[0024] Figure 1The following is a schematic diagram showing the structure of a wireless communication system applicable to an embodiment of the present application. The wireless communication system includes a terminal 11 and a network-side device 12. The terminal 11 can also be referred to as a terminal device or a user terminal (UE). The terminal 11 can be a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer) or a notebook computer, a personal digital assistant (PDA), a handheld computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile Internet device (Mobile Internet Device, MID), a wearable device (Wearable Device) or a vehicle-mounted device (VUE), a pedestrian terminal (PUE) and other terminal-side devices.

As long as the same technical effect is achieved, the base station is not limited to a specific technical vocabulary. It should be noted that in the embodiment of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0025] The technical solutions provided by the embodiments of the present application are described in detail below through some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0026] like Figure 2 FIG. 2 is a flow chart of a method 200 for feeding back HAQR-ACK information according to an exemplary embodiment of the present application. The method 200 may be, but is not limited to, executed by a terminal, and may specifically be executed by hardware and / or software installed in the terminal. In this embodiment, the method 200 may include at least the following steps.

[0027] S210: When configured with N carriers, the terminal determines a second HARQ-ACK feedback resource based on the first HARQ-ACK feedback resource and the N carriers.

[0028] In this embodiment, the terminal operates in a carrier aggregation (CA) scenario, and the network side configures N (N≥2, and N is an integer) carriers for the terminal. Among the N carriers, uplink (UL) resources (such as uplink physical uplink control channel (PUCCH) resources) can be configured only on some carriers. For example, among the N carriers configured for the terminal, uplink PUCCH resources can be configured on M (M≤N) carriers. In this case, the network side can be configured to enable PUCCH carrier switching mode, so that the terminal can switch on M carriers configured with PUCCH resources to realize HARQ-ACK information feedback. It should be noted that the time division duplex (TDD) configuration or time slot format of each carrier mentioned in this embodiment and subsequent embodiments can be implemented by protocol agreement or network configuration.

[0029] In addition, the first HAQR-ACK feedback resource can be determined according to the network indication. For example, assuming that the terminal is configured with at least one DL SPS configuration (Configured) resource on carrier CC1, such as SPS config 1~L, and the terminal receives the SPS PDSCH of SPS config j in slot n, then according to the activation DCI indication of SPS config j, the HARQ-ACK information corresponding to the SPS PDSCH will be fed back in slot n+k, that is, the first HAQR-ACK feedback resource determined according to the network indication is slot n+k, where k is determined according to the DCI indication and can be 2, etc.

[0030] Of course, as a possible implementation method, the terminal may perform a step of determining a second HARQ-ACK feedback resource based on the first HAQR-ACK feedback resource and the N carriers when detecting that the first HAQR-ACK feedback resource conflicts with the DL resources of the N carriers. "The first HAQR-ACK feedback resource conflicts with the DL resources of the N carriers" may be understood as: part or all of the symbols occupied by the PUCCH resources used to carry the HARQ-ACK information determined within the first HARQ-ACK feedback time (slot n+k) conflict with DL (including DL symbol, SSB, CORESET#0, etc.) symbols. Of course, for this conflict problem, in this embodiment, the HARQ-ACK information may be postponed to a subsequent time (such as any time after the first HARQ-ACK feedback time) for feedback, and the second HAQR-ACK feedback resource carrying the HARQ-ACK information may be located on any carrier among the N carriers configured with UL resources, thereby achieving normal feedback of the HARQ-ACK information.

[0031] Alternatively, the terminal may also execute the step of determining the second HARQ-ACK feedback resource based on the first HARQ-ACK feedback resource and the N carriers when receiving resource indication information sent by the network side (such as indication information for scheduling new transmission or indication information for scheduling retransmission transmission). This embodiment does not impose any restrictions on this.

[0032] S220: The terminal transmits HARQ-ACK information based on the second HARQ-ACK feedback resource.

