Detailed Description
The invention is described in further detail below with reference to the figures and specific examples.
The first embodiment,
An embodiment of the present invention provides a resource scheduling method, which is applied to a first base station in a first communication system, and as shown in fig. 1, the method includes:
step 101: receiving resource request information sent by terminal equipment; wherein the resource request information is used for requesting to schedule a V2X resource of the second communication system;
step 102: and scheduling the V2X resource for the second communication system for the terminal equipment.
Here, the first communication system is a long term evolution, LTE, system, and the second communication system is a new wireless NR communication system; or, the first communication system is an NR communication system, and the second communication system is an LTE system.
The terminal equipment is loaded with equipment of a V2X module of a first communication system and a V2X module of a second communication system, and the terminal equipment accesses the first communication system; specifically, the terminal device is loaded with both LTE V2X and NRV2X modules. The V2X is vehicle to event, i.e. information exchange between the vehicle and the outside.
The scheme provided by the embodiment is applied to the time when the terminal equipment needs to communicate with the terminal equipment only having the LTE V2X module when the terminal equipment is in the NR system; alternatively, when the terminal device is in the LTE system and needs to communicate with a terminal device having only the NR V2X module, it is necessary to acquire V2X communication resources of the opposite end, i.e., the second communication system, from the network side.
The receiving of the resource request information sent by the terminal device includes: and receiving a buffer status report BSR (buffer status report) sent by the terminal equipment and aiming at the V2X resource of the second communication system.
Wherein the buffer status report BSR for the V2X resource of the second communication system includes:
a V2X resource application domain for a second communication system in a MAC Control Element (CE) format of a side link (BSR) of a first communication system; for example, when the first communication system is NR and the second communication system is LTE, as shown in fig. 2, an LTE PC5 resource application field (taking even total LCGs as an example) is added to an NR SidelinkBSR MAC Control Elements format, as can be seen from the figure, a related information field for an LTE logical channel group may be added to a MAC CE format, and a PC5 resource application is performed based on the information;
alternatively, the first and second electrodes may be,
at least one side link BSR MACCE for V2X resource application of the second communication system of the first communication system; for example, when the first communication system is NR and the second communication system is LTE, as shown in the following table, one or more MAC CEs dedicated for LTE V2X resource application are newly added in NR MAC CE, relevant information of the MAC CE used for acquiring LTE side link BSR is added in the list, and the number "xxxxx" thereof may be set according to an actual situation, which is not described in detail in this embodiment:
number Index Logical Channel Identification (LCID) values
00000 CCCH
…… ……
xxxxx Reduced LTE side-link (Sidelink) BSR
xxxxx LTE Sidelink BSR
…… ……
Alternatively, the first and second electrodes may be,
an indication bit in a MAC CE format of a side link BSR of a first communication system, wherein the indication bit is used for indicating that V2X resources aiming at the first communication system or a second communication system are requested; the indication bit may be set according to an actual situation, and may set 1bit as the indication bit, and may set that when the indication bit is equal to 1, the V2X resource for the second communication system is characterized, and when the indication bit is equal to 0, the V2X resource for the first communication system is identified, and vice versa, which is not exhaustive in this embodiment. For example, when the first communication system is NR and the second communication system is LTE, adding 1bit to the NR Sidelink BSR MAC control elements format indicates whether the current format belongs to an LTE PC5 resource application or an NR PC5 resource application.
It should be further noted that, before scheduling V2X resources for the second communication system for the terminal device, the method further includes: the V2X resource allocation information of the second communication system is acquired.
The method for acquiring the V2X resource allocation information of the second communication system may be acquired from the second base station of the second communication system. For example, in LTE, regardless of mode 3 or mode 4, the V2X needs the base station to send the configuration for V2X sidelink communication to the UE, so in a scenario where LTE V2X and NR V2X coexist, any one base station needs to know the relevant configuration of other V2X in order to support scheduling of other RATVs 2X, for example, the NR base station needs to schedule LTE V2X, and needs to know the relevant configuration of LTE V2X.
Wherein, mode 3: the transmission resource of the vehicle-mounted terminal is allocated by the base station, and the vehicle-mounted terminal transmits data on the side uplink according to the resource allocated by the base station; the base station may allocate resources for single transmission to the terminal, or may allocate resources for semi-static transmission to the terminal. Mode 4: the vehicle-mounted terminal adopts a transmission mode of interception (sending) + reservation (reservation). The vehicle-mounted terminal acquires an available transmission resource set in a resource pool in an intercepting mode, and the terminal randomly selects one resource from the set to transmit data.
The specific way to acquire the V2X resource allocation information of the second communication system is as follows:
receiving V2X resource configuration information of the second communication system through the operation, administration and maintenance OAM information;
or, interacting the V2X resource configuration information of the respective communication system with the second base station of the second communication system through an Xn interface;
or, when the first base station and the second base station are the same base station, directly acquiring the V2X resource allocation information of the second communication system.
That is, the second base station of the second communication system can directly send the OAM information to the adjacent first base station; or when the first base station and the second base station are not the same base station, interacting through an Xn interface to obtain related V2X resource configuration information; and when the first base station and the second base station are physically the same base station, the V2X resource configuration information can be directly obtained from the inside.
Wherein the V2X resource configuration information includes at least one of:
V2X receives the resource pool;
V2X sending resource pool;
a V2X scheduled resource pool;
V2X synchronous configuration;
a list of inter-V2X frequency information;
V2X resource selection configuration;
V2X logical channel group information list.
The scheme provided in this embodiment is described with reference to fig. 3, taking the first communication system as NR and the second communication system as LTE as an example, that is, the terminal device 1 is a device equipped with an LTE V2X module and an NR V2X module, and the terminal device 2 is a device equipped with only an LTE V2X module; if the terminal device 1 needs to perform the Sidelink communication of the mode 3 with the terminal device 2 having only the LTE V2X module, the terminal device 1 accessing the NR base station needs to initiate a BSR (Buffer status report) request for the LTE V2X to the NR base station according to the configuration of the NR base station regarding the locatalcchotaplnfolist; and the NR base station schedules the resources for the LTE sidelink for the terminal equipment 1 according to the parameters such as the LTE V2X resource configuration interacted with the adjacent base station and the like.
Therefore, by adopting the scheme, when the terminal equipment requests the V2X resource of other communication systems, the V2X resource of other communication systems can be scheduled, so that the terminal equipment can obtain the transmission resource of other communication systems, and the scheme of scheduling the resource of different communication systems for the terminal equipment under the scene of coexistence of a plurality of communication systems is realized.

