Unlicensed spectrum is a spectrum that can be used for radio equipment communications divided by countries and regions. This spectrum is usually considered to be a shared spectrum, that is, communication devices in different communication systems as long as they meet the regulatory requirements set by the country or region on the spectrum. To use this spectrum, there is no need to apply for a proprietary spectrum authorization from the government.

In order to allow various communication systems that use unlicensed spectrum for wireless communication to coexist friendly on the spectrum, some countries or regions have stipulated the legal requirements that must be met when using unlicensed spectrum. For example, a communication device follows the principle of "Listen Before Talk (LBT)", that is, the communication device needs to perform channel listening before sending signals on channels of unlicensed spectrum. Only when the channel listening result is When the channel is idle, the communication device can send signals; if the channel detection result of the communication device on the channel of the unlicensed spectrum is that the channel is busy, the communication device cannot send signals. In order to ensure fairness, in one transmission, the time that a communication device uses an unlicensed spectrum channel for signal transmission cannot exceed the Maximum Channel Occupancy Time (MCOT).

This application can be applied to unlicensed spectrum or licensed spectrum.

HARQ-ACK feedback in NR-U

When the NR system is applied to the unlicensed frequency band, it can support independent network deployment, that is, it does not rely on the carrier on the licensed frequency band to provide auxiliary services. In this scenario, after the terminal device receives the Physical Downlink Shared Channel (PDSCH) on the unlicensed carrier, it needs to send the HARQ-ACK feedback corresponding to the PDSCH on the unlicensed carrier. The HARQ-ACK feedback information includes ACK information or NACK information, and the HARQ-ACK information may be used to indicate a decoding result of the PDSCH.

On the unlicensed frequency band, the downlink control information DCI for scheduling PDSCH transmission may include HARQ timing indication information (for example, PDSCH-to-HARQ_feedback timing indicator). The HARQ timing indication information can not only be used to determine the time domain position of the HARQ-ACK feedback resource (such as PUCCH resource) for transmitting the HARQ-ACK corresponding to the PDSCH, it may also be used to indicate that the HARQ-ACK information corresponding to the PDSCH is not to be fed back first. status. For example, the pre-configured HARQ timing set includes a non-numerical (NN) K1 (also referred to as invalid K1 or K1 as an invalid value) indicating an invalid resource indication. For example, the value of K1 is negative. 1) When the HARQ timing indication information indicates NNK1 in the HARQ timing set, it indicates that the time domain location of the corresponding HARQ-ACK feedback resource, such as the time slot, cannot be determined temporarily.

In the unlicensed frequency band, in addition to supporting the dynamic codebook (Dynamic or Type 2 (Type 2)) feedback mode of Version 15 (Release 15, R15), it also supports the enhanced dynamic codebook (enhanced Dynamic or enhanced Type 2 or eType 2) feedback Mode and One-shot HARQ-ACK feedback (or Type 3 (Type 3)) codebook feedback mode.

For one-shot HARQ-ACK feedback, the network device can configure one-shot HARQ-ACK feedback for the terminal device, and trigger the terminal device to perform one-shot HARQ-ACK feedback through DCI such as DCI format 1_1. One-shot HARQ-ACK feedback includes HARQ-ACK information feedback corresponding to all HARQ processes on all configured carriers in a Physical Uplink Control Channel (PUCCH) group. If the terminal device is configured with one-shot HARQ-ACK feedback, DCI, for example, DCI format 1_1 may include a one-shot HARQ-ACK feedback request information domain (one-shot HARQ-ACK request). If the terminal device receives the DCI information sent by the network device, and the one-shot HARQ-ACK feedback request information field in the DCI information is a preset value, for example, set to 1, then the terminal device needs to perform one-shot HARQ-ACK feedback. Wherein, the DCI may be downlink grant information, and the DCI may schedule physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) transmission, or may not schedule PDSCH transmission.

The above codebook approach can flexibly feed back the HARQ-ACK information corresponding to the scheduled PDSCH on the unlicensed frequency band.

