First, relevant terms in the present application are explained.

Waveform of first and uplink signals

The uplink signal has two transmission waveforms: cyclic Prefix Orthogonal Frequency Division Multiplexing (CP-OFDM) waveforms and Fourier Orthogonal Frequency Division Multiplexing (DFT-S-OFDM) waveforms. An uplink transmission waveform of the uplink signal is indicated by a system message, wherein when transform precoding disabled (transmission precoding/transform precoding is not enabled), it indicates that a CP-OFDM waveform is used; when transform precoding enabled, it means that a DFT-s-OFDM waveform is used.

Second, PUSCH Repetition type B

A Physical Uplink Shared Channel (PUSCH) repeat transmission scheme called PUSCH repeat type B (repeat type B) is introduced in the existing protocol. In this scheme, a single non-Fallback Downlink Control Information (DCI) (non-Fallback DCI, which may be DCI format 0_1 or DCI format 0_2) may schedule one to multiple temporally consecutive Nominal repetition PUSCHs determined by this row by indicating an index of a certain row in a time domain resource allocation table configured in a higher layer, where a first Nominal repetition PUSCH in the Nominal repetition PUSCHs is determined by a K2 parameter and a SLIV in this row, and the remaining Nominal repetition PUSCHs are arranged next to each other, i.e., time domain resource allocation of M × K consecutive symbols is determined accordingly (where M is the number of consecutive symbols occupied by each Nominal repetition PUSCH, and K is the number of temporally consecutive Nominal repetition DCI PUSCH). When a certain non-Fallback DCI format is configured to support PUSCH repetition type B, a column of number repetition parameters is added to the previous time domain resource allocation table in the time domain resource allocation table configured independently for the certain non-Fallback DCI format, and the number repetition parameters in each row in the resource allocation table can be configured independently to indicate the number of the corresponding passive repetitions PUSCH in the row.

The temporally continuous Nominal retransmission PUSCH scheduled by DCI is further segmented, and a series of Actual retransmission PUSCH transmissions are formed based on the original boundaries between the Nominal PUSCHs and the boundaries where the segmentation occurs newly, and are repeated transmissions for a single Transport Block (TB) or Hybrid Automatic Repeat reQuest (HARQ) process scheduled by DCI:

always segmented based on slot boundaries when a certain Nominal repetition PUSCH crosses a slot boundary;

the Nominal repetition PUSCH is segmented before and after the semi-static DL symbols configured at the high layer (the semi-static DL symbols in the range of M × K are not occupied by the PUSCH);

when a dynamic Slot Format Indicator (dynamic SFI) is configured, a Pattern for Invalid symbols may also be optionally configured for the non-Fallback DCI Format, and the Nominal reptitions PUSCH is indicated based on 1 bit in the DCI or always segmented (when the aforementioned 1 bit does not exist) before and after the Invalid symbols (Invalid symbols in the M K range are not occupied by PUSCH).

When the OFDM symbol length occupied by the actual retransmission is 1, the actual retransmission is ignored unless the time domain resource allocation length L in the configuration of the retransmission transmission is 1.

Third, PUSCH DMRS sequence generation

DMRS sequence of CP-OFDM waveform:

wherein (c) (i) is a pseudo-random sequence, and two m sequences are obtained through calculation:

c(n)＝(x ₁ (n+N _C )+x ₂ (n+N _C ))mod2

x ₁ (n+31)＝(x ₁ (n+3)+x ₁ (n))mod2

x ₂ (n+31)＝(x ₂ (n+3)+x ₂ (n+2)+x ₂ (n+1)+x ₂ (n))mod2

wherein N is _C 1600, sequence x ₁ (n) has a fixed initialization state x ₁ (0)＝1,x ₁ (n) 0,

n

1,2, 30, sequence x ₂ (n) initialization status by parameter

It is determined that,

it can be seen that: the value of c _ init is related to the slot number where the DMRS is located and the symbol number in the slot.

