Patent Description:
Entire information about hybrid automatic repeat request acknowledgment (Hybrid Automatic Repeat Request Acknowledgment, HARQ-ACK) fed back by user equipment (User Equipment, UE, also referred to as terminal) on a hybrid automatic repeat request (Hybrid Automatic Repeat Request, HARQ) feedback resource (physical uplink control channel (Physical Uplink Control Channel, PUCCH) or physical uplink shared channel (Physical Uplink Shared Channel, PUSCH)) is referred to as an HARQ-ACK codebook.

The semi-static HARQ-ACK codebook is also referred to as a type <NUM> HARQ-ACK codebook. A size of the codebook is unrelated to actual scheduling of physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) or transmission of physical downlink control channel (Physical Downlink Control Channel, PDCCH), but depends on a configuration of radio resource control (Radio Resource Control, RRC) or a predefined parameter. When an RRC parameter pdsch-HARQ-ACK-Codebook = semi-static, the RRC parameter is configured as the semi-static HARQ-ACK codebook.

A method for generating a semi-static HARQ-ACK codebook includes the following steps:.

When the UE supports simultaneous service transmission of two types of PDSCHs, TDRA tables and/or K<NUM> sets of the two types of PDSCHs can be configured individually. However, in this case, how to determine the semi-static HARQ-ACK codebook is a technical problem to be resolved.

<CIT> discloses a method for transmitting or receiving groupcast feedback, which includes: receiving first sidelink control information (SCI) and first data corresponding to the first SCI, the first SCI including first priority information, receiving second SCI and second data corresponding to the second SCI, the second SCI including second priority information, identifying whether first feedback information associated with the first data or second feedback information associated with the second data is transmitted based on the first priority information or the second priority information when a resource for the first feedback information and a resource for the second feedback information are overlapped, and transmitting one of the first feedback information or the second feedback information which is associated with higher priority. <CIT>, the priority date of which are prior to the date of filing of the present application and but were published after that date, discloses a method for transmitting a first physical uplink control channel (PUCCH) with first hybrid automatic repeat request acknowledgement (HARQ-ACK) information bits, which includes: receiving information for a set of PUCCH resources; determining values for the first HARQ-ACK information bits, determining a PUCCH resource from the set of PUCCH resources according to a combination of positive acknowledgement values and negative acknowledgement values for the first HARQ-ACK information bits, and transmitting the first PUCCH using the PUCCH resource. <CIT> discloses a method of wireless communication performed by a user equipment (UE), which includes: receiving, from a network, a downlink transmission configuration indicating a transmit diversity downlink transmission mode of a plurality of downlink transmission modes; configuring downlink communication based on the transmit diversity downlink transmission mode according to the downlink transmission configuration; and receiving a service via point-to-multiple (PTM) downlink transmission based on the transmit diversity transmission mode. <CIT> anticipates an user equipment that may: determine slot timing values of a third set on the basis of slot timing values of a first set for a first DCI format and slot timing values of a second set for a second DCI format; determine valid time domain resource allocation values for each slot timing value in the slot timing values of the third set from among first time domain resource allocation values for the first DCI format and second time domain resource allocation values for the second DCI format; determine candidate PDSCH receptions on the basis of the slot timing values of the third set and the valid time domain resource allocation values; and transmit a HARQ-ACK codebook comprising HARQ-ACK information for the candidate PDSCH receptions.

The following specifically describes the method and terminal for generating a semi-static HARQ-ACK codebook provided in the embodiments of this application through specific embodiments and application scenarios thereof with reference to the accompanying drawings.

Referring to <FIG> shows a method for generating a semi-static HARQ-ACK codebook according to an embodiment of this application. The method is performed by a terminal and includes the following steps:
Step <NUM>: Determine, based on at least one of a K<NUM> set corresponding to a first PDSCH and a K<NUM> set corresponding to a second PDSCH, a K<NUM> set associated with an active UL BWP.

Step <NUM>: Determine, for each K<NUM>,k value in the K<NUM> set associated with the active UL BWP, based on at least one of a TDRA table corresponding to the first PDSCH and a TDRA table corresponding to the second PDSCH, a candidate PDSCH reception occasion in a slot corresponding to the K<NUM>,k value, where k = <NUM>,. , M-<NUM>, and M is the quantity of elements in the K<NUM> set associated with the active UL BWP.

