Description

Technical Field

[0002] The SPS HARQ-ACK deferral mechanism can only achieve a relatively semi-static control of the network's SPS HARQ-ACK feedback.

[0088] The following describes the content related to the embodiments of this application.

[0089] I. SPS (Semi-Persistent Scheduling), PDSCH (Physical Downlink Shared Channel), and HARQ-ACK feedback mechanisms in NR (New Radio);

[0090] In NR Rel-15, SPS (Semi-persistent Scheduling) PDSCH transmission was introduced: After activating downlink SPS transmission, periodically initiated PDSCH transmissions (these PDSCH transmissions do not have corresponding downlink control information (DCI) indicators and are transmitted based on a predefined method). For downlink SPS transmissions in NR Rel-15, the network side guarantees that in a certain serving cell group configured for the terminal UE, at most one serving cell has the SPS-Config configuration item configured, and the corresponding SPS PDSCH transmission interval is at least 10 milliseconds. For an SPS PDSCH transmission that ends within time slot n, the UE sends back the corresponding HARQ-ACK within time slot n+k, where k is determined by the PDSCH-to-HARQ-timing-indicator field in the DCI that activated this SPS PDSCH transmission.

[0091] In Rel-16 URLLC (Ultra-Reliable Low-Latency Communication), to minimize the transmission latency of service data, the network side can configure multiple SPS-Config items that are active simultaneously for a single UE (up to 8 items can be configured simultaneously for a portion of the bandwidth BWP of a single serving cell), and the corresponding SPS PDSCH transmission interval can be shortened to a minimum of a single time slot. For a specific SPS-Config item configured for a UE, after activation, the timing relationship between the SPS PDSCH transmission and its corresponding HARQ-ACK feedback is completely consistent with NR Rel-15.

[0092] II. SPS HARQ-ACK conflict and recovery in Time Division Duplex (TDD) systems in URLLC;

[0093] In URLLC Rel-16, downlink SPS transmission has been enhanced, allowing a single UE to support multiple SPS-Configs simultaneously, and each SPS-Config can support smaller periods (down to a single time slot). Since each SPS-Config can only use a single HARQ-ACK feedback timing after activation, indicated by the most recent activation or reactivation DCI, in a TDD system, after activating or reactivating SPS, there may be situations where the physical uplink control channel PUCCH transmission (or the PUCCH resource carrying the SPS HARQ-ACK) corresponding to the HARQ-ACK of some SPS PDSCH Occasions conflicts with at least one semi-static DL / SSB / CORESET#0 symbol (i.e., semi-static downlink symbol, or synchronization signal block symbol, or control resource set 0 symbol), resulting in the SPS HARQ-ACK being dropped. The smaller the SPS transmission period, or the larger the proportion of semi-static DL / SSB / CORESET#0 symbols in the frame structure, the greater the probability of such conflicts, which seriously affects the SPS PDSCH transmission performance (when the network side does not receive the SPS HARQ-ACK, it can only perform blind scheduling for the corresponding SPS PDSCH, thereby reducing system efficiency, or abandoning the corresponding SPS PDSCH, resulting in a large residual packet error rate).

[0094] To address this issue, the SPS HARQ-ACK deferral scheme has been introduced.

[0095] The SPS HARQ-ACK deferral scheme is briefly described below:

[0096] For a given SPS HARQ-ACK bit, if feedback is provided within the uplink UL slot / sub-slot (i.e., time slot or sub-slot) n based on the corresponding SPS PDSCH and HARQ-ACK timing (i.e., HARQ-ACK timing, which is the HARQ-ACK feedback timing relationship, and can be understood as K1 indicated in the corresponding active DCI), then the UL slot / sub-slot n can be called the initial slot / sub-slot corresponding to this SPS HARQ-ACK bit. If this SPS HARQ-ACK bit cannot be multiplexed with other uplink control information UCIs (referring to other UCIs besides SPS HARQ-ACK, including DG (Dynamically Scheduled) HARQ-ACK or Scheduling Request SR or Channel State Information CSI) within the initial slot / sub-slot, and the determined SPS HARQ-ACK PUCCH resource (i.e., the HARQ-ACK PUCCH resource configured by the PUCCH SPS-PUCCH-AN-List-r16 or n1PUCCH-AN parameters, where PUCCH SPS-PUCCH-AN-List-r16 is a list of SPS HARQ-ACK PUCCH resources, n1PUCCH-AN is used to indicate a single SPS HARQ-ACK PUCCH resource, and "AN" represents ACK / NACK) conflicts with the semi-static DL / SSB / CORESET#0 symbol, then when the SPS HARQ-ACK bit corresponding to this SPS HARQ-ACK bit... When deferral is configured in the Config, the deferral operation is triggered, which requires finding the next available PUCCH resource or available PUSCH resource (later in time, currently assumed to be in another slot / sub-slot after the initial slot / sub-slot).

[0097] For one or more SPS HARQ-ACK bits that triggered the deferral operation (each SPS HARQ-ACK bit may correspond to a different initial slot / sub-slot; in the following text, these SPS HARQ-ACK bits may also be considered to be in the deferral process), search for available PUCCH resources or available PUSCH resources in each slot / sub-slot after the initial slot / sub-slot. If, within a candidate slot / sub-slot, the SPS HARQ-ACK bits (including those in the deferral process) can be multiplexed with other UCIs (i.e., other UCIs besides SPS HARQ-ACK, including DG HARQ-ACK, SR, or CSI), or (when they cannot be multiplexed with other UCIs) the determined SPS HARQ-ACK PUCCH resource (i.e., the HARQ-ACK PUCCH resource configured by the PUCCH SPS-PUCCH-AN-List-r16 or n1PUCCH-AN parameters) does not conflict with the semi-static DL / SSB / CORESET#0 symbol, then a usable PUCCH resource or usable PUSCH resource has been found for (all) SPS HARQ-ACK bits in the deferral process within this candidate slot / sub-slot. At this point, deferral is stopped, and this candidate slot / sub-slot is also considered a deferred slot for these bits in the deferral process. The SPSHARQ-ACK bits correspond to the target slot / sub-slot.

