The network architecture and service scenarios described in the embodiments of the present application are for the purpose of illustrating the technical solutions of the embodiments of the present application more clearly, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. The evolution of new business scenarios and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

Please refer to FIG. 1 , which shows a schematic diagram of a network architecture of a communication system provided by an embodiment of the present application. The network architecture may include: terminal 10 and base station 20 .

The number of terminals 10 is usually multiple, and one or more terminals 10 may be distributed in a cell managed by each base station 20 . The terminal 10 may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to the wireless modem with wireless communication functions, as well as various forms of user equipment (User Equipment, UE), mobile stations ( Mobile Station, MS), terminal device, etc. For convenience of description, in the embodiments of the present application, the devices mentioned above are collectively referred to as terminals.

The base station 20 is a device deployed in the access network to provide the terminal 20 with a wireless communication function. The base station 20 may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems using different radio access technologies, the names of devices with base station functions may be different, for example, in the 5th generation (5th-Generation, 5G) NR system, they are called gNodeBs or gNBs. As communication technology evolves, the name "base station" may change. For convenience of description, in the embodiments of the present application, the above-mentioned apparatuses for providing wireless communication functions for the terminal 20 are collectively referred to as base stations.

Optionally, what is not shown in FIG. 1 is that the above-mentioned network architecture also includes other network devices, such as: a central control node (Central Network Control, CNC), an access and mobility management function (Access and Mobility Management Function, AMF) ) device, session management function (Session Management Function, SMF) or user plane function (User Plane Function, UPF) device, etc.

The "5G NR system" in the embodiments of the present disclosure may also be referred to as a 5G system or an NR system, but those skilled in the art can understand its meaning. The technical solutions described in the embodiments of the present disclosure may be applicable to the 5G NR system, and may also be applicable to the subsequent evolution system of the 5G NR system.

For ease of understanding, some related terms involved in this application are introduced below:

1) Ultra-reliable and Low Latency Communications (Ultra-reliable and Low Latency Communications, URLLC)

URLLC needs to support the transmission of services such as Factory Automation, Transport Industry, and Electrical Power Distribution in the 5G system. In order to support the transmission of URLLC services, the 5G standard enhances the Configuration Grant (CG), that is, it introduces multiple CG configurations, as well as the specific configuration and use of CG (such as supporting slot-level period, supporting CG automatic transfer, etc.) have been enhanced.

Considering the requirement to support URLLC services in interference-controlled NR-U scenarios, the following enhancements can be made:

a. How to use NRU CG and URLLC CG enhancement in NR-U scenarios;

b. UE-initial channel occupancy time (Channel Occupancy Time, COT) for FBE.

2) CG enhancement in URLLC

To support the high latency requirements of URLLC services, URLLC enhances the CG cycle to support any slot-level service cycle.

In order to support multiple URLLC services and high latency requirements of URLLC services, URLLC also introduces the concept of multiple CGs. In addition, the HARQ processes configured by different CGs are different, and harq-ProcID-Offset2 ensures that the processes of different CGs are also different.

Due to the conflict between CG resources and other resources, in order to ensure that the media access control layer protocol data unit (Media Access Control Protocol Data Unit, MAC PDU) (that is, Deprioritized MAC PDU) that has been packaged in the CG resource is not discarded, or, To ensure that the Deprioritized MAC PDU is transmitted as soon as possible, automatic transmission for CG is introduced. That is to say, for the CG corresponding to the grouped MAC PDU that cannot be transmitted due to resource conflict, the CG resource in the same CG configuration in the subsequent same HARQ process can be used for new transmission. For example, the use of automatic transmission is determined by autonomousTx.

If the physical layer has different priorities and there is a conflict between CG and CG, the MAC can indicate one or more MAC PDUs to the physical layer. Similarly, if there is a conflict between service data (data) and uplink scheduling request (Scheduling Request, SR), the MAC can also indicate the SR and the MAC PDU to the physical layer.

