In order to enable the UE to feed back SPS HARQ-ACKs with different bit numbers, Radio Resource Control (RRC) needs to configure multiple PUCCH resources, and when the SPS HARQ-ACK PUCCH and Channel State Information (CSI) PUCCH resources overlap, the UE needs to multiplex the SPS HARQ-ACK and CSI on the CSI PUCCH and transmit the multiplexed UCI using the number of PRBs configured by the CSI PUCCH.

Since the CSI PUCCH is configured by the base station for transmitting the CSI report, an appropriate number of PRBs is generally configured according to the number of bits of the CSI, and at this time, if the SPS HARQ-ACK PUCCH is multiplexed on the CSI PUCCH, the maximum code rate may be exceeded, which may reduce reliability of UCI transmission.

As shown in fig. 1, an embodiment of the present invention provides a method 100 for transmitting uplink control information, which may be performed by a terminal device, in other words, the method may be performed by software or hardware installed in the terminal device, and the method includes the following steps:

s102: multiplexing UCI on the first PUCCH resource, the second PUCCH resource or a third PUCCH resource under the condition that the first PUCCH resource and the second PUCCH resource are overlapped; the first PUCCH resource is a resource for transmitting HARQ-ACK, the PDSCH corresponding to HARQ-ACK does not have a corresponding PDCCH, the second PUCCH resource is a resource for transmitting CSI, the third PUCCH resource is one of a plurality of SPS HARQ-ACK feedback resources configured by the terminal device, and the UCI includes: the HARQ-ACK and the CSI.

The third PUCCH resource is one of the plurality of HARQ-ACK resources configured by the terminal equipment, and the first PUCCH resource is a resource for currently transmitting the HARQ-ACK, so that the third PUCCH resource comprises the first PUCCH resource.

In one implementation, the HARQ-ACK and CSI correspond to the same priority.

Therefore, the UCI can be multiplexed on the first PUCCH resource, the second PUCCH resource or the third PUCCH resource, so that the reliability of UCI transmission is improved.

As shown in fig. 2, an embodiment of the present invention provides a method 200 for transmitting uplink control information, which may be performed by a terminal device, in other words, the method may be performed by software or hardware installed in the terminal device, and the method includes the following steps:

s202: multiplexing UCI on a first PUCCH resource, a second PUCCH resource, and a Scheduling Request (SR) PUCCH resource when the first PUCCH resource, the second PUCCH resource, and the SR PUCCH resource overlap; the first PUCCH resource is a resource for transmitting HARQ-ACK, the PDSCH corresponding to HARQ-ACK does not have a corresponding PDCCH, the second PUCCH resource is a resource for transmitting CSI, the third PUCCH resource is one of a plurality of SPS HARQ-ACK feedback resources configured by the terminal device, and the UCI includes: the HARQ-ACK, SR, and the CSI.

In one implementation, the HARQ-ACK, SR, and CSI correspond to the same priority.

As shown in fig. 3, an embodiment of the present invention provides a method 300 for transmitting uplink control information, which may be performed by a terminal device, in other words, the method may be performed by software or hardware installed in the terminal device, and the method includes the following steps:

s302: multiplexing UCI on the first PUCCH resource, the second PUCCH resource, or a third PUCCH resource.

This step may be implemented by step S102 in the embodiment of fig. 1 or step S202 in the embodiment of fig. 2. For clarity and conciseness of the description, details of a specific implementation manner of step S102 in the embodiment of fig. 1 or step S202 in the embodiment of fig. 2 are not repeated.

In one implementation, in the case of multiplexing UCI to the first PUCCH resource or the second PUCCH resource, that is, in the case of multiplexing UCI to a resource for transmitting HARQ-ACK or a resource for transmitting CSI, the method may further include the steps of:

s304: and under the condition that the UCI is transmitted by using a preset PRB number, if the code rate of the UCI exceeds the maximum code rate of the first PUCCH or the second PUCCH, discarding part or all of the CSI.

