[0030] To make the objectives, technical solutions, and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail with reference to the accompanying drawings.
[0031] URLLC related background
[0032] The requirements in URLLC support the transmission of services such as factory automation, transport industry, and electrical power distribution in the 5G system. To support the transmission of URLLC services, the CG is enhanced, that is, at least one CG configuration is introduced, and the specific configuration and use of CG resources (such as supporting the period of slot granularity, supporting the automatic transmission of CG, etc.) are enhanced.
[0033] CG Enhancement in URLLC
[0034] To support the high latency requirements of URLLC services, URLLC enhances the CG period and supports service periods at any slot level.
[0035] To support multiple URLLC services and the high latency requirements of URLLC services, URLLC introduces multiple types of CG (multiple CG). The Hybrid Automatic Repeat reQuest (HARQ) processes of different CG configurations are different, and the parameter harq-ProcID-Offset2 is configured to ensure that the processes of different CGs are different.
[0036] Due to the conflict between CG resources and other resources, in order to ensure that the Deprioritized Medium Access Control Protocol Data Unit (Deprioritized MAC PDU) that has been packetized in CG resources is not discarded / transmitted as soon as possible, automatic transmission for CG is introduced. For the CG of the packetized MAC PDU that cannot be transmitted due to resource conflict, the CG resources in the same CG configuration of the subsequent and the same HARQ process can be used for new transmission. The UE determines to use automatic transmission through the configuration parameter autonomousTx.
[0037] NR-U Related Background
[0038] The working group of the Third Generation Partnership Proiect (3GPP) agreed to initiate the project of NR unlicensed operation mode in December 2018. The goal of this project is to enable NR to operate in unlicensed frequency bands, including the following working scenarios:
[0039] Scenario A: Carrier Aggregation scenario, where the Primary Cell (PCell) is in licensed spectrum and aggregates Secondary Cells (SCells) operating in unlicensed spectrum through carrier aggregation;
[0040] Scenario B: Dual-Connectivity working scenario, where the PCell is in Long-Term Evolution (LTE) licensed spectrum and the Primary Secondary Cell (PScell) is in NR unlicensed spectrum;
[0041] Scenario C: Standalone working scenario, where NR operates as an independent cell in unlicensed spectrum;
[0042] Scenario D: NR single-cell scenario, where the UpLink (UL) operates in licensed spectrum and the DownLink (DL) operates in unlicensed spectrum;
[0043] Scenario E: Dual-Connectivity working scenario, where the PCell is in NR licensed spectrum and the PSceU is in NR unlicensed spectrum.
[0044] Generally speaking, the operating bands of NR-U are the 5 GHz unlicensed spectrum and the 6 GHz unlicensed spectrum. In the unlicensed spectrum, the design of NR-U should ensure fairness with other systems already operating in these unlicensed spectrums, such as WiFi. The principle of fairness is that the impact of NR-U on systems already deployed in the unlicensed spectrum (such as WiFi) should not exceed the impact between these systems.
[0045] To ensure fair coexistence among systems in the unlicensed spectrum, energy detection has been agreed as a basic coexistence mechanism. The general energy detection mechanism is the LBT mechanism. The basic principle of this mechanism is that before a base station or a terminal (transmission end) transmits data in the unlicensed spectrum, it needs to listen for a specified period of time according to the regulations. If the listening result indicates that the channel is idle, the transmission end can transmit data to the receiving end. If the listening result indicates that the channel is occupied, the transmission end needs to back off for a specified period of time and then continue to listen to the channel until the listening result of the channel is idle before it can transmit data to the receiving end.
[0046] Currently, four channel access mechanisms (categories) have been defined in NR-U:
[0047] Category 1: Direct Transmission mechanism:
[0048] This mechanism for the transmission side can transmit quickly after the switching gap within the Channel Occupancy Time (COT); where the Switching gap refers to the switching time for receiving transmission, and the typical value is no more than 16 us;
[0049] Category 2: LBT mechanism that does not require random back-off
[0050] This mechanism means that the time for the UE to listen to the channel is determined, generally relatively short, such as 25 us;
[0051] Category 3: LBT mechanism with random back-off (fixed contention window)
[0052] In the LBT process, the transmission side randomly selects a random value in the contention window to determine the time for listening to the channel;
[0053] Category 4: LBT mechanism with random back-off (variable contention window)
[0054] In the LBT process, the transmission side randomly selects a random value in the contention window to determine the time for listening to the channel, and the contention window is variable.
[0055] In summary, for the terminal, the base station needs to transmit data to the terminal within the maximum channel occupancy time (MCOT). If the base station fails to seize the channel, that is, outside the MCOT time, the terminal will not receive the scheduling data sent by the base station to this terminal.
[0056] Uplink LBT failure in NR-U
[0057] For the uplink transmission initiated by the UE, there are mainly the following categories:
[0058] SR (scheduling request): used to request uplink resources;
[0059] Physical Random Access Channel (PRACH) transmission: Due to RACH triggering, the UE needs to send msg1;
[0060] Physical Uplink Shared Channel (PUSCH) transmission: including uplink data transmission based on CG and uplink data transmission based on Dynamic Grant (DG);
[0061] Physical layer signaling transmission: including acknowledgment / negative acknowledgment (ACK / NACK) feedback, channel state information (CSI) reporting, etc.;
[0062] On the unlicensed frequency band, before the UE transmits SR, PRACH, or PUSCH, it needs to use LBT to listen to whether the channel is available. If the channel is not available, that is, the LBT fails, the UE needs to wait until the next transmission opportunity to perform LBT again. If LBT failure is detected, the physical layer needs to notify the MAC layer of the LBT failure information.
