Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

The network architecture and the service scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not constitute a limitation to the technical solution provided in the embodiment of the present application, and it can be known by a person skilled in the art that the technical solution provided in the embodiment of the present application is also applicable to similar technical problems along with the evolution of the network architecture and the appearance of a new service scenario.

Referring to fig. 1, a schematic diagram of a network architecture of a communication system according to an embodiment of the present application is shown. The network architecture may include: a terminal 10 and a base station 20.

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

The base station 20 is a device deployed in an access network to provide a wireless communication function for the terminal 20. 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 having a base station function may be different, for example, in a 5th-Generation (5G) NR system, referred to as a gbnodeb or a gNB. The name "base station" may change as communication technology evolves. For convenience of description, in the embodiment of the present application, the above-mentioned apparatuses providing the terminal 20 with the wireless communication function are collectively referred to as a base station.

Optionally, not shown in fig. 1, the network architecture further includes other network devices, such as: a Central Network Control (CNC), an Access and Mobility Management Function (AMF) device, a Session Management Function (SMF) or User Plane Function (UPF) device, and so on.

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 the meaning thereof. The technical scheme described in the embodiment of the present disclosure may be applied to a 5G NR system, and may also be applied to a subsequent evolution system of the 5G NR system.

For ease of understanding, reference will now be made to some of the relative terms referred to in this application:

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

The URLLC requirement supports the transmission of services such as industrial Automation (Factory Automation), transport Automation (Transport Industry), intelligent Power (Electrical Power Distribution) and the like in a 5G system. In order to support transmission of URLLC services, the 5G standard enhances Configuration Grant (CG), that is, multiple CG configurations are introduced, and specific configurations and uses of CGs (such as a slot-level supporting period, automatic transmission of CGs, and the like) are enhanced.

In view of the need to support URLLC services in an interference-controlled NR-U scenario, the following enhancements may be made:

a. the use mode of NRU CG and URLLC CG enhancement in an NR-U scene;

b. UE-initial Channel Occupancy Time (COT) for FBE.

2) CG enhancement in URLLC

In order to support the high delay requirement of the URLLC service, the URLLC strengthens a CG period and supports any slot-level service period.

To support multiple URLLC services and the high latency requirements of URLLC services, URLLC has also introduced the multiple CG (multiple CG) concept. Besides, the HARQ processes configured by different CGs are different, and the processes of different CGs are ensured to be different through HARQ-ProcID-Offset 2.

Because there is a CG resource and other resource conflict, in order to ensure that a Media Access Control Protocol Data Unit (MAC PDU) (i.e. a prioritized MAC PDU) that has been packaged in the CG resource is not discarded, or ensure that the prioritized MAC PDU is transmitted as soon as possible, automatic transmission for the CG is introduced. That is, for the CG which is corresponding to the packaged MAC PDU and cannot be transmitted due to resource collision, the CG resource in the same CG configuration in the same subsequent HARQ process may be used for new transmission. For example, the use of automatic transmission is determined by autonomousTx.

The MAC may indicate one or more MAC PDUs to the physical layer if there is a CG to CG collision due to different physical layer priorities. Similarly, if there is a conflict between service data (data) and an uplink Scheduling Request (SR), the MAC may also indicate the SR and the MAC PDU to the physical layer.

3)NR-U

The NR works in an unlicensed frequency band, and includes the following working scenarios:

scene A: in a carrier aggregation scenario, a Primary Cell (PCell) is a licensed spectrum, and a Secondary Cell (SCell) working on an unlicensed spectrum is aggregated in a carrier aggregation manner;

scene B: in a dual-connection working scene, a PCell is a Long Term Evolution (LTE) authorized spectrum, and a PScell is an NR unauthorized spectrum;

scene C: in an independent working scene, NR is used as an independent cell to work in an unauthorized frequency spectrum;

scene D: in the NR single cell scenario, an uplink (Up Link, UL) operates in a licensed spectrum, and a downlink (Down Link, DL) operates in an unlicensed spectrum;

scene E: in a double-connection working scene, PCell is an NR authorized spectrum, and PScell is an NR unauthorized spectrum.

