Specifically, when the information transmission referred to in the present application is uplink transmission of information, the transmitted information may be UCI, or may also be traffic data (that is, a Protocol Data Unit (PDU) that is delivered by a Media Access Control (MAC) layer to a physical layer), and the used physical channel may be a PUCCH or a Physical Uplink Shared Channel (PUSCH), which is not limited herein. Wherein, the PUSCH may also carry UCI. When the information transmission referred to in the present application is downlink transmission of information, the transmitted information may be service data, and the used physical channel may be a Physical Downlink Shared Channel (PDSCH), and the like, which is not limited herein.

The priority of the service data may be a priority of a logical channel, that is, a priority of a logical channel corresponding to data carried in the PDU, and may be a highest priority among the plurality of logical channels.

The priority of the UCI may be related to information included in the UCI, a physical uplink channel carrying the UCI, a cell, periodicity, and other factors. Utensil for cleaning buttockThe CSI is used as an example for the description. Each CSI report (CSI report) may define a priority value (priority value), pri _iCSI (y,k,c,s)＝2·N _cells ·M _S ·y+N _cells ·M _S ·k+M _S The smaller the value of c + s, the higher the priority. Wherein y =0 when aperiodic (aperiodic) CSI reporting is carried on PUSCH, and y =1 when semi-persistent (semi-persistent) CSI reporting is carried on PUSCH. When semi-static (semi-persistent) CSI reporting is carried on PUCCH, y =2, and when periodic (periodic) CSI reporting is carried on PUCCH, y =3. K =0 if the CSI comprises RSRP or SINR, otherwise k =1.c is the serving cell index, N _cells Is the number of cells, s is the index of the reporting configuration, M _S The maximum value of the number of CSI reporting configurations.

The priority of UCI may also be configured by higher layer signaling or indicated by Downlink Control Information (DCI). For example, when DCI schedules HARQ-ACK, the priority of HARQ-ACK may be indicated. Indicating whether the HARQ-ACK is high priority or low priority if there are only two priorities.

The priority of UCI may also be traffic related, e.g., UCI for mtc is a low priority relative to eMBB UCI. In addition, UCI between different PUCCH groups may also define a priority, for example, UCI in PUCCH group 0 has a higher priority than UCI in PUCCH group 1. Or UCI between different base stations, or UCI between different UEs, or UCI between different Transmission Reception Points (TRPs), or priority between them may also be defined.

When the UCI with high and low priorities is multiplexed, the UCI with High Priority (HP) and UCI with Low Priority (LP) are carried on PUCCH or PUSCH. For example, HP HARQ-ACK, LP HARQ-ACK and HP SR are carried on PUCCH. High priority HARQ-ACK, low priority HARQ-ACK, and HP or LP CSI are carried on the PUSCH.

For convenience of description, the following embodiments of the present application are all described by taking UCI transmission as an example. When UCI of different priorities are multiplexed together and transmitted through one PUCCH, the following two cases mainly exist:

case 1: high Priority (HP) UCI (hereinafter referred to as HP UCI) is 1 bit, low Priority (LP) UCI (hereinafter referred to as LP UCI) is 1 bit, and after multiplexing together, 2 bits are obtained, which can be transmitted through PUCCH format 1. The modulation mapping method may be QPSK modulation. However, since the reliability requirement of HP UCI is higher, the performance of HP UCI is affected by QPSK because the distances between constellation points between QPSK are all the same.

Case 2: the UCI with high priority is 1 bit, the UCI with low priority is 2 bits, the UCI is 3 bits after multiplexing, and the UCI is transmitted through PUCCH format 2/3/4. Because the reliability requirement of HP UCI is higher than that of LP UCI, if a coding mode of 1-bit UCI on PUSCH is used, bit scrambling may need to be modified, the protocol impact is large, and UE implementation is complex.

Based on this, how to improve the transmission reliability of high-priority information (e.g., UCI) becomes one of the problems to be solved at present.

The technical solutions provided in the present application will be described in detail below with reference to more drawings.