[0063] CG enhancement in NR-U
[0064] For flexible resource selection, the HARQ process of NR-U CG is not calculated according to a formula, but is selected by the UE itself. For a CG resource, the RRC configures a set of HARQ processes, and the UE can select a HARQ process from this set of HARQ processes for the current CG transmission. The specific configured HARQ process range is determined by the parameter harq-ProcID-Offset and the parameter nrofHARQ-Processes.
[0065] To support back-to-back resource configuration, NR-U introduces multiple types of CG (multiple CG). At least one CG configuration can share the HARQ process.
[0066] A CG retransmission timer (cg-RetransmissionTimer) is introduced to support the automatic retransmission of resources when the CG resources cannot be transmitted due to LBT failure. After the CG retransmission timer expires, if the CG timer (ConfiguredGrantTimer) has not expired, the corresponding HARQ process can be retransmitted.
[0067] CG transmission can be interrupted by dynamic scheduling downlink control information (DCI) and downlink feedback information (DFI). The specific behavior is shown in Table 1 below:

[0073] The network device 20 is a device deployed in the access network to provide wireless communication capabilities for the terminal device 10.

In systems using different radio access technologies, the name of the device with network device functions may be different. For example, in a 5G NR system, it is called a gNodeB or gNB. With the evolution of communication technologies, the name of the "network device" may change. For ease of description, in the embodiments of the present application, the device that provides wireless communication capabilities for the terminal device 10 is collectively referred to as a network device.
[0074] The "5G NR system" in the embodiments of the present disclosure may also be referred to as a 5G system or an NR system. This NR system may be a communication system that supports NR-U, but those skilled in the art can understand its meaning. The technical solutions described in the embodiments of the present disclosure may be applicable to a 5G NR system or subsequent evolved systems of the 5G NR system.
[0075] Figure 2 The figure shows a flowchart of a method for determining a HARQ process provided by an embodiment of the present application. Figure 2 Taking the method applied to Figure 1 the terminal shown as an example. The method includes:
[0076] Step 220: When the first type of CG and the second type of CG are configured simultaneously, the HARQ processes between the first type of CG and the second type of CG do not share, or at least one HARQ process is shared between the HARQ processes of the first type of CG and the second type of CG.
[0077] In one design, when the first type of CG and the second type of CG are configured simultaneously, the HARQ processes of the first type of CG and the second type of CG are not shared. Optionally, the network device restricts the non - sharing between the HARQ processes of the first type of CG and the second type of CG. Optionally, the terminal expects the non - sharing between the HARQ processes of the first type of CG and the second type of CG.
[0078] In one design, when the first type of CG and the second type of CG are configured simultaneously, at least one HARQ process is shared between the HARQ processes of the first type of CG and the second type of CG. Optionally, there is at least one HARQ process shared by the first type of CG and the second type of CG. Optionally, the first type of CG and the second type of CG share at least a part of the HARQ processes. Optionally, the network device allows the first type of CG and the second type of CG to share at least one HARQ process.
[0079] The first type of CG is a CG configuration for supporting high - reliability and low - latency services, or the first type of CG is a CG configuration for supporting uplink services on an authorized bandwidth or in an NR system, or the first type of CG is a CG configuration for supporting high - reliability and low - latency services on an authorized bandwidth or in an NR system; optionally, the first type of CG is a CG configuration or CG configuration method corresponding to Rel - 16. Among them, high - reliability and low - latency services include, but are not limited to, at least one of URLLC services, time - sensitive services, and V2X services.
[0080] The second type of CG is a CG configuration for supporting uplink services on an unlicensed bandwidth or in an NR - U system. Optionally, the second type of CG is a CG configuration or CG configuration method corresponding to Rel - 16.
[0081] In summary, the method provided in this embodiment reduces the complexity of the UE by not sharing the HARQ processes between the first type of CG and the second type of CG; by sharing at least one HARQ process between the first type of CG and the second type of CG, the utilization efficiency of the HARQ process can be improved, and the communication efficiency can be improved.
[0082] In an optional embodiment based on Figure 2 the above - mentioned method further includes at least one of the following two steps:
[0083] 1. Determine the HARQ process of the CG resource according to the first rule;
[0084] 2. Determine the transmission mode of the CG resource according to the second rule.
[0085] For determining the HARQ process of the CG resource according to the first rule, the following embodiments are provided.
[0086] Figure 3The flowchart of the HARQ determination method provided by an embodiment of the present application is shown. Figure 3 This method is applied to Figure 1 the communication system shown for illustration. The method includes:
[0087] Step 320: The network device simultaneously configures the first type of CG and the second type of CG for the terminal;
[0088] The first type of CG is the CG configuration when supporting high-reliability and low-latency services, or the first type of CG is the CG configuration when supporting uplink services on the authorized bandwidth or NR system, or the first type of CG is the CG configuration when supporting high-reliability and low-latency services on the authorized bandwidth or NR system; Optionally, the first type of CG is the CG configuration or CG configuration method corresponding to Rel-16. Among them, high-reliability and low-latency services include but are not limited to at least one of URLLC services, time-sensitive services, and V2X services.
[0089] The second type of CG is the CG configuration when supporting uplink services on the unlicensed bandwidth or NR-U system. Optionally, the second type of CG is the CG configuration or CG configuration method corresponding to Rel-16.
[0090] The first type of CG configuration corresponds to one or more first CG resources. The second type of CG configuration corresponds to one or more second CG resources.
[0091] Optionally, for one UE or one CG, the network device simultaneously configures the CG resources of the first type of CG and the CG resources of the second type of CG for the terminal; or, the network device simultaneously configures the CG parameters of the first type of CG and the CG parameters of the second type of CG for the terminal.
