[0021] The present application is described below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily. It should also be noted that, for ease of description, only the parts related to the present application rather than all structures are shown in the accompanying drawings.

[0022] At present, the 5th Generation mobile communication technology (5G) is facing more and more demands. From the perspective of standard setting and technology development trends, the 5G system is committed to researching technical indicators such as higher speed (Gbps), massive links (1M / Km2), ultra-low latency (1ms), higher reliability, and 100-fold energy efficiency improvement to support new changes in demand.

[0023] In the first phase of 5G, slot aggregation based on dynamic scheduling (Dynamic Grant-Physical Uplink Shared channel, DG-PUSCH) and slot repetitions without scheduling (Configured Grant-Physical Uplink Shared channel, CG-PUSCH) are introduced to ensure coverage. Slot repetition means that the terminal uses multiple slots to repeatedly send transport blocks (Transport Block, TB), and TB has the same time domain resource allocation in each slot. In the second phase of 5G, in order to support the characteristics of ultra-high reliability and ultra-low latency transmission, and to complete the transmission of low-latency and high-reliability services in a shorter transmission time, it is necessary to enhance the uplink aggregation transmission based on dynamic scheduling and the uplink repetition transmission without scheduling, so the same TB (transport block) is repeatedly sent once or more than once in the same slot, or the same TB is repeatedly sent across the slot boundary in multiple consecutive available slots.

[0024] With the arrival of CG-PUSCH service, the standard stipulates that the first transmission time domain position of CG-PUSCH is the first transmission occasion (TO) or the TO corresponding to the redundancy version (RV) index 0. When the time domain position of the arrival of CG-PUSCH service misses the first TO or the TO corresponding to RV0, in one implementation scenario, the transmission of CG-PUSCH can be delayed to the first TO of the next cycle or to the TO corresponding to RV0 of the current cycle or the next cycle.

[0025] In addition, in some embodiments, when the network side receives the TB of CG-PUSCH, it can trigger the DG-PUSCH by sending the downlink control information (DCI) encrypted by the non-scheduled radio network identifier (Configured Scheduling-Radio Network Temporary Identifier, CS-RNTI) to indicate the reception of the wrong negative acknowledgment (NACK). If the TB of the triggered retransmission DG-PUSCH is not received within the configured time window (ConfigGrantTimer), it indicates the reception of the correct confirmation acknowledgment (ACK).

[0026] The embodiment of the present application targets the case where resources are configured for the CG-PUSCH physical channel. Reference resource information is input into a setting function module, and the operation results of the setting function module are used to configure the resources of the physical channel, thereby effectively reducing the CG-PUSCH transmission delay and improving the accuracy of the CG-PUSCH transmission.

[0027] Figure 1 The flowchart of a resource configuration method provided by an embodiment is applicable to a first communication node, where the first communication node mainly refers to a network side node, such as a base station or an access point (AP). Figure 1 As shown, the method provided in this embodiment includes step 110, step 120 and step 130.

[0028] In step 110, a reference resource information set of a physical channel is received.

[0029] In step 120, the reference resource information set is input into a setting function module to obtain the operation result of the setting function module.

[0030] In step 130, resources of the physical channel are configured according to the operation result.

[0031] In this embodiment, a reference resource information set of a physical channel is first received, and the physical channel may be a scheduling-free physical uplink shared channel. The received reference resource information set is input as an input parameter to a setting function module, and the operation result of the setting function module is generated, and the resources of the physical channel are configured according to the operation result of the setting function module. Among them, the setting function module may be a module that uses any algorithm to realize the inference of the optimal information of the resource configuration of the physical channel, such as using a machine learning algorithm or a neural network, etc., to infer the location of the transmission opportunity, the size of the repeated transmission block, the resource pool corresponding to the service type of the terminal side service, and / or the time-frequency domain resources. For example, the setting function module is an artificial intelligence (AI) model. As a computer program constructed by machine learning and deep learning technologies, the AI ​​model can be trained with a large amount of sample data (including a known reference resource information set and the corresponding optimal information of resource configuration), and can be used to automatically learn and extract features from the input data, analyze, infer and predict according to the learned knowledge, so that in actual applications, the actual reference resource information set is input to the AI ​​model to automatically output the operation result, and the operation result can be used as the basis for configuring the resources of the physical channel. Since the setting function module has the ability to predict the optimal resource information of the reference resource information set, the resource configuration method can effectively reduce the physical channel transmission delay and improve the correctness of the physical channel transmission.

