Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the field of communication technology. BACKGROUND

[0002] A physical downlink shared channel (PDSCH) is a kind of physical downlink channel in a wireless communication system, and is used to carry downlink data. The PDSCH can be scheduled by downlink control information (DCI). The DCI used to schedule the PDSCH includes at least information used to indicate the resources of the PDSCH. In the current new radio (NR) system, multiple DCI formats (formats) used to schedule the PDSCH are defined, such as DCI format 1_0, DCI format 1_1, and DCI format 1_2. The specific information and / or size included in the DCI of different DCI formats are different, in order to meet different scheduling requirements.

[0003] It should be noted that the above introduction to the technical background is only for the convenience of clearly and completely describing the technical solutions of the present application, and for the convenience of understanding by those skilled in the art. The above technical solutions cannot be considered as known to those skilled in the art only because they are described in the background section of the present application. SUMMARY

[0004] In the current NR system, one DCI can only schedule one PDSCH. The inventors have found that in some cases, for a terminal device, this scheduling manner can have a problem of high DCI (PDCCH) monitoring burden, which in turn leads to high complexity and power consumption of the device.

[0005] For example, how to support the NR system to work at higher frequencies (above 52.6 GHz) is currently under study, and data transmission at higher frequencies will face more serious phase noise and other problems. Therefore, in order to overcome the phase noise and other problems, it may be necessary to use a larger subcarrier spacing (e.g. 240 kHz, 480 kHz, 960 kHz, etc.) to support data transmission at higher frequencies, and a larger subcarrier spacing means a shorter symbol length. If the current frame structure design of NR is followed (in which one slot includes 14 symbols), a larger subcarrier spacing means a shorter slot length. On the other hand, if the above scheduling manner is used to support the terminal device (UE) to receive at least one PDSCH in each slot, the UE needs to monitor the DCI in each slot. In this way, in the case of using the above larger subcarrier spacing, the number of DCI monitoring times of the UE in a unit of time will increase due to the shortening of the slot length. That is, the DCI monitoring burden of the UE will increase, and the implementation complexity and power consumption of the UE will also increase accordingly.

[0006] To solve at least one of the above problems, embodiments of the present application provide an information feedback method, an information receiving method and apparatus.

[0007] According to an aspect of embodiments of the present application, an information feedback apparatus is provided, which comprises:

[0009] a second receiving unit configured to receive at least one (N) second PDSCH;

[0010] a first sending unit configured to send first HARQ-ACK information, the first HARQ-ACK information comprising second HARQ-ACK information of the at least one (N) second PDSCH.

[0011] According to another aspect of embodiments of the present application, an information receiving apparatus is provided, which comprises:

[0012] a second sending unit configured to send, to a terminal device, downlink control information (DCI) for scheduling a physical downlink shared channel (PDSCH), the DCI being configured to indicate time domain resource allocation information of at least two (M) first PDSCHs;

[0013] a third sending unit configured to send, to the terminal device, at least one (N) second PDSCH;

[0014] a fourth receiving unit, configured to receive first HARQ-ACK information sent by the terminal device, the first HARQ-ACK information comprising second HARQ-ACK information of the at least one (N) second PDSCH.

[0015] According to another aspect of the embodiments of the present application, a communication system is provided, the system comprising at least a terminal device and a network device, characterized in that

[0016] the terminal device receives downlink control information (DCI) sent by the network device for scheduling a physical downlink shared channel (PDSCH), the DCI being used for indicating time domain resource allocation information of at least two (M) first PDSCHs;

[0018] the terminal device sends first HARQ-ACK information to the network device, the first HARQ-ACK information comprising second HARQ-ACK information of the at least one (N) second PDSCH.

[0019] One of the beneficial effects of the embodiments of the present application is that one DCI can schedule multiple PDSCHs, and a new HARQ-ACK information feedback method is used to support feedback of HARQ-ACK information of multiple PDSCHs scheduled by one DCI, thereby reducing the DCI monitoring burden of the terminal device, and reducing power consumption and complexity.

[0057] The following describes various embodiments.

[0058] Embodiments of the first aspect

[0059] The embodiments of the present application provide an information feedback method, which is described from the terminal device side.

[0060] Figure 2 is a schematic diagram of the information feedback method of the embodiments of the present application, as Figure 2 shown, the method comprises:

[0061] 201, the terminal device receives downlink control information (DCI) for scheduling a physical downlink shared channel (PDSCH), the DCI including a first information field for indicating time domain resources of at least two (M) first PDSCHs;

[0062] 202, the terminal device receives at least one (N) second PDSCH;

[0063] 203, the terminal device transmits first HARQ-ACK information, the first HARQ-ACK information including second HARQ-ACK information of the at least one (N) second PDSCH.

[0064] In some embodiments, the DCI format of the DCI for scheduling the PDSCH can be DCI format 1_0, DCI format 1_1, DCI format 1_2, or a new DCI format introduced in addition, etc., and the embodiments of the present application are not limited thereto.

[0065] In some embodiments, the DCI for scheduling the PDSCH can be scrambled by a cell radio network temporary identifier (C-RNTI), a modulation and coding scheme C-RNTI (MCS-C-RNTI), a configured scheduling RNTI (CS-RNTI), a temporary C-RNTI (TC-RNTI), a system information RNTI (SI-RNTI), a random access RNTI (RA-RNTI), a MsgB-RNTI in a random access response, a paging RNTI (P-RNTI), or a new RNTI introduced in addition, etc., and the embodiments of the present application are not limited thereto.

[0066] In some embodiments, the first PDSCH is the PDSCH indicated by the DCI, which can also be referred to as the indicated PDSCH or the nominal PDSCH, the time domain resources of the at least two (M) first PDSCHs (hereinafter referred to as M first PDSCHs, where M is greater than or equal to 2) are continuous or discontinuous, the number of time domain symbols of different first PDSCHs is the same or different, the time domain resources of each first PDSCH are in one time slot or not, and the embodiments of the present application are not limited thereto.

[0067] In some embodiments, the network device side can configure a list of time domain relationship between PDSCH and PDCCH (or referred to as a first time domain resource allocation table) through high layer signaling, for example, the network device sends an RRC message including first configuration information, the first configuration information includes at least one first information element, wherein one first information element is used to configure the time domain relationship between PDSCH and PDCCH, for example, the first configuration information is PDSCH-TimeDomainResourceAllocationList, the first information element is PDSCH-TimeDomainResourceAllocation, and the first configuration information is included in pdsch-ConfigCommon or pdsch-Config, for example. The first time domain resource allocation table includes at least one row of PDSCH time domain resource configuration, and one row of PDSCH time domain resource configuration corresponds to the above-mentioned first information element.

