Description

Technical Field

[0001] The present disclosure relates to the field of wireless communication technologies, and in particular to a method, device, and readable storage medium for determining hybrid automatic repeat request acknowledgment information (HARQ-ACK). Background Art

[0002] To ensure scheduling flexibility, one downlink control information (DCI) can schedule a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH).

[0003] When the sub-carrier spacing (SCS) is 960khz, the corresponding time slot length is 1 / 64ms. When the sub-carrier spacing is large and the time slot length is short, if each PDSCH is scheduled with a separate DCI, the DCI blind detection overhead will be too high. In the multi-TTI (Multi Transmission Time Interval, Multi-TTI) design, one DCI can schedule PDSCH / PUSCH in multiple time slots. Take an example in the multi-TTI PDSCH scheduling scenario to illustrate: one DCI can schedule 4 PDSCHs, and these 4 PDSCHs correspond to 4 consecutive time slots in sequence. These 4 PDSCHs can be used to transmit different data, that is, to transmit different transport blocks (TB). The use of a multi-TTI design can reduce the number of DCIs, thereby reducing the complexity of UE blind detection of DCI. In a multi-TTI PDSCH scheduling scenario, the number of PDSCHs scheduled by a DCI may be semi-statically configured by a higher layer, or may be dynamically indicated by the scheduling DCI after a numerical range is indicated by a protocol or configured by higher layer signaling.

[0004] In a multi-TTI PDSCH scheduling scenario, HARQ-ACKs of multiple PDSCHs need to be fed back on the same PUCCH. Summary of the Invention

[0005] In view of this, embodiments of the present disclosure provide a method, apparatus, and readable storage medium for determining hybrid automatic repeat request acknowledgment information (HARQ-ACK).

[0063] The embodiments of the present disclosure are now further described with reference to the accompanying drawings and specific implementation methods.

[0064] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0065] like Figure 1 As shown, the method for determining hybrid automatic repeat request information provided in the embodiment of the present application can be applied to a wireless communication system 100, which may include a user equipment 101 and a network device 102. The user equipment 101 is configured to support carrier aggregation, and the user equipment 101 can be connected to multiple carrier components of the network device 102, including a primary carrier component and one or more secondary carrier components.

[0066] It should be understood that the above wireless communication system 100 is applicable to both low-frequency scenarios (sub 6G) and high-frequency scenarios (above 6G). Application scenarios of the wireless communication system 100 include, but are not limited to, long-term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, worldwide interoperability for micro wave access (WiMAX) communication systems, cloud radio access networks (CRAN) systems, future fifth-generation (5G) systems, new radio (NR) communication systems, or future evolved public land mobile networks (PLMN) systems.

[0067] The user equipment 101 shown above may be a terminal, an access terminal, a terminal unit, a terminal station, a mobile station (MS), a remote station, a remote terminal, a mobile terminal, a wireless communication device, a terminal agent, or a terminal device, etc. The user equipment 101 may have wireless transceiver functions, and may be capable of communicating (e.g., wireless communication) with one or more network devices of one or more communication systems and receiving network services provided by the network devices, where the network devices include but are not limited to the illustrated network device 102.

[0068] Among them, the user equipment 101 can be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA) device, a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a future 5G network, or a terminal device in a future evolved PLMN network, etc.

[0069] The network device 102 may be an access network device (or access network point). An access network device refers to a device that provides network access functionality, such as a radio access network (RAN) base station. The network device 102 may specifically include a base station (BS), or a base station and a radio resource management device for controlling the base station. The network device 102 may also include a relay station (relay device), an access point, a base station in a future 5G network, a base station in a future evolved PLMN network, or an NR base station. The network device 102 may be a wearable device or an in-vehicle device. The network device 102 may also be a communication chip with a communication module.

[0070] For example, the network device 102 includes but is not limited to: the next generation base station (gnodeB, gNB) in 5G, the evolved node B (eNB) in the LTE system, the radio network controller (RNC), the node B (NB) in the WCDMA system, the wireless controller under the CRAN system, the base station controller (BSC), the base transceiver station (BTS) in the GSM system or the CDMA system, the home base station (for example, home evolved nodeB, or home node B, HNB), the baseband unit (BBU), the transmission point (TRP), the transmitting point (TP) or the mobile switching center, etc.

[0071] In a multi-TTI PDSCH scheduling scenario, the HARQ-ACKs for multiple PDSCHs scheduled by the same DCI should be fed back in the same PUCCH. The user equipment determines the PUCCH time slot for feeding back the HARQ-ACKs for the multiple PDSCHs based on k1 in the DCI and the time slot position of the last PDSCH.