3) NR-U

NR works in unlicensed frequency bands, including the following working scenarios:

Scenario A: Carrier aggregation scenario, the primary cell (Primary Cell, PCell) is the licensed spectrum, and the secondary cells (Secondary Cell, SCell) working on the unlicensed spectrum are aggregated through carrier aggregation;

Scenario B: Dual-connection working scenario, PCell is Long Term Evolution (Long Term Evolution, LTE) licensed spectrum, PScell is NR unlicensed spectrum;

Scenario C: Independent working scenario, NR works as an independent cell in unlicensed spectrum;

Scenario D: NR single-cell scenario, the uplink (Up Link, UL) works in the licensed spectrum, and the downlink (Down Link, DL) works in the unlicensed spectrum;

Scenario E: Dual-connection working scenario, PCell is NR licensed spectrum, PScell is NR unlicensed spectrum.

Generally speaking, the working frequency band (Band) of NR-U is 5GHz unlicensed spectrum and 6GHz unlicensed spectrum. On unlicensed spectrum, the design of NR-U should ensure fairness with other systems already working on these unlicensed spectrum, such as Wireless Fidelity (Wi-Fi). The principle of fairness is that NR-U cannot affect systems already deployed on unlicensed spectrum (such as Wi-Fi) more than between those systems.

To ensure fair coexistence among systems on unlicensed spectrum, energy detection has been identified as a basic coexistence mechanism. The general energy detection mechanism is the Listen Before Talk (LBT) mechanism. The basic principle of this mechanism is: before the base station or terminal (transmitter) transmits data on the unlicensed spectrum, it needs to listen for a period of time according to regulations. . If the result of listening indicates that the channel is in an idle state, the transmitting end can transmit data to the receiving end. If the listening result indicates that the channel is in an occupied state, the transmitting end needs to roll back for a period of time and continue to listen to the channel according to the regulations. Only when the channel listening result is in an idle state can data be transmitted to the receiving end.

There are currently four channel access mechanisms (category) defined in NR-U:

Category 1: Direct Transfer Mechanism

This mechanism is used for the sender (TX side) to transmit quickly after the switching gap in the COT;

Switching gap refers to the conversion time when the transmission is received, and the typical value is not more than 16us.

Category 2: LBT mechanism that does not require random back-off

This mechanism means that the time for the UE to listen to the channel is determined, which is generally relatively short, such as 25us.

Category 3: LBT mechanism with random back-off (fixed competition window)

In the LBT process, the transmitting side randomly selects a random value in the contention window to determine the time to listen to the channel.

Category 4: LBT mechanism with random back-off (the competition window is not fixed)

In the LBT process, the transmitting side randomly selects a random value in the contention window to determine the time to listen to the channel, and the contention window is variable.

Due to the restraint of the above content, for the terminal, the base station needs to transmit data to the terminal within the maximum channel occupation time (Max COT, MCOT); if the base station does not preempt the channel, that is, outside the MCOT time, the terminal will not receive the data. To the scheduling data of the base station to the terminal.

4) Uplink LBT failure in NR-U

The uplink transmission initiated by the UE mainly includes the following categories:

SR: used to request uplink resources;

Physical Random Access Channel (PRACH): triggered by RACH, the UE needs to send msg1;

Physical Uplink Shared Channel (PUSCH): including configured grant-based uplink data transmission and dynamic grant-based uplink data transmission;

Physical layer signaling transmission: including acknowledgement ACK/non-acknowledgement NACK feedback, channel state information (Channel State Information, CSI) reporting, etc.

On the unlicensed frequency band, the UE needs to use LBT to monitor whether the channel is available before transmitting SR, PRACH or PUSCH. If it is not available, that is, the LBT fails, the UE needs to wait until the next transmission opportunity to perform LBT again. If LBT failure is detected, the MAC layer needs to be notified of LBT failure information.

In R16, it is considered that only one resource that needs to be transmitted is indicated from the MAC layer to the physical layer.

For R16NR-U, the scenario of resource conflict is not considered. In R16NR-U, the physical layer will only receive a resource that needs to be transmitted from a higher layer. Therefore, there is no regulation on how to do LBT detection. In R17, in order to support the preferential transmission of high-priority resources (such as the preferential transmission of resources corresponding to URLLC services), the upper layer may indicate to the physical layer multiple resources that can be transmitted, such as multiple MAC PDUs, or MAC PDU+SR, etc. , at this time, it is necessary to consider how to perform LBT detection and data transmission.

