[0031] The feedback information sending method provided by the embodiments of the present application will be described in detail below in combination with the drawings, specific embodiments and application scenarios.

[0032] Figure 2 A flowchart of a feedback information sending method provided by the embodiments of the present application is shown. The method can be executed by a terminal, in other words, the method can be executed by software or hardware installed in the terminal. As shown in Figure 2 the method can include the following steps.

[0033] In step S201, according to the feedback mode and the received target parameter value, a feedback position corresponding to a physical downlink shared channel scheduled by downlink control information is determined according to a first rule.

[0034] The target parameter value can be selected from a k1 set configured by a higher layer, and when the number of k1 candidate values contained in the k1 set is greater than 1, a specific k1 value used as the target parameter value can be indicated in downlink control information. The target parameter value can also be carried by the downlink control information.

[0035] There are various feedback mode setting methods. In an embodiment, a default feedback mode can be set for a terminal in advance, and the default feedback mode can be indicated by a higher layer or a protocol. In another embodiment, the feedback mode is determined by first indication information.

[0036] The first indication information is obtained by at least one of the following methods:

[0037] According to a protocol definition;

[0038] According to a base station indication;

[0039] According to a higher layer indication;

[0040] Indicated by an indication field carried in downlink control information.

[0041] The terminal can select one of the pre-set feedback modes according to the received first indication information, and determine the feedback position corresponding to each PDSCH scheduled according to the first rule in combination with the received target parameter value, so as to send the feedback information, such as HARQ-ACK, corresponding to the PDSCH at the feedback position.

[0042] It should be understood that the feedback position is located in a channel for uplink transmission, which can be a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH).

[0043] Thus, the feedback information sending method provided by the embodiments of the present application can enable the terminal to determine the feedback position of each physical downlink shared channel according to the feedback mode and the received target parameter value according to the first rule in the case of one downlink control information scheduling multiple PDSCHs, so as to ensure accurate transmission of feedback information and improve data transmission efficiency.

[0044] Figure 3 Another flowchart of the feedback information sending method provided by the embodiments of the present application is shown, which can be executed by a terminal, in other words, the method can be executed by software or hardware installed in the terminal. As shown in FIG. 6, the method comprises the following steps: Figure 3As shown, the method may include the following steps:

[0045] Step S301: When the feedback method is that the received physical downlink shared channels provide feedback at the same time, based on the received first target parameter value and taking the first time slot where the first physical downlink shared channel is located as a reference, determine the feedback positions corresponding to all physical downlink shared channels; wherein, the first target parameter value indicates the interval between the feedback position and the first time slot.

[0046] There are multiple ways to set the feedback method.

[0047] In one implementation, a default feedback method can be pre-set for the terminal, which can be indicated by higher-level instructions or protocol instructions.

[0048] In another implementation, the feedback method is determined by the first indication information;

[0049] The first indication information is obtained through at least one of the following methods:

[0050] According to the predefined protocol;

[0051] According to the base station instructions;

[0052] As instructed by higher authorities;

[0053] Indicated by the indication field carried in the downlink control information.

[0054] The first physical downlink shared information can be any designated PDSCH that is scheduled. In one embodiment, the first physical downlink shared channel is the last PDSCH or the first PDSCH among the scheduled PDSCHs.

[0055] It should be understood that the first target parameter value is a numerical value, namely a K1 value.

[0056] like Figure 4 As shown, DCI D1 schedules multiple PDSCHs P1-P5. Based on the value of k1, the feedback position B1 corresponding to each PDSCH can be determined. The interval between the feedback position B1 and the last PDSCH P5 is indicated by k1. For example, if the time slot where the last PDSCH P5 is located is n, then the time slot where the feedback position is located is n+k1. In other words, only one k1 value is needed to determine the feedback position of each scheduled PDSCH.

