Description

Resource allocation method and device

Technical Field

The present application relates to the field of communications technologies, and in particular, to a resource allocation method and apparatus.

Background

When a vehicle connects to all (V2X) terminal devices and resides in a cell, the V2X terminal devices will use a resource pool (resource pool) configured by the current cell for data transmission, the resource pool of the cell may include a receiving resource pool (RX pool), a transmitting resource pool (TX pool), and a special transmitting resource pool (exceptinotaltxol), the receiving resource pool is used to inform the V2X terminal devices on which resources the terminal devices need to receive signals on a sidelink (S L), the V2X terminal devices may select resources from the transmitting resource pool for transmission when the current cell transmits on S L, and the special transmitting resource pool is used for selecting resources in a special case, such as cell handover, cell reselection, or link failure, the V2X terminal devices may select resources in the special transmitting resource pool for transmission at random.

When the V2X terminal device selects a resource from the sending resource pool to perform S L transmission, it will first detect (sending) the sending resource pool and obtain a sending result of the sending resource pool, sending refers to selecting a sending resource that is not currently occupied in the sending resource pool to perform transmission by listening to the occupation of different time-frequency resources in the sending resource pool within a period of time, so as to reduce the probability of collision caused by the different terminal devices selecting one resource at the same time.

And when the V2X terminal device performs cell reselection or cell handover, it will obtain the resource pool of the new cell, and use the resource pool of the new cell for data transmission after accessing the target cell. After the V2X terminal device obtains the resource pool of the new cell, it is the resource pool that has changed for the V2X terminal device, so the V2X terminal device needs to send the resource pool of the new cell. However, in many cases, after the V2X terminal device enters the new cell, the same transmission resource pool as the old cell is used, but the V2X terminal device still considers the new transmission resource pool, and still performs sending again, which increases the invalid operation process of the V2X terminal device, causes performance degradation due to the use of the special transmission resource pool, and also increases the power consumption of the V2X terminal device.

Here, the fifth communication apparatus is exemplified as a network device.

In the embodiment of the present application, the cell to which the V2X resource is applicable is indicated by the identifier of the area, which is simpler than the way of setting the indication information and is more advantageous for saving transmission overhead.

With reference to the fifth aspect, in a first possible implementation manner of the fifth aspect, a system information block SIB for configuring the V2X resource is different from a region-specific SIB.

The area ID in the NR technology may be multiplexed to identify the area in the embodiment of the present application, and the area ID in the NR technology is not for the V2X resource, but the embodiment of the present application may multiplex in this way, so that the area ID corresponds to the V2X resource, or corresponds to the SIB for configuring the V2X resource. Then, the area ID in the embodiment of the present application corresponds to the same area as the area ID existing in the NR technique, for example, the area IDs 1 all correspond to the area 1, the area IDs 2 all correspond to the area 2, and so on. Or, the area corresponding to the area ID in the current NR technology has a large range, and if the same resource pool is used in a large area, the resource utilization rate of some cells in the area may be low.

With reference to the fourth possible implementation manner of the fifth aspect, in a fifth possible implementation manner of the fifth aspect, the V2X load of the first cell does not satisfy a load threshold, where the V2X load is used to indicate the number of terminal devices using the V2X resource or the amount of data transmitted using the V2X resource.

The network device may adjust the identifier of the V2X resource of the first cell to be the second identifier according to the V2X load condition of the first cell, where the adjusting may refer to the network device adjusting the identifier of the V2X resource of the first cell to be the second identifier when the V2X load of the first cell does not satisfy the load threshold. The V2X load of the first cell does not satisfy the load threshold, which may mean that the load of the first cell is greater than (or equal to) the load threshold, or may also mean that the load of the first cell is less than (or equal to) the load threshold.

The method may be performed by a sixth communication device, which may be a terminal equipment or a communication device, such as a system-on-chip, capable of supporting the terminal equipment to implement the functions required by the method. Here, the sixth communication apparatus is exemplified as a terminal device.

With reference to the sixth aspect, in a first possible implementation manner of the sixth aspect, the system information block SIB for configuring the V2X resource is different from a region-specific SIB.

With reference to the sixth aspect or the first possible implementation manner of the sixth aspect, in a second possible implementation manner of the sixth aspect, the V2X resource includes a V2X resource pool for at least one terminal device application, or includes a dedicated V2X resource for one terminal device application.

With reference to the second possible implementation manner of the sixth aspect, in a third possible implementation manner of the sixth aspect, the V2X resource pool includes at least one of: a transmit resource pool for providing V2X transmit resources, a receive resource pool for providing V2X receive resources, and a special transmit resource pool for providing V2X transmit resources.

If the network device adjusts the identifier of the area corresponding to the V2X resource of the first cell, the network device needs to notify the terminal device, so that the terminal device can obtain the V2X resource corresponding to the identifier of the new area again.

using a special sending resource pool corresponding to the second identifier and used for providing sending resources, and detecting the sending resource pool corresponding to the second identifier and used for providing the sending resources; or the like, or, alternatively,

using the special sending resource pool corresponding to the second identifier for providing the sending resource until obtaining a detection sending result of the sending resource pool corresponding to the second identifier for providing the sending resource; or the like, or, alternatively,

and using the V2X resource corresponding to the second identification.

If the identity of the V2X resource of the first cell changes, it indicates that the V2X resource of the first cell has changed, so it is necessary for the terminal device to use the V2X resource corresponding to the second identity. If the V2X resource corresponding to the second identifier is the V2X resource pool, the terminal device needs to perform sending on the sending resource pool in the V2X resource pool first, and use the special sending resource pool in the V2X resource pool until obtaining the sending result of the sending resource pool in the V2X resource pool, and then use the sending resource pool in the V2X resource pool.

With reference to the sixth possible implementation manner of the sixth aspect, in a seventh possible implementation manner of the sixth aspect, the determining whether to use the V2X resource after reselection or handover to the second cell includes:

receiving a fourth message containing an identification of an area for which V2X resources of the second cell are applicable;

determining whether the identity of the area to which the V2X resource of the second cell is applicable is the same as the first identity according to the fourth message;

continuing to use the V2X resource after reselecting or handing over to the second cell if the identity of the region to which the V2X resource applies is the same as the first identity, or using the V2X resource of the second cell after reselecting or handing over to the second cell if the identity of the region to which the V2X resource applies is not the same as the first identity.

If the identifier of the region to which the V2X resource applies is the same as the first identifier, which indicates that the V2X resource to which the second cell applies is the same as the V2X resource corresponding to the first identifier, the terminal device may continue to use the V2X resource without obtaining the V2X resource of the second cell, which reduces the steps of obtaining the V2X resource by the terminal device. And the terminal equipment can directly use the sending resource pool of the V2X resource when using the V2X resource, and does not need to perform sending any more, thereby reducing the operation process of the terminal equipment, and improving the transmission performance because the special sending resource pool of the V2X resource is not needed.

With reference to the sixth aspect or any one of the first possible implementation manner of the sixth aspect to the seventh possible implementation manner of the sixth aspect, in an eighth possible implementation manner of the sixth aspect, the first message further includes V2X resources of the first cell; or, the method further comprises: receiving a second message from the network device, the second message including V2X resources of the first cell.

With regard to the technical effects brought by the sixth aspect or the various embodiments of the sixth aspect, reference may be made to the introduction of the technical effects of the fifth aspect or the various embodiments of the fifth aspect, and details are not repeated.

For example, the first identifier and the second identifier are used only for distinguishing different identifiers, and do not indicate the difference of the content, priority, importance, and the like of the two identifiers.

Having described some of the concepts related to the embodiments of the present application, the following describes features of the embodiments of the present application.

V2X is a key technology of the future intelligent transportation system. It enables communication between cars, between cars and base stations, and between base stations. Therefore, a series of traffic information such as real-time road conditions, road information, pedestrian information and the like is obtained, so that the driving safety is improved, the congestion is reduced, the traffic efficiency is improved, and the vehicle-mounted entertainment information is provided.

In the L TE system, the V2X terminal device in the coverage area obtains the transmission configuration at S L according to the configuration message sent by the base station through the Uu interface, so as to broadcast to other terminal devices at S L according to the transmission configuration, which can refer to fig. 2, wherein, the terminal devices capable of performing the V2X service may be referred to as V2X terminal devices.

There are two ways in which the base station controls vehicle-to-vehicle communication, mode (mode)3 and mode 4. The mode3 refers to that the base station sends dedicated signaling to the V2X terminal device in the connected state, and the dedicated signaling carries a sending resource for the V2X terminal device to send data. The transmission resource carried by the dedicated signaling may be a dedicated transmission resource or a resource pool. mode4 indicates that in the connected or idle state, the base station provides the connected or idle terminal device with a resource pool through dedicated signaling or broadcast information (e.g. System Information Blocks (SIB) 21 or SIB26), and the V2X terminal device selects resources from the transmission resource pool to transmit to other terminal devices.

The connected V2X terminal device may receive the resource pool configured by the base station through dedicated signaling, for example, the resource pool includes a receiving resource pool, a transmitting resource pool, and a special transmitting resource pool, and the idle V2X terminal device may acquire the receiving resource pool, the transmitting resource pool, and the special transmitting resource pool by reading the system broadcast SIB21 and SIB 26.

The V2X terminal device may select resources from the sending resource pool for transmission when the current cell transmits on S L, and the special sending resource pool is used for, under special conditions, such as cell handover, cell reselection, or link failure, the V2X terminal device may randomly select resources from the special sending resource pool for sending.

In the NR system, similarly, the V2X service corresponds to mode1 and mode2, the mode1 is controlled in a manner similar to mode3 in L TE system, the mode2 is controlled in a manner similar to mode4 in L TE system, and the V2X service of the NR system can be further unicast to one terminal device or multicast to a group of terminal devices through S L. for mode1 and mode3, the base station may allocate a dedicated resource or resource pool to the V2X terminal device for transmission by the V2X terminal device, for mode2 and mode4, the base station allocates a resource pool to the V2X terminal device for transmission by the V2X terminal device, wherein the dedicated resource means dedicated resource is dedicated to the V2X terminal device for transmission, the V2X terminal device does not need to compete with other terminal devices or select resources again, and the resource pool may be used by multiple V2X terminal devices, and the V2 terminal device also needs to select resources from 2X pool.

When the V2X terminal device selects resources from the sending resource pool to perform S L transmission, sending is performed on the sending resource pool first, and a sending result of the sending resource pool is obtained, sending means that currently unoccupied sending resources in the sending resource pool are selected to be transmitted by listening to the occupation situation of different time-frequency resources in the sending resource pool within a period of time, so that the probability of collision caused by the fact that different V2X terminal devices select one resource at the same time is reduced.