[0098] Each SPS Config can be configured independently to enable or disable deferral, and when deferral is configured, the maximum deferral value can be further configured. For a given SPS HARQ-ACK bit, if it triggers a deferral operation, and no available PUCCH or PUSCH resource is found in a Candidate slot / sub-slot that is a distance of the maximum deferral value from the initial slot / sub-slot, then this SPS HARQ-ACK bit will be discarded due to timeout.

[0099] III. HARQ-ACK retransmission mechanism in URLLC;

[0100] In URLLC Rel-17, for deleted HARQ-ACKs (such as low-priority HARQ-ACKs dropped due to Rel-16 intra-UE prioritization, or HARQ-ACKs deleted due to Rel-16 cancellation indication), two retransmission mechanisms have been introduced: Enhanced Type-3 HARQ-ACK codebook and One-shot triggering of HARQ-ACK re-transmission.

[0101] 1. Regarding the Enhanced Type-3 HARQ-ACK codebook:

[0102] The main idea behind the Enhanced Type-3 HARQ-ACK codebook is to follow the construction approach of the Rel-16 Type-3 codebook (constructing the codebook from the perspective of the HARQ process, using a cyclic structure of CC (carrier or cell) – HARQ process – TB (transport block) to determine the HARQ-ACK bit sequence corresponding to the codebook; considering all downlink HARQ processes configured for each cell in all cells configured for the UE). However, it can report only the HARQ-ACK corresponding to a subset of the CC or HARQ process. This allows for triggering the reporting of HARQ-ACK corresponding to a specific subset as needed, thus using a smaller codebook size to match the required retransmitted HARQ-ACK information. Considering that the required subset varies under different circumstances, the network can pre-configure a codebook or state list. Each codebook or state in the list corresponds to a (different) subset (corresponding to a single Enhanced Type-3 HARQ-ACK codebook). The network can select the best-matching subset as needed and trigger the corresponding codebook or state. Currently, the maximum number of Enhanced Type-3 HARQ-ACK codebooks that UE can support simultaneously is 8.

[0103] 2. Regarding One-shot triggering of HARQ-ACK re-transmission:

[0104] The main idea behind one-shot triggering of HARQ-ACK re-transmission is to trigger the retransmission of a deleted HARQ-ACK codebook within a specific UL slot / sub-slot. The triggering DCI instructs a new PUCCH resource within the UL slot / sub-slot to retransmit the deleted HARQ-ACK codebook intact. Each DCI can only trigger the retransmission of a single HARQ-ACK codebook. Only a single HARQ-ACK codebook can be retransmitted within a single new UL slot / sub-slot. If an initial HARQ-ACK transmission (with the same physical layer priority) still exists in the new UL slot / sub-slot, the retransmitted HARQ-ACK codebook is concatenated after the HARQ-ACK codebook corresponding to the initial transmission.

[0105] The information 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.

[0106] This application provides an information transmission method that can be applied to a terminal, such as... Figure 2 As shown, it includes:

[0107] Step 21: The terminal receives the one-time trigger downlink control information (DCI) sent by the network-side device;

[0108] Step 22: The terminal determines the feedback codebook of the first semi-persistent scheduling hybrid automatic repeat request response (SPS HARQ-ACK) based on the one-time trigger DCI; and sends the feedback codebook to the network-side device within the first time unit; wherein, the first SPS HARQ-ACK includes the second SPS HARQ-ACK existing in the second time unit; the first time unit is the same as the second time unit, or the first time unit is located after the second time unit.

[0109] The first time unit can be understood as the feedback time unit, and the second time unit can be understood as the trigger time unit. "The first time unit and the second time unit are the same" includes at least the following situations: the time units are the same, but the positions they occupy are offset; for example: the time units are the same, but the symbols they occupy are offset.

[0110] The step of determining the feedback codebook of the first semi-persistent scheduling hybrid automatic repeat request response (SPSHARQ-ACK) based on the one-time trigger DCI includes: the terminal determining the information of the second time unit based on the one-time trigger DCI; the terminal determining the first SPS HARQ-ACK based on the information of the second time unit; and the terminal constructing the feedback codebook based on the first SPS HARQ-ACK.

[0116] Specifically, the delayed SPS HARQ-ACK can correspond to one or more time units (earlier than the first time unit).

[0117] Furthermore, the first SPS HARQ-ACK also includes at least one of the following: an SPS HARQ-ACK that needs to be transmitted from the next time unit after the second time unit until the first time unit; and an initial transmission of HARQ-ACK within the first time unit.

[0123] The first time unit can be understood as the feedback time unit, and the second time unit can be understood as the trigger time unit. "The first time unit and the second time unit are the same" includes at least the following situations: the time units are the same, but the positions they occupy are offset; for example: the time units are the same, but the symbols they occupy are offset.

[0129] The second SPS HARQ-ACK includes at least one of the following: initial SPS HARQ-ACK; delayed SPSHARQ-ACK; wherein the initial SPS HARQ-ACK refers to the SPS HARQ-ACK fed back within the second time unit based on the corresponding semi-persistent scheduling physical downlink shared channel SPSPDSCH and the HARQ-ACK feedback timing relationship; the delayed SPS HARQ-ACK refers to the SPSHARQ-ACK that has already triggered or started the delay process within a time unit earlier than the second time unit.

[0133] In this embodiment, a one-time trigger downlink control information (DCI) is sent to the terminal via a network-side device. The network-side device determines reference information for receiving the feedback codebook of the first semi-persistent scheduling hybrid automatic repeat request response (SPS HARQ-ACK), and receives the feedback codebook from the terminal based on the one-time trigger DCI within a first time unit according to the reference information. The first SPS HARQ-ACK includes a second SPS HARQ-ACK existing in a second time unit. The first time unit is the same as the second time unit, or the first time unit is located after the second time unit. This allows for more flexible and dynamic control of the SPS HARQ-ACK feedback and improves the reliability of the SPS HARQ-ACK feedback, thereby ensuring the performance of SPS PDSCH transmission.

[0134] It should be noted here that the one-shot triggering DCI in the embodiments of this application specifically refers to the DCI used for one-shot triggering of re-transmission.

[0135] This application also provides an information transmission method, such as... Figure 10 As shown, it includes:

[0136] Step 101: The terminal receives a one-time trigger downlink control information (DCI) sent by the network-side device in the first case; the first case includes: at least one valid HARQ-ACK bit in the first HARQ-ACK codebook satisfies the first condition;

[0137] Step 102: The terminal retransmits the first HARQ-ACK codebook to the network-side device according to the one-time triggered DCI; wherein the first HARQ-ACK codebook is constructed within the third time unit; the first condition includes at least one of the following: the valid HARQ-ACK is not an SPS HARQ-ACK bit; the valid HARQ-ACK is an SPS HARQ-ACK bit, but the corresponding SPS configuration item has not configured a delay; the valid HARQ-ACK is an SPS HARQ-ACK bit, the corresponding SPS configuration item has configured a delay, but the valid HARQ-ACK has not been delayed; the valid HARQ-ACK is an SPS HARQ-ACK bit, the corresponding SPS configuration item has configured a delay, and the valid HARQ-ACK has triggered a delay, and the third time unit is determined as the target time unit.

[0138] The method of retransmitting the first HARQ-ACK codebook to the network-side device according to the one-time trigger DCI includes: in a second case, the terminal multiplexes the first HARQ-ACK codebook with at least one delayed SPS HARQ-ACK bit to obtain a final feedback codebook; the second case includes: within the feedback time unit corresponding to the first HARQ-ACK codebook, the at least one delayed SPS HARQ-ACK bit satisfies a second condition; the terminal sends the final feedback codebook to the network-side device according to the one-time trigger DCI; wherein the second condition includes any one of the following: the delayed SPS HARQ-ACK bit corresponds to a second priority; the second priority is the priority indicated by the one-time trigger DCI or a predefined priority; the delayed SPS HARQ-ACK bit corresponds to any priority; the priority corresponding to the delayed SPS HARQ-ACK bit is higher than or equal to the second priority.

[0139] In this scheme, it is also possible that the terminal transmits the first HARQ-ACK codebook triggered by transmission, while the at least one delayed SPS HARQ-ACK bit continues to perform the delayed operation.

[0140] In this embodiment, a terminal receives a one-time triggered downlink control information (DCI) sent by a network-side device under a first condition. The first condition includes: at least one valid HARQ-ACK bit in the first HARQ-ACK codebook satisfies a first condition. The terminal retransmits the first HARQ-ACK codebook to the network-side device according to the one-time triggered DCI. The first HARQ-ACK codebook is constructed within a third time unit. The first condition includes at least one of the following: the valid HARQ-ACK is not an SPS HARQ-ACK bit; the valid HARQ-ACK is an SPS HARQ-ACK bit, but the corresponding SPS configuration item has not configured a delay; the valid HARQ-ACK is an SPS HARQ-ACK bit, the corresponding SPS configuration item has configured a delay, but the valid HARQ-ACK has not been delayed; the valid HARQ-ACK is an SPSHARQ-ACK bit, the corresponding SPS configuration item has configured a delay, and the valid HARQ-ACK has triggered a delay, and the third time unit is determined as the target time unit. This allows for more flexible and dynamic control of SPS. The feedback of HARQ-ACK is improved, and the reliability of SPS HARQ-ACK feedback is enhanced to ensure the performance of SPS PDSCH transmission.

[0141] This application also provides an information transmission method, such as... Figure 11 As shown, it includes:

[0142] Step 111: In the first case, the network-side device sends a one-time trigger downlink control information (DCI) to the terminal; the first case includes: at least one valid HARQ-ACK bit in the first HARQ-ACK codebook satisfies the first condition;

[0143] Step 112: The network-side device receives the first HARQ-ACK codebook from the terminal based on the one-time DCI retransmission; wherein the first HARQ-ACK codebook is constructed within a third time unit; the first condition includes at least one of the following: the valid HARQ-ACK is not an SPS HARQ-ACK bit; the valid HARQ-ACK is an SPS HARQ-ACK bit, but the corresponding SPS configuration item has not configured a delay; the valid HARQ-ACK is an SPS HARQ-ACK bit, the corresponding SPS configuration item has configured a delay, but the valid HARQ-ACK has not been delayed; the valid HARQ-ACK is an SPS HARQ-ACK bit, the corresponding SPS configuration item has configured a delay, and the valid HARQ-ACK has triggered a delay, and the third time unit is determined as the target time unit.

[0144] Furthermore, the information transmission method further includes: the network-side device determining that the terminal, in a second situation, performs HARQ-ACK multiplexing of the first HARQ-ACK codebook with at least one delayed SPS HARQ-ACK bit to obtain a final feedback codebook; the second situation includes: at least one delayed SPS HARQ-ACK bit satisfies a second condition within the feedback time unit corresponding to the first HARQ-ACK codebook; the network-side device receiving the first HARQ-ACK codebook retransmitted by the terminal according to a one-time triggered DCI includes: the network-side device receiving the final feedback codebook sent by the terminal according to a one-time triggered DCI; wherein, the second condition includes any one of the following: the delayed SPS HARQ-ACK bit corresponds to a second priority; the second priority is the priority indicated by the one-time triggered DCI or a predefined priority; the delayed SPS HARQ-ACK bit corresponds to any priority; the priority corresponding to the delayed SPS HARQ-ACK bit is higher than or equal to the second priority.

[0145] In this scheme, it is also possible that the terminal transmits the first HARQ-ACK codebook triggered by transmission, while the at least one delayed SPS HARQ-ACK bit continues to perform the delayed operation.

