Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

Before describing the feedback method of HARQ-ACK information provided in the embodiment of the present application in detail, related knowledge, application scenario and implementation environment related to the embodiment of the present application are first described briefly.

First, the technical terms provided in the present application will be briefly described.

HARQ: the mechanism may use Stop-and-Wait Protocol (also known as SQW Protocol) to send data. In the stop-and-wait protocol, the transmitting end stops waiting for feedback information after transmitting a transport block (Transmission Block, TB) using one HARQ process, which may also be referred to as a HARQ process. So that the transmitting end will stop waiting for acknowledgement after transmitting the TB. However, the above approach easily results in low user throughput, so in order to improve user throughput, a TB may be transmitted using multiple parallel HARQ processes, and when one HARQ process waits for feedback information, the transmitting end may continue to transmit the TB using another HARQ process. The HARQ processes together form a HARQ entity, each HARQ entity is responsible for maintaining a parallel downlink HARQ process and a parallel uplink HARQ process, and the HARQ entity combines a stop-and-wait protocol to allow the continuous transmission of the data blocks. In the HARQ process, the feedback information includes acknowledgement ACK information or negative acknowledgement NACK (Negative acknowledgement) information, which is ACK if the acknowledgement reception is successful, and NACK if the acknowledgement reception fails. Wherein the feedback sequence including ACK information or NACK information may be referred to as a HARQ-ACK codebook.

HARQ codebook: the whole of feedback information fed back by the terminal on one HARQ feedback resource is called HARQ codebook (or HARQ-ACK codebook). The Type-1 HARQ-ACK codebook includes HARQ-ACK information corresponding to a set of candidate PDSCH receivers (or candidate PDSCH receivers within a HARQ-ACK feedback window). The Type-3 HARQ-ACK codebook includes feedback information corresponding to all HARQ processes of all carriers in one PUCCH group (or one cell group).

Type-1 HARQ-ACK codebook feedback: the Type-1 HARQ-ACK codebook includes HARQ-ACK information corresponding to a set of candidate PDSCH receivers (or candidate PDSCH receivers within a HARQ-ACK feedback window).

If the terminal is configured with Type-1 HARQ-ACK codebook feedback, in the Type-1 HARQ-ACK codebook feedback, for a PDSCH without repeated transmission, if the terminal receives the PDSCH on a time unit n, the terminal should feed back HARQ-ACK information corresponding to the PDSCH on the time unit n+k; for the PDSCH with the repeated transmission times of R, if the terminal receives the PDSCH from the time unit n-R+1 to the time unit n, the terminal should feed back HARQ-ACK information corresponding to the PDSCH from the time unit n+k; if the terminal receives the DCI releasing the SPS PDSCH configuration in time element n, the terminal should feed back ACK information corresponding to the DCI in time element n+k. Wherein, for PDSCH repeatedly transmitted over multiple time units, time unit n+k is referenced according to the last time unit of the multiple time units. The time element n+k may be considered as a feedback time element, K being determined from the K1 value in the HARQ feedback timing set and/or HARQ feedback timing indication (PDSCH-to-harq_ feedback timing indicator) information. If the terminal needs to feed back the HARQ-ACK information of the candidate PDSCH receiver corresponding to the PDSCH on other feedback time units than the time unit n+k, the HARQ-ACK information of the candidate PDSCH receiver corresponding to the PDSCH is set as NACK information.

One feedback time unit corresponds to a set of candidate PDSCH receivers (or candidate PDSCH receivers within one HARQ-ACK feedback window). The Type-1 HARQ-ACK codebook transmitted in the feedback time unit includes HARQ-ACK information corresponding to the set of candidate PDSCH receivers. The set of candidate PDSCH receivers is determined from the K1 value in the HARQ feedback timing set and a time domain resource allocation (Time domain resource assignment, TDRA) table. If the terminal receives the scheduling of at least part of PDSCH (including scheduled PDSCH and/or SPS PDSCH) in a set of candidate PDSCH receivers, and the feedback time unit corresponding to the at least part of PDSCH is the feedback time unit, the HARQ-ACK information corresponding to the at least part of PDSCH is included in the HARQ-ACK codebook transmitted on the feedback time unit, for example, the corresponding HARQ-ACK information is fed back at the position corresponding to the at least part of PDSCH in the Type-1 HARQ-ACK codebook transmitted on the feedback time unit. For the non-scheduled candidate PDSCH receiver or the PDSCH not indicated to be fed back through the feedback time unit, NACK information is set at a corresponding position in the Type-1 HARQ-ACK codebook transmitted on the feedback time unit.

It should be noted that, in a set of candidate PDSCH receivers corresponding to one feedback time unit, if the terminal receives only one PDSCH and the DCI format for scheduling the PDSCH includes C-DAI information and the C-DAI indication 1, or if the terminal receives only SPS PDSCH, or if the terminal receives only DCI for releasing SPS PDSCH configuration, the terminal feeds back only HARQ-ACK information corresponding to the PDSCH corresponding to the corresponding C-DAI indication 1, or only HARQ-ACK information corresponding to the SPS PDSCH, or only ACK information corresponding to the DCI for releasing SPS PDSCH configuration. That is, in these cases, the terminal does not need to feed back the Type-1 HARQ-ACK codebook.

