Description

1 / 80 HARQ-ACK FEEDBACK METHOD AND DEVICE, TERMINAL AND BASE STATION CROSS-REFERENCE OF RELATED REQUEST

[0001] This application claims priority over patent application no. CN 202010281099.2 filed on April 10, 2020, which is incorporated herein by reference in its entirety. FIELD OF TECHNIQUE

[0002] This disclosure relates to the field of wireless technologies and, in particular, to a HARQ-ACK feedback method and device, a terminal and a base station. BACKGROUND

[0003] In the 5G NR (5th Generation New Radio) system, Scheduling Semi-persistent scheduling (SPS) transmission of Physical Downlink Shared Channel (PDSCH) and transmission of Dynamic Downlink Control Channel (PDSCH) with a corresponding Physical Downlink Control Channel (PDCCH) are supported, i.e., PDSCH is transmitted by a PDCCH schedule.

[0004] When there is a service to perform SPS transmission, the base station can activate the terminal to perform SPS transmission according to the configured SPS periodicity by transmitting a PDCCH indicating SPS activation. When SPS resources are no longer needed, the base station can release previously allocated SPS resources by sending a PDCCH indicating SPS resource release, and to ensure that the base station can accurately know if the PDCCH indicating SPS resource release (which may also be called an SPS PDSCH release) is successfully received by the terminal, the Petition 870220092961, dated 10 / 10 / 2022, page 5 / 332 2 / 80 Hybrid Automatic Repeat Request-Acknowledgement (HARQ-ACK) feedback needs to be executed in PDCCH which indicates SPS resource release.

[0005] In R16, the configuration of transmitting more than 1 SPS on a carrier (specifically, on a bandwidth portion (BWP) on a carrier) is supported, and the minimum period of each SPS can be 1 ms. When there are multiple PDSCH transmissions of SPS corresponding to SPS configurations on a carrier, it may happen that there is at least one PDSCH transmission of SPS corresponding to an SPS configuration in each interval. For a terminal that supports only a maximum of a of PDSCH point-to-point broadcast reception capabilities (a is greater than or equal to 1) in an interval, when a = 1, if the Release-15 (R-15) mechanism is used,There may not be any interval that can transmit a PDCCH indicating SPS Resource Release (since R-15 requires that the PDCCH indicating SPS Resource Release and the PDSCH cannot be transmitted in the same interval when only a single-interval point-to-point broadcast PDSCH reception resource is supported), resulting in failure to transmit the PDCCH indicating SPS Resource Release; for the case where a is greater than 1 (e.g., a = 2, 4, 7), R-15 has no solution because R-15 does not occur in an interval where greater than 1 SPS PDSCH and a PDCCH indicating SPS Resource Release exist simultaneously, and R-16 has no position to perform HARQ-ACK feedback for the PDCCH indicating SPS Resource Release if only the HARQ-ACK feedback positions corresponding to PDSCH transmission opportunities are reserved for this interval.If one or more PDCCHs indicating SPS resource release are received again within this interval when an SPS PDSCH transmission already exists within this interval, for the semi-persistent HARQ-ACK codebook feedback mode, there is no position to perform. Petition 870220092961, dated 10 / 10 / 2022, page 6 / 332 3 / 80 HARQ-ACK feedback to the PDCCH indicating SPS resource release; alternatively, if the number of SPS in a range does not exceed a, but the number C of downlink transmission opportunities determined according to the TDRA table in the range is less than the sum of the number of SPS and PDCCH indicating SPS resource release, HARQ-ACK feedback to the PDCCH indicating SPS resource release cannot be supported, because the actual HARQ-ACK position only supports a maximum of C downlink transmissions.

[0006] Therefore, in R-16, there is no clear method for feedback of HARQ-ACK on a PDCCH indicating SPS resource release for a terminal that only supports a maximum capacity of a (a is greater than 1) of PDSCH point-to-point broadcast reception in a range, and HARQ-ACK feedback cannot currently be performed on a PDCCH indicating SPS resource release when the sum of the number of SPS in a range and the number of PDCCHs indicating SPS resource release exceeds either A or the number of downlink transmission opportunities C in the range.

[00180] To make the technical problems, technical solutions and advantages to be solved by the present disclosure clearer, the following detailed description is created with reference to the attached drawings and specific embodiments.

[00181] The disclosure modality provides a feedback method of HARQ-ACK, which is used to map the HARQ-ACK feedback of a PDCCH (Physical Downlink Control Channel) indicating SPS resource release according to a reference time-domain resource when the PDCCH indicating SPS resource release is received within an interval to receive the PDSCH (Physical Downlink Shared Channel) transmission of semi-persistent scheduling SPS, in order to solve the problem that the HARQ-ACK feedback mode of the PDCCH indicating SPS resource release is ambiguous when related technologies support a plurality of SPS configurations.

[00182] In order to clearly illustrate the HARQ-ACK feedback method according to the embodiment of the present disclosure, an application scenario of the HARQ-ACK feedback method is described first below.

[00183] Flexible timing relationships are supported in current wireless communication systems. For a Physical Downlink Shared Channel (PDSCH), a Physical Downlink Control Channel (PDCCH) carrying scheduling information indicates a scheduling timing relationship (K0) between the PDSCH and the PDCCH and a relationship of Petition 870220092961, dated 10 / 10 / 2022, page 27 / 332 24 / 80 feedback timing (HARQ-ACK timing, K1) between the PDSCH and its corresponding HARQ-ACK. Specifically, the time-domain resource allocation indication field in Downlink Control Information (DCI) format used by the PDCCH indicates a K0 interval offset between the interval where the PDSCH is located and the interval where the DCI is located; the PDSCH-to-HARQ-ACK feedback timing indication field in DCI format indicates the number of K1 intervals from the end of the PDSCH to the beginning of the HARQ-ACK, i.e., the PDSCH transmitted in interval n performs HARQ-ACK transmission in interval n + K1, as shown in Figure 1 below. The complete set of K1 is {0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15} and is normally configured for the terminal with a maximum of 8 values.

[00184] Semi-static and dynamic HARQ-ACK codebook generation modes are also supported in the current communication system. The HARQ-ACK codebook is a HARQ-ACK feedback sequence generated for downlink transmission (which includes a PDSCH and a PDCCH indicating downlink SPS resource release, and the PDCCH indicating downlink SPS resource release may also be referred to as an SPS release PDCCH or an SPS release PDSCH) that performs HARQ-ACK feedback at the same time domain or uplink channel position.

[00185] The semi-static HARQ-ACK codebook is a set of downlink transmission opportunities corresponding to an uplink interval or subinterval determined according to a set K1 and a downlink Time Domain Resource Allocation information table (i.e., Time Domain Resource Allocation (TDRA) table or set corresponding to (in the active BWP of) Petition 870220092961, dated 10 / 10 / 2022, page 28 / 332 25 / 80 each downlink carrier, where each row in the table represents a scheduling condition in the Time Domain and can provide information such as a starting symbol, the number of symbols, a scheduling time sequence (i.e., K0), a semistatic uplink-downlink relationship (in a configured condition), and the number of times PDSCH is repeatedly transmitted (in a configured condition).

[00186] The downlink transmission opportunity set is semistatic and does not change with specific scheduling conditions, so that, according to the configured semistatic parameters, the defined downlink transmission opportunity MA·c on each downlink carrier that corresponds to an uplink interval or subinterval on the carrier to transmit the PUCCH can be determined uniquely and according to the MA·c of each carrier, the sequence of HARQ-ACK information transmitted through the same PUCCH in the uplink interval or subinterval on the carrier to transmit the PUCCH is determined, where the sequence length is the number of elements in the MA·c and the number of HARQ-ACK feedback bits corresponding to each transmission opportunity (element), and the sequencing of the HARQ-ACK feedback information is sequenced according to the position of the PDSCH in the sequence length.

[00187] Specifically, taking as an example the case of PUCCH based on interval transmission, for each carrier c, according to each value of K1 in the K1 set, a set of intervals corresponding to the interval n for HARQ-ACK feedback is determined; in each interval in the set of intervals, which determines an opportunity for downlink transmission corresponding to each interval according to the possibility of the terminal supporting receiving more than one point-to-point PDSCH broadcast in the interval; if the terminal supports the Petition 870220092961, dated 10 / 10 / 2022, page 29 / 332 26 / 80 receiving more than one point-to-point PDSCH broadcast in an interval, further based on multiple time domain positions in the TDRA table (a time domain position can be referred to as a Start and Length Indicator Value (SLIV), which expresses a combination of a Start symbol and the number of transmission symbols), the SLIVs are divided into several groups according to a predetermined rule based on a mutual overlap condition, and each group can be considered as having a downlink transmission (this is because overlapping SLIVs are only used to provide scheduling flexibility, but only one SLIV can be selected from the overlapping SLIVs to be used in the actual schedule and two PDSCHs cannot be scheduled to use the overlapping SLIVs at the same time), in order to determine the maximum number of downlink transmissions in an interval.

[00188] If the terminal cannot support receiving more than one point-to-point broadcast of PDSCH in an interval, determine that an interval corresponds to 1 opportunity for downlink transmission; if a semi-static uplink and downlink interval structure is configured, if an uplink symbol exists in a symbol set contained in a SLIV in an interval, and due to the existence of uplink and downlink resource conflict, downlink transmission does not actually occur, the SLIV can be removed from the SLIV set and only when the symbol determined according to the downlink timedomain resource allocation information in an interval is a downlink or flexible symbol, downlink transmission can exist in the interval and, if all SLIVs in an interval are removed, the interval will be removed; obtain the matching MA·c of each carrier according to the above method and determine the Petition 870220092961, dated 10 / 10 / 2022, p. 30 / 332 27 / 80 HARQ-ACK information sequence of carrier c in interval n according to MA·c, where the HARQ-ACK information sequence includes the sequence size and the specific HARQ-ACK content and sequence; and finally, cascade the HARQ-ACK information sequences corresponding to each carrier together, according to the sequence of carrier numbers from small to large to form a HARQ-ACK codebook transmitted by the PUCCH in an ascending link interval or a carrier subinterval to transmit the PUCCH through the terminal.

[00189] Based on the HARQ-ACK codebook determination rule, when SPS PDSCH transmission is configured, because HARQ-ACK feedback needs to be loaded into PDCCH to indicate SPS resource release, the aboveMA·c set includes PDCCH to indicate SPS resource release, and therefore the HARQ-ACK codebook includes PDCCH HARQ-ACK to indicate SPS resource release.

[00190] Based on the rule, when there are PDSCH transmissions of SPS corresponding to a plurality of SPS configurations on a carrier, there may be at least one PDSCH transmission of SPS corresponding to an SPS configuration in each range and for a terminal that supports only A (A is greater than 1) point-to-point PDSCH broadcast reception capabilities in a range, it is still necessary to make explicit how to perform HARQ-ACK feedback on a PDCCH that indicates SPS resource release.

[00191] As shown in Figure 2, the feedback method of HARQ-ACK, according to an embodiment of the present disclosure, is applied to a terminal and includes:

[00192] S210: If a Physical Downlink Control Channel (PDCCH) indicates a Semi-Persistent Scheduling (SPS) resource release, that is Petition 870220092961, dated 10 / 10 / 2022, page 31 / 332 28 / 80 received within an interval to receive a Physical Downlink Shared Channel (PDSCH) transmission from SPS, map a HARQ-ACK feedback from the PDCCH indicating the release of SPS resources, to a feedback position determined according to a reference time-domain resource in a HARQ-ACK feedback sequence;

[00193] S220: transmit the HARQ-ACK feedback sequence which includes the PDCCH HARQ-ACK feedback indicating the release of the SPS resource.

[00194] According to the HARQ-ACK feedback method in the embodiment of the present disclosure, for a terminal that adopts the semi-static transmission of the HARQ-ACK codebook and supports receiving A (A is greater than 1) of point-to-point broadcast PDSCHs at most in an interval, wherein the HARQ-ACK feedback of the PDCCH indicates that the release of the SPS resource is mapped to a determined feedback position according to a reference time-domain resource in a HARQ-ACK feedback sequence, thus solving the technique in the related technique that the HARQ-ACK feedback mode of the PDCCH indicating the release of the SPS resource is ambiguous when multiple SPS configurations are supported.

[00195] It should be noted that the SPS PDSCH required to be received here may not include all activated or configured SPS, but the remaining SPS PDSCH is filtered through a specific rule, i.e., the SPS PDSCH required to be received in the manner of this disclosure is not an SPS that is determined not to need to receive or need HARQ-ACK feedback according to a specific rule, but is an SPS PDSCH that is determined to be received and needs to perform HARQ-ACK feedback according to a specific rule. For example, if multiple SPS PDSCHs are configured within a range and the multiple SPS PDSCHs overlap in Petition 870220092961, dated 10 / 10 / 2022, p. 32 / 332 29 / 80 time-domain resources, the SPS to be received is the SPS PDSCH with the lowest SPS configuration index among the overlapping SPS PDSCHs determined according to the overlap rule, instead of all SPS PDSCHs being counted; for another example, if the maximum N1 of point-to-point broadcast PDSCHs is supported for reception in an interval, and N2 is greater than N1 of SPS PDSCHs in the current interval, no SPS PDSCHs greater than N1 are selected from N2 of SPS PDSCHs in order of small to large SPS configuration indices as SPS PDSCHs to be received;For another example, a range includes N2 SPS PDSCHs, and a symbol set in which the N3 SPS PDSCHs are located includes uplink symbols configured by an upper layer (i.e., there is a collision with the uplink symbols), so the SPS PDSCHs that collide with the uplink symbols are not SPS PDSCHs that need to be received, that is, the SPS PDSCHs after the colliding N3 SPS PDSCHs are removed from the N2 SPS PDSCHs are the SPS PDSCHs that need to be received. Of course, the above description of the SPS PDSCH to be received is an example, and the SPS PDSCH transmitted in this range may be configured without the above limitation.

[00196] The HARQ-ACK feedback sequence, that is, the HARQ-ACK codebook mentioned above, can be determined in the manner described above and will not be described in this document.

[00197] It should be noted that, in step S210, in the embodiment of the present disclosure, the method further includes: mapping the PDCCH HARQ-ACK feedback indicating the release of SPS resource to the determined feedback position according to the reference time-domain resource in the HARQ-ACK feedback sequence when a first condition, which is at least one of the following conditions, is met: Petition 870220092961, dated 10 / 10 / 2022, page 33 / 332 30 / 80

[00198] a sum of a B1 quantity of SPS PDSCH to be received and a B2 quantity of PDCCH indicating that the SPS resource release does not exceed a first value; wherein the first value is a maximum point-to-point diffusion quantity of PDSCHs capable of being received within a range;

[00199] a sum of a B1 quantity of SPS PDSCH to be received and a B2 quantity of PDCCH indicating that the SPS resource release does not exceed a second value; where the second value is a quantity of downlink transmission opportunities in an interval;

[00200] where B1 and B2 are both positive integers greater than or equal to 1.

[00201] Based on the above modality, when it is determined that at least one of the first conditions is satisfied, map the HARQ-ACK feedback from a PDCCH indicating SPS resource release to a feedback position in a HARQ-ACK feedback sequence determined according to a reference time-domain resource; otherwise, the HARQ-ACK is not fed back to the PDCCH indicating the SPS resource release; Alternatively, the scheduling is considered erroneous, that is, the terminal does not expect to receive B2 from PDCCHs indicating an SPS resource release in an interval containing B1 transmissions from SPS PDSCH that need to be received, and the sum of B1 and B2 exceeds said first value and / or the terminal does not expect to receive B2 from PDCCHs indicating an SPS resource release in an interval containing B1 transmissions from SPS PDSCH that need to be received, and the sum of B1 and B2 exceeds said second value.Obviously, the above determination may not be realized, and when there is an SPS PDSCH and a PDCCH indicating SPS resource release within an interval, the HARQ-ACK feedback from the PDCCH indicating SPS resource release is always mapped. Petition 870220092961, dated 10 / 10 / 2022, page 34 / 332 31 / 80 for a feedback position determined according to the reference time domain feature in the HARQ-ACK feedback sequence.

[00202] It should be noted that the sizes of the second values ​​corresponding to different intervals may be the same or different; this is because, although different intervals correspond to the same TDRA table for determining the number of downlink transmission opportunities, different intervals may have different interval structures and the sets of SLIVs available in the TDRA tables obtained in different interval structures may be different.

[00203] Furthermore, it should be noted that, in the embodiment of the present disclosure, the downlink transmission opportunity mentioned is a candidate PDSCH transmission opportunity. The number of downlink transmission opportunities represents the maximum quantity (i.e., the second number) of PDSCHs that can be transmitted by TDM in an interval and is limited by a predetermined TDRA table, which may include multiple rows, each row may provide a time domain resource information (SLIV, which includes at least one initial symbol and transmission length information), an SLIV may determine a PDSCH transmission location, but since the TDRA table is used to support a base station to flexibly select which symbols in an interval and transmit a PDSCH in how many symbol lengths, there may be an overlap between the SLIVs provided by each row in the TDRA table, for example,The SLIV provided by the first row indicates that the initial symbol is symbol 1, the transmission symbol length is 7 symbols; the SLIV provided by the second row indicates that the initial symbol is symbol 2, the transmission length is 7 symbols; the SLIV provided by the third row indicates that the initial symbol is symbol 3, the transmission length is 5 symbols, etc. And obviously, because the 3 SLIVs are mutually overlapping, the base station selects only one of the 3 SLIVs to transmit the PDSCH during the actual scheduling, and when one, Petition 870220092961, dated 10 / 10 / 2022, page 35 / 332 32 / 80 of the SLIVs is selected to transmit the PDSCH; the other overlapping SLIVs are not used to transmit the PDSCH.

[00204] It is clear that the TDRA table can also contain SLIVs that do not overlap and, therefore, based on the TDRA table, according to the relationship between the SLIVs, it can be divided into a plurality of SLIV groups according to a predetermined rule, there can be one SLIV in each group used for PDSCH transmission, the number of SLIV groups thus determines the number of candidate PDSCH transmission opportunities in a range, and before the SLIV group partitioning described above, for each SLIV, an unusable SLIV in the TDRA table can be removed according to a semi-statically configured range structure (if any) in the current range, where the unusable SLIV is an uplink symbol in which at least one symbol is semi-statically configured in a symbol set indicated by the SLIV, since downlink transmissions cannot be transmitted on uplink symbols,This SLIV is not actually used for scheduling PDSCH transmissions; if an SPS PDSCH transmission is allocated, this SPS PDSCH will also not be transmitted. Because the semi-static range structure of each range may be different, the aforementioned actions of removing unavailable SLIVs are performed separately for each range, and SLIVs removed for different ranges may be different, so the number of downlink transmission opportunities that can be supported in different ranges may also be different.

[00205] Specifically, if the terminal supports reception of more than one PDSCH point-to-point broadcast within a range, SLIV grouping can be performed according to a predetermined rule based on the SLIV defined in the TDRA table, which finds the SLIV with the earliest first end position, based on that SLIV, which finds all SLIVs whose start positions are earlier than the end position. Petition 870220092961, dated 10 / 10 / 2022, page 36 / 332 33 / 80 of this SLIV, which treats these SLIVs as a group, which corresponds to a possible downlink transmission opportunity, and then remove these SLIVs from the set of SLIVs, repeating the above steps for the remaining SLIVs until all SLIVs contained in the TDRA table are processed to obtain multiple downlink transmission opportunities, as shown in Figure 3, which results in a group of elements a / B / C, which corresponds to a downlink transmission opportunity, element D / E is a group, which corresponds to a downlink transmission opportunity, a total of 2 downlink transmission opportunities are obtained, i.e., there can be 2 PDSCH transmissions in the interval that are not overlapping.

[00206] Certainly, the actual transmission can be two PDSCHs or it can be just one PDSCH, specifically depending on the SLIV assigned to the PDSCH, for example, if a PDSCH is assigned to use SLIV-C, then, since this SLIV overrides all other SLIVs, all other SLIVs are unavailable, at this moment there is only one PDSCH, for example, if one PDSCH is assigned to use SLIV-B and another PDSCH is assigned to use SLIV-D, then these two SLIVs do not overlap and both PDSCHs can transmit;Because the semi-static HARQ-ACK needs to ensure that the stability of the feedback bit does not change along with the scheduling condition, when the semi-static HARQ-ACK is transmitted, the HARQ-ACK feedback position is reserved for each interval according to the maximum number of downlink transmission opportunities. If a plurality of PDSCHs actually exists, the HARQ-ACKs of the PDSCHs are mapped to the corresponding positions according to the corresponding SLIVs, and NACK is generated as busy if the HARQ-ACK position received by the corresponding PDSCH does not exist.

[00207] In the example in Figure 3, for this interval, it is equivalent to two HARQ-ACK feedback positions being reserved in the sequence of Petition 870220092961, dated 10 / 10 / 2022, pp. 37 / 332 34 / 80 semi-static HARQ-ACK feedback, if there is actually only one PDSCH using an SLIV in aE in this interval, it is possible to know, according to whether the SLIV used by this PDSCH belongs to the first set or the second set of SLIVs, to which of the 2 HARQ-ACK positions corresponding to this interval, the HARQ-ACK of this PDSCH is mapped, for example, this PDSCH uses an SLIV in a a\B\C, which is mapped to the first HARQ-ACK position, if an SLIV is used in D\E, which is mapped to the second HARQ-ACK position; The number of HARQ-ACK bits in each HARQ-ACK position is not necessarily 1 bit, and depends on the PDSCH transmission configuration on the current carrier; for example, 2 TB transmission modes are configured and HARQ-ACK spatial combination is not configured (spatial combination, i.e., logical, is performed between HARQ-ACKs of two TBs to achieve 1-bit HARQ-ACK operation).A HARQ-ACK position is a 2-bit feedback and corresponds to each Transport Block (TB). If the 1 TB transmission mode is configured, or the 2 TB transmission modes are configured, and the HARQ-ACK spatial combination is configured, a HARQ-ACK is a 1-bit feedback. For example, if CBG-based transmission and feedback are configured, the number of HARQ-ACK feedback bits needs to be determined by combining the number of Code Block groups (CBGs) into which a TB is divided; each CBG for each TB corresponds to a 1-bit feedback.

[00208] According to the method for determining the HARQ-ACK feedback position in the feedback sequence based on the SLIV group and the number of downlink transmission opportunities obtained by the semi-static codebook based on the SLIV group, when there is a PDCCH indicating SPS resource release in an interval, the PDCCH also needs to perform HARQ-ACK feedback, if the HARQ-ACK position of the PDCCH in the HARQ-ACK feedback sequence needs to be obtained, an SLIV reference is Petition 870220092961, dated 10 / 10 / 2022, pp. 38 / 332 35 / 80 required, the SLIV that is selected as the reference comes from the TDRA table, the position of HARQ-ACK in the HARQ-ACK feedback sequence is determined based on all SLIVs available in the TDRA table, obviously, the SLIV reference corresponding to PDCCH also includes the SLIV reference corresponding to PDCCH, and therefore, PDCCH can find the corresponding feedback position in the HARQ-ACK feedback sequence according to the SLIV reference.