When a V2X terminal device resides in a different cell, the V2X terminal device will transmit and receive using the resource pool configured by the current cell. When a V2X terminal device in an idle state performs cell reselection, it currently acquires transmission resources of a new cell by acquiring SIB21 and SIB26 of the new cell, where the transmission resources of the new cell may be dedicated resources or a resource pool. If the transmission resource of the new cell is a resource pool, the V2X terminal device needs to perform sending on the transmission resource pool after obtaining the resource pool of the new cell, and before obtaining the sending result, the terminal device uses the special transmission resource pool provided in the SIB to transmit data in the new cell. The transmission interruption of the V2X terminal device due to reading SIB21 and SIB26 is implemented by the V2X terminal device. Please refer to fig. 3, which is a schematic diagram of the terminal device V2X using different transmission resources at different times. For example, the transmission resource pool used before cell reselection is resource pool 1, that is, the transmission resource pool of the old cell, after cell reselection, when SIB21 or SIB26 of the new cell is not acquired, transmission may be interrupted, after the resource pools of SIB21 and SIB26 of the new cell are acquired, the V2X terminal device will transmit data using the special transmission resource pool of the new cell, and at the same time perform sensing on the transmission resource pool of the new cell (resource pool 2 in fig. 3), and after the sensing result on resource pool 2 is acquired, perform transmission using resource pool 2.

For the connected V2X terminal equipment, the base station issues a handover command (HO command), mobile control information (mobility control information) is contained in the handover command, the mobility control information-V2 x (mobility control information-V2 x) is contained in the mobility control information, and the mobility control information-V2 x can be used for configuring a special transmission resource pool and a special receiving resource pool.

The V2X terminal device uses the special transmission resource pool configured in the HO command to reduce the transmission interruption before completing the connection with the new cell and before acquiring the sending result of the new cell. Referring to fig. 4, it is a schematic diagram of the terminal device V2X using different transmission resources at different times. For example, before receiving the handover command, the transmission resource pool of the old cell is used, which is indicated as resource pool 1 in fig. 4; there will be an interruption after receiving the handover command and before it is not synchronized with the new cell; after synchronizing with the new cell, sending data by using the special sending resource pool configured in the handover command, and sending the sending resource pool (indicated as resource pool 2 in fig. 4) of the new cell, where the sending resource pool of the new cell may be configured together by the handover command, or may be reconfigured by the new cell after accessing the new cell, and fig. 4 takes new cell reconfiguration as an example, then sending the sending resource pool of the new cell is started when the sending resource pool of the new cell is reconfigured by the new cell; and after the sending result of the resource pool 2 is obtained, the resource pool 2 is used for transmission.

No matter the V2X terminal equipment in a connection state or the V2X terminal equipment in an idle state, the special sending resource pool can ensure the terminal equipment to send, and sending interruption is reduced. However, since the sending process is not required in the special transmission resource pool, multiple V2X terminals can randomly select resources from the special transmission resource pool, which may cause a certain degree of collision, and may result in poor performance of the terminal when performing cell handover or cell reselection.

And, as long as the sending resource pool changes, the terminal equipment will perform sending again. In many cases, after the terminal device enters the new cell, the same transmission resource pool as the old cell is actually used, but the terminal device still considers that the terminal device is the new transmission resource pool, and still performs sending again, which increases the invalid operation process of the terminal device and also increases the power consumption of the terminal device.

In view of this, the technical solutions of the embodiments of the present application are provided. In the embodiment of the present application, the cell or the frequency to which the V2X resource is applicable may be indicated by the first message, so that when the terminal device performs cell reselection or cell handover, it may be clear which cells or frequencies continue to apply the V2X resource, and if the terminal device reselects or switches to these cells, the terminal device may not perform sending on the V2X resource, but may directly use the cell or the frequency, which reduces an operation process of the terminal device, saves power consumption of the terminal device, and also improves transmission efficiency.

The technical solution provided in the embodiment of the present application may be applied to a V2X scenario, an NR V2X scenario, a L TE V2X scenario, or the like, or may also be applied to other scenarios or other communication systems, which is not limited specifically.

The network architecture applied in the embodiments of the present application is described below. Please refer to fig. 5, which illustrates a network architecture applied in the present embodiment.

Fig. 5 includes a network device and two terminal devices, which are respectively a terminal device 1 and a terminal device 2, where both of the two terminal devices may be under the coverage of the network device, or the two terminal devices may only have the terminal device 1 under the coverage of the network device and the terminal device 2 not under the coverage of the network device, and the two terminal devices may also communicate with each other through sidelink, or the two terminal devices may also be under the coverage of different network devices. Fig. 5 takes as an example that both terminal devices are under the coverage of one network device shown in fig. 5. Wherein both terminal devices are V2X terminal devices. Of course, the number of terminal devices in fig. 5 is only an example, and in practical applications, the network device may provide services for a plurality of terminal devices.

The network device in fig. 5 is, for example, an access network device, such as a base station, or may also be an RSU, etc., and the base station is taken as an example in fig. 5. Wherein the access network equipment corresponds to different equipment on different systems, such as in the fourth generation mobile communication technology (the 4)^thgeneration, 4G) system may correspond to an eNB, and in a 5G system corresponds to an access network device in 5G, for example, a gNB.

The terminal device in fig. 5 is a vehicle-mounted terminal device or a vehicle as an example, but the terminal device in the embodiment of the present application is not limited thereto.

The technical solution provided by the embodiments of the present application is described below with reference to the accompanying drawings.

The embodiment of the present application provides a first resource allocation method, please refer to fig. 6A, which is a flowchart of the method. In the following description, the method is applied to the network architecture shown in fig. 5 as an example. In addition, the method may be performed by two communication devices, e.g. a first communication device and a second communication device. The first communication device may be a network device or a communication device capable of supporting the network device to implement the functions required by the method, or may be a terminal device or a communication device capable of supporting the terminal device to implement the functions required by the method, or may be other communication devices, such as a system on a chip. Similarly, the second communication device may be a network device or a communication device capable of supporting the network device to implement the functions required by the method, or may be a terminal device or a communication device capable of supporting the terminal device to implement the functions required by the method, or may be other communication devices, such as a system on chip. The implementation manners of the first communication device and the second communication device are not limited, for example, the two communication devices may be implemented in the same form, for example, both are implemented in the form of a device, or the two communication devices may also be implemented in different forms, for example, the first communication device is implemented in the form of a device, the second communication device is implemented in the form of a system-on-chip, and so on. The network device is, for example, a base station.

For convenience of introduction, in the following, the method is performed by a network device and a terminal device as an example, that is, the first communication apparatus is a network device and the second communication apparatus is a terminal device as an example. Since this embodiment is applied to the network architecture shown in fig. 5 as an example, the network device described below may be the network device in the network architecture shown in fig. 5, and the terminal device described below may be the terminal device 1 or the terminal device 2 in the network architecture shown in fig. 5, and if the terminal device described below is the terminal device 1 in the network architecture shown in fig. 5, the other terminal device described below may be the terminal device 2 in the network architecture shown in fig. 5, or if the terminal device described below is the terminal device 2 in the network architecture shown in fig. 5, the other terminal device described below may be the terminal device 1 in the network architecture shown in fig. 5. In addition, for the sake of simplicity of description, the V2X terminal device is also referred to simply as a terminal device hereinafter.

S61, the network equipment generates a first message, wherein the first message comprises indication information, the indication information is used for indicating first information applicable to V2X resources of a first cell, and the first information is cell information and/or frequency information.

The first message may be a system message or may be dedicated signaling. As an embodiment, the first message may further include the V2X resource of the first cell. For example, for a connected terminal device or an idle terminal device, the network device may indicate the V2X resource of the first cell through a system message. The system messages include, for example, SIB21 and SIB 26. Alternatively, for the terminal device in the connected state, the network device may further indicate the V2X resource of the first cell through dedicated signaling, for example, an RRC reconfiguration message. The first cell may be a cell under the network device, the first cell is a cell where the network device sends the dedicated signaling if the first message is the dedicated signaling, the first cell is one of a plurality of cells if the first message is a broadcast message (e.g., a system message) the network device may broadcast the system message in the plurality of cells, or the first cell is a cell if the network device may broadcast the system message in only one cell. The saving of signaling overhead is facilitated by a message that includes both the V2X resource and the indication information.

Alternatively, as another embodiment, the first message may not include the V2X resource of the first cell, and instead, the network device may also send the second message at the first cell, with the second cell including the V2X resource. Therefore, the V2X resource and the indication information can be sent in different messages, and the transmission reliability is improved. Similarly, the second message may be a system message or may be dedicated signaling, and the type of the first message and the type of the second message may be the same, for example, the first message is a system message, but not the same system message, or the type of the first message and the type of the second message may be different, for example, the first message is a system message and the second message is dedicated signaling, or the first message is dedicated signaling and the second message is a system message, which is not limited specifically. After the network device generates the second message, if the second message is dedicated signaling, the network device sends the second message in the first cell, where "send" may be understood as unicast, or if the second message is a system message, the network device broadcasts the second message in the first cell, and the terminal device may receive the second message from the network device in the first cell. The network device may send the first message and then send the second message, or may send the second message and then send the first message, or may send the first message and the second message at the same time.

The V2X resource may include a V2X resource pool for at least one terminal device, or a dedicated V2X resource for a terminal device, which is the terminal device receiving the first message. Wherein the V2X resource pool comprises at least one of the following: a transmit resource pool for providing V2X transmit resources, a receive resource pool for providing V2X receive resources, and a special transmit resource pool for providing V2X transmit resources. The dedicated V2X resource is a V2X resource dedicated for use by one terminal device that does not have to compete with other terminal devices, the dedicated V2X resource may include a transmission resource and/or a reception resource, and for the transmission resource included in the dedicated V2X resource, the terminal device does not have to perform sensing but may directly use it.

For example, if the first message or the second message including the V2X resource is dedicated signaling, the V2X resource may be a V2X resource pool, may be a dedicated V2X resource, or if the first message or the second message including the V2X resource is a system message, the V2X resource may be a V2X resource pool.

Indication information is included in the first message for indicating first information that the V2X resource is applicable. Herein, the first information to which the V2X resource is applicable means that, if the terminal device switches or reselects to the cell (or frequency) corresponding to the first information, the cell after the switching or reselection can still use the V2X resource. In the embodiment of the present application, the indication information is used to indicate the first information used by the V2X resource, and includes but is not limited to one of the following ways:

1. the indication information includes information of a cell to which the V2X resource is applicable, and/or includes information of a frequency to which the V2X resource is applicable. Specifically, the indication information includes information of a cell to which the V2X resource is applicable or information of a frequency to which the V2X resource is applicable, or includes information of a cell to which the V2X resource is applicable and information of a frequency to which the V2X resource is applicable; or the like, or, alternatively,

2. the indication information is used to indicate whether the V2X resource is applicable to a neighboring cell of the first cell, and/or is used to indicate whether the V2X resource is applicable to a neighboring frequency of a frequency of the first cell (or referred to as a neighboring frequency, where the neighboring frequency refers to a frequency of a neighboring cell that can be searched by a cell where the terminal device currently resides, where the cell where the terminal device currently resides is the first cell). Specifically, the indication information is used to indicate whether the V2X resource is applicable to the neighboring cell of the first cell, or is used to indicate whether the V2X resource is applicable to the neighboring frequency of the first cell, or is used to indicate whether the V2X resource is applicable to the neighboring cell of the first cell, and whether the V2X resource is applicable to the neighboring frequency of the first cell; or the like, or, alternatively,

3. the indication information includes an identification of an area to which the V2X resource applies, the identification of the area being used to determine first information to which the V2X resource applies.