However, subsequent embodiments of the present application propose a solution for data transmission under the condition that the upper layer MAC indicates to the physical layer uplink transmission resources on multiple unlicensed frequency bands.

Hereinafter, the technical solutions of the present application will be described with reference to several exemplary embodiments.

Both the detection process and the data transmission process are controlled. Subsequent embodiments of the present application will introduce different control modes respectively.

Please refer to FIG. 3 , which shows a flowchart of an uplink transmission control method provided by an embodiment of the present application. The method may be executed interactively by a terminal and a network-side device, wherein the terminal may correspond to the network architecture shown in FIG. 1 . The terminal in the communication system, the network side device may be a base station in the communication system corresponding to the network architecture shown in FIG. 1 . The method may include the following steps:

Step 301, the network side device sends configuration information or scheduling information to the terminal; correspondingly, the terminal receives the configuration information or scheduling information sent by the network side device.

Wherein, the configuration information or scheduling information is used to indicate at least two uplink transmission resources.

In this embodiment of the present application, the at least two uplink transmission resources are resources on an unlicensed frequency band, and there is conflict or overlap between the at least two uplink transmission resources.

In a possible implementation manner, the configuration information or scheduling information is further used to configure or indicate the priorities of the at least two uplink transmission resources.

In a possible implementation manner, the network side device further sends detection mode indication information to the terminal, where the detection mode indication information is used to indicate the idle state detection mode; correspondingly, the terminal receives the detection mode indication information.

In this embodiment of the present application, the network side device may configure at least one idle state detection method for the terminal, or at least one idle state detection method may be preset in the terminal; the terminal may determine by itself which idle state detection method to use, Alternatively, the terminal may also use one detection method among multiple idle state detection methods according to the instruction of the network side device.

Alternatively, the terminal may also determine the idle state detection method to be used according to the instruction of the network side device. For example, the network side device directly indicates the idle state detection method used by the terminal to the terminal, and the terminal performs subsequent idle state detection in the manner indicated by the network side device.

Wherein, the idle state detection method includes:

Select at least one resource of a specified category from the at least two uplink transmission resources for detection; for example, the terminal detects a certain type of resources (such as PRACH resources) among them; for another example, the network side device may instruct the terminal to detect the resources belonging to a certain category among them. Type a class of resources (such as PRACH resources) for detection;

or,

One resource is selected for detection from the at least two uplink transmission resources; for example, the terminal detects the one resource with the highest priority and/or the smallest resource index among them. For another example, the network-side device may instruct the terminal to detect a resource with the highest priority and/or the smallest resource index;

or,

Select a specified number of resources from the at least two uplink transmission resources for detection; for example, the network side device may instruct the terminal to detect the three resources with the highest priority or the smallest resource index; The 3 resources with the smallest index are detected; for another example, the terminal detects 3 of the resources;

or,

The at least two uplink transmission resources are detected respectively; for example, the terminal determines by itself or detects the at least two uplink transmission resources in a predefined manner; for another example, the network side device may instruct the terminal to detect the at least two uplink transmission resources. test separately.

In a possible implementation manner, the above-mentioned uplink transmission resources include:

Dynamically grant DG resources, configure grant CG resources, physical uplink control channel PUCCH resources, or physical random access channel PRACH resources.

In this embodiment of the present application, the network side device may configure resources or schedule resource transmission for the terminal, where the configuration information or scheduling information may indicate the following:

1) The configured/scheduled resources can be DG resources, CG resources, PUCCH resources, PRACH resources, etc.;

2) While configuring/scheduling resources, configure or indicate priority information for the configured/scheduled resources;

Wherein, the priority information of the indication may include a high priority indication and a low priority indication;

Alternatively, the priority information may include more levels of priority indications, such as at least three levels of priority indications.

Optionally, the priority indication may be a physical layer priority indication or a logical channel priority indication.

In a possible implementation manner, when priorities of at least two uplink transmission resources are statically configured in the terminal (for example, pre-configured by a communication standard), the terminal may acquire the statically configured priorities of the at least two uplink transmission resources .

