Description

Transmission method and device

Technical Field

The embodiment of the application relates to the technical field of communication, in particular to a transmission method and device.

Background

The internet of vehicles (V2X) is a key technology of future intelligent transportation systems. It enables vehicle to vehicle (V2V), vehicle to roadside infrastructure (V2I), vehicle to pedestrian (V2P), or vehicle to network (V2N) communication. As shown in fig. 1, for example, V2V communication and V2I communication are used, safety information such as the speed, the driving direction, the specific position, whether an emergency brake is stepped on and the like of the vehicles can be broadcasted to surrounding vehicles through V2V communication, and the surrounding vehicles can better sense traffic conditions outside the sight distance by acquiring the safety information, so that advance judgment is made on dangerous conditions and avoidance is made. For V2I communication, in addition to the above-mentioned interaction of security information, roadside infrastructure (e.g., Road Side Unit (RSU)) can provide various service information and data network access for vehicles, and functions such as toll collection and in-vehicle entertainment greatly improve traffic intelligence.

In the prior art, LTE V2X service (referred to as V2X service transmitted in LTE system) is broadcast only, that is, one terminal can transmit LTE V2X service on any one of dedicated resources and contention resources on a sidelink in a broadcast manner. Therefore, there may be some terminals that receive the LTE V2X service and some terminals that do not receive the LTE V2X service. This does not guarantee a high Quality of Service (QoS) requirement. The NR V2X service (referred to as V2X service transmitted in NR) supports unicast and multicast, and the NR V2X service has higher QoS requirements than the LTE V2X service, so how to improve the high-reliability communication of the V2X service is an urgent problem to be solved.

In the present application, for convenience of description, a Chip disposed in the device, such as a System-On-a-Chip (SOC), a baseband Chip, or other chips having a communication function, may also be referred to as a terminal.

The terminal can be a vehicle with a corresponding communication function, or a vehicle-mounted communication device, or other embedded communication devices, or can be a user handheld communication device, including a mobile phone, a tablet computer, and the like.

It should be understood that, in the drawings in the embodiments of the present application, a terminal is taken as an example of an automobile.

As an example, in the embodiment of the present application, the terminal may also be a wearable device. Wearable equipment can also be called wearable intelligent equipment, is the general term of applying wearable technique to carry out intelligent design, develop the equipment that can dress to daily wearing, like glasses, gloves, wrist-watch, dress and shoes etc.. A wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user. The wearable device is not only a hardware device, but also realizes powerful functions through software support, data interaction and cloud interaction. The generalized wearable smart device includes full functionality, large size, and can implement full or partial functionality without relying on a smart phone, such as: smart watches or smart glasses and the like, and only focus on a certain type of application functions, and need to be used in cooperation with other devices such as smart phones, such as various smart bracelets for physical sign monitoring, smart jewelry and the like.

Network device 10 is an entity that may be used in conjunction with terminal 20 to transmit or receive signals. For example, the Access Point (AP) in the WLAN may be an evolved Node B (eNB) or eNodeB in the LTE, or a relay station or an Access Point, or a vehicle-mounted device, a wearable device, and a network device in a future 5G network or a network device in a future evolved PLMN network, and the like.

In addition, in the embodiment of the present invention, the network device provides a service for a cell, and the terminal communicates with the network device through a transmission resource (for example, a time domain resource, or a frequency domain resource, or a time frequency resource) used by the cell. The cell may be a cell corresponding to a network device (e.g., a base station), and the cell may belong to a macro base station or a base station corresponding to a small cell (small cell), where the small cell may include: urban cell (metro cell), micro cell (microcell), Pico cell (Pico cell), femto cell (femto cell), etc., which have the characteristics of small coverage and low transmission power, and are suitable for providing high-rate data transmission service.

Since the future access network may be implemented by using a cloud radio access network (C-RAN) architecture, a possible way is to divide the protocol stack architecture and functions of the conventional base station into two parts, one part is called a Central Unit (CU) and the other part is called a Distributed Unit (DU), and the actual deployment ways of the CUs and the DU are flexible, for example, CU parts of a plurality of base stations are integrated together to form a functional entity with a large scale. Fig. 3 is a schematic diagram of a network architecture according to an embodiment of the present application. As shown in fig. 3, the Network architecture includes a Core Network (CN) device and an Access Network (RAN) device. The RAN device includes a baseband device and a radio frequency device, where the baseband device may be implemented by one node or by multiple nodes, and the radio frequency device may be implemented independently by being pulled away from the baseband device, may also be integrated in the baseband device, or may be partially pulled away and partially integrated in the baseband device. For example, in an LTE communication system, a RAN device (eNB) includes a baseband device and a Radio frequency device, where the Radio frequency device may be arranged in a Remote manner with respect to the baseband device (e.g., a Radio Remote Unit (RRU) is arranged with respect to a baseband processing Unit (BBU)), and the RAN device is implemented by a node, and the node is configured to implement functions of Protocol layers such as Radio Resource Control (RRC), Packet Data Convergence Protocol (PDCP), Radio Link Control (RLC), and Medium Access Control (MAC). As another example, in an evolution structure, a baseband device may include a Centralized Unit (CU) and a Distributed Unit (DU), and a plurality of DUs may be centrally controlled by one CU. As shown in fig. 3, the CU and the DU may be divided according to protocol layers of the wireless network, for example, functions of a packet data convergence layer protocol layer and above protocol layers are disposed in the CU, such as the CU having an RRC protocol layer function and a PDCP protocol layer function; the protocol layers below the PDCP layer, such as Radio Link Control (RLC) and medium access Control (mac) layers, and the physical layer, are provided in the DU.