[0068] In some embodiments, the DCI includes a first information field used to indicate the time domain resource of the at least two (M) first PDSCHs, for example, the time domain resource allocation (Time domain resource assignment) field, the first information field contains a fifth number (E) of bits, which can be configured or predefined, and the application embodiments are not limited thereto, the decimal value corresponding to the fifth number of bits is the value of the first information field, which can be used to indicate which first information element in the first configuration information is indicated by the DCI, for example, the value of the first information field is 0, which corresponds to the first first information element in the first configuration information, the value of the first information field is 1, which corresponds to the second first information element in the first configuration information, and so on. Here, no longer one by one.

[0069] The following further describes how to determine the indicated at least two (M) first PDSCHs (hereinafter referred to as M first PDSCHs, wherein M is greater than or equal to 2) according to the first information field and the first configuration information.

[0070] In some embodiments, in the case where the above-mentioned first information field is used to indicate the time domain resource of the at least two (M) first PDSCHs, the value of the first information field corresponds to one first information element, and the one first information element is used to configure the time domain relationship between the M first PDSCHs and the PDCCH carrying the DCI.

[0071] In some embodiments, the first information element can include at least one second information element (e.g., PDSCH-Allocation or startSymbolAndLength) for configuring time-domain resource (or in other words, symbols of PDSCH, e.g., including starting symbol and length (SLIV)) of PDSCH, the number of second information elements included in each first information element is same or different, in other words, the first information element can include at most a first predetermined value (e.g., maxNrofMultiplePDSCHs) of second information elements, the first predetermined value is predefined and greater than 1; the second information element is used for configuring time-domain resource of one PDSCH, the value of the first information field corresponds to one first information element, the one first information element is used for configuring time-domain relationship between M first PDSCHs and PDCCH carrying the DCI, that is, the one first information element includes at least two (M) second information elements, each second information element is used for configuring time-domain resource of one first PDSCH.

[0072] In the above embodiments, the second information element includes PDSCH mapping type (mappingType) and starting symbol and length (startSymbolAndLength) configuration, that is, the time-domain resource of each first PDSCH is determined by applying the PDSCH mapping type and starting symbol and length configuration in the respective (corresponding to the second information element) second information element; for example, the first configuration information can be represented using abstract syntax notation ASN.1 data format as follows:

[0073]

[0074] Or the second information element includes starting symbol and length configuration (startSymbolAndLength), the first information element includes PDSCH mapping type configuration (mappingType), that is, the time-domain resource of each first PDSCH is determined by applying the respective (corresponding to the second information element) starting symbol and length configuration, but applying the same PDSCH mapping type configuration; for example, the first configuration information can be represented using abstract syntax notation ASN.1 data format as follows:

[0075]

[0076]

[0077] In some embodiments, the first information element can include information (e.g. nrOfPDSCHs) for configuring a sixth number (F) representing the number of the first PDSCHs corresponding to the first information element. In the case that the above-mentioned first information field is used for indicating the time domain resources of at least two (M) first PDSCHs, the value of the first information field corresponds to one first information element, the one first information element is used for configuring the time domain relationship between the M first PDSCHs and the PDCCH carrying the DCI, and the sixth number F included in the one first information element is equal to the above-mentioned M.

[0078] In the above-mentioned embodiments, the first information element includes information (e.g. k0) for configuring the slot offset (K0) between the PDSCH and the PDCCH. For example, k0 indicates the slot offset between the starting time domain position of the F first PDSCHs and the PDCCH, or the slot offset between the first one of the F first PDSCHs and the PDCCH. For example, assuming that the PDCCH carrying the above-mentioned DCI is transmitted in slot n, the starting time domain position of the F first PDSCHs is in slot n+K0, or the first one of the F first PDSCHs is transmitted in slot n+K0. In addition, the first information element can also include information (e.g. mappingType) for configuring the PDSCH mapping type and / or information (e.g. startSymbolAndLength) for configuring the time domain resources of the PDSCH (or the symbols of the PDSCH, e.g. including the starting symbol and length (SLIV) of the PDSCH), for example, the first configuration information can be represented using the Abstract Syntax Notation One (ASN.1) data format as follows:

[0079]

[0080] wherein SEQUENCE represents an ordered set of corresponding information, SIZE represents the number of elements in the corresponding SEQUENCE set, INTEGER() and ENUMERATED() represent the value type and value range of the corresponding information, and specific reference can be made to the ASN.1 syntax, which will not be described here one by one.

[0081] In the above-mentioned embodiments, the same PDSCH mapping type and starting symbol and length can be applied to determine the time domain resources of the F first PDSCHs; or the PDSCH mapping type and starting symbol and length are applied to determine the time domain resources of the first one of the F first PDSCHs, and the time domain resources of the remaining (F-1) first PDSCHs are the same as the time domain resources of the first one of the F first PDSCHs and are sequentially mapped on the continuous symbols.

[0082] In some embodiments, the first information element can include a seventh number (G) of information (e.g. nrOfSlots) indicating the number of slots corresponding to the first information element. The value of the first information field corresponds to a first information element for configuring the time-domain relationship between M first PDSCHs and the PDCCH carrying the DCI, and the seventh number G included in the first information element is M.

[0083] In the above embodiments, the first information element includes information (e.g. k0) for configuring the slot offset (K0) between PDSCH and PDCCH. For example, k0 indicates the slot offset between the starting time-domain position of G first PDSCHs and the PDCCH, or in other words, the slot offset between the first PDSCH of the G first PDSCHs and the PDCCH. For example, assuming that the PDCCH carrying the above DCI is transmitted in slot n, the starting time-domain position of the G first PDSCHs is in slot n+K0, or in other words, the first PDSCH of the G first PDSCHs is transmitted in slot n+K0, in addition, the first information element can also include information (e.g. mappingType) for configuring the PDSCH mapping type and / or information (e.g. startSymbolAndLength) for configuring the time-domain resource of the PDSCH (or in other words, the symbol of the PDSCH, e.g. including the starting symbol and length (SLIV) of the PDSCH), the same PDSCH mapping type and starting symbol and length can be applied to determine the time-domain resource of the G first PDSCHs.

[0084] For example, the first configuration information can be represented using the Abstract Syntax Notation One (ASN.1) data format as follows:

[0085]

[0086] In some embodiments, the network device can also configure the slot offset value (K0) between the plurality of PDSCHs and the PDCCH through high-layer signaling, i.e. the time-domain resource of the M first PDSCHs applies the respective (K0) information to determine the respective time slots. For example, the information of the slot offset (K0) between the PDSCH and the PDCCH can be included in the second information element, and the time-domain resource of the M first PDSCHs applies the respective (K0) information to determine the respective time slots, which will not be exemplified one by one here.

[0087] The above is described by taking an example of the network device side configuring a time domain relationship list of PDSCH and PDCCH (or referred to as a PDSCH time domain resource allocation list) through high-layer signaling, but embodiments of the present application are not limited thereto, for example, a plurality of PDSCH time domain resources can also be configured by predefining a PDSCH and PDCCH time domain relationship list, and one row of configuration is similar to the above-mentioned configuration of one first information element, which will not be described herein again.

[0088] The following further describes how to determine the at least one (N) second PDSCH.

[0089] In some embodiments, the second PDSCH is an actual scheduled PDSCH, the first PDSCH described above is the second PDSCH, N = M, and both N and M are greater than or equal to 2, in other words, the M first PDSCHs indicated by the DCI are the actual scheduled N second PDSCHs.

[0090] In some embodiments, the terminal device can determine the at least one (N) second PDSCH according to at least one of the following information: semi-statically configured transmission direction (or information for semi-statically configuring the transmission direction), configured PRACH resource, information for dynamically scheduling uplink transmission or information for dynamically configuring the transmission direction, configured invalid symbol, and whether to cross slots. The following are described respectively.

[0091] In some embodiments, the semi-static configuration is configured by the base station through high-layer signaling at a cell level / user-specific level. The information for semi-statically configuring the transmission direction is, for example, tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated, and the transmission direction of one time unit (e.g., symbol, slot, subframe) can be semi-statically configured as uplink, downlink, or flexible, wherein the time unit not explicitly configured as uplink or downlink by the above information is configured as a flexible time unit. When determining the N second PDSCHs according to the semi-statically configured transmission direction, when at least one symbol of the first PDSCH is semi-statically configured as uplink (i.e., the PDSCH cannot receive downlink), the first PDSCH is not a second PDSCH, in other words, the terminal device does not receive the first PDSCH. For example, for one slot (assuming that there is one first PDSCH in one slot) of a plurality of slots, if at least one symbol of the first PDSCH indicated by the above-mentioned DCI in the slot is semi-statically configured as uplink, the terminal device does not receive the first PDSCH in the slot. Figure 3Ais at least one second PDSCH pattern, as Figure 3A As shown in FIG. 2, assuming that the first PDSCH in the second slot of the figure has one symbol semi-statically configured as uplink, and other symbols of the figure are not configured as uplink, the first PDSCH is not a second PDSCH.

[0092] In some embodiments, when determining the N second PDSCHs according to the configured PRACH resource, the first PDSCH is not a second PDSCH when at least one symbol of the first PDSCH is configured as PRACH, and / or at least one symbol of the first PDSCH is a symbol in the tenth number (for example, predefined) of symbols (for example, referred to as interval symbols) before the configured PRACH, Figure 3B is at least one second PDSCH pattern, as Figure 3B As shown in FIG. 2, assuming that the first PDSCH in the second slot of the figure has one symbol semi-statically configured as uplink, and other symbols of the figure are not configured as uplink, the first PDSCH is not a second PDSCH.

[0093] In some embodiments, the transmission direction can be dynamically configured by the information for dynamically configuring the transmission direction as uplink, downlink or flexible, wherein the time unit not explicitly configured as uplink or downlink by the information is configured as flexible, when determining the N second PDSCHs according to the information for dynamically scheduling uplink transmission or the information for dynamically configuring the transmission direction, the first PDSCH is not a second PDSCH when at least one symbol of the first PDSCH is dynamically scheduled for uplink transmission by the information or the transmission direction of the first PDSCH is dynamically configured as uplink by the information, in other words, the terminal device does not receive the first PDSCH. The above-mentioned embodiments and the above-mentioned semi-statically configured embodiments will not be repeated here.

[0094] In the above embodiments, the information for dynamically scheduling uplink transmission (for example, DCI of DCI format 0_0 or DCI format 0_1 or DCI format 0_2) or the information for dynamically configuring the transmission direction (for example, DCI of DCI format 2_0) is sent before the DCI, otherwise, the UE does not determine the second PDSCH according to the information, or in other words, does not consider the information when determining the at least one second PDSCH.

[0095] Or, in the above embodiments, the information for dynamically scheduling uplink transmission (e.g. DCI of DCI format 0_0 or DCI format 0_1 or DCI format 0_2) or the information for dynamically configuring transmission direction (e.g. DCI of DCI format 2_0) is sent before a certain time of the DCI (the certain time is e.g. predefined), otherwise, the UE does not determine the second PDSCH according to the information or does not consider the information when determining the at least one second PDSCH.

[0096] In some embodiments, when determining the at least one second PDSCH according to the configured invalid symbol, when at least one symbol of the first PDSCH is configured to be invalid (i.e. cannot receive the PDSCH of the downlink), the first PDSCH is not a second PDSCH, the above-mentioned embodiments are combined with the above-mentioned semi-static configuration embodiments, which will not be repeated here.

[0097] In some embodiments, the terminal device can also determine the invalid symbol according to at least one of the following information: semi-statically configured transmission direction (or information for semi-statically configuring transmission direction), configured PRACH resource, information for dynamically scheduling uplink transmission or information for dynamically configuring transmission direction, configured invalid symbol. For example, the semi-statically configured uplink symbol can be determined to be invalid, and / or the symbol configured with PRACH resource can be determined to be invalid, and / or the symbol in the tenth number (e.g. predefined) of symbols before the PRACH (e.g. called interval symbol) can be determined to be invalid, and / or the symbol dynamically scheduled by the information for dynamically scheduling uplink transmission can be determined to be invalid, and / or the symbol configured to be uplink by the information for dynamically configuring transmission direction can be determined to be invalid, and / or the symbol configured to be invalid can be determined to be invalid. If the first PDSCH contains the determined invalid symbol, the first PDSCH is not a second PDSCH, and the specific embodiments are as described above, which will not be repeated here.

[0098] The factors for determining the at least one (N) second PDSCH or determining the invalid symbol can be implemented alone or in combination, and the embodiments of the present application are not limited in this regard.

[0099] In some embodiments, the value of N does not exceed the maximum number of the first PDSCH corresponding to each of the above-mentioned first information elements, or the value of N does not exceed M. Figure 3C is a schematic diagram of the at least one second PDSCH, assuming that the value of N does not exceed M, as Figure 3CAs shown, the M value is 4, and the number of second PDSCHs N is at most 4. This is only an example, and embodiments of the present application are not limited thereto.

[0100] The following further describes other information fields that the DCI can include.

[0101] In some embodiments, the DCI can further include a fifth information field, which can be a HARQ-ACK timing indicator field, for indicating the feedback timing k of HARQ-ACK information, or the DCI can not include the fifth information field, and the terminal device receives second configuration information (such as dl-DataToUL-ACK or dl-DataToUL-ACKForDCIFormat1_2 for DCI format 1_2) configured by high-layer signaling, for indicating the feedback timing k of HARQ-ACK information.

[0102] In some embodiments, the terminal device transmits the first HARQ-ACK information in a slot with index n+k (slot n+k), where the slot with index n (slot n) is the ending slot of the at least two (M) first PDSCHs or the ending slot of the last first PDSCH in the at least two (M) first PDSCHs, and n and k are integers greater than 0, i.e., the ending slot of the last first PDSCH is n (the downlink ending slot n' of the PDSCH corresponds to an uplink slot index of n), and k is the offset between the feedback slot of the first HARQ-ACK information and the slot n. The relationship between the downlink ending slot n' of the PDSCH and its corresponding uplink slot index n can be determined according to the uplink-downlink subcarrier spacing, and specific details can be referred to in the prior art, which will not be described here. Figure 4A and Figure 4B is a schematic diagram of the first HARQ-ACK information feedback slot, as Figure 4A shown, the M first PDSCHs are actually scheduled N second PDSCHs, the downlink slot in which the last first PDSCH ends is n, and the first HARQ-ACK information is transmitted in slot n+k, as Figure 4B shown, the last first PDSCH is not a second PDSCH, the downlink slot in which the last first PDSCH ends is n, and the first HARQ-ACK information is transmitted in slot n+k, instead of regarding the downlink slot in which the last second PDSCH ends as n.

[0103] In some embodiments, the first HARQ-ACK information is carried by a PUCCH or a PUSCH. The second HARQ-ACK information of the at least one (N) second PDSCH is carried by the same PUCCH or PUSCH.

[0104] In some embodiments, the overall HARQ-ACK information fed back by the terminal device on one physical uplink resource can be referred to as a HARQ-ACK codebook. The terminal device transmits the first HARQ-ACK information using a semi-static HARQ-ACK codebook, or in other words, the first HARQ-ACK information is a semi-static HARQ-ACK codebook, which is also referred to as a Type-1 HARQ-ACK codebook. The size of the codebook does not dynamically change with actual data scheduling, but is determined according to pre-configured (e.g., configured by high-layer signaling) or predefined parameters.

[0105] The following further describes how to generate the first HARQ-ACK information (i.e., how to generate the codebook).

[0106] In some embodiments, the codebook can include HARQ-ACK information bits of one or more serving cells. The following only describes how to determine the HARQ-ACK information bits of one serving cell. In the case where the codebook includes HARQ-ACK information bits of multiple serving cells, the determination manner of the HARQ-ACK information bits of each serving cell is the same as the determination manner of the HARQ-ACK information bits of the aforementioned one serving cell.

[0107] In some embodiments, the codebook includes HARQ-ACK information bits corresponding to the first number (A) of candidate PDSCH reception occasions, and the first number is a natural number. The first number (A) of candidate PDSCH reception occasions corresponds to the same serving cell (i.e., the aforementioned one serving cell), i.e., the first number (A) of candidate PDSCH reception occasions belongs to the candidate PDSCH reception occasion set M of the serving cell. A,c .

[0108] In the prior art, since only one DCI schedules one PDSCH, the current HARQ-ACK information feedback method does not consider the case of one DCI scheduling multiple PDSCHs, and does not support feedback of HARQ-ACK information of multiple PDSCHs scheduled by one DCI. In the embodiments of the present application, one DCI can schedule multiple PDSCHs, in order to support feedback of HARQ-ACK information of multiple PDSCHs scheduled by one DCI, a HARQ-ACK information feedback method is provided, wherein the second HARQ-ACK information of the at least one (N) second PDSCH can correspond to the same candidate PDSCH reception occasion, or correspond to different candidate PDSCH reception occasions. The following will be described respectively.

[0109] I. The second HARQ-ACK information of the at least one (N) second PDSCH can correspond to the same candidate PDSCH reception occasion

[0110] Figure 5 is a schematic diagram of the codebook generation method, as shown in Figure 5 , the method comprises:

[0111] 501, determining a first number of candidate PDSCH reception occasions;

[0112] 502, determining HARQ-ACK information bits corresponding to the first number of candidate PDSCH reception occasions.

[0113] In some embodiments, when one row (i.e. one first information element) of the first time domain resource allocation table corresponds to a fourth number (D) of PDSCH time domain resources (for example, including a plurality of second information elements or including the above-mentioned sixth number or seventh number of information), the candidate PDSCH reception occasion is determined according to one PDSCH time domain resource in the fourth number of PDSCHs. For example, the one PDSCH can be the last PDSCH in the fourth number of PDSCHs, but the present application is not limited thereto, and the fourth number is greater than 1.

[0114] In some embodiments, when one row (i.e. one first information element) of the first time domain resource allocation table corresponds to a fourth number (D) of PDSCH time domain resources (for example, including a plurality of second information elements or including the above-mentioned sixth number or seventh number of information), the candidate PDSCH reception occasion is determined according to at least two (P) PDSCH time domain resources in the fourth number of PDSCHs. For example, the at least two (P) PDSCHs can be the fourth number of PDSCHs, i.e. P=D, but the present application is not limited thereto, and the fourth number is greater than 1.

[0115] The following specifically describes how the above two embodiments determine the candidate PDSCH reception occasion.

[0116] In some embodiments, for the HARQ-ACK information feedback slot n u , according to the time slot timing value K1 set associated with the activated uplink part bandwidth UL BWP, the downlink time slot n D corresponding to each K1 in the K1 set can be determined respectively, wherein K1 represents the offset value of PDSCH relative to the HARQ-ACK information feedback slot n u , the determination of the K1 set can refer to the prior art, and when determining the downlink time slot corresponding to each K1, the subcarrier spacing of the uplink part bandwidth and the downlink part bandwidth can be optionally considered, one K1 can correspond to multiple downlink time slots, which can refer to the prior art, and the embodiments of the present application are not limited thereto.

[0117] In some embodiments, the terminal device determines the first quantity of candidate PDSCH receiving occasions according to the second time domain resource allocation table. For a downlink slot corresponding to one K1, if all rows of the second time domain resource allocation table satisfy the first condition, the downlink slot has no corresponding candidate PDSCH receiving occasion, if at least one row of the second time domain resource allocation table does not satisfy the first condition, the downlink slot has a corresponding candidate PDSCH receiving occasion, or, for a downlink slot corresponding to one K1, if all rows of the second time domain resource allocation table do not satisfy the second condition, the downlink slot has no corresponding candidate PDSCH receiving occasion, if at least one row of the second time domain resource allocation table satisfies the second condition, the downlink slot has a corresponding candidate PDSCH receiving occasion; for example, the first condition can be at least one of the following cases: the corresponding one or at least two fifth PDSCH time domain resources include symbols statically configured as uplink, the corresponding one or at least two fifth PDSCH time domain resources include symbols configured with PRACH, the corresponding one or at least two fifth PDSCH time domain resources include symbols configured as invalid, which cannot be used to schedule the PDSCH corresponding to the downlink slot; the second condition can be at least one of the following cases: the corresponding one or at least two fifth PDSCH time domain resources do not include symbols statically configured as uplink, the corresponding one or at least two fifth PDSCH time domain resources do not include symbols configured with PRACH, the corresponding one or at least two fifth PDSCH time domain resources do not include symbols configured as invalid, which can be used to schedule the PDSCH corresponding to the downlink slot. For each downlink slot corresponding to each K1, whether each downlink slot has a corresponding candidate PDSCH receiving occasion is determined according to the above-mentioned manner respectively, thereby determining the first quantity of candidate PDSCH receiving occasions, wherein the second time domain resource allocation table R is used to determine the first quantity of candidate PDSCH receiving occasions, the second time domain resource allocation table R is determined according to the first time domain resource allocation table, for example, the second time domain resource allocation table includes all configurations or part of the configurations of the first time domain resource allocation table, which will be described in detail later.

[0118] For example, the second time domain resource allocation table includes all configurations of the first time domain resource allocation table, one row of the second time domain resource allocation table corresponds to one row (i.e., one first information element) of the first time domain resource table, and one row of the first time domain resource allocation table corresponds to the fourth quantity (D) of PDSCH time domain resources (for example, including a plurality of second information elements or including the sixth quantity or the seventh quantity of information), one row of the second time domain resource allocation table also corresponds to the fourth quantity of PDSCH time domain resources.

[0119] For the case of "determining the candidate PDSCH receiving occasion according to one PDSCH time domain resource in the fourth quantity of PDSCHs":

[0120] take one of the fourth number of PDSCH time domain resources as a fifth PDSCH time domain resource, determine the candidate PDSCH receiving occasion according to the fifth PDSCH time domain resource, for example, judge whether the fifth PDSCH time domain resource includes a symbol semi-statically configured as uplink or includes a symbol configured with PRACH or includes a symbol configured as invalid or cannot be used to schedule the PDSCH corresponding to the downlink slot, if yes, the row corresponding to the fifth PDSCH satisfies the first condition, if not, the row corresponding to the fifth PDSCH satisfies the second condition, for example, the last one of the fourth number of PDSCH time domain resources can be taken as the fifth PDSCH time domain resource;

[0121] For the case of “determining the candidate PDSCH receiving occasion according to at least two PDSCH time domain resources of the fourth number of PDSCHs”:

[0122] take at least two (P) PDSCH time domain resources of the fourth number of PDSCH time domain resources as P fifth PDSCH time domain resources, determine the candidate PDSCH receiving occasion according to the P fifth PDSCH time domain resources, for example, judge whether any one of the P fifth PDSCH time domain resources includes a symbol semi-statically configured as uplink or includes a symbol configured with PRACH or includes a symbol configured as invalid or cannot be used to schedule the PDSCH time domain resource corresponding to the downlink slot, if yes, the row corresponding to the P fifth PDSCH satisfies the first condition, if not, the row corresponding to the P fifth PDSCH satisfies the second condition. For example, the fourth number of PDSCH time domain resources can all be taken as the P fifth PDSCH time domain resources, but the embodiment is not limited thereto.

[0123] Or, for example, take at least two (P) PDSCH time domain resources of the fourth number of PDSCH time domain resources as P fifth PDSCH time domain resources, determine the candidate PDSCH receiving occasion according to the P fifth PDSCH time domain resources, for example, judge whether each of the P fifth PDSCH time domain resources includes a symbol semi-statically configured as uplink or includes a symbol configured with PRACH or includes a symbol configured as invalid or cannot be used to schedule the PDSCH time domain resource corresponding to the downlink slot, if yes, the row corresponding to the P fifth PDSCH satisfies the first condition, if not, the row corresponding to the P fifth PDSCH satisfies the second condition. For example, the fourth number of PDSCH time domain resources can all be taken as the P fifth PDSCH time domain resources, but the embodiment is not limited thereto.

[0124] For example, the second time domain resource allocation table includes partial configuration of the first time domain resource allocation table, one row of the second time domain resource allocation table corresponds to one row (i.e., one first information element) of the first time domain resource table, and one row of the first time domain resource allocation table corresponds to the fourth number (D) of PDSCH time domain resources (e.g., including a plurality of second information elements or including the sixth number or the seventh number of information described above), and one row of the second time domain resource allocation table corresponds to one PDSCH time domain resource, which is one PDSCH time domain resource in the fourth number of PDSCH time domain resources, for example, the last PDSCH time domain resource in the fourth number of PDSCH time domain resources can be taken as the one PDSCH time domain resource.

[0125] For the case of "determining the candidate PDSCH receiving occasion according to one PDSCH time domain resource in the fourth number of PDSCHs":

[0126] The one PDSCH time domain resource is taken as a fifth PDSCH time domain resource, and the candidate PDSCH receiving occasion is determined according to the one fifth PDSCH time domain resource, for example, it is judged whether the fifth PDSCH time domain resource includes a symbol semi-statically configured as uplink or includes a symbol configured with PRACH or includes a symbol configured as invalid or cannot be used to schedule the PDSCH time domain resource corresponding to the downlink slot whether the first condition or the second condition is met, if yes, the row corresponding to the fifth PDSCH satisfies the first condition, if not, the row corresponding to the fifth PDSCH satisfies the second condition.

[0127] For example, the second time domain resource allocation table includes partial configuration of the first time domain resource allocation table, one row of the second time domain resource allocation table corresponds to one row (i.e., one first information element) of the first time domain resource table, and one row of the first time domain resource allocation table corresponds to the fourth number (D) of PDSCH time domain resources (e.g., including a plurality of second information elements or including the sixth number or the seventh number of information described above), and one row of the second time domain resource allocation table corresponds to at least two (P) fifth PDSCH time domain resources.

[0128] For the case of "determining the candidate PDSCH receiving occasion according to at least two PDSCH time domain resources in the fourth number of PDSCHs":

[0129] The at least two (P) fifth PDSCH time domain resources are P PDSCH time domain resources (P is less than D) in the fourth number of PDSCH time domain resources, and a candidate PDSCH receiving occasion is determined according to the at least two fifth PDSCH time domain resources, for example, it is judged whether each of the at least two fifth PDSCH time domain resources includes a symbol statically configured as uplink or includes a symbol configured with PRACH or includes a symbol configured as invalid or whether the P PDSCH time domain resources corresponding to the downlink slot can be used to schedule the PDSCH time domain resources corresponding to the downlink slot satisfy the first condition or the second condition, if yes, the row corresponding to the P fifth PDSCH satisfies the first condition, if not, the row corresponding to the P fifth PDSCH satisfies the second condition; or it is judged whether at least one of the at least two fifth PDSCH includes a symbol statically configured as uplink or includes a symbol configured with PRACH or includes a symbol configured as invalid or whether the P PDSCH time domain resources corresponding to the downlink slot can be used to schedule the PDSCH time domain resources corresponding to the downlink slot satisfy the first condition or the second condition, if yes, the row corresponding to the P fifth PDSCH satisfies the first condition, if not, the row corresponding to the P fifth PDSCH satisfies the second condition.

[0130] In some embodiments, when determining the first number of candidate PDSCH receiving occasions, the BWP switching occasion can also be considered, for example, if the downlink slot is before the BWP switching and the corresponding uplink slot (i.e., the uplink slot in which the terminal device transmits the first HARQ-ACK information) is after the BWP switching, then the downlink slot has no corresponding candidate PDSCH receiving occasion, in addition, other factors such as UE capability can also be considered when determining the first number of candidate PDSCH receiving occasions, for details, please refer to the prior art, which will not be repeated here.

[0131] The above embodiments illustrate how to determine the first number of candidate PDSCH receiving occasions, in 502, the HARQ-ACK information bits corresponding to the first number of candidate PDSCH receiving occasions are determined, in some embodiments, the number of HARQ-ACK information bits corresponding to a candidate PDSCH receiving occasion is related to the second number (B) and / or the HARQ-ACK binding relationship between PDSCH corresponding to the candidate PDSCH receiving occasion, that is, the terminal device can determine the number of HARQ-ACK information bits corresponding to a candidate PDSCH receiving occasion according to the second number and the binding relationship.

[0132] In some embodiments, the second quantity can be a fourth PDSCH (candidate PDSCH) corresponding to the candidate PDSCH receiving occasion, in other words, the fourth PDSCH (or also called candidate PDSCH) in the embodiments of the present application is used to determine the HARQ-ACK information bits corresponding to the candidate PDSCH receiving occasion, for example, refers to the number of PDSCHs that can be (or can be able to) scheduled by one DCI, but does not mean the number of PDSCHs actually scheduled by the DCI (the second PDSCH) or the number of PDSCHs actually indicated by the DCI (the first PDSCH). The number of HARQ-ACK information bits corresponding to a candidate PDSCH receiving occasion and the second quantity B corresponding to the candidate PDSCH receiving occasion means that the value of the second quantity will affect the value of the number of HARQ-ACK information bits corresponding to the candidate PDSCH receiving occasion. For example, assuming that the number of HARQ-ACK information bits corresponding to a candidate PDSCH receiving occasion is wherein, indicates the number of HARQ-ACK information bits corresponding to one PDSCH, and the number of HARQ-ACK information bits corresponding to a candidate PDSCH receiving occasion and the second quantity B corresponding to the candidate PDSCH receiving occasion means that is equal to the second quantity.

[0133] For example, the second quantity is the maximum number of PDSCHs corresponding to each row in the second time domain resource allocation table or the first time domain resource allocation table. Wherein, when the first information element includes at least two second information elements, for example, when one row of the first time domain resource allocation table or the second time domain resource allocation table corresponds to at least two PDSCH time domain resources, the second quantity is the maximum number of PDSCH time domain resources corresponding to each row; when the first information element includes information of the sixth quantity or the seventh quantity, for example, when one row of the first time domain resource allocation table or the second time domain resource allocation table corresponds to the information of the sixth quantity (or the seventh quantity) configured, the second quantity is the maximum number of the sixth quantity (or the seventh quantity) corresponding to each row. Wherein, the number of HARQ-ACK information bits corresponding to each candidate PDSCH receiving occasion is the same.

[0134] Or, for example, the second quantity is the maximum number of PDSCHs corresponding to each row of the second time domain resource allocation table that satisfies the second condition. Where the first information element includes information of at least two second information elements, for example, one row of the first time domain resource allocation table or the second time domain resource allocation table corresponds to at least two PDSCH time domain resources, the second quantity is the maximum number of PDSCH time domain resources corresponding to each row that satisfies the second condition; where the first information element includes information of the sixth quantity or the seventh quantity, for example, one row of the first time domain resource allocation table or the second time domain resource allocation table corresponds to information of the sixth quantity (or the seventh quantity) configured, the second quantity is the maximum number of the sixth quantity (or the seventh quantity) corresponding to each row that satisfies the second condition. Where the number of HARQ-ACK information bits corresponding to each candidate PDSCH reception occasion is the same or different. The implementation method of whether a row satisfies the second condition is as described above, which will not be repeated here.

[0135] Or, for example, the second quantity is the maximum number of PDSCHs corresponding to each row of the second time domain resource allocation table that satisfies the second condition. Where the first information element includes information of at least two second information elements, for example, one row of the first time domain resource allocation table or the second time domain resource allocation table corresponds to at least two PDSCH time domain resources, the second quantity is the maximum number of PDSCH time domain resources corresponding to each row that satisfies the second condition; where the first information element includes information of the sixth quantity or the seventh quantity, for example, one row of the first time domain resource allocation table or the second time domain resource allocation table corresponds to information of the sixth quantity (or the seventh quantity) configured, the second quantity is the maximum number of the sixth quantity (or the seventh quantity) corresponding to each row that satisfies the second condition. Where the number of HARQ-ACK information bits corresponding to each candidate PDSCH reception occasion is the same or different. The implementation method of whether a row satisfies the second condition is as described above, which will not be repeated here.

[0136] In some embodiments, the HARQ-ACK information bit number corresponding to one candidate PDSCH receiving occasion and the HARQ-ACK bundling relationship between PDSCHs refers to that when there is a HARQ-ACK bundling relationship between at least two fourth PDSCHs (candidate PDSCHs) corresponding to the candidate PDSCH receiving occasion, the HARQ-ACK information bits of the at least two fourth PDSCHs with the bundling relationship are jointly encoded. The joint encoding can be a logical AND operation on the HARQ-ACK information bits corresponding to the PDSCHs with the HARQ-ACK bundling relationship.

[0137] In the above embodiment, when there is the above-mentioned bundling relationship, the number of HARQ-ACK information bits corresponding to one candidate PDSCH receiving occasion will be reduced due to joint encoding.

[0138] In some embodiments, the method can further include (optional, not shown) that the terminal device receives configuration information for configuring the HARQ-ACK bundling relationship between PDSCHs, and the configuration information harq-ACK-PDSCHBundlingPUCCH can be carried by RRC signaling. For example, when the configuration information configures that there is a HARQ-ACK bundling relationship between multiple PDSCHs (each fourth PDSCH corresponding to one candidate PDSCH receiving occasion) that can be scheduled by one DCI, the number of HARQ-ACK information bits corresponding to one candidate PDSCH receiving occasion is equal to the number of HARQ-ACK information bits corresponding to one PDSCH

[0139] For example, as shown in Table 1 below, there is a HARQ-ACK bundling relationship between two fourth PDSCHs (i.e., PDSCH1 and PDSCH2) corresponding to one candidate PDSCH receiving occasion, and the HARQ-ACK information corresponding to one candidate PDSCH receiving occasion is the joint encoded information.

