Considering that, due to LBT, the terminal does not necessarily have to use any time slot or mini-time slot. It is not always the case that the channel is idle in a lot, e.g. If you listen to the channel only before the time slot and find it idle, PUSCH transmission is required only in the later time slot, and the base station By receiving the contents of the mail slot, the data information can be correctly decoded. Before the mini-timeslot and four time slots, the channel is idle. If it detects this, it transmits PUSCH in the last mini-timeslot and the four time slots.

[0126] All the above-mentioned optional technical solutions can be combined in any combination to form optional embodiments of the present disclosure. can be formed, so the description will be omitted here.

[0127] FIG. 4 illustrates a method for allocating time domain resources and a method for transmitting data according to an exemplary embodiment. As shown in FIG. 4, the method for allocating time domain resources and data The data transmission method is applied to a terminal and includes the following steps S401 to S403.

[0128] In step S401, the base station transmits DCI signaling.

[0129] Here, the DCI signaling is used to indicate the time domain resources for the terminal's PUSCH transmission. The time domain resource may include at least one time slot. may include at least one mini-timeslot and may include at least one time slot. Each time slot may include a main time slot and at least one mini time slot. Each tag contains 14 symbols, which can be represented by numbers 0 to 13. A mini-time slot may include at least two mini-time slots, and each mini-time slot The time slots may be of the same or different lengths. It contains mini-timeslots, each of which is 7 symbols long, The first mini-time slot contains symbols #0 through #6, and the second mini-time slot contains symbols #1 through #6. The time slot includes symbols #7 to #13. Referring to FIG. 6, the time slot is divided into four parts. The first mini-timeslot has a length of two symbols; Contains symbol #0 through symbol #1, and the second mini-timeslot is four symbols long. The third mini-timeslot is 4 in length, containing symbols #2 through #5. Four symbols, including symbols #6 through #9, and the fourth mini-time slot The length of the data is four symbols, including symbols #10 to #13. In this case, the PUSCH of NR-U is used for data transmission based on time slots and mini-time slots. A time domain resource scheduling method is implemented to support simultaneous lot-based transmission. The formula is to schedule based on each time slot, and to schedule based on each mini time slot. or for each time slot and each mini-time slot The idea is to schedule based on the above.

[0130] In another possible implementation, the DCI signaling further includes the opening of time domain resources. Indicates the start symbol, the end symbol, or the start symbol and the end symbol. The symbol indicates the start symbol of the terminal PUSCH transmission, and the start symbol is 14 The end symbol is the end symbol of the terminal PUSCH transmission. show.

[0131] The DCI signal is sent according to the time domain resource and the time domain resource scheduling method. Start symbol, end symbol, or start symbol and end symbol indicated by nulling has different definitions. Specifically, it includes the following cases:

[0132] In the first case, the time domain resource is at least one time slot, The scheduling method for the inter-area resources is based on each time slot. The key is to

[0133] For the first case, the start symbol of the time domain resource is at least one time stamp. The first time slot in a time slot or at least one time slot in each time slot The end symbol of a time domain resource is at least one The last time slot or at least one of the time slots in the time slot For each time slot, the starting symbol of the time domain resource is At least one time slot is for the first time slot, and the end The end symbol is for the last time slot in at least one time slot. and the start symbol of the time domain resource is at least one time slot. The first time slot in the For each time slot of the time slots, The start symbol of at least one time slot is for each time slot. The end symbol is for each time slot of at least one time slot. The start symbol of the time domain resource may be at least one of the time slots. for each time slot, and the end symbol is It may be for the last time slot in.

[0134] In one possible implementation, there may be only one starting symbol of the time domain resource. stomach.

[0135] For example, a time domain resource contains four time slots and the start symbol is symbol # 7, for the first time slot only, with the end symbol being symbol #8 , if it is for the 4th time slot only, the first time slot's synchronisation All time domain resources between symbol #7 and symbol #8 of the 4th time slot are , is a time domain resource allocated to a terminal for PUSCH transmission, and specifically, Symbol #7 to #13 in the first time slot, and #1 in the second time slot. Symbol #0 to Symbol #13, 3rd time slot Symbol #0 to Symbol #13 , and includes symbols #0 to #8 of the fourth time slot.