Type-3 HARQ-ACK codebook feedback: for downlink transmission, also called one-shot HARQ-ACK codebook feedback, the feedback may be configured for the terminal by the network device. If the network device configures Type-3 HARQ-ACK codebook feedback for the terminal, the network device may trigger the terminal to perform one-shot HARQ-ACK codebook feedback through DCI (Downlink Control Information ), for example, the one-shot HARQ-ACK codebook feedback indicates an effective PUCCH resource. The One-shot HARQ-ACK codebook comprises feedback information corresponding to all HARQ processes on all configured carriers in One PUCCH group, and the feedback information comprises ACK information or NACK information. For the HARQ process including downlink transmission, the feedback information corresponding to the HARQ process includes a decoding result of downlink transmission, and for the HARQ process not including downlink transmission, the feedback information corresponding to the HARQ process includes a preset value or an initial value.

For uplink transmission, if one-shot HARQ-ACK codebook feedback is configured, the network equipment can send feedback information corresponding to all HARQ processes on a carrier to the terminal through DCI. For the HARQ process including uplink transmission, the corresponding feedback information is a decoding result of the uplink transmission, and for the HARQ process not including uplink transmission, the corresponding feedback information is a preset value or an initial value. The uplink transmission includes DCI scheduled uplink transmission and CG (Configured Grant) scheduled uplink transmission.

At present, the one-shot HARQ-ACK codebook feedback may include two types, one is one-shot HARQ-ACK codebook feedback carrying NDI (New Data Indication ) information, and the other is one-shot HARQ-ACK codebook feedback not carrying NDI information. The NDI information may be used to determine whether the corresponding data is retransmission data or new data, and in general, when the data is new data, the current NDI information may be flipped with respect to the NDI information transmitted last time, so whether the data is new data or retransmission data may be determined based on whether the NDI information is flipped. For example, if the NDI information transmitted last time is "1", if the current NDI information is "0", it may be determined that the NDI information is flipped, so that it may be determined that the current data packet is a new data packet. As an example, the network device may configure through RRC (Radio Resource Control ) signaling whether the terminal needs to carry NDI information when making HARQ-ACK codebook feedback.

SPS PDSCH (Semi-Persistent Scheduling Physical Downlink Shared Channel ): in order to support periodic and substantially fixed traffic while reducing the frequent PDCCH (Physical Downlink Control Channel ) scheduling overhead, the NR system may support semi-static resource allocation. The semi-static resource configuration refers to that the network device configures resources for the terminal semi-static through a higher layer signaling, for example, the higher layer signaling is RRC signaling, and when there is a service requirement, the network device activates the semi-static resource configuration for the terminal through DCI carried by the PDCCH, so that the terminal can receive service data according to the configured resources in each fixed period.

Alternatively, the terminal may be configured with SPS configuration resources, and the network device may indicate, by activation or deactivation, whether the terminal is SPS PDSCH transmission on the SPS configuration resources. The SPS configuration resource may be configured on the SpCell or the SCells. The network device needs to ensure that at most one cell in one cell group configures downlink SPS configuration resources, and along with the evolution of the version, multiple downlink SPS configuration resources can be configured in one cell group.

For downlink SPS configuration resources, activation and deactivation is mainly performed by DCI scrambled with CS-RNTI (Configured Scheduling-Radio Network Tempory Identity, configured scheduling-cell radio network temporary identity). As an example, if the terminal receives DCI of the CS-RNTI scrambling code and the NDI field corresponding to the enabling TB is set to "0", the terminal may determine whether a downlink SPS scheduling activation command or deactivation command (or release command) is received according to table 1 (special field setting of PDCCH for downlink SPS scheduling activation) and table 2 (special field setting of PDCCH for downlink SPS scheduling release). If the terminal receives a DCI with SPS PDSCH deactivated, the terminal is expected to perform corresponding HARQ-ACK feedback after M symbols, where the M symbols are calculated from the last symbol of the PDCCH corresponding to the SPS PDSCH deactivated DCI. The value of N may be a preset value, which may be set based on the requirement.

TABLE 2

	DCI Format 1_0

If the terminal is configured and activates a downlink SPS transmission, the terminal receives an SPS PDSCH transmitted by the network device on a downlink SPS configuration resource, wherein the SPS PDSCH is periodically transmitted on the downlink SPS configuration resource, and the SPS PDSCH has no corresponding PDCCH schedule.

The SPS PDSCH transmitted on the downlink SPS configuration resources includes only the initial transmission since there is no PDCCH scheduling. If a certain HARQ process fails to be retransmitted initially, the network device schedules the same HARQ process through DCI scrambled by the CS-RNTI, and sets the NDI field to "1", or if the terminal receives DCI scrambled by the CS-RNTI and the NDI field is set to "1", the terminal considers that the DCI schedules the HARQ process for retransmission.

