Description

HARQ-ACK feedback method terminal, base station and storage medium

Technical Field

The present invention relates to the field of wireless communications technologies, and in particular, to a HARQ-ACK feedback method, a terminal, a base station, and a storage medium.

Background

In NR Rel-15, the SPS release PDCCH (PDCCH indicating SPS resource release) can only use fallback DCI (e.g. DCI format 1-0), and the fallback DCI does not include a carrier indication field and therefore does not support cross-carrier scheduling and indication, so the SPS release PDCCH in R15 can only indicate the SPS PDSCH on its own carrier to perform resource release, and the corresponding SPS release PDCCH needs HARQ-ACK feedback information, and the position of the HARQ-ACK of the SPS release PDCCH in the HARQ-ACK codebook (i.e. the HARQ-ACK information sequence that the UE needs to transmit to the base station on one uplink channel) is determined according to the time domain resource information (i.e. one SLIV in the TDRA table) corresponding to the SPS PDSCH that the SPS release resource is indicated by the SPS release PDCCH.

In NR R16, the SPS release PDCCH may use a non-fallback DCI format (e.g., DCI formats 1-1 and 1-2, etc.), the non-fallback DCI may include a carrier indication field, and when the non-fallback DCI includes the carrier indication field, cross-carrier scheduling and indication may be supported, so that the SPS release PDCCH transmitted on carrier CC1 may indicate to release resources of the SPS PDSCH transmitted on carrier CC2, that is, cross-carrier indication of the SPS release PDCCH is supported. In this way, following existing mechanisms, determining HARQ-ACK feedback location for SPS release PDCCH transmitted on CC1 using SLIV corresponding to SPS PDSCH on CC2 may not be possible because the TDRA table is configured independently for each CC. If the TDRA tables on CC1 and CC2 are different, the SLIV on CC2 may not be included in the TDRA table corresponding to CC1, so that according to the SLIV corresponding to SPS PDSCH on CC2, the HARQ-ACK position corresponding to SPS release PDCCH cannot be found in the HARQ-ACK codebook corresponding to CC1, and HARQ-ACK feedback on SPS release PDCCH cannot be implemented.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In order to facilitate clear description of technical solutions of the embodiments of the present invention, in each embodiment of the present invention, if words such as "first" and "second" are used to distinguish identical items or similar items with substantially identical functions and actions, a person skilled in the art may understand that words such as "first" and "second" do not limit the quantity and execution order.

In the 5G NR system, semi-Persistent Scheduling (SPS) Physical Downlink Shared CHannel (PDSCH) transmission and PDSCH (dynamic PDCCH) transmission with a corresponding Physical Downlink Control CHannel (PDCCH) are supported (i.e., the PDSCH is transmitted by one PDCCH schedule). When the SPS transmission is configured, the higher layer signaling configures an RNTI (e.g., CS-RNTI) corresponding to the SPS correspondingly for scrambling a PDCCH activating and deactivating the SPS transmission, and configures a transmission period of the SPS PDSCH correspondingly. When there is a service to perform SPS transmission, the base station may activate the terminal to perform SPS transmission according to the SPS configured period by transmitting a PDCCH indicating SPS activation, where the PDCCH indicating SPS activation includes related scheduling information such as frequency domain resource allocation, time domain resource allocation, MCS, and the like, and is used to determine a transmission opportunity of the SPS PDSCH.

The higher layer signaling configures N candidate HARQ-ACK timing values (i.e. K1 values, which are used to express a time interval between a PDSCH or SPS release PDCCH and a PUCCH transmitting HARQ-ACK feedback information thereof, for example, in units of slots or sub-slots) in advance for the terminal, where the value range of N is 1 to 8. HARQ-ACK timing of PDSCH with corresponding PDCCH and SPS release PDCCH by PDCCH

The bit HARQ-ACK timing indication domain indicates any one of N values configured in advance by the high-layer signaling, if the high-layer signaling only configures one K1 value, the PDCCH does not have the indication domain, and the K1 configured by the high-layer signaling is directly used. The specific HARQ-ACK timing is defined as that for PDSCH or SPS release PDCCH with end of transmission in slot n, its HARQ-ACK feedback is transmitted in slot n + K1, where,the slots here are slots defined by SCS of the carrier where the reference PUCCH transmission is located, i.e. the point where K1=0 is referenced is the last PUCCH transmission slot overlapping with PDSCH or SPS release PDCCH.