This division of the protocol layers is only an example, and it is also possible to divide the protocol layers at other protocol layers, for example, at the RLC layer, and the functions of the RLC layer and the protocol layers above are set in the CU, and the functions of the protocol layers below the RLC layer are set in the DU; alternatively, the functions are divided into some protocol layers, for example, a part of the functions of the RLC layer and the functions of the protocol layers above the RLC layer are provided in the CU, and the remaining functions of the RLC layer and the functions of the protocol layers below the RLC layer are provided in the DU. In addition, the processing time may be divided in other manners, for example, by time delay, a function that needs to satisfy the time delay requirement for processing is provided in the DU, and a function that does not need to satisfy the time delay requirement is provided in the CU.

In addition, the radio frequency device may be pulled away, not placed in the DU, or integrated in the DU, or partially pulled away and partially integrated in the DU, which is not limited herein.

In addition, with continuing reference to fig. 4, with respect to the architecture shown in fig. 3, the Control Plane (CP) and the User Plane (UP) of the CU may be separated and implemented by being divided into different entities, i.e. a control plane CU entity (CU-CP entity) and a user plane CU entity (CU-UP entity), respectively.

In the above network architecture, data generated by a CU may be transmitted to a terminal through a DU, or data generated by a terminal may be transmitted to a CU through a DU. The DU may not parse the data and directly encapsulate the data through a protocol layer and transmit the encapsulated data to the terminal or CU. For example, data of the RRC or PDCP Layer is finally processed into data of a Physical Layer (PHY) and transmitted to the terminal, or converted from received data of the PHY Layer. Under this architecture, the data of the RRC or PDCP layer can also be considered to be transmitted by the DU.

In the above embodiment, the CU is divided into the access network devices in the RAN, and in addition, the CU may also be divided into the access network devices in the CN, which is not limited herein.

The apparatus in the following embodiments of the present application may be located in a terminal or an access network device according to the implemented functions. When the above structure of CU-DU is adopted, the network device may be a CU node, or a DU node, or a RAN device including the functions of the CU node and the DU node.

As shown in fig. 5, fig. 5 is a schematic diagram illustrating a hardware structure of a communication device according to an embodiment of the present application.

Optionally, the communication device may also include a memory 42.

The memory 42 may be, but is not limited to, a read-only memory (ROM) or other type of static storage device that may store static information and instructions, a Random Access Memory (RAM) or other type of dynamic storage device that may store information and instructions, an electrically erasable programmable read-only memory (EEPROM), a compact disc read-only memory (CD-ROM) or other optical disk storage, optical disk storage (including compact disc, laser disc, optical disc, digital versatile disc, blu-ray disc, etc.), magnetic disk storage media or other magnetic storage devices, or any other medium that can be used to carry or store desired program code in the form of instructions or data structures and that can be accessed by a computer. The memory may be separate and coupled to the processor via a communication line 44. The memory may also be integral to the processor.

The memory 42 is used for storing computer-executable instructions for executing the present application, and is controlled by the processor 41 to execute. The processor 41 is configured to execute computer-executable instructions stored in the memory 42, so as to implement the policy control method provided by the following embodiments of the present application.

Optionally, the computer-executable instructions in the embodiments of the present application may also be referred to as application program codes, which are not specifically limited in the embodiments of the present application.

In particular implementations, processor 41 may include one or more CPUs such as CPU0 and CPU1 in fig. 5, for example, as one embodiment.

In particular implementations, the communication device may include multiple processors, such as processor 41 and processor 45 in fig. 5, for example, as an embodiment. Each of these processors may be a single-core (single-CPU) processor or a multi-core (multi-CPU) processor. A processor herein may refer to one or more devices, circuits, and/or processing cores for processing data (e.g., computer program instructions).

The transmission method provided by the embodiment of the present application will be specifically described below with reference to fig. 2 to 4.

It should be noted that, in the following embodiments of the present application, names of messages between network elements or names of parameters in messages are only an example, and other names may also be used in a specific implementation, which is not specifically limited in this embodiment of the present application.

It should be noted that the embodiments of the present application may refer to or refer to each other, for example, the same or similar steps, method embodiments, communication system embodiments and apparatus embodiments may refer to each other, and are not limited.

As shown in fig. 6, fig. 6 is a schematic flowchart of interaction of a transmission method provided in the embodiment of the present application, where the method includes:

step 101, the network device determines service information and a resource usage mode corresponding to the service information.

Wherein the resource usage pattern includes: any one of dedicated resource mode, contention resource mode, joint use of dedicated resources, and contention resource mode.

It should be understood that the joint use of dedicated resources and contention resource mode can be used in either dedicated or contention resource mode.

Wherein the service information comprises any one or more of the following information: class of service Identifier (QCI), LCH information, RB information, LCG information, or service target Identifier.

The QCI information generally indicates delay of a service, a packet loss rate, a resource usage priority, and the like.

For example, the service destination identification may be a destination ID. The service object identification typically indicates the type of a particular service message or service data.

The LCH information or LCG information is used to determine the LCH of the terminal, i.e., the LCH of the terminal communicating with another terminal. The LCG information is used to determine the LCG of the terminal, i.e., the LCG with which the terminal communicates with another terminal. The RB information is used to determine RBs of the terminal, i.e., RBs with which the terminal communicates with another terminal.

For example, the RB may include a Signaling Radio Bearer (SRB) and a Data Radio Bearer (DRB). Wherein the SRB is used to transmit control information between the terminal and another terminal. The DRB is used to transmit data between the terminal and another terminal.

For example, the logical channels of the terminal are LCH1 and LCH 2. The resource usage pattern corresponding to the service information may be: LCH1 corresponds to a dedicated resource pattern. LCH2 corresponds to a contention resource pattern.

In the embodiment of the present application, the resource usage mode corresponding to the service information may be understood as: and allowing the service corresponding to the service information transmitted by using the resource use mode. For example, if the service information is LCH information or LCG information, and the resource usage pattern is a dedicated resource pattern, the dedicated resource pattern corresponding to the LCH information or LCG information can be understood as: and allowing the service corresponding to the LCH information or the LCG information transmitted by using the special resource mode.

