Description

Transmission method of uplink control signaling, terminal equipment and base station

Technical Field

The present application relates to the field of communications technologies, and in particular, to a transmission method of an uplink control signaling, a terminal device, and a base station.

Background

The fifth generation (5G) communication technology proposes a new communication protocol 5G and a New Radio (NR) communication protocol. In the discussion process of 5G NR, the number of symbols occupied by uplink control signaling can be changed, the minimum number of occupied time domain symbols is 4, the longest number in a time slot can reach 14, and the total number of occupied symbols is uncertain when multiple time slots are occupied.

In Long Term Evolution (LTE), a subframe of 1ms is divided into two slots in the time domain, each slot occupies 0.5ms, and when a PUCCH is transmitted in each slot, the two sides of the whole frequency band are occupied, so as to provide the effect of diversity gain, that is, in LTE, the transmission PUCCH occupies the whole subframe. As can be seen from the above, the mode for transmitting PUCCH in LTE does not support uplink control signaling with flexible symbol number proposed by 5G, and there is no transmission mode capable of supporting uplink control signaling with flexible symbol number in the prior art.

For the long duration uplink control signaling, taking a long physical uplink control channel (long PUCCH) as an example, the following three cases exist in the structure of transmission in a slot, as shown in fig. 2. In fig. 2(a), the long-duration physical uplink control channel occupies all symbols on a slot, and the number of symbols in one slot may be 7 or 14; in fig. 2(b), the long-duration physical uplink control channel occupies all symbols after a Guard Period (GP) symbol in one slot, and occupies most time domain symbols in one slot; in fig. 2(c), the long-duration physical uplink control channel is located between the GP and the symbols occupied by the short-duration physical uplink control channel.

Fig. 3 is a diagram illustrating transmission of a physical uplink control channel in LTE. A subframe of 1ms is divided into two slots in the time domain, each slot occupies 0.5ms, and when PUCCH is transmitted in each slot, both sides of the entire system band are occupied, so as to provide an effect of diversity gain, that is, the transmission PUCCH occupies the entire subframe. The 1ms subframe includes 14 or 13 symbols, the first 7 symbols occupying one side of the system band for transmission, and the last 7 or 6 symbols occupying the other side of the system band for transmission. Since the number of symbols occupied by the long-duration PUCCH is more flexible, the related art has several problems,

the first problem is that: the mode of transmitting PUCCH in LTE does not support long-time uplink control signaling with flexible symbol number.

The second problem is that: another problem caused by long-time uplink control signaling with flexible symbol number is the capacity problem of different time slots. In the existing LTE, the length of the short-duration uplink control signaling is only 14 symbols, and only 13 symbols are used under special conditions, which does not involve the problem that the capacity of each time slot is different when the length of each time slot is different. In the 5G NR system, one timeslot may have 14 symbols to transmit long-duration uplink control signaling, and another timeslot after a period of time interval may have only 4 symbols to transmit long-duration uplink control signaling, and how to instruct the two timeslots to carry the same uplink control signaling or the same uplink control signaling is a problem to be involved in the scheme of the present invention.

The third problem is that: within a timeslot, there may be two long-duration uplink control signaling carrying the same uplink control information, and this possible implementation is not referred to in the prior art. In order to enhance the transmission reliability, a terminal device may transmit the same uplink control information using two beams, where each uplink control signaling is transmitted by only one beam, that is, two uplink control signaling in one timeslot are respectively carried by one beam with the same uplink control information. In this case, the problem of capacity matching between two uplink control signaling is also required.

Based on this, the embodiment of the present application provides a transmission scheme for an uplink control signaling, which determines a position of a DMRS in the uplink control signaling for uplink control signaling occupying different symbol numbers.

Referring to fig. 4, a flowchart of a method for transmitting a long-duration uplink control signaling provided in the embodiment of the present application is shown, where the method is used to solve a first existing problem, and the method includes:

s401, the base station sends configuration information to the terminal equipment.

The configuration information is used to instruct the terminal device to transmit a long-duration uplink control signaling on a first frequency hopping part and a second frequency hopping part, frequency domain resources occupied by the first frequency hopping part and the second frequency hopping part are different, the first frequency hopping part and the second frequency hopping part are located in at least one time slot in a time domain, at least one symbol in the first frequency hopping part is used to transmit a reference signal DMRS, and at least one symbol in the second frequency hopping part is used to transmit the DMRS.

S402, the terminal equipment acquires configuration information. Specifically, the terminal device receives configuration information sent by the base station.

S403, the terminal device transmits a long-duration uplink control signaling on a first frequency hopping part and a second frequency hopping part based on the configuration information, the frequency domain resources occupied by the first frequency hopping part and the second frequency hopping part are different, the first frequency hopping part and the second frequency hopping part are located in at least one time slot in a time domain, at least one symbol in the first frequency hopping part is used for transmitting the DMRS, and at least one symbol in the second frequency hopping part is used for transmitting the DMRS.

S404, the base station receives the long-time uplink control signaling sent by the terminal equipment on the first frequency hopping part and the second frequency hopping part.

The first frequency hopping part and the second frequency hopping part are located in at least one time slot in a time domain, and specifically, the first frequency hopping part and the second frequency hopping part as a whole are located in at least one time slot in the time domain.

Specifically, after receiving symbols for transmitting the DMRS, the base station measures channel information on symbols corresponding to the UCI, and then divides signals received by the symbols corresponding to the UCI by the measured corresponding channel information and decodes the signals, thereby obtaining control information.

Optionally, the terminal device transmits the uplink control signaling on the first frequency hopping part and the second frequency hopping part based on the configuration information, which may be specifically implemented by the following manner:

the terminal equipment transmits long-term and long-term uplink control signaling in the first frequency hopping part and the second frequency hopping part respectively based on the configuration information; alternatively, the first and second electrodes may be,

and the terminal equipment transmits the long-time uplink control signaling in a joint coding mode in the first frequency hopping part and the second frequency hopping part based on the configuration information.

Optionally, a plurality of frequency hopping parts may be occupied by transmitting a complete long-term uplink control signaling, and in this embodiment, two frequency hopping parts are occupied as an example. The first frequency hopping part and the second frequency hopping part as a whole may be located within one time slot, or may be located within two time slots or more than two time slots.

In the embodiment of the present application, the frequency hopping transmission of the long-term uplink control signaling can be divided into three cases, the first case: the first and second frequency hopping parts may have 1 symbol for transmitting the DMRS; in the second case: the first and second frequency hopping parts may have two symbols for transmitting the DMRS. In the third case: the number of symbols used by the first and second hopping parts to transmit the DMRS is different, i.e., the first hopping part has one symbol to transmit the DMRS and the second hopping part has two symbols to transmit the DMRS, or the first hopping part has two symbols to transmit the DMRS and the second hopping part has one symbol to transmit the DMRS.