[0057] Thus, the feedback information sending method provided by the embodiments of the present application can determine the feedback positions corresponding to all physical downlink shared channels based on the received first target parameter value and the first time slot in which the first physical downlink shared channel is located, in the case that the feedback mode is that the received physical downlink shared channels are fed back at the same time, so that in the case that one downlink control information schedules multiple PDSCHs, the terminal can confirm the feedback positions of each physical downlink shared channel through smaller DCI overhead, guarantee the accurate transmission of feedback information, and improve the transmission efficiency of data.

[0058] Figure 5 Another flowchart of the feedback information sending method provided by the embodiments of the present application is shown, which can be executed by a terminal, in other words, the method can be executed by software or hardware installed in the terminal. As shown in the figure, the method can include the following steps: Figure 5

[0059] In the case that the feedback mode is that the received physical downlink shared channels are fed back at different times, the received physical downlink shared channels are grouped.

[0060] There are multiple feedback mode setting methods. In one embodiment, a default feedback mode can be preset for the terminal, which can be indicated by a high layer or a protocol. In another embodiment, the feedback mode is determined by first indication information;

[0061] The first indication information is obtained by at least one of the following methods:

[0062] According to a protocol;

[0063] According to a base station indication;

[0064] According to a high layer indication;

[0065] Indicated by an indication field carried in the downlink control information.

[0066] Further, the grouping of the received physical downlink shared channels includes:

[0067] The received physical downlink shared channels are grouped according to at least one grouping parameter;

[0068] The grouping parameter includes:

[0069] The first number of physical downlink shared channels included in each group;

[0070] The second number of time slots occupied by the physical downlink shared channels included in each group.

[0071] ​Since the calling manner of the called PDSCH can be set according to actual needs, including: using the manner that each PDSCH occupies one slot, and also using the manner that multiple PDSCHs are called in one slot. Therefore, when grouping, corresponding grouping parameters can be set according to the transmission manner of the PDSCH. For example, for the manner that each PDSCH occupies one slot, only the first quantity or the second quantity needs to be determined for grouping. For the manner that multiple PDSCHs are called in one slot, grouping needs to be performed according to the combination of the first quantity and the second quantity.

[0072] In an implementation manner, grouping can be performed based on the first quantity L, and the multiple PDSCHs scheduled are grouped into a group of every L PDSCHs until the last PDSCH scheduled.

[0073] In another implementation manner, grouping can be performed based on the second quantity N, and the multiple slots in which the multiple PDSCHs scheduled are located are grouped into a group of PDSCHs contained in every N slots until the slot in which the last PDSCH scheduled is located.

[0074] Further, the first quantity or the second quantity is determined by at least one of the following:

[0075] Protocol pre-configuration;

[0076] High-layer indication;

[0077] Subcarrier spacing (SCS) of a received physical downlink control channel;

[0078] Subcarrier spacing of a scheduled physical downlink shared channel; that is, according to the scaling relationship between different SCSs received or scheduled and the first quantity or the second quantity, for example, when the default SCS is 480K, 4 PDSCHs are grouped; when the SCS is 960K, 8 PDSCHs are grouped;

[0079] Bit length of feedback information. In the case of single DCI scheduling multiple PDSCHs, the bit length of the feedback information needs to be obtained.

[0080] Further, the bit length of the feedback information is determined by at least one of the following:

[0081] Protocol pre-configuration;

[0082] High-layer indication;

[0083] Subcarrier spacing of a received physical downlink control channel;

[0084] Subcarrier spacing of a scheduled physical downlink shared channel.

[0085] For example, a fixed bit length is fed back when multiple PDSCHs are scheduled by a protocol each time, including the default feedback information, which is HARQ-ACK with a bit length of 4 bits. According to 4 bits, the multiple PDSCHs are grouped. Taking grouping according to the first quantity as an example, assuming that there are 16 PDSCHs in total, then every 4 PDSCHs form a group; assuming that there are 8 PDSCHs in total, then every 2 PDSCHs form a group; assuming that there are 14 PDSCHs in total, then the first three groups each contain 4 PDSCHs, and the last group contains 2 PDSCHs, or the first group can contain 2 PDSCHs and the last three groups contain 4 PDSCHs. In the grouping process, the number of PDSCHs contained in each group can be set as needed to ensure that the bit length of the HARQ-ACK fed back each time is consistent. Taking grouping according to the second quantity as an example, assuming that 20 PDSCHs occupy 16 slots in total, then every 4 PDSCHs form a group to ensure that the number of bits of the HARQ-ACK fed back is consistent.