[00209] However, when there are different reference SLIV definitions, the following cases may occur, for example, if the reference SLIV is indicated by the PDCCH itself, the base station can ensure that an SLIV that does not collide with the SLIV used in the current range is selected when selecting the SLIV, so that the HARQ-ACK feedback position of the PDCCH is determined according to the SLIV and does not collide with HARQ-ACKs from other existing transmissions (e.g., PDSCH from SPS in the range); It is clear that if the SPS PDSCH in the interval has already reached the number of downlink transmission opportunities for the interval, this means that determining the HARQ-ACK feedback position of the PDCCH referring to any SLIV will conflict with the HARQ-ACK feedback position of an existing SPS PDSCH, because the reference SLIV definitely belongs to a specific SLIV group, and an SLIV already exists in each SLIV group and is in use.Therefore, any SLIV in the group is used to obtain the same HARQ-ACK feedback position, so there is a feedback position conflict. At this point, if the PDCCH's HARQ-ACK is to be fed back, under the condition that the HARQ-ACK feedback position reserved for the interval in the HARQ-ACK feedback sequence is not increased, only the HARQ-ACK feedback position corresponding to a given SPS PDSCH in the HARQ-ACK feedback position can be substituted for HARQ-ACK transmission to the PDCCH, the HARQ-ACK for this. Petition 870220092961, dated 10 / 10 / 2022, page 39 / 332 36 / 80 A replaced SPS PDSCH cannot be transmitted. If the alternative situation must be avoided, the base station is obliged to limit, in the scheduling, the PDCCH that indicates the release of SPS resources in the interval that already contains the transmission of SPS PDSCH with the number of downlink transmission opportunities not to be transmitted, because if the PDCCH is transmitted, the HARQ-ACK feedback position is insufficient, so the PDCCH needs to occupy the HARQ-ACK feedback positions of other SPS PDSCHs for feedback.

[00210] For another example, if the reference SLIV of a PDCCH is the SLIV of an SPS PDSCH released by the PDCCH, then it depends on the possibility of this referenced SPS PDSCH also being transmitted within the interval of this PDCCH transmission:

[00211] 1) Otherwise, such a collision may exist when borrowing SPS PDSCH SLIVs transmitted in other intervals within a PDCCH transmission interval, because even if the SPS PDSCH in the interval where the PDCCH is transmitted corresponds to a different SPS configuration than the SPS PDSCH released by the PDCCH, since the two are transmitted in different intervals, there is no interaction between the HARQ-ACK feedback even if the SLIVs are completely identical or overlap, because the HARQ-ACK feedback positions are reserved separately for each interval, so there may be a collision with the HARQ-ACK feedback positions of other SPS PDSCHs in the interval when determining the HARQ-ACK feedback position of the PDCCH using the reference SLIVs, and resolving the collision may also employ one of the methods above,How to transmit PDCCH HARQ-ACK while occupying PDSCH HARQ-ACK feedback positions that collided with PDCCH reference SLIVs, the PDSCH HARQ-ACK from SPS that collides with the SLIV reference cannot be transmitted, or the base station avoids scheduling, i.e., selects a collision-free interval to transmit the PDCCH, or, Petition 870220092961, dated 10 / 10 / 2022, page 40 / 332 37 / 80, that is, the terminal side does not expect to transmit the PDCCH in the interval containing the SPS PDSCH that collides with the PDCCH SLIV reference; if the reference SLIV does not conflict with the SPS PDSCH SLIV in the current interval, determine a HARQ-ACK feedback position according to the reference SLIV and feed back the PDCCH HARQ-ACK based on not influencing the SPS PDSCH HARQ-ACK feedback in the current interval;

[00212] 2) If so, when the HARQ-ACK feedback position is determined by the SLIV to transmit the PDCCH HARQ-ACK, the HARQ-ACK feedback from another SPS PDSCH (possibly including the SPS PDSCH that is not indicated to be released by the PDCCH, i.e., the SPS PDCCH in the SPS PDSCHs indicated to be released by the PDCCH, other than the PDCCH mentioned above) in the interval is not influenced when the PDCCH HARQ-ACK is transmitted using the HARQ-ACK feedback position, and the HARQ-ACK feedback position corresponding to the SLIV that occupies the released SPS PDSCH is also reasonable because the SPS PDSCH is released and the HARQ-ACK feedback position of the SPS PDSCH can be free to be used for HARQ-ACK transmission from the PDCCH.

[00213] Optionally, the method also includes: mapping the feedback of HARQ-ACK of PDCCH indicating the release of SPS resource to the determined feedback position according to the reference time domain resource in the HARQ-ACK feedback sequence when a second condition, which is at least one of the following conditions, is met:

[00214] a first second condition is one of the following conditions:

[00215] the SPS PDSCH indicated to be released by the PDCCH indicates that the SPS resource release does not include any of the SPS PDSCHs to be received;

[00216] the SPS PDSCH to be received does not include a target SPS PDSCH; the The target SPS PDSCH is the SPS PDSCH with an SPS configuration index. Petition 870220092961, dated 10 / 10 / 2022, page 41 / 332 38 / 80 minimum or maximum in the SPS PDSCH indicated to be released by the PDCCH that indicates the release of the SPS resource;

[00217] the SPS PDSCH to be received includes a portion of the SPS PDSCHs indicated to be released by the PDCCH indicating the release of SPS resources;

[00218] a second condition is:

[00219] the SPS PDSCH to be received and the PDCCH indicating the release of SPS resources have the same priority;

[00220] a third second condition is:

[00221] the PDCCH indicating the release of SPS resources and the SPS PDSCH to be received perform a HARQ-ACK transmission in the same interval or subinterval;

[00222] a fourth second condition is:

[00223] the SPS PDSCH to be received and the PDCCH indicating the release of SPS resources are transmitted on the same carrier;

[00224] a fifth twelfth condition is:

[00225] a maximum amount of point-to-point PDSCH broadcast capable of being received by the terminal in an interval is greater than 1 or equal to 1;

[00226] a sixth twelfth condition is:

[00227] the terminal configures a hybrid semi-static automatic repeat request confirmation information transmission mode.

[00228] According to the HARQ-ACK feedback method, when at least one second condition is met, the HARQ-ACK feedback from a PDCCH indicating SPS resource release is mapped to a feedback position determined according to a reference time-domain resource in a HARQ-ACK feedback sequence; otherwise, HARQ-ACK for PDCCH indicating SPS resource release may not be transmitted in the manner presented in this disclosure and certainly does not exclude that Petition 870220092961, dated 10 / 10 / 2022, page 42 / 332 39 / 80 HARQ-ACK for PDCCH, which indicates SPS resource release, can be transmitted in the same manner as presented in this disclosure.

[00229] Optionally, in the first second condition:

[00230] when the number of received PDCCHs indicating the release of SPS resources is B2, the SPS B1 PDSCHs are not included in the SPS B2 PDSCHs indicated by the PDCCH indicating the release of SPS resources, or the SPS B2 PDSCHs indicated by the PDCCH indicating the release of SPS resources are not included in the SPS B1 PDSCHs;

[00231] the target SPS PDSCH is the SPS PDSCH with the minimum or maximum SPS configuration index in the SPS PDSCH indicated to be released by the PDCCH indicating the release of the SPS resource, namely, SPS PDSCHs B1 must be received by the interval and when the number of PDCCHs received indicating that the release of the SPS resource is B2, the SPS PDSCHs B1 do not contain the SPS PDSCH with the minimum or maximum index in the SPS PDSCH indicated to be released by each PDCCH in the PDCCHs B2 to indicate the release of the SPS resource.

[00232] In one mode, if there are multiple PDCCHs indicating SPS resource release, the SPS PDSCH with the minimum index or maximum index is the SPS PDSCH with the minimum SPS configuration index in the SPS PDCCHs indicated to be released by each PDCCH.