CG-PUSCH (Configured Grant Physical Uplink Shared Channel, preconfigured grant physical uplink shared channel): to support periodic and substantially fixed traffic while reducing the frequent PDCCH (Physical Downlink Control Channel ) scheduling overhead, the NR system may support semi-static uplink resource allocation. The semi-static resource configuration refers to that the network device semi-statically configures resources for the terminal through higher layer signaling, for example, the higher layer signaling is RRC signaling. In NR systems, pre-configured grant uplink transmission without dynamic grant scheduling may be performed through CG resources semi-statically configured by higher layer signaling. There are two implementations in particular, namely that its actual uplink grant can be obtained through RRC configuration (type 1) or PDCCH (type 2) scrambled by CS-RNTI. The terminal may send traffic data through the activated (or authorized) semi-static resource configuration when there is a traffic demand. The activation and deactivation modes of the CG-PUSCH resource of the Type 2 are similar to those of the SPS PDSCH resource.

Next, the application scenario related to the present application will be briefly described.

In an NR system, a network device may configure SPS configuration resources (also may be referred to as semi-persistent resources) for a terminal and determine whether to perform SPS PDSCH transmission on the SPS configuration resources through activation signaling or deactivation signaling. In this way, if SPS PDSCH transmission is supported, and at the same time, when the terminal is triggered to perform HARQ-ACK codebook feedback, how to perform HARQ-ACK information feedback becomes a research hotspot, for this reason, the embodiments of the present application provide a HARQ codebook feedback method, and specific implementation of the HARQ codebook feedback method may be seen in the following embodiments.

Generally, the number of connections supported by the conventional communication system is limited and easy to implement, however, with the development of communication technology, the mobile communication system will support not only conventional communication but also, for example, D2D (Device to Device) communication, M2M (Machine to Machine ) communication, MTC (Machine Type Communication ), V2V (Vehicle to Vehicle, inter-vehicle) communication, and V2X (Vehicle To Everything, internet of vehicles) systems, etc. The embodiments of the present application may also be applied to these communication systems.

The first control information is used to schedule transmission of the first physical channel. The second control information is used to schedule transmission of the second physical channel. The third control information is used to release the physical channel configuration of the semi-persistent scheduling.

And the implementation mode is three: the terminal determines whether to transmit the HARQ-ACK information through the first feedback time unit according to the receiving condition of at least one first physical channel, the receiving condition of at least one second physical channel and/or the distribution indication counting information in at least one control information.

The second physical channel corresponds to a HARQ process of a second state.

Optionally, the HARQ process corresponding to the second state includes at least one of:

HARQ process corresponds to enabled state;

HARQ process is not configured to enable parameters;

HARQ process corresponds to HARQ-ACK feedback.

Optionally, the second physical channel includes PDSCH of the HARQ process of the second state scheduled by the PDCCH, and/or SPSPDSCH of the HARQ process of the second state.

In summary, in the method provided in this embodiment, the terminal may determine whether to feed back the HARQ-ACK information according to the receiving condition of the first physical channel in the received physical channels, so as to ensure consistency of the network device and the terminal in whether to feed back the HARQ-ACK information.

Implementation one for step 204:

fig. 3 is a flowchart illustrating a feedback method of HARQ-ACK information according to an exemplary embodiment of the present application. The embodiment is applied to the terminal by the method. Alternatively, the terminal is an NTN-enabled terminal. The method comprises the following steps:

step 302: the terminal receives at least one piece of first control information;

the first control information is used to schedule transmission of the first physical channel. Illustratively, the first control information is for scheduling transmission of the first physical channel on at least one transmission opportunity of the first set of candidate physical channel transmission opportunities.

Step 304: the terminal receives a first physical channel according to the first control information;

The terminal receives a first physical channel on a transmission opportunity indicated by the first control information.

In the dynamic scheduling scenario, the first control information and the first physical channel may be in a one-to-one correspondence. For example, when receiving the first control information a, the terminal receives a first physical channel a according to the first control information a; and the terminal receives the first physical channel A according to the first control information B under the condition of receiving the first control information B.

In the scenario of semi-persistent scheduling, the first control information and the first physical channel may be a one-to-many correspondence, for example, when the terminal receives the first control information a, the terminal receives a plurality of first physical channels of semi-persistent scheduling according to the first control information a.

Step 306: and the terminal determines whether to transmit the HARQ-ACK information through the first feedback time unit according to the receiving condition of the first physical channel.

The terminal receives a first physical channel in a first candidate physical channel receiver set, and the terminal determines whether to transmit HARQ-ACK information through a first feedback time unit according to the receiving condition of the first physical channel.

The first candidate physical channel receiver set includes at least one candidate physical channel receiver on at least one serving cell, and corresponds to a first feedback time unit.

In some embodiments, the terminal does not transmit HARQ-ACK information through the first feedback time unit in the case where the terminal receives only m first physical channels in the first candidate physical channel receiver set and does not receive the second physical channel. Or, if at least one physical channel received by the terminal in the first candidate physical channel receiver set is the first physical channel, the terminal does not transmit HARQ-ACK information through the first feedback time unit.