The information of the cell is, for example, an identifier of the cell, such as an ID of the cell, or may be other information for uniquely indicating a cell.

Regarding type 1, it can be understood that indication information is added to the V2X resource, and the indication information may indicate first information to which the V2X resource is applicable. For example, the indication information may be implemented by a list (list) including first information applicable to the V2X resource, for example, including an ID of a cell to which the V2X resource is applicable, and/or including frequency information applicable to the V2X resource. Of course, the indication information may be implemented in other ways besides the list, and is not limited in particular.

With respect to type 2, that is, indicating whether V2X resources are applicable to the neighbor cell and/or the neighbor frequency of the first cell. In addition, the network device may also send a system message, where the system message may carry neighboring cell information and/or neighboring frequency information of the first cell. If the first message is a system message, that is, the first message may indicate whether the V2X resource is applicable to the neighboring cell and/or the neighboring frequency of the first cell, or may indicate the neighboring cell information and/or the neighboring frequency information of the first cell. Then, for the terminal device, after receiving the first message, it may know the neighboring cell information and/or the neighboring frequency information of the first cell, and may also know whether the V2X resource is applicable to the neighboring cell and/or the neighboring frequency of the first cell, so as to know the first information applicable to the V2X resource, and the terminal device may know a variety of information only through one message, which is relatively simple. Alternatively, if the first message is dedicated signaling, that is, the first message may indicate whether the V2X resource is applicable to the neighbor cell and/or the neighbor frequency of the first cell, and the network device further indicates the neighbor cell information and/or the neighbor frequency information of the first cell through a system message. Then, for the terminal device, after receiving the first message, it may know the neighboring cell information and/or the neighboring frequency information of the first cell, and after receiving the system message, it may know whether the V2X resource is applicable to the neighboring cell and/or the neighboring frequency of the first cell, so that it may also know the first information applicable to the V2X resource.

In this case, regardless of whether the first information of the first cell indicated by the system message is one or more, the V2X resource is either all the first information simultaneously applicable to the first cell or all the first information simultaneously not applicable to the first cell. For example, if there are a plurality of neighboring cells of the first cell indicated by the system message, the first message indicates that the V2X resource is applicable to the neighboring cells of the first cell, which can be understood as that the V2X resource is applicable to all the neighboring cells of the first cell; for another example, if there are multiple adjacent frequencies of the first cell indicated by the system message, the first message indicates that the V2X resource is applicable to the adjacent frequencies of the first cell, which can be understood as that the V2X resource is applicable to all the adjacent frequencies of the first cell. For example, the indication information may be implemented by 1 bit (bit) or several bits, and then only 1 bit or several bits are needed to indicate whether the plurality of first information applies to the V2X resource, for example, 1 bit indicates whether the plurality of first information applies to the transmission resource pool of V2X, another bit indicates whether the plurality of first information applies to the reception resource pool of V2X, and it is not necessary to separately indicate for each first information, which is helpful to save the number of bits occupied by the indication information.

In the embodiment of the present application, the V2X resource may correspond to an identifier of a corresponding area, where the identifier of an area is used to indicate an area, and the area may include a cell or a plurality of cells (or include cells at one or more frequencies). It is understood that if the V2X resource used does not change within a geographic area, the geographic area belongs to an area corresponding to the identity of the area. Then, if the identities of the two regions are the same, it means that the V2X resources of the two regions are the same, and if the identities of the two regions are different, it means that the V2X resources of the two regions are different. Since the V2X resource corresponds to a cell or a frequency, the identifier of the region may be considered to correspond to the V2X resource, or may be considered to correspond to the cell or the frequency, for example, the identifier of the region may be described as the identifier of the region corresponding to the V2X resource, or may be described as the identifier of the region corresponding to the cell or the frequency. Then, regarding the 3 rd way, the indication information indicates the identity of the area to which the V2X resource is applicable, for example, the indication information is implemented by the identity of the area to which the V2X resource is applicable, and the identity of the area to which the V2X resource is applicable can be used to determine the first information to which the V2X resource is applicable, that is, if the identity of the area to which the cell after handover or reselection is located is the same as the identity of the area to which the V2X resource is applicable when the terminal device performs cell handover or cell reselection, it indicates that the V2X resource used by the cell after handover or reselection is the same as the V2X resource, and if the identity of the area to which the cell after handover or reselection is corresponding is different from the identity of the area to which the V2X resource is applicable, it indicates that the V2X resource used by the cell after handover or reselection is different from the V2X resource. The zone identities for different V2X resources may be different, as the zone identity for the received V2X resource may be different from the zone identity for the transmitted V2X resource.

S62, the network device sends or broadcasts the first message in the first cell, and the terminal device receives the first message from the network device in the first cell.

The first cell may be a serving cell of the terminal device. After the network device generates the first message, if the first message is dedicated signaling, the network device sends the first message in the first cell, where "send" may be understood as unicast, or if the first message is a system message, the network device broadcasts the first message in the first cell, and the terminal device may receive the first message from the network device.

S63, the terminal device determines first information applicable to the V2X resource according to the indication information included in the first message, wherein the first information is cell information and/or frequency information.

The terminal device may also determine the V2X resources from the first message if the first message also includes the V2X resources of the first cell, or the V2X resources from the second message after receiving the second message if the second message includes the V2X resources.

If the indication information includes information of a cell to which the V2X resource is applicable, the terminal device may determine information of a cell to which the V2X resource is applicable from the indication information; or, if the indication information includes information of a frequency to which the V2X resource is applicable, the terminal device may determine information of a frequency to which the V2X resource is applicable according to the indication information; or, if the indication information includes information of a cell to which the V2X resource is applicable and information of a frequency to which the V2X resource is applicable, the terminal device may determine the information of the cell to which the V2X resource is applicable and the information of the frequency to which the V2X resource is applicable from the indication information.

Or, if the indication information is used to indicate whether the V2X resource is applicable to the neighboring cell of the first cell, the terminal device may determine whether the V2X resource is applicable to the neighboring cell of the first cell according to the indication information; or, if the indication information is used to indicate whether the V2X resource is applicable to a neighboring frequency of the first cell, the terminal device may determine whether the V2X resource is applicable to a neighboring frequency of the first cell according to the indication information; or, if the indication information is used to indicate whether the V2X resource is applicable to the neighboring cell of the first cell and whether the V2X resource is applicable to the neighboring frequency of the first cell, the terminal device may determine whether the V2X resource is applicable to the neighboring cell of the first cell and whether the V2X resource is applicable to the neighboring frequency of the first cell according to the indication information. Wherein adjacent frequencies are also referred to hereinafter simply as adjacent frequencies.

Alternatively, if the indication information includes an identifier of an area to which the V2X resource applies, and the identifier of the area is used to determine the first information to which the V2X resource applies, the terminal device may determine the area to which the V2X resource applies according to the indication information, or may determine the cell or frequency to which the V2X resource applies according to the indication information.

As an embodiment, when performing cell reselection or cell handover subsequently, the terminal device may determine whether the second cell is suitable for the V2X resource, where the second cell refers to a cell after cell reselection or cell handover, and for example, the second cell may also be referred to as a target cell.

For example, if the indication information includes information of a cell to which the V2X resource is applicable, the terminal device may determine, from the indication information, information of a cell to which the V2X resource is applicable, if the second cell belongs to a cell to which the V2X resource is applicable, the V2X resource is applicable to the second cell, and if the second cell does not belong to a cell to which the V2X resource is applicable, the V2X resource is not applicable to the second cell.

Alternatively, if the indication information is used to indicate whether the V2X resource is applicable to the neighboring cell of the first cell, the terminal device may determine, according to the indication information, that the V2X resource is applicable to the neighboring cell of the first cell or not applicable to the neighboring cell of the first cell. Then, if the second cell is a neighboring cell of the first cell and the indication information indicates that the V2X resource is applicable to the neighboring cell of the first cell, the terminal device determines that the V2X resource is applicable to the second cell; or, if the second cell is a neighboring cell of the first cell, and the indication information is used to indicate that the V2X resource is not applicable to the neighboring cell of the first cell, the terminal device determines that the second cell is not applicable to the V2X resource; or, if the second cell is not a neighboring cell of the first cell, and the indication information is used to indicate that the V2X resource is applicable to the neighboring cell of the first cell, the terminal device cannot determine whether the second cell is applicable to the V2X resource; or, if the second cell is not a neighboring cell of the first cell, and the indication information is used to indicate that the V2X resource is applicable to the neighboring cell of the first cell, the terminal device cannot determine whether the second cell is applicable to the V2X resource.

As another embodiment, when performing cell reselection or cell handover subsequently, the terminal device may determine whether the frequency of the second cell is suitable for the V2X resource.

For example, if the indication information includes frequency information to which the V2X resource applies, the terminal device may determine, according to the indication information, frequency information to which the V2X resource applies, if the frequency of the second cell belongs to the frequency to which the V2X resource applies, the terminal device determines that the frequency of the second cell applies to the V2X resource, that is, the second cell applies to the V2X resource, and if the frequency of the second cell does not belong to the frequency to which the V2X resource applies, the terminal device determines that the frequency of the second cell does not apply to the V2X resource, that is, the second cell does not apply to the V2X resource.

Alternatively, if the indication information is used to indicate whether the V2X resource is applicable to the neighboring frequency of the first cell, the terminal device may determine that the V2X resource is applicable to the neighboring frequency of the first cell or not applicable to the neighboring frequency of the first cell according to the indication information. Then, if the second cell is under the adjacent frequency of the first cell and the indication information is used to indicate that the V2X resource is applicable to the adjacent frequency of the first cell, the terminal device determines that the adjacent frequency of the second cell is applicable to the V2X resource, and may also consider that the second cell is applicable to the V2X resource; or, if the frequency of the second cell is the adjacent frequency of the first cell, and the indication information is used to indicate that the V2X resource is not applicable to the adjacent frequency of the first cell, the terminal device determines that the frequency of the second cell is not applicable to the V2X resource, that is, the second cell is not applicable to the V2X resource; or, if the frequency of the second cell is not the adjacent frequency of the first cell, and the indication information is used to indicate that the V2X resource is applicable to the adjacent frequency of the first cell, the terminal device cannot determine whether the frequency of the second cell is applicable to the V2X resource, that is, cannot determine whether the second cell is applicable to the V2X resource; or, if the frequency of the second cell is not the adjacent frequency of the first cell, and the indication information is used to indicate that the V2X resource is applicable to the adjacent frequency of the first cell, the terminal device cannot determine whether the frequency of the second cell is applicable to the V2X resource, that is, cannot determine whether the second cell is applicable to the V2X resource.

