For example, a slot format may include 14 OFDM symbols, or a slot format may include 12 OFDM symbols; alternatively, one slot format is to contain 7 OFDM symbols. The OFDM symbols in one slot may be all used for uplink transmission; can be used for downlink transmission; and a part of the time domain symbols can be used for downlink transmission, a part of the time domain symbols can be used for uplink transmission, and a part of the time domain symbols can be flexibly configured to be used for uplink or downlink transmission. It should be understood that the above examples are illustrative only and should not be construed as limiting the present application in any way.

The foregoing has described some of the noun concepts to which embodiments of the present application relate, and the following has described some features of the embodiments of the present application.

To enhance the uplink coverage performance of NR, TBoMS PUSCH techniques are proposed. The technique aggregates small packets on each slot into one large packet and completes the transmission of this large packet over multiple slots. Packet header overhead can be reduced through packet aggregation, cyclic redundancy code overhead can be reduced by reducing the number of times of dividing a Transport Block (TB), coding gain can be improved by increasing the size of the Transport Block (TBs), power spectral density can be improved by reducing the number of Physical Resource Blocks (PRBs), and finally the purpose of enhancing NR uplink coverage performance is achieved.

Currently, the TDRA for TBoMS transmission may multiplex a repeat type a TDRA (repetition type impact TDRA). I.e., the TBoMS uses the same symbol allocation on each slot. The start symbol and length of each slot may be indicated by a Start and Length Indicator Value (SLIV) (start symbol and length field) and/or a start symbol S (start symbol field) and length L (length field) in a TDRA table. Currently, when a symbol indicated by SLIV (or starting symbol S, length L) includes a downlink symbol, a slot in which the symbol is located cannot be used for PUSCH transmission. And a special timeslot generally includes three parts, which are downlink symbols, flexible symbols, and uplink symbols in sequence. Therefore, the problem that the transmission blocks transmitted by crossing time slots can only be transmitted by utilizing the uplink time slots is solved, and the uplink coverage performance is poor.

Based on this, embodiments of the present application provide a communication method and apparatus, so as to solve the problem that a transmission block transmitted across time slots can only be transmitted by using an uplink time slot, and uplink coverage performance is poor. The method and the device are based on the same inventive concept, and because the principles of solving the problems of the method and the device are similar, the implementation of the device and the method can be mutually referred, and repeated parts are not repeated.

In the embodiments of the present application, "in the case of … …", "if … …", "if", "when … …", and the like are described interchangeably. For example, "in the case where the first symbol does not include a symbol for downlink transmission," may also be described as "if the first symbol does not include a symbol for downlink transmission," or "if the first symbol does not include a symbol for downlink transmission" or "when the first symbol does not include a symbol for downlink transmission," or the like.

In addition, in the following embodiments, repeated transmission, or repeated transmission of the uplink transport block is referred to multiple times, and a person skilled in the art should understand the meaning of the repeated transmission, or repeated transmission of the uplink transport block. And repeatedly sending, repeatedly transmitting or repeatedly sending the uplink transport blocks, wherein the uplink transport blocks are all used for indicating that one uplink transport block needs to be sent one time or multiple times. The embodiment of the present application does not limit whether the content sent each time is completely the same. For example, in actual communications, the RV for each transmission may be different. In addition, in the present application, the "uplink transport block" may be replaced by "transport block" or "data block" or "uplink data", etc., or in future protocols, names used for indicating the same or similar meanings are all applicable to the embodiments of the present application.

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

Referring to fig. 2, a flow chart of a communication method provided in the present application is schematically illustrated. The method comprises the following steps:

s201, the network device sends a first signaling to the terminal device. Accordingly, the terminal device receives the first signaling from the network device.

The first signaling is used to indicate a TDRA of an uplink transport block, where the uplink transport block may be sent in multiple time slots, for example, the uplink transport block is a TBoMS. In particular, the first signaling may indicate a first symbol including at least one symbol and a second symbol including at least one symbol.

Optionally, the first symbol and the second symbol are distinguished by at least one of: different starting symbols and different lengths.

For example, the first signaling may indicate a first start symbol and a first length, wherein the first start symbol is a first symbol in a first slot allocated to the uplink transport block, and the first length is a number of symbols in the first slot allocated to the uplink transport block. From the first starting symbol S1 and the first length L1, a first symbol of length L1 starting from the symbol S1 can be determined. For example, the first signaling may carry at least one of the following parameters: a first SLIV, a first starting symbol, or a first length, wherein the first SLIV may indicate the first starting symbol and the first length.

It is to be understood that the above manner of indicating the first symbol is to take the first start symbol and the first length as an example, in a specific implementation, the first signaling may also indicate the first symbol through the first end symbol and the first length, or may also indicate the first symbol through the first start symbol and the first end symbol, and so on.

It should be noted that the first start symbol, the first end symbol or the first length may also be default, for example, the first start symbol defaults to the first symbol in the slot, the first end symbol defaults to the last symbol in the slot, the first length defaults to 7 symbols, and so on.

The indication mode of the second symbol is similar to that of the first symbol, and repeated descriptions are omitted.

In addition, the first signaling may further indicate a starting time slot and a first number of time slots, where the first number of time slots indicates the number of time slots allocated to consecutive time slots of the uplink transport block, that is, the first number of time slots indicates the number of physical time slots allocated to the uplink transport block. By the method, the time domain resource range can be divided in advance, and the method is simpler to implement.

Alternatively, the first signaling may further indicate a starting time slot and a second number of time slots, where the second number of time slots indicates the number of time slots of the plurality of time slots used for transmitting the uplink transport block, that is, the second number of time slots indicates the number of available time slots of the uplink transport block. By the method, the transmitted uplink transmission block can carry complete information, and the reliability and the coverage performance are better.

In an exemplary illustration, the candidate value for the first number of slots may be, but is not limited to: 1,2,3,4,7,8,12,16, 20, 24, 28, 32, 34, 36, 40, 42, etc.

The candidate value for the second number of slots may be, but is not limited to: 1,2,3,4,7,8,12,16, 20, 24, 28, 32, 34, 36, 40, 42, etc.

It should be understood that the first number of time slots and the second number of time slots are merely illustrated here, and the candidate values of the first number of time slots and the second number of time slots are not limited to be the same, and in a specific implementation, the candidate values of the first number of time slots and the second number of time slots may include others or some of the above examples, and are not limited here.

Through the above manner, the terminal device can determine the time slot for sending the uplink transport block.

Optionally, if the uplink transport block is sent in a manner of repeat transmission (for example, repeat type a), the first signaling may further indicate a repeat interval, where the repeat interval is used to indicate a time interval between two adjacent repeats. Specific indications of the repetition interval are provided below. The first signaling may also indicate a number of repetitions of the uplink transport block.

Example one, the repetition interval may indicate a time interval between start slots of two adjacent repeated transmissions.

For example two, the repetition interval may indicate a time interval between a last slot of the plurality of slots configured for a previous repeated transmission and a start slot of a subsequent repeated transmission in two adjacent repeated transmissions.

For example three, the repetition interval may indicate a time interval between a last time slot for uplink transmission in a previous repetition transmission and a starting time slot of a next repetition transmission in two adjacent repetition transmissions.

The unit of the time interval may be a timeslot, or a third time unit, or a mini-timeslot, or a subframe, or a half-frame, or a frame, or an uplink and downlink timeslot matching period, or a millisecond, where the third time unit may refer to the related description about the TOT in the foregoing description. For convenience of description, the third time unit will be referred to as TOT hereinafter.

In a possible implementation, when the first signaling indicates the first number of slots, the repetition interval may be example one, example two, or example three. The repetition interval may be example one or example three when the first signaling indicates the second number of slots.

The content of the indication of the first signaling is introduced above, and the signaling design of the first signaling is exemplified below. It should be understood that the following examples are only given as examples where the first signaling includes the various parameters mentioned above, and the first signaling is not limited to include all the parameters in the following examples.

The first signaling may be Radio Resource Control (RRC) signaling. The first signaling may indicate the TDRA of the uplink transport block through a TDRA table (PUSCH-TimeDomainResourceAllocationList) in the RRC signaling. Two possible TDRA tables are presented below.

Example one, a PUSCH allocation table (PUSCH allocation list table) is included in the TDRA table, where the PUSCH allocation table includes at least one of the following fields: slotNum, startSymbolAndLength, startSymbol, length, startSymbolAndLength2, startSymbol2, length2, intervalOfRepetitions, wherein slotNum is used for indicating the first slot number or the second slot number, startSymbolAndLength is used for indicating the first SLIV, startSymbol is used for indicating the first start symbol, length is used for indicating the first Length, startSymbolAndLength2 is used for indicating the second SLIV, startSymbol2 is used for indicating the second start symbol, length2 is used for indicating the second Length, and intervalOfRepetitions is used for indicating the repetition interval. The PUSCH allocation table may further include other fields, such as a k2 field indicating a starting slot, a mappingType field indicating a mapping manner of the DMRS in the first type slot, a numberOfRepetitions field indicating the number of repetitions, and the like, which are not listed here.

