[0033] Next, the technical solutions in the embodiments of the present invention will be described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0034] First, a brief description will be given of the related technologies and some terms involved in the embodiments of the present invention, as follows:

[0035] 1. Background of Ultra-reliable and Low Latency Communications (URLLC) The 5G Radio Access Network (RAN) needs to support services such as factory automation, transport industry, and electrical power distribution in URLLC. To support the transmission of URLLC services, enhancements have been made to Configured Grant (CG), namely, multiple CG configurations have been introduced, and the specific configuration and use of CG (such as supporting slot-level periods and automatic transmission of CG) have been enhanced.

[0036] R17 needs to consider supporting URLLC services in the interference-controlled new generation (communication system) unlicensed (New Radio Unlicensed, NRU) scenario.

[0037] (1) It is possible to consider the usage mode of harmonizing NRU CG and ULRRC CG enhancements in the NRU scenario (Harmonizing UL configured-grant enhancements in NRU and URLLC introduced in Rel-16 to be applicable for unlicensed spectrum).

[0038] (2) It is possible to consider the UE-initial Channel Occupancy Time (UE-initial COT) for frame-based equipment. Here, FBE is Frame Based Equipment.

[0039] LBT defines two types of devices, one is FBE, and the other is LBE (Load Based Equipment). For FBE, a period is set, and channel detection is performed once at a fixed position in each period, such as performing CCA detection within each Clear Channel Assessment (CCA) detection time. If the channel state is detected as idle, the device can occupy the channel for transmission; if the channel state is detected as non-idle, the device cannot occupy the channel within this period until it waits until the fixed position in the next period to continue detection.

[0040] 2. CG Enhancements in URLLC

[0041] To support the high latency requirements of URLLC services, URLLC enhances the CG period and supports service periods at any slot-level.

[0042] To support multiple URLLC services and the high latency requirements of URLLC services, URLLC introduces multiple CGs. The Hybrid Automatic Repeat Request (HARQ) processes of different CG configurations are different, and the difference in processes of different CGs is ensured by the HARQ process identifier offset 2 (harq-ProcID-Offset2).

[0043] Due to conflicts between CG resources and other resources, to ensure that the Medium Access Control Protocol Data Unit (MAC PDU) (i.e., Deprioritized MAC PDU) that has been packetized in CG resources is not discarded / transmitted as soon as possible, autonomous transmission for CG is introduced. For the CG of the packetized MAC PDU that cannot be transmitted due to resource conflicts, the CG resources in the same CG configuration with the same HARQ process in the subsequent period can be used for new transmission. The autonomous transmission is determined through the autonomousTx mechanism.

[0044] If the physical layer priorities are different: there are conflicts between CGs, and the MAC can indicate one or more MAC PDUs to the physical layer. Similarly, if there are conflicts between data and the uplink Scheduling Request (SR), the MAC can also indicate the SR and MAC PDUs to the physical layer.

[0045] When low-priority resources appear, configure the Logical Channel (LCH)-based prioritization and the autonomousTx mechanism, and stop the CG retransmission timer (CGRT).

[0046] 3. Background related to NRU

[0047] NR operates in the unlicensed frequency band and can include the following working scenarios:

[0048] 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; Scenario B: Dual-connectivity working scenario, where the PCell is in Long Term Evolution (LTE) licensed spectrum and the PScell is in NR unlicensed spectrum; Scenario C: Standalone working scenario, where NR operates as an independent cell in unlicensed spectrum; Scenario D: NR single-cell scenario, where the uplink (UL) operates in licensed spectrum and the downlink (DL) operates in unlicensed spectrum; Scenario E: Dual-connectivity working scenario, where the PCell is in NR licensed spectrum and the PScell is in NR unlicensed spectrum.

[0049] Generally speaking, the operating bands of NRU are the 5 GHz unlicensed spectrum and the 6 GHz unlicensed spectrum. In the unlicensed spectrum, the design of NRU should ensure fairness with other systems that are already operating in these unlicensed spectrums, such as Wireless Fidelity (WiFi), etc. The principle of fairness is that the impact of NRU on systems already deployed in the unlicensed spectrum (such as WiFi) should not exceed the impact among these systems.

[0050] To ensure fair coexistence among systems in the unlicensed spectrum, energy detection has been agreed upon as a basic coexistence mechanism. The general energy detection mechanism is the Listen before talk (LBT) mechanism. The basic principle of this mechanism is that before a base station or a terminal (the transmitting 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 transmitting end can transmit data to the receiving end. If the listening result indicates that the channel is occupied, the transmitting 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.

[0051] Currently, four channel access mechanisms (categories) have been defined in NRU, referring to TR 38.889:

[0052] Category 1: Direct transmission mechanism;

[0053] This mechanism is used when the TX side can transmit quickly after the switching gap within the channel occupancy time (COT).

