[0131] The following is an explanation and interpretation of the terminology used in this disclosure.
[0132] I. Time-domain resources of PUSCH.
[0133] 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.
[0134] 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.
[0135] 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:
[0136] If (L-1)≤7, then SLIV=14×(L-1)+S;
[0137] Otherwise, SLIV = 14 × (14 - L + 1) + (14 - 1 - S), where 0 <L≤14-S。
[0138] 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.
[0139] 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.
[0140] II. PUSCH mapping type
[0141] 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.
[0142] Table 1
[0143] III. PUSCH repetition type
[0144] 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.
[0145] 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 instructs the terminal device on the repetition number of the PUSCH, which is 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).
[0146] In some embodiments, the determination of the K time slots is divided into two methods: physical time slot counting and available time slot counting.
[0147] 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.
[0148] 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 one in which the 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 one in which the symbols indicated by S and L (or SLIV) include downlink symbols, SSB symbols, or SRS symbols.
[0149] 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.
[0150] 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.
[0151] 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.
[0152] 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.
[0153] 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.
[0154] 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.
[0155] 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.
[0156] IV. Transport block processing over multiple slots (TBoMS)
[0157] 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.
[0158] 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.
[0159] 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 on 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.
[0160] 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".
[0161] 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.
[0162] 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.
[0163] 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.
[0164] 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.
[0165] 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.
[0166] 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.
[0167] 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.
[0168] V. TBS Calculation
[0169] The process of TBS calculation is as follows:
[0170] Step 1: Determine the number N of REs used for PUSCH transmission within a time slot. RE .
[0171] 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.
[0172] 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 .
[0173] 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.
[0174] 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 not less than N′. info The minimum value is taken as TBS. Table 2 shows N. info ≤3824 TBS.
[0175] Table 2
[0176] Step 4: If N info >3824, perform the following steps:
[0177] Calculate intermediate variables for quantification in, The round operation represents rounding.
[0178] if in,
[0179] otherwise,
[0180] If N′ info >8424, in,
[0181] otherwise,
[0182] VI. Transmission Occasion (TO)
[0183] The transmission timing of PUSCH is defined as a time 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.
[0184] In some embodiments, for PUSCHs that support cross-slot transport block processing, the symbol allocation for each slot is the same, which reduces the flexibility of time-domain resource allocation, wastes some uplink resources, and thus affects uplink coverage performance.
[0185] This disclosure provides a communication method, communication device, communication system, storage medium, and program product. The communication device acquires first information, which includes at least a first parameter. The first parameter is used to determine the number of symbols in the first data transmission. The value of the first parameter is greater than the number of symbols in a time slot. Thus, by expanding the value range of the first parameter, this disclosure enables the time domain resources of the first data transmission to span multiple time slots, improving the flexibility of time domain resource allocation and enhancing the utilization and coverage performance of time domain resources.
[0186] In some embodiments, the first data transmission can be either an uplink transmission or a downlink transmission.
[0187] In some embodiments, the first data transmission may be PUSCH or physical downlink shared channel (PDSCH).
[0188] In some embodiments, the first data transmission may be a PUSCH of repeating type A, a PUSCH of repeating type B, or a PUSCH of TBoMS.
[0189] The communication method of this disclosure embodiment is described below using PUSCH as an example of the first data transmission.
[0190] 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.
[0191] In step S2101, the network device sends the first information.
[0192] In some embodiments, the terminal receives first information.