In addition, it should be noted that, among the plurality of symbols in each frequency hopping part, other symbols than the symbol used for transmitting the DMRS are used for transmitting Uplink Control Information (UCI).

The following specifically describes the three cases mentioned above.

The first case is explained in detail by the following first embodiment.

The first embodiment is as follows:

a case where the first and second hopping parts each have 1 symbol for transmitting the DMRS is specifically described. Each frequency hopping part only contains 1 DMRS symbol, and in this case, the position of the DMRS should be located as far as possible in the middle of each frequency hopping part.

For example, the first hop portion includes X symbols and the second hop portion includes Y symbols.

When X is an odd number, (X +1)/2 symbols in the first hopping part are used to transmit the DMRS;

when X is an even number, the X/2 th symbol in the first frequency hopping part is used to transmit the DMRS, or the X/2+1 th symbol in the first frequency hopping part is used to transmit the DMRS.

Likewise, when Y is an odd number, (Y +1)/2 symbols in the second hopping part are used to transmit the DMRS;

when Y is an even number, the Y/2 th symbol in the second frequency hopping part is used to transmit the DMRS, or the Y/2+1 th symbol in the second frequency hopping part is used to transmit the DMRS.

For example, as shown in fig. 5A and fig. 5B, an example is given in which DMRS is transmitted in a certain odd number of symbols included in the entire long-duration control signaling. In fig. 5A, the first hopping part contains 5 symbols, the DMRS is located in the third symbol of the first hopping part, the second hopping part contains 4 symbols, and the DMRS is located in the second symbol of the second hopping part; in fig. 5B, the first frequency hopping part contains 5 symbols, the DMRS is located at the third symbol in the first frequency hopping part, the second frequency hopping part contains 4 symbols, and the DMRS is located at the third symbol in the second frequency hopping part.

Further, if the time domain position of the first frequency hopping part is earlier than that of the second frequency hopping part, in order to maintain the DMRS in the first frequency hopping part to be at a symmetrical position with the DMRS in the second frequency hopping part throughout the long-term uplink control signaling, the DMRS on the first frequency hopping part may be at a position of the second frequency hopping part

A symbol; on the second hopping part, the location of the DMRS on the second hopping part may be the second

A symbol.

The second case is specifically described by the following second to sixth embodiments, and specifically described by the following cases where the first and second frequency hopping parts each have 2 symbols for transmitting DMRSs.

In the embodiment of the present application, the following three ways are adopted to determine the positions of two symbols included in each frequency hopping part and used for transmitting the DMRS. In a first manner, two suitable symbols are selected from all the odd-numbered or even-numbered symbol ranges in each frequency hopping part for transmitting the DMRS, which is specifically described in the following second to fourth embodiments; in a second mode, two symbols in a middle position are adopted in each frequency hopping part for transmitting the DMRS, which is specifically described in the following embodiment five; in a third embodiment, two symbols symmetrically located in each hopping part are used for transmitting DMRS, which is specifically described in the following sixth embodiment.

Example two

The DMRS is positioned in some odd-numbered symbols in the symbols occupied by each frequency hopping part or the whole long and long uplink control signaling, wherein the odd-numbered symbols refer to 2N-1 symbol bits in all the symbols occupied by each frequency hopping part or the whole uplink control signaling, and N is 1 and 2 … …; or, the DMRS is located in some even-numbered symbols in the symbols occupied by each frequency hopping part or the entire long-duration uplink control signaling, where the even-numbered symbols refer to 2 nth symbol bits in all the symbols occupied by each frequency hopping part or the entire uplink control signaling, and N is 1 or 2 … …. In addition, it should be noted that, according to the symbols occupied by the entire long-term uplink control signaling, if the entire long-term uplink control signaling includes M frequency hopping parts, and each frequency hopping part has 2 symbols for transmitting the DMRS, then 2M symbols are used for transmitting the DMRS in the symbols occupied by the entire long-term uplink control signaling.

For example, when the first frequency hopping part comprises X symbols and the DMRS is located in the first frequency hopping part at two of odd-numbered symbols among the symbols occupied by the first frequency hopping part, when the DMRS is located in the first frequency hopping part

Is an odd number of the components,

Similarly, the position of the DMRS in the second frequency hopping part may be determined according to the DMRS in the first frequency hopping part, which is not described herein again.

Taking fig. 6A as an example, when the number of symbols occupied by the long-term uplink control signaling is 13 symbols, two frequency hopping portions occupied by the long-term uplink control signaling each have two symbols for transmitting the DMRS. The first hopping part occupies 7 symbols and the second hopping part occupies 6 symbols.

When the position of the DMRS symbol is located in an odd-numbered symbol of 13 symbols occupied by the overall long-duration uplink control signaling, two symbols of the odd-numbered symbols in the 7 symbols included in the first frequency hopping part may be used to transmit the DMRS, and two symbols of even-numbered symbols in the 6 symbols included in the second frequency hopping part may be used to transmit the DMRS, and according to the above determining manner, the obtained DMRS symbol position may be: the third symbol and the fifth symbol in the first frequency hopping part, the second symbol and the sixth symbol in the second frequency hopping part, that is, the third, fifth, ninth and thirteenth symbols of 13 symbols occupied by the overall long-duration uplink control signaling are used for transmitting the DMRS.

Taking fig. 6B as an example, when the number of symbols occupied by the long-term long uplink control signaling is 13 symbols, each of two frequency hopping parts occupied by the long-term long uplink control signaling has two symbols for transmitting the DMRS. The first hopping part occupies 7 symbols and the second hopping part occupies 6 symbols.

When the positions of the DMRS symbols are located in odd-numbered symbols of the symbols included in each frequency hopping part, that is, two symbols of the odd-numbered symbols are used to transmit the DMRS among the 7 symbols included in the first frequency hopping part, and two symbols of the odd-numbered symbols of the 6 symbols included in the second frequency hopping part are used to transmit the DMRS, according to the above determination method, the third symbol and the fifth symbol in the first frequency hopping part, and the third symbol and the fifth symbol in the second frequency hopping part, that is, the third symbol, the fifth symbol, the tenth symbol, and the twelfth symbol of the 13 symbols occupied by the overall long-duration uplink control signaling are used to transmit the DMRS.

