With the development of terminals and the infrastructure construction of NR cellular networks, terminals that only support LTE (Long Term Evolution) sidelink may also support NR Uu. In the future, even if the NR sidelink is standardized to form a product, in order to perform interconnection and interworking with a terminal that only supports LTE sidelink in the previous stage, terminals that support NR sidelink and LTE sidelink at the same time are required until the terminal that only supports LTE sidelink completely disappears, so the terminal in the later stage may be: firstly, supporting LTE sidelink and NR Uu; and secondly, simultaneously supporting NR sidelink, LTE sidelink and NR Uu. In this process, with the gradual reduction of the coverage of the LTE cellular network, the following problems are caused:

2) under the condition of single network coverage of an NR cellular network and a terminal supporting LTE sidelink and NR sidelink, when BSM (Basic security gateway) service is transmitted, LTE sidelink needs to be used.

Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
In order that those skilled in the art will be better able to understand the embodiments of the present invention, the following explanation is first made.
Standardization of LTE V2X by 3GPP has been completed. The 3GPP protocol determines that there are two ways LTE V2X to communicate. The first mode can carry out direct communication between nodes through a PC5 interface; and in the second mode, the communication can be carried out through an LTE-Uu interface. The Mode-one communication is adopted, and the modes can be divided into a network centralized control Mode 3 Mode and a distributed control Mode 4 Mode according to the control Mode of the network to the nodes.
V2X communication shares a carrier with cellular communication or uses a dedicated carrier. In the coverage of E-UTRAN (Evolved UMTS Terrestrial Radio Access Network), the V2X communication node determines whether the node uses the Mode 3 Mode or the Mode 4 Mode according to configuration Information in the received signaling, where the specific signaling includes SIB21(System Information Block21, System message Block 21) and RRC (Radio Resource Control) configuration message.
In the case that the V2X communication node uses the Mode 3 Mode, a UE (User Equipment) may report a message to notify the base station of the following information: the information includes longitude and latitude geographic position information, service sending period, maximum packet size of service packet, service priority and the like. An eNB (evolved Node B, evolved base station) notifies a V2X communication Node sidelink of resources required for transmitting control information and data information through DCI Format 5A for a V2X communication Node communicating on a PC5 interface.
NR Uu has already been standardized in 3GPP, but standardization work for NR sidelink supporting NR V2X has not yet started, and the infrastructure related to NR cellular networks is also under construction, and it is imperative that during the process of expanding coverage from hot-spot coverage by NR cellular networks, it will coexist with LTE cellular networks for some time, while development and replacement of automotive and road infrastructure is much slower compared to the rapid change of mobile communications. That is, the existing front-mounted vehicle-mounted terminal and roadside terminal supporting LTE sidelink exist all the time before the vehicle is scrapped or the roadside equipment is scrapped. Therefore, in order to perform interconnection with a terminal which only supports LTE sidelink in the previous period, terminals which support NR sidelink and LTE sidelink at the same time are required until the terminal which only supports LTE sidelink completely disappears.
Since the terminal at the later stage may be: firstly, supporting LTE sidelink and NR Uu; and secondly, simultaneously supporting NR sidelink, LTE sidelink and NR Uu. Therefore, when the terminal performs the scheduling of the data transmission resources of the direct link between the terminals, the terminal processing is complex, the signaling overhead of the network is large, and the system performance is poor, which becomes a problem to be solved.
Based on this, as shown in fig. 1, an embodiment of the present invention provides a resource scheduling method, which is applied to a terminal, and includes:
step 101, receiving downlink control information transmitted by a first base station supporting an nth generation mobile communication technology.
Preferably, the nth generation mobile communication technology specifically refers to 5G NR technology.
Here, the downlink control information may be represented by DCI.
And step 102, scheduling direct link transmission between terminals based on the Mth generation mobile communication technology according to the downlink control information.
Preferably, the direct link between the terminals of the mth generation mobile communication technology is LTE sidelink.
In this embodiment, the terminal performing the above steps is a resource scheduling allocation terminal, which is a Mode 3 terminal for LTE sidelink.