[0092] Optionally, for one UE or one CG, the network device only configures the CG resources of the first type of CG or the CG resources of the second type of CG for the terminal; or, the network device only configures the CG parameters of the first type of CG and the CG parameters of the second type of CG for the terminal.
[0093] Optionally, for one CG, the network device configures the corresponding HARQ process resources or HARQ process parameters for the terminal.
[0094] Optionally, the network device configures the corresponding HARQ process resources for the CG resources for the terminal.
[0095] Optionally, for one HARQ process, this HARQ process is not shared by the first type of CG and the second type of CG. Or, for one HARQ process, this HARQ process is only for the first type of CG or the second type of CG.
[0096] Optionally, for a HARQ process, the HARQ process is shared by a first type of CG and a second type of CG. Alternatively, the first type of CG and the second type of CG share at least part of the HARQ processes.
[0097] Optionally, the network device configures an indication for the terminal to indicate whether the HARQ processes are shared, or an indication for the terminal to indicate whether the HARQ processes are shared by URLLC and NRUCG. The indication is for each UE (per UE) or a single UE; or, the indication is for each CG (per CG) or a single CG; or, the indication is for each HARQ process (per HARQ process) or a single HARQ process; or, the indication is for each CG group (per CG group) or a single CG group; or, the indication is for each HARQ process group (per HARQ process group) or a single HARQ process group.
[0098] Optionally, for one CG resource, or multiple CG resources (a group), their HARQ processes can be shared. The CG resource or multiple CG resources can be NRUCG and / or URLLC CG.
[0099] For example, CG index 1 and CG index 2 correspond to the first type of CG, and the corresponding HARQ processes are process 1, process 2, and process 3. CG index 3 and CG index 4 correspond to the second type of CG, and the corresponding HARQ processes are process 1, process 4, and process 5. The first type of CG and the second type of CG share HARQ process 1.
[0100] For another example, CG index 5 and CG index 6 correspond to the first type of CG, and the corresponding HARQ processes are process 6 and process 7. CG index 7 and CG index 7 correspond to the second type of CG, and the corresponding HARQ processes are process 8 and process 9. The first type of CG and the second type of CG do not share HARQ processes.
[0101] The network device sends first CG configuration information to the terminal, and the first CG configuration information is used to configure the first type of CG and the second type of CG simultaneously, or to configure the configuration parameters of the first type of CG and the configuration parameters of the second type of CG simultaneously. Optionally, the first CG configuration information is a Radio Resource Control (RRC) message for CG configuration, also known as RRCCG configuration information.
[0102] Optionally, the network device configures an indication for the terminal to indicate whether different types of CGs are configured simultaneously, or an indication for the parameters of different types of CG configurations to indicate whether they can appear simultaneously. This indication is for each UE (per UE) or a single UE; or, this indication is for each CG (per CG) or a single CG; or, this indication is for each HARQ process (per HARQ process) or a single HARQ process; or, this indication is for each CG group (per CG group) or a single CG group; or, this indication is for each HARQ process group (per HARQ process group) or a single HARQ process group.
[0103] Optionally, the network device also configures a first rule for the terminal. The first rule is used to determine the HARQ process of the CG resource. The first rule can be carried in the first CG configuration information, or carried in the first indication information, or carried in other information, such as broadcast, Medium Access Control Control Element (MAC CE), Downlink Control Information (DCI), other dedicated RRC messages, etc. For example, the network device sends the first indication information to the terminal, and the first indication information is used to indicate that the HARQ process of the CG resource is determined by using the first HARQ process determination method and / or the second HARQ process determination method;
[0104] Among them, the first HARQ process determination method is the HARQ process determination method corresponding to the first type of CG, and the second HARQ process determination method is the HARQ process determination method corresponding to the second type of CG.
[0105] Step 340: When the terminal configures the first type of configured grant CG and the second type of CG simultaneously, the HARQ processes between the first type of CG and the second type of CG are not shared, or at least one HARQ process is shared between the HARQ processes of the first type of CG and the second type of CG;
[0106] Step 360: The terminal determines the HARQ process of the CG resource according to the first rule.
[0107] When determining the HARQ process of the CG resource according to the first rule, it includes but is not limited to using at least one of the following methods:
[0108] · Determine the HARQ process of the CG resource by using the first HARQ process determination method;
[0109] · Determine the HARQ process of the CG resource by using the second HARQ process determination method.
[0110] In a possible design, the terminal determines the HARQ process of the CG resource according to the first HARQ process determination method, where the first HARQ process determination method is the HARQ process determination method corresponding to the first type of CG; or, determines the HARQ process of the CG resource according to the second HARQ process determination method, where the second HARQ process determination method is the HARQ process determination method corresponding to the second type of CG.
[0111] For example, for the CG resource configured with the first type of CG, determine the HARQ process of the CG resource according to the HARQ process determination method of the NR system; or, determine the HARQ process of the CG resource according to the HARQ process determination method corresponding to the URLLC service transmission; or, determine the HARQ process of the CG resource according to the HARQ process calculation formula.
[0112] For example, for the CG resource configured with the second type of CG, determine the HARQ process of the CG resource according to the HARQ process determination method in the unlicensed bandwidth or NR-U system; or, determine the HARQ process of the CG resource according to the HARQ process determination method when the uplink service is supported in the unlicensed bandwidth or NR-U system; or, determine the HARQ process of the CG resource according to the method selected by the UE.
[0113] In a possible design, according to the predefined or default settings or the first indication information or the first CG configuration information, determine the HARQ process of the CG resource according to the first HARQ process determination method;
[0114] Or,
[0115] According to the predefined or default settings or the first indication information or the first CG configuration information, determine the HARQ process of the CG resource according to the second HARQ process determination method.