The UE may transmit the UCI using a preset number of PRBs, for example, a number of RRC-configured PRBs.

At this time, reliability of UCI transmission may be reduced due to a code rate of UCI exceeding a maximum code rate of the first PUCCH or the second PUCCH.

In this case, through this step, if the code rate of the UCI exceeds the maximum code rate of the first PUCCH or the second PUCCH, part or all of the CSI is discarded, so that the actual code rate of the UCI does not exceed the maximum code rate configured by the RRC, thereby ensuring reliability of UCI transmission.

In one implementation, the UE may discard some or all of the CSI according to a certain rule. For example, when the CSI includes CSI part1 and CSI part 2, the UE discards CSI part 2 first; when the CSI includes a plurality of CSI reports, the CSI report with a low priority is discarded first. The maximum code rate is the PUCCH maximum code rate configured by the base station, for example, configured by a parameter maxCodeRate corresponding to each PUCCH format. Specifically, the maximum code rate of each PUCCH should be the maximum code rate of the PUCCH corresponding to the UCI priority, for example, each PUCCH format has a different maximum code rate, one maximum code rate corresponding to UCI of low priority, and one maximum code rate corresponding to UCI of high priority. And if the UCI is of low priority, the maximum code rate is the maximum code rate corresponding to the UCI of low priority in each PUCCH format.

Therefore, the UCI can be multiplexed on the first PUCCH resource, the second PUCCH resource or the third PUCCH resource, the UCI is transmitted by utilizing the preset PRB number, the actual code rate of the UCI is prevented from exceeding the maximum code rate of the first PUCCH or the second PUCCH, and the reliability of UCI transmission is improved.

As shown in fig. 4, an embodiment of the present invention provides a method 400 for transmitting uplink control information, which may be performed by a terminal device, in other words, the method may be performed by software or hardware installed in the terminal device, and the method includes the following steps:

s402: multiplexing UCI on the first PUCCH resource, the second PUCCH resource, or a third PUCCH resource.

In one implementation, in the case of multiplexing UCI to the first PUCCH resource, that is, in the case of multiplexing UCI to a resource for transmitting HARQ-ACK, the method may further include:

s404: determining a first target PRB number according to the first load of the UCI and the maximum code rate of the first PUCCH, wherein the first load of the UCI comprises CRC.

Under the condition that the first PUCCH resource and the second PUCCH resource are overlapped, the first load of the UCI comprises CRC, HARQ-ACK and CSI; in the case where there is overlap of the first PUCCH resource, the second PUCCH resource, and the SR PUCCH resource, the first payload of UCI includes CRC, HARQ-ACK, SR, and CSI.

It should be noted that when the number of bits of the HARQ-ACK and the CSI is greater than 11 bits, CRC is required to be added for HARQ-ACK and CSI transmission, and when the number of bits of the HARQ-ACK and the CSI is not greater than 11 bits, CRC is not required to be added.

The maximum code rate of the first PUCCH is the maximum code rate corresponding to the first PUCCH and is configured by RRC.

The first target PRB satisfies: the UCI code rate is less than or equal to the minimum PRB number of the maximum code rate of the first PUCCH, the first target PRB number is less than or equal to the PRB number configured by the first PUCCH, and when the first PUCCH is in PUCCH format 2 or PUCCH format 3, the PRB number configured by the first PUCCH is configured by RRC. When the first PUCCH is in PUCCH format 4, the number of PRBs of the first PUCCH is 1. This step mainly applies when the first PUCCH is format 2 or format 3. And if the code rate of the UCI is still larger than the maximum code rate of the first PUCCH when the PRB number configured by the first PUCCH is utilized, the first target PRB is equal to the PRB number configured by the first PUCCH.

S406: and transmitting the UCI by utilizing the first target PRB number.

In an embodiment, if the first target number of PRBs is equal to the number of PRBs configured in the first PUCCH and the code rate of the UCI is greater than the maximum code rate of the first PUCCH, discarding part or all of CSI, so that the code rate of the remaining part of the UCI is less than or equal to the maximum code rate of the first PUCCH.

