Description

Technical Field

[0001] The present disclosure relates to the field of communication technologies, and in particular, to a method for determining a HARQ codebook, a method for receiving HARQ feedback information, and an apparatus therefor. Background Art

[0002] In a Hybrid Automatic Repeat Request (HARQ) mechanism, multiple parallel HARQ processes are supported for transmission, that is, a transmitting end can initiate multiple Physical Downlink Shared Channel (PDSCH) transmissions in parallel.

[0003] In the scenario of satellite communication, in order to avoid large delays caused by the propagation distance, the HARQ mechanism supports HARQ processes that are not enabled (disabled), that is to say, some HARQ processes can be configured not to perform HARQ feedback. However, the current HARQ semi-static codebook is for HARQ processes that are only enabled in the HARQ mechanism; for the case of HARQ processes that are not enabled in the HARQ mechanism, there is currently a lack of a corresponding HARQ semi-static codebook determination scheme.

[0064] Embodiments of the present disclosure will be described in detail below.

The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present disclosure, and should not be construed as a limitation to the present disclosure.

[0065] For ease of understanding, the terms related to the present disclosure will be introduced first.

[0066] 1. NTN refers to Non-Terrestrial Network communication.

[0067] NTN communication, especially satellite communication, has been included in the discussions of the 3GPP (Third Generation Partnership Project) regarding the 5G (5th Generation) standard because of its characteristics of wide coverage, strong disaster resistance ability, and large capacity. In the 3GPP research project "5GNR (New Radio) in 'Non-Terrestrial Networks'", the TR38.811 (Rel-15) report studied the deployment scenarios of NTN networks and the channel models of NTN networks, and the TR38.821 (Rel-16) report studied the NG-RAN (Next Generation-Radio Access Network) architecture based on NTN, and defined and evaluated the solutions for the network architecture of the integration of NTN networks and 5G networks.

[0068] NTN can be used as a supplement to terrestrial networks (such as 5G networks) to provide continuous services for M2M (Machine-to-Machine) / IoT (Internet Of Things) devices and mobile platform users. For example, for areas where terrestrial networks cannot cover or the coverage cost is high, such as at sea or on high-speed rails, the communication problems in these areas can be solved through NTN, enhancing the reliability of 5G networks, or by directly providing broadcast or multicast services to user equipment at the network edge, enhancing the scalability of 5G networks; it can also operate independently to provide the only service for remote areas, islands, etc., making network services ubiquitous.

[0069] Whether it is NTN with satellite-terrestrial integration or standalone NTN, compared with typical 5G networks, it will have a greater impact on performance such as coverage, user bandwidth, system capacity, service reliability or service availability, energy consumption, and connection density. It can provide users with a more reliable and consistent service experience, reduce the network deployment cost of operators, connect the multi-dimensional spaces of air, space, land, and sea, and form an integrated ubiquitous network pattern.

[0070] Compared with terrestrial networks, NTN networks have the characteristic of large transmission delay due to the long distance between the communicating parties. For example, in scenario A based on GEO (Geostationary Earth Orbit) in TR38.821, the RTT (RoundTrip Time, maximum round-trip delay) reaches 541.46 milliseconds; in scenario C based on LEO (Low Earth Orbit), when the orbital altitude of the LEO satellite is 600 kilometers, the maximum RTT is 25.77 milliseconds.

[0071] 2. HARQ refers to Hybrid Automatic Repeat Request.

[0072] The HARQ mechanism is one of the most important functions in NR. Combined with link adaptation, HARQ can achieve efficient, reliable, and low-latency data transmission in cellular networks.

[0073] As Figure 1 shown, when using the HARQ protocol, the sending end (i.e., the network device) needs to wait for the feedback from the receiving end (i.e., the terminal device) before sending new data (PDSCH). If the feedback from the receiving end is NACK (Negative Acknowledgement), the sending end needs to retransmit the data packet. Otherwise, if the feedback from the receiving end is ACK (Acknowledgement), the sending end may send new data. The SAW (Stop-And-Wait) process in the HARQ mechanism will reduce the link throughput due to the HARQ RTT delay. To solve this problem, the HARQ mechanism supports the transmission of multiple parallel HARQ processes. That is, the sending end can initiate multiple PDSCH transmissions in parallel without waiting for the completion of HARQ.

[0074] Among them, Figure 1 the slot in it refers to a time slot, and the TB is a Transport Block.

[0075] Currently, the overall information fed back by a terminal device on a HARQ feedback resource is referred to as a HARQ codebook. In NR, multiple HARQ codebook designs are supported, including semi-static codebooks and dynamic codebooks. Among them, a semi-static codebook refers to a HARQ codebook whose size does not change dynamically according to the actual data scheduling situation. The size of the HARQ codebook is predefined or preconfigured, that is, the size of the codebook fed back by the terminal device on each HARQ feedback resource is determined; a dynamic codebook means that the size of the HARQ codebook is dynamically determined based on the actual data scheduling situation.

[0076] Among them, the HARQ feedback resource refers to the time-frequency resource occupied by HARQ information transmission.

[0077] In the related art, in the satellite communication scenario, in order to avoid large delays caused by the propagation distance, the HARQ mechanism supports HARQ processes that are not enabled. That is to say, the network device can configure certain HARQ processes of the terminal device not to perform HARQ feedback. However, the current HARQ semi-static codebook is for HARQ processes that only support enabled HARQ in the HARQ mechanism; for the case of HARQ processes that support non-enabled HARQ in the HARQ mechanism, that is, when the PDSCH that the terminal device needs to feed back on a certain HARQ feedback resource is configured as non-enabled HARQ, it is necessary to clarify how the terminal device determines the feedback codebook.

[0078] In view of the above problems, the present disclosure provides a method for determining a HARQ codebook, a method for receiving HARQ feedback information, and their devices.

[0079] Figure 2 It is a schematic flowchart of a method for determining a HARQ codebook provided by an embodiment of the present disclosure. This method for determining a HARQ codebook can be applied to a terminal device.

