Description

Technical Field

[0001] The present application relates to the field of communications, and in particular to an information transmission method, device and equipment. Background Art

[0002] In the time division duplexing (TDD) mode of the New Radio (NR), a time slot includes several orthogonal frequency division multiplexing (OFDM) symbols, which are divided into: downlink symbols, flexible symbols, and uplink symbols. Downlink symbols are used for downlink transmission, uplink symbols are used for uplink transmission, and flexible symbols can be used for uplink transmission as well as downlink transmission. The base station can configure the number of semi-static downlink / flexible / uplink symbols contained in each time slot within the cycle time for the electronic device through Radio Resource Control (RRC) signaling.

[0003] When performing downlink data transmission, a semi-persistent scheduling (SPS) scheduling method can be used. The SPS scheduling information can be carried by the physical downlink control channel (PDCCH), and the downlink data scheduled by the SPS scheduling information can be carried by the physical downlink shared channel (PDSCH). After the electronic device receives the downlink data on the PDSCH, it needs to use the physical uplink control channel (PUCCH) resources indicated by the SPS scheduling information to report the hybrid automatic retransmission request (HARQ)-confirmation (ACK) information. However, the PUCCH resources indicated by the SPS scheduling information may overlap with the downlink symbols of the time slot where the PUCCH resources are located, resulting in the electronic device being unable to use the PUCCH resources indicated by the SPS scheduling information to send HARQ-ACK information to the network side device.

[0056] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application.

[0057] In the TDD mode of NR, a slot includes several OFDM symbols. For example, under normal CP, a slot includes 14 OFDM symbols, while under extended CP, a slot generally includes 12 OFDM symbols. The OFDM symbols included in a time slot can be divided into: downlink symbols, flexible symbols, and uplink symbols. Downlink symbols are used for downlink transmission, uplink symbols are used for uplink transmission, and flexible symbols can be used for both uplink and downlink transmission. The base station can configure the number of downlink symbols, flexible symbols, and uplink symbols contained in each time slot within the cycle time for the electronic device through RRC signaling.

[0058] When performing downlink data transmission, it includes a dynamic scheduling mode and an SPS scheduling mode. In the SPS scheduling mode, the network side device sends downlink control information (Downlink Control Information, DCI) carrying SPS scheduling information to the electronic device, and the DCI is carried on the PDCCH. After that, the network side device transmits the downlink data scheduled by the SPS scheduling information on the PDSCH. After the electronic device receives the downlink data on the PDSCH, in order to report to the network side device whether the downlink data on the PDSCH is decoded correctly, the uplink control information (Uplink Control Information, UCI) is sent on the PUCCH resource indicated by the SPS scheduling information. The UCI carries HARQ-ACK information to record whether the downlink data is decoded correctly. Specifically, if the decoding is correct, the HARQ-ACK information is ACK, and if the decoding is wrong, the HARQ-ACK information is a negative acknowledgment (NACK).

[0059] In addition, for HARQ-ACK information, in order to achieve rapid feedback of high-priority downlink services, the network-side device can also configure or indicate the transmission priority of the HARQ-ACK information corresponding to the downlink service. At this time, the HARQ-ACK information includes high-priority HARQ-ACK information and low-priority HARQ-ACK information. High-priority HARQ-ACK information and low-priority HARQ-ACK information can be fed back in the same time slot.

[0060] Currently, the PUCCH resources indicated by the SPS scheduling information may overlap with the downlink symbols of the time slot where the PUCCH resources are located, resulting in the electronic device being unable to use the PUCCH resources indicated by the SPS scheduling information to send HARQ-ACK information to the network side device.

[0061] The present application proposes an information transmission method, device and electronic device, which can realize the transmission of HARQ-ACK information when the PUCCH resources for transmitting HARQ-ACK information indicated by the network side device are invalid.

[0062] The wireless communication systems to which the present application can be applied may include, but are not limited to, New Radio (NR) systems. For example, the present application may be applicable to ultra-reliable low latency communications (URLLC) scenarios of NR systems. The electronic devices described in the present application may include, but are not limited to, handheld devices, vehicle-mounted devices, wearable devices, etc. with wireless communication functions. The network side device described in the present application may be a base station. In different communication systems, the implementation type of the base station may be different, which is not limited in the present application. For example, in an NR communication system, the network side device may be a next-generation base station (gNB).