Step 102, the network device sends the service information and the resource usage mode corresponding to the service information to the terminal.

For example, in this embodiment of the present application, the network device may send the first configuration information to the terminal. The first configuration information carries service information and a resource usage mode corresponding to the service information. For example, the first configuration information may be a broadcast message or a dedicated Radio Resource Control (RRC) message.

For example, the network device may send a broadcast message or an RRC reconfiguration message to the terminal when sending the service information and the resource usage pattern corresponding to the service information. In the broadcast message or the RRC reconfiguration message, the configuration may be performed by the following examples a to C:

example a:

dedicated denotes a dedicated resource pattern, content resource denotes a contention resource pattern, and both denotes joint use of a dedicated resource and a contention resource pattern.

Alternatively, example B:

in addition, the logistic channel and LCID correspondence of example B is modified to DRB and DRB ID or QoS information and QCI, or LCGInfo and LCG ID, which may also be referred to as such. For example

And 103, the terminal acquires the service information and the resource use mode corresponding to the service information.

In an alternative implementation manner, the service information in step 103 and the resource usage pattern corresponding to the service information may be pre-stored in the terminal. When the service information, and the resource usage pattern corresponding to the service information, are pre-stored in the terminal, steps 101 and 102 may be omitted.

In another alternative implementation manner, the terminal may receive a sixth message from the network device in step 103. The sixth message includes a resource usage pattern corresponding to the service information. So that the terminal can obtain the service information and the resource usage mode corresponding to the service information.

Illustratively, the sixth message may be a broadcast message or dedicated signaling.

And step 104, the terminal transmits the service corresponding to the service information on the side link by using the resource using mode.

Illustratively, step 104 may be implemented by: and the terminal transmits the service corresponding to the service information on the side link by using the resource corresponding to the resource use mode.

It should be understood that, after the terminal acquires the service information and the resource usage pattern corresponding to the service information, the terminal transmits the service corresponding to the DRB or RB or LCH or LCG corresponding to the dedicated resource pattern using the dedicated resource when performing DRB or RB or LCH or LCG transmission corresponding to the dedicated resource pattern according to the resource usage pattern corresponding to the service information. And when performing DRB or LCH or LCG transmission corresponding to the competition resource mode, transmitting corresponding services on the DRB or RB or LCH or LCG corresponding to the competition resource mode by using the competition resources. And when performing DRB or LCH or LCG transmission corresponding to the mode of jointly using the dedicated resources and the contention resources, transmitting the service corresponding to the DRB or RB or LCH or LCG by using the dedicated resources and the contention resources.

For example, LCH1 corresponds to a dedicated resource mode and LCH2 corresponds to a contention resource mode. The terminal transmits traffic corresponding to LCH1 on the sidelink using the dedicated resource pattern. And the terminal transmits the service corresponding to the LCH2 on the sidelink by using a competition resource mode.

It should be understood that, in the embodiment of the present application, the service corresponding to the LCH refers to the service transmitted on the LCH. The service corresponding to the service target identifier refers to the service indicated by the service target identifier, and the service corresponding to the RB refers to the service transmitted on the RB. The service corresponding to the LCG refers to the service transmitted on the LCG.

In an alternative embodiment, as shown in fig. 7, the method provided in this embodiment further includes:

and 105, the terminal acquires the special resource distributed for the terminal.

For example, the terminal detects a Physical Downlink Control Channel (PDCCH) sent by the network device, and acquires information of available dedicated resources. I.e., Mode1 grants (grant) resources.

And step 106, the terminal multiplexes the service corresponding to the at least one LCH, the service corresponding to the at least one RB or the service corresponding to the at least one LCG associated with the dedicated resource mode on the dedicated resource.

Multiplexing (multiplex) refers to mapping a packet onto a certain resource. I.e. part of the bits of packet a may be mapped on resource a. Then, after the multiplexing is completed, the terminal transmits the multiplexed data (i.e. the partial bits of the data packet a) on the resource a.

Optionally, the terminal may further multiplex, on the dedicated resource, a service corresponding to the QCI associated with the dedicated resource mode, and multiplex, on the dedicated resource, a service corresponding to the service target identifier associated with the dedicated resource mode.

Step 107, if the dedicated resource further has a remaining resource, the terminal multiplexes a first service on the remaining resource, where the first service is a service corresponding to at least one LCH associated with the contention resource mode or a service corresponding to at least one RB or a service corresponding to at least one LCG, or the first service is a service corresponding to at least one LCH associated with the joint use of the dedicated resource and the contention resource mode or a service corresponding to at least one RB or a service corresponding to at least one LCG.

For example, taking the service information as LCH as an example, the terminal performs multiplexing transmission of data based on the received Mode1 grant resource. In the sidelink resource multiplexing process, the terminal maps the data on each corresponding LCH on the Mode1 grant resource based on each LCH allowing to use the Mode1 grant resource. After data multiplexing on each LCH, if the Mode1 grant resource still has a residual grant resource, the terminal can multiplex the data on the LCH transmitted by Mode2 to the residual grant resource for transmission.

For example, the services corresponding to at least one LCH associated with the dedicated resource mode are service 1 and service 2, and the services corresponding to at least one LCH associated with the contention resource mode are service 3 and service 4. Wherein, the size of the dedicated resource 1 is 500 bits, and if the size occupied by the service 1 and the service 2 multiplexed on the dedicated resource 1 is: 300 bit. The terminal may also multiplex service 3 and service 4 for transmission on the remaining resources (e.g., 200 bits) of the dedicated resource 1.

The embodiment of the application can effectively improve the utilization rate of the special resources by executing the steps 105 to 107.