Referring to fig. 3 for case 1, fig. 3 is a flow chart of an information transmission method according to an embodiment of the present disclosure. The method can be applied to terminal equipment or access network equipment. As shown in fig. 3, the method includes the following steps S301 to S303:

s301, determining a first parameter value according to the bit value of the first information, and determining a second parameter value according to the bit value of the second information.

In some possible embodiments, the terminal device or the access network device may determine the first parameter value according to a bit value of the first information and determine the second parameter value according to a bit value of the second information. The absolute value of the first parameter value is larger than that of the second parameter value, and the priority of the first information is higher than that of the second information. It should be understood that, when the terminal device determines the first parameter value according to the bit value of the first information and determines the second parameter value according to the bit value of the second information, the first information and the second information may be UCI, or the first information and the second information may also be service data, and the like, which is not limited herein. When the access network device determines the first parameter value according to the bit value of the first information and determines the second parameter value according to the bit value of the second information, the first information and the second information may be service data, and the like, which is not limited herein.

In general, when the first information and the second information are UCI, the first information and the second information may be hybrid automatic repeat request acknowledgement (HARQ-ACK), channel State Information (CSI), scheduling Request (SR), or the like, which is not limited herein. When the first information and the second information are UCI, the first information may also be different from the second information, for example, the first information is HARQ-ACK, the second information is CSI, and the like, which is not limited herein. If the first information and the second information are service data, the first information and the second information may be video data, voice data, text data, and the like, and may also be a protocol data unit PDU that the MAC delivers to the physical layer, which is not limited herein. The first information may also be UCI and the second information is traffic data. Or, the first information is service data and the second information is UCI.

It can be understood that, in the embodiment of the present application, when the first information and the second information are UCI, the transmission of the related information is uplink transmission of the information (that is, the terminal device sends the first information and the second information to the access network device). When the first information and the second information are service data, the transmission of the information may be uplink transmission of the information, or may also be downlink transmission of the information (that is, the access network device sends the first information and the second information to the terminal device), which is not limited herein. The physical channel related to uplink transmission may be a PUCCH or a PUSCH, and the physical channel related to downlink transmission may be a PDSCH, etc., without limitation. For convenience of understanding, the following embodiments of the present application all use the first information and the second information as UCI, and the physical channel is PUCCH as an example for explanation. When the length of each of the bit sequence of the first information and the bit sequence of the second information is 1 bit, the PUCCH format 1 may be the PUCCH format. That is, the first information and the second information may be simultaneously carried through PUCCH format 1. Wherein, the absolute value of the first parameter value being greater than the absolute value of the second parameter value can be understood as: when the information is transmitted through the PUCCH format 1, the first information and the second information are mapped to a physical channel through a mapping mode with unequal intervals, and the performance of the first information can be improved.

S302, determining a modulation symbol according to the first parameter value and the second parameter value.

In some possible embodiments, a modulation symbol may be determined from the first parameter value and the second parameter value, where the modulation symbol satisfies: d (i) = M × { x (i) + j × y (i) } or d (i) = M × { y (i) + j × x (i) }. Wherein d (i) is a modulation symbol, x (i) is a first parameter value, y (i) is a second parameter value, i is an index of the modulation symbol, j is an imaginary unit, and M is a preset value. Specifically, the first parameter value and the second parameter value may satisfy:

x(i)＝(1-2b(2i))×3；

y(i)＝1-2b(2i+1)；

where b (2 i) is the bit value of the first information and b (2i + 1) is the bit value of the second information.

Optionally, the first parameter value and the second parameter value may further satisfy:

x(i)＝(1-2b(2i+1))×3；

y(i)＝1-2b(2i)；

where b (2i + 1) is the bit value of the first information, and b (2 i) is the bit value of the second information.