[0197] In some embodiments, the first information indicates at least one symbol of PUSCH.
[0198] In some embodiments, the first information indicates at least the number of symbols in the PUSCH.
[0199] In some embodiments, the first information also indicates at least one of the following: the start symbol of the PUSCH, the number of repetitions of the PUSCH, and the start time slot of the PUSCH.
[0200] In some embodiments, the first information includes at least a first parameter, which is used to determine the number of symbols in the PUSCH, and the value of the first parameter is greater than the number of symbols in a time slot.
[0201] In one example, the first parameter is represented by L, then in, The number of symbols in a time slot.
[0202] In some embodiments, the number of symbols in PUSCH is equal to the value of L, that is, PUSCH consists of L symbols.
[0203] In some embodiments, the value of L provided by the legacy protocol, as shown in Table 1, is less than or equal to 14, meaning the value of L is less than or equal to the number of symbols in a time slot. In other words, the L provided in this embodiment of the present disclosure, compared to L in the legacy protocol, raises the lower limit of L, allowing PUSCH time-domain resources to span multiple time slots and improving the flexibility of PUSCH time-domain resource allocation.
[0204] In some embodiments, the number of symbols in a PUSCH is less than or equal to the product of a first value and a second value, i.e., the value of L is less than or equal to the product of the first value and the second value. The first value indicates the maximum number of time slots a PUSCH can occupy, and the second value indicates the number of symbols within a single time slot. In other words, the first value indicates the maximum number of time slots a PUSCH can occupy, and the product of the first and second values can be understood as the maximum number of symbols a PUSCH can occupy.
[0205] In one example, the first value is N′ max Indicates that the second value is... Indicate, then
[0206] In one example, the range of values for L is:

In one example, N′ max It can be equal to 16, 32, 64, 128, or 256.
[0208] In one example, the maximum number of symbols L occupied by PUSCH is no more than or Expressed as a formula or
[0209] In one example, the maximum number of time slots occupied by PUSCH is 16, 32, 64, 128, or 256, expressed by the formula: or

The third parameter is used to determine the start symbol of the PUSCH, the fourth parameter indicates the number of repetitions of the PUSCH, and the fifth parameter is used to determine the start time slot of the PUSCH. In one example, the third parameter is represented by S, the fourth parameter by K, and the fifth parameter by k2.