[0080] Among them, the terminal device can be a device that provides voice and / or data connectivity to the user, such as a handheld device with wireless connection function, or other processing devices connected to a wireless modem. In different systems, the name of the terminal device may also be different. For example, in a 5G system, the terminal device can be called a UE (User Equipment). Among them, the wireless terminal device can communicate with one or more CNs (Core Network) via the RAN (Radio Access Network). The wireless terminal device can be a mobile terminal device, such as a mobile phone (or called a "cellular" phone) and a computer with a mobile terminal device. For example, it can be a portable, pocket-sized, handheld, computer-integrated or vehicle-mounted mobile device, which exchanges language and / or data with the wireless access network.

[0081] For example, the terminal device can be a PCS (Personal Communication Service) phone, a cordless phone, a SIP (Session Initiated Protocol) phone, a WLL (Wireless Local Loop) station, a PDA (Personal Digital Assistant), etc. The wireless terminal device can also be called a system, a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, a user device, which is not limited in the embodiments of the present disclosure.

[0082] As Figure 2 shown, the method for determining the HARQ codebook may include the following steps:

[0083] Step 201, determine the HARQ codebook corresponding to the HARQ feedback resource according to the HARQ enabling types of multiple PDSCH transmissions targeted on the specified HARQ feedback resource.

[0084] In an embodiment of the present disclosure, a designated HARQ feedback resource refers to a time-frequency resource for transmitting HARQ feedback information, that is, the HARQ feedback information carried in the HARQ codebook is transmitted on the HARQ feedback resource. Among them, the HARQ feedback information may be HARQ feedback for one or more PDSCH transmissions.

[0085] It can be understood that for multiple PDSCH transmissions, the HARQ feedback resource for transmitting HARQ feedback information can be determined according to the time slot where the PDSCH transmission is located, the indication of the scheduling instruction, etc.

[0086] In an embodiment of the present disclosure, the HARQ enabling type may include at least one of the following: enabling HARQ; disabling HARQ.

[0087] It should be understood that in the related art, the HARQ codebook is directly determined without considering the HARQ enabling type, which is difficult to apply to the case where HARQ is disabled. If the HARQ codebook determined by the above method directly specifies the feedback behavior of the terminal device, errors may occur. However, in the embodiment of the present disclosure, the terminal device determines the HARQ codebook corresponding to the HARQ feedback resource according to the HARQ enabling type for multiple PDSCH transmissions transmitted on the designated HARQ feedback resource, which can be applied to the scenario where HARQ is disabled and can standardize the HARQ feedback behavior of the terminal device.

[0088] The method for determining the HARQ codebook in the embodiment of the present disclosure enables the terminal device to determine the HARQ codebook corresponding to the HARQ feedback resource according to the HARQ enabling type for multiple PDSCH transmissions transmitted on the designated HARQ feedback resource. Thus, the terminal device combines the HARQ enabling type of multiple PDSCH transmissions to determine the HARQ codebook corresponding to the HARQ feedback resource, which can be applied to the scenario where HARQ is disabled and standardize the HARQ feedback behavior of the terminal device.

[0089] The embodiment of the present disclosure provides another method for determining the HARQ codebook. Figure 3 It is a schematic flowchart of another method for determining the HARQ codebook provided by the embodiment of the present disclosure. This method for determining the HARQ codebook can be applied to a terminal device. This method for determining the HARQ codebook can be executed alone, or can be executed in combination with any one embodiment or possible implementation manner in the present disclosure, or can also be executed in combination with any one technical solution in the related art.

[0090] As Figure 3 shown, this method for determining the HARQ codebook may include the following steps:

[0091] Step 301: In response to the HARQ enabling types of multiple PDSCH transmissions targeted on a specified HARQ feedback resource all being HARQ enabled, determine, according to the results of the multiple PDSCH transmissions, the HARQ feedback information corresponding to the multiple PDSCH transmissions in the HARQ codebook corresponding to the HARQ feedback resource.

[0092] It should be noted that the explanations of the HARQ feedback resource in the foregoing embodiments also apply to this embodiment and will not be elaborated herein.

[0093] In the embodiments of the present disclosure, when the HARQ enabling types of multiple PDSCH transmissions targeted on a specified HARQ feedback resource are all enabled HARQ, the terminal device may determine, according to the results of the multiple PDSCH transmissions, the HARQ feedback information corresponding to the multiple PDSCH transmissions in the HARQ codebook corresponding to the HARQ feedback resource.

[0094] For example, referring to Figure 4 , taking a specified HARQ feedback resource as a certain UL (Uplink) time-frequency resource (slot), such as UL slot7, for exemplary illustration. Assume that the enabling types of PDSCH transmissions scheduled by the network device in DL (Downlink) slots 0, 1, 2, and 3 are all enabled HARQ. And assume that for the PDSCH transmissions scheduled in DL slots 0 and 1, the terminal device correctly receives them, and for the PDSCH transmissions scheduled in DL slots 2 and 3, the terminal device fails to receive them. Then the terminal device may determine that in the HARQ codebook corresponding to the HARQ feedback resource, the HARQ feedback information corresponding to the PDSCH transmissions scheduled in DL slots 0 and 1 is an acknowledgement message (that is, the HARQ feedback information corresponding to the PDSCH transmissions scheduled in DL slots 0 and 1 is ACK and ACK respectively), and the HARQ feedback information corresponding to the PDSCH transmissions scheduled in DL slots 2 and 3 is a negative acknowledgement message (that is, the HARQ feedback information corresponding to the PDSCH transmissions scheduled in DL slots 2 and 3 is NACK and NACK respectively).

[0095] Among them, the network device is taken as a base station as an example. The base station may include multiple cells that provide services for terminal devices. According to different specific application scenarios, each cell may further include multiple TRPs (Transmission Reception Point or Transmit / Receive Point, transmission and reception points), and each TRP may include one or more antenna panels, or may be a device that communicates with a wireless terminal device through one or more sectors on the air interface in the access network, or other names. For example, the base station involved in the embodiments of the present disclosure may be a BTS (Base Transceiver Station) in GSM (Global System for Mobilecommunications) or CDMA (Code Division Multiple Access), or may be a base station (NodeB) in WCDMA (Wide-band Code Division Multiple Access), or may also be an evolved Node B (abbreviated as eNB or e-NodeB) in an LTE (long term evolution) system, a 5G base station (abbreviated as gNB) in a 5G network architecture (next generation system), or may also be a HeNB (Home evolved Node B), a relay node, a femto, a pico, etc. The embodiments of the present disclosure do not limit this.