[0146] In this embodiment, the network-side device sends a one-time triggered downlink control information (DCI) to the terminal in a first scenario. The first scenario includes: at least one valid HARQ-ACK bit in the first HARQ-ACK codebook satisfies a first condition. The network-side device receives the first HARQ-ACK codebook retransmitted by the terminal according to the one-time triggered DCI. The first HARQ-ACK codebook is constructed within a third time unit. The first condition includes at least one of the following: the valid HARQ-ACK is not an SPS HARQ-ACK bit; the valid HARQ-ACK is an SPS HARQ-ACK bit, but the corresponding SPS configuration item has not configured a delay; the valid HARQ-ACK is an SPS HARQ-ACK bit, the corresponding SPS configuration item has configured a delay, but the valid HARQ-ACK has not been delayed; the valid HARQ-ACK is an SPSHARQ-ACK bit, the corresponding SPS configuration item has configured a delay, and the valid HARQ-ACK has triggered a delay, and the third time unit is determined as the target time unit. This allows for more flexible and dynamic control of SPS. The feedback of HARQ-ACK is improved, and the reliability of SPS HARQ-ACK feedback is enhanced to ensure the performance of SPS PDSCH transmission.

[0147] The following is an example of the information transmission method provided in the embodiments of this application, with the time unit being Slot / sub-slot as an example.

[0148] To address the aforementioned technical issues, and considering that by actively triggering SPS HARQ-ACK feedback based on one-shot triggering of re-transmission, the network side can more flexibly and dynamically control SPS HARQ-ACK feedback and improve its reliability, thereby ensuring the performance of SPS PDSCH transmission; however, no solution is currently provided for the combination or interoperability of one-shot triggering of re-transmission and SPS HARQ-ACK deferral, making it impossible to effectively combine the two to achieve flexible, controllable, and timely reliable SPS HARQ-ACK feedback; therefore, this application provides an information transmission method, mainly involving: triggering SPS HARQ-ACK bits (corresponding to the second SPS HARQ-ACK bit) within a specified Slot / sub-slot (hereinafter referred to as the triggering Slot / sub-slot, corresponding to the aforementioned second time unit) based on one-shot triggering of re-transmission. HARQ-ACK is triggered within the indicated slot / sub-slot (hereinafter referred to as the feedback slot / sub-slot, corresponding to the first time unit mentioned above). The downlink assignment (DL assignment) DCI used to trigger HARQ-ACK feedback is referred to as One-shot triggering DCI below. Specifically, the target or operation object of One-shot triggering DCI is the (Deferred) SPS HARQ-ACK bit; the operation of triggering retransmissions of other codebooks and piggybacking the transmission of the Deferred SPS HARQ-ACK bit is described in Example 1 below.

[0149] Specifically, the solution provided in this application embodiment may include at least one of the following operations:

[0150] Operation 1: Trigger the determination of Slot / sub-slot;

[0151] Currently, the primary consideration is to trigger a slot / sub-slot that is either the feedback slot / sub-slot or a slot / sub-slot preceding the feedback slot / sub-slot. Optionally, a slot / sub-slot can also be triggered after the feedback slot / sub-slot; this is not a restriction.

[0152] When determining which slot / sub-slot to trigger, any of the following methods can be used:

[0153] Method 1: Trigger the Slot / sub-slot to a predefined Slot / sub-slot (corresponding to the predefined time unit mentioned above);

[0154] In this case, One-shot triggering DCI does not require explicit indication of slot / sub-slot triggering. One-shot triggering DCI can schedule PDSCH or not schedule PDSCH (for example, setting the Frequency Domain Resource Allocation (FDRA) indication field to a special value to indicate that PDSCH is not scheduled).

[0155] The following methods may be further employed:

[0156] Method 1-1: Trigger Slot / sub-slot as feedback Slot / sub-slot;

[0157] The purpose or application scenario is as follows: When there is no dynamically scheduled DG HARQ-ACK (i.e., HARQ-ACK corresponding to DCI) in the feedback Slot / sub-slot, the PUCCH resources used in the feedback Slot / sub-slot can be dynamically adjusted (before adjustment, only semi-static configured SPS HARQ-ACK PUCCH resources, SR PUCCH resources, or CSI PUCCH resources can be used, which may be dropped because they are multiplexed with SR or CSI but cannot actually be transmitted, or because the SPS HARQ-ACK PUCCH resources conflict with invalid symbols (illegal symbols, i.e., the aforementioned semi-static DL / SSB / CORESET#0 symbols), further delaying deferral, or being dropped because the upper limit corresponding to the maximum deferral value is reached), so as to ensure the timely and reliable transmission of (Deferred) SPS HARQ-ACK.

[0158] Method 1-2: Triggering Slot / sub-slot is One-shot triggering the Slot / sub-slot where the DCI receiver is located;

[0159] The purpose or application scenario may be to trigger feedback to specify the SPS HARQ-ACK bits present in the Slot / sub-slot, or further include SPS HARQ-ACK bits associated with these SPS HARQ-ACK bits (see “HARQ-ACK item 2” below) to avoid being dropped or further deferred, thereby ensuring the timely and reliable transmission of SPS HARQ-ACK.

[0160] The slot / sub-slot where the One-shot triggering DCI is received can be understood as: the UL slot / sub-slot where the physical downlink control channel (PDCCH) carrying the One-shot triggering DCI ends, or the last UL slot / sub-slot among the UL slots / sub-slots that overlap with the PDCCH carrying the One-shot triggering DCI.

[0161] Methods 1-3: Triggering a slot / sub-slot is a slot / sub-slot offset by M slots / sub-slots relative to the reference slot / sub-slot (corresponding to the reference time unit mentioned above);

[0162] Purpose or application scenario: Same as method 1-2.

[0163] The reference slot / sub-slot can be: feedback slot / sub-slot, or the slot / sub-slot where the one-shot triggering DCI receiver is located.

[0164] When the reference slot / sub-slot is a feedback slot / sub-slot, M can be understood as the number of slots / sub-slots offset in the past time direction (i.e., to the left on the time axis). This means the triggering slot / sub-slot is a feedback slot / sub-slot (in which case M can be considered 0), or a slot / sub-slot that precedes the feedback slot / sub-slot and is offset by M slots / sub-slots. When the reference slot / sub-slot is the slot / sub-slot where the One-shot triggering DCI reception is located, M can be understood as the number of slots / sub-slots offset in the past time direction (i.e., to the left on the time axis) or in the future time direction (i.e., to the right on the time axis). It can be further specified that the offset in a certain direction is positive, and the offset in the opposite direction is negative. M can be an integer, and based on the aforementioned direction specification, it can be 0, a positive integer, or a negative integer. M can be determined based on predefined rules or configured by higher-layer signaling.

