[0054] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0055] The terms "first", "second", etc. in the specification, claims and the above-mentioned drawings of the embodiments of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in a sequence other than illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, the process, method, system, product or equipment comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment.
[0056] The following is an explanation of the terms involved in the embodiments of the present application:
[0057] Background of URLLC
[0058] In the URLLC of 5G access network 2 (5G RAN2 URLLC), it is stipulated that the transmission services of the 5G system need to support services such as industrial automation, transport automation, and intelligent power distribution. In actual applications, terminal devices usually transmit services based on configured grant (CG) resources. According to the figure, CG resources are configured by the network side device to the terminal device. After the configuration authorization is activated, the terminal device can communicate based on the CG resources.
[0059] In 5G RAN2 URLLC, in order to support the transmission of URLLC services, CG resources are enhanced, that is, multiple CG resource configurations are introduced, and the specific configuration and use of CG resources (such as supporting slot-level cycles, supporting automatic transmission of CG resources, etc.) are enhanced.
[0060] As services develop, Rel-17 needs to consider supporting URLLC services in interference-controlled NR-U scenarios. Specifically, it is possible to consider the enhanced use of NR-U CG resources and ULRRC CG resources in NR-U scenarios, that is, by coordinating the uplink grant configuration enhancements in NR-U and URLLC introduced in Rel-16 to make it applicable for unlicensed spectrum (Harmonizing UL configured-grant enhancements in NR-U and URLLC introduced in Rel-16 to be applicable for unlicensed spectrum).
[0061] CG resource enhancement in URLLC
[0062] To support the high latency requirements of URLLC services, URLLC enhances the CG resource cycle and supports any slot-level service cycle.
[0063] Specifically, in order to support multiple URLLC services and high latency requirements of URLLC services, URLLC introduces multiple CG resources. Different CG resources have different Hybrid Automatic Repeat Request (HARQ) processes, and the HARQ process identifier offset (harq-ProcID-Offset2) is used to ensure that the processes of different CG resources are different.
[0064] In actual applications, due to conflicts between CG resources and other resources, automatic transmission of CG resources is introduced to ensure that the MAC PDU (i.e., the Deprioritized MAC PDU) that has been packaged in the CG resources is not discarded and / or transmitted as soon as possible. For CG resources that have been packaged and cannot be transmitted due to resource conflicts, the CG resources in the subsequent CG configuration information of the same HARQ process can be used for new transmission. Exemplarily, the use of automatic transmission is determined by the automatic transmission flag (autonomousTx).
[0065] NR-U Related Background
[0066] In a certain project of 3GPP, the unlicensed working mode of NR is stipulated, and its goal is to make NR work in unlicensed frequency bands. Specifically, the NR-U system can include the following working scenarios:
[0067] Scenario A: In the carrier aggregation working scenario, the primary cell (Pcell) works on the licensed spectrum, and the secondary cell (Scell) works on the unlicensed spectrum through carrier aggregation.
[0068] In this working scenario, after the UE enters the connected state, it can communicate with the base station through multiple component carriers at the same time. The base station will specify a primary component carrier (PCC) for the UE through explicit configuration or according to the protocol agreement. The other component carriers are called secondary component carriers (SCC). The service cell on the primary component carrier (PCC) is called the primary service cell (Pcell), and the service cell on the secondary component carrier (SCC) is called the secondary service cell (Scell).
[0069] Scenario B: LTE and NR dual-connection working scenario, that is, when the terminal device works in the LTE and NR dual-connection scenario, the terminal device's primary service cell PCell can be the LTE licensed spectrum, and the terminal device's secondary service cell PScell can be the NR unlicensed spectrum. The dual-connection technology can achieve collaborative work between the LTE and NR systems, which helps to improve user rates and reduce switching delays.
[0070] Scenario C: Independent working scenario, the NR system works as an independent cell in the unlicensed spectrum.
[0071] Scenario D: NR single-cell scenario, the uplink (UL) transmission of the terminal device operates in the licensed spectrum, and the downlink (DL) operates in the unlicensed spectrum.
[0072] Scenario E: In the LTE and NR dual-connection working scenario, the primary service cell PCell of the terminal device can be the NR licensed spectrum, and the secondary service cell PScell can be the NR unlicensed spectrum.
[0073] Generally speaking, NR-U operates in 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 that have already worked in these unlicensed spectrums, such as WiFi. The principle of fairness is that the impact of NR-U on systems that have already been deployed in the unlicensed spectrum (such as WiFi) cannot exceed the impact between these systems.
[0074] In order to ensure fair coexistence between systems on 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 which is that before the transmission end device (base station or terminal) transmits data on the unlicensed spectrum, it needs to listen on the channel for a period of time as required, that is, to monitor whether there are other communication devices on the channel sending data. If the listening result indicates that the channel is idle, the transmission end device can transmit data to the receiving end device. If the listening result indicates that the channel is occupied, the transmission end device needs to back off for a period of time according to the regulations and continue to listen to the channel until the channel listening result is idle, and then it can transmit data to the receiving end device.
[0075] Generally, in order to ensure fairness, in one transmission, the duration that a communication device uses a channel of unlicensed spectrum for signal transmission cannot exceed the maximum channel occupancy time (MCOT).
[0076] The following is a brief introduction to the four channel access mechanisms specified in NR-U:
[0077] Mechanism 1: Direct transmission mechanism
[0078] Specifically, the direct transmission mechanism means that the transmitting end can quickly transmit after a switching gap within the channel occupancy time COT. The switching gap refers to the switching time of receiving the transmission. Usually, the switching time is short enough, and the typical value does not exceed 16us.
[0079] Mechanism 2: LBT mechanism without random backoff
[0080] Optional, this mechanism means that the time for the transmitter to listen to the channel is fixed, usually short, such as 25us.
[0081] Mechanism 3: LBT mechanism with random backoff (fixed contention window length)
[0082] In the LBT process, the transmitter randomly selects a random value in the contention window to determine the time to listen to the channel.
[0083] Mechanism 4: LBT mechanism with random backoff (contention window is not fixed)
[0084] In the LBT process, the transmitter randomly selects a random value in the contention window to determine the time to listen to the channel. The contention window is variable.
[0085] In summary, for terminal devices, the network device (base station) needs to transmit data to the terminal device within the MCOT time. If the network device does not seize the channel, that is, outside the MCOT time, the terminal device will not receive the scheduling data sent by the network device to the terminal device.
[0086] Uplink LBT failure in NR-U
[0087] For uplink transmission initiated by terminal devices, there are mainly the following categories:
[0088] 1. Uplink Scheduling Request (SR): used to request uplink resources; that is, if the terminal device has no uplink data to transmit, the base station does not need to allocate uplink resources to the terminal device, otherwise it will cause a waste of resources;
[0089] 2. Physical random access channel (PRACH) transmission: Due to RACH triggering, the terminal device needs to send message 1 (msg1);
[0090] 3. Physical uplink shared channel (PUSCH) transmission: including uplink data transmission based on configured grant and uplink data transmission based on dynamic grant;
[0091] 4. Physical layer signaling transmission: including confirmation and / or non-confirmation (ACK / NACK) information feedback, channel state information (CSI) reporting, etc.
[0092] On unlicensed bands, the terminal device needs to use LBT to monitor whether the channel is available before performing uplink transmission based on SR, PRACH or PUSCH. If it is not available, that is, LBT fails, the terminal device needs to wait until the next transmission opportunity to perform LBT again. If LBT failure is detected, the media access control (MAC) layer needs to be notified of the LBT failure.
[0093] CG asset enhancements in NR-U
[0094] In order to improve the flexibility of resource selection, the HARQ process of the NR-U CG resource is not calculated according to the formula, but is selected by the terminal device itself. For a CG resource, the radio resource control (RRC) configures a HARQ process set, and the terminal device can select a HARQ process from the HARQ process set for this CG resource transmission. Specifically, the HARQ process interval included in the configured HARQ process set is determined by the HARQ process identifier offset (harq-ProcID-Offset) and the HARQ process in NR (nr of HARQ-Processes).
[0095] Optionally, in order to support back-to-back resource configuration, multiple CG resources are introduced in NR-U, where multiple CG resources can share the HARQ process.
[0096] Optionally, in order to support automatic retransmission of resources when CG resources cannot be transmitted due to LBT failure, a CG retransmission timer (cg-Retransmission Timer) is introduced in NR-U. After the cg-Retransmission Timer times out, if the configured Grant Timer has not timed out, the HARQ process corresponding to the untransmitted CG resources can be retransmitted.