Since any resource usage pattern may correspond to a plurality of LCHs or a plurality of RBs, priorities may be assigned to a plurality of LCHs or RBs corresponding to the same resource usage pattern for resource usage patterns corresponding to a plurality of LCHs or RBs. In an optional embodiment, the method provided in the embodiment of the present application further includes: the terminal determines a priority of a plurality of LCHs, a priority of a plurality of RBs, a priority of a plurality of QCIs, or a priority of a plurality of LCGs associated with the resource usage pattern. Therefore, the terminal can preferentially transmit the LCH with high priority or the RB with high priority or the QCI with high priority by using the resource utilization mode.

For example, in the embodiments of the present application, the terminal determines the priorities of the plurality of LCHs, the priorities of the plurality of RBs, the priorities of the plurality of QCIs, or the priorities of the plurality of LCGs associated with the dedicated resource mode. Thus, when the dedicated resource mode corresponds to a plurality of LCHs, RBs, QCIs, or LCGs, the terminal can preferentially transmit LCHs, RBs, QCIs, or LCGs having a high priority over the dedicated resource mode.

For example, in the embodiment of the present application, the terminal determines the priorities of the plurality of LCHs, the priorities of the plurality of RBs, the priorities of the plurality of QCIs, or the priorities of the plurality of LCGs associated with the contention resource mode. Thus, when the contention resource mode corresponds to a plurality of LCHs, RBs, QCIs, or LCGs, the terminal can preferentially transmit the LCH, RB, QCI, or LCG with a higher priority in the contention resource mode.

In an alternative implementation manner, the terminal determining the priorities of the plurality of LCHs, the priorities of the plurality of RBs, the priorities of the plurality of QCIs, or the priorities of the plurality of LCGs associated with the resource usage mode may be implemented by the following manner 1 or manner 2:

and in the mode1, the network equipment sends a seventh message to the terminal. Wherein the seventh message includes priorities of a plurality of LCHs, priorities of a plurality of RBs, priorities of a plurality of QCIs, or priorities of a plurality of LCGs corresponding to the resource usage pattern. Such that the terminal receives a seventh message from the network device to obtain priorities of the plurality of LCHs, or priorities of the plurality of RBs, or priorities of the plurality of QCIs corresponding to the resource usage pattern.

For example, the priorities of the LCHs corresponding to the dedicated resource patterns are: the priority of LCH1 is higher than that of LCH2, and the priority of LCH2 is higher than that of LCH 1.

The seventh message in the embodiment of the present application may be carried in the first configuration message.

And in the mode2, the terminal determines the priorities of a plurality of LCHs, a plurality of RBs, a plurality of QCIs or a plurality of LCGs corresponding to the resource use mode according to the service requirement.

It should be understood that when the resource usage pattern is a dedicated resource pattern, the resource usage pattern in the dedicated resource pattern alternatives 1 and 2 may be used to determine the priority of the LCHs, the priority of the RBs, the priority of the QCIs, or the priority of the LCGs to which the dedicated resource pattern corresponds. For the contention resource mode, the priorities of multiple LCHs corresponding to the joint use of dedicated resources and the contention resource mode, the priorities of multiple RBs, the priorities of multiple QCIs, or the priorities of multiple LCGs, the dedicated resource mode may be referred to, which is not limited in the embodiment of the present application.

The terminal may also obtain the contention resource in the process of requesting the dedicated resource from the network device and using the dedicated resource. As another embodiment of the present application, as shown in fig. 8, the method further includes:

step 108, the network device sends a first message to the terminal.

The first message is used for indicating the terminal to acquire the contention resource.

Optionally, the network device may send the first message to the terminal when allocating the dedicated resource to the terminal. The first message may also be used to indicate that contention resources are not used.

Illustratively, the network device indicates whether the terminal needs to continue using the contention resource when allocating the dedicated resource for the terminal. For example, if the network device determines that traffic transmission on all LCH/RB/LCGs of the terminal can use dedicated resource transmission, the network device may instruct the terminal not to use contention resources. That is, the first message is used to instruct the terminal not to acquire the contention resource. If the network equipment determines that the services on the part of LCH/RB/LCG of the terminal can not be transmitted by using the dedicated resources, the network equipment can indicate that the terminal needs to acquire the competitive resources. That is, the first message is used to instruct the terminal to acquire the contention resource.

Step 109, the terminal receives a first message from the network device.

Illustratively, when the first message indicates the terminal to acquire the contention resource, the terminal determines to acquire the contention resource. When the first message is that the contention resource is not used, the terminal may determine to stop acquiring the contention resource.

Steps 108 and 109 show that the terminal decides whether to acquire the contention resource based on the indication of the network device. In the actual process, the terminal can also autonomously determine whether to acquire the contention resources. Example procedures are shown in modes 3-5 below:

and 3, the terminal determines that the service transmitted by using the competition resource mode exists, and the terminal determines to acquire the competition resources. Or the terminal determines that no service transmitted by using the competition resource mode exists, and the terminal determines not to acquire the competition resources.

For example, the terminal determines that the dedicated resource cannot be used by a part of the LCHs or RBs according to the service information and the resource usage pattern corresponding to the service information, and then the terminal determines that the contention resource needs to be acquired.

And 4, the terminal determines that the competitive resources need to be acquired according to the service type of the service.

For example, if the terminal determines that the current service is a low-priority service, the terminal determines that the contention resource needs to be acquired. For example, if the terminal needs to transmit that the traffic in the current driving area is smooth, the terminal may determine to transmit in a resource competition manner without requesting to use a dedicated resource.

For example, if the terminal determines that the current service is a low-reliability service, the terminal determines that the contention resource needs to be acquired.

And 5, the terminal determines to acquire the competitive resource according to the service information and the resource use mode corresponding to the service information.

For example, the terminal determines to acquire the contention resource according to the service information and the resource usage pattern corresponding to the service information, determines the service on the LCH/RB/LCG using only the dedicated resource pattern, and determines the service on the LCH/RB/LCG using only the contention resource pattern. And using the service on the LCH/RB/LCG which jointly uses the dedicated resources and the competition resource mode. And determining whether to use the competitive resources according to the information.

