In this embodiment of the present application, the "protocol" may refer to a standard protocol in the communication field, for example, may include an LTE protocol, an NR protocol, and related protocols applied in a future communication system, which is not limited in this application.
To facilitate a better understanding of the embodiments of the present application, a Type 1 (Type-1) HARQ-ACK feedback related to the present application is described.
In NR, two HARQ-ACK information generation methods are supported: type-1 semi-static HARQ-ACK codebook (semi-static HARQ-ACK codebook) and Type 2 (Type-2) dynamic HARQ ACK codebook (dynamic HARQ-ACK codebook). The embodiment of the application relates to a Type-1 semi-static HARQ-ACK codebook (simply referred to as a Type-1 feedback codebook or a Type-1 codebook).
Type-1 feedback codebook according to the number of configured serving cells, the feedback timing (timing) set of physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) to HARQ-ACK (a set of slot timing values K 1 ) A series of row indexes (a set of row indexes) R in a time resource allocation (Time Domain Resource Allocation, TDRA) table (table) determine the reception opportunities of candidate PDSCH in a semi-static manner, and thus determine the number of bits of corresponding ACK/NACK feedback information. Wherein each row in the tdrabable defines a PDCCH to PDSCH slot offset (slot offset) K0, a start symbol and length indication (start and length indicators, SLIV), and a PDSCH mapping type (mapping type). It can be appreciated that the Type-1 feedback codebook is based on the feedback timing set of PDSCH to HARQ-ACK (a set of slot timing values K 1 ) Determining a feedback window, K as shown in FIG. 2 1 Aggregation (K) 1 set) is configured as {1,2,4}, in the Type-1 feedback codebook contained in slotn, the corresponding feedback window is { slotn-1, slotn-2, slotn-4 }.
In the time slots included in the feedback window, the reception opportunities of the candidate PDSCH are determined according to the SLIV indicated by a set of row indexesR, that is, the number of ACK/NACK bits included in the Type-1 feedback codebook is not dependent on the number of actually received PDSCH, but is determined according to the reception opportunities of the candidate PDSCH in a semi-static configuration (that is, the maximum number of receivable PDSCH). The method has the advantages that the problem of ambiguity of the direct understanding of the ACK/NACK feedback codebook size by the terminal and the base station caused by the fact that the terminal does not receive part of PDSCH can be avoided, and the base station cannot correctly receive feedback information sent by the terminal.
However, this method has a disadvantage in that the feedback overhead is large, that is, there are reserved feedback information bits on all downlink resources that may transmit PDSCH. Since the terminal receives at most one PDSCH at the same time in one carrier, i.e., PDSCH candidate receiver 1 (occasions for candidate PDSCH receptions) in fig. 3 (slot shown in fig. 3 is { slot n-1, slot n-2, slot n-4} in fig. 2) and PDSCH candidate receivers 2, 3 will not be transmitted simultaneously. If corresponding feedback information bits are reserved for PDSCH candidate receivers 1,2, and 3 in the Type-1 feedback codebook, respectively, feedback information redundancy will be necessary, and the three PDSCH candidate receivers may share one feedback information bit. I.e. the terminal receives PDSCH in any of these three candidate receivers, with its corresponding ACK/NACK information mapped to one and the same bit. After this method is adopted, in the example shown in fig. 3, the slot is reserved with 2 ACK/NACK bits in the Type-1 feedback codebook (for example, single codeword transmission, that is, one PDSCH only carries one TB and corresponds to one bit of feedback information).
In addition, if the terminal does not have the capability of receiving more than one unicast (PDSCH) in one slot, all the 5 candidate PDSCH receivers in fig. 3 share one feedback information bit, i.e., PDSCH is received in any one of the five PDSCH candidate receivers, and its corresponding ACK/NACK information is mapped to one and the same bit.
For a better understanding of the embodiments of the present application, semi-persistent scheduling (Semi-Persistent Scheduling, SPS) transmissions relevant to the present application are described.
The SPS transmission is to reduce PDCCH overhead, and the base station transmits the active DCI once, so that multiple downlink transmissions that periodically occur can be scheduled. The implementation mechanism is as follows: each Serving Cell (Per-Serving Cell) and each Bandwidth Part (Per-BWP) are configured through radio resource control (Radio Resource Control, RRC) signaling, configuration information of each Serving Cell includes a period of the SPS configuration, HARQ processes, and the like, DCI scrambled by a configured scheduling radio network temporary identifier (Configured Scheduling Radio Network Temporary Identity, cs-RNTI) is activated/deactivated, and time-frequency resources occupied by the SPS PDSCH, a modulation coding scheme (Modulation and coding scheme, MCS) used, PDSCH to HARQ-ACK feedback timing, and the like are indicated in the activated DCI. For DCI indicated by SPS deactivation (SPS release), the terminal needs to feed back 1-bit HARQ-ACK information. The value is stated to be that only one TB can be transmitted in the SPS PDSCH of each period. The SPS PDSCH may also be referred to as SPS PDSCH resources, or SPS PDSCH time-frequency resources, without limitation.