[0220] In one example, the maximum number of time slots occupied by PUSCH is 16, 32, 64, 128, or 256, expressed by the formula: or
[0221] In step S2102, the terminal determines the symbol of PUSCH based on the first information.
[0222] In some embodiments, when the first information includes k2, S, and L, the terminal determines the symbol of PUSCH based on k2, S, and L.
[0223] In some embodiments, the terminal determines L consecutive symbols as symbols for PUSCH, starting from the start position indicated by S in the time slot indicated by k2 (denoted as the physical symbol count).
[0224] In one example, Figure 3A is a schematic diagram of the time-domain resources of PUSCH determined based on the physical symbol count. As shown in Figure 3A, k2 indicates special time slot #2, S=2, that is, S indicates the third symbol, and L=30, that is, L indicates that the number of symbols in PUSCH is 30. Then, starting from the third symbol in special time slot #2, the terminal determines 30 consecutive symbols as PUSCH symbols, that is, the symbols of PUSCH include the third symbol in special time slot #2 to the fourth symbol in uplink time slot #4.
[0225] In some embodiments, the terminal, starting from the beginning position indicated by S in the time slot indicated by k2, determines L consecutive symbols that satisfy a first condition as PUSCH symbols, wherein the first condition is that the PUSCH symbols do not overlap with a first type of symbols. The first type of symbols are symbols not used for PUSCH (denoted as the available symbol count).
[0226] In some embodiments, the available symbol count can also be understood as starting from the starting position indicated by S in the time slot indicated by k2, traversing each symbol sequentially, and not determining the symbols that do not meet the first condition as PUSCH symbols.
[0227] In some embodiments, the first type of symbol may be a predefined symbol or a symbol configured by the network device.
[0228] In some embodiments, the first type of symbol may be a semi-statically configured symbol, a symbol configured by the network device through higher-layer signaling, or a symbol configured by the network device through a system information block (SIB).
[0229] In some embodiments, the first type of symbols includes at least one of the following: synchronization signal block symbols, uplink symbols, downlink symbols, probe reference signal symbols, and symbols indicating higher-layer signaling.
[0230] In some embodiments, when the first data transmission is PUSCH, the first type of symbol includes at least one of the following: downlink symbol, SSB symbol, SRS symbol, symbol indicated by higher-layer signaling, etc.
[0231] In some embodiments, when the first data transmission is PDSCH, the first type of symbols includes at least one of the following: uplink symbols, symbols indicated by higher-layer signaling, etc.
[0232] In one example, Figure 3B is a schematic diagram of the time-domain resources of PUSCH determined based on the available symbol count. As shown in Figure 3B, k2 indicates special time slot #2, S=2, that is, S indicates the third symbol, and L=30, that is, L indicates that the number of PUSCH symbols is 30. Then, starting from the third symbol in special time slot #2, the terminal judges each symbol one by one. Since the third to eighth symbols and the eleventh symbol in special time slot #2 are first-class symbols, these symbols are not determined as PUSCH symbols. Instead, the ninth to tenth symbols, the twelfth to fourteenth symbols in special time slot #2, all symbols in uplink time slot #3, and the first to eleventh symbols in uplink time slot #4, a total of 30 symbols, are determined as PUSCH symbols.
[0233] In some embodiments, when the first information includes k2, S, L, and K, the terminal determines the symbol of PUSCH based on k2, S, L, and K.
[0234] In some embodiments, the method for determining the symbols of PUSCH based on k2, S, L, and K is similar to the physical symbol counting method described above, that is: the terminal determines L×K consecutive symbols as the symbols of PUSCH starting from the starting position indicated by S in the time slot indicated by k2.
[0235] In some embodiments, the method for determining the symbols of PUSCH based on k2, S, L, and K is similar to the available symbol counting method described above, that is: starting from the starting position indicated by S in the time slot indicated by k2, the terminal determines L×K consecutive symbols that satisfy the first condition as the symbols of PUSCH.
[0236] In some embodiments, when K>1, the PUSCH is transmitted K times in the time domain, with each repetition including the same number of symbols, i.e., each repetition includes L symbols, and all repetitions of the PUSCH include a total of L×K symbols. In other words, starting from the first symbol of the PUSCH, every L consecutive PUSCH symbols form a group, which can be divided into K groups in total. The symbols of each group of L PUSCH symbols are sequentially assigned to one PUSCH repetition.
[0237] In one example, Figure 3C is a schematic diagram of the time-domain resources for PUSCH repetition determined based on physical time slot counts. As shown in Figure 3C, k2 indicates special time slot #2, S=12, meaning S indicates the thirteenth symbol, L=30, meaning L indicates the number of symbols in one PUSCH repetition is 30, K=2, meaning PUSCH is repeated twice, and the total number of PUSCH symbols is 30×2=60. Therefore, starting from the thirteenth symbol in special time slot #2, the terminal identifies 60 consecutive symbols as PUSCH symbols, meaning the PUSCH symbols include the thirteenth symbol in special time slot #2 to the second symbol in special time slot #7. Specifically, the terminal identifies the thirteenth symbol in special time slot #2 to the fourteenth symbol in uplink time slot #4 as the first PUSCH repetition (i.e., PUSCH repetition #0 in the figure), and the terminal identifies the first symbol in downlink time slot #5 to the second symbol in special time slot #7 as the second PUSCH repetition (i.e., PUSCH repetition #1 in the figure).
[0238] In one example, Figure 3D is a schematic diagram of the time-domain resources for PUSCH repetition determined based on the available symbol count. As shown in Figure 3D, k2 indicates special time slot #2, S=12, meaning S indicates the thirteenth symbol, L=30, meaning L indicates the number of symbols in one PUSCH is 30, K=2, meaning PUSCH is repeated twice, and the total number of PUSCH symbols is 30×2=60. The terminal then starts judging each symbol from the thirteenth symbol in special time slot #2. Since all symbols in downlink time slot #5, all symbols in downlink time slot #6, and the first to twelfth symbols in special time slot #7 are Class I symbols, these symbols are not considered PUSCH symbols. Instead, the thirteenth symbol in special time slot #2 to the fourteenth symbol in uplink time slot #4, and the thirteenth symbol in special time slot #7 to the fourteenth symbol in uplink time slot #9, a total of 60 symbols, are determined as PUSCH symbols. Specifically, the terminal determines the thirteenth symbol in special time slot #2 to the fourteenth symbol in uplink time slot #4 as the first repetition of PUSCH (i.e., PUSCH repetition #0 in the figure), and the terminal determines the thirteenth symbol in special time slot #7 to the fourteenth symbol in uplink time slot #9 as the second repetition of PUSCH (i.e., PUSCH repetition #1 in the figure).
[0239] In step S2103, the network device determines the symbol of PUSCH based on the first information.
[0240] In some embodiments, the network device and the terminal determine the symbol of the PUSCH in the same way, so that the network device and the terminal can reach a consensus on the time domain resources of the PUSCH, and thus determine on which time domain resources the TB carried by the PUSCH is received.
[0241] In some embodiments, step S2103 may be performed before step S2102 or simultaneously with step S2102.
[0242] In step S2104, the terminal determines the TBS of the TB carried by the PUSCH based on the first information.
[0243] In some embodiments, the terminal determines second information based on first information, the second information indicating the number of REs used for PUSCH in a PRB. Based on the second information, it determines third information, the third information indicating the number of REs used for PUSCH. Based on the third information, it determines the TBS.