Semi-static (semi-static) and dynamic (dynamic) HARQ-ACK codebook (codebook) generation modes are supported in the 5G NR system. The HARQ-ACK codebook is a HARQ-ACK feedback sequence generated for downlink transmission (including a PDSCH and a PDCCH indicating downlink SPS resource release, and the PDCCH indicating downlink SPS resource release may also be referred to as SPS release PDCCH or SPS PDSCH release) in which HARQ-ACK feedback is performed on the same time domain position or uplink channel.

The Semi-static codebook may determine, according to the HARQ-ACK timing value in the K1 set, a position set Mc for performing downlink transmission of HARQ-ACK feedback in a slot (slot) or sub-slot (sub-slot) n on each carrier c (specifically, on a currently activated BWP on the carrier), and then may determine, according to Mc, the HARQ-ACK codebook transmitted in the slot or sub-slot n.

Specifically, taking the case of PUCCH based on slot transmission as an example, for each carrier c, according to each K1 value in the K1 set, a slot set Mc corresponding to the slot n for HARQ-ACK feedback is determined; in each time slot in the time slot set, further determining the maximum number of downlink transmissions in TDM in one time slot according to various time domain positions (one time domain position may be referred to as a SLIV, which expresses the combination of one start symbol and the number of transmission symbols) in pre-configured downlink time domain resource allocation information (a TDRA table or set, each row in the table represents a time domain scheduling condition, and may give information such as a start symbol, the number of symbols, and a scheduling timing sequence (i.e., the number of time slot intervals between a PDCCH and a scheduled PDSCH); if the terminal does not support receiving more than one uniform PDSCH in one time slot, determining that the time slot corresponds to 1 downlink transmission; if the terminal supports receiving more than one unique PDSCH in a timeslot, SLIV grouping can be performed according to a SLIV set in the TDRA table and a predetermined rule, to find a SLIV with the earliest first end position, and with this SLIV as a reference, find all SLIVs with start positions before the end position of this SLIV, use these SLIVs as a group to correspond to one possible downlink transmission position (this is because the overlapped SLIVs are only used to provide scheduling flexibility, but only one SLIV can be selected from the SLIVs for use in actual scheduling, and two PDSCHs cannot be scheduled to use the overlapped SLIVs at the same time), then remove these SLIVs in the SLIV set, and repeat the above steps for the remaining SLIVs until all the SLIVs included in the TDRA table are processed, so as to obtain multiple downlink transmission positions (downlink transmissions on these positions do not overlap).

Fig. 1 is a schematic diagram illustrating downlink transmission position determination in an embodiment of the present invention, and fig. 2 is a schematic diagram illustrating a downlink transmission position set in an embodiment of the present invention, as shown in fig. 1, a result obtained is that an element a/B/C is a group corresponding to one downlink transmission position, and an element D/E is a group corresponding to one downlink transmission position, so that a total of 2 downlink transmission positions is obtained; further, before determining the number of downlink transmissions, if a semi-static uplink and downlink timeslot structure is configured, if an uplink symbol exists in a symbol set included in an SLIV in a timeslot, the downlink transmission will not actually occur because of uplink and downlink resource conflict, so the SLIV may be removed from the SLIV set, and it is only indicated that the downlink transmission may exist in the timeslot if all symbols determined according to the downlink time domain resource allocation information in the timeslot are downlink or flexible symbols.