For example, the TDRA table includes k2 and a PUSCH allocation table, wherein the PUSCH allocation table includes mappingType, slotNum, startSymbol and Length, startSymbol, length, startSymbol and Length2, startSymbol2, length2, numberOfRepetitions, and intervalOfRepetitions.

In the above example, by adding fields such as slotNum, startSymbol andlength2, startSymbol2, length2, intervalOfRepetitions, etc., the first signaling may indicate information such as the second symbol, the repetition interval, the number of slots, etc.

Example 2, a PUSCH allocation table (PUSCH allocation list table) is included in the tdra table, the PUSCH allocation table including at least one of the following fields: startSymbol andlength, startSymbol, length, startSymbol andlength2, startSymbol2, length2, and numberOfRepetitions, wherein numberOfRepetitions may indicate the first slot number or the second slot number, startSymbol andlength is used to indicate the first SLIV, startSymbol is used to indicate the first start symbol, length is used to indicate the first Length, startSymbol andlength2 is used to indicate the second SLIV, startSymbol2 is used to indicate the second start symbol, and Length2 is used to indicate the second Length. The PUSCH allocation table may further include other fields, such as a k2 field indicating a starting slot, a mappingType field indicating a mapping manner of the DMRS in the first type slot, and so on, which are not listed here.

By way of illustration, the TDRA table includes k2 and a PUSCH allocation table, wherein the PUSCH allocation table includes mappingType, startSymbolAndLength, startSymbol, length, startSymbolAndLength2, startSymbol2, length2, and numberOfRepetitions.

In the above example, the number of slots is indicated by multiplexing the numberOfRepetitions field, so that the signaling overhead can be reduced.

It should be noted that the second example can be applied to a scenario that does not support repeated transmission.

In addition, the first signaling may also indicate a mapping manner of the DMRS in the second-type slot. For example, the PUSCH allocation table of the first signaling may include a mappingType2 field, which may indicate a mapping manner of the DMRS in the second type slot.

It should be noted that, the manner of mapping the DMRS in the second type of slot is indicated in the first signaling is only one possible implementation. In a specific implementation, the mapping manner of the DMRS in the second-type slot may also be determined in other manners, for example, the mapping manner of the DMRS in the second-type slot may also be default, for example, the mapping manner of the DMRS in the second-type slot may default to MappingTypeB.

S202, the terminal equipment determines the time domain resource for sending the uplink transmission block based on the first signaling.

In some embodiments, the determining, by the terminal device, the time domain resource for transmitting the uplink transport block based on the first signaling may include: and determining a time slot for sending the uplink transmission block and a time domain resource for sending the uplink transmission block in each time slot.

Here, the time domain resource for transmitting the uplink transport block in each time slot is first described.

In one implementation, the time slots meet different conditions, and the time domain resources used for transmitting the uplink transport block on the time slots are different. Three examples of time domain resources for transmitting the uplink transport block in a time slot under different conditions are described below.

For example 1, if the first symbol in the slot does not include the downlink symbol, the time domain resource of the uplink transport block includes the first symbol in the slot. Or, if the first symbol in the slot includes the downlink symbol and the second symbol in the slot does not include the downlink symbol, the time domain resource of the uplink transport block includes the second symbol in the slot and does not include the first symbol in the first slot.

Based on the above example, the terminal device may determine, according to the first signaling, that the time domain resource for sending the uplink transport block includes at least one of the following: a second symbol in the first slot, or a first symbol in the second slot.

The first symbol in the first time slot includes a downlink symbol, and the second symbol in the first time slot does not include a downlink symbol. The first symbol in the second slot does not include a downlink symbol.

For example 2, if the first symbol in the slot does not include the downlink symbol, and the second symbol in the slot does not include the downlink symbol, the time domain resource of the uplink transport block includes the first symbol in the slot. Or, if the first symbol on the slot includes a downlink symbol and the second symbol on the slot does not include the downlink symbol, the time domain resource of the uplink transport block includes the second symbol on the slot.

In an example, the time slots 1 to 5 are taken as an example, where the time slots 1 to 2 each include 14 downlink symbols, the symbols 0 to 7 in the time slot 3 are downlink symbols, the symbols 8 to 13 are uplink symbols, and the time slots 4 to 5 each include 14 uplink symbols. Assume that the first signaling indicates that the first symbol is 0 to 11 and the second symbol is 10 to 13. For the time slot 1 and the time slot 2, the first symbol and the second symbol both include downlink symbols, and there is no time domain resource for transmitting the uplink transport block on the time slot 1 and the time slot 2. For the time slot 3, the first symbol includes a downlink symbol, the second symbols are uplink symbols, and the symbols 10 to 13 in the time slot 3 are time domain resources for transmitting an uplink transport block. For the time slot 4 and the time slot 5, the first symbol is an uplink symbol, and the symbols 0 to 11 in the time slot 4 and the time slot 5 are time domain resources for transmitting an uplink transport block. As shown in fig. 3.

