Abstract

The present application provides a method, apparatus, device and storage medium for determining a HARQ process ID, wherein the configuration parameters sent by a network device to a terminal device include the number of consecutive time slots in the same cycle, and the number of consecutive time slots indicates the number of time slots continuously allocated at transmission opportunities in the cycle. When the terminal device determines the HARQ process ID based on the number of consecutive time slots in the same cycle, it can ensure that the IDs of different HARQ processes are different. Therefore, the corresponding HARQ process can be uniquely determined based on one HARQ process ID, thereby avoiding the occurrence of HARQ process ID conflicts, thereby facilitating retransmission and ensuring normal communication between the network device and the terminal device.

[0002] In the 5G New Radio (NR) system, the network equipment can pre-configure uplink (UL) resources or downlink (DL) resources for the terminal equipment (UE) so that the UE can transmit data in parallel through multiple hybrid automatic repeat request (HARQ) processes according to the resource location configured by the network equipment, so as to be suitable for periodic services, such as Voice over Internet Protocol (VoIP) services based on IP, or certain Ultra-Reliable and Low Latency Communications (URLLC) services with periodic control signaling and other services.

[0003] However, when multi-slot scheduling is configured, when calculating the HARQ process identity document (ID), the existing calculation method will cause the HARQ process ID duplication problem, which will lead to the problem of unable to retransmit for application scenarios that require retransmission.

[0103] Figure 1 The following is a schematic diagram of the architecture of a wireless communication system provided in an embodiment of the present application. Figure 1 As shown, the wireless communication system may include: a network device 12 and a terminal device 11, and the terminal device 11 may communicate (transmit signaling or transmit data) with the network device 12. In practical applications, the above-mentioned devices are wirelessly connected via a network.

[0104] Among them, the network device can be a base station, specifically a base station (Base Transceiver Station, BTS) and / or a base station controller in Global System of Mobile communication (GSM) or Code Division Multiple Access (CDMA), or a base station (NodeB, NB) and / or a radio network controller (Radio Network Controller, RNC) in Wideband Code Division Multiple Access (WCDMA), or an evolved base station (Evolutional Node B, eNB or eNodeB) in Long Term Evolution (LTE), or a relay station or access point, or a base station (gNB) in a 5G network, etc. The embodiments of the present application are not limited here.

[0105] The terminal device can be a wireless terminal or a wired terminal. The wireless terminal can be a device that provides voice and / or other business data connectivity to users, a handheld device with wireless connection function, or other processing equipment connected to a wireless modem. The wireless terminal can communicate with one or more core network devices via the Radio Access Network (RAN). The wireless terminal can be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal. For example, it can be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device that exchanges language and / or data with the wireless access network. For another example, the wireless terminal can also be a Personal Communication Service (PCS) phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA) and other devices. The wireless terminal may also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, a remote terminal, an access terminal, a user terminal, a user agent, a user device or user equipment, without limitation. Optionally, the terminal device may also be a smart watch, a tablet computer or other device.

[0106] For ease of understanding, the basic definitions of the terms involved in the embodiments of the present invention are explained below:

[0107] In the terms involved in the technical solution of the present application, the number of time slots in a wireless frame indicates the number of consecutive time slots in each system frame. For example, when the subcarrier interval is 15KHz, a system frame contains 10 time slots; the number of symbols in a time slot indicates the number of consecutive symbols in each time slot. For example, in a normal cyclic prefix, there are 14 symbols in a time slot; the time slot transmission sequence number in a wireless frame indicates the sequence number of a wireless frame time slot during the transmission process, such as the 0th time slot, the 1st time slot, etc.; the symbol sequence number in a time slot indicates the sequence number of a time slot symbol during the transmission process, such as the 0th symbol, the 1st symbol. SFN indicates the system frame number corresponding to the system frame during the transmission process; the configuration authorization period is the period in which the configuration authorization occurs, such as 10ms, etc. The current time slot / current symbol is the first sending time of repeated data transmission when the current configuration authorization transmission is repeated transmission; the number of HARQ processes in the configuration authorization is the number of HARQ processes reserved in the configuration authorization, for example, the network device reserves 8 HARQ processes for the configuration authorization, which is expressed as the number of UL HARQ processes reserved in the configuration authorization. The semi-static scheduling period is the period in which semi-static scheduling occurs, such as 20ms. The current time slot / current symbol is the first receiving time of repeated data transmission when the current semi-static scheduling transmission is repeated transmission; the number of HARQ processes in the semi-static scheduling is the number of HARQ processes reserved in the semi-static scheduling, for example, the network device reserves 6 HARQ processes for semi-static scheduling, which is expressed as the number of DL HARQ processes reserved in semi-static scheduling.