Obtaining the Mc corresponding to each carrier according to the above manner, determining HARQ-ACK codebook of the carrier c in slot n according to Mc, including the size of codebook and the specific content and sequence of HARQ-ACK (specifically, downlink transmission received on the carrier c, mapping HARQ-ACK of downlink transmission to corresponding positions according to the corresponding relationship between the received SLIV position and the position in Mc), and cascading HARQ-ACK codebook corresponding to each carrier according to the carrier numbering sequence to obtain the HARQ-ACK codebook to be transmitted in slot n by the UE finally. Specifically, taking a carrier and only one singular PDSCH transmission supported in one slot as an example, assuming that the K1 set is {2,3,4,5,6,7,8,9}, then the Mc set corresponding to the feedback HARq-ACK in the slot n +9 is determined as shown in fig. 2, where the slots determined according to K1=5 and 6 are semi-statically configured UL slots, and there is no uplink transmission, so the two slots are removed, thereby reducing redundant information of codebook.

In NR Rel-16, the SPS release PDCCH is supported to perform cross-carrier resource release indication, and the HARQ-ACK of the SPS release PDCCH cannot be fed back normally because the prior art cannot find the position of the HARQ-ACK corresponding to the SPS release PDCCH in the HARQ-ACK codebook. The embodiments of the invention provide a method for determining the position of HARQ-ACK of SPS release PDCCH when the SPS release PDCCH is transmitted by using non-fallback DCI format and cross-carrier indication is carried out, thereby carrying out correct HARQ-ACK feedback of the SPS release PDCCH.

The core idea of the embodiments of the present invention is that, when a semi-static HARQ-ACK codebook is configured, if active BWP transmission on a carrier c is performed on a PDCCH indicating SPS resource release, according to one configuration or predetermined time domain resource allocation information in a PDSCH time domain resource allocation information set for determining the HARQ-ACK codebook corresponding to the active BWP of the carrier c, the position of the HARQ-ACK of the PDCCH indicating SPS resource release in the HARQ-ACK codebook is determined, so as to generate and transmit the HARQ-ACK codebook including the HARQ-ACK of the PDCCH indicating SPS resource release.

Fig. 3 is a flowchart illustrating a HARQ-ACK feedback method according to an embodiment of the present invention, and as shown in fig. 3, the method includes:

step 300, determining the position of HARQ-ACK of a PDCCH indicating SPS resource release in HARQ-ACK codebook according to one configuration or predetermined time domain resource allocation information in a PDSCH time domain resource allocation information set;

in the embodiment of the invention, after the base station sends the SPS release PDCCH to the UE, the UE needs to have HARQ-ACK feedback information for the corresponding SPS release PDCCH, and before the UE feeds back the HARQ-ACK, the UE determines the position of the HARQ-ACK of the PDCCH for indicating SPS resource release in the HARQ-ACK codebook according to one configuration in a PDSCH time domain resource allocation information set or preset time domain resource allocation information.

The PDSCH time domain resource allocation information set comprises a plurality of time domain resource allocation information, the UE selects one time domain resource allocation information from the PDSCH time domain resource allocation information set according to a preset rule or an indication of a signaling, and the UE can determine the position of HARQ-ACK of a PDCCH indicating SPS resource release in the HARQ-ACK codebook according to the time domain resource allocation information.

And 301, generating and transmitting HARQ-ACK codebook containing HARQ-ACK of the PDCCH indicating SPS resource release based on the determined position.

After the UE determines the position of the HARQ-ACK in the HARQ-ACK codebook of the PDCCH indicating the SPS resource release according to the time domain resource allocation information, the HARQ-ACK codebook containing the HARQ-ACK of the PDCCH indicating the SPS resource release can be generated based on the determined position and sent to the base station, and the HARQ-ACK feedback of the SPS release PDCCH is completed.

According to the HARQ-ACK feedback method provided by the embodiment of the invention, the UE determines the position of the HARQ-ACK of the PDCCH indicating the SPS resource release in the HARQ-ACK codebook according to one configuration in the PDSCH time domain resource allocation information set or the preset time domain resource allocation information, and generates and transmits the HARQ-ACK codebook containing the HARQ-ACK of the PDCCH indicating the SPS resource release based on the determined position so as to realize the correct HARQ-ACK feedback of the SPS release PDCCH.