Based on the above example, the terminal device may determine, according to the first signaling, that the time domain resource for transmitting the uplink transport block includes at least one of the following: the second symbol in the third slot, or the first symbol in the fourth slot.

The first symbol in the third slot includes a downlink symbol, and the second symbol in the third slot does not include a downlink symbol. The first symbol in the fourth slot does not include a downlink symbol, and the second symbol in the fourth slot does not include a downlink symbol.

For example, 3, if the first symbol in the time slot does not include the downlink symbol, the second symbol in the time slot does not include the downlink symbol, and the number of symbols in the first symbol in the time slot is greater than the number of symbols in the second symbol in the time slot, the time domain resource of the uplink transport block includes the first symbol in the time slot.

Or, if the first symbol in the timeslot does not include the downlink symbol and the second symbol in the timeslot includes the downlink symbol, the time domain resource of the uplink transport block includes the first symbol in the timeslot.

Or, if the first symbol in the timeslot does not include the downlink symbol, and the second symbol in the timeslot does not include the downlink symbol, and the number of symbols in the first symbol in the timeslot is not more than the number of symbols in the second symbol in the timeslot, the time domain resource of the uplink transport block includes the second symbol in the timeslot.

Or, if the first symbol in the timeslot includes a downlink symbol and the second symbol in the timeslot does not include a downlink symbol, the time domain resource of the uplink transport block includes the second symbol in the timeslot.

Based on the above example, the terminal device may determine, according to the first signaling, that the time domain resource for transmitting the uplink transport block includes at least one of the following: the first symbol in the fifth slot, or the first symbol in the sixth slot, or the second symbol in the seventh slot, or the second symbol in the eighth slot.

The first symbol on the fifth slot does not include a downlink symbol, the second symbol on the fifth slot does not include a downlink symbol, and the number of symbols of the first symbol on the fifth slot is greater than the number of symbols of the second symbol on the fifth slot.

The first symbol on the sixth slot does not include a downlink symbol and the second symbol on the sixth slot includes a downlink symbol.

The first symbol on the seventh slot does not include a downlink symbol and the second symbol on the seventh slot does not include a downlink symbol, and the number of symbols of the first symbol on the seventh slot is no more than the number of symbols of the second symbol on the seventh slot.

The first symbol on the eighth slot includes a downlink symbol and the second symbol on the eighth slot does not include a downlink symbol.

Optionally, based on example 3 above, the first signaling may indicate a mapping manner of the DMRS in the first-type slot and a mapping manner of the DMRS in the second-type slot. For example, the first signaling may include a mappingType field and a mappingType2 field, where the mappingType field indicates a mapping manner of the DMRS in the first type of slot, and the mappingType2 field indicates a mapping manner of the DMRS in the second type of slot.

In the above three examples, whether the time domain resource for transmitting the uplink transport block in the slot is the first symbol or the second symbol is determined according to whether the downlink symbol is included in the first symbol and the second symbol. Based on the above three examples, an optional scheme is further provided, that when determining that the time domain resource for transmitting the uplink transport block in the timeslot is the first symbol, in addition to satisfying the corresponding conditions in the above three examples, the following is also satisfied: if the time slot has downlink symbols, and the interval between the last downlink symbol and the first uplink symbol of the first symbol is not less than GP. In this scheme, if a slot satisfies the condition satisfied by the second slot, the fourth slot, the fifth slot, or the sixth slot, and the slot has a downlink symbol, and the interval between the last downlink symbol and the first uplink symbol of the first symbol is not less than GP, it may be determined that the time domain resource for transmitting the uplink transport block in the slot is the first symbol. If the time slot satisfies the condition satisfied by the second time slot, or the fourth time slot, or the fifth time slot, or the sixth time slot, but the time slot has a downlink symbol, and the interval between the last downlink symbol and the first uplink symbol of the first symbol is less than GP, it may be determined that the time domain resource for transmitting the uplink transport block in the time slot is the second symbol.

It should be noted that, in the above three examples, only whether the first symbol includes a downlink symbol and/or whether the second symbol includes a downlink symbol is taken as an example to determine whether the time domain resource used for transmitting the uplink transport block in the timeslot is the first symbol or the second symbol. In a specific implementation, it is also possible to determine whether the first symbol includes at least one of: whether the downlink symbol, the flexible symbol, the Guard Period (GP), and/or the second symbol includes at least one of: a downlink symbol, a flexible symbol, and a GP, to determine whether a time domain resource for transmitting the uplink transport block on a timeslot is a first symbol or a second symbol.