[0165] For example, when the reference slot / sub-slot is the slot / sub-slot where the One-shot triggering DCI reception is located, M can be understood as the slot / sub-slot offset relative to the end time of the One-shot triggering DCI, which is the first (or earliest) UL slot / sub-slot (assuming it is the intended time unit) that meets the DCI decoding delay requirement, relative to the slot / sub-slot where the One-shot triggering DCI reception is located (assuming it is the reference time unit). That is, M is the time unit offset of the intended time unit relative to the reference time unit. Here, the first time corresponding to the UL slot / sub-slot is the start time of this UL slot / sub-slot, or the start time of the PUCCH resources expected to be used within this UL slot / sub-slot. Then, the triggering slot / sub-slot can be understood as the first (or earliest) UL slot / sub-slot that meets the DCI decoding delay requirement.

[0166] Method 2: Triggering Slot / sub-slot is a one-shot triggering DCI-indicated Slot / sub-slot;

[0167] The purpose or application scenario can be: basically the same as the methods 1-1 to 1-3 above. The main difference is that the slot / sub-slot can be triggered by one-shot triggering DCI dynamic indication, which is more flexible, but requires the introduction of additional indication overhead.

[0168] At this point, One-shot triggering DCI needs to explicitly indicate the triggering of Slot / sub-slot:

[0169] (1) When it is necessary to keep the DCI size (size, which can be understood as the corresponding number of bits) unchanged, the One-shot triggering DCI cannot schedule PDSCH. In this case, some unused indicator fields in the One-shot triggering DCI (such as the indicator fields used when scheduling PDSCH) can be used to indicate the triggering of Slot / sub-slot.

[0170] (2) When a new indicator bit can be introduced into the One-shot triggering DCI, it does not restrict whether the One-shot triggering DCI schedules PDSCH (for example, it determines whether PDSCH is actually scheduled based on the value of the FDRA indicator field). In this case, a new indicator field is introduced to indicate the triggering slot / sub-slot.

[0171] When indicating the triggering of a slot / sub-slot, you can indicate either the absolute time position of the triggering slot / sub-slot, such as the SFN (System Frame Number) and the slot / sub-slot index within the radio frame, or the offset N relative to the reference slot / sub-slot.

[0172] The reference slot / sub-slot can be: feedback slot / sub-slot, or the slot / sub-slot where the one-shot triggering DCI receiver is located.

[0173] When the reference slot / sub-slot is a feedback slot / sub-slot, N can be understood as the number of slots / sub-slots offset in the past time direction (i.e., to the left on the time axis). When the reference slot / sub-slot is the slot / sub-slot where the One-shot triggering DCI reception is located, N can be understood as the number of slots / sub-slots offset in the past time direction (i.e., to the left on the time axis) or in the future time direction (i.e., to the right on the time axis). It can be further specified that the offset in a certain direction is positive, and the offset in the opposite direction is negative. N can be an integer, and based on the aforementioned direction specification, it can be 0, a positive integer, or a negative integer. N can be determined based on predefined rules or configured by higher-layer signaling.

[0174] When applying any of the above methods, it is assumed that an SPS HARQ-ACK bit (including the initial SPS HARQ-ACK and / or the deferred SPS HARQ-ACK) must exist within the triggering slot / sub-slot, and that the triggered SPS HARQ-ACK bit is considered to have already had a transmission opportunity and does not need to be triggered again or defered further. Alternatively, the UE does not expect that no SPS HARQ-ACK bit will be absent from the triggering slot / sub-slot; after receiving the One-shot triggering DCI, the UE does not need to defer the SPS HARQ-ACK bit corresponding to (or triggered by) the One-shot triggering DCI after the feedback slot / sub-slot (the UE can drop this information and does not need to maintain it).

[0175] Operation 2: Trigger the determination of SPS HARQ-ACK and the construction of the codebook;

[0176] Within the feedback slot / sub-slot, when triggering the organization's HARQ-ACK codebook based on One-shot triggering of re-transmission, the organization's codebook includes at least one of the following (or at least HARQ-ACK item 1, optionally including one or more other items):

[0177] HARQ-ACK item 1: Triggers the SPS HARQ-ACK bit present in the slot / sub-slot, and may include at least one of the following:

[0178] HARQ-ACK Sub-item 1-1: All Initial SPS HARQ-ACKs;

[0179] The Initial SPS HARQ-ACK here refers to the SPS HARQ-ACK fed back within the trigger slot / sub-slot based on the corresponding SPS PDSCH and HARQ-ACK timing (i.e., K1 indicated in the activation DCI, corresponding to the above HARQ-ACK feedback timing relationship). The SPS Config corresponding to a certain bit may or may not be configured with deferral.

[0180] Optionally, when the triggering slot / sub-slot is not a feedback slot / sub-slot, one or more of the following can be removed from the Initial SPSHARQ-ACK, and only the transmission of the remaining Initial SPS HARQ-ACK (if present) will be considered:

[0181] (1) The corresponding SPS Config does not have deferral Initial SPS HARQ-ACK configured (assuming that the reliability requirements for these SPSHARQ-ACKs are low);

[0182] (2) The corresponding SPS Config is configured with deferral, but the feedback Slot / sub-slot has exceeded the maximum deferral value of the corresponding SPS Config relative to the triggering Slot / sub-slot (as the Initial slot / sub-slot) of the Initial SPS HARQ-ACK (assuming that these SPS HARQ-ACKs have timed out and are of little use).

[0183] (3) The corresponding SPS Config is configured with deferral, but the Initial SPS HARQ-ACK of the corresponding Target slot / sub-slot has been determined before the feedback of Slot / sub-slot (assuming that these SPS HARQ-ACKs have already obtained the opportunity to be transmitted).

[0184] HARQ-ACK sub-items 1-2: All Deferred SPS HARQ-ACK;

[0185] The Deferred SPS HARQ-ACK here refers to the SPS HARQ-ACK that has been triggered or started (in the Slot / sub-slot that triggered the Slot / sub-slot), and any bit in it must correspond to an SPS Config that has been configured to deferral.