If the terminal device determines that the second cell or the frequency of the second cell is suitable for the V2X resource, the terminal device may continue to use the V2X resource after reselecting or switching to the second cell, so that the terminal device does not need to acquire the V2X resource of the second cell, and the process of acquiring the resource by the terminal device is reduced. Moreover, if the V2X resource is the V2X resource pool, the terminal device does not need to send the transmission resource pool in the V2X resource pool, so as to reduce the power consumption of the terminal device, and the terminal device does not need to use a special transmission resource pool in the V2X resource pool, but can directly use the transmission resource pool, so as to reduce the possible conflict between the terminal device and other terminal devices in selecting resources.

Referring again to FIG. 6B, the general process of the embodiment of FIG. 6A can be seen through FIG. 6B. As can be seen from fig. 6B, the network device may send or broadcast a first message, where the first message is a dedicated signaling or a system message, the first message is used to configure V2X resources of the first cell, the V2X resources include dedicated V2X resources or a V2X resource pool, the first message includes indication information for indicating first information that the V2X resources are applicable, fig. 6B takes the example that the first information is cell information, and fig. 6B takes the example that the indication information includes an identification of a cell to which the V2X resources are applicable. Then the terminal device need not obtain the V2X resource of the second cell but continues to use the V2X resource of the first cell when handing over or reselecting to the second cell if the second cell is the cell to which the V2X resource applies.

Referring also back to FIG. 6C, the general process of the embodiment of FIG. 6A can also be seen by FIG. 6C. As can be seen from fig. 6C, the network device may send or broadcast a first message, where the first message is a dedicated signaling or a system message, the first message is used to configure V2X resources of the first cell, the V2X resources include dedicated V2X resources or a V2X resource pool, the first message includes indication information for indicating first information to which the V2X resources are applicable, fig. 6C takes the example that the first information is cell information, and fig. 6C takes the example that the indication information is 1 bit for indicating that the V2X resources are applicable to a neighboring cell of the first cell. Then the terminal device need not obtain the V2X resource of the second cell but continues to use the V2X resource of the first cell when switching or reselecting to the second cell if the second cell is a neighbor of the first cell.

Referring additionally to FIG. 6D, the general process of the embodiment of FIG. 6A can also be seen with FIG. 6D. In addition, fig. 6B and fig. 6C both take the example that the first message includes both the V2X resource and the indication information, and in fig. 6D, the V2X resource and the indication information are sent through different messages. As can be seen from fig. 6D, the network device may send or broadcast a first message, where the first message is a dedicated signaling or a system message, the first message includes indication information for indicating first information to which the V2X resource of the first cell applies, fig. 6D takes the first information as cell information as an example, and fig. 6D takes the indication information as 1 bit for indicating that the V2X resource applies to a neighboring cell of the first cell as an example. The network device may also send or broadcast a second message, the second message being a dedicated signaling or a system message, the second message being used to configure the V2X resource of the first cell, the V2X resource comprising a dedicated V2X resource or a V2X resource pool. Then the terminal device need not obtain the V2X resource of the second cell but continues to use the V2X resource of the first cell when switching or reselecting to the second cell if the second cell is a neighbor of the first cell.

Alternatively, if the terminal device determines that the second cell or the frequency of the second cell does not apply to the V2X resource, the terminal device may acquire and use the V2X resource of the second cell after cell reselection or cell handover to the second cell. For example, the terminal device may obtain the V2X resource of the second cell through a system message sent by the second cell, or may obtain the V2X resource of the second cell through a handover command sent by the first cell, or may also obtain the V2X resource configured by the second cell after accessing the second cell. If the obtained V2X resource of the second cell is a dedicated V2X resource, the terminal device may use the resource directly, or if the obtained V2X resource of the second cell is a resource pool, the terminal device may first use a special transmission resource pool of the second cell to transmit data, perform sensing on the transmission resource pool of the second cell, and use the transmission resource pool of the second cell after obtaining the sensing result.

It should be noted that the V2X resource of the first cell and the V2X resource of the second cell may refer to the same resource if both are dedicated resources, and if both are resource pools, the V2X resource of the first cell may include at least one of a transmission resource pool of the first cell, a reception resource pool of the first cell, or a special transmission resource pool of the first cell, and the V2X resource of the second cell may include at least one of a transmission resource pool of the second cell, a reception resource pool of the second cell, or a special transmission resource pool of the second cell, and no limitation is made as to which resource pool or pools are included in the first cell, and no limitation is also made as to which resource pool or pools are included in the second cell. Then, the resource pool of the first cell that the second cell determined by the terminal device is not applicable to may be the same resource pool as the resource pool of the second cell used under the second cell, for example, if the terminal device determines that the second cell is not applicable to the receiving resource pool of the first cell, the receiving resource pool of the second cell is used under the second cell; or, the resource pool of the first cell for which the second cell is not applicable, which is determined by the terminal device, may be a different resource pool from the resource pool of the second cell used in the second cell, for example, if the terminal device determines that the second cell is not applicable to the transmission resource pool of the first cell, the terminal device uses the special transmission resource pool of the second cell in the second cell and performs sending on the transmission resource pool of the second cell, and then uses the transmission resource pool of the second cell until the sending result of the transmission resource pool of the second cell is obtained.

If the terminal device cannot determine whether the frequency of the second cell or the second cell is suitable for the V2X resource, the processing manner of the terminal device may be similar to that when it is determined that the frequency of the second cell or the second cell is not suitable for the V2X resource, which is not described in detail.

In this embodiment of the present application, the network device may indicate, through the first message, the cell or the frequency to which the V2X resource is applicable, so that when the terminal device performs cell reselection or cell handover, it may be determined which cells or frequencies continue to apply the V2X resource, and if the terminal device reselects or switches to these cells, the terminal device may directly use the V2X resource without acquiring the V2X resource of a new cell, and does not need to perform sensing on the V2X resource any more, thereby reducing an operation process of the terminal device, saving power consumption of the terminal device, and improving transmission efficiency.

In order to solve the same technical problem, an embodiment of the present application provides a second resource allocation method, please refer to fig. 7A, which is a flowchart of the method. In the following description, the method is applied to the network architecture shown in fig. 5 as an example. In addition, the method may be performed by two communication devices, for example, a third communication device and a fourth communication device. The third communication device may be a network device or a communication device capable of supporting the network device to implement the functions required by the method, or may be a terminal device or a communication device capable of supporting the terminal device to implement the functions required by the method, or may be other communication devices, such as a system on chip. Similarly, the fourth communication device may be a network device or a communication device capable of supporting the network device to implement the functions required by the method, or may be a terminal device or a communication device capable of supporting the terminal device to implement the functions required by the method, and of course, may also be other communication devices, such as a chip system. The third communication device and the fourth communication device are not limited to be implemented, for example, the two communication devices may be implemented in the same form, for example, both may be implemented in the form of a device, or the two communication devices may also be implemented in different forms, for example, the third communication device is implemented in the form of a device, the fourth communication device is implemented in the form of a system on a chip, and so on. The network device is, for example, a base station.

For convenience of introduction, in the following, the method is performed by the network device and the terminal device as an example, that is, the third communication device is the network device, and the fourth communication device is the terminal device as an example. Since this embodiment is applied to the network architecture shown in fig. 5 as an example, the network device described below may be the network device in the network architecture shown in fig. 5, and the terminal device described below may be the terminal device 1 or the terminal device 2 in the network architecture shown in fig. 5, and if the terminal device described below is the terminal device 1 in the network architecture shown in fig. 5, the other terminal device described below may be the terminal device 2 in the network architecture shown in fig. 5, or if the terminal device described below is the terminal device 2 in the network architecture shown in fig. 5, the other terminal device described below may be the terminal device 1 in the network architecture shown in fig. 5. In addition, for the sake of simplicity of description, the V2X terminal device is also referred to simply as a terminal device hereinafter.

S71, the network device generates a first message, where the first message is used to indicate M pieces of neighboring cell information of a first cell, and the first message is further used to indicate whether V2X resources of a cell corresponding to each piece of neighboring cell information in the M pieces of neighboring cell information are the same as V2X resources of the first cell, or the first message is used to indicate N pieces of neighboring frequency information of a frequency of the first cell, and the first message is further used to indicate whether V2X resources of the frequency corresponding to each piece of neighboring frequency information in the N pieces of neighboring frequency information are the same as V2X resources of the frequency of the first cell; m and N are both positive integers.

As an embodiment, the first message may further include the V2X resource of the first cell. The saving of signaling overhead is facilitated by a message that includes both the V2X resource and the indication information.

Alternatively, as another embodiment, the first message may not include the V2X resource of the first cell, and instead, the network device may also send the second message at the first cell, with the second cell including the V2X resource. Therefore, the V2X resource and the indication information can be sent in different messages, and the transmission reliability is improved.

For example, the first message includes indication information indicating whether V2X resources of a cell corresponding to each of the M neighbor information are the same as V2X resources of the first cell, or indicating whether V2X resources of a frequency corresponding to each of the N neighbor information are the same as V2X resources of a frequency of the first cell, which may be implemented by the indication information. For example, if the first message is used to indicate M neighbor information of the first cell, the indication information is used to indicate whether V2X resources of a cell corresponding to each of the M neighbor information are the same as V2X resources of the first cell, or if the first message is used to indicate N neighbor information of a frequency of the first cell, the indication information is used to indicate whether V2X resources of the frequency corresponding to each of the N neighbor information are the same as V2X resources of the frequency of the first cell.

The V2X resource of the first cell may include a V2X resource pool for at least one terminal device, or a dedicated V2X resource for a terminal device, which is the terminal device receiving the first message. Wherein the V2X resource pool comprises at least one of the following: a transmit resource pool for providing V2X transmit resources, a receive resource pool for providing V2X receive resources, and a special transmit resource pool for providing V2X transmit resources. The dedicated V2X resource is a V2X resource dedicated for use by one terminal device that does not have to compete with other terminal devices, the dedicated V2X resource may include a transmission resource for which the terminal device does not have to transmit but may be used directly and/or a reception resource.

The first message may be used to indicate M neighbor cell information of the first cell or indicate N neighbor frequency information of the first cell. In addition, the first message may further include indication information. This is described in the following cases.

1. If the first message is used to indicate M neighbor information of the first cell, the indication information may indicate whether V2X resources of the cell corresponding to each of the M neighbor information are the same as V2X resources of the current cell.