[0108] Configured Grant (CG) is different from dynamic scheduling, which allocates wireless resources to terminal devices once per time slot / transmission time interval (TTI) (specified by the Physical Downlink Control Channel (PDCCH)). Configured Grant allows semi-persistent scheduling (SPS) to configure wireless resources and periodically allocate the resources to a specific terminal device.

[0109] Simply put, the network device notifies the terminal device that it can periodically use a certain resource. Optionally, the location of the periodic resource can be notified through Radio Resource Control (RRC) signaling. Optionally, the network device can also notify the terminal device of the frequency domain location, start and end time, modulation coding scheme (MCS) and other information of the resource to be used. In this way, the network device reduces the PDCCH notification overhead through periodic resource allocation.

[0110] Configuring the authorization scheduling mode is applicable to periodic services, such as VoIP services, or services with periodic control signaling in some URLLC services.

[0111] Configuration authorization is an uplink scheduling method. There are two types of methods: type 1 and type 2.

[0112] In Type 1: RRC allocates periodic resources, and after RRC configuration, the resources are in an activated state, that is, the terminal device can use the resources to send uplink data after receiving the RRC configuration message;

[0113] In Type2: RRC allocates periodic resources, but the initial state is inactive. The network device needs to activate the resource through physical layer signaling. After the data transmission is completed, the resource is deactivated through downlink control information (DIC). Similarly, the configuration information of some configuration authorizations can also be modified through physical layer signaling, such as modifying the time-frequency domain location information of the resource.

[0114] In the prior art, the HARQ process ID is calculated in the following way:

[0115] (1) For downlink (DL)

[0116] HARQ Process ID=[floor(CURRENT_slot×10 / (numberOfSlotsPerFrame×periodicity))]%nrofHARQ-Processes

[0117] CURRENT_slot=[(SFN×numberOfSlotsPerFrame)+slot number in the frame]

[0121] numberOfSlotsPerFrame indicates the number of consecutive time slots in a frame;

[0124] SFN means system frame number;

[0125] The slot number in the frame indicates the sequence number of the time slot during transmission.

[0126] (2) For uplink (UL)

[0127] HARQ Process ID=[floor(CURRENT_symbol / periodicity)]%nrofHARQ-Processes

[0128] CURRENT_symbol=(SFN×numberOfSlotsPerFrame×numberOfSymbolsPerSlot+slot number in the frame×numberOfSymbolsPerSlot+symbol number in the slot)

[0129] Wherein, HARQ Process ID represents the HARQ process ID;

[0130] CURRENT_symbol represents the current symbol;

[0131] Periodicity indicates the configuration authorization period;

[0132] nrofHARQ-Processes configures the number of authorized HARQ processes;

[0133] SFN means system frame number;

[0137] numberOfSymbolsPerSlot represents the number of symbols in a time slot;

[0138] symbol number in the slot indicates the symbol sequence number in the time slot.

[0139] In order to improve throughput and reduce the problem of data packets being unable to be sent due to Listen Before Talk (LBT) failure or resource conflicts, the prior art introduces multi-slot scheduling, which defines multiple sending opportunities on a set of configuration grants and mainly defines two parameters:

[0140] 1)cg-nrofSlots: indicates the number of time slots that a CG transmitter can continuously allocate within a CG authorization period.

[0141] 2)cg-nrofPUSCH-InSlot: indicates the number of consecutive physical uplink shared channels (PUSCH) allocated in one time slot.

[0142] Specifically, the case where cg-nrofSlots=4 and cg-nrofPUSCH-InSlot=2 is taken as an example for explanation. Figure 2 Schematic diagram of the time domain in a multi-transport block (TB) scenario in an embodiment of the present application, such as Figure 2 As shown, cg-nroSlots=4, indicating that there are 4 consecutive time slots; cg-nroPUSCH-InSlot=2, indicating that there are two consecutive uplink authorizations in one time slot, wherein the starting position of the first uplink authorization is symbol S=2, and the symbol length L=4.