In the NR system, one BWP supports at most one active SPS configuration, and the period is at least 10ms, and is mainly used to support Voice over IP (VoIP) services. In the industrial internet/ultra-reliable, low-latency communication (Industrial interest of Things/Ultra reliability and low latency communication, IIoT/URLLC) project, in order to support low-latency services using Downlink (DL) SPS, and adapt to multiple service characteristics with different periods, one BWP is supported to activate multiple SPS configurations at the same time, and the period of the SPS is supported to be 1slot at the minimum. For a plurality of SPS configurations, rel-16 supports three modes of respectively activating, respectively deactivating and jointly deactivating, wherein one DCI activates only one SPS configuration, and one DCI deactivates only one SPS configuration, and the joint deactivating can deactivate a plurality of SPS configurations simultaneously for one DCI. For both the respective deactivated DCI (separate release DCI) and joint deactivated DCI (joint release DCI) terminals need to feed back 1 bit HARQ-ACK information, for separate release DCI their HARQ-ACK information position in the Type-1HARQ-ACK codebook is the same as the HARQ-ACK information received by the SPS PDSCH of the corresponding SPS configuration in the Type-1HARQ-ACK codebook, and for joint release DCI their HARQ-ACK information position in the Type-1HARQ-ACK codebook is the same as the HARQ-ACK information position in the Type-1HARQ-ACK codebook of the SPS corresponding to the SPS configuration (configurations) with the smallest configuration index (index) in the configuration of SPS configuration.
To facilitate a better understanding of the embodiments of the present application, multiple PDSCH/PUSCH single DCI (multi-PDSCH/PUSCH with a single DCI) transmissions relevant to the present application are described.
The work item "Extending current NR operation to GHz" supports the feature that one DCI schedules multiple PDSCH or PUSCH, each of which is used to carry a different TB transmission, in order to support a larger subcarrier spacing, increasing PDCCH blind-check period. Some of the indication fields in the DCI are shared by all PDSCH (e.g., MCS, etc.), and some are per PDSCH/PUSCH (e.g., redundancy version (Redundancy Version, RV), new data indication (New Data Indicator, NDI), etc. For the time domain resource indication, the multiplexing function of multi-PUSCH in NR-U is that the TDRA table is expanded, and each row can indicate SLIV, mapping type and slot offset of more than one PDSCH/PUSCH. In addition, HARQ-ACKs corresponding to multiple PDSCH are fed back in the same PUCCH, and PDSCH-to-harq_ feedback timing indicator indication field in DCI is used to indicate slot offset from the slot in which the last scheduled PDSCH is located to the slot in which their HARQ-ACK information is carried. It should be noted that the feature that one DCI schedules multiple PDSCH or PUSCH is not applicable to SPS, i.e., SPS PDSCH does not support transmission of multiple PDSCH carrying multiple TBs per period.
In order to facilitate better understanding of the embodiments of the present application, technical problems that exist in the present application are described.
For XR/CG traffic as described in the background, with larger frame size and/or quasiperiodic features, when a data frame arrives, it needs to be split into multiple TBs for transmission. Taking the data rate of 30Mbps as an example required by AR/VR, the average size of each video frame (video frame) can reach 62500bytes, and if the video frame is transmitted with 30khz scs,100mhz bandwidth, 16QAM modulation order, 1/3 code rate, approximately 10 slots (slots) are needed to complete one video frame transmission, i.e. the video frame can be split into 10 TBs for transmission.
The periodic service is more suitable for scheduling by using SPS, so that PDCCH resources can be saved, and meanwhile, the power consumption of monitoring PDCCH by the terminal equipment can be reduced. In addition, for DCI of SPS deactivation indication, the terminal device needs to feed back 1-bit HARQ-ACK information. When PDSCH resources in the SPS period support transmission of one TB, the position of the HARQ-ACK information in the Type-1HARQ-ACK codebook is the same as the position of the HARQ-ACK information received by the SPS PDSCH of the corresponding SPS configuration (or SPS configuration of the lowest index) in the Type-1HARQ-ACK codebook. Therefore, how to transmit XR/CG traffic through SPS and how to determine HARQ-ACK information corresponding to DCI of SPS deactivation indication are issues to be resolved.
Based on the above-mentioned problems, the present application proposes a method and an apparatus for wireless communication, when a first DCI is used to deactivate at least one SPS configuration, a position of HARQ-ACK information corresponding to the first DCI in a HARQ-ACK codebook is the same as a position of HARQ-ACK information corresponding to a first SPSPDSCH in an SPS period corresponding to the first SPS configuration in the at least one SPS configuration, so that a terminal device and a network device understand the position of HARQ-ACK information corresponding to the first DCI in the HARQ-ACK codebook consistently, and are helpful for successfully demodulating HARQ-ACK information. The first SPS configuration is, for example, a unique SPS configuration deactivated by the first DCI, or an SPS configuration with a lowest SPS configuration index from among a plurality of SPS configurations deactivated by the first DCI, without limitation.
The technical scheme of the present application is described in detail below through specific embodiments.
Fig. 4 is a schematic flow chart of a method 400 of wireless communication according to an embodiment of the present application, as shown in fig. 4, the method 400 may include at least some of the following:
s410, the network device transmits a first DCI for deactivating at least one SPS configuration, where one or more SPS configurations of the at least one SPS configuration include at least one SPSPDSCH within an SPS period corresponding to the SPS configuration. Correspondingly, the terminal equipment receives the first DCI.