For example, as shown in fig. 4, the terminal receives only 4 first physical channels, i.e., PDSCH1, PDSCH2, PDSCH3, PDSCH4, and does not receive a second physical channel in the first candidate physical channel receiver set, and the terminal does not transmit HARQ-ACK information through the first feedback time unit. If the terminal is configured with the HARQ codebook feedback of type one, the terminal does not perform the feedback of the HARQ codebook of type one.

In some embodiments, the terminal does not transmit HARQ-ACK information through the first feedback time unit in the case of the semi-persistently scheduled first physical channel received in the first candidate physical channel receiver set.

That is, the terminal does not transmit HARQ-ACK information through the first feedback time unit in the case where only the first physical channel is received and no second physical channel is received in the first candidate physical channel receiver set. If the terminal is configured with the HARQ codebook feedback of the type one, the terminal does not perform the feedback of the HARQ codebook of the type one; if the terminal is configured with the feedback of the type three HARQ codebook, the terminal does not perform the feedback of the type three HARQ codebook.

Implementation two for step 204:

fig. 5 is a flowchart illustrating a feedback method of HARQ-ACK information according to an exemplary embodiment of the present application. The embodiment is applied to the terminal by the method. Alternatively, the terminal is an NTN-enabled terminal. The method comprises the following steps:

step 502: the terminal receives at least one piece of control information;

the at least one control information includes: at least one of the first control information, the second control information, and the third control information.

The first control information is used to schedule transmission of the first physical channel in the first set of candidate physical channel transmission opportunities. The second control information is used to schedule transmission of the second physical channel in the first set of candidate physical channel transmission opportunities. The third control information is used to release the configuration of the semi-persistent scheduled physical channel. The semi-persistent scheduled physical channel is configured for transmission in a first set of candidate physical channel transmission opportunities. The semi-persistent scheduled physical channel may be a first physical channel or a second physical channel.

Step 504: the terminal receives a first physical channel according to the first control information;

Optionally, the first control information further carries a counter indicator count (C-DAI). The first control information may have a C-DAI or no C-DAI, which is not limited in the embodiment of the present application. For example, when the first control information corresponds to DCI format 1_0, there is a C-DAI in the first control information; when the first control information corresponds to the DCI format 1_1 or the DCI format 1_2, there is no C-DAI in the first control information. In a scenario where at least one first control information carries a C-DAI, or one first control information corresponds to one C-DAI, that is, one allocation indication count information corresponds to one first control information. Typically, each first control information corresponds to a first physical channel. In some special cases one first control information may correspond to a plurality of first physical channels.

The allocation indication count information in the first control information has at least two indication modes:

indication mode one: the allocation indication counting information carried in the first control information always indicates a first preset value; or, the allocation indication count information carried in the first control information indicates an arbitrary value. Illustratively, the first preset value takes on a value of 0, or, the first preset value is a power of 2 to n, n being the number of bits allocated to indicate the count information. That is, the allocation indication count information carried in the first control information always indicates a first preset value regardless of whether the second physical channel is transmitted in the first candidate physical channel opportunity group and regardless of whether the terminal receives the third control information; or, the allocation indication count information carried in the first control information indicates any value in the values corresponding to the n bits.

Indication mode II: the allocation indication counting information carried in the first control information is used for determining the bit number of the HARQ-ACK information to be fed back in the first feedback time unit until the first control information is reached. That is, the allocation indication count information carried in the first control information considers whether the second physical channel is transmitted in the first candidate physical channel receiver set, and whether the terminal receives the third control information.

The method includes that when the number of bits of HARQ-ACK information to be fed back in the first feedback time unit is not 0 until the first control information is terminated, the allocation indication count information is used for determining the number of bits of HARQ-ACK information to be fed back in the first feedback time unit until the first control information is terminated; and when the number of bits of the HARQ-ACK information to be fed back in the first feedback time unit is 0 until the first control information is cut off, the distribution indication counting information indicates a first preset value.

As shown in fig. 6, the allocation indication count information in the first control information corresponding to the physical channel 1 indicates a first preset value 4, which represents that the number of HARQ-ACK information to be fed back in the first candidate physical channel receiver set is 0; the distribution indication count information in the second control information corresponding to the physical channel 2 indicates a first preset value 1, and represents that the number of HARQ-ACK information to be fed back in the first candidate physical channel receiver group is 1; the indication count information in the first control information corresponding to the physical channel 3 indicates 1, which represents that the number of HARQ-ACK information to be fed back in the first candidate physical channel receiver set is 1, that is, 1-bit HARQ-ACK of the physical channel 2 needs to be fed back.

Step 506: and the terminal determines whether to transmit the HARQ-ACK information through the first feedback time unit according to the receiving condition of the at least one first physical channel and the distribution indication count information in the at least one control information.

According to two indication modes of the allocation indication count information in the first control information, the steps are respectively described as follows:

in the case of indication one: (the allocation indication count information in the first control information always indicates the first preset value or indicates an arbitrary value)

In some embodiments, the terminal does not transmit HARQ-ACK information through the first feedback time unit in case the terminal receives only m first physical channels in the first candidate physical channel receiver opportunity group. In this case, the terminal ignores the allocation indication count information in the first control information corresponding to the m first physical channels (i.e., the terminal does not read the allocation indication count information in the first control information corresponding to the m first physical channels).