In order to distinguish between a slot for transmitting an uplink transport block using a first symbol and a slot for transmitting an uplink transport block using a second symbol, a slot for transmitting an uplink transport block using a first symbol will be referred to as a first type slot and a slot for transmitting an uplink transport block using a second symbol will be referred to as a second type slot hereinafter. It should be understood that the time slots are classified according to the conditions satisfied, which is only for the purpose of distinction.

The time domain resource for transmitting the uplink transport block in each time slot is introduced above, and the method for determining the time slot for transmitting the uplink transport block is described below.

As described above, the first signaling may indicate the starting time slot and the first number of time slots, or indicate the starting time slot and the second number of time slots. Here, a method for determining a time slot for transmitting the uplink transport block by the terminal device will be described with reference to the first time slot number N and the second time slot number M.

In the embodiment where the first signaling indicates the starting timeslot and the first number of timeslots N, the terminal device may determine the timeslot for transmitting the uplink transport block according to the above three examples, where the first consecutive timeslot starts from the starting timeslot indicated by the first signaling and has a length equal to the first number of timeslots N.

It should be understood that the time slot for transmitting the uplink transport block and the time domain resource for transmitting the uplink transport block in each time slot may be determined by an implementation process, which is as follows, as shown in fig. 4, taking the above example 1 as an example:

s401, determining a first symbol on the slot n according to the first signaling. S402 is performed.

Wherein, the initial value of n is the index of the starting time slot of the first signaling indication.

S402, determining whether the first symbol includes a symbol for downlink transmission. If so, go to S403, otherwise, go to S407.

S403, determining a second symbol on the slot n according to the first signaling. S404 is performed.

S404, determining whether the second symbol includes a symbol for downlink transmission. If yes, go to step S405, otherwise, go to step S408.

S405, judging whether the value of N is less than (N + N-1). If yes, go to step S406. If not, the process is ended.

S406, adding 1 to the value of n. S401 is performed.

S407, determining that the time domain resource for transmitting the uplink transport block includes the first symbol in the time slot n. S405 is executed.

S408, it is determined that the time domain resource for transmitting the uplink transport block includes the second symbol in the time slot n. S405 is executed.

The time slot for transmitting the uplink transport block and the time domain resource for transmitting the uplink transport block in each time slot can be determined through the process shown in fig. 4.

In the method shown in fig. 4, the first type time slot and the second type time slot in the first continuous time slot are used as time slots for sending uplink transport blocks, but in a specific implementation, some first type time slots/second type time slots may exist in the first transport time slot and are preempted by other high-priority signals or channels, so that the terminal device may exclude these time slots when determining the time domain resources.

For example, assuming that the uplink and downlink timeslot configuration period "DDDSUDDSUU", where the starting timeslot is the first timeslot, N =10, i.e. 10 timeslots are allocated to the uplink transport block, the downlink timeslot is removed and the second uplink timeslot is preempted by other high-priority signals or channels, and the uplink transport block actually uses 4 timeslots, as shown in fig. 5.

In the embodiment where the first signaling indicates the starting time slot and the second number M of time slots, the terminal device may determine M time slots for transmitting the uplink transport block according to the above three examples, starting from the starting time slot indicated by the first signaling, and add 1 to the counter. Otherwise, continuing to judge the next time slot until the value of the counter is equal to the second time slot number M. Through the method, M time slots for sending the uplink transmission blocks can be determined.

It should be understood that the time slot for transmitting the uplink transport block and the time domain resource for transmitting the uplink transport block in each time slot may be determined by an implementation process, for example, as shown in fig. 6, the implementation process may be as follows:

s601, determining a first symbol in the time slot n according to the first signaling. S602 is performed.

S602, determine whether the first symbol includes a symbol for downlink transmission. If so, go to S603, otherwise, go to S607.

S603, determining a second symbol on the slot n according to the first signaling. S604 is performed.

S604, determining whether the second symbol includes a symbol for downlink transmission. If so, go to S605, otherwise, go to S608.

S605, judge whether the value of the counter is less than (M-1). If yes, go to S606. If not, the process is ended.

Wherein the initial value of the counter is 0.

And S606, adding 1 to the value of n. S601 is executed.

S607, it is determined that the time domain resource for transmitting the uplink transport block includes the first symbol in the time slot n, and the counter is incremented by 1. S605 is executed.

S608, it is determined that the time domain resource for transmitting the uplink transport block includes the second symbol in the time slot n, and the counter is incremented by 1. S605 is executed.