Wherein, the preset value can satisfy:

that is, when the PUCCH is PUCCH format 1 and 1-bit HP UCI and 1-bit LP UCI are carried on PUCCH format 1, 4 points may be selected for modulation in a constellation of quadrature amplitude modulation (16 QAM). Referring to fig. 4, fig. 4 is a schematic diagram of a constellation diagram of 16QAM modulation provided in an embodiment of the present application. As shown in fig. 4, the point shown in graph 1 in the constellation diagram of 16QAM can be selected for modulation, or alternatively, the point shown in graph 2 can be selectedThe point of (2) is modulated. Wherein, the distance between the HP UCI =0 and the HP UCI =1 is greater than the distance between the HP UCI =0 and the HP UCI =1, so that the performance of the HP UCI can be ensured. Specifically, the modulation scheme of the points shown in graph 1 satisfies:

where b (2 i) represents the bit value of HPUCI and b (2i + 1) represents the bit value of LPUCI.

The modulation scheme of the points shown in graph 2 satisfies:

where b (2 i) represents the bit value of LP UCI and b (2i + 1) represents the bit value of HP UCI.

That is, the modulation symbols satisfy:

wherein, if m > n, b (2 i) represents the bit value of HP UCI, b (2i + 1) represents the bit value of LP UCI, if m < n, b (2 i) represents the bit value of LP UCI, and b (2i + 1) represents the bit value of HP UCI. For example, m =4,n =1, and therefore the modulation symbol determined from the first parameter value and the second parameter value satisfies:

wherein b (2 i) represents the bit value of HP UCI, and b (2i + 1) represents the bit value of LP UCI.

For another example, m =1,n =4, and therefore the modulation symbol determined according to the first parameter value and the second parameter value satisfies:

S303, mapping the modulation symbol to a physical channel, and transmitting the physical channel.

In some possible embodiments, after the modulation symbols are determined, the modulation symbols may be mapped to a physical channel and the physical channel may be transmitted. Here, mapping the modulation symbols to the physical channel may be understood as first generating a sequence y (n) of the PUCCH format 1 according to the modulation symbols (see the above formula 1), and further obtaining z (n) according to the sequence y (n) of the PUCCH format 1 (see the above formula 5), so as to map z (n) to the PUCCH and transmit the PUCCH. That is, the first information and the second information are carried on the PUCCH.

When the first information and the second information are UCI, the physical channel may be PUCCH, that is, the terminal device sends PUCCH to the access network device, so the access network device may receive PUCCH from the terminal device. Further, the access network device may obtain a modulation symbol mapped on the physical channel, and determine a first parameter value and a second parameter value according to the modulation symbol, where an absolute value of the first parameter value is greater than an absolute value of the second parameter value. Then, the access network equipment determines the bit value of the first information according to the first parameter value, and determines the bit value of the second information according to the second parameter value. Wherein the priority of the first information is higher than the priority of the second information. The modulation symbols satisfy:

d (i) = M × { x (i) + j × y (i) } or d (i) = M × { y (i) + j × x (i) };

wherein d (i) is a modulation symbol, x (i) is a first parameter value, y (i) is a second parameter value, i is an index of the modulation symbol, j is an imaginary unit, and M is a preset value. That is, the access network device may parse out the information (i.e., the first information and the second information) carried on the PUCCH. When the first information and the second information are traffic data, the physical channel may be a PUSCH (i.e., the terminal device transmits a PUSCH to the access network device), and thus the access network device may receive the PUSCH from the terminal device. Further, the access network device may obtain a modulation symbol mapped on the PUSCH, and determine the first parameter value and the second parameter value according to the modulation symbol, where an absolute value of the first parameter value is greater than an absolute value of the second parameter value. Then, the access network equipment determines the bit value of the first information according to the first parameter value, and determines the bit value of the second information according to the second parameter value. Wherein the priority of the first information is higher than the priority of the second information. The modulation symbols satisfy:

d (i) = M × { x (i) + j × y (i) } or d (i) = M × { y (i) + j × x (i) };

wherein d (i) is a modulation symbol, x (i) is a first parameter value, y (i) is a second parameter value, i is an index of the modulation symbol, j is an imaginary unit, and M is a preset value. That is, the access network device may parse out the information (i.e., the first information and the second information) carried on the PUSCH.