[0116] Optionally, as Figure 4 shown, the indication method of the first indication information includes but is not limited to at least one of the following:
[0117] 1. The network device sends a system broadcast, the terminal receives the system broadcast, and the system broadcast carries the first indication information;
[0118] The system broadcast includes a System Information Block (SIB). The network device sends a certain SIB, and the SIB carries the first indication information.
[0119] 2. The network device receives a dedicated signaling, and the dedicated signaling carries the first indication information;
[0120] The dedicated signaling is UE-dedicated signaling, such as RRC messages, MAC CE, or DCI. The network device sends the dedicated signaling, and the dedicated signaling carries first indication information.
[0121] 3. Receive second CG configuration information. Optionally, the second CG configuration information carries first indication information.
[0122] Optionally, the second CG configuration information is an RRC message.
[0123] Optionally, determine the HARQ process determination method according to the CG resource configuration parameters or configuration method in the second CG configuration information.
[0124] Optionally, the first indication information is configured for each terminal or a single terminal; or, the first indication information is configured for each CG or a single CG; or, the first indication information is configured for each CG group or a single CG group; or, the first indication information is configured for each HARQ process or a single CG.
[0125] For example, for CG index 1, the network device indicates to the UE the CG resources for CG index 1, and when the CG resources are transmitted, preferentially select the first HARQ process determination method to determine the corresponding HARQ process.
[0126] For another example, for CG index 3, the network device indicates to the UE the resources for CG index 3, and when the CG resources are transmitted, preferentially select the second HARQ process determination method to determine the corresponding HARQ process.
[0127] For another example, the UE receives the first CG configuration information from the network, configures the corresponding CG resources according to the first CG configuration information, and uses the corresponding CG resources for transmission. For an available CG resource:
[0128] If the network device configures only one type of CG for the UE, such as configuring the first type of CG, determine the HARQ process of the CG resources according to the first HARQ determination method; for another example, if the second type of CG is configured, determine the HARQ process according to the second HARQ determination method.
[0129] For another example, the UE receives the first CG configuration information from the network, configures the corresponding CG resources according to the first CG configuration information, and uses the corresponding CG resources for transmission. For an available CG resource, regardless of whether it is the first type of CG or the second type of CG, or regardless of whether the parameters of the first type of CG or the parameters of the second type of CG are configured, determine the HARQ process according to the second HARQ determination method.
[0130] For another example, the UE receives the first CG configuration information of the network, configures the corresponding CG resources according to the first CG configuration information, and uses the corresponding CG resources for transmission. For an available CG resource, regardless of whether it is a first-type CG or a second-type CG, or regardless of whether the parameters of the first-type CG or the second-type CG are configured, the HARQ process is determined according to the first HARQ determination method.
[0131] For another example, the UE receives the first CG configuration information of the network and determines the HARQ determination method according to whether it is connected to an NR or NR-U system. For example, if it is connected to an NR system, the HARQ process is determined according to the first HARQ determination method. For example, if it is connected to an NR-U system, the HARQ process is determined according to the second HARQ determination method.
[0132] If for this CG resource, (all) HARQ processes are not shared, or rather, (all) HARQ processes are not shared by the first-type CG and the second-type CG, the HARQ process is determined according to the following rules:
[0133] If the first condition is met, the first HARQ process determination method is used, that is, the HARQ process calculated according to the HARQ calculation formula. The first condition is at least one of the following:
[0134] 1. The CG resource is a first-type CG, abbreviated as the high-reliability and low-latency service CG;
[0135] 2. The configuration method of the CG resource is the configuration method of the first-type CG, that is, it includes at least one of the specific configuration parameters of the first-type CG, such as autonomous transmission (autonomousTX), the second HARQ process offset (harq-ProcID-Offset2), and the redundancy version of the retransmission (RepRV).
[0136] 3. At least one of the following configuration parameters is not configured for the CG resource: at least one of the CG retransmission timer (cg-RetransmissionTimer), the first HARQ process offset harq-ProcID-Offset, the COT-related parameter, the number of CGs configured per time slot (nrofCG-slot), and the number of PUSCHs configured per time slot (nrofPUSCH). These parameters are used to configure the CG transmission resources.
[0137] 4. At least the CG resource or the MAC entity corresponding to the CG resource is configured with a logical-channel-based prioritization determination method (lch-basedPrioritization). lch-basedPrioritization is used to select the resources for priority transmission.
[0138] If the second condition is satisfied, use the second HARQ process determination method, that is, the UE independently selects the HARQ process to be used in the configured HARQ resource pool. The second condition is at least one of the following:
[0139] 1. The CG resource is of the second type of CG;
[0140] 2. The configuration method of the CG resource is the configuration method of the second type of CG, that is, it includes specific configuration parameters configured by the second type of CG, such as at least one of the CG retransmission timer cg-RetransmissionTimer, harq-ProcID-Offset, COT-related parameters, nrofCG-slot, and nrofPUSCH.

[0142] 4. At least the second HARQ process offset (harq-ProcID-Offset2) is not configured for the CG resource;
[0143] 5. At least the autonomous transmission autonomousTX is not configured for the CG resource.
[0144] In a possible design, for one or a group of CG resources, the terminal preferentially uses the first HARQ process determination method to determine the first HARQ process; if the first HARQ process meets the first judgment condition, then use the second HARQ process determination method to determine the second HARQ process as the HARQ process of the CG resource.
[0145] Among them, the first HARQ process determination method is the HARQ process determination method corresponding to the first type of CG, and the second HARQ process determination method is the HARQ process determination method corresponding to the second type of CG.
