Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to a transmission method, apparatus, terminal, and network-side equipment. Background Technology

[0002] To improve resource utilization, handover schemes have been proposed. These schemes are used for uplink transmission and are called uplink switching. For uplink switching, the downlink (DL) links of all uplink carriers are always available for transmission to the User Equipment (UE). The UE can determine whether to perform an uplink handover based on the uplink scheduling received from the downlink. However, unlike uplink switching, for downlink switching, the downlink is not always available, including the downlink of the primary cell (PCell). Therefore, the UE cannot monitor all downlink time slots on all component carriers (CCs). It is evident that there is currently no corresponding solution in related technologies for how to perform transmission in downlink handover scenarios. Summary of the Invention

[0051] For ease of understanding, the following describes some aspects of the embodiments of this application:

[0052] Throughout the development of carrier aggregation technology, operators have maintained a high level of attention to aggregating low-frequency band spectrum, including in LTE and NR specifications. Some operators previously submitted a proposal in RP-241537, raising the following questions:

[0053] Some operators possess substantial mid-band spectrum (approximately 300MHz), which performs well near their sites. However, these operators have limited low-band spectrum (15MHz), despite its longer propagation distance. Customers spend more time within low-band coverage areas when moving between sites in urban and rural areas. Low-band carries a significant amount of traffic in both urban and rural areas. On average, these operators' customers spend 15% of their time in urban low-band and 50% in rural low-band each day. Low-band capacity limitations have a significant impact on customer experience. Due to low-band congestion, users will experience slower data rates.

[0054] Low-band carrier aggregation (CA) is a potential solution, but original equipment manufacturers (OEMs) face challenges in supporting it, and the ecosystem is currently underdeveloped. Therefore, considering the current state of existing mobile phone RF front-end architectures, operators have requested 3GPP to study and develop solutions based on handover schemes to accommodate relevant limitations, such as the proposal adopted in RP-243317, which will study the following:

[0055] This section describes the physical layer procedures and requirements for enabling low-frequency band carrier aggregation via handover, with the following specific objectives:

[0056] - Specify UE requirements, including at least a handover interval (if necessary), and the corresponding physical layer procedures, to allow handover between {Scenario 1 (case 1), Scenario 2 (case 2)}:

[0057] -case1: Transmission / reception is performed on Frequency Division Duplexing (FDD) carrier 1, while reception is not performed on Supplemental Downlink (SDL) carrier 2.

[0058] -case2: Reception is performed on SDL carrier 2, while no transmission / reception is performed on FDD carrier 1;

[0059] -RAN1 specifies a semi-static handover pattern only according to Radio Resource Control (RRC) configuration, and coordinates with RAN2 and RAN4 as necessary;

[0060] - Specifies the delay and time mask for carrier switching;

[0061] - Specify the necessary Radio Resource Management (RRM) requirements;

[0062] - Define the corresponding user equipment capabilities;

[0063] - Consider the following deployment constraints:

[0064] - The carrier frequency is <1GHz in all cases;

[0065] - The network deployment of two carriers is co-located and synchronous;

[0066] - The two carriers are located in the same Time Advance Group (TAG) (single TAG);

[0067] - The subcarrier space (SCS) between the two carriers is 15 kHz.

[0068] The above handover-based solution is advantageous in the following two scenarios:

[0069] Scenario 1 (see Figure 2aDue to the proximity of downlink and uplink spectrum, some frequency band combinations cannot be paired, such as n12-n29, n26-n106, and n28-n67. Filter-based solutions are not feasible in these situations. For example, band n29 lies within the duplex gap of band n12, leaving only a 1MHz filter stopband between the uplink (UL) of n12 and the downlink (DL) of n29. There is only a 2MHz gap between the DL of band n26 and the UL of band n106. The DL of band n67 overlaps with the UL of n28. Based on current duplexer technology, solutions based on traditional carrier aggregation architectures are not feasible. Therefore, a handover-based solution can utilize the downlink of band n29.

[0070] Scenario 2 (see Figure 2b In Scenario 2, some frequency band combinations are geographically distant. For example, combining bands n5 and n29, or n14 and n29, or n71 and n29 using a single antenna. While this frequency separation usually doesn't pose design challenges, optimizing the radiation performance of both bands simultaneously can be challenging due to their frequency separation. Adding antenna elements to support these combinations increases cost and RF architecture complexity. Therefore, a handover-based solution can utilize the downlink of the n29 band.

[0071] II. Semi-persistent Scheduling (SPS) and Hybrid Automatic Repeat Request Acknowledgment (HARQ-ACK) Feedback on the Physical Downlink Shared Channel (PDSCH)

[0072] In NR R15, a UE can be configured with at most one SPS PDSCH, and the UE does not expect to send HARQ-ACK messages for more than one SPS PDSCH in a single time unit. In a certain time unit n, if an SPS PDSCH configuration (e.g., via IE SPS-config) is activated and the UE is configured to receive an SPS PDSCH, the UE must send HARQ-ACK messages for that SPS PDSCH in time unit n+k1. However, for the SPS PDSCH in time unit n, the UE may not receive it for various reasons, such as the SPS PDSCH being overridden by a Dynamic Grant (DG) PDSCH or the SPS PDSCH being configured on a semi-static flexible symbol, and that flexible symbol being indicated as a UL symbol by the Slot Format Indicator (SFI).

[0073] In NR R16, a UE can be configured with multiple SPS PDSCHs, and the UE can feed back multiple HARQ-ACK messages corresponding to one or more SPS PDSCH configurations within a single time unit. The UE constructs the HARQ-ACK codebook according to the serving cell index of the SPS PDSCH in ascending order, the SPS PDSCH configuration index in ascending order, and the SPS PDSCH reception time in ascending order. To reduce the number of HARQ-ACK bits, during the HARQ-ACK codebook construction for SPS PDSCHs, the UE does not feed back HARQ-ACK information for SPS PDSCHs that meet certain conditions. For example, SPS PDSCHs determined not to need UE reception during SPSPDSCH overlap processing, or SPSPDSCHs overlapping with the UL symbols of semi-static configurations (such as tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated), do not require UE to feed back their HARQ-ACK information.

[0074] NR also introduces Discontinuous Transmission (DTX) for cells. For each serving cell configured with cell DTX, if cell DTX operation is active but outside the cell DTX activation period, the Media Access Control (MAC) entity does not need to instruct the physical layer to receive transport blocks on the downlink shared channel (DL-SCH) of that serving cell according to the downlink allocation configured for SPS. That is, it does not need to receive SPS PDSCH at the SPS PDSCH resource location, nor does it need to detect the Physical Downlink Shared Channel (PDCCH) scrambled with a specific Radio Network Temporary Identity (RNTI). Therefore, during SPS PDSCH overlap processing, the UE determines whether the SPS PDSCH overlaps with the non-active period of cell DTX. Overlap processing is performed on SPS PDSCHs that do not overlap with the non-active period of cell DTX to determine the SPS PDSCH the UE should receive. When determining the SPS PDSCH HARQ-ACK feedback, only the SPS PDSCH HARQ-ACK that overlaps with the active period of cell DTX is fed back, and the SPS PDSCH HARQ-ACK that overlaps with the inactive period of cell DTX is not fed back.