In another possible implementation manner, the terminal may acquire the priorities of the at least two uplink transmission resources according to the priorities of the logical channels of the at least two uplink transmission resources.

For example, the terminal takes the priority of the logical channel of the at least two uplink transmission resources as the priority of the at least two uplink transmission resources. For another example, the terminal takes the information carried by the at least two uplink transmission resources or the priority of the logical channel of the data to be transmitted as the priority of the at least two uplink transmission resources.

3) Indicate the LBT detection mode, such as which type of resources (eg, high-priority resources) are only detected or all resources are detected.

Wherein, when the idle state detection method indicated by the detection mode indication information is to select at least one designated category/one/designated number of resources from the at least two uplink transmission resources for detection, the terminal performs uplink data transmission on the unlicensed channel The control process can refer to the following steps.

Step 302, the terminal acquires at least two uplink transmission resources.

In this embodiment of the present application, a higher layer (such as the MAC layer) in the terminal may indicate the above at least two uplink transmission resources to the physical layer. For example, in the URLLC transmission scenario, the MAC layer may indicate multiple CG resources to the physical layer, or The CG resource and other resources are indicated to the physical layer at the same time.

In other embodiments of the present application, a higher layer (such as the MAC layer) in the terminal may indicate to the physical layer the information to be transmitted corresponding to the at least two uplink transmission resources. For example, in the URLLC transmission scenario, the MAC layer may indicate to the physical layer The physical layer indicates the MAC PDUs corresponding to multiple CG resources, or simultaneously indicates to the physical layer the MAC PDUs corresponding to the CG resources and the information to be transmitted (such as SR, MAC PDUs, etc.) corresponding to other resources.

In a possible implementation manner, when there is data to be transmitted to be sent through the at least two uplink transmission resources, the terminal controls the uplink transmission process on the at least two uplink transmission resources. The control process can be as follows:

Step 303: When there is at least one data to be transmitted that is sent through the at least two uplink transmission resources, the terminal determines a first target resource from the at least two uplink transmission resources.

In a possible implementation manner, the data to be transmitted includes at least one of the following data:

Medium access control layer protocol data unit MAC PDU, uplink scheduling request SR, preamble, ACK/NACK, and acknowledgement ACK/non-acknowledgement NACK generation indication.

In a possible implementation manner, determining the first target resource from the at least two uplink transmission resources includes:

1) Among the at least two uplink transmission resources, the resource with the highest priority is determined as the first target resource. That is to say, in the embodiment of the present application, the terminal may directly use the resource of the highest priority among the multiple uplink transmission resources as the first target resource to be detected.

For example, in this embodiment of the present application, if the network side device instructs the terminal to detect only the resource with the highest priority, the terminal may determine the resource with the highest priority among the above at least two uplink transmission resources as the first target resource.

or,

2) When the data to be transmitted is data corresponding to a single resource in the at least two uplink transmission resources, determine the single resource as the first target resource. That is, if the MAC layer of the terminal only sends data corresponding to one resource of at least two uplink transmission resources to the physical layer, the terminal may directly determine the resource corresponding to the data as the first target resource.

For example, in this embodiment of the present application, if the network side device does not instruct the terminal to only detect the resource with the highest priority, and the upper layer only sends data corresponding to a single resource to the physical layer, the terminal directly determines the single resource as the first resource. target resource.

or,

3) According to the first resource selection manner, determine the first target resource from at least two uplink transmission resources.

In a possible implementation manner, the first resource selection manner includes at least one of the following manners:

The selection is performed based on the priority of the uplink transmission resources; for example, among the at least two uplink transmission resources, the high-priority resource, or the resource with the highest priority, is selected as the above-mentioned first target resource;

The selection is performed based on the resource index of the uplink transmission resource; for example, the resource with the largest or smallest resource index index among the at least two uplink transmission resources is selected as the above-mentioned first target resource;

And, the selection is made based on the resource type of the uplink transmission resource; for example, the PRACH resource in the at least two uplink transmission resources is selected as the first target resource for detection.