Therefore, the number of PRBs can be determined based on the load of the UCI, so that the reduction of the transmission reliability caused by the fact that the code rate of the UCI exceeds the maximum code rate of the first PUCCH is avoided, and the reliability of UCI transmission is improved.

As shown in fig. 5, an embodiment of the present invention provides a method 500 for transmitting uplink control information, which may be performed by a terminal device, in other words, the method may be performed by software or hardware installed in the terminal device, and the method includes the following steps:

s502: multiplexing UCI on the first PUCCH resource, the second PUCCH resource, or a third PUCCH resource.

In one implementation, in the case of multiplexing UCI to the third PUCCH resource, that is, in the case of multiplexing UCI to one of multiple resources of feedback SPS HARQ-ACK configured by the terminal device, the method may further include the following steps:

s504: and determining one of the plurality of resources of the feedback SPSHARQ-ACK configured by the terminal equipment as the third PUCCH resource according to a second load of UCI, wherein the second load of UCI does not comprise CRC.

In the case where there is overlap of the first PUCCH resource and the second PUCCH resource, the second payload of UCI includes HARQ-ACK and CSI without CRC; in case there is an overlap of the first PUCCH resource, the second PUCCH resource, and the SR PUCCH resource, the second payload of UCI includes HARQ-ACK, SR, and CSI, but does not include CRC.

S506: and determining a second target PRB number according to the third load of the UCI and the maximum code rate of the third PUCCH, wherein the third load of the UCI comprises CRC.

Under the condition that the first PUCCH resource and the second PUCCH resource are overlapped, a third load of UCI comprises CRC, HARQ-ACK and CSI; in the case where there is overlap of the first PUCCH resource, the second PUCCH resource, and the SR PUCCH resource, the third bearer of the UCI includes CRC, HARQ-ACK, SR, and CSI.

And the maximum code rate of the third PUCCH is the maximum code rate corresponding to the third PUCCH and is configured by RRC.

The second target PRB is the minimum PRB number which meets the condition that the UCI code rate is less than or equal to the maximum code rate of the third PUCCH, the second target PRB number is less than or equal to the PRB number configured by the third PUCCH, and when the third PUCCH is in PUCCH format 2 or PUCCH format 3, the PRB number configured by the third PUCCH is configured by RRC. When the third PUCCH is in PUCCH format 4, the PRB number of the third PUCCH is 1, and the step is mainly applied to the third PUCCH in format 2 or format 3. And if the code rate of the UCI is still greater than the maximum code rate of the third PUCCH when the PRB number configured by the third PUCCH is utilized, the second target PRB is equal to the PRB number configured by the third PUCCH.

S508: and transmitting the UCI by using the second target PRB number.

In an embodiment, if the second target number of PRBs is equal to the number of PRBs configured in the third PUCCH and the code rate of the UCI is greater than the maximum code rate of the third PUCCH, discarding part or all of CSI, so that the code rate of the remaining part of the UCI is less than or equal to the maximum code rate of the third PUCCH.

Therefore, the embodiment of the invention can determine the PUCI multiplexed on which PUCCH resource and determine the number of PRBs based on the load of the UCI, thereby avoiding the reduction of transmission reliability caused by the fact that the code rate of the UCI exceeds the maximum code rate of the third PUCCH, and improving the reliability of UCI transmission.

As shown in fig. 6, an embodiment of the present invention provides a method 600 for transmitting uplink control information, which may be performed by a terminal device, in other words, the method may be performed by software or hardware installed in the terminal device, and the method includes the following steps:

s602: multiplexing UCI on the first PUCCH resource, the second PUCCH resource, or a third PUCCH resource.

This step may also include the following implementation of determining to which PUCCH resource to multiplex UCI.

In one implementation, UCI may be multiplexed onto the third PUCCH resource if the terminal device is configured with multiple resources feeding back SPS HARQ-ACKs. For example, the UE configures multiple downlink SPSs, and configures multiple PUCCH resources for feeding back SPS HARQ-ACK by using AN RRC parameter SPS-PUCCH-AN-List, and at this time, multiplexes UCI to a third PUCCH resource, that is, one of the PUCCH resources configured by the SPS-PUCCH-AN-List.

