[0002] Physical uplink control channel (PUCCH) resource determination method: The base station configures 4 physical uplink control channel resource sets (PUCCH resource sets) for the user through high-layer signaling. Each physical uplink control channel resource set contains 32 or 8 resources. The user equipment or terminal (UE) first selects a PUCCH resource set according to the payload size of the uplink control information (UCI) to be transmitted on the PUCCH, and then selects a PUCCH resource in the selected PUCCH resource set according to the physical layer downlink control information.

[0003] When a hybrid automatic repeat-acknowledgement (HARQ-ACK) or a channel state information report (CSI report) is transmitted on PUCCH format 2 or PUCCH format 3, the method for determining the number of physical resource blocks (PRBs) used is as follows:

[0004] Select the minimum number of PRBs that meets the maxCodeRate (maximum coding rate or maximum coding rate) configured by the higher layer For PUCCH transmission, that is, if the number of PRBs configured by the higher layer is used and the maximum coding rate cannot carry the UCI payload size that needs to be transmitted, the UE PUCCH is transmitted on PRB.

[0005] The configuration method and optional values ​​of the maximum coding rate are as follows:

On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0072] like Figure 1As shown, an embodiment of the present invention provides a method for transmitting a physical uplink control channel, which is applied to a terminal, and the method includes:

[0073] Step 11, receiving first configuration information of a physical uplink control channel (PUCCH) sent by a network device, wherein the first configuration information includes a maximum code rate maxCodeRate;

[0074] Step 12: determining frequency domain resources used to transmit the PUCCH according to the maximum code rate in the first configuration information;

[0075] Step 13: Transmit the PUCCH on the determined resources.

[0076] In an optional embodiment of the present invention, the first configuration information includes at least one value in a first candidate value set / table, the first candidate value set / table includes N1 code rates, and the N1 code rates include at least one code rate lower than the preset code rate; N1 is a positive integer, the preset code rate is the lowest code rate in the PUCCH maximum code rate maxCodeRate table, or the preset code rate is the lowest code rate in the maximum code rate maxCodeRate candidate value set included in the first configuration information; optionally, the preset code rate may be 0.08;

[0077] For example, add X low-code rate rows to the maxCodeRate table, where X is a positive integer, such as:

[0078]

[0079]

[0080] Among them, row 0 and row 1 are newly added rows. By adding these low-code rate rows, the reliability of PUCCH transmission can be improved.

[0081] The first candidate value set / table here can be implemented by high-level signaling configuration, for example: PUCCH-MaxCodeRate::=ENUMERATED{m, n, ...zeroDot08, zeroDot15, zeroDot25, zeroDot35, zeroDot45, zeroDot60, zeroDot80}, where m and n represent positive numbers less than 0.08.

[0082] In another optional embodiment of the present invention, the first configuration information includes at least one value in the second candidate value set / table and at least one value in the third candidate value set / table, the second candidate value set / table includes N2 code rates, the third candidate value set / table includes N2 code rates, the second candidate value set / table, and / or the third candidate value set / table includes at least one code rate lower than the preset code rate, the N2 are positive integers, the preset code rate is the lowest code rate in the PUCCH maximum code rate maxCodeRate table, or the preset code rate is the lowest code rate in the maximum code rate maxCodeRate candidate value set contained in the first configuration information, optionally, the preset code rate can be 0.08.

[0083] For example, two maxCodeRate tables are agreed upon in advance for different services / different HARQ codebooks / different PUCCH configurations, one is a second candidate value set / table, and the other is a third candidate value set / table. In the third candidate value set / table, X high-code rate rows are removed and X low-code rate rows are added, where X is a positive integer.

[0084] For example, the second candidate value set / table may be:

[0085]

[0086]

[0087] The third candidate value set / table may be:

[0088] maxCodeRate Code rate 0 0.02 1 0.04 2 0.08 3 0.15 4 0.25 5 0.35 6 0.45 7 Reserved

[0089] The second candidate value set / table here can be implemented by high-level signaling configuration, for example:

[0090] PUCCH-MaxCodeRate::=ENUMERATED{zeroDot08,zeroDot15,zeroDot25,zeroDot35,zeroDot45,zeroDot60,zeroDot80}

[0091] The third candidate value set / table here can be implemented by high-level signaling configuration, for example:

[0092] PUCCH-MaxCodeRate::=ENUMERATED{m,n,…zeroDot08,zeroDot15,zeroDot25,zeroDot35,zeroDot45}, where m and n represent positive numbers less than 0.08.

[0094] By configuring different tables, the third candidate value set / table includes rows with low code rates. Through these different tables and the low code rates in the third candidate value set / table, the reliability of PUCCH transmission (transmission of uplink control information UCI) of URLLC services can be improved.

[0095] In an optional embodiment of the present invention, when the first configuration information includes at least one value in the second candidate value set / table and at least one value in the third candidate value set / table, the maximum code rate for transmitting the PUCCH is determined according to the first identifier.

[0106] Step 123, when determining the number of physical resource blocks (PRBs) used to transmit the PUCCH according to the maximum code rate in the first configuration information, the minimum number of PRBs determined is subtract or increase a third value; or,

[0107] Step 124, when determining the number of physical resource blocks (PRBs) used to transmit the PUCCH according to the maximum code rate in the first configuration information, the minimum number of PRBs determined is Multiply or divide by a fourth value.

[0108] The first value, the second value, the third value and the third fourth value are pre-agreed by the protocol, or are carried in the second configuration information sent by the network device when the terminal receives the second configuration information. The network device can send the second configuration information to the terminal through high-layer signaling.

[0109] In addition, the first value, the second value, the third value and the third fourth value are fixed values, or are determined by at least one of the following information: maximum code rate, PUCCH format and configured PRB number

[0110] In one implementation scenario, when the UCI of the URLLC service is transmitted, the frequency domain resources used to transmit the PUCCH can be determined in the following manner:
