Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a method and apparatus for HARQ feedback of CG resources. Background Art

[0002] Generally, due to the long round-trip time (RTT) in the non-terrestrial network (NTN), in order to ensure the time of retransmission scheduling, when the semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH) needs to be feedback-enabled, it is necessary to configure multiple hybrid automatic repeat request (HARQ) process identifiers (Identity documents, IDs) for the SPS PDSCH.

[0003] In order to ensure the time of retransmission scheduling, more HARQ process IDs need to be configured. However, the SPS PDSCH period, RTT period, and maximum number of retransmissions affect the number of HARQ process IDs. This may cause a contradiction between the SPS PDSCH period and the HARQ process ID configuration in the NTN network. Summary of the Invention

[0072] To facilitate understanding, the terms involved in this application are first introduced.

[0073] 1. Hybrid Automatic Repeat request (HARQ)

[0074] HARQ is a technology that combines forward error correction (FEC) and automatic repeat-request (ARQ).

[0075] 2. Downlink Control Information (DCI)

[0076] DCI is control information related to the Physical Uplink and Downlink Shared Channels (PUSCH and PDSCH) transmitted on the Physical Downlink Control Channel (PDCCH). This DCI includes information such as resource block (RB) allocation and modulation scheme. Only when the terminal correctly decodes the DCI information can it correctly process PDSCH or PUSCH data.

[0077] 3. Configured grant (CG) resources

[0078] CG resources do not require DCI dynamic scheduling and are pre-configured by Radio Resource Control (RRC), sometimes also called semi-static scheduling. In contrast, dynamic scheduling (DG) resources require DCI dynamic scheduling.

[0079] In order to better understand the method for determining the side link duration disclosed in an embodiment of the present application, the communication system to which the embodiment of the present application is applicable is first described below.

[0080] See Figure 1 , Figure 1 This is a schematic diagram of the architecture of a communication system provided in an embodiment of the present application. The communication system may include but is not limited to a network device and a terminal device. Figure 1 The number and form of the devices shown are for example only and do not constitute a limitation on the embodiments of the present application. In actual applications, two or more network devices and two or more terminal devices may be included. Figure 1 The communication system shown includes a network device 101 and a terminal device 102 as an example.

It should also be noted that the side link in the embodiments of the present application can also be referred to as a side link or a direct link.

[0082] The network device 101 in the embodiment of the present application is an entity on the network side for transmitting or receiving signals. For example, the network device 101 can be an evolved NodeB (eNB), a transmission point (TRP), a next generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. The embodiments of the present application do not limit the specific technology and specific device form adopted by the network device. The network device provided in the embodiment of the present application can be composed of a centralized unit (CU) and a distributed unit (DU), wherein the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the network device, such as the base station, and the functions of some protocol layers are placed in the CU for centralized control, and the functions of the remaining part or all of the protocol layers are distributed in the DU, and the DU is centrally controlled by the CU.

[0083] The terminal device 102 in the embodiment of the present application is an entity on the user side for receiving or transmitting signals, such as a mobile phone.

[0084] It can be understood that the communication system described in the embodiment of the present application is for the purpose of more clearly illustrating the technical solution of the embodiment of the present application, and does not constitute a limitation on the technical solution provided by the embodiment of the present application. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present application is also applicable to similar technical problems.

[0085] The following is a detailed introduction to the HARQ feedback method and device for CG resources provided in this application in conjunction with the accompanying drawings.

[0086] See Figure 2 , Figure 2 This is a flow chart of a HARQ feedback method for CG resources provided in an embodiment of the present application, which is executed by a terminal device. Figure 2 As shown, the method may include but is not limited to the following steps:

[0087] Step S201, determine the HARQ feedback cycle corresponding to the CG resource.

[0088] CG resources do not require DCI dynamic scheduling and are RRC pre-configured resources, sometimes also called semi-static scheduling. CG resources can be uplink CG resources or downlink CG resources.

[0089] Downlink CG resources are generally referred to as SPS PDSCH. For downlink SPS PDSCH, after RRC configuration is completed, it is necessary to receive an activation signal sent by the network device for the SPS PDSCH setting, namely sps activation. The activation signal is a special scrambled DCI. The terminal device can receive SPS PDSCH in a specific time unit according to the instructions of the activation signal. There are two types of uplink CG resources, namely Type-1 CG and Type-2 CG. Both Type-1 CG and Type-2 CG require RRC configuration. Among them, Type-1 CG has the same transmission method as SPS PDSCH and requires DCI activation to transmit information, while Type-2CG can transmit information without activation.

[0090] In communication systems, due to the impact of time-varying characteristics of wireless channels and multipath fading on signal transmission, as well as some unpredictable interference that may cause signal transmission failure, HARQ is usually used for error control to ensure transmission quality.

[0091] In some implementations, the HARQ feedback period corresponding to the CG resource can be confirmed according to the protocol agreement. In some implementations, the HARQ feedback period corresponding to the CG resource can be confirmed according to the configuration information sent by the network device. In the present application, the HARQ feedback period can be the time interval between two consecutive times that the HARQ process corresponding to the same HARQ process ID in the feedback-enabled state is used by the CG resource. It should be noted that, in order to determine the HARQ process ID, the HARQ feedback period parameter is newly introduced in the present application, and the HARQ process ID is determined based on the HARQ feedback period parameter.

[0092] Step S202: Determine whether to perform HARQ feedback on the information transmitted on the CG resource according to the HARQ feedback cycle.

[0093] In some implementations, after obtaining the HARQ feedback period, the HARQ process ID corresponding to the CG resource can be determined based on the HARQ feedback period. Further, based on the HARQ process ID corresponding to the CG resource, it is determined whether to perform HARQ feedback on the information transmitted on the CG resource.

[0094] Optionally, in response to the HARQ process ID corresponding to the CG resource being in a feedback-enabled state, it is determined that HARQ feedback is required for the information transmitted on the CG resource.

[0095] Optionally, in response to the HARQ process ID corresponding to the CG resource being in a feedback disabled state, it is determined that no HARQ feedback is required for the information transmitted on the CG resource.

[0096] In an embodiment of the present application, a hybrid automatic repeat request (HARQ) feedback period corresponding to the configured authorized CG resource is determined, and based on the HARQ feedback period, it is determined whether HARQ feedback is performed on the information transmitted on the CG resource. Thus, by introducing the HARQ feedback period to determine the HARQ process ID, the determination of the HARQ process ID is decoupled from the SPS PDSCH period, and the conflict between the SPS PDSCH period and the HARQ process ID can be reconciled, thereby improving the speed and quality of data transmission, increasing the flexibility of data transmission, and avoiding data transmission errors.

[0097] See Figure 3 , Figure 3 This is a flow chart of a HARQ feedback method for CG resources provided in an embodiment of the present application, which is executed by a terminal device. Figure 3 As shown, the method may include but is not limited to the following steps:

[0098] Step S301, determine the HARQ feedback cycle corresponding to the CG resource.

[0099] Regarding the implementation of step S301, please refer to any implementation in the embodiments of this application, and will not be repeated here.

[0100] Step S302: In response to the HARQ process identifier being configured for the CG resource of the terminal device, the HARQ process identifier corresponding to the CG resource in different time units is determined according to the HARQ feedback cycle.

[0101] In some implementations, a network device or protocol agreement configures a HARQ process ID for the CG resources of a terminal device. Typically, the HARQ process ID corresponding to the CG resources is configured through RRC signaling. Optionally, the network device configures the HARQ process ID for the CG resources of the terminal device. The terminal device can receive RRC configuration information sent by the network device and determine the HARQ process ID corresponding to the CG resources based on the configuration information. In some implementations, the configuration information includes feedback enabling information for the HARQ process ID and / or HARQ process ID configured for the terminal device.

[0102] In some implementations, the configuration information includes a HARQ process identifier configured for the terminal device, and feedback enablement information for the HARQ process identifier can be confirmed based on the HARQ process identifier. For example, the network device can determine the maximum number of HARQ process IDs that can be indicated in the DCI based on the capabilities of the terminal device. If the capability of the terminal device is 32, the maximum number of HARQ process IDs that can be indicated in the DCI is 32. In other words, the network device configures 32 HARQ process IDs through RRC, where feedback enablement information for HARQ process IDs #0 to #15 indicates that the HARQ process identifier is in a feedback disabled state, and feedback enablement information for HARQ process IDs #16 to #31 indicates that the HARQ process identifier is in a feedback enabled state.

[0103] In some implementations, the configuration information includes a HARQ process identifier configured for the terminal device and feedback enabling information of the HARQ process identifier. In some implementations, the configuration information includes feedback enabling information of the HARQ process identifier configured for the terminal device.

[0104] After obtaining the HARQ feedback cycle, the HARQ process ID corresponding to the CG resource can be determined based on the HARQ feedback cycle and a preset strategy.

[0105] It should be noted that the network device may not directly configure the HARQ process identifier of the CG resource to the terminal device, but may configure the number of HARQ processes that can be used by the CG resource, and the terminal device may determine the HARQ process identifier corresponding to the CG resource in different time units based on the time unit in which the CG resource is located and other RRC parameters. Since the HARQ process identifier of the CG resource can be calculated through RRC parameters, for simplicity, the following description is expressed in terms of the HARQ process identifier configured for the CG resource. However, it can be understood that configuring the HARQ process identifier for the CG resource does not exclude the situation where the HARQ process identifier of the CG resource is calculated by configuring the total number of HARQ processes for the CG resource.

[0106] Step S303: Based on the feedback enable information of the HARQ process identifier, determine whether to perform HARQ feedback on the information transmitted on the time unit corresponding to the CG resource.