DMRS sequence of DFT-s-OFDM waveform:

wherein

According to the configuration:

wherein, if the higher layer parameter dmrs-uplinktransnforprcoding is configured, the PUSCH uses pi/2-BPSK modulation scheme, and the PUSCH is not msg3 PUSCH, and the transmission is not the transmission scheduled by DCI format 0_0 on common search space, the sequence thereof is generated by Low-sequence type 2, and the initial value thereof is given by the following formula:

it can be seen that the value of c _ init is related to the slot number where the DMRS is located and the symbol number in the slot.

If not, then,

the sequence is generated by Low-PAPR sequence type 1, namely:

wherein, when the sequence length is more than or equal to 36,

when the length of the sequence is equal to 30,

when the sequence length is equal to 6,12,18,24,

further, in the above sequence, the sequence group identification

And the sequence group jump parameter f _gh And determination of the value of sequence number v:

if both group hosting and sequence hosting are disabled, then f _gh ＝0，v＝0；

If group hosting enabled and sequence hosting disabled, then:

v＝0

if group hosting disabled and sequence hosting enabled, then:

f _gh ＝0

in the above process, the DMRS sequence is generated according to the slot number of the DMRS and the symbol number in the slot.

Only when transform precoding enabled and time domain resource allocation of PUSCH transmission is less than or equal to 2 OFDM symbols, REs which are not used by the DMRS on the time domain OFDM symbol where the DMRS is located can be used for transmitting data; otherwise, the REs which are not used by the DMRS on the time domain OFDM symbol where the DMRS is located cannot be used for transmitting data.

Fourthly, UE PUSCH preparation time

If the first uplink symbol in the PUSCH allocation (including DMRS) for transmitting one TB is not earlier than symbol L2 after considering the influence of ta (timing advance), the UE transmits the PUSCH carrying the TB;

otherwise, the UE may ignore the DCI scheduling the PUSCH.

Wherein, the PUSCH allocation and the first uplink symbol thereof are mainly indicated by a Time Domain Resource Assignment (TDRA) field in DCI that schedules the PUSCH;

the symbol L2 is defined as: after receiving the latter symbol of PDCCH (carrying DCI scheduling the PUSCH), T is passed _proc,2 The next uplink symbol after time (containing the CP of the symbol itself).

Further, the PUSCH preparation time is:

T _pr o _c,2 ＝max((N ₂ +d _2,1 +d ₂ )(2048+144)·κ2 ^-μ ·T _C +T _ext +T _switch ,d _2,2 )

if the first symbol of PUSCH allocation only contains DMRS, d in the above formula _2,1 Is 0; otherwise, d _2,1 Is 1.

The uplink transmission method provided in the embodiments of the present application is described in detail below with reference to the accompanying drawings through some embodiments and application scenarios thereof.

As shown in fig. 2, the method of the uplink transmission method in the embodiment of the present application includes:

step 202, the terminal determines a transmission mode of the first uplink transmission on the target Orthogonal Frequency Division Multiplexing (OFDM) symbol according to the first information;

step 204, the terminal executes first uplink transmission based on the transmission mode;

the time domain resources allocated for the second uplink transmission are L OFDM symbols, the second uplink transmission includes the first uplink transmission, and the time domain resources used for actual transmission in the first uplink transmission are L1 OFDM symbols in L; l is greater than or equal to L1, and L is a positive integer greater than 1.

Through the above steps 202 and 204, a transmission manner of the first uplink transmission on L1 OFDM symbols of the time domain resource for actual transmission may be determined according to the first information, and the time domain resource for actual transmission may be a resource divided from nominal retransmission (nominal retransmission) into actual retransmission (actual retransmission) in a specific application scenario. That is to say, the present application may determine a transmission mode on actual repeated transmission, for example, DMRS or data transmission is performed, and some additional resources are provided for adjacent repeated transmission or uplink transmission, so as to avoid a problem of resource waste caused by directly canceling actual repeated transmission or transmission that does not satisfy transmission resource restriction in the prior art.