For example, the indication information may be implemented by a list, where the list includes part of or all of M pieces of neighboring cell information, where, in the M pieces of neighboring cell information, all of the M pieces of neighboring cell information are neighboring cells that use V2X resources that are the same as V2X resources of the current cell, and all of the M pieces of neighboring cell information are neighboring cells that are not included in the list, and all of the M pieces of neighboring cell information are neighboring cells that use V2X resources that are different from V2X resources of the current cell, so that the indication information may indicate whether V2X resources of a cell corresponding to each piece of the M pieces of neighboring cell information are the same as V2X resources of the current cell; or, in the case that all the M pieces of neighboring cell information included in the list are neighboring cells whose used V2X resources are different from the V2X resources of the current cell, all the M pieces of neighboring cell information that are not included in the list may be neighboring cells whose used V2X resources are the same as the V2X resources of the current cell, or may be neighboring cells whose used V2X resources are not determined to be the same as the V2X resources of the current cell.

Or the indication information may also be implemented in other manners, for example, the indication information includes at least one piece of sub information, where the at least one piece of sub information corresponds to at least one piece of neighboring cell information in the M pieces of neighboring cell information, and the neighboring cell information and the sub information are in one-to-one correspondence. For example, in the first message, a piece of sub-information may be added to each of at least one of the M pieces of neighbor information, where one piece of sub-information occupies, for example, 1 bit, and the sub-information is used to indicate that the V2X resource used by the corresponding neighbor is the same as the V2X resource of the first cell, or to indicate that the V2X resource used by the corresponding neighbor is different from the V2X resource of the first cell. For example, the sub information is used to indicate that V2X resources used by the corresponding neighboring cell are the same as V2X resources of the first cell, then, of the M pieces of neighboring cell information, if V2X resources used by neighboring cell information to which the sub information is added are the same as V2X resources of the first cell, if V2X resources used by neighboring cell information to which the sub information is not added are different from V2X resources of the first cell; or the sub information is used to indicate that the V2X resource used by the corresponding neighboring cell is different from the V2X resource of the first cell, so that, in the M pieces of neighboring cell information, if the V2X resource used by the neighboring cell information to which the sub information is added is different from the V2X resource of the first cell, and if the V2X resource used by the neighboring cell information to which the sub information is not added is the same as the V2X resource of the first cell, or it may be considered that whether the V2X resource used by the neighboring cell information is not the same as the V2X resource of the first cell; alternatively, the V2X resource used by the corresponding neighboring cell whose sub information is 1 may be the same as the V2X resource of the first cell, and the V2X resource used by the neighboring cell whose sub information is 0 may be considered to be different from the V2X resource of the first cell, or it may be considered that the V2X resource used by the neighboring cell information is not certain to be the same as the V2X resource of the first cell.

Of course, the indication information may also be implemented in other ways, and is not limited specifically.

2. For example, if the first message is used to indicate N adjacent channel information of the first cell, the indication information may indicate whether V2X resources of the cell corresponding to each of the N adjacent channel information are the same as V2X resources of the first cell. For example, the indication information may be implemented by a list, where the list includes part of or all of the N pieces of adjacent frequency information, where any piece of adjacent frequency information included in the list is an adjacent frequency using V2X resources that are the same as V2X resources of the first cell, and any piece of adjacent frequency information that is not included in the list is an adjacent frequency using V2X resources that are different from V2X resources of the first cell, so that the indication information may indicate whether V2X resources under the adjacent frequency corresponding to each piece of adjacent frequency information in the N pieces of adjacent frequency information are the same as V2X resources of the first cell; or, in the case that any adjacent frequency information included in the N adjacent frequency information is an adjacent frequency using a different V2X resource from the V2X resource of the first cell, in this case, any adjacent frequency information not included in the N adjacent frequency information in the list may be an adjacent frequency using the same V2X resource as the V2X resource of the first cell, or may be an adjacent frequency not using the same V2X resource as the V2X resource of the first cell.

Or the indication information may also be implemented in other manners, for example, the indication information includes at least one piece of sub information, where the at least one piece of sub information corresponds to at least one piece of adjacent frequency information in the N pieces of adjacent frequency information, and the adjacent frequency information and the sub information are in one-to-one correspondence. For example, in the first message, one piece of sub information may be added for each piece of adjacent frequency information in at least one piece of adjacent frequency information of the N pieces of adjacent frequency information, where one piece of sub information occupies, for example, 1 bit, and the sub information is used to indicate that V2X resources used by the corresponding adjacent frequency are the same as V2X resources of the first cell, or to indicate that V2X resources used by the corresponding adjacent frequency are different from V2X resources of the first cell. For example, the sub information is used to indicate that V2X resources used by the corresponding adjacent frequency are the same as V2X resources of the first cell, then of the N adjacent frequency information, V2X resources used by any adjacent frequency information to which the sub information is added are the same as V2X resources of the first cell, and V2X resources used by any adjacent frequency information to which the sub information is not added are different from V2X resources of the first cell; or, the sub information is used to indicate that the V2X resource used by the corresponding adjacent frequency is different from the V2X resource of the first cell, so that, in the N pieces of adjacent frequency information, if the V2X resource used by the adjacent frequency information to which the sub information is added is different from the V2X resource of the first cell, and if the V2X resource used by the adjacent frequency information to which the sub information is not added is considered to be the same as the V2X resource of the first cell, or it may also be considered that whether the V2X resource used by the adjacent frequency information is not definitely the same as the V2X resource of the first cell; alternatively, the V2X resource used by the adjacent channel corresponding to the sub information 1 is the same as the V2X resource of the first cell, and the V2X resource used by the adjacent channel corresponding to the sub information 0 may be considered to be different from the V2X resource of the first cell, or it may be considered that the V2X resource used by these adjacent channel information is not certain to be the same as the V2X resource of the first cell.

The first message is, for example, a system message, the system message itself may carry the neighboring cell information and/or the neighboring frequency information of the first cell, and the indication information may be directly added to the system message, which is relatively simple to implement. Of course, other implementations of the first message are possible, and are not limited in particular. If the network device also sends a second message, the second message is, for example, a system message, or may also be dedicated signaling or the like. For example, after the network device generates the second message, if the second message is dedicated signaling, the network device sends the second message in the first cell, where "send" may be understood as unicast, or if the second message is a system message, the network device broadcasts the second message in the first cell, and the terminal device may receive the second message from the network device in the first cell. The network device may send the first message and then send the second message, or may send the second message and then send the first message, or may send the first message and the second message at the same time.

The first cell may be a cell under the network device, for example, if the first message is a broadcast message (e.g., a system message), then the network device may broadcast the system message in multiple cells, and the first cell is one of the multiple cells, or the network device may broadcast the system message in only one cell, and the first cell is the cell.

And S72, the network device sends the first message, and the terminal device receives the first message from the network device.

If the first message is a system message, the network device may specifically broadcast the first message. For example, the network device may send the first message in the first cell, and the terminal device receives the first message from the network device in the first cell. If the network device also sends the second message, the network device may also send the second message in the first cell where the terminal device receives the second message from the network device.

S73, the terminal device determines, according to the first message, M pieces of neighboring cell information of the first cell, and determines whether a V2X resource of a cell corresponding to each piece of neighboring cell information of the M pieces of neighboring cell information is the same as a V2X resource of the first cell, or determines, according to the first message, N pieces of neighboring frequency information of a frequency of the first cell, and determines whether a V2X resource of the frequency corresponding to each piece of neighboring frequency information of the N pieces of neighboring frequency information is the same as a V2X resource of the first cell.

As an embodiment, if the first message is used to indicate M neighbor information of the first cell, the indication information may indicate whether V2X resources of the cell corresponding to each of the M neighbor information are the same as V2X resources of the first cell. For example, the indication information is implemented by a list, where the list includes part of or all of the M pieces of neighboring cell information, and the terminal device may determine that all of the M pieces of neighboring cell information included in the list are neighboring cells using V2X resources that are the same as V2X resources of the first cell, and all of the M pieces of neighboring cell information not included in the list are neighboring cells using V2X resources that are different from V2X resources of the first cell; or, the terminal device may determine that, of the M pieces of neighboring cell information, any neighboring cell information included in the list is a neighboring cell in which the used V2X resource is different from the V2X resource of the first cell, and in this case, any neighboring cell information not included in the list in the M pieces of neighboring cell information may be a neighboring cell in which the used V2X resource is the same as the V2X resource of the first cell, or may be a neighboring cell in which the V2X resource that is not used in an uncertain manner is the same as the V2X resource of the first cell.

Or the indication information is implemented by means of sub information. For example, the indication information includes at least one piece of sub information, and the at least one piece of sub information corresponds to at least one piece of neighbor information in the M pieces of neighbor information, where the neighbor information and the sub information correspond to each other one to one. For example, in the first message, each neighbor information in at least one neighbor information of the M neighbor information corresponds to a sub-information, and the sub-information is used to indicate that the V2X resource used by the corresponding neighbor is the same as the V2X resource of the first cell, or to indicate that the V2X resource used by the corresponding neighbor is different from the V2X resource of the first cell. For example, if the sub information is used to indicate that the V2X resource used by the corresponding neighboring cell is the same as the V2X resource of the first cell, the terminal device may determine that, of the M pieces of neighboring cell information, the V2X resource used by the neighboring cell information to which the sub information is added is the same as the V2X resource of the first cell, and the V2X resource used by the neighboring cell information to which the sub information is not added is different from the V2X resource of the first cell; or, the sub information is used to indicate that V2X resources used by the corresponding neighboring cell are different from V2X resources of the first cell, the terminal device may determine that, in the M pieces of neighboring cell information, if V2X resources used by the neighboring cell information to which the sub information is added are different from V2X resources of the first cell, and if V2X resources used by the neighboring cell information to which the sub information is not added are considered to be the same as V2X resources of the first cell, or may also consider that whether V2X resources used by the neighboring cell information are not determined to be the same as V2X resources of the first cell; or, at least one neighbor cell information is all neighbor cell information in the M neighbor cell information, that is, each neighbor cell information in the M neighbor cell information corresponds to a sub-information, one sub-information is used to indicate that V2X resources of the corresponding neighbor cell information are the same as or different from V2X resources of the first cell, for example, the sub information may indicate different results by different values, for example, one sub information is implemented by 1 bit, if the value of the 1 bit is '1', it indicates that the V2X resource of the corresponding neighbor information is the same as the V2X resource of the first cell, if the value of the 1 bit is "0", it indicates that the V2X resource of the corresponding neighboring cell information is different from the V2X resource of the first cell, the terminal device may determine, according to the sub information corresponding to each of the M neighboring cell information, whether the V2X resource of the corresponding neighboring cell information is the same as or different from the V2X resource of the first cell.