[0075] III. Type 1 codebook construction method

[0076] The entire HARQ-ACK message fed back by the UE on a HARQ-ACK feedback resource (Physical Uplink Control Channel (PUCCH) or Physical Uplink Sharing Channel (PUSCH)) is called the HARQ-ACK codebook. There are two types of downlink transmissions that require HARQ-ACK message feedback:

[0077] 1. PDSCH;

[0078] 2. Specific PDCCHs without scheduled PDSCHs, such as PDCCHs used for Down Link (DL) SPS PDSCH release, PDCCHs used to indicate Scell ​​dormancy, or PDCCHs used to indicate Transmission Configuration Indication state (TCI state) updates.

[0079] The size of the HARQ-ACK semi-static codebook (also known as the type 1 codebook) is independent of the actual scheduling and is determined by the RRC configuration or predefined parameters. When the RRC parameter pdsch-HARQ-ACK-Codebook = semi-static, it is configured as a semi-static codebook, also known as a type 1 codebook.

[0080] The determination of the HARQ-ACK semi-static codebook is related to the timing parameter set K1. The timing parameter set K1, also known as the feedback timing value set or K1 set, contains a timing parameter k1 that represents the slot / sub-slot offset between the PDSCH or PDCCH and its corresponding feedback resource (PUCCH / PUSCH). A possible set of k1 is configured or predefined by Radio Resource Control (RRC), and a value is indicated by a field in the corresponding Downlink Control Information (DCI) of the PDSCH.

[0081] For example, determining the HARQ-ACK semi-static codebook includes the following steps:

[0082] Step S1: Determine the candidate PDSCH reception timing set: For a specified HARQ ACK feedback actual time unit (e.g., slot / sub-slot n), the set of all downlink data requiring HARQ ACK feedback, including the active downlink bandwidth part (BWP) and uplink BWP in each serving cell. This is determined by the following parameters:

[0083] a) Activate the set of time slot timing values ​​associated with the uplink BWP (i.e., the K1 set).

[0084] For example, if the UE is configured to detect DCI format 1-0 on serving cell c and is not configured to detect DCI format 1-1, then the K1 set is {1, 2, 3, 4, 5, 6, 7, 8}.

[0085] If the UE is configured to detect DCI format 1-1 on serving cell c, the K1 set is provided by the higher-layer parameter dl-DataToUL-ACK.

[0086] b) The set of row indexes for the Time Domain Resource Allocation (TDRA) table. For example, the table in set 1 is the one that activates the downstream BWP association. It is configured by the time domain allocation parameter pdsch-TimeDomainAllocationList in pdsch-ConfigCommon or the default TDRA table, or a joint indication of set 1 and set 2. Set 2 is configured by the time domain allocation parameter pdsch-TimeDomainAllocationList under the higher-level pdsch-Config. The TDRA table may include K0, Start and Length Indication Value (SLIV), and PDSCH mapping type.

[0087] It is important to note that this step also depends on whether the UE is capable of receiving multiple PDSCHs in one slot. If the UE is not capable of receiving multiple PDSCHs, then each slot can have at most one PDSCH reception occasion. Otherwise, it will be determined according to certain rules based on the TDRA table.

[0088] c) The ratio of subcarrier space (SCS) for activating uplink and downlink BWPs.

[0089] d) High-level Time Division Duplex (TDD) uplink and downlink configuration parameters: such as the tdd-UL-DL-ConfigurationCommon parameter and the tdd-UL-DL-ConfigurationDedicated parameter, which are used to indicate which symbols are uplink, which symbols are downlink, and which symbols are flexible symbols.

[0090] Specifically, based on the set of time slot timing values ​​associated with the uplink activated BWP (i.e., the K1 set), the candidate time slot positions of PDSCH are obtained; compared with the uplink and downlink configurations of TDD, the candidate time slot positions of PDSCH are determined to be valid; based on the TDRA table associated with the activated downlink BWP, rows with non-overlapping time domain resources are obtained, and for overlapping rows, only one row is considered, that is, overlapping rows correspond to the same candidate PDSCH reception position.

[0091] For example, assuming the K1 set configured by RRC is {5,6,7}, the TDRA table of PDSCH is as follows: Figure 3a As shown in the diagram. Here, RIX represents the row with index X, where X is a non-negative integer.

[0092] For example, step S1 may include steps S11 and S12.

[0093] Step S11: Determine the feedback window for HARQ-ACK based on the K1 set. For example... Figure 3b As shown, assuming the uplink and downlink subcarrier spacing is the same, the HARQ ACK feedback time unit is slot n+9, and the corresponding PDSCH candidate slot positions are slot n+2, slot n+3, and slot n+4. Among these, in... Figure 3b In the middle, the left diagonal line filled part is the down-line symbol, the white filled part is the (Flexible) symbol, and the small dot filled part is the up-line symbol.

[0094] Step S12: For each k1 value, determine the set of candidate PDSCH reception opportunities within each slot. This specifically includes steps S121 and S122.

[0095] Step S121: Exclude candidate PDSCH reception opportunities that overlap with the uplink symbols configured in the TDRA table and TDD-UL-DL-ConfigurationCommon and TDD-UL-DL-ConfigDedicated.

[0096] Step S122: For overlapping candidate PDSCH reception opportunities, only one HARQ-ACK bit position is generated.

[0097] Specifically, first find the row with the smallest end symbol in the TDRA table (note that the rows in the TDRA do not include those overlapping with the UL symbols of the TDD uplink and downlink configurations). Assume the smallest end symbol is m. Then, iterate through all rows in the table. If the start symbol (let's say s) of a row is less than or equal to m (i.e., s <= m), then that row corresponds to the same candidate PDSCH receive position as the row with the smallest end symbol. Exclude rows in the TDRA that correspond to the same candidate PDSCH receive position. Repeat the above steps until the PDSCH receive positions corresponding to all rows are determined.

[0098] Specifically, such as Figure 4a and Figure 4b As shown, for the case where k1 = 7, for example, as Figure 3bAs shown, the candidate PDSCH slot is located at slot n+2, which consists entirely of downlink symbols. Since the reception timing of all candidate PDSCHs does not conflict with uplink symbols, they can all be retained. It should be noted that... Figure 4a In this context, D represents the DL symbol.