[0032] In one embodiment, the reference resource information set includes at least one of the following: arrival time, data packet size, and service performance requirements of the terminal side service. Arrival time, data packet size, service performance requirements, and frame structure of the terminal side service; service type of the terminal side service; arrival time and period of the terminal side service in a future period of time associated with the current transmission service; frame structure, idle resources, and service transmission status reported by the terminal; time-frequency domain resource information; semi-static frame structure and non-transmittable symbol pattern; semi-static frame structure and channel monitoring information.

[0034] In one embodiment, the time domain length of the nominal repetitive transmission block is determined according to a Time Domain Resource Allocation (TDRA) table.

[0035] In one embodiment, the time domain length of the actual repeated transmission block is determined according to the time domain length of the actual transmission.

[0036] In one embodiment, a single nominal repetition transmission block is composed of several actual repetition transmission blocks.

[0037] In one embodiment, the method further comprises:

[0038] In case of a physical channel reception error, the setting function module is reactivated, and the operation result is updated according to the updated reference resource information set through the setting function module.

[0039] In one embodiment, the method further comprises:

[0040] In case of a physical channel reception error, the first transmission time domain position configured by the system is determined as the first transmission opportunity or the transmission opportunity corresponding to 0;

[0041] Sending CS-RNTI-scrambled DCI triggers physical uplink shared channel transmission DG-PUSCH based on dynamic scheduling.

[0042] In one embodiment, when the operation result includes the position of the first transmission opportunity and the first transmission opportunity is determined to be RV0, the time domain position of the multiple repeated transmission physical channels is determined according to the number of repetitions indicated by the Radio Resource Control (RRC) signaling or the TDRA table.

[0043] Figure 2 The flowchart of a transmission method provided in an embodiment is applicable to a second communication node, where the second communication node mainly refers to a terminal side node, such as a user equipment (UE). Figure 2 As shown, the method provided in this embodiment includes the following steps:

[0044] In step 210, a reference resource information set of a physical channel is sent.

[0045] In step 220, the reference resource information set is input into a setting function module to obtain the operation result of the setting function module.

[0046] In step 230, a physical channel is transmitted according to the operation result.

[0047] This embodiment sends a reference resource information set of a physical channel, inputs the reference resource information set into a setting function module, obtains an operation result of the setting function module, and transmits the physical channel according to the operation result, thereby effectively reducing the transmission delay of the physical channel and improving the correctness of the physical channel transmission.

[0048] In one embodiment, the reference resource information set includes at least one of the following: arrival time, data packet size, and service performance requirements of the terminal side service. Arrival time, data packet size, service performance requirements, and frame structure of the terminal side service; service type of the terminal side service; arrival time and period of the terminal side service in a future period of time associated with the current transmission service; frame structure, idle resources, and service transmission status reported by the terminal; time-frequency domain resource information; semi-static frame structure and non-transmittable symbol pattern; semi-static frame structure and channel monitoring information.

[0049] In one embodiment, the operation result includes at least one of the following: the location of the first transmission opportunity and the first transmission opportunity is determined to be RV0; resource information corresponding to the service type of the terminal side service; resource information of the terminal side service and idle resource information allocated to other service channels when the terminal side service is not transmitted; resource information corresponding to the terminal side service in a future period of time associated with the current transmission service; resource pool corresponding to the service type of the terminal side service; time-frequency domain resources of the terminal side service; the size of the nominal repeated transmission block and the size of the actual repeated transmission block; enabling additional transmission opportunities, the additional transmission opportunities including N transmission opportunities added on the basis of the configured repeated transmission opportunities, N is an integer greater than 0.