[0033] The second HARQ-ACK feedback resource is determined by resource reselection, and the reselected second HARQ-ACK feedback resource can be determined at the first HARQ-ACK feedback time or at any time after the first HARQ-ACK feedback time, and is configured as an available UL resource on any carrier of the N carriers, such as a PUCCH resource. It can be understood that the "available UL resources" mentioned in this embodiment and subsequent embodiments refer to sufficient uplink resources on the carrier or the time unit for transmitting PUCCH, and the PUCCH includes the HARQ-ACK information corresponding to the SPS PDSCH and may also include other uplink control information (Uplink Control Information, UCI). Alternatively, the available UL resources refer to sufficient uplink resources on the carrier or the time unit for transmitting PUSCH, and the PUSCH is a dynamically scheduled or semi-statically configured PUSCH, and UCI (including HARQ-ACK of SPS PDSCH) will be multiplexed and transmitted on PUSCH.

[0034] Optionally, the HARQ-ACK information may refer to the HARQ-ACK information corresponding to a specific PDSCH, or may generally refer to the HARQ-ACK information corresponding to the PDSCH for which HARQ-ACK feedback is required. In addition, the HARQ-ACK information may refer to HARQ-ACK data information, or may refer to HARQ-ACK codebook information, such as type (Type) 1 / 2 / 3 codebook.

[0035] In this embodiment, the terminal determines the second HARQ-ACK feedback resource based on the first HARQR-ACK feedback resource and the N carriers, so as to achieve the purpose of reselecting the HARQ-ACK feedback resource on the N carriers, thereby enabling the terminal to transmit HARQ-ACK information based on the reselected HARQ-ACK feedback resource, thereby effectively avoiding the problem of HARQ-ACK information being discarded due to the conflict between the HARQ-ACK feedback resource and the DL resource, and improving the performance of the SPSPDSCH and the utilization rate of the UL resources on the N carriers.

[0036] like Figure 3 FIG. 1 is a flow chart of a method 300 for feeding back HAQR-ACK information according to an exemplary embodiment of the present application. The method 300 may be, but is not limited to, executed by a terminal, and may specifically be executed by hardware and / or software installed in the terminal. In this embodiment, the method 300 may include at least the following steps.

[0037] S310: When configured with N carriers, the terminal determines a second HARQ-ACK feedback resource based on the first HARQ-ACK feedback resource and the N carriers.

[0038] Where N ≥ 2, and N is an integer.

[0039] It can be understood that, in addition to referring to the relevant description in method embodiment 200 for the implementation process of S310, as a possible implementation manner, the terminal may determine the second HARQ-ACK feedback resource based on the first HARQ-ACK feedback resource and the N carriers in a variety of ways, for example, please refer again to Figure 3 The implementation process of S310 may further include S311 and / or S312, the contents of which are as follows.

[0040] S311: When configured with N carriers, the terminal determines the second HARQ-ACK feedback resource on a first carrier or a first carrier set based on a first time.

[0041] The first time is determined according to the first HARQ-ACK feedback resource. For example, when the first HARQ-ACK feedback resource includes the first HARQ-ACK feedback time, the first time can be the first HARQ-ACK feedback time, or any time after the first HARQ-ACK feedback time.

[0042] For example, assuming that the first time is the first HARQ-ACK feedback time, and the first HARQ-ACK feedback time is a time unit j determined based on the activation DCI, j=n+k, then the terminal may first determine the first carrier or the first carrier set on the time unit j, then search for available UL resources on the first carrier and the first carrier set, and determine the available UL resources as the second HARQ-ACK feedback resources. It should be noted that when determining the first carrier or the first carrier set, if there are multiple carriers, the first carrier or the first carrier set may be selected according to the carrier number, such as in order from small to large (or from large to small).

[0043] Alternatively, assuming that the first time is any time after the first HARQ-ACK feedback time, and the first HARQ-ACK feedback time is the time unit j determined based on the activation DCI, j=n+k, then the first time is j+a, and the terminal can first determine the first carrier or the first carrier set on the time unit j+a, and then search for available UL resources on the first carrier and the first carrier set, and determine the available UL resources as the second HARQ-ACK feedback resources.

[0044] Furthermore, the first carrier belongs to the N carriers, for example, the first carrier may be any one of the N carriers. Optionally, in this embodiment, the first carrier may include at least one of the following (11)-(17).

[0045] (11) The carrier with the smallest number among the N carriers.

[0046] (12) The carrier with the largest number among the N carriers.

[0047] (13) Carrier determined according to the PUCCH cell timing pattern.

[0048] The PUCCH cell timing mode may be implemented through protocol agreement, high-layer configuration, network configuration, etc. In this embodiment, the terminal is configured with one or more PUCCH cell timing modes to indicate whether each carrier is allowed to be used. For example, the PUCCH cell timing mode may indicate carriers that are available or unavailable within a period of time, when each carrier is available and when it is unavailable, etc. In addition, the usage information of the PUCCH carriers indicated by different PUCCH cell timing modes in different cells may be the same or different.

[0049] In one implementation, the first carrier or the first carrier set determined by the terminal according to the PUCCH cell timing mode may be a carrier corresponding to a current time unit in the PUCCH cell timing mode.

[0050] (14) The carrier receiving the PDSCH.

[0051] The PDSCH corresponds to the HAQR-ACK information. Optionally, the PDSCH may be an SPS PDSCH or the like.

[0052] (15) Uplink transmission carrier indicated by the network.

[0053] For example, the network indication may be a DCI indication, and the uplink transmission carrier may be a carrier for transmitting a PUSCH, or a carrier for transmitting a PUCCH, etc.

[0054] (16) Main carrier.

[0055] For example, the primary carrier may be a carrier corresponding to a primary serving cell (PCell) or a carrier corresponding to a primary serving cell (PScell) of a secondary cell group.

[0056] (17) Subcarrier.

[0057] For example, the carrier corresponding to the secondary serving cell (SCell).

[0058] Furthermore, the first carrier set may also include at least one of the following (21)-(26).

[0059] (21) At least some of the N carriers.

[0060] Among them, the at least part of the carriers can be a first number of carriers numbered earlier in the N carriers, or a second number of carriers numbered later in the N carriers, or even-numbered carriers in the N carriers, etc. The first number and the second number can be achieved through protocol agreement, high-level configuration, etc., and are not limited here.

[0061] (22) Carrier determined according to the PUCCH cell timing mode.

[0062] (23) A carrier receiving a PDSCH, wherein the PDSCH corresponds to the HAQR-ACK information.

[0063] (24) The carrier for uplink transmission indicated by DCI.

[0064] (25) Main carrier.

[0065] (26) Subcarrier.

[0066] The implementation process of (22)-(26) can refer to the relevant descriptions in the aforementioned (11)-(17). To avoid repetition, they will not be repeated here.

[0067] It should be noted that the time unit mentioned in this embodiment and subsequent embodiments may be a sub-slot, a time slot, a symbol, a subframe, a frame, a millisecond (ms), a second (s), etc., and is not limited here.

[0068] Further, as a possible implementation method, assuming that the terminal determines the second HARQ-ACK feedback resource on the first carrier set based on the first time, the terminal can determine the second HARQ-ACK feedback resource on each carrier included in the first carrier set in sequence according to the numbering order of each carrier included in the first carrier set.

[0069] For example, assuming that the first time is the first HARQ-ACK feedback time, and the first HARQ-ACK feedback time is a time unit j=n+k determined based on the activation DCI, then the terminal can search for available UL resources on each carrier in the first carrier set in ascending or descending order of carrier numbers based on the time unit j, as the second HARQ-ACK feedback resource.

[0070] S312: When the second HARQ-ACK feedback resource is not determined on the first carrier or the first carrier set, the terminal determines the second HARQ-ACK feedback resource on the first carrier or the first carrier set based on a second time.

[0071] The second time is later than the first time. For example, when the first time is a time unit j=n+k, the second time can be j=n+k+1, j=n+k+2, j=n+k+3, etc.

[0072] As a possible implementation method, assuming that the first time is time unit j, but the terminal has not determined the second HARQ-ACK feedback resource on the first carrier or the first carrier set based on time unit j, then the terminal can continue to determine the second HARQ-ACK feedback resource on the first carrier or the first carrier set based on time unit j+1, and repeat this until the second HARQ-ACK feedback resource is determined on the first carrier or the first carrier set.

[0073] Of course, in order to improve communication efficiency, the second time can be determined according to the maximum delay time, such as the second time can be the same as the maximum delay time or the second time is the sum of the first HARQ-ACK feedback time and the maximum delay time. In this embodiment, the maximum delay time K can be set by protocol agreement, high-level configuration, etc. Def .

[0074] In this case, if the terminal does not determine the second HARQ-ACK feedback resource on the first carrier or the first carrier set based on the second time, but the second time is later than the first time and reaches the maximum delay time, that is, the second time is j+K Def , then, the terminal may stop the step of determining the second HARQ-ACK feedback resource on the first carrier or the first carrier set.

[0075] Based on the description of S311 and S312 above, the process of determining the second HAQR-ACK feedback resource of the terminal on the first carrier and the first carrier set will be described below in combination with method 0 and method 1 respectively.

[0076] Method 0

[0077] (1) The terminal determines the first carrier in slot j (n+k, i.e., the first time in S321), searches for available UL resources on the first carrier, and determines the searched available UL resources as feedback resources for HAQR-ACK information (i.e., second HAQR-ACK feedback resources).

[0078] (2) If the terminal does not find an available UL resource in slot j, the terminal repeats the above (1) in slot j+1 (i.e., the second time in S132) until an available UL resource is found or the maximum delay time is reached, i.e., j=n+k+K Def, then stop searching for available UL resources.

[0079] Method 1

[0080] (1) Starting from slot j (n+k, i.e., the first time in S321), the terminal searches for available UL resources in the first carrier set in ascending or descending order of carrier numbers, and determines the searched available UL resources as feedback resources for HAQR-ACK information (i.e., second HAQR-ACK feedback resources).

[0081] (2) If the terminal does not find available UL resources in the first carrier set in slot j, the terminal repeats the above (1) in slot j+1 (i.e., the second time in S132) until it finds available UL resources or reaches the maximum delay time, i.e., j=n+k+K Def , then stop searching for available UL resources.

[0082] S320: The terminal transmits HARQ-ACK information based on the second HARQ-ACK feedback resource.

[0083] It can be understood that the implementation process of S320 can refer to the relevant description in method embodiment 200, and to avoid repetition, it will not be repeated here.

[0084] Based on the method for feeding back HAQR-ACK information provided in this embodiment, such as the aforementioned method 0 and method 1, the implementation process thereof is further described below with reference to examples.

[0085] Example 1

[0086] like Figure 4a As shown, it is assumed that the terminal receives the SPS PDSCH sent by the network side device on carrier 1 (CC1) and slot n, and according to the network indication (such as activating DCI), the first HARQ-ACK feedback time of the HARQ-ACK information corresponding to the SPS PDSCH is slot n+2 (k=2), and the maximum delay time (i.e., the delay time) of the HARQ-ACK of the SPS PDSCH is K Def =6, that is, the HARQ-ACK information corresponding to the SPS PDSCH can be delayed to be fed back to slot n+2+6 at most.

[0087] In addition, the network side configures PUCCH cell timing pattern 1 and PUCCH cell timing pattern 2. PUCCH cell timing pattern 1 corresponds to slots n to n+3, and the available PUCCH carrier (i.e., the first carrier or the first carrier set) in pattern 1 is CC3. PUCCH cell timing pattern 2 corresponds to slots n+4 to n+7, and the available PUCCH carrier in pattern 2 is CC2.

[0088] In this case, according to the aforementioned method 0, the terminal may first determine the available UL resources for HARQ-ACK information (i.e., the second HARQ-ACK feedback resource) in slot n+2. Since slot n+2 is located in PUCCH cell timing pattern 1, the terminal searches for available UL resources on its corresponding available CC 3. However, since there are no available UL resources in slots n+2 to n+3 on CC 3, the terminal starts searching for subsequent available UL resources on the available CC 2 corresponding to PUCCH cell timing pattern 2, starting from slot n+4. If the terminal finds available UL resources in slot n+4 of CC 2, then HARQ-ACK information can be transmitted based on slot n+4.

[0089] Example 2

[0090] like Figure 4b As shown, it is assumed that the terminal receives the SPS PDSCH sent by the network side device on carrier 1 (CC 1) and slot n, and the first HARQ-ACK feedback time of the HARQ-ACK information corresponding to the SPS PDSCH indicated by the network is slot n+2 (k=2). In addition, the maximum delay time (i.e., the delay time) of the HARQ-ACK of the SPS PDSCH is K Def =8, that is, the HARQ-ACK information corresponding to the SPS PDSCH can be delayed to be fed back to slot n+2+8 at most.

[0091] In addition, the network side configures PUCCH cell timing pattern 1 and PUCCH cell timing pattern 2. PUCCH cell timing pattern 1 corresponds to slots n to n+5, and the available PUCCH carrier in pattern 1 is CC2. PUCCH cell timing pattern 2 corresponds to slots n+6 to n+11, and the available PUCCH carrier in pattern 2 is CC3.