In some embodiments, the first DCI may be referred to as an SPS deactivation indication DCI, SPSPDSCHrelease, etc., without limitation.
In some embodiments, the SPS configuration may include, without limitation, SPS period, HARQ process number, PUCCH Identification (ID), time-frequency resources of SPS PDSCH, and the like.
S420, the terminal equipment sends the HARQ-ACK information corresponding to the first DCI. The position of the HARQ-ACK information corresponding to the first DCI in the HARQ-ACK codebook is the same as the position of the HARQ-ACK information corresponding to the first spdsch in the HARQ-ACK codebook, where the first spdsch is one SPS PDSCH in an SPS period corresponding to a first SPS configuration, and the at least one SPS configuration includes the first SPS configuration. Correspondingly, the network device may receive HARQ-ACK information corresponding to the first DCI.
For example, the terminal device may generate the HARQ-ACK codebook, and send the HARQ-ACK codebook to the network device, where the HARQ-ACK codebook includes HARQ-ACK information corresponding to the first DCI. Optionally, the HARQ-ACK codebook may further include HARQ-ACK information corresponding to the SPSPDSCH within the SPS period. As an example, the HARQ-ACK codebook may be a Type-1HARQ-ACK codebook, which is not limited in this application.
In some embodiments, at least one SPS dsch resource in an SPS period corresponding to the above-described SPS configuration (i.e., one or more of the at least one SPS configuration) may support transmission of at least one TB, which may enable multi-TB (multi-TB) transmission in the SPS period. For example, the number of at least one SPSPDSCH within the SPS period may be N and the number of at least one TB supporting transmission is M, where M, N is a positive integer. Therefore, the embodiment of the application can efficiently transmit the XR/CG service, for example, in the case that one DCI only supports one active SPS configuration, fewer SPS periods are required, for example, 1 or 2 SPS periods can be used to transmit and complete one XR/CG frame, which is beneficial to reducing the scheduling delay and improving the capacity of the XR/CG service.
In some embodiments, M may be less than or equal to N. Illustratively, when the configured maximum number of codewords is 1, at most one TB can be transmitted on one of the SPSPDSCH resources.
Therefore, when the first DCI is used for deactivating at least one SPS configuration, the embodiment of the present application can realize that the position of HARQ-ACK information corresponding to the first DCI in the HARQ-ACK codebook is the same as the position of HARQ-ACK information corresponding to the first spdsch in the SPS period corresponding to the first SPS configuration in the at least one SPS configuration, so that the terminal device and the network device understand that the position of HARQ-ACK information corresponding to the first DCI in the HARQ-ACK codebook is consistent, and are helpful for successfully demodulating HARQ-ACK information.
It should be noted that, if the determining manner of the position of the HARQ-ACK information corresponding to the first DCI in the HARQ-ACK codebook is lacking when the first DCI is used to deactivate the SPS configuration of the at least one SPS configuration or the SPS period corresponding to the SPS configurations includes the SPSPDSCH, the terminal device and the network device may understand that the position of the HARQ-ACK information corresponding to the first DCI in the HARQ-ACK codebook is inconsistent, which may cause the HARQ-ACK demodulation to fail.
It should be noted that, the SPS configuration described in the embodiments of the present application may refer to one or more of at least one SPS configuration for deactivation of the first DCI, which is not limited. For example, a first SPS configuration, or a second SPS configuration, etc.
In some alternative embodiments, the network device may also send configuration information for configuring time-frequency resources of at least one SPSPDSCH within the SPS period to which the SPS configuration corresponds. Correspondingly, the terminal device may receive the configuration information, and determine, according to the configuration information, a time-frequency resource of at least one SPS PDSCH in the SPS period corresponding to the SPS configuration.
As an example, one SPS period may include a plurality of slots, and one SPSPDSCH in one SPS period may occupy at least a portion of symbols in one slot. Further, at least one SPS PDSCH in one SPS period may occupy the same symbol in the corresponding slot or occupy different symbols, which is not limited in this application. For another example, at least one SPS PDSCH within one SPS period may occupy consecutive time slots, or non-consecutive time slots, which is not limited in this application.
In some optional embodiments, the network device may also transmit a second DCI for activating the at least one SPS configuration. Correspondingly, the terminal device may receive the second DCI. In some embodiments, the terminal device may not transmit HARQ-ACK information corresponding to the second DCI. In this way, the terminal device may transmit a TB in an SPS period corresponding to the at least one SPS configuration based on the indication of the second DC, enabling data transmission between the network device and the terminal device.
Illustratively, the network device may send the second DCI prior to step 410, which is not limited in this application. That is, after the second DCI activates at least one SPS configuration, the network device may transmit the first DCI to deactivate the at least one SPS configuration, and the terminal device transmits HARQ-ACK information corresponding to the first DCI to the network device.
In some optional embodiments, when the network device does not configure the time-frequency resource of at least one SPS PDSCH in the SPS period corresponding to the SPS configuration by the configuration information, the second DCI may further be used to indicate the time-frequency resource of the at least one SPS dsch. That is, when at least one SPS configuration is activated by the second DCI, the network device may also indicate, via the second DCI, video resources of at least one SPS PDSCH within an SPS period corresponding to one or more of the at least one SPS configuration.
