Description

Technical Field

[0001] The present invention relates to the field of wireless communication technologies, and in particular, to a timing feedback method, an electronic device, and a storage medium. Background Art

[0002] Currently, an Air To Ground (ATG) feature has been introduced in wireless communication technologies. A base station on the ground will establish a radio link with a Customer Premises Equipment (CPE) on an aircraft, thereby achieving the coverage of a communication network. Considering the particularity of ATG network deployment, the coverage range of ATG is up to 300 kilometers at most. Considering the relatively long coverage range and the demand for downlink services in the ATG scenario, a new Time Division Duplexing (TDD) pattern has been introduced for the ATG scenario. Therefore, it is necessary to determine a scheme for Hybrid Automatic Repeat reQuest (HARQ) feedback and related timing. Currently, in the 3GPP protocol, regarding the feedback timing problem, the number of processes required for HARQ feedback is mainly configured through high-layer signaling, specifically including: the slot offset between the Downlink Control Information (DCI) received by a terminal on the Physical Downlink Control Channel (PDCCH) and its scheduled resources, the slot offset values of the Physical Uplink Control Channel (PUCCH) or Physical Downlink Shared Channel (PDSCH) for feedback of the Physical Downlink Shared Channel (PDSCH) and its corresponding HARQ-ACK information, and the slot offset value between the uplink-scheduled DCI and the Physical Uplink Shared Channel (PUSCH) it schedules, etc. However, in the ATG scenario, since there are 30 downlink slots in the TDD period, the existing value range of the number of processes cannot cover a long-delay and wide-coverage scenario similar to ATG, resulting in the inability to correctly implement timing feedback. Summary of the Invention

[0003] The embodiments of the present application aim to provide a timing feedback method, an electronic device, and a storage medium to solve the timing feedback of HARQ confirmation information in a long-delay and wide-coverage scenario, enhance the timing relationship of HARQ confirmation information, and enhance the communication performance of the ATG scenario.

[0023] It should be understood that the specific implementations described herein are only used to explain the present application and are not used to limit the present application.

[0024] In subsequent descriptions, suffixes such as "module", "component", or "unit" used to represent elements are only for the convenience of explaining the present application, and they have no specific meaning in themselves. Therefore, "module", "component", or "unit" can be used interchangeably.

[0025] With the progress of wireless communication technology, in long-delay and wide-coverage scenarios, such as the ATG scenario, a new TDD pattern is introduced. How to perform HARQ feedback and related timing determination for the new TDD pattern has become an urgent problem to be solved. Since the long-delay and wide-coverage scenario has certain similarities with the Non Terrestrial Network (NTN), some definitions in the NTN can be reused. That is, the HARQ feedback process in the long-delay and wide-coverage scenario can adopt a process similar to the HARQ feedback in the NTN. The feedback timing in the existing HARQ feedback process in the NTN scenario can be determined by the k1 value. Currently, the k1 value can indicate the slot interval between the PDSCH and its HARQ-ACK feedback. Currently, it has a total of 8 values, and its range is from 16 to 31, as shown below:

[0026] DL-DataToUL-ACK-v1700::=SEQUENCE(SIZE(1..8))OF INTEGER(16..31)

[0027] The definition of the k1 value refers to the slot offset value of the PDSCH and the corresponding PUCCH or PUSCH for HARQ-ACK information feedback. According to the existing timing problem of HARQ-ACK, if the PDSCH reception ends in slot n, then the UE can feedback the corresponding HAR-ACK information within n + k1 slots. Here, k1 is the number of slots, which is indicated by the PDSCH-to-HARQ-timing-indicator field in the DCI or provided by the high-layer parameter dl-DataToUL-ACK. As Figure 1 shown, k1 = {34, 33, …, 11, 10}, which has exceeded the definition and range of the k1 value in the existing specification. Due to its value range, the existing k1 value cannot meet the requirements of long-delay wide coverage and cannot be applied to the ATG scenario to solve the timing problem of HARQ feedback. Based on this, the embodiments of this application provide a timing feedback method to realize the determination of HARQ feedback timing in the long-delay wide coverage scenario and ensure the timeliness of HARQ confirmation messages.