In an alternative embodiment, as shown in fig. 9, the method provided in this embodiment further includes:

and step 110, when the first preset condition is met, the terminal determines to request the network equipment for the special resource.

Illustratively, the first preset condition includes any one or more of the following information: the service arrival of the dedicated resource mode transmission, the use conflict rate of the competitive resources is higher than a first threshold, or the moving speed of the terminal meets a second threshold.

For example, the terminal may determine that the service transmitted using the dedicated resource mode arrives according to the service information and the resource usage mode corresponding to the service information.

For example, higher layer triggered traffic of a terminal corresponds to dedicated resource requirements. The specific type of service corresponding to the request dedicated resource is pre-stored in the terminal. Such as a mapping or correspondence between pre-stored traffic QCI information and resource usage patterns. Or the terminal acquires from the broadcast message sent by the network equipment. For example, the broadcast message sent by the network device carries a corresponding relationship between the service type and the dedicated resource request, or a mapping relationship between the QCI information of the broadcast service and the resource usage mode.

It should be understood that the conflict rate of the usage of the contention resource refers to a ratio of a time period when the terminal does not successfully obtain the resource to a time T when the terminal performs channel sensing or application within the time T. Or the collision rate of the contention based resource also includes the probability or rate of data transmission failure when the terminal transmits data on the contended resource within a certain time.

The current moving speed of the terminal meets a second threshold. For example, above a second threshold, a network is requested to allocate configuration (Configured) grant specific resources, and below the second threshold, dynamic grant specific resources may be allocated. The dynamic grant refers to a dedicated resource dynamically allocated to the terminal by the network device, and the dedicated resource can be used by the terminal only in a time slot allocated to the terminal. The Configured grant refers to a dedicated resource allocated by the network to the terminal in a semi-static manner, and the dedicated resource can be used by the terminal for a long time.

The first threshold and the second threshold are not limited in the embodiment of the application and can be set according to requirements.

Illustratively, the terminal determines to request dedicated resources from the network device, and therefore, the RRC layer of the terminal triggers a Medium Access Control (MAC) layer of the terminal to initiate Random Access (RA) Access. And the terminal receives the random access response message sent by the network equipment.

Illustratively, the network device may allocate a dedicated preamble for the dedicated resource request to the terminal to accelerate the access success rate for the terminal of the dedicated resource request. Or the network device may allocate an independent preamble and Physical Random Access Channel (PRACH) resource set to the terminal requesting the dedicated resource, and the terminal preferentially selects the preamble and the PRACH resource from the PRACH resource set when initiating the RA.

And step 111, the terminal sends a second message to the network equipment. Wherein the second message comprises the first indication.

The first indication is used for requesting to allocate dedicated resources for the terminal, or the first indication is used for requesting to establish connection for the terminal.

Illustratively, the first indication includes any one or more of the following information: indicating a request for dedicated resources and/or contention resources; or, QoS requirement information of the service on the sidelink; or, transmission mode information of the sidelink; or, a resource usage pattern; or, using the traffic information of the contention resource mode on the sidelink.

Illustratively, the QoS requirement information of the traffic to be transmitted includes any one or more of the following: QCI information, or LCH information, or LCG information, or RB information of a service to be transmitted.

Alternatively, the second message may be message 3(MSG3) in the random access procedure of the terminal, for example. The first indication may be a cause value. For example, the transmission mode information of the sidelink may be unicast transmission, highly reliable unicast or multicast transmission.

Illustratively, after the terminal sends the second message, the terminal may receive a random access message 4 from the network device, confirming that the random access procedure was successfully completed.

Optionally, the second message may also be an RRC message, for another example. The terminal may also indicate to request dedicated resources through a dedicated RRC message after the RRC connection setup is completed. That is, in the random access message, or RRC establishment request message, the terminal does not explicitly indicate that the RRC connection is established for the dedicated resource request.

Or, in yet another example, the terminal may carry the request for requesting allocation of the dedicated resource for the terminal in the following signaling manner:

A) and requesting dedicated resources through a specific Scheduling Request (SR) resource configured by the network.

That is, the terminal receives resource request configuration information (SR configuration information) sent by the network device, where the resource request configuration information includes SR resources configured for requesting dedicated resources. When the terminal triggers to request the dedicated resources, the terminal sends an SR request through the configured SR resources requesting the dedicated resources so as to indicate the network equipment that the terminal needs to request the dedicated resources.

Illustratively, the dedicated resources subsequently allocated by the network device depend on Buffer Status Report (BSR) information of sidelink sent by the terminal. The trigger condition for SR request transmission is that the terminal needs to request dedicated resources.

B) And requesting the special resource by a mode of sending the BSR.

Illustratively, the terminal sends the BSR with special indication information requesting dedicated resources to indicate the network device to allocate dedicated resources for the terminal.

C) The terminal explicitly instructs the network device to allocate dedicated resources by sending an RRC message, e.g. a dedicated resource request message. However, the resource amount of the dedicated resource allocated to the terminal is allocated according to the BSR information of sidelink transmitted by the terminal.

Step 112, the network device receives a second message from the terminal.

It is to be understood that, if the first indication is for requesting allocation of dedicated resources for the terminal, the network device allocates dedicated resources for the terminal, via step 112. If the first indication is for requesting a connection to be established for the terminal. And after the RRC connection is established between the network equipment and the terminal, the RRC connection is established for the terminal. I.e. after step 112, the terminal may acquire dedicated resources in step 105.

It should be noted that, steps 110 to 112 in the embodiment of the present application may be executed as a separate embodiment, that is, when the terminal meets the first preset condition, the terminal may actively request the network device to allocate a dedicated resource. Further, optionally, when step 110 to step 112 are taken as separate embodiments, the embodiments may further include: step 101-step 109 and step 113-step 117.

