Description

Information transmission method, device and equipment

Technical Field

The present application relates to the field of communications, and in particular, to an information transmission method, apparatus, and device.

Background

In a Time Division Duplex (TDD) mode of a New Radio (NR), one slot includes a plurality of Orthogonal Frequency Division Multiplexing (OFDM) symbols, and is divided into: downlink symbols (downlink), flexible symbols (flexible), and uplink symbols (uplink). The downlink symbols are used for downlink transmission, the uplink symbols are used for uplink transmission, and the flexible symbols can be used for uplink transmission and downlink transmission. The base station may configure, through Radio Resource Control (RRC) signaling, the number of semi-static downlink/flexible/uplink symbols included in each timeslot within a period time for the electronic device.

When downlink data transmission is performed, a Semi-Persistent Scheduling (SPS) Scheduling manner may be used. The SPS scheduling information may be carried by a Physical Downlink Control Channel (PDCCH), and the Downlink data scheduled by the SPS scheduling information may be carried by a Physical Downlink Shared Channel (PDSCH). After receiving downlink data on the PDSCH, the electronic device needs to use a Physical Uplink Control Channel (PUCCH) resource indicated by the SPS scheduling information to report Hybrid Automatic Retransmission Request (HARQ) -Acknowledgement (ACK) information. However, there is a possibility that the PUCCH resource indicated by the SPS scheduling information overlaps with the downlink symbol of the slot in which the PUCCH resource is located, and thus the electronic device cannot transmit HARQ-ACK information to the network side device using the PUCCH resource indicated by the SPS scheduling information.

Detailed Description

The terminology used in the description of the embodiments section of the present application is for the purpose of describing particular embodiments of the present application only and is not intended to be limiting of the present application.

In the NR TDD mode, one slot includes several OFDM symbols, for example, in normal CP, one slot includes 14 OFDM symbols, and in extended CP, one slot typically includes 12 OFDM symbols. An OFDM symbol included in one slot may be divided into: downlink symbols (downlink), flexible symbols (flexible), and uplink symbols (uplink). The downlink symbols are used for downlink transmission, the uplink symbols are used for uplink transmission, and the flexible symbols can be used for uplink transmission and downlink transmission. The base station may configure the number of downlink symbols, flexible symbols, and uplink symbols included in each slot within a cycle time for the electronic device through RRC signaling.

When downlink data transmission is carried out, a dynamic scheduling mode and an SPS scheduling mode are included. In the SPS scheduling mode, the network side device issues Downlink Control Information (DCI) carrying SPS scheduling Information to the electronic device, where the DCI is carried on a PDCCH, and then the network side device transmits Downlink data scheduled by the SPS scheduling Information on a PDSCH. After receiving downlink data on the PDSCH, the electronic device sends Uplink Control Information (UCI) on the PUCCH resource indicated by the SPS scheduling Information in order to report to the network side device whether the downlink data on the PDSCH is decoded correctly, where the UCI carries HARQ-ACK Information for recording whether the downlink data is decoded correctly. Specifically, if the decoding is correct, the HARQ-ACK information is ACK, and if the decoding is incorrect, the HARQ-ACK information is Negative Acknowledgement (NACK).

In addition, for the HARQ-ACK information, in order to implement fast feedback of the high-priority downlink service, the network side device may further configure or indicate a transmission priority of the HARQ-ACK information corresponding to the downlink service, where the HARQ-ACK information includes the HARQ-ACK information with the high priority and the HARQ-ACK information with the low priority. The high priority HARQ-ACK information and the low priority HARQ-ACK information may be fed back in the same slot.

At present, a PUCCH resource indicated by SPS scheduling information may overlap with a downlink symbol of a slot in which the PUCCH resource is located, so that the electronic device cannot transmit HARQ-ACK information to the network side device using the PUCCH resource indicated by SPS scheduling information.

The application provides an information transmission method, an information transmission device and electronic equipment, which can realize the transmission of HARQ-ACK information when PUCCH resources indicated by network side equipment and used for transmitting the HARQ-ACK information are invalid.

Wireless communication systems to which the present application may be applied may include, but are not limited to: new Radio (NR) systems. For example, the present application may be applied in a high-reliability low latency communication (URLLC) scenario of an NR system. The electronic devices described herein may include, but are not limited to: handheld devices, vehicle-mounted devices, wearable devices, and the like having wireless communication functions. The network side device described in this application may be a base station, and in different communication systems, implementation types of the base station may have differences, and the application is not limited thereto, for example, in an NR communication system, the network side device may be a next generation base station (gNB).