[0028] Figure 2 is a flowchart of a timing feedback method provided by the embodiments of this application. The embodiments of this application are applicable to the case of HARQ timing feedback in the ATG scenario. This method can be executed by a timing feedback device, which can be implemented by software and / or hardware methods and is generally integrated in a terminal device. As Figure 2 shown, the method provided by the embodiments of this application specifically includes the following steps:

[0029] Step 110: Obtain the indication information of the timing of the hybrid automatic repeat request acknowledgment message.

[0030] Among them, the hybrid automatic repeat request acknowledgment message can be the acknowledgment information reported by the UE for the reception situation of the PUCCH. The timing can be the specified timing for feedbacking the hybrid automatic repeat request acknowledgment message, and the timing can specifically be a slot. The indication information can be the information indicating the timing, and this indication information can include high-layer parameters or downlink control information.

[0031] In the embodiments of this application, the indication information can be obtained. This indication information can indicate the timing of the hybrid automatic repeat request acknowledgment message, and this indication information can indicate the slot corresponding to the timing by means of indicating the number of timing slots or the relative offset of the timing slots, so as to expand the coverage range of the values indicating the timing.

[0032] Step 120: Feedback the hybrid automatic repeat request acknowledgment message according to the timing.

[0033] In the embodiments of this application, determine the slot corresponding to the timing indicated by the indication information, and the hybrid automatic repeat request acknowledgment message can be feedbacked through the timing.

[0034] In an embodiment of the present application, by obtaining indication information for timing of a Hybrid Automatic Repeat reQuest (HARQ) ACK message and feeding back the HARQ ACK message according to the indicated timing, it is possible to solve the problem of timing feedback of HARQ ACK information in a long-delay and wide-coverage scenario, enhance the timing relationship of HARQ ACK information, and enhance the communication performance in the long-delay and wide-coverage scenario.

[0035] Furthermore, based on the above application embodiment, the indication information includes Downlink Control Information (DCI). The indication information includes 32 values, and the value range of each value is from 0 to 63.

[0036] In an embodiment of the present application, the indication information may specifically include DCI, and the DCI may include dl-DataToUL-ACK, or is indicated by the PDSCH-to-HARQ-timing-indicator field in the DCI. The indication information may have 32 values, and the value range of each value may be from 0 to 63. It can be understood that the value of the indication information may not be 32, and the value range may cover at least 30 downlink time slots in the TDD cycle in the ATG scenario.

[0037] In an exemplary embodiment, taking the indication information including the DL-DataToUL-ACK field of the DCI as an example, this field may specifically be a sequence of size 32, and the value range of each position in the sequence may be 64, specifically 0 - 63. The DL-DataToUL-ACK field may be as follows:

[0038] DL-DataToUL-ACK::=SEQUENCE(SIZE(1..32))OF INTEGER

[0039] In some application embodiments, the indication information includes an indication parameter and a bundling granularity indication parameter. The bundling granularity indication parameter indicates that at least two consecutive time slots share the timing of the HARQ ACK message indicated by the indication parameter.

[0040] Among them, the indication parameter may be a range parameter indicating the feedback timing of the HARQ ACK message, and the bundling granularity indication parameter may indicate the number of time slots for which the indication parameter takes effect. The bundling granularity indication parameter may indicate multiple time slots as a whole, and this whole may share the timing of the HARQ ACK message indicated by one indication parameter. The bundling granularity indication parameter may indicate the time slots for which the indication parameter takes effect.

[0041] In the embodiments of the present application, the indication information may include an indication parameter and a bundling granularity indication parameter. The bundling granularity indication parameter may indicate the time slots to which the indication parameter is applied. For example, if the value of the bundling granularity indication parameter is 2, the indication parameter in the indication information may indicate 2 consecutive time slots, and the timing of the feedback hybrid automatic repeat request acknowledgement message may be determined through the indication parameter for these 2 time slots. Further, in some embodiments, the bundling granularity indication parameter may indicate that multiple non-consecutive time slots are regarded as a whole, and the allocation method of non-consecutive time slots may be indicated in the form of a Bitmap to determine which time slots belong to the same bundling granularity indication parameter. The length of the Bitmap may be the total number D of downlink time slots indicated by the bundling granularity indication parameter, with each bit corresponding to one time slot. By analogy, it is possible to distinguish whether adjacent time slots belong to the same bundling granularity indication parameter through 0 or 1 bits, and the granularity of whether non-consecutive time slots belong to the same bundling granularity indication parameter can also be determined by the value of the bundling granularity indication parameter. For example, the bundling granularity indication parameter may be a parameter sequence, and the consecutive or non-consecutive time slots in this parameter sequence together form a whole, and this whole may share the timing of the feedback hybrid automatic repeat request acknowledgement message indicated by the indication parameter.