[0246] In some embodiments, the number of symbols in PUSCH is L, the number of first-class symbols overlapping with the symbols in PUSCH is L′, and L′ is the number of first-class symbols among the L symbols. The second information is represented by N′. RE This indicates that the third information is used for N. RE This indicates that the methods used by the terminal to determine the TBS include:

[0255] In step S2105, the network device determines the TBS of the TB carried by the PUSCH based on the first information.
[0256] In some embodiments, the network device and the terminal determine the TBS using the same method based on the first information, so that the network device and the terminal can reach a consensus on the TBS carried by the PUSCH, and thus can accurately receive the TBS carried by the PUSCH.
[0257] In some embodiments, step S2105 may be executed before step S2104, simultaneously with step S2103, or simultaneously with step S2104.
[0258] In step S2106, the terminal sends TB on PUSCH based on TBS.
[0259] In some embodiments, the terminal transmits a TB on a defined symbol of a PUSCH, and the size of the transmitted TB is TBS.
[0260] In some embodiments, when the symbols of PUSCH are determined based on the physical symbol count, if the symbols of PUSCH include first-class symbols, i.e. symbols not used for PUSCH, then the terminal does not transmit the TB carried by PUSCH on the first-class symbols.

[0295] In step S2202, the terminal determines the symbol of PUSCH based on the fourth information.
[0296] In some embodiments, when the fourth information includes k2, S, N, and L, the terminal determines the symbol of PUSCH based on k2, S, N, and L.
[0297] In some embodiments, the terminal determines L×N consecutive symbols as symbols for PUSCH, starting from the start position indicated by S in the time slot indicated by k2 (denoted as physical symbol count).
[0298] In one example, Figure 3E is a schematic diagram of the time-domain resources of PUSCH determined based on physical symbol count. As shown in Figure 3E, k2 indicates special time slot #2, S=2, that is, S indicates the third symbol, N=6, that is, the number of first time-domain resources included in PUSCH is 6, L=5, that is, L indicates the number of symbols in the first time-domain resources is 5. Therefore, the number of symbols in PUSCH is 5×6=30. Then, starting from the third symbol in special time slot #2, the terminal determines 30 consecutive symbols as symbols for PUSCH, that is, the symbols of PUSCH include the third symbol in special time slot #2 to the fourth symbol in uplink time slot #4.
[0299] In some embodiments, the terminal, starting from the beginning position indicated by S in the time slot indicated by k2, determines L×N consecutive symbols that satisfy a first condition as PUSCH symbols, wherein the first condition is that the PUSCH symbols do not overlap with a first type of symbols. The first type of symbols are symbols not used for PUSCH (denoted as the available symbol count).
[0300] In some embodiments, the available symbol count can also be understood as starting from the starting position indicated by S in the time slot indicated by k2, traversing each symbol sequentially, and not determining the symbols that do not meet the first condition as PUSCH symbols.
[0301] In some embodiments, the first type of symbol may be a predefined symbol or a symbol configured by the network device.
[0302] In some embodiments, the first type of symbol may be a semi-statically configured symbol, a symbol configured by the network device through higher-layer signaling, or a symbol configured by the network device through a system information block (SIB).
[0303] In some embodiments, the first type of symbols includes at least one of the following: synchronization signal block symbols, uplink symbols, downlink symbols, probe reference signal symbols, and symbols indicating higher-layer signaling.
[0304] In some embodiments, when the first data transmission is PUSCH, the first type of symbol includes at least one of the following: downlink symbol, SSB symbol, SRS symbol, symbol indicated by higher-layer signaling, etc.
[0305] In some embodiments, when the first data transmission is PDSCH, the first type of symbols includes at least one of the following: uplink symbols, symbols indicated by higher-layer signaling, etc.
[0306] In one example, Figure 3F is a schematic diagram of the time-domain resources of PUSCH determined based on the available symbol count. As shown in Figure 3F, k2 indicates special time slot #2, S=2, that is, S indicates the third symbol, N=6, that is, the number of first time-domain resources included in PUSCH is 6, L=5, that is, L indicates the number of symbols of the first time-domain resources is 5. Therefore, the number of symbols in PUSCH is 5×6=30. Then, starting from the third symbol in special time slot #2, the terminal judges each symbol one by one. Since the third to eighth symbols and the eleventh symbol in special time slot #2 are first-class symbols, these symbols are not determined as PUSCH symbols. Instead, the ninth to tenth symbols, the twelfth to fourteenth symbols in special time slot #2, all symbols in uplink time slot #3, and the first to eleventh symbols in uplink time slot #4, a total of 30 symbols, are determined as PUSCH symbols.