[0146] Among them, the first judgment condition includes any one of the following conditions:
[0147] · The first HARQ process is a shared HARQ process;
[0148] · The first HARQ process is occupied;
[0149] · The CG timer is not started, but the CG retransmission timer is configured;
[0150] · The first HARQ process is occupied and the CG timer is not started;
[0151] · The first HARQ process is occupied and the carried Medium Access Control Protocol Data Unit (MAC PDU) is not of low priority;
[0152] · There is data that fails to be transmitted due to LBT failure;
[0153] · There is data that fails to be transmitted due to LBT failure and corresponds to the data shared by the CG process; the CG process is the HARQ process corresponding to the CG resource;
[0154] · The first HARQ process is not the HARQ process supported by the configuration. For example, the first HARQ process is process 4, but the HARQ process resources configured for this CG resource include processes 1 to 3, then the first HARQ process is not the HARQ process supported by the configuration.
[0155] In a possible design, for one or a group of CG resources, the terminal preferentially uses the first HARQ process determination method to determine the first HARQ process; if the first HARQ process meets the second determination condition, then use the first HARQ process as the HARQ process of the CG resource.
[0156] Among them, the second determination condition includes any one of the following conditions:
[0157] · The first HARQ process is not a shared HARQ process;
[0158] · The first HARQ process is not occupied;
[0159] · The CG timer is not started;
[0160] · The CG retransmission timer is not configured;
[0161] · The first HARQ process is occupied and the CG timer is not started;
[0162] · The first HARQ process is occupied and the carried MAC PDU is of low priority;
[0163] · There is no data that fails to be transmitted due to LBT failure;
[0164] · There is no data that fails to be transmitted due to LBT failure and corresponds to the data shared by the CG process.
[0165] In a possible design, for one or a group of CG resources, the terminal uses the second HARQ process determination method to determine the preferentially selected HARQ process; if the preferentially selected HARQ process meets the third determination condition, then use the first HARQ process determination method to determine the first HARQ process; determine the first HARQ process as the HARQ process of the CG resource.
[0166] Among them, the third judgment condition includes any one of the following conditions:
[0167] · There are multiple preferentially selected HARQ processes;
[0168] · There are multiple preferentially selected HARQ processes and include the first HARQ process;
[0169] Among them, the terminal determines the preferentially selected HARQ process by using the second HARQ process determination method; if there are multiple preferentially selected HARQ processes (multiple retransmissions to be transmitted, or multiple new transmissions to be transmitted), the first HARQ process is determined by using the first HARQ process determination method; if the preferentially selected HARQ process includes the first HARQ process, the first HARQ process is determined as the HARQ process of the CG resource.
[0170] · There are low-priority MAC PDUs in the first HARQ process;
[0171] · There is no data that fails to be transmitted due to LBT failure;
[0172] · There is no data corresponding to the CG process shared that fails to be transmitted due to LBT failure.
[0173] In a possible design, for one or a group of CG resources, the terminal determines the preferentially selected HARQ process by using the second HARQ process determination method; if there are multiple preferentially selected HARQ processes, the first HARQ process is determined by using the first HARQ process determination method; if the preferentially selected HARQ process does not include the first HARQ process, an HARQ process is selected by using the independent selection method and determined as the HARQ process of the CG resource.
[0174] In a possible design, for one or a group of CG resources, the terminal determines the preferentially selected HARQ process by using the second HARQ process determination method; if the preferentially selected HARQ process meets the fourth judgment condition, the preferentially selected HARQ process is determined as the HARQ process of the CG resource.
[0175] Among them, the fourth judgment condition includes any one of the following conditions:
[0176] · There is data that fails to be transmitted due to LBT failure;
[0177] · There is data corresponding to the CG process shared that fails to be transmitted due to LBT failure;
[0178] · There are no low-priority MAC PDUs.
[0179] In a possible design, when the terminal receives the downlink feedback information DFI and stops the CG retransmission timer or the CG retransmission timer times out, it preferentially selects the second HARQ process determined by the second HARQ process determination method, which is the HARQ process determined as the CG resource. The second HARQ process is also called the preferentially selected HARQ process.
[0180] Furthermore, if there are multiple HARQ processes that meet the preferentially selected condition (multiple retransmissions waiting to be transmitted, or multiple new transmissions waiting to be transmitted), the UE preferentially uses the HARQ process calculated according to the HARQ calculation formula; or, if there are multiple HARQ processes that meet the preferentially selected condition and among them there is a HARQ process calculated according to the HARQ calculation formula, the UE preferentially uses the HARQ process calculated according to the HARQ calculation formula; or, if there are multiple HARQ processes that meet the preferentially selected condition and among them there is no HARQ process calculated according to the HARQ calculation formula, the UE independently selects a HARQ process.
[0181] In a possible design, when the CG resource is a CG resource corresponding to the second type of CG, the terminal uses the second HARQ process determination method to determine the HARQ process of the CG resource; when the CG resource is a CG resource corresponding to the first type of CG, the terminal uses the first HARQ process determination method to determine the HARQ process of the CG resource.
[0182] In a possible design, when the CG resource is configured by the configuration parameters of the CG resource corresponding to the second type of CG, the terminal uses the second HARQ process determination method to determine the HARQ process of the CG resource; when the CG resource is configured by the configuration parameters of the CG resource corresponding to the first type of CG, the terminal uses the first HARQ process determination method to determine the HARQ process of the CG resource.
[0183] In a possible design, the second HARQ process determination method is used to determine the HARQ process of the CG resource. For example, in the case where the first type of CG and the second type of CG do not share the HARQ process, the second HARQ process determination method is always used to determine the HARQ process of the CG resource.
[0184] In a possible design, the second HARQ process determination method is used to determine the HARQ process of the CG resource. For example, in the NR-U system, regardless of the type of CG, or the CG configured according to the configuration parameters of which type of CG, the second HARQ process determination method is always used to determine the HARQ process of the CG resource.