[0143] During the communication between the terminal device and the network device, both parties perform data verification based on a cyclic redundancy check (CRC) to determine whether retransmission is required.

[0144] Specifically, the sender uses the data in the data block TB to calculate CRC1, and sends CRC1 to the receiver along with the TB. The receiver calculates CRC2 based on the received data, and compares CRC2 with the received CRC1. If the two are equal, the receiver determines that the correct data has been received and sends an acknowledgement message (Acknowledgement, ACK) to the sender; if the two are not equal, the receiver believes that the wrong data has been received, and sends a negative acknowledgement message (NegativeAcknowledgement, NACK) to the sender, and asks the sender to retransmit the TB. In addition, if the sender does not receive a reply from the receiver within the specified time, it is considered that the transmission has failed and the TB will be automatically retransmitted.

[0145] During the retransmission process, the transmitter needs to know the HARQ process ID corresponding to the TB that needs to be retransmitted. Therefore, for each TB sent by the transmitter, the corresponding HARQ process ID needs to be determined.

[0146] Taking the uplink as an example, the calculation formula of the HARQ process ID is:

[0147] HARQ Process ID=[floor(CURRENT_symbol / periodicity)]modulo nrofHARQ-Processes

[0148] CURRENT_symbol=(SFN×numberOfSlotsPerFrame×numberOfSymbolsPerSlot+slot number in the frame×numberOfSymbolsPerSlot+symbol number in the slot),

[0149] In addition, if multiple sets of configuration authorization are considered, the formula is expressed as:

[0150] HARQ Process ID=[floor(CURRENT_symbol / periodicity)]modulo nrofHARQ-Processes+harq-ProcID-Offset

[0151] Among them, harq-ProcID-Offset represents the authorization parameters in multiple configurations. It can be understood that if multiple configuration authorizations are not configured, this parameter may not be present.

[0152] Assuming that the current subcarrier spacing (SCS) is 15KHz, the non-extended cyclic prefix (CP), the configuration authorization period of the CG is 10 time slots, that is:

[0153] numberOfSymbolsPerSlot=14

[0154] numberOfSlotsPerFrame = 10

[0155] SFN=1

[0156] slot number in the frame=1

[0157] symbol number in the slot=2

[0158] Configure the number of HARQ processes reserved for authorization to be 12 and the number of consecutive time slots to be 4.

[0159] Based on the calculation formula of the prior art, the HARQ process IDs of the two CG resources in the same CG cycle are:

[0160] CURRENT_symbol=(SFN×numberOfSlotsPerFrame×numberOfSymbolsPerSlot+slot number in the frame×numberOfSymbolsPerSlot+symbol number in the slot)

[0161] =(1*10*14+1*14+2)=156

[0162] Periodicity=10slot=10*14symbol=140symbol

[0163] HARQ Process ID=[floor(CURRENT_symbol / periodicity)]modulo nrofHARQ-Processes=[floor(156 / 140)]modulo 12=1

[0164] Figure 3 This is another time domain schematic diagram in a multi-TB scenario in an embodiment of the present application, referring to Figure 3 If the number of configured continuous time slots is 4, since the concept of continuous time slots is not considered in the existing calculation formula, the results of HARQ process IDs are the same and cannot be distinguished. When retransmission is required, since multiple HARQ process IDs are the same, it will be impossible to determine which HARQ process TB needs to be retransmitted, resulting in a situation where retransmission cannot be performed.

[0165] The HARQ process ID determination method, apparatus, device and storage medium provided in the present application are intended to solve the above technical problems in the prior art.

[0166] In an embodiment of the present application, the configuration parameters sent by the network device to the terminal device include the number of consecutive time slots in the same cycle, which represents the number of consecutive time slots allocated at the transmission opportunity in the cycle. For example, Figure 2 As shown in the schematic diagram, within a single time slot (i.e., between two time slot boundaries), each time slot includes two consecutive uplink grants, and each uplink grant corresponds to a transmission opportunity, such as uplink grant #0, uplink grant #1, uplink grant #2, uplink grant #3, etc. Figure 3 Same reason.