On the basis of the foregoing embodiment, the PDSCH time domain resource allocation information set may specifically be a first-type PDSCH time domain resource allocation information set. The first PDSCH time domain resource allocation information set consists of PDSCH time domain resource allocation information provided by public PDSCH configuration information or PDSCH time domain resource allocation information provided by a default PDSCH time domain resource allocation table A;

specifically, the PDSCH time domain resource allocation information includes PDSCH time domain resource allocation information (PDSCH-time domain allocation list in PDSCH-ConfigCommon) provided in the common PDSCH configuration information or PDSCH time domain resource allocation information provided in a Default PDSCH time domain resource allocation table a.

When the PDSCH time domain resource allocation information is provided through dedicated PDSCH configuration information (PDSCH-config), the PDSCH time domain resource allocation information set may specifically be a second-type PDSCH time domain resource allocation information set, or a union of a first-type PDSCH time domain resource allocation information set and a second-type PDSCH time domain resource allocation information set.

The second type PDSCH time domain resource allocation information set is composed of time domain resource allocation information in one or more PDSCH time domain resource allocation lists provided by dedicated PDSCH configuration information.

Specifically, when PDSCH time domain resource allocation information (PDSCH-time domain allocation list in PDSCH-configuration and/or resource allocation-forward channel allocation 1_2in PDSCH-configuration) is provided by dedicated PDSCH configuration information, the PDSCH time domain resource allocation information set is a second-type PDSCH time domain resource allocation information set or a union of the first-type PDSCH time domain resource allocation information set and a second-type PDSCH time domain resource allocation information set, wherein the second-type PDSCH time domain resource allocation information set is formed by time domain resource allocation information in one or more PDSCH time domain resource allocation lists provided by the dedicated PDSCH configuration information.

For example, when the dedicated PDSCH configuration information provides only one PDSCH time domain resource allocation information list and corresponds to a certain DCI format, for example, one of DCI formats 1-1 or 1-2, the second type of PDSCH time domain resource allocation information set is the time domain resource allocation information in the PDSCH time domain resource allocation information list, and when the dedicated PDSCH configuration information provides a plurality of PDSCH time domain resource allocation information lists and corresponds to different DCI formats, for example, a list is provided for DCI formats 1-1 and 1-2, respectively, and the second type of PDSCH time domain resource allocation information set may be the time domain resource allocation information in a predetermined PDSCH time domain resource allocation information list in the plurality of PDSCH time domain resource allocation information lists or a union of the time domain resource allocation information in the plurality of PDSCH time domain resource allocation information lists.

On the basis of the foregoing embodiment, the configured or predetermined time domain resource allocation information specifically includes one of the following:

the method comprises the following steps: the configured or predetermined time domain resource allocation information specifically includes: and determining one time domain resource allocation information in the PDSCH time domain resource allocation information set according to the indication of the configuration signaling. Specifically, the configuration signaling may be higher layer signaling or signaling carried through a PDCCH.

The second method comprises the following steps: the configured or predetermined time domain resource allocation information specifically includes: one time domain resource allocation information in the PDSCH time domain resource allocation information set indicated by a time domain resource indication field in a PDCCH for indicating SPS PDSCH resource release.

The third method comprises the following steps: the predetermined time domain resource allocation information in the PDSCH time domain resource allocation information set specifically includes one of the following modes:

mode 1: and the predetermined time domain resource allocation information is the time domain resource allocation information corresponding to the lowest or highest number in the PDSCH time domain resource allocation information set.

Mode 2: and removing time domain resource allocation information corresponding to the SPS PDSCH (activated PDSCH) transmitted on the same activated BWP of the same carrier with the PDCCH for indicating the SPS resource release from the PDSCH time domain resource allocation information set to obtain an updated PDSCH time domain resource allocation information set, wherein the predetermined time domain resource allocation information is the time domain resource allocation information corresponding to the lowest number or the highest number in the updated PDSCH time domain resource allocation information set.

Mode 3: and removing time domain resource allocation information corresponding to the SPS PDSCH (activated) transmitted on the same activated BWP of the same carrier and in the same time unit by the PDCCH for indicating the SPS resource release from the PDSCH time domain resource allocation information set to obtain an updated PDSCH time domain resource allocation information set, wherein the predetermined time domain resource allocation information is the time domain resource allocation information corresponding to the lowest number or the highest number in the updated PDSCH time domain resource allocation information set. The time unit described in the embodiments of the present invention may be a predetermined one or more subframes, slots, subslots, and the like.