[0185] It should be noted that the above first rule is configured for each terminal or a single terminal; or, the above first rule is configured for each CG or a single CG; or, the above first rule is configured for each CG group or a single CG group; or, the above first rule is configured for each HARQ process or a single HARQ process.
[0186] The following are some illustrative examples:
[0187] For an available CG resource with CG index 1, if the HARQ process 1 configured by the network device for it is shared, for any available CG resource, the UE preferentially determines the HARQ process according to the HARQ process calculation formula and uses this HARQ process for transmission. For any CG resource with CG index 1, or the HARQ process 1 (shared process) with CG index 1, exemplarily, if the CG timer is not running, it is transmitted as a new transmission; if the CG timer is running but the CG retransmission timer configuration is not running, it is transmitted as a retransmission.
[0188] For an available CG resource with CG index 1, if the HARQ process 1 configured by the network device for it is shared, for any available CG resource, the UE preferentially determines the HARQ process according to the HARQ process calculation formula. If the determined HARQ process is the non-shared HARQ processes 2 and 3, the transmission is performed according to the HARQ process determined by the HARQ process calculation formula. If the determined HARQ process is the shared HARQ process 1, then the HARQ process finally determined to be used among 1 / 4 / 5 is determined according to the NRU method. Or, if the HARQ process 1 is occupied and the MAC PDU carried in the occupied process is not of low priority, the UE then determines the HARQ process according to the NRU HARQ process calculation method.
[0189] For an available CG resource with CG index 1, if the HARQ process 1 configured by the network device for it is shared, for any available CG resource, the UE preferentially determines the HARQ process according to the HARQ process determination method corresponding to NRU.
[0190] For an available CG resource with CG index 1, if this CG resource is configured in the NRU system or frequency band, for any available CG resource, the UE preferentially determines the HARQ process according to the HARQ process determination method corresponding to NRU.
[0191] For an available CG resource with CG index 3, if the HARQ process 1 configured by the network device for it is shared, for any available CG resource, the UE preferentially determines the HARQ process according to the HARQ process determination method corresponding to the NR system.
[0192] If a HARQ process 1 configured by a network device for an available CG resource of CG index 3 is shared, for any available CG resource, the UE preferentially determines the HARQ process according to the HARQ process calculation formula. Regardless of whether the determined HARQ process is the HARQ process supported by this CG resource, the HARQ process determined by using the HARQ process formula is used for transmission.
[0193] If a HARQ process 1 configured by a network device for an available CG resource of CG index 3 is shared, for any available CG resource, the UE preferentially determines the HARQ process according to the HARQ process calculation formula. If the HARQ process determined according to the HARQ process formula is not the HARQ process supported by this CG, the UE then determines the HARQ process according to the HARQ process determination method corresponding to NRU.
[0194] In summary, the method provided in this embodiment gives a method for determining the HARQ process for CG resources in the case of simultaneously configuring the first type of CG and the second type of CG, ensuring consistent understanding between the network device and the terminal and clarifying the behavior of the terminal.
[0195] For the CG transmission mode of determining CG resources according to the second rule
[0196] Figure 5 The flowchart of the HARQ determination method provided by an embodiment of the present application is shown. Figure 5 Taking this method as being applied to Figure 1 the communication system shown for example. This method includes:
[0197] Step 520: The network device simultaneously configures the first type of CG and the second type of CG for the terminal;
[0198] The first type of CG is the CG configuration when supporting high-reliability and low-latency services, or the first type of CG is the CG configuration when supporting uplink services on an authorized bandwidth or NR system, or the first type of CG is the CG configuration when supporting high-reliability and low-latency services on an authorized bandwidth or NR system; optionally, the first type of CG is the CG configuration or CG configuration method corresponding to Rel-16. Among them, high-reliability and low-latency services include but are not limited to at least one of URLLC services, time-sensitive services, and V2X services.
[0199] The second type of CG is the CG configuration when supporting uplink services on an unlicensed bandwidth or NR-U system; optionally, the second type of CG is the CG configuration or CG configuration method corresponding to Rel-16.
[0200] The first type of CG configuration corresponds to one or more first CG resources. The second type of CG configuration corresponds to one or more second CG resources.
[0201] Optionally, for a UE or a CG, the network device configures the CG resources of the first type of CG and the CG resources of the second type of CG for the terminal simultaneously; or, the network device configures the CG parameters of the first type of CG and the CG parameters of the second type of CG for the terminal simultaneously.
[0202] Optionally, for a UE or a CG, the network device configures only the CG resources of the first type of CG or the CG resources of the second type of CG for the terminal; or, the network device configures only the CG parameters of the first type of CG and the CG parameters of the second type of CG for the terminal.
[0203] Optionally, for a CG, the network device configures the corresponding HARQ process resources, or HARQ process parameters, for the terminal.
[0204] Optionally, the network device configures the corresponding HARQ process resources for the CG resources for the terminal.
[0205] Optionally, for a HARQ process, the HARQ process is not shared by the first type of CG and the second type of CG. Or, for a HARQ process, the HARQ process is only for the first type of CG or the second type of CG.
[0206] Optionally, for a HARQ process, the HARQ process is shared by the first type of CG and the second type of CG. Or, the first type of CG and the second type of CG share at least some HARQ processes.
[0207] Optionally, the network device configures an indication for indicating whether the HARQ process is shared, or an indication for indicating whether the HARQ process is shared by URLLC and NRUCG for the terminal. The indication is for each UE (per UE) or a single UE; or, the indication is for each CG (per CG) or a single CG; or, the indication is for each HARQ process (per HARQ process) or a single HARQ process; or, the indication is for each CG group (per CG group) or a single CG group; or, the indication is for each HARQ process group (per HARQ process group) or a single HARQ process group.