Generally, the operating Band (Band) of NR-U is 5GHz unlicensed spectrum and 6GHz unlicensed spectrum. On unlicensed spectrum, the design of NR-U should guarantee fairness with other systems already operating on these unlicensed spectrum, such as Wireless Fidelity (Wi-Fi). The principle of fairness is that the impact of NR-U on systems already deployed on unlicensed spectrum (such as Wi-Fi) cannot exceed the impact between these systems.

In order to ensure fair coexistence between systems over unlicensed spectrum, energy detection has been identified as a basic coexistence mechanism. A general energy detection mechanism is a Listen Before Talk (LBT) mechanism, and the basic principle of the mechanism is as follows: the base station or the terminal (transmission end) needs to listen for a certain period of time as specified before transmitting data on the unlicensed spectrum. If the sensed result indicates that the channel is in an idle state, the transmitting end may transmit data to the receiving end. If the interception result indicates that the channel is in an occupied state, the transmission end needs to back off for a period of time according to the specification and then continue to intercept the channel, and the data can be transmitted to the receiving end only if the channel interception result is in an idle state.

Four channel access mechanisms (categories) are currently defined in NR-U:

category 1: direct transmission mechanism

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

switching gap refers to the transition time for a received transmission, typically no more than 16us.

Category 2: LBT mechanism without random back-off

This mechanism means that the time for the UE to listen to the channel is certain, and is typically short, for example 25us.

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

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

Category 4: LBT mechanism of random back-off (contention window is not fixed)

In the LBT procedure, the transmitting side randomly takes a random value in a contention window to decide the time for listening to the channel, and the contention window is variable.

By the above, for the terminal, the base station needs to transmit data to the terminal within the maximum channel occupancy time (Max COT, MCOT); if the base station does not preempt the channel, i.e., outside the MCOT time, the terminal does not receive the scheduling data from the base station to the terminal.

4) Upstream LBT failure in NR-U

For uplink transmission initiated by UE, there are several categories as follows:

SR: for requesting uplink resources;

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

physical Uplink Shared Channel (PUSCH): the method comprises the steps of uplink data transmission based on configured grant and uplink data transmission based on dynamic grant;

physical layer signaling transmission: the method comprises acknowledgement ACK/non-acknowledgement NACK feedback, channel State Information (CSI) reporting and the like.

On the unlicensed band, before the UE transmits SR, PRACH, or PUSCH, LBT is first used to sense whether the channel is available, and if not, i.e. LBT fails, the UE needs to wait until the next transmission opportunity to perform LBT again. If detecting the LBT failure, it needs to inform the MAC layer of the LBT failure information.

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

For R16NR-U, no resource collision scenario is considered, in R16NR-U, the physical layer will only receive one resource from a higher layer that needs to be transmitted. Therefore, there is no provision for how to perform the LBT test. In R17, in order to support the priority transmission of the high-priority resource (e.g., the priority transmission of the resource corresponding to the URLLC service), the higher layer may indicate to the physical layer a plurality of resources that can be transmitted, such as a plurality of MAC PDUs, or MAC PDU + SR, etc., and at this time, how to perform LBT detection and data transmission needs to be considered.

The subsequent embodiments of the present application propose a scheme for performing data transmission when the higher layer MAC indicates uplink transmission resources in multiple unlicensed frequency bands to the physical layer.

The technical solution of the present application will be described below with reference to several exemplary embodiments.

Referring to fig. 2, a flowchart of an uplink transmission control method according to an embodiment of the present application is shown, where the method is applicable to a terminal in a communication system corresponding to the network architecture shown in fig. 1, and the method may include the following steps:

step 201, at least two uplink transmission resources are obtained, where the at least two uplink transmission resources are resources on an unlicensed frequency band, and there is a collision or an overlap between the at least two uplink transmission resources.

In a possible implementation manner, the at least two uplink transmission resources are resources indicated by a higher layer (such as a MAC layer) to a physical layer of the terminal.