For example, in the case that the NR cellular network and the LTE cellular network coexist, the Mode 3 terminal schedules LTE sidelink transmission through DCI scheduling signaling sent by the base station supporting the 5G NR technology. That is, the Mode 3 terminal accepts the scheduling of the base station supporting the 5G NR technology, and does not accept the scheduling of the base station supporting the LTE technology, thereby reducing the terminal processing complexity and the network signaling overhead; under the condition that the system is under the single coverage of the NR cellular network, when the BSM service is sent, because the Mode 3 terminal receives the scheduling of the base station supporting the 5G NR technology, the pre-configured resource pool does not need to be used, and the system performance can be improved.
The resource scheduling method of the embodiment of the invention receives downlink control information sent by a first base station supporting the Nth generation mobile communication technology; and scheduling the data transmission of the direct link between the terminals based on the Mth generation mobile communication technology according to the downlink control information, so that the terminal can reduce the processing complexity of the terminal and the signaling overhead of a network and improve the system performance when scheduling the data transmission resources of the direct link between the terminals.
Preferably, the nth generation mobile communication technology and the mth generation mobile communication technology are not long term evolution LTE at the same time.
Further, scheduling, according to the downlink control information, direct link transmission between terminals based on an mth generation mobile communication technology, including:
and scheduling the direct link transmission between the terminals based on the Mth generation mobile communication technology under the condition that the target scheduling object indicated by the downlink control information is the direct link between the terminals based on the Mth generation mobile communication technology.
Further, before receiving downlink control information transmitted by a first base station supporting an nth generation mobile communication technology, the method further includes:
receiving system information and/or configuration information sent by the first base station or a second base station or a third-party entity supporting the Mth-generation mobile communication technology;
and determining the terminal as a resource scheduling distribution terminal according to the system information and/or the configuration information.
Here, the configuration information may include radio resource control RRC configuration information.
It should be noted that the terminal determines itself to allocate the terminal for resource scheduling, that is, the Mode 3 terminal, which indicates that the terminal needs the base station as a control center to assist the terminal in resource scheduling when the terminal performs direct communication between nodes.
As a preferred implementation manner, after determining that the terminal is a resource scheduling allocation terminal according to the system information and/or the configuration information sent by the second base station or the third party entity, the method further includes:
and determining the base station of the terminal which accepts the resource scheduling as the first base station.
Here, for example, if the system information and/or the configuration information is sent by the second base station supporting the LTE technology, then, in a case that the system is in dual-network coverage of the NR cellular network and the LTE cellular network, the second base station supporting the LTE technology may participate in scheduling of the transmission resource pool of the LTE sidelink, and if the base station that the subsequent terminal receives the resource scheduling is the first base station supporting the NR technology and is not the second base station supporting the LTE technology, the base station that the terminal subsequently receives the resource scheduling needs to be notified as the first base station supporting the NR technology.
Specifically, determining that the base station that the terminal receives the resource scheduling is the first base station includes:
and determining the base station of the terminal receiving the resource scheduling as the first base station through at least one of terminal pre-configuration, notification by the second base station, notification by the first base station and notification by a third party entity.
It should be noted that the terminal pre-configuration specifically refers to factory configuration of the terminal.
Here, the third party entity may include, but is not limited to: traffic management center, high in the clouds server.
Further, before receiving downlink control information transmitted by a first base station supporting an nth generation mobile communication technology, the method further includes:
sending a resource scheduling request to the first base station, the resource scheduling request comprising: service attribute information, or including: service attribute information and terminal location information.
In this embodiment, the terminal sends a resource scheduling request to the first base station, which indicates that the terminal currently has a resource scheduling requirement.
Here, the service attribute information includes at least one of: the size of the service packet, the sending period of the service packet, the service priority and the like.
The terminal location information may include, but is not limited to: and the geographic position information of the latitude and longitude where the terminal is located.
Further, before receiving downlink control information transmitted by a first base station supporting an nth generation mobile communication technology, the method further includes:
monitoring a channel on which the downlink control information is transmitted.
Here, the purpose of monitoring the channel on which the downlink control information is transmitted is to know whether the downlink control information is transmitted.
Further, the method further comprises:
determining a target scheduling object of the downlink control information.