In another implementation, UCI may be multiplexed onto the second PUCCH resource in case that the terminal device is configured with one resource feeding SPS HARQ-ACK back. For example, the UE does not configure the parameter SPS-PUCCH-AN-List, or the SPS-PUCCH-AN-List configures only one PUCCH resource for feeding back SPS HARQ-ACK, and at this time, UCI is multiplexed onto the second PUCCH resource.

In another implementation, the UE may not desire to configure simultaneous transmission of HARQ-ACK and CSI, i.e. configure the parameter simultaneousHARQ-ACK-CSI, in case the terminal device is configured with one resource for feeding back SPS HARQ-ACK. For example, the UE does not have the configuration parameter SPS-PUCCH-AN-List, or only has one PUCCH resource configured to feed back SPS HARQ-ACK, and at this time, the UE does not expect to configure parameter simultaneousHARQ-ACK-CSI, and when the first PUCCH and the second PUCCH resource overlap, the UE discards the second PUCCH to transmit the first PUCCH.

In another implementation, the multiplexing of the UCI on the first or second PUCCH resource may be determined according to a format of the first PUCCH resource. Specifically, the resources of the PUCCH resources may include a plurality of formats, for example, a PUCCH format 0/1/2/3/4 may be configured.

In another implementation, in a case that a format of the first PUCCH resource is a first preset format, UCI may be multiplexed onto the second PUCCH resource. In a case where the format of the first PUCCH resource is a second preset format, UCI may be multiplexed onto the first PUCCH resource. The first preset format may be a PUCCH format 0/1, and the second preset format may be a PUCCH format 2/3/4.

In another implementation, multiplexing UCI on the first or third PUCCH resources may be determined according to a format of the first PUCCH resource. Specifically, the resources of the PUCCH resources may include a plurality of formats, for example, a PUCCH format 0/1/2/3/4 may be configured.

In another implementation, in a case that a format of the first PUCCH resource is a first preset format, UCI may be multiplexed onto the second PUCCH resource. In a case where the format of the first PUCCH resource is a second preset format, UCI may be multiplexed onto the third PUCCH resource. The first preset format may be a PUCCH format 0/1, and the second preset format may be a PUCCH format 2/3/4.

In another implementation manner, under the condition that the number of the HARQ-ACK bits is less than or equal to a preset value N, multiplexing UCI to the second PUCCH resource; and multiplexing UCI to the third PUCCH resource under the condition that the number of the ARQ-ACK bits is larger than the preset value. Wherein the preset value may be equal to 1 or equal to 2, i.e. N ═ 1 or 2.

On this basis, in the case of multiplexing UCI to the first PUCCH resource or the second PUCCH resource, this embodiment may further include the step of transmitting UCI as described in step S304 in the embodiment of fig. 3. In the case of multiplexing UCI to the first PUCCH resource, the present embodiment may further include the step of transmitting UCI as described in steps S404 to S406 in the embodiment of fig. 4. In the case of multiplexing UCI to the third PUCCH resource, this embodiment may further include the step of transmitting UCI as described in steps S504 to S508 in the embodiment of fig. 5. For the sake of brevity, no further description is provided.

Therefore, the embodiment of the invention can determine the PUCCH resource on which the UCI is multiplexed and determine the number of PRBs (physical resource blocks) for UCI transmission, can avoid the code rate of the UCI from exceeding the maximum code rate of the first PUCCH or the second PUCCH, and improves the reliability of UCI transmission.

A specific illustrative example is set forth below as an illustration.