[0307] In some embodiments, when the first information includes k2, S, L, N, and K, the terminal determines the symbol of PUSCH based on k2, S, L, N, and K.
[0308] In some embodiments, the method for determining the symbols of PUSCH based on k2, S, L, N, and K is similar to the physical symbol counting method described above, that is: the terminal determines L×N×K consecutive symbols as the symbols of PUSCH, starting from the starting position indicated by S in the time slot indicated by k2.
[0309] In some embodiments, the method for determining the symbols of PUSCH based on k2, S, L, and K is similar to the available symbol counting method described above, that is: starting from the starting position indicated by S in the time slot indicated by k2, the terminal determines the symbols of PUSCH as L×N×K consecutive symbols that satisfy the first condition.
[0310] In some embodiments, when K>1, the PUSCH is transmitted K times in the time domain, with each repetition including the same number of symbols, i.e., each repetition includes L×N symbols, and all repetitions of the PUSCH include a total of L×N×K symbols. In other words, starting from the first symbol of the PUSCH, every L×N consecutive PUSCH symbols form a group, which can be divided into K groups in total. The symbols of each group of L×N PUSCHs are sequentially allocated to one PUSCH repetition.
[0311] In one example, Figure 3G is a schematic diagram of the time-domain resources for PUSCH repetition determined based on physical time slot counts. As shown in Figure 3G, k2 indicates special time slot #2, S=12, meaning S indicates the thirteenth symbol, N=6, meaning the number of first time-domain resources included in PUSCH is 6, L=5, meaning L indicates the number of symbols in the first time-domain resources is 5, and K=2, meaning PUSCH is repeated twice. Therefore, the total number of symbols in PUSCH is 5×6×2=60. The terminal then determines 60 consecutive symbols as PUSCH symbols, starting from the thirteenth symbol in special time slot #2. That is, the symbols in PUSCH include the thirteenth symbol in special time slot #2 to the second symbol in special time slot #7. Specifically, the terminal determines the thirteenth symbol in special time slot #2 to the fourteenth symbol in uplink time slot #4 as the first repetition of PUSCH (i.e., PUSCH repetition #0 in the figure), and the terminal determines the first symbol in downlink time slot #5 to the second symbol in special time slot #7 as the second repetition of PUSCH (i.e., PUSCH repetition #1 in the figure).
[0312] In one example, Figure 3H is a schematic diagram of the time-domain resources for PUSCH repetition determined based on the available symbol count. As shown in Figure 3H, k2 indicates special time slot #2, S=12, that is, S indicates the thirteenth symbol, N=6, that is, the number of first time-domain resources included in PUSCH is 6, L=5, that is, L indicates the number of symbols of the first time-domain resources is 5, K=2, that is, PUSCH is repeated 2 times, so the total number of PUSCH symbols is 5×6×2=60. Then the terminal starts from the thirteenth symbol in special time slot #2 and judges each symbol one by one. Since all symbols in downlink time slot #5, all symbols in downlink time slot #6, and the first to twelfth symbols in special time slot #7 are first-class symbols, these symbols are not determined as PUSCH symbols. Instead, the thirteenth symbol in special time slot #2 to the fourteenth symbol in uplink time slot #4, and the thirteenth symbol in special time slot #7 to the fourteenth symbol in uplink time slot #9, a total of 60 symbols, are determined as PUSCH symbols. Specifically, the terminal determines the thirteenth symbol in special time slot #2 to the fourteenth symbol in uplink time slot #4 as the first repetition of PUSCH (i.e., PUSCH repetition #0 in the figure), and the terminal determines the thirteenth symbol in special time slot #7 to the fourteenth symbol in uplink time slot #9 as the second repetition of PUSCH (i.e., PUSCH repetition #1 in the figure).
[0313] In step S2203, the network device determines the symbol of PUSCH based on the fourth information.
[0314] In some embodiments, the network device and the terminal determine the symbol of the PUSCH in the same way, so that the network device and the terminal can reach a consensus on the time domain resources of the PUSCH, and thus determine on which time domain resources the TB carried by the PUSCH is received.
[0315] In some embodiments, step S2203 may be performed before step S2202 or simultaneously with step S2202.
[0316] In step S2204, the terminal determines the TBS of the TB carried by the PUSCH based on the fourth information.