[0099] like Figure 5a and Figure 5b As shown, for the case where k1 = 6, for example, as Figure 3b As shown, the candidate PDSCH slot position is slot n+3, which includes downlink symbols, flexible symbols, and uplink symbols. The candidate PDSCH positions in rows 2, 3, and 8 of the TDRA table overlap with the uplink symbols and are therefore excluded. It should be noted that in... Figure 5a In this symbol, D represents DL, F represents Flexible, and U represents UL.

[0100] For the case where k1 = 5, for example, ... Figure 3b As shown, the candidate PDSCH slot position is slot n+4, which is an uplink symbol. All candidate PDSCH reception timing sets overlap with the uplink symbols, so they are all excluded.

[0101] Therefore, the set of candidate PDSCH reception opportunities is: M A,c ={0,1,2,3,4,5,6,7,8}.

[0102] Step S2: Determine the HARQ-ACK codebook based on the above candidate PDSCH reception timing set.

[0103] It should be noted that when the UE is configured with downlink CA, the HARQ-ACK information of different serving cells in the HARQ-ACK codebook can be concatenated in ascending order of the serving cell index.

[0104] IV. SPS PDSCH HARQ-ACK Deferral

[0105] The HARQ-ACK feedback of SPS PDSCH is timed by the activation of Downlink Control Information (DCI). PUCCH resources are selected from pre-configured PUCCH resources based on the number of bits of the HARQ-ACK feedback. Since the base network side equipment does not have flexible control over the SPS PDSCH HARQ-ACK feedback resources, there may be scenarios where PUCCH resources cannot be transmitted. For example, PUCCH resources may overlap with DL symbols configured for TDD uplink and downlink, or with Synchronous Signal Block (SSB) symbols, or with Control Resource Set (CORESET) symbols associated with Type 0 Common Search Space (CSS set).

[0106] To increase the chance of the UE transmitting SPS PDSCH HARQ-ACK, the UE can be configured to delay the feedback of SPS PDSCH HARQ-ACK. Specifically, when the UE is configured with SPS HARQ delay (such as sps-HARQ-Deferral), if, within the first slot, the UE determines a PUCCH resource configured by a higher layer for feedback of SPS PDSCH HARQ-ACK, for example, a PUCCH resource configured by the SPS-PUCCH-AN-List parameter or the n1PUCCH-AN parameter, feedback of SPS PDSCH HARQ-ACK information (first HARQ-ACK information) on the PUCCH resource, and the PUCCH is not canceled due to overlap with a higher priority indexed PUCCH or PUSCH, and the PUCCH resource is associated with a semi-statically configured UL symbol (such as a UL symbol configured by the tdd-UL-DL-ConfigurationCommon parameter or the tdd-UL-DL-ConfigDedicated parameter) or an SSB symbol (such as one indicated by ssb-PositionsInBurst) or an associated Type 0-PDCCH, then... If the CORESET symbols of the CSS set overlap, the UE determines the earliest second time slot to feed back the second HARQ-ACK information in the first HARQ-ACK information. The value of sps-HARQ-Deferral configured in the SPS PDSCH configuration corresponding to the second HARQ-ACK information is greater than or equal to a time difference, which can be the time difference between the first time slot and the second time slot.

[0107] The transmission method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0108] Please see Figure 6 , Figure 6 This is a flowchart of a transmission method provided in an embodiment of this application. This method can be executed by a terminal, such as... Figure 6 As shown, it includes the following steps:

[0109] Step 601: The terminal receives first configuration information from the network-side device. The first configuration information is used to configure at least one of the following: a switching pattern, an effective time of a first object, and an ineffective time of a first object. The switching pattern is used to indicate the cell, carrier, or scenario in which the terminal operates in at least one time unit in the time domain. The carrier or cell in which the terminal operates is different under different scenarios. The first object includes at least one cell, carrier, or scenario in which the terminal is configured or activated.

[0110] In this embodiment, the switching pattern can also be referred to as a switching mode, carrier or scene operating mode, downlink switching mode, downlink carrier switching mode, or downlink scene switching mode, etc. The time unit can include at least one symbol, at least one time slot, at least one sub-time slot, or at least one subframe, etc. The scene can reflect the carrier on which the terminal operates; different scenes result in different carriers, frequency bands, or frequency domain ranges on which the terminal operates. For example, the scene can include scene 1 and scene 2. In scene 1, uplink transmission with one antenna and downlink reception with two antennas (1Tx / 2Rx) can be performed on carrier 1, while there is no uplink transmission or downlink reception on carrier 2 (0Tx / 0Rx). In scene 2, there is no uplink transmission or downlink reception on carrier 1 (0Tx / 0Rx), while downlink reception with only two antennas (0Tx / 2Rx) can be performed on carrier 2. It is understandable that when the terminal is working in scenario 1, the UE only needs to transmit (TX) / receive (RX) on carrier 1 and does not need to perform RX on carrier 2; when the terminal is working in scenario 2, the terminal only needs to perform RX on carrier 2 and does not need to perform TX / RX on carrier 1.

[0111] It should be noted that scenarios 1 and 2 above are only examples of downlink handover scenarios. The embodiments of this application can also be applied to other downlink carrier handover scenarios, and are not limited to scenarios 1 and 2 above.

[0112] It should be noted that although the embodiments in this application refer to it as downlink handover, downlink carrier handover, downlink cell handover, or downlink scenario handover, if the carrier / cell / scenario involved in the handover is an FDD frequency band, then since the FDD uplink frequency band / cell is coupled, when the UE switches the downlink carrier / cell / scenario, the corresponding uplink carrier / cell / scenario will also switch. For example, in the above scenarios 1 and 2, scenario 1 can have both uplink and downlink transmissions, while scenario 2 can only have downlink transmissions.

[0113] The effective time of the aforementioned cell, carrier, or scenario can also be referred to as the dwell time, working time, or activation time of the aforementioned cell, carrier, or scenario. The ineffective time of the aforementioned cell, carrier, or scenario can also be referred to as the non-dwell time, non-working time, or inactive time of the aforementioned cell, carrier, or scenario. It is understood that for a cell, carrier, or scenario operating within a single time unit, that time unit can be considered the effective time for that cell, carrier, or scenario; correspondingly, that time unit is the ineffective time for other cells, other carriers, or other scenarios. For example, if the cell, carrier, or scenario operating in time unit 1 is cell 1, carrier 1, or scenario 1, then time unit 1 is the effective time for cell 1, carrier 1, or scenario 1, and time unit 1 is the ineffective time for other cells, other carriers, or other scenarios other than cell 1, carrier 1, or scenario 1.

[0114] Optionally, for downlink transmissions, such as SPS PDSCH, the invalid time can be considered as a semi-static uplink symbol. In this case, the transmission of downlink transmissions during the invalid time is handled in the same way as the transmission of downlink transmissions in the semi-static configured uplink symbols. For example, HARQ-ACK corresponding to SPS PDSCH is not opposed, and line indices overlapping with it are excluded when constructing the type 1 codebook. Alternatively, for uplink transmissions, the invalid time can be considered as a semi-static downlink symbol. In this case, the transmission of uplink transmissions during the invalid time is handled in the same way as the transmission of uplink transmissions in the semi-static configured downlink symbols. For example, the corresponding uplink transmission is not sent.