[0050] In one embodiment, the method further comprises:

[0051] In case of a physical channel reception error, the setting function module is reactivated, and the operation result is updated according to the updated reference resource information set through the setting function module.

[0052] In one embodiment, the method further comprises:

[0053] In case of a physical channel reception error, the first transmission time domain position configured by the system is determined as the first transmission opportunity or the transmission opportunity corresponding to redundancy version 0;

[0054] In case of receiving downlink control information DCI scrambled by the scheduling-free radio network identifier CS-RNTI, a physical uplink shared channel DG-PUSCH based on dynamic scheduling is transmitted.

[0055] In one embodiment, when the operation result includes the position of the first transmission opportunity and the first transmission opportunity is determined to be RV0, the time domain position of the multiple repeated transmission physical channels is determined according to the number of repetitions indicated by the RRC signaling or the TDRA table.

[0056] The resource configuration method and transmission method of the present application are exemplarily described below through some embodiments.

[0057] In the current CG-PUSCH technology of mobile communication systems, the standard stipulates that the first transmission time domain position of CG-PUSCH is on the first TO or on the TO corresponding to RV index 0, which will cause the arrival of services to be not completely aligned with the TO, resulting in additional delays. The HARQ mechanism of CG-PUSCH feedback on the network side will also lead to increased DCI overhead or multiple invalid repetitions of CG-PUSCH.

[0058] Figure 3 FIG. 1 is a schematic diagram of a delay time when three TOs appear in an embodiment. Figure 3 As shown in the figure, in the current mobile communication system standard, the network side configures the time domain resource location for scheduling-free transmission by configuring one or more TOs for repeated transmission in each cycle, and configuring the corresponding RV pattern. When the CG-PUSCH arrives after the first TO of the first cycle, if the first TO is missed or the TO with RV=0, the transmission can only be postponed to the first TO of the next cycle. Figure 3 As shown, it brings a delay time of 3 TOs.

[0059] To this end, the network side and the terminal side of this embodiment can use the setting function module to predict the optimal resources at multiple times.

[0060] Embodiment 1

[0061] This embodiment takes the network side as an example and proposes a method for setting the operation of a functional module (such as an AI model) according to a received reference resource set to generate an operation result.

[0062] The reference resource set may be at least one of the following:

[0063] Method 1: The reference resource set is the arrival time and data packet size of the terminal-side service and the service performance requirements. The deployed AI model takes the reference resource set as an input parameter, and determines the position of the first TO and judges it as RV0 based on the training and prediction of the AI ​​model. According to the number of repetitions indicated by the RRC signaling or the TDRA table (Time Domain Resource Allocation), multiple time domain positions of multiple repetitions are determined.

[0064] Method 2: The reference resource set is the arrival time of the terminal-side service, the data packet size, the service performance requirements, and the frame structure of the system configuration. The deployed AI model takes the reference resource set as an input parameter, and outputs the resource information of the terminal-side service based on the training and prediction of the AI ​​model. When the service is not transmitted, the idle part of the resource information is allocated to other service channels.

[0065] Method 3: The reference resource set is the service type to be transmitted. The deployed AI model takes the transmission service type as an input parameter and outputs the resource information corresponding to the service type (including time domain, frequency domain and / or spatial domain) based on the training and prediction of the AI ​​model. The network-side functional module has already trained multiple sets of resource information for different service types in advance.

[0066] Method 4: The reference resource set is the arrival time and period of the services to be transmitted in the future carried by the current transmission service. The deployed AI model takes the arrival time and period of the services to be transmitted in the future as input parameters, and outputs the resource information corresponding to the period of time (including time domain, frequency domain and / or spatial domain) based on the training and prediction of the AI ​​model.

[0067] Method 5: The reference resource set is the frame structure, idle resources and transmission conditions reported by other terminals. The deployed AI model uses the reference resource set as an input parameter, and outputs different resource pools based on the AI ​​model training, monitoring and prediction on the network side. For services with poor channels and large interference impact, resource pool 1 is allocated; for services with good channels and small interference impact, resource pool 2 is allocated. The network side does not need to feedback HARQ information.