[0186] Optionally, when the triggering slot / sub-slot is not a feedback slot / sub-slot, the following Deferred SPS HARQ-ACK in the Deferred SPSHARQ-ACK can be removed, and only the transmission of the remaining Deferred SPS HARQ-ACK (if it exists) will be considered:

[0187] (1) Feedback Slot / sub-slot has exceeded the maximum deferral value of the corresponding SPS Config relative to the corresponding Initial slot / sub-slot (assuming that these SPSHARQ-ACKs have timed out and are of little use);

[0188] (2) The DeferredSPS HARQ-ACK corresponding to the Target slot / sub-slot has been determined before the feedback Slot / sub-slot (assuming that these SPS HARQ-ACKs have already obtained the opportunity to be transmitted).

[0189] HARQ-ACK item 2: From the next Slot / sub-slot that triggers the Slot / sub-slot until the Slot / sub-slot is fed back, the SPS HARQ-ACK that needs to be transmitted;

[0190] The SPS HARQ-ACK to be transmitted here can include the SPS HARQ-ACK bits present in each Slot / sub-slot (assuming it is a reference Slot / sub-slot) from the triggering Slot / sub-slot to the feedback Slot / sub-slot. The determination of the SPS HARQ-ACK bits present in the reference Slot / sub-slot can be found in the corresponding description in "HARQ-ACK Sub-item 1-1", i.e., all InitialSPS HARQ-ACKs corresponding to the reference Slot / sub-slot, simply replacing "triggering Slot / sub-slot" with "reference Slot / sub-slot" in the description. Note that it is currently assumed that the organization's codebook already includes "HARQ-ACK item 1", therefore, for the reference Slot / sub-slot, there is no need to consider the Deferred SPS HARQ-ACK (to avoid duplication), only the newly generated Initial SPS HARQ-ACK needs to be considered.

[0191] The “SPS HARQ-ACK that needs to be transmitted” mentioned here is only considered when the triggering slot / sub-slot is not a feedback slot / sub-slot.

[0192] Optionally, only the SPS HARQ-ACK bits existing in L-1 slots starting from the next slot / sub-slot after the triggering slot / sub-slot can be considered. That is, if it is assumed that the organization's codebook already includes "HARQ-ACK item 1", then the SPS HARQ-ACK bits existing in a total of L slots / sub-slots starting from the triggering slot / sub-slot are considered (if there are still less than L slots from the triggering slot / sub-slot until the feedback slots are less than L, the actual number shall prevail). L is determined based on predefined rules or configured by higher-layer signaling.

[0193] Optionally, for the aforementioned number of slots / sub-slots (L-1 slots, or all slots up to the feedback slot / sub-slot) starting from the next slot / sub-slot after the triggering slot / sub-slot, only the SPS HARQ-ACK bits corresponding to the reference SPS Config and / or reference priority within each slot / sub-slot are considered. Here, the reference SPS Config (or reference priority) is any SPS Config (or physical layer priority) corresponding to the SPS HARQ-ACK bits within the triggering slot / sub-slot. For example, assuming that the SPS HARQ-ACK bits within the triggering slot / sub-slot correspond to two SPS Configs, then for these "number of slots / sub-slots", only the SPS HARQ-ACK bits corresponding to any one of these two SPS Configs within each slot / sub-slot are considered.

[0194] HARQ-ACK item 3: Feedback on the initial transmission HARQ-ACK within the slot / sub-slot, which may include at least one of the following:

[0195] HARQ-ACK Sub-item 3-1: When One-shot triggering DCI schedules PDSCH, the HARQ-ACK corresponding to the scheduled PDSCH;

[0196] HARQ-ACK Sub-item 3-2: Feedback on the Initial SPS HARQ-ACK corresponding to the Slot / sub-slot;

[0197] When the trigger slot / sub-slot is a feedback slot / sub-slot, the Initial SPS HARQ-ACK here is the Initial SPS HARQ-ACK corresponding to "HARQ-ACK sub-item 1-1".

[0198] HARQ-ACK Sub-item 3-3: Other DCI indications of HARQ-ACK feedback within the feedback slot / sub-slot;

[0199] Other DCIs include any DCI that requires feedback of the corresponding HARQ-ACK, such as downlink scheduling DCIs, DCIs that indicate SPS release, etc.

[0200] When organizing the codebook, the initial transmission HARQ-ACK (if it exists; corresponding to "HARQ-ACK item 3") can be constructed into a separate HARQ-ACK sub-codebook based on the Rel-16 rules (assumed to be the first sub-codebook). The Deferred SPS HARQ-ACK and / or the Initial SPS HARQ-ACK that does not correspond to the feedback Slot / sub-slot (if it exists; corresponding to "HARQ-ACK item 2" and / or "HARQ-ACK item 3"; excluding the Initial SPS HARQ-ACK that does not correspond to the feedback Slot / sub-slot) can be constructed into a separate HARQ-ACK sub-codebook based on the Rel-16 rules (assumed to be the second sub-codebook; it can be uniformly treated as the Deferred SPS HARQ-ACK in the SPS HARQ-ACK deferral to construct the HARQ-ACK (sub)codebook). When both subcodebooks exist, the first and second subcodebooks can be concatenated to obtain the actual HARQ-ACK codebook for transmission. For example, the second subcodebook can be concatenated after the first subcodebook.

[0201] Step 3: Feedback on the determination of PUCCH resources;

[0202] When there are A One-shot triggering DCIs (A>0; if there are more than one, based on the current agreement, they are required to indicate the same HARQ-ACK codebook, or extended to indicate the same HARQ-ACK reporting range), and B other DCIs (which need to provide corresponding HARQ-ACK feedback; B≥0) indicate the same feedback Slot / sub-slot, the determination of the PRI (PUCCH Resource Indicator) corresponding to the PUCCH resources used within the feedback Slot / sub-slot can be done in any of the following ways:

[0203] Method 1: Always use the PRI indicated by the last DCI among all DCIs;

[0204] All DCIs here refer to the A+B DCIs mentioned above. The order of the DCIs can be sorted using the current rules. For example, they can be sorted based on the start time of the PDCCH monitoring occupancy that detected the DCI; DCIs with later start times in the corresponding PDCCH monitoring occupancy are considered received later. When multiple DCIs are received within the same start time across multiple PDCCH monitoring occupancy periods, the order of these DCIs can be further determined based on the cell index; for example, the DCI with a larger corresponding cell index is considered received later.