[0096] That is to say, in the present disclosure, when the HARQ processes included in the HARQ codebook at the time of feedback to be sent are all HARQ enabled HARQ processes, for the HARQ feedback information that needs to be sent on the current HARQ feedback resource, the terminal device may determine the HARQ feedback information corresponding to multiple PDSCH transmissions according to the actual reception conditions of the multiple PDSCH transmissions.

[0097] The method for determining the HARQ codebook according to the embodiments of the present disclosure enables the terminal device to determine the HARQ codebook corresponding to the HARQ feedback resource according to the HARQ enabling types of multiple PDSCH transmissions transmitted on the specified HARQ feedback resource. Thus, the terminal device combines the HARQ enabling types of multiple PDSCH transmissions to determine the HARQ codebook corresponding to the HARQ feedback resource, which can be applied to scenarios where HARQ is not enabled, and standardizes the HARQ feedback behavior of the terminal device.

[0098] It should be noted that the above possible implementation manners can be executed independently or in combination, and the embodiments of the present disclosure do not limit this.

[0099] The embodiments of the present disclosure provide another method for determining a HARQ codebook. Figure 5 FIG. is a schematic flowchart of another method for determining a HARQ codebook provided by the embodiments of the present disclosure. The method for determining a HARQ codebook can be applied to a terminal device. The method for determining a HARQ codebook can be executed independently, or can be executed in combination with any one of the embodiments or possible implementation manners in the present disclosure, or can also be executed in combination with any one of the technical solutions in the related art.

[0100] As Figure 5 shown, the method for determining a HARQ codebook may include the following steps:

[0101] Step 501, in response to that the HARQ enabling types for multiple PDSCH transmissions on a specified HARQ feedback resource are all HARQ disabled, determine that the HARQ codebook corresponding to the HARQ feedback resource is empty.

[0102] It should be noted that the explanation of the HARQ feedback resource in the foregoing embodiments also applies to this embodiment and will not be repeated here.

[0103] In the embodiments of the present disclosure, when the HARQ enabling types for multiple PDSCH transmissions on a specified HARQ feedback resource are all HARQ disabled, the terminal device can determine that the HARQ codebook corresponding to the HARQ feedback resource is empty, that is, the terminal device can abandon the HARQ feedback for the above multiple PDSCH transmissions.

[0104] As an example, when all the HARQ processes included in the HARQ codebook at the time to be feedback are HARQ disabled HARQ processes, for the HARQ feedback information that needs to be feedback on this HARQ feedback resource, the terminal device can abandon the transmission of this HARQ feedback resource. As Figure 6 shown, taking the specified HARQ feedback resource as UL slot7 for exemplary illustration, when the enabling types of the PDSCH transmissions scheduled by DL slot0, 1, 2, 3 are all HARQ disabled, regardless of whether the PDSCH transmissions scheduled on DL slot0, 1, 2, 3 are correctly received or received failed by the terminal device, the terminal device does not transmit HARQ feedback information on this UL slot7.

[0105] The method for determining a HARQ codebook according to an embodiment of the present disclosure enables a terminal device to determine a HARQ codebook corresponding to a HARQ feedback resource based on the HARQ enabling types for multiple PDSCH transmissions performed on a specified HARQ feedback resource. Thereby, the terminal device determines the HARQ codebook corresponding to the HARQ feedback resource by combining the HARQ enabling types for multiple PDSCH transmissions, which can be applicable to scenarios where HARQ is not enabled and standardize the HARQ feedback behavior of the terminal device.

[0106] It should be noted that the above possible implementation manners can be executed independently or in combination, and the embodiments of the present disclosure do not make any limitations thereto.

[0107] An embodiment of the present disclosure provides another method for determining a HARQ codebook. Figure 7 FIG. [8] is a flowchart of another method for determining a HARQ codebook provided by an embodiment of the present disclosure. The method for determining a HARQ codebook can be applied to a terminal device. The method for determining a HARQ codebook can be executed independently, or can be executed in combination with any one of the embodiments or possible implementation manners in the present disclosure, or can also be executed in combination with any one of the technical solutions in the related art.

[0108] As Figure 7 shown, the method for determining a HARQ codebook may include the following steps:

[0109] Step 701, in response to the HARQ enabling types for multiple PDSCH transmissions performed on a specified HARQ feedback resource all being HARQ not enabled, determining that the HARQ feedback information corresponding to the multiple PDSCH transmissions in the HARQ codebook corresponding to the HARQ feedback resource is negative acknowledgment information.

[0110] It should be noted that the explanation of the HARQ feedback resource in the foregoing embodiment also applies to this embodiment and will not be elaborated herein.

[0111] In an embodiment of the present disclosure, when the HARQ enabling types for multiple PDSCH transmissions performed on a specified HARQ feedback resource are all HARQ not enabled (disabled), the terminal device may determine that the HARQ feedback information corresponding to the multiple PDSCH transmissions in the HARQ codebook corresponding to the HARQ feedback resource is negative acknowledgment information (NACK).

[0112] For example, referring to Figure 8 It should be noted that there seems to be a missing number in the reference in the original text in line . I have translated it as "FIG. [8]" for the sake of consistency with the format. You may need to check and correct it according to the actual situation., an exemplary description is given with the specified HARQ feedback resource being UL slot 7. Assume that the enabling types of the PDSCH transmissions scheduled in DL slots 0, 1, 2, and 3 are all HARQ disabled, and assume that for the PDSCH transmissions scheduled in DL slots 0 and 1, the terminal device correctly receives them, while for the PDSCH transmissions scheduled in DL slots 2 and 3, the terminal device fails to receive them. Since the HARQ enabling types of multiple PDSCH transmissions are all HARQ disabled, therefore, regardless of the data reception situation, the HARQ feedback information for the 4 PDSCH transmissions by the terminal device is NACK, that is, the HARQ feedback information corresponding to the PDSCH transmissions scheduled in DL slots 0, 1, 2, and 3 is NACK, NACK, NACK, and NACK respectively.