Fig. 1 is a flowchart of an embodiment of an information transmission method of the present application, and as shown in fig. 1, the method may include:

step 101: if the first PUCCH resource is overlapped with a first symbol of a time slot in which the first PUCCH resource is located, determining a first time slot from the time slot in which the first PUCCH resource is located, wherein the first time slot is a time slot in which a second symbol is located; the first symbol is a symbol for downlink transmission, and the second symbol is a symbol for uplink transmission; the first PUCCH resource is a PUCCH resource used for transmitting HARQ-ACK information and indicated by the network side equipment.

In one possible implementation, the first symbol may be a downlink symbol; the second symbol may be an uplink symbol, or an uplink symbol and a flexible symbol.

In another possible implementation, the first symbol may be a downlink symbol and a flexible symbol, and the second symbol may be an uplink symbol.

In yet another possible implementation, the first symbol may be a downlink symbol and a flexible symbol configured for downlink transmission, and the second symbol may be an uplink symbol and a flexible symbol configured for uplink transmission.

Step 102: selecting a second PUCCH resource from a first resource set and/or a second resource set of a first slot; the first resource set is a set of PUCCH resources configured for SPS, and the second resource set is a set of PUCCH resources configured for dynamic scheduling; the second PUCCH resource overlaps with the second symbol.

The first resource set and the second resource set may be configured for the electronic device by the network side device through RRC signaling. Optionally, the first set of resources may include PUCCH resources configured by the sps-PUCCH-AN-List-r16 parameter; the second set of resources may include PUCCH resources configured by a PUCCH-ResourceSet parameter.

Wherein, if the HARQ-ACK information is prioritized, the second set of resources may include: a third resource set configured for high priority HARQ-ACK information and a fourth resource set configured for low priority HARQ-ACK information, in this case, this step may include: the second PUCCH resource is selected from the first set of resources, and/or the second set of resources, and/or the fourth set of resources of the first slot.

Step 103: and transmitting the HARQ-ACK information on the second PUCCH resource.

Wherein, the HARQ-ACK information may be carried in the UCI for transmission.

In the method shown in fig. 1, if there is an overlap between a first PUCCH resource and a first symbol of a slot in which the first PUCCH resource is located, a first slot is searched from the slot in which the first PUCCH resource is located, a second PUCCH resource is selected from a first resource set and/or a second resource set of the first slot, and HARQ-ACK information is sent on the second PUCCH resource, so that transmission of HARQ-ACK information is achieved under the condition that the PUCCH resource indicated by DCI by a network side device is invalid, transmission delay of the HARQ-ACK information is reduced, and reliability of transmission of the HARQ-ACK information is improved. .

The information transmission method of the present application is described in more detail by way of example below.

Fig. 2 is a flowchart of another embodiment of the information transmission method of the present application, and as shown in fig. 2, the method may include:

step 201: the electronic device determines a first PUCCH resource according to the received DCI.

The DCI may carry SPS scheduling information of the PDSCH, and may also indicate a first PUCCH resource used by HARQ-ACK information of the SPS PDSCH, where the first PUCCH resource indicated by the DCI is generally one PUCCH resource in a first resource set configured for SPS by the network side device. Specifically, a PUCCH Resource Indicator (PRI) field of the DCI may be used to indicate the first PUCCH resource.

Step 202: the electronic equipment judges that the first PUCCH resource is overlapped with a first symbol of the time slot where the first PUCCH resource is located, and determines the first time slot from the time slot where the first PUCCH resource is located, wherein the first time slot is a time slot with a second symbol.

Specifically, the electronic device may sequentially determine whether a second symbol exists in each slot from the slot where the first PUCCH resource is located until it is determined that a second symbol exists in a certain slot, and use the slot where the second symbol exists as the first slot. For example, if the slot in which the first PUCCH resource is located has the second symbol, the slot in which the first PUCCH resource is located is taken as the first slot, otherwise, if the next slot of the slot in which the first PUCCH resource is located has the second symbol, the next slot of the slot in which the first PUCCH resource is located is taken as the first slot, and so on until the first slot is determined.