In a possible implementation manner, the terminal receives the first resource selection manner indicated by the network side device. For example, after the terminal accesses the network, the network side device indicates the first resource selection mode through the above configuration information or scheduling information.

In another possible implementation manner, the terminal determines the indicated first resource selection manner through the above idle state detection manner. That is, the terminal determines the resource determined according to the indicated detection mode among the at least two uplink transmission resources as the first target resource. For example, the above-mentioned idle state detection method includes the above-mentioned first resource selection method.

For example, if the above idle state detection method indicates the detection of high-priority resources, the terminal determines that the high-priority resource is the above-mentioned first target resource; for another example, if the above-mentioned idle state detection method indicates the detection of the resource with the smallest resource index, the terminal determines that the index is the smallest. The resource is the above-mentioned first target resource; for another example, if the above-mentioned idle state detection method indicates the detection of PUCCH resources (for example, when PUCCH and PUSCH conflict), the terminal determines that the PUCCH resource is the above-mentioned first target resource; for another example, the above-mentioned idle state detection The mode indicates that the PRACH resource is detected (for example, when the PUSCH and the PRACH conflict), the terminal determines that the PRACH resource is the above-mentioned first target resource.

After the terminal acquires the first target resource, it can control the process of detecting the idle state of the first target resource, and/or, according to the idle state detection result of the first target resource, perform control on the idle state detection result of the first target resource. The data transfer process is controlled. This process can refer to the next steps.

In a possible implementation manner, when the network side device configures/indicates the priorities of at least two uplink transmission resources, the terminal can directly obtain the priorities of the at least two uplink transmission resources configured/indicated by the network side device .

or,

4) Determine the first target resource from at least two uplink transmission resources according to the indication information of the network side device.

For example, in this embodiment of the present application, the network side device may directly instruct the terminal which resource in the at least two uplink transmission resources to detect.

Step 304, the terminal performs idle state detection on the first target resource.

The above idle state detection is LBT detection, that is, in this embodiment of the present application, the terminal only performs idle state detection on the first target resource in the at least two uplink transmission resources.

For example, in the embodiment of the present application, under the condition that the first condition is satisfied, if there is resource conflict or overlap, the UE only selects the part of the resources indicated by the above idle state detection method/first resource selection method (for example, the priority is high. resource/resource with the smallest index/resource of the specified type) to perform LBT detection. The first condition is that the physical layer receives a plurality of available/to-be-transmitted information from a higher layer (MAC layer). The available/to-be-transmitted information may be at least one of the following information: MAC PDU, SR, preamble sequence preamble, ACK/NACK, and ACK/NACK generation indication.

Step 305, the terminal controls the data transmission process on the first target resource according to the idle state detection result of the first target resource.

In a possible implementation manner, the above-mentioned control of the data transmission process performed on the first target resource according to the idle state detection result of the first target resource includes at least one of the following manners:

1) When the idle state detection result of the first target resource indicates that the first target resource is idle or fails to detect (for example, no LBT failure), and the data to be transmitted includes data corresponding to the first target resource, in the Data corresponding to the first target resource is transmitted on the first target resource;

In this embodiment of the present application, if the terminal detects the resource with the highest priority, and detects that the resource is idle or fails to detect (for example, there is no LBT failure), and the resource also corresponds to data to be transmitted, the terminal is in the The corresponding data is transmitted on the resource.

2) When the idle state detection result of the first target resource indicates that the first target resource is idle or fails to detect (for example, no LBT failure), and the data to be transmitted does not contain data corresponding to the first target resource, waive this data transfer;

In this embodiment of the present application, if the terminal detects the resource with the highest priority, and detects that the resource is idle or fails to detect (for example, no LBT failure), but the resource does not have corresponding data to be transmitted, then The terminal does not perform data transmission on this resource.

3) When the idle state detection result of the first target resource indicates that the first target resource is idle or fails to detect (for example, there is no LBT failure), and the data to be transmitted does not contain data corresponding to the first target resource, The data with the highest priority among the data to be transmitted is transmitted on the first target resource.

In this embodiment of the present application, if the terminal detects the resource with the highest priority, and detects that the resource is idle or fails to detect (for example, no LBT failure), but the resource does not have corresponding data to be transmitted, then The terminal may transmit the data with the highest priority among the data corresponding to other resources on the resource.