Optionally, when the first information and the second information are downlink traffic data, the physical channel may be a PDSCH, that is, the access network device sends the PDSCH to the terminal device, so that the terminal device may receive the PDSCH from the access network device. Further, the terminal device may obtain a modulation symbol mapped on the PDSCH, and determine a first parameter value and a second parameter value according to the modulation symbol, where an absolute value of the first parameter value is greater than an absolute value of the second parameter value. Then, the terminal device determines the bit value of the first information according to the first parameter value, and determines the bit value of the second information according to the second parameter value. Wherein the priority of the first information is higher than the priority of the second information. The modulation symbols satisfy:

d (i) = M × { x (i) + j × y (i) } or d (i) = M × { y (i) + j × x (i) };

wherein d (i) is a modulation symbol, x (i) is a first parameter value, y (i) is a second parameter value, i is an index of the modulation symbol, j is an imaginary unit, and M is a preset value. That is, the terminal device may parse out information (i.e., the first information and the second information) carried on the PDSCH.

In the embodiment of the application, when the HP UCI is 1 bit and the LP UCI is 1 bit, and is transmitted through the PUCCH format 1, the performance of the HP UCI may be improved through a non-equidistant mapping manner, that is, the reliability of HP UCI transmission is improved.

Exemplarily, please refer to fig. 5, where fig. 5 is another schematic flow diagram of the information transmission method provided in the embodiment of the present application. As shown in fig. 5, the information transmission process between the UE and the base station includes:

step 1: and the base station sends the configuration information of the PUCCH to the UE. The configuration information of the PUCCH may include configuration information of the PUCCH carrying HARQ-ACK, CSI or SR. Specifically, the configuration information of the PUCCH carrying the HARQ-ACK includes PUCCH resource sets, respective PUCCH resources in each resource set, and a maximum number of bits that the PUCCH in each resource set can carry the HARQ-ACK. The configuration information of the PUCCH includes configuration information of a high priority PUCCH and configuration information of a low priority PUCCH.

Step 2: the base station transmits Downlink Control Information (DCI) to the UE. The DCI schedules the PUCCH. Alternatively, the DCI here may also schedule the PDSCH. Wherein step 2 is optional, i.e. there may be no step 2, i.e. no DCI. It is understood that when there is no step 2, the PUCCH in step 3 may be a semi-statically configured PUCCH, for example, a semi-statically scheduled (SPS) PDSCH configured by a higher layer, and the PUCCH is a PUCCH configured by the higher layer to feed back HARQ-ACK of the semi-static PDSCH.

And step 3: the UE transmits PUCCH to the base station. Wherein, the PUCCH carries high-priority UCI and low-priority UCI.

It can be understood that please refer to fig. 6, fig. 6 is a schematic view of a scene of information transmission provided in the embodiment of the present application. As shown in fig. 6, PUCCH carrying HP UCI and LP UCI is PUCCH 3 in fig. 6, PUCCH1 in fig. 6 carries LP UCI, and PUCCH2 in fig. 6 carries HP UCI, but since PUCCH1 and PUCCH2 overlap in the time domain, HP UCI and LP UCI may be multiplexed onto PUCCH 3 to be transmitted. That is, PUCCH 3 may be PUCCH2 or PUCCH1, that is, LP UCI may be simultaneously transmitted on PUCCH2 for transmitting HP UCI (that is, PUCCH2 is multiplexed as PUCCH 3), HP UCI may be simultaneously transmitted on PUCCH1 for transmitting LP UCI (that is, PUCCH1 is multiplexed as PUCCH 3), and PUCCH 3 may be another PUCCH, which is not limited herein. The PUCCH1/2/3 in fig. 6 may be DCI scheduled, or semi-statically configured, which is not limited herein.

When the UE performs modulation mapping on the UCI with the high priority and the UCI with the low priority, the modulation mapping method used may be the description of step S301 and step S302 in fig. 3, which is not described herein again, or may not be the description of step S301 and step S302 in fig. 3, that is, the modulation method in fig. 1 is used, which is not limited herein.