[0136] For example, the time domain resource includes four time slots and the start symbol is a single The first symbol is symbol 0 for each time slot, the second symbol is symbol 6 for each time slot, and the third symbol is symbol 7 for each time slot. For a time slot, symbols #0 to #6 of each time slot are , is a time domain resource allocated to a terminal for PUSCH transmission, and specifically, Symbol #0 to #6 in the first time slot, Symbol #1 in the second time slot Symbol #0 to Symbol #6 of the third time slot, and Includes symbols #0 to #6 of the 4th time slot.

[0137] For example, the time domain resource includes four time slots and the start symbol is a single Boolean #7 is for the first time slot only and the end symbol is symbol #12, for each time slot, the symbol for the first time slot time slot #7 to symbol #12, the second time slot #0 to symbol #12, Symbol #0 to #12 of the 1st time slot and Symbol #12 of the 4th time slot Symbols #0 to #12 are the time domains assigned to the terminal for PUSCH transmission. It is a regional resource.

[0138] For example, the time domain resource includes four time slots and the start symbol is a single for each time slot with the end symbol being symbol #12, If it is for the last timeslot only, the symbol in the first timeslot #7~symbol #13, the second time slot's symbol #7~symbol #13, the third time slot's symbol #7~symbol #13 Symbols #7 to #13 in the first time slot and #14 in the fourth time slot Symbols #7 to #12 are the time domains assigned to the terminal for PUSCH transmission. It is a resource.

[0139] In another possible implementation, the start symbol of the time domain resource may be multiple. The start symbols are the start symbols for the first time slot. There may be one or multiple start symbols for each time slot. For example, A time slot has 14 symbols, with the two starting symbols being symbol #0 and If specified as symbol #7, multiple start symbols are available in the first timeslot only. For example, the first time slot has two symbols, symbol #0 and #7. The start symbols of all other time slots are symbol #0. If multiple start symbols are for each time slot, then each time slot has two starting symbols, symbol #0 and symbol #7. For example, for a timeslot having symbols #0 and #7, the terminal If the terminal detects that the channel is idle before Transmit data information and the terminal detects that the channel is idle before symbol #0. If no detection occurs and the channel is detected as idle before symbol #7 , the terminal is mapped from symbol #7 to the end symbol, for example symbol #13. Only data mapped to symbols #0 to #6 can be transmitted. In this case, D The CI signaling further includes N RVs and the time domain resource for each time the terminal is to use. This indicates that PUSCH transmission is performed using the corresponding RV in each slot. where N is the number of time slots in the time domain resource indicated by the DCI signaling. That is, when PUSCH is transmitted in multiple time slots, the number of PUSCHs is and the number of time slots are the same, and the terminal uses N time slots in the time domain resource. PUSCH transmission is performed using the corresponding RV in each slot.

[0140] Consider that the transmission of each timeslot contains the complete PUSCH data information. Considering this, the redundancy version (RV) adopted in the data information corresponding to each time slot is Because of LBT, the terminal does not necessarily know in which time slot the channel is idle. It does not necessarily detect that the channel is in the last time slot, for example, only before If idle is detected, PUSCH transmission is performed only in the last timeslot The base station receives the contents of that one time slot to correctly transmit the data information. Before the last three time slots, the channel is If it detects that the PUSCH is in the 100mW, it will transmit PUSCH in the last three time slots. The base station combines the PUSCH data information of the three received time slots. This allows the signal to be decoded and reception accuracy improved.

[0141] In the second case, the time domain resource is at least one mini-timeslot. The time domain resource scheduling scheme is based on each mini-time slot. The key is to Juul it.

[0142] In this case, the start symbol of the time domain resource is the first mini-timeslot or for each mini-timeslot, and the DCI signaling may further indicates the number of symbols contained in each mini-timeslot and is indicated by the DCI signaling. The number of symbols contained in each mini-timeslot may be the same or different.

[0143] For example, the start symbol of the time domain resource is for the first mini-timeslot. where DCI indicates the number of symbols and is for each mini-timeslot. In this case, the time domain resource is N consecutive mini-timers with the same number of symbols. For example, the start symbol of the first mini-timeslot is The data bit is symbol 0 and is included in each mini-timeslot indicated by DCI signaling. If the number of symbols included in each mini-timeslot is three, the first mini-timeslot will The first mini-timeslot contains symbols #0 to #2, the second mini-timeslot contains symbols #3 to #5, and the third mini-timeslot contains symbols #4 to #6. The second mini-timeslot contains symbols #6 through #8, and the fourth mini-timeslot contains symbols Indicates that #9~#11 are included.

