Description

Timing feedback methods, electronic devices and storage media Technical Field

[0001] This application relates to the field of wireless communication technology, such as timing feedback methods, electronic devices, and storage media. Background Technology

[0002] The introduction of Air-to-Ground (ATG) technology in wireless communication allows ground-based base stations to establish radio links with customer premises equipment (CPE) on aircraft, thereby achieving communication network coverage. Considering the unique deployment characteristics of ATG networks, with a maximum coverage range of 300 kilometers, and taking into account the long coverage distances and downlink service requirements in ATG scenarios, a new Time Division Duplex (TDD) pattern is introduced. Therefore, it is necessary to determine the Hybrid Automatic Repeat Request (HARQ) feedback and related timing schemes. In the 3GPP protocol, the timing of feedback is mainly addressed by configuring the number of processes required for HARQ feedback through higher-layer signaling. Specifically, this includes: the time slot offset between the downlink control information (DCI) received by the terminal on the Physical Downlink Control Channel (PDCCH) and its scheduling resources; the time slot offset between the PDSCH and its corresponding HARQ-ACK information fed back to the Physical Uplink Control Channel (PUCCH) or Physical Downlink Shared Channel (PDSCH); and the time slot offset between the uplink scheduling DCI and its scheduled PUSCH. However, in the ATG scenario, since the TDD cycle has 30 downlink time slots, the range of process numbers cannot cover long-latency, wide-coverage scenarios like ATG, resulting in incorrect timing feedback. Summary of the Invention

[0003] The embodiments of this application aim to provide a timing feedback method, electronic device, and storage medium to solve the timing feedback of HARQ acknowledgment information in long-latency, wide-coverage scenarios, enhance the timing relationship of HARQ acknowledgment information, and improve the communication performance of ATG scenarios.

[0004] This application provides a timing feedback method, wherein the method includes:

[0005] Obtain timing indication information for the hybrid automatic repeat request confirmation message; and feed back the hybrid automatic repeat request confirmation message according to the timing.

[0019] In the following description, the use of suffixes such as “module,” “part,” or “unit” to denote elements is solely for the purpose of illustration in this application and has no particular meaning in itself. Therefore, “module,” “part,” or “unit” may be used interchangeably.

[0020] With the advancement of wireless communication technology, new TDD patterns are introduced in long-latency, wide-coverage scenarios, such as ATG scenarios. How to perform HARQ feedback and determine the related timing for these new TDD patterns has become a pressing issue. Since long-latency, wide-coverage scenarios share certain similarities with non-terrestrial networks (NTN), some definitions from NTN can be reused. That is, the HARQ feedback process in long-latency, wide-coverage scenarios can adopt a similar process to that in NTN. The feedback timing in the HARQ feedback process in NTN scenarios can be determined by the k1 value. The k1 value indicates the time slot interval between the PDSCH and its HARQ-ACK feedback, and it has a total of 8 values, ranging from 0 to 31, as shown below:

[0021] DL-DataToUL-ACK-v1700::=SEQUENCE(SIZE(1..8))OF INTEGER(0..31)

[0022] The value k1 is defined as the slot offset between the PDSCH and its corresponding PUCCH or PUSCH, which is fed back with HARQ-ACK information. Due to the timing issue of HARQ-ACK, if the PDSCH reception ends in slot n, the UE can feed back the corresponding HARQ-ACK information within slot n+k1. Here, k1 is the number of slots, indicated by the PDSCH-to-HARQ-timing-indicator field in the DCI or provided by the higher-layer parameter dl-DataToUL-ACK, as shown in Figure 1. k1 = {34, 33, ..., 11, 10}, which exceeds the definition and range of the k1 value. Because the range of k1 values ​​cannot meet the requirements of long-latency, wide-coverage scenarios, it cannot be applied to solve the timing problem of HARQ feedback in ATG scenarios. Therefore, this application provides a timing feedback method to determine the timing of HARQ feedback in long-latency, wide-coverage scenarios, ensuring the timing of HARQ acknowledgment messages.

[0023] Figure 2 is a flowchart of a timing feedback method according to an embodiment of this application. This embodiment is applicable to HARQ timing feedback in ATG scenarios. The method can be executed by a timing feedback device, which can be implemented by software and / or hardware methods and is generally integrated into a terminal device. As shown in Figure 2, the method provided in this embodiment specifically includes 110 and 120.