[0113] The method for determining the HARQ codebook according to the embodiments of the present disclosure enables the terminal device to determine the HARQ codebook corresponding to the HARQ feedback resource based on the HARQ enabling types of multiple PDSCH transmissions targeted on the specified HARQ feedback resource. Thus, the terminal device combines the HARQ enabling types of multiple PDSCH transmissions to determine the HARQ codebook corresponding to the HARQ feedback resource, which can be applied to the scenario where HARQ is disabled and standardize the HARQ feedback behavior of the terminal device.

[0114] It should be noted that these possible implementation manners described above can be executed independently or in combination, and the embodiments of the present disclosure do not make any limitations in this regard.

[0115] The embodiments of the present disclosure provide another method for determining the HARQ codebook. Figure 9 It is a schematic flowchart of another method for determining the HARQ codebook provided by the embodiments of the present disclosure. This method for determining the HARQ codebook can be applied to a terminal device. This method for determining the HARQ codebook can be executed independently, or can be executed in combination with any one of the embodiments or possible implementation manners in the present disclosure, or can also be executed in combination with any one of the technical solutions in the related art.

[0116] As Figure 9 shown, this method for determining the HARQ codebook may include the following steps:

[0117] Step 901, in response to the HARQ enabling types of multiple PDSCH transmissions targeted on the specified HARQ feedback resource being all HARQ disabled, determine the HARQ feedback information corresponding to the multiple PDSCH transmissions in the HARQ codebook corresponding to the HARQ feedback resource according to the results of the multiple PDSCH transmissions.

[0118] It should be noted that the explanations of the HARQ feedback resources in the foregoing embodiments also apply to this embodiment and will not be elaborated here.

[0119] In an embodiment of the present disclosure, when the HARQ enabling types of multiple PDSCH transmissions targeted for transmission on a specified HARQ feedback resource are all disabled HARQ, the terminal device may determine, according to the results of the multiple PDSCH transmissions, the HARQ feedback information corresponding to the multiple PDSCH transmissions in the HARQ codebook corresponding to the HARQ feedback resource.

[0120] For example, referring to Figure 10 , taking the UL slot 7 as the specified HARQ feedback resource for illustrative purposes, assuming that the enabling types of the PDSCH transmissions scheduled in DL slots 0, 1, 2, and 3 are all disabled HARQ, and assuming that the terminal device correctly receives the PDSCH transmissions scheduled in DL slots 0 and 1, and fails to receive the PDSCH transmissions scheduled in DL slots 2 and 3, then the terminal device may determine that in the HARQ codebook corresponding to the HARQ feedback resource, the HARQ feedback information corresponding to the PDSCH transmissions scheduled in DL slots 0 and 1 is an acknowledgment message (i.e., the HARQ feedback information corresponding to the PDSCH transmissions scheduled in DL slots 0 and 1 is ACK and ACK respectively), and the HARQ feedback information corresponding to the PDSCH transmissions scheduled in DL slots 2 and 3 is a negative acknowledgment message (i.e., the HARQ feedback information corresponding to the PDSCH transmissions scheduled in DL slots 2 and 3 is NACK and NACK respectively).

[0121] The method for determining the HARQ codebook in the embodiment of the present disclosure enables the terminal device to determine the HARQ codebook corresponding to the HARQ feedback resource according to the HARQ enabling types of multiple PDSCH transmissions targeted for transmission on the specified HARQ feedback resource. Thus, the terminal device determines the HARQ codebook corresponding to the HARQ feedback resource in combination with the HARQ enabling types of multiple PDSCH transmissions, which can be applied to the scenario where HARQ is disabled and standardizes the HARQ feedback behavior of the terminal device.

[0122] It should be noted that these possible implementation manners described above may be executed independently or in combination, and the embodiments of the present disclosure do not make any limitations thereto.

[0123] The embodiment of the present disclosure provides another method for determining the HARQ codebook. Figure 11Schematic flow chart of another method for determining a HARQ codebook provided by an embodiment of the present disclosure. This method for determining a HARQ codebook can be applied to a terminal device. This method for determining a HARQ codebook can be executed alone, or can be executed in combination with any one embodiment in the present disclosure or a possible implementation manner in the embodiment, or can be executed in combination with any one technical solution in the related art.

[0124] As Figure 11 shown, this method for determining a HARQ codebook may include the following steps:

[0125] Step 1101, in response to the HARQ enabling type of some of the multiple PDSCH transmissions targeted on a specified HARQ feedback resource being HARQ enabled, determine that the HARQ codebook corresponding to the HARQ feedback resource only includes HARQ feedback information corresponding to some of the PDSCH transmissions.

[0126] It should be noted that the explanations of the HARQ feedback resource in the foregoing embodiments also apply to this embodiment and will not be elaborated here.

[0127] In an embodiment of the present disclosure, when the HARQ enabling type of some of the multiple PDSCH transmissions targeted on a specified HARQ feedback resource is HARQ enabled, the terminal device may determine that the HARQ codebook corresponding to the HARQ feedback resource only includes HARQ feedback information corresponding to this part of the PDSCH transmissions.

[0128] For example, referring to Figure 12 , taking the specified HARQ feedback resource as UL slot7 for illustrative purposes, assume that the enabling types of the PDSCH transmissions scheduled in DL slot 0 and 2 are HARQ enabled, and the enabling types of the PDSCH transmissions scheduled in DL slot 1 and 3 are not HARQ enabled. Also, assume that for the PDSCH transmissions scheduled in DL slot 0 and 1, the terminal device correctly receives them, and for the PDSCH transmissions scheduled in DL slot 2 and 3, the terminal device fails to receive them. Then the terminal device may determine that the HARQ codebook corresponding to the HARQ feedback resource only includes the HARQ feedback information (ACK) corresponding to the PDSCH transmission scheduled in DL slot 0, and the HARQ feedback information (NACK) corresponding to the PDSCH transmission scheduled in DL slot 2.