Mode 4: when the PDSCH time domain resource allocation information set only includes a first type PDSCH time domain resource allocation information set, the predetermined one time domain resource allocation information is the first or last time domain resource allocation information in the first type PDSCH time domain resource allocation information set (i.e. the time domain resource allocation information corresponding to the lowest number or the highest number, which is the same as below and is not described again);

when the PDSCH time domain resource allocation information set comprises a second PDSCH time domain resource allocation information set, the predetermined time domain resource allocation information is the first time domain resource allocation information or the last time domain resource allocation information in the second PDSCH time domain resource allocation information set.

It can be seen that in the mode 4, if only the common TDRA table is included (i.e. the PDSCH time domain resource allocation information set provided by the common signaling), one common SLIV is used (i.e. one time domain resource allocation information in the PDSCH time domain resource allocation information set, including the start symbol, the symbol length, and other information for determining the time domain resource position); if dedicated TDRA (i.e. the PDSCH time domain resource allocation information set provided by the dedicated PDSCH configuration information described above) is included, then one of the SLIVs in the dedicated mode, i.e. the SLIV in the dedicated mode 4, is preferably selected.

Mode 5: and removing time domain resource allocation information corresponding to the SPS PDSCH (activated) transmitted on the same activated BWP of the same carrier by the PDCCH for indicating the SPS resource release from the PDSCH time domain resource allocation information set, or removing time domain resource allocation information corresponding to the SPS PDSCH (activated) transmitted on the same activated BWP of the same carrier by the PDCCH for indicating the SPS resource release and in the same time unit, thereby obtaining an updated PDSCH time domain resource allocation information set.

When the updated PDSCH time domain resource allocation information set only contains a first PDSCH time domain resource allocation information set, the predetermined time domain resource allocation information is the first or last time domain resource allocation information in the first PDSCH time domain resource allocation information set contained in the updated PDSCH time domain resource allocation information set; when the updated PDSCH time domain resource allocation information set comprises a second PDSCH time domain resource allocation information set, the predetermined time domain resource allocation information is the first or last time domain resource allocation information in the second PDSCH time domain resource allocation information set in the updated PDSCH time domain resource allocation information set.

It can be seen that the mode 5 is a combination of the mode 2/3 and the mode 4, specifically, the mode 2/3 is executed first, and then the mode 4 is executed.

Mode 6: when the PDSCH time domain resource allocation information set only contains a first type PDSCH time domain resource allocation information set, removing, in the first type PDSCH time domain resource allocation information set, time domain resource allocation information corresponding to (activated) SPS PDSCH transmitted on the same activated BWP of the same carrier with the PDCCH indicating SPS resource release, or removing time domain resource allocation information corresponding to (activated) SPS PDSCH transmitted on the same activated BWP of the same carrier with the PDCCH indicating SPS resource release and in the same time unit, to obtain an updated first type PDSCH time domain resource allocation information set, where the predetermined one time domain resource allocation information is the first or last time domain resource allocation information in the updated first type PDSCH time domain resource allocation information set.

When the PDSCH time domain resource allocation information set comprises a second PDSCH time domain resource allocation information set, removing, in the second PDSCH time domain resource allocation information set, time domain resource allocation information corresponding to the SPS PDSCH (activated) transmitted on the same activated BWP of the same carrier as the PDCCH indicating SPS resource release, or removing time domain resource allocation information corresponding to the SPS PDSCH (activated) transmitted on the same activated BWP of the same carrier and in the same time unit as the PDCCH indicating SPS resource release, to obtain an updated second PDSCH time domain resource allocation information set, where the predetermined one time domain resource allocation information is the first or last time domain resource allocation information in the updated second PDSCH time domain resource allocation information set

It can be seen that mode 6 is a combination of mode 2/3 and mode 4, specifically mode 2/3 is performed in different conditions of mode 4.

Mode 7: the predetermined time domain resource allocation information is the first or last time domain resource allocation information in the first type PDSCH time domain resource allocation information set.