[0115] The aforementioned handover pattern can be used to indicate the cell, carrier, or scenario in which the terminal operates in at least one time unit in the time domain. In an optional implementation, the network-side device can configure the cell, carrier, or scenario in which the terminal operates in each time unit in the time domain. In this case, the aforementioned handover pattern can be used to indicate the cell, carrier, or scenario in which the terminal operates in each time unit in the time domain, for example, as shown in... Figure 7As shown, the network-side device configures which cell, carrier, or scenario the terminal operates on in different time units in the time domain. In another optional implementation, the network-side device can configure only the cell, carrier, or scenario the terminal operates on in some time units in the time domain, while the remaining time units can operate on other cells, carriers, or scenarios according to regulations or rules. For example, the network-side device only configures which time units the terminal operates on in cell 1, carrier 1, or scenario 1, while the remaining time units are configured by default for cell 2, carrier 2, or scenario 2.

[0116] For example, when a terminal receives a handover pattern, it can determine at least one of the effective time and ineffective time of each cell, carrier, or scenario based on the handover pattern, and then perform at least one of uplink transmission and downlink reception based on at least one of the effective time and ineffective time of each cell, carrier, or scenario.

[0117] The effective time and ineffective time of at least one cell, carrier, or scenario in which the terminal is configured or activated may include at least one of the effective time and ineffective time of each cell, carrier, or scenario in which the terminal is configured or activated; or, it may include at least one of the effective time and ineffective time of some cells, carriers, or scenarios in which the terminal is configured or activated. For example, it may only include at least one of the effective time and ineffective time of the cells, carriers, or scenarios in which the terminal is configured or activated for downlink handover or participates in downlink handover. For example, if the UE is configured with CA in three cells, namely cell0, cell1, and cell2, and handover only occurs between cell0 and cell2, with cell1 not participating in handover, in this case, only at least one of the effective time and ineffective time of cell0 and cell2 may be configured, while at least one of the effective time and ineffective time of cell1 may not be configured.

[0118] In some optional embodiments, the handover time may be included within the effective time of a cell, carrier, or scenario. In this case, only the effective time and ineffective time of the cell, carrier, or scenario are included in the time domain. In other optional embodiments, the handover time may not be included within the effective time of any single cell, carrier, or scenario. In this case, the handover time is included in the time domain in addition to the effective or ineffective time of the cell, carrier, or scenario. Here, the aforementioned handover time refers to the time used for cell, carrier, or scenario handover.

[0119] For example, network-side devices can configure first configuration information for terminals via RRC signaling.

[0120] In this embodiment, during downlink carrier handover, the UE can switch between different scenarios (cases). This can be achieved by configuring a semi-static carrier handover pattern using RRC. The UE determines the carrier / cell / case to operate in at least one time unit or the effective time for each carrier / cell / case based on the semi-statically configured handover pattern. For example, the UE determines, based on the first configuration information configured by RRC, to operate in case 1 within time unit n and in case 2 within time unit m, where n is not equal to m. Case 1 and case 2 can be as follows:

[0121] Case 1: Transmission / reception (TX / RX) is performed on FDD carrier 1 (carrier 1), while reception (RX) is not performed on SDL carrier 2 (carrier 2);

[0122] Case 2: Receive (RX) on SDL carrier2, but do not transmit / receive (TX / RX) on FDD carrier1.

[0123] Specifically, when the UE is operating in case 1, the UE only needs to perform TX / RX on carrier 1 and does not need to perform RX on SDL carrier 2; when the UE is operating in case 2, the UE only needs to perform RX on SDL carrier 2 and does not need to perform TX / RX on carrier 1.

[0124] Step 602: The terminal performs HARQ-ACK information feedback processing based on the first configuration information.

[0125] For example, the above-mentioned HARQ-ACK information feedback process may include, but is not limited to, determining whether to feed back HARQ-ACK information, determining whether to delay feeding back HARQ-ACK information, determining the time unit for delaying the feeding back HARQ-ACK information, and constructing the HARQ-ACK codebook.

[0126] In this step, the terminal can provide HARQ-ACK information feedback based on the first configuration information. For example, the terminal can obtain at least one of the valid time and invalid time of the first object based on the first configuration information, and then provide HARQ-ACK information feedback based on at least one of the valid time and invalid time of the first object. For example, the terminal can determine whether to provide HARQ-ACK information corresponding to the SPS PDSCH based on whether the reception time of the SPS PDSCH is within the valid time of its corresponding cell / carrier / scenario, or whether it overlaps with the invalid time of its corresponding cell / carrier / scenario. Alternatively, the terminal can determine whether to delay the feedback of the HARQ-ACK information, or to which time unit to delay the feedback, based on whether the time domain resources of the HARQ-ACK information feedback are within the valid time of its corresponding cell / carrier / scenario, or whether they overlap with the invalid time of its corresponding cell / carrier / scenario.

[0127] In this embodiment, the terminal receives first configuration information from a network-side device. This first configuration information configures at least one of the following: a handover pattern, a valid time for a first object, and an invalid time for the first object. The handover pattern indicates the cell, carrier, or scenario in which the terminal operates in at least one time unit in the time domain. The carrier or cell in which the terminal operates differs under different scenarios. The first object includes at least one cell, carrier, or scenario in which the terminal is configured or activated. HARQ-ACK information feedback is then performed based on the first configuration information. Since at least one of the valid and invalid times of the first object can be known based on the first configuration information, performing HARQ-ACK information feedback based on the first configuration information when the terminal is configured for downlink handover helps reduce invalid HARQ-ACK information feedback, thereby reducing the terminal's power consumption and improving the effectiveness of the communication system.

[0128] Optionally, the terminal performs HARQ-ACK information feedback processing based on the first configuration information, including at least one of the following:

[0129] The terminal sends the HARQ-ACK information corresponding to the first semi-persistent Scheduling (SPS) PDSCH.

[0130] The terminal does not send the HARQ-ACK information corresponding to the second SPS PDSCH;

[0131] Wherein, the reception time of the first SPS PDSCH is within the valid time of the second object, or the reception time of the first SPS PDSCH does not overlap with the invalid time of the second object; the reception time of the second SPS PDSCH overlaps with the invalid time of the third object, or the reception time of the second SPS PDSCH is not within the valid time of the third object.

[0132] The second object is the cell, carrier, or scenario corresponding to the first SPS PDSCH, and the third object is the cell, carrier, or scenario corresponding to the second SPS PDSCH. At least one of the valid time and invalid time of the second object is determined according to the first configuration information, and at least one of the valid time and invalid time of the third object is determined according to the first configuration information.

