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

Referring to fig. 2, fig. 2 is a flowchart of an information transmission method provided in an embodiment of the present application, where the method is applied to a terminal, and as shown in fig. 2, the method includes the following steps:

step 21: the terminal acquires UCI to be transmitted.

In this embodiment, the UCI to be transmitted may include, but is not limited to, Scheduling Request (SR), Channel State Information (CSI), Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) feedback Information, and the like.

In an embodiment, the UCI to be transmitted is information to be transmitted in a conventional PUCCH. The legacy PUCCH may be understood as a normal PUCCH. For example, the conventional PUCCH may include, but is not limited to, PUCCH in 4 formats under Release 16 of NR-unisense (e.g., format0, format1, format2, format3), PUCCH in 5 formats under Release 15 of NR (e.g., format0, format1, format2, format3, format4), PUCCH in 7 formats under Release 14 of LTE and LTE-a (e.g., format1, format1a, format1b, format2, format2a, format3, format3b), and the like. Optionally, the legacy PUCCH may include a Demodulation Reference Signal (DMRS) -based PUCCH, which may be considered as a DMRS-carrying transmission and used in a channel estimation and Demodulation process at a receiving end.

Step 22: and the terminal multiplexes the UCI to be transmitted to the first PUCCH for transmission.

In this embodiment, the first PUCCH is a sequence-based PUCCH. The sequence-based PUCCH may be understood as a PUCCH of a new format. Taking fig. 3 as an example, fig. 3 illustrates a sequence-based PUCCH transmission scheme using a 12-long sequence as a carrier sequence, where each Orthogonal Frequency Division Multiplexing (OFDM) symbol (or simply referred to as a symbol) can carry 1 to 2 bits of information, and the sequences with the same padding pattern represent the same sequence, that is, the OFDM symbols are repeated to improve transmission performance.

Note that, in the embodiment of the present application, the bearer sequence of the PUCCH based on sequence is not limited to a 12-long sequence, and bearer sequences with other lengths may also be used, for example, 8, 10, and the like. The embodiment of the application can be suitable for information transmission of less than 11 bits of PUCCH format3 or PUCCH format 4.

According to the information transmission method, after the terminal acquires the UCI to be transmitted, the UCI to be transmitted can be multiplexed on the PUCCH based on the sequence for transmission. Therefore, by means of the PUCCH based on the sequence, the UCI to be transmitted can be attached to the sequence for transmission, and the complexity of coding is not required to be replaced by the transmission performance, so that the transmission performance is improved, and the communication process is ensured.

In this embodiment of the application, optionally, the process of multiplexing the UCI to be transmitted on the first PUCCH for transmission may include: firstly, a terminal determines bit information of UCI to be transmitted; then, the terminal determines a signal sequence when the UCI to be transmitted is multiplexed on the first PUCCH for transmission according to the bit information of the UCI to be transmitted; finally, the terminal transmits the signal sequence on the first PUCCH. In this way, by means of the signal sequence, the UCI to be transmitted can be multiplexed on the PUCCH based on the sequence for transmission.

In an embodiment, when determining a signal sequence when the UCI to be transmitted is multiplexed on the first PUCCH for transmission according to bit information of the UCI to be transmitted, the terminal may determine the signal sequence by combining an information correspondence table that is predefined or configured by the network side device, where the information correspondence table is a correspondence table between the UCI bit information and a corresponding signal sequence. The signal sequence may be selected as an Orthogonal Cover Code (OCC) sequence in the time domain, a phase rotation related sequence, or the like.

Optionally, in order to ensure multiplexing transmission of UCI, the multiplexing the UCI to be transmitted on the first PUCCH for transmission may include: firstly, a terminal determines a first metric value when UCI to be transmitted is multiplexed on a first PUCCH for transmission; and then, the terminal multiplexes the UCI to be transmitted to a first PUCCH for transmission under the condition that the first metric value is smaller than a preset threshold value. The preset threshold may be agreed in advance, such as agreed by a protocol, or may be configured by a network side device.