It can be seen that in mode 7, one SLIV in the common TDRA table is always used, since it is assumed that the common TDRA table is always present.

Mode 8: removing time domain resource allocation information corresponding to the SPS PDSCH (activated) transmitted on the same activated BWP of the same carrier with the PDCCH for indicating the SPS resource release from the PDSCH time domain resource allocation information set, or removing time domain resource allocation information corresponding to the SPS PDSCH (activated) transmitted on the same activated BWP of the same carrier with the PDCCH for indicating the SPS resource release and in the same time unit, so as to obtain an updated PDSCH time domain resource allocation information set; the predetermined time domain resource allocation information is the first or last time domain resource allocation information in the first type PDSCH time domain resource allocation information set in the updated PDSCH time domain resource allocation information set.

It can be seen that the mode 8 is a combination of the modes 2/3 and the mode 7, specifically, the mode 2/3 is executed first, and then the mode 7 is executed.

Mode 9: removing time domain resource allocation information corresponding to the SPS PDSCH (activated) transmitted on the same activated BWP of the same carrier with the PDCCH for indicating the SPS resource release from the first PDSCH time domain resource allocation information set, or removing time domain resource allocation information corresponding to the SPS PDSCH (activated) transmitted on the same activated BWP of the same carrier with the PDCCH for indicating the SPS resource release and in the same time unit, so as to obtain an updated first PDSCH time domain resource allocation information set; the predetermined time domain resource allocation information is the first or last time domain resource allocation information in the updated first type PDSCH time domain resource allocation information set.

It can be seen that mode 9 is a combination of mode 2/3 and mode 7, specifically mode 2/3 is performed in mode 7.

Mode 10: when the PDSCH time domain resource allocation information set comprises a first PDSCH time domain resource allocation information set, the predetermined time domain resource allocation information is the first or last time domain resource allocation information in the first PDSCH time domain resource allocation information set; when the PDSCH time domain resource allocation information set only contains a second PDSCH time domain resource allocation information set, the preset time domain resource allocation information is the first time domain resource allocation information or the last time domain resource allocation information in the second PDSCH time domain resource allocation information set.

It can be seen that in approach 10, if a common TDRA table is included, then one of the common SLIVs is used; if no common TDRA is contained, i.e. only dedicated TDRA is contained, then one SLIV in the dedicated, i.e. mode 10, is preferably selected to use the SLIV in the common TDRA table.

Mode 11: and removing time domain resource allocation information corresponding to the SPS PDSCH (activated) transmitted on the same activated BWP of the same carrier by the PDCCH for indicating the SPS resource release from the PDSCH time domain resource allocation information set, or removing time domain resource allocation information corresponding to the SPS PDSCH (activated) transmitted on the same activated BWP of the same carrier by the PDCCH for indicating the SPS resource release and in the same time unit, thereby obtaining an updated PDSCH time domain resource allocation information set.

When the updated PDSCH time domain resource allocation information set comprises a first PDSCH time domain resource allocation information set, the preset time domain resource allocation information is the first or last time domain resource allocation information in the first PDSCH time domain resource allocation information set in the updated PDSCH time domain resource allocation information set; when the updated PDSCH time domain resource allocation information set only contains a second PDSCH time domain resource allocation information set, the predetermined time domain resource allocation information is the first or last time domain resource allocation information in the second PDSCH time domain resource allocation information set in the updated PDSCH time domain resource allocation information set.

It can be seen that the mode 11 is a combination of the modes 2/3 and the mode 10, specifically, the mode 2/3 is executed first, and then the mode 10 is executed.

Mode 12: when the PDSCH time domain resource allocation information set comprises a first PDSCH time domain resource allocation information set, removing time domain resource allocation information corresponding to the SPS PDSCH (activated) transmitted on the same activated BWP of the same carrier by the PDCCH for indicating the SPS resource release from the first PDSCH time domain resource allocation information set, or removing time domain resource allocation information corresponding to the SPS PDSCH (activated) transmitted on the same activated BWP of the same carrier and in the same time unit by the PDCCH for indicating the SPS resource release, and obtaining an updated first PDSCH time domain resource allocation information set.