EXAMPLE III

Taking the example that the first frequency hopping part includes X symbols, two symbols are selected on even-numbered bit symbols among the X symbols included in the first frequency hopping part to transmit the DMRS. The manner in which the second frequency hopping part determines the DMRS symbol may refer to determining the position of the DMRS symbol in the first frequency hopping part, and is not repeated here.

Wherein the selection rule may be: the selected position of the DMRS symbols can minimize the maximum distance between every two adjacent UCI symbols and the minimum number of the symbols, namely each of the X-2 UCI symbols is closer to the two selected DMRS symbols, thereby ensuring the best transmission performance.

For example, fig. 7A (1), DMRS symbols are located at the second and sixth, in this case, the maximum distance of the DMRS symbol closest to all UCI symbols is 2, the corresponding UCI symbol is the fourth symbol, the distance is the smallest among all possibilities, and the symbol with the distance of 2 is only the fourth symbol, i.e., the number of such symbols is also the smallest.

Similarly, the first hopping part comprises X consecutive symbols, X being from 6 to 14 in length, and the positions of two DMRS symbols therein are confirmed as follows:

for the case where X is 6, the DMRS symbols are located at the second and sixth symbol positions as shown in fig. 7A (1), and at the second and fourth symbol positions as shown in fig. 7A (2).

For the case where X is 7, the DMRS symbols are located at the second symbol and the sixth symbol positions as shown in fig. 7B.

For the case where X is 8, the DMRS symbols are located at the second and sixth symbol positions as shown in fig. 7C.

For the case where X is 9, the DMRS symbols are located at the second and sixth symbol positions as shown in fig. 7D (1), at the second and eighth symbol positions as shown in fig. 7D (2), and at the fourth and eighth symbol positions as shown in fig. 7D (3).

For the case where X is 10, the DMRS symbols are located at the second and eighth symbol positions as shown in fig. 7E.

For the case where X is 11, the DMRS symbols are located at the fourth and eighth symbol positions as shown in fig. 7F (1), at the second and eighth symbol positions as shown in fig. 7F (2), and at the fourth and tenth symbol positions as shown in fig. 7F (3).

For the case where X is 12, the DMRS symbols are located at the fourth and tenth symbol positions as shown in fig. 7G.

For the case where X is 13, the DMRS symbols are located at the fourth and tenth symbol positions as shown in fig. 7H.

For the case where X is 14, the DMRS symbols are located at the fourth and tenth symbol positions as described in fig. 7I (1), and at the fourth and twelfth symbol positions as described in fig. 7I (2).

Example four

Taking the example that the first frequency hopping part includes X symbols, two symbols are selected on odd-numbered bit symbols among the X symbols included in the first frequency hopping part to transmit the DMRS. The manner in which the second frequency hopping part determines the DMRS symbol may refer to determining the position of the DMRS symbol in the first frequency hopping part, and is not repeated here.

Referring to fig. 8A (1), DMRS symbol bits are the third and fifth symbol positions of the first hopping part, and at this time, the maximum distance of the DMRS symbol closest to all UCI symbols is 2, the corresponding UCI symbol is the 1 st symbol, the distance is the smallest among all possibilities, and the symbol having the distance of 2 has only the fourth symbol, i.e., the number of such symbols is also the smallest.

for the case where X is 6, the DMRS symbols are located at the third and fifth symbol positions as shown in fig. 8A (1), and the DMRS symbols are located at the first and fifth symbol positions as shown in fig. 8A (2).

For the case where X is 7, as shown in fig. 8B (1), DMRS symbols are located at the third and seventh symbol positions; as shown in fig. 8B (2), DMRS symbols are located at the third and fifth symbol positions; as shown in fig. 8B (3), DMRS symbols are located at the first and fifth symbol positions.

For the case where X is 8, the DMRS symbols are located at the third and seventh symbol positions as shown in fig. 8C.

For the case where X is 9, the DMRS symbols are located at the third and seventh symbol positions as shown in fig. 8D.

For the case where X is 10, the DMRS symbols are located at the third and seventh symbol positions as shown in fig. 8E (1), and at the third and ninth symbol positions as shown in fig. 8E (2).

For the case where X is 11, the DMRS symbols are located at the third and ninth symbol positions as shown in fig. 8F.

For the case where X is 12, the DMRS symbols are located at the third and ninth symbol positions as shown in fig. 8G.

For the case where X is 13, the DMRS symbols are located at the third and ninth symbol positions as shown in fig. 8H (1), at the third and eleventh symbol positions as shown in fig. 8H (2), and at the fifth and eleventh symbol positions as shown in fig. 8H (3).

For the case where X is 14, the DMRS symbols are located at the third and eleventh symbol positions as shown in fig. 8I (1), and at the fifth and eleventh symbol positions as shown in fig. 8I (2).

Specifically, the position of the DMRS symbol may also be represented by table 1 or table 2, and table 1 and table 2 are only one example.

EXAMPLE five

Two symbols, which assume a central position in each frequency hopping part, are used for transmitting the DMRS.

For X consecutive symbols on the same frequency domain resource as one hopping part, taking the first hopping part comprising X symbols as an example, the way to confirm two DMRS symbols in the first hopping part is as follows:

when X is an even number, the position of the DMRS symbol in the first hopping part is

When X is odd, the position of DMRS symbol in the first hopping part is

Or

For example, as shown in fig. 9(1), when one frequency hopping part includes 6 consecutive symbols, DMRS symbols are located at third and fourth symbols; as shown in fig. 9(2), 9(3), when one frequency hopping part includes 7 consecutive symbols, the positions of the DMRS symbols are the third and fourth symbols, or the fourth and fifth symbols; as shown in fig. 9(4), when one frequency hopping part includes 8 consecutive symbols, the DMRS symbols are located at the fourth and fifth symbols. For example, the first and second hopping parts each have 6 symbols, as shown in fig. 10(1), the third and fourth symbols of the first hopping part are DMRS symbols, and the third and fourth symbols of the second hopping part are DMRS symbols. Of course, the number of symbols included in the two frequency hopping parts may not be equal, for example, the first frequency hopping part includes 8 symbols, and the second frequency hopping part includes 6 symbols, as shown in fig. 10(2), then the fourth and fifth symbols of the first frequency hopping part are DMRS symbols, and the third and fourth symbols of the second frequency hopping part are DMRS symbols.

EXAMPLE six

Two symbols, which assume symmetric positions in each frequency hopping part, are used to transmit the DMRS. Wherein, the selection of the position of the DMRS symbol satisfies the following conditions: the selected position of the DMRS symbols can minimize the maximum distance between every two adjacent UCI symbols and the minimum number of the symbols, namely each of the X-2 UCI symbols is closer to the two selected DMRS symbols, thereby ensuring the best transmission performance.