One-shot HARQ-ACK feedback

In the NR-U system, the network device can configure one-shot HARQ-ACK feedback (also called single HARQ-ACK feedback) for the terminal device, and trigger the terminal device to perform one-shot HARQ-ACK through DCI information such as DCI format 1_1. ACK feedback. During one-shot HARQ-ACK feedback, the HARQ-ACK codebook includes HARQ-ACK information corresponding to all HARQ processes on all configured carriers in a PUCCH group. Specifically, it can include two types. Type 1 is one-shot HARQ-ACK feedback that carries New Data Indicator (NDI), and type 2 is one-shot HARQ-ACK feedback that does not carry NDI. Network equipment can use wireless Resource control (Radio Resource Control, RRC) signaling is used to configure whether terminal equipment needs to carry NDI information when performing HARQ-ACK feedback.

It should be noted that in some scenarios, the carrier and the cell can be the same concept, or the carrier can also be replaced with the cell.

In one-shot HARQ-ACK feedback, for code block group (Code block group, CBG) transmission is configured (for example, the terminal device is provided with the signaling of the maximum code block group (maxCodeBlockGroupsPerTransportBlock) information included in each transmission block) ) Carrier, the network device can use RRC signaling (for example, pdsch-HARQ-ACK-OneShotFeedbackCBG-r16) to instruct the terminal device whether to perform CBG feedback when performing one-shot HARQ-ACK feedback. If the terminal device is configured with CBG-based feedback on a certain carrier, the terminal device needs to perform CBG-based feedback when performing one-shot HARQ-ACK feedback of the carrier.

As an example, taking the HARQ scheduling process shown in FIG. 2 as an example, the type 1 and type 2 one-shot HARQ-ACK feedback will be described. Assume that the terminal device is configured with two component carriers (Component Carrier, CC), which are respectively denoted as CC1 and CC2. Both CC1 and CC2 are based on transport block (TB) feedback, and one HARQ process on CC1 and CC2 corresponds to 1-bit HARQ-ACK information. As shown in Figure 2, on time slot n, the terminal device receives the PDSCH 1 scheduled by DCI 1 through HARQ 4 on CC1, K1=3, single time=0 (that is, one-shot HARQ-ACK feedback is not triggered), NDI=1; the terminal device receives the PDSCH 2 scheduled by DCI 2 through HARQ 5 on CC2, K1=3, single=0, NDI=0. On time slot n+1, the terminal device receives PDSCH 3 scheduled by DCI 3 through HARQ 8 on CC1, K1=2, single=0, NDI=0. On time slot n+2, the terminal device receives PDSCH 4 scheduled by DCI 4 through HARQ 9 on CC2, K1=1, single=1 (that is, one-shot HARQ-ACK feedback is triggered), and NDI=1. In particular, one-shot type 1 HARQ-ACK feedback codebook can shown in FIG. 2 A, a PDSCH feedback for HARQ-ACK feedback NDI 1 and located on 9 bits (bits 9 ^TH) and 10 bits ( 10 ^th bit), the HARQ-ACK feedback and NDI feedback for PDSCH 3 are located on the 17th bit (17 ^th bit) and the 18th bit (18 ^th bit), and the HARQ-ACK feedback and NDI feedback for PDSCH 2 are located on the 43rd bit (43 ^th bit) and 44 ^th bit (44 th bit), the HARQ-ACK feedback and NDI feedback for PDSCH 4 are located at the 51 ^th bit (51 th bit) and the 52 ^th bit (52 th bit). In particular, one-shot type-2 HARQ-ACK feedback codebook B shown in FIG. 2 may be, for HARQ-ACK PDSCH 1 5 located on the feedback bits (bits 5 ^TH) for the HARQ-ACK PDSCH 3 feedback on page 9 bits (bits 9 ^TH), for HARQ-ACK PDSCH 2 located on the 22 feedback bits (22 bits ^TH), for HARQ-ACK PDSCH 4 26 located on the feedback bits (26 bits ^TH). After the terminal device generates the one-shot HARQ-ACK codebook according to the type 1 or type 2 HARQ-ACK codebook generation method, it can transmit the one-shot HARQ-ACK codebook through PUCCH resource 1 in time slot n+3 .

It should be understood that in Figure 2 above, single = 0 means that the one-shot HARQ-ACK feedback request information field in the DCI format is set to 0, which means that one-shot feedback is not triggered, and single = 1 means that the one-shot feedback is not triggered. The one-shot HARQ-ACK feedback request information field is set to 1, which means that one-shot feedback is triggered. In addition, K1 represents HARQ timing indication information. For example, if a terminal device receives a PDSCH 1 scheduled by DCI 1 through HARQ 4 on time slot n, and K1=3, then the terminal device feeds back the corresponding HARQ- on time slot n+3. ACK information.