[0054] The switching gap refers to the conversion time for receiving a transmission, with a typical value of no more than 16 us;

[0055] Category 2: LBT mechanism that does not require random back-off;

[0056] This mechanism means that the time for the UE to listen to the channel is determined and generally short, such as 25 us;

[0057] Category 3: LBT mechanism with random back-off (fixed contention window);

[0058] In the LBT process, the transmitting side randomly selects a random value in the contention window to determine the time for listening to the channel;

[0059] Category 4: LBT mechanism with random back-off (variable contention window);

[0060] In the LBT process, the transmitting 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.

[0061] In summary, for the terminal device, the base station needs to transmit data to the terminal device within the maximum channel occupancy time (MCOT). If the base station fails to seize the channel, that is, outside the MCOT time, the terminal device will not receive the scheduling data from the base station for this terminal device.

[0062] 4. CG Enhancement in NR-U (also written as NRU in the following text)

[0063] For flexible resource selection, the HARQ process of NRU 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 one HARQ process from this set for the current CG transmission. The specific configured HARQ process range is determined by the HARQ process identifier offset (harq-ProcID-Offset) and the number of HARQ processes (nrofHARQ-Processes).

[0064] To support back-to-back resource configuration, NRU introduces multiple CG (multiple CG), where multiple CG configurations can share HARQ processes.

[0065] Furthermore, a CG retransmission timer (cg-RetransmissionTimer) is also introduced to support automatic retransmission when CG resources cannot be transmitted due to LBT failure. After the cg-RetransmissionTimer times out, if the CG timer (configuredGrantTimer, CGT) has not timed out, the corresponding HARQ process can perform retransmission.

[0066] CG transmission can be interrupted by dynamic scheduling downlink control information (Downlink Control Information, DCI) and (Downlink Feedback Information, DFI). The specific behavior is shown in Table 1 below:

[0067] Table 1

[0068]

[0069] Among them, the CG retx timer in Table 1 refers to the CG retransmission timer (CGRT).

[0070] If, based on the priority processing of the logical channel (Logical Channel, LCH) (LCH-based prioritization), when low-priority resources appear, the configuration stops the CG retransmission timer (CGRT).

[0071] 5. Uplink LBT Failure in NRU

[0072] For the uplink transmission initiated by the user equipment (User Equipment, UE), it mainly includes the following categories:

[0073] (1) Scheduling Request (SR): Used to request uplink resources;

[0074] (2) Physical Random Access Channel (PRACH) transmission: Triggered by the random access channel (Random Access Channel, RACH), the UE needs to send msg1;

[0075] (3) Physical Uplink Shared Channel (PUSCH) transmission: Includes uplink data transmission based on configured grant (CG) and uplink data transmission based on dynamic grant (DG);

[0076] (4) Physical layer signaling transmission: including Acknowledge (ACK) / Not Acknowledge (NACK) feedback, Channel Status Indicator (CSI) reporting, etc.;

[0077] On unlicensed spectrum, before the UE transmits SR, PRACH, or PUSCH, it needs to use LBT to listen to whether the channel is available. If it is not available, that is, LBT fails, the UE needs to wait for the next transmission opportunity to perform LBT again. If LBT failure is detected, the MAC layer needs to be notified of the LBT failure information.

[0078] When the network device indicates the configuration related to the Configured Grant (CG) resource for the terminal device, during the transmission of the CG resource, if a low-priority resource appears due to resource conflict, for different CG resource related configurations, how to handle the transmission of this low-priority resource, and the status of the corresponding CG timer, are currently undetermined. For example:

[0079] 1. In the case of simultaneously configuring LCH-based prioritization and CGRT, without configuring autonomousTX, when a resource conflict occurs and a low-priority resource appears, how to handle the low-priority resource, and / or, the status of the corresponding CG timer, is undetermined.

[0080] 2. In the case of simultaneously configuring autonomousTX and CGRT, when a resource conflict occurs and a low-priority resource appears, how to handle the low-priority resource, and / or, the status of the corresponding timer, is undetermined.

[0081] To solve the above problems, embodiments of the present invention provide a CG resource processing method, a terminal device, and a network device. The terminal device can receive the first configuration information sent by the network device; according to the first configuration information, determine the transmission mode of the configured grant CG resource, and / or, determine the status of the CG timer; wherein, the first configuration information is used to indicate at least one of the following: configure at least one CG resource; configure the CG timer CGT; configure the priority processing based on the logical channel LCH, or, not configure the priority processing based on the logical channel LCH; configure the CG retransmission timer CGRT, or, not configure CGRT; configure the automatic transmission mechanism, or, not configure the automatic transmission mechanism. In this way, according to the first configuration information configured by the network device, the terminal device can determine the transmission mode for the CG resource, and / or, the status of the CG timer, for different CG resource related configurations indicated by the network device.

[0082] Such as Figure 1As shown, it is the system architecture diagram of the communication system applied in the embodiments of the present invention. The communication system may include network devices, and the network devices may be devices that communicate with terminal devices (or referred to as communication terminals, terminals).