In a possible implementation manner, the at least two uplink transmission resources are configured or scheduled by the network side.

Step 202, controlling an uplink transmission process on the at least two uplink transmission resources; the uplink transmission procedure includes an idle state detection procedure and/or a transmission procedure.

In a possible implementation manner, the terminal obtains the priorities of the at least two uplink transmission resources, and controls the uplink transmission process on the at least two uplink transmission resources according to the priorities.

In a possible implementation manner, the priorities of the at least two uplink transmission resources are statically configured in the terminal.

In a possible implementation manner, the priorities of the at least two uplink transmission resources are configured or indicated by the network side.

In a possible implementation manner, the priorities of the at least two uplink transmission resources are determined by the terminal according to a preset manner.

In the solution shown in the embodiment of the present application, when uplink transmission resources on multiple unlicensed frequency bands exist in a terminal at the same time and there is a conflict or an overlap between the multiple uplink transmission resources, the terminal may control at least one of an idle state detection process and a transmission process of the multiple uplink transmission resources.

In one possible implementation, the idle state detection is LBT detection.

In a possible implementation manner, the terminal may control the idle state detection process on at least two uplink transmission resources through information indicated by the network side device.

In a possible implementation manner, the terminal may control the uplink transmission process on the at least two uplink transmission resources through information indicated by the network side device.

In summary, in the embodiment of the present application, when uplink transmission resources on multiple unlicensed frequency bands exist at the same time and there is a conflict or an overlap between the multiple uplink transmission resources, the terminal controls idle state detection and/or a data transmission process of the multiple uplink transmission resources, so as to provide a scheme for performing data transmission when uplink transmission resources on multiple unlicensed frequency bands exist at the same time, and expand an application scenario of the terminal for performing data transmission on the unlicensed frequency bands.

In the solution shown in the above embodiment of the present application, when the terminal controls the uplink transmission process on the at least two uplink transmission resources, the terminal may control the idle state detection process, may also control the data transmission process, and may also control both the idle state detection process and the data transmission process. The following embodiments of the present application will respectively introduce different control modes.

Please refer to fig. 3, which shows a flowchart of an uplink transmission control method according to an embodiment of the present application, where the method may be performed by a terminal and a network-side device in an interactive manner, where the terminal may be a terminal in a communication system corresponding to the network architecture shown in fig. 1, and 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 steps of:

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

Wherein the configuration information or the scheduling information is used for indicating at least two uplink transmission resources.

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

In a possible implementation manner, the configuration information or the scheduling information is further used for configuring or indicating the priority of the at least two uplink transmission resources.

In a possible implementation manner, the network side device further sends detection manner indication information to the terminal, where the detection manner indication information is used to indicate a manner of idle state detection; 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 manner for the terminal, or the terminal is preset with at least one idle state detection manner; the terminal may determine which idle state detection method is used by itself, or the terminal may use one of the multiple idle state detection methods according to an instruction of the network side device.

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

Wherein, the idle state detection mode comprises:

selecting 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 resource (e.g., PRACH resource); for another example, the network side device may instruct the terminal to detect a type of resource (e.g., PRACH resource) belonging to a certain type;

or,

selecting one resource from the at least two uplink transmission resources for detection; for example, the terminal detects one resource in which the priority is highest and/or the resource index is smallest. 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,

selecting 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 3 resources with the highest priority or the smallest resource index; for another example, the terminal detects 3 resources with the highest priority or the smallest resource index; for another example, the terminal detects 3 resources therein;

or,

detecting the at least two uplink transmission resources respectively; for example, the terminal determines itself or detects at least two uplink transmission resources respectively according to a predefined manner; for another example, the network side device may instruct the terminal to detect at least two uplink transmission resources respectively.

In a possible implementation manner, the uplink transmission resource includes:

dynamically authorizing DG resources, configuring authorized CG resources, physical Uplink Control Channel (PUCCH) resources, or Physical Random Access Channel (PRACH) resources.