[0129] The method for determining a HARQ codebook according to an embodiment of the present disclosure enables a terminal device to determine a HARQ codebook corresponding to a HARQ feedback resource based on the HARQ enabling types for multiple PDSCH transmissions targeted on a specified HARQ feedback resource. Thus, by combining the HARQ enabling types for multiple PDSCH transmissions, the terminal device determines the HARQ codebook corresponding to the HARQ feedback resource, which can be applicable to scenarios where HARQ is not enabled and standardizes the HARQ feedback behavior of the terminal device.

[0130] It should be noted that these possible implementation manners described above can be executed independently or in combination, and the embodiments of the present disclosure do not make any limitations thereto.

[0131] The embodiment of the present disclosure provides another method for determining a HARQ codebook. Figure 13 It is a schematic flowchart of another method for determining a HARQ codebook provided by an embodiment of the present disclosure. This method for determining a HARQ codebook can be applied to a terminal device. This method for determining a HARQ codebook can be executed independently, or can be executed in combination with any one embodiment or possible implementation manner in the present disclosure, or can also be executed in combination with any technical solution in related technologies.

[0132] As Figure 13 shown, this method for determining a HARQ codebook may include the following steps:

[0133] Step 1301: In response to the HARQ enabling type for some of the multiple PDSCH transmissions targeted on a specified HARQ feedback resource being HARQ enabled, determine that the HARQ codebook corresponding to the HARQ feedback resource is empty.

[0134] It should be noted that the explanation of the HARQ feedback resource in the foregoing embodiment also applies to this embodiment and will not be elaborated herein.

[0135] In an embodiment of the present disclosure, when the HARQ enabling type for some of the multiple PDSCH transmissions targeted on a specified HARQ feedback resource is HARQ enabled, the terminal device can determine that the HARQ codebook corresponding to the HARQ feedback resource is empty, that is, the terminal device does not need to feedback HARQ feedback information to the network device.

[0136] In a possible implementation manner of the embodiments of the present disclosure, after the terminal device determines that the HARQ codebook corresponding to the HARQ feedback resource is empty, the network device will not be able to receive the HARQ feedback information of the terminal device on the HARQ feedback resource. Then, the network device may send a HARQ feedback indication to the terminal device to instruct the terminal device to feedback the feedback information including the HARQ feedback information corresponding to this part of the PDSCH transmission. Correspondingly, after receiving the HARQ feedback indication from the network device, the terminal device may send the HARQ feedback information corresponding to this part of the PDSCH transmission to the network device.

[0137] For example, as Figure 12 shown, taking the specified HARQ feedback resource as UL slot7 for illustrative purposes, assume that the enabling types of the PDSCH transmissions scheduled by DL slot 0 and 2 are enabling HARQ, and the enabling types of the PDSCH transmissions scheduled by DL slot 1 and 3 are disabling HARQ. Also, assume that for the PDSCH transmissions scheduled on DL slot 0 and 1, the terminal device correctly receives them, and for the PDSCH transmissions scheduled on DL slot 2 and 3, the terminal device fails to receive them. The terminal device may not need to feedback the HARQ feedback information. After the network device fails to receive the HARQ feedback information of the terminal device on the HARQ feedback resource, it may send a HARQ feedback indication to the terminal device. Correspondingly, after receiving the HARQ feedback indication from the network device, the terminal device may send the HARQ feedback information (ACK) corresponding to the PDSCH transmission scheduled on DL slot 0, and the HARQ feedback information (NACK) corresponding to the PDSCH transmission scheduled on DL slot 2, to the network device.

[0138] The method for determining the HARQ codebook in the embodiments of the present disclosure determines the HARQ codebook corresponding to the HARQ feedback resource by the terminal device according to the HARQ enabling types of multiple PDSCH transmissions targeted on the specified HARQ feedback resource. Thus, the terminal device combines the HARQ enabling types of multiple PDSCH transmissions to determine the HARQ codebook corresponding to the HARQ feedback resource, which can be applicable to the scenario where HARQ is disabled and standardizes the HARQ feedback behavior of the terminal device.

[0139] It should be noted that these possible implementation manners described above may be executed independently or in combination, and the embodiments of the present disclosure do not make any limitations in this regard.

[0140] The embodiments of the present disclosure provide another method for determining the HARQ codebook. Figure 14Schematic flowchart of another method for determining a HARQ codebook provided by an embodiment of the present disclosure. This method for determining a HARQ codebook can be applied to a terminal device. This method for determining a HARQ codebook can be executed alone, or can be executed in combination with any one of the embodiments in the present disclosure or possible implementation manners in the embodiments, or can also be executed in combination with any one of the technical solutions in the related art.

[0141] As Figure 14 shown, this method for determining a HARQ codebook may include the following steps:

[0142] Step 1401: Determine the HARQ codebook corresponding to the HARQ feedback resource according to the HARQ enabling types of multiple PDSCH transmissions targeted on the specified HARQ feedback resource.

[0143] In the embodiments of the present disclosure, step 1401 can be implemented in any one of the embodiments of the present disclosure. The embodiments of the present disclosure do not make any limitations on this and will not elaborate further.

[0144] Step 1402: Feed back HARQ feedback information corresponding to multiple PDSCH transmissions to the network device on the HARQ feedback resource according to the HARQ codebook.

[0145] In the embodiments of the present disclosure, after determining the HARQ codebook corresponding to the HARQ feedback resource, the terminal device can feed back HARQ feedback information corresponding to multiple PDSCH transmissions to the network device on the HARQ feedback resource according to the above HARQ codebook.

[0146] In a possible implementation manner of the embodiments of the present disclosure, when the HARQ codebook is empty, the terminal device can give up feeding back HARQ feedback information corresponding to multiple PDSCH transmissions to the network device on the HARQ feedback resource.

[0147] In another possible implementation manner of the embodiments of the present disclosure, when the HARQ codebook is non-empty, the terminal device can feed back the HARQ feedback information in the HARQ codebook to the network device on the HARQ feedback resource.

[0148] As an example, as Figure 12 shown, the terminal device can feed back ACK and NACK to the network device on the HARQ feedback resource; as Figure 10 shown, the terminal device can feed back ACK, ACK, NACK, and NACK to the network device on the HARQ feedback resource.