[0167] When the terminal device determines the HARQ process ID based on the number of consecutive time slots in the same cycle, it can ensure that the HARQ process IDs corresponding to different transmission timings are different. Therefore, based on one HARQ process ID, the transmission timing of the corresponding HARQ process can be uniquely determined, avoiding the occurrence of HARQ process ID conflicts, thereby facilitating retransmission and ensuring normal communication between the network device and the terminal device.

[0168] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0169] It can be understood that for the sake of ease of explanation, the description of "cycle" and "single time slot" in this application can be adaptively adjusted. For example, "cycle" can also be described as "the same cycle", and "single time slot" can also be described as "the same time slot", etc.

[0170] Figure 4 A schematic diagram of a method for determining a HARQ process ID provided in an embodiment of the present application is shown in FIG. Figure 4 As shown, the method mainly includes the following steps:

[0171] S401. The network device determines a configuration parameter, where the configuration parameter includes the number of consecutive time slots in the same cycle, where the number of consecutive time slots is used to indicate the number of consecutively allocated time slots at transmission opportunities in the cycle;

[0172] S402. The network device sends a notification message including configuration parameters to the terminal device, where the notification message is used to instruct the terminal device to determine a HARQ process ID corresponding to a transmission opportunity based on the number of consecutive time slots in the same cycle.

[0173] S403, the terminal device receives the configuration parameters sent by the network device, where the configuration parameters include the number of consecutive time slots in the same cycle, where the number of consecutive time slots is used to indicate the number of consecutively allocated time slots at the transmission opportunity in the cycle;

[0174] S404: The terminal device determines the HARQ process ID corresponding to the transmission opportunity based on the number of consecutive time slots in the same cycle.

[0175] Specifically, the configuration parameters sent by the network device to the terminal device include the number of consecutive time slots in the same cycle, and the number of consecutive time slots indicates the number of time slots continuously allocated at the transmission opportunities in the cycle. The differences between the present application and the prior art include: in the process of calculating the HARQ process ID, the present application takes the number of consecutive time slots in the same cycle into consideration as a calculation factor. Therefore, when the terminal device determines the HARQ process ID based on the number of consecutive time slots in the same cycle, it can ensure that the IDs of different HARQ processes are different. Therefore, the corresponding HARQ process can be uniquely determined based on a HARQ process ID, thereby avoiding the occurrence of HARQ process ID conflicts, thereby facilitating retransmission and ensuring normal communication between the network device and the terminal device.

[0176] In some embodiments, the period includes a configuration authorization period in the uplink and / or a semi-static scheduling period in the downlink, that is, the number of consecutive time slots in the same period includes the number of consecutive time slots in the same configuration authorization period in the uplink and / or the number of consecutive time slots in the same semi-static scheduling period in the downlink;

[0177] Correspondingly, the terminal device determines the HARQ process ID corresponding to the transmission opportunity based on the number of consecutive time slots in the same cycle, including:

[0178] The terminal device determines the uplink HARQ process ID based on the number of consecutive time slots in the same configured authorization period in the uplink, and / or the terminal device determines the downlink HARQ process ID based on the number of consecutive time slots in the same half of the static scheduling period in the downlink.

[0179] Specifically, the data transmission between the terminal device and the network device includes two modes: uplink and downlink. Therefore, the number of consecutive time slots in the same cycle includes the number of consecutive time slots in the same configuration authorization cycle in the uplink and / or the number of consecutive time slots in the same half of the static scheduling cycle in the downlink. Thus, the terminal device can determine the uplink or downlink HARQ process ID based on the above two numbers of consecutive time slots.

[0180] Compared with the calculation formula of the prior art, the present application determines the HARQ process ID by combining the number of consecutive time slots in the same configuration authorization period in the uplink and / or the number of consecutive time slots in the same SPS period in the downlink, which can ensure that the results of each HARQ process ID are different, avoid HARQ process ID conflicts, and thus distinguish each HARQ process.

[0181] Preferably, in an embodiment of the present invention, the configuration parameters include the number of consecutive time slots within a cycle, wherein the number of consecutive time slots corresponds to the same cycle; the number of consecutive time slots is used to indicate the number of consecutively allocated time slots on the transmission opportunities within the cycle, wherein the transmission opportunities may correspond to the same transmission opportunity or to multiple transmission opportunities.

[0182] The following is an explanation of the process of determining the HARQ process ID during uplink transmission.