[0024] 110. Obtain the timing indication information for the Hybrid Automatic Repeat Request Acknowledgment Message.

[0025] The Hybrid Automatic Repeat Request Acknowledgment Message can be an acknowledgment message from the UE regarding the reception status report of the PUCCH. The timing can be a specified time slot for feeding back the Hybrid Automatic Repeat Request Acknowledgment Message. The indication information can be information indicating the timing, which may include higher-layer parameters or downlink control information.

[0026] In this embodiment of the application, indication information can be obtained, which can indicate the timing of the hybrid automatic repeat request acknowledgment message. The indication information can indicate the time slot corresponding to the timing by indicating the number of timing time slots or the relative offset of the timing time slots, thereby expanding the coverage of the value of the timing indication.

[0027] 120. Based on the timed feedback of the automatic retransmission request confirmation message.

[0028] In this embodiment of the application, the time slot corresponding to the timing indicated by the indication information can be used to provide feedback on the hybrid automatic repeat request confirmation message through timing.

[0029] In this embodiment, by obtaining timing indication information for the Hybrid Automatic Repeat Request Acknowledgment (HARQ) message and feeding back the HARQ message according to the indicated timing, the timing feedback of HARQ acknowledgment information in long-latency, wide-coverage scenarios is resolved, the timing relationship of HARQ acknowledgment information is enhanced, and the communication performance in long-latency, wide-coverage scenarios is improved.

[0030] Based on the above application embodiments, the indication information includes downlink control information, and the indication information includes 32 values, each of which ranges from 0 to 63.

[0031] In this embodiment of the application, the indication information may specifically include downlink control information, which may include dl-DataToUL-ACK or the PDSCH-to-HARQ-timing-indicator field in DCI. The indication information may have 32 values, each of which may range from 0 to 63. The value of the indication information may not be 32, and the range of the values ​​may at least cover 30 downlink slots of the TDD cycle in the ATG scenario.

[0032] In an exemplary implementation, taking the DL-DataToUL-ACK field, which indicates that the DCI is included, as an example, this field can specifically be a sequence of size 32, where the value range for each position in the sequence can be 64, specifically 0-63. The DL-DataToUL-ACK field can be as follows: DL-DataToUL-ACK::=SEQUENCE(SIZE(1..32))OF INTEGER

[0033] In some embodiments of the application, the indication information includes indication parameters and bundled granularity indication parameters, wherein the bundled granularity indication parameters indicate the timing of a hybrid automatic repeat request acknowledgment message that is indicated by an indication parameter shared by at least two consecutive time slots.

[0034] The indication parameter can be a range parameter that indicates the feedback timing of the Hybrid Automatic Repeat Request Acknowledgment Message, while the bundled granularity indication parameter can indicate the number of time slots on which the indication parameter applies. The bundled granularity indication parameter can indicate multiple time slots as a whole, and this whole can share the timing of the Hybrid Automatic Repeat Request Acknowledgment Message indicated by a single indication parameter. The bundled granularity indication parameter can indicate the time slot on which the indication parameter applies.

[0035] In this embodiment, the indication information may include indication parameters and bundling granularity indication parameters. The bundling granularity indication parameter can indicate the time slot to which the indication parameter applies. For example, if the value of the bundling granularity indication parameter is 2, then the indication parameter in the indication information can indicate two consecutive time slots. These two time slots can determine the timing of the feedback hybrid automatic repeat request acknowledgment message through the indication parameter. In some embodiments, the bundling granularity indication parameter can indicate multiple discontinuous time slots as a whole. The allocation method of discontinuous time slots can be indicated by a Bitmap to determine which time slots belong to the same bundling granularity indication parameter. The length of the Bitmap can be the total number of downlink time slots D indicated by the bundling granularity indication parameter, with each bit corresponding to one time slot, and so on. 0 or 1 bit can be used to distinguish whether adjacent time slots belong to the same bundling granularity indication parameter. The granularity of whether discontinuous 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 bundle granularity indicator parameter can be a parameter sequence in which continuous or discontinuous time slots are indicated together to form a whole. This whole can share the timing feedback hybrid automatic repeat request acknowledgment message indicated by the indicator parameter.

