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

Please refer to FIG. 2, which is a flowchart of an information transmission method provided in an embodiment of the present application. The method is applied to a terminal. As shown in FIG. 2, the method includes the following steps:

Step 21: The terminal obtains the UCI to be transmitted.

In this embodiment, the above-mentioned UCI to be transmitted may include but is not limited to a scheduling request (Scheduling Request, SR), channel state information (Channel State Information, CSI), hybrid automatic repeat request confirmation (Hybrid Automatic Repeat reQuest Acknowledgement, HARQ-ACK) feedback information, etc.

In one implementation, the above-mentioned UCI to be transmitted is the information to be transmitted of the traditional PUCCH. The traditional PUCCH can be understood as a conventional PUCCH. For example, the traditional PUCCH may include but is not limited to PUCCHs of 4 formats (such as format0, format1, format2, format3) under Release 16 of NR-unlicense, PUCCHs of 5 formats (such as format0, format1, format2, format3, format4) under Release 15 of NR, and PUCCHs of 7 formats (such as format1, format1a, format1b, format2, format2a, format3, format3b) under Release 14 of LTE and LTE-A. Optionally, the traditional PUCCH may include a PUCCH based on a demodulation reference signal (DMRS), where DMRS can be considered to be carried in the transmission and used for the channel estimation and demodulation process of the receiving end.

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

In this embodiment, the first PUCCH is a sequence-based PUCCH. The sequence-based PUCCH can be understood as a new format of PUCCH. Taking Figure 3 as an example, Figure 3 illustrates a sequence-based PUCCH transmission method with a 12-long sequence as the carrier sequence, wherein each orthogonal frequency division multiplexing (OFDM) symbol (or simply referred to as: symbol) can carry 1 to 2 bits of information, and the sequence of the same filling pattern represents the same sequence, that is, the OFDM symbol is repeated to improve the transmission performance.

It should be noted that the sequence-based PUCCH bearer sequence in the embodiment of the present application is not limited to a 12-bit sequence, and other lengths of bearer sequences may also be used, such as 8, 10, etc. The embodiment of the present application is applicable to information transmission of less than 11 bits in PUCCH format 3 or PUCCH format 4.

In the information transmission method of the embodiment of the present application, after the terminal obtains the UCI to be transmitted, the UCI to be transmitted can be multiplexed into the sequence-based PUCCH for transmission. Thus, with the help of the sequence-based PUCCH, the UCI to be transmitted can be attached to the sequence for transmission without exchanging the complexity of coding at the cost of transmission performance, thereby improving the transmission performance and ensuring the communication process.

In the embodiment of the present application, optionally, the process of multiplexing the UCI to be transmitted onto the first PUCCH for transmission may include: first, the terminal determines the bit information of the UCI to be transmitted; then, the terminal determines the signal sequence when multiplexing the UCI to be transmitted onto 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, with the help of the signal sequence, the UCI to be transmitted can be multiplexed onto the sequence-based PUCCH for transmission.

In one implementation, when the terminal determines the signal sequence when multiplexing the UCI to be transmitted to the first PUCCH for transmission based on the bit information of the UCI to be transmitted, it can be determined in combination with a pre-defined or network-side device configured information correspondence table, where the information correspondence table is a correspondence table between the UCI bit information and the corresponding signal sequence. The signal sequence can be a time domain orthogonal cover code (OCC) sequence, a sequence related to phase rotation, and the like.

Optionally, in order to ensure the multiplexing transmission of UCI, the process of multiplexing the UCI to be transmitted onto the first PUCCH for transmission may include: first, the terminal determines a first metric value when multiplexing the UCI to be transmitted onto the first PUCCH for transmission; then, when the first metric value is less than a preset threshold, the terminal multiplexes the UCI to be transmitted onto the first PUCCH for transmission. The preset threshold may be pre-agreed such as agreed in a protocol, or may be configured by a network side device, etc.

Optionally, the process of determining the first metric value when multiplexing the UCI to be transmitted onto the first PUCCH for transmission may include:

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

The number of bits of UCI to be transmitted, N; wherein Nmin≤N≤Nmax, Nmin and Nmax may be set based on actual needs, and Nmin, N and Nmax are positive integers;

The number of symbols M occupied by the signal sequence when the UCI to be transmitted is multiplexed onto the first PUCCH for transmission;

The number of bits N1 that can be carried by each symbol or each sequence of the first PUCCH;

A sequence-related form of the first PUCCH; wherein the form may be a ZC sequence, an m sequence, a Gold sequence, etc.;

The modulation order Qm of the first PUCCH sequence.

Furthermore, the terminal may calculate the first metric value by using any of the following formulas:

N/M;

N/(M*Qm);

N/(M*N1);

N/(M*N1*Qm).