[0063] Figure 1 This is a flow chart of an embodiment of the information transmission method of the present application, such as Figure 1 As shown, the method may include:

[0064] Step 101: If the first PUCCH resource overlaps with the first symbol of the time slot where the first PUCCH resource is located, determine the first time slot starting from the time slot where the first PUCCH resource is located, the first time slot is the time slot in which the second symbol exists; 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 indicated by the network side device for transmitting HARQ-ACK information.

[0065] In a possible implementation manner, the first symbol may be a downlink symbol; the second symbol may be an uplink symbol, or an uplink symbol and a flexible symbol.

[0066] In another possible implementation manner, the first symbol may be a downlink symbol and a flexible symbol, and the second symbol may be an uplink symbol.

[0067] 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.

[0068] Step 102: Select a second PUCCH resource from the first resource set and / or the second resource set in the first time 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.

[0069] 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 resource set may include PUCCH resources configured through the sps-PUCCH-AN-List-r16 parameter; the second resource set may include PUCCH resources configured through the PUCCH-ResourceSet parameter.

[0070] Among them, if the HARQ-ACK information distinguishes priorities, the second resource set 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. At this time, this step may include: selecting a second PUCCH resource from the first resource set of the first time slot, and / or the second resource set, and / or the fourth resource set.

[0071] Step 103: Send HARQ-ACK information on the second PUCCH resource.

[0072] Among them, the HARQ-ACK information can be carried in the UCI for transmission.

[0073] Figure 1 In the method shown, if the first PUCCH resource overlaps with the first symbol of the time slot where the first PUCCH resource is located, the first time slot is searched from the time slot where 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 time slot, and the HARQ-ACK information is sent on the second PUCCH resource, thereby realizing the transmission of HARQ-ACK information when the PUCCH resource indicated by the network side device through the DCI is invalid, reducing the transmission delay of the HARQ-ACK information, and improving the reliability of the HARQ-ACK information transmission. .

[0074] The following is a more specific description of the information transmission method of this application through examples.

[0075] Figure 2 This is a flow chart of another embodiment of the information transmission method of the present application, such as Figure 2 As shown, the method may include:

[0076] Step 201: The electronic device determines a first PUCCH resource according to a received DCI.

[0077] In addition to carrying the SPS scheduling information of the PDSCH, the DCI may also indicate the first PUCCH resource used by the HARQ-ACK information of the SPS PDSCH. The first PUCCH resource indicated by the DCI is generally a PUCCH resource in the first resource set configured by the network side device for the SPS. Specifically, the PUCCH resource indicator (PRI) field of the DCI may be used to indicate the above-mentioned first PUCCH resource.

[0078] Step 202: The electronic device determines that the first PUCCH resource overlaps with the first symbol of the time slot where the first PUCCH resource is located, and determines the first time slot starting from the time slot where the first PUCCH resource is located, where the first time slot is the time slot where the second symbol exists.

[0079] Specifically, the electronic device may start from the time slot where the first PUCCH resource is located, and determine in sequence whether there is a second symbol in each time slot until it is determined that a certain time slot has a second symbol, and the time slot where the second symbol exists is used as the first time slot. For example, if there is a second symbol in the time slot where the first PUCCH resource is located, the time slot where the first PUCCH resource is located is used as the first time slot, otherwise, if there is a second symbol in the next time slot of the time slot where the first PUCCH resource is located, the next time slot of the time slot where the first PUCCH resource is located is used as the first time slot, and so on, until the first time slot is determined.

[0080] Step 203: The electronic device selects valid PUCCH resources from the first resource set and / or the second resource set of the first time slot to obtain a first candidate resource set, wherein the valid PUCCH resources refer to PUCCH resources that overlap with the second symbol and meet the first condition.

[0081] Specifically, the electronic device can remove the PUCCH resources overlapping with the first symbol from the first resource set and / or the second resource set in the first time slot, and remove the PUCCH resources that do not meet the first condition, then the remaining PUCCH resources in the first resource set and / or the second resource set are valid PUCCH resources.

[0082] Among them, the processing duration of PDSCH refers to the duration from the last symbol of PDSCH received by the electronic device to the earliest time when the electronic device sends HARQ-ACK information. PDSCH generally has a minimum processing duration. Based on this, the PUCCH resource that meets the first condition means that the time interval between the starting symbol of the PUCCH resource and the last symbol received by the electronic device on PDSCH is greater than or equal to the minimum processing duration of PDSCH.