[0036] In the above application embodiments, the timed feedback of the hybrid automatic retransmission request confirmation message includes:

[0037] The logical AND operation result of the mixed automatic repeat request acknowledgment message for at least two consecutive time slots indicated by the bundling granularity indicator parameter is determined, and the logical AND operation result is fed back according to the downlink time slot corresponding to the timing.

[0038] In the embodiments of this application, the bundling granularity indicator parameter can indicate multiple consecutive time slots, determine the mixed automatic repeat request messages of these consecutive time slots, and perform a logical AND operation on these mixed automatic repeat request messages. The operation result can be fed back through the uplink time slot corresponding to the indicator parameter, thereby realizing that multiple consecutive time slots share the timing indicated by the same indicator parameter.

[0039] In other embodiments, the automatic retransmission confirmation message is based on timed feedback, including:

[0040] Determine the acknowledgment feedback sequence corresponding to the hybrid automatic repeat request acknowledgment message for at least two consecutive time slots indicated by the bundling granularity indicator parameter, and feed back the acknowledgment feedback sequence according to the downlink time slot corresponding to the timing.

[0041] The acknowledgment feedback sequence can be a sequence of multiple hybrid automatic repeat request acknowledgment messages. The acknowledgment feedback sequence can include multiple elements, and the value of each element can correspond to a hybrid automatic repeat request acknowledgment message. The acknowledgment feedback sequence can correspond to the hybrid automatic repeat request acknowledgment messages of multiple consecutive time slots indicated by the bundling granularity indicator parameter. The position of each element in the acknowledgment feedback sequence can be the same as the position of the corresponding time slot in the multiple consecutive time slots indicated by the bundling granularity indicator parameter.

[0042] In this embodiment of the application, multiple time slots belonging to a bundle granularity indicator parameter can be determined, and the hybrid automatic repeat request confirmation messages of the multiple time slots corresponding to the bundle granularity indicator parameter can be obtained. Each hybrid automatic repeat request confirmation message can be formed into an confirmation feedback sequence, and the confirmation feedback sequence can be fed back through the timing corresponding to the indicator parameter.

[0043] Based on the above-described embodiments, the value of the binding granularity indicator parameter is determined by at least one of the following:

[0044] 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 media access control layer control unit.

[0045] In this embodiment, the value of the bundling granularity indication parameter can be indicated by downlink control information; or, one or more values ​​can be configured by Radio Resource Control (RRC) information, and the configured values ​​can be activated by downlink control information. When the bundling granularity indication parameter is activated by downlink control information, multiple time slots can share one indication parameter according to the bundling granularity indication parameter; or, the value of the bundling granularity indication parameter can be configured by radio resource control information, and the configured value of the bundling granularity indication parameter can be activated by the Media Access Control Element (MAC CE). When the bundling granularity indication parameter is activated, multiple time slots can share one indication parameter according to the bundling granularity indication parameter.

[0046] In an exemplary implementation, the timing of the mixed automatic repeat request acknowledgment messages can be indicated by k1 and k1 bundling. Referring to Figure 3, multiple consecutive time slots can be treated as a whole, i.e., a bundle. Time slots within the same bundle follow a k1 value. The specific bundle is indicated by higher-layer signaling and / or DCI, and a reasonable k1 value can be defined by higher-layer parameters for each bundle. Regarding the size of the bundle value, it is advisable to consider feeding back HARQ-ACK information on each U time slot as much as possible, without limiting the size of the bundle value. In the ATG scenario shown in Figure 3, with 30 D time slots and 6 U time slots, the bundle value is 5, meaning each time slot bundle should contain 5 D time slots. In Figure 3, every 5 downlink time slots can be considered as a bundle, using a k1 value for feedback on the U time slot. For example, k1 = {30, 25, 20, 15, 10, 5}. The timing issue of HARQ-ACK can be resolved using the k1 value.

[0047] Based on the above application embodiments, referring to Figure 3, HARQ-ACK or HARQ-NACK in the downlink time slot within the same bundle can perform a logical AND operation, and only the result of the logical AND operation can be fed back in the uplink time slot corresponding to the k1 value.