As another embodiment, if the first message is used to indicate N adjacent channel information of the first cell, the indication information may indicate whether V2X resources of a cell corresponding to each of the N adjacent channel information are the same as V2X resources of the first cell. For example, the indication information is implemented by a list, where the list includes part of or all of the N pieces of adjacent frequency information, and the terminal device may determine that all of the N pieces of adjacent frequency information included in the list are adjacent frequencies using V2X resources that are the same as V2X resources of the first cell, and all of the N pieces of adjacent frequency information not included in the list are adjacent frequencies using V2X resources that are different from V2X resources of the first cell; or the terminal device may determine that any adjacent channel information included in the N adjacent channel information is an adjacent channel using a different V2X resource from the V2X resource of the first cell, in which case, any adjacent channel information not included in the N adjacent channel information in the list may be an adjacent channel using the same V2X resource as the V2X resource of the first cell, or may be an adjacent channel not determining whether the used V2X resource is the same as the V2X resource of the first cell.

Or the indication information may also be implemented by way of sub information. For example, the indication information includes at least one piece of sub information, and the at least one piece of sub information corresponds to at least one piece of adjacent channel information in the N pieces of adjacent channel information, where the adjacent channel information and the sub information correspond to each other one to one. For example, in the first message, each of at least one of the N adjacent channel information corresponds to one piece of sub information, and the sub information is used to indicate that V2X resources used by the corresponding adjacent channel are the same as V2X resources of the first cell, or to indicate that V2X resources used by the corresponding adjacent channel are different from V2X resources of the first cell. For example, if the sub information is used to indicate that the V2X resource used by the corresponding adjacent channel is the same as the V2X resource of the first cell, the terminal device may determine that, of the N adjacent channel information, the V2X resource used by any adjacent channel information to which the sub information is added is the same as the V2X resource of the first cell, and the V2X resource used by any adjacent channel information to which the sub information is not added is different from the V2X resource of the first cell; or, the sub information is used to indicate that the V2X resource used by the corresponding adjacent frequency is different from the V2X resource of the first cell, the terminal device may determine that, of the N pieces of adjacent frequency information, the V2X resource used by any piece of adjacent frequency information to which the sub information is added is different from the V2X resource of the first cell, and the V2X resource used by any piece of adjacent frequency information to which the sub information is not added may be considered to be the same as the V2X resource of the first cell, or may also consider that the V2X resource used by these pieces of adjacent frequency information is not determined to be the same as the V2X resource of the first cell; or, at least one adjacent channel information is all adjacent channel information in the N adjacent channel information, that is, each adjacent channel information in the N adjacent channel information corresponds to a sub-information, one sub-information is used to indicate that the V2X resource of the corresponding adjacent channel information is the same as or different from the V2X resource of the first cell, for example, the sub information may indicate different results by different values, for example, one sub information is implemented by 1 bit, if the value of the 1 bit is '1', it indicates that the V2X resource of the corresponding adjacent channel information is the same as the V2X resource of the first cell, if the value of the 1 bit is "0", indicating that the V2X resource of the corresponding adjacent channel information is different from the V2X resource of the first cell, the terminal device may determine, according to the sub information corresponding to each of the N adjacent channel information, whether the V2X resource of the corresponding adjacent channel information is the same as or different from the V2X resource of the first cell.

As an embodiment, when performing cell reselection or cell handover subsequently, the terminal device may determine whether the V2X resource of the first cell is applicable to a second cell, where the second cell refers to a cell after cell reselection or cell handover, and for example, the second cell may also be referred to as a target cell.

For example, if the terminal device may determine, according to the indication information, whether the V2X resource of the cell corresponding to each of the at least one of the M pieces of neighbor information is the same as the V2X resource of the first cell, the terminal device may determine whether the second cell is a cell corresponding to one of the at least one of the M pieces of neighbor information. If the terminal equipment determines that the V2X resource of the cell corresponding to each neighbor cell information in at least one neighbor cell information in the M neighbor cell information is the same as the V2X resource of the first cell and the second cell is the cell corresponding to one neighbor cell information in the at least one neighbor cell information according to the indication information, the terminal equipment determines that the second cell is suitable for the V2X resource of the first cell; or, if the terminal device determines, according to the indication information, that the V2X resource of the cell corresponding to each of the at least one of the M pieces of neighboring cell information is the same as the V2X resource of the first cell, and the second cell is not a cell corresponding to any of the at least one of the neighboring cell information, the terminal device determines that the second cell is not applicable to the V2X resource of the first cell; or, if the terminal device determines, according to the indication information, that the V2X resource of the cell corresponding to each of the at least one of the M pieces of neighboring cell information is different from the V2X resource of the first cell, and the second cell is a cell corresponding to one of the at least one of the neighboring cell information, the terminal device determines that the second cell is not applicable to the V2X resource of the first cell; or, if the terminal device determines, according to the indication information, that the V2X resource of the cell corresponding to each of the at least one of the M pieces of neighboring cell information is different from the V2X resource of the first cell, and the second cell is not a cell corresponding to any of the at least one of the neighboring cell information, the terminal device may determine that the second cell is suitable for the V2X resource of the first cell, or may not determine whether the second cell is suitable for the V2X resource of the first cell; or, if the terminal device determines that the second cell is a cell corresponding to one of the M pieces of neighboring cell information, and the V2X resource of the second cell is the same as the V2X resource of the first cell (that is, each piece of neighboring cell information of the M pieces of neighboring cell information corresponds to one piece of sub-information, one piece of sub-information may indicate whether the V2X resource of the corresponding neighboring cell information is the same as the V2X resource of the first cell, and the sub-information corresponding to the neighboring cell information of the M pieces of neighboring cell information indicates that the V2X resource of the neighboring cell information is the same as the V2X resource of the first cell), the terminal device determines that the second cell is suitable for the V2X resource of the first cell; or, if the terminal device determines that the second cell is a cell corresponding to one of the M pieces of neighboring cell information, and the V2X resource of the second cell is different from the V2X resource of the first cell (that is, each piece of neighboring cell information of the M pieces of neighboring cell information corresponds to a piece of sub-information, one piece of sub-information may indicate whether the V2X resource of the corresponding neighboring cell information is the same as the V2X resource of the first cell, and the sub-information corresponding to the neighboring cell information of the M pieces of neighboring cell information indicates that the V2X resource of the neighboring cell information is different from the V2X resource of the first cell), the terminal device determines that the second cell is not suitable for the V2X resource of the first cell; or, if each piece of neighboring cell information in the M pieces of neighboring cell information corresponds to one piece of sub information, where one piece of sub information may indicate whether a V2X resource of the corresponding neighboring cell information is the same as a V2X resource of the first cell, and the terminal device determines that the second cell is not a cell corresponding to any piece of neighboring cell information in the M pieces of neighboring cell information, the terminal device does not determine whether the second cell is suitable for a V2X resource of the first cell.

Alternatively, if the terminal device may determine whether the V2X resource under the adjacent frequency corresponding to each of the at least one of the N adjacent frequency information is the same as the V2X resource of the first cell according to the indication information, the terminal device may determine whether the frequency of the second cell is a frequency corresponding to one of the at least one of the N adjacent frequency information. If the terminal equipment determines that the V2X resource of the frequency corresponding to each adjacent channel information in at least one adjacent channel information in the N adjacent channel information is the same as the V2X resource of the first cell and the frequency of the second cell is the frequency corresponding to one adjacent channel information in the at least one adjacent channel information according to the indication information, the terminal equipment determines that the frequency of the second cell is suitable for the V2X resource of the first cell and can also be considered as determining that the second cell is suitable for the V2X resource of the first cell; or, if the terminal device determines, according to the indication information, that the V2X resource of the frequency corresponding to each of at least one of the N adjacent frequency information is the same as the V2X resource of the first cell, and the frequency of the second cell is not the frequency corresponding to any adjacent frequency information in the at least one adjacent frequency information, the terminal device determines that the frequency of the second cell is not applicable to the V2X resource of the first cell, that is, determines that the second cell is not applicable to the V2X resource of the first cell; or, if the terminal device determines, according to the indication information, that the V2X resource of the frequency corresponding to each of at least one of the N adjacent frequency information is different from the V2X resource of the first cell, and the frequency of the second cell is the frequency corresponding to one of the at least one adjacent frequency information, the terminal device determines that the frequency of the second cell is not applicable to the V2X resource of the first cell, that is, determines that the second cell is not applicable to the V2X resource of the first cell; or, if the terminal device determines, according to the indication information, that the V2X resource of the frequency corresponding to each of at least one of the N pieces of adjacent frequency information is different from the V2X resource of the first cell, and the second cell is not a cell corresponding to any adjacent frequency information in the at least one piece of adjacent frequency information, the terminal device may determine that the frequency of the second cell is applicable to the V2X resource of the first cell, that is, determine that the second cell is applicable to the V2X resource of the first cell, or may also determine whether the frequency of the second cell is applicable to the V2X resource of the first cell, that is, determine whether the second cell is applicable to the V2X resource of the first cell; or, if the terminal device determines that the frequency of the second cell is a frequency corresponding to one of the N pieces of adjacent frequency information, and the V2X resource of the frequency of the second cell is the same as the V2X resource of the first cell (that is, each of the N pieces of adjacent frequency information corresponds to one piece of sub-information, one piece of sub-information may indicate whether the V2X resource of the corresponding adjacent frequency information is the same as the V2X resource of the first cell, and the sub-information corresponding to the adjacent frequency information corresponding to the frequency of the second cell in the N pieces of adjacent frequency information indicates that the V2X resource of the adjacent frequency information is the same as the V2X resource of the first cell), the terminal device determines that the frequency of the second cell is applicable to the V2X resource of the first cell, that is, determines that the second cell is applicable to the V2X resource of the first cell; or, if the terminal device determines that the frequency of the second cell is a frequency corresponding to one of the N pieces of adjacent frequency information, and the V2X resource of the frequency of the second cell is different from the V2X resource of the first cell (that is, each of the N pieces of adjacent frequency information corresponds to one piece of sub-information, one piece of sub-information may indicate whether the V2X resource of the corresponding adjacent frequency information is the same as the V2X resource of the first cell, and the sub-information corresponding to the adjacent frequency information corresponding to the frequency of the second cell in the N pieces of adjacent frequency information indicates that the V2X resource of the adjacent frequency information is different from the V2X resource of the first cell), the terminal device determines that the frequency of the second cell is not applicable to the V2X resource of the first cell, that is, determines that the second cell is not applicable to the V2X resource of the first cell; or, if each of the N adjacent frequency information corresponds to one piece of sub-information, one piece of sub-information may indicate whether the V2X resource of the corresponding adjacent frequency information is the same as the V2X resource of the first cell, and the terminal device determines that the second cell is not a cell in the frequency of any adjacent frequency information of the N adjacent frequency information, the terminal device does not determine whether the second cell applies the V2X resource of the first cell.