[00233] The SPS PDSCHs to be received include the partial SPS PDSCHs indicated by the PDCCH indicating the release of SPS resources, i.e., SPS PDSCHs B1 need to be received for a range and when the received PDCCH indicating the release of SPS resources is B2, the SPS PDSCHs B1 include the partial SPS PDSCHs indicated by each PDCCH of the B2 PDCCHs indicating the release of SPS resources, for example, include at least one SPS PDSCH that does not indicate the lowest index among the SPS PDSCHs indicating the release. Petition 870220092961, dated 10 / 10 / 2022, page 43 / 332 40 / 80

[00234] It should be noted that, in one embodiment, in the absence of the limitation of the first and second conditions described above, it is considered that, in any case, provided that a PDCCH indicating SPS resource release is received within an interval that includes SPS PDSCH transmission, HARQ-ACK feedback from the PDCCH indicating SPS resource release is always mapped to a feedback position in a HARQ-ACK feedback sequence determined according to a reference time-domain resource, so as to transmit HARQ-ACK feedback from the PDCCH indicating SPS resource release.

[00235] In a second condition, when the PDCCH indicating SPS resource release needs to be received and the PDCCH indicating SPS resource release has the same priority, i.e., SPS B1 PDSCHs need to be received within an interval, and the received PDCCH indicating SPS resource release has B2, B2 PDCCHs indicating SPS resource release have the same priority as SPS B1 PDSCHs (i.e., the HARQ-ACK codebook corresponding to the PDCCH indicating SPS resource release has the same priority as the HARQ-ACK codebook corresponding to the SPS PDSCH, wherein the HARQ-ACK codebook corresponding to the PDCCH indicating SPS resource release has the same priority as the HARQ-ACK codebook corresponding to the SPS PDSCH released by the PDCCH indicating SPS resource release).Based on the second condition, when PDCCHs B2 indicating SPS resource release have the same priority as PDSCH B1, map the HARQ-ACK feedback of the PDCCHs indicating SPS resource release to a feedback position determined according to the reference time domain resource in a HARQ-ACK feedback sequence.

[00236] In a third second condition, the PDCCH indicating the release of SPS resources and the SPS PDSCH to be received perform the transmission of Petition 870220092961, dated 10 / 10 / 2022, page 44 / 332 41 / 80 HARQ-ACK in the same interval or subinterval, i.e., when PDSCHs from SPS B1 need to be received for an interval and when the received PDCCH indicating SPS resource release is B2, PDCCHs B2 indicating SPS resource release and PDSCHs from SPS B1 perform HARQ-ACK transmission in the same interval or subinterval; i.e., when PDCCHs B2 indicating SPS resource release and PDSCH from SP SB1 perform HARQ-ACK transmission in the same interval or subinterval (i.e., HARQ-ACK transmission is performed in the same PUCCH, i.e., the PDCCH and PDSCH from SPS correspond to the same K1 value), the HARQ-ACK feedback from the PDCCHs indicating SPS resource release is mapped to a determined feedback position according to the reference time domain resource in a HARQ-ACK feedback sequence.

[00237] Additionally, the method includes:

[00238] determine the reference time domain feature as one of:

[00239] a time-domain resource indicated by PDCCH that indicates the release of SPS resources;

[00240] a time-domain resource corresponding to the SPS PDSCH indicated to be released by the PDCCH indicating the release of the SPS resource.

[00241] Optionally, when the reference time-domain resource is the time-domain resource corresponding to the SPS PDSCH indicated to be released by the PDCCH indicating SPS resource release,

[00242] when the PDCCH indicating the release of an SPS resource indicates the release of an SPS PDSCH, the reference time-domain resource is the time-domain resource corresponding to the released SPS PDSCH;

[00243] when the PDCCH indicating the release of an SPS resource indicates the joint release of a plurality of SPS PDSCHs, the reference time-domain resource is a time-domain resource corresponding to a PDSCH Petition 870220092961, dated 10 / 10 / 2022, page 45 / 332 42 / 80 of SPS with a minimum or maximum SPS configuration index within the plurality of SPS PDSCHs released together, or the reference timedomain resource is a timedomain resource corresponding to an SPS PDSCH transmitted in the interval with a minimum or maximum SPS configuration index within the plurality of SPS PDSCHs released together.

[00244] In one embodiment of the present revelation, the method also includes:

[00245] the reference time domain resource is not overlapping with the SPS PDSCH time domain resource to be received or does not correspond to the index of the same downlink transmission opportunity (i.e., after SLIV grouping is performed on the SLIVs in the TDRA table according to the predetermined rule, a downlink transmission opportunity or a downlink transmission opportunity corresponding to each group of SLIVs is obtained, so as to obtain a set of multiple downlink transmission opportunities corresponding to an interval, each downlink transmission opportunity in the set has its own index, which indicates the downlink transmission opportunity number one in the interval,and the downlink transmission opportunity index is the index position in the HARQ-ACK position reserved for the downlink transmission opportunity defined in the interval in the HARQ-ACK feedback sequence, corresponding to the downlink transmission opportunity index); or

[00246] when the reference timedomain resource overlaps with the timedomain resource of at least one SPS PDSCH in the SPS PDSCH to be received or corresponds to the same downlink transmission opportunity index, which does not perform a HARQ-ACK feedback to the SPS PDSCH that overlaps with the reference timedomain resource or corresponds to the same downlink transmission opportunity index in the SPS PDSCH to be received. Petition 870220092961, dated 10 / 10 / 2022, page 46 / 332 43 / 80

[00247] Optionally, do not perform HARQ-ACK feedback for the A PDSCH of SPS that overlaps with the reference timedomain resource or corresponds to the same downlink transmission opportunity index in the SPS PDSCH to be received, when the reference timedomain resource overlaps with the timedomain resource of at least one SPS PDSCH in the SPS PDSCH to be received or corresponds to the same downlink transmission opportunity index, also includes:

[00248] transmit the PDCCH indicating the release of the SPS resource, no later than a start symbol position or a end symbol position of the SPS PDSCH that overlaps with the reference time domain resource or matches the same downlink transmission opportunity index in the SPS PDSCH to be received in the interval.

[00249] It should be noted that the terminal does not expect the reference timedomain resource to overlap with the SPS PDSCH timedomain resource to be received or to match the index of the same downlink transmission opportunity (i.e., the candidate PDSCH transmission opportunity), where matching the same index means that the HARQ-ACK mapping is performed by matching the same HARQ-ACK feedback position in the HARQ-ACK feedback sequence.

[00250] Specifically, when the reference timedomain resources do not overlap with the timedomain resources of the SPS B1 PDSCHs or do not match the index of the same transmission opportunity of the candidate PDSCH, or when the reference timedomain resources overlap with the timedomain resources of at least one SPS PDSCH of the SPS B1 PDSCHs or match the index of the same transmission opportunity of the candidate PDSCH, HARQ-ACK is not generated for the SPS PDSCH that overlaps with the resources of Petition 870220092961, dated 10 / 10 / 2022, page 47 / 332 44 / 80 reference time domain or corresponds to the index of the same opportunity for transmission of PDSCH candidate.

[00251] The above modality can be interpreted as meaning that a collision between the reference time-domain resource and the SPS PDSCH time-domain resource can be allowed (i.e., there is an overlap or an index corresponding to the same candidate PDSCH transmission opportunity), and at this time, the HARQ-ACK feedback position of the SPS PDSCH that collides with the reference time-domain resource needs to be occupied to transmit the PDCCH HARQ-ACK indicating the release of the SPS resource.