[0092] In this case, according to the aforementioned method 0, the terminal can search for available UL resources on the carrier receiving the SPS PDSCH based on slot n+2. However, because slot n+2 conflicts with DL resources on the carrier receiving the SPS PDSCH, the terminal searches for available UL resources starting from slot n+3 based on the PUCCH cell timing pattern.

[0093] Specifically, slot n+3 is located in PUCCH cell timing pattern 1, so the terminal searches for available UL resources on its corresponding available PUCCH carrier 3. Since there are no available UL resources in slots n+3 to n+5 on CC2, the terminal starts searching for subsequent available UL resources on the available PUCCH carrier CC3 corresponding to PUCCH cell timing pattern 2, starting from slot n+6. Finally, the terminal determines that slot n+9 on CC3 is an available UL resource and transmits HARQ-ACK information.

[0094] Example 3

[0095] like Figure 4c As shown, it is assumed that the terminal receives the SPS PDSCH sent by the network side device on carrier 1 (CC 1) and slot n, and the first HARQ-ACK feedback time of the HARQ-ACK information corresponding to the SPS PDSCH indicated by the network is slot n+2 (k=2). In addition, the maximum delay time (i.e., the delay time) of the HARQ-ACK of the SPS PDSCH is K Def =6, that is, the HARQ-ACK information corresponding to the SPS PDSCH can be delayed to be fed back to slot n+2+6 at most.

[0096] However, since slot n+2 conflicts with DL resources, the terminal postpones the HARQ-ACK information to subsequent UL resources. Based on this, according to the aforementioned method 0, the terminal can search for subsequent available UL resources on the current carrier. If slot n+4 is determined to be an available UL resource, then the terminal transmits the HARQ-ACK information on slot n+4.

[0097] Example 4

[0098] like Figure 4d As shown, it is assumed that the terminal receives the SPS PDSCH sent by the network side device on carrier 1 (CC 1) and slot n, and the first HARQ-ACK feedback time of the HARQ-ACK information corresponding to the SPS PDSCH indicated by the network is slot n+2 (k=2). In addition, the maximum delay time (i.e., the delay time) of the HARQ-ACK of the SPS PDSCH is K Def =6, that is, the HARQ-ACK information corresponding to the SPS PDSCH can be delayed to be fed back to slot n+2+6 at most.

[0099] However, since CC1 conflicts with DL resources in slot n+2, the UE will re-determine the UL resources for HARQ-ACK transmission.

[0100] Based on this, the network schedules PUCCH to be sent in slot n+5 of CC 3 through DCI in slot 3. The PUCCH contains the HARQ-ACK information of the dynamically scheduled PDSCH. Then, according to the aforementioned method 0, the terminal can search for subsequent available UL resources on CC1 (CC1 can be the SPSPDSCH receiving carrier, or the carrier corresponding to the PUCCH cell timing pattern, which is not limited here). There are no available UL resources in slots n+2 to n+4. Therefore, if the terminal switches to CC 3 indicated by DCI in slot n+5 and determines that slot n+5 is an available UL resource, then HARQ-ACK information can be transmitted based on the available UL resources.

[0101] Example 5

[0102] like Figure 4eAs shown, it is assumed that the terminal receives the SPS PDSCH sent by the network side device on carrier 1 (CC 1) and slot n, and the first HARQ-ACK feedback time of the HARQ-ACK information corresponding to the SPS PDSCH indicated by the network is slot n+2 (k=2). In addition, the maximum delay time (i.e., the delay time) of the HARQ-ACK of the SPS PDSCH is K Def =6, that is, the HARQ-ACK information corresponding to the SPS PDSCH can be delayed to be fed back to slot n+2+6 at most.

[0103] In addition, the network side configures PUCCH cell timing pattern 1 and PUCCH cell timing pattern 2. PUCCH cell timing pattern 1 corresponds to slots n to n+4, and the available PUCCH carrier in pattern 1 is CC3. PUCCH cell timing pattern 2 corresponds to slots n+3 to n+7, and the available PUCCH carrier in pattern 2 is CC2.