[0144] For example, the start symbol of the time domain resource is the first mini-timeslot. The DCI indicates the number of symbols and In this case, the time domain resource is a set of N consecutive milliseconds with different numbers of symbols. For example, the first mini-timeslot is The starting symbol is symbol 0 and each mini-time slot indicated by DCI signaling If the number of symbols in the first mini-time slot is 2, 4, 4, and 4, respectively, The lot contains symbols #0 to #1, and the second mini-time slot contains symbols #2 to #5 The third mini-time slot contains symbols #6-#9, and the fourth mini-time slot contains symbols #7-#9. Indicates that the slot contains symbols #10 to #13.

[0145] Also, for example, the start symbol of the time domain resource is for each mini-timeslot. where DCI indicates the number of symbols and is for each mini-timeslot. In this case, the time domain resource is divided into N mini-tasks with the same number of symbols but not consecutive. For example, the start symbol of each mini-time slot may be included. The bolts are symbol #0, symbol #3, symbol #7, and symbol #10, respectively. The number of symbols contained in each mini-timeslot indicated by the DCI signaling will eventually If the number is also 3, the first mini-timeslot contains symbols #0 to #2, and the second mini-timeslot contains symbols #1 to #2. The second mini-timeslot contains symbols #3 to #5, and the third mini-timeslot contains symbols #7~#9, and the fourth mini-timeslot contains symbols #10~#12. In this case, the second and third mini-time slots are consecutive. not separated by symbol #6.

[0146] Also, for example, the start symbol of the time domain resource is for each mini-timeslot. where DCI indicates the number of symbols and is for each mini-timeslot. In this case, the time domain resource is divided into N mini- tasks with different numbers of symbols and not consecutive. For example, the start symbol of each mini-time slot may be included. The symbols are symbol #0, symbol #3, symbol #7, and symbol #10, respectively, and The number of symbols contained in each mini-timeslot indicated by DCI signaling is If it is 2, 3, 3, 4, the first mini-timeslot contains symbols #0 to #1, The second mini-time slot contains symbols #3 through #5, and the third mini-time slot The fourth mini-timeslot contains symbols #7 to #9, and the fourth mini-timeslot contains symbols #10 to #13. It means to include.

[0147] The start symbol of the time domain resource may be for each mini-timeslot. In this case, the adjacent symbols before the start symbol of the Sth mini-time slot are , the end symbol of the S-1th mini-timeslot, where S is a value from 1 to M. where M is the number of mini-timeslots in the time domain resource. For example, A time domain resource includes one time slot, and the time slot is divided into four mini-time slots. In this case, you just need to give the start symbols of the four mini-time slots. Often, the adjacent symbol before the start symbol of the second mini-timeslot is the first It is the end symbol of the first mini-timeslot and the start symbol of the third mini-timeslot. The adjacent symbol before the 4th is the end symbol of the second mini-timeslot. The adjacent symbol before the start symbol of the 3rd mini-timeslot is the 4th mini-timeslot. It is the ending symbol of the im slot.

[0148] For example, the time domain resource may only provide a number of starting symbols, e.g., symbol #0, Given four starting symbols, symbol #3, symbol #7, and symbol #10, The first mini-time slot contains symbols #0 to #2, and the second mini-time slot contains symbols #1 to #2. The third mini-timeslot contains symbols #3 to #6, the third mini-timeslot contains symbols #7 to #9, and the fourth This indicates that the th mini-timeslot contains symbols #10 to #13. There are a number of consecutive mini-timeslots between each other.

[0149] In this case, the DCI signaling further indicates M RVs and the terminal's time domain resource In each mini-timeslot, PUSCH transmission is performed using the corresponding RV. Here, M is the number of hops in the time domain resource indicated by the DCI signaling. is the number of mini-timeslots. That is, multiple mini-timeslots are multiple PUSCs. When transmitting H, each mini-timeslot transmits one PUSCH, and the number of PUSCHs The number of mini-timeslots is the same as the number of sub-timeslots, and corresponds to each other one-to-one. In each mini-timeslot, PUSCH transmission is performed using the corresponding RV. .