In an optional implementation manner of the embodiment of the present application, before the terminal involved in step 202 determines the transmission mode of the first uplink transmission according to the first information, the method of the embodiment of the present application may further include:

200, the terminal acquires the first information in at least one of the following modes:

1) pre-defining rules;

2) an uplink grant (UL grant) corresponding to first uplink transmission;

wherein, for a Dynamic Grant (DG) PUSCH, the UL Grant is carried by DCI scheduling the PUSCH; for a type 1CG (Configured Grant) PUSCH, the UL Grant is a Configured Grant; for type 2CG PUSCH, the UL grant is configured grant, but DCI is required for activation/deactivation. If the first uplink transmission is a retransmission transmission, the UL grant is the grant of the retransmission transmission

3) A UL grant corresponding to the second uplink transmission; the second uplink transmission is associated with the first uplink transmission;

the association means that some transmission contents are shared between the first uplink transmission and the second uplink transmission, for example, the first uplink transmission and the second uplink transmission share the DMRS, and joint channel estimation can be performed; or the first uplink transmission and the second uplink transmission belong to the same DMRS bundling.

4) Radio Resource Control (RRC) configuration;

5) a Medium Access Control-Control Element (MAC CE).

In an optional implementation manner of the embodiment of the present application, the first uplink transmission involved in the embodiment of the present application includes at least one of the following:

1) a physical uplink shared channel repeat transmission type A (PUSCH retransmission type A);

2) a physical uplink shared channel repeat transmission type B (PUSCH retransmission type B);

3) transmission of a physical uplink shared channel across multiple slots (PUSCH TBoMS);

It should be noted that the physical uplink shared channel repeat transmission type a and the physical uplink shared channel repeat transmission type B included in the first uplink transmission indicate that the first uplink transmission includes transmission corresponding to the physical uplink shared channel repeat transmission type a and transmission corresponding to the physical uplink shared channel repeat transmission type B.

Based on the type of the first uplink transmission, in an optional implementation manner of this embodiment, in a case that the first uplink transmission includes at least one of PUSCH repetition type a and PUCCH, L-N > ═ L1; wherein, N is obtained through high-level parameter configuration or through a predefined mode.

Where, configured by the higher layer parameter, N may be 1,2, … M, where M is a positive integer. N obtained by a predefined manner may refer to N obtained by: n ═ floor (L/2) or N ═ ceil (L/2). Wherein, floor means rounding down, ceil means rounding up.

It should be noted that, in the existing protocol, for PUSCH repetition type a and PUCCH, as long as L1< L, the transmission resource is unavailable. In order to make the transmission resources available in this case, the condition is set to L-N > -L1, where N is obtained by higher layer parameter configuration on the network side or by a predefined manner. Therefore, in the embodiment of the present application, even when L1 is smaller than L, an unavailable resource can be changed into an available resource, so as to improve the resource utilization rate.

Based on the type of the first uplink transmission, in an optional implementation manner of the embodiment of the present application, when the first uplink transmission is a PUSCH repetition type B, L1 is 1; wherein, L1 is the number of OFDM symbols occupied by PUSCH transmission corresponding to actual repetition transmission.

In an optional implementation manner of the embodiment of the present application, the first information in the embodiment of the present application is used to indicate at least one of the following:

1) enabling a first uplink transmission;

2) the transmission mode is that only a demodulation reference signal DMRS is transmitted;

3) the transmission mode is to transmit data only;

4) the transmission mode is that only control information is transmitted;

5) the transmission mode is that data and DMRS are transmitted simultaneously;

The transmission schemes 1) to 6) indicated by the first information are not limited to L1. In yet another optional implementation manner of the embodiment of the present application, the first information in the embodiment of the present application may be used to indicate at least one of the following:

1) in the case where L1 equals 1, the transmission mode includes one of: only DMRS, only data, only control information are transmitted;

3) in case L1 is equal to 1 and the first uplink transmission is physical uplink control channel format 2PUCCH format2, the transmission scheme includes one of: transmitting only the DMRS, only the control information, and simultaneously transmitting the control information and the DMRS;

4) in the case where L1 is greater than 1, the transmission mode includes one of: transmitting only data, simultaneously transmitting the data and the DMRS, and simultaneously transmitting control information and the DMRS.