[0104] In this case, according to the aforementioned method 0, the terminal begins determining HARQ-ACK transmission resources in slot n+2. Since slot n+2 is in PUCCH cell timing pattern 1, the terminal searches for available UL resources on its corresponding available PUCCH carrier 3. Since there are no available UL resources on CC3 in slot n+2, the terminal continues searching for available UL resources in slot n+3. In slot n+3, the available PUCCH carriers include CC3 corresponding to PUCCH cell timing pattern 1 and CC2 corresponding to PUCCH cell timing pattern 2. In ascending order of carrier number, the terminal searches for UL resources on CC2 corresponding to PUCCH cell timing pattern 2 and CC3 corresponding to PUCCH cell timing pattern 1, respectively. Since there are no available UL resources on CC2 or CC3 in slot n+3, the terminal continues searching for available UL resources in slot n+4. Similarly, the available PUCCH carriers corresponding to slot n+4 are CC2 corresponding to PUCCH cell timing pattern 2 and CC3 corresponding to PUCCH cell timing pattern 1, respectively.

[0105] The terminal determines in CC2 that slot n+4 is an available UL resource, and can then transmit HARQ-ACK information based on the available UL resource.

[0106] Example 6

[0107] like Figure 4f As shown, it is assumed that the terminal receives the SPS PDSCH sent by the network side device on carrier 1 (CC 1) and slot n, and the first HARQ-ACK feedback time of the HARQ-ACK information corresponding to the SPS PDSCH indicated by the network is slot n+2 (k=2). In addition, the maximum delay time (i.e., the delay time) of the HARQ-ACK of the SPS PDSCH is K Def =6, that is, the HARQ-ACK information corresponding to the SPS PDSCH can be delayed to be fed back to slot n+2+6 at most.

[0108] In addition, the network side configures PUCCH cell timing pattern 1 and PUCCH cell timing pattern 2. PUCCH cell timing pattern 1 corresponds to slots n to n+4, and the available PUCCH carrier in pattern 1 is CC3. PUCCH cell timing pattern 2 corresponds to slots n+3 to n+7, and the available PUCCH carrier in pattern 2 is CC2.

[0109] In this case, according to the aforementioned method 0, the terminal begins determining the second HARQ-ACK feedback resource in slot n+2. Since slot n+2 is located in PUCCH cell timing pattern 1, the terminal searches for available UL resources on its corresponding available PUCCH carrier 3. Since there are no available UL resources in slot n+2 on CC3, the terminal continues searching for available UL resources in slot n+3.

[0110] In slot n+3, the available PUCCH carriers include CC3 corresponding to PUCCH cell timing pattern 1 and CC2 corresponding to PUCCH cell timing pattern 2. Therefore, the terminal first searches for UL resources on CC2 corresponding to PUCCH cell timing pattern 2. Since there are no available UL resources on CC2 in slot n+3, the terminal continues to search for available UL resources in slot n+4.

[0111] Finally, if the terminal is in CC2 and determines that slot n+4 is an available UL resource, then HARQ-ACK information can be transmitted based on the available UL resource.

[0112] Example 7

[0113] like Figure 4g As shown, it is assumed that the terminal receives the SPS PDSCH sent by the network side device on carrier 1 (CC1) and slot n, and according to the network indication (such as activating DCI), the first HARQ-ACK feedback time of the HARQ-ACK information corresponding to the SPS PDSCH is slot n+2 (k=2), and the maximum delay time (i.e., the delay time) of the HARQ-ACK of the SPS PDSCH is K Def =6, that is, the HARQ-ACK information corresponding to the SPS PDSCH can be delayed to be fed back to slot n+2+6 at most.

[0114] However, since CC1 conflicts with DL resources in slot n+2, the terminal will re-determine the UL resources for HARQ-ACK information transmission. CC1 to CC4 are all uplink carriers configured with PUCCH resources.

[0115] Based on this, according to the aforementioned method 1, the terminal can search for available UL resources for all uplink carriers configured with PUCCH resources in the current slot n+2. Since there are no available UL resources for CC1 to CC4 in slot n+2, the terminal starts searching for available UL resources from slot n+3 (in ascending time order).

[0116] Finally, if the terminal determines that slot n+3 of CC4 is an available UL resource (ie, the second HARQ-ACK feedback resource), then HARQ-ACK information can be transmitted based on slot n+3 of CC4.

[0117] like Figure 5 FIG. 5 is a flow chart of a method 500 for feeding back HAQR-ACK information according to an exemplary embodiment of the present application. The method 500 may be, but is not limited to, executed by a terminal, and may specifically be executed by hardware and / or software installed in the terminal. In this embodiment, the method 500 may include at least the following steps.

