Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numbers in the figures denote elements that have the same or similar functions. While various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.

The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration." Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments.

In addition, in order to better illustrate the present application, numerous specific details are given in the following detailed description. It should be understood by those skilled in the art that the present application may be practiced without certain specific details. In some instances, methods, means, components and circuits well known to those skilled in the art have not been described in detail so as not to obscure the subject matter of the present application.

In order to better understand the technical solutions of the embodiments of the present application, the following technical points are first introduced:

1. About 5G NR

5G NR is a newly proposed topic in the 3rd Generation Partnership Project (3GPP) organization, which is located in Standard 14 (release 14, Rel14). In the past period of time, the Long Term Evolution (Long Term Evolution, LTE) standard proposed by the 3GPP organization has been widely used all over the world, and is called 4G communication technology. For example, China Mobile, China Unicom, and China Telecom have adopted the 4G LTE Frequency Division Duplex (FDD) mode and Time Division Duplex (TDD) mode of transmission technology respectively, and provide users with High-speed and convenient mobile network service.

As the new generation of 5G technology enters the discussion stage, will the system structure and access process that have been achieved in the original 4G LTE continue to be adopted? On the one hand, since the communication system is backward compatible, new technologies developed later tend to be compatible with previously standardized technologies; on the other hand, since 4G LTE already has a large number of existing designs, in order to achieve compatibility, it must be A lot of the flexibility of 5G is sacrificed, which reduces performance. Therefore, currently in the 3GPP organization, two directions are being studied in parallel. Among them, the technical discussion group that does not consider backward compatibility is called 5G NR.

2. About coverage enhancement

In a communication system, there are downlink transmission from network equipment to terminal equipment and uplink transmission from terminal equipment to network equipment. Due to the relatively high cost of network equipment, the coverage of downlink transmission is generally higher than that of uplink transmission. Due to the cost limitation of terminal equipment, only cheaper power amplifiers can be used, and its power upper limit is also lower than that of network equipment. Therefore, the current coverage enhancement research mainly focuses on how to improve the coverage of uplink transmission.

Uplink transmission generally includes PUCCH transmission and PUSCH transmission. Among them, PUCCH belongs to the control channel and has a relatively wide coverage. PUSCH belongs to the data channel, with a large amount of transmission information and relatively close coverage. Therefore, it is more urgent to improve the coverage of PUSCH. question.

3. About PUSCH transmission

In the 5G NR standard, PUSCH transmission can include two transmission modes, also known as mapping modes; one is Type-A, the other is Type-B, and the indication information of each transmission mode includes a start symbol (identified as S), length (identified as L), and the possible value range of S+L, Table 1 shows the PUSCH time domain resource allocation, as shown in Table 1, the symbol S in Table 1 indicates that the start symbol is in a time slot where the value of S starts from 0, that is, the number of the first symbol in a time slot is 0, L represents the length of the PUSCH, that is, the number of symbols occupied by the PUSCH, and S+L represents the start symbol and the PUSCH The range of possible values for the sum of the lengths of .

Table 1-PUSCH time domain resource allocation table

(1) Transmit PUSCH in Type-B mode:

For example, FIG. 1 shows a schematic diagram of transmitting PUSCH in a Type-B manner in the related art. As shown in FIG. 1 , the PUSCH is transmitted in the first time slot and the second time slot, and both the first time slot and the second time slot include 14 symbols, wherein the first time slot includes 6 downlink symbols , 4 idle symbols, and 4 uplink symbols, where the uplink symbol refers to the symbol used for uplink transmission; the downlink signal refers to the symbol used for downlink transmission; the idle symbol, also known as the flexible symbol, or the interval signal, can be located between the uplink signal and the between downstream signals. The second time slot includes at least 10 consecutive upstream symbols, and the upstream symbols of the first time slot are adjacent to the upstream symbols of the second time slot. If S=10, L=14, that is, it starts from the 11th symbol in the first time slot and lasts for 14 symbols. Since the number of symbols in the first time slot is 14, the last 14 symbols are in the above-mentioned 14th symbol. 4 symbols are occupied in one time slot, and 10 symbols are occupied in the second time slot, and these 10 symbols are the 1st symbol to the 10th symbol at the beginning of the second time slot.

In addition, in the transmission of PUSCH in the way of Type-B, the number of PUSCH transmissions can be configured, and the parameter-number of repetitions-r16 is introduced in the 5G NR standard. This parameter has a total of 8 configurable values. , indicated by 3 bits (bit), the configuration values of the above 3 bits correspond to {n1, n2, n3, n4, n7, n8, n12, n16} in turn, where n1 indicates 1 PUSCH transmission, and n16 indicates 16 PUSCH transmissions; The more PUSCH transmission times, the more symbols can be included, and the better the coverage performance. Correspondingly, starting from the symbol of the identifier S of the first time slot, within the symbol range of L*numberOfRepetitions-r16, all available symbols are used for the repeated transmission of PUSCH, that is, a transmission of PUSCH can be made across time slots. , so as to maximize the use of resources.

(2) Transmit PUSCH in Type-A mode:

Different from the above-mentioned Type-B method, which allows one transmission of PUSCH to span time slots, when PUSCH is transmitted in the Type-A method, it can be seen from the above Table 1 that the S+L of Type-A is less than or equal to 14, that is, One transmission of PUSCH is limited to one time slot, and there is no situation that one transmission spans time slots when PUSCH is transmitted in a Type-A manner. Correspondingly, when the PUSCH is configured to transmit PUSCH multiple times in the manner of Type-A, the terminal device will detect each time slot within the range. All L-1 symbols can be used to transmit PUSCH, that is, the symbol identifying S in a certain time slot and the L-1 symbols after the symbol identifying S are not occupied by other transmissions, or the symbol S in a certain time slot is not occupied by other transmissions. The symbol of S and the L-1 symbols after the symbol that identifies S are not downlink symbols, then this transmission of PUSCH can be performed in this time slot, otherwise this transmission of PUSCH in this time slot is abandoned, and the judgment of other times is continued. Whether the gap satisfies the condition.

4. About PUCCH transmission

In the 5G NR standard, the PUCCH transmission method is introduced, and the configuration of PUCCH resources in Radio Resource Control (RRC) includes the following three parameters: the number of slots (Number of Slots, nrofSlots), the number of symbols (Number of Slots) symbols, nrofSymbols), starting symbol index (startingSymbolIndex). Among them, nrofSlots represents the number of configurable repeated transmissions of PUCCH, including 2, 4 or 8 times; nrofSymbols represents the number of symbols occupied by one transmission of PUCCH, and nrofSymbols can be analogous to L in Table 1. In this embodiment of the present application, in order to The abbreviated expression also uses the L mark, that is, L is used to represent the parameter nrofSymbols; startingSymbolIndex represents the number of the PUCCH starting symbol in a time slot, starting from 0, where 0 represents the first symbol in the time slot, and the startingSymbolIndex is the same as that in Table 1 above. The S function is the same.

Among them, the repeated transmission of PUCCH uses the same judgment method as the above-mentioned transmission of PUSCH in the mode of type A, that is, in a time slot, the starting symbol identified by startingSymbolIndex and the starting symbol and the starting symbol after the starting symbol are used. When a total of nrofSymbols symbols can be used to transmit PUCCH, that is, the starting symbol identified by startingSymbolIndex in a certain time slot and the total nrofSymbols symbols including the starting symbol and the following are not occupied by other transmissions, or a certain If the start symbol identified by startingSymbolIndex in the time slot and the nrofSymbols symbols including the start symbol and the following are not downlink symbols, the PUCCH transmission can be performed in this time slot, otherwise, the PUCCH in this time slot is abandoned of this transmission.

For the above-mentioned transmission of PUSCH in Type-B mode proposed in 5G NR Release 16 (Release 16, Rel16), Type-B transmission mode can utilize resources to a greater extent than Type-A transmission mode. The Type-A transmission method can only transmit at a fixed time domain position. If the symbol at the time domain position is unavailable, the transmission is abandoned, while the Type-B transmission method can use all the symbols as much as possible. The PUSCH may be transmitted in symbols. Therefore, many companies consider using the Type-B method to transmit PUCCH, so as to maximize the use of uplink symbols to transmit PUCCH, thereby improving the coverage of PUCCH.