Step 1-2: The terminal device receives the first information sent by the network device and determines the time-domain resources of the PUSCH based on the first information. Step 1-3: The terminal device determines a first TBS based on the first information.
[0377] In some embodiments, the first information is carried on the PUSCH, and the time domain resources of the PUSCH are the time domain resources of the PUSCH.
[0378] In some embodiments, the first information includes k2, which is used to determine the starting time slot of the time domain resources of PUSCH.
[0379] In some embodiments, the first information includes S, which is used to determine the start symbol of the PUSCH's time-domain resources in the start time slot. For example, S indicates the index of the start symbol of the PUSCH's time-domain resources in the start time slot; that is, the index of the start symbol of the PUSCH's time-domain resources in the start time slot is S.
[0380] In some embodiments, the first information includes L, which is used to determine the number of symbols in the time-domain resources of the PUSCH. For example, the time-domain resources of the PUSCH include L symbols. It should be understood that, for ease of description, this method is referred to as Method 1. Further optionally, S and L satisfy the following condition:

[0384] In some embodiments, the first information includes N, which is used to determine the number of symbols in the time-domain resources of the PUSCH. N is an integer, N>1, or N≥1. For example, the time-domain resources of the PUSCH include L×N symbols. It should be understood that, for ease of description, this method is referred to as Method 2. Further optionally, S, L, and N satisfy the following conditions:
[0385] or Where, N max This represents the maximum value of N, for example, N max =16, 32, 64, 128, 256, etc.

[0387] In some embodiments, determining the symbols of the PUSCH time-domain resources based on k2, S, and L includes two possible methods: physical symbol counting, where the PUSCH time-domain resources consist of L consecutive symbols starting from the symbol indicated by S in the time slot indicated by k2; and symbol counting, where each symbol is evaluated sequentially starting from the symbol indicated by S in the time slot indicated by k2. If the symbol is a first-class symbol, it is not included in the PUSCH time-domain resources; otherwise, it is included until the PUSCH time-domain resources include L symbols.