In this example, the UE configures and activates multiple DL SPS, and configures multiple (e.g., 4) PUCCH resources for feedback HARQ-ACK for SPS PDSCH, e.g., configured by parameter SPS-PUCCH-AN-List. Wherein, the range of the number of bits used for carrying by the first PUCCH is [1,2], the range of the number of bits used for carrying by the second PUCCH is [3, N2], the range of the number of bits used for carrying by the third PUCCH is [ N2+1, N3], and the range of the number of bits used for carrying by the fourth PUCCH is [ N3+1,1706 ]. Where N2, N3 is RRC configuration, e.g., N2-32, N3-256.

In a certain slot/sub-slot, the UE needs to feed back HARQ-ACKs of a plurality of SPS PDSCHs on one PUCCH, and the UE determines which PUCCH resource to use for feeding back HARQ-ACK according to a bit range carried by 4 feedback SPS PDSCH HARQ-ACK PUCCH configured by RRC. HARQ-ACK PUCCH, CSI PUCCH (which may be P-CSI or SP-CSI, and may be a CSI PUCCH resource or a plurality of CSI multiplexed PUCCH resources), and SRPUCCH are overlapped, wherein SR may be positive (positive) SR or negative (negative) SR, and may be k SR configurations (in this case, log needs to be multiplexed)₂(K+1)bit SR)。

And if the UE only needs to feed back 2-bit HARQ-ACK of 2 PDSCHs, the UE determines to feed back the HARQ-ACK by using the first PUCCH resource. The UE multiplexes the 2-bit HARQ-ACK and the 2-bit SR (log2(M +1), wherein M represents the overlapped SR configuration number) on the CSI PUCCH resource for transmission, and uses the PRB number configured by the PUCCH resource RRC.

In one implementation, if the code rate of the multiplexed UCI exceeds the maximum code rate of the CSI PUCCH, the UE discards part or all of the CSI reports according to a certain rule, so that the code rate of the remaining UCI after discarding does not exceed the maximum code rate.

If the UE needs to feed back HARQ-ACKs larger than 2 PDSCHs, e.g., 5, the UE determines to feed back 5-bit HARQ-ACK using the second PUCCH.

In one implementation, the UE determines one PUCCH resource, for example, a third PUCCH resource, among the four configured PUCCH resources for feedback SPS PDSCH HARQ-ACK according to the HARQ-ACK bit number (5 bits), the SR bit number (2 bits), and the CSI bit number (assuming 40 bits). If the determined PUCCH resource is in the format 2/3, the UE has the bit number (5+2+40+ O) according to UCI in the third PUCCH resource_CRC) And determining the number of used PRBs according to the maximum code rate corresponding to the third PUCCH, so that the multiplexed code rate does not exceed the maximum code rate corresponding to the third PUCCH. And if the maximum code rate is still exceeded when the number of PRBs configured by the third PUCCH is used, discarding part or all of the CSI reports according to a certain rule. Or if the maximum code rate is still exceeded when the PRB number configured by the third PUCCH is used, the HARQ-ACK, the SR and the CSI are transmitted by using the PRB number configured by the third PUCCH.

In another implementation, the UE determines one PUCCH resource, for example, a third PUCCH resource, among the four configured PUCCH resources for feedback SPS PDSCH HARQ-ACK according to the HARQ-ACK bit number (2/5 bits), the SR bit number (2 bits), and the CSI bit number (assuming 40 bits). If the determined PUCCH resource is in the format 2/3, the number of bits according to UCI within the third PUCCH resource of the UE (2/5+2+40+ O)_CRC) And determining the number of used PRBs (physical resource blocks) by the maximum code rate, so that the code rate after multiplexing does not exceed the maximum code rate corresponding to the third PUCCH. And if the maximum code rate is still exceeded when the number of PRBs configured by the third PUCCH is used, discarding part or all of the CSI reports according to a certain rule. Or if the maximum code rate is still exceeded when the PRB number configured by the third PUCCH is used, the HARQ-ACK, the SR and the CSI are transmitted by using the PRB number configured by the third PUCCH.

The above describes in detail a transmission method of uplink control information according to an embodiment of the present invention with reference to fig. 1 to 6. A terminal device according to an embodiment of the present invention will be described in detail below with reference to fig. 7.