[0183] In some embodiments, when the HARQ process is an uplink transmission UL process, the number of consecutive time slots in the same period sent by the network device to the terminal device includes the number of consecutive time slots in the same configured grant period in the uplink;

[0184] In addition, the configuration parameters also include: the number of consecutive UL grants allocated in the same time slot, wherein the number of consecutive UL grants allocated in the same time slot is used to indicate the number of consecutive physical uplink shared channels PUSCH allocated in one time slot;

[0185] Correspondingly, the terminal device determines the uplink HARQ process ID based on the number of consecutive time slots in the same configured authorization period in the uplink, including: the terminal device determines the uplink HARQ process ID based on the number of consecutive time slots in the same configured authorization period in the uplink and the number of consecutive UL authorizations allocated in the same time slot.

[0186] Therefore, the terminal device determines the uplink HARQ process ID based on the number of consecutive time slots in the same configured authorization period in the uplink and the number of consecutive UL authorizations allocated in the same time slot, which can ensure that the results of each HARQ process ID are different, avoid HARQ process ID conflicts, and thus distinguish each HARQ process.

[0187] In some embodiments, the configuration parameters also include: configuring the authorization period, configuring the number of authorized HARQ processes.

[0188] Correspondingly, the terminal device determines the uplink HARQ process ID based on the number of consecutive time slots in the same configured authorization period in the uplink and the number of consecutive UL authorizations allocated in the same time slot, including:

[0189] The terminal device determines the system frame number, the number of time slots in a frame, the number of symbols in a time slot, the time slot sequence number in a frame, the symbol sequence number in a time slot, and the index number of consecutive UL grants in the same configured grant period;

[0190] Among them, the system frame number, the number of time slots in a frame, the number of symbols in a time slot, the time slot sequence number in the frame, the symbol sequence number in the time slot, and the index number of consecutive UL authorizations in the same configuration authorization period can be determined by the terminal device itself.

[0191] The terminal device determines the uplink HARQ process ID based on the number of consecutive time slots in the same configured authorization period in the uplink, the configured authorization period, the number of consecutive UL authorizations allocated in the same time slot, the number of configured authorized HARQ processes, the system frame number, the number of time slots in a frame, the number of symbols in a time slot, the time slot sequence number in the frame, the symbol sequence number in the time slot, and the index number of consecutive UL authorizations in the same configured authorization period.

[0192] In some embodiments, the uplink HARQ process ID is determined according to the number of consecutive time slots in the same configured authorization period in the uplink, the configured authorization period, the number of consecutive UL authorizations allocated in the same time slot, the number of HARQ processes configured for authorization, the system frame number, the number of time slots in a frame, the number of symbols in a time slot, the time slot sequence number in the frame, the symbol sequence number in the time slot, and the index number of consecutive UL authorizations in the same configured authorization period, including:

[0193] The current symbol of a multi-transport block is determined by the following formula:

[0194] Current symbol of multi-transport block = (system frame number × number of time slots in a frame × number of symbols in a time slot + time slot sequence number in a frame × number of symbols in a time slot + symbol sequence number in a time slot) + index number of consecutive UL grants in the same configured grant period * configured grant period / (number of consecutive time slots in the same configured grant period in the uplink * number of consecutive UL grants allocated in the same time slot);

[0195] The uplink HARQ process ID is determined by the following formula:

[0196] HARQ process ID = [floor (current symbol of multiple transport blocks / (configuration grant period / (number of consecutive time slots in the same configuration grant period in uplink * number of consecutive UL grants allocated in the same time slot))] modulo number of HARQ processes configured for grant;

[0197] The value range of the index number of the continuous UL grants in the same configured grant period is [0 to (the number of continuous time slots in the same configured grant period in the uplink * the number of continuous UL grants allocated in the same time slot - 1)].