In some alternative embodiments, the first DCI may be DCI (separate/single SPSPDSCH release DCI) that deactivates the spdsch separately/individually, i.e. one first DCI may deactivate one SPS configuration including at least one spdsch within the corresponding SPS period. As another example, the first DCI may be a single DCI (multiple SPS PDSCH release by a single DCI format) for releasing a plurality of SPS configurations, i.e., a single first DCI may deactivate a plurality of SPS configurations simultaneously, one (or each) of which includes at least one SPSPDSCH within a corresponding SPS period.
When the first DCI is separate/single SPSPDSCH release DCI, the at least one SPS configuration may include the first SPS configuration and not include other SPS configurations in step 410.
When the first DCI is multiple SPS PDSCH release by a single DCI format, the at least one SPS configuration may include at least two SPS configurations, i.e., the number of SPS configurations in the at least one SPS configuration may be more than two. At this time, the at least two SPS configurations include the first SPS configuration described above, as well as other SPS configurations.
In some alternative embodiments, the index of the first SPS configuration is lowest (or smallest) among the indexes corresponding to the at least two SPS configurations. That is, the first SPS configuration may be, without limitation, an SPS configuration corresponding to a lowest (or smallest) SPS configuration index of the at least two SPS configurations.
Alternatively, in other optional embodiments, the index of the first SPS configuration may be the highest (or the largest) of the indexes corresponding to the at least two SPS configurations, or other indexes of the indexes corresponding to the at least two SPS configurations, which is not limited.
Alternatively, the first spdsch may be the first spdsch in the SPS period corresponding to the first SPS configuration, or the last spdsch, or other spdsch, which is not limited.
In some optional embodiments, the first SPS PDSCH described above may be configured by the network device through signaling. For example, the network device may indicate, through higher layer signaling configuration or physical layer downlink control signaling, that the HARQ-ACK information corresponding to the first DCI is located in the same position in the HARQ-ACK codebook as the HARQ-ACK information corresponding to the first SPS PDSCH, and that the first SPS PDSCH is one (such as the first SPS PDSCH, or the last SPS PDSCH) SPS PDSCH in an SPS period corresponding to the SPS configuration (e.g., the first SPS configuration) that the first DCI deactivates.
In some optional embodiments, the position of the HARQ-ACK information corresponding to the first DCI in the HARQ-ACK codebook may be defined by a protocol to be the same as the position of the HARQ-ACK information corresponding to the first SPS PDSCH in the HARQ-ACK codebook, and the first SPS PDSCH is one (such as the first SPS PDSCH, or the last SPS PDSCH) in an SPS period corresponding to the SPS configuration (such as the first SPS configuration) deactivated by the first DCI. For example, the protocol may define a location of HARQ-ACK information corresponding to a first DCI in a HARQ-ACK codebook, where the location of HARQ-ACK information corresponding to a first SPS PDSCH or a last SPS PDSCH in an SPS period corresponding to one of at least one SPS configuration (e.g., a first SPS configuration) for which the first DCI is used for deactivation is the same.
In some optional embodiments, the first SPS PDSCH is a first valid PDSCH or a last valid PDSCH within the SPS period corresponding to the first SPS configuration, where the valid PDSCH includes at least one of:
PDSCH not containing symbols configured as uplink by time division duplex (Time Division Duplexing, TDD) uplink and downlink configuration;
PDSCH not containing symbols configured as flexible (flexible) by TDD uplink and downlink configuration;
PDSCH not including symbols indicated as uplink by a Slot Format Indicator (SFI);
PDSCH not containing symbol indicated as flexible by SFI;
the PDSCH that the terminal does not require to receive is not included.
As an example, the TDD uplink and downlink configuration includes at least one of TDD-UL-DL-ConfigurationCommon, TDD-UL-DL-configuration and the like, for example.
As an example, PDSCH that the terminal does not require to receive may include at least one of:
an SPS PDSCH having a plurality of overlapping (overlapping) slots in one slot, the terminal not requiring a PDSCH to be received according to the rule specified in TS 38.214 section 6;
the received PDSCH is not required according to the terminal's ability to receive the number of PDSCH in one slot.
Note that, in the case where the terminal does not require the PDSCH to be received, the behavior of the network device may not be limited. For example, the network device may not transmit these PDSCH.
In some embodiments, "do not include symbols configured as uplink by TDD uplink-downlink configuration," can also be described as: "symbols including symbol non-overlapping configured as uplink by TDD uplink and downlink configuration"; "a symbol that does not include a symbol configured as a flexible by TDD uplink and downlink configuration" may also be described as "a symbol that includes a symbol that is not overlapping with a symbol configured as a flexible by TDD uplink and downlink configuration"; "not including a symbol indicated as uplink by the SFI" can also be described as "including a symbol not overlapping with a symbol indicated as uplink by the SFI"; the "symbol not including the symbol indicated as flexible by the SFI" may also be described as "symbol including a symbol that is not overlapped with the symbol indicated as flexible by the SFI", which is not limited in this application.