For case 2, please refer to fig. 7, fig. 7 is another schematic flow chart of the information transmission method according to the embodiment of the present application. The method can be applied to the terminal equipment. As shown in fig. 7, the method includes the following steps S701 to S703:

s701, when the length of the bit sequence of the first uplink control information UCI is smaller than a preset bit number, determining a first bit sequence according to the bit sequence of the first UCI and the padding bits.

In some possible embodiments, when the length of the bit sequence of the first uplink control information UCI is less than a preset number of bits, the first bit sequence is determined according to the bit sequence of the first UCI and the padding bits. Wherein, the length of the first bit sequence is equal to the preset bit number. That is to say, when the length of the bit sequence of the first UCI is smaller than the preset number of bits, the terminal device may complement the bit sequence of the first UCI to the preset number of bits to obtain the first bit sequence. Optionally, when the length of the bit sequence of the second UCI is smaller than the preset number of bits, the second bit sequence is determined according to the bit sequence of the second UCI and the padding bits, and the length of the second bit sequence is equal to the preset number of bits. That is to say, when the length of the bit sequence of the second UCI is smaller than the preset number of bits, the terminal device may complement the bit sequence of the second UCI to the preset number of bits to obtain the second bit sequence. Wherein the priority of the second UCI is different from the priority of the first UCI. For example, the priority of the first UCI may be higher than the priority of the second UCI, or the priority of the second UCI may be higher than the priority of the first UCI, without limitation. For convenience of understanding, the following embodiments of the present application are schematically illustrated by taking the case where the priority of the first UCI is higher than that of the second UCI. The first UCI and the second UCI may be HARQ-ACK, or the first UCI and the second UCI are CSI, or the first UCI and the second UCI are SR, and the like, which is not limited herein. The first UCI may further include HARQ-ACK and SR, and the second UCI may further include HARQ-ACK and SR. Wherein the first UCI and the second UCI can be multiplexed together and transmitted through one PUCCH. Here, the PUCCH may be any one of PUCCH format2, PUCCH format3, PUCCH format4, and the like, and is not limited herein.

The padding of the bit sequence of the first UCI to the predetermined number of bits may be: and zero padding the bit sequence of the first UCI to a preset bit number to obtain a first bit sequence. That is, the bit value of the padding bit is 0. Specifically, the zero padding position may be zero padding for a high bit of the bit sequence of the first UCI, or may be zero padding for a low bit of the bit sequence of the first UCI, and the like, which is not limited herein. For example, assuming that the preset number of bits is 3 bits, where the sequence of the first UCI is 10, the first bit sequence obtained by padding zeros in the high bits of the bit sequence of the first UCI is 010, and the first bit sequence obtained by padding zeros in the low bits of the bit sequence of the first UCI is 100.

Optionally, padding the bit sequence of the first UCI to a preset number of bits may also be understood as: and supplementing 1 to a preset bit number to the bit sequence of the first UCI to obtain a first bit sequence. That is, the bit value of the padding bit is 1. Specifically, the 1-padding position may be a 1-padding at a high bit of the bit sequence of the first UCI, or may be a 1-padding at a low bit of the bit sequence of the first UCI, and the like, which is not limited herein. For example, assuming that the preset number of bits is 3 bits, where the sequence of the first UCI is 10, the first bit sequence obtained by complementing 1 in the high bit of the bit sequence of the first UCI is 110, and the first bit sequence obtained by complementing 1 in the low bit of the bit sequence of the first UCI is 101.