[0149] The method for determining a HARQ codebook according to an embodiment of the present disclosure enables a terminal device to determine a HARQ codebook corresponding to a HARQ feedback resource based on the HARQ enabling types for multiple PDSCH transmissions on a specified HARQ feedback resource. Thus, by combining the HARQ enabling types for multiple PDSCH transmissions, the terminal device determines the HARQ codebook corresponding to the HARQ feedback resource, which can be applicable to scenarios where HARQ is not enabled and standardizes the HARQ feedback behavior of the terminal device.

[0150] It should be noted that these possible implementation manners described above can be executed independently or in combination, and the embodiments of the present disclosure do not make any limitations in this regard.

[0151] An embodiment of the present disclosure provides a method for receiving HARQ feedback information. Figure 15 The flowchart of a method for receiving HARQ feedback information provided by an embodiment of the present disclosure is shown. This method for receiving HARQ feedback information can be applied to a network device. This method for receiving HARQ feedback information can be executed independently, or can be executed in combination with any one of the embodiments or possible implementation manners in the present disclosure, or can also be executed in combination with any one of the technical solutions in the related art.

[0152] As Figure 15 shown, the method for receiving HARQ feedback information may include the following steps:

[0153] Step 1501: Determine the receiving manner of the HARQ feedback information according to the HARQ enabling types for multiple PDSCH transmissions on a specified HARQ feedback resource.

[0154] It should be noted that the explanations of the HARQ feedback resource and the HARQ enabling type in the foregoing embodiments also apply to this embodiment, and will not be elaborated herein.

[0155] In an embodiment of the present disclosure, a network device can determine the receiving manner of the HARQ feedback information according to the HARQ enabling types for multiple PDSCH transmissions on a specified HARQ feedback resource, that is, determine whether to receive the HARQ feedback information of the terminal device on the HARQ feedback resource. Thus, by combining the HARQ enabling types for multiple PDSCH transmissions, the network device determines the receiving manner of the HARQ feedback information, which can ensure the reliability of data transmission.

[0156] The method for receiving HARQ feedback information according to an embodiment of the present disclosure enables a network device to determine the receiving manner of HARQ feedback information based on the HARQ enabling types for multiple PDSCH transmissions carried on a specified HARQ feedback resource. Thus, by combining the HARQ enabling types for multiple PDSCH transmissions, the network device determines the receiving manner of HARQ feedback information, which can ensure the reliability of data transmission.

[0157] Another method for receiving HARQ feedback information is provided in an embodiment of the present disclosure. Figure 16 It is a schematic flowchart of another method for receiving HARQ feedback information provided in an embodiment of the present disclosure. This method for receiving HARQ feedback information can be applied to a network device. This method for receiving HARQ feedback information can be executed alone, or can be executed in combination with any one of the embodiments in the present disclosure or possible implementation manners in the embodiments, or can also be executed in combination with any one of the technical solutions in the related art.

[0158] As Figure 16 shown, the method for receiving HARQ feedback information may include the following steps:

[0159] Step 1601: In response to the HARQ enabling types for multiple PDSCH transmissions carried on a specified HARQ feedback resource all being enabled HARQ, determine to receive the HARQ feedback information of the terminal device on the HARQ feedback resource.

[0160] It should be noted that the explanations of the HARQ feedback resource in the foregoing embodiments also apply to this embodiment and will not be elaborated herein.

[0161] In an embodiment of the present disclosure, when the HARQ enabling types for multiple PDSCH transmissions carried on a specified HARQ feedback resource are all enabled HARQ, the terminal device can determine the HARQ feedback information corresponding to multiple PDSCH transmissions in the HARQ codebook corresponding to the HARQ feedback resource according to the results of multiple PDSCH transmissions. After the terminal device determines the HARQ feedback information corresponding to multiple PDSCH transmissions, it can send the HARQ feedback information corresponding to multiple PDSCH transmissions to the network device on the specified HARQ feedback resource. In this way, in order to ensure the reliability of data transmission, the network device can determine to receive the HARQ feedback information of the terminal device on the HARQ feedback resource.

[0162] As an example, referring to Figure 4 , the HARQ feedback information sent by the terminal device to the network device on the specified HARQ feedback resource may be: ACK, ACK, NACK, NACK.

[0163] The method for receiving HARQ feedback information according to an embodiment of the present disclosure enables a network device to determine the receiving manner of HARQ feedback information based on the HARQ enabling types for multiple PDSCH transmissions carried on a specified HARQ feedback resource. Thus, by combining the HARQ enabling types for multiple PDSCH transmissions, the network device determines the receiving manner of HARQ feedback information, which can ensure the reliability of data transmission.

[0164] It should be noted that these possible implementation manners described above can be executed independently or in combination, and the embodiments of the present disclosure do not limit this.

[0165] The embodiments of the present disclosure provide another method for receiving HARQ feedback information. Figure 17 It is a schematic flowchart of another method for receiving HARQ feedback information provided by an embodiment of the present disclosure. This method for receiving HARQ feedback information can be applied to a network device. This method for receiving HARQ feedback information can be executed independently, or in combination with any one of the embodiments or possible implementation manners in the present disclosure, or in combination with any one of the technical solutions in related technologies.

[0166] As Figure 17 shown, this method for receiving HARQ feedback information may include the following steps:

[0167] Step 1701, in response to the HARQ enabling types for multiple PDSCH transmissions carried on a specified HARQ feedback resource all being non-enabled HARQ, determine not to receive the HARQ feedback information of the terminal device on the HARQ feedback resource.

[0168] It should be noted that the explanation of the HARQ feedback resource in the foregoing embodiment also applies to this embodiment and will not be repeated here.

[0169] In a possible implementation manner of the embodiments of the present disclosure, when the HARQ enabling types for multiple PDSCH transmissions carried on a specified HARQ feedback resource are all disabled HARQ, the terminal device may determine that the HARQ codebook corresponding to the HARQ feedback resource is empty, that is, the terminal device may abandon the HARQ feedback for the above multiple PDSCH transmissions. In this way, in order to reduce the power consumption and processing burden of the network device, the network device may not need to receive the HARQ feedback information of the terminal device, that is, the network device may determine not to receive the HARQ feedback information of the terminal device on the HARQ feedback resource.