[0107] The terminal device can receive information transmitted by the network device on the CG resource. In an embodiment of the present application, after receiving the information, the terminal device determines whether to perform HARQ feedback on the information transmitted on the time unit corresponding to the CG resource based on the HARQ process ID corresponding to the CG resource. In some implementations, if the feedback enable information of the HARQ process ID corresponding to the CG resource indicates that the HARQ process ID is in a feedback-enabled state, the terminal device can perform HARQ feedback on the information transmitted on the time unit corresponding to the CG resource on the HARQ process identified by the HARQ process ID. In other words, the network device can receive HARQ feedback from the terminal device for the information received from the CG resource. For example, if the determined HARQ process ID corresponding to the CG resource is #16 or #17, then all the information transmitted on the time unit corresponding to the CG resource needs to perform HARQ feedback.

[0108] In some implementations, if the feedback enable information of the HARQ process ID corresponding to the CG resource indicates that the HARQ process ID is in a feedback disabled state, the terminal device may not perform HARQ feedback on the information transmitted on the time unit corresponding to the CG resource on the HARQ process identified by the HARQ process ID. That is, the network device cannot receive HARQ feedback from the terminal device for the information received from the CG resource. For example, if the HARQ process ID corresponding to the determined CG resource is #0 or #1, then no HARQ feedback is required for the information transmitted on the time unit corresponding to the CG resource. For example, if the HARQ process ID corresponding to the determined CG resource is #15 or #16, then part of the information transmitted on the time unit corresponding to the CG resource requires HARQ feedback, and part does not require HARQ feedback. That is, if the HARQ process ID corresponding to the determined CG resource is #15, part of the information transmitted on the time unit corresponding to the CG resource does not require HARQ feedback, and if the HARQ process ID corresponding to the determined CG resource is #16, part of the information transmitted on the time unit corresponding to the CG resource requires HARQ feedback.

[0109] In an embodiment of the present application, the HARQ process ID corresponding to the CG resources on different time units is determined from the configured HARQ process ID according to the HARQ feedback cycle. Based on the feedback enable information of the HARQ process ID, it is determined whether to perform HARQ feedback on the information transmitted on the time unit corresponding to the CG resource. In an embodiment of the present application, the HARQ process ID is determined by introducing a HARQ feedback cycle, so that the determination of the HARQ process ID is untied from the SPS PDSCH cycle, and the contradiction between the SPS PDSCH cycle and the HARQ process ID can be coordinated, which can improve the speed and quality of data transmission, improve the flexibility of data transmission, and avoid data transmission errors.

[0110] See Figure 4 , Figure 4 This is a flow chart of a HARQ feedback method for CG resources provided in an embodiment of the present application, which is executed by a terminal device. Figure 4 As shown, the method may include but is not limited to the following steps:

[0111] Step S401, determine the HARQ feedback cycle corresponding to the CG resource.

[0112] Regarding the implementation of step S401, please refer to any implementation in the embodiments of this application, and will not be repeated here.

[0113] Step S402, determine the time unit where the currently received CG resource is located.

[0114] In some implementations, the CG resource is a downlink CG resource, namely, SPS PDSCH, and the time unit is the time slot where the currently received CG resource is located.

[0115] In some implementations, the CG resource is an uplink CG resource, namely Type-1 CG and Type-2 CG, and the time unit is the symbol where the currently received CG resource is located.

[0116] Step S403: Determine the value of the selection factor based on the time unit and the HARQ feedback cycle.

[0117] In response to the CG resource being a downlink CG resource, a first parameter is determined based on a time unit, a second parameter is determined based on the number of consecutive time slots per frame and the HARQ feedback cycle, and the remainder between the first parameter and the second parameter is obtained as the value of the selection factor. For example, the product of the time slot number of the CG resource currently received by the terminal device and the preset threshold is used as the first parameter, and the product of the number of consecutive time slots per frame and the HARQ feedback cycle is used as the second parameter, then the selection factor is:

[0118] X=modulo(CURRENT slot ×N / (periodicity ID×SPF)) (1)

[0119] Among them, X is the selected factor, modulo(......) is the remainder operation, CURRENT slot is the number of the time slot where the CG resource received by the terminal device is located, N is the preset threshold, and periodicity ID is the HARQ feedback period. Optionally, in this embodiment of the present application, N can be 10. In this embodiment of the present application, CURRENT slot =(SFN×SPF)+slot number in the frame, where SPF is the number of consecutive time slots in each frame, SFN is the system frame number, and slot number in the frame is the time slot number where the SPS PDSCH is currently received.

[0120] In response to the CG resource being an uplink CG resource, the remainder between the time unit and the feedback cycle is obtained as the value of the selection factor. The selection factor is:

[0121] X=modulo(CURRENT symbol / periodicity ID) (2)

[0122] Among them, CURRENT symbolIt is the number of the symbol where the CG resource currently received by the terminal device is located.

[0123] Step S404: Based on the value of the selection factor, determine the HARQ process identifier corresponding to the CG resources in different time units from the HARQ process identifier configured for the CG resources of the terminal device.

[0124] In response to the value of the selection factor being a set value, the set value can be 0, that is, the time unit is determined to be an integer multiple of the HARQ feedback period, then the information transmitted on the time unit corresponding to the CG resource needs to be HARQ feedback, and from the HARQ process identifier configured for the CG resource of the terminal device, the HARQ process identifier corresponding to the time unit is determined to be the first HARQ process identifier in the feedback enabled state.