[0087] As an example rather than a limitation, in the embodiments of the present invention, the terminal device may also be a wearable device. A wearable device, also known as a wearable intelligent device, is a general term for devices developed by applying wearable technologies to the intelligent design of daily wear, such as glasses, gloves, watches, clothing, shoes, etc. A wearable device is a portable device that can be directly worn on the body or integrated into the user's clothes or accessories. A wearable device is not only a hardware device, but also realizes powerful functions through software support, data interaction and cloud interaction. Broadly speaking, wearable intelligent devices include those with complete functions and large sizes that can realize complete or partial functions without relying on a smart phone, such as smart watches or smart glasses, etc., and those that only focus on a certain type of application function and need to cooperate with other devices such as smart phones, such as various smart bracelets and smart jewelry for physical sign monitoring.

[0088] Among them, the network device may further include an access network device and a core network device. That is, the wireless communication system further includes a plurality of core networks for communicating with the access network device. The access network device may be an evolved base station (evolutional node B, which may be abbreviated as eNB or e-NodeB), a macro base station, a micro base station (also known as a "small base station"), a pico base station, an access point (AP), a transmission point (TP) or a new generation base station (gNodeB) in a long-term evolution (LTE) system, a next radio (NR) system or an authorized auxiliary access long-term evolution (LAA-LTE) system.

Here, the small cell may include: a metro cell, a micro cell, a pico cell, a femto cell, etc. These small cells have the characteristics of a small coverage area and a low transmission power, and are suitable for providing high-rate data transmission services.

[0092] It should be understood that in an embodiment of the present invention, a device with communication functions in a network / system may be referred to as a communication device. Taking Figure 1 the shown communication system as an example, the communication device may include a network device and a terminal device with communication functions. The network device and the terminal device may be specific devices in an embodiment of the present invention, which will not be elaborated here; the communication device may also include other devices in the communication system, such as other network entities like a network controller and a mobility management entity. This is not limited in an embodiment of the present invention.

[0093] The technical solution of the embodiment of the present invention can be applied to various communication systems, such as: Global System of Mobile communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, Advanced long term evolution (LTE-A) system, New Radio (NR) system, the evolved system of the NR system, LTE-based access to unlicensed spectrum (LTE-U) system, NR-based access to unlicensed spectrum (NR-U) system, Non-Terrestrial Networks (NTN) system, Universal Mobile Telecommunication System (UMTS), Wireless Local Area Networks (WLAN), Wireless Fidelity (WiFi), 5th-Generation (5G) system or other communication systems, etc.

[0094] Generally speaking, traditional communication systems support a limited number of connections and are easy to implement. However, with the development of communication technologies, mobile communication systems will not only support traditional communications, but also support, for example, Device to Device (D2D) communication, Machine to Machine (M2M) communication, Machine Type Communication (MTC), Vehicle to Vehicle (V2V) communication, or Vehicle to everything (V2X) communication, etc. The embodiment of the present invention can also be applied to these communication systems.

[0096] It should be understood that the "indication" mentioned in the embodiments of the present application can be a direct indication, an indirect indication, or a representation of an associated relationship. For example, A indicates B, which can mean that A directly indicates B. For example, B can be obtained through A; it can also mean that A indirectly indicates B. For example, A indicates C, and B can be obtained through C; it can also mean that there is an associated relationship between A and B.

Specifically, it can be a Configured grant config, and / or a MAC-CellGroupConfig.

[0100] As Figure 2 shown, the embodiments of the present invention provide a method for processing CG resources, including:

[0101] 201. The network device sends first configuration information to the terminal device.

[0102] Among them, the first configuration information is used to indicate at least one of the following:

[0108] 202. The terminal device determines the configuration grant CG resource transmission mode and / or determines the CG timer CGT status according to the first configuration information.

[0109] Optionally, if the first CG resource is a low-priority resource, determine the CG resource transmission mode and / or determine the CGT status according to the first configuration information.

[0110] Wherein, the first CG resource is one of at least one CG resource.

[0111] Optionally, the first CG resource being a low-priority resource may include the following situations:

[0112] Situation 1: The first CG resource is determined to be a low-priority CG resource due to priority processing based on LCH;

[0113] Situation 2: The first CG resource is determined to be a low-priority CG resource due to cancellation of the indication of the radio network temporary identity value CI-RNTI;

[0114] Situation 3: The first CG resource is determined to be a low-priority CG due to a conflict between the first CG resource and a high-priority physical uplink control channel PUCCH resource;

[0116] Situation 5: The first CG resource is determined to be a low-priority CG resource due to physical layer priority indication of the first CG resource.

[0117] In the embodiments of the present invention, for different implementation manners of the first configuration information, the implementation manners of determining the configuration grant CG resource transmission mode and / or determining the CGT status are also different. The following will separately describe several possible implementation manners:

If the first CG resource is a low-priority resource, NRU automatic retransmission is performed for the first CG resource through the second CG resource, and the existing low-priority MAC PDUs are retransmitted through other CG resources.

[0173] Optionally, if the first HARQ process is in a non-pending state and the first HARQ process is the HARQ process associated with the first CG resource and the second CG resource, then if the first CG resource is a low-priority resource, the CG resource transmission mode is determined according to the first configuration information, specifically, it can be several of the following in (A) to (H) above:

If the first CG resource is a low-priority resource, then for the first CG resource, NRU automatic retransmission is performed through the second CG resource, and the existing low-priority MAC PDUs are retransmitted through other CG resources.