For example, when the data corresponding to other resources has the highest priority and the transmission block size of the data is the same as the transmission block size of the resource, the terminal may transmit the data with the highest priority among the data corresponding to other resources on the resource.

Alternatively, when there is data corresponding to other resources with the same transport block size as that of the resource, the terminal may transmit data on the resource with the same transport block size as the data corresponding to the resource, and prioritize highest level data.

Or, when the transmission block size of the data with the highest priority is different from the transmission block size of the resource in the data corresponding to other resources, the terminal can reorganize the data with the highest priority, and then transmit the reorganized data on the resource. Data with the highest priority.

In a possible implementation manner, when the first target resource is the single resource, the data transmission process performed on the first target resource is controlled according to the idle state detection result of the first target resource, include:

When the idle state detection result of the first target resource indicates that the first target resource is idle or fails to detect (eg, no LBT failure), data corresponding to the first target resource is transmitted on the first target resource.

In this embodiment of the present application, if the terminal only performs LBT detection on the above single resource, and detects that it is in an idle state or has not detected a failure (eg, no LBT failure), the terminal directly transmits the data to be detected on the single resource.

For example, there are two overlapping CG resources at time t1, these two resources belong to different UL LBT bands, but belong to one BWP. If the physical layer of the terminal receives the corresponding MAC PDUs for these two CG resources, the UE only performs LBT detection on the resource with high priority. If the LBT detection for the high-priority resource is successful, the UE transmits the resource, otherwise it does not transmit.

For another example, there are two overlapping CG resources at time t1, and the two resources belong to different UL LBT bands, but belong to one BWP. If the physical layer receives only one corresponding MAC PDU for these two CG resources, the UE only performs LBT detection on the resource corresponding to the received MAC PDU, or the UE performs LBT detection only on the resource with high priority. If the LBT detection is successful, the UE transmits on the corresponding resource, otherwise it does not transmit. That is to say, if the high-priority resource is not the resource for which the MAC PDU is received, after successful detection of the high-priority resource, the MAC PDU needs to be transmitted on the high-priority resource.

Step 306, the network side device receives the uplink data transmission of the terminal.

Wherein, the network-side device only performs energy detection at the resource positions corresponding to some resources indicated by the above idle state detection method/first resource selection method (for example, resources with high priority/resources with the smallest index/resources of a specified type), and receives and decoding. Alternatively, the network-side device performs energy detection, reception and decoding at all possible resource locations.

In this embodiment of the present application, if the network side device instructs the terminal to perform idle state detection or data transmission only on some resources (for example, resources with high priority/resources with the smallest index/specified types of resources), the network side device When receiving the uplink data transmission of the terminal, the reception is performed on the indicated part of the uplink transmission resources in the at least two uplink transmission resources.

Or, if the network-side device does not indicate to the terminal to perform idle state detection or data transmission only on some resources (for example, resources with high priority/resources with the smallest index/specified types of resources), the network-side device receives the terminal's During uplink data transmission, reception is performed in the above at least two uplink transmission resources.

Or, if the terminal device is not restricted or required to perform idle state detection or data transmission only on some resources (for example, resources with high priority/resources with the smallest index/specified types of resources), the network side device receives the uplink data of the terminal During transmission, reception is always performed in the above at least two uplink transmission resources.

To sum up, in this embodiment of the present application, when there are multiple uplink transmission resources on unlicensed frequency bands at the same time, and there is conflict or overlap between the multiple uplink transmission resources, the terminal is free for the multiple uplink transmission resources. The state detection and data transmission process are controlled, thereby providing a solution for data transmission under the condition of simultaneous existence of uplink transmission resources on multiple unlicensed frequency bands, and expanding the applicable scenarios for terminals to perform data transmission on unlicensed frequency bands.

Please refer to FIG. 4 , which shows a flowchart of an uplink transmission control method provided by an embodiment of the present application. The method can be executed interactively by a terminal and a network-side device, wherein the above-mentioned terminal may correspond to the network architecture shown in FIG. 1 .