In the embodiment of the present application, the terminal may multiplex the above-mentioned UCI to be transmitted onto the first PUCCH for transmission in a variety of ways, as described in detail below.

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

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

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

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

3) The terminal may multiplex the UCI to be transmitted onto the first PUCCH for transmission by means of joint coding on the first PUCCH.

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

The total number of bits of the content transmitted on the first PUCCH; it should be noted that the content transmitted on the first PUCCH includes at least the UCI to be transmitted on the first PUCCH in addition to the UCI to be transmitted on the traditional PUCCH;

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

For example, when the number of bits of UCI to be transmitted in both the traditional PUCCH and the sequence-based PUCCH is less than or equal to 11, the terminal can adopt the joint coding method on the sequence-based PUCCH for multiplexing transmission. When performing joint coding, the terminal can adaptively expand the number of transmission symbols M according to the number of bits of information jointly transmitted 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 Mmax can be set based on actual needs.

4) The terminal may increase the number of bits that can be carried for each sequence of the first PUCCH and multiplex the UCI to be transmitted onto the first PUCCH for transmission.

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

Increase the cyclic prefix within the sequence;

Increase the base sequence length.

For example, when the number of UCI bits to be transmitted for both the traditional PUCCH and the sequence-based PUCCH is less than or equal to 11, the terminal may first increase the number of carryable bits for each sequence of the sequence-based PUCCH, and then perform joint coded multiplexing transmission on the sequence-based PUCCH.

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

In an embodiment of the present application, optionally, when the number of bits of UCI to be transmitted of the traditional PUCCH is greater than the second threshold value, and the number of bits of UCI to be transmitted of the first PUCCH is greater than the third threshold value, when the terminal multiplexes the UCI to be transmitted of the traditional PUCCH to the first PUCCH for transmission, the terminal can first compress the UCI to be transmitted of the traditional PUCCH to obtain a compressed UCI, the number of bits of the compressed UCI is less than or equal to the second threshold value, and then multiplex the compressed UCI to the first PUCCH for transmission, so as to ensure the multiplexing transmission process.

Optionally, when the number of bits of UCI to be transmitted of the traditional PUCCH is greater than the second threshold value, and the number of bits of UCI to be transmitted of the first PUCCH is greater than the third threshold value, the terminal can also transmit the UCI to be transmitted using the traditional PUCCH according to the first PUCCH format, wherein the first PUCCH format is configured by the network side equipment or agreed upon by the protocol.

Optionally, the above-mentioned first PUCCH format may be selected as any one of the following: PUCCH format 2, PUCCH format 3, PUCCH format 4.

In the embodiment of the present application, for a traditional PUCCH that can carry a number of bits greater than a fourth threshold value, optionally, the terminal may multiplex the UCI to be transmitted of the first PUCCH, ie, the sequence-based PUCCH, onto the traditional PUCCH for transmission.

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

It should be noted that the second threshold value, the third threshold value and the fourth threshold value can be pre-agreed such as agreed in the protocol, or can be configured by the network side device. The second threshold value, the third threshold value and the fourth threshold value can be the same or different. In one implementation, the second threshold value, the third threshold value and the fourth threshold value are all selected as 11.

The following drawings and specific embodiments describe the present application in detail.

Example 1

In this embodiment 1, the traditional PUCCH is multiplexed into the sequence-based PUCCH, which will be implemented by using the time domain OCC sequence. Assume that the sequence-based PUCCH transmission method is a 12-length sequence, the time domain occupies 4 OFDM symbols, and its metric value is less than the preset threshold Q, as shown in Figure 3.

Assume that the number of UCI bits to be transmitted of the traditional PUCCH is 2, and the transmission bits are 01. When multiplexed to the sequence-based PUCCH for transmission, combined with the time domain OCC sequence definition in Table 1 below, the corresponding signal sequence can be determined to be [+1 -1 +1 -1], and the signal sequence is transmitted on the sequence-based PUCCH, as shown in Figure 4.

Table 1

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, the traditional PUCCH is multiplexed into the sequence-based PUCCH, which will be implemented by using the time domain OCC sequence. If OFDM symbol repeated transmission is used, the time domain OCC sequence is also repeated. Assume that the sequence-based PUCCH transmission method is a 12-long sequence. Due to repeated transmission once, the time domain occupies 8 OFDM symbols, and its metric value is less than the preset threshold Q.