[0133] In this embodiment, the reception time of the first SPS PDSCH can be understood as the reception time configured for the first SPS PDSCH. The reception time of the second SPS PDSCH can be understood as the reception time configured for the second SPS PDSCH.

[0134] The reception time of the first SPS PDSCH falls within the valid time of the second object, which can include the entire reception time of the first SPS PDSCH falling within the valid time of the second object. The reception time of the first SPS PDSCH does not overlap with the invalid time of the second object; this can be understood as the intersection of the reception time of the first SPS PDSCH and the invalid time of the second object being an empty set.

[0135] The overlap between the reception time of the second SPS PDSCH and the invalid time of the third object can be understood as at least partially overlapping, for example, partially overlapping and fully overlapping. The reception time of the second SPS PDSCH does not fall within the valid time of the third object; for example, the reception time of the second SPS PDSCH is entirely outside the valid time of the third object, or partly outside the valid time of the third object.

[0136] For example, for a serving cell's previous SPS PDSCH, if the SPS PDSCH is configured on or corresponds to carrier 1, and the configured reception time of the SPS PDSCH overlaps with the effective time of another carrier (carrier), such as carrier 2, or the configured reception time of the SPS PDSCH does not completely fall within the effective time of carrier 1, then the UE determines not to feed back the HARQ-ACK information corresponding to the SPS PDSCH. For example, when constructing the SPS PDSCH HARQ-ACK codebook, the UE only feeds back its HARQ-ACK information for SPS PDSCHs that completely fall within the effective time of the cell / carrier / scenario where the SPS PDSCH is located or corresponds to, or only for SPS PDSCHs that completely or partially overlap with the effective time of the cell / carrier / scenario where the SPS PDSCH is located or corresponds to; or, the UE does not feed back its HARQ-ACK information for SPS PDSCHs that do not completely fall within the effective time of the cell / carrier / scenario where the SPS PDSCH is located or corresponds to, or do not completely or partially overlap with the effective time of the carrier where the SPS PDSCH is located or corresponds to.

[0137] In this embodiment, for the HARQ-ACK information feedback corresponding to the SPS PDSCH, the terminal can feed back the HARQ-ACK information corresponding to the SPS PDSCH (i.e., the first SPS PDSCH) whose configured reception time is within the effective time of its corresponding serving cell, carrier, or scenario; it can choose not to feed back the HARQ-ACK information corresponding to the SPS PDSCH (i.e., the second SPS PDSCH) whose configured reception time overlaps with the ineffective time of its corresponding serving cell, carrier, or scenario. This not only helps to reduce invalid HARQ-ACK information feedback, but also saves the resource overhead of HARQ-ACK information feedback.

[0138] Optionally, in this embodiment, the processing method for SPS PDSCH that falls within the non-valid time of the cell / carrier / scenario corresponding to SPS PDSCH can be the same as the processing method for SPS PDSCH that overlaps with the semi-static UL symbol.

[0139] It should be noted that, for the first SPS PDSCH, in addition to satisfying the condition that the configured reception time is within the effective time of the corresponding serving cell, carrier, or scenario, other conditions may also be satisfied. For example, the first SPS PDSCH may also satisfy at least one of the following: In the SPS PDSCH overlap processing, the SPS PDSCH determined to be the one to be received does not overlap with the UL symbol of the semi-static configuration (such as tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated); and the reception time of the first SPS PDSCH overlaps with the activation time of the cell DTX corresponding to the second object. Optionally, the first SPS PDSCH may also satisfy the conditions required for SPS PDSCHs that feed back HARQ-ACK information in related technologies.

[0140] Optionally, the terminal performs HARQ-ACK information feedback processing based on the first configuration information, including:

[0141] The terminal constructs a HARQ-ACK codebook based on the first configuration information, and the HARQ-ACK codebook includes at least one HARQ-ACK information.

[0142] The terminal sends the HARQ-ACK codebook.

[0143] In this embodiment, a HARQ-ACK codebook can be constructed based on the first configuration information. For example, the HARQ-ACK codebook can be a type 1 HARQ-ACK codebook or a type 3 HARQ-ACK codebook, etc. The aforementioned type 1 HARQ-ACK codebook can also be referred to as a semi-static HARQ-ACK codebook.

[0144] For example, the terminal can determine at least one of the effective time and ineffective time of at least one cell or carrier in which the terminal is configured or activated based on the first configuration information, and can determine the cell or carrier or SPS PDSCH, etc. that needs to feed back HARQ-ACK information based on the effective time and ineffective time of at least one cell or carrier in which the terminal is configured or activated, and then construct the HARQ-ACK codebook based on the determined cell or carrier or SPSPDSCH, etc. that needs to feed back HARQ-ACK information.

[0145] In this embodiment, a HARQ-ACK codebook is constructed and sent according to the first configuration information. This helps to reduce the size of the HARQ-ACK codebook, thereby reducing the resource overhead of HARQ-ACK information feedback.

[0146] Optionally, the terminal constructs a HARQ-ACK codebook based on the first configuration information, including:

[0147] The terminal determines the time unit set corresponding to the timing parameter set K1;

[0148] The terminal determines a set of candidate PDSCH reception opportunities within the time unit set according to the first configuration information. Each candidate PDSCH reception opportunity in the set of candidate PDSCH reception opportunities is located within the effective time of the corresponding cell, carrier, or scenario. Alternatively, each candidate PDSCH reception opportunity in the set of candidate PDSCH reception opportunities is not located within the ineffective time of the corresponding cell, carrier, or scenario. The effective time or ineffective time of the cell, carrier, or scenario is determined according to the first configuration information.

[0149] Optionally, when the UE determines the candidate PDSCH reception timing set, for each row in the TDRA table where the PDSCH reception timing indicated by each row overlaps with the ineffective time of the corresponding cell / carrier / scenario, the UE's processing method can be the same as for each row in the TDRA table where the PDSCH reception timing indicated by each row overlaps with the semi-static configured UL symbol. For example, the row can be excluded, or the row can be excluded from the candidate PDSCH reception timing.

[0150] The terminal constructs a HARQ-ACK codebook based on the candidate PDSCH reception timing set.

[0151] In this embodiment, the aforementioned time unit set may include the time unit corresponding to each k1 value in the timing parameter set K1. For example, if the timing parameter set K1 is {5,6,7}, the aforementioned time unit set may include: the time unit corresponding to k1=5, the time unit corresponding to k1=6, and the time unit corresponding to k1=7. The specific implementation method for determining the time unit set corresponding to the timing parameter set K1 can be found in related technologies, and this embodiment does not limit it in this way.