In this embodiment, a network side device may configure a resource or schedule resource transmission for a terminal, where the configuration information or the scheduling information may indicate as follows:

1) The configured/scheduled resources can be DG resources, CG resources, PUCCH resources, PRACH resources and the like;

2) Configuring or indicating priority information for the configured/scheduled resources while configuring/scheduling the resources;

wherein the indicated priority information may include a high priority indication, and a low priority indication;

alternatively, the priority information may comprise more levels of priority indication, such as at least three levels of priority indication.

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

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

In another possible implementation manner, the terminal may obtain 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 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) Indicating the LBT detection mode, such as detecting only which type of resource (e.g., high priority resource) or all resources.

When the idle state detection mode indicated by the detection mode indication information is to select at least one specified type/one specified number of resources from the at least two uplink transmission resources for detection, the terminal may refer to the subsequent step in the uplink data transmission control process on the unlicensed channel.

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

In this embodiment, a higher layer (e.g., a MAC layer) in the terminal may indicate the at least two uplink transmission resources to the physical layer, for example, in a URLLC transmission scenario, the MAC layer may indicate multiple CG resources to the physical layer, or indicate CG resources and other resources to the physical layer at the same time.

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

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

step 303, when there is at least one to-be-transmitted data transmitted through the at least two uplink transmission resources, the terminal determines a first target resource from the at least two uplink transmission resources.

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

the method comprises the following steps of a medium access control layer protocol data unit (MAC PDU), an uplink Scheduling Request (SR), a preamble, an Acknowledgement (ACK)/Negative Acknowledgement (NACK) and an ACK/NACK generation indication.

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

1) And determining the resource with the highest priority in the at least two uplink transmission resources as the first target resource. That is to say, in the embodiment of the present application, the terminal may directly use a type of resource with 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 indicates that the terminal only detects the resource with the highest priority, the terminal may determine, as the first target resource, the resource with the highest priority in the at least two uplink transmission resources.

Or,

2) And when the data to be transmitted is data corresponding to a single resource in the at least two uplink transmission resources, determining the single resource as the first target resource. That is, if the MAC layer of the terminal sends only data corresponding to one resource of the 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 detect only the resource with the highest priority, and the higher layer sends only data corresponding to a single resource to the physical layer, the terminal directly determines the single resource as the first target resource.

Or,

3) And determining a first target resource from at least two uplink transmission resources according to the first resource selection mode.

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

selecting based on the priority of the uplink transmission resource; for example, a resource with a high priority or a resource with a highest priority among the at least two uplink transmission resources is selected as the first target resource;

selecting based on a resource index of the uplink transmission resource; for example, the resource with the largest or smallest resource index among the at least two uplink transmission resources is selected as the first target resource;

and selecting based on the resource type of the uplink transmission resource; for example, a PRACH resource of 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 manner through the configuration information or the scheduling information.

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

For example, if the idle state detection mode indicates to detect a high priority resource, the terminal determines that the high priority resource is the first target resource; for another example, if the idle state detection mode indicates that the resource with the smallest index is detected, the terminal determines that the resource with the smallest index is the first target resource; for another example, if the idle state detection mode indicates detection of a PUCCH resource (for example, when the PUCCH and PUSCH collide), the terminal determines that the PUCCH resource is the first target resource; for another example, if the idle state detection mode indicates detection of PRACH resources (e.g., when PUSCH and PRACH collide), the terminal determines that the PRACH resource is the first target resource.

After the terminal acquires the first target resource, the process of idle state detection of the first target resource can be controlled, and/or the process of data transmission on the first target resource is controlled according to the idle state detection result of the first target resource. The process may refer to the subsequent steps.

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

Or,

4) And determining a first target resource from at least two uplink transmission resources according to the indication information of the network side equipment.

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

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

In this embodiment, the terminal only performs idle state detection on a first target resource of the at least two uplink transmission resources.

For example, in the embodiment of the present application, if there is a resource conflict or overlap when the first condition is satisfied, the UE performs LBT detection on only a part of the resources indicated by the idle state detection method/first resource selection method (for example, the resource with the highest priority/the resource with the smallest index/the resource of the designated type). The first condition is that the physical layer receives a number of available/pending messages from higher layers (MAC layer). The available/to-be-transmitted information may be at least one of the following information: MAC PDU, SR, preamble sequence preamble, acknowledgement ACK/non-acknowledgement NACK, and ACK/NACK generation indication.