Specifically, the determining the target scheduling object of the downlink control information includes:
determining a target scheduling object of the downlink control information through at least one of a service type which is interacted by a terminal currently, a scheduling request type of the terminal in a preset time, a resource scheduling type of the terminal, an instruction of the first base station to a scheduling object received by the terminal, an instruction of a second base station supporting the Mth generation mobile communication technology to the scheduling object received by the terminal, the terminal based on the downlink control information, the terminal based on other downlink control information except the downlink control information, and a preset format decoding mode of the downlink control information by the terminal.
In the following, based on the coexistence of the NR cellular network and the LTE cellular network, how to determine the target scheduling object of the downlink control information in the above manner is illustrated.
Firstly, through the service type mode that the terminal is currently interacting
For example, if the service type currently being interacted is a basic security service, the target scheduling object is an LTE sidelink; if the type of the currently interacting service is a cooperative decision service with ultra-low time delay and high reliability requirement, the target scheduling object is NR sidelink.
Secondly, scheduling request type mode of the terminal in preset time
For example, when the scheduling request type of the terminal is LTE sidelink at the time closest to the reception of the current downlink control information, the target scheduling target is LTE sidelink.
Thirdly, through the resource scheduling type mode of the terminal
For example, if the terminal on NR sidelink is a terminal selected from autonomous resources, i.e. similar to Mode 4 terminal, and the terminal on LTE sidelink is a terminal allocated for resource scheduling, i.e. Mode 3 terminal, the target scheduling object is LTE sidelink.

In this embodiment, the purpose of exchanging the transmission resource pool and/or the resource scheduling information with the second base station is to prevent the second base station supporting the mth generation mobile communication technology and the first base station supporting the nth generation mobile communication technology from being able to allocate resources and causing resource collision.
Here, it is illustrated as an example that, when the system is in dual-network coverage of an NR cellular network and an LTE cellular network, and the terminal supports LTE sidelink, the second base station supporting the LTE technology participates in resource scheduling for the Mode 3 terminal supporting LTE sidelink, so that it is necessary for the first base station supporting the NR technology to negotiate resource allocation of LTE sidelink with the second base station supporting LTE technology, so as to achieve the purpose of reasonably allocating resources of LTE sidelink.

According to the resource scheduling method provided by the embodiment of the invention, the downlink control information is sent to the terminal, so that when the terminal performs the scheduling of the direct link data transmission resources between the terminals, the terminal processing complexity and the network signaling overhead can be reduced, and the system performance can be improved.
As shown in fig. 4, an embodiment of the present invention further provides a resource scheduling method, which is applied to a network device, where the network device is a first base station supporting an nth generation mobile communication technology, and the method includes:
step 401, executing a preset operation on a terminal to enable the terminal to be a terminal selected by an autonomous resource.
It should be noted that the first base station of the implementation subject of the present embodiment performs communication interaction with the terminal of the implementation subject of the method shown in fig. 2.
Here, the first base station performs a preset operation on the terminal, so that the terminal is a terminal selected by an autonomous resource, that is, a terminal similar to Mode 4, and the terminal selected by the autonomous resource performs autonomous selection scheduling on a transmission resource pool of a direct link between terminals based on an mth generation mobile communication technology.
Here, preferably, the nth generation mobile communication technology specifically refers to a 5G NR technology.
Preferably, the direct link between the terminals of the mth generation mobile communication technology is LTE sidelink.
According to the resource scheduling method provided by the embodiment of the invention, the terminal is the terminal selected by the autonomous resource by executing the preset operation on the terminal, so that the terminal can use the resource pool configured by the network instead of the resource pool pre-configured by the terminal when the terminal performs the scheduling of the data transmission resource of the direct link between the terminals, and the system performance is improved.
Further, the terminal performs preset operations, including:
sending a system message to a terminal, the system message comprising: and on the basis of a transmission resource pool of a direct link between terminals of the Mth generation mobile communication technology, the terminals become terminals for autonomous resource selection.
Here, since the system message includes: the terminal can acquire the transmission resource pool of the direct link between the terminals based on the Mth generation mobile communication technology, and the terminal is determined as the terminal with autonomous resource selection.
Further, executing preset operation on the terminal, including:
the terminal is configured as a terminal for autonomous resource selection.