[0150] The transmission content of each mini-timeslot contains the complete PUSCH data information, but each The redundancy version (RV) adopted in the data information corresponding to the mini-time slot is different. Due to LBT, the terminal does not necessarily know in which mini-time slot the channel is idle. For example, the channel number is not always detected before the last mini-time slot. If it detects that the module is idle, it will use the corresponding RV in the last mini-timeslot. The base station must transmit PUSCH using one mini-timeslot. By receiving the contents, the data information can be correctly decoded. If the channel is detected as idle before the start slot, the last three minutes The base station can transmit PUSCH using the corresponding RV in two timeslots. Then, the PUSCH data information of the received three mini-timeslots is combined and decoded. , the reception accuracy can be improved.

[0151] In the third case, the time domain resource is at least one time slot and at least one At most one mini-time slot, and the time domain resource scheduling method is as follows: Scheduling based on each time slot for at least one time slot and for at least one mini-time slot, and scheduling the same.

[0152] For this case, the start symbol of the time domain resource is at least one time slot. Each time slot or the first time slot of the For the first mini-timeslot or each mini-timeslot in a mini-timeslot The end symbol of the time domain resource is at least one time slot. Each time slot or the last time slot of and / or at least one mini-time slot For each mini-timeslot in a time slot, i.e., at least one For a time slot, the start symbol of a time domain resource shall be at least one time The end symbol is for the first time slot in the sequence, and the end symbol is at least or for the last time slot in one of the time slots, The start symbol of a time domain resource shall be the first symbol in at least one time slot. The end symbol is a time slot, and the end symbol is a time slot of at least one For each time slot, the start symbol of the time domain resource may be: For each time slot in at least one time slot, , the end symbol is for the last time slot in at least one time slot. and the start symbol of the time domain resource may be at least one time The stop symbol may be for each time slot in the system slot, It may be for each timeslot in at least one timeslot. For at least one mini-timeslot, the start symbol of the time domain resource is for each mini-timeslot in at least one mini-timeslot, The end symbol is present in each mini-timeslot in at least one mini-timeslot. The start symbol of the time domain resource may be the first symbol of at least one This is for the first mini-timeslot in the mini-timeslot, and the end symbol The rule is for each mini-timeslot in at least one mini-timeslot. may be also possible.

[0153] For example, a time domain resource may include four mini-timeslots and four time slots. where all four mini-timeslots are located in time slot #0, and four The time slots of #3 and time slot #4.

[0154] For four mini-timeslots, in one embodiment, the starting sequence of the time domain resource is The symbol is for the first mini-timeslot or for each mini-timeslot. The DCI signaling may further include the number of symbols contained in each mini-timeslot. The number of symbols contained in each mini-timeslot indicated by DCI signaling. may be the same or different.

[0155] For example, the start symbol of the time domain resource is for the first mini-timeslot. where DCI indicates the number of symbols and is for each mini-timeslot. In this case, the time domain resource is N consecutive mini-timers with the same number of symbols. For example, the start symbol of the first mini-timeslot is The data bit is symbol 0 and is included in each mini-timeslot indicated by DCI signaling. If the number of symbols included in each is 3, the first mini-timeslot will contain symbol # The first mini-timeslot contains symbols #0 to #2, the second mini-timeslot contains symbols #3 to #5, and the third mini-timeslot contains symbols #4 to #6. The second mini-timeslot contains symbols #6 through #8, and the fourth mini-timeslot contains symbols Indicates that #9~#11 are included.

[0156] For example, the start symbol of the time domain resource is the first mini-timeslot. The DCI indicates the number of symbols and In this case, the time domain resource is a set of N consecutive milliseconds with different numbers of symbols. For example, the first mini-timeslot is The starting symbol is symbol 0 and each mini-time slot indicated by DCI signaling If the number of symbols in the first mini-time slot is 2, 4, 4, and 4, respectively, The lot contains symbols #0 to #1, and the second mini-time slot contains symbols #2 to #5 The third mini-time slot contains symbols #6-#9, and the fourth mini-time slot contains symbols #7-#9. Indicates that the slot contains symbols #10 to #13.