[0083] Step 204: The electronic device selects a second PUCCH resource from the first candidate resource set.

[0084] Among them, the electronic device can select any PUCCH resource from the first candidate resource set as the second PUCCH resource. However, considering the transmission timeliness of HARQ-ACK, it is preferred to select a PUCCH resource that is relatively early 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 can be selected as the second PUCCH resource so that the transmission timeliness of HARQ-ACK is the highest and the transmission delay is the lowest. The above-mentioned first PUCCH resource can be the PUCCH resource with the earliest starting symbol, or the PUCCH resource with the earliest ending symbol, etc. At this time, this step may include: selecting the first PUCCH resource in the time domain from the PUCCH resources included in the first candidate resource set, the first PUCCH resource being the PUCCH resource with the earliest starting symbol, or the PUCCH resource with the earliest ending symbol.

[0085] If the first PUCCH resources selected in the above manner are at least two, a PUCCH resource that satisfies one of the following conditions can be further selected from the first PUCCH resources selected as the second PUCCH resource: a PUCCH resource with the largest number of symbols, or a PUCCH resource with the largest number of physical resource blocks (PRBs), or a PUCCH resource with the largest product of the number of symbols and the number of PRBs, or a PUCCH resource with the smallest PUCCH resource index.

[0086] For example, see Figure 3A As shown, assuming that the first time 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 the first candidate resource set includes 4 PUCCH resources including PUCCH0 to PUCCH3, then,

[0087] If the first PUCCH resource is the PUCCH resource with the earliest starting symbol, two PUCCH resources, PUCCH1 and PUCCH2, may be selected, and then, the PUCCH resource with the largest number of symbols or the largest number of PRBs, namely, PUCCH1, may be selected as the second PUCCH resource, or the PUCCH resource with the smallest PUCCH resource index, namely, PUCCH1, may be selected as the second PUCCH resource;

[0088] If the first PUCCH resource is the PUCCH resource with the earliest ending symbol, two PUCCH resources, PUCCH2 and PUCCH3, can be selected. Then, the PUCCH resource with the maximum number of symbols or the maximum number of PRBs, that is, PUCCH2, can be selected as the second PUCCH resource, or the PUCCH resource with the smallest PUCCH resource index, that is, PUCCH2, can be selected as the second PUCCH resource.

[0089] Among them, if no valid PUCCH resources are screened out in step 203, that is, the first candidate resource set is empty, and the second PUCCH resource cannot be selected in step 204, you can return to step 202 to re-determine the first time slot, and execute steps 203 to 204 again until the second PUCCH resource is selected, and execute step 205.

[0090] Step 205: The electronic device transmits HARQ-ACK information on the second PUCCH resource.

[0091] right Figure 2 The method shown is illustrated by example:

[0092] See also Figure 3B As shown, assuming that the first time 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 resource set includes: 3 PUCCH resources SPS-PUCCH1 to SPS-PUCCH3, the second resource set includes: 3 PUCCH resources PUCCH1 to PUCCH3, and the PUCCH resources in the two resource sets meet the first time interval requirement. Then,

[0093] 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 only from the first resource set, then, since SPS-PUCCH1 overlaps with the downlink symbol No. 5, SPS-PUCCH2 and SPS-PUCCH3 can be selected from the first resource set as valid PUCCH resources; regardless of whether the first PUCCH resource is the PUCCH resource with the earliest starting symbol or the PUCCH resource with the earliest ending symbol, SPS-PUCCH3 can 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 the second PUCCH resource is selected only from the first resource set, then only SPS-PUCCH2 is a valid PUCCH resource, and SPS-PUCCH2 can be selected as the first PUCCH resource, that is, the second PUCCH resource.

[0094] 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 the downlink symbol No. 5, PUCCH1 and PUCCH2 can be selected from the second resource set as valid PUCCH resources; regardless of whether the first PUCCH resource is the PUCCH resource with the earliest starting symbol or the PUCCH resource with the earliest ending symbol, PUCCH1 can 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 resource set, then only PUCCH2 is a valid PUCCH resource, and PUCCH2 can be selected as the first PUCCH resource, that is, the second PUCCH resource.