If the terminal device determines that the second cell or the frequency of the second cell is suitable for the V2X resource of the first cell, the terminal device may continue to use the V2X resource of the first cell after reselecting or handing over to the second cell, without acquiring the V2X resource of the second cell, which reduces the process of acquiring the V2X resource by the terminal device. Moreover, if the V2X resource of the first cell is the V2X resource pool, the terminal device does not need to sense the transmission resource pool in the V2X resource pool after reselecting or switching to the second cell, so as to reduce the power consumption of the terminal device, and the terminal device does not need to use a special transmission resource pool in the V2X resource pool, but can directly use the transmission resource pool, thereby reducing the possible collision between the terminal device and other terminal devices when selecting resources.

Referring again to FIG. 7B, the general process of the embodiment of FIG. 7A can be seen by FIG. 7B. Fig. 7B takes the first message as the system message and the first message is used to indicate the M pieces of neighboring cell information of the first cell as an example, so fig. 7B is the network device broadcasting the first message. The first message is also used to indicate whether V2X resources of the cell corresponding to each of the M neighbor information are the same as V2X resources of the first cell. Then the terminal device, upon handover or reselection to the second cell, does not need to obtain the V2X resource of the second cell but continues to use the V2X resource of the first cell if the second cell is the cell indicated by the first message that has the same corresponding V2X resource as the V2X resource of the first cell.

Alternatively, if the second cell or the frequency of the second cell does not apply to the V2X resource of the first cell, the terminal device may acquire and use the V2X resource of the second cell after reselecting or handing over to the second cell. For example, the terminal device may obtain the V2X resource of the second cell through a system message sent by the second cell, or may obtain the V2X resource of the second cell through a handover command sent by the first cell, or may also obtain the V2X resource configured by the second cell after accessing the second cell. If the obtained V2X resource of the second cell is a dedicated V2X resource, the terminal device may use the resource directly, or if the obtained V2X resource of the second cell is a resource pool, the terminal device may first use a special transmission resource pool of the second cell to transmit data, perform sensing on the transmission resource pool of the second cell, and use the transmission resource pool of the second cell after obtaining the sensing result.

If the terminal device cannot determine whether the frequency of the second cell or the second cell is applicable to the V2X resource of the first cell, the processing manner of the terminal device may be similar to the processing manner when the frequency of the second cell or the second cell is not applicable to the V2X resource of the first cell, which is not described herein again.

In order to solve the same technical problem, an embodiment of the present application provides a third resource allocation method, please refer to fig. 8A, which is a flowchart of the method. In the method, the technical problem is solved by the identification of the area corresponding to the V2X resource (or the identification of the area corresponding to the cell or the frequency). In the following description, the method is applied to the network architecture shown in fig. 5 as an example. In addition, the method may be performed by two communication devices, for example, a fifth communication device and a sixth communication device. The fifth communication device may be a network device or a communication device capable of supporting the network device to implement the functions required by the method, or may be a terminal device or a communication device capable of supporting the terminal device to implement the functions required by the method, and of course, may also be other communication devices, such as a chip system. Similarly, the sixth communication device may be a network device or a communication device capable of supporting the network device to implement the functions required by the method, or may be a terminal device or a communication device capable of supporting the terminal device to implement the functions required by the method, and may also be other communication devices, such as a chip system. The implementation manners of the fifth communication device and the sixth communication device are not limited, for example, the two communication devices may be implemented in the same form, for example, both are implemented in the form of a device, or the two communication devices may also be implemented in different forms, for example, the fifth communication device is implemented in the form of a device, the sixth communication device is implemented in the form of a system-on-chip, and so on. The network device is, for example, a base station.

For convenience of introduction, in the following, the method is performed by the network device and the terminal device as an example, that is, the fifth communication device is the network device, and the sixth communication device is the terminal device as an example. Since this embodiment is applied to the network architecture shown in fig. 5 as an example, the network device described below may be the network device in the network architecture shown in fig. 5, and the terminal device described below may be the terminal device 1 or the terminal device 2 in the network architecture shown in fig. 5, and if the terminal device described below is the terminal device 1 in the network architecture shown in fig. 5, the other terminal device described below may be the terminal device 2 in the network architecture shown in fig. 5, or if the terminal device described below is the terminal device 2 in the network architecture shown in fig. 5, the other terminal device described below may be the terminal device 1 in the network architecture shown in fig. 5. In addition, for the sake of simplicity of description, the V2X terminal device is also referred to simply as a terminal device hereinafter.

S81, the network equipment generates a first message, wherein the first message comprises a first identification of V2X resources of the first cell, and the first identification is used for indicating an area where the V2X resources of the first cell are applicable.

The V2X resources of the first cell may comprise a V2X resource pool for at least one terminal device application, or comprise dedicated V2X resources for a terminal device, that is, a terminal device receiving the first message. Wherein the V2X resource pool comprises at least one of the following: a transmit resource pool for providing V2X transmit resources, a receive resource pool for providing V2X receive resources, and a special transmit resource pool for providing V2X transmit resources.

In the NR system, some SIBs of some cells may be the same, so to avoid repeated requests of the terminal device in each cell, an area specific SIB (area specific SIB) is defined, and different areas may be divided, where each area corresponds to an area identity number (area ID), that is, as long as the area is within a certain area, the area specific SIB in the area is valid. After entering a cell, if it is determined that the area ID corresponding to the cell is the same as the area ID of the previous cell, it indicates that the area-specific SIB has not changed, and the request does not need to be repeated.

In this embodiment of the present application, the area division of the V2X resource and the area division of the area-specific SIB may also be different areas, each area corresponds to an identifier of an area, for example, an area ID, and the area ID may be globally unique (i.e., the ID is also unique between different operators), may be geographically unique (i.e., the ID needs to be unique in a certain geographic location, such as beijing), or may be unique within one operator, and the area corresponds to the V2X resource (or may also be considered as the area corresponds to a cell or a frequency, or the area corresponds to an SIB corresponding to the V2X resource, where the SIB for configuring the V2X resource corresponds to the V2X resource). After the terminal device enters a cell, if it is determined that the area ID corresponding to the cell is the same as the area ID of the previous cell, it indicates that the V2X resources in the two regions are the same, and the terminal device does not need to request the SIB corresponding to the V2X resource in the new cell, that is, does not need to reacquire the V2X resource in the new cell. For example, the V2X resource of the original cell is a resource pool, and the terminal device does not need to send the transmission resource pool in the resource pool, but can directly use the transmission resource pool to transmit data, which reduces the processing procedure of the terminal device, saves the power consumption of the terminal device, and does not need to use a special transmission resource pool, reduces the probability of collision between the terminal device and other terminal devices when selecting resources, and also reduces the possibility of transmission interruption. Moreover, the method of setting the area ID is simpler than the method of setting the indication information, and is more advantageous for saving the transmission overhead.

In the embodiment of the present application, for example, an area ID corresponding to the first cell (or an area ID corresponding to the V2X resource of the first cell) is referred to as a first identifier, and the first identifier may indicate an area to which the V2X resource of the first cell is applicable. In the embodiment of the present application, the partition rule of the region corresponding to the first identifier may be the same as or different from the partition rule of the region corresponding to the non-V2X resource, or it is understood that the SIB for configuring the V2X resource is different from the region-specific SIB in the current NR technology.

The partition rule of the region corresponding to the first identifier may be the same as or different from the partition rule of the region corresponding to the non-V2X resource, that is, the area ID in the NR technology may be multiplexed, and the area ID in the NR technology is not for the V2X resource, but the embodiment of the present application may multiplex such a manner that the area ID corresponds to the V2X resource, or corresponds to an SIB for configuring the V2X resource. Then, the area ID in the embodiment of the present application corresponds to the same area as the area ID existing in the NR technique, for example, the area IDs 1 all correspond to the area 1, the area IDs 2 all correspond to the area 2, and so on.

Or, the area corresponding to the area ID in the current NR technology has a large range, and if the same resource pool is used in a large area, the resource utilization rate of some cells in the area may be low. For example, the area includes 7 cells, cell 1, cell 2 and cell 3 are busy, and cell 4, cell 5 and cell 6 are idle, but these cells all use the same resource pool, and obviously the resource utilization rate is not high for cell 4, cell 5 and cell 6. In view of this, in the embodiment of the present application, instead of multiplexing the area and the area ID divided in the current NR technique, the area may be newly divided, and the area ID may be newly assigned to the divided area. In this case, the area ID in the embodiment of the present application may correspond to the same area as or different from an area ID existing in the NR technology.

In addition, the dedicated resources and the transmission resource pool, the reception resource pool, and the special resource pool included in the resource pool may apply the same region division rule, that is, the corresponding regions are the same for both the transmission resource pool and the reception resource pool as long as the identifiers of the regions are the same. Alternatively, the sending resource pool, the receiving resource pool, and the special resource pool included in the dedicated resource and the resource pool may be adapted to different region partition rules, for example, the sending resource pool is adapted to the new region partition rule provided in the embodiment of the present application, and the receiving resource pool may continue to reuse the existing region partition rule in the NR technique. For example, different V2X resources (sending resource pool, receiving resource pool, special resource pool, dedicated resource) may correspond to multiple area IDs (e.g., sending resource pool corresponds to area ID1, receiving resource pool corresponds to area ID 2). After entering a cell, the terminal device determines that the area ID1 corresponding to a certain V2X resource changes, and then the terminal device only acquires the resource, and for the area ID2 that does not change, the terminal device does not need to acquire the corresponding V2X resource again in the new cell. For example, the V2X resource of the original cell is a resource pool, area ID1 corresponds to a reception resource pool, and area ID2 corresponds to a transmission resource pool. For the receiving resource pool, it is necessary to configure the positions of all the sending resources that can be received by the current region, so that the terminal device may receive the V2X information sent by all other peripheral terminal devices, and if the sending resource pools of multiple cells are the same, the receiving resource pool configured by the cell located in the center of the region does not need to configure too many sending resource positions, but the cells located at the edge of the region need to configure the sending resource pool positions of multiple cells and other peripheral sending resource positions. If the area ID1 is changed, the terminal equipment acquires the V2X receiving resource, and if the area ID1 is not changed, the terminal equipment does not need to acquire the V2X receiving resource, so that the processing procedure of the terminal can be reduced, and the power consumption of the terminal equipment can be saved. If the area ID2 is not changed, the terminal equipment does not need to send the sending resource pool in the resource pool, but can directly use the sending resource pool to send data, so that the processing process of the terminal equipment is reduced, the power consumption of the terminal equipment is saved, a special sending resource pool is not needed, the probability of conflict between the terminal equipment and other terminal equipment when the terminal equipment selects resources is reduced, and the possibility of transmission interruption is also reduced. Moreover, the method of setting the area ID is simpler than the method of setting the indication information, and is more advantageous for saving the transmission overhead. The region division rules corresponding to different resources are not particularly limited.