For X consecutive symbols on the same frequency domain resource as a hopping part, X may take an integer of 8 to 14. X consecutive symbols on the same frequency domain resource may serve as a first frequency hopping part and a second frequency hopping part, where the number of symbols included in the first frequency hopping part and the number of symbols included in the second frequency hopping part may be equal or unequal, and the two DMRS symbol positions are determined in the following manner: position of DMRS symbol is

Or

As shown in fig. 11, the position by DMRS symbol is

The corresponding positions are given.

As shown in fig. 11(1), when one frequency hopping part includes 8 consecutive symbols, DMRS symbols are located at the second and seventh symbols; as shown in fig. 11(2), when one frequency hopping part includes 9 consecutive symbols, the DMRS symbols are located at the third and seventh symbols; as shown in fig. 11(3), when one frequency hopping part includes consecutive 10 symbols, DMRS symbols are located at the third and eighth symbols; as shown in fig. 11(4), when one frequency hopping part includes consecutive 11 symbols, the DMRS symbol is located at the third and ninth symbols; as shown in fig. 11(5), when one frequency hopping part includes consecutive 12 symbols, DMRS symbols are located at the third and tenth symbols; as shown in fig. 11(6), when one frequency hopping part includes 13 consecutive symbols, the DMRS symbol is located at the fourth and tenth symbols, and as shown in fig. 11(7), when one frequency hopping part includes 14 consecutive symbols, the DMRS symbol is located at the fourth and eleventh symbols.

Specifically, the position of the DMRS symbol may also be represented by table 3, and table 3 is only one example.

TABLE 3

Number of consecutive symbols of same frequency resource	Position of DMRS symbol
6	{2,5}
7	{2,6}
8	{2,7}
9	{3,7}

11	{3,9}
12	{3,10}

The third case is specifically illustrated by the following example seven.

Example seven:

in the above, each frequency hopping part includes one DMRS symbol or two DMRS symbols. In long-time and long-time uplink control signaling transmission, one frequency hopping part may contain one DMRS symbol, and the other frequency hopping part may contain two DMRS symbols. Optionally, X symbols may be used as a boundary, and when the number of symbols of a certain frequency hopping part is less than X, then 1 DMRS symbol is included in the frequency hopping part, and when the number of symbols of a certain frequency hopping part is greater than or equal to X, then 2 DMRS symbols are included in the frequency hopping part. The two hopping parts may be in one time slot, two time slots or more than two time slots. For each frequency hopping part, when the frequency hopping part has only one DMRS symbol, the position of the DMRS symbol may be determined in such a manner that the frequency hopping part described in the first case contains 1 DMRS symbol; when the frequency hopping part contains two DMRS symbols, the frequency hopping part may determine the positions of the DMRS symbols in a manner that the frequency hopping part contains 2 DMRS symbols as described in the second case.

For example, as shown in fig. 12A, the DMRS is located at an odd-numbered bit of the entire long-term uplink control signaling. As shown in fig. 12A (1), the first frequency hopping part includes 6 symbols, and the second frequency hopping part includes 5 symbols, then the two DMRS symbols included in the first frequency hopping part are located at the third and fifth symbol positions of the first frequency hopping part, respectively, and the 1 DMRS symbol included in the second frequency hopping part is the third symbol of the second frequency hopping part. As shown in fig. 12A (2), the first frequency hopping part includes 5 symbols, and the second frequency hopping part includes 6 symbols, then the 1 DMRS symbol included in the first frequency hopping part is the third symbol of the first frequency hopping part, and the two DMRS symbols included in the second frequency hopping part are located at the second and fourth symbol positions of the second frequency hopping part, respectively.

For example, as shown in fig. 12B, DMRS is located at even bits of the entire long-term uplink control signaling. As shown in fig. 12B (1), the first frequency hopping part includes 5 symbols, and the second frequency hopping part includes 6 symbols, then the 1 DMRS symbol included in the first frequency hopping part is the second symbol of the first frequency hopping part, and the two DMRS symbols included in the second frequency hopping part are located at the first and fifth symbol positions of the second frequency hopping part, respectively. As shown in fig. 12B (2), the first frequency hopping part includes 6 symbols, and the second frequency hopping part includes 5 symbols, then the two DMRS symbols included in the first frequency hopping part are located at the second and sixth symbol positions of the first frequency hopping part, respectively, and the 1 DMRS symbol included in the second frequency hopping part is the fourth symbol of the second frequency hopping part. As shown in fig. 12C (1), the first 6 symbols are the first hop section, the DMRS symbol included in the first hop section is located in the third symbol of the first hop section, the last 7 symbols are the second hop section, and the two DMRS symbols included in the second hop section are located in the third and fifth symbols of the second hop section. As shown in fig. 12C (2), the first 7 symbols are a first hopping part, the two DMRS symbols included in the first hopping part are located at the third and fifth symbols, the last 6 symbols are a second hopping part, and the 1 symbol DMRS included in the second hopping part is located at the third symbol of the second hopping part. As shown in fig. 12D (1), the first 6 symbols are a first hopping part, the first hopping part includes 1 DMRS located in the fourth symbol of the first hopping part, the last 7 symbols are a second hopping part, and the two DMRS symbols included in the second hopping part may be located in the second and sixth symbols of the second hopping part. As shown in fig. 12D (2), the first 7 symbols are a first frequency hopping part, two DMRS symbols included in the first frequency hopping part may be located at the second and sixth symbols, the last 6 symbols are a second frequency hopping part, and 1 DMRS included in the second frequency hopping part may be located at the fourth symbol of the second frequency hopping part.

The two frequency hopping parts described in fig. 12A to 12D each include the same number of UCI symbols, and optionally, the terminal device transmits the first frequency hopping part using the first beam and transmits the second frequency hopping part using the second beam.