[00252] Specifically, for a terminal with a single point-to-point PDSCH fusion receive resource in a range, at most one SPS PDSCH to be received exists in the range, if a reference time-domain resource conflicts with the SPS PDSCH time-domain resource, HARQ-ACK is fed back only to a PDCCH indicating SPS resource release, namely, the SPS PDSCH HARQ-ACK is not fed back and the HARQ-ACK position is returned to the PDCCH indicating SPS resource release;

[00253] For a terminal with uniform PDSCH reception capability within a range, multiple SPS PDSCHs (or one SPS PDSCH) to be received may exist within the range. If the reference time-domain resource collides with the time-domain resource of at least one of the multiple SPS PDSCHs, HARQ-ACK feedback is performed on the SPS PDSCH with the collision of the reference time-domain resource, while HARQ-ACK feedback is performed on the SPS PDSCH with the collision of the reference time-domain resource (because the SPS PDSCH position is assigned to the PDSCH with the collision of the SPS resource released for HARQ-ACK feedback), but HARQ-ACK feedback can normally be performed on other PDSCHs. Petition 870220092961, dated 10 / 10 / 2022, page 48 / 332 45 / 80 of SPS without collision of the reference time-domain resource in multiple SPS PDSCHs.

[00254] Furthermore, in the modality of the present disclosure, in stage S210, the The SPS PDSCH to be received satisfies at least one of the following conditions:

[00255] the SPS PDSCH is an SPS PDSCH that needs HARQ-ACK;

[00256] The SPS PDSCH is determined not to collide with an uplink symbol according to a range structure configured by a high-layer signaling.

[00257] Furthermore, the reference time domain feature does not collide with the uplink symbol in the interval; uplink symbols are determined according to an interval structure configured by a high-layer signaling, if no high-layer signaling is configured, each symbol is considered a flexible symbol and an uplink or downlink transmission direction exists only when there is DCI programming or SFI indication.

[00258] In one embodiment, the SPS PDSCH to be received is a PDSCH of SPS that needs to be subjected to HARQ-ACK feedback, i.e., if there is a collision between SPS PDSCHs (for example, in case 1: in the same range of the same carrier, the time-domain resources of a plurality of SPS PDSCHs overlap; for example, in case 2: when the terminal can receive a maximum number of point-to-point broadcast PDSCHs in a range, if the number of SPS PDSCHs configured to be transmitted in the range exceeds that number, the selection of SPS PDSCHs needs to be performed according to a predetermined rule; for example, in case 3: cases 1 and 2 above exist simultaneously; for example, in case 4: there is an uplink symbol in a symbol set included in an SPS PDSCH and this SPS PDSCH cannot actually be transmitted), after collision resolution, it is determined that the SPS PDSCH of Petition 870220092961, dated 10 / 10 / 2022, p. 49 / 332 46 / 80 SPS to be received by the terminal and HARQ-ACK feedback (for example, in case 1, according to a selection rule among the overlapping SPS PDSCHs, select the SPS PDSCH with the minimum SPS configuration index in the overlap to receive and HARQ-ACK feedback, if a plurality of SPS PDSCHs overlap each other, remove other SPS PDSCHs overlapping the SPS PDSCH with the minimum index at the moment, according to a predefined rule and from small to large, according to the SPS configuration index, find the SPS PDSCH with the next minimum index, repeat the operation and, consequently, determine a plurality of different SPS PDSCHs one by one to receive and HARQ-ACK feedback without receiving other SPS PDSCHs and HARQ-ACK feedback;For another example, in case 2, according to a predetermined rule, no more than one SPS PDSCH can be selected to be received and its HARQ-ACK can be fed back in order from small to large SPS configuration indices, and no other SPS PDSCH is received and its HARQ-ACK does not need to be fed back; for another example, in case 3, the overlapping SPS is processed according to the rule in case 1 to obtain several non-overlapping SPS PDSCHs to be received, and then, among the SPS PDSCHs, the SPS PDSCHs that can be received are selected and the HARQ-ACK is fed back according to the limitation of the manner in case 2, and no HARQ-ACK is needed to be received nor fed back for other SPS PDSCHs; As another example, in case 4, it is determined that such a PDSCH from SPS does not need to be received or provide feedback (HARQ-ACK), in other words, the PDSCHs from SPS B1 are PDSCHs from SPS B1 that do not overlap in the time domain.

[00259] According to the HARQ-ACK feedback method in the embodiment of the present disclosure, for a terminal that adopts the semi-static transmission of the HARQ-ACK codebook and supports receiving A (A is greater than 1) of point-to-point broadcast PDSCHs at most in an interval, wherein the Petition 870220092961, dated 10 / 10 / 2022, page 50 / 332 47 / 80 PDCCH HARQ-ACK feedback indicates that the release of the SPS resource is mapped to a specific feedback position according to a reference time-domain resource in a HARQ-ACK feedback sequence, thus resolving the issue in the related technique that the PDCCH HARQ-ACK feedback mode indicating the release of the SPS resource is ambiguous when multiple SPS configurations are supported.

[00260] The embodiment of the present disclosure further provides a HARQ-ACK to HARQ-ACK feedback method, which is applied to a base station and, as shown in Figure 4, the method includes:

[00261] S410: If a Physical Downlink Control Channel (PDCCH) indicates a Semi-Persistent Scheduling (SPS) resource release, which is sent within an interval to send a Physical Downlink Shared Channel (PDSCH) transmission of SPS, determine that a HARQ-ACK feedback from the PDCCH indicating the SPS resource release is mapped to a feedback position determined according to a reference time-domain resource in a HARQ-ACK feedback sequence;

[00297] When the HARQ-ACK feedback method according to the embodiment of the present disclosure is applied to a base station, the above detailed description may be cited with reference to Figure 2 and Figure 3, and the details are not repeated here.

[00298] The following explains a specific process of the HARQ-ACK feedback method according to the embodiment of the present disclosure with reference to a specific implementation manner.

[00299] Assuming the terminal is configured with 5 settings of As shown in Figure 5, a semi-static HARQ-ACK codebook is adopted for SPS, where for simplicity it is assumed that the set K1 = {1, 2}, that the terminal's capacity to receive point-to-point PDSCH broadcasts in an interval is a maximum of a = 4, that is, feedback information corresponding to a maximum of 4 possible PDSCHs in a descending link interval of the HARQ-ACK codebook in a HARQ-ACK feedback interval, that the feedback information for each PDSCH is 1 bit, that the PDCCH indicating the release of the SPS resource is assumed to have the same priority as the HARQ-ACK feedback for each SPS, and that there are C = 4 opportunities to Petition 870220092961, dated 10 / 10 / 2022, p. 55 / 332 52 / 80 candidate PDSCH transmissions in intervals n, n+2, i.e., PDSCH transmissions in an interval for which a maximum of 4 TDMs can be scheduled, i.e., the 4 HARQ-ACK positions reserved in the HARQ-ACK codebook for which a corresponding PDSCH needs to be HARQ-ACKed back, are determined according to the TDRA table, which assumes that the feedback information of each PDSCH is 1 bit, each interval corresponds to 4-bit HARQ-ACK, it is determined from the TDRA table that there are C = 3 opportunities for candidate PDSCH transmissions in interval n+1.

[00300] Mode one, based on configuration parameters

[00301] Base station side: in range n, first mode: as there are already 4 SPS transmissions, if the base station wants to transmit a PDCCH indicating an SPS3 resource release, if K1=1 is set for the PDCCH, it cannot transmit in range n because there are already 4 PDSCH transmissions in range n, only C = 4 downlink transmission opportunities are supported, and it cannot support another PDCCH transmission indicating an SPS resource release because the HARQ-ACK is reserved for only 4 PDSCHs, and it cannot support another HARQ-ACK transmission of a PDCCH indicating an SPS resource release;Alternatively, the second mode: the base station can send a PDCCH indicating the release of SPS4, 5 in interval n, but indicate K1=2 for this PDCCH, that is, not allow the HARQ-ACK of this PDCCH and the HARQ-ACK of SPS1-4 in interval n to be transmitted in the same interval (the same PUCCH), then normal transmission can be performed, receiving the corresponding HARQ-ACK of SPS1, 2, 4, 5 in interval n+1 and the HARQ-ACK of the PDCCH indicating the release of SPS3 resources in interval n+2, respectively; alternatively, the third mode: the base station transmits the PDCCH in interval n indicating K1=1, and the HARQ-ACK of the PDCCH occupies the feedback position of the HARQ-ACK of an SPS from SPS1, 2, 4 and 5 in interval n; Petition 870220092961, dated 10 / 10 / 2022, p. 56 / 332 53 / 80 interval n for feedback, but the SPS HARQ-ACK cannot be fed back.