[0125] In response to the value of the selection factor being non-set value, that is, determining that the time unit is not an integer multiple of the HARQ feedback period, the information transmitted on the time unit corresponding to the CG resource does not require HARQ feedback, and from the HARQ process identifier configured for the CG resource of the terminal device, the HARQ process identifier corresponding to the time unit is determined to be the second HARQ process identifier in the feedback disabled state.

[0126] For example, if the RRC configuration has two HARQ process IDs, such as HARQ process ID#0 has no feedback and HARQ ID#1 has feedback; the SPS PDSCH set is configured to use two HARQ process IDs, and after activation, the HARQ process IDs used by the SPSPDSCH are #0 and #1.

[0127] In the embodiment of the present application, the calculation method of the HARQ process ID is:

[0128]

[0129] Among them, harq-ProcID-Offset is the HARQ process ID offset value configured by RRC. If RRC is not configured, it does not appear.

[0130] Based on the above example, when harq-ProcID-Offset is not configured, the HARQ Process ID of the CG resource on different time units is determined by formula (3), as shown in Table 1. In Table 1, the first SPS PDSCH transmission starts from slot 20.

[0131] Table 1

[0132] slot 20 40 60 80 100 120 140 160 180 200 HARQ process ID 0 0 0 0 1 0 0 0 0 1

[0133] In the embodiment of the present application, the HARQ feedback cycle is 100 slots, and the time unit where the CG resource is located is an integer multiple of the HARQ feedback cycle, that is, the HARQ Process ID of the CG resources corresponding to slots (slot) 100 and slot 200 are both 1#. In the embodiment of the present application, when the value of the selection factor obtained by formula (1) for slots 100 and 200 is 0, it means that the time unit where the CG resource is located is an integer multiple of the HARQ feedback cycle, and the HARQ Process ID corresponding to the CG resource is 1#. Since HARQProcess ID#1 is configured to be in the feedback-enabled state, the terminal device can perform HARQ feedback on the information transmitted on the corresponding CG resource.

[0134] In the embodiment of the present application, the HARQ feedback cycle is 100 slots, and the time unit where the CG resource is located is not an integer multiple of the HARQ feedback cycle, that is, the HARQ Process IDs of the CG resources corresponding to slot 20, slot 40, slot 60, slot 80, slot 120, slot 140, slot 160, and slot 180 are all 0#. In the embodiment of the present application, when the value of the selection factor obtained by slot 20, slot 40, slot 60, slot 80, slot 120, slot 140, slot 160, and slot 180 according to formula (1) is other values, it means that the time unit where the CG resource is located is not an integer multiple of the HARQ feedback cycle, and the HARQ Process ID corresponding to the CG resource is 0#. Since HARQ Process ID#0 is configured to be in a feedback disabled state, the terminal device does not perform HARQ feedback on the information transmitted on the CG resource.

[0135] In some implementations, unlike the first SPS PDSCH transmission starting from slot 20 in Table 1, the first SPS PDSCH transmission can be started from slot 100. Based on the above example, when harq-ProcID-Offset is not configured, the HARQ Process ID of the CG resource on different time units determined by formula (3) is used, as shown in Table 2.

[0136] Table 2

[0137] slot 20 40 60 80 100 120 140 160 180 200 HARQ process ID NA NA NA NA 1 0 0 0 0 1

[0138] Since the first SPS PDSCH transmission has not started in slot 20, slot 40, slot 60, and slot 80, the HARQ process ID is empty. Starting from slot 100, when the first SPS PDSCH transmission starts, the selection factor obtained by slot 100 and slot 200 according to formula (1) is 0, that is, slot 100 and slot 200 are integer multiples of the HARQ feedback period, it can be determined that the HARQ process ID corresponding to slot 100 and slot 200 is 1#. Since HARQ Process ID#1 is configured to be in the feedback-enabled state, the terminal device can perform HARQ feedback on the information transmitted on the corresponding CG resource. When the value of the selection factor obtained by slot 120, slot 140, slot 160, and slot 180 according to formula (1) is other value others, that is, slot 120, slot 140, slot 160, and slot 180 are not integer multiples of the HARQ feedback cycle, it can be determined that the HARQ process ID corresponding to slot 120, slot 140, slot 160, and slot 180 is 0#. Since HARQ Process ID#0 is configured to be in a feedback disabled state, the terminal device does not perform HARQ feedback on the information transmitted on the CG resource.

[0139] In the embodiment of the present application, by introducing the HARQ feedback cycle, the contradiction between the SPS PDSCH cycle and the HARQ process ID can be coordinated, thereby improving the speed and quality of data transmission, improving the flexibility of data transmission, and avoiding data transmission errors.

[0140] See Figure 5 , Figure 5 This is a flow chart of a HARQ feedback method for CG resources provided in an embodiment of the present application. Figure 5 As shown, the method may include but is not limited to the following steps:

[0141] Step 501: Determine the HARQ feedback cycle corresponding to the CG resource.