In this embodiment of this application, based on the K<NUM> set associated with the active UL BWP, an HARQ-ACK feedback window can be determined. That is, for a specific UL slot, a PDSCH or PDCCH that needs to be fed back (for example, a PDCCH indicating SPS PDSCH release or a PDCCH indicating Scell dormancy) can only be transmitted in a slot within the HARQ-ACK feedback window. In other words, in the UL slot, only the PDSCH or PDCCH transmitted within the HARQ-ACK feedback window needs to be fed back.

Referring to <FIG>, assuming that the K<NUM> set associated with the active UL BWP is {<NUM>, <NUM>, <NUM>}, an HARQ-ACK feedback window corresponding to a slot of n+<NUM> is: n+<NUM> to n+<NUM>, where an offset value K<NUM>,k of n+<NUM> and n+<NUM> is <NUM>, an offset value K<NUM>,k of n+<NUM> and n+<NUM> is <NUM>, and an offset value K<NUM>,k of n+<NUM> and n+<NUM> is <NUM>.

Step <NUM>: Determine the semi-static HARQ-ACK codebook based on the candidate PDSCH reception occasion.

This embodiment of this application illustrates the method of determining a semi-static HARQ-ACK codebook in a case that the terminal supports simultaneous transmission of the first PDSCH and the second PDSCH, which can optimize the method of determining a semi-static HARQ-ACK codebook.

In this embodiment of this application, optionally, based on at least one of a K<NUM> set corresponding to a first PDSCH and a K<NUM> set corresponding to a second PDSCH, determining a K<NUM> set associated with an active UL BWP includes one of the following:.

This embodiment of this application illustrates the method for determining the K<NUM> set associated with the active UL BWP in a case that the terminal supports simultaneous transmission of the first PDSCH and the second PDSCH.

In this embodiment of this application, the determining, based on at least one of a TDRA table corresponding to the first PDSCH and a TDRA table corresponding to the second PDSCH, a candidate PDSCH reception occasion in a slot corresponding to the K<NUM>,k value includes:.

In this embodiment of this application, the union set of the TDRA table corresponding to the first PDSCH and the TDRA table corresponding to the second PDSCH is used to determine the candidate PDSCH reception occasion in the slot corresponding to the K<NUM>,k value only in a case the K<NUM>,k value in K<NUM> set associated with the active UL BWP belongs to the intersection set of the K<NUM> set corresponding to the first PDSCH and the K<NUM> set corresponding to the second PDSCH; and in a case that the K<NUM>,k value does not belong to the intersection set, only the TDRA table corresponding to the first PDSCH or the TDRA table corresponding to the second PDSCH is used to determine the candidate PDSCH reception occasion in the slot corresponding to the K<NUM>,k value, which can effectively reduce the size of the semi-static HARQ-ACK codebook.

In this embodiment of this application, optionally, in a case that the K<NUM>,k value does not belong to the intersection set, based on the row index of the TDRA table corresponding to the first PDSCH or the row index of the TDRA table corresponding to the second PDSCH, the determining the candidate PDSCH reception occasion in the slot corresponding to the K<NUM>,k value includes at least one of the following:.

In this embodiment of this application, in a case that a sub-slot (sub-slot) such as subslotLengthForPUCCH is configured for the UE, the slot in the foregoing embodiment can be replaced with the sub-slot to determine, for example, a candidate PDSCH reception occasion in the sub-slot corresponding to the K<NUM>,k value.

In the foregoing embodiment of this application, optionally, the first PDSCH and the second PDSCH correspond to different TDRA tables and/or K<NUM> sets.

In this embodiment of this application, the first PDSCH is a unicast PDSCH, and the second PDSCH is a multicast PDSCH.

It should be noted that in the present invention, the first PDSCH and the second PDSCH respectively represent two different types of PDSCHs, for example, the multicast PDSCH and the unicast PDSCH, or a PDSCH with a high priority and a PDSCH with a low priority. The terminal can determine the first PDSCH or the second PDSCH through a format of the DCI for scheduling the PDSCH, a control resource set (CORESET) to which the DCI belongs, a search space in which the DCI is located, or a scrambling RNTI of the PDSCH; or an RNTI for scrambling the CRC of the DCI for scheduling the PDSCH. This is not specifically limited in the present invention.