[0208] Optionally, for a CG resource, or multiple CG resources (a group), their HARQ processes can be shared. The CG resource or multiple CG resources can be NRUCG and / or URLLC CG.
[0209] For example, CG index 1 and CG index 2 correspond to the first type of CG, and the corresponding HARQ processes are process 1, process 2, and process 5. CG index 5 and CG index 4 correspond to the second type of CG, and the corresponding HARQ processes are process 1, process 4, and process 5. The first type of CG and the second type of CG share HARQ process 1.
[0210] The network device sends third CG configuration information to the terminal. The third CG configuration information is used to configure the first type of CG and the second type of CG simultaneously, or to configure the configuration parameters of the first type of CG and the second type of CG simultaneously. Optionally, the third CG configuration information is an RRC message for CG configuration, also known as RRCCG configuration information.
[0211] Optionally, the network device configures an indication for the terminal to indicate whether different types of CGs are configured simultaneously, or an indication to indicate whether the parameters configured for different types of CGs can appear simultaneously. This indication is for each UE (per UE) or a single UE; or, this indication is for each CG (per CG) or a single CG; or, this indication is for each HARQ process (per HARQ process) or a single HARQ process; or, this indication is for each CG group (per CG group) or a single CG group; or, this indication is for each HARQ process group (per HARQ process group) or a single HARQ process group. Optionally, the network device also configures a second rule for the terminal. The second rule is used to determine the transmission mode of CG resources. The second rule can be carried in the third CG configuration information, or carried in the second indication information, or carried in other information, such as broadcast, MAC CE, DCI, other dedicated RRC messages, etc. For example, the network device sends the second indication information to the terminal, and the second indication information is used to indicate that the transmission mode of the first type of CG and / or the transmission mode of the second type of CG is determined as the transmission mode of CG resources.
[0212] Step 540: When the terminal configures the first type of configured grant CG and the second type of CG simultaneously, the HARQ processes between the first type of CG and the second type of CG are not shared, or at least one HARQ process is shared between the HARQ processes of the first type of CG and the second type of CG;
[0213] Step 560: The terminal determines the transmission mode of CG resources according to the second rule.
[0214] When determining the transmission mode of CG resources according to the second rule, it includes but is not limited to at least one of the following methods:
[0215] · Determine the transmission mode of CG resources by using the transmission mode of the first type of CG;
[0216] · Determine the transmission mode of the CG resource by using the transmission mode of the second type of CG.
[0217] In a possible design, the terminal determines the transmission mode of the CG resource according to the transmission mode of the first type of CG, and the transmission mode of the first type of CG is the transmission mode corresponding to the first type of CG; or, determines the transmission mode of the CG resource according to the transmission mode of the second type of CG, and the transmission mode of the second type of CG is the transmission mode corresponding to the second type of CG.
[0218] In a possible design, according to the predefined or default settings or the second indication information or the third CG configuration information, determine the transmission mode of the CG resource according to the transmission mode of the first type of CG;
[0219] Or,
[0220] According to the predefined or default settings or the second indication information or the third CG configuration information, determine the transmission mode of the CG resource according to the transmission mode of the second type of CG.
[0221] Optionally, as Figure 6 shown, the indication methods of the second indication information include but are not limited to at least one of the following:
[0222] 1. The network device sends a system broadcast, the terminal receives the system broadcast, and the system broadcast carries the second indication information;
[0223] The system broadcast includes a System Information Block (SIB). The network device sends a certain SIB, and the SIB carries the second indication information.
[0224] 2. The network device receives a dedicated signaling, and the dedicated signaling carries the second indication information;
[0225] The dedicated signaling is UE dedicated signaling, such as an RRC message, a MAC CE, or a DCI. The network device sends the dedicated signaling, and the dedicated signaling carries the second indication information.
[0226] 3. Receive the fourth CG configuration information. Optionally, the fourth CG configuration information carries the second indication information.
[0227] Optionally, the fourth CG configuration information is an RRC message.
[0228] Optionally, determine the CG resource transmission mode according to the CG resource configuration parameters or the configuration method in the first CG configuration information.
[0229] Optionally, when there is a HARQ process shared by the first type of CG and the second type of CG, the network device sends the second indication information to the UE to indicate the transmission mode of the CG resource.
[0230] When the second indication information indicates that the transmission mode of the CG resource is the transmission mode of the first type of CG, the CG transmission mode corresponding to high-reliability and low-latency is adopted, including at least one of the following: not carrying uplink control information (UCI) information, transmitting in a high-reliability and low-latency (such as URLLC) format, transmitting using the CG resource configured by the CG resource configuration method corresponding to high-reliability and low-latency (such as URLLC), and transmitting according to the specific configuration parameters of the first type of CG.
[0231] When the second indication information indicates that the transmission mode of the CG resource is the transmission mode of the second type of CG, the CG transmission mode corresponding to NRU is adopted, including at least one of the following: carrying UCI information, transmitting in the NRU format, transmitting using the CG resource configured by the CG resource configuration method corresponding to NRU, and transmitting according to the specific configuration parameters of the second type of CG.
[0232] Optionally, the second indication information is configured for each terminal or a single terminal; or, the second indication information is configured for each CG or a single CG; or, the second indication information is configured for each CG group or a single CG group; or, the second indication information is configured for each HARQ process or a single CG.
[0233] For example, for CG index 1, the network device indicates to the UE that for the CG resource of CG index 1, when transmitting the CG resource, the CG transmission mode corresponding to NRU is adopted. Then, for all CGs of CG index 1, when transmitting the CG, the NRU format is used for transmission, and UCI information is carried during transmission.