The time slot for transmitting the uplink transport block and the time domain resource for transmitting the uplink transport block in each time slot can be determined through the process shown in fig. 6.

In the method shown in fig. 6, the determined first class time slot and the second class time slot are used as time slots for sending uplink transport blocks, but in a specific implementation, the determined first class time slot/second class time slot may be preempted by other high-priority signals or channels, and therefore, the terminal device may exclude these time slots when determining the time domain resources.

For example, assume an uplink and downlink timeslot configuration period "DDDSUDDSUU", where the starting timeslot is the first timeslot, N =5, that is, the uplink transport block actually uses 5 timeslots, the downlink timeslot is removed, and a second uplink timeslot is preempted by other high-priority signals or channels, and in order to ensure that the number of timeslots actually used by the uplink transport block is 5, the first S timeslot in the second uplink and downlink timeslot configuration period is also used for the uplink transport block, as shown in fig. 7.

S203, the network device determines, based on the first signaling, a time domain resource for sending the uplink transport block.

The method for determining the time domain resource by the network device is the same as that of the terminal device, and reference may be specifically made to S202, which is not repeated herein.

It should be noted that steps S202 and S203 are not performed in a strict time sequence.

And S204, the terminal equipment sends the uplink transmission block on the determined time domain resource. Accordingly, the network device receives the uplink transport block on the determined time domain resource.

The specific transmission method will be described in detail below.

In the embodiment of the application, the terminal device can effectively distinguish the uplink time slot and the special time slot through the first signaling, and can independently indicate the time domain resources in the uplink time slot and the special time slot, so that the special time slot can be effectively utilized to send the uplink transmission block, the resource utilization rate can be improved, and the transmission efficiency can be improved.

The following describes a process of the terminal device sending the uplink transport block on the determined time domain resource.

In a possible implementation manner, when the terminal device sends the uplink transport block on the determined time domain resource, the terminal device may determine an information bit amount corresponding to the uplink transport block, and determine an uplink signal corresponding to the uplink transport block according to the information bit amount. And the terminal equipment transmits the uplink signal on the time domain resource.

The information bit amount may be determined according to a parameter K for scaling, where K is a ratio of a resource corresponding to a first time unit to a resource corresponding to a second time unit in the uplink transport block.E.g. the amount of information bits N _info The following formula may be satisfied or may be understood as being determined by the following formula:

N _info ＝K·N _RE ·R·Q _m ·v；

wherein N is _RE Is the number of Resource Elements (REs) in the second time unit, R represents the code rate, Q _m Denotes the order of modulation and v denotes the number of layers.

The resource corresponding to the first time unit refers to a resource used for sending the uplink transport block in the resource corresponding to the first time unit, and the resource corresponding to the second time unit refers to a resource used for sending the uplink transport block in the resource corresponding to the second time unit.

The resource may refer to a symbol number (a symbol number of a first symbol or a symbol number of a second symbol), a symbol number obtained by dividing a symbol of a DMRS, or a number N 'of REs in one PRB' _RE Or total number of REs, etc.

Several possible definitions of the first time unit and the second time unit are presented below.

The first time unit may be at least one of: the longest TOT among the TOTs for transmitting the uplink transport block, or the shortest TOT among the TOTs for transmitting the uplink transport block, or a plurality of TOTs among the TOTs for transmitting the uplink transport block, or all slots for transmitting the uplink transport block.

The second time unit may be at least one of: the first type of time slot, or the second type of time slot, or the first TOT used for transmitting the uplink transport block (i.e. the first available TOT), or the first time slot used for transmitting the uplink transport block (i.e. the first available time slot), or the longest TOT among the TOTs used for transmitting the uplink transport block, or the shortest TOT among the TOTs used for transmitting the uplink transport block.

For example, it is assumed that the ratio of the uplink and downlink timeslots is "DDDSUDDSUU", the number of timeslots allocated by the uplink transport block is N =15, and the starting timeslot is the first downlink timeslot, as shown in fig. 8. Assume that the uplink transport block includes three TOTs, where the first TOT is the first two "SU" slots, the second TOT is the middle three "SUU" slots, and the third TOT is the last two "SU" slots.

If the first time unit is the shortest TOT among the TOTs for transmitting the uplink transport block, the first time unit is the first TOT or the third TOT in fig. 8, and so on, which will not be described one by one here.

If the second time unit is the first available time slot, the second time unit is the first special time slot of fig. 8, etc., and the description thereof will not be repeated.

To facilitate understanding of the scheme, the definition of K is explained below by aggregating various examples of the first time unit, the second time unit, and the resource. Exemplary, as shown in table 1.