Currently, a broadcast or multicast feature is introduced to the new radio (New Radio, NR) technology. Broadcast and multicast services are mainly transmitted through the multicast PDSCH (also referred to as the broadcast PDSCH or a group-common PDSCH). The UE can receive the multicast PDSCH and the unicast PDSCH simultaneously, and TDRA tables and/or K<NUM> sets of the multicast PDSCH and the unicast PDSCH can be configured individually. When the UE supports simultaneous transmission of the unicast PDSCH and the multicast PDSCH, in a case that the candidate PDSCH reception occasion is determined directly based on the union set of the TDRA of the unicast PDSCH and the TDRA table of the multicast PDSCH, the size of the HARQ-ACK codebook is unnecessarily increased. Therefore, in a case that the UE supports the simultaneous transmission of the unicast PDSCH and the multicast PDSCH, the semi-static HARQ-ACK codebook can be determined in the method for generating a semi-static HARQ-ACK codebook described in the foregoing embodiment of this application, to optimize the method for determining the semi-static HARQ-ACK codebook. It should be noted that supporting the simultaneous transmission of the unicast PDSCH and the multicast PDSCH herein means supporting transmission of two types of services. Within a period of time, the UE can receive both the unicast PDSCH and the multicast PDSCH, which does not mean transmission of the unicast PDSCH and the multicast PDSCH on overlapped time domain symbols.

An example that the first PDSCH is a unicast PDSCH and the second PDSCH is a multicast PDSCH is provided below to describe the method for generating a semi-static HARQ-ACK codebook in this embodiment of this application.

Referring to <FIG>, a method for generating a semi-static HARQ-ACK codebook in this embodiment of this application includes the following steps:.

Step <NUM>: Determine, based on at least one of a K<NUM> set corresponding to a unicast PDSCH and a K<NUM> set corresponding to a multicast PDSCH, a K<NUM> set associated with an active UL BWP.

Optionally, the determining a K<NUM> set associated with an active UL BWP includes one of the following:.

It is assumed that the K<NUM> set corresponding to the unicast PDSCH is {<NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>}, and the K<NUM> set corresponding to the multicast PDSCH is {<NUM>, <NUM>, <NUM>}.

In this embodiment of this application, in a case that the K<NUM> set corresponding to the unicast PDSCH is used as the K<NUM> set associated with the active UL BWP, the K<NUM> set associated with the active UL BWP is {<NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>}.

In a case that the K<NUM> set corresponding to the multicast PDSCH is used as the K<NUM> set associated with the active UL BWP, the K<NUM> set associated with the active UL BWP is {<NUM>, <NUM>, <NUM>}.

In a case that the union set of the K<NUM> set corresponding to the unicast and the K<NUM> set corresponding to the multicast PDSCH is used as the K<NUM> set associated with the active UL BWP, the K<NUM> set associated with the active UL BWP is {<NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>}.

Step <NUM>: For each K<NUM>,k value in the K<NUM> set associated with the active UL BWP, determine, based on at least one of a TDRA table corresponding to the unicast PDSCH and a TDRA table corresponding to the multicast PDSCH, a candidate PDSCH reception occasion in a slot corresponding to each K<NUM>,k value, where k = <NUM>,. , M-<NUM>, and M is the quantity of elements in the K<NUM> set associated with the active UL BWP.

In a case that the K<NUM>,k value belongs to an intersection set of the K<NUM> set corresponding to the unicast and the K<NUM> set corresponding to the multicast PDSCH, determine, based on a union set of the TDRA table corresponding to the unicast PDSCH and the TDRA table corresponding to the multicast PDSCH, the candidate PDSCH reception occasion in the slot corresponding to the K<NUM>,k value;.

Referring to <FIG> is a schematic diagram of a TDRA table corresponding to a unicast PDSCH and a corresponding candidate PDSCH reception occasion according to an embodiment of this application. Referring to <FIG> is a schematic diagram of a TDRA table corresponding to a multicast PDSCH and a corresponding candidate PDSCH reception occasion according to an embodiment of this application.

It is assumed that the K<NUM> set that is associated with the active UL BWP determined in Step <NUM> is {<NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>}.