For example, as shown in fig. 13(1), the first 6 symbols are the first frequency hopping part, the two DMRS symbols included in the first frequency hopping part may be located in the second and fifth symbols of the first frequency hopping part, the last 5 symbols are the second frequency hopping part, and the 1 DMRS symbol included in the second frequency hopping part is located in the third symbol of the second frequency hopping part. As shown in fig. 13(2), the first 5 symbols are a first hopping part, the first hopping part may include 1 DMRS symbol located in the third symbol of the first hopping part, the last 6 symbols are a second hopping part, and the second hopping part may include two DMRS symbols located in the second and fifth symbols of the second hopping part. As shown in fig. 13(3), the first 6 symbols are a first hopping part, the 1 DMRS symbol included in the first hopping part may be located in the fourth symbol of the first hopping part, the last 7 symbols are a second hopping part, and the two DMRS symbols included in the second hopping part may be located in the second and sixth symbols of the second hopping part. As shown in fig. 13(4), the first 7 symbols are a first frequency hopping part, the two DMRS symbols included in the first frequency hopping part may be located at the second and sixth symbols of the first frequency hopping part, the last 6 symbols are a second frequency hopping part, and the 1 DMRS symbol included in the second frequency hopping part may be located at the fourth symbol of the second frequency hopping part. As shown in fig. 13(5), the first 7 symbols are a first frequency hopping part, the first frequency hopping part may include 1 DMRS symbol located in the fourth symbol of the first frequency hopping part, the last 8 symbols are a second frequency hopping part, and the second frequency hopping part may include two DMRS symbols located in the second and seventh symbols of the second frequency hopping part. As shown in fig. 13(6), the first 8 symbols are a first frequency hopping part, the two DMRS symbols included in the first frequency hopping part may be located in the second and seventh symbols, the last 7 symbols are a second frequency hopping part, and the 1 DMRS symbol included in the second frequency hopping part may be located in the fourth symbol of the second frequency hopping part.

The two frequency hopping parts described in fig. 12A, fig. 12B, fig. 12C, fig. 12D, and fig. 13 each include the same number of UCI symbols, and optionally, the terminal device may transmit the first frequency hopping part using the first beam and transmit the second frequency hopping part using the second beam.

In order to solve the second problem, in the embodiment of the present application, the same uplink control information is repeatedly transmitted through at least one long-duration uplink control signaling, where the at least one long-duration uplink control signaling may be located in at least one timeslot, and may hop within the timeslot or may not hop within the timeslot.

Referring to fig. 14, a flowchart of a method for transmitting a long-duration uplink control signaling provided in the embodiment of the present application is shown, where the method is used to solve a second existing problem, and the method includes:

s1401, a base station sends configuration information to a terminal device, wherein the configuration information is used for indicating the terminal device to transmit at least one long-duration uplink control signaling on a first part and a second part, and the at least one long-duration uplink control signaling carries uplink control information with more than 2 bits; wherein the first portion and the second portion are located in at least one time slot in a time domain, and uplink control information transmitted in the first portion is the same as uplink control information transmitted in the second portion. The uplink control information transmitted in the first part and the second part is larger than 2 bits.

The first portion and the second portion are located in at least one time slot in the time domain, which means that the first portion and the second portion are located in at least one time slot in the time domain as a whole.

S1402, the terminal device obtains the configuration information. Specifically, the terminal device receives configuration information sent by the base station.

S1403, the terminal device transmits at least one long-duration uplink control signaling on the first part and the second part based on the configuration information, where the at least one long-duration uplink control signaling carries uplink control information greater than 2 bits; wherein the first portion and the second portion occupy at least one time slot in a time domain, and uplink control information transmitted in the first portion is the same as uplink control information transmitted in the second portion.

S1404, the base station receives at least one long-duration uplink control signaling from the terminal device on the first part and the second part.

Optionally, the terminal device transmits the two parts by using one beam, or transmits different parts by using different beams, that is, the terminal device transmits the first part by using the first beam and transmits the second part by using the second beam.

And after the base station receives at least one long-time uplink control signaling sent by the terminal equipment on the first part and the second part, the base station respectively receives symbols corresponding to the DMRS, measures channel information on the symbols corresponding to the UCI, and then divides the signals received by the symbols corresponding to the UCI by the corresponding channel information and decodes the signals to obtain the uplink control information.

Because the same uplink control information is transmitted repeatedly, each part of one long-time uplink control signaling for transmitting the same uplink control information or each part of a plurality of long-time uplink control signaling is required to have the same capacity, and the uplink control information with the same load can be borne. The capacity matching method of the first part and the second part is specifically described below from three perspectives of the time domain, the frequency domain, and the code rate, that is, how to make the capacity of the first part and the capacity of the second part the same. In the specific implementation, the time domain, the frequency domain, and the code rate may be implemented individually or in combination.

The capacity matching method of the first and second parts is first described in detail from the time domain perspective.

The two parts included in at least one long-duration uplink control signaling repeatedly transmit the same uplink control information, that is, the uplink control information transmitted by the two parts is the same. If a long-duration uplink control signaling includes two frequency hopping part symbols with different lengths, the capacity of the two frequency hopping parts may be different, and waste may be caused. For repeated transmission of the same uplink control information by multiple long-duration uplink control signaling, for example, the symbol lengths of two long-duration uplink control signaling are different, which may cause different capacities of two uplink control information, resulting in waste. For the two cases, the first part and the second part are defined in this embodiment of the present application, where the first part and the second part may be two frequency hopping parts included in one long-duration uplink control signaling, respectively, the first part and the second part may also be one long-duration uplink control signaling, and the first part and the second part bear the same uplink control information, respectively. The first portion and the second portion may be in the same time slot or in different time slots. In order to enable the first part and the second part to carry the same uplink control information, a part with a larger number of symbols in the first part and the second part may be made to repeatedly transmit DMRS or UCI symbols. See, in particular, examples eight through ten.

Example eight

And when the number of symbols occupied by the first part is greater than that occupied by the second part, the number of symbols used for transmitting the reference signals DMRS in the first part is greater than that used for transmitting the reference signals DMRS in the second part, namely, the part with more symbols in the first part and the second part adopts a mode of repeatedly transmitting the DMRS.

The first part comprises X symbols and the second part comprises Y symbols, wherein X is larger than or equal to Y.

In a first possible implementation manner, the X symbols included in the first part are located on the same frequency resource, and the Y symbols included in the second part are located on the same frequency resource. When X is Y +1, 2 DMRS symbols are included on the first portion and 1 DMRS symbol is included on the second portion, thereby ensuring that the number of UCI symbols in the two portions is equal. Specifically, the positions of DMRS symbols included in the first frequency hopping part and the second frequency hopping part can be determined in the seventh implementation. For example, the second portion includes 1 DMRS symbol located as far as possible in the middle of the second portion, and when Y is an odd number, the (Y +1)/2 th symbol in the first portion is a DMRS symbol for transmitting a DMRS; when Y is an even number, the Y/2 th symbol in the second part is a DMRS symbol, or the Y/2+1 th symbol in the second part is a DMRS symbol and is used for transmitting DMRS; for the position of the DMRS symbol included in the first portion, refer to the schemes described in embodiments two to six, and details are not described here.