Step 203: the electronic equipment screens out effective PUCCH resources from the first resource set and/or the second resource set of the first time slot to obtain a first alternative resource set. The valid PUCCH resource is a PUCCH resource that overlaps with the second symbol and satisfies the first condition.

Specifically, the electronic device may remove PUCCH resources overlapping with the first symbol from the first resource set and/or the second resource set of the first slot, and remove PUCCH resources that do not satisfy the first condition, so that the remaining PUCCH resources in the first resource set and/or the second resource set are valid PUCCH resources.

The processing duration of the PDSCH refers to: a time period from when the electronic device receives the last symbol of the PDSCH to the earliest time when the electronic device transmits HARQ-ACK information. The PDSCH typically has a minimum processing duration. Based on this, the PUCCH resources satisfying the first condition mean: and the time interval between the starting symbol of the PUCCH resource and the last symbol received by the electronic equipment on the PDSCH is more than or equal to the minimum processing duration of the PDSCH.

Step 204: the electronic device selects a second PUCCH resource from the first set of alternative resources.

However, considering the transmission timeliness of the HARQ-ACK, it is preferable to select a PUCCH resource relatively earlier in the time domain in the first candidate resource set as the second PUCCH resource, for example, the first PUCCH resource in the time domain may be selected as the second PUCCH resource so as to maximize the transmission timeliness of the HARQ-ACK and minimize the transmission delay. The first PUCCH resource may be a PUCCH resource with the earliest starting symbol, or a PUCCH resource with the earliest terminating symbol, or the like. At this time, the step may include: and selecting a first PUCCH resource on a time domain from PUCCH resources included in the first alternative resource set, wherein the first PUCCH resource is the PUCCH resource with the earliest starting symbol or the PUCCH resource with the earliest terminating symbol.

If the first PUCCH resources selected in the above manner are at least two, a PUCCH resource satisfying one of the following conditions may be further selected from the selected first PUCCH resources as a second PUCCH resource: a PUCCH resource having a maximum number of symbols, or a PUCCH resource having a maximum number of Physical Resource Blocks (PRBs), or a PUCCH resource having a maximum product of the number of symbols and the number of PRBs, or a PUCCH resource having a minimum PUCCH resource index.

For example, referring to fig. 3A, assuming that the first slot includes 14 symbols, symbols 0 to 5 are configured as downlink symbols, symbols 6 to 7 are configured as flexible symbols, symbols 8 to 13 are configured as uplink symbols, and 4 PUCCH resources including PUCCH0 to PUCCH3 are included in the first set of alternative resources, then,

if the first PUCCH resource is the PUCCH resource with the earliest starting symbol, two PUCCH resources, namely PUCCH1 and PUCCH2, may be selected, and then the PUCCH resource with the largest symbol number or the largest PRB number, that is, PUCCH1, may be selected as the second PUCCH resource, or the PUCCH resource with the smallest PUCCH resource index, that is, PUCCH1, may be selected as the second PUCCH resource;

if the first PUCCH resource is the PUCCH resource with the earliest end symbol, two PUCCH resources, namely PUCCH2 and PUCCH3, may be selected, and then the PUCCH resource with the largest symbol number or the largest PRB number, that is, PUCCH2, may be selected as the second PUCCH resource, or the PUCCH resource with the smallest PUCCH resource index, that is, PUCCH2, may be selected as the second PUCCH resource.

If there is no screened valid PUCCH resource in step 203, that is, the first candidate resource set is empty, and thus the second PUCCH resource cannot be selected in step 204, the process may return to step 202 to re-determine the first slot, and step 203 to step 204 are executed again until the second PUCCH resource is selected, and step 205 is executed.

Step 205: the electronic device transmits HARQ-ACK information on the second PUCCH resource.

