Optionally, in the embodiment of the present application, the at least one first RV is all RVs in the mapping relationship; and the at least one first DMRS is all DMRSs in the mapping relationship.

That is, in the mapping relationship, all RVs have a one-to-one relationship with all DMRSs.

Thereby, the RV can be directly identified by the DMRS currently transmitted, and the RV blind detection can be avoided. In addition, when there are multiple RVs, multiple RVs can be used to obtain multiple RV combined gains.

Specifically, when performing transmission of the target data, the previous plurality of DMRSs may correspond to one RV, for example, RV0; the subsequent multiple DMRSs may correspond to another one or more RVs.

Therefore, RV0 is used in the previous transmissions to facilitate self-test. The use of other RVs in the next few transmissions is beneficial to obtain the RV combining gain. This design makes use of the law that the probability of the user is not detected decreases as the number of transmissions increases. The self-test and RV combining gains are balanced.

That is, at the same time as the DMRS of the current sub-transmission of the target data, the RV of the current sub-transmission of the target data may be further combined to determine the number of transmissions or the transmission starting point.

Thus, in addition to identifying the number of transmissions by the DMRS, it is also possible to further determine the number of transmissions based on the RV. The number of transmissions is determined jointly by DRMS and RV, and there is a correspondence between RV and DMRS. The number of blind detections of RV can be reduced under the determined total number of transmissions.

In order to understand the present application more clearly, the above method will be exemplified below. Before the description is given, the correspondence between data transmission and DMRS is first introduced.

The LTE system introduces a URLLC service that is characterized by ultra-high reliability (eg, 99.999%) transmission within an extreme delay (eg, 1 ms). In order to achieve this goal, multiple repeated transmission and semi-persistent transmission techniques have been proposed to solve the reliability and delay problems.

When the two technologies are combined, that is, the same data packet is repeatedly transmitted in a semi-continuous resource, both the reliability problem and the low delay problem can be solved. In addition, when the user can initiate uplink transmission according to his own needs, the base station side cannot guarantee that each transmission can detect and identify, so the base station may not be aware of the number of transmissions. When the number of transmissions is unknown, the signal may not be resolved, or the combination of multiple transmission packets may not be performed. This can be achieved in a number of ways. Among them, X1, X2, X3 and X4 in Fig. 5-7 represent DMRS, and the data transmission of the underlined DMRS is the first data transmission, that is, the transmission starting point of the data transmission in the case of multiple data transmission.

Mode A: The DMRS has a one-to-one correspondence with the number of transmissions. For example, as shown in FIG. 5, X1, X2, X3, and X4 are four types of DMRS transmissions, and the transmitted DMRS indicates the current transmission of the first transmission belonging to the data.

Mode B: Two DMRSs (X1, X2) are used for the first transmission and the subsequent transmission, respectively. As shown in Fig. 6, the starting position of the data, that is, the starting position of the first transmission, is determined by X1.

Mode C: The DMRS combination corresponds to the transmission starting point, and the starting position is determined by the DMRS combination, that is, the starting position of the first transmission, specifically, the combination of X1 and X1, the combination of X1 and X2, and the combination of X2 and X1. , and the combination of X2 and X2 represents four starting positions, for example, as shown in FIG. Wherein, the total number of data transmissions can be determined.

The embodiments of the present application will be described below in combination with various methods. It should be understood that the following methods can be used in combination. It should be understood that the contents of the following items are merely illustrative, and the embodiments of the present application should not be specifically limited.

An illustration of method 200.

Method 1: The RV corresponds to the DMRS one by one, for example, as shown in Table 1.

Table 1

DMRS	X1	X2	X3	X4
RV	0	1	2	3

Specifically, for the three DMRS mapping modes in FIG. 5-7, the corresponding RVs may be as shown in Table 2.

Table 2

Thus, the RV version can be directly identified by the DMRS, and RV blind detection can be avoided. Second, multiple RV versions can achieve multiple RV combined gains. In the embodiment of the present application, the RV blind detection may refer to acquiring data by using a possible RV.

Mode 2: RV and DMRS are one-to-many, for example, as shown in Table 3 and Table 5.

table 3

DMRS	X1	X2	X3	X4
RV	0	0	0	0

Specifically, based on Table 3, for the three DMRS mapping modes in FIG. 5-7, the corresponding RVs may be as shown in Table 4.

Table 4

DMRS

RV

Mode A	X1	X2	X3	X4	0	0	0	0
Mode B	X1	X2	X2	X2	0	0	0	0
Mode C	X1	X2	X1	X2	0	0	0	0

Thus, the RV is fixed, especially RV0, which facilitates self-detection of data if no previous transmission is detected.

table 5

DMRS	X1	X2	X3	X4
RV	0	0	1	1

Specifically, based on Table 5, for the three DMRS mapping modes in FIG. 5-7, the corresponding RVs may be as shown in Table 6.