As can be seen, in the above-mentioned modes 1) to 4) indicated by the first information, when the first information indicates a different value of L1, the corresponding transmission mode is used.

In an optional implementation manner of the embodiment of the present application, when the transmission scheme is to transmit only the DMRS, the first uplink transmission has at least one of the following features:

and (2) characteristic 17: the RV used for data transmission in the first uplink transmission meets the first RV;

feature 18: with frequency hopping enabled, the first uplink transmission may be treated as an independent hop.

Wherein the first RV comprises at least one of:

1) an RV determined by a first preconfigured RV cycle rule;

wherein the first preconfigured RV cycle rule is for RV used for repeption type B to determine current actual repeption based on actual repeption; for the repetition type a or other PUSCHs, the RV used for the current repetition is determined based on the number of the current repetition.

3) using the same RV as used for a first actual repeated transmission, wherein the first actual repeated transmission and a current repeated transmission belong to the same nominal repeated transmission, and the first actual repeated transmission is adjacent to the current repeated transmission;

4) an RV determined by a second preconfigured RV cycle rule, wherein the second preconfigured RV cycle rule is used for determining the RV used by the current nominal repeat transmission as a whole.

In an optional implementation manner of the embodiment of the present application, the method of the embodiment of the present application may further include:

in step 206, in case the first uplink transmission is before the first allocated OFDM symbol of the second uplink transmission, the preparation time T _ proc _ new is determined by one of:

the value of T _ proc _ new is equal to the value of T _ proc, and the first sending OFDM symbol defined by T _ proc _ new is the first OFDM symbol of the first uplink transmission;

the value of T _ proc _ new is the result of the sum of T _ proc and the target time interval, which is the time interval between the first OFDM symbol of the first uplink transmission and the first allocated OFDM symbol of the second uplink transmission.

It should be noted that, for adjacent uplink transmission (preceding adjacent uplink transmission or following adjacent uplink transmission), the second uplink transmission may be PUSCH transmission or PUCCH transmission.

The present application is illustrated below with reference to specific embodiments of examples of the present application;

alternative embodiment 1:

as shown in fig. 3, if PUSCH retransmission type B transmission is configured, where S is 8 and L is 5 in TDRA, the slot boundary between slot #1 and slot #2 divides nominal retransmission #2 into actual retransmission #2 and actual retransmission #3, where actual retransmission #2 actually occupies 1 OFDM symbol, and actual retransmission #2 is determined by the existing protocol.

But the actual repetition transmission DMRS in this case is specified by a predefined rule (first information) in the embodiment of the present application;

the following manners all assume that the mapping type of the DMRSs is type 1 DMRSs.

Mode 1-1: at this time, actual repetition #2 transmits the DMRS, the used slot number is 1, and the OFDM symbol number is 13 to generate a corresponding DMRS sequence for transmission; in fact, the DMRS may be used or shared by actual repetition #1 and may also be used or shared by actual repetition # 3. From the receiving end, the DMRS sequence transmitted by actual repetition #2 is known; the DMRS configuration information related to actual repetition #2 is the same as the DMRS configuration information related to actual repetition #1 and actual repetition # 3.

a) When the DMRS transmitted by the actual repetition #2 is used by both the actual repetition #1 and the actual repetition #3, the DMRS thereof is reused, as shown in fig. 4.

b) When the DMRS transmitted by the actual repetition #2 is used by both the actual repetition #1 and the actual repetition #3, the DMRS distinguishes the DMRS used by the actual repetition #1 and the DMRS used by the actual repetition #3 by introducing an RE offset, as shown in fig. 5.

Mode 1 to 2: when inter-slot hopping is enabled, the actual repetition #2 transmission may not be made as a single hop, and may belong to the same hop as the actual repetition #1, as shown in fig. 6.

When inter-repetition hopping is enabled, the actual repetition #2 transmission may not be made as a single hop, and may belong to the same hop as the actual repetition #3 belonging to the same nominal repetition, as shown in fig. 7.