Fig. 5 shows a specific example of a method for determining HARQ-ACK information corresponding to DCI of an SPS deactivation instruction. For example, in fig. 5, the network side (e.g., the network device) may configure/indicate the first SPS configuration for the terminal device through the higher layer signaling/physical layer downlink control information, and configure/indicate that the SPS period P corresponding to the first SPS configuration includes n=4 SPS PDSCH resources, which may be used to transmit 4 TBs, or less than 4 TBs. One SPS period P may include 6 slots (which may be respectively represented as slot 1 through slot 6), wherein each of slots 1 through 4 may include one SPS PDSCH resource.
It will be appreciated that fig. 5 only shows an example of one SPS period, and is not limited to the scheme of the embodiment of the present application, for example, the time-frequency resources occupied by 4 SPS PDSCH resources in SPS period P may be the same or different; for example, 4 SPS PDSCH resources within SPS period P may occupy consecutive slots, or non-consecutive slots, without limitation.
With continued reference to fig. 5, the network device transmits DCI (one example of a first DCI) of an SPS deactivation indication in time slot 5, which may be used to release the first SPS configuration, and may indicate, in the DCI, the corresponding symbol feedback of HARQ-ACK information corresponding to the DCI in time slot 6 via K1. Alternatively, the network device may configure the terminal device to use a Type-1HARQ-ACK codebook. Then, in the symbol of the HARQ-ACK information corresponding to the DCI of the SPS deactivation instruction in the slot 6, the position of the HARQ-ACK information corresponding to the DCI in the HARQ-ACK codebook may be the same as the position of the HARQ-ACK information corresponding to the first SPS PDSCH in the SPS period P of the first SPS configuration in the HARQ-ACK codebook, that is, the position of the HARQ-ACK information corresponding to the DCI in the HARQ-ACK codebook may be determined by the time domain resource corresponding to the first SPS PDSCH in the SPS period P of the first SPS configuration in the slot (i.e., the time slot 5) in which the DCI is located (i.e., the dashed shaded box in fig. 5).
As a specific example, the network side may configure K1set to include {5,4,3,2,1}, that is, the Type-1HARQ-ACK codebook fed back by slot 6 in fig. 5 needs to include HARQ-ACKs corresponding to candidate PDSCH receivers on slots 1 through 5. In addition, the TDRA table configured on the network side includes 4 SLIVs, which correspond to the time domain positions (e.g., symbol positions) occupied by the 4 SPS PDSCH of fig. 5, respectively. Assuming that the PDSCH candidate receivers 1 to 4 are in one slot, but since the symbols occupied by the SPS PDSCH 1 to 3 are overlap in the same slot, the corresponding PDSCH candidate receiver 1 to 3 only needs to reserve 1 bit HARQ-ACK information, and the candidate PDSCH receiver 4 may not overlap with the candidate PDSCH receiver 1, and therefore needs to reserve 1 bit HARQ-ACK information. Therefore, 2 bits of HARQ-ACK information bits need to be reserved in each slot.
With continued reference to fig. 5, based on the above K1set and TDRA table, the Type-1HARQ-ACK codebook fed back in slot 6 may contain 5*2 =10 bits of HARQ-ACK information, where 5 represents slot 1 to slot 5, and 2 represents 2 bits reserved for candidate PDSCH receivers of each slot. Let the 10-bit HARQ-ACK information be a1 to a10, respectively, wherein the HARQ-ACK information bits corresponding to the slot 1 are a1, a2, the HARQ-ACK information bits corresponding to the slot 2 are a3, a4, the HARQ-ACK information bits corresponding to the slot 3 are a5, a6, the HARQ-ACK information bits corresponding to the slot 4 are a7, a8, and the HARQ-ACK information bits corresponding to the slot 5 are a9, a10. Since in fig. 5, the SPS PDSCH in the slots 1 to 3 may correspond to the 1-bit HARQ-ACK information positions reserved for the PDSCH candidate receivers 1 to 3 and the SPS PDSCH in the slot 4 may correspond to the 1-bit HARQ-ACK information positions reserved for the PDSCH candidate receiver 4, the positions of the HARQ-ACK information corresponding to the SPS PDSCH in the slots 1 to 4 in fig. 5 are a1, a3, a5, a8, respectively.
Further, the position of the HARQ-ACK information corresponding to the DCI indicated by SPS deactivation is a9, and the position of the HARQ-ACK corresponding to the PDSCH candidate receiver corresponding to the dashed box in the instant message 5.
Alternatively, in fig. 5, the network device may define through signaling configuration or a protocol, where the position of HARQ-ACK information corresponding to DCI of the SPS deactivation instruction in the HARQ-ACK codebook is the same as the position of HARQ-ACK information corresponding to the first SPS PDSCH in the SPS period of the first SPS configuration in the HARQ-ACK codebook.
Alternatively, the DCI of the SPS deactivation indication of fig. 5 may be used to release the first SPS configuration. Or alternatively, the DCI of the SPS deactivation indication of fig. 5 may be used to release at least two SPS configurations, including the first SPS configuration described above, which may be the SPS configuration with the lowest SPS configuration index of the at least two SPS configurations.