For example, as shown in fig. 15(1), a DMRS symbol is located on one or two symbols of each fractional odd-numbered symbol, a first portion includes 6 symbols, a second portion includes 5 symbols, a DMRS is located on the third symbol position of the second portion, and DMRSs are located on the third and fifth symbol positions of the first portion, in which case, a DMRS symbol is located on each fractional odd-numbered symbol. As shown in fig. 15(2), the DMRS symbol is located on one or two of the odd-bit symbols of the symbols included in the whole of the first part and the second part, the first part has 6 symbols, the second part has 5 symbols, the DMRS symbol is located on the third symbol position of the second part, and the DMRS symbol is located on the second and fourth symbol positions of the first part, in this case, the DMRS symbol is located on the odd-bit symbol of the symbols included in the whole of the first part and the second part.

In a second possible implementation manner, the first part and the second part respectively use frequency hopping transmission, and when X is Y +1, the first part has one more DMRS symbol than the second part, thereby ensuring that the number of UCI symbols in the two parts is equal. The DMRS symbols may be located on the odd-bit symbols in each portion, for example, as shown in fig. 16(1), the first portion has 6 symbols, the second portion has 5 symbols, the first, third and fifth symbols in the first portion are DMRS symbols, and the first and third symbols in the second portion are DMRS symbols, in which case, the DMRS symbols are located on the odd-bit symbols in each portion. The DMRS symbols may be located on odd-bit symbols of the symbols included in the whole of the first part and the second part, as shown in fig. 16(2), where the first part has 6 symbols, the second part has 5 symbols, the first and third symbols of the second part are DMRS symbols, and the second, fourth and sixth symbols of the first part are DMRS symbols, and in this case, the DMRS symbols are located on odd-bit symbols of the symbols included in the whole of the first part and the second part.

In a third possible implementation manner, the first part and the second part respectively use frequency hopping transmission, and when X is Y +1, the first part has one more DMRS symbol than the second part, thereby ensuring that the number of UCI symbols in the two parts is equal. One frequency hopping part in the first part can be configured with 2 DMRS symbols, the other frequency hopping part in the first part can be configured with one DMRS symbol, and two frequency hopping parts in the second part are respectively configured with one DMRS symbol. When 2 DMRS symbols are configured for one frequency hopping part in the first part, the specific configuration method may refer to example five and example six, that is, 2 DMRS symbols are located in the middle of the frequency hopping part in the first part or at the symmetrical position of the frequency hopping part, and the configuration manner of configuring the frequency hopping part of one DMRS symbol may refer to example one, that is, one DMRS symbol is located in the middle of the frequency hopping part.

When 2 DMRS symbols are located in the middle of one frequency hopping section in the first section, as shown in fig. 17A, the first section includes 11 symbols, two frequency hopping sections include 6 symbols and 5 symbols, respectively, the third and fourth symbols in the frequency hopping section including 6 symbols are DMRS symbols, the third symbol in the frequency hopping section including 5 symbols is a DMRS symbol, the second section includes 10 symbols, each frequency hopping section includes 5 symbols, and the third symbol in each frequency hopping section is a DMRS symbol.

When 2 DMRS symbols are located at a symmetrical position of one frequency hopping part in the first part, as shown in fig. 17B, the first part includes 11 symbols, two frequency hopping parts include 6 symbols and 5 symbols, respectively, the second and fifth symbols in the frequency hopping part including 6 symbols are DMRS symbols, the third symbol in the frequency hopping part including 5 symbols is a DMRS symbol, the second part includes 10 symbols, each frequency hopping part includes 5 symbols, and the third symbol in each frequency hopping part is a DMRS symbol.

In a fourth possible implementation manner, the first part and the second part respectively use frequency hopping transmission, and when X is Y +1, the first part has one more DMRS symbol than the second part, thereby ensuring that the number of UCI symbols in the two parts is equal. The Y symbols in the first part repeatedly transmit the Y symbols in the second part, and the remaining one symbol in the first part transmits the DMRS, as shown in fig. 18(1) and fig. 18(2), and the remaining one symbol is located at the first symbol at the beginning or the last symbol at the end of the first part.

The above implementations have enumerated the case that the first part has one more symbol than the second part, and when the first part has two more symbols than the second part, both hopping parts of the first part contain 2 DMRS symbols, and both hopping parts of the second part contain 1 DMRS symbol; at this time, the first portion has 2 more DMRS symbols than the second portion. In the scheme provided in embodiments one to seven, the configuration of the positions of two DMRS symbols included in each frequency hopping section in the first section may refer to the manners described in embodiments two to seven, and the configuration of the position of one DMRS symbol included in each frequency hopping section in the second section may refer to the manner described in embodiment one.

Example nine

And the part with more symbols in the first part and the second part adopts a mode of repeatedly transmitting partial UCI symbols or all UCI symbols. The number of symbols occupied by the first part is X, the number of symbols occupied by the second part is Y, and X > Y; the uplink control information transmitted by at least one symbol in the X-Y symbols occupied by the first part is the same as the uplink control information transmitted by at least one symbol in the Y symbols occupied by the first part, and X, Y are positive integers

The above situation needs to satisfy the following conditions at the same time: the value of X may not be 7 and the value of Y may not be 6, and the number of DMRS symbols included in the first portion is not 3 and the number of DMRS symbols included in the second portion is not 3. I.e. excluding the case where 4 of the 7 symbols of the first part are UCI symbols, 3 DMRS symbols, and 3 UCI symbols and 3 DMRS symbols of the 6 symbols of the second part.

The above situation needs to satisfy the following conditions at the same time: the value of X may not be 7 and the value of Y may not be 6, and when the first portion and the second portion each include 2 DMRS symbols, the DMRS is not located in the second and sixth symbols of the first portion, and the DMRS is not located in the second and sixth symbols of the second portion. Namely, excluding the case where 5 of the 7 symbols of the first portion are UCI symbols, DMRS is located in the second and sixth symbols of the first portion, 4 of the 6 symbols of the second portion are UCI symbols, and DMRS is located in the second and sixth symbols of the second portion.

At least one of the remaining Y UCI symbols in the first portion is repeatedly transmitted over the first portion by X-Y symbols. The remaining Y symbols of the first portion and the Y symbols of the second portion transmit the same content (UCI and DMRS). The first portion and the second portion may be located on at least one time slot.

Optionally, the number of symbols used for carrying uplink control information in the X symbols of the first portion is L1, the number of symbols used for carrying uplink control information in the Y symbols of the second portion is L2, the number of symbols is L1> L2, a signal transmitted on at least one of the L1-L2 symbols occupied by the first portion is the same as a signal transmitted on at least one of the L2 symbols occupied by the first portion, and both L1 and L2 are positive integers. Wherein X-L1 may be equal to Y-L2, i.e., the number of DMRS symbols in the first part may be the same as the number of DMRS symbols in the second part.