In some embodiments, the terminal receives first control information, where the first control information is used to schedule transmission of a first physical channel, and the first control information carries the allocation indication count information; the terminal ignores the allocation indication count information in the first control information, and the terminal does not transmit the HARQ-ACK information through the first feedback time slot time unit.

In some embodiments, when the terminal receives only m first physical channels in the first candidate physical channel receiver set and the allocation indication count information in the first control information corresponding to the m first physical channels is a first preset value, the terminal does not transmit HARQ-ACK information through the first feedback time unit.

As shown in fig. 7, the terminal receives only 4 first physical channels, i.e., PDSCH1, PDSCH2, PDSCH3, PDSCH4, in the first candidate physical channel receiver set, and the allocation indication count information C-DAI corresponding to the 3 first control information DCIs corresponding to the 4 first physical channels is the first preset value 4, and the terminal does not transmit HARQ-ACK information through the first feedback time unit. If the terminal is configured with the HARQ codebook feedback of type one, the terminal does not perform the feedback of the HARQ codebook of type one. In this example, the C-DAI is not included in the first DCI 3 of the scheduled PDSCH 3.

In some embodiments, the terminal receives m first physical channels in the first candidate physical channel receiver set, and the allocation indication count information in the first control information corresponding to the m first physical channels indicates a first preset value, and the terminal does not transmit HARQ-ACK information through the first feedback time unit when no second physical channel is received.

In some embodiments, when the terminal receives m first physical channels in the first candidate physical channel receiver set, and at least one of the allocation indication count information in the first control information corresponding to the m first physical channels is a first preset value, and the allocation indication count information in the received third control information is 1, m is a positive integer, and the terminal transmits HARQ-ACK information (1 bit) of the third control information through the first feedback time unit. If the terminal is configured with the type one HARQ-ACK codebook, the fixed-length type one HARQ-ACK codebook does not need to be fed back.

As shown in fig. 8, the terminal receives 3 first physical channels, namely PDSCH1, PDSCH2, PDSCH3, in the first candidate physical channel receiver set, and the allocation indication count information C-DAI corresponding to the first control information (first DCI) corresponding to the 3 first physical channels is a first preset value 4, and the C-DAI in the received third control information (third DCI) is 1, and the terminal transmits HARQ-ACK information (1 bit) of the third control information through the first feedback time unit. If the terminal is configured with the type one HARQ-ACK codebook, the fixed-length type one HARQ-ACK codebook does not need to be fed back. In this example, the C-DAI is not included in the first DCI 1 of the scheduled PDSCH 1.

The third control information is used for indicating to release the physical channel configuration of semi-persistent scheduling, and the physical channel of the semi-persistent scheduling corresponds to the first candidate physical channel receiver set.

In the case of indication two: (the allocation indication count information in the first control information indicates the number of HARQ-ACKs that need feedback)

In some embodiments, in a case that the terminal receives m first physical channels in the first candidate physical channel receiver set and at least one of the allocation indication count information in the first control information corresponding to the m first physical channels is 1, the terminal transmits one HARQ-ACK information through the first feedback time unit.

As shown in fig. 9, the terminal receives 3 first physical channels, namely PDSCH1, PDSCH2, and PDSCH3, in the first candidate physical channel receiver set, and the allocation indication count information C-DAI corresponding to the first control information (first DCI) corresponding to one first physical channel in the 3 first physical channels is a first preset value 4, the C-DAI corresponding to the first DCI corresponding to the last first physical channel in the three first physical channels is 1, and the terminal transmits one HARQ-ACK information through the first feedback time unit. If the terminal is configured with the type one HARQ-ACK codebook, the fixed-length type one HARQ-ACK codebook does not need to be fed back. In this example, the C-DAI is not included in the first DCI 2 of the scheduled PDSCH 2.

Wherein one HARQ-ACK information corresponds to at least one of one physical channel, one second physical channel, one control information, one third control information, one bit of HARQ-ACK information, which is not limited in this application.

Optionally, the case of at least one of the allocation indication count information in the first control information corresponding to the m first physical channels includes at least one of the following manners:

at least one of the allocation indication count information in the first control information corresponding to the m first physical channels indicates 1; or, all the allocation indication count information in at least one allocation indication count information in the first control information corresponding to the m first physical channels indicates 1; or, the allocation indication count information in the first control information corresponding to the m first physical channels includes at least two allocation indication count information, where the at least two allocation indication count information indicates a first preset value or indicates 1, and the allocation indication count information for indicating the first preset value is located before the allocation indication count information for indicating 1.

In some embodiments, the terminal receives m first physical channels in the first candidate physical channel receiver set, and at least one of the allocation indication count information in the first control information corresponding to the m first physical channels allocates indication count information indication 1, and if the second physical channel is not received, the terminal transmits one HARQ-ACK information through the first feedback time unit.

In some embodiments, when the terminal receives m first physical channels in the first candidate physical channel receiver set and at least one of the allocation indication count information in the first control information corresponding to the m first physical channels is 1, and the allocation indication count information in the received third control information is 1, the terminal transmits HARQ-ACK information (1 bit) of the third control information through the first feedback time unit. If the terminal is configured with the type one HARQ-ACK codebook, the fixed-length type one HARQ-ACK codebook does not need to be fed back.