Fig. 6 shows another specific example of the determination method of HARQ-ACK information corresponding to DCI of SPS deactivation indication. Unlike fig. 5, in the symbol of HARQ-ACK information corresponding to DCI of the SPS deactivation indication in the time slot 6, the position of HARQ-ACK information corresponding to the DCI in the HARQ-ACK codebook may be the same as the position of HARQ-ACK information corresponding to the last SPS PDSCH in the SPS period P of the first SPS configuration in the HARQ-ACK codebook, that is, the position of HARQ-ACK information corresponding to the DCI in the HARQ-ACK codebook may be determined by the time domain resource of the time slot (i.e., the dashed-line hatched box in fig. 6) in which the DCI is located, which corresponds to the last SPS PDSCH in the SPS period P of the first SPS configuration.
In some optional embodiments, the SPS period corresponding to the first SPS configuration may include P groups of SPS PDSCH, and each group of SPS dsch may include at least one spdsch therein. The first SPS PDSCH may be one SPS PDSCH of an xth group of the P group of SPS PDSCH, where X is less than or equal to P, X, P is a positive integer. Alternatively, P may be smaller than N described above. Alternatively, the first SPS PDSCH may be the first SPS PDCH in the X-th group of SPS PDSCH, or the last SPS PDSCH, which is not limited.
Therefore, according to the embodiment of the application, the position of the HARQ-ACK information corresponding to the first DCI in the HARQ-ACK codebook can be determined according to the position of the HARQ-ACK information corresponding to one SPS PDSCH in a group of SPS PDSCH in the SPS period corresponding to the first SPS configuration, so that the determination mode of the position of the HARQ-ACK information corresponding to the DCI of the SPS deactivation instruction in the HARQ-ACK codebook can be more flexibly implemented.
As an example, a feedback manner of HARQ-ACK information corresponding to at least one SPSPDSCH within one SPS period, for example, whether HARQ-ACK information corresponding to the SPSPDSCH can be fed back on the same PUCCH, and/or whether the HARQ-ACK information belongs to the same bundling group (bundling group) may be used as a grouping basis of the SPSPDSCH. For example, if HARQ-ACK information corresponding to multiple spdschs can be transmitted on the same PUCCH and/or belong to the same bundling scheme, that multiple spdschs can be used as a group of spdschs. Alternatively, the HARQ-ACK information corresponding to the SPSPDSCH may be included in the HARQ-ACK codebook described above, which is not limited in this application.
For example, in the case where each SPS PDSCH transmits one TB, the HARQ-ACK information corresponding to a group of SPS PDSCH may be bundled (bundled) into HARQ-ACK information bits of the same bundling group by a logical and/or logical or operation. As an example, the number of HARQ-ACK information bits in one bundling group may be 1, or 2, or more, which is not limited in this application.
Optionally, HARQ-ACK information corresponding to a group of SPS PDSCH in the P group of SPS PDSCH is transmitted on the same physical uplink control channel PUCCH, and/or HARQ-ACK information corresponding to a group of SPS PDSCH in the P group of SPS PDSCH belongs to the same bundling group.
In some optional embodiments, the HARQ-ACK information corresponding to the at least one SPS PDSCH in the SPS period corresponding to the first SPS configuration may include P groups of HARQ-ACK information, each group of HARQ-ACK information includes at least one HARQ-ACK information, the first SPS PDSCH may be an SPS PDSCH corresponding to the first HARQ-ACK information, the first HARQ-ACK information may be one of the X-th group of HARQ-ACK information in the P groups of HARQ-ACK information, and X, P may be described above.
Optionally, the first HARQ-ACK information may be the first HARQ-ACK information in the X-th group HARQ-ACK information, or the SPS PDSCH corresponding to the last HARQ-ACK information, which is not limited.
Therefore, according to the embodiment of the application, the position of the HARQ-ACK information corresponding to the first DCI in the HARQ-ACK codebook may be determined according to the position of the first HARQ-ACK information in the HARQ-ACK codebook, where the first HARQ-ACK information is one of a certain group of HARQ-ACK information obtained by grouping the HARQ-ACK information corresponding to at least one SPS PDSCH corresponding to the first SPS configuration, so that the determination manner of the position of the HARQ-ACK information corresponding to the DCI of the SPS deactivation indication in the HARQ-ACK codebook may be more flexibly implemented.
Optionally, one set of HARQ-ACK information in the P sets of HARQ-ACK information may be transmitted on the same PUCCH, and/or one set of HARQ-ACK information may belong to the same bundling group. In some embodiments, the feedback manner of the HARQ-ACK information corresponding to at least one spdsch in one SPS period may be used, for example, whether the HARQ-ACK information corresponding to the spdsch may be fed back on the same PUCCH, and/or whether the HARQ-ACK information belongs to the same bundling group (bundling group), as a grouping basis of the HARQ-ACK information. For example, if HARQ-ACK information corresponding to multiple spdschs can be transmitted on the same PUCCH and/or belong to the same bundling uplink, that multiple HARQ-ACK information can be used as a set of HARQ-ACK information.
Therefore, in the embodiment of the present application, by grouping a plurality of SPS PDSCH in an SPS period (or grouping a plurality of HARQ-ACK information), HARQ-ACK information corresponding to the SPS PDSCH in the same group (or HARQ-ACK information in the same group) is transmitted on the same PUCCH, so that the time delay of HARQ-ACK feedback information can be effectively reduced.