[0152] For example, the terminal can determine the candidate PDSCH reception timing set in each time unit of the time unit set according to the first configuration information. Each candidate PDSCH reception timing in the candidate PDSCH reception timing set in each time unit is located within the effective time of the cell, carrier, or scenario corresponding to the candidate PDSCH reception timing. The terminal can determine the candidate PDSCH reception timing set in the time unit set based on the candidate PDSCH reception timing sets in all time units of the time unit set. For example, the union of the candidate PDSCH reception timing sets in all time units of the time unit set can be taken as the candidate PDSCH reception timing set in the time unit set.

[0153] It should be noted that, in determining the candidate PDSCH reception timing set within the aforementioned time unit set, in addition to considering the first configuration information, other parameters may also be considered, such as at least one of the following: TDRA table, semi-static TDD uplink / downlink configuration, and uplink / downlink SCS ratio. Optionally, the candidate PDSCH reception timing set within the time unit set can be determined based on the first configuration information and relevant parameters (e.g., at least one of the following: TDRA table, semi-static TDD uplink / downlink configuration, and uplink / downlink SCS ratio) used in related technologies to determine the candidate PDSCH reception timing set.

[0154] In one optional implementation, after determining a first candidate PDSCH reception timing set based on relevant technologies, the terminal can exclude candidate PDSCH reception timings that do not overlap with the corresponding cell, carrier, or scenario from the first candidate PDSCH reception timing set based on first configuration information to obtain a second candidate PDSCH reception timing set, and construct a HARQ-ACK codebook based on the second candidate PDSCH reception timing set.

[0155] The following examples illustrate the construction of the HARQ-ACK codebook:

[0156] When the UE is configured or downlink carrier handover is activated, the UE can construct a semi-static HARQ-ACK codebook based on the following parameters:

[0157] The uplink activation BWP is associated with the time slot timing set K1;

[0158] The set of row indexes for the TDRA table;

[0159] SCS ratio of uplink and downlink BWP;

[0160] TDD uplink / downlink configuration parameters: the tdd-UL-DL-ConfigurationCommon parameter and the tdd-UL-DL-ConfigurationDedicated parameter, which are used to indicate which symbols are uplink and which symbols are downlink;

[0161] Semi-static downlink carrier switching mode (i.e., first configuration information).

[0162] For example, semi-static HARQ-ACK codebook construction may include the following steps:

[0163] Step S21: Based on the timing set K1 associated with the uplink activated BWP, obtain the candidate time slot positions of PDSCH.

[0164] Step S22: Compare the candidate time slot positions of the PDSCH with the TDD uplink and downlink configuration parameters to determine whether the candidate time slot positions of the PDSCH are valid.

[0165] Step S23: Compare the candidate timeslot positions of the PDSCH with the semi-static downlink carrier switching mode to determine whether the candidate timeslot positions of the PDSCH are valid.

[0166] Specifically, for a row in the TDRA table, the validity of a PDSCH candidate reception opportunity is determined based on the semi-static downlink carrier switching mode configuration.

[0167] For example, candidate PDSCH reception opportunities with overlapping uplink symbols configured in the TDRA table and the TDD-UL-DL-ConfigurationCommon parameter and the TDD-UL-DL-ConfigDedicated parameter are excluded. Candidate PDSCH reception opportunities with non-effective time overlap of the carrier corresponding to the serving cell configured in the TDRA table and the semi-static downlink carrier handover mode are also excluded.

[0168] Step S24: Based on the TDRA table associated with the downlink BWP, obtain the rows where time-domain resources do not overlap. For overlapping rows, only one row is considered to obtain the set of candidate PDSCH reception opportunities.

[0169] Step S25: Construct a semi-static HARQ-ACK codebook based on the obtained candidate PDSCH reception timing set.

[0170] Optionally, the HARQ-ACK codebook includes HARQ-ACK information corresponding to at least two carriers.

[0171] Among them, the above-mentioned at least two carriers can correspond to the same cell or different cells.

[0172] Optionally, the HARQ-ACK information corresponding to the at least two carriers is concatenated in ascending order of the carrier index.

[0173] For example, if the above HARQ-ACK codebook includes HARQ-ACK information corresponding to carrier1 and HARQ-ACK information corresponding to carrier2, then in the HARQ-ACK codebook, the HARQ-ACK information can be concatenated in the following order: HARQ-ACK information corresponding to carrier1, HARQ-ACK information corresponding to carrier2.

[0174] Optionally, the HARQ-ACK information corresponding to the at least two carriers can be concatenated in ascending order of the cell index of the corresponding serving cell, and the HARQ-ACK information corresponding to the at least two carriers can correspond to different cells.

[0175] For example, if the above HARQ-ACK codebook includes HARQ-ACK information corresponding to carrier1 and HARQ-ACK information corresponding to carrier2, and carrier1 corresponds to serving cell 0 and carrier2 corresponds to serving cell 1, then in the HARQ-ACK codebook, the HARQ-ACK information can be concatenated in the following order: HARQ-ACK information corresponding to carrier2 (HARQ-ACK information corresponding to serving cell 0), HARQ-ACK information corresponding to carrier1 (HARQ-ACK information corresponding to serving cell 1).

[0176] Optionally, the HARQ-ACK information corresponding to the at least two carriers is concatenated in ascending order of the cell index of the corresponding serving cell, and the HARQ-ACK information of different carriers corresponding to the same serving cell is concatenated in ascending order of the carrier index.

[0177] For example, if the above HARQ-ACK codebook includes HARQ-ACK information corresponding to carrier1, HARQ-ACK information corresponding to carrier2, and HARQ-ACK information corresponding to carrier3, where carrier1 and carrier3 both correspond to serving cell 0, and carrier2 corresponds to serving cell 1, then in the HARQ-ACK codebook, the HARQ-ACK information can be concatenated in the following order: HARQ-ACK information corresponding to carrier1, HARQ-ACK information corresponding to carrier3, and HARQ-ACK information corresponding to carrier2.

[0178] The following examples illustrate the concatenation order of HARQ-ACK information in the HARQ-ACK codebook:

[0179] For type 1 HARQ-ACK codebook:

[0180] Optionally, the carrier1 and carrier2 mentioned above for downlink carrier handover correspond to different serving cell indices. The UE determines the candidate PDSCH reception timing on each serving cell and concatenates the HARQ-ACK information of the candidate PDSCH reception timings on different serving cells according to the ascending order of the serving cell index.

[0181] Optionally, when the downlink carrier handover carrier1 and carrier2 correspond to the same serving cell index, the UE determines the candidate PDSCH reception timing for each carrier and concatenates the HARQ-ACK information corresponding to the candidate PDSCH reception timings on different carriers according to the ascending order of the carrier index. Optionally, if the UE is configured with different serving cells, and a certain serving cell corresponds to more than one carrier, one approach is for the UE to construct the HARQ-ACK codebook according to the ascending order of the serving cell index. For different carriers with the same serving cell index, the codebook is constructed according to the ascending order of the carrier index. Another approach is to concatenate the HARQ-ACK information corresponding to the carrier1 of all serving cells, and then concatenate the HARQ-ACK information corresponding to the carrier2 of all serving cells (if any, concatenation is not required for serving cells without different carriers).