and sending a Buffer Status Report (BSR) aiming at the V2X resource of a second communication system to the first base station of the first communication system according to the configuration about the logical channel group information list sent by the first base station of the first communication system.
Wherein the buffer status report BSR for the V2X resource of the second communication system includes:
a V2X resource application domain for a second communication system in a MAC Control Element (CE) format of a side link (BSR) of a first communication system; for example, when the first communication system is NR and the second communication system is LTE, as shown in fig. 2, an LTE PC5 resource application field (taking even total LCGs as an example) is added to an NR SidelinkBSR MAC Control Elements format, as can be seen from the figure, a related information field for an LTE logical channel group may be added to a MAC CE format, and a PC5 resource application is performed based on the information;

Alternatively, the first and second electrodes may be,
an indication bit in a MAC CE format of a side link BSR of a first communication system, wherein the indication bit is used for indicating that V2X resources aiming at the first communication system or a second communication system are requested; the indication bit may be set according to an actual situation, and may set 1bit as the indication bit, and may set that when the indication bit is equal to 1, the V2X resource for the second communication system is characterized, and when the indication bit is equal to 0, the V2X resource for the first communication system is identified, and vice versa, which is not exhaustive in this embodiment. For example, when the first communication system is NR and the second communication system is LTE, adding 1bit to the NR Sidelink BSR MAC control elements format indicates whether the current format belongs to an LTE PC5 resource application or an NR PC5 resource application.
It should be further noted that, before scheduling V2X resources for the second communication system for the terminal device, the method further includes: the V2X resource allocation information of the second communication system is acquired.

Mode 4: the vehicle-mounted terminal adopts a transmission mode of interception (sending) + reservation (reservation). The vehicle-mounted terminal acquires an available transmission resource set in a resource pool in an intercepting mode, and the terminal randomly selects one resource from the set to transmit data.
The scheme provided in this embodiment is described with reference to fig. 3, taking the first communication system as NR and the second communication system as LTE as an example, that is, the terminal device 1 is a device equipped with an LTE V2X module and an NR V2X module, and the terminal device 2 is a device equipped with only an LTE V2X module; if the terminal device 1 needs to perform the Sidelink communication of the mode 3 with the terminal device 2 having only the LTE V2X module, the terminal device 1 accessing the NR base station needs to initiate a BSR (Buffer status report) request for the LTE V2X to the NR base station according to the configuration of the NR base station regarding the locatalcchotaplnfolist; and the NR base station schedules the resources for the LTE sidelink for the terminal equipment 1 according to the parameters such as the LTE V2X resource configuration interacted with the adjacent base station and the like.

For example, if a UE loaded with LTE V2X and NR V2X modules needs to perform Sidelink communication with a UE only having LTE V2X modules, it needs to receive a related configuration message of LTE V2X broadcast by an NR base station or transmitted through an RRC reconfiguration message.
The broadcasting or sending the V2X resource of the second communication system through the RRC reconfiguration message comprises one of the following:

at least one side link BSR MACCE for V2X resource application of the second communication system of the first communication system; for example, when the first communication system is NR and the second communication system is LTE, as shown in the following table, one or more MAC CEs dedicated for LTE V2X resource application are newly added in NR MAC CE, relevant information of the MAC CE used for acquiring LTE side link BSR is added in the list, and the number "xxxxx" thereof may be set according to an actual situation, which is not described in detail in this embodiment:

…… ……
xxxxx Reduced LTE side-link (Sidelink) BSR
xxxxx LTE Sidelink BSR
…… ……
Alternatively, the first and second electrodes may be,
an indication bit in a MAC CE format of a side link BSR of a first communication system, wherein the indication bit is used for indicating that V2X resources aiming at the first communication system or a second communication system are requested; the indication bit may be set according to an actual situation, and may set 1bit as the indication bit, and may set that when the indication bit is equal to 1, the V2X resource for the second communication system is characterized, and when the indication bit is equal to 0, the V2X resource for the first communication system is identified, and vice versa, which is not exhaustive in this embodiment. For example, when the first communication system is NR and the second communication system is LTE, adding 1bit to the NR Sidelink BSR MAC control elements format indicates whether the current format belongs to an LTE PC5 resource application or an NR PC5 resource application.
It should be noted that, before scheduling the V2X resource for the second communication system for the terminal device, the first processor 52 obtains the V2X resource configuration information of the second communication system.
The way of acquiring the V2X resource allocation information of the second communication system can be acquired by the first processor 52 from the second base station of the second communication system through the first communication interface 51. For example, in LTE, regardless of mode 3 or mode 4, the V2X needs the base station to send the configuration for V2X sidelink communication to the UE, so in a scenario where LTE V2X and NR V2X coexist, any one base station needs to know the relevant configuration of other V2X in order to support scheduling of other RAT V2X, for example, the NR base station needs to schedule LTE V2X, and needs to know the relevant configuration of LTE V2X.
Wherein, mode 3: the transmission resource of the vehicle-mounted terminal is allocated by the base station, and the vehicle-mounted terminal transmits data on the side uplink according to the resource allocated by the base station; the base station may allocate resources for single transmission to the terminal, or may allocate resources for semi-static transmission to the terminal. Mode 4: the vehicle-mounted terminal adopts a transmission mode of interception (sending) + reservation (reservation). The vehicle-mounted terminal acquires an available transmission resource set in a resource pool in an intercepting mode, and the terminal randomly selects one resource from the set to transmit data.
The specific way to acquire the V2X resource allocation information of the second communication system is as follows:
the first processor 52 receives the V2X resource configuration information of the second communication system through the operation, administration and maintenance OAM information;
or, the first processor 52 interacts with the second base station of the second communication system through the Xn interface with the V2X resource configuration information of the respective communication system;
or, when the first base station and the second base station are the same base station, the first processor 52 directly obtains the V2X resource allocation information of the second communication system.
That is, the second base station of the second communication system can directly send the OAM information to the adjacent first base station; or when the first base station and the second base station are not the same base station, interacting through an Xn interface to obtain related V2X resource configuration information; and when the first base station and the second base station are physically the same base station, the V2X resource configuration information can be directly obtained from the inside.
Wherein the V2X resource configuration information includes at least one of:
V2X receives the resource pool;
V2X sending resource pool;
a V2X scheduled resource pool;
V2X synchronous configuration;
a list of inter-V2X frequency information;
V2X resource selection configuration;
V2X logical channel group information list.
The scheme provided in this embodiment is described with reference to fig. 3, taking the first communication system as NR and the second communication system as LTE as an example, that is, the terminal device 1 is a device equipped with an LTE V2X module and an NR V2X module, and the terminal device 2 is a device equipped with only an LTE V2X module; if the terminal device 1 needs to perform the Sidelink communication of the mode 3 with the terminal device 2 having only the LTE V2X module, the terminal device 1 accessing the NR base station needs to initiate a BSR (Buffer status report) request for the LTE V2X to the NR base station according to the configuration of the NR base station regarding the locatalcchotaplnfolist; and the NR base station schedules the resources for the LTE sidelink for the terminal equipment 1 according to the parameters such as the LTE V2X resource configuration interacted with the adjacent base station and the like.
Therefore, by adopting the scheme, when the terminal equipment requests the V2X resource of other communication systems, the V2X resource of other communication systems can be scheduled, so that the terminal equipment can obtain the transmission resource of other communication systems, and the scheme of scheduling the resource of different communication systems for the terminal equipment under the scene of coexistence of a plurality of communication systems is realized.

For example, when the first communication system is NR and the second communication system is LTE, adding 1bit to the NR Sidelink BSR MAC control elements format indicates whether the current format belongs to an LTE PC5 resource application or an NR PC5 resource application.
It should be further noted that, before scheduling V2X resources for the second communication system for the terminal device, the method further includes: the V2X resource allocation information of the second communication system is acquired.
The method for acquiring the V2X resource allocation information of the second communication system may be acquired from the second base station of the second communication system. For example, in LTE, regardless of mode 3 or mode 4, the V2X needs the base station to send the configuration for V2X sidelink communication to the UE, so in a scenario where LTE V2X and NR V2X coexist, any one base station needs to know the relevant configuration of other V2X in order to support scheduling of other RATVs 2X, for example, the NR base station needs to schedule LTE V2X, and needs to know the relevant configuration of LTE V2X.