[0157] Also, for example, the start symbol of the time domain resource is the same for each mini-timeslot. where DCI indicates the number of symbols and for each mini-timeslot. In this case, the time domain resource has N non-consecutive mini- For example, the start symbol of each mini-timeslot may be included. The bolts are symbol #0, symbol #3, symbol #7, and symbol #10, respectively. The number of symbols contained in each mini-timeslot indicated by the DCI signaling will eventually If the number is also 3, the first mini-timeslot contains symbols #0 to #2, and the second mini-timeslot contains symbols #1 to #2. The second mini-timeslot contains symbols #3 to #5, and the third mini-timeslot contains symbols #7~#9, and the fourth mini-timeslot contains symbols #10~#12. In this case, the second and third mini-time slots are consecutive. not separated by symbol #6.

[0158] Also, for example, the start symbol of the time domain resource is for each mini-timeslot. where DCI indicates the number of symbols and is for each mini-timeslot. In this case, the time domain resource is divided into N mini- tasks with different numbers of symbols and not consecutive. For example, the start symbol of each mini-time slot may be included. The symbols are symbol #0, symbol #3, symbol #7, and symbol #10, respectively, and The number of symbols contained in each mini-timeslot indicated by DCI signaling is If it is 2, 3, 3, 4, the first mini-timeslot contains symbols #0 to #1, The second mini-time slot contains symbols #3 through #5, and the third mini-time slot The fourth mini-timeslot contains symbols #7 to #9, and the fourth mini-timeslot contains symbols #10 to #13. It means to include.

[0159] For four mini-timeslots, in another embodiment, the start of the time domain resource The symbols may be for each mini-timeslot, in which case the Sth mini-timeslot The adjacent symbols before the start symbol of the time slot are the S-1th mini-time slot. is the end symbol of the lot. Here, S can have a value from 1 to M, where M is the time domain The number of mini-timeslots in a resource. For example, a time domain resource is one time slot. time slot, which in turn contains four mini-time slots. You only need to give the start symbol for the 4 mini-time slots, and the second mini-time slot The adjacent symbol before the start symbol of the first mini-timeslot is the end symbol of the first mini-timeslot. symbol and the adjacent symbol before the start symbol of the third mini-timeslot. is the end symbol of the second mini-timeslot and the start symbol of the fourth mini-timeslot. The adjacent symbol before the start symbol is the end symbol of the third mini-timeslot. be.

[0160] For example, only a number of starting symbols are given for the time domain resource, e.g. Four starting symbols are given: symbol #0, symbol #3, symbol #7, and symbol #10. If the first mini-timeslot contains symbols #0 to #2, the second mini-timeslot contains symbols #1 to #2, and the The first mini-time slot contains symbols #3-#6, and the third mini-time slot contains symbols #7- #9, and the fourth mini-timeslot contains symbols #10 through #13. In this case, multiple mini-timeslots are consecutive.

[0161] For four mini-timeslots, in another embodiment, the start of the time domain resource The symbols may be for each mini-timeslot and may be the end of the time domain resource. An end symbol may be for each mini-timeslot. In this case, the time domain A resource may contain N non-contiguous mini-timeslots with different numbers of symbols. For example, the start symbols of each mini-timeslot are symbol #0, Symbol #3, Symbol #7, and Symbol #10 are the end symbols of each mini-timeslot. If the bol is symbol #1, symbol #5, symbol #9, or symbol #13, The first mini-time slot contains symbols #0 to #1, and the second mini-time slot The first mini-timeslot contains symbols #3 to #5, and the third mini-timeslot contains symbols #7 to #9. This indicates that the fourth mini-timeslot contains symbols #10 to #13.

[0162] For four time slots, in one possible implementation, the start of the time domain resource There may be only one symbol.

[0163] For example, a time domain resource contains four time slots and the start symbol is symbol # 7, for the first time slot only, with the end symbol being symbol #8 , if it is for the 4th time slot only, the first time slot's synchronisation All time domain resources between symbol #7 and symbol #8 of the 4th time slot are , is a time domain resource allocated to a terminal for PUSCH transmission, and specifically, Symbol #7 to #13 in the first time slot, and #1 in the second time slot. Symbol #0 to Symbol #13, 3rd time slot Symbol #0 to Symbol #13 , and includes symbols #0 to #8 of the fourth time slot.

[0164] For example, the time domain resource includes four time slots and the start symbol is a single The first symbol is symbol 0 for each time slot, the second symbol is symbol 6 for each time slot, and the third symbol is symbol 7 for each time slot. For a time slot, symbols #0 to #6 of each time slot are , is a time domain resource allocated to a terminal for PUSCH transmission, and specifically, Symbol #0 to #6 in the first time slot, Symbol #1 in the second time slot Symbol #0 to Symbol #6 of the third time slot, Symbol #0 to Symbol #6 and 4 Includes symbols #0 to #6 of the th time slot.