When actual repetition in this case is instructed by the grant information (first information) of the repetition, DMRS and data are transmitted at the same time.

Modes 1 to 3: actual repetition #2 may be used by actual repetition #1 to simultaneously transmit DMRS and data, as shown in fig. 8.

At this time, the DMRS transmitted by actual repetition #2 may use the same DMRS and its configuration in actual repetition # 1; or the DMRS sequence transmitted by the actual repetition #2 determines a corresponding DMRS sequence according to the slot number of the actual repetition #2 and the OFDM symbol number, and other related DMRS configurations are related to the DMRS in the actual repetition # 1.

The residual REs after the actual repetition #2 is mapped with the DMRS can be used for transmitting data in the actual repetition #1, the residual REs are used as extra transmission resources of the actual repetition #1, modulation symbols which are originally mapped to the actual repetition #1 can be further mapped to more available resources through rate matching, and therefore the transmission code rate is reduced.

Alternative embodiment 2

As shown in fig. 9, assuming that PUSCH repetition type B transmission is configured, where S is 9 and L is 2 in TDRA, the slot boundary between slot #1 and slot #2 divides the nominal repetition #3 into actual repetition #3 and actual repetition #4, and both occupy 1 OFDM symbol, and both actual repetition #3 and actual repetition #4 are determined by means of the existing protocol.

Mode 2-1: if it is determined from the first information that the actual repetition in this case is all used for transmitting DMRS, then the actual repetition #3 may be used or shared by the actual repetition #2, and the actual repetition #4 may be used or shared by the actual repetition #5, and further, the location of DMRS in the actual repetition #2 or the actual repetition #5 may be optimized, as shown in fig. 10.

At this time, the DMRS transmitted by the actual repetition #3 is the DMRS before optimization in the actual repetition #2, and only the position of the DMRS is optimized; or the DMRS sequence transmitted by the actual repetition #3 determines a corresponding DMRS sequence according to the slot number of the actual repetition #3 and the OFDM symbol number, and other related DMRS are configured with the DMRS before optimization in the actual repetition # 2.

The DMRS transmitted by the actual repetition #4 is the DMRS before optimization in the actual repetition #5, and only the position of the DMRS is optimized; or the DMRS sequence transmitted by the actual repetition #4 determines a corresponding DMRS sequence according to the slot number of the actual repetition #4 and the OFDM symbol number, and the other related DMRS configurations are the same as the DMRS before optimization in the actual repetition # 5.

Mode 2-2: if it is determined that the actual repetition part in this case is used for transmitting the PUSCH data and the actual repetition part is used for transmitting the DMRS according to the first information, that is, the actual repetition part is determined to be used for transmitting the PUSCH data and the actual repetition part is determined to be used for transmitting the DMRS: actual repetition #3 may be used as an additional transmission resource for actual repetition #2, and actual repetition #4 may be used or shared by actual repetition #5, as shown in fig. 11.

At this time, actual repetition #3 is used as an extra transmission resource of actual repetition #2, and the modulation symbols originally mapped to the actual repetition #2 can be further mapped to more available resources through rate matching, so that the transmission code rate is reduced.

Mode 2 to 3: if it is determined from the first information that the actual repetition in this case is used for transmitting all PUSCH data, the actual repetition #3 may be used as an additional transmission resource for the actual repetition #2, and the actual repetition #4 may be used as an additional transmission resource for the actual repetition #5, as shown in fig. 12.

At this time, the actual repetition #3 is used as an extra transmission resource of the actual repetition #2, and the modulation symbol originally mapped to the actual repetition #2 can be further mapped to more available resources through rate matching, so that the transmission code rate is reduced.

actual repetition #4 is used as an extra transmission resource of actual repetition #5, and the modulation symbols originally mapped to the actual repetition #5 can be further mapped to more available resources through rate matching, so that the transmission code rate is reduced.

As in the above-described modes 2-1, 2-2, 2-3, etc., if both actual repetition #3 and actual repetition #4 transmissions cannot be made as a single hop when inter-slot hopping is enabled, the actual repetition #3 may belong to the same hop as the actual repetition #2 belonging to the same slot, and the actual repetition #4 may belong to the same hop as the actual repetition #5 belonging to the same slot.