[0072] The size of the Type 2 HARQ-ACK codebook is dynamic. When using DCI to schedule PDSCH, the downlink assignment index (DAI) field in the DCI can be used for counting. DAI includes counter DAI (C-DAI) and total DAI (T-DAI). C-DAI occupies 2 bits and T-DAI occupies 2 bits. When only a single carrier is configured in the user equipment 101, only C-DAI needs to be used. When multiple carriers are configured in the user equipment 101, both C-DAI and T-DAI need to be counted together.

[0073] In the Release 15 / 16 protocol, DCI only schedules a single TB. Therefore, for a UE, if the base station uses multiple DCIs to schedule multiple PDSCHs for feedback on a single PUCCH resource, the C-DAI and T-DAI will increment by 1 for each DCI scheduled by the base station. In this case, the number of DCIs is the same as the number of PDSCHs, and it can be considered that C-DAI and T-DAI are counted according to the number of DCIs or the number of PDSCHs.

[0074] In the multi-TTI PDSCH scheduling scenario, one DCI will schedule multiple PDSCHs. In this case, the number of DCIs and the number of PDSCHs are not equal, so it is necessary to reconsider how C-DAI and T-DAI are counted, and how the type 2 HARQ-ACK codebook is generated.

[0075] If C-DAI and T-DAI are counted according to the number of PDSCHs, since one DCI schedules multiple PDSCHs, the number of bits occupied by C-DAI and T-DAI must be increased, for example, to 4 bits or even 6 bits.

[0076] If C-DAI and T-DAI are counted according to the number of DCIs, in some scheduling scenarios, the number of PDSCHs scheduled by a DCI is dynamically indicated by the DCI rather than semi-statically configured by the higher layer. When one or more DCIs are missed, since the user equipment 101 does not know how many PDSCHs are scheduled by this DCI, the user equipment 101 does not know how many NACKs to feedback for the multiple PDSCHs scheduled by this DCI.

[0077] The present disclosure provides a method for determining HARQ-ACK. Figure 2 , Figure 2 FIG. 1 is a flow chart showing a method for determining HARQ-ACK according to an exemplary embodiment. Figure 2 As shown, this method includes:

[0078] In step S21, in response to a network device scheduling at least one DCI, where each of the at least one DCI schedules more than one physical downlink shared channel (PDSCH), the user equipment 101 determines an index parameter based on the number of the at least one DCI. The user equipment 101 determines a HARQ-ACK codebook corresponding to the at least one DCI based on the index parameter.

[0079] In some embodiments, the index parameter may include at least one of the following parameters: a counting downlink allocation index C-DAI, a total number downlink allocation index T-DAI.

[0080] Step S22: The user equipment 101 sends the HARQ-ACK codebook to the network device 102.

[0081] In step S23 , the network device 102 receives the HARQ-ACK codebook from the user equipment 101 .

[0082] In the embodiments of the present disclosure, the user equipment 101 determines the index parameter (for example, C-DAI and / or T-DAI) according to the number of DCI scheduled by the network equipment, so that the type 2 HARQ-ACK codebook can be accurately fed back without increasing the number of bits occupied by the index parameter, and the coordination of the size of the type 2 HARQ-ACK codebook between the network equipment 102 and the user equipment 101 is ensured.

[0083] In the embodiments of the present disclosure, the above scheme can be applied only to the C-DAI parameter, or only to the T-DAI parameter, or to both the C-DAI and T-DAI parameters. For example, in the case of a single carrier, the above scheme is applied only to the C-DAI parameter, and in the case of a multi-carrier, the above scheme is applied to both the C-DAI and T-DAI parameters.

[0084] The embodiments of the present disclosure provide a method for determining HARQ-ACK, which is executed by the user equipment 101, and the method comprises the following steps:

[0087] In some embodiments, the index parameter can include at least one of the following parameters: a count type downlink allocation index C-DAI, and a total number type downlink allocation index T-DAI.

[0088] In the embodiments of the present disclosure, the user equipment 101 determines the index parameter (for example, C-DAI and / or T-DAI) according to the number of DCI scheduled by the network equipment, so that the type 2 HARQ-ACK codebook can be accurately fed back without increasing the number of bits occupied by the index parameter, and the coordination of the size of the type 2 HARQ-ACK codebook between the network equipment 102 and the user equipment 101 is ensured.

[0089] In the embodiments of the present disclosure, the above scheme may be applied to only the C-DAI parameter, only the T-DAI parameter, or both the C-DAI and T-DAI parameters. Specifically, only the C-DAI parameter may be determined based on the number of DCIs, while the T-DAI parameter may be determined in any possible manner. Alternatively, only the T-DAI parameter may be determined based on the number of DCIs, while the C-DAI parameter may be determined in any possible manner. Alternatively, both the C-DAI and T-DAI parameters may be determined based on the number of DCIs.