Optionally, padding the bit sequence of the first UCI to a preset number of bits may also be understood as: and the bit sequence of the first UCI is filled to a preset bit number by adopting a mode of repeating the bit value in the bit sequence of the first UCI, so as to obtain a first bit sequence. Specifically, the bit value of the upper bit in the bit sequence of the first UCI may be repeated at the upper bit of the bit sequence of the first UCI to complement the bit sequence of the first UCI to the preset bit number. That is, the bit value of the padding bit is the bit value of the upper bit in the bit sequence of the first UCI. Alternatively, the bit value of the low bit in the bit sequence of the first UCI may be repeated at the low bit of the bit sequence of the first UCI to complement the bit sequence of the first UCI to a preset bit number, and the like, which is not limited herein. That is, the bit value of the padding bit is the bit value of the low bit in the bit sequence of the first UCI. For example, assuming that the preset number of bits is 3 bits, wherein the sequence of the first UCI is 10, the bit value of the upper bit of the bit sequence of the first UCI is repeated at the upper bit of the bit sequence of the first UCI to complement the bit sequence of the first UCI to the preset number of bits, and the resulting first bit sequence may be 110. For another example, bit values of low bits in the bit sequence of the first UCI are repeated at the low bits of the bit sequence of the first UCI to complement the bit sequence of the first UCI to a preset number of bits, and the resulting first bit sequence may be 100.

Optionally, padding the bit sequence of the first UCI to a preset number of bits may also be understood as: and determining a target bit value for supplementing to a preset bit number by performing exclusive-or operation on the bit value in the bit sequence of the first UCI, and further supplementing the target bit value to the preset bit number by the bit sequence of the first UCI to obtain a first bit sequence. That is, the bit value of the padding bit is a value obtained by xoring the bit values in the bit sequence of the first UCI (i.e., a target bit value). Specifically, the complementary target bit value position may be a higher-order complementary target bit value of the bit sequence of the first UCI, or may be a lower-order complementary target bit value of the bit sequence of the first UCI, and the like, which is not limited herein. For example, assuming that the preset number of bits is 3 bits, where the sequence of the first UCI is 10, and thus the target bit value is equal to 1 (i.e., 1 or 0 is equal to 1), the first bit sequence obtained by complementing the target bit value at the high bits of the bit sequence of the first UCI is 110, and the first bit sequence obtained by complementing the target bit value at the low bits of the bit sequence of the first UCI is 101.

For convenience of understanding, the following embodiments of the present application take the example of padding to zero to a predetermined number of bits as an example. It can be understood that the filling manner for filling the bit sequence of the second UCI to the predetermined bit number may refer to the filling manner for filling the bit sequence of the first UCI to the predetermined bit number, and will not be described herein again. Wherein, the preset number of bits may be greater than or equal to 3 bits. For convenience of understanding, the following embodiments of the present application are schematically illustrated by taking the preset number of bits as 3 bits. That is, when the PUCCH is format 2/3/4, and simultaneously carries the HP UCI and the LP UCI, and the total bit number is >3, if the HP UCI bit number is smaller than the preset bit number 3, the HP UCI is padded to 3 bits, and then a 3-bit UCI coding scheme is adopted. And if the number of the LP UCI bits is less than 3, padding the LP UCI into 3 bits, and then using a UCI coding mode with 3 bits. Specifically, as shown in table 6.

Table 6

Number of UCI bits	UCI bits	Padding to bits after 3 bits
			1	Bit of UCI is c ₀	c ₀ 0,0; or 0, c ₀ (ii) a Or c ₀ ,c ₀ ,c ₀
2	Bit of UCI is c ₀ ,c ₁	c ₀ ,c ₁ 0; or 0,c ₀ ,c ₁ (ii) a Or c ₀ ,c ₁ ,c ₀ XOR c ₁

S702, channel coding is carried out on the first bit sequence to obtain a first coded bit sequence.

In some possible embodiments, the first bit sequence is channel coded to obtain a first coded bit sequence. And performing channel coding on the second bit sequence to obtain a second coded bit sequence. That is, channel coding may be performed on a first UCI satisfying a preset number of bits and on a second UCI satisfying the preset number of bits, respectively, to obtain a first coded bit sequence and a second coded bit sequence. The channel coding method can be shown in the above equation 6, and is not described herein again.

And S703, mapping the first coded bit sequence to a Physical Uplink Control Channel (PUCCH), and transmitting the PUCCH.