In the process that the terminal uses the dedicated resource and the contention resource for service transmission, in order to better let the network device know about the actual resource transmission situation, the terminal may report the resource usage situation, as shown in fig. 10, where the method provided in the embodiment of the present application further includes: and step 113, the terminal sends a data volume report to the network equipment.

Here, specific contents in the data amount report may refer to the specific description of any one of examples 1 to 5 below.

Example 1, a data volume report, comprising: at least one of an amount of data transmitted using the dedicated resource mode and an amount of data transmitted using the contention resource mode.

For example, data volume reports, include: the amount of data transmitted using the dedicated resource pattern. Alternatively, the data volume report includes: the amount of data transmitted using the contention resource mode. Or a data volume report, comprising: the amount of data transmitted using the dedicated resource mode and the amount of data transmitted using the contention resource mode.

Example 2, data volume reporting, comprising: and caching data amount information. Wherein the cache data volume information comprises at least one of: the method comprises the steps of configuring cache data volume information of LCH, LCG or RB using a dedicated resource mode, configuring cache data volume information of LCH, LCG or RB using a competition resource mode, and configuring cache data volume information of LCH, LCG or RB using a dedicated resource mode and a competition resource mode jointly.

Example 3, data volume reporting, comprising: and configuring data amount information of contention resources used by the LCH, the LCG or the RB using the dedicated resource mode.

For example, the network device configures the LCH1 to use a dedicated resource pattern. However, in the actual process, the terminal uses the contention resource mode to transmit the service corresponding to the LCH1 on the contention resource, so the terminal can send the data volume information of the contention resource used by the LCH1 to the network device.

Example 4, data volume reporting, comprising: and configuring data volume information of contention resources used by the LCH or the LCG or the RB which jointly use the dedicated resources and the contention resource mode.

For example, the network device configures the LCH2 to use a dedicated resource pattern in conjunction with a contention resource pattern. However, in the actual process, the terminal jointly uses the dedicated resource mode and the contention resource mode to transmit the service corresponding to the LCH1 on the contention resource and the dedicated resource, so that the terminal can send the data volume information of the contention resource used by the LCH2 to the network device.

Example 5, the data volume report, comprising: a relation between the amount of padding (padding) data transmitted on the sidelink and the fifth threshold, or data amount information of the amount of padding data.

The padding data amount refers to the invalid bits. Not the true traffic data bits.

For example, the relationship between the amount of padding data and the fifth threshold may be: the amount of padding data is above a fifth threshold. Or the amount of padding data is below a fifth threshold. For example, 1bit is used to represent the relationship between the amount of padding data and the fifth threshold. A "1" indicates above the fifth threshold. A "0" indicates being below the fifth threshold.

Exemplary, data volume reports include: padding (padding) the relation between the data amount and the fifth threshold in the first preset time, wherein the data amount is sent on the sidelink.

Illustratively, the terminal may use data amount information indicating the amount of padding data using multiple bits. The amount of padding bits sent by the UE since the last BSR report.

Step 114, the network device receives the data volume report from the terminal.

For the report of the cache data amount corresponding to the LCH or LCG that can use the dedicated resources and the contention resources at the same time, the report may be reported based on the following rules:

the network device configures the LCH or LCG which can jointly use the dedicated resources and the competitive resources and can respectively use the dedicated resources and the competitive resources to transmit the data volume information of the service. For example, the data amount information of the service transmitted by using the dedicated resource is configured to be a proportion a, and the proportion of using the contention resource is configured to be 1-a. For example, if the terminal currently has data with a size of 100 bytes to be transmitted for the LCH or LCG, the terminal transmits the data of 40 bytes using the dedicated resource and transmits the data of another 60 bytes using the contention resource. Therefore, when the terminal performs BSR reporting, for the LCH or LCG, the data amount of the byte reported to the network device 40by the terminal requests to use the dedicated resource mode for transmission. Alternatively, the data amount of the 60 bytes can be reported requesting transmission using the contention resource mode.

Alternatively, the ratio of dedicated resources to be used is configured as a, and the ratio of contention resources to be used is configured as b. Then, the terminal determines the data amount corresponding to the LCH or LCG that can be included in the reported BSR according to the service information of the dedicated resources and the contention resources that can be used by the network, respectively.

Or, the terminal determines or prestores the information of the dedicated resource and the contention resource transmission data which can be used respectively in the terminal. For example, the terminal determines itself or pre-stores in the terminal the ratio a of the available dedicated resources, thereby configuring the ratio of the used contention resources as 1-a. Or the proportion of using the dedicated resources is configured to be a, and the proportion of using the competitive resources is configured to be b. Then, when reporting the BSR buffer data volume report, the terminal determines the data volume corresponding to the LCH or LCG that can be included in the reported BSR according to the quantity information determined above.

Optionally, the terminal may report the information of the data transmitted by the dedicated resources and the contention resources determined by the terminal to the network device, so as to assist the network device to allocate an appropriate amount of resources.

In an alternative implementation manner, step 113 in the embodiment of the present application may be implemented by: and when the second preset condition is met, the terminal sends a data volume report to the network equipment.

Wherein the second preset condition comprises any one or more of the following information: the success rate of the terminal for acquiring the competition resources is higher than a third threshold, the terminal determines that the service needing to be transmitted by using the special resource mode exists, the preset period is short, and the filling data volume of the competition resources or the special resources on the side chain link is higher than the third threshold.

For example, in a process of performing data transmission by a terminal, a data amount transmitted on a contention resource may have a certain volatility, for example, the contention resource is acquired more chances within a certain time, and then the data amount transmitted on the contention resource is larger, then: when the success rate of the terminal for acquiring the contention resource is higher than the third threshold, the terminal sends a data volume report to the network device, which may assist the network device to adjust the allocation of the dedicated resource, or trigger the network device to stop the allocation of the dedicated resource. In the embodiment of the present application, the preset period is not limited.