For example, as shown in fig. 10, the terminal receives 3 first physical channels, i.e., PDSCH1, PDSCH2, PDSCH3, in the first candidate physical channel receiver set, where the C-DAI in the first DCI corresponding to the 3 first physical channels is 1, and the C-DAI in the received third DCI is 1, and the terminal transmits HARQ-ACK information (1 bit) of the third control information through the first feedback time unit. If the terminal is configured with the type one HARQ-ACK codebook, the fixed-length type one HARQ-ACK codebook does not need to be fed back. In this example, the C-DAI is not included in the first DCI 3 of the scheduled PDSCH 3.

In some embodiments, the terminal feeds back only HARQ-ACK information (1 bit) of the third control information in the first feedback time unit in case that the terminal receives only the third control information in the first candidate physical channel reception opportunity group and the allocation indication count information in the third control information indicates 1. If the terminal is configured with the type one HARQ-ACK codebook, the fixed-length type one HARQ-ACK codebook does not need to be fed back.

Implementation three for step 204:

fig. 11 is a flowchart illustrating a feedback method of HARQ-ACK information according to an exemplary embodiment of the present application. The embodiment is applied to the terminal by the method. Alternatively, the terminal is an NTN-enabled terminal. The method comprises the following steps:

step 1102: the terminal receives at least one piece of control information;

Step 1104: the terminal receives a first physical channel according to the first control information and a second physical channel according to the second control information;

In the dynamic scheduling scenario, the first control information and the first physical channel may be in a one-to-one correspondence. For example, when receiving the first control information a, the terminal receives a first physical channel a according to the first control information a; and the terminal receives the first physical channel A according to the first control information B under the condition of receiving the first control information B. Similarly, in the dynamic scheduling scenario, the second control information and the second physical channel may be in a one-to-one correspondence.

In the scenario of semi-persistent scheduling, the first control information and the first physical channel may be a one-to-many correspondence, for example, when the terminal receives the first control information a, the terminal receives a plurality of first physical channels of semi-persistent scheduling according to the first control information a. Similarly, in the scenario of semi-persistent scheduling, the second control information and the second physical channel may be in a one-to-many correspondence.

Optionally, the first control information further carries a counter indicator count (C-DAI). The first control information may have a C-DAI or no C-DAI, which is not limited in the embodiment of the present application. For example, when the first control information corresponds to DCI format 1_0, there is a C-DAI in the first control information; when the first control information corresponds to the DCI format 1_1 or the DCI format 1_2, there is no C-DAI in the first control information.

Optionally, the second control information may also carry allocation indication count information. The allocation indication count information in the second control information is used for indicating the number of HARQ-ACK information to be fed back in the first candidate physical channel receiver set until the second control information is reached.

Step 1106: the terminal determines whether to transmit the HARQ-ACK information through the first feedback time unit according to the receiving condition of the at least one first physical channel, the receiving condition of the at least one second physical channel and the distribution indication count information in the at least one control information.

Based on the allocation indication count information in the first control information received by the terminal, the third mode may include the following two cases, where the two cases are respectively set forth as follows:

In some embodiments, when the terminal receives m first physical channels and one second physical channel in the first candidate physical channel receiver set, the allocation indication count information in the first control information corresponding to the m first physical channels is a first preset value, and the allocation indication count information in the second control information is 1, the terminal transmits HARQ-ACK information of the second physical channel through the first feedback time unit.

As shown in fig. 12, in an exemplary embodiment, a terminal receives 4 physical channels in a first candidate physical channel receiver set, including three first physical channels PDSCH1, PDSCH2, PDSCH3 and one second physical channel PDSCHx, wherein the allocation indication count information in the first control information corresponding to the three first physical channels is a first preset value 4, and the C-DAI in the second DCI corresponding to the second physical channel PDSCHx is 1, and the terminal transmits HARQ-ACK information of the second physical channel PDSCHx through a first feedback time unit. In this example, the C-DAI is not included in the first DCI 2 of the scheduled PDSCH 2.

In some embodiments, the terminal receives m first physical channels and one semi-persistently scheduled second physical channel in the first candidate physical channel receiver set, and the allocation indication count information in the first control information corresponding to the m first physical channels indicates a first preset value, and the terminal transmits HARQ-ACK information (1 bit) of the semi-persistently scheduled second physical channel through the first feedback time unit. If the terminal is configured with the type one HARQ-ACK codebook, the fixed-length type one HARQ-ACK codebook does not need to be fed back.

As shown in fig. 13, in an exemplary embodiment, a terminal receives 4 physical channels including three first physical channels PDSCH1, PDSCH2, PDSCH3 and one semi-persistent scheduling second physical channel SPS PDSCH in a first candidate physical channel receiver set, and the allocation indication count information in the first control information corresponding to the three first physical channels is a first preset value of 4, then the terminal transmits HARQ-ACK information (1 bit) of the semi-persistent scheduling second physical channel through a first feedback time unit. If the terminal is configured with the type one HARQ-ACK codebook, the fixed-length type one HARQ-ACK codebook does not need to be fed back. In this example, the C-DAI is not included in the first DCI 1 of the scheduled PDSCH 1.