Sleeping or non-sleeping behavior indication of secondary cell

In the evolved system of the NR system, the DCI format is introduced to indicate the dormancy or non-dormancy (Scell dormancy/non-dormancy, or called dormancy or de-dormancy) behavior of the secondary cell. Specifically, if the DCI format 1_1 is not used to schedule PDSCH reception, then the existing part of the information field in the DCI format 1_1 can be used to indicate the dormancy or non-sleep of the secondary cell, where the existing part of the information field may include the first code At least one of Modulation and Coding Scheme (MCS) of the word, NDI of the first codeword, Redundancy Version (RV) of the first codeword, HARQ process number, antenna port field, etc. If the DCI format 1_1 is not used for scheduling PDSCH reception, it may include the frequency domain resource assignment (FDRA) in the DCI format 1_1 indicating all 0s or all 1s.

As an example, if the terminal device is configured to monitor DCI format 1_1, and

If the terminal device receives the DCI format 1_1 using the Cell Radio Network Temporary Identity (C-RNTI) or MCS-C-RNTI scrambling code, and

If the DCI format 1_1 does not include the one-shot HARQ-ACK feedback request information field or the one-shot HARQ-ACK feedback request information field included in the DCI format 1_1 does not trigger the one-shot HARQ-ACK feedback, for example, the feedback request information The domain is set to "0", and

If the resource allocation mode is Type 0, the bits of all FDRA fields included in the DCI format 1_1 are set to 0, or,

If the resource allocation mode is Type 1, the bits of all FDRA fields included in the DCI format 1_1 are set to 1, or,

If the resource allocation mode is dynamic switching, the bits of all FDRA fields included in the DCI format 1_1 are set to 0 or 1,

Then the terminal device considers that the bits in the partial information field in the DCI format 1_1 are used to indicate the dormancy or non-sleep of the secondary cell, and the DCI format 1_1 is not used to schedule PDSCH reception or not to indicate semi-persistent scheduling physical downlink shared channel (Semi- Persistent Scheduling Physical Downlink Shared Channel, SPS PDSCH) release.

It should be noted that if the DCI format 1_1 is used to indicate the dormant or non-sleep behavior of the secondary cell, and the DCI format 1_1 is not used to schedule PDSCH reception or not used to indicate SPS PDSCH release, when the terminal device is configured to perform according to the type-2 codebook When giving feedback, the terminal device needs to include the Acknowledgement (ACK) information corresponding to the DCI format 1_1 in the type-2 codebook, and the ACK information may be used to indicate that the terminal device correctly receives the DCI format 1_1.

In the NR-U system, if the DCI format is used to indicate the dormant or non-dormant behavior of the secondary cell, when the terminal device is configured with one-shot HARQ-ACK feedback (for example, the terminal device is configured with pdsch-HARQ-ACK-OneShotFeedback-r16) At this time, how to process the ACK information corresponding to the DCI format indicating the dormant or non-dormant behavior of the secondary cell, for example, the ACK information corresponding to the DCI format 1_1, has not yet been discussed.

Based on the above problems, this application proposes a HARQ-ACK codebook feedback scheme. The terminal device can simultaneously carry feedback information corresponding to the DCI format used to indicate the dormant or non-dormant behavior of the secondary cell in a HARQ-ACK codebook. And the feedback information based on HARQ process number arrangement on N cells, thereby optimizing the communication on the shared spectrum.

Optionally, in the embodiment of the present application, the number of HARQ processes included in a cell may be configured by the network equipment, or, if the network equipment is not configured, the number of HARQ processes included in a cell may be a default value, for example, the default value is 8.

Optionally, in this embodiment of the present application, the N cells include all cells configured in a PUCCH group; or, the N cells include all cells activated in a PUCCH group.

Optionally, the first PDCCH includes the first DCI format (DCI format 1_1), or the first DCI format is transmitted through the first PDCCH, and the bits in the part of the information field in the DCI in the first PDCCH are used to indicate that the secondary cell is dormant or It is not dormant, and the first PDCCH or the DCI format 1_1 is not used for scheduling PDSCH reception or not used for indicating SPS PDSCH release.