Optionally, after receiving the data volume report, the network device may determine to cancel the dedicated resource allocated to the terminal, and send a reconfiguration message to the terminal, where the reconfiguration message is used to cancel the dedicated resource mode configured for the terminal, for example, to reconfigure a certain LCH, LCG, or RB from an original dedicated resource mode to a contention resource mode, or to reconfigure a certain LCH, LCG, or RB from an original mode in which the dedicated resource and the contention resource are jointly used to a contention resource mode. Alternatively, the network device configures an LCH or RB or LCG that previously could use dedicated resources in conjunction with contention resources to use contention resources. Alternatively, the network device may reconfigure a certain LCH or LCG or DRB, for example, configure a certain LCH or LCG or DRB to only use dedicated resources, and reduce the LCH or LCG or DRB using contention resources.

For example, the network device may determine whether to cancel the dedicated resource according to the amount of data transmitted through the contention resource in the data amount report. For example, if the amount of data that can be sent by the terminal through the contention resource is higher than a certain value, the network device may determine that the terminal can currently obtain the contention resource more easily.

In addition, the terminal determines that the current competitive resource amount is large, and can acquire the competitive resource with high probability, and then can actively request to abandon the use of the special resource. That is, if the above condition is satisfied, the terminal directly sends a cell request to cancel the dedicated resource allocation. Or the terminal directly sends a message request to modify the resource usage mode of one or more LCH/LCG/DRB into a dedicated resource, and the like.

In an alternative embodiment, as shown in fig. 11, the method provided in this embodiment further includes:

step 115, the network device sends a third message to the terminal. Wherein the third message is used for indicating that the resource usage mode of the first LCH or the first LCG or the first RB is switched from the first resource mode to the contention resource mode; or the third message is used for indicating the resource use mode of the terminal to be switched from the first resource mode to the competition resource mode.

Wherein the first resource pattern comprises: the dedicated resources are used in combination with either one of the contention resource mode and the dedicated resource mode.

And step 116, the terminal receives a third message sent by the network device.

Step 117, the terminal determines to cancel the buffer status report. Or, the terminal determines to cancel the buffer status report triggered by the first LCH, the first LCG or the first RB. Or, the terminal determines that the buffer status report does not include the buffer data volume of the logical channel group corresponding to the first LCH, the first LCG, or the first RB. Or the terminal cancels the resource request triggered by the buffer status report, wherein the resource request comprises an SR or a random access process initiated for the resource request.

Illustratively, the buffer status report is used to indicate the amount of data to be sent in the terminal.

For example, when the terminal currently uses the first LCH, the first LCG, or the first RB of the dedicated resource mode, or the first LCH, the first LCG, or the first RB of the combined dedicated resource and contention resource mode triggers the report of the buffer status report, the terminal receives a third message indicating to switch the resource usage mode of the first LCH, the first LCG, or the first RB from the first resource mode to the contention resource mode, or a third message indicating to switch the resource usage mode of the terminal from the first resource mode to the contention resource mode, and at this time, the terminal cancels the report of the buffer status report triggered by the first LCH, the first LCG, or the first RB.

Optionally, if the triggered buffer status report reports that the SR has been triggered or the random access procedure has been triggered, the terminal should cancel the triggered SR or the terminal should stop the triggered random access procedure.

When the terminal triggers an SR, the SR is in a "Pending" state, which means that the terminal prepares but has not sent the SR to the network device. However, when the terminal has assembled a medium access control protocol data unit (MAC PDU), and the MAC PDU includes a recently triggered buffer status report control unit, or resources provided by the uplink grant can accommodate all Pending data, the SR in the "Pending" state is cancelled, and the prohibit timer also stops.

Optionally, in order to save the use of dedicated resources as much as possible, when a second preset condition for reporting the data volume report is met, if the terminal has already acquired resources of certain contention resources (for example, the current timeslot or one or more future timeslots), the terminal should not include the data volume sent on the contention resources in the data volume report when reporting the data volume report.

For example, in the case where the contention resource is not acquired, the terminal should report the amount of data to be sent to the network device for requesting the dedicated resource of 100 bits. In the case of acquiring the contention resource, taking the size of the contention resource as 60 bits as an example, the terminal should report the data volume sent to the network device to request the dedicated resource of 40 bits.

As another embodiment of the present application, when a terminal uses a dedicated resource and a contention resource mode to transmit a service on a sidelink, a method provided in an embodiment of the present application further includes: the terminal sends a fourth message to the network device so that the network device receives the fourth message from the terminal. The fourth message is used for indicating the data volume information of the service transmitted by the terminal in the dedicated resource mode and/or the data volume information of the service transmitted by the terminal in the contention resource mode.

For example, the terminal determines that the data amount of the service transmitted using the dedicated resource mode is 50% of the total service data amount. Or the terminal determines that the data amount of the traffic data transmitted using the contention resource mode is 50% of the total traffic data amount. Here, the total traffic data amount refers to a total data amount of one or more LCH/LCG/RB of the terminal currently to be transmitted.

Or, as another embodiment of the present application, when the terminal uses the dedicated resource and the contention resource mode to transmit the service on the sidelink, the method provided in the embodiment of the present application further includes: the network device sends an eighth message to the terminal so that the terminal receives the eighth message from the network device. Wherein the eighth message is used for indicating the data volume information of the service transmitted by using the dedicated resource mode and/or the determined data volume information of the service transmitted by using the contention resource mode.

In a process that a terminal uses a dedicated resource mode or a contention resource mode to transmit a service on an sidelink, the terminal may adjust to use the dedicated resource mode or the contention resource mode to transmit the service on the sidelink, and the method provided in the embodiment of the present application further includes: the terminal controls the dedicated resource mode or the competitive resource mode to transmit the service on the side link.

Illustratively, the terminal controls the dedicated resource mode or the contention resource mode to transmit the traffic on the sidelink, which may be implemented as follows: the terminal preferentially uses a dedicated resource mode or a competitive resource mode to transmit the service on the side link. Alternatively, the terminal preferentially allocates power on the dedicated resource mode. Or, the terminal performs proportional power allocation on the traffic transmitted on the sidelink by using the dedicated resource mode and the contention resource mode respectively.