It should be understood that the above method applies to method 2.
[0389] Optionally, the first information includes K, which indicates the number of times the PUSCH is repeated, where K>1 or K≥1. It should be understood that if the first information includes K and K>1, then the PUSCH is transmitted repeatedly in the time domain, and the time domain resources of the PUSCH are also repeated in the time domain, repeated K times, each time including the same number of symbols, i.e., L symbols (corresponding to method 1), or L×N symbols (corresponding to method 2).
[0390] In some embodiments, if the first information includes K, the symbols of the PUSCH time-domain resources are determined based on k2, S, L, and K, including the following two possible methods: Physical symbol counting, where the PUSCH time-domain resources include L×K consecutive symbols starting from the symbol indicated by S in the time slot indicated by k2. Available symbol counting: Starting from the symbol indicated by S in the time slot indicated by k2, each symbol is evaluated one by one. If the symbol is a first-class symbol, it is not included in the PUSCH time-domain resources; otherwise, it is included in the PUSCH time-domain resources, until the PUSCH time-domain resources include L×K symbols. It should be understood that the above methods apply to method 1.

For example, in the time-domain resources of a PUSCH, the L consecutive symbols starting from the (k-1)×L+1th symbol (or, the symbol with index (k-1)×L) are assigned to the kth PUSCH repetition, where k = 1, 2, ..., K.
[0392] In some embodiments, if the first information includes K, the symbols of the PUSCH time-domain resources are determined based on k2, S, L, N, and K, including the following two possible methods: Physical symbol counting, where the PUSCH time-domain resources include a continuous L×N×K symbols starting from the symbol indicated by S in the time slot indicated by k2; or Symbol counting, where each symbol is evaluated sequentially starting from the symbol indicated by S in the time slot indicated by k2. If the symbol is a first-class symbol, it is not included in the PUSCH time-domain resources; otherwise, it is included until the PUSCH time-domain resources include L×N×K symbols. It should be understood that the above method applies to method 2.
[0393] In some embodiments, within the time-domain resources of a PUSCH, starting from the first symbol of the time-domain resources of a PUSCH, every consecutive L×N symbols are grouped together, for a total of K groups. Each group of L×N symbols is sequentially assigned to one PUSCH repetition. For example, in the time-domain resources of a PUSCH, the consecutive L×N symbols starting from the (k-1)×L×N+1th symbol (or, the symbol with index (k-1)×L×N) are assigned to the kth PUSCH repetition, where k = 1, 2, ..., K.
[0394] In some embodiments, the time-domain resources of the PUSCH include a maximum of 32, 64, 128, or 256 time slots. For example, in method 1, 64, 128, or 256; for method 2, 64, 128, or 256.

[0397] Method a:
[0398] Method b: L′ represents the number of first-class symbols among the L symbols. It should be understood that subtracting the number of first-class symbols in method b makes the TBS calculation more accurate.
[0399] In some embodiments, M represents the maximum number of REs that an RB can include for transmitting data, M = 156, 168, or can be configured via higher-layer signaling.
[0400] Optionally, for method 2, the calculation method for TBS includes: based on N RE =N·min(M,N′) RE )·n PRB or N RE =N·N′ RE ·n PRB Determine TBS, It should be understood that the definition of M is the same as above.

Step 2-2: A network device receives the first signal sent by the terminal device according to the time-domain resources of the PUSCH. Step 2-3: The network device determines the first TB according to the first signal and the first TBS.
[0402] In some embodiments, the network device and the terminal device determine the time-domain resources of the PUSCH and the first TBS in the same way.
[0403] In some embodiments, the time-domain resources of the PUSCH are 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 time-domain resources of the PUSCH. For example, according to some collision criteria, the time-domain resources of the PUSCH that are in conflict cannot be used to transmit the first signal.