In some alternative embodiments, X may be determined from the time domain position of the first DCI. Here, the time domain position of the first DCI may be referred to as a reception position, and is not limited.
For example, when the receiving position of the first DCI is located before the last PDSCH of the M-th group of SPS PDSCHs, the position of HARQ-ACK feedback information corresponding to the first DCI in the HARQ-ACK codebook is the same as the position of HARQ-ACK information corresponding to one SPS PDSCH of the M-th group of SPS PDSCHs in the SPS period corresponding to the SPS configuration deactivated by the first DCI.
For another example, when the reception position of the first DCI is located before the HARQ-ACK information corresponding to the M-th group of SPS PDSCHs, the position of the HARQ-ACK feedback information corresponding to the first DCI in the HARQ-ACK codebook is the same as the position of the HARQ-ACK information corresponding to one of the M-th group of SPS PDSCHs in the SPS period corresponding to the SPS configuration deactivated by the first DCI.
In some alternative embodiments, X may be determined according to a time domain position of HARQ-ACK information corresponding to the first DCI.
For example, when the HARQ-ACK information corresponding to the first DCI and the HARQ-ACK information corresponding to the M-th group of SPS PDSCHs are fed back on the same PUCCH, the position of the HARQ-ACK feedback information corresponding to the first DCI in the HARQ-ACK codebook is the same as the position of the HARQ-ACK information corresponding to one of the M-th group of SPS PDSCHs in the SPS period corresponding to the SPS configuration deactivated by the first DCI.
In some alternative embodiments, the X may be configured by the network device through signaling, or defined by a protocol, without limitation.
In some optional embodiments, the first SPS PDSCH may be configured by the network device as a first one of the at least one SPS PDSCH in the X-th group of SPS PDSCH, or as a last SPS PDSCH, by signaling. For example, the network device may be configured through higher layer signaling, or indicated by physical layer downlink control signaling, without limitation.
In some optional embodiments, the first SPS PDSCH may be defined by a protocol as a first one of at least one SPS PDSCH in the X-th group of SPS PDSCH, or a last SPS PDSCH.
In some optional embodiments, the first SPS PDSCH may be the first valid PDSCH or the last valid PDSCH in the X-th group of SPS PDSCH, and in particular, the valid PDSCH may be referred to above and will not be described again.
Fig. 7 shows a specific example of a method for determining HARQ-ACK information corresponding to DCI of an SPS deactivation instruction. For example, in fig. 7, the network side (e.g., the network device) may configure the first SPS configuration for the terminal device through higher layer signaling, and configure/indicate that n=8 SPS PDSCH resources are included in the SPS period P of the first SPS configuration, and may be used to transmit 8 TBs, or less than 8 TBs. Wherein one SPS period P may include 12 slots, each of the first 4 slots (i.e., slots 1 through 4) may include one SPS PDSCH resource, i.e., a first group (group 1) of SPS PDSCH resources, and each of the 7-10 slots (i.e., slots 7 through 10) may include one SPS PDSCH resource, i.e., a second group (group 2) of SPS PDSCH resources. For example, HARQ-ACK information (e.g., bits) corresponding to SPS PDSCH of each group may be fed back on the same PUCCH, or a group of HARQ-ACK information may belong to the same bundling group.
It will be appreciated that fig. 7 only shows an example of one SPS period, and is not limited to the configuration of the solution in the embodiment of the present application, for example, the time-frequency resources occupied by 8 SPS PDSCH resources in one SPS period P may be the same or different; for another example, 8 SPS PDSCH resources within one SPS period P may occupy consecutive time slots, or non-consecutive time slots, without limitation.
Optionally, in fig. 7, the terminal device may determine, according to the receiving location of the DCI of the SPS deactivation indication, that the location of HARQ-ACK information corresponding to the DCI of the SPS deactivation indication in the HARQ-ACK codebook is the same as the location of HARQ-ACK information corresponding to one (such as the first or last) SPS PDSCH in the group of SPS PDSCH in the SPS period of the first SPS configuration in the HARQ-ACK codebook.
As an example, referring to fig. 7, when the network device transmits DCI of an SPS deactivation indication (one example of first DCI) in slot 5 of SPS period P (i.e., a slot after a first group of SPS PDSCH), the DCI may be used to release the first SPS configuration and indicate corresponding symbol feedback of HARQ-ACK information corresponding to the DCI in slot 6 through K1 in the DCI. Alternatively, the network device may configure the terminal device to use a Type-1HARQ-ACK codebook. Then, in the symbol of the HARQ-ACK information corresponding to the DCI of the SPS deactivation instruction in the time slot 6, the position of the HARQ-ACK information corresponding to the DCI in the HARQ-ACK codebook may be the same as the position of the HARQ-ACK information corresponding to the first SPS PDSCH in the first group of SPS PDSCH in the SPS period P of the first SPS configuration, that is, the position of the HARQ-ACK information corresponding to the DCI in the HARQ-ACK codebook may be determined by the time domain resource of the position corresponding to the first SPS PDSCH in the first group of SPS PDSCH in the SPS period P of the first SPS configuration in the time slot where the DCI is located (i.e., the dashed hatched box of the time slot 5 in fig. 7).