[0048] In other application embodiments, referring to Figure 3, the HARQ-ACK or HARQ-NACK of the downlink time slot within the same bundle is fed back in the corresponding uplink time slot, as shown above. At this time, the UE should feed back a 0, 1 sequence in the corresponding uplink time slot to correspond to the HARQ-ACK or HARQ-NACK information of each downlink time slot.

[0049] Based on the above application embodiments, the timing of HARQ confirmation message feedback in the ATG scenario can be determined by k1 bundling and k1. The value of bundling can be indicated by DCI or MAC CE.

[0050] In some application embodiments, the value of bundling can be configured via RRC and activated via DCI.

[0051] For example, RRC can configure the bundle value as follows:

[0052] In this embodiment of the application, the value of the bundling size can be allocated through downlink time slots and uplink time slots, and the result of dividing the downlink time slot by the uplink time slot and taking the remainder can be used as the value of the bundling size.

[0053] DCI activation: It can be activated via the ACK bundling size indicator. When the higher-level instruction ack-BundlingType is set to "Bundling", the bundling size value can be activated by indicating the value of ACK bundling size indicator.

[0054] In other application embodiments, the value of bundle can be configured via RRC and activated by MAC CE; for example, the value of bundle can be configured via RRC as follows:

[0055] In this embodiment of the application, the value of the bundling size can be allocated through downlink time slots and uplink time slots, and the result of dividing the downlink time slot by the uplink time slot and taking the remainder can be used as the value of the bundling size.

[0056] The MAC CE can be configured as shown in Figure 4. The ACK field in the MAC CE can be used as an ACK bundling size indicator. This field can indicate the value of the active bundling size. The length of the ACK field can be 1 bit.

[0057] In some embodiments, the indication information may include indication parameters and offset.

[0058] In this embodiment, the feedback timing of HARQ acknowledgment messages corresponding to multiple downlink time slots can be determined by 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 different downlink time slots.

[0059] For example, the ATG pattern has a total of 30 downlink slots and 6 uplink slots. The timing relationship of HARQ acknowledgment messages in multiple downlink slots can be indicated by 5 offset k-offset values ​​through higher-layer signaling. The k-offset can be defined as follows: Koffset SEQUENCE(SIZE(1..5)) OF INTEGER(1..16)

[0060] 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.

[0061] Assume k1 = 30, k-offset = 2, where μ is the SCS configuration for PUCCH or PUSCH transmission; for

[0062] For the first time slot, only k1 = {30} is needed to achieve the correct timing relationship. For downlink time slots that feed back ACK / NACK information on the same uplink time slot, we assume that the k-offset values ​​are the same, so only 5 k-offset values ​​are needed to satisfy the timing relationship defined in the specification. Here, k1 = {30, 25, 20, 15, 5}. The k1 value is not limited to the above values ​​but should vary with the k-offset.

[0063] In some embodiments of the application, the indication information includes indication parameters, offset, and relative offset.

[0064] The relative offset can be a relative offset to the maximum offset value.

[0065] In this embodiment, the timing of the hybrid automatic repeat request acknowledgment message can be determined by an indication parameter, an offset, and a relative offset. The indication parameter and the offset can have the same meaning as in the embodiments described above. The downlink time slot determines a time slot position based on the indication parameter and the offset. An uplink time slot can be determined by the time slot position of the uplink time slot and the relative offset. The uplink time slot can be used to provide timing feedback for the hybrid automatic repeat request acknowledgment message of a downlink time slot.

[0066] In some embodiments, the relative offset is determined according to at least one of the following methods:

[0067] 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 media access control layer control unit; activated according to radio resource control information; activated according to downlink control information; activated according to media access control layer control unit.

[0068] In an exemplary implementation, the k1 value, k-offset value, and k-relative offset can be used to jointly indicate HARQ-ACK / HARQ-NACK in an ATG scenario. Referring to Figure 5, the maximum distance between the first downlink time slot and the first uplink time slot is 34. The k-offset can be used to ensure that the time slot interval between the downlink PDSCH and the feedback HARQ-ACK meets the specification, as shown below:

[0069] Assuming k1 = 30 and k - offset = 2, then we have:

[0070] Where μ is the SCS configuration for PUCCH or PUSCH transmission; for

[0071] At this point, for the first time slot, the timing relationship k1 = 30 is notified to the UE via higher-layer signaling DL-DataToUL-ACK-v1700. For other downlink time slots, the relative offset can be indicated by higher-layer parameters. This 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 as follows:

[0072] In this embodiment of the application, k1 and k-offset (the parameter K in the formula) are used. offset ) and k-relative offset (the parameter K in the formula) relative offset The common indication method can ensure that only one k1 = {30} is needed to achieve timing enhancement of HARQ-ACK, and the value of k-relative offset is not limited to the above value.