[0042] In the above embodiments of the application, according to the timing feedback hybrid automatic repeat request acknowledgement message, it includes:

[0043] Determine the logical AND operation result of the hybrid automatic repeat request acknowledgement messages of at least two consecutive time slots indicated by the bundling granularity indication parameter, and feedback the logical AND operation result according to the downlink time slots corresponding to the timing.

[0044] In the embodiments of the present application, the bundling granularity indication parameter may indicate multiple consecutive time slots. It is possible to determine the hybrid automatic repeat request messages of these consecutive time slots, perform a logical AND operation on these hybrid automatic repeat request messages, and feedback the operation result through the uplink time slots corresponding to the indication parameter, so as to realize that multiple consecutive time slots share the timing indicated by the same indication parameter.

[0045] In some other embodiments of the application, according to the timing feedback hybrid automatic repeat request acknowledgement message, it includes:

[0046] Determine the acknowledgement feedback sequence corresponding to the hybrid automatic repeat request acknowledgement messages of at least two consecutive time slots indicated by the bundling granularity indication parameter, and feedback the acknowledgement feedback sequence according to the downlink time slots corresponding to the timing.

[0047] Among them, the acknowledgment feedback sequence may be a sequence for feedbacking multiple Hybrid Automatic Repeat reQuest (HARQ) acknowledgment messages. The acknowledgment feedback sequence may include multiple elements, and the value of each element may correspond to an HARQ acknowledgment message. The acknowledgment feedback sequence may correspond to the HARQ acknowledgment messages of multiple consecutive time slots indicated by the bundling granularity indication parameter. It can be understood that the position of each element in the acknowledgment feedback sequence may be the same as the position of the corresponding time slot in the multiple consecutive time slots indicated by the bundling granularity indication parameter.

[0048] In an embodiment of the present application, the multiple time slots corresponding to a bundling granularity indication parameter may be determined respectively, and the HARQ acknowledgment messages of the multiple time slots corresponding to the bundling granularity indication parameter may be obtained. The HARQ acknowledgment messages may be formed into an acknowledgment feedback sequence, and the acknowledgment feedback sequence may be fed back according to the timing corresponding to the indication parameter.

[0049] Further, based on the above embodiment of the application, the value of the bundling granularity indication parameter is determined by at least one of the following:

[0050] Downlink control information indication; configured according to radio resource control information and activated based on downlink control information; configured according to radio resource control information and activated based on a Medium Access Control (MAC) control element.

[0051] In an embodiment of the present application, the value of the bundling granularity indication parameter may be indicated by downlink control information; or, one or more values may be configured through radio resource control information (RRC), and the configured values may be activated by downlink control information. When the bundling granularity indication parameter is activated by downlink control information, multiple time slots indicated by the bundling granularity indication parameter may share one indication parameter; or, the value of the bundling granularity indication parameter may be configured through radio resource control information, and the configured value of the bundling granularity indication parameter may be activated by a MAC control element (MAC CE). When the bundling granularity indication parameter is activated, multiple time slots indicated by the bundling granularity indication parameter may share one indication parameter.