Optionally, in the embodiment of the present application, the terminal device generates the first HARQ-ACK codebook for the first time unit according to the received second DCI format, where the second DCI format includes a single HARQ-ACK Feedback request information, and HARQ timing indication information included in the second DCI format indicates the first time unit. Alternatively, the first HARQ-ACK codebook is generated by the terminal device for the first time unit based on a second DCI format, where the second DCI format includes single HARQ-ACK feedback request information, and the second DCI format The HARQ timing indication information included in the, indicates the first time unit.

In other words, the foregoing step S230 may specifically be: the terminal device generates the first HARQ-ACK codebook for the first time unit according to the received second DCI format, where the second DCI format includes a single HARQ-ACK codebook. Feedback request information, and HARQ timing indication information included in the second DCI format indicates the first time unit.

For example, the terminal device receives the second DCI format sent by the network device. That is, the second DCI format may be sent by the network device.

It should be noted that the inclusion of the single HARQ-ACK feedback request information in the second DCI format can be understood as: the single HARQ-ACK feedback request information field included in the second DCI format indicates "1", for example, single (one -shot)=1. The second DCI format does not include the single HARQ-ACK feedback request information can be understood as: the single HARQ-ACK feedback request information field included in the second DCI format indicates "0", for example, single (one-shot) = 0, or, the second DCI format does not include the single HARQ-ACK feedback request information field.

Optionally, in some embodiments, in the case where the HARQ timing indication information included in the second DCI format indicates the first time unit, the HARQ timing indication information included in the first DCI format also indicates the first time unit. Time unit. That is to say, the HARQ timing indication information included in the first DCI format and the HARQ timing indication information included in the second DCI format both indicate the first time unit. In this case, the same uplink feedback resource is required, for example The first HARQ-ACK codebook generated by the PUCCH resource includes two kinds of HARQ-ACK information (the feedback bit sequence and the first bit sequence arranged based on the HARQ process number on the N cells). The terminal device may generate the first HARQ-ACK codebook for the first time unit.

Optionally, in other embodiments, in the case that the HARQ timing indication information included in the second DCI format indicates the first time unit, the HARQ timing indication information included in the first DCI format may indicate an invalid value The second DCI format is a DCI format detected on a physical downlink control channel (Physical Downlink Control Channel, PDCCH) monitoring opportunity after the first DCI format. That is, in the case where the HARQ timing indication information included in the first DCI format indicates an invalid value, if the second DCI format is received after the first DCI format is received, the HARQ included in the second DCI format The timing indication information indicates the first time unit. In this case, the first HARQ-ACK codebook generated for the uplink feedback resources on the first time unit, such as PUCCH resources, may include two types of HARQ-ACK information (N cells The feedback bit sequence and the first bit sequence arranged based on the HARQ process number above). The terminal device may generate the first HARQ-ACK codebook for the first time unit.

Optionally, in some embodiments, in the case where the HARQ timing indication information included in the second DCI format indicates the first time unit, the first DCI format does not include HARQ timing indication information and the higher layer configuration parameter indicates The feedback time unit corresponding to the first DCI format includes the first time unit. That is, the feedback time unit corresponding to the first DCI format and the feedback time unit indicated by the HARQ timing indication information included in the second DCI format both include the first time unit. In this case, the same uplink time unit is required. The feedback resource, such as the first HARQ-ACK codebook generated by the PUCCH resource, includes two kinds of HARQ-ACK information (the feedback bit sequence and the first bit sequence arranged based on the HARQ process number on the N cells). The terminal device may generate the first HARQ-ACK codebook for the first time unit.

Optionally, in some implementation manners, if the first time unit is used to feed back the first bit sequence and the feedback bit sequence arranged based on the HARQ process number on the N cells, for example, the HARQ timing indication information included in the first DCI format Indicate the first time unit, the second DCI format includes single HARQ-ACK feedback request information, and the HARQ timing indication information included in the second DCI format also indicates the first time unit. In this case, when the terminal device generates the first HARQ-ACK codebook for the first time unit, the first HARQ-ACK codebook may include the feedback bit sequence arranged based on the HARQ process number on the N cells but does not include the first HARQ-ACK codebook. A sequence of bits. In this manner, it can be considered that the priority of the feedback bit sequence arranged based on the HARQ process number on the N cells is higher than the priority of the first bit sequence, so that the first bit sequence is not fed back in the first time unit.