[0142] Regarding the implementation of step S501, please refer to any implementation in the embodiments of this application, and will not be repeated here.

[0143] Step 502: In response to the fact that the HARQ process identifier is not configured for the CG resource of the terminal device, HARQ feedback is reported to the network device once every set time interval.

[0144] In response to the fact that a HARQ process identifier is not configured for the CG resource of the terminal device, it is impossible to determine whether to perform HARQ feedback on information transmitted in a time unit corresponding to the CG resource based on feedback enable information of the HARQ process identifier. Optionally, HARQ feedback may be reported to the network device once every set time interval. The set time interval is greater than the minimum RTT.

[0145] In an embodiment of the present application, by reporting HARQ feedback to the network device once at a set interval, the terminal device can perform error control on the transmitted data within the set time range, thereby increasing data transmission reliability and improving data transmission efficiency.

[0146] See Figure 6 , Figure 6 This is a flow chart of a HARQ feedback method for CG resources provided in an embodiment of the present application. Figure 6 As shown, the method may include but is not limited to the following steps:

[0147] Step S601: In response to the CG resource not being configured with a HARQ feedback period, the HARQ process identifier corresponding to the CG resource is determined based on the period of the CG resource and other RRC parameters.

[0148] HARQ Process ID=[floor(CURRENT slot ×N / (SPF×periodicity))]modulo(nrofHARQ-Processes)+harq-ProcID-Offset (4)

[0149] Among them, periodicity is the period of CG resources configured by RRC, nrofHARQ-Processes is the number of HARQ processes configured by SPS PDSCH, floor is the maximum integer returned that is less than or equal to a preset value, and harq-ProcID-Offset is the HARQ process ID offset value configured by RRC. If RRC is not configured, it will not appear. In the embodiment of the present application, CURRENT slot =(SFN×SPF)+slot number in the frame, SPF is the number of consecutive time slots in each frame, SFN is the system frame number, and slot number in the frame is the time slot number where the SPS PDSCH is currently received.

[0150] Table 3

[0151] slot 20 40 60 80 100 120 140 160 180 200 HARQ process ID 1 0 1 0 1 0 1 0 1 0

[0152] As shown in Table 3, for example, in an embodiment of the present application, the HARQ feedback cycle is 20, and the time unit where the CG resource is located is the same as the HARQ feedback cycle, that is, the HARQ Process ID of the CG resources corresponding to slot 20, slot 60, slot 100, slot 140, and slot 180 are all 1#. In an embodiment of the present application, slot 100 and slot 200 obtain the HARQ Process ID corresponding to the CG resource as 1# according to formula (4). Since HARQ Process ID#1 is configured to be in a feedback-enabled state, the terminal device can perform HARQ feedback on the information transmitted on the corresponding CG resource. The HARQ Process ID of the CG resources corresponding to slot 40, slot 80, slot 120, slot 160, and slot 200 are all 0#. In an embodiment of the present application, slot 100 and slot 200 obtain the HARQ Process ID corresponding to the CG resource as 0# according to formula (4). Since HARQ Process ID#0 is configured to be in a feedback disabled state, the terminal device does not perform HARQ feedback for the information transmitted on the CG resource.

[0153] In an embodiment of the present application, the terminal device can perform error control on the transmitted data within a set time range, improve the flexibility of data transmission, avoid data transmission errors, thereby increasing data transmission reliability and improving data transmission efficiency.

[0154] See Figure 7 , Figure 7 This is a flow chart of a HARQ feedback method for CG resources provided in an embodiment of the present application, which is executed by a network device. Figure 7 As shown, the method may include but is not limited to the following steps:

[0155] Step 701, configure the HARQ feedback cycle corresponding to the CG resources.

[0156] In some implementations, the HARQ feedback period corresponding to the CG resource can be configured according to the protocol agreement. In some implementations, the HARQ feedback period corresponding to the CG resource can be configured based on the service characteristics supported by the terminal device. In the present application, the HARQ feedback period can be the time interval between two consecutive times that the HARQ process corresponding to the same HARQ process ID in the feedback-enabled state is used by the CG resource. It should be noted that, in order to determine the HARQ process ID, the HARQ feedback period parameter is newly introduced in the present application, and the HARQ process ID is determined based on the HARQ feedback period parameter.

[0157] Step 702: Determine whether to receive HARQ feedback from the terminal device for information transmitted on the CG resource based on the HARQ feedback cycle.

[0158] In some implementations, after configuring the HARQ feedback period corresponding to the CG resource, the HARQ process ID corresponding to the CG resource can be determined based on the HARQ feedback period and a preset policy. Furthermore, based on the HARQ process ID corresponding to the CG resource, it is determined whether to receive HARQ feedback from the terminal device for information transmitted on the CG resource.

[0159] Optionally, in response to the HARQ process ID corresponding to the CG resource being in a feedback-enabled state, the HARQ feedback of the receiving terminal device on the information transmitted on the CG resource is determined.