[0068] Method 6: The reference resource set is the time-frequency domain resources configured by the system. The deployed AI model uses the reference resource set as an input parameter, and outputs the time-frequency domain resources for the corresponding service transmission based on the AI ​​model training, monitoring and prediction on the network side. This means that the functional module decides by itself which resources the service should use.

[0069] Fallback mechanism: The network side outputs resource information based on the above method. Once the network side finds that it always receives errors, the fallback mechanism can be at least one of the following:

[0070] Method 1: Reactivate the functional module and update the operation result of the functional module according to the updated reference resource set.

[0071] Method 2: Falling back to a mode without functional modules, that is, falling back to traditional mobile communication transmission technology, including but not limited to: in the case of CG-PUSCH physical channel reception error, determining the first transmission time domain position configured by the system as the first transmission opportunity or the transmission opportunity corresponding to RV0; when receiving CS-RNTI encrypted DCI, transmitting DG-PUSCH.

[0072] For the terminal side, a setting function module (such as an AI model) can also be deployed, and the reference resource information set can be input into the setting function module to obtain the operation result, and the physical channel (such as CG-PUSCH) can be transmitted according to the operation result. Among them, the reference resource information set, the operation result and the fallback mechanism can refer to the description on the network side. In addition, when the operation result includes the position of the first transmission opportunity and the first transmission opportunity is determined to be RV0, the time domain position of the multiple repeated transmission physical channels can be determined according to the number of repetitions indicated by the RRC signaling or the TDRA table.

[0073] Embodiment 2

[0074] This embodiment takes the terminal side as an example and proposes a method for setting the operation of a functional module (such as an AI model) according to a received reference resource set to generate the operation result of the functional module.

[0075] The reference resource set may be at least one of the following:

[0076] Method 1: The reference resource set is the arrival time and data packet size of the terminal-side service and the service performance requirements. The deployed AI model takes the reference resource set as an input parameter, and determines the position of the first TO and judges it as RV0 based on the training and prediction of the AI ​​model. According to the number of repetitions indicated by the RRC signaling or the TDRA table (Time Domain Resource Allocation), multiple time domain positions of multiple repetitions are determined.

[0077] Method 2: The reference resource set is the arrival time of the terminal-side service, the data packet size, the service performance requirements and the frame structure of the system configuration. The deployed AI model takes the reference resource set as an input parameter, and outputs the resource information of the terminal-side service according to the training and prediction of the AI ​​model, and when the service is not transmitted, the idle part of the resource information is allocated to other service channels.

[0078] Method 3: The reference resource set is the service type to be transmitted. The deployed AI model takes the transmission service type as an input parameter and outputs the resource information corresponding to the service type (including time domain, frequency domain and / or spatial domain) based on the training and prediction of the AI ​​model. The terminal side functional module has already trained multiple sets of resource information for different service types in advance.

[0079] Method 4: The reference resource set is the arrival time and period of the services to be transmitted in the future carried by the current transmission service. The deployed AI model takes the arrival time and period of the services to be transmitted in the future as input parameters, and outputs the resource information corresponding to the period of time (including time domain, frequency domain and / or spatial domain) based on the training and prediction of the AI ​​model.

[0080] Method 5: The reference resource set is the frame structure, idle resources and transmission conditions reported by other terminals. The deployed AI model uses the reference resource set as an input parameter, and outputs different resource pools based on the AI ​​model training, monitoring and prediction on the terminal side. For services with poor channels and large interference impact, resource pool 1 is allocated; for services with good channels and small interference impact, resource pool 2 is allocated. The terminal side does not need to feedback HARQ information.

[0081] Method 6: The reference resource set is the time-frequency domain resources configured by the system. The deployed AI model uses the reference resource set as an input parameter, and outputs the time-frequency domain resources for the corresponding service transmission based on the AI ​​model training, monitoring and prediction on the terminal side. This means that the functional module decides by itself which resources the service should use.