The method shown in fig. 2 is illustrated by way of example:

referring to fig. 3B, it is assumed that the first slot includes 14 symbols, symbols 0 to 5 are configured as downlink symbols, symbols 6 to 7 are configured as flexible symbols, and symbols 8 to 13 are configured as uplink symbols; the first set of resources includes: the SPS-PUCCH 1-SPS-PUCCH 3 comprises 3 PUCCH resources in total, and the second resource set comprises: 3 PUCCH resources including the PUCCHs 1-3 are provided, and the PUCCH resources in the two resource sets meet the requirement of the first time interval. Then the process of the first step is carried out,

if the first symbol is a downlink symbol, the second symbol is an uplink symbol and a flexible symbol, and the second PUCCH resource is selected from the first set of resources only, then SPS-PUCCH2 and SPS-PUCCH3 may be screened from the first set of resources as valid PUCCH resources since SPS-PUCCH1 overlaps with downlink symbol No. 5; whether the first PUCCH resource is the PUCCH resource with the earliest starting symbol or the PUCCH resource with the earliest terminating symbol, SPS-PUCCH3 may be selected as the first PUCCH resource, that is, the second PUCCH resource. If the first symbol is a downlink symbol and the second symbol is an uplink symbol, and the second PUCCH resource is selected only from the first set of resources, then only SPS-PUCCH2 is the valid PUCCH resource, from which SPS-PUCCH2 may be selected as the first PUCCH resource, i.e., the second PUCCH resource.

If the first symbol is a downlink symbol, the second symbol is an uplink symbol and a flexible symbol, and only the second PUCCH resource is selected from the second resource set, then, since PUCCH3 overlaps with downlink symbol No. 5, PUCCH1 and PUCCH2 may be screened from the second resource set as valid PUCCH resources; regardless of whether the first PUCCH resource is the PUCCH resource with the earliest start symbol or the PUCCH resource with the earliest stop symbol, the PUCCH1 may be selected as the first PUCCH resource, that is, the second PUCCH resource. If the first symbol is a downlink symbol, the second symbol is an uplink symbol, and only the second PUCCH resource is selected from the second set of resources, then only PUCCH2 is a valid PUCCH resource, from which PUCCH2 may be selected as the first PUCCH resource, i.e., the second PUCCH resource.

If the first symbol is a downlink symbol, the second symbol is an uplink symbol and a flexible symbol, and the second PUCCH resource is selected from the first resource set and the second resource set, then: PUCCH1, PUCCH2, SPS-PUCCH2, and SPS-PUCCH3 are valid PUCCH resources, and whether the first PUCCH resource is the PUCCH resource with the earliest starting symbol or the PUCCH resource with the earliest terminating symbol, PUCCH1 may be selected as the first PUCCH resource, that is, the second PUCCH resource. If the first symbol is a downlink symbol and the second symbol is an uplink symbol, and the second PUCCH resource is selected from the first resource set and the second resource set, then: PUCCH2 and SPS-PUCCH2 are valid PUCCH resources, and whether the first PUCCH resource is the PUCCH resource with the earliest starting symbol or the PUCCH resource with the earliest terminating symbol, PUCCH2 may be selected as the first PUCCH resource, that is, the second PUCCH resource.

Other possible implementations of the method shown in fig. 2 are not listed by way of example.

In the method shown in fig. 2, if there is an overlap between the first PUCCH resource and the first symbol of the slot in which the first PUCCH resource is located, the first slot is searched from the slot in which the first PUCCH resource is located, the second PUCCH resource is selected from the first resource set and/or the second resource set of the first slot, and the HARQ-ACK information is sent on the second PUCCH resource, so that transmission of the HARQ-ACK information is achieved under the condition that the PUCCH resource indicated by the DCI by the network side device is invalid, transmission delay of the HARQ-ACK information is reduced, and reliability of transmission of the HARQ-ACK information is improved.

Fig. 4 is a flowchart of another embodiment of the information transmission method of the present application, in fig. 4, an electronic device preferentially selects a second PUCCH resource from a first resource set, and selects the second PUCCH resource from a second resource set when there is no valid PUCCH resource in the first resource set, specifically, steps 203 to 204 in fig. 2 are replaced with the following steps 401 to 402:

step 401: the electronic device selects a second PUCCH resource from the first resource set, and if the second PUCCH resource is selected, performs step 205, and if the second PUCCH resource is not selected, performs step 402.

In this step, the implementation that the electronic device selects the second PUCCH resource from the first resource set may refer to step 203, and first screen out an effective PUCCH resource from the first resource set to obtain an alternative resource set; if a valid PUCCH resource is screened from the first resource set, a second PUCCH resource may be selected from the alternative resource set, and the selection method may refer to the example in step 203; if no valid PUCCH resource is screened from the first set of resources, the electronic device will not be able to select a second PUCCH resource from the first set of resources, and step 402 is executed.