TABLE 1

Wherein L and L2 represent a first symbol length and a second symbol length, respectively, L _DMRS And L2 _DMRS Respectively represents the DMRS symbol number on the first type time slot and the DMRS symbol number, N 'on the second type time slot' _RE And

respectively representing the number of REs in one PRB in a first type of slot and the number of REs in one PRB in a second type of slot, N _RE And

respectively representing the total number of REs in the first type of time slot and the total number of REs in the second type of time slot.

It should be noted that table 1 only shows several possible definitions of K, and in a specific implementation, the definitions of K may be other, which are not listed here.

By the mode for determining the information bit quantity, the calculation of the information bit quantity can be more accurate on the premise of utilizing the special time slot to carry out uplink transmission, and the accuracy of information transmission is improved.

In the above, the process of one-time transmission of the uplink transport block is introduced, and in a specific implementation, the uplink transport block may also be sent in a manner of repeated transmission.

In this way, if the first signaling does not indicate the number of times of retransmission, it may be considered that the uplink transport block does not support (or does not perform) retransmission.

If the uplink transmission block is repeatedly transmitted, the terminal device may determine the time domain resource of the next repeated transmission according to the repetition interval. The definition of the repetition interval may refer to three examples of the repetition interval described in the above step S201.

The repetition interval may be indicated by the first signaling, and the indication manner may specifically refer to the related description of the first signaling. Alternatively, the repetition interval may be pre-configured, for example, the starting time slot of each repeated transmission is at the same position of the uplink and downlink time slot matching period, and so on.

The starting position of the repeated transmission is explained below with different examples of repetition intervals. Repeating transmission traversing the uplink transmission block, and recording the repeating transmission as repetition # M, wherein M =0,1, …, M-1; it should be understood that repetition #0 represents the first transmission of the uplink transport block.

For example 1, the starting timeslot of each retransmission is at the same position in the uplink and downlink timeslot matching period. For example, assuming that the downlink timeslot configuration period is "DDDSUDDSUU", and the start timeslot of repetition #0 is the first special timeslot of one uplink and downlink timeslot configuration period, the start timeslot of repetition # m is the first special timeslot of another uplink and downlink timeslot configuration period, as shown in fig. 9.

In this manner, the starting position of each repetition can be determined by a preconfigured repetition interval (or a default repetition interval).

Example 2, in connection with example one of the repetition interval, the starting slot of repetition # m differs from the starting slot of repetition # m-1 by I. For example, it is assumed that the uplink and downlink timeslot configuration period is "DDDSUDDSUU" and 10 timeslots are allocated for the uplink transport block. The time slot allocated for repeating # m-1 is 10 time slots of a matching cycle of uplink and downlink time slots, the starting time slot is the first downlink time slot of the matching cycle of uplink and downlink time slots, and if the repetition interval I =10 time slots, the starting time slot of repeating # m is a time slot after 10 time slots, that is, the first downlink time slot of the matching cycle of next uplink and downlink time slots, as shown in fig. 10.

For example 3, in connection with example two of the repetition interval, the starting slot of repetition # m differs from the last slot (i.e., the last physical slot) allocated to repetition # m-1 by I. For example, it is assumed that the uplink and downlink timeslot allocation period is "DDDSUDDSUU" and 7 timeslots are allocated for the uplink transport block. The timeslot allocated for repetition # m-1 is the first 7 timeslots of an uplink and downlink timeslot matching period, the last timeslot allocated for repetition # m-1 is the fifth downlink timeslot of the uplink and downlink timeslot matching period, and if the repetition interval I =6 timeslots, the starting timeslot of repetition # m is the 1 st special timeslot of the next uplink and downlink timeslot matching period, as shown in fig. 11.

For example 4, in connection with example three of the repetition interval, the starting slot of repetition # m differs by I from the last slot actually used by repetition # m-1 (i.e., the last available slot). For example, it is assumed that the uplink and downlink timeslot matching period is "DDDSUDDSUU", and 10 timeslots are allocated for the uplink transport block. The time slot allocated for the repetition # m-1 is 10 time slots of an uplink and downlink time slot matching period, the last time slot actually used for the repetition # m-1 is the second uplink time slot of the uplink and downlink time slot matching period, and if the repetition interval I =4 time slots, the starting time slot of the repetition # m is the first special time slot of the next uplink and downlink time slot matching period, as shown in fig. 12.

Based on the above-mentioned determination of the starting time slot, the time domain resource in each repeated transmission may be determined according to the method described in S202.