[0086] In step S502, the feedback positions corresponding to each group are determined according to the grouping result and the received target parameter value.

[0087] According to the grouping result, the feedback positions of each PDSCH group are determined in combination with the received target parameter value.

[0088] The received target parameter value can be selected from a k1 set configured by a higher layer, and when the k1 candidate values contained in the k1 set are greater than 1, a specific k1 value used as the target parameter value can be indicated in the received downlink control information. The target parameter value can also be carried by the downlink control information.

[0089] It should be understood that the feedback positions corresponding to each group can be different, the same, or partially the same. Taking three groups as an example, the first group, the second group, and the third group correspond to feedback positions B1, B2, and B3 respectively, B1, B2, and B3 can be three different time slots, or the same time slot, or 2 of them in the same time slot. For the sake of simplicity, in the following embodiments, B1, B2, and B3 are taken as three different time slots as examples.

[0090] Therefore, the feedback information sending method provided by the embodiments of the present application groups the received physical downlink shared channels in the case that the feedback manner is that the received physical downlink shared channels are fed back at different time instants; determines the feedback positions corresponding to each group according to the grouping result and the received target parameter value, so that in the case that one downlink control information schedules multiple PDSCHs, the terminal confirms the feedback position of each physical downlink shared channel, ensures the accurate transmission of the feedback information, and improves the transmission efficiency of data.

[0091] Figure 6 Another flowchart of the method for sending feedback information provided by the embodiments of the present application is shown, which can be executed by a terminal, in other words, the method can be executed by software or hardware installed in the terminal. As shown in the figure, the method can include the following steps: Figure 6

[0092] Step S601: In the case that the feedback mode is that the received physical downlink shared channel is fed back at different time instants, grouping the received physical downlink shared channel.

[0093] The step S601 performs the same method as the step S501, and the same or similar beneficial effects are obtained, and the same parts will not be described here.

[0094] Step S602: According to the target parameter value received in the downlink control information and the corresponding relationship between the target parameter value and each group, determining the feedback position corresponding to each group.

[0095] The target parameter value received by the terminal from the downlink control information has a corresponding relationship (combination) with each PDSCH group.

[0096] In an embodiment, the target parameter value received in the downlink control information includes a second target parameter value corresponding to each group respectively; wherein the second target parameter value is based on the time slot where the second physical downlink shared channel in the corresponding group is located.

[0097] The second physical downlink shared channel can be any designated PDSCH in the group, and in an embodiment, the second physical downlink shared channel is the last physical downlink shared channel or the first physical downlink shared channel in the group.

[0098] As Figure 7 ​As shown, the grouping results of PDSCH are P1 and P2 for the first PDSCH group, P3 and P4 for the second PDSCH group, and P5 for the third PDSCH group. The received target parameter values include: k1=10 corresponding to the first group, k1=11 corresponding to the second group, and k1=15 corresponding to the third group. Taking the time slot in which the last PDSCH P2 of the first group is located as the reference, and taking k1=10 as the interval, the time slot B1 in which the PUCCH or PUSCH as the feedback position corresponding to the first group is located is obtained. Taking the time slot in which the last PDSCH P4 of the second group is located as the reference, and taking k1=11 as the interval, the time slot B2 in which the PUCCH or PUSCH as the feedback position corresponding to the second group is located is obtained. Taking the time slot in which the last PDSCH P5 of the third group is located as the reference, and taking k1=15 as the interval, the time slot B3 in which the feedback position of the PUCCH or PUSCH corresponding to the third group is located is obtained.