Optionally, the determining a first metric value when the UCI to be transmitted is multiplexed on the first PUCCH for transmission may include:

the terminal determines the first metric value according to at least one of the following:

the bit number N of UCI to be transmitted; nmin is more than or equal to N and less than or equal to Nmax, the Nmin and the Nmax can be set based on actual requirements, and the Nmin, the N and the Nmax are positive integers;

multiplexing UCI to be transmitted to a symbol number M occupied by a signal sequence when the UCI is transmitted on a first PUCCH;

the number of bits N1 that each symbol or each sequence of the first PUCCH can carry;

a sequence-dependent form of the first PUCCH; wherein, the form can be selected as ZC sequence, m sequence, Gold sequence, etc.;

a modulation order Qm of the sequence of the first PUCCH.

Further, the terminal may calculate the first metric value by any one of the following formulas:

N/M；

N/(M*Qm)；

N/(M*N1)；

N/(M*N1*Qm)。

in this embodiment of the application, the terminal may multiplex the UCI to be transmitted to the first PUCCH in multiple ways, which is described in detail below.

1) The terminal can multiplex the UCI to be transmitted to the first PUCCH for transmission through the time domain OCC sequence.

Optionally, in this 1), different multiplexing information bits may correspond to different time domain OCC sequences; and/or for a first transmission that employs symbol repetition, the time domain OCC sequence corresponding to the first transmission is repeated. For example, for each transmission that employs OFDM symbol repetition, the time domain OCC sequence corresponding to the transmission is also repeated.

2) The terminal can multiplex the UCI to be transmitted to the first PUCCH for transmission through different phase rotations among the time domain symbols.

Optionally, in this 2), different multiplexed information bits may correspond to different phase rotations; and/or for a second transmission that employs symbol repetition, the second transmission is repeated with a corresponding phase rotation. For example, for each transmission that takes the OFDM symbol repetition, the phase rotation associated with that transmission is also repeated.

3) The terminal can multiplex the UCI to be transmitted to the first PUCCH for transmission in a mode of joint coding on the first PUCCH.

Optionally, in this 3), the number of symbols of the extended transmission of the first PUCCH may be determined according to the following:

a total number of bits of the transmission content on the first PUCCH; it should be noted that the content transmitted on the first PUCCH at least includes UCI to be transmitted of the first PUCCH, in addition to UCI to be transmitted of the conventional PUCCH;

and uplink and downlink configuration information of symbols in the slot corresponding to the first PUCCH.

For example, when the number of bits of UCI to be transmitted in both the conventional PUCCH and the sequence-based PUCCH is less than or equal to 11, the terminal may perform multiplexing transmission by using a joint coding method on the sequence-based PUCCH. When the joint coding is performed, the terminal can adaptively expand the number of transmission symbols M according to the number of bits of the common transmission information during multiplexing and the uplink and downlink configuration information of the symbols in the slot, where M is less than or equal to Mmax, and the Mmax can be set based on actual requirements.

4) The terminal may multiplex the UCI to be transmitted onto the first PUCCH for transmission by increasing the number of portable bits for each sequence of the first PUCCH.

Optionally, in this 4), the increasing of the number of portable bits for each sequence of the first PUCCH may be implemented by at least one of the following:

increasing a cyclic prefix within the sequence;

increasing the length of the base sequence.

For example, in the case where the number of bits of UCI to be transmitted in both the conventional PUCCH and the sequence-based PUCCH is less than or equal to 11, the terminal may first increase the number of portable bits for each sequence of the sequence-based PUCCH, and then perform multiplexing transmission of joint coding on the sequence-based PUCCH.

Optionally, in 1) to 4), the number of bits of the UCI to be transmitted is less than or equal to a first threshold. The first threshold may be agreed in advance, such as agreed by a protocol, or may be configured by a network side device. For example, the first threshold value is 11.

In this embodiment of the application, optionally, when the number of bits of the UCI to be transmitted of the conventional PUCCH is greater than the second threshold and the number of bits of the UCI to be transmitted of the first PUCCH is greater than the third threshold, when the terminal multiplexes the UCI to be transmitted of the conventional PUCCH onto the first PUCCH for transmission, the UCI to be transmitted of the conventional PUCCH may be compressed first to obtain compressed UCI, the number of bits of the compressed UCI is less than or equal to the second threshold, and then the compressed UCI is multiplexed onto the first PUCCH for transmission, so as to ensure performance of a multiplexing transmission process.