In a case that the K<NUM>,k value is <NUM> or <NUM>, the value belongs to an intersection set {<NUM>, <NUM>} of the K<NUM> set corresponding to the unicast PDSCH and the K<NUM> set corresponding to the multicast PDSCH. Based on the union set of the TDRA table corresponding to the unicast PDSCH and the TDRA table corresponding to the multicast PDSCH, the terminal determines the candidate PDSCH reception occasion in the slot corresponding to the K<NUM>,k value. Referring to <FIG> is a schematic diagram of a union set of TDRA tables corresponding to unicast and multicast PDSCHs and a corresponding candidate PDSCH reception occasion according to an embodiment of this application.

In a case that the K<NUM>,k value belongs to {<NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>}, the value only belongs to the K<NUM> set corresponding to the unicast PDSCH. Based on the TDRA table corresponding to the unicast PDSCH, the terminal determines the candidate PDSCH reception occasion in the slot corresponding to the K<NUM>,k value.

In a case that the K<NUM>,k value is <NUM>, the value only belongs to the K<NUM> set corresponding to the multicast PDSCH. Based on the TDRA table corresponding to the multicast PDSCH, the terminal determines the candidate PDSCH reception occasion in the slot corresponding to the K<NUM>,k value.

In the foregoing embodiment of this application, optionally, the determining a candidate PDSCH reception occasion in a slot corresponding to each K<NUM>,k value further includes at least one of the following:.

That is, after being compared with uplink and downlink slot format configurations of time division duplexing (Time Division Duplexing, TDD), a position of the candidate PDSCH reception occasion is determined to be valid. When a candidate PDSCH receiving position in a specific row of the TDRA is overlapped with the uplink symbol, the position of the candidate PDSCH reception occasion in this row is not a valid reception occasion and needs to be excluded.

Optionally, the uplink symbol is semi-statically configured, for example, uplink symbols configured via parameters TDD-UL-DL-ConfigurationCommon and TDD-UL-DL-ConfigDedicated.

(<NUM>) combining candidate PDSCH reception occasions overlapped on time-domain positions, to generate, for example, only <NUM> HARQ-ACK bit. That is, based on a TDRA table associated with a downlink BWP, rows with non-overlapped time-domain resources are obtained, and only one of overlapped rows is considered.

For example, it is assumed that the K<NUM> set associated with the active UL BWP is {<NUM>, <NUM>, <NUM>}. It is also assumed that in a downlink (Downlink, DL) slot corresponding to each K<NUM>,k, each row of the TDRA table of the PDSCH for determining the HARQ-ACK codebook is shown in <FIG>.

When K<NUM>,k = <NUM>, referring to <FIG>, assuming that all candidate PDSCH reception occasions do not conflict with the uplink symbol, all the candidate PDSCH reception occasions can be retained.

When K<NUM>,k = <NUM>, referring to <FIG>, assuming that PDSCH candidate positions in rows <NUM>, <NUM>, and <NUM> are overlapped with the uplink symbol, the PDSCH candidate positions are excluded.

When K<NUM>,k = <NUM>, assuming that all sets of candidate PDSCH reception occasions are overlapped with the uplink symbol, all the sets of candidate PDSCH reception occasions are excluded.

Therefore, a finally determined set of candidate PDSCH reception occasions is: MA,c={<NUM>,<NUM>,<NUM>,<NUM>,<NUM>,<NUM>,<NUM>,<NUM>,<NUM>}.

After the candidate PDSCH reception occasion is determined, the HARQ-ACK information also needs to be determined. The HARQ-ACK information can be determined in the following manner:.

in a case that the K<NUM>,k value belongs to an intersection set of the K<NUM> set corresponding to the first PDSCH and the K<NUM> set corresponding to the second PDSCH, determining, based on a union set of a row index of the TDRA table corresponding to the first PDSCH and a row index of the TDRA table corresponding to the second PDSCH, the candidate PDSCH reception occasion in the slot corresponding to the K<NUM>,k value; and
in a case that the K<NUM>,k value does not belong to the intersection set, determining, based on the row index of the TDRA table corresponding to the first PDSCH or the row index of the TDRA table corresponding to the second PDSCH, the candidate PDSCH reception occasion in the slot corresponding to the K<NUM>,k value,
wherein the first PDSCH is a unicast PDSCH, and the second PDSCH is a multicast PDSCH.