[0182] In another alternative implementation: If the first CG resource is a low-priority resource, then according to the first configuration information, the CG resource transmission method is determined, including but not limited to any one of the following 1) to 11):

[0183] 1) If the first CG resource is a low-priority resource and CGT is stopped, then for the new MAC PDU packets of the first CG resource group, the new MAC PDU packets are newly transmitted through the second CG resource;

[0184] In the embodiments of the present invention, the time domain position of the second CG resource involved is after the first CG resource, and the second CG resource is associated with the same first HARQ process as the first CG resource. Alternatively, the time domain position of the second CG resource involved is after the first CG resource, and the data / MAC PDU of the first HARQ process associated with the first CG resource can be transmitted through the second CG resource or the second HARQ process corresponding to the second resource.

[0185] Optionally, determining CGT and the CG resource transmission method can be: If the first CG resource is a low-priority resource, then CGT is stopped, and for the new MAC PDU packets of the first CG resource group, the new MAC PDU packets are newly transmitted through the second CG resource; wherein, the time domain position of the second CG resource is after the first CG resource, and the second CG resource is associated with the same first HARQ process as the first CG resource.

[0186] Optionally, in the new transmission involved in the embodiments of the present invention, the new MAC PDU packets in the group can refer to either new data packetization (i.e., different from the data in the original low-priority MAC PDU packet) or a reorganized packet of the low-priority MAC PDU. It should be noted that this new transmission method applies to all interpretations of new MAC PDU packets involved in this article and will not be elaborated further.

[0187] It should be noted that in the embodiments of the present invention, the order between determining that the first CG resource is a low-priority resource and the CGT state is not limited, that is, it is possible to first determine that the first CG resource is a low-priority resource and then determine the CGT state (stop CGT or not stop), or it is possible to first determine the CGT state and then determine that the first CG resource is a low-priority resource.

[0188] It should be noted that in the embodiments of the present invention, the sequence between determining the CG resource transmission mode (such as the second CG resource transmission mode) and the CGT state may not be limited. That is, the CG resource transmission mode can be determined first, and then the CGT state (stop CGT or not stop CGT) can be determined, or the CGT state can be determined first, and then the CG resource transmission mode can be determined. Optionally, for the former, the CG resource transmission mode may be independent of the CGT state. Optionally, for the latter, the CG resource transmission mode may be related to the CGT state.

[0189] It should be noted that in the embodiments of the present invention, the CGRT state (which may include stopping CGRT or not stopping CGRT) can also be determined according to the first configuration information. And in the embodiments of the present invention, the sequence between determining the CG resource transmission mode, the CGT state, and the CGRT state is not limited either, that is, the sequence among the three can be set arbitrarily.

[0190] 2) If the first CG resource belongs to the first CG resource group, and the first CG resource is a low-priority resource and CGT is stopped, then a new MAC PDU packet is assembled, and the new MAC PDU packet is newly transmitted through the second CG resource;

[0192] 3) If the first CG resource belongs to the first CG resource group, and the first CG resource is a low-priority resource and CGT is stopped, then a new MAC PDU packet is assembled, the new MAC PDU packet is newly transmitted through the second CG resource, and the existing low-priority MAC PDUs are retransmitted through other CG resources; where the other CG resources are the resources in the first CG resource group except the first CG resource;

[0193] Optionally, determining the CGT and the CG resource transmission mode can be: if the first CG resource belongs to the first CG resource group and the first CG resource is a low-priority resource, then CGT is stopped, a new MAC PDU packet is assembled, the new MAC PDU packet is newly transmitted through the second CG resource, and the existing low-priority MAC PDUs are retransmitted through other CG resources; where the other CG resources are the resources in the first CG resource group except the first CG resource.

[0194] In the embodiments of the present invention, the other CG resources involved are the resources in the first CG resource group except the first CG resource.

[0195] Optionally, another possible scenario is as follows: The first CG resource belongs to the first CG resource group. If the first CG resource is a low-priority resource, a new MAC PDU packet is assembled and newly transmitted through the second CG resource, and other CG resources do not transmit.

[0196] Optionally, another possible scenario is as follows: The first CG resource belongs to the first CG resource group. If the first CG resource is a low-priority resource, a new MAC PDU packet is assembled and newly transmitted through the second CG Bundle.

[0197] Among them, the time domain position of the second CG Bundle is after the first CG bundle, and the HARQ process associated with the second CG bundle is the same as that of the first CG bundle, or the data / MAC PDU of the first HARQ process associated with the first CG bundle can be transmitted through the second HARQ process corresponding to the second CG bundle.

[0198] 4) If the first CG resource is a low-priority resource, satisfies the first condition, and does not stop CGT, then new transmission is performed through the second CG resource; the first condition includes but is not limited to: obtaining the MAC PDU, and at least one of no corresponding PUSCH being completely transmitted.