[0140] Table 1

[0141] HARQ-ACK information corresponding to PDSCH1 HARQ-ACK information corresponding to PDSCH2 Joint encoding ACK (1) ACK (1) ACK (1) NACK (0) ACK (1) NACK (0) ACK (1) NACK (0) NACK (0) NACK (0) NACK (0) NACK (0)

[0142] In some embodiments, the number of HARQ-ACK information bits corresponding to one PDSCH The number of HARQ-ACK information bits corresponding to one PDSCH can be determined according to the spatial bundling parameter, the code block group (CBG) configuration parameter, and the supported maximum code word parameter, which can be 1 bit or 2 bits, for example, and details can be referred to the prior art, which will not be described here.

[0143] In some embodiments, the second number corresponding to at least two candidate PDSCH reception occasions in the first number (A) of candidate PDSCH reception occasions is the same or different, and the embodiments are not limited thereto.

[0144] In some embodiments, the above describes how to determine the number of HARQ-ACK information bits corresponding to a candidate PDSCH reception occasion, and the determination manner of the number of HARQ-ACK information bits corresponding to each candidate PDSCH reception occasion in the first number (A) of candidate PDSCH reception occasions is similar (wherein the determination manner of the second number can be different), which will not be described one by one.

[0145] In the prior art, the HARQ-ACK information of a PDSCH corresponds to a candidate PDSCH reception occasion of the codebook, and thus the HARQ-ACK information corresponding to the candidate PDSCH reception occasion is the HARQ-ACK information of the PDSCH. In the embodiments of the present application, since one candidate PDSCH reception occasion can correspond to multiple fourth PDSCHs, for example, the second HARQ-ACK information of at least one (N) second PDSCH can correspond to the same candidate PDSCH reception occasion, after determining the number of HARQ-ACK information bits corresponding to a candidate PDSCH reception occasion, it is still necessary to determine how to arrange the HARQ-ACK information bits corresponding to the candidate PDSCH reception occasion. The HARQ-ACK information bits corresponding to each candidate PDSCH reception occasion in the first number (A) of candidate PDSCH reception occasions are sequentially determined in the same manner, and arranged according to the time sequence corresponding to the candidate PDSCH reception occasion or according to the index of each candidate PDSCH reception occasion, to obtain the HARQ-ACK information bits of one serving cell. The HARQ-ACK information bits of one serving cell can be used as a codebook for feedback.

[0146] In some embodiments, the HARQ-ACK information bits corresponding to the candidate PDSCH reception timing can be arranged in the order of the fourth PDSCH corresponding to the candidate PDSCH reception timing, that is, arranged in the time domain order or index of the fourth PDSCH corresponding to the candidate PDSCH reception timing; for example, starting from the low bit (LSB) of the HARQ-ACK information bits corresponding to the candidate PDSCH reception timing, the HARQ-ACK information bits corresponding to each fourth PDSCH are arranged sequentially in the order of the fourth PDSCH, and the remaining HARQ information bits corresponding to the candidate PDSCH reception timing are set to NACK. For a fourth PDSCH that does not correspond to a second PDSCH (i.e., a candidate PDSCH that does not correspond to an actual scheduled PDSCH), its corresponding HARQ-ACK information bits are set to NACK. Figure 6A and Figure 6B This is a schematic diagram of the bit arrangement for the candidate PDSCH reception timing information, as shown below. Figure 6A As shown, candidate PDSCH reception times 0, 1, and 2 each correspond to two identical fourth PDSCHs (i.e., the number of PDSCHs that can be scheduled by one DCI), and each number is 2. In candidate PDSCH reception time 0, both fourth PDSCHs have corresponding second PDSCHs (i.e., PDSCH1 and PDSCH2). In candidate PDSCH reception time 1, neither fourth PDSCH has a corresponding second PDSCH. In candidate PDSCH reception time 2, both PDSCHs have one corresponding first PDSCH (i.e., PDSCH3) and one corresponding second PDSCH (i.e., PDSCH4). Assuming that the HARQ-ACK information corresponding to a fourth PDSCH is 1 bit, the codebook is {PDSCH1-HARQ, PDSCH2-HARQ, NACK, NACK, NACK, PDSCH4-HARQ}, where PDSCH1-HARQ represents the HARQ-ACK information (NACK or ACK) corresponding to PDSCH1, and so on. Figure 6BAs shown, the candidate PDSCH receiving occasions 0, 1, 2, each of which corresponds to two fourth PDSCHs (i.e. the number of PDSCHs that can be scheduled by one DCI) is the same, and is 2, wherein the two fourth PDSCHs of the candidate PDSCH receiving occasion 0 both have corresponding second PDSCHs (i.e. PDSCH1 and PDSCH2), the two fourth PDSCHs of the candidate PDSCH receiving occasion 1 have no corresponding second PDSCHs, and the two PDSCHs of the candidate PDSCH receiving occasion 2 have one corresponding second PDSCH (i.e. PDSCH3), assuming that the HARQ-ACK information corresponding to one fourth PDSCH is 1 bit, then the codebook is {PDSCH1-HARQ, PDSCH2-HARQ, NACK, NACK, NACK, PDSCH3-HARQ}, wherein the value of the 1 bit is 0, indicating NACK, and the value of the 1 bit is 1, indicating ACK.

[0147] In some embodiments, the HARQ-ACK information bits corresponding to the candidate PDSCH receiving occasion can be arranged in turn according to the order of the second PDSCHs corresponding to the candidate PDSCH receiving occasion, that is, according to the time domain order or index of the second PDSCHs corresponding to the candidate PDSCH receiving occasion; for example, starting from the low bit (LSB) of the HARQ-ACK information bits corresponding to the candidate PDSCH receiving occasion, the HARQ-ACK information bits corresponding to each second PDSCH are arranged in turn according to the order of the second PDSCHs, and the remaining HARQ information bits corresponding to the candidate PDSCH receiving occasion are set as NACK, for example, for Figure 6A As shown, assuming that the HARQ-ACK information corresponding to one fourth PDSCH is 1 bit, then the codebook is {PDSCH1-HARQ, PDSCH2-HARQ, NACK, NACK, NACK, PDSCH4-HARQ}; as Figure 6B As shown, assuming that the HARQ-ACK information corresponding to one fourth PDSCH is 1 bit, then the codebook is {PDSCH1-HARQ, PDSCH2-HARQ, NACK, NACK, PDSCH3-HARQ, NACK}, wherein the value of the 1 bit is 0, indicating NACK, and the value of the 1 bit is 1, indicating ACK.