[0099] In another embodiment, the target parameter value received in the downlink control information includes a third target parameter value corresponding to the first group; wherein the third target parameter value takes the time slot in which the second physical downlink shared channel of the first group is located as the reference.

[0100] One target parameter value, i.e., the third target parameter value corresponding to the first group, is provided in the DCI.

[0101] The first group is the first group or the last group among all groups, or can be any designated group.

[0102] The terminal determines the feedback positions corresponding to the groups according to the grouping order based on the third target parameter value.

[0103] In one embodiment, in the case where the third target parameter value indicates that the feedback position corresponding to the first group is in the first time slot, the time slots in which the feedback positions corresponding to the groups are located are determined by sequentially adding 1 or subtracting 1 from the first time slot as the reference according to the grouping order, and the time slots in which the feedback positions are located are time slots for uplink transmission.

[0104] In one embodiment, if the time slot after adding 1 or subtracting 1 is a time slot for downlink transmission, the time slot is skipped, and the adding 1 or subtracting 1 is continued until a time slot for uplink transmission is obtained.

[0105] As Figure 8As shown, P1 and P2 are the first PDSCH group, P3 and P4 are the second PDSCH group, and P5 is the third PDSCH group. The terminal receives the third target parameter k1 corresponding to the first group, and takes the time slot where the first PDSCH P1 in the first group is located as the reference, first obtains the feedback position B1 corresponding to the first group, and sequentially adds 1 to the feedback positions corresponding to other groups to obtain the feedback position B2 corresponding to the second group and the feedback position B3 corresponding to the third group.

[0106] As shown in the first group and the second group, after obtaining the feedback positions B1 and B2 corresponding to the first group and the second group, since the time slots after B2 are time slots for downlink transmission, when determining the feedback position corresponding to the third group by sequentially adding 1, two time slots for downlink transmission B3 and B4 need to be continuously skipped, and B5 is taken as the feedback position corresponding to the third group. Figure 9 As shown in the first group and the second group, after obtaining the feedback positions B1 and B2 corresponding to the first group and the second group, since the time slots after B2 are time slots for downlink transmission, when determining the feedback position corresponding to the third group by sequentially adding 1, two time slots for downlink transmission B3 and B4 need to be continuously skipped, and B5 is taken as the feedback position corresponding to the third group.

[0107] Figure 8 As shown, taking sequentially subtracting 1 as an example, the terminal receives the third target parameter k1 corresponding to the third group, and takes the time slot where the last PDSCH P5 in the third group is located as the reference, first obtains the feedback position B3 corresponding to the third group, and then sequentially subtracts 1 from the feedback positions corresponding to other groups to obtain the feedback position B2 corresponding to the second group and the feedback position B1 corresponding to the first group.

[0108] As shown, taking sequentially subtracting 1 as an example, after obtaining the feedback position B5 corresponding to the third group, since the time slots before B5 are time slots for downlink transmission, when determining the feedback position corresponding to the second group by sequentially subtracting 1, two time slots for downlink transmission B4 and B3 need to be continuously skipped, and B2 and B1 are taken as the feedback positions corresponding to the second group and the first group, respectively. Figure 9 Further, the received target parameter value is not necessarily a numerical type. The data type of the target parameter value is indicated by the second indication information;

[0109] The data type includes at least one of the following types: numerical type, non-numerical type.

[0110] The second indication information is determined by at least one of the following ways:

[0111] The target indication field of the downlink control information; wherein the target indication field is used to indicate the data type of the target parameter value; the target indication field can be an additional indication field added in the DCI;

[0112]

[0113] ​​a target value of another indication field in the downlink control information; wherein the target value is used to indicate a data type of the target parameter value; the target indication field can also be an existing indication field of the DCI, and a specific target value is used to indicate the data type of the target parameter value.

[0114] If there are multiple target parameter values received, the data type of each target parameter value or part of the target parameter values can be indicated by the second indication information. The second indication information can also be determined by a target indication field of the downlink control information or a target value of another indication field in the downlink control information.