[0198] Specifically, when the terminal device transmits data in the uplink, the calculation formula for calculating the HARQ process ID is:

[0199] HARQ Process ID=[floor(CURRENT_symbol_multi_TB / (periodicity / (cg-nroSlots*cg-nroPUSCH-InSlot))]modulo nrofHARQ-Processes

[0200] CURRENT_symbol_multi_TB=(SFN×numberOfSlotsPerFrame×numberOfSymbolsPerSlot+slot number in the frame×numberOfSymbolsPerSlot+symbol number in the slot)+UL_Grant_Index*periodicity / (cg-nroSlots*cg-nroPUSCH-InSlot)

[0201] Among them, CURRENT_symbol_multi_TB represents the current symbol of multiple transport blocks;

[0202] SFN means system frame number;

[0203] numberOfSlotsPerFrame indicates the number of time slots in a frame;

[0204] numberOfSymbolsPerSlot represents the number of symbols in a time slot;

[0205] slot number in the frame indicates the time slot sequence number in the frame;

[0206] numberOfSymbolsPerSlot represents the number of symbols in a time slot;

[0207] symbol number in the slot represents the symbol sequence number in the time slot;

[0208] UL_Grant_Index indicates the index number of consecutive UL grants in the same configuration grant period, and its value range is [0~(cg-nroSlots*cg-nroPUSCH-InSlot-1)];

[0209] Periodicity indicates the configuration authorization period;

[0210] cg-nroSlots indicates the number of consecutive time slots in the same configuration authorization period in the uplink;

[0211] cg-nroPUSCH-InSlot indicates the number of consecutive UL grants allocated in the same time slot;

[0212] HARQ Process ID indicates the HARQ process ID;

[0213] nrofHARQ-Processes indicates the number of HARQ processes authorized by the configuration.

[0214] For example, Figure 2 Take the example shown as an example, assuming that the current SCS is 15KHz, non-extended CP, and the configuration authorization period of CG is 10 time slots, that is:

[0215] numberOfSymbolsPerSlot=14

[0216] numberOfSlotsPerFrame = 10

[0217] SFN=1

[0218] slot number in the frame=1

[0219] symbol number in the slot=2

[0220] The number of HARQ processes reserved for the configuration grant is 12, the number of consecutive time slots is 4, and the number of consecutive UL grants in the same time slot is 2.

[0221] Based on the technical solution of this application, calculation Figure 2 The CURRENT_symbol_Multi_TB of uplink grant #0 and the corresponding HARQ process ID are:

[0222] CURRENT_symbol_Multi_TB=(SFN×numberOfSlotsPerFrame×numberOfSymbolsPerSlot+slot number in the frame×numberOfSymbolsPerSlot+symbol number in the slot)+UL_Grant_Index*periodicity / (cg-nroSlots*cg-nroPUSCH-InSlot)

[0223] =(1*10*14+1*14+2)+0*10*14 / 8=156

[0224] HARQ Process ID=[floor(CURRENT_symbol_multi_TB / (periodicity / (cg-nroSlots*cg-nroPUSCH-InSlot))]modulo nrofHARQ-Processes=[floor((156+0) / (10*14 / (4*2))]modulo 12=8

[0225] Calculate separately Figure 2 The CURRENT_symbol_Multi_TB and the corresponding HARQ process ID of uplink grant #1 are:

[0226] CURRENT_symbol_Multi_TB=(SFN×numberOfSlotsPerFrame×numberOfSymbolsPerSlot+slot number in the frame×numberOfSymbolsPerSlot+symbol number in the slot)+UL_Grant_Index*periodicity / (cg-nroSlots*cg-nroPUSCH-InSlot)

[0227] =(1*10*14+1*14+2)+1*10*14 / 8=156+17.5.

[0228] HARQ Process ID=[floor(CURRENT_symbol_multi_TB / (periodicity / (cg-nroSlots*cg-nroPUSCH-InSlot))]modulo nrofHARQ-Processes=[floor((156+17.5) / (10*14 / (4*2))]modulo 12=9

[0229] Figure 2 The calculation process of other uplink granted CURRENT_symbol_Multi_TB and the corresponding HARQ process ID is the same as the principle of the above calculation process, which will not be repeated here.

[0230] After calculation, we can get Figure 2 All CURRENT_symbol_Multi_TB and the corresponding HARQ process ID are shown in the following table:

[0231] CURRENT_symbol_Multi_TB HARQ Process ID 156 8 156+17.5 9 156+35 10 156+52.5 11 156+70 0 156+87.5 1 156+105 2 156+122.5 3

[0232] Based on the data in the above table, we can know that Figure 2 In the scheme shown, through the technical solution of the present application, the HARQ process IDs calculated for each transmission opportunity are different, so it can be achieved that the HARQ process IDs are different in the same CG cycle, avoiding the situation of HARQ process ID conflict, so that each HARQ process can be distinguished. Therefore, the terminal device and the network device can perform retransmission scheduling through different HARQ process IDs.