[0199] Optionally, determining the CGT and the CG resource transmission method can be: If the first CG resource is a low-priority resource and satisfies the first condition, then do not stop CGT, and perform new transmission through the second CG resource; the first condition includes but is not limited to: obtaining the MAC PDU, at least one corresponding PUSCH not being completely transmitted, and at least one of no corresponding PUSCH being completely transmitted. It should be noted that in the embodiments of the present invention, the order of determining that the first CG resource is a low-priority resource, the CGT state (stop CGT or not stop CGT), and satisfying the first condition is not limited, that is, the order among the three can be set arbitrarily.

[0200] It should be noted that in the embodiments of the present invention, the order of determining the second CG resource transmission method, the CGT state (stop CGT or not stop CGT), and satisfying the first condition can also be not limited, that is, the order among the three can be set arbitrarily.

[0201] 5) If the first CG resource is a low-priority resource, satisfies the first condition, and does not stop CGT, then new transmission is performed through the second CG resource; the new transmission is an IIoT / URLLC automatic transmission.

[0202] Optionally, the method for determining the CGT and CG resource transmission mode may be: if the first CG resource is a low-priority resource and the first condition is met, the CGT is not stopped, and new transmission is performed through the second CG resource; the new transmission is an IIoT / URLLC automatic transmission.

[0203] 6) If the first CG resource is a low-priority resource and the CGT is stopped, then NRU automatic retransmission is performed through the second CG resource;

[0204] Optionally, the method for determining the CGT and CG resource transmission mode may be: if the first CG resource is a low-priority resource, the CGT is stopped, and NRU automatic retransmission is performed through the second CG resource.

[0205] 7) If the first CG resource is a low-priority resource and the CGT is not stopped, then NRU automatic retransmission is performed through the second CG resource;

[0206] Optionally, the method for determining the CGT and CG resource transmission mode may be: if the first CG resource is a low-priority resource, the CGT is not stopped, and NRU automatic retransmission is performed through the second CG resource.

[0207] 8) The first CG resource belongs to the first CG resource group. If the first CG resource is a low-priority resource and the CGT is stopped, then for the first CG resource, NRU automatic retransmission is performed through the second CG resource;

[0208] Optionally, the method for determining the CGT and CG resource transmission mode may be: the first CG resource belongs to the first CG resource group. If the first CG resource is a low-priority resource, the CGT is stopped, and for the first CG resource, NRU automatic retransmission is performed through the second CG resource.

[0209] 9) The first CG resource belongs to the first CG resource group. If the first CG resource is a low-priority resource and the CGT is stopped, then for the first CG resource, NRU automatic retransmission is performed through the second CG resource, and the existing low-priority MAC PDUs are retransmitted through other CG resources;

[0210] Optionally, the method for determining the CGT and CG resource transmission mode may be: the first CG resource belongs to the first CG resource group. If the first CG resource is a low-priority resource, the CGT is stopped, and for the first CG resource, NRU automatic retransmission is performed through the second CG resource, and the existing low-priority MAC PDUs are retransmitted through other CG resources.

[0211] 10) The first CG resource belongs to the first CG resource group. If the first CG resource is a low-priority resource and the CGT is not stopped, then for the first CG resource, NRU automatic retransmission is performed through the second CG resource;

[0212] Optionally, the determined CGT and CG resource transmission methods can be as follows: The first CG resource belongs to the first CG resource group. If the first CG resource is a low-priority resource, CGT is not stopped, and for the first CG resource, NRU automatic retransmission is performed through the second CG resource.

[0213] 11) The first CG resource belongs to the first CG resource group. If the first CG resource is a low-priority resource and CGT is not stopped, then for the first CG resource, NRU automatic retransmission is performed through the second CG resource, and existing low-priority MAC PDUs are retransmitted through other CG resources.

[0214] Optionally, the determined CGT and CG resource transmission methods can be as follows: The first CG resource belongs to the first CG resource group. If the first CG resource is a low-priority resource, CGT is not stopped, and for the first CG resource, NRU automatic retransmission is performed through the second CG resource, and existing low-priority MAC PDUs are retransmitted through other CG resources.

[0215] Optionally, any one of the above (1) to (5), any one of the above (A) to (H), or any one of the above 1) to 11) can be determined in the case of new transmission through the first CG resource.

[0216] Optionally, for the case of retransmission through the first CG resource, any one of the above CGT states (1) to (5) can be determined.

[0217] Optionally, for the case of retransmission through the first CG resource, the following several of the above (A) to (H) can also be determined:

[0218] (A) If the first CG resource is a low-priority resource, a new MAC PDU packet is formed, and the new MAC PDU packet is newly transmitted through the second CG resource;

[0219] (D) If the first CG resource is a low-priority resource and the first condition is met, new transmission is performed through the second CG resource;

[0220] (E) If the first CG resource is a low-priority resource and the first condition is met, new transmission is performed through the second CG resource, and the new transmission is IIoT / URLLC automatic transmission;

[0221] (F) If the first CG resource is a low-priority resource, NRU automatic retransmission is performed through the second CG resource;

[0222] (G) The first CG resource belongs to the first CG resource group. If the first CG resource is a low-priority resource, then for the first CG resource, NRU automatic retransmission is performed through the second CG resource;

[0223] (H) The first CG resource belongs to the first CG resource group. If the first CG resource is a low-priority resource, for the first CG resource, NRU automatic retransmission is performed through the second CG resource, and the existing low-priority MAC PDUs are retransmitted through other CG resources.