[0182] For example, if serving cell 0 is configured with carrier1 and carrier2 for downlink carrier handover, while serving cell 1 is not configured for downlink carrier handover, then the UE can generate HARQ-ACK codebook information in the following order:

[0183] Method 1: Serving cell 0 carrier1 + Serving cell 0 carrier2 + Serving cell 1;

[0184] Method 2: Serving cell 0 carrier1 + Serving cell 1 + Serving cell 0 carrier2.

[0185] For type 3 HARQ-ACK codebook:

[0186] In the existing type 3 HARQ-ACK codebook construction, the UE concatenates the HARQ-ACK information corresponding to all or specific HARQ processes on different serving cells in ascending order of serving cell index. When carrier1 and carrier2 of downlink carrier handover correspond to the same serving cell index, the UE can concatenate the HARQ-ACK information on different carriers according to the ascending order of the carrier index.

[0187] Optionally, when the downlink carrier handover carrier1 and carrier2 correspond to the same serving cell index, the UE determines the candidate PDSCH reception timing for each carrier and concatenates the HARQ-ACK information corresponding to the candidate PDSCH reception timings on different carriers according to the ascending order of the carrier index. Optionally, if the UE is configured with different serving cells, and a certain serving cell corresponds to more than one carrier, one approach is for the UE to construct the HARQ-ACK codebook according to the ascending order of the serving cell index. For different carriers with the same serving cell index, the HARQ-ACK codebook is constructed according to the ascending order of the carrier index. Another approach is to concatenate the HARQ-ACKs corresponding to carrier1 of all serving cells, and then concatenate the HARQ-ACKs corresponding to carrier2 of all serving cells (if any, concatenation is not required for serving cells not configured with different carriers).

[0188] For example, if serving cell 0 is configured with carrier1 and carrier2 for downlink carrier handover, while serving cell 1 is not configured for downlink carrier handover, then the UE can generate HARQ-ACK codebook information in the following order:

[0189] Method 1: Serving cell 0 carrier1 + Serving cell 0 carrier2 + Serving cell 1;

[0190] Method 2: Serving cell 0 carrier1 + Serving cell 1 + Serving cell 0 carrier2.

[0191] Optionally, the terminal performs HARQ-ACK information feedback processing based on the first configuration information, including:

[0192] When the terminal is configured with a semi-static scheduling HARQ delay, if the feedback time of the first HARQ-ACK information configured to be fed back on the first time unit overlaps with the invalid time of the fourth object, the terminal postpones feeding back part or all of the first HARQ-ACK information.

[0193] The fourth object is the cell, carrier, or scenario where the first physical uplink control channel (PUCCH) is located. The first PUCCH is a PUCCH used to feed back the first HARQ-ACK information. The invalid time of the fourth object is determined according to the first configuration information.

[0194] The aforementioned first time unit can be any time unit. A time unit may include at least one time slot, at least one subframe, or at least one symbol, etc., and this embodiment does not impose any limitations on this.

[0195] For example, the feedback time of the first HARQ-ACK information can be a PUCCH resource used to provide feedback on the first HARQ-ACK information. The PUCCH resource used to provide feedback on the first HARQ-ACK information can be configured by a higher layer, for example, a PUCCH resource configured via the SPS-PUCCH-AN-List parameter or the n1PUCCH-AN parameter.

[0196] For example, when the UE is configured with SPS HARQ delay (such as sps-HARQ-Deferral), if the HARQ-ACK information of the SPS PDSCH fed back in time unit n overlaps with the ineffective time of the serving cell, carrier, or scenario in which the PUCCH is located, the UE can postpone the HARQ-ACK information of the SPS PDSCH to be fed back in a time unit after time unit n.

[0197] In some optional embodiments, when the terminal is configured with semi-static HARQ delay, the HARQ delay feedback condition may include, in addition to the condition that the feedback time of the HARQ-ACK information overlaps with the ineffective time of the cell, carrier, or scenario where the PUCCH used to feed the HARQ-ACK information resides, other conditions may also be included. For example, the PUCCH resource used to feed the HARQ-ACK information overlaps with at least one of the following: a semi-statically configured UL symbol, an SSB symbol, or a Control Resource Set (CORESET) symbol associated with a Type 0 (PDCCH) Common Search Space (CSS set). The terminal may delay feeding back the HARQ-ACK information if any HARQ delay feedback condition is met. For example, the terminal may delay feeding back the HARQ-ACK information if the PUCCH resource used to feed back the HARQ-ACK information overlaps with a semi-statically configured UL symbol, or the terminal may delay feeding back the HARQ-ACK information if the feedback time of the HARQ-ACK information overlaps with the ineffective time of the cell, carrier, or scenario where the PUCCH used to feed back the HARQ-ACK information resides.

[0198] In this embodiment, when the terminal is configured with a semi-static scheduling HARQ delay, if the feedback time of the first HARQ-ACK information configured to be fed back on the first time unit overlaps with the invalid time of the fourth object, the terminal postpones the feedback of part or all of the first HARQ-ACK information. This not only helps to ensure the effectiveness of HARQ-ACK information feedback and reduce HARQ-ACK information feedback failure caused by the overlap between the feedback time of the first HARQ-ACK information and the invalid time of the fourth object, but also increases the chance of HARQ-ACK feedback.

[0199] Optionally, the terminal delays feeding back part or all of the first HARQ-ACK information, including:

[0200] The terminal postpones the feedback of the second HARQ-ACK information to the second time unit.

[0201] Wherein, the second HARQ-ACK information is the HARQ-ACK information in the SPS PDSCH configuration corresponding to the first HARQ-ACK information where the value of the semi-static scheduling HARQ delay is greater than or equal to the first time difference, the second time unit is the earliest time unit after the first time unit used to feed back HARQ-ACK information, and the first time difference is the time difference between the second time unit and the first time unit.

[0202] The following examples illustrate this embodiment:

[0203] When the UE is configured or activated for downlink carrier handover, the UE can perform SPS PDSCHHARQ-ACK deferral in the following manner:

[0204] When the UE is configured with SPS-HARQ-Deferral, if the PUCCH resources used for HARQ-ACK information feedback corresponding to the SPS PDSCH overlap with the invalid time of the cell or carrier where the PUCCH resides, the UE will perform delayed feedback of the HARQ-ACK information corresponding to the SPS PDSCH. Optionally, the invalid time of the aforementioned cell or carrier where the PUCCH resides may include the valid time of SDL and / or the downlink carrier handover time.