[0165] For example, the time domain resource includes four time slots and the start symbol is a single Boolean #7 is for the first time slot only and the end symbol is symbol #12, for each time slot, the symbol for the first time slot time slot #7 to symbol #12, the second time slot #0 to symbol #12, Symbol #0 to #12 of the 1st time slot and Symbol #12 of the 4th time slot Symbols #0 to #12 are the time domains assigned to the terminal for PUSCH transmission. It is a regional resource.

[0166] For example, the time domain resource includes four time slots and the start symbol is a single for each time slot with the end symbol being symbol #12, If it is for the last timeslot only, the symbol in the first timeslot #7~symbol #13, the second time slot's symbol #7~symbol #13, the third time slot's symbol #7~symbol #13 Symbols #7 to #13 in the first time slot and #14 in the fourth time slot Symbols #7 to #12 are the time domains assigned to the terminal for PUSCH transmission. It is a resource.

[0167] In another possible implementation, the development of time domain resources for four time slots is The start symbol may be multiple, and the multiple start symbols are Alternatively, multiple start symbols for each time slot may be used. For example, one time slot has 14 symbols and two If the start symbols of a symbol are specified as symbol #0 and symbol #7, multiple start symbols are If the rule is for the first time slot only, then only the first time slot It has two start symbols, symbol #0 and symbol #7, and the start symbols of other time slots All symbols are symbol #0, and multiple start symbols are assigned to each time slot. Then, each time slot has two start symbols, symbol #0 and symbol #7. A time slot with two starting symbols, for example symbol #0 and symbol #7. For a channel, the terminal detects that the channel is idle before symbol #0. If the terminal transmits complete PUSCH data information, the terminal will tune before symbol #0. Does not detect that the channel is idle and the channel becomes idle before symbol #7 If the terminal detects that the symbol is a 0, the terminal will start from symbol #7 through the end symbol, e.g. Only data mapped up to #13 can be transmitted, and data mapped to symbols #0 to #6 The data cannot use the channel, so it is deleted (punctured). There is nothing else I can do.

[0168] In this case, the DCI signaling further includes K RVs and the terminal's time domain resource Using the corresponding RVs in each time slot and mini time slot Here, K is the time period indicated by the DCI signaling. The number of time slots and mini-time slots in the area resource. A time slot or mini-time slot transmits one PUSCH, and a time slot and The number of mini-timeslots and PUSCHs is the same, and the terminal uses the time domain resource Using the corresponding RVs in each time slot and mini time slot Perform PUSCH transmission.

[0169] Each timeslot or mini timeslot transmits a complete PUSCH data stream. Considering that the information is included, the terminal does not necessarily know which time slot or mini Listening to a channel in a timeslot is not necessarily idle, e.g. If the channel is heard to be idle only before the last time slot In this case, PUSCH transmission is required only in the last time slot, and the base station By receiving the contents of the time slot, the data information can be correctly decoded. Before the last mini-timeslot and four time slots, the channel is idle. If it detects that there is a PUSCH in the last time slot and the next four time slots, The base station can transmit one mini-timeslot and four time slots received. Combining and decoding the PUSCH data information of the slots improves reception accuracy. Can

[0170] In another possible implementation, the PUS in each time slot or mini-time slot The position near the start symbol of the CH transmission is the transmission start position of the PUSCH. There are several types of transmission start positions:

[0171] The first type is the start of PUSCH transmission in each timeslot or mini timeslot. The start symbol is the transmission start position of the PUSCH.

[0172] The second type is the start of PUSCH transmission within each timeslot or mini timeslot. The position of a predetermined time after the first symbol is the transmission start position of the PUSCH. The time is set by the base station and may be 25 μs, 30 μs, etc.

[0173] The third type is the start of PUSCH transmission within each timeslot or mini timeslot. The position after the first symbol, which is a predetermined time plus TA, is the transmission start position of the PUSCH. do.

[0174] The fourth type is the start of PUSCH transmission within each timeslot or mini timeslot. The start position of the adjacent symbol after the first symbol is the transmission start position of the PUSCH. .