[0097] In practical applications, CG resource transmission can be interrupted by dynamically scheduled downlink control information (DCI) and downlink feedback information (DFI). For example, Table 1 shows the behavior of the CG timer and CG retransmission timer when CG resource transmission is interrupted by dynamically scheduled DCI and DFI.
[0098] Table 1
[0099]
[0100] From the above analysis, it can be seen that when supporting URLLC services in the interference controlled NR-U scenario, the network can configure ULRRRC CG resources and NR-U CG resources for the terminal device at the same time, but the two CG resources are used in different ways. Therefore, a method is urgently needed to coordinate the use of NR-UCG resources and ULRRRC CG resources to ensure information transmission between the terminal device and the network device.
[0101] It is worth noting that in the embodiments of the present application, the URLLC CG resource is: a CG configuration that supports high reliability and low latency services, or a CG configuration that supports uplink services on an authorized bandwidth or NR system, or a CG configuration that supports high reliability and low latency services on an authorized bandwidth or NR system, or a CG configuration that does not include specific configuration parameters. Optionally, the URLLC CG resource corresponds to the configuration, configuration method or usage mechanism of Rel-16 NR.
[0102] Optionally, the NR-U CG resource is: a CG configuration when the unlicensed spectrum or the NR-U system supports uplink services, or a CG configuration including a second specific configuration parameter. Optionally, the NR-U CG corresponds to the configuration or configuration method or usage mechanism of Rel-16 NR-U.
[0103] In view of the above problems, an embodiment of the present application provides an information transmission method. After receiving downlink information from a network device, the terminal device can determine the automatic transmission mode of at least one of the terminal device, HARQ process, and CG resource according to the configured CG resources and / or the indicated automatic transmission mode, and perform uplink transmission based on the automatic transmission mode. In this technical solution, when the terminal device is configured with two CG resources, it can determine the automatic transmission mode to be used, thereby ensuring information transmission between the terminal device and the network device.
[0104] Specifically, for the same terminal device, when NR-U CG resources and URLLC CG resources are configured at the same time, or when CG resources are configured in both URLLC CG mode and NR-U CG mode, the terminal device performs one of the following actions:
[0105] The same HARQ process and / or CG resource cannot support multiple automatic transmission modes;
[0106] The same HARQ process and / or CG resource is allowed to support multiple automatic transmission modes at the same time. At this time, the terminal device performs one of the following actions: always automatically transmits according to one of the modes, or automatically transmits according to a combination of modes.
[0107] Optionally, the above-mentioned automatic transmission modes are: URLLC CG automatic transmission mode corresponding to URLLC CG resources (i.e. configuring autonomous TX), and NR-U CG automatic retransmission mode corresponding to NR-U CG resources (i.e. configuring CG-retxtimer).
[0108] Before introducing the technical solution of the present application, the communication system to which the present application is applicable is first introduced.
[0109] For example, Figure 1 This is a schematic diagram of the structure of a communication system provided in an embodiment of the present application. Figure 1 As shown, the communication system may include a network device 110 and a plurality of terminal devices 120 located within the coverage area of the network device 110 . Figure 1 One network device 110 and two terminal devices 120 are shown by way of example.
[0110] Optionally, the communication system may include multiple network devices 110, and each network device may include another number of terminal devices 120 within its coverage area. The embodiment of the present application does not limit the number of network devices 110 and terminal devices 120 included in the communication system.
[0111] like Figure 1 As shown, wireless communication can be performed between the terminal device 120 and the network device 110. Device to device (D2D) communication can be performed between the terminal devices 120. Optionally, the network device 110 and the terminal device 120 and the terminal devices can communicate through a licensed spectrum, or through an unlicensed spectrum, or through both a licensed spectrum and an unlicensed spectrum. The embodiments of the present application do not limit the manner in which the network device and the terminal device, or between the terminal devices, communicate.
[0112] Understandably, Figure 1 This is only a schematic diagram.

[0114] Generally speaking, traditional communication systems support a limited number of connections and are easy to implement. However, with the development of communication technology, mobile communication systems will not only support traditional communications, but will also support, for example, device to device (D2D) communication, machine to machine (M2M) communication, machine type communication (MTC), and vehicle to vehicle (V2V) communication, etc. The embodiments of the present application can also be applied to these communication systems.

For the convenience of description, in all embodiments of the present application, the above-mentioned devices that provide wireless communication functions for terminal devices are collectively referred to as network devices.
[0117] In the embodiments of the present application, the terminal device may be any terminal, for example, the terminal device may be a user device for machine type communication. That is to say, the terminal device may also be referred to as user equipment (UE), mobile station (MS), mobile terminal, terminal, etc. The terminal device may communicate with one or more core networks via a radio access network (RAN). For example, the terminal device may be a mobile phone (or a "cellular" phone), a computer with a mobile terminal, etc. For example, the terminal device may also be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device, which exchanges language and / or data with a radio access network. This is not specifically limited in the embodiments of the present application.
[0118] Optionally, the network device and the terminal device can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on the water surface; can also be deployed on aircraft, balloons and artificial satellites in the air. The embodiments of the present application do not limit the application scenarios of the network device and the terminal device.
[0119] Below, based on Figure 1The communication system shown in the figure describes the technical solution of the present application in detail through specific embodiments. It should be noted that the technical solution of the present application may include part or all of the following contents, and the following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.
[0120] Figure 2 The interactive diagram of the first embodiment of the information transmission method provided in the embodiment of the present application. The method is explained by the information interaction between the terminal device and the network device. It can be understood that the network device can communicate with multiple terminal devices at the same time. In this embodiment, the interaction between one terminal device and the network device is explained. The execution scheme of other terminal devices is similar and will not be repeated in this embodiment.
[0121] In the embodiments of the present application, refer to Figure 2 As shown, the information transmission method may include the following steps:
[0122] S201. The network device generates downlink information according to the CG resources configured for the terminal device and / or the configured automatic transmission mode, wherein the downlink information includes at least one of the following: configuration information of the CG resources and indication information of the automatic transmission mode.
[0123] In the interference controlled NR-U scenario, in order to support URLLC services and ensure communication between network devices and terminal devices, the network devices will send certain configuration information to the terminal devices, such as available transmission resources, information transmission methods, etc.
[0124] As an example, when a network device configures a CG resource that a terminal device can use, it can also implicitly or explicitly configure an automatic transmission mode that the terminal device can use, and send it to the terminal device at the same time. At this time, the downlink information generated by the network device includes the configuration information of the CG resource. Optionally, the configuration information of the CG resource carries configuration parameters for transmission. Optionally, the automatic transmission mode is determined based on the configuration parameters.
[0125] As another example, the network device may also configure the CG resources that the terminal device can use and the automatic transmission mode that the terminal device can use, and send them to the terminal device respectively. At this time, the downlink information generated by the network device includes the indication information of the automatic transmission mode. Optionally, the network device may also send the configuration information of the CG resources before sending the indication information.
[0126] Optionally, when the network device configures CG resources for the terminal device, it may also configure an automatic transmission mode for the terminal device accordingly.
[0127] As an example, when configuring the first CG resource and the second CG resource for a terminal device, only the first automatic transmission mode or the second automatic retransmission mode is configured for the terminal device.
[0128] As another example, when configuring the first CG resources and the second CG resources for the terminal device, the first automatic transmission mode or the second automatic retransmission mode is configured only for each CG resource or each HARQ process or MAC entity or cell group or HARQ process group or CG resource group.
[0129] As another example, when only the first CG resource or the second CG resource is configured for the terminal device, the terminal device, each HARQ process, MAC entity or cell group, HARQ process group, CG resource group, and one of each CG resource are only configured with one automatic transmission mode.
[0130] As another example, when configuring the first CG resource and the second CG resource for the terminal device, multiple automatic transmission modes are configured for the terminal device at the same time. For example, when configuring the first CG resource and the second CG resource for the terminal device, the first automatic transmission mode and the second automatic retransmission mode are configured respectively.
[0131] As another example, when configuring the first CG resource or the second CG resource for the terminal device, multiple automatic transmission modes are configured for the terminal device at the same time, but ultimately one of the automatic transmission modes is used (such as determined by the UE or indicated by the network).
[0132] S202: The network device sends downlink information to the terminal device.
[0133] Optionally, in order to ensure uplink communication transmission between the terminal device and the network device, the network device can send the CG resources and / or the configured automatic transmission mode configured for the terminal device to the terminal device via downlink information, and accordingly, the terminal device can receive the downlink information from the network device.
[0134] S203. The terminal device determines the automatic transmission mode of the target object according to the above downlink information received from the network device. The target object is any one of the following: terminal device, MAC entity, cell group, HARQ process, CG resource.