Here, the first base station configures the terminal as a terminal for autonomous resource selection by establishing a connection with the terminal.
According to the resource scheduling method provided by the embodiment of the invention, the terminal is the terminal selected by the autonomous resource by executing the preset operation on the terminal, so that the terminal can use the resource pool configured by the network instead of the resource pool pre-configured by the terminal when the terminal performs the scheduling of the data transmission resource of the direct link between the terminals, and the system performance is improved.
Here, the implementation process of the resource scheduling method of the present invention is specifically described with reference to an example for a scenario where an NR cellular network and an LTE cellular network coexist in a dual network.
In one example, the steps of the resource scheduling method of the present invention include:
step S11, the second base station supporting LTE technology sends system information and configuration information to the terminal;
step S12, the terminal determines the terminal as LTE sidelink Mode 3 terminal according to the system message and the configuration message sent by the second base station;
step S13, the terminal learns the resource scheduling of the first base station which subsequently receives the support NR technology;
specifically, the notification may be at least one of a terminal pre-configuration, a notification by the second base station, a notification by the first base station, and a notification by a third party entity.
Step S14, the terminal reports the resource scheduling request of the terminal to the first base station;
here, the resource scheduling request includes service attribute information, or includes: service attribute information and terminal location information.
In addition, the terminal may report the resource scheduling request and the auxiliary information of the terminal to the first base station; the resource scheduling request comprises service attribute information, and the auxiliary information comprises terminal position information.
Step S15, the first base station negotiates with the second base station about the resource allocation of LTE sidelink.
It should be noted that, when the system is in dual-network coverage of the NR cellular network and the LTE cellular network and the terminal supports LTE sidelink, the second base station supporting LTE technology participates in resource scheduling for the Mode 3 terminal supporting LTE sidelink, so that it is necessary for the first base station supporting NR technology to negotiate resource allocation of LTE sidelink with the second base station supporting LTE technology, so as to prevent resource collision when both the second base station supporting LTE technology and the first base station supporting NR technology can allocate resources.
The purpose of reasonably distributing the LTE sidelink resources is achieved.
However, when the system is under the coverage of a single network of an NR cellular network and the terminal supports LTE sidelink, the first base station supporting NR technology does not need to negotiate the resource allocation of LTE sidelink with the second base station supporting LTE technology.
Step S16, the first base station sends DCI scheduling signaling to the terminal;
wherein, the DCI scheduling signaling includes all information in the DCI format 5A.
Step S17, the terminal schedules LTE sidelink transmission according to the DCI scheduling signaling.
Specifically, the terminal schedules the LTE sidelink transmission according to the content of the indication of the DCI scheduling signaling.
It should be noted that, when the terminal is a dual-mode terminal, that is, a dual-mode terminal supporting LTE sidelink and NR sidelink, it is necessary to increase the differentiation of DCI scheduling objects, so that the terminal can identify whether the DCI scheduling signaling is used for scheduling LTE sidelink transmission.
In particular, the distinguishing means may be one or more combinations of the following occurrences.
1) By the service type mode that the terminal is currently interacting
For example, if the service type currently being interacted is a basic security service, the target scheduling object is an LTE sidelink; if the type of the currently interacting service is a cooperative decision service with ultra-low time delay and high reliability requirement, the target scheduling object is NR sidelink.
2) Through the scheduling request type mode of the terminal in the preset time
For example, when the scheduling request type of the terminal is LTE sidelink at the time closest to the reception of the current downlink control information, the target scheduling target is LTE sidelink.
3) Resource scheduling type mode through terminal
For example, if the terminal on NR sidelink is a terminal selected from autonomous resources, i.e. similar to Mode 4 terminal, and the terminal on LTE sidelink is a terminal allocated for resource scheduling, i.e. Mode 3 terminal, the target scheduling object is LTE sidelink.
4) Indication mode of the first base station to the scheduling object received by the terminal
Here, specifically, the first base station may indicate the scheduling object through general signaling or dedicated signaling
5) Indication mode of the second base station to the scheduling object received by the terminal
Here, specifically, the second base station may indicate the scheduling object through general signaling or dedicated signaling
6) Indication mode of scheduling object by third party entity received by terminal
Here, the third party entity may include, but is not limited to: traffic management center, high in the clouds server.