[0090] In some possible implementations, the above embodiment further includes: sending the HARQ-ACK codebook to the network device 102.

[0091] The present disclosure provides a method for determining HARQ-ACK, which is performed by user equipment 101 and includes:

[0092] In response to a network device scheduling at least one downlink control information DCI, and each of the at least one DCI schedules more than one physical downlink shared channel PDSCH, an index parameter is determined according to the number of the at least one DCI.

[0095] In some possible implementations, the above embodiment further includes: sending the HARQ-ACK codebook to the network device 102.

[0096] In the embodiment of the present disclosure, the user equipment 101 determines the missed DCI based on the index parameter, and for the missed DCI, determines all HARQ-ACKs in the corresponding HARQ-ACK code as NACK, thereby ensuring that the network device 102 and the user equipment 101 are consistent in the size of the type 2 HARQ-ACK codebook and complying with the processing method of the missed detection scenario.

[0097] In the embodiments of the present disclosure, the above scheme may be applied to only the C-DAI parameter, only the T-DAI parameter, or both the C-DAI and T-DAI parameters. Specifically, only the C-DAI parameter may be determined based on the number of DCIs, while the T-DAI parameter may be determined in any possible manner. Alternatively, only the T-DAI parameter may be determined based on the number of DCIs, while the C-DAI parameter may be determined in any possible manner. Alternatively, both the C-DAI and T-DAI parameters may be determined based on the number of DCIs.

[0189] In some embodiments, the index parameter can include at least one of the following parameters: a count type downlink allocation index C-DAI, and a total number type downlink allocation index T-DAI. In the embodiments of the present disclosure, the above scheme can be applied only to the C-DAI parameter, only to the T-DAI parameter, or to both the C-DAI and T-DAI parameters. That is, only the C-DAI parameter can be determined according to the number of DCIs, while the T-DAI parameter can be determined in any possible manner; only the T-DAI parameter can be determined according to the number of DCIs, while the C-DAI parameter can be determined in any possible manner; or both the C-DAI and T-DAI parameters can be determined according to the number of DCIs.

[0190] In some possible implementation manners, the above embodiments further include: sending the HARQ-ACK codebook to the network device 102.

[0191] In the embodiments of the present disclosure, for the successfully received DCI, the user equipment 101 determines the HARQ-ACK of the successfully received DCI as the demodulation result of the PDSCH scheduled by the successfully received DCI, so that the HARQ-ACK of the successfully received DCI conforms to the actual demodulation result.

[0192] The following is described by way of example through two specific embodiments. Specific Embodiment One

[0194] In a multi-TTI PDSCH scheduling scenario, one DCI schedules N PDSCHs. N is the maximum number of PDSCHs that can be scheduled by a single DCI. N is semi-statically configured by higher layer signaling or is specified by a protocol.

[0195] The value of N is 8. The base station schedules 4 DCIs, namely DCI0, DCI1, DCI2, and DCI3, each of which schedules 8 PDSCHs.

[0196] The C-DAI and T-DAI corresponding to the 4 DCIs are counted according to the number of DCIs, rather than the number of PDSCHs.

[0197] The user equipment 101 generates a HARQ-ACK codebook according to the N, that is, the generated HARQ-ACK codebook includes 32 (i.e., 4*N) HARQ-ACKs, each DCI corresponding to N HARQ-ACKs. The 32 HARQ-ACKs are fed back on one PUCCH channel.

[0198] The user equipment 101 can determine which DCI was missed based on the C-DAI and T-DAI. If the judgment result is that DCI2 was missed, 8 HARQ-ACKs are generated for the 8 PDSCHs corresponding to DCI2, and these 8 HARQ-ACKs are all NACKs.

[0199] For successfully received DCI0, DCI1, and DCI3, the HARQ-ACK of each PDSCH in the eight PDSCHs corresponding to each DCI corresponds to the actual demodulation result of the corresponding PDSCH. Specific embodiment 2

[0201] In a multi-TTI PDSCH scheduling scenario, the maximum number of PDSCHs that can be scheduled by a DCI is configured by higher layer signaling or specified by the protocol. The actual number N of PDSCHs scheduled by a DCI is dynamically indicated by the DCI.

[0202] The maximum number of PDSCHs that can be scheduled by one DCI is 8. The base station schedules four DCIs: DCI0, DCI1, DCI2, and DCI3. DCI0 schedules 6 PDSCHs, DCI1 schedules 6 PDSCHs, DCI2 schedules 4 PDSCHs, and DCI3 schedules 8 PDSCHs.

[0203] The C-DAI and T-DAI corresponding to the four DCIs are counted according to the number of DCIs, rather than the number of PDSCHs.