[0135] As an example, when the downlink information includes configuration information for CG resources, that is, the configuration information includes at least specific CG configuration parameters, such as a CG retransmission timer (CG retx timer), the parameter can be used to indicate the transmission configuration parameters of the automatic transmission mode. At this time, the terminal device can determine the automatic transmission mode of at least one of the terminal device, MAC entity, cell group, HARQ process, and CG resource according to the configured CG resources and / or the specific CG configuration parameters in the configuration information.
[0136] As another example, when the downlink information includes indication information of the automatic transmission mode, or the downlink information includes configuration information of the CG resources and indication information of the automatic transmission mode, the network device configures the CG resources that the terminal device can use, and explicitly indicates the automatic transmission mode configured for it through the indication information. Therefore, the terminal device can determine the automatic transmission mode of at least one of the terminal device, MAC entity, cell group, HARQ process, and CG resource based on the configured CG resources and indication information.
[0137] It is understandable that the target object is illustrated as at least one of a terminal device, a MAC entity, a cell group, a HARQ process, and a CG resource in the embodiment of the present application. In practical applications, the target object may also be at least one of a HARQ process group and a CG group. The embodiment of the present application does not limit the specific form of the target object, which can be determined according to the actual scenario and will not be repeated here.
[0138] Optionally, when receiving downlink information, the terminal device first determines the configured CG resources and / or configured transmission configuration parameters based on the above-mentioned configuration information, and then determines the automatic transmission mode of the target object based on the configured CG resources and / or configured transmission configuration parameters, and / or determines the automatic transmission mode of the target object based on the configuration information and indication information included in the downlink information.
[0139] It can be understood that in an embodiment of the present application, the automatic transmission mode may include: a first automatic transmission mode and a second automatic retransmission mode. Among them, the first automatic transmission mode is the URLLC CG automatic transmission mode (that is, configured with the parameter autonomousTX), and the second automatic retransmission mode is the NR-U CG automatic retransmission mode (that is, configured with the parameter CG-retxtimer). Optionally, the automatic transmission mode of the target object can be an existing mode or an enhanced mode, which will not be repeated here.
[0140] Exemplarily, the automatic transmission method of the target object expected by the terminal device includes at least one of the following:
[0141] The terminal device expects that only one automatic transmission mode is configured for the same HARQ process and / or CG resource;
[0142] The terminal device expects that only one automatic transmission mode is configured for the same HARQ process group and / or CG resource group;
[0143] The terminal device expects that only one automatic transmission mode is configured for the same MAC entity or cell group;
[0144] The terminal device expects only one automatic transmission mode to be configured.
[0145] Specifically, the terminal device expects that at least one of the same HARQ process, CG resource, the same HARQ process group, CG resource group, terminal device, MAC entity, and cell group is configured with only the first automatic transmission mode or the second automatic retransmission mode.
[0146] Exemplarily, the automatic transmission method of the target object includes any one of the following:
[0147] Only one automatic transmission mode is configured for the same HARQ process and / or CG resource;
[0148] Only one automatic transmission mode is configured for the same HARQ process group and / or CG resource group;
[0149] The same MAC entity or cell group of the terminal device is configured with only one automatic transmission mode;
[0150] The same terminal device is configured with only one automatic transmission mode.
[0151] Specifically, when the CG resources configured by the configuration information meet the first condition, the terminal device determines, based on the received downlink information, that the network device is only configured with the first automatic transmission mode or the second automatic retransmission mode for at least one of the same HARQ process, CG resources, the same HARQ process group, CG resource group, terminal device, MAC entity, and cell group.
[0152] In the above examples, the configuration information of the CG resource or the automatic transmission method of the target object satisfies at least one of the following:
[0153] For the same terminal device or MAC entity or CG resource, the first CG resource and the second CG resource are configured at the same time, that is, the network device configures the NR-U CG resource and the URLLC CG resource for the same terminal device or CG resource at the same time;
[0154] For the same terminal device or MAC entity or CG resource, the CG resource includes a first CG resource configured in a first manner and a second CG resource configured in a second manner, that is, the network device configures the CG resource or configures the CG resource of the terminal device in both the URLLC CG manner and the NR-UCG manner;
[0155] For the same terminal device or MAC entity or CG resource, the CG resource is transmitted in the first mode and the second mode, that is, the network device transmits the CG resource in both the URLLC CG mode and the NR-U CG mode for the same terminal device or CG resource;
[0156] For the same terminal device or MAC entity or CG resource, the CG resource is transmitted in the first mode or the second mode, that is, the network device transmits the CG resource in the URLLC CG automatic transmission mode or transmits the CG resource in the NR-U CG automatic retransmission mode for the same terminal device or CG resource;
[0157] For the same terminal device or MAC entity or CG resource, only the first CG resource or the second CG resource is configured, that is, the network device only configures the URLLC CG resource, or only configures the NR-U CG resource for the same terminal device or CG resource;
[0158] For the same terminal device or MAC entity or CG resource, the CG resources include a first CG resource configured in a first manner or a second CG resource configured in a second manner, that is, the CG resources configured by the network device or the CG resources configured for the same terminal device include URLLC CG resources configured in a URLLC CG manner, or NR-U CG resources configured in a NR-U CG manner.
[0159] Optionally, in an embodiment of the present application, before executing step S203, the terminal device may further execute the following steps:
[0160] According to the configuration information, corresponding CG resources are configured for the terminal device;
[0161] Determine if the target object supports and / or is configured for automatic transfer.
[0162] Exemplarily, based on the received configuration information, the terminal device can determine the CG resources configured by the network device, for example, configuring the first CG resource and the second CG resource at the same time, or configuring the first CG resource in the first way and configuring the second CG resource in the second way at the same time, or configuring only the first CG resource or only the second CG resource, or configuring only the first CG resource in the first way, or configuring only the second CG resource in the second way. The embodiments of the present application are not limited to the specific resources configured by the terminal device, which can be determined based on the configuration information of the network device, which will not be repeated here.
[0163] In the embodiments of the present application, the first CG resource is a URLLC CG resource, the second CG resource is a NR-U CG resource, the first mode is a URLLC CG mode, and the second mode is a NR-U CG mode for explanation. Other names may be used and are not limited here.
[0164] In addition, the terminal device can determine whether at least one of the terminal device, HARQ process, CG resource, and MAC entity supports and / or configures automatic transmission based on the received configuration information or / or the above-mentioned indication information. For example, the terminal device can determine whether the target object is configured and / or supports automatic transmission, and / or how to perform automatic transmission based on whether the configuration information carries transmission configuration parameters and / or whether the indication information is received.
[0165] Exemplarily, when the configuration information does not carry transmission configuration parameters and no indication information is received, it is determined that the target object does not support the automatic transmission mode; when the configuration information carries transmission configuration parameters and / or indication information is received, it is determined that the target object is configured and / or supports the automatic transmission mode, and / or the automatic transmission mode is used.
[0166] S204: The terminal device performs uplink transmission based on the automatic transmission mode.
[0167] Optionally, in an embodiment of the present application, after the terminal device determines the automatic transmission mode of the target object according to the received downlink information, it can perform uplink transmission based on the automatic transmission mode of the target object.
[0168] In actual applications, when the terminal device determines that the target object supports and / or is configured for automatic transmission, the terminal device can perform automatic transmission and / or automatic retransmission on the CG resource corresponding to the target object based on the determined automatic transmission method.
[0169] Specifically, step S204 can be implemented through different steps according to different target objects, as follows:
[0170] As an example, when the target object is a terminal device, uplink transmission is performed using an automatic transmission mode configured for the terminal device and / or supported by the terminal device.
[0171] As another example, when the target object is a CG resource group or CG resource or HARQ process or HARQ process group or cell group, for different CG resource groups or CG resources or HARQ processes or MAC entities or cell groups, the automatic transmission method corresponding to each object is used for uplink transmission.
[0172] The information transmission method provided in the embodiment of the present application is that the network device generates downlink information according to the CG resources configured for the terminal device and / or the configured automatic transmission method, and sends the downlink information to the terminal device. The downlink information includes at least one of the following: configuration information of the CG resources, indication information of the automatic transmission method. The terminal device determines the automatic transmission method of the target object according to the received downlink information, and performs uplink transmission based on the automatic transmission method. The target object is any one of the following: terminal device, HARQ process, CG resource. In this technical solution, when the terminal device is configured with at least one CG resource, the terminal device can determine the automatic transmission method that can be used, thereby ensuring information transmission between the terminal device and the network device.