[0118] S510: When configured with N carriers, the terminal determines a second HARQ-ACK feedback resource based on the first HARQ-ACK feedback resource and the N carriers.

[0119] Wherein, N≥2, and N is an integer.

[0120] It can be understood that, in addition to referring to the relevant descriptions in method embodiments 200 and / or 300 for the implementation process of S510, as a possible implementation manner, the terminal may determine the second HARQ-ACK feedback resource based on the first HARQ-ACK feedback resource and the N carriers in a variety of ways, for example, please refer again to Figure 5 The implementation process of S510 may include S511 and S512, the contents of which are as follows.

[0121] S511: When N carriers are configured, the terminal determines the second HARQ-ACK feedback resource within a first time set based on the second carrier.

[0122] The first time set may be determined based on the first HARQ-ACK feedback resource. For example, in this embodiment, the first time set may include at least one third time, the third time being the first HARQ-ACK feedback time or any time after the first HARQ-ACK feedback time, wherein the first HARQ-ACK feedback time belongs to the first HARQ-ACK feedback resource.

[0123] Exemplarily, assuming that the first HARQ-ACK feedback time is time unit j determined based on the activation DCI, then the third time can be time unit j+1, time unit j+2, time unit j+3, time unit j+4..., that is, the first time set can include time unit j+1, time unit j+2, time unit j+3, time unit j+4...

[0124] Furthermore, in this embodiment, the second carrier belongs to the N carriers, such as the first carrier can be any one of the N carriers. Optionally, in this embodiment, the second carrier can include at least one of the following (31)-(37).

[0125] (31) The carrier with the smallest number among the N carriers.

[0126] (31) The carrier with the largest number among the N carriers.

[0127] (31) Carrier determined according to the PUCCH cell timing mode.

[0128] (31) A carrier receiving a PDSCH, wherein the PDSCH corresponds to the HAQR-ACK information.

[0129] (31) The carrier for uplink transmission indicated by DCI.

[0130] (31) Main carrier.

[0131] (31) Subcarrier.

[0132] Among them, the implementation process of the above (31)-(37) can refer to the relevant description in the above (11)-(17). To avoid repetition, it will not be repeated here.

[0133] It should be noted that when the terminal determines the second HAQR-ACK feedback resource in the first time set, it can determine the second HAQR-ACK feedback resource on the second carrier in sequence according to the early and late order of the multiple third times included in the first time set.

[0134] S512: If the second HAQR-ACK feedback resource is not determined in the first time set, the terminal determines the second HAQR-ACK feedback resource on a third carrier based on the first time set.

[0135] The third carrier belongs to the N carriers and is different from the second carrier. For example, if the N carriers include carrier (CC) 1, CC2, CC3, and CC4, then when the first carrier is CC1, the third carrier may be any carrier other than CC1, such as CC2, CC3, or CC4.

[0136] Similar to the above method embodiment, in order to improve communication efficiency, the maximum delay time K can be set by protocol agreement, high-level configuration, etc. Def In this case, if the terminal does not find the second HARQ-ACK feedback resource on the second carrier based on the first time set, that is, slot (n+k) to slot (n+k+K def ), then the terminal can exclude the second carrier and continue to reselect the second carrier (ie, the third carrier) to determine the second HARQ-ACK feedback resource in ascending or descending order of the carriers.

[0137] Based on the description of S511 and S512 above, the process of determining the second HAQR-ACK feedback resource of the terminal on the second carrier is described below in combination with method 2.

[0138] Method 2

[0139] (1) The terminal selects a second carrier from the N carriers and, on the second carrier, starts from slot j(n+k) in the first time set to slot (n+k+K def ) ends, searches for available UL resources, and determines the searched available UL resources as feedback resources for HAQR-ACK information (ie, second HAQR-ACK feedback resources).

[0140] (2) If the terminal does not search for available UL resources on the second carrier, that is, the terminal is in slot j to slot j+K def If no available UL resource is found within the search, then the second carrier is excluded, and the terminal may re-determine the second carrier (i.e., the third carrier in S512) among the N carriers in an ascending or descending order, and repeat the above (1) based on the re-determined second carrier until an available UL resource is found.

[0141] S520: The terminal transmits HARQ-ACK information based on the second HARQ-ACK feedback resource.