When the PUSCH is being transmitted, a DMRS will be configured on the first symbol. However, in the structure of PUCCH format 3 or format 4, the DMRS is generally configured in the middle of the PUCCH frequency hopping part. Therefore, if the existing Type-B transmission mode is used to transmit PUCCH format 3 or format 4, under certain lengths, the first few symbols (such as the first 3 symbols) of the transmitted PUCCH do not have the relevant configuration of DMRS. If there are only the above-mentioned symbols in the transmission of the PUCCH in this time slot, and there are downlink symbols in the next time slot, this results in that there are no available symbols to carry DMRS in a certain time domain, that is, the above-mentioned symbols do not have corresponding If the DMRS demodulates the channel, there may be a problem that these symbols cannot be decoded.

The following takes the commonly used DDDSU time slot ratio as an example to illustrate the problem that some symbols in the PUCCH using Type-B transmission in the related art do not have a corresponding DMRS demodulation channel, and these symbols may not be decoded. D represents downlink time slot, S represents special time slot, U represents uplink time slot, downlink time slot can include 14 downlink symbols, uplink time slot can include 14 uplink symbols, special time slot is used for downlink to uplink conversion, special The time slot may include 14 symbols, wherein the 14 symbols included in the special time slot may include uplink symbols, downlink symbols and idle symbols. If there is a frequency hopping part of PUCCH without DMRS in a certain uplink time slot, it takes 3 to 4 time slots before the available uplink symbols can be used to transmit PUCCH. With such a long interval, it is difficult for the DMRS before and after. Provides high detection performance.

With reference to Fig. 2, an example is given to illustrate the technical problems existing in the transmission of PUCCH by using Type-B in the related art. Fig. 2 shows a schematic diagram of transmitting PUCCH by Type-B in the related art. As shown in Fig. 2, a special The ratio of time slots is 10:2:2, that is, the special time slot includes 10 downlink symbols, 2 idle symbols and 2 uplink symbols, startingSymbolIndex=12, that is, the starting symbol is the 13th symbol of the special time slot, L=14, that is, the length of one transmission of PUCCH is 14 symbols, the format of the transmitted PUCCH is format 3 or format 4, PUCCH includes two frequency hopping parts, each frequency hopping part occupies 7 uplink symbols, DMRS is configured in On the 4th symbol of each frequency hopping part.

As shown in Figure 2, in one transmission of PUCCH, the 13-14th symbol of the special time slot and the 1-12th symbol of the uplink time slot are occupied. In the next transmission of PUCCH, the uplink time slot is occupied. The remaining two symbols (the two symbols in the circle in Figure 2), that is, the 13th to 14th symbols of the uplink time slot, the DMRS is not configured on the 13th and/or the 14th symbol of the uplink time slot , since the last three time slots adjacent to the uplink time slot are all downlink time slots, the uplink symbol used to transmit the PUCCH will not appear until the next fourth time slot, and the first time slot of the next transmission of the PUCCH will appear. The DMRS is configured on the uplink symbol of the fourth time slot. It can be seen that there is no DMRS for demodulation near the time domain position of the 13th to 14th symbols of the uplink time slot. The problem that the 13-14th symbols in the slot cannot be decoded.

The technical problems existing in the transmission of PUCCH by using Type-B in the related art are illustrated with reference to FIG. 3 . FIG. 3 shows a schematic diagram of transmitting PUCCH in Type-B in the related art. As shown in FIG. 3 , the special The ratio of the time slots is 6:4:4, that is, the special time slot includes 6 downlink symbols, 4 idle symbols and 4 uplink symbols, startsymbolIndex=9, that is, the start symbol is the 10th symbol of the special time slot, L=12, that is, the length of one transmission of PUCCH is 12 symbols, the format of the transmitted PUCCH is format 3 or format 4, PUCCH includes two frequency hopping parts, the first frequency hopping part occupies 1 idle symbol and 5 uplinks symbol, the second frequency hopping part occupies 6 uplink symbols, and the DMRS is configured on the third symbol of each frequency hopping part.

As shown in Figure 3, in one transmission of PUCCH, the 10th to 14th symbols of the special time slot and the 1st to 7th symbols of the uplink time slot are occupied. In the next transmission of PUCCH, the remainder of the uplink time slot is occupied. 7 symbols, that is, the 8-14th symbol of the uplink time slot, wherein the first frequency hopping part of the PUCCH in the next transmission occupies the 8th-13th symbol of the uplink time slot, and the next transmission The second frequency hopping part of the PUCCH occupies the 14th symbol of the uplink time slot (a symbol in the circle in Figure 3), and the DMRS is not configured on the 14th symbol of the uplink time slot; The last three adjacent time slots are all downlink time slots, and the uplink symbol for PUCCH transmission will not appear until the next fourth time slot, and the frequency hopping in the time slot is configured. The first DMRS in the second frequency hopping part is configured on the uplink symbol of the 4th time slot. It can be seen that there is no DMRS for demodulation near the time domain position of the 14th symbol of the uplink time slot. , the problem that the 14th symbol in the uplink time slot cannot be decoded occurs at this time.

With reference to Figure 4, the technical problems existing in the transmission of PUCCH using Type-B in the related art are exemplified. Figure 4 shows a schematic diagram of transmitting PUCCH in Type-B in the related art. The ratio of the time slots is 10:2:2, that is, the special time slot includes 10 downlink symbols, 2 idle symbols and 2 uplink symbols, startsymbolIndex=12, that is, the start symbol is the 13th symbol of the special time slot, L=14, that is, the length of one transmission of PUCCH is 14 symbols, the format of the transmitted PUCCH is format 3 or format 4, and the DMRS is configured on the 4th symbol and the 11th symbol of the PUCCH. In the situation of FIG. 4, No frequency hopping is configured in one transmission of PUCCH, and frequency hopping is configured in the next transmission of PUCCH. In FIG. 4, another frequency hopping mode is different from that in FIG. 2 and FIG. 3. In this frequency hopping mode, Frequency hopping once every 14 symbols is configured to transmit PUCCH.

As shown in Figure 4, in one transmission of PUCCH, the 13th to 14th symbols of the special time slot and the 1st to 12th symbols of the uplink time slot are occupied. In the next transmission of PUCCH, the remainder of the uplink time slot is occupied. The two symbols of (the two symbols in the circle in FIG. 4 ), that is, the 13th-14th symbols of the uplink time slot, and the DMRS is not configured on the 13th and/or the 14th symbol of the uplink time slot; Since the next time slot adjacent to the uplink time slot is a downlink time slot, it can be seen that there is no DMRS near the time domain position where the 13th to 14th symbols of this uplink time slot are located for its demodulation. In the PUCCH configuration, the frequency is hopped once every 14 symbols, that is, the frequency domain position of at least 14 symbols before the 13th to 14th symbols of the uplink time slot is the same as the frequency of the 13th to 14th symbols of the uplink time slot. The domain positions are different. Compared with the scenarios in Figure 2 and Figure 3, the 13th-14th symbols in the uplink time slot in Figure 4 do not even have the previous DMRS to refer to, and the 13th-14th symbols in the uplink time slot at this time symbols are completely undecipherable.

It should be noted that the embodiments of the present application take the DDDSU time slot allocation as an example to illustrate the above-mentioned technical problems existing in the related art using Type-B transmission of PUCCH, and the same or similar problems existing in other time slot allocations It is not repeated; it can be understood that the following technical solutions in the embodiments of the present application can still solve the problem that there is no corresponding DMRS demodulation channel on the part of the symbols where the PUCCH is transmitted in the Type-B manner when other time slot ratios are adopted. , there is a problem that cannot be decoded.

FIG. 6 shows a flowchart of a method for transmitting an uplink control channel according to an embodiment of the present application. The method can be applied to a scenario where PUCCH is transmitted in a Type-B manner. As shown in FIG. 6 , the method may include the following step:

Step 601, the terminal device receives configuration information or indication information from the network device, the configuration information or the indication information is used to configure or instruct the terminal device to send the first PUCCH, the transmission length of the first PUCCH is L symbols, and the number of transmissions of the first PUCCH is is N, N is an integer greater than or equal to 1, and L is an integer greater than or equal to 1;

Optionally, the format of the first PUCCH may be format 3 or format 4, and the value of L is any integer greater than or equal to 4 and less than or equal to 14.