[0052] In an exemplary implementation manner, the timing of the HARQ acknowledgment message may be indicated by k1 and k1 bundling, see Figure 3, multiple consecutive time slots can be regarded as a whole, that is, bundling. The time slots within the same bundling follow a k1 value. The specific bundling is indicated by higher layer signaling and / or DCI. A reasonable k1 value can be defined by higher layer parameters for each bundling. Regarding the size of the bundling value, it is advisable to consider feeding back HARQ-ACK information on each U time slot as much as possible, and the size of the bundling value is not restricted. Taking Figure 3 as an example, in the ATG scenario, 30 D time slots and 6 U time slots are shared, and the size of the bundling value is 5, that is, each time slot bundling should contain 5 D time slots. In Figure 3 , every 5 downlink time slots can be regarded as a bundling, and a k1 value is used to feed back on the U time slot. For example, k1 = {30, 25, 20, 15, 10, 5}, and the timing problem of HARQ-ACK can be solved through the k1 value.

[0053] Based on the above application embodiments, referring to Figure 3 , for the HARQ-ACK or HARQ-NACK of the downlink time slots within the same bundling, logical AND operation can be performed, and only the operation result of the logical AND operation can be fed back on the uplink time slot corresponding to the k1 value.

[0054] In some other application embodiments, referring to Figure 3 , the HARQ-ACK or HARQ-NACK of the downlink time slots within the same bundling are respectively fed back on the corresponding uplink time slots. As above, at this time, the UE should feed back a 0, 1 sequence on the corresponding uplink time slot to correspond to the HARQ-ACK or HARQ-NACK information of each downlink time slot.

[0055] Based on the above application embodiments, the feedback timing of the HARQ confirmation message in the ATG scenario can be determined through k1 bundling and k1, and the value of the bundling can be indicated by DCI or MAC CE.

[0056] In some application embodiments, the value of the bundling can be configured by RRC and activated by DCI.

[0057] For example, RRC can configure the value of the bundling in the following way:

[0058]

[0059] In the embodiments of the present application, the value of the bundling size can be allocated through the downlink time slot and the uplink time slot. The result of taking the remainder of the downlink time slot divided by the uplink time slot can be used as the value of the bundling size.

[0060] DCI activation: It can be activated through the ACK bundling size indicator. When the high-layer instruction ack-BundlingType is set to "Bundling", it can be indicated by a 1-bit ACK bundling size indicator to activate the value of the bundling size.

[0061] In some other embodiments of the application, the value of bundling can be configured through RRC and activated by MAC CE;

[0062] For example, RRC can configure the value of bundling in the following way:

[0063]

[0064] In the embodiments of the present application, the value of the bundling size can be allocated through the downlink time slot and the uplink time slot. The result of taking the remainder of the downlink time slot divided by the uplink time slot can be used as the value of the bundling size.

[0065] The MAC CE can be configured as Figure 4 shown. The ACK field in the MAC CE can be used as the ACK bundling size indicator, and the value of the activated bundling size can be indicated through this field. The length of this ACK field can be 1 bit.

[0066] In some embodiments of the application, the indication information can include an indication parameter and an offset.

[0067] In the embodiments of the present application, the feedback timing of the HARQ acknowledgment messages corresponding to multiple downlink time slots can be jointly determined through the indication parameter and the offset. The indication parameter can indicate the uplink time slot corresponding to a feedback timing, and the offset can indicate the offset between the uplink time slots corresponding to the feedback timings of different downlink time slots.

[0068] Exemplarily, there are a total of 30 downlink time slots and 6 uplink time slots in the ATG pattern. Five offset k-offset values can be indicated through high-layer signaling to indicate the timing relationship of the HARQ acknowledgment messages of multiple downlink time slots. The definition of k-offset can be as follows:

[0069] Koffset SEQUENCE(SIZE(1..5))OF INTEGER(1..16)

[0070] It is understandable that the value of k-offset can be limited to 5, and the specific number of k-offset values is related to the ratio of uplink and downlink time slots in the TDD pattern.

[0071] Specifically, assume k1 = 30 and k-offset = 2, where μ is the SCS configuration for PUCCH transmission or PUSCH transmission; for FR1

[0072]

[0073] Among them, for the first time slot, only k1 = {30} is required to achieve the correct timing relationship; for the downlink time slots that feedback ACK / NACK information on the same uplink time slot, we assume that the value of k-offset is the same, so only 5 k-offset values are required to meet the timing relationship defined by the specification. Among them, k1 = {30, 25, 20, 15, 5}. Of course, the value of k1 is not limited to the above values and should change with the change of k-offset.