In the process of performing service transmission by using dedicated resources and contention resources jointly by a terminal, since the network device does not know the contention resources selected by the terminal, there may be a case where the dedicated resources allocated by the network device to the terminal and the contention resources obtained by the terminal are in the same TTI. In an optional implementation manner, the terminal controls the dedicated resource mode or the contention resource mode to transmit the service on the sidelink when a third preset condition is met.

Wherein the third preset condition comprises any one or more of the following information:

the condition 1, the dedicated resource allocated to the terminal and the contention resource of the terminal have the same time slot.

For example, the dedicated resource allocated by the network device for the terminal and the contention resource of the terminal are both located in slot 1. This is due to the fact that even though the dedicated resources and the contention resources are located on different carriers or BWPs, there are different maximum transmit powers on different carriers or BWPs in the same slot. There are also power limited situations that occur. In the case of limited terminal power, the dedicated resources and the contention resources are insufficient when they occur in the same time slot.

The condition 2, the dedicated resource and the contention resource are located in the same carrier, and the slot (slot) of the dedicated resource and the slot of the contention resource are the same.

For example, the dedicated resource allocated to the terminal and the contention resource of the terminal are both located in carrier 1, and the dedicated resource and the contention resource of the terminal are both located in slot 1.

Condition 3, there is a partial overlap of the time slots of the contention and dedicated resources.

For example, the contention resources are located at slot 1, slot 2 and slot 3, and the dedicated resources are located at slot 2 and slot 3.

And in the condition 4, the time for overlapping the time slots of the competition resources and the special resources is greater than a fourth threshold.

For example, the fourth threshold may be a predetermined character (symbol) length.

And 5, the transmitting power of the terminal on the competition resource and the special resource reaches a power threshold value.

If the service target identifiers are different, the terminal cannot transmit the dedicated resources and the contention resources in the same carrier (carrier) and the same Transmission Time Interval (TTI) at the same Time, and at this Time, the terminal may select the dedicated resources for Transmission according to the service target identifiers, or select the contention resources for Transmission. Illustratively, in the case that a third preset condition is met, the terminal preferentially uses the dedicated resource mode or the contention resource mode to transmit traffic on the sidelink, including: and the terminal determines to use a dedicated resource mode or a competitive resource mode to transmit the service on the side link according to the service target identifier. For example, a high speed closure event such as V2X lower front can be identified by an object ID of 1; dedicated resources may be preferentially used; congestion 2 km ahead may be indicated as severe by another target ID 2. This available contention resource. And another object ID3 indicates an indication that the vehicle 1 is sending warning information to the vehicle, which makes available dedicated resources.

In order to enable the dedicated resource allocated by the network device to the terminal and the contention resource of the terminal to be located in different time slots, in an optional embodiment, the method provided in this embodiment further includes: the terminal sends information of the contended resource or a time slot of the contended resource to the network device. So that the network device receives information of the contended resource from the terminal or a time slot of the contended resource. Thereby enabling the network device to place the allocated dedicated resources in a different time slot than the contention resources selected by the terminal.

The dedicated resources and the contention resources of the terminal are located in different time slots, and the terminal can transmit data in different time slots without wasting resources. However, if the power of the terminal is not limited, contention resources and dedicated resources exist in the same time slot, which is more beneficial for the terminal to transmit data quickly and has a higher data transmission rate.

In an optional embodiment, the method provided in the embodiment of the present application further includes: when the number of collisions between the contention resource and the dedicated resource is higher than the fourth threshold, the terminal sends the number of collisions between the contention resource and the dedicated resource to the network device, where the number of collisions between the contention resource and the dedicated resource received by the network device from the terminal is higher than the fourth threshold.

The number of collisions between the contention resource and the dedicated resource refers to the number of times that the contention resource and the dedicated resource appear in the same time slot or overlap the time slots within a certain time.

Illustratively, when the number of collisions between the contention resource and the dedicated resource within the preset time is higher than a fourth threshold, the terminal sends, to the network device, that the number of collisions between the contention resource and the dedicated resource within the preset time is higher than the fourth threshold.

For a multi-carrier or multi-Part Bandwidth (BWP) scenario, the network device may explicitly instruct the terminal to select a carrier or BWP that contends for the resources, and then the network device schedules dedicated resources for the terminal on other carriers than the designated carrier or BWP. In an optional implementation manner, the method provided in the embodiment of the present application further includes: the network device transmits information of a carrier associated with the contention resource pattern or information of the BWP to the terminal. Such that the terminal receives information of carriers associated with the contention resource mode or information of BWP from the network device. This may enable the terminal to select contention resources on information of carriers or information of BWPs associated with the contention resource pattern.

The information of the carrier may be an identifier of the carrier. The information of the BWP may be an identification of the BWP.

For example, if the network device instructs the terminal to select contention resources on carrier 2, the network device may allocate dedicated resources for the terminal on carrier 3. I.e. the terminal may select contention resources on carrier 2.

Of course, for the same carrier, the network device may further indicate information of a carrier or BWP associated with the contention resource mode, and acquire the first time period of the contention resource on the carrier or BWP indicated by the information of the carrier. The network device may then allocate dedicated resources for the terminal on the carrier or BWP outside the first time period.

In an optional implementation manner, the method provided in the embodiment of the present application further includes: the terminal sends the network device the expected resource usage pattern on the carrier or BWP. Such that the terminal receives a desired resource usage pattern on the carrier or BWP from the terminal.

For example, the terminal may transmit the information of the carrier or the information of the BWP and the resource usage pattern associated with the information of the carrier or the information of the BWP to the network device.

The above-mentioned scheme of the embodiment of the present application is introduced mainly from the perspective of interaction between network elements.