Alternatively, the above case needs to satisfy the following conditions at the same time: the value of L1 may be other than 4 and the value of L2 may be other than 3, and the number of symbols included in the first part is other than 7 and the number of symbols included in the second part is other than 6. I.e. excluding the case where 4 of the 7 symbols of the first part are UCI symbols, 3 DMRS symbols, and 3 UCI symbols and 3 DMRS symbols of the 6 symbols of the second part. I.e. excluding the case where 4 of the 7 symbols of the first part are UCI symbols, 3 DMRS symbols, and 3 UCI symbols and 3 DMRS symbols of the 6 symbols of the second part.

Optionally, the above conditions need to satisfy the following conditions at the same time: the value of L1 may not be 5 and the value of L2 may not be 4, and the number of symbols included in the first portion is not 7, the number of symbols included in the second portion is not 6, and the DMRS is not located in the second and sixth symbols of the first portion, and the DMRS is not located in the second and sixth symbols of the second portion. I.e. excluding the case where 5 of the 7 symbols of the first part are UCI symbols, 2 DMRS symbols, 4 of the 6 symbols of the second part are UCI symbols, and 2 DMRS symbols, and the DMRS is located at the second and sixth symbols of the first part, and the DMRS is located at the second and sixth symbols of the second part.

Taking the same number of symbols for transmitting DMRSs in the first and second parts as an example, as shown in fig. 19A, the first part X is 7, the second part Y is 5, 5 symbols in the first part and 5 symbols in the second part transmit the same uplink control information, and DMRSs are transmitted in both the third symbol in the first part and the third symbol in the second part; in addition, the sixth and seventh symbols of the first part repeatedly transmit part or all of the uplink control information. Optionally, the sixth and seventh symbols of the first part are the same as the fourth and fifth symbols of the first part, or the sixth and seventh symbols of the first part are the same as any one or two of the remaining UCI-carrying symbols of the first part. By transmitting the same signal in these symbols, the base station can directly combine the signals on the symbols without increasing the decoding load.

Taking the case that the number of DMRS symbols on the first part is greater than the number of DMRS symbols on the second part, and the number x1 of symbols carrying UCI on the first part is greater than the number y1 of symbols carrying UCI on the second part; at this time, x1-y1 symbols carrying more UCI symbols on the first part than the second part, optionally, x1-y1 symbols on the first part may be the same as at least one of y1 symbols on the first part, repeatedly transmit part or all of the uplink control information. The first portion and the second portion may be located on at least one time slot. As shown in (1) or (2) of fig. 19B, the first part X is 9, the second part Y is 5, the same uplink control information and DMRS are transmitted in the 5 symbols of the first part and the 5 symbols of the second part, and the DMRS is transmitted in the third symbol of the first part and the third symbol of the second part; in addition, a seventh symbol of the first part transmits the DMRS; referring to (1) of fig. 19B, the sixth, eighth and ninth symbols of the first part repeatedly transmit part or all of the uplink control information, or, referring to (2) of fig. 19B, the first, fifth and ninth symbols of the first part repeatedly transmit part or all of the uplink control information. Optionally, referring to (1) of fig. 19B, the sixth, eighth and ninth symbols of the first part are the same as at least one of the remaining UCI-carrying symbols of the first part, or, referring to (2) of fig. 19B, the first, fifth and ninth symbols of the first part are the same as at least one of the remaining UCI-carrying symbols of the first part. By transmitting the same signal in these symbols, the base station can directly combine the signals on the symbols without increasing the decoding load.

Example ten

Embodiment ten describes a manner in which a part of the first part and the second part, which has a larger number of symbols, uses a combination of UCI and DMRS for repeated transmission. Let the first part contain X symbols and the second part contain Y symbols, where X ═ kY, k is a positive integer greater than or equal to 2, such as k ═ 2,3,4, etc. And the X symbols occupied by the first part are used for repeatedly transmitting a symbol group, and the symbol group comprises uplink control information and DMRS which are used for transmitting Y symbols occupied by the second part.

Specifically, the transmission of the combination of the Y symbols of the second part is repeated k times in the first part. For example, as shown in (1) in fig. 20, the second part of 4 symbols forms a combination, and is composed of three UCI-bearing symbols and one DMRS-bearing symbol, the first part of 8 symbols is divided into two groups, and each group of 4 symbols repeats the combination composed of three UCI-bearing symbols and one DMRS-bearing symbol; for example, as shown in (2) in fig. 20, the second part of 5 symbols forms a combination of three UCI-bearing symbols and one DMRS-bearing symbol, the first part of 10 symbols is divided into two groups of 5 symbols, and each group of 5 symbols repeats a combination of four UCI-bearing symbols and one DMRS-bearing symbol.

Optionally, the terminal device transmits the k combinations on the first part using at least one beam and transmits the second part using another beam. As shown in (3) in fig. 20, the terminal transmits the second part using beam x, one combination of the first parts using beam y, and another combination of the first parts using beam z; the beams x, y, z may be the same beam or different beams.

The capacity matching method of the first and second parts is specifically described below from the perspective of the frequency domain.

And at least one long-time uplink control signaling transmits the same uplink control information. For one uplink control signaling, if the symbol lengths of the two frequency hopping parts are different, the capacities of the two frequency hopping parts may be different, which results in waste. For multiple uplink control signaling to repeatedly transmit the same uplink control information, if the symbol lengths of two long-duration uplink control signaling are different, the capacity of the two uplink control information may be different, and waste may be caused. In order to enable the first part and the second part to carry the same uplink control information, the frequency domain resources with more symbols and less coverage in the first part and the second part can be made, the frequency domain resources with less symbols and more coverage in the second part can be made, and the time-frequency domain resources of the two parts are made to be close to each other. That is, when the number of symbols occupied by the first portion is greater than the number of symbols occupied by the second portion, the frequency domain resources occupied by the first portion are smaller than the frequency domain resources occupied by the second portion.

EXAMPLE eleven

The first part comprises X symbols, the second part comprises Y symbols, the first part covers M Physical Resource Blocks (PRBs) in the frequency domain, the second part covers N PRBs in the frequency domain, and if X is larger than Y, M is smaller than N.

For example, as shown in fig. 21, the first part includes 5 symbols, the second part includes 4 symbols, the first part covers less frequency domain resources, i.e., 3 PRBs, and the second part covers more frequency domains, i.e., 4 PRBs.

After the base station receives the at least one long-duration uplink control signaling sent by the terminal equipment in the manner on the first part and the second part, the base station respectively receives symbols corresponding to the DMRSs, measures channel information on the UCI corresponding symbols, and then divides the signals received by the UCI corresponding symbols by the corresponding channel information and decodes the divided signals to obtain control information.