[0224] Optionally, for the case of retransmission through the first CG resource, it is also possible to determine item 1) in the above 1) to 11), or any one of items 4) to 11).

[0225] The specific implementation process for the above Embodiment 1 is as follows:

[0226] Step 1: The gNB (i.e., the network device) allocates CG resources to the UE (i.e., the terminal device). When configuring the CG resources, the following parameters can be included:

[0227] Configure CGT;

[0228] Configure LCH-based prioritization;

[0229] Configure CGRT;

[0230] Do not configure autonomousTX.

[0231] Step 2: The UE uses the resources allocated by the network for transmission and determines the timer status. Specifically, when the CG resource is a low-priority resource (such as a resource considered low-priority due to a conflict, and at this time, there is a valid MAC PDU for packetizing the CG resource group), the UE processes according to the following table:

[0232] For example, during new transmission, if there is a CG resource that is low-priority due to LCH-based prioritization, or there is a CG resource that is low-priority due to CI-RNTI, or there is a CG resource that is low-priority due to a conflict with a high-priority PUCCH resource, the CGT corresponding to the CG resource is stopped. Correspondingly, for the next available CG resource, new packets are grouped for new transmission, or NRU automatic transmission is performed.

[0233] For example, during retransmission, if there is a CG resource that is low-priority due to LCH-based prioritization, or there is a CG resource that is low-priority due to CI-RNTI, or there is a CG resource that is low-priority due to a conflict with a high-priority PUCCH resource, the CGT corresponding to the CG resource does not stop (the status remains unchanged). Correspondingly, for the next available CG resource (in the case of CGT timeout), NRU automatic transmission is performed.

[0234] For example, during retransmission, if there is a CG resource with low priority due to LCH-based prioritization, or a CG resource with low priority due to CI-RNTI, or a CG resource with low priority due to conflict with a high-priority PUCCH resource, the CGT corresponding to the CG resource stops. Correspondingly, for the next available CG resource (in case of CGT timeout), the MAC PDU of the low-priority CG resource is discarded and new transmission packetization is performed.

[0235] For example, during retransmission, if there is a CG resource with low priority due to LCH-based prioritization, or a CG resource with low priority due to CI-RNTI, or a CG resource with low priority due to conflict with a high-priority PUCCH resource, the CGT corresponding to the CG resource stops. Correspondingly, for the next available CG resource (in case of CGT timeout), retransmission is performed, or automatic transmission is performed in a manner similar to the IIoT automatic transmission mode (assuming that at least one corresponding PUSCH is considered to have completed transmission).

[0236] In the embodiments of the present invention, a conflict refers to a resource conflict. Optionally, specifically, it may refer to a time-domain resource conflict, or a time-frequency domain resource conflict.

[0237] As a possible implementation manner, the timer state in the table can be determined according to the low-priority CG resource and / or the HARQ process state. The resource transmission mode can be determined according to at least one of the low-priority CG resource, the HARQ process state, and the timer state. The resource transmission mode can also be determined by other means, and the embodiments of the present invention do not make limitations.

[0238] Table 2

[0239]

[0240]

[0241] As shown in Table 2 above, the conditions configured by the network device are:

[0242] Configure LCH-based prioritization;

[0243] Configure CGRT;

[0244] Do not configure autonomousTX;

[0245] The CG resource is a low-priority resource (such as a resource considered to be low-priority due to conflict). In the above cases, the following implementation manners may be included but are not limited to:

[0246] One possible implementation is as follows: The currently used CG resource (i.e., the first CG resource) performs a new transmission (using the CG resource). When the HARQ process is in the pending state, retransmission is performed for the subsequent CG or CG bundle (i.e., the second CG resource or the second CG bundle), and automatic retransmission is carried out according to NRU. (If the CG is a bundle, for the other time domain, time-frequency domain positions, or repetitions in the bundle except for this new transmission, it is still processed according to the current bundle, that is, the existing and low-priority MAC PDUs are transmitted.)

[0247] Optionally, CGT is stopped at this time, and / or LBT can succeed or fail at this time.

[0248] One possible implementation is as follows: The currently used CG resource (i.e., the first CG resource) performs a new transmission (using the CG resource). When the HARQ process is in the pending state, retransmission is performed for the subsequent CG or CG bundle (i.e., the second CG resource or the second CG bundle), and automatic retransmission is carried out according to NRU. (If the CG is a bundle, for the other repetitions in the bundle except for this new transmission, it is still processed according to the current bundle, that is, the existing and low-priority MAC PDUs are transmitted.)

[0249] Optionally, CGT is not stopped at this time, and / or LBT can succeed or fail at this time.