7) Scheduling signaling mode based on DCI through terminal
Here, the DCI scheduling signaling may have an indication field including several bits for indicating a scheduling object. For example, taking "00" indicates that the scheduling object is LTE sidelink.
The scheduling object may also be determined based on attribute information in the DCI scheduling signaling. For example, the DCI scheduling signaling may have a bit length, a useful bit length, a value of a certain field (a certain special code point code), and the like.
8) Scheduling signaling mode based on other DCI except the DCI by the terminal
Here, other DCI scheduling signaling may have an indication field containing several bits for indicating a scheduling object. For example, taking "00" indicates that the scheduling object is LTE sidelink.
The scheduling object may also be determined based on attribute information in other DCI scheduling signaling. For example, the length of the downlink control information bit, the length of the useful bit, the value of a certain field (a certain special code point), and the like.
9) Method for decoding DCI scheduling signaling by terminal in preset format
For example, if the scheduling information is decoded according to DCI format 5A, and the scrambling code is decoded according to another format, it indicates that the scheduling target is LTE sidelink.
In another example, the steps of the resource scheduling method of the present invention include:
step S21, the first base station supporting NR technology acquires an LTE sidelink transmission resource pool;
specifically, the first base station acquires the LTE sidelink transmission resource pool through at least one of network pre-configuration, notification by a second base station supporting the LTE technology, and notification by a third-party entity.
It should be noted that, when the system is in single-network coverage of the NR cellular network and the terminal supports LTE sidelink, the manner in which the terminal acquires the LTE sidelink transmission resource pool is not acquired by the notification manner of the second base station supporting LTE technology.
Step S22, the terminal accesses the first base station to obtain the LTE sidelink transmission resource pool, and automatically becomes the LTE sidelink Mode 4 terminal;
specifically, a system message is sent to the terminal through the first base station supporting the NR technology, and the terminal acquires the LTE sidelink transmission resource pool according to the system message.
Or, step S23, configuring, by the first base station, the terminal as an LTE sidelink Mode 4 terminal;
or, step S24, configuring, by the first base station, the terminal as an LTE sidelink Mode 3 terminal;
in case that the terminal is an LTE sidelink Mode 3 terminal, the method may further include the following steps:
step 25, the terminal reports the resource scheduling request of the terminal to the first base station;
here, the resource scheduling request includes service attribute information, or includes: service attribute information and terminal location information.
In addition, the terminal may report the resource scheduling request and the auxiliary information of the terminal to the first base station; the resource scheduling request comprises service attribute information, and the auxiliary information comprises terminal position information.
Step S26, the first base station negotiates with the second base station about the resource allocation of LTE sidelink.
It should be noted that, when the system is under dual-network coverage of the NR cellular network and the LTE cellular network and the terminal supports LTE sidelink, the second base station supporting the LTE technology participates in resource scheduling for the Mode 3 terminal supporting LTE sidelink, so that the first base station supporting the NR technology needs to negotiate resource allocation of LTE sidelink with the second base station supporting LTE technology to achieve the purpose of reasonably allocating resources of LTE sidelink.
However, when the system is under the coverage of a single network of an NR cellular network and the terminal supports LTE sidelink, the first base station supporting NR technology does not need to negotiate the resource allocation of LTE sidelink with the second base station supporting LTE technology.
Step S27, the first base station sends DCI scheduling signaling to the terminal;
wherein, the DCI scheduling signaling includes all information in the DCI format 5A.
Step S28, the terminal schedules LTE sidelink transmission according to the DCI scheduling signaling.
Specifically, the terminal schedules the LTE sidelink transmission according to the content of the indication of the DCI scheduling signaling.
It should be noted that, when the terminal is a dual-mode terminal, that is, a dual-mode terminal supporting LTE sidelink and NR sidelink, it is necessary to increase the differentiation of DCI scheduling objects, so that the terminal can identify whether the DCI scheduling signaling is used for scheduling LTE sidelink transmission. For a specific distinguishing manner, refer to the contents of the above example section, which is not described herein again.