[0115] The data type of part of the target parameter values can be a plurality of target parameter values connected, generally the first target parameter value, after which a plurality of target parameter values are connected.

[0116] Thus, the feedback information sending method provided by the embodiments of the present application groups the received physical downlink shared channels in the case that the feedback mode is that the received physical downlink shared channels are fed back at different time instants; determines the feedback positions corresponding to each group according to the target parameter values received in the downlink control information and the correspondence between the target parameter values and each group, and gives a plurality of determination methods of the correspondence and the feedback positions, so that in the case that one downlink control information schedules a plurality of PDSCHs, the terminal can flexibly select a method for determining the feedback positions of each PDSCH according to the need, so as to ensure the accurate transmission of the feedback information and improve the transmission efficiency of the data.

[0117] It should be noted that the feedback information sending method provided by the embodiments of the present application can be executed by a feedback information sending device, or a control module in the feedback information sending device for executing the method of sending feedback information. In the embodiments of the present application, the feedback information sending device is taken as an example to illustrate the feedback information sending device provided by the embodiments of the present application.

[0118] Figure 10 A structure schematic diagram of the feedback information sending device provided by the embodiments of the present application is shown in FIG. 1. Figure 10 As shown in FIG. 1, the device comprises an acquisition module 11 and an execution module 12.

[0119] The acquisition module 11 is used to acquire the feedback mode and the target parameter value; the execution module 12 is used to determine the feedback positions corresponding to the physical downlink shared channels scheduled by the downlink control information according to the feedback mode and the target parameter value according to a first rule.

[0120] Further, the feedback mode is determined by first indication information;

[0121] The first indication information is acquired by at least one of the following manners:

[0122] According to a protocol definition;

[0123] According to a base station indication;

[0124] According to a high-layer indication;

[0125] Indicated by an indication field carried in downlink control information.

[0126] Further, the feedback manner includes at least one of the following:

[0127] The received physical downlink shared channels are fed back at the same time;

[0128] The received physical downlink shared channels are fed back at different times.

[0129] Therefore, the feedback information sending method provided by the embodiments of the present application can determine the feedback positions corresponding to the physical downlink shared channels scheduled by the downlink control information according to the feedback manner and the received target parameter value according to the first rule, so that the terminal can confirm the feedback positions of each physical downlink shared channel in the case of one downlink control information scheduling multiple PDSCHs, and the accurate transmission of feedback information is ensured and the transmission efficiency of data is improved.

[0130] Based on the above embodiments, further, the execution module is configured to, in the case that the feedback manner is that the received physical downlink shared channels are fed back at the same time, determine the feedback positions corresponding to all the physical downlink shared channels according to the received first target parameter value, taking the first time slot in which the first physical downlink shared channel is located as a reference; wherein the first target parameter value indicates the interval between the feedback position and the first time slot.

[0131] Further, the first target parameter value is a numerical value.

[0132] Further, the first physical downlink shared channel is the last physical downlink shared channel in the scheduled physical downlink shared channels.

[0133] Therefore, the feedback information sending method provided by the embodiments of the present application, in the case that the feedback manner is that the received physical downlink shared channels are fed back at the same time, determines the feedback positions corresponding to all the physical downlink shared channels according to the received first target parameter value, taking the first time slot in which the first physical downlink shared channel is located as a reference, so that the terminal can confirm the feedback positions of each physical downlink shared channel through a smaller DCI overhead in the case of one downlink control information scheduling multiple PDSCHs, and the accurate transmission of feedback information is ensured and the transmission efficiency of data is improved.

[0134] Further, the execution module is configured to group the received PDSCHs in the case that the feedback mode is that the received PDSCHs are fed back at different time instants; and determine the feedback positions corresponding to each group according to the grouping result and the received target parameter value.

[0135] Further, the execution module is configured to group the received PDSCHs according to at least one grouping parameter.