As another example, with continued reference to fig. 7, when the network device transmits DCI of an SPS deactivation indication (one example of a first DCI) in slot 11 of SPS period P (i.e., a slot after a second set of SPS PDSCH), the DCI may be used to release the first SPS configuration and indicate, in the DCI, the corresponding symbol feedback of the HARQ-ACK information corresponding to the DCI in slot 12 via K1. Alternatively, the network device may configure the terminal device to use a Type-1HARQ-ACK codebook. Then, in the symbol of the HARQ-ACK information corresponding to the DCI of the SPS deactivation instruction in the time slot 12, the position of the HARQ-ACK information corresponding to the DCI in the HARQ-ACK codebook may be the same as the position of the HARQ-ACK information corresponding to the last SPS PDSCH in the second group of SPS PDSCH in the SPS period P of the first SPS configuration in the HARQ-ACK codebook, that is, the position of the HARQ-ACK information corresponding to the DCI in the HARQ-ACK codebook may be determined by the time domain resource of the time slot in which the DCI is located, where the HARQ-ACK information corresponding to the last SPS PDSCH in the second group of SPS PDSCH in the SPS period P of the first SPS configuration (i.e., the dashed hatched box of the time slot 11 in fig. 7).
In fig. 7, the network device may transmit DCI indicating SPS deactivation in one of time slots 5 and 11.
Optionally, in fig. 7, the network device may also define, through signaling configuration or a protocol, that the position of HARQ-ACK information corresponding to DCI of the SPS deactivation instruction in the HARQ-ACK codebook is the same as the position of HARQ-ACK information corresponding to one (such as the first or last) SPS PDSCH in the X-th group (such as the first group or the second group) of SPS PDSCH in the SPS period of the first SPS configuration.
Alternatively, the DCI of the SPS deactivation indication of fig. 7 may be used to release the first SPS configuration. Or alternatively, the DCI of the SPS deactivation indication of fig. 7 may be used to release at least two SPS configurations, including the first SPS configuration described above, which may be the SPS configuration with the lowest SPS configuration index of the at least two SPS configurations.
In some alternative embodiments, the length of time (time duration for the reception of SPS PDSCHs) of SPS PDSCH reception included within a corresponding SPS period of an SPS configuration (e.g., one or more of the at least one SPS configurations described above, such as the first SPS configuration) is less than or equal to the length of time resulting from the SPS period of the SPS configuration. That is, the terminal device does not expect the length of time that at least one SPS PDSCH included in the SPS period corresponding to the SPS configuration is received to be greater than the length of time that would result from the SPS period of the SPS configuration (theUE is not expected to be configured with the time duration for the reception of PDSCH-AggregationFactor repetitions, in SPS-Config if configured, or across the PDSCH-AggregationFactor in PDSCH-config other, larger than the time duration derived by the periodicity P obtained from the corresponding SPS-config.). Because the time length of receiving at least one SPS PDSCH in the SPS period corresponding to the SPS configuration is smaller than or equal to the time length obtained by the SPS period of the SPS configuration, the resource conflict of the SPS PDSCH in different SPS periods can be avoided, and the HARQ process conflict corresponding to the SPS PDSCH in different SPS periods can be further avoided, so that the correct data transmission can be facilitated.
When the SPS period supports multi-TB scheduling, the time length of at least one SPS PDSCH received in the SPS period corresponding to the SPS configuration is less than or equal to the time length obtained by the SPS period corresponding to the SPS configuration, that is, the technical scheme that the terminal device does not expect the time length of at least one SPS PDSCH received in the SPS period corresponding to the SPS configuration to be greater than the time length obtained by the SPS period corresponding to the SPS configuration does not depend on the determination mode of the HARQ-ACK information corresponding to the first DCI. That is, the two schemes may be implemented in combination or may be implemented independently of each other, which is not limited in this application.
It should be further noted that, when configuring/indicating SPS PDSCH resources and SPS periods, the network device may meet configuration/indication that is not expected by the terminal device, but the embodiment of the present application does not limit the behavior of the network device. Alternatively, if the configuration/indication of the network device does not satisfy the configuration/indication that the terminal device does not expect, the terminal device may consider the configuration/indication of the network device to be an error case.
Fig. 8 shows an example of a reception time length of the SPS PDSCH in the SPS period expected by the terminal device. As shown in fig. 8, a network side (e.g., a network device) may configure SPS configuration for a terminal device, including a period parameter P, and may configure each SPS period P to include n=4 SPS PDSCH resources, where a time slot, a symbol, etc. occupied by the 4 SPS PDSCH resources may be configured by the network side through higher layer signaling, or indicated by downlink control information. In fig. 8, the length of time for which at least one SPS PDSCH included in each SPS period P is received is less than (or equal to) the length of time derived from the SPS period of the SPS configuration, i.e., the length indicated by the period parameter P.
In addition, fig. 9 shows an example of the reception time length of the SPS PDSCH in the SPS period which is not expected by the terminal device. The SPS configuration of the corresponding network side configuration in fig. 9 is the same as that in fig. 8. In fig. 9, the length of time for which at least one SPS PDSCH is received included within each SPS period P is greater than the length of time resulting from the SPS period of the SPS configuration, i.e., the length indicated by the period parameter P.