In some possible embodiments, the first coded bit sequence is mapped to a physical uplink control channel, PUCCH, and the second coded bit sequence is mapped to the physical uplink control channel, PUCCH, and the PUCCH is transmitted to the access network device. Therefore, after the access network device receives the PUCCH from the terminal device, a first coded bit sequence and a second coded bit sequence mapped on the PUCCH may be obtained, where the first coded bit sequence corresponds to the first uplink control information UCI, the second coded bit sequence corresponds to the second UCI, and a priority of the second UCI is different from a priority of the first UCI. Further, the access network device may determine a first bit sequence from the first coded bit sequence and a second bit sequence from the second coded bit sequence. Then, the access network device determines a bit sequence of a first UCI according to the first bit sequence, and determines a bit sequence of a second UCI according to the second bit sequence, wherein the length of the first bit sequence is a preset number of bits, and the bit sequence of the first UCI is smaller than the preset number of bits. Optionally, the length of the second bit sequence is a preset number of bits, and the bit sequence of the second UCI may also be smaller than the preset number of bits, which is specifically determined according to an actual application scenario, and is not limited herein. That is, after the access network device receives the PUCCH, the information (i.e., the first UCI and the second UCI) carried on the PUCCH may be parsed. Wherein the bit sequence of the first UCI is a bit of the first bit sequence except for the padding bit. Optionally, the bit sequence of the second UCI may also be bits other than the padding bits in the second bit sequence, which is determined specifically according to an actual application scenario, and is not limited herein.

For example, when the length of the bit sequence of the first UCI is 1 bit and the filling position of the filling bit is to add the filling bit at the low bit position of the bit sequence of the first UCI, if the access network device determines that the first bit sequence is c according to the received PUCCH ₀ ,c ₁ ,c ₂ The access network equipment may then assign the first bit sequence c ₀ ,c ₁ ,c ₂ C in (1) ₀ A bit sequence of the first UCI is determined. For another example, when the length of the bit sequence of the first UCI is 2 bits and the padding position of the padding bit is to add the padding bit at the low bit position of the bit sequence of the first UCI, if the access network device determines that the first bit sequence is c according to the received PUCCH ₀ ,c ₁ ,c ₂ The access network equipment may then transmit the first bit sequence c ₀ ,c ₁ ,c ₂ C in (1) ₀ ,c ₁ A bit sequence of the first UCI is determined.

In the implementation of the application, when the HP UCI and the LP UCI are sent through PUCCH format 2/3/4, if the number of bits of the UCI (i.e., the HP UCI and/or the LP UCI) is less than 3, the HP UCI and the LP UCI are padded to 3 bits, and then the padded HP UCI and LP UCI are separately encoded by using a UCI encoding method of 3 bits, so that the transmission reliability of the HP UCI can be improved, and the implementation complexity of the terminal device can be reduced.

The information transmission device provided by the present application will be described in detail below with reference to fig. 8 to 9.

Referring to fig. 8, fig. 8 is a schematic structural diagram of an information transmission device according to an embodiment of the present disclosure. The information transmission apparatus 80 shown in fig. 8 may be used to perform part or all of the functions of the terminal device in the method embodiments described in fig. 3 to fig. 7. The apparatus may be a terminal device, an apparatus in the terminal device, or an apparatus capable of being used in cooperation with the terminal device. The information transmission device 80 may also be a chip system. The information transmission apparatus 80 shown in fig. 8 may include a transceiving unit 801 and a processing unit 802. The processing unit 802 is configured to perform data processing. The transceiver unit 801 is integrated with a receiving unit and a transmitting unit. The transceiving unit 801 may also be referred to as a communication unit. Alternatively, the transceiver unit 801 may be divided into a receiving unit and a transmitting unit. The processing unit 802 and the transceiver unit 801 are similar in structure and will not be described in detail below. Wherein:

in one implementation, the processing unit 802 is configured to determine a first parameter value according to a bit value of first information, and determine a second parameter value according to a bit value of second information, where an absolute value of the first parameter value is greater than an absolute value of the second parameter value, and a priority of the first information is higher than a priority of the second information;