[0173] Based on the above embodiments, Figure 3 This is an interactive diagram of the second embodiment of the information transmission method provided in the embodiment of the present application. Figure 3 As shown, before the above S201, the method may further include the following steps:
[0174] S301. The terminal device sends transmission capability information to the network device.
[0175] The transmission capability information includes at least one of the following: whether multiple automatic transmission capabilities are supported simultaneously, and the supported automatic transmission capabilities.
[0176] Specifically, the terminal device can determine its transmission capability according to its own performance, and then send it to the network device, so that the network device can automatically transmit the data in the manner expected by the terminal device.
[0177] In one possible design of the present application, the transmission capability information specifically refers to the terminal device supporting multiple automatic transmission capabilities and / or supporting multiple automatic transmission capabilities at the same time. In another possible design of the present application, the transmission capability information specifically refers to the terminal device not being able to support multiple automatic transmission capabilities at the same time and / or supporting one automatic transmission capability.
[0178] Exemplarily, the automatic transmission capability supported by the terminal device includes at least one of the following:
[0179] Only the first automatic transmission mode is supported, such as the URLLC CG automatic transmission mode (if the parameter autonomousTX is configured);
[0180] Only the second automatic transmission mode is supported, such as the NR-U CG automatic retransmission mode (if the parameter CG-retxtimer is configured);
[0181] It supports both the first automatic transmission mode and the second automatic transmission mode, such as supporting both the URLLC CG automatic transmission mode (i.e., configured with the parameter autonomousTX) and the NR-U CG automatic retransmission mode (i.e., configured with the parameter CG-retxtimer).
[0182] It can be understood that, in the embodiment of the present application, the transmission capability information reported by the terminal device is information of any of the following granularities:
[0183] Data resource block, terminal device, MAC entity, cell group, CG resources, HARQ process.
[0184] Specifically, the terminal device may upload the transmission capability information of each data resource block, the transmission capability information of the terminal device, the transmission capability information of each CG resource, or the transmission capability information of each HARQ process. Furthermore, the transmission capability information may also be information of granularity such as MAC entity, cell group, HARQ process group, CG group, etc. The embodiment of the present application does not limit the granularity of the transmission capability information, which can be determined according to the scenario in which the terminal device is located, and will not be repeated here.
[0185] S302: The network device determines the automatic transmission mode configured for the target object according to the received transmission capability information.
[0186] In an embodiment of the present application, when the network device receives the transmission capability information of the terminal device, it can configure an automatic transmission mode for the target object according to the automatic transmission capability supported by the terminal device.
[0187] Exemplarily, when the terminal device supports two automatic transmission capabilities, two automatic transmission modes can be configured for the target object, or only one automatic transmission mode can be configured for the target object. When the terminal device supports only one automatic transmission capability, only one automatic transmission mode can be configured for the target object.
[0188] The automatic transmission method specifically configured by the network device for the target object can be set according to actual needs and will not be elaborated here.
[0189] The information transmission method provided in the embodiment of the present application, the terminal device sends transmission capability information to the network device, so that the network device can configure an automatic transmission mode for the target object according to the received transmission capability information, thereby improving the matching degree between the configured automatic transmission mode and the transmission capability information of the terminal device, and improving the transmission performance between the network device and the terminal device.
[0190] Exemplarily, based on the above embodiments, Figure 4This is an interactive diagram of the third embodiment of the information transmission method provided in the present application. The execution subject of this embodiment is a terminal device. Figure 4 As shown, the above S203 can be implemented by the following steps:
[0191] S401. Determine the configured CG resources and configured transmission configuration parameters based on the above configuration information.
[0192] In an embodiment of the present application, when the network device configures CG resources for the terminal device, it can also configure the transmission configuration parameters corresponding to the automatic transmission mode, and send them to the terminal device through the configuration information. Therefore, the terminal device can determine the configured CG resources and the configured transmission configuration parameters based on the configuration information in the downlink information.
[0193] Exemplarily, the configured CG resource may be only the first CG resource, or only the second CG resource, or the first CG resource and the second CG resource. The configuration information of the CG resource includes parameters autonomousTX and / or CG-retxtimer.
[0194] S402. Determine the automatic transmission method of the target object according to the configured CG resources and / or transmission configuration parameters.
[0195] Exemplarily, the terminal device can determine the automatic transmission mode of the terminal device, each CG resource, and at least one of each HARQ process based on whether the network device configures one CG resource or two CG resources, and / or whether the configuration information of the CG resource includes specific configuration parameters, such as including autonomousTX and / or CG-retx timer.
[0196] Exemplarily, when the terminal device is configured with the first CG resource and the second CG resource, the terminal device is only configured and / or only supports the first automatic transmission mode or the second automatic retransmission mode. That is, when the terminal device is configured with the NR-U CG resource and the URLLC CG resource, the terminal device is only configured and / or only supports the URLLC CG automatic transmission mode or the NR-U CG automatic retransmission mode.
[0197] Exemplarily, when the terminal device is configured with the first CG resource and the second CG resource, each CG resource or each HARQ process is only configured and / or only supports the first automatic transmission mode or the second automatic retransmission mode. That is, when the terminal device is configured with NR-U CG resources and URLLC CG resources, the same CG resource or the same HARQ process is only configured and / or only supports the URLLC CG automatic transmission mode and the NR-UCG automatic retransmission mode. However, for the UE, multiple sets of automatic transmission modes can be configured at the same time, optionally.
[0198] Exemplarily, when the terminal device is configured with the first CG resource and the second CG resource, the terminal device limits the terminal device and / or each CG resource and / or each HARQ process to transmit information only according to one automatic transmission mode or a combination of two automatic transmission modes. That is, when the terminal device is configured with NR-U CG resources and URLLC CG resources, the terminal device limits the automatic transmission mode of the terminal device and / or the same CG resource and / or the same HARQ process to the URLLC CG automatic transmission mode or the NR-U CG automatic retransmission mode or the combination of the URLLC CG automatic transmission mode and the NR-U CG automatic retransmission mode. In other words, at least one set can be configured, but only one of them is used.
[0199] The information transmission method provided in the embodiment of the present application is that the terminal device determines the configured CG resources and the configured transmission configuration parameters based on the above-mentioned configuration information, and determines the automatic transmission method of the target object based on the configured CG resources and / or transmission configuration parameters, which lays the foundation for the subsequent terminal device to perform uplink transmission.
[0200] Exemplarily, based on the above embodiments, Figure 5 The interactive diagram of the fourth embodiment of the information transmission method provided in the embodiment of the present application. The execution subject of this embodiment is a terminal device. Figure 5 As shown, when the downlink information includes: configuration information of CG resources and indication information of automatic transmission mode, the above S203 can be implemented by the following steps:
[0201] S501. Determine the configured CG resources according to the configuration information.
[0202] The specific implementation of this step is the same as above Figure 4 The method of determining CG resources based on configuration information as recorded in S401 in the illustrated embodiment is consistent and will not be repeated here.
[0203] S502: Determine the configured automatic transmission mode according to the indication information.
[0204] In an embodiment of the present application, the network device may configure the automatic transmission mode through indication information. Exemplarily, the indication information is received from the network device through broadcast signaling and / or dedicated signaling, or the indication information is obtained when receiving configuration information of the CG resource.
[0205] Exemplarily, the dedicated signaling may be any one of a radio resource control (RRC) signaling, a medium access control control element (MAC Control Element, MAC CE), and DCI.
[0206] Optionally, the indication information may be a parameter for a single terminal device, a parameter for a single CG resource, a parameter for a single CG resource group, a parameter for a single HARQ process, a parameter for a single MAC entity, or a parameter for a single cell group.
[0207] Exemplarily, the automatic transmission mode configured by the indication information may be a URLLC CG automatic transmission mode or a NR-U CG automatic retransmission mode. Optionally, it may be an existing mode or an enhanced mode. The embodiment of the present application does not limit the automatic transmission mode of the specific configuration, which can be determined according to the actual scenario and is not determined here.
[0208] S503. Determine the automatic transmission method of the target object according to the configured CG resources and the configured automatic transmission method.
[0209] Optionally, the terminal device may determine the automatic transmission mode of the target object according to the specific resource of the configured CG resource and / or the configured automatic transmission mode.
[0210] Accordingly, in a possible design, the above S204 can be implemented specifically through the following steps:
[0211] Automatic transmission is performed according to at least one of the configured automatic transmission mode, configuration parameters and different CG resources.