Wherein, the idle state detection method includes:

or,

or,

or,

Wherein, when the idle state detection mode indicated by the detection mode indication information is to detect the at least two uplink transmission resources respectively, the terminal may refer to the subsequent steps for the control process of uplink data transmission on the unlicensed channel.

Step 402, the terminal acquires at least two uplink transmission resources.

Step 403: When there is at least one data to be transmitted that is sent through the at least two uplink transmission resources, the terminal performs idle state detection on the at least two target resources respectively.

Step 404: Control the uplink transmission process on the at least two uplink transmission resources according to the idle state detection results of the at least two target resources.

In the embodiment of the present application, the terminal may control the uplink transmission process on the at least two uplink transmission resources according to the idle state detection results of the at least two target resources and the second resource selection manner.

In a possible implementation manner, the second resource selection manner includes at least one of the following manners:

Selection is made based on the priority of uplink transmission resources; for example, the terminal selects idle/undetected failures, and high-priority resources, or resources with the highest priority to transmit;

Select based on the resource index of the uplink transmission resource; for example, the terminal selects to transmit on the resource with the largest or smallest resource index in idle/undetected failure;

Select based on the resource type of the uplink transmission resource; for example, the terminal selects to transmit on the specified type of resource that is idle or fails to detect failure;

The selection is made based on the indication information of the network-side device; for example, the network-side device instructs the terminal device to transmit on a certain resource, and the terminal determines to transmit on the resource according to the instruction of the network-side device;

And, the selection is made based on whether the uplink transmission resource corresponds to the data to be transmitted; for example, the terminal selects to transmit on the resource that is idle/undetected and corresponds to the data to be transmitted.

In a possible implementation manner, the terminal receives the second resource selection manner indicated by the network side device. For example, after the terminal accesses the network, the network side device indicates the second resource selection mode through the above configuration information or scheduling information.

In another possible implementation manner, the network side device indicates the second resource selection manner through the above idle state detection manner, for example, the foregoing idle state detection manner includes the foregoing first resource selection manner.

In a possible implementation manner, the terminal controls the uplink transmission process on the at least two uplink transmission resources according to the idle state detection results of the at least two target resources.

In a possible implementation manner, controlling the uplink transmission process on the at least two uplink transmission resources according to the idle state detection results of the at least two target resources, includes:

1) When the idle state detection results of the at least two target resources indicate that the resources that are idle or fail to detect (for example, no LBT failure) include the second target resource, and the data to be transmitted includes the first target resource corresponding to the second target resource; When there is a data, the first data is transmitted on the second target resource; the second target resource is the resource with the highest priority among the at least two target resources, or the second target resource is the at least two target resources The resource with the smallest resource index among the at least two target resources, or the second target resource is the resource with the largest resource index among the at least two target resources, or the second target resource is a resource of a specified type;

When the idle state detection results of the at least two target resources indicate that there are multiple idle or undetected failure (eg, no LBT failure) resources, one of the idle or undetected failure (eg, no LBT failure) resources The resource is transmitted; exemplarily, the resource to be transmitted is the resource with the highest priority among multiple resources that are idle or fail to be detected (for example, no LBT failure). Exemplarily, the data transmitted by the resource to be transmitted is the data corresponding to the resource, or the data with the highest priority among all the received data to be transmitted.

2) When the idle state detection results of the at least two target resources indicate that the second target resource is not included in the resources that are idle or fail to detect (for example, no LBT failure), abandon this data transmission;

3) When the idle state detection results of the at least two target resources indicate that there are resources that are idle or fail to detect (for example, no LBT failure), transmit the second data through a third target resource; the third target resource is the at least The idle state detection results of the two target resources indicate the resource with the highest priority among the resources that are idle or fail to detect (for example, no LBT failure), or the idle state detection results of the at least two target resources indicate idle or no failure to detect The resource with the smallest resource index among the resources, or the idle state detection result of the at least two target resources indicates the resource with the largest resource index among the resources that are idle or failed to detect, or the idle state detection result of the at least two target resources Indicate the resource of the specified type in the resources that are idle or fail to be detected; the second data is the data with the highest priority in the data to be transmitted;

4) When the idle state detection results of the at least two target resources indicate that there are resources that are idle or fail to detect (for example, no LBT failure), transmit third data through the third target resource; the third data is the resource to be In the transmission data, the data corresponding to the third target resource;

5) When the idle state detection results of the at least two target resources indicate that there is an idle resource or a resource that fails to be detected, transmit fourth data through the resource that is idle or fail to detect; the fourth data is in the data to be transmitted, Data for resources that should be idle or failed to detect failures.