[0082] Fallback mechanism: The terminal side outputs resource information based on the above method. Once the terminal side finds that it always receives errors, the fallback mechanism can be at least one of the following:

[0083] Method 1: Reactivate the functional module and update the operation result of the functional module according to the updated reference resource set.

[0084] Method 2: Fall back to a mode without functional modules, that is, fall back to traditional mobile communication transmission technology.

[0085] For the terminal side, a setting function module (such as an AI model) can also be deployed, and the reference resource information set can be input into the setting function module to obtain the operation result, and the physical channel (such as CG-PUSCH) can be transmitted according to the operation result. Among them, the reference resource information set, the operation result and the fallback mechanism can refer to the description on the network side. In addition, when the operation result includes the position of the first transmission opportunity and the first transmission opportunity is determined to be RV0, the time domain position of the multiple repeated transmission physical channels can be determined according to the number of repetitions indicated by the RRC signaling or the TDRA table.

[0086] Embodiment 3

[0087] This embodiment takes the network side as an example and proposes a method for setting the operation of a functional module (such as an AI model) according to a received reference resource set to generate the operation result of the functional module.

[0088] In the current mobile communication system, for CG-PUSCH repetition type B transmission, it is stipulated that when a nominal TB transmission encounters a time slot boundary and a non-transmittable symbol, multiple actual TB blocks will be generated. Among them, the nominal TB is determined based on the time and frequency domain resources notified by the base station, but the actual TB will increase the actual coding rate due to the reduction of time domain resources, resulting in reception errors at the receiving end.

[0089] Figure 4 An embodiment provides a schematic diagram of nominal repetition and actual repetition. Figure 4As shown in the figure, nominal repetition #2 is divided into actual repetition #2 and actual repetition #3 because of the time slot boundary and non-transmittable symbols, and nominal repetition #4 is divided into actual repetition #5 and actual repetition #6 because of the time slot boundary. Then the nominal TB determines the data size of the transport block based on the 6 symbol lengths of the nominal repetition, while the actual repetition #2, #3, #5 and #6 have to continuously increase the actual coding bit rate to transmit the same data size of the transport block because of the reduced time domain resources, which leads to reception errors at the receiving end.

[0090] The reference resource set is a semi-static frame structure and a non-transmittable symbol pattern. The deployed AI model takes the reference resource set as an input parameter. According to the training and prediction of the AI ​​model, the operation result of the functional module is the size of the nominal repeated TB and the size of the actual repeated TB.

[0091] Furthermore, the time domain length of the nominal repeated TB is notified according to the TDRA, and the time domain length of the actual repeated TB is determined according to the time domain length of the actual transmission.

[0092] Furthermore, several actual repeated TBs are combined into one nominal repeated TB. Figure 4 As shown, actual repetition #2 is the first half of the nominal repetition, and actual repetition #3 is the second half of the nominal repetition.

[0093] Fallback mechanism: The network side outputs resource information based on the above method. Once the network side finds that it always receives errors, the fallback mechanism can be at least one of the following:

[0094] Method 1: Reactivate the functional module and update the operation result of the functional module according to the updated reference resource set.

[0095] Method 2: Fall back to a mode without functional modules, that is, fall back to traditional mobile communication transmission technology.

[0096] For the terminal side, a setting function module (such as an AI model) can also be deployed, and the reference resource information set can be input into the setting function module to obtain the operation result, and the physical channel (such as CG-PUSCH) can be transmitted according to the operation result. Among them, the reference resource information set, the operation result and the fallback mechanism can refer to the description on the network side. In addition, when the operation result includes the position of the first transmission opportunity and the first transmission opportunity is determined to be RV0, the time domain position of the multiple repeated transmission physical channels can be determined according to the number of repetitions indicated by the RRC signaling or the TDRA table.

[0097] Embodiment 4

[0098] This embodiment takes the terminal side as an example and proposes a method for setting the operation of a functional module (such as an AI model) according to a received reference resource set to generate the operation result of the functional module.