[0212] As an example, if the CG resource configured by the terminal device is the second CG resource, the second CG resource or the HARQ process of the second CG resource shall be transmitted in accordance with the first automatic transmission mode when any of the following conditions are met: the configured automatic transmission mode is the first automatic transmission mode, the second automatic retransmission mode is not supported, the second automatic retransmission parameters are not configured, only the first automatic transmission mode is supported, and only the first automatic transmission parameters are configured. Correspondingly, the automatic transmission mode of the second CG resource or the HARQ process of the second CG resource is the first automatic transmission mode.
[0213] As another example, if the CG resource configured by the terminal device is the second CG resource, the second CG resource or the HARQ process of the second CG resource satisfies any of the following conditions, and is transmitted in accordance with the second automatic transmission mode: the indication information indicates that the configured automatic transmission mode is the second automatic retransmission mode, only supports the second automatic retransmission mode, only configures the second automatic retransmission parameters, does not support the first automatic transmission mode, and does not configure the first automatic transmission parameters. Correspondingly, the automatic transmission mode of the second CG resource or the HARQ process of the second CG resource is the second automatic retransmission mode.
[0214] As another example, if the configured automatic transmission mode is the second automatic transmission mode, the CG resource of the terminal device or the HARQ process of the CG resource satisfies any of the following: only supports the second automatic retransmission mode, only configures the second automatic retransmission parameters, does not support the first automatic transmission mode, and does not configure the first automatic transmission parameters. That is, when the CG resource configured by the terminal device is the first CG resource or the second CG resource (NRU CG or URLLC CG), the automatic transmission mode of the CG resource of the terminal device or the HARQ process of the CG resource is the second automatic retransmission mode.
[0215] As another example, if the configured automatic transmission mode is the first automatic transmission mode, the CG resource of the terminal device or the HARQ process of the CG resource satisfies any one of the following: does not support the second automatic retransmission mode, does not configure the second automatic retransmission parameter, only supports the first automatic transmission mode, and only configures the first automatic transmission parameter. That is, when the CG resource configured by the terminal device is the first CG resource or the second CG resource (NRU CG or URLLC CG), the automatic transmission mode of the CG resource of the terminal device or the HARQ process of the CG resource is the first automatic transmission mode.
[0216] In an embodiment of the present application, URLLC CG resources can be configured with NR-U CG automatic retransmission mode or URLLC CG automatic transmission mode, and NRU CG resources can also be configured with NR-U CG automatic retransmission mode or URLLC CG automatic transmission mode. Optionally, the configured automatic transmission mode can be an existing mode or an enhanced mode, which will not be described here. The embodiments of the present application do not limit it.
[0217] In another possible design, the above S204 may be implemented specifically through the following steps:
[0218] Automatic transmission is performed according to at least one of a configured automatic transmission mode, configuration parameters, and different objects.
[0219] As an example, when different CG resources or different HARQ processes are configured with different automatic transmission modes, if the CG resource or the CG resource corresponding to the HARQ process is the second CG resource, then the CG resource or the HARQ process of the CG resource satisfies any one of the following: only supports the second automatic retransmission mode, only configures the second automatic retransmission parameters, does not support the first automatic transmission mode, and does not configure the first automatic transmission parameters. Correspondingly, the automatic transmission mode of the CG resource or the HARQ process of the CG resource is the second automatic retransmission mode.
[0220] As another example, when different CG resources or different HARQ processes are configured with different automatic transmission modes, if the CG resource or the CG resource corresponding to the HARQ process is the second CG resource, the CG resource or the HARQ process of the CG resource satisfies any one of the following: does not support the second automatic retransmission mode, does not configure the second automatic retransmission parameters, only supports the first automatic transmission mode, and only configures the first automatic transmission parameters. Correspondingly, the automatic transmission mode of the CG resource or the HARQ process of the CG resource is the first automatic transmission mode.
[0221] As another example, when different CG resources or different HARQ processes are configured with different automatic transmission modes, if the CG resource or the CG resource corresponding to the HARQ process is the first CG resource, then the CG resource or the HARQ process of the CG resource satisfies any one of the following: only supports the second automatic retransmission mode, only configures the second automatic retransmission parameters, does not support the first automatic transmission mode, and does not configure the first automatic transmission parameters. Correspondingly, the automatic transmission mode of the CG resource or the HARQ process of the CG resource is the second automatic retransmission mode.
[0222] As another example, when different CG resources or different HARQ processes are configured with different automatic transmission modes, if the CG resource or the CG resource corresponding to the HARQ process is the first CG resource, the CG resource or the HARQ process of the CG resource satisfies any one of the following: does not support the second automatic retransmission mode, does not configure the second automatic retransmission parameters, only supports the first automatic transmission mode, and only configures the first automatic transmission parameters. Correspondingly, the automatic transmission mode of the CG resource or the HARQ process of the CG resource is the first automatic transmission mode.
[0223] It can be understood that in the embodiments of the present application, the configured automatic transmission mode can be an existing mode or an enhanced mode, which will not be described in detail here.
[0224] The information transmission method provided in the embodiment of the present application is that the terminal device determines the configured CG resources according to the configuration information, determines the configured automatic transmission method according to the indication information, and finally determines the automatic transmission method of the target object according to the configured CG resources and the configured automatic transmission method. In this technical solution, the terminal device determines the automatic transmission method of the target object according to the configuration information and the indication information, and can accurately determine the available automatic transmission method, which lays the foundation for the implementation of subsequent uplink transmission.
[0225] Further, on the basis of the above embodiment, when the terminal device only configures and / or supports the first CG resource or the second CG resource, the terminal device, each HARQ process, and each CG resource only support and / or configure one automatic transmission mode. That is, the terminal device, each HARQ process, and each CG resource only support and / or configure the URLLC CG automatic transmission mode or the NR-U CG automatic retransmission mode.
[0226] Exemplarily, in a possible design of the present application, when the terminal device is configured with a first CG resource and a second CG resource, and the terminal device simultaneously supports and / or is configured with multiple automatic transmission modes, each HARQ process and / or each CG resource and / or MAC entity or cell group only supports and / or is configured with only one automatic transmission mode.
[0227] Accordingly, the above S204 (uplink transmission based on automatic transmission mode) can be implemented by the following steps:
[0228] When the target object is a terminal device, a MAC entity or a cell group, the corresponding automatic transmission method is used for uplink transmission for different CG resource groups, CG resources or HARQ processes.
[0229] In another possible design of the present application, the terminal device may also meet the following conditions:
[0230] When the terminal device configures the first CG resource and the second CG resource, the terminal device is allowed to configure multiple automatic transmission modes at the same time, but at least one of the different CG resources, MAC entities, cell groups, and HARQ processes is only allowed to be configured with one automatic transmission mode; or, when the terminal device configures the first CG resource and the second CG resource, for the same HARQ process and / or the same CG resource and / or the same MAC entity and / or the same cell group, the terminal device is allowed to simultaneously support and / or configure multiple automatic transmission modes.
[0231] Accordingly, the above S204 (uplink transmission based on the automatic transmission mode) can be implemented by at least one of the following steps:
[0232] Performing uplink transmission according to one of a plurality of automatic transmission modes;
[0233] Uplink transmission is performed jointly according to the first automatic transmission mode and the second automatic retransmission mode.
[0234] Exemplarily, uplink transmission is performed according to one of multiple automatic transmission modes, including any one of the following:
[0235] Perform uplink transmission according to the first automatic transmission mode, that is, perform uplink transmission according to the URLLC CG automatic transmission mode;
[0236] Perform uplink transmission according to the second automatic retransmission mode, that is, perform uplink transmission according to the NR-U CG automatic retransmission mode;
[0237] Determine the target automatic transmission mode to be used according to the received indication information or predefined information, and use the target automatic transmission mode to perform uplink transmission;
[0238] When the first unit in the CG resource or the HARQ process meets the second condition, the first automatic transmission mode is used for uplink transmission;
[0239] When the first unit in the CG resource or HARQ process meets the third condition, the second automatic retransmission mode is used for uplink transmission.
[0240] The second condition includes at least one of the following:
[0241] The first transmission resource of the first unit cannot be transmitted or is not completed or is not successfully transmitted due to resource conflict;
[0242] The transmission resource of the first unit fails to transmit or is not completed or is not successfully transmitted due to resource conflict;
[0243] The first unit is a low priority media access control protocol data unit.
[0244] The third condition includes at least one of the following:
[0245] The first transmission resource of the first unit fails to be transmitted or is not successfully transmitted due to a listening failure or receiving a listening failure indication;
[0246] The transmission resource of the first unit fails to transmit or fails to transmit successfully due to a listening failure or receiving a listening failure indication.