[0095] 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 can be screened out from the first resource set and the second resource set as valid PUCCH resources, regardless of whether the first PUCCH resource is the PUCCH resource with the earliest starting symbol or the PUCCH resource with the earliest ending symbol, PUCCH1 can 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 the second PUCCH resource is selected from the first resource set and the second resource set, then PUCCH2 and SPS-PUCCH2 can be screened out from the first resource set and the second resource set as valid PUCCH resources, regardless of whether the first PUCCH resource is the PUCCH resource with the earliest starting symbol or the PUCCH resource with the earliest ending symbol, PUCCH2 can be selected as the first PUCCH resource, that is, the second PUCCH resource.

[0096] Figure 2 Other possible implementations of the method shown are not listed one by one.

[0097] Figure 2 In the method shown, if the first PUCCH resource overlaps with the first symbol of the time slot where the first PUCCH resource is located, the first time slot is searched starting from the time slot where the first PUCCH resource is located, and the second PUCCH resource is selected from the first resource set and / or the second resource set of the first time slot, and HARQ-ACK information is sent on the second PUCCH resource, thereby realizing the transmission of HARQ-ACK information when the PUCCH resource indicated by the network side device through DCI is invalid, reducing the transmission delay of the HARQ-ACK information and improving the reliability of the HARQ-ACK information transmission.

[0098] Figure 4 This is a flowchart of another embodiment of the information transmission method of the present application. Figure 4 In the embodiment, the electronic device preferentially selects the second PUCCH resource from the first resource set. When there is no valid PUCCH resource in the first resource set, the second PUCCH is selected from the second resource set. Specifically, Figure 2 Steps 203 to 204 in the above are replaced by the following steps 401 to 402:

[0099] Step 401: The electronic device selects a second PUCCH resource from a first resource set. If the second PUCCH resource is selected, execute step 205; if the second PUCCH resource is not selected, execute step 402.

[0100] In this step, the implementation of the electronic device selecting the second PUCCH resource from the first resource set can refer to step 203. First, valid PUCCH resources are screened out from the first resource set to obtain an alternative resource set. If valid PUCCH resources are screened out from the first resource set, then the second PUCCH resource can be selected from the alternative resource set. The selection method can refer to the example in step 203. If no valid PUCCH resources are screened out from the first resource set, the electronic device will not be able to select the second PUCCH resource from the first resource set, and step 402 is executed.

[0101] Step 402: The electronic device selects a second PUCCH resource from the second resource set. If the second PUCCH resource is selected, execute step 205. If the second PUCCH resource is not selected, return to step 202 to determine the next first time slot.

[0102] In this step, the electronic device selects the second PUCCH resource from the second resource set for implementation, which can refer to the description in step 301 and will not be repeated here.

[0103] Still Figure 3B For example Figure 4 The method shown is illustrated by way of example:

[0104] If the first symbol is a downlink symbol, and the second symbol is an uplink symbol and a flexible symbol, the second PUCCH resource is selected from the first resource set first. Since SPS-PUCCH1 overlaps with the downlink symbol No. 5, SPS-PUCCH2 and SPS-PUCCH3 can be selected from the first 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 end symbol, SPS-PUCCH3 can be selected as the first PUCCH resource. Since the second PUCCH resource has been selected from the first resource set, there is no need to select the second PUCCH resource from the second resource set.

[0105] If the first symbol is a downlink symbol and the second symbol is an uplink symbol, the second PUCCH resource is first selected from the first resource set. Then, SPS-PUCCH2 can be screened out from the first resource set as a valid PUCCH resource, and SPS-PUCCH2 can be selected as the first PUCCH resource.

[0106] Figure 4In the method shown, if the first PUCCH resource overlaps with the first symbol of the time slot where the first PUCCH resource is located, the first time slot is searched starting from the time slot where the first PUCCH resource is located, and the second PUCCH resource is first selected from the first resource set of the first time slot. If the second PUCCH resource cannot be selected in the first resource set, the second PUCCH resource is selected from the second resource set, and HARQ-ACK information is sent on the second PUCCH resource finally selected, thereby realizing the transmission of HARQ-ACK information when the PUCCH resource indicated by the network side device through DCI is invalid, reducing the transmission delay of the HARQ-ACK information and improving the reliability of the HARQ-ACK information transmission.