Table 6

Therefore, RV0 is used in the previous transmissions to facilitate self-test. The use of other RVs in the next few transmissions is beneficial to obtain the RV combining gain. This design utilizes the law that the probability of the user is not detected decreases as the number of transmissions increases. The self-test and RV combining gains are balanced. Simultaneously bind to DMRS, reducing blind detection of RV

Mode 3: RV and DMRS are many-to-one, for example, as shown in Table 7.

Table 7

DMRS	X1	X2	X3	X4
RV	0,1	0,1	0,1	0,1

Specifically, based on Table 7, for the three DMRS mapping modes of FIG. 5-7, the corresponding RVs may be as shown in Table 8.

Table 8

Thus, in addition to identifying the number of transmissions by the DMRS, it is also possible to further determine the number of transmissions based on the RV. The number of transmissions is determined jointly by DRMS and RV, and there is a correspondence between RV and DMRS. The number of blind detections of RV can be reduced under the determined total number of transmissions. An illustration of method 300.

Method 1: The RV corresponds to the number of transmissions, for example, as shown in Table 9 below.

Table 9

Number of transmissions	A1	A2	A3	A4
RV	0	1	2	3

Thus, by blindly detecting the RV, the number of transmissions can be determined. Once the transmission secondary is determined, RV blind detection can be avoided.

Mode 2: The RV is one-to-one with the number of transmissions, for example, as shown in Tables 10 and 11 below.

Table 10

Number of transmissions	A1	A2	A3	A4
RV	0	1	1	1

Thus, by blindly detecting the RV, the position of the specific number of transmissions can be obtained and the RV blind detection range is reduced.

Table 11

Thus, by blindly detecting the RV and combining other information, the position of a specific number of transmissions can be obtained. The RV blind detection range is reduced.

Mode 3: The number of RVs and the number of transmissions are many, for example, as shown in Table 12 below.

Table 12

Wherein, in the case where the RV and the DMRS are many-to-one, the RV can be obtained by blind detection, and other information such as a user number can be obtained. For example, Table 13 and Table 14 may respectively correspond to the number of transmissions of two different user configurations and RV. The corresponding relationship between the RV and the DMRS may be configured for the network device. On the terminal device side, the correspondence between the RV and the number of transmissions corresponding to each user may be configured. Is a one-to-many relationship (for example, Table 13), or a one-to-one relationship (for example, Table 14).

Table 13

Number of transmissions	A1	A2	A3	A4
RV	0	1	0	1

Table 14

Number of transmissions	A1	A2	A3	A4
RV	0	0	1	1

An example of method 400:

The number of transmissions is determined by any one, two or three combinations of resource locations (time domain locations), DMRS, and RV versions. Wherein, in the case that the number of transmissions is not determined only according to the DMRS, the problem of insufficient DMRS resources can be solved.

Mode 1: The frequency domain location is combined with the DMRS, for example, as shown in Table 15 below.

Table 15

Number of transmissions	A1	A2	A3	A4
Frequency domain location	0	0	1	1
DMRS	0	1	0	1

Thus, by using the frequency domain position, both the frequency diversity gain and the indication transmission secondary transmission can be obtained.

Mode 2: RV is combined with DMRS, for example, as shown in Table 16 below.

Table 16

Thereby, the transmission secondary transmission can be identified under a limited number of RV blind detections.

Mode 3: The RV is combined with the frequency domain, for example, as shown in Table 17 below.

Table 17

Number of transmissions	A1	A2	A3	A4
RV	0	0	1	1
Frequency domain location	0	1	0	1

Thereby, the transmission secondary transmission can be identified under a limited number of RV blind detections. With the frequency domain position, both the frequency diversity gain and the indication transmission sub-transmission can be obtained.

Mode 4: The RV is combined with the frequency domain, for example, as shown in Table 18 below.

Table 18

Number of transmissions	A1	A2	A3	A4	A1	A2	A3	A4
RV	0	0	1	1	0	0	1	1
Frequency domain location	0	1	0	1	0	1	0	1
DMRS	0	0	0	0	0	0	0	0

Thus, under the limited number of RV blind detections, the transmission secondary transmission is identified. With the frequency domain position, both the frequency diversity gain and the indication transmission sub-transmission can be obtained. Reduce DMRS orthogonal resource overhead, increase user reuse rate, and support larger repetitions.

Optionally, when at least two factors of the frequency domain location, the RV, and the DMRS determine the number of transmissions, the at least two factors may collectively correspond to A1, A2, A3, and A4 in FIG. 5-7.

It should be understood that the above is merely an example, and the present application should not be specifically limited.

For example, RV takes a value of 0 or 1, and RV can take other values, such as 2, or 3. For example, RV can be RV0 and RV3 in the presence of two selectable values, that is, RV1 mentioned in the above example can be replaced with RV3.

For example, the number of transmissions A1, A2, A3, and A4 may be four times in total, or may be other times, and the value of the number of transmissions may be greater than or equal to zero.

For example, the available DMRS sequence may be other numbers, at least greater than or equal to zero.