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

In a possible implementation manner, the above controlling, according to the idle state detection result of the first target resource, a data transmission process performed on 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 unsuccessfully detected (for example, there is no LBT failure), and the to-be-transmitted data includes data corresponding to the first target resource, transmitting the data corresponding to the first target resource on the first target resource;

in this embodiment of the present application, if the terminal detects a resource with the highest priority, and detects that the resource is idle or fails to detect (for example, there is no LBT failure), and meanwhile, the resource also corresponds to data to be transmitted, the terminal transmits the corresponding data 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 (e.g., there is no LBT failure), and the data to be transmitted does not include data corresponding to the first target resource, abandoning the data transmission;

in this embodiment of the present application, if the terminal detects a resource with the highest priority, and detects that the resource is idle or fails to detect (for example, there is no LBT failure), but the resource does not have corresponding data to be transmitted, the terminal does not perform data transmission on the 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 (e.g., there is no LBT failure), and the data to be transmitted does not include data corresponding to the first target resource, transmitting data with the highest priority among the data to be transmitted on the first target resource.

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

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

Alternatively, when there is data having a transport block size that is the same as the transport block size of the resource among data corresponding to other resources, the terminal may transmit data having the highest priority among the data having the transport block size that is the same as the transport block size of the data corresponding to the resource on the resource.

Or, when the size of the transport block of the data with the highest priority is different from the size of the transport block of the resource in the data corresponding to the other resources, the terminal may reassemble the data with the highest priority and then transmit the reassembled data with the highest priority on the resource.

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

when the idle state detection result of the first target resource indicates that the first target resource is idle or fails to detect (e.g., no LBT failure), transmitting data corresponding to the first target resource on the first target resource.

In this embodiment of the present application, if the terminal performs LBT detection only on the above single resource and detects that the terminal is in an idle state or a non-detection failure state (for example, no LBT failure), the terminal directly transmits data to be detected on the single resource.

For example, there are two overlapping CG resources at time t1, which belong to different UL LBT bands but to one BWP. If the physical layer of the terminal receives the corresponding MAC PDU aiming at the two CG resources, the UE only carries out LBT detection on the resource with high priority. And if the LBT detection aiming at the resource with high priority is successful, the UE transmits the resource, otherwise, the UE does not transmit.

As another example, there are two overlapping CG resources at time t1, which belong to different UL LBT bands but to one BWP. If the physical layer only receives one corresponding MAC PDU for the two CG resources, the UE only performs LBT detection on the resources corresponding to the received MAC PDU, or the UE only performs LBT detection on the resources with high priority. And if the LBT detection is successful, the UE transmits on the corresponding resource, otherwise, the UE does not transmit. That is, if the high priority resource is not the resource for receiving the MAC PDU, after the high priority resource is successfully detected, 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.

The network side device performs energy detection, reception and decoding only at resource positions corresponding to part of the resources (for example, the resource with the highest priority/the resource with the smallest index/the resource of the designated type) indicated by the idle state detection method/the first resource selection method. Or, 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 indicates to the terminal that idle state detection or data transmission is only performed on a part of resources (for example, a resource with a high priority/a resource with a minimum index/a resource of a specified type), the network side device receives, when receiving uplink data transmission of the terminal, the indicated part of uplink transmission resources among the at least two uplink transmission resources.

Or, if the network-side device does not indicate to the terminal that idle state detection or data transmission is performed only on a part of resources (e.g., a resource with a high priority/a resource with a minimum index/a resource of a specified type), the network-side device performs reception on both of the at least two uplink transmission resources when receiving uplink data transmission of the terminal.

Or, if the terminal device is not limited or required to perform idle state detection or data transmission only on a part of resources (e.g., the resource with the highest priority/the resource with the smallest index/the resource of the designated type), the network side device always performs reception on both of the at least two uplink transmission resources when receiving the uplink data transmission of the terminal.