[0160] Optionally, in response to the HARQ process ID corresponding to the CG resource being in a feedback disabled state, it is determined not to receive HARQ feedback from the terminal device for information transmitted on the CG resource.

[0161] In an embodiment of the present application, a HARQ feedback period corresponding to a CG resource is configured, and based on the HARQ feedback period, it is determined whether to receive HARQ feedback from a terminal device for information transmitted on the CG resource. Thus, by introducing the HARQ feedback period to determine the HARQ process ID, the determination of the HARQ process ID is decoupled from the SPS PDSCH period, and the conflict between the SPS PDSCH period and the HARQ process ID can be reconciled, thereby improving the speed and quality of data transmission, increasing the flexibility of data transmission, and avoiding data transmission errors.

[0162] See Figure 8 , Figure 8 This is a flow chart of a HARQ feedback method for CG resources provided in an embodiment of the present application, which is executed by a network device. Figure 8 As shown, the method may include but is not limited to the following steps:

[0163] Step 801: configure the HARQ feedback cycle corresponding to the CG resources.

[0164] Regarding the implementation of step S801, please refer to any implementation in the embodiments of this application, and will not be repeated here.

[0165] Step 802: Determine the HARQ process identifier corresponding to the CG resources in different time slots according to the HARQ feedback cycle.

[0166] In some implementations, the network device configures a HARQ process ID for the CG resources of the terminal device based on protocol agreements or service features supported by the terminal device. Typically, the HARQ process ID corresponding to the CG resource is configured through RRC signaling. Optionally, the network device configures the HARQ process ID for the CG resources of the terminal device and can send RRC configuration information to the terminal device. In some implementations, the configuration information includes feedback enabling information for the HARQ process ID and / or the HARQ process ID configured for the terminal device.

[0167] In some implementations, the configuration information includes a HARQ process identifier configured for the CG resource of the terminal device, and feedback enable information of the HARQ process identifier can be confirmed based on the HARQ process identifier. For example, the network device can determine the maximum number of HARQ process IDs that can be indicated in the DCI based on the capability of the terminal device. If the capability of the terminal device is 32, the maximum number of HARQ process IDs that can be indicated in the DCI is 32. That is, the network device configures 32 HARQ process IDs through RRC, where the feedback enable information of HARQ process ID#0 to 15 indicates that the HARQ process identifier is in a feedback disabled state, and the feedback enable information of HARQ process ID#16 to 31 indicates that the HARQ process identifier is in a feedback enabled state.

[0168] In some implementations, the configuration information includes a HARQ process identifier configured for the CG resources of the terminal device and feedback enabling information of the HARQ process identifier. In some implementations, the configuration information includes feedback enabling information of the HARQ process identifier configured for the terminal device.

[0169] After configuring the HARQ feedback cycle, the HARQ process ID corresponding to the CG resource can be determined based on the HARQ feedback cycle and a preset strategy.

[0170] Step 803: Based on the feedback enabling information of the HARQ process identifier, determine whether to receive HARQ feedback from the terminal device for the information transmitted on the time unit corresponding to the CG resource.

[0171] The network device can send the information transmitted on the CG resource to the terminal device. In an embodiment of the present application, after sending the information, the network device determines whether to receive the HARQ feedback of the terminal device for the information transmitted on the time unit corresponding to the CG resource based on the HARQ process ID corresponding to the CG resource. In some implementations, if the feedback enable information of the HARQprocess ID corresponding to the CG resource indicates that the HARQ process ID is in a feedback-enabled state, the terminal device can perform HARQ feedback on the information transmitted on the time unit corresponding to the CG resource on the HARQ process identified by the HARQ process ID, that is, the network device receives the HARQ feedback of the terminal device for the information received from the CG resource. For example, if the determined HARQ process ID corresponding to the CG resource is #16 or #17, then the network device receives the HARQ feedback of the terminal device for the information transmitted on the time unit corresponding to the CG resource.

[0172] In some implementations, if the feedback enable information for the HARQ process ID corresponding to the CG resource indicates that the HARQ process ID is in a feedback disabled state, the terminal device does not perform HARQ feedback on the HARQ process identified by the HARQ process ID for information transmitted in the time unit corresponding to the CG resource, and the network device does not receive HARQ feedback from the terminal device for information received from the CG resource. For example, if the determined HARQ process ID corresponding to the CG resource is #0 or #1, the network device does not receive HARQ feedback from the terminal device for information transmitted in the time unit corresponding to the CG resource. For example, if the determined HARQ process ID corresponding to the CG resource is #15 or #16, the network device partially receives and partially does not receive the HARQ feedback of the terminal device on the information transmitted on the time unit corresponding to the CG resource. That is to say, if the determined HARQ process ID corresponding to the CG resource is #15, the network device does not receive the HARQ feedback of the terminal device on the information transmitted on the time unit corresponding to the CG resource. If the determined HARQ process ID corresponding to the CG resource is #16, the network device receives the HARQ feedback of the terminal device on the information transmitted on the time unit corresponding to the CG resource.