Optionally, when the number of bits of the UCI to be transmitted of the conventional PUCCH is greater than the second threshold and the number of bits of the UCI to be transmitted of the first PUCCH is greater than the third threshold, the terminal may further transmit the UCI to be transmitted by using the conventional PUCCH according to the first PUCCH format, where the first PUCCH format is configured by the network side device or agreed by the protocol.

Optionally, the first PUCCH format may be any one of the following: PUCCH format2, PUCCH format3, PUCCH format 4.

In this embodiment of the application, for a conventional PUCCH whose number of portable bits is greater than the fourth threshold, optionally, the terminal may multiplex the first PUCCH, that is, the UCI to be transmitted of the PUCCH based on the sequence, to the conventional PUCCH for transmission.

Further, the terminal may multiplex the UCI to be transmitted of the sequence-based PUCCH onto the legacy PUCCH for joint coded transmission.

It should be noted that the second threshold, the third threshold, and the fourth threshold may be agreed in advance, for example, agreed by a protocol, or may be configured by a network side device. The second threshold, the third threshold and the fourth threshold may be the same or different. In one embodiment, the second threshold, the third threshold and the fourth threshold are all selected to be 11.

The present application is described in detail below with reference to the following figures and specific examples.

Example 1

In this embodiment 1, multiplexing a conventional PUCCH into a sequence-based PUCCH is implemented by using a time domain OCC sequence. Let the PUCCH transmission mode based on the sequence be a 12-long sequence, the time domain occupies 4 OFDM symbols, and the metric value is smaller than the preset threshold Q, as shown in fig. 3.

Assuming that the number of UCI bits to be transmitted in the conventional PUCCH is 2 and the transmission bit is 01, when multiplexing the conventional PUCCH onto the sequence-based PUCCH for transmission, the corresponding signal sequence may be determined to be [ + 1-1 + 1-1 ] in combination with the definition of the time domain OCC sequence in table 1 below, and the signal sequence may be transmitted on the sequence-based PUCCH, as shown in fig. 4.

TABLE 1

Load (payload)	OCC sequence w_n(i)
		00	[+1 +1 +1 +1]
01	[+1 -1 +1 -1]
		10	[+1 +1 -1 -1]
11	[+1 -1 -1 +1]

Example 2

In this embodiment 2, multiplexing a conventional PUCCH into a sequence-based PUCCH is implemented by using a time domain OCC sequence. If OFDM symbol repetition transmission is employed, the time domain OCC sequence is repeated as well. The PUCCH transmission mode based on the sequence is a 12-long sequence, and since the PUCCH transmission mode is repeatedly transmitted once, the time domain occupies 8 OFDM symbols, and the metric value thereof is smaller than the preset threshold Q.

Assuming that the number of UCI bits to be transmitted in the conventional PUCCH is 2, and the transmission bit is 01, when multiplexing the conventional PUCCH onto the sequence-based PUCCH for transmission and repeating the transmission once, the corresponding signal sequence may be determined to be [ + 1-1 + 1-1 ] in combination with the definition of the time-domain OCC sequence in table 1 above, and the signal sequence may be transmitted on the sequence-based PUCCH, as shown in fig. 5. In fig. 5, as the OFDM symbol is repeated, the time domain OCC sequence is also repeated.

Example 3

In this embodiment 3, multiplexing of the conventional PUCCH into the sequence-based PUCCH is implemented by phase rotation. The PUCCH transmission mode based on the sequence is a 12-length sequence, the time domain occupies 4 OFDM symbols, and the measurement value is smaller than a preset threshold value Q.

Assuming that the number of UCI bits to be transmitted of the conventional PUCCH is 2 and the transmission bit is 01, when multiplexing the PUCCH based on sequence, the corresponding phase index may be determined to be [ -1210 ] in combination with the phase definition as in table 2 below when transmitting the PUCCH based on sequence]The sequence corresponding to the index is

And transmits the phase index on the sequence-based PUCCH as shown in fig. 6.