[0247] Exemplarily, performing uplink transmission together according to the first automatic transmission mode and the second automatic retransmission mode includes at least one of the following:
[0248] Perform uplink transmission using the automatic transmission mode indicated by network instruction information at different times;
[0249] When the first transmission resource of the first unit in the CG resource or HARQ process fails to be transmitted or is not completed or is not successfully transmitted, uplink transmission is performed together according to the first automatic transmission mode and the second automatic retransmission mode;
[0250] For the CG resource or the first transmission resource of the first unit in the HARQ process, if the first unit fails to transmit or fails to complete or successfully transmits using the first automatic transmission mode for multiple times, information transmission is performed according to the second automatic retransmission mode, and / or uplink transmission is performed together according to the first automatic transmission mode and the second automatic retransmission mode;
[0251] For the CG resources or the first transmission resources of the first unit in the HARQ process, if the first unit fails to transmit or fails to complete or successfully transmits using the second automatic retransmission method for multiple times, information is transmitted according to the first automatic transmission method, and / or uplink transmission is performed jointly according to the first automatic transmission method and the second automatic retransmission method.
[0252] Optionally, the above automatic transmission method can be an existing method or an enhanced method, which will not be described in detail here.
[0253] It can be understood that, in the embodiment of the present application, the first unit is a media access control protocol data unit (MAC PDU).
[0254] Optionally, in any of the above embodiments of the present application, when the downlink information includes indication information, the indication information is also used to limit the number of automatic transmissions in the automatic transmission mode.
[0255] Exemplarily, the number of automatic transmissions in the automatic transmission mode is any one of the following:

[0257] The number of automatic retransmissions in the second automatic retransmission mode;
[0258] The total number of automatic transmission times in the first automatic transmission mode and the number of automatic retransmission times in the second automatic retransmission mode.
[0259] Furthermore, in an embodiment of the present application, the method may further include the following steps:
[0260] The network device sends scheduling information to the terminal device, where the scheduling information is used to indicate the transmission or use information of the corresponding HARQ process or CG resource;
[0261] Accordingly, the above S204 can be implemented by the following steps:
[0262] The terminal device performs uplink transmission according to the received scheduling information and the determined automatic transmission mode.
[0263] The scheduling information is information received before the first unit in the HARQ process performs automatic transmission or automatic transmission succeeds, and the scheduling information is dynamic scheduling information or downlink feedback information.
[0264] As an example, the scheduling information is dynamic scheduling information; accordingly, uplink transmission according to the scheduling information and the automatic transmission mode can be implemented by the following steps:
[0265] If the dynamic scheduling information is used to indicate scheduling of dynamically granted resources for new transmission or retransmission, at least one of the following is performed for the HARQ process or the first unit:

[0267] Stop configuring the grant retransmission timer;
[0268] Stop configuring the authorization timer;
[0269] When the transmission of the dynamic authorization resource is executed, the configuration authorization timer is started;
[0270] When dynamic authorization resource transmission is performed, the configuration authorization retransmission timer is not started.
[0271] As another example, the scheduling information is downlink feedback information; accordingly, uplink transmission according to the scheduling information and the automatic transmission mode can be implemented by the following steps:
[0272] If the downlink feedback information is confirmation information, at least one of the following is performed for the HARQ process or the first unit:
[0273] Stop the automatic transmission corresponding to the first automatic transmission mode;
[0274] Stop configuring the grant retransmission timer;
[0275] Stop configuring the authorization timer;
[0276] If the downlink feedback information is non-confirmation information, performing at least one of the following steps for the HARQ process or the first unit:
[0277] The automatic transmission corresponding to the first automatic transmission mode is not stopped;
[0278] Stop configuring the grant retransmission timer;
[0279] Do not stop configuring the authorization timer;
[0280] When the corresponding HARQ process or the transmission of the first unit is executed, the configuration authorization retransmission timer is restarted.
[0281] In addition, in an embodiment of the present application, the method may further include:
[0282] When the HARQ process corresponding to the CG resource or the first unit transmission of the HARQ process is executed, the configuration authorization retransmission timer is started.
[0283] Specifically, when the HARQ process or the first unit in the HARQ process performs a new transmission or a first transmission or a last transmission and / or the first unit in the HARQ process meets the fourth condition, the configuration authorization retransmission timer is started.
[0284] Optionally, the HARQ process or the first unit in the HARQ process performs a new transmission or a first transmission or a last transmission, including at least one of the following:
[0285] The HARQ process or the first unit in the HARQ process performs a new transmission or a first transmission or a last transmission according to the second automatic retransmission mode;
[0286] The HARQ process or the first unit in the HARQ process performs a new transmission or a first transmission or a last transmission together according to the first automatic transmission mode and the second automatic retransmission mode.
[0287] Optionally, the first unit in the HARQ process satisfies the fourth condition, including at least one of the following:
[0288] There is a low priority first unit package in the CG resource;

[0290] The first unit was not transmitted or was not successfully transmitted or was not completely transmitted due to resource conflict;
[0291] The first unit is a low priority media access control protocol data unit.
[0292] Furthermore, in an embodiment of the present application, the information transmission method may further include the following steps:
[0293] When the HARQ entity obtains the first unit, the state of the HARQ process corresponding to the HARQ entity is set to a pending state; or, when the HARQ process is configured with an authorization retransmission timer and the HARQ entity corresponding to the HARQ process obtains the first unit, the state of the HARQ process is set to a pending state.
[0294] In addition, in an embodiment of the present application, the information transmission method may further include the following steps:
[0295] When the HARQ process or CG resources meet the fifth condition and the HARQ entity corresponding to the HARQ process obtains the first unit, the state of the HARQ process is set to a pending state.
[0296] The fifth condition includes at least one of the following:
[0297] The HARQ process corresponds to CG resources;
[0298] Transmitting according to a second automatic retransmission mode;
[0299] Transmitting in accordance with a first automatic transmission mode and a second retransmission mode;
[0300] The first unit has been packaged but not transmitted or not successfully transmitted or not completely transmitted;

[0305] Exemplarily, the first unit is obtained including at least one of the following:
[0306] The resource used to transmit the first unit is a CG resource;
[0307] The resource used to transmit the first unit is a high priority resource;

[0310] The HARQ process corresponding to the first unit is in a pending state;
[0311] The CG resource size of the transmitted first unit is the same as the size of the first unit.
[0312] To summarize, in the information transmission method provided in the embodiment of the present application, when the network device configures one CG resource or two CG resources for the terminal device, the terminal device can determine the automatic transmission mode of at least one of the terminal device, HARQ process, and CG resources based on the received configuration information of the CG resources and / or the indication information of the automatic transmission mode, and perform uplink transmission based on the automatic transmission mode. In particular, when two CG resources are set at the same time, the use of the two CG resources can be coordinated, thereby ensuring the information transmission performance between the terminal device and the network device.
[0313] The technical solution of the present application is described in detail below through two specific embodiments. Specific embodiment 1
[0315] In the NR-U system supporting URLLC services, the network device may restrict the same HARQ process and / or CG resources and / or MAC entity and / or cell group and / or HARQ process group and / or CG group from supporting multiple automatic transmission modes when configuring NR-U CG resources and URLLC CG resources for the same UE at the same time, or configuring CG resources according to the URLLC CG mode and the NR-U CG mode at the same time. That is, the same HARQ process and / or CG resources and / or MAC entity and / or cell group and / or HARQ process group and / or CG group only supports one automatic transmission mode, or the network device does not configure multiple automatic transmission modes or only configures one automatic transmission mode for the same HARQ process and / or CG resources and / or MAC entity and / or cell group and / or HARQ process group and / or CG group, so that the UE can transmit according to the automatic transmission mode.
[0316] The specific implementation process is as follows:
[0317] First, when the network device configures a CG resource for the UE or configures multiple CG resources at the same time, the network device only configures one automatic transmission mode for the UE or CG resource or HARQ process.
[0318] 1. For a UE or a CG resource or a HARQ process and / or a MAC entity and / or a cell group and / or a HARQ process group and / or a CG group, the network device configures NR-U CG resources and URLLC CG resources at the same time.
[0319] 2. For a UE or a CG resource, when URLLC CG resources and NR-U CG resources are configured at the same time, or when CG resources are configured according to the URLLC CG mode and the NR-U CG mode at the same time, for the UE, the UE is restricted from being configured with multiple automatic transmission modes at the same time.
[0320] Optional, multiple automatic transmission modes include: URLLC CG automatic transmission mode (i.e. configuring autonomousTX), NR-U CG automatic retransmission mode (i.e. configuring CG-retx timer).