[0250] One possible implementation is as follows: The currently used CG resource (i.e., the first CG resource) performs a new transmission (using the CG resource). When the HARQ process is not in the pending state, a new transmission is performed for the subsequent CG or CG bundle (i.e., the second CG resource or the second CG bundle), and a new MAC PDU packet is formed. (If the CG is a bundle, for the other repetitions in the bundle except for this new transmission, it is still processed according to the current bundle, that is, the existing and low-priority MAC PDUs are transmitted.)

[0251] Optionally, CGT is not stopped at this time, and / or LBT can succeed or fail at this time.

[0252] One possible implementation is as follows: The currently used CG resource (i.e., the first CG resource) performs a new transmission (using the CG resource). When the HARQ process is in the not pending state, retransmission is performed for the subsequent CG or CG bundle (i.e., the second CG resource or the second CG bundle), and automatic retransmission is carried out according to NRU. (If the CG is a bundle, for the other repetitions in the bundle except this new transmission, it is still processed according to the current bundle, that is, transmit the existing and low-priority MAC PDUs).

[0253] One possible implementation is as follows: The currently used CG resource (i.e., the first CG resource) performs retransmission (using the CG resource, for example, due to LBT failure, not receiving DFI-ACK, etc.; for example, retransmission in a bundle; for the current CG resource (such as this low-priority resource), CGT is already running). And the HARQ process is in the not pending state. (If the CG is a bundle, for the other retransmitted repetitions, retransmission is processed according to the existing bundle, that is, for the other repetitions in the bundle except this retransmission, it is still processed according to the current bundle, that is, transmit the existing and low-priority MAC PDUs). Retransmission is performed for the subsequent CG or CG bundle (i.e., the second CG resource or the second CG bundle), and automatic retransmission is carried out according to NRU.

[0254] Optionally, CGT is not stopped at this time, and / or LBT can succeed or fail at this time.

[0255] In the above Table 2, for the configuration in Embodiment 1, the method of transmitting low-priority resources and the processing method of the CG timer are given.

[0256] The specific implementation process for the above Embodiment 2 is as follows:

[0257] The specific implementation process is as follows:

[0258] The gNB (i.e., the network device) allocates CG resources to the UE (i.e., the retransmission device). When configuring the CG resources, the following parameters can be included:

[0259] Configure CGT;

[0260] Configure LCH-based prioritization;

[0261] Configure CGRT;

[0262] Configure autonomousTX.

[0263] In the above cases, the following implementation methods can be included but are not limited to:

[0264] The UE determines the transmission mode for CG resource transmission and determines the CG timer status using network-allocated parameters. Specifically, when the CG resource is a low-priority resource (such as a resource considered low-priority due to a conflict, and at this time, a valid MAC PDU of the CG packet is formed), the UE processes it according to the following table:

[0265] For example, during a new transmission, if there is a CG resource that is low-priority due to LCH-based prioritization, or there is a CG resource that is low-priority due to CI-RNTI, or there is a CG resource that is low-priority due to a conflict with a high-priority PUCCH resource, the corresponding CGT is stopped. Correspondingly, for the next available CG resource, it is transmitted automatically according to IIoT or NRU.

[0266] For example, during a retransmission, if there is a CG resource that is low-priority due to LCH-based prioritization, or there is a CG resource that is low-priority due to CI-RNTI, or there is a CG resource that is low-priority due to a conflict with a high-priority PUCCH resource, the corresponding CGT does not stop (the status remains unchanged). Correspondingly, for the next available CG resource (in the case of CGT timeout), it is transmitted automatically according to NRU.

[0267] For example, during a retransmission, if there is a CG resource that is low-priority due to LCH-based prioritization, or there is a CG resource that is low-priority due to CI-RNTI, or there is a CG resource that is low-priority due to a conflict with a high-priority PUCCH resource, the corresponding CGT is stopped. Correspondingly, for the next available CG resource (in the case of CGT timeout), the MAC PDU of the low-priority CG resource is discarded and a new transmission packet is formed.

[0268] For example, during a retransmission, if there is a CG resource that is low-priority due to LCH-based prioritization, or there is a CG resource that is low-priority due to CI-RNTI, or there is a CG resource that is low-priority due to a conflict with a high-priority PUCCH resource, the corresponding CGT is stopped. Correspondingly, for the next available CG resource (in the case of CGT timeout), a retransmission is performed, or it is transmitted automatically according to a similar IIoT automatic transmission method (assuming that at least one corresponding PUSCH has completed transmission).

[0269] As a possible implementation, the timer status in the table can be determined according to the low-priority CG resources and / or the HARQ process status. The resource transmission mode can be determined according to at least one of the low-priority CG resources, the HARQ process status, and the timer status. The resource transmission mode can also be determined by other means, which is not limited in the embodiments of the present invention.