Assuming that the number of bits of UCI to be transmitted in the traditional PUCCH is 2 and the transmission bits are 01, when multiplexed to the sequence-based PUCCH for transmission and repeated once, combined with the time domain OCC sequence definition in Table 1 above, the corresponding signal sequence can be determined to be [+1 -1 +1 -1], and the signal sequence is transmitted on the sequence-based PUCCH, as shown in Figure 5. In Figure 5, as the OFDM symbol is repeated, the time domain OCC sequence is also repeated.

Example 3

In this embodiment 3, the conventional PUCCH is multiplexed into the sequence-based PUCCH, which is implemented by phase rotation. Assume that the sequence-based PUCCH transmission mode is a 12-length sequence, which occupies 4 OFDM symbols in the time domain, and whose metric value is less than the preset threshold Q.

Assume that the number of bits of UCI to be transmitted in the traditional PUCCH is 2, and the transmission bits are 01. When multiplexed to the sequence-based PUCCH for transmission, combined with the phase definition in Table 2 below, the corresponding phase index can be determined to be [-1 2 1 0]. In practice, the sequence corresponding to this index is And the phase index is transmitted on the sequence-based PUCCH, as shown in FIG6 .

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, which is implemented by phase rotation. If OFDM symbol repetition transmission is adopted, the phase rotation is also repeated. Assume that the sequence-based PUCCH transmission method is a 12-long sequence. Due to repeated transmission once, the time domain occupies 8 OFDM symbols, and its metric value is less than the preset threshold value Q.

Assume that the number of bits of UCI to be transmitted in the traditional PUCCH is 2, and the transmission bits are 01. When multiplexed to the sequence-based PUCCH for transmission and repeated once, combined with the phase definition in Table 2 above, the corresponding phase index can be determined to be [-1 2 1 0]. In practice, the sequence corresponding to this index is The phase index is transmitted on the sequence-based PUCCH, as shown in Figure 7. In Figure 7, as the OFDM symbol is repeated, the phase rotation is also repeated.

Example 5

In this embodiment 5, when the number of bits of UCI to be transmitted in both the traditional PUCCH and the sequence-based PUCCH is less than or equal to 11, joint coding on the sequence-based PUCCH is adopted for multiplexing transmission, and its metric value is guaranteed to be less than Q. When performing joint coding, the terminal can expand the number of transmission symbols according to the number of bits of the information jointly transmitted during multiplexing and the uplink and downlink configuration information of the symbols in the slot.

Assume that each OFDM symbol in the sequence-based PUCCH can carry 2 bits. In this embodiment, the sequence-based PUCCH carries a total of 8 bits of information, and the OFDM symbol of the traditional PUCCH carries 2 bits of information. After the two are jointly encoded, they are uniformly transmitted within the time-frequency resources of the sequence-based PUCCH, as shown in Figure 8, where the part containing the checkered pattern is the bit information originally belonging to the traditional PUCCH that is multiplexed into the sequence-based PUCCH for transmission.

Example 6

In this embodiment 6, it is assumed that the total number of bits transmitted by the sequence-based PUCCH is 4 bits, and each OFDM symbol can carry 1 bit of information, and the transmission method is shown in Figure 9. It is assumed that the traditional PUCCH carries a total of 4 bits of information. After the two are multiplexed, the time-frequency resources occupied by the sequence-based PUCCH transmission remain unchanged, but by increasing the sequence phase or cyclic shift, the number of bits that can be carried by each OFDM symbol is increased from 1 bit to 2 bits, forming a transmission method as shown in Figure 10. In Figure 10, the bold border portion represents that the number of bits that can be carried by the OFDM symbol has increased from 1 bit to 2 bits, and at this time, it is also necessary to ensure that its metric value is less than the preset threshold value Q.

Example 7

In this embodiment 7, it is assumed that the total number of bits transmitted by the sequence-based PUCCH is 4 bits, and each OFDM symbol can carry 1 bit of information. The transmission method is shown in Figure 11. It is assumed that the traditional PUCCH carries a total of 4 bits of information. After the two are multiplexed, the base sequence length of the sequence-based PUCCH is doubled to carry twice as many bits. In this embodiment 7, the sequence is expanded in the time domain to form a transmission method as shown in Figure 12. At this time, it is also necessary to ensure that its metric value is less than the preset threshold Q.

Example 8

In this embodiment 8, it is assumed that the total number of bits transmitted by the sequence-based PUCCH is 4 bits, and each OFDM symbol can carry 1 bit of information. The transmission method is shown in Figure 11. It is assumed that the traditional PUCCH carries a total of 4 bits of information. After the two are multiplexed, the base sequence length of the sequence-based PUCCH is doubled to carry twice as many bits. In this embodiment 8, the sequence is expanded in the frequency domain to form a transmission method as shown in Figure 13. At this time, it is also necessary to ensure that its metric value is less than the preset threshold Q.