[0205] When the UE is configured with SPS-HARQ-Deferral, if within the first time unit (e.g., the first time slot), the UE determines a PUCCH resource configured by a higher layer for feeding back SPS PDSCH HARQ-ACK, for example, feeding back SPS PDSCH HARQ-ACK information (first HARQ-ACK information) on a PUCCH resource configured by the SPS-PUCCH-AN-List parameter or the n1PUCCH-AN parameter, and this PUCCH is not canceled due to overlap with a PUCCH or PUSCH of a higher priority index, and this PUCCH resource is associated with a semi-statically configured UL symbol (such as a UL symbol configured by the tdd-UL-DL-ConfigurationCommon parameter or the tdd-UL-DL-ConfigDedicated parameter), or an SSB symbol (such as one indicated by ssb-PositionsInBurst), or an associated Type0-PDCCH CSS If the CORESET symbol of the set, or the ineffective time of the serving cell or carrier where the PUCCH is located, or the effective time of the SDL or the downlink carrier handover time overlaps, then the UE determines a minimum second time unit (e.g., a second time slot) to feed back the second HARQ-ACK information of the first HARQ-ACK information. The value of sps-HARQ-Deferral configured in the SPS PDSCH configuration corresponding to the second HARQ-ACK information is greater than or equal to the first time difference, which can be the time difference between the first time unit and the second time unit.

[0206] For example, such as Figure 8As shown, the UE determines, based on the downlink carrier handover mode (i.e., the first configuration information), to operate on the pcell (NDL) in slots n-2 and n+5, and on the Scell ​​from slot n to slot n+3. SPS PDSCH1 is configured for transmission on the Pcell (NDL) and is configured with sps-HARQ-Deferral (e.g., sps-HARQ-Deferral value is 10). According to the DCI activation instruction, the UE feeds back its HARQ-ACK in slot n, and in slot n, the UE feeds back the HARQ-ACK information bits of SPS PDSCH1 on the PUCCH resource corresponding to the SPS PDSCH HARQ-ACK, for example, the PUCCH resource configured by the SPS-PUCCH-AN-List parameter or the n1PUCCH-AN parameter. Because the PUCCH resource for feeding back the SPS PDSCH HARQ-ACK overlaps with the non-operating time of the Pcell, the UE cannot transmit the PUCCH in slot n. Because SPS-HARQ-Deferral is configured, the UE will postpone the transmission of the HARQ-ACK information bits, which can be postponed up to slot n-2+10. In slot n+3, the UE is scheduled with a PDSCH2 on the Scell, and according to the instructions of the network-side equipment, the UE will send back the HARQ-ACK information of PDSCH2 in slot n+5. In slot n+5, the UE will multiplex the HARQ-ACK information of SPS PDSCH1 and PDSCH2 onto a single channel for transmission.

[0207] Optionally, the terminal performs HARQ-ACK information feedback processing based on the first configuration information, including:

[0208] When the terminal is configured with semi-static scheduling HARQ delay, if the third HARQ-ACK information configured to be fed back in the third time unit meets the delay feedback condition, the terminal will postpone the fourth HARQ-ACK information to be fed back in the fourth time unit.

[0209] The fourth time unit is located after the third time unit and within the effective time of the fifth object. The fifth object is the cell, carrier, or scenario where the second PUCCH is located. The second PUCCH is a PUCCH used to feed back the fourth HARQ-ACK information. The effective time of the fifth object is determined according to the first configuration information.

[0210] The fourth HARQ-ACK information is the HARQ-ACK information in the SPS PDSCH configuration corresponding to the third HARQ-ACK information where the value of the semi-static scheduling HARQ delay is greater than or equal to the second time difference, where the second time difference is the time difference between the fourth time unit and the third time unit.

[0211] In this embodiment, the third time unit can be any time unit. The delay feedback condition can be a delay feedback condition in related technologies, or it can be a newly defined delay feedback condition. For example, in addition to the delay feedback conditions in related technologies, the delay feedback condition can also include the condition that the feedback time of the HARQ-ACK information overlaps with the ineffective time of the cell, carrier, or scenario where the PUCCH used to feed back the HARQ-ACK information is located.

[0212] For example, the fourth time unit mentioned above may be the earliest time unit for feeding back HARQ-ACK information that is located after the third time unit and within the effective time of the fifth object.

[0213] In this embodiment, if the third HARQ-ACK information configured to be fed back on the third time unit meets the delayed feedback condition, at least a portion of the HARQ-ACK information of the third HARQ-ACK information is postponed to a time unit within the effective time of the fifth object for feedback. This ensures the effectiveness of the delayed feedback of the HARQ-ACK information.

[0214] In summary, the transmission method provided in this application provides a corresponding HARQ-ACK feedback method for downlink carrier switching scenarios. This method can reduce the size of the HARQ-ACK codebook, eliminate invalid HARQ-ACK feedback, or increase the HARQ-ACK feedback opportunity, thereby saving uplink frequency or power resources and improving system efficiency or effectiveness.

[0215] Please see Figure 9 , Figure 9 This is a flowchart of a transmission method provided in an embodiment of this application. This method can be executed by a network-side device, such as... Figure 9 As shown, it includes the following steps:

[0221] Wherein, the reception time of the first SPS PDSCH is within the valid time of the second object, or the reception time of the first SPS PDSCH does not overlap with the invalid time of the second object; the reception time of the second SPS PDSCH overlaps with the invalid time of the third object, or the reception time of the second SPS PDSCH is not within the valid time of the third object.

[0222] The second object is the cell, carrier, or scenario corresponding to the first SPS PDSCH, and the third object is the cell, carrier, or scenario corresponding to the second SPS PDSCH. At least one of the valid time and invalid time of the second object is determined according to the first configuration information, and at least one of the valid time and invalid time of the third object is determined according to the first configuration information.

[0223] It should be noted that whether the network-side device receives the HARQ-ACK information corresponding to the second SPS PDSCH may depend on the implementation of the network-side device. In other words, the network-side device can determine whether to receive the HARQ-ACK information corresponding to the second SPS PDSCH based on its implementation.

[0224] Optionally, the network-side device performs HARQ-ACK information reception processing according to the first configuration information, including:

Each candidate PDSCH reception opportunity in the set of candidate PDSCH reception opportunities is located within the effective time of the corresponding cell, carrier, or scenario. Alternatively, each candidate PDSCH reception opportunity in the set of candidate PDSCH reception opportunities is not located within the ineffective time of the corresponding cell, carrier, or scenario. The effective time or ineffective time of the cell, carrier, or scenario is determined based on the first configuration information.

The first PUCCH is a PUCCH used to feed back the first HARQ-ACK information. The invalid time of the fourth object is determined according to the first configuration information.

[0236] Optionally, the network-side device may delay receiving part or all of the first HARQ-ACK information, including:

[0241] The fourth time unit is located after the third time unit and within the effective time of the fifth object. The fifth object is the cell, carrier, or scenario where the second PUCCH is located. The second PUCCH is a PUCCH used to feed back the fourth HARQ-ACK information. The effective time of the fifth object is determined according to the first configuration information.