[0074] In some application embodiments, the indication information includes an indication parameter, an offset, and a relative offset.

[0075] Among them, the relative offset can be the relative offset with respect to the maximum offset value.

[0076] In the embodiments of the present application, the timing of the hybrid automatic repeat request acknowledgment message can be determined by an indication parameter, an offset, and a relative offset. Among them, the indication parameter and the offset can have the same meaning as in the above application embodiments. A time slot position can be determined for the downlink time slot based on the indication parameter and the offset, and an uplink time slot can be determined through the time slot position of the uplink time slot and the relative offset. This uplink time slot can be used to time and feedback the hybrid automatic repeat request acknowledgment message for a downlink time slot.

[0077] In some application embodiments, the relative offset is determined according to at least one of the following methods:

[0078] Configured according to radio resource control information and activated based on downlink control information;

[0079] Configured according to radio resource control information and activated based on a media access control layer control element;

[0080] Activated according to radio resource control information;

[0081] Activated according to downlink control information;

[0082] Activated according to the media access control layer control unit.

[0083] In an exemplary embodiment, the HARQ-ACK / HARQ-NACK in the ATG scenario can be jointly indicated by the k1 value, the k-offset value, and the k-relative offset. See Figure 5 , the maximum distance between the first downlink time slot and the first uplink time slot is 34. The time slot interval between the downlink PDSCH and the feedback HARQ-ACK can meet the existing specifications through k-offset. Specifically, it is as follows:

[0084] Assume k1 = 30 and k-offset = 2, then:

[0085]

[0086] where μ is the SCS configuration for PUCCH transmission or PUSCH transmission; for FR1

[0087] At this time, the UE is notified of the timing relationship k1 = 30 for the first time slot through the high-layer signaling DL-DataToUL-ACK-v1700, and for other downlink time slots, the relative offset can be indicated through high-layer parameters. The relative offset can be 5 bits in size, k-relative offset = {0, 1, 2, 3, 4, 4, 5, 6, 7, 8, 8, 9, 10, 11, 12, 12, 13, 14, 15, 16, 16, 17, 18, 19, 20, 20, 21, 22, 23, 24}. Specifically, the position of each uplink time slot can be determined in the following way:

[0088] ...

[0090]

[0091] In the embodiment of the present application, through the joint indication method of k1, k-offset, and k-relative offset, it can be ensured that only one k1 = {30} is required to achieve the timing enhancement of HARQ-ACK. It can be understood that the value of k-relative offset is not limited to the above values.

[0092] In the embodiments of the present application, there can be various signaling indication methods for the high-layer parameters of k-relative offset, including: RRC configuration, DCI activation; RRC configuration, MAC activation; RRC activation; DCI activation; MAC CE activation, etc. Taking the setting of the k-relative offset value by RRC configuration and DCI activation as an example:

[0093] Configure the k-relative offset value through RRC. The configuration method can be achieved through the following ways:

[0094] k-relative offset SEQUENCE(SIZE(1..32))OF INTEGER(0..31)

[0095] Taking the activation of the k-relative offset value by DCI as an example, there is no restriction on the DCI format. Format1-1 can be taken as an example:

[0096] PDSCH-to-HARQ ACK-feedback timing offset - 0, 1, 2, 3, 4, or 5 bits, as defined in the following table.

[0097] The bit width of this field is determined as where I is the number of entries in the higher-layer parameter k-relative offset.

[0098]

[0099] Based on some embodiments of the application, the primary cell and the secondary cell corresponding to the hybrid automatic repeat request acknowledgment message belong to different physical uplink control channel groups.

[0100] In the embodiments of the present application, the primary cell and the secondary cell of the uplink time slot corresponding to the hybrid automatic repeat request acknowledgement message may belong to different physical uplink control channel groups. Specifically, when the primary cell and the secondary cell belong to different PUCCH groups, they can be configured through different RRC signaling. In this case, the high-layer signaling PUCCH-Config will be different, the HARQ-ACK information corresponding to the primary cell and the secondary cell can be different, the indication information for the HARQ-ACK information corresponding to the primary cell and the secondary cell can be different, the indication information for the primary cell or the secondary cell may include downlink control information, the indication information includes 32 values, and the value range of each value is from 0 to 63; or, the above indication information may also include an indication parameter and a bundling granularity indication parameter, and the bundling granularity indication parameter indicates that at least two consecutive time slots share the timing of the hybrid automatic repeat request acknowledgement message indicated by the indication parameter; or, the above indication information may include an indication parameter, an offset, and a relative offset. The timing of the HARQ acknowledgement message feedback can be similar to that in the single-cell scenario, and the feedback timing of the corresponding HARQ acknowledgement message can be indicated respectively for the primary cell or the secondary cell through various indication information.