[0142] It can be understood that the implementation process of S520 can refer to the relevant description in method embodiments 200 and / or 300, and to avoid repetition, it will not be repeated here.

[0143] Based on the method for feeding back HAQR-ACK information provided in this embodiment, such as the aforementioned method 2, its implementation process is further described below with reference to examples.

[0144] Example 1

[0145] like Figure 6 As shown, it is assumed that the terminal receives the SPS PDSCH sent by the network side device on carrier 1 (CC1) and slot n, and according to the network indication (such as activating DCI), the first HARQ-ACK feedback time of the HARQ-ACK information corresponding to the SPS PDSCH is slot n+2 (k=2), and the maximum delay time (i.e., the delay time) of the HARQ-ACK of the SPS PDSCH is K Def =6, that is, the HARQ-ACK information corresponding to the SPS PDSCH can be delayed to be fed back to slot n+2+6 at most.

[0146] However, since slot n+2 conflicts with DL resources, the terminal postpones the HARQ-ACK feedback to subsequent UL resources.

[0147] Specifically, according to the aforementioned method 2, the terminal can search for subsequent available UL resources on the carrier with the smallest number. Since there are no available UL resources in slot n+2 to slot n+8 on CC1, the terminal starts searching for available UL resources from CC2 (in ascending order).

[0148] If the terminal determines available UL resources (ie, second HARQ-ACK feedback resources) in slot n+4 of CC2, then HARQ-ACK transmission can be performed based on the available UL resources.

[0149] Example 2

[0150] See again Figure 4c As shown, it is assumed that the terminal receives the SPS PDSCH sent by the network side device on carrier 1 (CC 1) and slot n, and the first HARQ-ACK feedback time of the HARQ-ACK information corresponding to the SPS PDSCH indicated by the network is slot n+2 (k=2). In addition, the maximum delay time (i.e., the delay time) of the HARQ-ACK of the SPS PDSCH is K Def =6, that is, the HARQ-ACK information corresponding to the SPS PDSCH can be delayed to be fed back to slot n+2+6 at most.

[0151] However, since slot n+2 conflicts with DL resources, according to the aforementioned method 2, the terminal postpones the HARQ-ACK information to the subsequent UL resources. Based on this, the terminal can search for subsequent available UL resources on the current carrier. If slot n+4 is determined to be an available UL resource, then the terminal transmits the HARQ-ACK information on slot n+4.

[0152] Example 3

[0153] like Figure 4d As shown, it is assumed that the terminal receives the SPS PDSCH sent by the network side device on carrier 1 (CC 1) and slot n, and the first HARQ-ACK feedback time of the HARQ-ACK information corresponding to the SPS PDSCH indicated by the network is slot n+2 (k=2). In addition, the maximum delay time (i.e., the delay time) of the HARQ-ACK of the SPS PDSCH is K Def =6, that is, the HARQ-ACK information corresponding to the SPS PDSCH can be delayed to be fed back to slot n+2+6 at most.

[0154] However, since CC1 conflicts with DL resources in slot n+2, the UE will re-determine the UL resources for HARQ-ACK transmission.

[0155] Based on this, the network schedules PUCCH to be sent in slot n+5 of CC 3 through DCI in slot 3. The PUCCH contains the HARQ-ACK information of the dynamically scheduled PDSCH. Then, according to the aforementioned method 2, the terminal can search for subsequent available UL resources on CC1 (CC1 can be the SPSPDSCH receiving carrier, or the carrier corresponding to the PUCCH cell timing pattern, which is not limited here). There are no available UL resources in slots n+2 to n+4. Therefore, if the terminal switches to CC 3 indicated by DCI in slot n+5 and determines that slot n+5 is an available UL resource, then the HARQ-ACK information can be transmitted based on the available UL resources.

[0156] It should be noted that the method 200, 300, or 500 for feeding back HAQR-ACK information provided in the embodiments of the present application may be performed by a device for feeding back HAQR-ACK information, or by a control module in the device for feeding back HAQR-ACK information for performing the method 200, 300, or 500 for feeding back HAQR-ACK information.

[0167] Optionally, the first time set includes at least one third time, where the third time is the first HAQR-ACK feedback time or any time after the first HAQR-ACK feedback time, wherein the first HAQR-ACK feedback time belongs to the first HAQR-ACK feedback resource.