[0175] If the start symbol is i, the transmission start position of the PUSCH is a) Symbol i b) 25μs in Symbol i c) (25+TA) μs in Symbol i d) Symbol i+1 may be also possible.

[0176] In order to easily distinguish different transmission start positions of the PUSCH, the base station You can set a different identifier for each device, so that the device can detect Specifically, the start position of PUSCH transmission can be determined. Set identifier 00 to the start symbol and transmit a PUSCH transmission at a predetermined time after the start symbol. Set identifier 01 at the position, and set TA at a predetermined time after the start symbol of PUSCH transmission. The identifier 10 is set at the position where the symbol is added, and the adjacent symbol after the start symbol of the PUSCH transmission is added. An identifier 11 can be set at the start position of the symbol.

[0177] For example, i may be 0, and the transmission start position of the PUSCH may be as shown in Table 1. [Table 1]

[0178] Also, for example, i may be 7, and the transmission start position of the PUSCH may be as shown in Table 2. [Table 2]

[0179] The start symbol may be any one of symbols 0 to 13. Considering the large number of start symbols, in order to reduce the number of start symbols in the transmission, You can specify the symbol of the first symbol, for example, symbol 0, symbol 2, symbol 4. , symbol 7, symbol 8, symbol 9 or symbol 11. The symbols in the rule may be up to 13 symbols.

[0180] In step S402, the terminal receives DCI signaling transmitted from the base station. do.

[0181] In step S403, the terminal determines whether to transmit a PUSCH based on the DCI signaling. conduct.

[0182] Before transmitting PUSCH based on DCI signaling, the terminal performs LBT listening. The cut-off position for LBT listening must be determined. The end of the time slot is the last LBT listening position, and the position is the last time slot. It is before the start symbol of the last timeslot or mini timeslot. The channel is found to be idle prior to the start symbol of the time slot. If the channel is not listened to, i.e. the channel is constantly busy, the LBT list There is no need to continue scanning the channel after it has been idle. Even if the PUSCH is sniffed, there is no complete transmission time unit at this time, so no PUSCH transmission is performed. Because it is not possible.

[0183] The terminal obtains the LBT listening cutoff position in the following two ways. It is possible.

[0184] In one possible implementation, the terminal is capable of receiving control signaling transmitted from a base station. The control signaling is sent when the terminal performs listen-before-talk (LBT) listening. The control signaling indicates the cutoff position. e Control, Radio Resource Control) signaling, MAC signaling (Medi a Access Control, Media Access Control, and DCI signaling The present invention includes one or more combinations of the above.

[0185] In another possible implementation, the terminal chip has a cutoff position for LBT listening. Since the chip is pre-stored, the terminal can determine the cutoff position for LBT listening from the chip. It can be obtained.

[0186] Based on the obtained LBT listening cutoff position, different time domain resources The method by which the terminal performs LBT listening also differs from the scheduling method.

[0187] In one possible implementation, the time domain resource is at least one time slot. The time domain resource scheduling scheme schedules based on each time slot. If the LBT listening cutoff position is the last time slot, In this case, the terminal (There is no specific limit as to how far in advance) Starts BT listening and switches to LBT listening by the start symbol of the last time slot. If the channel becomes idle before the start symbol of the last timeslot, If the terminal listens for a RV in the last time slot, it will use the corresponding RV. Then, PUSCH transmission is performed, and the channel is If the device is busy, LBT listening will not be performed.

[0188] In another possible implementation, the time domain resource is at least one mini-time slot. The scheduling method of time domain resources is based on each mini-timeslot. If the schedule is to be made, the cutoff position for LBT listening is the last minute. In this case, the terminal Start LBT listening before the start symbol of the music slot and LBT listening until the start symbol of the lot, and the start of the last mini-time slot If the terminal hears the channel idle before the symbol In the last mini-timeslot, the PUSCH transmission is performed using the corresponding RV, and The channel remains busy until the start symbol of the next mini-timeslot. If you listen to this, you will no longer listen to LBT.

[0189] In another possible implementation, the start symbol is any one of symbols 0 to 13. Considering the number of start symbols of transmission, it may be one. To reduce the number of symbols, the symbol of the start symbol can be limited, e.g. symbol #0, symbol #2, symbol #4, symbol #7, symbol #8, symbol #9 or Symbol #11, etc. The end symbol is limited to a maximum of symbol #13.