[0170] In another possible implementation manner of the embodiments of the present disclosure, when the HARQ enabling types of multiple PDSCH transmissions targeted for transmission on a specified HARQ feedback resource are all disabled HARQ, the terminal device may determine that the HARQ feedback information corresponding to the multiple PDSCH transmissions in the HARQ codebook corresponding to the HARQ feedback resource is negative acknowledgment information (NACK). In this way, in order to reduce the power consumption and processing burden of the network device, the network device may not need to receive the HARQ feedback information of the terminal device, that is, the network device may determine not to receive the HARQ feedback information of the terminal device on the HARQ feedback resource.

[0171] In yet another possible implementation manner of the embodiments of the present disclosure, when the HARQ enabling types of multiple PDSCH transmissions targeted for transmission on a specified HARQ feedback resource are all disabled HARQ, the terminal device may determine the HARQ feedback information corresponding to the multiple PDSCH transmissions in the HARQ codebook corresponding to the HARQ feedback resource according to the results of the multiple PDSCH transmissions. In this way, in order to reduce the power consumption and processing burden of the network device, the network device may not need to receive the HARQ feedback information of the terminal device, that is, the network device may determine not to receive the HARQ feedback information of the terminal device on the HARQ feedback resource.

[0172] The method for receiving HARQ feedback information in the embodiments of the present disclosure determines the receiving manner of the HARQ feedback information by the network device according to the HARQ enabling types of multiple PDSCH transmissions targeted for transmission on a specified HARQ feedback resource. Thus, the network device combines the HARQ enabling types of multiple PDSCH transmissions to determine the receiving manner of the HARQ feedback information, which can ensure the reliability of data transmission.

[0173] It should be noted that the above possible implementation manners may be executed separately or in combination, and the embodiments of the present disclosure do not make any limitations in this regard.

[0174] The embodiments of the present disclosure provide another method for receiving HARQ feedback information. Figure 18 It is a schematic flowchart of another method for receiving HARQ feedback information provided by the embodiments of the present disclosure. This method for receiving HARQ feedback information may be applied to a network device. This method for receiving HARQ feedback information may be executed separately, or may be executed in combination with any one of the embodiments or possible implementation manners in the present disclosure, or may be executed in combination with any one of the technical solutions in the related art.

[0175] As Figure 18 shown, this method for receiving HARQ feedback information may include the following steps:

[0176] Step 1801: In response to the HARQ enabling types of multiple targeted PDSCH transmissions on the specified HARQ feedback resource all being non-enabled HARQ, determine to receive the HARQ feedback information of the terminal device on the HARQ feedback resource, and discard the received HARQ feedback information.

[0177] It should be noted that the explanations of the HARQ feedback resource in the foregoing embodiments also apply to this embodiment and will not be elaborated herein.

[0178] In a possible implementation manner of the embodiments of the present disclosure, when the HARQ enabling types of multiple targeted PDSCH transmissions on the specified HARQ feedback resource are all non-enabled (disabled) HARQ, the terminal device may determine that the HARQ feedback information corresponding to the multiple PDSCH transmissions in the HARQ codebook corresponding to the HARQ feedback resource is negative acknowledgment information (NACK). In this way, the network device may receive the HARQ feedback information of the terminal device on the HARQ feedback resource, but discard the received HARQ feedback information.

[0179] In another possible implementation manner of the embodiments of the present disclosure, when the HARQ enabling types of multiple targeted PDSCH transmissions on the specified HARQ feedback resource are all non-enabled (disabled) HARQ, the terminal device may determine the HARQ feedback information corresponding to the multiple PDSCH transmissions in the HARQ codebook corresponding to the HARQ feedback resource according to the results of the multiple PDSCH transmissions. In this way, the network device may receive the HARQ feedback information of the terminal device on the HARQ feedback resource, but discard the received HARQ feedback information.

[0180] The method for receiving HARQ feedback information in the embodiments of the present disclosure determines the receiving manner of the HARQ feedback information by the network device according to the HARQ enabling types of multiple targeted PDSCH transmissions on the specified HARQ feedback resource. Thus, the network device combines the HARQ enabling types of multiple PDSCH transmissions to determine the receiving manner of the HARQ feedback information, which can ensure the reliability of data transmission.

[0181] It should be noted that these possible implementation manners described above may be executed independently or in combination, and the embodiments of the present disclosure do not limit this.

[0182] The embodiments of the present disclosure provide another method for receiving HARQ feedback information. Figure 19Schematic flowchart of another method for receiving HARQ feedback information provided by an embodiment of the present disclosure. The method for receiving HARQ feedback information can be applied to a network device. The method for receiving HARQ feedback information can be executed alone, or can be executed in combination with any one of the embodiments in the present disclosure or possible implementation manners in the embodiments, or can be executed in combination with any one of the technical solutions in the related art.

[0183] As Figure 19 shown, the method for receiving HARQ feedback information may include the following steps:

[0184] Step 1901, in response to the HARQ enabling type of some of the multiple PDSCH transmissions targeted on the specified HARQ feedback resource being HARQ enabled, determine to receive the HARQ feedback information of the terminal device on the HARQ feedback resource.

[0185] It should be noted that the explanation of the HARQ feedback resource in the foregoing embodiment also applies to this embodiment and will not be elaborated here.

[0186] In an embodiment of the present disclosure, when the HARQ enabling type of some of the multiple PDSCH transmissions targeted on the specified HARQ feedback resource is HARQ enabled, the terminal device may determine that the HARQ codebook corresponding to the HARQ feedback resource only includes the HARQ feedback information corresponding to this part of the PDSCH transmissions. In this way, in order to enable the network device to timely learn about the data reception situation of the terminal device, the network device may receive the HARQ feedback information of the terminal device on the HARQ feedback resource, that is, the network device may determine to receive the HARQ feedback information of the terminal device on the HARQ feedback resource.