Step 602: The terminal device determines whether to transmit the first PUCCH on X symbols according to a preset condition; the X symbols are located in the first time slot, and the X symbols are used to transmit the first PUCCH.

Exemplarily, when X is less than L, the first PUCCH needs to be transmitted across time slots, and at this time, it can be determined whether to transmit the first PUCCH on X symbols according to a preset condition, so as to avoid the situation that cannot be decoded.

The first time slot may include 14 symbols, and the first time slot may be an uplink time slot, a special time slot, or other time slot including uplink symbols, which is not limited in this embodiment of the present application. Optionally, the terminal device is configured or instructed to transmit the first PUCCH on symbols other than X symbols based on the configuration information or the indication information. After receiving the first PUCCH, the network device may measure the value of the The channel information on the symbol carrying the UCI is then divided by the corresponding channel information measured and obtained by dividing the signal received by the symbol carrying the UCI and decoding, so as to obtain the uplink control information.

It can be understood that the X symbols are used to transmit all the symbols of the first PUCCH in one time slot, and do not include the symbols that carry DRMS; for example, as shown in FIG. 2 above, the X symbols are the 13th symbol of the uplink time slot. and 14th symbols (two symbols shown in circles in Figure 2). For the convenience of description, the definitions of the X symbols referred to in the subsequent embodiments are the same as the definitions of the X symbols in this embodiment.

In the embodiment of the present application, when the terminal device transmits the first PUCCH in X symbols based on the configuration information or the indication information, it can be known that the X symbols do not include symbols carrying DMRS, then the X symbols may have no corresponding DMRS demodulation channel, and there may be In the case of inability to decode, the terminal device determines not to transmit the first PUCCH on X symbols according to a preset condition, thereby avoiding the situation that the X symbols cannot be decoded.

Optionally, the terminal device determines X symbols according to configuration information or indication information; exemplarily, the terminal device may determine X symbols according to the transmission length L of the first PUCCH, the start symbol, and the number of transmissions N. For example, taking the PUCCH transmitted in the above-mentioned FIG. 2 as the first PUCCH, the transmission length of the first PUCCH is L=14, the start symbol is the thirteenth symbol of the special time slot, the number of transmissions is N=2, and the first PUCCH is The first transmission of the first PUCCH occupies the 13-14th symbol in the special time slot and the 1-12th symbol in the uplink time slot, and the first transmission of the first PUCCH occupies the 13th-14th symbol in the uplink time slot and The 12 uplink symbols after the uplink time slot; if the special time slot is taken as the first time slot, then X symbols are the 13th to 14th symbols in the special time slot, and if the uplink time slot is taken as In the first time slot, the X symbols are the 13th to 14th symbols in the uplink time slot.

Optionally, the terminal device may configure the first PUCCH to enable frequency hopping, or not to enable frequency hopping, where the meaning of enabling frequency hopping for the first PUCCH is: according to a predefined manner, the first PUCCH is in the time domain. It is divided into two parts of time domain length, that is, two frequency hopping parts, and each frequency hopping part is transmitted on different frequency domain resources; for example, the time domain length L of the first PUCCH is 14 symbols, when the first PUCCH hops During frequency, the first PUCCH of the 14 symbols will be divided into two frequency hopping parts with a length of 7 symbols, and the two frequency hopping parts with a length of 7 symbols are respectively transmitted in different frequency domain positions . The frequency domain location may be one or more resource blocks (RBs), one or more resource elements (REs), one or more carriers/cells, or One or more bandwidth parts (BWP), which can also be one or more RBs on one or more BWPs on one or more carriers, or one or more RBs on one or more carriers One or more REs on one or more RBs on the BWP.

The technical solution for determining whether to transmit the first PUCCH on X symbols according to a preset condition in step 602 in the embodiment in FIG. 6 will be further described below with reference to the technical solution.

In a possible implementation manner, when the frequency domain position where the X symbols are located is different from the frequency domain position where any DMRS-bearing symbol in the first time slot and the second time slot is located, the terminal device determines that the X symbol is located in the frequency domain position. The first PUCCH is not transmitted; wherein the first time slot is adjacent to the second time slot.

Wherein, the second time slot may be a time slot before the first time slot, or may be a time slot after the first time slot, and may also include both the time slot before the first time slot and the time slot of the first time slot. the next time slot. The previous time slot of the first time slot may include any one of the downlink time slot, the uplink time slot, and the special time slot, and the time slot after the first time slot may include the downlink time slot, the uplink time slot, and the special time slot. For example, the first time slot can be an uplink time slot, the previous time slot adjacent to this one time slot can be a special time slot, and the next time slot adjacent to this one time slot can be a downlink time slot gap.

In the embodiment of the present application, the terminal device knows, according to the configuration information or the indication information, that the X symbols do not include the symbols carrying DMRS, and when the frequency domain positions of the symbols carrying DMRS in the first time slot and the second time slot are the same as the X symbols When the frequency domain positions of the symbols are different, it can be known that within the time domain range of at least one time slot near the X symbols, there is no corresponding DMRS for demodulating the channel, and the terminal equipment determines not to transmit the first PUCCH on the X symbols, so as to avoid the occurrence of The problem that the X symbols cannot be decoded.

Exemplarily, the X symbols are symbols that carry UCI, the first time slot is an uplink time slot, and the frequency domain positions of the other symbols except the X symbols in the uplink time slot where the X symbols are located are the same as the one. The frequency domain positions of the X symbols are different; the previous time slot of the uplink time slot is a special time slot, and the frequency domain positions of the uplink symbols in the special time slot are all different from the frequency domain positions of the X symbols; The next time slot of the uplink time slot is the downlink time slot; at this time, in the uplink time slot where the X symbols are located, the special time slot and the downlink time slot adjacent to the uplink time slot, the frequency where the X symbols are located The domain location does not include DMRS, and the terminal device determines not to transmit the first PUCCH on the X symbol.

For example, the following description will be given by taking a scenario in which the frequency hopping manner in FIG. 4 is configured as frequency hopping once every 14 symbols. FIG. 7 shows a schematic diagram of a method for transmitting an uplink control channel according to an embodiment of the present application; as shown in FIG. 7 , a time slot where the first time slot is located is an uplink time slot, and the last time slot of the uplink time slot is an uplink time slot. The slot is a special time slot, and the next time slot of the uplink time slot is a downlink time slot; wherein, the ratio of the special time slot is 10:2:2, startsymbolIndex=12, L=14, and the first PUCCH of the transmission is The format is format 3 or format 4, and the DMRS is configured in the 4th symbol and the 11th symbol of the first PUCCH transmitted once; the X symbols include the 13th and 14th symbols in the uplink time slot, and the 13th and 14th symbols The 14th symbol is the symbol carrying UCI; the frequency domain positions of the 1-12th symbols in this uplink time slot are different from the frequency domain positions of the 13th and 14th symbols; The uplink symbol is the symbol that carries UCI, and its frequency domain position is different from the 13th and 14th symbols in the uplink time slot; in the special time slot, uplink time slot and downlink time slot in Figure 7, the uplink time slot The 13th and 14th symbols in the frequency domain do not include DMRS. At this time, the 13th and 14th symbols in the uplink time slot do not have corresponding DMRS demodulation channels. The first PUCCH is not transmitted on the 13th and 14th symbols.

In a possible implementation manner, when the interval between the X symbols and the first symbol exceeds a first threshold, the terminal device determines not to transmit the first PUCCH on the X symbols; wherein the first symbol is located in the The first symbol after the X symbols carries the DMRS.

The first threshold may be M time slots, where M is an integer greater than or equal to 1; for example, if M is 2, the first threshold is 2 time slots, and the interval between X symbols and the first symbol In the case of more than 2 time slots, the terminal device determines not to transmit the first PUCCH on X symbols. Exemplarily, when the value of X is greater than or equal to 2, in the case that the interval between any one of the X symbols and the first symbol is more than 2 time slots, or when the last symbol of the X symbols is the same as the first symbol. When the interval between one symbol exceeds 2 time slots, the terminal device determines not to transmit the first PUCCH on X symbols. It can be understood that the first threshold may be predefined or configured by the base station. This embodiment of the present application does not limit the manner of determining the first threshold.