By the above-mentioned manner of determining the starting position of the repeated transmission, the time domain resource allocation of each repeated transmission can be consistent, so that the prior art repetition type a (repetition type a) can be multiplexed. In addition, by the mode, the repetition interval can be indicated more flexibly, a longer repetition interval can be indicated, time diversity gain can be acquired, and uplink coverage performance can be improved.

For example, taking the method described in fig. 4 as an example, assuming that the uplink and downlink timeslot matching period "DDDSUDDSUU", N =10, the number of timeslots allocated for each retransmission is 10, as shown in fig. 13, the downlink timeslot is removed and a second uplink timeslot is preempted by other high-priority signals or channels, repeat #0 actually uses 4 timeslots, and repeat #1 actually uses 5 timeslots.

For another example, taking the method described in fig. 6 as an example, assuming that the uplink and downlink timeslot matching period "DDDSUDDSUU", M =4, the number of actually used timeslots for each retransmission is 4, as shown in fig. 14, the downlink timeslot is removed and the second uplink timeslot is preempted by other high-priority signals or channels, repeat #0 actually uses the first two special timeslots and the first and three uplink timeslots, and repeat #1 actually uses the third and fourth special timeslots and the fourth and five uplink timeslots.

It should be noted that the definition of the repetition interval and the method for determining the starting time slot of the repetition interval provided in the embodiment of the present application may be implemented independently of the method described in fig. 2. In addition, the method for determining the information bit amount corresponding to the uplink transport block according to the parameter K for scaling provided in the embodiment of the present application may also be implemented independently without depending on the method illustrated in fig. 2.

In addition, by the above method for determining the information bit quantity, the calculation of the information bit quantity can be more accurate on the premise of performing uplink transmission by using a special time slot, and the accuracy of information transmission is improved.

In addition, by the above-mentioned manner of determining the starting position of the repeated transmission, the time domain resource allocation of each repeated transmission can be consistent, so that the related art repetition type a (repetition type a) can be multiplexed. In addition, by the mode, the repetition interval can be indicated more flexibly, a longer repetition interval can be indicated, time diversity gain is acquired, and uplink coverage performance is improved.

Based on the same inventive concept as the method embodiment, the embodiment of the present application provides a communication apparatus, which may have a structure as shown in fig. 15 and includes a communication module 1501 and a processing module 1502.

In an implementation manner, the communication apparatus may be specifically used to implement the method performed by the terminal device in the embodiment of fig. 2, and the apparatus may be the terminal device itself, or may be a chip or a chip set in the terminal device or a part of the chip for performing the function of the related method.

Based on the above manner, when the communication module 1501 sends the uplink signal transmission block on the time domain resource, it may specifically be configured to: and transmitting the uplink signal on the time domain resource.

For example, the resource corresponding to the second time unit refers to a resource used for sending the uplink transport block in the resource corresponding to the second time unit, and the resource corresponding to the first time unit refers to a resource used for sending the uplink transport block in the resource corresponding to the first time unit.

Optionally, the processing module 1502 may further be configured to: repeatedly transmitting the uplink transport block through the communication module 1501 based on the repetition interval;

wherein the repetition interval is indicated by the first signaling, or the repetition interval is preconfigured; the repetition interval indicates a time interval between start time slots of two adjacent repeated transmissions; or, the repetition interval indicates a time interval between a last time slot of a plurality of time slots configured for a previous repeated transmission in two adjacent repeated transmissions and a starting time slot of a subsequent repeated transmission; or, the repetition interval indicates a time interval between a last time slot for uplink transmission in a previous repeated transmission and a starting time slot of a next repeated transmission in two adjacent repeated transmissions.

Illustratively, the unit of the time interval is a timeslot, or a third time unit, or a mini timeslot, or a subframe, or a half frame, or a frame, or an uplink and downlink timeslot matching period, or a millisecond, where the third time unit is one timeslot for uplink transmission or the third time unit is a plurality of consecutive timeslots for uplink transmission.

In an embodiment, the communication apparatus may be specifically used to implement the method performed by the network device in the embodiment of fig. 2, and the apparatus may be the network device itself, or may be a chip or a chip set in the network device, or a part of a chip in the chip for performing a function of the relevant method. The communication module 1501 is configured to send a first signaling, where the first signaling is used to indicate that an uplink transport block is sent on multiple timeslots, and the first signaling indicates a first symbol and a second symbol, where the first symbol includes at least one symbol, and the second symbol includes at least one symbol; a processing module 1502, configured to determine, based on the first signaling, a time domain resource for receiving an uplink transport block, where the time domain resource includes a time domain resource on a first time slot, a first symbol on the first time slot includes a downlink symbol, and a second symbol on the first time slot does not include the downlink symbol; the communication module 1501 is further configured to receive an uplink transport block on the time domain resource.