In some embodiments, in a case that the terminal receives m first physical channels and one second physical channel in the first candidate physical channel receiver set, at least one of allocation indication count information in first control information corresponding to the m first physical channels is 1 and allocation indication count information in the second control information is 1, the terminal transmits HARQ-ACK information (1 bit) of the second physical channel through the first feedback time unit. If the terminal is configured with the type one HARQ-ACK codebook, the fixed-length type one HARQ-ACK codebook does not need to be fed back.

As shown in fig. 14, the terminal receives four physical channels in the first candidate physical channel receiver set, including three first physical channels PDSCH1, PDSCH2, PDSCH3 and one second physical channel PDSCHx, where C-DAI in the first control information corresponding to the three first physical channels is a first preset value of 1, and C-DAI in the second DCI corresponding to the second physical channel PDSCHx is 1, and the terminal transmits HARQ-ACK information (1 bit) of the second physical channel through the first feedback time unit. If the terminal is configured with the type one HARQ-ACK codebook, the fixed-length type one HARQ-ACK codebook does not need to be fed back. In this example, the C-DAI is not included in the first DCI 2 of the scheduled PDSCH 2.

In some embodiments, in a case that the terminal receives m first physical channels and one semi-persistently scheduled second physical channel in the first candidate physical channel receiver set, at least one of allocation indication count information in the first control information corresponding to the m first physical channels is 1, the terminal transmits HARQ-ACK information (1 bit) of the semi-persistently scheduled second physical channel through the first feedback time unit. If the terminal is configured with the type one HARQ-ACK codebook, the fixed-length type one HARQ-ACK codebook does not need to be fed back.

As shown in fig. 15, in an exemplary embodiment, a terminal receives 4 physical channels including three first physical channels PDSCH1, PDSCH2, PDSCH3 and one semi-persistent scheduling second physical channel SPS PDSCH in a first candidate physical channel receiver set, where C-DAI in first control information corresponding to the three first physical channels is a first preset value of 1, and the terminal transmits HARQ-ACK information (1 bit) of the semi-persistent scheduling second physical channel through a first feedback time unit. If the terminal is configured with the type one HARQ-ACK codebook, the fixed-length type one HARQ-ACK codebook does not need to be fed back. In this example, the C-DAI is not included in the first DCI 2 of the scheduled PDSCH 2.

In some embodiments, when the terminal receives the second physical channel on the primary cell in the first candidate physical channel receiver opportunity group, and the allocation indication count information in the second control information indicates 1, and receives at least one allocation indication count information in the first control information corresponding to m first physical channels, the terminal feeds back only one HARQ-ACK information (1 bit) through the first feedback time unit. If the terminal is configured with the type one HARQ-ACK codebook, the fixed-length type one HARQ-ACK codebook does not need to be fed back.

Optionally, before receiving the second control information, the terminal receives the first control information, and the allocation indication count information in the first control information indicates a first preset value; and/or the terminal receives the first control information after receiving the second control information, wherein the allocation indication count information in the first control information indicates 1.

Illustratively, as shown in fig. 16, the allocation indication count information includes 2 bit numbers, so the indication range of the allocation indication count information is 1 to 4. If the terminal receives only one second physical channel in the first candidate physical channel receiver set, and the allocation indication count information in the second control information indicates 1, that is, the allocation indication count information in the second control information corresponding to the physical channel 2 indicates 1, and receives two first physical channels, that is, the physical channel 1 and the physical channel 3, and the allocation indication count information in the first control information corresponding to the physical channel 1 indicates a first preset value 4, and the allocation indication count information in the first control information corresponding to the physical channel 3 indicates 1, the terminal only feeds back the HARQ-ACK information corresponding to the physical channel 2 transmitted by the second physical channel.

In some embodiments, the terminal feeds back only HARQ-ACK information (1 bit) of the second physical channel in the first feedback time unit in case that the terminal receives only the second physical channel on the primary cell in the first candidate physical channel receiver opportunity group and the allocation indication count information in the second control information indicates 1. If the terminal is configured with the type one HARQ-ACK codebook, the fixed-length type one HARQ-ACK codebook does not need to be fed back.

In some embodiments, the terminal receives only the semi-persistent scheduling physical channel transmitted by the second physical channel in the first candidate physical channel receiver set, and the terminal feeds back only HARQ-ACK information (1 bit) of the semi-persistent scheduling physical channel transmitted by the second network channel in the first feedback time unit. If the terminal is configured with the type one HARQ-ACK codebook, the fixed-length type one HARQ-ACK codebook does not need to be fed back.

In summary, in the method provided in this embodiment, the terminal receives the first physical channel, the second physical channel and the first control information, so that the terminal can determine whether to feed back the HARQ-ACK information according to the receiving situation of the first physical channel in the received physical channel, thereby ensuring consistency of the network device and the terminal on whether to feed back the HARQ-ACK information.