[0234] For example, for CG index 1, the network device indicates to the UE that for the CG resource corresponding to CG index 1 and HARQ process 1, when transmitting the CG resource, the CG transmission mode corresponding to NRU is adopted. Then, for the CGs selected in CG index 1 for HARQ process 1 to transmit the CG, the NRU format is used for transmission, and UCI information is carried. The remaining CG resources still adopt the CG transmission mode corresponding to URLLC.
[0235] For example, for CG index 3, the network device indicates to the UE that for the CG resource of CG index 3, when transmitting the CG resource, the CG transmission mode corresponding to NRU is adopted. Then, for all CGs of CG index 3, when transmitting the CG, the NRU format is used for transmission, and UCI information is carried during transmission.
[0236] When the network device does not send the second indication information to the terminal, the terminal determines the transmission mode of the CG resource according to a predefined method according to the transmission mode of the first type of CG or the second type of CG. The predefined method includes but is not limited to at least one of the following situations:
[0237] 1. If the network device configures only one type of CG for the UE, for example, configures the first type of CG, determine the transmission mode of the CG resource according to the transmission mode of the first type of CG; for another example, configures the second type of CG, determine the transmission mode of the CG resource according to the transmission mode of the second type of CG.
[0238] For example, if only one CG mode is configured for the UE, such as the second type of CG or the first type of CG, transmit according to the transmission mode of the second type of CG, or transmit according to the transmission mode of the first type of CG; or, if only one CG mode is configured for the UE, such as the second type of CG or the first type of CG, transmit according to the transmission mode of the second type of CG.
[0239] 2. If there are multiple CG configuration modes for the UE at the same time, such as the second type of CG and the first type of CG, transmit according to the transmission mode of the second type of CG. Or, if the CG resource is configured in the NRU system or frequency band, adopt the transmission mode of the second type of CG.
[0240] 3. If there are multiple CG configuration modes for the UE at the same time, such as the second type of CG and the first type of CG, transmit the second type of CG according to the transmission mode of the second type of CG, and transmit the first type of CG according to the transmission mode of the first type of CG. Optionally, determine the transmission mode of the CG resource according to the CG resource configuration parameter or configuration mode in the CG configuration information. Optionally, it is applicable to the scenario where all HARQ processes are not shared by the first type of CG and the second type of CG.
[0241] In a possible design, when there are multiple CG configuration modes for the UE at the same time: for this CG resource, if (all) HARQ processes are not shared, or in other words, (all) HARQ processes are not shared by URLLC CG and NRU CG, determine the transmission mode of the CG resource according to the following second rule.
[0242] When the fifth decision condition is met, determine the transmission mode of the second type of CG as the transmission mode of the CG resource;
[0243] Among them, the fifth decision condition includes at least one of the following conditions:

[0251] · The HARQ process of the CG resource is determined by the UE autonomous selection method;
[0252] · The HARQ process of the CG resource is not the HARQ process configured for the first type of CG.
[0253] Among them, the configuration method of the second type of CG includes:
[0254] · Containing specific configuration parameters of the NRU CG configuration, including but not limited to at least one of the following: CG retransmission timer, harq-ProcID-Offset, COT-related parameters, nrofCG-slot, nrofPUSCH.

[0263] · The configuration information of the second type of CG is not configured, or the CG resource is not configured according to the configuration method of the second type of CG;
[0264] · The CG resource is the first type of CG, or the CG resource is configured according to the configuration method of the first type of CG;
[0265] · Only the first type of CG is configured;
[0266] · The HARQ processes of the second type of CG and the first type of CG do not share HARQ processes.
[0267] Among them, the configuration method of the first type of CG includes:

[0269] · At least one of the following is not configured for the CG resource: CG retransmission timer, harq-ProcID-Offset, COT-related parameters, nrofCG-slot, nrofPUSCH.
[0270] · At least configure lch-basedPrioritization for the CG resource or the MAC entity corresponding to the CG resource.
[0271] In a possible design, when the CG resource is the CG resource corresponding to the second type of CG, the transmission method of the second type of CG is adopted; when the CG resource is the CG resource corresponding to the first type of CG, the transmission method of the first type of CG is adopted.
[0272] In a possible design, the transmission method of the second type of CG is adopted. For example, when the first type of CG and the second type of CG do not share HARQ processes, the transmission method of the second type of CG is always adopted.
[0273] In a possible design, if the CG resource is configured in the NR-U system or frequency point, the transmission method of the second type of CG is adopted.
[0274] It should be noted that the second rule is configured for each terminal or a single terminal; or, the second rule is configured for each CG or a single CG; or, the second rule is configured for each CG group or a single CG group; or, the second rule is configured for each HARQ process or a single HARQ process.
[0275] In one example, when there are multiple CG configuration methods for the UE simultaneously: when sharing the HARQ process of the CG resource, that is, when the HARQ process is shared by the URLLC CG and the NRU CG, the UE uses the second rule for the CG resource transmission method. (Scenario description: for a UE, the HARQ processes of some CG resources are not shared, and the HARQ processes of some CG resources are shared. This example applies to the latter) Specifically:
[0276] The second rule includes one of the following:
[0277] · When the UE uses the CG resource for transmission, it adopts the transmission method of the second type of CG.
[0278] · When the UE determines the HARQ process according to the NRU HARQ process selection method, it adopts the transmission method of the second type of CG.
[0279] · When the HARQ process selected by the UE is not the HARQ process calculated according to the HARQ calculation formula, it adopts the transmission method of the second type of CG.
[0280] · When the selected HARQ process is not the HARQ process configured for the first type of CG, it adopts the transmission method of the second type of CG;