Optionally, in some embodiments, when the feedback time unit corresponding to the first DCI format and the feedback time unit corresponding to the second DCI format both include the first time unit, the terminal device passes through the first uplink on the first time unit. The resource, for example, PUCCH 1 sends the first bit sequence, and the second uplink resource on the first time unit, for example, PUCCH 2, sends feedback bit sequences arranged based on HARQ process numbers on N cells. Wherein, optionally, at least one of PUCCH 1 and PUCCH 2 is a short PUCCH. Optionally, PUCCH 1 and PUCCH 2 do not overlap in the time domain.

Optionally, in the embodiment of the present application, if the first HARQ-ACK codebook includes the feedback bit sequence and the first bit sequence arranged based on HARQ process numbers on N cells. In this case, in the first HARQ-ACK codebook, the feedback bit sequence and the first bit sequence arranged based on the HARQ process number on the N cells may include the multiple arrangements described in Examples 1 to 3 below At least one of.

Example 1: The feedback bit sequence arranged based on the HARQ process number on the N cells includes the first bit sequence.

Optionally, in Example 1, the first DCI format includes indication information of the first HARQ process number, and the position of the first bit sequence in the feedback bit sequence arranged based on the HARQ process number on the N cells is based on The index of the first cell and/or the first HARQ process number is determined.

Optionally, in Example 1, if the first cell corresponds to a transport block (TB)-based feedback mode, the first bit sequence includes 1-bit ACK information.

Optionally, the length of the first bit sequence is determined according to the TB feedback length (for example, the TB feedback length may be determined according to the high-level configuration parameter maxNrofCodeWordsScheduledByDCI). The 1-bit ACK information corresponds to the feedback information position of the first codeword. For example, if the TB feedback length is 2, then the first bit in the first bit sequence is the ACK information, and the second bit is the NACK space.

Optionally, in Example 1, if the first cell corresponds to a code block group (CBG) feedback mode, the first bit sequence includes 1-bit ACK information or the first bit sequence includes G-bit ACK Information, where G represents the CBG feedback length corresponding to a TB on the first cell (for example, the CBG feedback length can be determined according to the high-level configuration parameter maxCodeBlockGroupsPerTransportBlock), and the G is a positive integer.

Optionally, the CBG-based feedback mode corresponding to the first cell includes a situation in which the first cell is configured for CBG transmission and the first cell is configured for CBG feedback.

Optionally, in Example 1, if the first cell corresponds to a CBG feedback mode, the first bit sequence length is determined according to the TB feedback length and the CBG feedback length. The ACK information corresponding to the first DCI format corresponds to the feedback information position of the first codeword. For example, assuming that the TB feedback length is 2 and the CBG feedback length is 4, then the first bit sequence includes at least 2*4=8 bits. For example, if the first bit sequence includes 1-bit ACK information, the first bit sequence may include [ACK NACK NACK NACK NACK NACK NACK NACK NACK]; or if the first bit sequence includes G bits of ACK information, the first bit sequence may include G bits of ACK information. The bit sequence may include [ACK ACK ACK ACK NACK NACK NACK NACK].

Optionally, in Example 1, if the terminal device is configured to include a feedback manner of New Data Indicator (NDI) information, the NDI information included in the first bit sequence is a preset value. For example, the NDI information included in the first bit sequence is set to 0. This is mainly considering that when data is not scheduled, the NDI indication information is used to indicate the dormant or non-dormant behavior of the secondary cell, so here it is more inclined to feed back the preset value instead of feeding back according to the indication information. For example, assuming that the first cell corresponds to a TB-based feedback mode, and the TB feedback length is 2, then the first bit sequence includes [ACK NACK 0 0].

Optionally, in Example 1, if the terminal device is configured to include a feedback mode of NDI information, the NDI information included in the first bit sequence is determined according to the NDI indication information in the first DCI format.

In either of the above two situations, the network device can determine the first bit sequence of the NDI information and the ACK information corresponding to the first DCI format that the terminal device should feed back, so as not to cause ambiguity in understanding.

Optionally, the terminal device being configured to include the feedback mode of the NDI information may include: the network device configures the terminal device with a one-shot HARQ-ACK feedback mode including the NDI information.
