different from the first time-domain resource. For example, according to some conflict criteria, time-domain resources that are conflicted in the first time-domain resource cannot be used to transmit the first signal.