If inter-repetition frequency hopping is enabled, the actual repetition #3 and the actual repetition #4 cannot be transmitted as a single hop, and the actual repetition #3 and the actual repetition #2 are related to each other in transmission and can belong to the same hop; actual repetition #4 may belong to the same hop as it relates to the transmission of actual repetition # 5.

Alternative embodiment 3

As shown in fig. 13, assuming that PUSCH retransmission type B transmission is configured, where S is 5 and L is 3 in TDRA, the invalid symbol in slot #1 divides the nominal retransmission #3 into actual retransmission #3 and actual retransmission #4, and both occupy 1 OFDM symbol, and both actual retransmission #3 and actual retransmission #4 are updated according to the existing protocol.

If the actual repetition #3 and the actual repetition #4 are determined to be transmitted in this case based on the first information, the method is similar to the method 2-1, the method 2-2, and the method 2-3 in the optional embodiment 2.

If both the actual repetition #3 and the actual repetition #4 can not be taken as a single hop when inter-slot frequency hopping is enabled, the actual repetition #3 can belong to the same hop as the actual repetition #2 belonging to the same slot, and the actual repetition #4 and the actual repetition #5 do not belong to the same slot, and the transmission of the actual repetition #4 is not expected to be configured at this time, and is related to the transmission of the actual repetition #5 (for example, DMRS is used or used as available transmission resource of the actual repetition # 5), or the transmission according to the existing protocol, the actual repetition #4 is not expected to be configured; or to avoid this situation, it is not desirable to enable inter-slot hopping.

Alternative embodiment 4

As shown in fig. 14, assuming that PUSCH repetition type B transmission is configured, where S is 6 and L is 4 in TDRA, the invalid symbol in slot #1 divides the nominal repetition #2 into actual repetition #2 and actual repetition #3, and the actual repetition #3 occupies 1 OFDM symbol, and according to the existing protocol, the actual repetition #3 is always updated.

If the actual retransmission #3 transmission in this case is determined based on the first information, the difference is that, in the case of embodiment 1:

1) configuring transmission of actual repetition #3 in relation to transmission of actual repetition #4 (e.g., using DMRS or as available transmission resources for actual repetition # 5) when inter-slot hopping is not desired to be enabled; or when it is not desired to configure the transmission of actual repetition #3 in relation to the transmission of actual repetition #4, inter-slot hopping is not enabled.

2) The situation where the actual retransmission #3 transmission is related to the actual retransmission #2 transmission may be limited, such that when an invalid symbol is used for the DL, there is an undesirable association between the actual retransmission #3 and the actual retransmission #2 transmission.

Alternative embodiment 5

As shown in fig. 15, assuming that PUSCH retransmission type B transmission is configured, where S is 7 and L is 4 in TDRA, the invalid symbol in slot #1 and the slot boundary between slot #1 and slot #2 divide nominal retransmission #2 into actual retransmission #2, actual retransmission #3, and actual retransmission #4, which all occupy 1 OFDM symbol, and according to the existing protocol, actual retransmission #2, actual retransmission #3, and actual retransmission #4 are all updated.

If the actual repetition #2 transmission and the actual repetition #1 transmission are specified based on the first information, the operation is basically similar to the operation of embodiment 2, in which the actual repetition #2 transmission and the actual repetition #3 transmission are performed.

If the actual repetition #4 transmission and the actual repetition #5 transmission are determined based on the first information, the same situation as the actual repetition #4 transmission and the actual repetition #5 transmission in embodiment 2 is established;

if it is determined from the first information that actual repetition #3 transmission and actual repetition #4 transmission are simultaneously associated with actual repetition #5 transmission, the following scenario applies:

mode 5-1: as shown in fig. 16, actual repetition #3 and actual repetition #4 are used as extra transmission resources of actual repetition #5, and modulation symbols originally mapped to actual repetition #5 can be further mapped to more available resources by rate matching, thereby reducing the transmission code rate.