[0321] 3. For a UE or a CG resource, when NR-U CG resources and URLLC CG resources are configured at the same time, or when CG resources are configured according to the URLLC CG method and the NR-U CG method at the same time, for a HARQ process or CG resource and / or MAC entity and / or cell group and / or HARQ process group and / or CG group, the UE is restricted from being configured with multiple automatic transmission modes at the same time.
[0322] Optional, multiple automatic transmission modes include: URLLC CG automatic transmission mode (i.e. configuring autonomousTX), NR-U CG automatic retransmission mode (i.e. configuring CG-retx timer).
[0323] 4. The network device indicates the automatic transmission mode to be adopted through the first indication information.
[0324] Optionally, the first indication information may be indicated to the UE via broadcast / dedicated signaling (any one of RRC, MAC CE, and DCI).
[0325] Optionally, the first indication information can be notified to the UE when configuring CG resources.
[0326] Optionally, the first indication information may be an indication parameter per UE, an indication parameter per CG, an indication parameter per CG group, an indication parameter per HARQ process, an indication parameter per HARQ process group, a MAC entity, a cell group parameter, etc. This application does not limit it.
[0327] 5. As an example, if the network device configures NR-U CG resources and URLLC CG resources for the UE, for the UE, only one automatic transmission mode can be configured for the UE, that is, either URLLC CG automatic transmission mode (that is, configuring autonomousTX) or NR-U CG automatic retransmission mode (that is, configuring CG-retx timer). Optionally, it can be an existing mode or an enhanced mode.
[0328] Optionally, if the configured automatic transmission mode is the URLLC CG automatic transmission mode, and the CG resources configured for the UE are NR-U CG resources, the CG resources or the HARQ process and / or MAC entity and / or cell group and / or HARQ process group and / or CG group of the CG resources do not support and / or are not configured with automatic retransmission (that is, the CG-retx timer is not configured); or, if the configured automatic transmission mode is the URLLC CG automatic transmission mode, and the CG resources for the UE are NR-U CG resources, then the CG resources or the HARQ process of the CG resources support / configure automatic transmission (that is, autonomousTX is configured).
[0329] As an example, if NR-U CG resources and URLLC CG resources are configured for the UE, for a CG resource or HARQ process, only one automatic transmission mode can be configured for it, that is, either the URLLC CG automatic transmission mode (that is, configuring autonomousTX) or the NR-U CG automatic retransmission mode (that is, configuring CG-retx timer).
[0330] Optionally, when different automatic transmission modes are configured for the HARQ process or CG resources or MAC entities or cell groups or HARQ process groups or CG groups of different CG resources, if the HARQ process or CG resources of the CG resources are NR-U CG resources, NR-U automatic retransmission can be configured (that is, CG-retx timer is configured, and autonomousTX is not configured); or, when different automatic transmission modes are configured for the HARQ process or CG resources of different CG resources, if the HARQ process or CG resources of the CG resources are NR-UCG resources, URLLC automatic transmission can be configured (that is, autonomousTX is configured, and CG-retx timer is not configured).
[0331] Optionally, when different automatic transmission modes are configured for the HARQ processes or CG resources of different CG resources, if the HARQ process or CG resources of the CG resources are URLLC CG resources, NR-U automatic retransmission can be configured (that is, CG-retxtimer is configured, and autonomousTX is not configured); or, when different automatic transmission modes are configured for the HARQ processes or CG resources of different CG resources, if the HARQ process or CG resources of the CG resources are URLLC CG resources, URLLC automatic transmission can be configured (that is, autonomousTX is configured, and CG-retx timer is not configured).
[0332] Second, the UE receives the CG configuration information sent by the network device, configures corresponding CG resources according to the CG configuration information, and uses the corresponding CG resources for automatic transmission and / or automatic retransmission.
[0333] Specifically, when supporting or configuring automatic retransmission, the UE first determines whether to use automatic transmission and the automatic transmission method to be used when using automatic transmission based on whether the CG configuration information carries automatic transmission parameters, or the received first indication information or pre-set configuration restriction conditions.
[0334] Optionally, if the automatic transmission restriction is for the UE, the UE adopts an automatic transmission mode for transmission.
[0335] If the automatic transmission is limited to a CG resource group or CG resource or HARQ process or MAC entity or cell group or HARQ process group, for different CG resource groups or CG resources or HARQ processes or MAC entities or cell groups or HARQ process groups, the UE adopts the corresponding automatic transmission method for transmission.
[0336] It can be understood that, based on the above embodiments, if for the same UE, when the simultaneous configuration of NR-UCG resources and URLLC CG resources is not supported, the same HARQ process and / or CG resources and / or UE and / or MAC entity and / or cell group and / or HARQ process group and / or CG group are restricted to not support multiple automatic transmission modes, or the same HARQ process and / or CG resources only support one automatic transmission mode.
[0337] In this possible design, the specific automatic transmission mode is independent of the CG resource configuration mode. That is, when only NR-UCG resources are configured, only CG retx timer can be configured, or only autonomousTX can be configured. Similarly, when only URLLCCG resources are configured, only CG retx timer can be configured, or only autonomousTX can be configured.
[0338] In an embodiment of the present application, a method for configuring or supporting automatic transmission mode when a UE supports NR-U CG resources and URLLC CG resources is provided. This solution limits the use of only one automatic transmission method or configuration, which ensures transmission reliability while avoiding the complexity of UE and network. Specific embodiment 2
[0340] In the NR-U system supporting URLLC services, when the network device configures NR-U CG resources and URLLC CG resources for the same UE at the same time, or configures CG resources according to the URLLC CG method and the NR-U CG method at the same time, if the same HARQ process and / or CG resources support multiple automatic transmission methods, the UE performs transmission behavior according to the first rule.
[0341] The specific implementation process is as follows:
[0342] First, the network device configures one CG resource or multiple CG resources at the same time for the UE.
[0343] 1. For a UE or a CG resource or a HARQ process or a MAC entity or a cell group or a HARQ process group or a CG group, the network device configures NR-U CG resources and URLLC CG resources at the same time.
[0344] 2. For a UE, when NR-U CG resources and URLLC CG resources are configured at the same time, or when CG resources are configured according to the URLLCCG mode and the NR-U CG mode at the same time, for the UE, multiple automatic transmission modes can be configured at the same time, but the UE is restricted to not configuring multiple automatic transmission modes for one CG resource and / or HARQ process and / or MAC entity and / or cell group and / or HARQ process group and / or CG group at the same time.
[0345] Optional, multiple automatic transmission modes include: URLLC CG automatic transmission mode (i.e. configuring autonomousTX), NR-U CG automatic retransmission mode (i.e. configuring CG-retx timer).
[0346] 3. For a UE, when NR-U CG resources and URLLC CG resources are configured at the same time, or, when CG resources are configured according to the URLLCCG method and the NR-U CG method at the same time, for the UE, for the same HARQ process or CG resource or MAC entity or cell group or HARQ process group or CG group, the UE is allowed to configure multiple automatic transmission modes at the same time.
[0347] Optionally, the multiple automatic transmission modes include: URLLC CG automatic transmission mode (ie, configuring autonomousTX), NR-U CG automatic retransmission mode (ie, configuring CG-retx timer). Optionally, the included automatic transmission mode may be an existing mode or an enhanced mode.
[0348] 4. The network device indicates the automatic transmission mode to be adopted through the first indication information.
[0349] Optionally, the first indication information may be indicated to the UE via broadcast / dedicated signaling (any one of RRC, MAC CE, and DCI).
[0350] Optionally, the first indication information can be notified to the UE when configuring CG resources.
[0351] Optionally, the first indication information may be an indication parameter per UE, an indication parameter per CG, an indication parameter per CG group, an indication parameter per HARQ process, a parameter per MAC, or a parameter per HARQ group. The embodiment of the present application does not limit the specific granularity of the rule.
[0352] Second, the UE receives the CG configuration information sent by the network device, configures corresponding CG resources according to the CG configuration information, and uses the corresponding CG resources for transmission and / or automatic retransmission.
[0353] Specifically, when automatic retransmission is supported or configured, the terminal device performs the following actions:
[0354] 1. The UE determines whether to use automatic transmission and the automatic transmission method to be used when using automatic transmission based on the CG configuration information, the first indication information, or the configuration restriction conditions.
[0355] 2. If the automatic transmission is limited to UE, for different CG resources or HARQ processes or MAC entities or cell groups or HARQ process groups or CG groups, the UE uses the corresponding automatic transmission mode for transmission. That is, for the UE, multiple automatic transmission modes can be configured at the same time, but the UE is restricted from configuring multiple automatic transmission modes for one CG resource and / or HARQ process at the same time.