[0073] In this embodiment, the signaling indication method for the higher-layer parameter of the k-relative offset can be various, including: RRC configuration, DCI activation; RRC configuration, MAC activation; RRC activation; DCI activation; MAC CE activation, etc. Taking setting the k-relative offset value through RRC configuration and DCI activation as an example:

[0074] The k-relative offset value can be configured via RRC as follows: `k-relative offset SEQUENCE(SIZE(1..32))OF INTEGER(0..31)`

[0075] Taking the activation of the k-relative offset via DCI as an example, the DCI format is not restricted; Format 1-1 can be used as an example:

[0076] PDSCH-to-HARQ ACK-feedback timing offset - 0, 1, 2, 3, 4, or 5 bits, defined in the table below. The bit width of this field is determined as follows: Where I is the number of entries in the higher-level parameter k-relative offset.

[0077] Based on some application embodiments, the primary and secondary cells corresponding to the hybrid automatic repeat request confirmation messages belong to different physical uplink control channel groups.

[0078] In this embodiment, the primary and secondary cells of the uplink time slot corresponding to the hybrid automatic repeat request acknowledgment message can belong to different physical uplink control channel groups. Specifically, when the primary and secondary cells belong to different PUCCH groups, they can be configured with different RRC signaling. In this case, the higher-layer signaling PUCCH-Config will be different, and the HARQ-ACK information corresponding to the primary and secondary cells can be different. The indication information for the HARQ-ACK information of the primary cell and the HARQ-ACK information of the secondary cell can be different. The indication information for the primary or secondary cell can include downlink control information, and the indication information includes 32 values, each ranging from 0 to 63; or, the indication information can also include indication parameters and bundling granularity indication parameters, where the bundling granularity indication parameters indicate the timing of the hybrid automatic repeat request acknowledgment message indicated by the indication parameters shared by at least two consecutive time slots; or, the indication information can include indication parameters, offset, and relative offset. The timing of the HARQ acknowledgment message feedback can be similar to that in a single-cell scenario, and the feedback timing of the corresponding HARQ acknowledgment message can be indicated by various indication information for the primary or secondary cell.

[0079] In other application embodiments, the primary cell and secondary cell corresponding to the hybrid automatic repeat request acknowledgment message belong to the same physical uplink control channel group.

[0080] In this embodiment of the application, the primary cell and the secondary cell corresponding to the uplink time slot of the hybrid automatic repeat request message can belong to the same physical uplink control channel group.

[0081] Based on the above-described embodiments, it also includes:

[0082] For secondary cells configured with physical uplink control channels, the corresponding hybrid automatic repeat request acknowledgment messages for the secondary cells are fed back to the resources of the secondary cells.

[0083] In this embodiment of the application, the primary cell and secondary cell of the uplink time slot corresponding to the hybrid automatic repeat request message can 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 acknowledgment message can be fed back on the resources of the secondary cell.

[0084] Based on the above-described embodiments, it also includes:

[0085] For secondary cells that are not configured with a physical uplink control channel, the corresponding hybrid automatic repeat request confirmation message of the secondary cell is fed back to the resource in the primary cell.

[0086] In this embodiment of the application, the primary cell and secondary cell of the uplink time slot corresponding to the hybrid automatic repeat request message can 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 confirmation message can be fed back in the resources of the primary cell.

[0087] In one exemplary implementation, a solution for HARQ-ACK timing in an ATG multi-carrier scenario is introduced, taking Frequency Division Duplexing (FDD) 15kHz + TDD 30kHz as an example, where reception is performed on one carrier and feedback is performed on another carrier.