In this embodiment of the present application, the terminal device knows, according to the configuration information or the indication information, that the X symbols do not include symbols carrying DMRS, and when the interval between the X symbols and the first symbol exceeds the first threshold, it can be known that the X symbols are near the first symbol Within the time domain range of the threshold, there is no corresponding DMRS for demodulating the channel, and the terminal device determines not to transmit the first PUCCH on the X symbols, thereby avoiding the problem that the X symbols cannot be decoded.

For example, FIG. 8 shows a schematic diagram of a method for transmitting an uplink control channel according to an embodiment of the present application. As shown in FIG. 8 , the first threshold is set to be 2 time slots, and the first time slot is an uplink time slot , the time slot where the symbol carrying the DMRS is located is a special time slot, wherein the ratio of the special time slot is 6:4:4, L=12, the format of the first PUCCH transmitted is format 3 or format 4, and the first PUCCH is format 3 or format 4. A PUCCH includes two frequency hopping parts, and the DMRS is configured on the 3rd symbol of each frequency hopping part; the X symbols include the 14th symbol of the uplink time slot, and the 14th symbol is a symbol carrying UCI, The next three adjacent time slots of the uplink time slot are all downlink time slots, the fourth time slot is a special time slot, and the 11th symbol of the special time slot is the next symbol that carries the DMRS. At this time, The interval between the 11th symbol of the special time slot and the 14th symbol of the uplink time slot is 3 downlink time slots and 10 symbols, and the interval is greater than 2 time slots. At this time, the 14th symbol of the uplink time slot has no corresponding DMRS demodulation channel, the terminal equipment determines not to transmit the first PUCCH on the 14th symbol in the uplink time slot.

In a possible implementation manner, when X is less than or equal to the second threshold, the terminal device determines not to transmit the first PUCCH on X symbols; wherein the second threshold is based on the length L, the DMRS configuration, the first PUCCH format and at least one of the frequency hopping modes of the first PUCCH is determined.

It can be understood that, the second threshold may be predefined or configured by the base station. This embodiment of the present application does not limit the manner of determining the second threshold.

In this embodiment of the present application, the second threshold may be determined according to at least one of the first PUCCH length L, the DMRS configuration mode, the first PUCCH format, and the frequency hopping mode of the first PUCCH, where the first PUCCH format may include format 3 or format 4, the first PUCCH length L may include lengths corresponding to different formats of the first PUCCH, for example, the length of the first PUCCH format 3 or the length of the first PUCCH format 4; the DMRS configuration mode may include additional DMRS and no additional For DMRS, the frequency hopping manner of the first PUCCH may include frequency hopping within a time slot and no frequency hopping within a time slot.

In this embodiment of the present application, the terminal device knows, according to the configuration information or the indication information, that the X symbols do not include the symbols that carry the DMRS. For the first PUCCH format 3 or the first PUCCH format 4, the DMRS is usually configured in each frequency hopping part of the first PUCCH. In the middle time domain position, it can be known that the X symbols include the first several symbols or the following several symbols in each frequency hopping part of the first PUCCH. When X is less than or equal to the second threshold, the smaller the value of X is, the smaller the value of X is. Therefore, when X is less than or equal to the second threshold, the terminal device determines not to transmit the first PUCCH on X symbols, so as to avoid the occurrence of X symbols A symbol cannot be decoded.

Exemplarily, for the first PUCCH format 3 and the first PUCCH format 4, different first PUCCH lengths in these two formats, two DMRS configuration modes with additional DMRS and no additional DMRS, and two frequency hopping modes are given. The value of the second threshold is shown in Table 2. In Table 2, "PUCCH length" indicates the length value of the first PUCCH format 3 and format 4 different, and the specific value is an integer from 4 to 14; "no additional DMRS" indicates that no additional DMRS is configured in the first PUCCH, and "additional DMRS" indicates that An additional DMRS is configured in the first PUCCH, "No frequency hopping" indicates that frequency hopping is not enabled on the first PUCCH, and "frequency hopping" indicates that frequency hopping is enabled for the first PUCCH. "0" in Table 2 indicates that the second threshold value is 0, which means that the transmission of the first PUCCH does not need to be abandoned.

Table 2 - The second threshold value in the first PUCCH format 3 and format 4

It should be noted that the first PUCCH may enable intra-slot frequency hopping. Therefore, if the lengths of the two frequency hopping parts of the first PUCCH are different, the value of the second threshold may also be different. ” column appears “1, 1” and other values, corresponding to the two frequency hopping parts respectively.

In this embodiment of the present application, the X symbols do not include symbols bearing DMRS, and when the length L of the first PUCCH and the format of the first PUCCH satisfy a certain PUCCH length in Table 2, the second threshold is determined according to the DMRS configuration mode and the frequency hopping mode When the value of X is less than or equal to the second threshold, the X symbols do not have a corresponding DMRS demodulation channel, and the terminal device determines not to transmit the first PUCCH on the X symbols, so as to avoid the occurrence of these X symbols Unable to decode problem.

For example, FIG. 9 shows a schematic diagram of a method for transmitting an uplink control channel according to an embodiment of the present application. As shown in FIG. 9 , L=14, startsymbolIndex=12, and the format of the first PUCCH transmitted is format 3 Or format 4, the first PUCCH enables frequency hopping in the time slot, and the DMRS configuration mode is no additional DMRS; the X symbols include the 13th and 14th symbols of the uplink time slot, that is, the value of X is 2, and the 13th symbol and the 14th symbol are symbols that carry UCI; by looking up Table 2, the value of the second threshold is 3. Since the value of X is less than the second threshold, the terminal equipment determines that the 13th and The first PUCCH is not transmitted over 14 symbols.

In a possible implementation manner, in the above step 603, when the third time slot includes downlink symbols, the terminal device determines not to transmit the first PUCCH on X symbols; wherein the third time slot is the same as the first time slot. The slots are adjacent and after the first slot.

The third time slot may include a downlink time slot or a special time slot, and may also be another time slot including downlink symbols.

In this embodiment of the present application, the terminal device knows, according to the configuration information or the indication information, that the X symbols do not include symbols bearing DMRS, and the downlink symbols are usually configured in the first symbol in the time slot, and when the third time slot includes downlink symbols , for the first PUCCH format 3 or the first PUCCH format 4, the time domain position of the X symbols is usually located at the end of the first time slot. The frequency domain location is different, the symbols adjacent to the X symbols in the third time slot are downlink symbols, then there is no corresponding DMRS in the time domain range of at least one symbol interval near the X symbols that can be used to demodulate the channel. It is determined that the first PUCCH is not transmitted on the X symbols, so as to avoid the problem that the X symbols cannot be decoded.

Optionally, when the downlink symbol is the last one or several symbols in the third time slot, the terminal device determines the number of X symbols and the available symbols in the third time slot according to the number of available symbols in the third time slot before the downlink symbol. Whether the symbol conforms to the first PUCCH length L configured or indicated by the configuration information or the indication information, if so, the first PUCCH can be transmitted on X symbols.

For example, FIG. 10 shows a schematic diagram of a method for transmitting an uplink control channel according to an embodiment of the present application. As shown in FIG. 10 , the ratio of special time slots is 10:2:2, startsymbolIndex=12, L =14, the format of the first PUCCH transmitted is format 3 or format 4, the first PUCCH includes two frequency hopping parts, each frequency hopping part occupies 7 uplink symbols, and the DMRS is configured in the fourth part of each frequency hopping part On the symbol; the first time slot is the uplink time slot, the X symbols include the 13th and 14th symbols in the uplink time slot, and the next time slot of the uplink time slot is the downlink time slot, that is, in the The next time slot includes downlink symbols. At this time, the 13th and 14th symbols in the uplink time slot do not have corresponding DMRS demodulation channels, and the terminal equipment determines that the 13th and 14th symbols in the uplink time slot do not The first PUCCH is transmitted.

In a possible implementation manner, the terminal device may determine, based on the existing PUCCH resource configuration information, not to transmit the first PUCCH on the X symbols.