[0107] Above Figure 2 The method shown is particularly applicable to the SPS scheduling scenario where HARQ-ACK information does not have a priority. If HARQ-ACK has a priority, the network side device can configure a third resource set for high-priority HARQ-ACK information and a fourth resource set for low-priority HARQ-ACK information. The third resource set and the fourth resource set each include a number of PUCCH resources. At this time,

[0108] If several 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 several high-priority HARQ-ACK information are transmitted through the first PUCCH resource, at this time, step 203 may include: the electronic device filters out valid PUCCH resources from the first resource set and / or the third resource set in the first time slot to obtain a first alternative resource set.

[0109] If several low-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 several low-priority HARQ-ACK information are transmitted through the first PUCCH resource, then step 203 may include: the electronic device filters out valid PUCCH resources from the first resource set and / or the fourth resource set in the first time slot to obtain a first alternative resource set.

[0110] If several low-priority HARQ-ACK information and several high-priority HARQ-ACK information are all transmitted through the same PUCCH resource, that is, the DCI received by the electronic device in step 201 indicates that several low-priority HARQ-ACK information and several high-priority HARQ-ACK information are all transmitted through the first PUCCH resource, at this time, step 203 may include: the electronic device filters out valid PUCCH resources from the first resource set and / or the third resource set and / or the fourth resource set in the first time slot to obtain a first alternative resource set.

[0111] The above specific implementation may refer to the description in step 203, the only difference being that the resource set for screening valid PUCCH resources is changed.

[0112] The following examples are used to illustrate this.

[0113] See also Figure 5 As shown, assuming that the first time 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 resource set includes: SPS-PUCCH1 to SPS-PUCCH3, a total of 3 PUCCH resources, the third resource set includes: HP PUCCH1, HP PUCCH2, a total of 2 PUCCH resources, the fourth resource set includes: LP PUCCH1, a total of 1 PUCCH resource, and the PUCCH resources in the three resource sets all meet the first time interval requirements. Then,

[0114] 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 it can be screened out from the first resource set and the third resource set that: HPPUCCH1, HP PUCCH2, SPS-PUCCH2 and SPS-PUCCH3 are valid PUCCH resources, regardless of whether the first PUCCH resource is the PUCCH resource with the earliest starting symbol or the PUCCH resource with the earliest ending symbol, HP PUCCH1 can 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 the second PUCCH resource is selected from the first resource set and the third resource set, then it can be screened out from the first resource set and the third resource set that: HP PUCCH2 and SPS-PUCCH2 are valid PUCCH resources, regardless of whether the first PUCCH resource is the PUCCH resource with the earliest starting symbol or the PUCCH resource with the earliest ending symbol, HP PUCCH2 can be selected as the first PUCCH resource, that is, the second PUCCH resource.

[0115] 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 it can be screened out from the first resource set and the fourth resource set: LPPUCCH1, SPS-PUCCH2 and SPS-PUCCH3 are valid PUCCH resources. If the first PUCCH resource is the PUCCH resource with the earliest starting symbol, LP PUCCH1 can 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 the second PUCCH resource is selected from the first resource set and the third resource set, then it can be screened out from the first resource set and the third resource set: SPS-PUCCH2 is a valid PUCCH resource. Regardless of whether the first PUCCH resource is the PUCCH resource with the earliest starting symbol or the PUCCH resource with the earliest ending symbol, SPS-PUCCH2 can be selected as the first PUCCH resource, that is, the second PUCCH resource.

[0116] 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 can be screened out from the first resource set, the third resource set and the fourth resource set as valid PUCCH resources. If the first PUCCH resource is the PUCCH resource with the earliest starting symbol, two PUCCH resources, HPPUCCH1 and LP PUCCH1, can be selected therefrom, and then, for example, the PUCCH resource with the largest number of symbols, such as LP PUCCH1, can 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 it can be screened out from the first resource set, the third resource set and the fourth resource set: HP PUCCH2 and SPS-PUCCH2 are valid PUCCH resources. Regardless of whether the first PUCCH resource is the PUCCH resource with the earliest starting symbol or the PUCCH resource with the earliest ending symbol, HPPUCCH2 can be selected as the first PUCCH resource, that is, the second PUCCH resource.

[0117] In the method shown in this embodiment, when HARQ-ACK information has priority, timely transmission of HARQ-ACK information is achieved when the PUCCH resources indicated by the network side device through DCI are invalid, thereby reducing the transmission delay of HARQ-ACK information and improving the reliability of HARQ-ACK information transmission.