TABLE 2

payload	Phase
		00	[-1 0 1 2]
01	[-1 2 1 0]
		10	[-1 0 2 1]
11	[-1 1 2 0]

Example 4

In this embodiment 4, the conventional PUCCH is multiplexed into the sequence-based PUCCH, and the multiplexing is implemented by phase rotation. If OFDM symbol repetition transmission is employed, the phase rotation is repeated as well. The PUCCH transmission mode based on the sequence is a 12-long sequence, and since the PUCCH transmission mode is repeatedly transmitted once, the time domain occupies 8 OFDM symbols, and the metric value thereof is smaller than the preset threshold Q.

Assuming that the number of UCI bits to be transmitted of the conventional PUCCH is 2 and the transmission bit is 01, when multiplexing the conventional PUCCH for transmission and repeating the transmission once, the corresponding phase index may be determined to be [ -1210 ] in combination with the phase definition as in table 2 above]The sequence corresponding to the index is

And transmits the phase index on the sequence-based PUCCH as shown in fig. 7. In fig. 7, as OFDM symbols are repeated, phase rotation is also repeated.

Example 5

In this embodiment 5, when the number of bits of UCI to be transmitted in both the conventional PUCCH and the sequence-based PUCCH is less than or equal to 11, multiplexing transmission is performed by using a joint coding method on the sequence-based PUCCH, and it is ensured that the metric value is less than Q. When performing joint coding, the terminal may perform spreading of the number of transmitted symbols according to the number of bits of the common transmission information during multiplexing and the uplink and downlink configuration information of the symbols in the slot.

It is assumed that each OFDM symbol in the PUCCH based on the sequence may carry 2 bits, in this embodiment, the PUCCH based on the sequence carries 8-bit information in total, and the OFDM symbol of the conventional PUCCH carries 2-bit information, and after the OFDM symbol of the conventional PUCCH and the OFDM symbol of the conventional PUCCH are jointly encoded, the two symbols are uniformly transmitted in the time-frequency resource of the PUCCH based on the sequence, as shown in fig. 8, where the part containing the checkered pattern is bit information originally belonging to the conventional PUCCH, multiplexed into the PUCCH based on the sequence.

Example 6

In this embodiment 6, the total number of transmission bits of the PUCCH based on the sequence is 4 bits, each OFDM symbol can carry 1-bit information, and the transmission method is as shown in fig. 9. It is assumed that the conventional PUCCH carries 4 bits of information in total, and after the two PUCCHs are multiplexed, the time-frequency resources occupied by the PUCCH based on the sequence are unchanged, but the number of bits that can be carried by each OFDM symbol is increased from 1 bit to 2 bits by increasing the sequence phase or cyclic shift, so as to form the transmission mode shown in fig. 10. In fig. 10, the bold frame represents that the number of bits that can be carried by the OFDM symbol is increased from 1 bit to 2 bits, and it is also ensured that the metric value is smaller than the preset threshold Q.

Example 7

In this embodiment 7, the total number of transmission bits of the PUCCH based on the sequence is 4 bits, each OFDM symbol can carry 1-bit information, and the transmission method is as shown in fig. 11. The traditional PUCCHs are designed to carry 4-bit information in total, and after the traditional PUCCHs and the traditional PUCCHs are multiplexed, the length of a base sequence of the PUCCH based on the sequence is doubled so as to bear one more bit number. In this embodiment 7, the sequence is spread in the time domain to form the transmission scheme as shown in fig. 12, and at this time, it is also ensured that the metric value is smaller than the preset threshold Q.

Example 8

In this embodiment 8, the total number of transmission bits of the PUCCH based on the sequence is 4 bits, each OFDM symbol can carry 1-bit information, and the transmission method is as shown in fig. 11. The traditional PUCCHs are designed to carry 4-bit information in total, and after the traditional PUCCHs and the traditional PUCCHs are multiplexed, the length of a base sequence of the PUCCH based on the sequence is doubled so as to bear one more bit number. In this embodiment 8, the sequence is spread in the frequency domain to form the transmission scheme shown in fig. 13, and at this time, it is also ensured that the metric value is smaller than the preset threshold Q.