Step 402: the electronic device selects a second PUCCH resource from the second resource set, if the second PUCCH resource is selected, step 205 is executed, and if the second PUCCH resource is not selected, the electronic device returns to step 202 to determine a next first slot.

In this step, the implementation that the electronic device selects the second PUCCH resource from the second resource set may refer to the description in step 301, which is not described herein again.

The method shown in fig. 4 is illustrated by taking fig. 3B as an example:

if the first symbol is a downlink symbol, the second symbol is an uplink symbol and a flexible symbol, and the second PUCCH resource is selected from the first resource set first, then, since the SPS-PUCCH1 overlaps with the downlink symbol No. 5, the SPS-PUCCH2 and the SPS-PUCCH3 can be screened from the first resource set as valid PUCCH resources; whether the first PUCCH resource is the PUCCH resource with the earliest starting symbol or the PUCCH resource with the earliest terminating symbol, SPS-PUCCH3 may be selected as the first PUCCH resource. Since the second PUCCH resource has already been selected from the first set of resources, there is no need to select the second PUCCH resource from the second set of resources.

If the first symbol is a downlink symbol and the second symbol is an uplink symbol, and the second PUCCH resource is selected from the first resource set first, then the SPS-PUCCH2 may be screened from the first resource set as a valid PUCCH resource, and the SPS-PUCCH2 may be selected therefrom as the first PUCCH resource.

In the method shown in fig. 4, if there is an overlap between the first PUCCH resource and the first symbol of the slot in which the first PUCCH resource is located, the first slot is searched from the slot in which the first PUCCH resource is located, the second PUCCH resource is selected from the first resource set of the first slot first, if the second PUCCH resource cannot be selected from the first resource set, the second PUCCH resource is selected from the second resource set, and the HARQ-ACK information is sent on the finally selected second PUCCH resource, so that the transmission of the HARQ-ACK information is realized under the condition that the PUCCH resource indicated by the DCI by the network side device is invalid, the transmission delay of the HARQ-ACK information is reduced, and the reliability of the transmission of the HARQ-ACK information is improved.

The method shown in fig. 2 may be particularly applicable to an SPS scheduling scenario in which HARQ-ACK information does not have a priority, and if the HARQ-ACK information has a priority, the network side device may configure a third resource set for the HARQ-ACK information with a high priority and configure a fourth resource set for the HARQ-ACK information with a low priority, where the third resource set and the fourth resource set respectively include a plurality of PUCCH resources. At this time, the process of the present invention,

if several HARQ-ACK information with high priority are transmitted through the same PUCCH resource, that is, the DCI received by the electronic device in step 201 indicates that several HARQ-ACK information with high priority are transmitted through the first PUCCH resource, in this case, step 203 may include: and the electronic equipment screens out effective PUCCH resources from the first resource set and/or the third resource set of the first time slot to obtain a first alternative resource set.

If the plurality of HARQ-ACK information with low priority are transmitted through the same PUCCH resource, that is, the DCI received by the electronic device in step 201 indicates that the plurality of HARQ-ACK information with low priority are transmitted through the first PUCCH resource, at this time, step 203 may include: the electronic equipment screens out effective PUCCH resources from the first resource set and/or the fourth resource set of the first time slot to obtain a first alternative resource set.

The above specific implementation can refer to the description in step 203, and the difference is only that the resource set for screening the valid PUCCH resources changes.

The following examples are given for illustration.

Referring to fig. 5, it is assumed that the first slot includes 14 symbols, symbols 0 to 5 are configured as downlink symbols, symbols 6 to 7 are configured as flexible symbols, and symbols 8 to 13 are configured as uplink symbols; the first set of resources includes: the SPS-PUCCH 1-SPS-PUCCH 3 comprises 3 PUCCH resources in total, and the third resource set comprises: 2 HP PUCCH1 and HP PUCCH2 are shared, and the fourth resource set includes: the LP PUCCH1 has 1 PUCCH resource, and the PUCCH resources in the three resource sets all satisfy the first time interval requirement. Then the process of the first step is carried out,