In summary, in the embodiment of the present application, when uplink transmission resources on multiple unlicensed frequency bands exist at the same time and there is a conflict or overlap between multiple uplink transmission resources, the terminal controls idle state detection and a data transmission process of the multiple uplink transmission resources, so as to provide a scheme for performing data transmission in the case that uplink transmission resources on multiple unlicensed frequency bands exist at the same time, and expand an application scenario of the terminal for data transmission on the unlicensed frequency bands.

Please refer to fig. 4, which shows a flowchart of an uplink transmission control method according to an embodiment of the present application, where the method may be interactively executed by a terminal and a network side device, where the terminal may be a terminal in a communication system corresponding to the network architecture shown in fig. 1, and 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 steps of:

step 401, a network side device sends configuration information or scheduling information to a terminal; correspondingly, the terminal receives the configuration information or the scheduling information sent by the network side equipment.

In this embodiment of the present application, the network side device may configure at least one idle state detection manner for the terminal, or the terminal is preset with at least one idle state detection manner; the terminal may determine which idle state detection method is used by itself, or the terminal may use one of the multiple idle state detection methods according to the indication of the network side device.

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

Wherein, the idle state detection mode comprises:

selecting at least one resource of a specified category from the at least two uplink transmission resources for detection;

or,

selecting one resource from the at least two uplink transmission resources for detection;

or,

or,

and respectively detecting the at least two uplink transmission resources.

In a possible implementation manner, the uplink transmission resource includes:

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 in the process of performing uplink data transmission control on the unlicensed channel.

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

step 403, when there is at least one to-be-transmitted data transmitted through the at least two uplink transmission resources, the terminal performs idle state detection on the at least two target resources respectively.

Step 404, controlling the uplink transmission process on the at least two uplink transmission resources according to the idle state detection result of the at least two target resources.

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

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

selecting based on the priority of the uplink transmission resource; for example, the terminal selects a resource with idle/undetected failure and high priority or a resource with highest priority for transmission;

selecting based on a resource index of the uplink transmission resource; for example, the terminal selects to transmit on the resource with the largest or smallest resource index and failed idle/undetected;

selecting based on a resource type of the uplink transmission resource; for example, the terminal selects to transmit on the specified type of resource that is idle/not detected to fail;

selecting based on the indication information of the network side equipment; for example, the network side device instructs the terminal device to perform transmission on a certain resource, and the terminal determines to perform transmission on the resource according to the instruction of the network side device;

selecting whether the uplink transmission resource corresponds to the data to be transmitted or not; for example, the terminal selects to transmit on the resource where the idle/undetected failure and corresponding 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 manner through the configuration information or the scheduling information.

In another possible implementation manner, the network side device indicates the second resource selection manner through the idle state detection manner, for example, the idle state detection manner includes the 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, the 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 which are idle or have not failed to detect (for example, no LBT failure) include a second target resource and the data to be transmitted includes first data corresponding to the second target resource, transmitting the first data on the second target resource; the second target resource is a resource with the highest priority among the at least two target resources, or the second target resource is a resource with the smallest resource index among the at least two target resources, or the second target resource is a 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 a plurality of resources which are idle or fail to detect (e.g., no LBT failure) exist, transmitting one of the resources which are idle or fail to detect (e.g., no LBT failure); illustratively, the transmitted resource is a resource with a highest priority among a plurality of resources that are idle or have not failed detection (e.g., have no LBT failure). Illustratively, the data transmitted by the transmitted resource 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 which are idle or failed to detect (for example, no LBT failure), abandoning the data transmission;

3) Transmitting second data through a third target resource when idle state detection results of the at least two target resources indicate that there are resources that are idle or have failed in detection (e.g., no LBT failure); the third target resource is a resource with the highest priority among the resources with idle state detection results of the at least two target resources indicating idle or undetected failure (e.g., no LBT failure), or the idle state detection results of the at least two target resources indicate a resource with the smallest resource index among the resources with idle or undetected failure, or the idle state detection results of the at least two target resources indicate a resource with the largest resource index among the resources with idle or undetected failure, or the idle state detection results of the at least two target resources indicate a specified type of resource among the resources with idle or undetected failure; the second data is the data with the highest priority in the data to be transmitted;