[0101] In some other embodiments of the application, the primary cell and the secondary cell corresponding to the hybrid automatic repeat request acknowledgement message belong to the same physical uplink control channel group.

[0102] In the embodiments of the present application, the primary cell and the secondary cell of the uplink time slot corresponding to the hybrid automatic repeat request message may belong to the same physical uplink control channel group.

[0103] Furthermore, based on the above embodiments of the application, it further includes:

[0104] For the secondary cell configured with a physical uplink control channel, the hybrid automatic repeat request acknowledgement message corresponding to the secondary cell is fed back in the resources of the secondary cell.

[0105] In the embodiments of the present application, the primary cell and the secondary cell of the uplink time slot corresponding to the hybrid automatic repeat request message may belong to the same physical uplink control channel group, and when the secondary cell of the physical uplink control channel is configured, the hybrid automatic repeat request acknowledgement message may be fed back in the resources of the secondary cell.

[0106] Furthermore, based on the above embodiments of the application, it further includes:

[0107] For the secondary cell without a configured physical uplink control channel, the hybrid automatic repeat request acknowledgement message corresponding to the secondary cell is fed back in the resources of the primary cell.

[0108] In the embodiments of the present application, the primary cell and the secondary cell of the uplink time slot corresponding to the hybrid automatic repeat request message may belong to the same physical uplink control channel group, and when the physical uplink control channel is not configured with a secondary cell, the hybrid automatic repeat request acknowledgement message may be fed back on the resources of the primary cell.

[0109] In an exemplary embodiment, when receiving on one carrier and feeding back on another carrier, taking Frequency Division Duplexing (FDD) 15KHZ + TDD30KHZ as an example, a solution for HARQ-ACK timing in the ATG multi-carrier scenario is introduced.

[0110] Through different RRC signaling configurations, when the primary cell and the secondary cell belong to different PUCCH groups, in this case, the high-layer signaling PUCCH-Config will be different, and the HARQ-ACK information of the primary cell and the secondary cell will also be different. At this time, the multi-carrier scenario can be the same as the single-cell scenario type, and the HARQ-ACK information for the primary cell and the secondary cell can be fed back separately. The feedback timing can be implemented in the manner introduced in the above application embodiments, including but not limited to that the timing indication information includes 32 values, and the value range of each value is from 0 to 63; or, the above indication information may also include an indication parameter and a bundling granularity indication parameter, and the bundling granularity indication parameter indicates that at least two consecutive time slots share the timing of the hybrid automatic repeat request acknowledgement message indicated by the indication parameter; or, the above indication information may include an indication parameter, an offset, and a relative offset, etc.

[0111] In some other application embodiments, when the primary cell and the secondary cell belong to the same PUCCH group, the high-layer signaling PUCCH-Config is configured for a primary cell group (MCG), and the DL-DataToUL-ACK of the primary cell and the secondary cell can be implemented through any of the above embodiments. And there are two ways for the feedback of HARQ-ACK / NACK: The first way is that when the secondary cell is configured in the high layer, the HARQ-ACK / NACK corresponding to the secondary cell can be fed back on the secondary cell. Another way is that when the secondary cell is not configured, the HARQ-ACK / NACK of the secondary cell can also be fed back on the primary cell.

[0112] Specifically, when a secondary cell is configured at a higher layer, the ACK information of the secondary cell can be fed back on the secondary cell. When feeding back the ACK information on the secondary cell, the timing indication method can be implemented by at least one of the following methods: the timing indication information includes 32 values, and the value range of each value is from 0 to 63; or, the above indication information can also include an indication parameter and a bundling granularity indication parameter, and the bundling granularity indication parameter indicates that at least two consecutive time slots share the timing of the hybrid automatic repeat request acknowledgment message indicated by the indication parameter; or, the above indication information can include an indication parameter, an offset, and a relative offset, etc.