[0118] Above Figure 4 The method shown is particularly applicable to an SPS scheduling scenario where the HARQ-ACK information does not have a priority. If the HARQ-ACK has a priority, the network side device configures a third resource set for the high priority HARQ-ACK information and a fourth resource set for the low priority HARQ-ACK information. At this time:

[0119] In one embodiment, if several high-priority HARQ-ACK information is transmitted through the same PUCCH resource, that is, the DCI received by the electronic device in step 201 indicates that several high-priority HARQ-ACK information is transmitted through the first PUCCH resource, then the second resource set in step 402 can be replaced with the third resource set. The specific implementation of this embodiment can refer to Figure 4 The description of the embodiment shown will not be repeated here. Figure 5 Take an example to illustrate: 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 it can be first screened out from the first resource set: SPS-PUCCH2 and SPS-PUCCH3 are valid PUCCH resources, regardless of whether the first PUCCH resource is the PUCCH resource with the earliest starting symbol or the PUCCH resource with the earliest ending symbol, SPS-PUCCH3 can be selected from it 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 the second PUCCH resource is selected from the first resource set and the third resource set, then it can be first screened out from the first resource set: SPS-PUCCH2 is a valid PUCCH resource, regardless of whether the first PUCCH resource is the PUCCH resource with the earliest starting symbol or the PUCCH resource with the earliest ending symbol, SPS-PUCCH2 can be selected from it as the first PUCCH resource, that is, the second PUCCH resource.

[0120] In one embodiment, if several low-priority HARQ-ACK information is transmitted through the same PUCCH resource, that is, the DCI received by the electronic device in step 201 indicates that several low-priority HARQ-ACK information is transmitted through the first PUCCH resource, then the second resource set in step 402 can be replaced with the fourth resource set. The specific implementation of this embodiment can refer to Figure 4 The description of the embodiment shown will not be repeated here. Figure 5Take an example to illustrate: 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 it can be first screened out from the first resource set: SPS-PUCCH2 and SPS-PUCCH3 are valid PUCCH resources, regardless of whether the first PUCCH resource is the PUCCH resource with the earliest starting symbol or the PUCCH resource with the earliest ending symbol, SPS-PUCCH3 can be selected from it 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 the second PUCCH resource is selected from the first resource set and the fourth resource set, then it can be first screened out from the first resource set: SPS-PUCCH2 is a valid PUCCH resource, regardless of whether the first PUCCH resource is the PUCCH resource with the earliest starting symbol or the PUCCH resource with the earliest ending symbol, SPS-PUCCH2 can be selected from it as the first PUCCH resource, that is, the second PUCCH resource.

[0121] In one embodiment, if several low-priority HARQ-ACK information and several 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 several low-priority HARQ-ACK information and several high-priority HARQ-ACK information are transmitted through the first PUCCH resource, at this time, see Figure 6 As shown, step 402 can be replaced by the following steps 601 to 602:

[0122] Step 601: The electronic device selects a second PUCCH resource from a third resource set. If the second PUCCH resource is selected, execute step 205; if the second PUCCH resource is not selected, execute step 602.

[0123] Step 602: The electronic device selects a second PUCCH resource from the fourth resource set. If the second PUCCH resource is selected, execute step 205. If the second PUCCH resource is not selected, return to step 202 to determine the next first time slot.

[0124] The implementation of steps 601 to 602 may refer to the description of steps 401 to 402, the only difference being that a different resource set is used to select the second PUCCH resource.

[0125] by Figure 5Take an example to illustrate: 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 it can be first screened out from the first resource set: SPS-PUCCH2 and SPS-PUCCH3 are valid PUCCH resources, regardless of whether the first PUCCH resource is the PUCCH resource with the earliest starting symbol or the PUCCH resource with the earliest ending symbol, SPS-PUCCH3 can be selected from it 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 the second PUCCH resource is selected from the first resource set, the third resource set, and the fourth resource set, then it can be first screened out from the first resource set: SPS-PUCCH2 is a valid PUCCH resource, regardless of whether the first PUCCH resource is the PUCCH resource with the earliest starting symbol or the PUCCH resource with the earliest ending symbol, SPS-PUCCH2 can be selected from it as the first PUCCH resource, that is, the second PUCCH resource.

[0126] In the above embodiment, when the HARQ-ACK information has priority, the HARQ-ACK information is transmitted in a timely manner when the PUCCH resource indicated by the network side device through the DCI is invalid, thereby reducing the transmission delay of the HARQ-ACK information and improving the reliability of the HARQ-ACK information transmission.