4) Transmitting third data through the third target resource when the idle state detection results of the at least two target resources indicate that there are resources that are idle or have failed in detection (e.g., no LBT failure); the third data is data corresponding to the third target resource in the data to be transmitted;

5) When the idle state detection results of the at least two target resources indicate that the idle or undetected failed resources exist, transmitting fourth data through the idle or undetected failed resources; the fourth data is data of the resource corresponding to the idle or undetected failure in the data to be transmitted.

When the idle state detection results of the at least two target resources indicate that there are idle or undetected resources (e.g., no LBT failure), the terminal transmits the idle or undetected resources (e.g., no LBT failure); the resource transmitted by it is the data corresponding to the resource.

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

For example, taking an example that the network side device instructs the terminal to control resource transmission by priority, the UE performs transmission according to the LBT detection result, including at least one of the following manners:

1) If the LBT detection success resources comprise high-priority resources, transmitting corresponding data on the resources;

2) If the LBT detection success resources do not include the high priority resources, the resources are not transmitted; or, transmitting data (such as MAC PDU) corresponding to the high priority resource by using the successful LBT resource;

3) If the LBT detection success resources do not comprise the high-priority resources, transmitting the second high-priority resources or the low-priority resources with LBT success;

4) And if the LBT successfully detected resource exists, transmitting data corresponding to the resource on the successfully detected resource.

For example, there are two overlapping CG resources at time t1, which belong to different UL LBT bands but to one BWP. If the physical layer receives the corresponding MAC PDU for the two CG resources, the UE performs LBT detection on each resource. And if the LBT detection aiming at the resource with high priority is successful, the UE transmits the resource and the MAC PDU corresponding to the resource. If LBT detection for the high-priority resource fails, the UE does not transmit the resource, or the UE uses the LBT successful low-priority resource to transmit the MAC PDU corresponding to the high-priority resource (further condition is that TBS of the low-priority resource is the same as TBS of the high-priority resource, otherwise, the low-priority resource cannot be used to transmit the MAC PDU corresponding to the high-priority resource, or the MAC PDU corresponding to the high-priority resource is rebuilt).

Also for example, at time t1 there are two overlapping CG resources belonging to different UL LBT bands but to one BWP. If the physical layer receives the corresponding MAC PDU for the two CG resources, the UE performs LBT detection on each resource. And if the LBT detection aiming at the resource with high priority fails, but the LBT detection aiming at the resource with second priority or low priority succeeds, the UE transmits the MAC PDU corresponding to the low priority resource by using the low priority resource.

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

As another example, there are two overlapping CG resources at time t1, which belong to different UL LBT bands but to one BWP. If the physical layer receives the corresponding MAC PDU aiming at the two CG resources, the UE carries out LBT detection on all the resources, and selects the resources with successful LBT to transmit corresponding data without considering the priority of the resources.

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

The network side equipment detects, receives and decodes energy at all possible resource positions.

In this embodiment, if the network side device instructs the terminal to perform idle state detection on all resources, the network side device receives the uplink data in the at least two uplink transmission resources when receiving uplink data transmission of the terminal.

The scheme shown in the embodiment of the application provides a scheme for carrying out LBT detection on all resources and selecting the resources which are successful in LBT for transmission, so that the waste of the resources is avoided, and the URLLC service transmission requirement is ensured as much as possible.

In summary, in the embodiment of the present application, when uplink transmission resources on multiple unlicensed frequency bands exist at the same time and there is a conflict or an overlap between the multiple uplink transmission resources, the terminal controls idle state detection and a data transmission process of the multiple uplink transmission resources, so as to provide a scheme for performing data transmission when uplink transmission resources on multiple unlicensed frequency bands exist at the same time, and expand an application scenario of the terminal for performing data transmission on the unlicensed frequency bands.