For the case that the terminal is configured with type three HARQ-ACK codebook feedback, the following embodiments are also provided. Fig. 17 is a flowchart illustrating a feedback method of HARQ-ACK information according to an exemplary embodiment of the present application. The embodiment is applied to the terminal by the method. Alternatively, the terminal is an NTN-enabled terminal. The method comprises the following steps:

step 1702: the terminal receives first control information, wherein the first control information is used for scheduling transmission of a first physical channel, and the first control information carries a first information domain.

Illustratively, the first information field is a one shot HARQ-ACK feedback request information field in DCI format 1_1.

The first information field is used for performing type three HARQ-ACK codebook feedback through a second preset value indication, or the first information field is used for performing no type three HARQ-ACK codebook feedback through a third preset value indication. Illustratively, the second preset value is 1 and the third preset value is 0.

In an exemplary embodiment, when the terminal receives the first physical channel sent by the network device, the terminal determines whether to perform type three HARQ-ACK codebook feedback by determining a value of the first information field in the first control information.

Optionally, the type three HARQ-ACK codebook includes:

HARQ-ACK information corresponding to all downlink HARQ processes on all configured carriers;

Or, the HARQ-ACK information corresponding to all downlink HARQ processes on all activated carriers;

or, the HARQ-ACK information corresponding to the enabled downlink HARQ process on all configured carriers;

or, the HARQ-ACK information corresponding to the enabled downlink HARQ processes on all the activated carriers.

In some embodiments, in the case where the physical channel received in the terminal is any one of the first physical channels, or the received physical channels are all the first physical channels,

the value of the first information field in the first control information is not expected by the terminal to indicate a second preset value, namely, the value of the first information field is not expected by the terminal to indicate 1;

or the terminal expects the value of the first information field in the first control information to indicate a third preset value, namely, the terminal expects the value of the first information field to indicate 0;

or, the terminal does not transmit the HARQ-ACK information.

In some embodiments, the case where the physical channels received by the terminal are all first physical channels (or just first physical channels) includes at least one of the following ways:

the first candidate physical channel receiver groups in the terminal are all received as the first physical channel, and the first candidate physical channel receiver groups correspond to the first feedback time units;

The terminal receives the first physical channel between the two feedback time units.

In some embodiments, the terminal does not expect that the value of the first information field in the first control information indicates the second preset value; or the terminal expects that the value of the first information field in the first control information indicates the third preset value.

In some embodiments, the value of the first information field in the first control information received by the terminal indicates the second preset value.

Optionally, when the value of the first information field in the first control information received by the terminal indicates the second preset value, the terminal performs HARQ-ACK feedback according to the HARQ-ACK codebook of the type three.

In summary, in the method provided in this embodiment, when the terminal is configured with the type three HARQ-ACK codebook feedback, the terminal may determine whether to perform the type three HARQ-ACK codebook feedback according to the value of the feedback request information field in the first control information, so as to ensure consistency of the network device and the terminal with respect to whether to feedback the HARQ-ACK information.

Fig. 18 is a flowchart illustrating a method for receiving a HARQ-ACK codebook according to an exemplary embodiment of the present application. The embodiment is applied to the network equipment by the method. Optionally, the network device is an NTN-enabled network device. The method comprises the following steps:

Step 1802: the network device transmits a first physical channel.

The first physical channel includes a physical channel corresponding to a HARQ process of the first state. The first physical channel corresponds to a first feedback time unit. Illustratively, the first physical channel is a PDSCH, the first physical channel is transmitted in time units n, the first feedback time units being n+k, k being indicated by the network device.

The network device may configure HARQ-ACK codebook feedback for terminal type one or HARQ-ACK codebook feedback for type three.

Optionally, the network device transmits the first physical channel and/or the second physical channel in a first candidate physical channel transmission opportunity set comprising at least one candidate physical channel receiver on at least one serving cell. Each transmission opportunity in the first set of candidate physical channel transmission opportunities corresponds to a first feedback time unit.

HARQ process corresponds to de-enabled state;

HARQ process configured to enable parameters;

HARQ process does not correspond to HARQ-ACK feedback.

Step 1804: and the network equipment determines whether the HARQ-ACK information is received through the first feedback time unit according to the sending condition of the first physical channel.

Optionally, this step includes three possible implementations:

the implementation mode is as follows: the network equipment determines whether to receive the HARQ-ACK information through a first feedback time unit according to the transmission condition of at least one first physical channel;

the transmission of the first physical channel is exemplified by the transmission of the first physical channel in the first candidate physical channel transmission opportunity group.

The implementation mode II is as follows: the network equipment determines distribution indication counting information in at least one piece of control information according to the transmission condition of at least one first physical channel, and determines whether HARQ-ACK information is received through a first feedback time unit;

And the implementation mode is three: the network device determines allocation indication count information in the at least one control information according to the transmission condition of the at least one first physical channel and the transmission condition of the at least one second physical channel, and determines whether to receive the HARQ-ACK information through the first feedback time unit.

The second physical channel corresponds to a HARQ process of a second state.

HARQ process corresponds to enabled state;

HARQ process is not configured to enable parameters;

HARQ process corresponds to HARQ-ACK feedback.