[0088] With different RRC signaling configurations, when the primary and secondary cells belong to different PUCCH groups, the higher-layer signaling PUCCH-Config will be different, and the HARQ-ACK information of the primary and secondary cells will also be different. In this case, the multi-carrier scenario can be treated the same as the single-cell scenario, and the HARQ-ACK information of the primary and secondary cells can be fed back separately. The timing of the feedback can be implemented in the manner described in the above application embodiments, wherein the timing indication information includes 32 values, each ranging from 0 to 63; or, the above indication information may also include indication parameters and bundling granularity indication parameters, wherein the bundling granularity indication parameters indicate the timing of the hybrid automatic repeat request acknowledgment message indicated by the indication parameters shared by at least two consecutive time slots; or, the above indication information may include indication parameters, offsets, and relative offsets, etc.

[0089] In other application embodiments, when the primary cell and secondary cell belong to the same PUCCH group, the higher-layer signaling PUCCH-Config is configured for a primary cell group (MCG), and the DL-DataToUL-ACK of the primary cell and secondary cell can be implemented through any of the above embodiments. The HARQ-ACK / NACK feedback can occur in two ways: the first way is when a secondary cell is configured at the higher layer, in which case the HARQ-ACK / NACK of the corresponding secondary cell can be fed back on the secondary cell. The other way is when no secondary cell is configured, in which case the HARQ-ACK / NACK of the secondary cell can also be fed back on the primary cell.

[0090] When a secondary cell is configured at the higher level, the ACK information of the secondary cell can be fed back on the secondary cell. When the ACK information is fed back on the secondary cell, the timing indication method can be implemented in at least one of the following ways: the timing indication information includes 32 values, each value ranging from 0 to 63; or, the above indication information can also include indication parameters and bundling granularity indication parameters, the bundling granularity indication parameters indicating the timing of the hybrid automatic repeat request acknowledgment message indicated by the indication parameters shared by at least two consecutive time slots; or, the above indication information can include indication parameters, offset, and relative offset, etc.

[0091] When no secondary cell is configured at the upper layer, the ACK information of the secondary cell can be fed back on the primary cell. Taking the primary cell with TDD 30kHz and FDD 15kHz as the secondary cell as an example, the timing of the HARQ acknowledgment message feedback from the primary cell can be indicated by the indication parameter and the bundling granularity indication parameter. The bundling granularity indication parameter, i.e., the size of the bundling, is 5, meaning that each time slot bundling should contain 5 D time slots, in which case k1 = {30, 25, 20, 15, 10, 5}. For S cells, the bundling method can also be used. The specific bundling granularity is configured by the DCI signaling, as shown in the figure below. For P cell, k1 = {30, 25, 17, 10}. In Figure 6, the last 5 time slots of the S cell need to be fed back in the next time slot U of the P cell. In this case, k1 = {30, 25, 20, 17, 15, 10, 5} can meet the specification.

[0092] A bundling granularity of 5 is merely an example and not a limitation. Other values ​​are possible for the bundling granularity, as is the value of the feedback k1, as long as they conform to the specification definition. This application's embodiments do not exclude other bundleling and k1 values ​​that conform to the specification.

[0093] In other embodiments, referring to Figure 7, for a secondary cell, assuming k1 = 30 and k-offset = 2, the first time slot of the secondary cell indicates that k1 = 30 meets the specification via higher-layer signaling DL-DataToUL-ACK; while for other downlink time slots, the relative offset of the higher-layer parameter k-relative offset = {1,3,5,6,8,10,11,13,15,16,18,20,,21,23,25,26,28,30,-3,-1} is defined; the uplink time slot positions of other feedback HARQ acknowledgment messages can be determined in the following way:

[0094] In this embodiment, 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}. This embodiment can determine the timing enhancement of HARQACK using a k1 = {30}.

[0095] In some other embodiments, referring to Figure 8, if k1 = 30 and k-offset = 2, the k-relative offset will be negative. To solve this problem, assume k1 = 31 and k-offset = 3; then the k-relative offset of Pcell is {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}.

[0096] For the secondary cell Scell, the k-relative offset is {4,6,8,9,11,13,14,16,18,19,21,23,24,26,28,29,31,33,0,2}.

[0097] It can be guaranteed that only one k1 = {31} is needed to achieve timing enhancement of HARQ ACK.

[0098] Different k1 and k-offset values ​​will result in different values ​​for the k-relative offset, but this does not affect the HARQ ACK slot.