[00302] Terminal side: first, the PDCCH indicating the release of SPS is not expected to be received in interval n, because the total number of PDCCHs indicating the release of SPS resource and SPS1, 2, 4, 5 in interval n exceeds a = 4 and C = 4; alternatively, the second mode: the terminal receives the PDCCH in interval n and determines that the HARQ-ACK of the PDCCH is fed back in interval n+2, then the HARQ-ACK of SPS1, 2, 4 and 5 can be fed back in interval n+1 and the HARQ-ACK of the PDCCH indicating the release of SPS3 resource can be fed back in interval n+2 respectively, where the HARQ-ACK position of the PDCCH can be determined according to the SLIV of SPS3 in the released SPS3 by the HARQ-ACK position of the PDCCH;Alternatively, the third mode: the terminal receives the PDCCH in interval n, and determines that the HARQ-ACK of the PDCCH and the HARQ-ACK of SPS1, 2, 4 and 5 are fed back in interval n+1, the feedback position of the PDCCH HARQ-ACK in the HARQ-ACK codebook in interval n+1 is determined according to the SLIV of SPS3 indicated and released by the PDCCH, and the HARQ-ACK is mapped to the corresponding position, while the HARQ-ACK feedback is not performed in interval n+1 for the SPS (such as SPS 5) that is overlapped with the SLIV corresponding to the PDCCH or corresponds to the same downlink transmission opportunity index in SPS1, 2, 4 and 5, namely, the position is assigned to the PDCCH that indicates the release of the SPS resource.

[00303] Second mode;

[00304] Base station side: in an n+1 interval, first mode: as there are already 3 SPS transmissions, if the base station wants to transmit a PDCCH indicating SPS3 and / or 4 release, it cannot transmit in the n+1 interval if K1=1 is set for the PDCCH, because there are already 3 PDSCH transmissions in the n+1 interval, although the total number of PDCCH transmissions indicating resource release Petition 870220092961, dated 10 / 10 / 2022, page 57 / 332 54 / 80 of SPS does not exceed =4, but exceeds the number of downlink transmission opportunities C =3 that can be supported in the n+1 range, that is, only the HARQ-ACK positions corresponding to 3 downlink transmission opportunities are reserved in the HARQ-ACK codebook for the n+1 range, and if one more PDCCH indicating SPS resource release is added, there are no redundant feedback positions; Alternatively, the second mode: the base station can send a PDCCH indicating the release of SPS3, 4 in the n+1 interval, but indicate K1=2 for the PDCCH, that is, not allow the HARQ-ACK of the PDCCH and the HARQ-ACK of SPS1, 2, 5 in the n+1 interval to be transmitted in the same interval (the same PUCCH), and can normally transmit, receive corresponding HARQ-ACKs of SPS1, 2, 5 in the n+2 interval and receive HARQ-ACKs of PDCCH indicating the release of SPS3, 4 resources in the n+3 interval, respectively;Alternatively, the third mode: the base station transmits the PDCCH in the n+1 interval and indicates K1=1, and the HARQ-ACK of the PDCCH occupies the HARQ-ACK feedback position of an SPS1, 2, 5 in the n+1 interval for feedback, but the HARQ-ACK of the SPS cannot be fed back.

[00305] Terminal side, first mode: the PDCCH indicating the release of SPS3, 4 is not expected to be received in interval n+1 because the total number of PDCCHs indicating the release of SPS resources in interval n and the total number of SPS1, 2, 5 in interval n exceed C = 3; alternatively, the second mode: the terminal receives the PDCCH in interval n+1 and determines that the HARQ-ACK of the PDCCH is fed back in interval n+3, then the HARQ-ACK of SPS1, 2 and 5 can be fed back in interval n+2 and the HARQ-ACK of the PDCCH indicating the release of SPS3 and 4 resources can be fed back in interval n+3 respectively, where the HARQ-ACK position of the PDCCH can be determined according to the SLIV of SPS3 in the released SPS3 and 4 by the HARQ-ACK position of the PDCCH; alternatively, the third mode: the terminal receives the PDCCH in interval n+1, and Petition 870220092961, dated 10 / 10 / 2022, p. 58 / 332 55 / 80 determines that the HARQ-ACK from PDCCH and the HARQ-ACK from SPS1, 2, and 5 are fed back in the n+2 range; then, the feedback position of the PDCCH HARQ-ACK in the HARQ-ACK codebook in the n+2 range is determined according to the SPS3 SLIV in SPS3 and 4 that is indicated to be released by PDCCH; the HARQ-ACK is mapped to the corresponding position; and the HARQ-ACK feedback is not performed in the n+2 range for the SPS (such as SPS 5) that overlaps with the SLIV corresponding to PDCCH or corresponds to the same downlink transmission opportunity index in SPS1, 2, and 5, namely, the position is assigned to PDCCH that indicates the SPS resource to be released.

[00306] Third mode

[00307] The base station side may transmit a PDCCH that jointly indicates resource release of SPS3 and SPS4 (specifically, PDSCH corresponding to SPS configuration 3 and configuration 4) in the n+2 interval and indicate K1=1 of this PDCCH, assuming that K1=1 corresponds to each SPS PDSCH, i.e., 3 SPSs in the n+2 interval and a PDCCH indicating SPS resource release are both HARQ-ACK backed up in the n+3 interval, and SPS released by PDCCH indicating that SPS resource release is not included in 3 SPSs in the n+2 interval;At this moment, since an interval supports a maximum of HARQ-ACK feedback of a = 4 PDSCHs, and the interval n + 2 supports maximum transmission opportunities of C = 4 downlink, and at this moment, the SPS in the interval n + 2 and the PDCCH indicating SPS resource release do not always exceed a and C, HARQ-ACK feedback can be performed on the PDCCH indicating SPS resource release, so that the terminal maps HARQ-ACK from the PDCCH to HARQ-ACK positions in the HARQ-ACK codebook in the interval n+3 determined according to SPS3 indicating release and SPS3 of SLIVs in 4 indicating release and determines whether an SLIV corresponding to the PDCCH (the SLIV of SPS 3) overlaps with an SLIV corresponding to any of SPS1, 2 and 5 in the interval n+2 or; Petition 870220092961, dated 10 / 10 / 2022, p. 59 / 332 56 / 80 corresponds to an index of the same downlink transmission opportunity, and if it is determined that the HARQ-ACK of SPS1, 2, and 5 is mapped to SPS-ACK in the n+3 range according to 1, b 83, C, and C in the SPS codebook in the n+3 range, respectively, 2, 5, thus transmitting SPS1, SPS2, and SPS5 in the n+2 range and the HARQ-ACK of the PDCCH indicating the resource release of SPS3 and SPS4 in the same HARQ-ACK codebook in the n+3 range, and if the judgment is yes, perform HARQ-ACK feedback on the SPS (supposedly SPS 5) where SLIVs corresponding to the PDCCH are overlapping or correspond to the same downlink transmission opportunity index in SPS1, SPS2, and SPS5, where the HARQ-ACK feedback is not carried out, namely,The PDCCH HARQ-ACK indicating the mapped resource release at the position corresponding to the SLIVs or the downlink transmission opportunity index in the n+3 range HARQ-ACK codebook is not mapped, and the SPS5 HARQ-ACK cannot be mapped; and the base station side receives the HARQ-ACK codebook in the n+3 range in the same way, obtains the PDCCH indicating the SPS resource release and the SPS HARQ-ACK from the HARQ-ACK codebook, and determines whether the SPS resource release was successful and whether the SPS transmission is correct.