[0148] In some embodiments, the HARQ-ACK information bits corresponding to the candidate PDSCH reception occasion can be arranged in the order of the first PDSCHs corresponding to the candidate PDSCH reception occasion, or in the time domain order or index of the first PDSCHs corresponding to the candidate PDSCH reception occasion. For example, starting from the least significant bit (LSB) of the HARQ-ACK information bits corresponding to the candidate PDSCH reception occasion, the HARQ-ACK information bits corresponding to each first PDSCH are arranged in the order of the first PDSCHs, and the remaining HARQ-ACK information bits corresponding to the candidate PDSCH reception occasion are set to NACK, where the HARQ-ACK information bits corresponding to the first PDSCHs that are not the second PDSCH are set to NACK, for example, the HARQ-ACK information bits corresponding to the first PDSCHs that are not the second PDSCH are set to NACK. Figure 6A As shown in FIG. 6, assuming that the HARQ-ACK information corresponding to a fourth PDSCH is 1 bit, the codebook is {PDSCH1-HARQ, PDSCH2-HARQ, NACK, NACK, NACK, PDSCH4-HARQ}. Figure 6B As shown in FIG. 6, assuming that the HARQ-ACK information corresponding to a fourth PDSCH is 1 bit, the codebook is {PDSCH1-HARQ, PDSCH2-HARQ, NACK, NACK, PDSCH3-HARQ, NACK}, where the value of the 1 bit is 0, indicating NACK, and the value of the 1 bit is 1, indicating ACK.

[0149] In some embodiments, as described above, in the case where the codebook includes the HARQ-ACK information bits of one serving cell, the HARQ-ACK information bits of the one serving cell are fed back as the codebook, and in the case where the codebook includes the HARQ-ACK information bits of multiple serving cells, the determination manner of the HARQ-ACK information bits of each serving cell is the same as the determination manner of the HARQ-ACK information bits of the one serving cell, but in the specific determination, the first time domain resource allocation table and / or the second time domain resource allocation table, the K1 set, and other parameters corresponding to each serving cell can be the same or different, for example, the above parameters can be configured separately for each serving cell, but this embodiment is not limited thereto. The HARQ-ACK information bits corresponding to each serving cell can be arranged in ascending order of the index of the serving cell to generate the codebook for feedback.

[0150] II. The second HARQ-ACK information of at least one (N) second PDSCH can correspond to different candidate PDSCH reception occasions (i.e., the second HARQ-ACK information of the N second PDSCHs is fed back in the HARQ-ACK information bits corresponding to different candidate PDSCH reception occasions)

[0151] In some embodiments, the downlink slots corresponding to each K1 in the K1 set are determined in the same way as in the aforementioned I, and it is determined whether each downlink slot has a corresponding candidate PDSCH receiving occasion, for example, the candidate PDSCH receiving occasion is determined according to one or at least two fifth PDSCHs in the fourth number of PDSCHs, and the specific implementation is as described above, which will not be repeated here.

[0152] The difference from the aforementioned I is that one candidate PDSCH receiving occasion corresponds to one fourth PDSCH instead of multiple fourth PDSCHs, in order to support the feedback of HARQ-ACK information of multiple PDSCHs scheduled by one DCI, for each downlink slot having a corresponding candidate PDSCH receiving occasion, the number of candidate PDSCH receiving occasions corresponding to one downlink slot is a third number. At least two candidate PDSCH receiving occasions in the third number of candidate PDSCH receiving occasions corresponding to at least one downlink slot in the downlink slots having a corresponding candidate PDSCH receiving occasion correspond to different time slots (or in different time slots).

[0153] In some embodiments, the third number is greater than 1, and / or the third number is related to the ninth number (I) corresponding to the downlink time unit and / or the HARQ-ACK binding relationship between the PDSCH, where the determination method of the ninth number I can refer to the determination method of the second number B, and the configuration method of the binding relationship is as described in I, which will not be repeated here. The third number greater than 1 means that at least one downlink slot in the downlink slots having a corresponding candidate PDSCH receiving occasion corresponds to more than one candidate PDSCH receiving occasion.

[0154] In some embodiments, the third number related to the ninth number means that the third number is greater than or equal to the ninth number, for example, according to the UE capability to determine whether the third number is equal to the ninth number or greater than the ninth number, when the UE does not support receiving more than one PDSCH in one downlink slot, the third number is equal to the ninth number, and when the UE supports receiving more than one PDSCH in one downlink slot, the third number is greater than the ninth number.

[0155] In some embodiments, the third quantity is related to the HARQ-ACK bundling relationship between the PDSCHs, which means that when the fourth PDSCHs corresponding to a candidate PDSCH receiving occasion in one downlink slot have a HARQ-ACK bundling relationship, the third quantity can be reduced, for example, the third quantity can be less than the ninth quantity. For example, when the UE does not support receiving more than one PDSCH in one downlink slot, the third quantity is equal to 1 when the RRC signaling is configured to have a bundling relationship, and the third quantity is equal to the number of rows in the second time domain resource allocation table that do not overlap on the corresponding time domain resources (for example, the time domain resources corresponding to the fifth PDSCH) when the UE does not support receiving more than one PDSCH in one downlink slot, and the RRC signaling is not configured to have a bundling relationship.

[0156] In some embodiments, since one candidate PDSCH receiving occasion corresponds to one PDSCH, the HARQ-ACK information bits corresponding to each candidate PDSCH receiving occasion are arranged in the order of the first quantity of candidate PDSCH receiving occasions to obtain the HARQ-ACK information bits of one serving cell. Wherein, if a candidate PDSCH receiving occasion does not correspond to a second PDSCH, its corresponding HARQ-ACK information bit is set to NACK. As mentioned above, in the case that the codebook includes the HARQ-ACK information bits of one serving cell, the HARQ-ACK information bits of the one serving cell are fed back as the codebook, and in the case that the codebook includes the HARQ-ACK information bits of multiple serving cells, the determination manner of the HARQ-ACK information bits of each serving cell is the same as the determination manner of the HARQ-ACK information bits of the one serving cell, but in the specific determination, the first time domain resource allocation table and / or the second time domain resource allocation table, the K1 set and other parameters corresponding to each serving cell can be the same or different, for example, the above-mentioned parameters can be configured separately for each serving cell, but the present embodiment is not limited thereto. The HARQ-ACK information bits corresponding to each serving cell can be arranged in ascending order of the index of the serving cell to generate a codebook for feedback.

[0157] It is worth noting that the above-mentioned Figure 2 ,5 only schematically illustrates the embodiments of the present application, but the present application is not limited thereto. For example, the execution order between each operation can be appropriately adjusted, and in addition, some operations can be added or some operations can be reduced.