[0233] In some embodiments, the configuration parameters further include: multiple sets of configuration authorization parameters;

[0234] Correspondingly, the method also includes: the terminal device uses the sum of the determined uplink HARQ process ID and multiple sets of configured authorization parameters as the updated uplink HARQ process ID.

[0235] Specifically, the terminal device may also calculate the HARQ process ID by the following formula:

[0236] HARQ Process ID=[floor(CURRENT_symbol_multi_TB / (periodicity / (cg-nroSlots*cg-nroPUSCH-InSlot))]modulo nrofHARQ-Processes+harq-ProcID-Offset

[0237] Among them, harq-ProcID-Offset represents the authorization parameters in multiple configurations. It can be understood that if multiple configuration authorizations are not configured, this parameter can be omitted.

[0238] The following is an explanation of the process of determining the HARQ process ID during downlink transmission.

[0239] In some embodiments, when the HARQ process is a downlink transmission DL process, the number of consecutive time slots in the same cycle includes the number of consecutive time slots in the same half of the static scheduling SPS cycle in the downlink;

[0240] In addition, the configuration parameters also include: the number of consecutive time slots in a frame, the SPS period, and the number of HARQ processes of the SPS.

[0241] Correspondingly, the terminal device determines the downlink HARQ process ID based on the number of consecutive time slots in the same half of the static scheduling period in the downlink, including:

[0242] The terminal device determines the system frame number, the number of time slots in a frame, the time slot sequence number in the frame, and the index number of the semi-static scheduling in the same semi-static scheduling period;

[0243] The terminal device determines the HARQ process ID of the downlink based on the number of consecutive time slots in the same semi-static scheduling period in the downlink, the number of consecutive time slots in the frame, the semi-static scheduling period, the number of HARQ processes of the semi-static scheduling, the system frame number, the number of time slots in the frame, the time slot sequence number in the frame, and the index number of the semi-static scheduling in the same semi-static scheduling period.

[0244] In some embodiments, determining the downlink HARQ process ID according to the number of consecutive time slots in the same semi-static scheduling period in the downlink, the number of consecutive time slots in the frame, the semi-static scheduling period, the number of HARQ processes of the semi-static scheduling, the system frame number, the number of time slots in the frame, the time slot sequence number in the frame, and the index number of the semi-static scheduling in the same semi-static scheduling period includes:

[0245] The current time slot of the multi-transmission block is determined by the following formula:

[0246] Current time slot of multi-transport block = [(system frame number × number of time slots in a frame) + time slot sequence number in the frame + index number of SPS in the same SPS period * SPS period / number of consecutive time slots in the same half of the static scheduling period in the downlink]

[0247] The HARQ process ID is determined by the following formula:

[0248] HARQ process ID = [floor (current time slot of multiple transport blocks × 10 / (number of consecutive time slots in a frame × (SPS period / number of consecutive time slots in the same half of the static scheduling period in the downlink)))] modulo number of HARQ processes of SPS;

[0249] The range of the SPS index number in the same SPS period is [0 to the number of consecutive time slots in the same half of the static scheduling period in the downlink - 1].

[0250] Specifically, when the terminal device transmits data in the downlink, the calculation formula for calculating the HARQ process ID is:

[0251] HARQ Process ID=[floor(CURRENT_slot_Multi_TB×10 / (numberOfSlotsPerFrame×(periodicity / SPS-nroSlots)))]modulo nrofHARQ-Processes

[0252] CURRENT_slot_Multi_TB=[(SFN×numberOfSlotsPerFrame)+slot number in the frame+DL_grant_Index*periodicity / SPS-nroSlots],

[0253] Wherein, HARQ Process ID represents the HARQ process ID;

[0254] CURRENT_slot_Multi_TB indicates the current slot of multiple transport blocks;

[0255] numberOfSlotsPerFrame indicates the number of consecutive time slots in a frame;

[0256] periodicity indicates the SPS period;

[0257] SPS-nroSlots indicates the number of consecutive time slots in the same half of the static scheduling cycle in the downlink;

[0258] nrofHARQ-Processes indicates the number of HARQ processes of SPS;

[0259] SFN means system frame number;

[0260] numberOfSlotsPerFrame indicates the number of time slots in a frame;

[0261] slot number in the frame indicates the time slot sequence number in the frame;

[0262] DL_grant_Index indicates the index number of the SPS in the same SPS period.