Wherein, the existing PUCCH resource configuration information may include the PUCCH already configured in the terminal device.

In the embodiment of the present disclosure, it can be applied to a scenario in which X symbols are used based on the existing PUCCH resource configuration information. Using X symbols can improve resource utilization. However, if the value of X is small, the X symbols The PUCCH is configured according to the existing PUCCH resource configuration information. When the configured X symbols do not include symbols carrying DMRS, considering that the existing PUCCH is multiplexed with other terminal equipment, in order to avoid resource waste, the use of X symbols is abandoned. That is, the terminal device does not transmit the first PUCCH on X symbols.

Exemplarily, for the first PUCCH format 3 or the first PUCCH format 4 that has been configured by the terminal device, the DMRS in the first PUCCH is configured in the third symbol, when X=2, if X is used based on the existing PUCCH resource configuration information symbols, then the first two symbols of the first PUCCH are transmitted in X symbols, both of which are symbols that carry UCI, excluding the symbols that carry DMRS. At this time, there is still the possibility of different demodulation of X symbols. Some PUCCHs are multiplexed with other terminal equipments. In order to avoid resource waste, the terminal equipment does not transmit the first PUCCH on X symbols.

Taking FIG. 11 as an example, FIG. 11 shows a schematic diagram of a method for transmitting an uplink control channel according to an embodiment of the present application; as shown in FIG. 11 , the first time slot is a special time slot, and the X symbols include the first time slot. The 13th and 14th symbols of the time slot, and the third time slot is an uplink time slot, wherein the configuration or indication information indicates that the ratio of the first time slot is 10:2:2, startsymbolIndex=12, L=14, in There is a configuration of startsymbolIndex=0, L=14 in the existing RRC configuration of the terminal device, and the format of the first PUCCH transmitted is format 3 or format 4, that is, the first PUCCH has been configured in the 14 symbols in the third time slot. In one transmission of PUCCH, the first PUCCH includes two frequency hopping parts, each frequency hopping part occupies 7 uplink symbols, and the DMRS is configured on the 4th symbol of each frequency hopping part; in this case, since X=2 , the first PUCCH is configured on the 13th and 14th symbols of the first time slot based on the existing PUCCH resource configuration information. Since the DMRS is configured on the fourth symbol of each frequency hopping part of the first PUCCH, at this time, The 13th and 14th symbols of the first time slot are symbols that carry UCI, and do not include symbols that carry DMRS. The 13th and 14th symbols of the first time slot still have the possibility of different demodulation. At the same time, consider The existing PUCCH may be multiplexed with other terminal equipment. In order to avoid resource waste, the terminal equipment does not transmit the first PUCCH in the 13th and 14th symbols of the first time slot.

FIG. 12 shows a flowchart of a method for transmitting an uplink control channel according to an embodiment of the present application. The method can be applied to a scenario of transmitting PUCCH in a Type-B manner. As shown in FIG. 12 , the method may include the following step:

Step 1201, the terminal device receives configuration information or indication information from the network device, the configuration information or the indication information is used to configure or instruct the terminal device to send the first PUCCH, the transmission length of the first PUCCH is L symbols, and the number of transmissions of the first PUCCH is is N, N is an integer greater than or equal to 1, and L is an integer greater than or equal to 1;

Optionally, the first PUCCH may include: UCI and DMRS; the format of the first PUCCH may be format 3 or format 4, and the value of L is any integer greater than or equal to 4 and less than or equal to 14.

Step 1202: The terminal device transmits the first PUCCH on X symbols according to a preset processing method; the X symbols are located in the first time slot, and the X symbols are used for transmitting the first PUCCH.

Exemplarily, when X is less than L, the first PUCCH needs to be transmitted across time slots. In this case, the first PUCCH can be transmitted on X symbols according to a preset processing method, so as to avoid the situation that decoding cannot be performed.

The first time slot may include 14 symbols, and the first time slot may be an uplink time slot, a special time slot, or other time slot including uplink symbols, which is not limited in this embodiment of the present application.

Optionally, the terminal device is configured or instructed to transmit the first PUCCH on symbols other than X symbols based on the configuration information or the indication information. After receiving the first PUCCH, the network device may measure the value of the The channel information on the symbol bearing the UCI is divided by the corresponding channel information measured and obtained by dividing the signal received by the symbol bearing the UCI, and decoding is performed to obtain the UCI.

In the embodiment of the present disclosure, the X symbols do not include the symbols carrying DMRS, the X symbols may have no corresponding DMRS demodulation channel, and the decoding cannot be performed. The terminal device adjusts the frequency domain positions of the X symbols, thereby The situation where these X symbols cannot be decoded is avoided.

The following further describes the technical solution for the terminal device to transmit the first PUCCH on X symbols according to the preset processing method in step 1202 in the embodiment of FIG. 12 .

In a possible implementation manner, the terminal device transmits the first PUCCH on X symbols according to the frequency domain position where the previous frequency hopping part of the X symbols is located; or, the terminal device transmits the first PUCCH according to the frequency domain position where the second symbol is located; , the first PUCCH is transmitted on X symbols; wherein the second symbol is adjacent to the X symbols, or the second symbol and the X symbols are spaced within 14 symbols.

Wherein, the previous frequency hopping part is located before X symbols in the time domain, the last symbol of the previous frequency hopping part is adjacent to X symbols, and the frequency domain position where the previous frequency hopping part is located is the same as the one where the X symbols are located. The frequency domain location is different. For example, taking the above FIG. 2 as an example, in FIG. 2, the X symbol is the 13-14th symbol of the uplink time slot, and the previous frequency hopping part includes the 6th-12th symbol in the uplink time slot.

Wherein, the previous frequency hopping part and the X symbols may be located in the same transmission of the first PUCCH, or may be located in different transmissions of the first PUCCH.

Optionally, the frequency domain position where the previous frequency hopping part is located is different from the frequency domain position where the X symbols are located.

Optionally, the second symbol is adjacent to the X symbols, or the second symbol and the X symbols are spaced within 14 symbols, and the frequency domain position where the second symbol is located is different from the frequency domain location where the X symbols are located.

In the embodiment of the present application, the terminal device transmits the first PUCCH on the X symbols according to the frequency domain position where the previous frequency hopping part of the X symbols is located; thus, the X symbols can multiplex the data transmitted on the previous frequency hopping part. DMRS, to solve the problem that X symbols are missing DMRS, resulting in inability to decode. Or, the terminal device transmits the first PUCCH on X symbols according to the frequency domain position where the second symbol is located; wherein the second symbol is adjacent to the X symbols, or the second symbol and the X symbols are spaced within 14 symbols , at this time, the second symbol can be located in the first few frequency hopping parts of the X symbols. Since the X symbols do not include the symbol carrying the DMRS, the corresponding DMRS is configured in the frequency domain position of the second symbol, so that the X symbols can be Multiplexing the DMRS corresponding to the second symbol solves the problem that X symbols may lack DMRS, resulting in inability to decode.

In a possible implementation manner, the configuration information or the indication information is further used to instruct the terminal device not to enable frequency hopping on X symbols.

It should be noted that if there are Y symbols in a time slot, and the Y symbols are in the time slot, all symbols used to transmit the first PUCCH, the Y symbols do not include the symbols carrying DMRS, but, In the next time slot or the previous time slot, Y symbols have corresponding DMRS demodulation, which do not belong to the X symbols in this implementation manner. As shown in Figure 4 above, in Figure 4, the Y symbols are the 13th and 14th symbols of the special time slot (the two symbols shown in the circle in Figure 4), since these two symbols are in the next time slot The DMRS on the 2nd symbol of is demodulated, so these Y symbols do not belong to the X symbols in this implementation.

The above-mentioned terminal device transmitting the first PUCCH on X symbols according to the frequency domain position of the previous frequency hopping part of the X symbols may include: the terminal device does not enable frequency hopping on the X symbols. Among them, "disable frequency hopping" can be understood that the terminal equipment is configured with frequency hopping, but does not perform the frequency hopping.