[0173] In an embodiment of the present application, the HARQ process identifier corresponding to the CG resources on different time slots is determined based on the HARQ feedback cycle, and based on the feedback enable information of the HARQ process identifier, it is determined whether to receive HARQ feedback from the terminal device for the information transmitted on the time unit corresponding to the CG resource. In an embodiment of the present application, the HARQ process ID is determined by introducing a HARQ feedback cycle, so that the determination of the HARQ process ID is untied from the SPS PDSCH cycle, and the contradiction between the SPS PDSCH cycle and the HARQ process ID can be coordinated, which can improve the speed and quality of data transmission, improve the flexibility of data transmission, and avoid data transmission errors.

[0174] See Figure 9 , Figure 9 This is a flow chart of a HARQ feedback method for CG resources provided in an embodiment of the present application, which is executed by a network device. Figure 9 As shown, the method may include but is not limited to the following steps:

[0175] Step 901, configure the HARQ feedback cycle corresponding to the CG resources.

[0176] Regarding the implementation of step S901, please refer to any implementation in the embodiments of this application, and will not be repeated here.

[0177] Step 902: Determine the time unit where the currently sent CG resource is located.

[0178] In some implementations, the CG resource is a downlink CG resource, namely, SPS PDSCH, and the time unit is the time slot where the currently transmitted CG resource is located.

[0179] In some implementations, the CG resource is an uplink CG resource, namely Type-1 CG and Type-2 CG, and the time unit is the symbol where the currently transmitted CG resource is located.

[0180] Step 903: Determine the value of the selection factor based on the time unit and the HARQ feedback cycle.

[0181] In response to the CG resource being a downlink CG resource, a first parameter is determined based on a time unit, a second parameter is determined based on the number of consecutive time slots per frame and the HARQ feedback period, and a remainder between the first parameter and the second parameter is obtained as the value of the selection factor. For example, the product of the time slot number where the CG resource sent by the network device is located and a preset threshold is used as the first parameter, and the product of the number of consecutive time slots per frame and the HARQ feedback period is used as the second parameter, and the selection factor is confirmed based on formula (1) in the above embodiment.

[0182] In response to the CG resource being an uplink CG resource, a remainder between the time unit and the feedback period is obtained as a value of the selection factor. For example, the selection factor is determined based on formula (2) in the above embodiment.

[0183] Step 904: Based on the value of the selection factor, determine the HARQ process identifier corresponding to the CG resources in different time units from the HARQ process identifier configured for the CG resources of the terminal device.

[0184] In response to the value of the selection factor being a set value, the set value may be 0, that is, the time unit is determined to be an integer multiple of the HARQ feedback period, and then the HARQ feedback of the receiving terminal device on the information transmitted on the CG resource is determined, from the HARQ process identifier configured for the CG resource of the terminal device, to be the first HARQ process identifier in the feedback enabled state.

[0185] In response to the value of the selection factor being non-set value, that is, determining that the time unit is not an integer multiple of the HARQ feedback period, the HARQ feedback of the terminal device on the information transmitted on the CG resource is not received, and from the HARQ process identifier configured for the CG resource of the terminal device, the HARQ process identifier corresponding to the time unit is determined to be the second HARQ process identifier in the feedback disabled state.

[0186] For example, if the RRC configures two HARQ process IDs, such as HARQ process ID#0 does not receive HARQ feedback from the terminal device on the information transmitted on the CG resources, and HARQ ID#1 receives HARQ feedback from the terminal device on the information transmitted on the CG resources; the SPS PDSCH set is configured to use two HARQ process IDs, and after activation, the HARQ process IDs used by the SPS PDSCH are #0 and #1.

[0187] In the embodiment of the present application, the calculation method of the HARQ process ID may be formula (3) in the above embodiment.

[0188] Based on the above example, when harq-ProcID-Offset is not configured, the HARQ Process ID of the CG resource on different time units is determined by formula (3), as shown in Table 1 in the above embodiment. In Table 1, the first SPS PDSCH transmission starts from slot 20.

[0189] In the embodiment of the present application, the HARQ feedback cycle is 100 slots, and the time unit where the CG resource is located is an integer multiple of the HARQ feedback cycle, that is, the HARQ Process ID of the CG resources corresponding to slots (slot) 100 and slot 200 are both 1#. In the embodiment of the present application, when the value of the selection factor obtained by formula (1) for slots 100 and 200 is 0, it means that the time unit where the CG resource is located is an integer multiple of the HARQ feedback cycle, and the HARQ Process ID corresponding to the CG resource is 1#. Since HARQProcess ID#1 is configured to be in a feedback-enabled state, the network device can receive HARQ feedback from the terminal device on the information transmitted on the CG resource.

[0190] In the embodiment of the present application, the HARQ feedback cycle is 100 slots, and the time unit where the CG resource is located is not an integer multiple of the HARQ feedback cycle, that is, the HARQ Process IDs of the CG resources corresponding to slot 20, slot 40, slot 60, slot 80, slot 120, slot 140, slot 160, and slot 180 are all 0#. In the embodiment of the present application, when the value of the selection factor obtained by slot 20, slot 40, slot 60, slot 80, slot 120, slot 140, slot 160, and slot 180 according to formula (1) is other values ​​others, it means that the time unit where the CG resource is located is not an integer multiple of the HARQ feedback cycle, and the HARQ Process ID corresponding to the CG resource is 0#. Since HARQ Process ID#0 is configured to be in a feedback disabled state, the network device does not receive HARQ feedback from the terminal device on the information transmitted on the CG resource.