if the first symbol is a downlink symbol, the second symbol is an uplink symbol and a flexible symbol, and the second PUCCH resource is selected from the first resource set and the third resource set, then: the HP PUCCH1, the HP PUCCH2, the SPS-PUCCH2 and the SPS-PUCCH3 are valid PUCCH resources, and regardless of whether the first PUCCH resource is the PUCCH resource with the earliest starting symbol or the PUCCH resource with the earliest terminating symbol, the HP PUCCH1 can be selected as the first PUCCH resource, that is, the second PUCCH resource. If the first symbol is a downlink symbol and the second symbol is an uplink symbol, and the second PUCCH resource is selected from the first resource set and the third resource set, then: the HP PUCCH2 and the SPS-PUCCH2 are valid PUCCH resources, and regardless of whether the first PUCCH resource is the PUCCH resource with the earliest starting symbol or the PUCCH resource with the earliest terminating symbol, the HP PUCCH2 may be selected as the first PUCCH resource, that is, the second PUCCH resource.

If the first symbol is a downlink symbol, the second symbol is an uplink symbol and a flexible symbol, and the second PUCCH resource is selected from the first resource set and the fourth resource set, then: the LP PUCCH1, SPS-PUCCH2, and SPS-PUCCH3 are valid PUCCH resources, and if the first PUCCH resource is the PUCCH resource with the earliest starting symbol, the LP PUCCH1 may be selected as the first PUCCH resource, that is, the second PUCCH resource. If the first symbol is a downlink symbol and the second symbol is an uplink symbol, and the second PUCCH resource is selected from the first resource set and the third resource set, then: the SPS-PUCCH2 is a valid PUCCH resource, and whether the first PUCCH resource is the PUCCH resource with the earliest starting symbol or the PUCCH resource with the earliest terminating symbol, the SPS-PUCCH2 may be selected as the first PUCCH resource, that is, the second PUCCH resource.

If the first symbol is a downlink symbol, the second symbol is an uplink symbol and a flexible symbol, and the second PUCCH resource is selected from the first resource set, the third resource set, and the fourth resource set, then: HP PUCCH1, HP PUCCH2, LP PUCCH1, SPS-PUCCH2, and SPS-PUCCH3 are valid PUCCH resources, and if the first PUCCH resource is a PUCCH resource with the earliest starting symbol, it may be selected from: two PUCCH resources, HP PUCCH1 and LP PUCCH1, and a PUCCH resource having the largest symbol number, for example, LP PUCCH1 may be selected as the second PUCCH resource. If the first symbol is a downlink symbol and the second symbol is an uplink symbol, and the second PUCCH resource is selected from the first resource set, the third resource set, and the fourth resource set, then: the HP PUCCH2 and the SPS-PUCCH2 are valid PUCCH resources, and regardless of whether the first PUCCH resource is the PUCCH resource with the earliest starting symbol or the PUCCH resource with the earliest terminating symbol, the HP PUCCH2 may be selected as the first PUCCH resource, that is, the second PUCCH resource.

In the method shown in this embodiment, under the condition that the HARQ-ACK information has a priority, when the PUCCH resource indicated by DCI by the network side device is invalid, the HARQ-ACK information is transmitted in time, so that the transmission delay of the HARQ-ACK information is reduced, and the reliability of HARQ-ACK information transmission is improved.

The method shown in fig. 4 may be particularly applicable to an SPS scheduling scenario in which HARQ-ACK information does not have priority, and if HARQ-ACK information has priority, the network side device configures a third resource set for HARQ-ACK information with high priority and configures a fourth resource set for HARQ-ACK information with low priority, where:

in an embodiment, if a plurality of high priority HARQ-ACK information are transmitted through the same PUCCH resource, that is, the DCI received by the electronic device in step 201 indicates that a plurality of high priority HARQ-ACK information are transmitted through the first PUCCH resource, at this time, the second resource set in step 402 may be replaced with the third resource set. The specific implementation of this embodiment may refer to the description of the embodiment shown in fig. 4, and redundant description is omitted here. The following is illustrated by way of example in FIG. 5: if the first symbol is a downlink symbol, the second symbol is an uplink symbol and a flexible symbol, and the second PUCCH resource is selected from the first resource set and the third resource set, then: SPS-PUCCH2 and SPS-PUCCH3 are valid PUCCH resources, and whether the first PUCCH resource is the PUCCH resource with the earliest starting symbol or the PUCCH resource with the earliest terminating symbol, SPS-PUCCH3 may be selected as the first PUCCH resource, that is, the second PUCCH resource. If the first symbol is a downlink symbol and the second symbol is an uplink symbol, and the second PUCCH resource is selected from the first resource set and the third resource set, then the first PUCCH resource may be selected from the first resource set: the SPS-PUCCH2 is a valid PUCCH resource, and whether the first PUCCH resource is a PUCCH resource with an earliest starting symbol or a PUCCH resource with an earliest terminating symbol, the SPS-PUCCH2 may be selected as the first PUCCH resource, that is, the second PUCCH resource.