In this embodiment of the present application, if the terminal device enables frequency hopping on X symbols and sends the first PUCCH on the X symbols, in this case, the terminal device sends the first PUCCH on the X symbols, and the network After the device receives the first PUCCH in the X symbols, since the X symbols do not include the symbols carrying the DMRS, the network device cannot use the DMRS to demodulate the first PUCCH, resulting in the problem of inability to decode. At this time, the terminal device according to the configuration information Or the indication information does not enable frequency hopping on these X symbols, so that the frequency domain position of the X symbols is the same as the frequency domain position of the previous frequency hopping part of the X symbols, so that the X symbols can be multiplexed with the previous one. The DMRS transmitted on the frequency hopping part avoids the problem that the X symbols cannot be decoded.

Wherein, the previous frequency hopping part of the X symbols may be located in the same transmission of the first PUCCH as the X symbols, or may not be located in the same transmission of the first PUCCH.

Exemplarily, the X symbols are symbols that carry UCI, the first time slot is an uplink time slot, the previous frequency hopping part of the X symbols is located in the uplink time slot, and the previous frequency hopping part and the X symbols are Not located in the first PUCCH of the same transmission, the previous frequency hopping part includes a symbol carrying DMRS, and at the same time, the next symbol adjacent to the X symbols is a downlink symbol. At this time, the X symbols do not have corresponding symbols. The DMRS demodulates the channel, the terminal equipment does not enable frequency hopping on these X symbols, so that the X symbols are in the same frequency domain position as the previous frequency hopping part, so that the X symbols in the uplink time slot can be repeated. The DMRS transmitted on the previous frequency hopping part in the uplink time slot is used to avoid the problem that the X symbols in the uplink time slot cannot be decoded.

For example, FIG. 13 shows a schematic diagram of a method for transmitting an uplink control channel according to an embodiment of the present application; as shown in FIG. 13 , the first time slot is an uplink time slot, and the previous time slot of the uplink time slot is is a special time slot, and the next symbol adjacent to the X symbols is a downlink symbol; wherein, the ratio of the special time slot is 10:2:2, startsymbolIndex=12, L=14, the format of the first PUCCH transmitted For format 3 or format 4, the first PUCCH includes two frequency hopping parts, each frequency hopping part occupies 7 uplink symbols, and the DMRS is configured on the 4th symbol of each frequency hopping part; when X symbols include the uplink The 13th and 14th symbols in the slot (the symbols in the circles in Figure 13), and the 13th and 14th symbols are symbols that carry UCI; the previous frequency hopping part of X symbols is related to the 13th and 14th The symbol is not located in the first PUCCH of the same transmission; the previous frequency hopping part includes the 6th to 12th symbols in the uplink time slot, and the 9th symbol in the uplink time slot is the symbol carrying the DMRS; this When there is no corresponding DMRS demodulation channel for the 13th and 14th symbols in the uplink time slot, the terminal equipment does not enable frequency hopping on the 13th and 14th symbols in the uplink time slot, so that in the uplink time slot The 13th and 14th symbols are in the same frequency domain position as the 6th to 12th symbols in the upstream time slot, so that the 13th and 14th symbols in the upstream time slot can be multiplexed with the 9th symbol in the upstream time slot. DMRS for symbol transmission.

The following describes a scenario where there are two or more frequency hopping positions configured in the first time slot, and the terminal device does not enable frequency hopping on X symbols.

It should be noted that if there are Y symbols in a time slot, and the Y symbols are in the time slot, all symbols used to transmit the first PUCCH, the Y symbols do not include the symbols carrying DMRS, but, In the next time slot or the previous time slot, if Y symbols have corresponding DMRS demodulation, they do not belong to X symbols in this scenario. As shown in Figure 4 above, in Figure 4, the Y symbols are the 13th and 14th symbols of the special time slot (the two symbols shown in the circle in Figure 4), since these two symbols are in the next time slot The DMRS on the 2nd symbol of is demodulated, so these Y symbols do not belong to the X symbols in this implementation. In this scenario, in a time slot, there are at least 2 frequency hopping positions, and the format of the first PUCCH is format 3 or format 4. The terminal device indicates the first PUCCH length L, starting position, transmission The number of times N is to transmit the first PUCCH. Because in the first PUCCH format3 or format4, the DMRS is usually configured in the middle of the frequency hopping part. For some L values, the first 3 symbols of each frequency hopping part may exist without DMRS. Related configuration, at this time, the first PUCCH is transmitted in X symbols. Since X symbols do not include symbols bearing DMRS, the next symbol bearing DMRS may be located after multiple downlink time slots. In the case of equal to 2 frequency hopping positions, the frequency domain position where the X symbols are located does not even have DMRS, and the X symbols do not have a corresponding DMRS demodulation channel; in this case, the terminal device determines that the X symbols do not include The symbol carrying the DMRS, the terminal equipment does not enable frequency hopping on these X symbols, so that the frequency domain position of the X symbols is the same as the frequency domain position of the previous frequency hopping part of the X symbols, so that the X symbols The DMRS transmitted on the previous frequency hopping part can be multiplexed to avoid the problem that the X symbols cannot be decoded; and the DMRS of the previous frequency hopping part can be utilized to the maximum extent to improve the decoding effect.

Exemplarily, the X symbols are symbols that carry UCI, the first time slot is an uplink time slot, at least two frequency hopping positions are configured in the uplink time slot, and the frequency domain positions where the X symbols are located are the same as the uplink time slot. The frequency domain positions of other symbols in the slot are different, the previous frequency hopping part of the X symbols is located in the uplink time slot, and the previous frequency hopping part and the X symbols are not located in the first PUCCH of the same transmission, The previous frequency hopping part includes a symbol carrying DMRS, and at the same time, the next symbol adjacent to the X symbols is a downlink symbol. At this time, the X symbols do not have a corresponding DMRS demodulation channel, and the terminal equipment is in the X symbols. The frequency hopping is not enabled on the symbol, so that the X symbols are in the same frequency domain position as the previous frequency hopping part, so that the X symbols in the uplink time slot can reuse the previous frequency hopping in the uplink time slot. Part of the DMRS transmitted on the uplink, thereby avoiding the problem that the X symbols in the uplink time slot cannot be decoded, and maximizing the use of the DMRS-bearing symbols in the previous frequency hopping part to improve the decoding effect.

For example, FIG. 14 shows a schematic diagram of a method for transmitting an uplink control channel according to an embodiment of the present application; as shown in FIG. 14 , in a scenario where three frequency hopping positions are configured in one time slot, the first The time slot is an uplink time slot, the previous time slot of the uplink time slot is a special time slot, and the next symbol adjacent to the X symbols is a downlink symbol; wherein, the special time slot ratio is 10:2:2, startsymbolIndex=12, L=14, the format of the first PUCCH transmitted is format3 or format4, the first PUCCH includes two frequency hopping parts, each frequency hopping part occupies 7 uplink symbols, and the DMRS is configured in each frequency hopping part On the 4th symbol; 3 frequency hopping positions are configured in the uplink time slot, which are respectively located in the 6th symbol and the 13th symbol of the uplink time slot, and the 1st to 5th symbols in the uplink time slot are located The frequency domain positions of the 6th to 12th symbols in the uplink time slot are different from each other, and the frequency domain positions of the 13th and 14th symbols in the uplink time slot are different from each other; X symbols include the uplink time slot. The 13th and 14th symbols in the time slot, and the 13th and 14th symbols are symbols that carry UCI; the previous frequency hopping part of X symbols and the 13th and 14th symbols are not located in the same transmission. In the first PUCCH; the previous frequency hopping part includes the 6th to 12th symbols in the uplink time slot, and the 9th symbol in the uplink time slot is a symbol that carries DMRS; at this time, in the uplink time slot The 13th and 14th symbols do not have corresponding DMRS demodulation channels, and the terminal device does not enable frequency hopping on the 13th and 14th symbols in the uplink time slot, so that the 13th and 14th symbols in the uplink time slot The same frequency domain positions as the 6th to 12th symbols in the uplink time slot are located, so that the 13th and 14th symbols in the uplink time slot can multiplex the DMRS transmitted by the ninth symbol in the uplink time slot.