[0099] The reference resource set is a semi-static frame structure and a non-transmittable symbol pattern. The deployed AI model takes the reference resource set as an input parameter. According to the training and prediction of the AI ​​model, the operation result of the functional module is the size of the nominal repeated TB and the size of the actual repeated TB.

[0100] Furthermore, the time domain length of the nominal repeated TB is notified according to the TDRA, and the time domain length of the actual repeated TB is determined according to the time domain length of the actual transmission.

[0101] Furthermore, several actual repeated TBs are combined into one nominal repeated TB. Figure 4 As shown, actual repetition #2 is the first half of the nominal repetition, and actual repetition #3 is the second half of the nominal repetition.

[0102] Fallback mechanism: The terminal side outputs resource information based on the above method. Once the terminal side finds that it always receives errors, the fallback mechanism can be at least one of the following:

[0103] Method 1: Reactivate the functional module and update the operation result of the functional module according to the updated reference resource set.

[0104] Method 2: Fall back to a mode without functional modules, that is, fall back to traditional mobile communication transmission technology.

[0105] For the terminal side, a setting function module (such as an AI model) can also be deployed, and the reference resource information set can be input into the setting function module to obtain the operation result, and the physical channel (such as CG-PUSCH) can be transmitted according to the operation result. Among them, the reference resource information set, the operation result and the fallback mechanism can refer to the description on the network side. In addition, when the operation result includes the position of the first transmission opportunity and the first transmission opportunity is determined to be RV0, the time domain position of the multiple repeated transmission physical channels can be determined according to the number of repetitions indicated by the RRC signaling or the TDRA table.

[0106] Embodiment 5

[0107] In the current mobile communication system standard, for CG-PUSCH repetition type B transmission, when uplink control information (UCI) is multiplexed on the PUSCH of repetition type B, UCI is only multiplexed on the first actual repetition of a time domain symbol greater than 1 symbol. And the time-frequency domain resources occupied by UCI are calculated by taking the minimum value of the nominal repetition time domain resources and the actual repetition time domain resources, and the actual repetition time domain resources cannot be less than the number of resources required by the number of coded modulation symbols determined by UCI.

[0108] Doing so ensures that the UCI encoding rate is reasonable and that UCI information is not lost, but it will affect the sending of actual repetitions. Once all the resources of the actual repetitions are used for UCI sending, the actual repetitions cannot be sent.

[0109] This embodiment takes the network side as an example and proposes a method for setting the operation of a functional module (such as an AI model) according to a received reference resource set to generate the operation result of the functional module.

[0110] The reference resource set is a semi-static frame structure and other channel monitoring. The deployed AI model uses the reference resource set as an input parameter. According to the training and prediction of the AI ​​model, it accurately obtains which actual transmissions will be discarded or misinterpreted. The operation result of the functional module is to enable additional TO, thereby ensuring the number of repeated transmissions. The additional TO means adding N TOs based on the configured number of repeated TOs, where N is an integer greater than 0. Then the repeated transmission TB will continue to be transmitted on the additional TO.

[0111] Fallback mechanism: The network side outputs resource information based on the above method. Once the network side finds that it always receives errors, the fallback mechanism can be at least one of the following:

[0112] Method 1: Reactivate the functional module and update the operation result of the functional module according to the updated reference resource set.

[0113] Method 2: Fall back to a mode without functional modules, that is, fall back to traditional mobile communication transmission technology.

[0114] For the terminal side, a setting function module (such as an AI model) can also be deployed, and the reference resource information set can be input into the setting function module to obtain the operation result, and the physical channel (such as CG-PUSCH) can be transmitted according to the operation result. Among them, the reference resource information set, the operation result and the fallback mechanism can refer to the description on the network side. In addition, when the operation result includes the position of the first transmission opportunity and the first transmission opportunity is determined to be RV0, the time domain position of the multiple repeated transmission physical channels can be determined according to the number of repetitions indicated by the RRC signaling or the TDRA table.