Mode 5-2: as shown in fig. 17, the DMRS sequence transmitted by actual repetition #3 determines a corresponding DMRS sequence according to the slot number where the actual repetition #3 is located and the OFDM symbol number, and other related DMRS configurations are related to the DMRS in actual repetition # 5;

or the DMRS sequence transmitted by the actual repetition #3 determines a corresponding DMRS sequence according to the slot number and the OFDM symbol number of the DMRS in the actual repetition #5, and the other related DMRS configurations are the same as the DMRS related configurations in the actual repetition # 5.

actual repetition #4 is used as an extra transmission resource of the actual repetition #5, and the modulation symbol originally mapped to the actual repetition #5 can be further mapped to more available resources through rate matching, so that the transmission code rate is reduced.

Further, DMRS positions may be optimized for DMRS transmitted by actual repetition #3 and DMRS transmitted by actual repetition #5, as shown in fig. 18.

At this time, the DMRS sequence transmitted by the actual repetition #5 determines a corresponding DMRS sequence according to the current slot number and the OFDM symbol number where the optimized DMRS is located, and the configuration of other related DMRS is kept unchanged.

Alternative embodiment 6

As shown in fig. 19, assuming that PUSCH1 is configured for PUSCH retransmission type B transmission, where S is 5 and L is 5 in TDRA, slot boundary of slot #1 and slot #2 divides nominal retransmission #2 into actual retransmission #2 and actual retransmission #3, and actual retransmission #3 occupies 1 OFDM symbol, and according to the existing protocol, both actual retransmission #3 are assigned. And actual repetition #3 is a scheduled transmission of PUSCH 2.

If the scheduling grant of the PUSCH2 includes the first information and it is determined that the actual repetition #3 can be used for transmission with the PUSCH, the actual repetition #3 may be used as an additional transmission resource of the PUSCH2 to transmit the corresponding DMRS or Data;

it can be seen that in this situation described above, the preparation time for PUSCH2 needs to be redefined (fig. 21) or a new preparation time is used (fig. 22), where fig. 20 is the preparation time T _ proc for PUSCH2 of the existing protocol; fig. 21 is a diagram illustrating redefinition of the preparation time T _ proc _ new1 of PUSCH2 in the above situation, where the value is equal to T _ proc, but the first symbol of PUSCH2 is defined as the first symbol of actual repetition # 3; fig. 22 shows that the PUSCH2 uses a new preparation time T _ proc _ new2, which is equal to T _ proc + delta, which is the time (including its CP) corresponding to the actual repetition #3 occupying the OFDM symbol.

As can be seen from the above optional embodiments, in the present application, an orphan symbol(s) may be used to perform uplink DMRS or data or control information transmission, so as to provide additional DMRS or additional available transmission resources for adjacent uplink transmission, thereby improving demodulation reliability and coverage capability.

It should be noted that, in the uplink transmission method provided in the embodiment of the present application, the execution main body may be an uplink transmission device, or a control module in the uplink transmission device for executing the uplink transmission method.

By the apparatus of the embodiment of the present application, a transmission mode of a first uplink transmission on L1 OFDM symbols of a time domain resource for actual transmission may be determined according to first information, and the time domain resource for actual transmission may be a resource divided into actual repeat transmission (actual repeat) from nominal repeat transmission (nominal repeat) in a specific application scenario. That is to say, the transmission mode on actual repeated transmission can be determined through the method and the device, for example, DMRS or data transmission is performed, and some additional resources are provided for adjacent repeated transmission or uplink transmission, so that the problem of resource waste caused by directly canceling actual repeated transmission or transmission not meeting transmission resource limitation in the prior art is solved.

In the existing protocol, as long as L1< L is applied to PUSCH repetition type a and PUCCH, the transmission resource is unavailable. In order to make the transmission resource available in this case, L-N > is set to L1, where N is configured by a higher layer parameter on the network side. Therefore, by the method in the embodiment of the present application, even when L1 is smaller than L, an unavailable resource can be changed into an available resource, so as to improve the resource utilization rate.