[0274] Configure LCH-based prioritization;

[0275] Configure CGRT;

[0276] Configure autonomousTX;

[0277] When the CG resources are low-priority resources (such as resources considered low-priority due to conflicts), the following implementation manners can be included but are not limited to:

[0278] A possible implementation manner is: the currently used CG resource (i.e., the first CG resource) performs a new transmission (using the CG resource). When the HARQ process is in the pending state, retransmission is performed for the subsequent CG or CG bundle (i.e., the second CG resource or the second CG bundle), and automatic retransmission is performed according to NRU. (If the CG is a bundle, for other time domains or time-frequency domains or repetitions in the bundle except for this new transmission, it is still processed according to the current bundle, that is, transmit the existing, low-priority MAC PDUs).

[0279] Optionally, at this time, CGT is stopped, and / or at this time, LBT can succeed or fail.

[0280] A possible implementation manner is: the currently used CG resource (i.e., the first CG resource) performs a new transmission (using the CG resource). When the HARQ process is not in the pending state, a new transmission is performed for the subsequent CG or CG bundle (i.e., the second CG resource or the second CG bundle), and the transmission is performed in the autoTX manner. (That is, a new transmission is performed when at least one of the following conditions is met: obtaining the MAC PDU, the previous CG resource is deprioritized, and the corresponding PUSCH has not been completely transmitted).

[0281] Optionally, stop CGT at this time, and / or LBT can succeed or fail at this time.

[0282] A possible implementation is as follows: Retransmission is performed using the currently used CG resource (i.e., the first CG resource) (using the CG resource, for example, caused by LBT failure, not receiving DFI-ACK, etc.; for example, retransmission in a bundle; for the current CG resource (such as this low-priority resource), CGT is already running). And the HARQ process is in the not pending state (if CG is a bundle, for other repetitions of retransmission, it is processed according to the existing bundle retransmission, that is, for other repetitions in a bundle except this retransmission, it is still processed according to the current bundle, that is, transmit the existing, low-priority MAC PDUs). For subsequent CGs, or CG bundles (i.e., the second CG resource, or the second CG bundle), retransmission is performed according to NRU automatic retransmission.

[0283] Optionally, do not stop CGT at this time, and / or LBT can succeed or fail at this time.

[0326] The specific implementation process for the above Embodiment 3 is as follows:

[0327] The specific implementation process is as follows:

[0328] The gNB (network device) allocates CG resources to the UE (terminal device). When configuring the CG resources, the following parameters may be included:

[0329] Configure CGT;

[0330] Configure LCH-based prioritization;

[0331] Do not configure CGRT;

[0332] Do not configure autonomousTX;

[0333] In the above cases, the following implementation manners may be included but are not limited to:

[0334] When the CG resource is a low-priority resource (such as a resource considered low-priority due to a conflict, and at this time a valid MAC PDU for the CG packet is formed), the UE processes it according to the following table:

[0335] For example, during new transmission or retransmission (such as a bundle, such as retransmitting the CG via dynamic grant (DG)), if there is a CG resource with low priority due to LCH-based prioritization, or there is a CG resource with low priority due to CI-RNTI, or there is a CG resource with low priority due to a conflict with a high-priority PUCCH resource, the CGT corresponding to the CG resource is stopped. Correspondingly, for the next available CG resource, the MAC PDU of the low-priority CG resource is discarded and a new transmission packet is formed.

[0336] For example, during new transmission or retransmission (such as a bundle, such as the CG resource retransmitted via DG), if there is a CG resource with low priority due to LCH-based prioritization, or there is a CG resource with low priority due to CI-RNTI, or there is a CG resource with low priority due to a conflict with a high-priority PUCCH resource, the state of the CGT corresponding to the CG resource remains unchanged. Correspondingly, for the next available CG resource (in the case of CGT timeout), the MAC PDU of the low-priority CG resource is discarded and a new transmission packet is formed.

[0337] As a possible implementation, the timer state in the table can be determined according to the low-priority CG resource and / or the HARQ process state. The resource transmission mode can be determined according to at least one of the low-priority CG resource, the HARQ process state, and the timer state. The resource transmission mode can also be determined by other means, and the embodiments of the present invention do not limit this.

[0345] CG resources are low - priority resources (such as resources considered low - priority due to conflicts); in such cases, it may include but is not limited to the following implementation methods:

[0346] In an alternative implementation method: The currently used CG resource (i.e., the first CG resource) performs a new transmission (using the CG resource), and for subsequent CGs or CG bundles (i.e., the second CG resource or the second CG bundle), a new transmission is carried out to form a new MAC PDU packet (however, for other repetitions in the bundle except this new transmission, it is still processed according to the current bundle, that is, the existing, low - priority MAC PDUs are transmitted).

[0347] Optionally, at this time, the HARQ process can be in the not pending state or the pending state.

[0348] Optionally, at this time, CGT can be stopped or not stopped.

[0349] In another alternative implementation method: The currently used CG resource (i.e., the first CG resource) performs a re - transmission (using the CG resource), and for subsequent CGs or CG bundles (i.e., the second CG resource or the second CG bundle), it is re - transmitted according to the existing bundle processing (that is, for other repetitions in the bundle except this re - transmission, it is still processed according to the current bundle, that is, the existing, low - priority MAC PDUs are transmitted).