[0187] In a possible implementation manner of the embodiment of the present disclosure, when the HARQ enabling type of some of the multiple PDSCH transmissions targeted on the specified HARQ feedback resource is HARQ enabled, the terminal device may determine that the HARQ codebook corresponding to the HARQ feedback resource is empty, that is, the terminal device does not need to feedback HARQ feedback information.

[0188] After the network device fails to receive the HARQ feedback information of the terminal device on the HARQ feedback resource, it may send a HARQ feedback indication to the terminal device to indicate that the terminal device feedbacks the feedback information including the HARQ feedback information corresponding to this part of the PDSCH transmissions. Correspondingly, after receiving the HARQ feedback indication from the network device, the terminal device may send the HARQ feedback information corresponding to some of the PDSCH transmissions to the network device.

[0189] The method for receiving HARQ feedback information according to the embodiments of the present disclosure enables a network device to determine the receiving manner of HARQ feedback information based on the HARQ enabling types for multiple PDSCH transmissions on a specified HARQ feedback resource. Thus, by combining the HARQ enabling types for multiple PDSCH transmissions, the network device determines the receiving manner of HARQ feedback information, which can ensure the reliability of data transmission.

[0190] It should be noted that these possible implementation manners above can be executed independently or in combination, and the embodiments of the present disclosure do not make any limitations thereto.

[0191] In an embodiment of the present disclosure, a terminal device can determine a semi-static HARQ codebook through the following method:

[0192] First, when all HARQ processes included in the HARQ codebook at the moment to be fed back are HARQ enabled processes, the terminal device can report HARQ feedback information according to the Rel-15 design. That is to say, the size of the HARQ codebook determined by the terminal device is predefined or preconfigured, and at the same time, the terminal device can determine the HARQ feedback information based on the result of data demodulation.

[0193] Second, when all HARQ processes included in the HARQ codebook at the moment to be fed back are HARQ disabled processes,

[0194] Method 1: The terminal device abandons the feedback of this HARQ

[0195] When the terminal device determines that all HARQ feedback information to be fed back on this HARQ feedback resource is for PDSCH transmissions with HARQ disabled, the terminal device can abandon the transmission of this HARQ feedback resource.

[0196] The network device does not need to receive the HARQ feedback information of the terminal device.

[0197] When the network device determines that all HARQ feedback information scheduled or configured on a certain HARQ feedback resource is for PDSCH transmissions with HARQ disabled, the network device will not receive the HARQ feedback information of the terminal device on this HARQ feedback resource.

[0198] Method 2: The terminal device feeds back pre-set HARQ feedback information

[0199] The terminal device feeds back pre-set HARQ feedback information. For example, the terminal device can feed back NACK regardless of the decoding result of the PDSCH transmission. Figure 8As shown in the figure, it is assumed that the terminal devices that receive the PDSCH transmissions scheduled on DL slots 0 and 1 receive them correctly, and the terminal devices that receive the PDSCH transmissions scheduled on DL slots 2 and 3 receive them incorrectly. However, since the enabling types of these four PDSCH transmissions are all HARQ disabled, the terminal device can ignore the data reception situation, and the HARQ feedback information for these 4 PDSCH transmissions is all NACK.

[0200] The network device does not need to receive the HARQ feedback information from the terminal device, that is, the network device can not receive the HARQ feedback message on the HARQ feedback resource. Or, in another implementation method, the network device can receive the HARQ feedback message on the HARQ feedback resource, but the network device ignores the indication content carried in the HARQ feedback information.

[0201] Method 3: The terminal device feeds back correct HARQ feedback information based on the decoding result

[0202] The terminal device determines the HARQ feedback information to be fed back based on the data reception situation. As Figure 10 shown in the figure, it is assumed that the terminal devices that receive the PDSCH transmissions scheduled on DL slots 0 and 1 receive them correctly, and the terminal devices that receive the PDSCH transmissions scheduled on DL slots 2 and 3 receive them incorrectly. Therefore, the terminal device can determine that the HARQ feedback information for these 4 PDSCH transmissions is ACK, ACK, NACK, and NACK respectively.

[0203] The network device does not need to receive the HARQ feedback information from the terminal device, that is, the network device can not receive the HARQ feedback message on the HARQ feedback resource. Or, in another implementation method, the network device can receive the HARQ feedback message on the HARQ feedback resource, but the network device ignores the indication content carried in the HARQ feedback information.

[0204] Thirdly, when some of the HARQ processes included in the HARQ codebook at the moment to be fed back are HARQ enabled processes and some are HARQ disabled processes,

[0205] Method 1: The terminal device can determine the HARQ codebook size based on the number of HARQ enabled HARQ processes in the HARQ process to be fed back, generate the HARQ codebook in a predefined order, and feed back the HARQ feedback information based on the decoding result. As Figure 12As shown, for a certain terminal device, it is assumed that the PDSCH transmissions scheduled on DL slots 0 and 2 are HARQ-enabled, and the PDSCH transmissions scheduled on DL slots 1 and 3 are HARQ-disabled. It is also assumed that the terminal device correctly receives the PDSCH transmissions scheduled on DL slots 0 and 1, and fails to receive the PDSCH transmissions scheduled on DL slots 2 and 3. Therefore, the HARQ codebook fed back by the terminal device carries HARQ feedback information for the two PDSCH transmissions, namely the HARQ feedback information corresponding to the PDSCH transmissions scheduled on DL slots 0 and 2. Based on the receiving results of the terminal device, it can be determined that the HARQ feedback information corresponding to the PDSCH transmissions scheduled on DL slots 0 and 2 is ACK and NACK respectively.

[0206] The network device receives the HARQ feedback information of the terminal device.

[0207] The network device can receive the HARQ feedback information on the pre-defined or indicated HARQ feedback resources to learn about the data reception situation of the terminal device.

[0208] Method 2: The terminal device considers it an error case and does not feedback any HARQ feedback information. The terminal device transmits the HARQ feedback information that needs to be fed back based on the subsequent indication of the network device.

[0209] The network device triggers the retransmission of the HARQ feedback information of the un-fed-back HARQ-enabled process.

[0210] Thus, a design method for the HARQ semi-static codebook is proposed, which can standardize the HARQ feedback behavior of the terminal device and ensure the reliability of data transmission.