[0263] Figure 5 FIG. 2 is another time domain schematic diagram of a multi-TB scenario in an embodiment of the present application. Figure 5 As shown, the number of consecutive SPS time slots is 2, and DL_grant_Index represents the sequence number of DL grants in the same SPS period, starting from 0, for example Figure 5 In the downlink scenario, the transmission opportunity corresponds to the downlink DL grant.

[0264] Figure 5 and Figure 2 as well as Figure 3 The difference is that Figure 2 as well as Figure 3 A schematic diagram showing an uplink scenario. Figure 5 This is a schematic diagram of a downlink scenario.

[0265] For example, Figure 5 Take the scenario shown as an example, assuming that the current SCS is 15KHz, non-extended CP, and the CG period is 10 time slots, that is:

[0266] numberOfSlotsPerFrame = 10

[0267] SFN=1

[0268] slot number in the frame=1

[0269] The number of HARQ processes reserved by SPS is 6, and the number of consecutive time slots is 2.

[0270] Based on the technical solution of this application:

[0271] (1) Targeting Figure 5 The CURRENT_symbol_Multi_TB and HARQ Process ID of SPS grant #0 are:

[0272] CURRENT_slot=[(SFN×numberOfSlotsPerFrame)+slot number in the frame+DL_grant_Index*periodicity / SPS-nroSlots]=[(1×10)+1+0*10 / 2]=10

[0273] HARQ Process ID=[floor(CURRENT_slot×10 / (numberOfSlotsPerFrame×(periodicity / SPS-nroSlots*)))]modulo nrofHARQ-Processes+harq-ProcID-Offset

[0274] =[floor(10×10 / (10×(10 / 2)))]modulo 6=2

[0275] (2) Targeting Figure 5 CURRENT_slot_Multi_TB and HARQ Process ID of SPS grant #1 are

[0276] CURRENT_slot=[(SFN×numberOfSlotsPerFrame)+slot number in the frame+DL_grant_Index*periodicity / SPS-nroSlots]=[(1×10)+1+1*10 / 2]=15

[0277] HARQ Process ID=[floor(CURRENT_slot×10 / (numberOfSlotsPerFrame×(periodicity / SPS-nroSlots*)))]modulo nrofHARQ-Processes+harq-ProcID-Offset

[0278] =[floor(15×10 / (10×(10 / 2)))]modulo 6=3

[0279] Based on the above calculation results, it can be known that for the specific scenario of downlink transmission, through the technical solution of the present application, it is possible to achieve different HARQ process IDs in the same SPS cycle, avoid HARQ process ID conflicts, and thus distinguish each HARQ process. Therefore, the terminal device and the network device can perform retransmission scheduling through different HARQ process IDs.

[0280] In some embodiments, the configuration parameters further include: multiple sets of SPS parameters;

[0281] Correspondingly, the method also includes: the terminal device uses the sum of the determined downlink HARQ process ID and multiple sets of SPS parameters as the updated downlink HARQ process ID.

[0282] Specifically, the terminal device may also calculate the HARQ process ID by the following formula:

[0283] HARQ Process ID=[floor(CURRENT_slot_Multi_TB×10 / (numberOfSlotsPerFrame×(periodicity / SPS-nroSlots)))]modulo nrofHARQ-Processes+harq-ProcID-Offset

[0284] Among them, harq-ProcID-Offset represents multiple sets of SPS parameters. It can be understood that if multiple sets of SPS are not configured, this parameter can be omitted.

[0285] It should be understood that, although the various steps in the flowcharts in the above-described embodiments are sequentially displayed according to the indications of the arrows, these steps are not necessarily executed sequentially in the order indicated by the arrows. Unless there is a clear description in this article, the execution of these steps is not strictly limited in order, and they can be executed in other orders. Moreover, at least a portion of the steps in the figure may include a plurality of sub-steps or a plurality of stages, and these sub-steps or stages are not necessarily executed at the same time, but can be executed at different times, and their execution order is not necessarily to be carried out sequentially, but can be executed in turn or alternately with other steps or at least a portion of the sub-steps or stages of other steps.

[0286] In some embodiments, based on the technical solutions of the aforementioned method embodiments, a terminal device is provided.