[0204] The user equipment 101 generates a HARQ-ACK codebook according to N, that is, the generated HARQ-ACK codebook includes 32 (ie, 4*N) HARQ-ACKs, and each DCI corresponds to N HARQ-ACKs. The 32 HARQ-ACKs are fed back on a PUCCH channel.

[0205] The user equipment 101 can determine which DCI was missed based on the C-DAI and T-DAI. If the judgment result is that DCI2 was missed, 8 NACKs are generated for the 6 PDSCHs scheduled by DCI2.

[0206] For the successfully received DCI0, DCI1 and DCI3, the first 6 HARQ-ACKs corresponding to each DCI are determined according to the actual demodulation results of the 6 scheduled PDSCHs. For the 2 HARQ-ACK information that are not scheduled by PDSCH, NACK or ACK can be fed back. Specific embodiment three

[0208] In a multi-TTI PDSCH scheduling scenario, one DCI schedules N PDSCHs. N is the maximum number of PDSCHs that can be scheduled by a single DCI. N is semi-statically configured by higher-layer signaling or specified by the protocol.

[0209] The value of N is 8. The base station schedules 4 DCIs, namely DCI0, DCI1, DCI2 and DCI3, and each DCI schedules 8 PDSCHs.

[0210] The base station configures the second value M through high-layer signaling, or agrees on the second value M through a protocol, where the value of M is 2.

[0211] The C-DAI and T-DAI corresponding to the four DCIs are counted according to the number of DCIs, rather than the number of PDSCHs.

[0212] The user equipment 101 generates a HARQ-ACK codebook according to M, that is, the generated HARQ-ACK codebook includes 8 (ie, 4*M) HARQ-ACKs, and each DCI corresponds to M HARQ-ACKs. The 8 HARQ-ACKs are fed back on a PUCCH channel.

[0213] The user equipment 101 can determine which DCI was missed based on the C-DAI and T-DAI. If the judgment result is that DCI2 was missed, two HARQ-ACKs are generated for the eight PDSCHs corresponding to DCI2, and both of these two HARQ-ACKs are NACKs.

[0214] HARQ-ACK bundling is performed on the successfully received DCI0, DCI1, and DCI3, where each DCI corresponds to 8 PDSCHs. For example, for DCI1, a logical AND process is performed on the HARQ-ACKs of the first 4 PDSCHs among the 8 PDSCHs to obtain a synthesized logical HARQ-ACK, and a logical AND process is performed on the HARQ-ACKs of the last 4 PDSCHs among the 8 PDSCHs to obtain another synthesized logical HARQ-ACK. These two logical HARQ-ACKs are used as the 2 HARQ-ACKs corresponding to DCI1. Specific embodiment 4

[0216] In a multi-TTI PDSCH scheduling scenario, the maximum number of PDSCHs that can be scheduled by a DCI is configured by higher-layer signaling or specified by the protocol. The actual number N of PDSCHs scheduled by a DCI is dynamically indicated by the DCI.

[0217] The maximum number of PDSCHs that can be scheduled by one DCI is 8. The base station schedules four DCIs: DCI0, DCI1, DCI2, and DCI3. DCI0 schedules 6 PDSCHs, DCI1 schedules 6 PDSCHs, DCI2 schedules 4 PDSCHs, and DCI3 schedules 8 PDSCHs.

[0218] The base station configures the second value M through high-layer signaling, or agrees on the second value M through a protocol, where the value of M is 2.

[0219] The C-DAI and T-DAI corresponding to the four DCIs are counted according to the number of DCIs, rather than the number of PDSCHs.

[0220] The user equipment 101 generates a HARQ-ACK codebook according to M, that is, the generated HARQ-ACK codebook includes 8 (ie, 4*M) HARQ-ACKs, and each DCI corresponds to M HARQ-ACKs. The 8 HARQ-ACKs are fed back on a PUCCH channel.

[0221] The user equipment 101 can determine which DCI was missed based on the C-DAI and T-DAI. If the judgment result is that DCI2 was missed, two HARQ-ACKs are generated for the eight PDSCHs corresponding to DCI2, and both of these two HARQ-ACKs are NACKs.

[0222] HARQ-ACK bundling is performed on the successfully received DCI0, DCI1, and DCI3. For example, DCI1 schedules 6 PDSCHs. A logical AND process is performed on the HARQ-ACKs of the first 4 of the 6 PDSCHs to obtain a synthesized logical HARQ-ACK. A logical AND process is performed on the HARQ-ACKs of the last 2 of the 6 PDSCHs to obtain another synthesized logical HARQ-ACK. These two logical HARQ-ACKs are used as the 2 HARQ-ACKs corresponding to DCI1.