[0205] Method 2: Always use the PRI indicated by the (last) One-shot triggering DCI;

[0206] Generally, the PRI indicated by the last One-shot triggering DCI can be used. Optionally, it is required that the PRI indicated in A One-shot triggering DCIs be consistent; in this case, the PRI indicated by any One-shot triggering DCI can be used.

[0207] Method 3: Requires all DCI-indicated PRI to be consistent.

[0208] At this point, you can use the PRI indicated in any of the DCIs.

[0209] Operation 4: Physical layer priority handling;

[0210] Generally, the above operations can be understood as follows: One-shot triggering the physical layer priority indicated by the DCI, simultaneously indicating the feedback priority (i.e., the physical layer priority of the HARQ-ACK codebook transmitted in the feedback slot / sub-slot, or the physical layer priority corresponding to the PUCCH carrying this HARQ-ACK codebook), and the trigger priority, i.e., the physical layer priority corresponding to the SPS HARQ-ACK bit that triggers the transmission (i.e., only the SPS HARQ-ACK bit corresponding to the physical layer priority indicated in the DCI is triggered; this is the current situation). The physical layer priority corresponding to a particular SPS HARQ-ACK can be determined by its corresponding SPS Config (specifically, the higher-level configuration parameters of the SPS Config may include the physical layer priority).

[0211] Optionally, the above operations can also be extended to SPS HARQ-ACK triggering scenarios that cross physical layer priorities (i.e., the trigger priority is not required to be the same as the feedback priority, or in other words, the physical layer priority corresponding to the SPS HARQ-ACK bit that triggers the transmission is not required to be the same as the physical layer priority indicated by the One-shot triggering DCI).

[0212] Specifically, assuming that based on the indication in the One-shot triggering DCI, or predefined rules (e.g., specifying a default physical layer priority, such as low priority, when there is no explicit indication in the DCI), the feedback priority (i.e., the physical layer priority of the HARQ-ACK codebook transmitted in the feedback slot / sub-slot, or the physical layer priority of the PUCCH carrying this HARQ-ACK codebook) can be determined, the first SPS HARQ-ACK in the aforementioned scheme can be determined using any of the following priority constraint schemes (i.e., the following schemes correspond to the above priority constraint conditions):

[0213] Option 1: The SPS HARQ-ACK in the above operations must correspond to the feedback priority (i.e., it must correspond to the first priority mentioned above);

[0214] For example, in "Operation 2: Determining the trigger of SPS HARQ-ACK and constructing the codebook", only SPS HARQ-ACK with the corresponding feedback priority is considered.

[0215] Option 2: The SPS HARQ-ACK in the above operations can correspond to any priority;

[0216] The phrase "corresponding to any priority" mentioned here can be understood as not paying attention to the physical layer priority of SPS HARQ-ACK, and processing it uniformly, such as including both high-priority and low-priority SPS HARQ-ACKs in the processing scope.

[0217] At this point, you can directly use the above operations.

[0218] Optionally, considering that it is generally believed that when high-priority HARQ-ACK and low-priority HARQ-ACK are multiplexed in the same PUCCH, they should be encoded separately, the following adjustment can be introduced: In "Operation 2: Determination of SPS HARQ-ACK and Construction of Codebook", when organizing the codebook, the corresponding HARQ-ACK sub-codebooks are constructed separately according to the physical layer priority. For example, a high-priority HARQ-ACK sub-codebook is constructed based on the corresponding high-priority HARQ-ACK (if it exists), and a low-priority HARQ-ACK sub-codebook is constructed based on the corresponding low-priority HARQ-ACK (if it exists). The HARQ-ACK sub-codebooks with different physical layer priorities are encoded independently.

[0219] Option 3: The physical layer priority corresponding to SPS HARQ-ACK in the above operations must not be lower than the feedback priority (that is, the physical layer priority corresponding to the first SPS HARQ-ACK must be higher than or equal to the first priority).

[0220] The phrase "the corresponding physical layer priority is not lower than the feedback priority" mentioned here can be understood as follows: when triggering the feedback of SPS HARQ-ACK corresponding to a certain physical layer priority, it is necessary to ensure that SPS HARQ-ACK with a higher priority also provides feedback.

[0221] When the application is "the corresponding physical layer priority is not lower than the feedback priority" or thereafter, and the operation HARQ-ACK corresponds to only a single physical layer priority, if this single physical layer priority is the feedback priority, then the operation corresponding to Scheme 1 can be used; if this single physical layer priority is a physical layer priority other than the feedback priority, then the operation corresponding to Scheme 2 can be used.

[0222] When the application is "the corresponding physical layer priority is not lower than the feedback priority" or later, and the operation HARQ-ACK corresponds to more than one physical layer priority (i.e., corresponds to multiple physical layer priorities), then the operation corresponding to Scheme 2 can be used.

[0223] The above-mentioned solutions provided in the embodiments of this application are illustrated below.

[0224] For example, in Figure 4(This can be illustrated by showing One-shot triggering of re-transmission to obtain (Deferred) SPS HARQ-ACK.) The SPS HARQ-ACK corresponding to the SPS PDSCH transmitted in Slot 1 is expected to be transmitted in Slot 5 based on SPSPDSCH and HACK-ACK timing, i.e., Slot 5 is used as the initial slot. However, the SPS HARQ-ACK PUCCH resource determined in Slot 5 cannot be transmitted due to a conflict with a semi-static downlink symbol. Assuming that the SPS Config corresponding to this SPS PDSCH is configured to enable or apply the SPS HARQ-ACK deferral mechanism, then without applying the solution of this invention, based on the SPS HARQ-ACK deferral mechanism, the SPSHARQ-ACK corresponding to this SPS PDSCH is expected to be delayed until Slot 8 for transmission. After introducing the solution of this invention, based on the implementation of the network-side device, a one-time trigger DCI can be sent to the terminal in Slot 6 (Slot 6 serves as the trigger slot, or the second time unit), to trigger the terminal to respond with a Deferred SPS HARQ-ACK (i.e., the SPS HARQ-ACK corresponding to the aforementioned SPS PDSCH) in Slot 7. After the terminal responds with the SPS HARQ-ACK corresponding to the aforementioned SPS PDSCH in Slot 7 based on the indication of the one-time trigger DCI, there is no need to continue performing a deferral operation for the SPS HARQ-ACK corresponding to the aforementioned SPS PDSCH.