[0356] 3. For a UE, when NR-U CG resources and URLLC CG resources are configured at the same time, or, when CG resources are configured according to the URLLCCG method and the NR-U CG method at the same time, for the UE, for the same HARQ process or CG resource or MAC entity or cell group or HARQ process group or CG group, the UE is allowed to configure multiple automatic transmission methods at the same time, and the UE performs one of the following actions: always performing automatic transmission according to one of the methods, or performing automatic transmission according to a combination of the two methods.
[0357] Exemplarily, always automatically transmitting in one of the ways may be any of the following:
[0358] 1) Transmit according to the URLLC CG automatic transmission mode;
[0359] 2) Transmit according to the NR-U CG automatic retransmission mode;
[0360] 3) According to the network instruction or pre-definition, determine whether to use the URLLC CG automatic transmission mode or the NR-U CG automatic retransmission mode, and transmit based on the determined automatic transmission mode;
[0361] 4) For a MAC PDU in a CG resource or HARQ process, if it fails to be transmitted or is not completed or successfully transmitted due to resource conflict, or the MAC PDU is a low priority MAC PDU, the URLLC CG automatic transmission mode is adopted;
[0362] Optionally, the resource is the resource corresponding to the first transmission of the MAC PDU.
[0363] 5) For a CG resource or a MAC PDU in a HARQ process, if the MAC PDU corresponding to the resource fails to be transmitted or is successfully transmitted due to LBT failure or receipt of an LBT failure indication, the NR-U CG automatic retransmission method is adopted; optionally, the resource is the resource corresponding to the first transmission of the MAC PDU.
[0364] Exemplary: Automatic transmission in combination of the two modes may be any of the following:
[0365] 1) According to the network instructions, determine to change the automatic transmission mode. That is, use different automatic transmission modes for transmission at different times;
[0366] 2) For a MAC PDU in a CG resource or HARQ process, if its first transmission fails or is not successfully transmitted or is not completed, a combination of URLLC CG automatic transmission and NR-U CG automatic retransmission is adopted.
[0367] 3) For a CG resource or a MAC PDU in a HARQ process, if it fails to be transmitted or is not completed or is not successfully transmitted due to resource conflict, or the MAC PDU is a low priority MAC PDU, the URLLC CG automatic transmission mode is adopted. Optionally, the resource is the resource corresponding to the first transmission of the MAC PDU.
[0368] If the MAC PDU fails to be transmitted or is not completed or is not successfully transmitted after M URLLC CG automatic transmissions, the NR-U CG automatic retransmission method can be adopted, or the URLLC CG automatic transmission and NR-U CG automatic retransmission method can be combined. Where M is a positive integer greater than 1.
[0369] 4) For a CG resource or a MAC PDU in a HARQ process, if the MAC PDU corresponding to the resource cannot be transmitted or successfully transmitted due to LBT failure or receipt of an LBT failure indication, the NR-U CG automatic retransmission method is adopted. Optionally, the resource is the resource corresponding to the first transmission of the MAC PDU.
[0370] If the MAC PDU is not transmitted or transmitted unsuccessfully after M NR-U CG automatic retransmissions, the URLLC CG automatic transmission method can be adopted, or a combination of URLLC CG automatic transmission and NR-U CG automatic retransmission can be adopted.
[0371] Optionally, in an embodiment of the present application, the terminal device may also limit the number of automatic transmissions.
[0372] Exemplary: limit the number of URLLC automatic transmissions; or limit the number of NR-U automatic retransmissions; or limit the total number of URLLC automatic transmissions and NR-U automatic retransmissions. For example: when limiting the total number of URLLC automatic transmissions and NR-U automatic retransmissions, if the above MAC PDU is not transmitted or is not successfully transmitted after N times (N>M) of automatic transmission, the automatic transmission is stopped, and N and M are both positive integers greater than 1.
[0373] Optionally, based on the above-mentioned specific embodiment 1 and specific embodiment 2, the above-mentioned rules can be per UE, per CG, per CG group, per HARQ process, per MAC, or per HARQ group. The embodiment of the present application does not limit the specific granularity of the rules. In addition, the present application may also include the following schemes:
[0374] 1) If the UE receives scheduling information from the network before the MAC PDU is automatically transmitted or automatically transmitted successfully, the UE transmits based on (follows) the scheduling indication information. The scheduling information of the network is dynamic scheduling information (new transmission / retransmission dynamic scheduling).
[0375] For example, when scheduling a new transmission or retransmission of dynamic grant resources (dynamic grant, DG), at least one of the following actions is performed on the HARQ process or the MAC PDU: stop automatic transmission (URLLC automatic transmission), stop CG retxtimer, stop CG timer. When the UE uses DG resources for transmission, the CG retx timer is not started. It can be understood that the above descriptions are all operations performed after the CG retx timer is started.
[0376] 2) If the UE receives scheduling information from the network before the MAC PDU is automatically transmitted or automatically transmitted successfully, the UE transmits based on the scheduling indication information. The scheduling information of the network may be a downlink feedback information DFI indication (A / N feedback).
[0377] For example, when the DFI indication is ACK, at least one of the following actions is performed on the HARQ process or the MAC PDU: stop automatic transmission (URLLC automatic transmission), stop CG retx timer, and stop CG timer. When the DFI indication is NACK, at least one of the following actions is performed on the HARQ process or the MAC PDU: do not stop automatic transmission (URLLC automatic transmission), stop CG retx timer, do not stop CG timer, and restart CG retx timer when using subsequent resources to continue retransmitting the HARQ process or the MAC PDU. It can be understood that the above implementation requires the addition of URLLC CG resources for the reception processing of DFI.
[0378] 3) When a new transmission or the first transmission is performed in the HARQ process or the CG MAC PDU, the CG retx timer is started. When the low priority resource is transmitted using the NR-U automatic retransmission mode, the CG retx timer is started to avoid the downlink indication not being received; or when the URLLC automatic transmission mode is used for transmission, the CG retx timer is started to avoid the downlink indication not being received.
[0379] Furthermore, when transmission is performed in accordance with the NR-U CG automatic retransmission mode, or when automatic transmission is performed in combination with the two modes, the CG retxtimer is started when the HARQ process or CG MAC PDU is newly transmitted or transmitted for the first time.
[0380] Optionally, the CG retx timer is started when at least one of the following conditions is met: there is a MAC PDU package with low priority resources, the MAC PDU has been packaged but not transmitted or not successfully transmitted or not completely transmitted, the MAC PDU is not transmitted or not successfully transmitted or not completely transmitted due to resource conflict, and the MAC PDU is a low priority MAC PDU. Furthermore, the CGtimer is started at the same time.
[0381] 4) For the above CG or HARQ process, if the corresponding HARQ entity obtains the MAC PDU to be transmitted, the HARQ process is set to pending state. Among them, low priority resources are transmitted using NR-U automatic retransmission mode.
[0382] Furthermore, when transmission is performed in accordance with the NR-U CG automatic retransmission method, or when automatic transmission is performed in combination with the two methods, for the above-mentioned CG resources or HARQ process, if the corresponding HARQ entity obtains the MAC PDU to be transmitted, the HARQ process is set to pending.
[0383] Exemplarily, when at least one of the following conditions is met, the HARQ process is set to pending: the MAC PDU has been packaged but not transmitted or not transmitted successfully or not transmitted incompletely, the MAC PDU has not been transmitted or not transmitted successfully or not transmitted incompletely due to resource conflict, the MAC PDU is a low priority MAC PDU, the MAC PDU is a MAC PDU that cannot be transmitted due to LBT failure, and the MAC PDU has not been transmitted due to receiving an LBT failure indication from the underlying layer.
[0384] Optionally, the MAC PDU is considered to be acquired when at least one of the following conditions is met: Wherein, the MAC PDU is not transmitted due to LBT failure, and can be transmitted in the URLLC automatic transmission mode.
[0385] Optionally, the condition is: the resource corresponding to the MAC PDU is a CG resource, the resource corresponding to the MAC PDU is a priority resource, the CG resource is configured for automatic transmission, the CG resource before the corresponding MAC PDU is low priority or pending or not transmitted or not transmitted successfully due to LBT failure, the HARQ process corresponding to the MAC PDU is pending, and the current resource size of the transmitted MAC PDU is the same as the MAC PDU size.
[0386] The technical solution of the embodiment of the present application is that when the terminal device is configured with URLLC CG resources and NR-U CG resources at the same time, and the terminal device supports one or more automatic transmission modes at the same time, the terminal device can determine the automatic transmission mode to be used, coordinate the use of NR-U CG resources and ULRRC CG resources, thereby ensuring information transmission between the terminal device and the network device.