For example, FIG. 15 shows a schematic diagram of a method for transmitting an uplink control channel according to an embodiment of the present application; as shown in FIG. 15 , it is a scenario in which two frequency hopping positions are configured in one time slot, and X The first time slot where the symbol is located is an uplink time slot, the previous time slot of this uplink time slot is a special time slot, and the next time slot of this uplink time slot is a downlink time slot; among them, the ratio of special time slots is 10 :2:2, startsymbolIndex=12, L=14, the format of the first PUCCH transmitted is format 3 or format 4, and the DMRS is configured on the 4th symbol and the 11th symbol of the first PUCCH transmitted once; X symbols Including the 13th and 14th symbols in the uplink time slot, and the 13th and 14th symbols are symbols that carry UCI; the frequency domain positions of the 13th and 12th symbols in the uplink time slot are the same as the 13th and 14th symbols. The positions of the 14th symbol in the frequency domain are different; the two uplink symbols in this special time slot are symbols that carry UCI, and their frequency domain positions are different from the 13th and 14th symbols in the uplink time slot; in Fig. In the special time slot, uplink time slot and downlink time slot in 15, the frequency domain positions of the 13th and 14th symbols in the uplink time slot do not include DMRS. At this time, the 13th and 14th symbols in the uplink time slot There is no corresponding DMRS demodulation channel for each symbol, and the terminal equipment does not enable frequency hopping on the 13th and 14th symbols in the uplink time slot, so that the 13th and 14th symbols in the uplink time slot are the same as those in the uplink time slot. The positions of the 6th to 12th symbols in the frequency domain are the same, so that the 13th and 14th symbols in the uplink time slot can multiplex the DMRS transmitted by the ninth symbol in the uplink time slot.

In a possible implementation manner, the configuration information or the indication information is further used to instruct the terminal device to adjust the frequency domain position of the frequency hopping part where the X symbols are located to be the same as the frequency domain position of the previous frequency hopping part of the X symbols, And the frequency domain position of the next frequency hopping part of the X symbols is adjusted to be the same as the frequency domain position of the X symbols.

The above-mentioned terminal equipment transmits the first PUCCH on the X symbols according to the frequency domain position where the previous frequency hopping part of the X symbols is located, including: the terminal equipment adjusts the frequency domain position of the frequency hopping part where the X symbols are located to The frequency domain position of the previous frequency hopping part of the symbol is the same, and the frequency domain position of the next frequency hopping part of X symbols is adjusted to be the same as the frequency domain position of X symbols.

Optionally, the frequency hopping part and the next frequency hopping part where the X symbols are located both contain one DMRS-bearing symbol or both contain two DMRS-bearing symbols, or, the frequency hopping part and the next frequency hopping part where the X symbols are located may be. One hopping part contains one DMRS-carrying symbol, and the other hopping part contains two DMRS-carrying symbols.

Exemplarily, the frequency domain position of the frequency hopping part where the X symbols are located may be denoted as the first frequency domain position, and the frequency domain position of the next frequency hopping part of the X symbols may be denoted as the second frequency domain position; In the first PUCCH of a transmission where the symbol is located, when a symbol is configured in the first frequency domain position, the terminal device adjusts the frequency domain position of the symbol to the second frequency domain position; when a symbol is configured in the second frequency domain position When , the terminal device adjusts the frequency domain position of the symbol to the first frequency domain position.

Optionally, the X symbols are the last X symbols in a time slot. For example, X=2, the last 2 symbols in the first slot.

In the embodiment of the present application, the X symbols do not include symbols that carry DMRS. It can be seen from the above statement that there is a problem that the X symbols may lack DMRS, resulting in inability to decode. Therefore, the terminal device adjusts the first transmission where the X symbols are located. The frequency domain position of each symbol of a PUCCH, the frequency domain position of the frequency hopping part where the X symbols are located is adjusted to be the same as the frequency domain position of the previous frequency hopping part of the X symbols, and the next frequency hopping part of the X symbols is adjusted. The frequency domain position of the X symbols is adjusted to be the same as the frequency domain position of the X symbols; so that the frequency domain position of the X symbols is the same as the frequency domain position of the previous frequency hopping part of the X symbols, so that the X symbols can be multiplexed before. DMRS transmitted on a frequency hopping part, so as to avoid the problem that the X symbols cannot be decoded.

Wherein, when frequency hopping is enabled for the first PUCCH, and the first PUCCH transmitted at one time includes two frequency hopping parts, that is, the first frequency hopping part and the second frequency hopping part, the first frequency domain position may refer to the first frequency domain position of the first PUCCH. The frequency domain location where the first frequency hopping part is located, and the second frequency domain location may refer to the frequency domain location where the second frequency hopping part of the first PUCCH is located.

Exemplarily, the first PUCCH transmitted at one time includes two frequency hopping parts, the frequency domain position where the previous frequency hopping part is located is denoted as the first frequency domain position, and the frequency domain position where the latter frequency hopping part is located is denoted as the first frequency domain position.

A frequency hopping part and X symbols are not located in the first PUCCH of the same transmission, the previous frequency hopping part includes a symbol bearing DMRS, and the frequency domain position where the previous frequency hopping part is located is the second frequency domain position; At this time, the X symbols do not have a corresponding DMRS demodulation channel, and the terminal device adjusts the frequency domain positions of the first PUCCH symbols of the one transmission where the X symbols are located. The symbol configured in the second frequency domain position in the first PUCCH is adjusted to the first frequency domain position, and the terminal device adjusts the symbol configured in the first frequency domain position in the first PUCCH where X symbols are located to the second frequency domain position. domain position; wherein, the terminal equipment adjusts the frequency domain position where the X symbols are located from the first frequency domain position to the second frequency domain position; so that the frequency domain position of the X symbols is the same as that of the previous frequency hopping part of the X symbols The frequency domain positions are the same, so that the X symbols can multiplex the DMRS transmitted on the previous frequency hopping part, thereby avoiding the problem that the X symbols cannot be decoded.

Step 1901: The terminal device receives configuration information or indication information from the network device, the configuration information or indication information is used to configure or instruct the terminal device to send the first PUCCH, the transmission length of the first PUCCH is L symbols, and the number of transmissions of the first PUCCH is is N, where N is an integer greater than or equal to 1, and L is an integer greater than or equal to 1.

Step 1902: The terminal device transmits the DMRS on X symbols according to the preset processing mode; the X symbols are located in the first time slot, and the X symbols are used to transmit the first PUCCH.

Exemplarily, when X is less than L, the first PUCCH needs to be transmitted across time slots, and at this time, according to a preset processing method, the DMRS is transmitted on X symbols, so as to avoid a situation that cannot be decoded. The first time slot may include 14 symbols, and the first time slot may be an uplink time slot, a special time slot, or other time slot including uplink symbols, which is not limited in this embodiment of the present application.

In an exemplary embodiment: if there is no DMRS on the frequency hopping part of the time slot, and the next time slot is a downlink time slot, the terminal device abandons the transmission of part of the symbols;

Core idea: The PUCCH symbol at one frequency domain position in the time slot only has the symbol carrying UCI, no DMRS, and the next time slot is a downlink time slot, and the terminal equipment abandons the transmission of the above symbols.

Judgment condition 1: Among the available symbols in a time slot, there is only a symbol carrying UCI in a frequency domain position, and there is no DMRS symbol, and there is no DMRS in the frequency domain position in the previous time slot and the next time slot.

Judgment condition 2: The interval between the frequency hopping part without DMRS and the next available symbol carrying DMRS exceeds X time slots, and X is greater than or equal to 1.

Judgment Condition 3: Define dropping length, as shown in Table 2 above, for PUCCH in PUCCH format 3/4, the number of symbols with different PUCCH lengths and with or without additional DMRS is given. , when the transmitted PUCCH satisfies the PUCCH length (PUCCH length), and the remaining symbols in a certain frequency hopping position in a time slot are less than or equal to the abandonment length in Table 2, the frequency domain position does not transmit PUCCH. In particular, PUCCH may enable intra-slot frequency hopping, that is, "frequency hopping" in Table 2. Therefore, if the lengths of the two frequency hopping parts are different, the abandonment lengths may also be different, so that "frequency hopping" appears in the "frequency hopping" column. 1, 1" two values, corresponding to two frequency hopping parts respectively. In addition, "0" in Table 2 represents that the length is not abandoned, that is, the transmission of the PUCCH does not need to be abandoned.