[0191] In some implementations, instead of starting the first SPS PDSCH transmission from slot 20 as shown in Table 1, the first SPS PDSCH transmission can start from slot 100. Based on the above example, if harq-ProcID-Offset is not configured, the HARQ Process ID of the CG resource at different time units is determined using formula (3).

[0192] As shown in Table 2 in the above embodiment, since the first SPS PDSCH transmission has not started in slot 20, slot 40, slot 60, and slot 80, the HARQ process ID is empty. When the first SPS PDSCH transmission starts from slot 100, when the value of the selection factor obtained by slot 100 and slot 200 according to formula (1) is 0, that is, slot 100 and slot 200 are integer multiples of the HARQ feedback period, it can be determined that the HARQ process ID corresponding to slot 100 and slot 200 is 1#. Since HARQ Process ID#1 is configured to be in the feedback-enabled state, the network device receives the HARQ feedback of the terminal device for the information transmitted on the CG resource. When the value of the selection factor obtained by slot 120, slot 140, slot 160, and slot 180 according to formula (1) is other value others, that is, slot 120, slot 140, slot 160, and slot 180 are not integer multiples of the HARQ feedback period, it can be determined that the HARQ process ID corresponding to slot 120, slot 140, slot 160, and slot 180 is 0#. Since HARQ Process ID#0 is configured to be in a feedback disabled state, the network device does not receive HARQ feedback from the terminal device for the information transmitted on the CG resource.

[0193] In the embodiment of the present application, by introducing the HARQ feedback cycle, the contradiction between the SPS PDSCH cycle and the HARQ process ID can be coordinated, thereby improving the speed and quality of data transmission, improving the flexibility of data transmission, and avoiding data transmission errors.

[0194] See Figure 10 , Figure 10 This is a flow chart of a HARQ feedback method for CG resources provided in an embodiment of the present application, which is executed by a network device. Figure 10 As shown, the method may include but is not limited to the following steps:

[0195] Step 1001, configure the HARQ feedback cycle corresponding to the CG resource.

[0196] Regarding the implementation method of step S1001, please refer to any implementation method in the embodiments of this application, and will not be repeated here.

[0197] Step 1002: In response to the fact that the HARQ process identifier is not configured for the CG resource of the terminal device, the terminal device reports a HARQ feedback once every set time interval.

[0198] In response to not configuring a HARQ process identifier for the CG resource of the terminal device, it is impossible to determine whether to receive HARQ feedback from the terminal device for information transmitted on the CG resource based on the feedback enable information of the HARQ process identifier. Optionally, the HARQ feedback reported by the terminal device can be received once every set time interval. The set time interval is greater than the minimum RTT time interval.

[0199] In an embodiment of the present application, by receiving a HARQ feedback report from a terminal device at an interval set for a period of time, the network device can perform error control on the transmission data within the set period of time, thereby increasing data transmission reliability and improving data transmission efficiency.

[0200] See Figure 11 , Figure 11 This is a flow chart of a HARQ feedback method for CG resources provided in an embodiment of the present application, which is executed by a network device. Figure 11 As shown, the method may include but is not limited to the following steps:

[0201] Step 1101: In response to the CG resource not being configured with a HARQ feedback period, the HARQ process identifier corresponding to the CG resource is determined based on the period of the CG resource and other RRC parameters.

[0202] In some implementations, the formula (4) in the above facts can be used for calculation, as shown in Table 3 in the above embodiment. For example, in the embodiment of the present application, the HARQ feedback cycle is 20, and the time unit where the CG resource is located is the same as the HARQ feedback cycle, that is, the HARQ Process ID of the CG resources corresponding to slot 20, slot 60, slot 100, slot 140, and slot 180 is all 1#. In the embodiment of the present application, the HARQ Process ID corresponding to the CG resource obtained by slot 100 and slot 200 according to formula (4) is 1#. Since HARQ Process ID#1 is configured to be in a feedback-enabled state, the network device receives the HARQ feedback of the terminal device on the information transmitted on the CG resource. The HARQ Process ID of the CG resources corresponding to slot 40, slot 80, slot 120, slot 160, and slot 200 is all 0#. In the embodiment of the present application, the HARQ Process ID corresponding to the CG resource obtained by slot 100 and slot 200 according to formula (4) is 0#. Since HARQ Process ID#0 is configured to be in a feedback disabled state, the network device does not receive HARQ feedback from the terminal device for information transmitted on the CG resource.

[0203] In an embodiment of the present application, the terminal device can perform error control on the transmitted data within a set time range, improve the flexibility of data transmission, avoid data transmission errors, thereby increasing data transmission reliability and improving data transmission efficiency.