In an embodiment, if a plurality of HARQ-ACK information with low priority are transmitted through the same PUCCH resource, that is, the DCI received by the electronic device in step 201 indicates that a plurality of HARQ-ACK information with low priority are transmitted through the first PUCCH resource, at this time, the second resource set in step 402 may be replaced with the fourth resource set. The specific implementation of this embodiment may refer to the description of the embodiment shown in fig. 4, and redundant description is omitted here. The following is illustrated by way of example in FIG. 5: if the first symbol is a downlink symbol, the second symbol is an uplink symbol and a flexible symbol, and the second PUCCH resource is selected from the first resource set and the fourth resource set, then: SPS-PUCCH2 and SPS-PUCCH3 are valid PUCCH resources, and whether the first PUCCH resource is the PUCCH resource with the earliest starting symbol or the PUCCH resource with the earliest terminating symbol, SPS-PUCCH3 may be selected as the first PUCCH resource, that is, the second PUCCH resource. If the first symbol is a downlink symbol and the second symbol is an uplink symbol, and the second PUCCH resource is selected from the first resource set and the fourth resource set, then the first PUCCH resource may be selected from the first resource set: the SPS-PUCCH2 is a valid PUCCH resource, and whether the first PUCCH resource is the PUCCH resource with the earliest starting symbol or the PUCCH resource with the earliest terminating symbol, the SPS-PUCCH2 may be selected as the first PUCCH resource, that is, the second PUCCH resource.

In an embodiment, if the plurality of HARQ-ACK information with low priority and the plurality of HARQ-ACK information with high priority are both transmitted through the same PUCCH resource, that is, the DCI received by the electronic device in step 201 indicates that the plurality of HARQ-ACK information with low priority and the plurality of HARQ-ACK information with high priority are both transmitted through the first PUCCH resource, at this time, referring to fig. 6, step 402 may be replaced with the following steps 601 to 602:

step 601: the electronic device selects a second PUCCH resource from the third set of resources, and if the second PUCCH resource is selected, performs step 205, and if the second PUCCH resource is not selected, performs step 602.

Step 602: the electronic device selects a second PUCCH resource from the fourth resource set, if the second PUCCH resource is selected, step 205 is executed, and if the second PUCCH resource is not selected, the electronic device returns to step 202 to determine a next first slot.

The implementation of steps 601 to 602 may refer to the description in steps 401 to 402, and the difference is only that the resource set for selecting the second PUCCH resource is different.

The following is illustrated by way of example in FIG. 5: if the first symbol is a downlink symbol, the second symbol is an uplink symbol and a flexible symbol, and the second PUCCH resource is selected from the first resource set, the third resource set, and the fourth resource set, then: SPS-PUCCH2 and SPS-PUCCH3 are valid PUCCH resources, and whether the first PUCCH resource is the PUCCH resource with the earliest starting symbol or the PUCCH resource with the earliest terminating symbol, SPS-PUCCH3 may be selected as the first PUCCH resource, that is, the second PUCCH resource. If the first symbol is a downlink symbol and the second symbol is an uplink symbol, and the second PUCCH resource is selected from the first resource set, the third resource set, and the fourth resource set, then: the SPS-PUCCH2 is a valid PUCCH resource, and whether the first PUCCH resource is the PUCCH resource with the earliest starting symbol or the PUCCH resource with the earliest terminating symbol, the SPS-PUCCH2 may be selected as the first PUCCH resource, that is, the second PUCCH resource.

In the above embodiment, under the condition that the HARQ-ACK information has the priority, when the PUCCH resource indicated by the DCI by the network side device is invalid, the HARQ-ACK information is transmitted in time, so that the transmission delay of the HARQ-ACK information is reduced, and the reliability of the transmission of the HARQ-ACK information is improved.