When the idle state detection results of the at least two target resources indicate that there are resources that are idle or fail to detect (eg, no LBT failure), the terminal transmits the resources that are idle or fail to detect (eg, no LBT failure); its transmission The resource is the data corresponding to the resource.

In the embodiment of the present application, if the first condition is satisfied, if there is resource conflict or overlap, the UE performs LBT detection on each resource, and transmits according to the LBT detection result. The first condition is that the physical layer receives a plurality of available/to-be-transmitted information from a higher layer (MAC layer). The available/to-be-transmitted information may be at least one of the following: MAC PDU, SR, preamble, ACK/NACK, and ACK/NACK generation indication.

For example, taking the network side device instructing the terminal to control resource transmission by priority as an example, the UE transmits according to the LBT detection result, including at least one of the following methods:

1) If the resources successfully detected by LBT include high-priority resources, the corresponding data is transmitted on the resources;

2) If the resources successfully detected by LBT do not include high-priority resources, the resources are not transmitted; or, the data (such as MAC PDUs) corresponding to the high-priority resources are transmitted using the resources successfully detected by LBT;

3) If the resources with successful LBT detection do not include high-priority resources, transmit the next-highest-priority resources or the low-priority resources for which LBT is successful;

4) If there is a resource successfully detected by LBT, the data corresponding to the resource is transmitted on the resource successfully detected.

For example, there are two overlapping CG resources at time t1, these two resources belong to different UL LBT bands, but belong to one BWP. If the physical layer receives the corresponding MAC PDUs for the two CG resources, the UE performs LBT detection on each resource. If the LBT detection for the high-priority resource is successful, the UE transmits the resource and the MAC PDU corresponding to the resource. If the LBT detection for the high-priority resource fails, the UE does not transmit the resource, or the UE transmits the MAC PDU corresponding to the high-priority resource using the low-priority resource for which the LBT succeeds (further conditions are the low-priority and high-priority resources The TBS is the same. Otherwise, the low-priority resource cannot be used to transmit the MAC PDU corresponding to the high-priority resource, or rebuild and reorganize the MAC PDU corresponding to the high-priority resource).

For another example, there are two overlapping CG resources at time t1, and these two resources belong to different UL LBT bands, but belong to one BWP. If the physical layer receives the corresponding MAC PDUs for the two CG resources, the UE performs LBT detection on each resource. If the LBT detection for the high-priority resource fails, but the LBT detection for the second-priority or low-priority resource succeeds, the UE uses the low-priority resource to transmit the MAC PDU corresponding to the low-priority resource.

For another example, there are two overlapping CG resources at time t1, and the two resources belong to different UL LBT bands, but belong to one BWP. If the physical layer receives only one corresponding MAC PDU for these two CG resources, the UE performs LBT detection on all resources, and selects the resources with successful LBT and high priority for transmission.

For another example, there are two overlapping CG resources at time t1, and the two resources belong to different UL LBT bands, but belong to one BWP. If the physical layer receives the corresponding MAC PDUs for these two CG resources, the UE performs LBT detection on all resources, and selects the resource with successful LBT to transmit the corresponding data regardless of the priority of the resources.

Step 405, the network side device receives the uplink data transmission of the terminal.

Among them, the network side equipment performs energy detection, reception and decoding at all possible resource locations.

In this embodiment of the present application, if the network-side device instructs the terminal to perform idle state detection on all resources, the network-side device performs reception in at least two of the above-mentioned uplink transmission resources when receiving the terminal's uplink data transmission.

The scheme shown in the embodiment of the present application provides a scheme of performing LBT detection on all resources and selecting a successful LBT resource for transmission, which avoids waste of resources and ensures the transmission requirements of URLLC services as much as possible.