The capacity matching method of the first part and the second part is specifically described from the viewpoint of the code rate as follows.

And transmitting the same uplink control information on at least one long-time uplink control signaling. For a long-duration uplink control signaling, if the symbol lengths of the two frequency hopping parts are different, the capacities of the two frequency hopping parts may be different, which results in waste. For multiple long-duration uplink control signaling to repeatedly transmit the same uplink control information, if the symbol lengths of two long-duration uplink control signaling are different, the capacity of the two uplink control information may be different, and waste may be caused. In order to enable the first portion and the second portion to carry the same uplink control information, a portion with a larger number of symbols in the first portion and the second portion may be made to use a lower coding rate, and a portion with a smaller number of symbols may be made to use a higher coding rate, that is, when the number of symbols occupied by the first portion is greater than the number of symbols occupied by the second portion, the coding rate used for transmitting the first portion is less than the coding rate used for transmitting the second portion.

Example twelve

And enabling the first part to comprise X symbols, enabling the second part to comprise Y symbols, enabling the coding rate of the first part to be a and the coding rate of the second part to be b, and enabling a to be smaller than b if X is larger than Y.

For example, as shown in fig. 22, the first part includes 5 symbols, the second part includes 4 symbols, the first part uses a lower coding rate, such as 1/4, and the second part uses a higher coding rate, such as 1/3.

Optionally, in this embodiment of the present application, when the terminal device transmits the first part and the second part included in the at least one uplink control signaling based on the configuration information, the method may specifically be implemented as follows:

the terminal device transmits the first portion and the second portion in at least one beam based on the configuration information.

The first part and the second part are transmitted by using different beams, respectively, as described in detail in the thirteenth embodiment.

EXAMPLE thirteen

For the case that the first part and the second part have the same number of symbols, the description of (1), (2), and (3) in fig. 23A can be referred to. Referring to (1) in fig. 23A, the first 6 symbols are the first part, and the first 6 symbols are located in the same frequency domain position. The last 6 symbols are the second part, and the last 6 symbols are located in the same frequency domain position. The first and second portions transmit the same signal. The signals transmitted by the first three symbols in the first part are the same as the signals transmitted by the last three symbols in the first part, and the signals transmitted by the first three symbols in the second part are the same as the signals transmitted by the last three symbols in the second part. Wherein, the first 3 symbols of the first part can be transmitted by adopting a beam x, and the last 3 symbols of the first part are transmitted by adopting a beam y; the first 3 symbols in the second part are transmitted using beam x and the last 3 symbols are transmitted using beam y.

Referring to (2) in fig. 23A, the first 6 symbols are the first part, and the first 3 symbols of the first part and the last 3 symbols of the first part are located at different frequency domain positions. The last 6 symbols are the second part, and the first 3 symbols and the last 3 symbols of the second part are located at different frequency domain positions. The first and second portions transmit the same signal. The signals transmitted by the first three symbols in the first part are the same as the signals transmitted by the last three symbols in the first part, and the signals transmitted by the first three symbols in the second part are the same as the signals transmitted by the last three symbols in the second part. Wherein, the first 3 symbols of the first part can be transmitted by adopting a beam x, and the last 3 symbols of the first part are transmitted by adopting a beam y; the first 3 symbols in the second part are transmitted using beam x and the last 3 symbols are transmitted using beam y.

Referring to (3) in fig. 23A, the first 6 symbols are the first part, and the first part is frequency hopping transmission, that is, the first 3 symbols of the first part and the last 3 symbols of the first part are located at different frequency domain positions. The last 6 symbols are the second part, which is frequency hopping transmission, i.e. the first 3 symbols of the second part and the last 3 symbols of the second part are located in different frequency domain positions. The first and second portions transmit the same signal. Wherein the first portion is transmitted using beam x and the second portion is transmitted using beam y.

For the case where the first and second fractional symbols are different, as described in (1) in fig. 23B and (2) in fig. 23B, the first fractional symbol is 6, the terminal transmits using the beam y, the second fractional symbol is 5, and the terminal transmits using the beam x.

On the receiving side, after receiving the symbols corresponding to the DMRSs, the base station measures channel information on the symbols corresponding to the UCI, and then divides the signals received by the symbols corresponding to the UCI by the corresponding channel information and decodes the divided signals to obtain control information.

In order to solve the third problem, in this embodiment, the terminal device repeatedly transmits the same uplink control information with a bit number less than or equal to 2 on at least two time slots by using at least one long-duration uplink control signaling.

Referring to fig. 24, a flowchart of a method for transmitting a long-duration uplink control signaling provided in the embodiment of the present application is shown, where the method is used to solve a third existing problem, and the method includes:

s2401, the base station sends the configuration information to the terminal device.

S2402, the terminal device obtains the configuration information.

S2403, the terminal device repeatedly transmits the same uplink control information with less than or equal to 2 bits on at least two timeslots by using at least one long-duration uplink control signaling based on the configuration information.

S2404, the base station receives the at least one long-duration uplink control signaling transmitted by the terminal device on at least two timeslots.

In a symbol included in each of at least two time slots occupied by the at least one long-duration uplink control signaling, all odd bits are used for transmitting a reference signal DMRS; or, in the symbol of each frequency hopping part included in each of at least two time slots occupied by the at least one long-duration uplink control signaling, all odd bits are used for transmitting a reference signal DMRS; or, in the symbol included in each of the at least two time slots occupied by the at least one long-duration uplink control signaling, all even-numbered bits are used for transmitting the DMRS; or, in the symbol of each frequency hopping part included in each of at least two time slots occupied by the at least one long-duration uplink control signaling, all even-numbered bits are used for transmitting a reference signal DMRS; or, in all symbols included in at least two time slots occupied by the at least one long-duration uplink control signaling, all odd bits are used for transmitting the DMRS; or, in all symbols included in at least two time slots occupied by the at least one long-duration uplink control signaling, all even-numbered bits are used for transmitting the DMRS.

It should be noted that, in at least two timeslots, each timeslot contains one or two long-duration uplink control signaling, or one long-duration uplink control signaling occupies two or at least two timeslots.

On each long-and-long uplink control signaling, the position of the DMRS is that one DMRS symbol is placed every other symbol, and at this time, the setting of every other symbol may be based on each time slot configuration, or may be based on all time slot configurations. The following is a detailed description by way of examples fourteen and fifteen.

Example fourteen

Embodiment fourteen specifically describes a method of determining DMRS positions in a range of each slot.