[00308] Example IV

[00309] In the third mode, the base station can also instruct K1=2 of PDCCH indicates resource release from SPS, i.e., performing HARQ-ACK feedback in the n+4 interval. Since the feedback is not performed in the same interval as SPS1, 2, 5 in the n+2 interval, it is not necessary to determine if the total number exceeds ae / or C. The feedback can be performed in the corresponding intervals; that is, the terminal feeds back the HARQ-ACKs of SPS1, 2, 5 in the n+1 interval in the n+3 interval and the HARQ-ACKs of PDCCH indicating SPS3, 4 resource release in the n+1 interval in the n+4 interval, respectively, where the position of Petition 870220092961, dated 10 / 10 / 2022, page 60 / 332 57 / 80 HARQ-ACK from PDCCH in HARQ-ACK is determined according to the SLIV of SPS3, 3 in SPS4 released by HARQ-ACK; SLIV conflict does not exist between the different feedback intervals; on the base station side, in the same way as above, the HARQ-ACKs of SPSs 1, 2 and 5 in interval n+1 are received in interval n+3, and the HARQ-ACKs of the PDCCHs indicating the release of SPS3 and 4 resources in interval n+1 are received in interval n+4, respectively, and the PDCCH indicating the release of SPS resources and the HARQ-ACKs of SPS are obtained from them, and it is determined whether the release was successful and whether the SPS transmission is correct.

[00310] Fifth mode

[00311] The base station may transmit a PDCCH that jointly indicates the release of SPS3 and SPS5 resources in the n+2 interval and that indicates K1=1 of this PDCCH, which assumes that K1=1 for each SPS PDSCH, i.e., 3 SPSs in the n+2 interval and a PDCCH indicating SPS resource release are both HARQ-ACK feedback in the n+3 interval and an SPS (SPS 5, i.e., the SPS is not the lowest index of the released SPSs) released by the PDCCH that indicates that the SPS resource release is included in 3 SPSs in the n+2 interval;Currently, since a range supports a maximum of HARQ-ACK feedback of a = 4 PDSCHs, and the range n + 2 supports maximum transmission opportunities of C = 4 downlink, and currently the SPS in the range n + 2 and the PDCCH indicating SPS resource release do not always exceed A and C, HARQ-ACK feedback can be performed on the PDCCH indicating SPS resource release, so that the terminal maps HARQ-ACK from the PDCCH to HARQ-ACK positions in the HARQ-ACK codebook in the range n+3 determined according to SPS3 of SLIVs in SPS3 and SPS5 indicated to be released, and determines whether an SLIV corresponding to the PDCCH (the SLIV of SPS 3) overlaps with an SLIV corresponding to any of SPS1, 2 and 5 in the range n+2 or corresponds to the same link transmission opportunity index. descendant, if applicable; Petition 870220092961, dated 10 / 10 / 2022, p. 61 / 332 58 / 80 determined that the HARQ-ACKs of SPS1, 2, and 5 are mapped to SPS-ACK in the n+3 range according to 1, SPS 83, PDSCH, and PDCCH in the HARQ-ACK codebook in the n+3 range, respectively, 2. 5, thus transmitting SPS1, SPS2, and SPS5 in the n+2 range and the HARQ-ACK of PDCCH indicating the resource release of SPS3 and SPS5 in the same HARQ-ACK codebook in the n+3 range, and if the judgment is yes, perform HARQ-ACK feedback on the SPS (supposedly SPS 2) where SLIVs corresponding to PDCCH are overlapped or correspond to the same downlink transmission opportunity index on SPS1, SPS2, and SPS5, where HARQ-ACK feedback is not performed, namely, HARQ-ACK The PDCCH indicating the resource release mapped to the position corresponding to the SLIVs or the downlink transmission opportunity index in the HARQ-ACK codebook of the n+3 range is not mapped, and HARQ-ACK of SPS2 cannot be mapped;The base station side receives the HARQ-ACK codebook in the n+3 interval in the same way, obtains the PDCCH indicating the release of the SPS resource and the SPS HARQ-ACK from the HARQ-ACK codebook, and determines whether the release of the SPS resource was successful and whether the SPS transmission is correct.

[00312] Sixth modality

[00313] In the fifth mode, the base station can also indicate K1=2 of PDCCH indicates the release of SPS resources, i.e., performing HARQ-ACK feedback in the n+4 interval. Since the feedback is not performed in the same interval as SPS1, 2, 5 in the n+2 interval, it is not necessary to determine if the total number exceeds A and / or C. The feedback can be performed in the corresponding intervals. That is, the terminal feeds back the HARQ-ACKs of SPS1, 2, 5 in the n+1 interval and the HARQ-ACKs of PDCCH indicating SPS3, 5 resource release in the n+1 interval and the n+4 interval, respectively. The position of the PDCCH HARQ-ACK within the HARQ-ACK is determined according to the SLIV of SPS3. Petition 870220092961, dated 10 / 10 / 2022, page 62 / 332 59 / 80 in SPS3, 5 released by HARQ-ACK; SLIV conflict does not exist between the different feedback intervals; on the base station side, in the same way as above, the HARQ-ACKs from SPSs 1, 2 and 5 in interval n+1 are received in interval n+3, and the HARQ-ACKs from the PDCCHs indicating the release of SPS3 and 5 resources in interval n+1 are received in interval n+4, respectively, and the PDCCH indicating the release of SPS resources and the SPS HARQ-ACKs are obtained from them, and it is determined whether the release was successful and whether the SPS transmission is correct.

[00314] It should be noted that, in the above mode, only the sum of the quantity The quantity of SPS PDSCHs (B1) that needs to be received and the quantity of PDCCHs (B2) that indicates the release of SPS resources can be considered; only the maximum quantity C of point-to-point fusion PDSCHs supported to be received in a given interval can be considered, whether or not both a and C are considered, i.e., the determination is made according to the minimum value of a and C;

[00315] in the above modality, if the PDCCH that indicates the release of resources of SPS releases only one SPS, for example, it only releases SPS3, the processing mode is the same as above and is not described again;

[00316] In the above embodiment, if the period of SPS1 and SPS2 is assumed to be , the PDCCH indicating SPS resource release can also be transmitted in the interval n+1 when the interval n, n+4, n+8, etc. is transmitted, the period of SPS3 and SPS4 is 2 ms when the interval n, n+2, n+4, etc. is transmitted and, at this point, since the PDCCH indicating SPS resource release is not in the same interval as any SPS transmission, the HARQ-ACK of the PDCCH indicating SPS resource release does not need to be fed back which occupies the HARQ-ACK position corresponding to which SPS is in the semi-static codebook and therefore the feedback can be performed in a semi-static manner in the codebook in the related technique, i.e. if the HARQ-ACK of the SPS and the HARQ-ACK of the PDCCH indicating SPS resource release are transmitted in the same Petition 870220092961, dated 10 / 10 / 2022, p. 63 / 332 60 / 80 interval, there are HARQ-ACK positions of the corresponding SPS PDCCH and the PDCCH indicating SPS resource release in the HARQ-ACK, respectively, which maps the HARQ-ACK to the corresponding positions, if the SPS HARQ-ACK and the PDCCH HARQ-ACK indicating SPS resource release are not transmitted in the same interval, which transmits, respectively, in HARQ-ACK codebooks in different PUCCHs in the same method 2, and the HARQ-ACK transmission between the SPS and the PDCCH indicating SPS resource release does not conflict;

[00317] it should be noted that, in the above modality, only the feedback of HARQ-ACK based on interval is taken as an example (i.e., the K1 unit is an interval), and the method is also applicable to HARQ-ACK feedback based on subinterval (i.e., the K1 unit is a subinterval); when the K1 defined in the above mode contains more values, the set of downlink transmission opportunities corresponding to the HARQ-ACK codebook in only one uplink interval is extended from one interval to multiple intervals, and the same applies if there is a PDCCH indicating SPS resource release in each interval containing SPS transmission.