For example, as shown in Figure 9 above, L=14, startingSymbolIndex=12, the last two symbols in the time slot in Figure 9 do not have DMRS, and Table 2 can be consulted to obtain the abandonment length of 3 symbols, so the last two symbols above Abandon the transfer.

In this embodiment, the proposed judgment condition for abandoning part of PUCCH transmission in Type-B transmission PUCCH effectively avoids the problem of no DMRS.

In another exemplary embodiment: if there is no DMRS on the frequency hopping portion of the time slot, the terminal device does not enable current location frequency hopping;

Core idea: If there is no DMRS on the frequency hopping part in the time slot, the frequency hopping at the current location is not enabled or the frequency domain location is exchanged.

In an implementation manner, the terminal equipment does not enable frequency hopping: as shown in Figure 13 above, when it is judged that there is no DMRS on a frequency hopping part, the terminal equipment makes the frequency hopping by not enabling the frequency hopping of the frequency hopping part. The last frequency hopping part and the previous frequency hopping part may be located in the same PUCCH transmission, or may not be the same PUCCH transmission.

In another implementation manner, the terminal equipment switches the frequency domain: the two frequency domain positions of each PUCCH transmission are switched, as shown in the above FIG. Frequency hopping transmission at each frequency domain position, and frequency hopping transmission at two frequency domain positions pos2 and pos1 respectively in the k+1th time, so that the last two symbols in the previous time slot have no DMRS in the time slot. Use the DMRS of the remaining frequency hopping parts at the same frequency domain location.

The solution proposed in this embodiment enables symbols without DMRS to multiplex previously transmitted DMRS symbols, thereby solving the problem of lack of DMRS.

In another exemplary embodiment: the terminal device places the DMRS on the frequency hopping portion of the time slot without the DMRS;

The core idea is to place the DMRS on the frequency hopping part without DMRS in the time slot. The effect of this is that the channel measurement performance of the DMRS can be jointly enhanced with the DMRS on the previous frequency hopping part.

According to the time slot configuration, there is no DMRS in the frequency hopping part of the PUCCH, so that the frequency hopping part may not be able to be demodulated. It is a method to enhance transmission performance.

In one implementation, the DMRS is transmitted on this part, and if at least one symbol appears, the at least one DMRS is also located in the same frequency domain position, as shown in (b) of the above-mentioned FIG. 20 .

In another implementation manner, if intra-slot hopping is configured on the PUCCH, that is, frequency hopping within the slot, in the case of N symbols (N>1), the DMRS is transmitted according to frequency hopping, and the first DMRS part contains

symbols, the second DMRS part contains

symbols, as shown in Figure 21 above.

The technical solution of this embodiment can solve the problem of missing DMRS in the frequency hopping part when Type-B transmits PUCCH, and at the same time effectively use these symbols to carry DMRS, enhance the detection performance of DMRS, and thus improve the coverage.

In another exemplary embodiment: the frequency hopping part without DMRS in the time slot is the same as the frequency domain position of the previous frequency hopping part, so as to reuse the DMRS of the previous frequency hopping part; if more than 2 frequency hopping positions are configured In the case of hopping position, the next DMRS may be located after multiple downlink time slots, so the decoding effect of the remaining symbols placed in the previous frequency hopping part is better.

The core idea is that the frequency hopping part without DMRS in the time slot has the same frequency domain position as the previous frequency hopping part, so that the DMRS of the previous frequency hopping part is used for demodulation.

For the case where more than or equal to 2 frequency hopping positions hopping positions are configured, the next DMRS may be located after multiple downlink time slots, and even the frequency domain positions where these symbols are located have no DMRS, as shown in "Update frequency domain position" in Figure 14 above. "The situation shown earlier.

At this time, in view of this situation, the remaining symbols are configured to be placed in the same frequency domain position of the previous frequency hopping part, so as to maximize the use of the DMRS of the previous frequency hopping part, thereby improving the decoding effect, that is, for frequency hopping in the time slot In the case of partial and no DMRS, the frequency domain position is updated to the last frequency hopping position, as shown after "Update frequency domain position" in Figure 14 above.

The technical solution of this embodiment updates the frequency domain positions of these symbols, so that the previously transmitted DMRS can be multiplexed; the problem of missing DMRS in the frequency hopping part when Type-B transmits PUCCH can be solved.

In another exemplary embodiment: based on the multiplexing structure of the legacy terminal equipment (legacy UE), the location and content of the additional transmission symbols are determined; wherein,

When the number of symbols is greater than or equal to 4, an additional L' length of PUCCH format3/4 can be transmitted.

If the number of symbols is too small to provide DMRS symbols within L lengths, these symbols are discarded.

Optionally, the number of symbols is less, and the added symbols are used as extra DMRS or L-truncated symbols.

Core idea: Determine the location and content of additional transmission symbols based on the existing PUCCH resource configuration information, and indicate additional transmission PUCCH transmission resources through indication information.

An implementation method: an L' length of PUCCH format 3/4 transmission can be added; optionally, the number of available symbols is greater than or equal to 4; among them, the frequency hopping of L' length can be selected whether to use the frequency hopping configured by RRC. Specifically, configure an additional PUCCH resource set additional PUCCH resource set in PUCCH-config, which can be matched with the existing resource set resource set. For example, a resource startingSymbolIndex in the existing resource set is 0 and the length is 14, then consider In the configuration of S slot=6:4:4, the startingSymbolIndex of a resource in the additional PUCCH resrouce set is 10 and the length is 4. During specific scheduling, when PDSCH transmission is indicated by DCI, resources in the additional PUCCH resource set are additionally indicated, and the terminal device uses the PUCCH resources in the two resource sets (may include the number of repetitions, etc.).

For example, as shown in Figure 25 above, S slot=6:4:4, startingSymbolIndex=10, there is a configuration of L=14 in the existing RRC configuration, and L'=4 is obtained; then configure the PUCCH corresponding to L' , may use frequency hopping (as shown in Figure 25 (a)) or may not use frequency hopping transmission (as shown in Figure 25 (b)).

Another implementation manner: the number of symbols is small, and the DMRS symbols within the length of L are insufficient to provide, and the terminal equipment abandons the PUCCH transmission on the corresponding symbols.

As shown in Figure 11 above, S slot=10:2:2, startingSymbolIndex=13, and there is a startingSymbolIndex=0, L=14 configuration in the existing RRC configuration. At this time, considering that the existing PUCCH has connections with other terminals For device multiplexing, in order to avoid resource waste, PUCCH transmission with startingSymbolIndex=13 is abandoned.

Another implementation manner: the added extra symbols are used as additional DMRS or L-truncated symbols; the above-mentioned L-truncated PUCCH or extra DMRS may cross the slot boundary.

Optionally, when the extra symbol is used to carry DMRS and frequency hopping, the first DMRS part contains

symbols, the second DMRS part contains

symbol.

For example, as shown in Fig. 18 and Fig. 23 above, L* in Fig. 18 means L truncation, adding DMRS in Fig. 23 means L truncation, S slot=6:4:4, startsymbolIndex=10, existing There is a configuration of startingSymbolIndex=2, L=12 in the RRC configuration. At this time, there are 4 symbols left in the S slot, and the first two symbols are left in the next time slot. The PUCCH transmission of L=12 can be configured, but only 6 symbols are occupied. That is, the L-truncated PUCCH is shown in FIG. 18 above. Another possible situation is to add additional DMRS to the above 6 symbols. If frequency hopping is not used, the above 6 symbols are located in the same frequency domain position. If frequency hopping is enabled, the first DMRS part contains

symbols, the second DMRS part contains

symbols, as shown in Figure 23 above.

For another example: as shown in Figure 17 and Figure 22 above, S slot=6:4:4, startsymbolIndex=10, and there is a configuration of startsymbolIndex=0, L=14 in the existing RRC configuration.

The technical solution of this embodiment can solve the problem of missing DMRS in the frequency hopping part when Type-B transmits PUCCH; at the same time, additional PUCCH resources are scheduled based on the existing PUCCH configuration, so that the PUCCH multiplexing in the existing configuration is not affected, and the improved Frequency domain resource utilization.