The predetermined time domain resource allocation information is the first or last time domain resource allocation information in the updated first type PDSCH time domain resource allocation information set; when the PDSCH time domain resource allocation information set only contains a second PDSCH time domain resource allocation information set, removing time domain resource allocation information corresponding to the SPS PDSCH (activated) transmitted on the same activated BWP of the same carrier by the PDCCH for indicating SPS resource release from the second PDSCH time domain resource allocation information set, or removing time domain resource allocation information corresponding to the SPS PDSCH (activated) transmitted on the same activated BWP of the same carrier by the PDCCH for indicating SPS resource release and in the same time unit, and obtaining an updated second PDSCH time domain resource allocation information set; the predetermined time domain resource allocation information is the first or last time domain resource allocation information in the updated second type PDSCH time domain resource allocation information set;

it can be seen that mode 12 is a combination of mode 2/3 and mode 10, specifically mode 2/3 is performed in different conditions of mode 10.

When the scheme 4 is employed, since table2 exists, it is always determined that the SLIV with the smallest number among table2 is used to determine the location of HARQ-ACK for a PDCCH indicating SPS resource release.

When the mode 5 is adopted, one implementation is: firstly, obtaining table3 'according to the above mode 2, and then determining the SLIV with the minimum number in table2 contained in table3' because the table3 'contains the element of table2 (because one SLIV in table2 is removed, the SLIV with the minimum number in current table2' is the second SLIV in original table2, and therefore is different from the SLIV obtained in the above mode 4) for determining the position of HARQ-ACK of PDCCH indicating SPS resource release; the other realization mode is as follows: firstly, it is determined that table3 does not need to be changed according to the above-mentioned method 3, and it is determined that the SLIV is the SLIV with the smallest number in table2 included in table3, and is used for determining the location of HARQ-ACK of PDCCH indicating SPS resource release (the obtained result is the same as method 4).

When mode 6 is employed, one implementation: because table2 exists, the SLIV is selected from table2, the processing of the mode 2 is executed on table2 to obtain table2 '(one SLIV in table2 is removed), and the SLIV with the smallest number in table2' is determined to be used for determining the position of HARQ-ACK of the PDCCH indicating SPS resource release (the obtained result is different from the mode 4 and is the same as the first mode of the mode 5); the other realization mode is as follows: because table2 exists, the SLIV is selected from table2, mode 3 is executed on table2 first, SLIV does not need to be removed, and the SLIV with the minimum number in table2 is determined to be used for determining the position of HARQ-ACK of the PDCCH indicating SPS resource release (the obtained result is the same as mode 4);

when the method 7 is adopted, since table1 exists, it is always determined that SLIV numbered 0 in table1 is used to determine the location of HARQ-ACK of PDCCH indicating SPS resource release.

When the mode 8 is adopted, one implementation is: firstly, obtaining table3' according to the above mode 2, and then determining the SLIV with the minimum number in table1 contained in table3' (because the SLIV in table1 is not removed, the result is the same as the SLIV obtained in the above mode 7) for determining the position of HARQ-ACK of PDCCH indicating SPS resource release because the table3' contains the element of table 1; the other realization mode is as follows: firstly, it is determined that table3 does not need to be changed according to the above-mentioned method 3, and it is determined that the SLIV is the SLIV with the smallest number in table1 included in table3, and is used for determining the location of HARQ-ACK of PDCCH indicating SPS resource release (the obtained result is the same as method 7).

When mode 9 is employed, one implementation: because table1 exists, SLIVs are selected from table1, a mode 2 is executed on table1 first, SLIVs do not need to be removed, and the SLIV with the minimum number in table1 is determined to be used for determining the position of HARQ-ACK of the PDCCH indicating SPS resource release (the obtained result is the same as mode 7); the other realization mode is as follows: because table1 exists, SLIV is selected from table1, and mode 3 is executed on table1 first, SLIV does not need to be removed, and the SLIV with the smallest number in table1 is determined to be used for determining the position of HARQ-ACK of PDCCH indicating SPS resource release (the obtained result is the same as mode 7).