[0113] When a secondary cell is not configured at a higher layer, the ACK information of the secondary cell can be fed back on the primary cell. Taking the primary cell TDD 30kHz and FDD 15kHz as the secondary cell as an example, the feedback timing of the HARQ acknowledgment message of the primary cell can be indicated by an indication parameter and a bundling granularity indication parameter. The bundling granularity indication parameter, that is, the size of Bundling, is 5, that is, each time slot bundling should contain 5 D time slots. At this time, k1 = {30, 25, 20, 15, 10, 5}. For the Scell, the bundling method can also be adopted, and the specific bundling granularity is configured by DCI signaling. As shown in the following figure, Pcell k1 = {30, 25, 17, 10}. Next Figure 6 Among them, the last 5 time slots of the Scell need to be fed back in the next time slot U of the Pcell. In this case, k1 = {30, 25, 20, 17, 15, 10, 5} can meet the specification.

[0114] It can be understood that the bundling granularity equal to 5 is only an example and is not limited. The bundling granularity can also have other values, and the size of the feedback k1 value can also have other values, as long as it meets the specification definition. The embodiments of the present application do not exclude other bundling values and k1 values that meet the specification.

[0115] In other embodiments, see Figure 7 , for the secondary cell, assuming k1 = 30 and k-offset = 2, at this time, for the first time slot of the secondary cell, it is compliant to indicate k1 = 30 through the higher layer signaling DL-DataToUL-ACK; for other downlink time slots, through the definition of the relative offset k-relative offset of the 5-bit size of the higher layer parameter = {1, 3, 5, 6, 8, 10, 11, 13, 15, 16, 18, 20,, 21, 23, 25, 26, 28, 30, -3, -1};

[0116] The uplink time slot position of other feedback HARQ acknowledgment messages can be determined by the following method:

[0117] ...

[0119]

[0120] In the embodiments of the present application, the last two uplink time slots of the secondary cell can be fed back in the next time slot of the primary cell. Therefore, its relative offset k-relative offset = {-3, -1}. The embodiments of the present application can determine the timing enhancement of HARQ ACK through a k1 = {30}.

[0121] In some other embodiments of the application, referring to Figure 8 , if k1 = 30 and k-offset = 2, it will cause the k-relative offset to be negative. To solve this problem, assume k1 = 31 and k-offset = 3; at this time, the k-relative offset of Pcell = {3, 4, 5, 6, 7, 7, 8, 9, 10, 11, 11, 12, 13, 14, 15, 15, 16, 17, 18, 19, 19, 20, 21, 22, 23, 23, 24, 25, 26, 27},

[0122] ...

[0124]

[0125] For the secondary cell Scell, k-relative offset = {4, 6, 8, 9, 11, 13, 14, 16, 18, 19, 21, 23, 24, 26, 28, 29, 31, 33, 0, 2}

[0126] ...

[0128]

[0129] It can be ensured that only one k1 = {31} is required to achieve the timing enhancement of HARQ ACK.

[0130] Different values of k1 and k-offset will result in different values of k-relative offset, but this does not affect the time slot of HARQ ACK.

[0131] In addition, the signaling indication method of the high-layer parameter of k-relative offset for Pcell and Scell can be indicated by different DCI signaling.

[0132] In addition, the k-relative offset value mentioned in the embodiments of the present application is only a reference, and different k1 and k-offset values will result in different outcomes, which have been described above. Therefore, the present invention does not exclude other k-relative offset values either.

[0133] On the other hand, for different configurations, such as TDD 30kHz Pcell + FDD 15kHz Scell, TDD 30kHz Pcell + TDD 30kHz Scell, TDD 15kHz Pcell + TDD 30kHz Scell, FDD 15kHz Pcell + TDD 30kHz Scell, FDD 15kHz Pcell + FDD 15kHz Scell, TDD 30kHz Pcell + TDD 30kHz Scell, etc., the method provided in the embodiments of the present application is also applicable.