[0225] Specifically, it is in Figure 4 The SPS HARQ-ACK corresponding to the SPS PDSCH transmitted in Slot 1 occupies the PUCCH resources in its corresponding initial slot. Due to the conflict with the semi-static DL symbol, a deferral is triggered. Without the technical solution corresponding to this invention, based on the SPS HARQ-ACK deferral mechanism, it is expected to be delayed until the transmission in Slot 8. With the technical solution corresponding to this invention, it can be transmitted in Slot 7, thereby shortening the feedback delay.

[0226] in, Figure 4In this context, K1 represents the offset between the time unit (such as a time slot or sub-time slot) where the SPS PDSCH reception is located and the time unit where the initial feedback opportunity of the corresponding SPS HARQ-ACK is located, or K1 represents the offset between the time unit (such as a time slot or sub-time slot) where the DCI is triggered at one time and the time unit where the triggered HARQ-ACK feedback is located. "D" represents downlink and "U" represents uplink.

[0227] Example 1: (DCI transmission) Trigger retransmission of other codebooks and piggyback transmission of Deferred SPS HARQ-ACK bits;

[0228] When at least one valid HARQ-ACK bit (i.e., excluding padding negative acknowledgments NACK) in a HARQ-ACK codebook constructed within a certain Slot / sub-slot n (corresponding to the third time unit mentioned above) satisfies any of the following conditions (corresponding to the first condition mentioned above), retransmission of this HARQ-ACK codebook can be triggered using one-shot triggering of re-transmission:

[0229] (1) Not an SPS HARQ-ACK bit;

[0230] (2) is the SPS HARQ-ACK bit, but the corresponding SPS Config (i.e. SPS configuration item) does not have deferral configured;

[0231] (3) For the SPS HARQ-ACK bit, the corresponding SPS Config is configured with deferral, but deferral is not triggered;

[0232] (4) For the SPS HARQ-ACK bit, the corresponding SPS Config is configured with deferral, triggering defer, and the Slot / sub-slot n (corresponding to the third time unit above) is determined as the Target slot / sub-slot (corresponding to the target time unit above).

[0233] The aforementioned HARQ-ACK codebook may not have been actually transmitted due to relevant protocol mechanisms (such as deletion or cancellation due to SFI, Intra-UE UCI multiplexing (or priority processing), cancellation indication, etc.), or it may have been actually transmitted but was missed or incorrectly detected by the network side. In this case, the network side can use One-shot triggering of re-transmission to trigger the retransmission of this HARQ-ACK codebook, which corresponds to sending a one-time triggering downlink control information (DCI) to the terminal as mentioned above.

[0234] Understandably, when any valid HARQ-ACK bit (excluding padding NACK) in a HARQ-ACK codebook within a Slot / sub-slot is an SPS HARQ-ACK bit and is either triggered to defer or is further deferred, this HARQ-ACK codebook does not correspond to the regular case applicable to One-shot triggering of re-transmission within this Slot / sub-slot (the regular case here is that the HARQ-ACK codebook has a transmission opportunity in a Slot / sub-slot but is eventually deleted), but is only delayed in transmission. Therefore, One-shot triggering of re-transmission cannot be used to trigger the retransmission of this HARQ-ACK codebook.

[0235] When a HARQ-ACK codebook (i.e., "other codebooks", corresponding to the first HARQ-ACK codebook mentioned above) is reported in the feedback slot / sub-slot by a One-shot triggering DCI, if at least one Deferred SPS HARQ-ACK bit that satisfies the physical layer priority condition (corresponding to the second condition mentioned above) exists in the feedback slot / sub-slot, the triggered HARQ-ACK codebook can be used as a DG HARQ-ACK, and multiplexed with this at least one Deferred SPS HARQ-ACK bit, and then perform subsequent UCI multiplexing or prioritization operations as needed. In this scheme, it is also possible that the terminal transmits the triggered HARQ-ACK codebook, while the at least one delayed SPS HARQ-ACK bit continues to perform a delay operation.

[0236] The physical layer priority condition mentioned above can be any of the following (feedback priority can be similarly described above):

[0237] (1) Corresponding feedback priority (corresponding to the second priority mentioned above);

[0238] (2) Corresponds to any priority;

[0239] (3) The corresponding physical layer priority is not lower than the feedback priority.

[0240] In the above situation, when organizing the codebook within the slot / sub-slot:

[0241] (1) The triggered HARQ-ACK codebook can be used as the first sub-codebook. When there is still an initial transmission HARQ-ACK in the feedback slot / sub-slot, the triggered HARQ-ACK codebook can be concatenated after the codebook corresponding to the initial transmission HARQ-ACK to output the first sub-codebook.

[0242] (2) At least one of the above-mentioned Deferred SPS HARQ-ACK bits can be used to construct a second subcodebook based on predefined rules.

[0243] Then, the first sub-codebook and the second sub-codebook are concatenated to obtain the codebook within the feedback slot / sub-slot, for example, the second sub-codebook is concatenated after the first sub-codebook.

[0244] In summary, the solutions provided in this application provide a feasible implementation scheme for the combination or interoperability of One-shot triggering of re-transmission and SPS HARQ-ACK deferral, thereby enabling more flexible and dynamic control of SPS HARQ-ACK feedback and improving the reliability of SPS HARQ-ACK feedback to ensure the performance of SPS PDSCH transmission.

[0245] It should be noted that the information transmission method provided in this application embodiment can be executed by an information transmission device, or by a control module within the information transmission device for executing the information transmission method. This application embodiment uses an information transmission device executing the information transmission method as an example to illustrate the information transmission device provided in this application embodiment.