S82, the network device sends the first message, and the terminal device receives the first message from the network device.

The first message may be a system message or may be dedicated signaling. Then, if the first message is a system message, the network device may be broadcasting the first message, for example, the network device broadcasts the first message in the first cell, and if the first message is dedicated signaling, the network device sends the first message, which may be understood as unicasting the first message, for example, the network device unicasting the first message in the first cell, and the terminal device receives the first message from the network device in the first cell.

If the network device further sends the second message, the second message may be a system message or may be dedicated signaling, and the type of the first message and the type of the second message may be the same, for example, the first message is a system message, but not the same system message, or the type of the first message and the type of the second message may be different, for example, the first message is a system message and the second message is dedicated signaling, or the first message is dedicated signaling and the second message is a system message, which is not limited in particular. After the network device generates the second message, if the second message is dedicated signaling, the network device sends the second message in the first cell, where "send" may be understood as unicast, or if the second message is a system message, the network device broadcasts the second message in the first cell, and the terminal device may receive the second message from the network device in the first cell. The network device may send the first message and then send the second message, or may send the second message and then send the first message, or may send the first message and the second message at the same time.

The first cell may be a cell under the network device, the first cell is a cell where the network device sends the dedicated signaling if the first message is the dedicated signaling, the first cell is one of a plurality of cells if the first message is a broadcast message (e.g., a system message) the network device may broadcast the system message in the plurality of cells, or the first cell is a cell if the network device may broadcast the system message in only one cell.

S83, the terminal device obtains the first identifier of the V2X resource of the first cell according to the first message, and the first identifier is used for indicating the applicable area of the V2X resource of the first cell.

For example, the terminal device may determine whether the V2X resource of the first cell is applicable after reselection or handover to the second cell when subsequently performing cell reselection or cell handover. The second cell refers to a cell after cell reselection or cell handover, and for example, the second cell may also be referred to as a target cell.

For example, when performing cell reselection or cell handover, the terminal device may obtain the identifier of the area to which the V2X resource of the second cell is applicable, so as to determine whether the identifier of the area to which the V2X resource of the second cell is applicable is the same as the first identifier. If the identity of the area to which the V2X resources of the second cell apply is the same as the first identity, the terminal device may continue to use the V2X resources of the first cell without obtaining the V2X resources of the second cell after reselecting or handing over to the second cell. For example, the V2X resource of the first cell is a V2X resource pool, the terminal device does not need to sense a transmission resource pool in the V2X resource pool, so as to reduce power consumption of the terminal device, and the terminal device does not need to use a special transmission resource pool in the V2X resource pool, but can directly use the transmission resource pool, so as to reduce possible conflicts between the terminal device and other terminal devices in resource selection.

Referring again to FIG. 8B, the general process of the embodiment of FIG. 8A can be seen through FIG. 8B. The network device sends a first message indicating a first identity of V2X resources of the first cell. Then the terminal device need not obtain the V2X resource of the second cell but continues to use the V2X resource of the first cell if the identity of the V2X resource of the second cell is the same as the first identity when handing over or reselecting to the second cell.

Alternatively, if the identity of the area to which the V2X resources of the second cell apply is different from the first identity, the terminal device may use the V2X resources of the second cell after cell reselection or cell handover to the second cell. For example, the terminal device may obtain the V2X resource of the second cell through a system message sent by the second cell, or may obtain the V2X resource of the second cell through a handover command sent by the first cell, or may also obtain the V2X resource configured by the second cell after accessing the second cell. If the obtained V2X resource of the second cell is a dedicated V2X resource, the terminal device may use the resource directly, or if the obtained V2X resource of the second cell is a resource pool, the terminal device may first use a special transmission resource pool of the second cell to transmit data, perform sensing on the transmission resource pool of the second cell, and use the transmission resource pool of the second cell after obtaining the sensing result.

The embodiment of the present application is not limited to the manner in which the terminal device obtains the identifier of the area to which the V2X resource of the second cell is applicable. For example, the terminal device may receive a third message, where the third message may include an identifier of an area to which the V2X resource of the second cell is applicable, and the third message is, for example, sent by the first cell, for example, a handover command, or may also be sent by the second cell, for example, a system message sent by the second cell, or a message such as an RRC reconfiguration sent by the second cell after the terminal device accesses the second cell. Or the terminal device may obtain the identification of the area to which the V2X resource of the second cell is applicable in other manners.

In addition, in this embodiment, the network device may further adjust an identifier of an area corresponding to one cell (or an identifier of an area corresponding to V2X resources of one cell), or may adjust an area corresponding to one cell (or an area corresponding to V2X resources of one cell). For example, the network device may adjust the identity of the V2X resource of the first cell to the second identity periodically or aperiodically according to the V2X load condition of the first cell, and the area indicated by the first identity may be different from the area indicated by the second identity. The adjusting, by the network device, the identifier of the V2X resource of the first cell to the second identifier according to the V2X load condition of the first cell may be that the network device adjusts the identifier of the V2X resource of the first cell to the second identifier when the V2X load of the first cell does not satisfy the load threshold. For example, the network device may determine a first cell V2X load, and may adjust the identity of the V2X resource of the first cell, e.g., to the second identity, if it is determined that the V2X load of the first cell does not satisfy the load threshold. The V2X load of the first cell does not satisfy the load threshold, which may mean that the load of the first cell is greater than (or equal to) the load threshold, or may also mean that the load of the first cell is less than (or equal to) the load threshold. The load threshold may be network device configured or may be specified by a protocol. Wherein the V2X load of the first cell may be used to indicate the number of terminal devices using V2X resources of the first cell and/or to indicate the amount of data transmitted using V2X resources of the first cell, in particular, the V2X load of the first cell may be used to indicate the number of terminal devices using V2X resources of the first cell or to indicate the amount of data transmitted using V2X resources of the first cell or to indicate the number of terminal devices using V2X resources of the first cell (vehicles and the like capable of communicating via V2X resources may be considered as V2X loads) and to indicate the amount of data transmitted using V2X resources of the first cell.

For example, for cell 1, the identifier of the corresponding area at the beginning is identifier 1, and the area corresponding to identifier 1 includes 7 cells. Then, if 3 of the 7 cells are busy and 4 other cells are idle, the network device may relocate the busy 3 cells to an area, and reset an identifier, for example, to identifier 2, for a new area where the 3 cells are located, where the corresponding SIB for configuring the V2X resource is different when the identifiers of the areas are different, and may configure a new V2X resource pool for the new area through the new SIB, or, when the identifiers of the areas are different, the configuration of the V2X resource in the system information is different, and may obtain the latest configuration by re-reading the system information. In addition, the 4 idle cells may continue to use the original identity 1, or the network device may also reset identities for the areas where the 4 cells are located, for example, the identity 3 is set, or a new configuration may be provided through a new SIB or updated system information to configure a new V2X resource pool for the areas where the 4 cells are located.

For example, the network device adjusts the identifier of the area corresponding to the first cell, or adjusts the identifier of the area corresponding to the V2X resource of the first cell, for example, from the first identifier to the second identifier, the network device may notify the terminal device. For example, the network device may send a third message to the terminal device, and the terminal device receives the third message from the network device, and the third message may indicate that the identifier of the V2X resource of the first cell is the second identifier, or the third message may indicate that the identifier of the V2X resource of the first cell is adjusted to the second identifier, that is, the third message may indicate only an adjustment result, or may also indicate an action of the adjustment and an adjustment result.

Then for a terminal device, if it is determined that the identity of the area corresponding to the V2X resource of the first cell changes from the first identity to the second identity, the terminal device may reacquire the V2X resource of the first cell. If the obtained V2X resource is a dedicated V2X resource, the terminal device may directly use the resource, and if the obtained V2X resource of the first cell is a resource pool, the terminal device may first use the special sending resource pool included in the obtained V2X resource of the first cell to send data, and send the sending resource pool included in the obtained V2X resource of the first cell (or may also be stated as using the special sending resource pool corresponding to the second identifier until obtaining the sending result of the sending resource pool corresponding to the second identifier), and then use the sending resource pool corresponding to the second identifier to send data after obtaining the sending result.

Or, if the re-obtained V2X resource of the first cell is a resource pool, the terminal device may first use a transmission resource pool included in the V2X resource before the first cell to transmit data, and perform sensing on the re-obtained transmission resource pool included in the V2X resource of the first cell, and then use the transmission resource pool to transmit data after obtaining the sensing result. In this way, the terminal device may use as little special transmission resource pool as possible to reduce collisions with other terminal devices.

In addition, if the network device adjusts the identifier of the area corresponding to the first cell to be the second identifier, for example, the identifier of the area corresponding to the original cell of a terminal device is the first identifier, and for the terminal device, if the terminal device enters the first cell before the network device adjusts, the terminal device does not need to re-request the SIB in the first cell, and can continue to use the V2X resource of the original cell of the terminal device; if the terminal device enters the first cell after the network device is adjusted, the terminal device needs to re-request the SIB in the first cell to re-acquire the V2X resource of the first cell, and if the acquired V2X resource is a resource pool, the terminal device needs to send the resource pool therein.

In order to solve the same technical problem, a fourth resource allocation method is provided in the embodiment of the present application, please refer to fig. 9, which is a flowchart of the method. In the following description, the method is applied to the network architecture shown in fig. 5 as an example. In addition, the method may be performed by two communication devices, for example, a seventh communication device and an eighth communication device. The seventh communication device may be a network device or a communication device capable of supporting the network device to implement the functions required by the method, or may be a terminal device or a communication device capable of supporting the terminal device to implement the functions required by the method, or may be other communication devices, such as a system on a chip. Similarly, the eighth communication device may be a network device or a communication device capable of supporting the network device to implement the functions required by the method, or may be a terminal device or a communication device capable of supporting the terminal device to implement the functions required by the method, and may of course be other communication devices, such as a system on a chip. The seventh communication device and the eighth communication device are not limited to be implemented, for example, the two communication devices may be implemented in the same form, for example, both implemented in the form of a device, or the two communication devices may also be implemented in different forms, for example, the seventh communication device is implemented in the form of a device, the eighth communication device is implemented in the form of a system-on-chip, and so on. The network device is, for example, a base station.

For convenience of introduction, in the following, the method is performed by the network device and the terminal device as an example, that is, the seventh communication apparatus is the network device, and the eighth communication apparatus is the terminal device as an example. Since this embodiment is applied to the network architecture shown in fig. 5 as an example, the network device described below may be the network device in the network architecture shown in fig. 5, and the terminal device described below may be the terminal device 1 or the terminal device 2 in the network architecture shown in fig. 5, and if the terminal device described below is the terminal device 1 in the network architecture shown in fig. 5, the other terminal device described below may be the terminal device 2 in the network architecture shown in fig. 5, or if the terminal device described below is the terminal device 2 in the network architecture shown in fig. 5, the other terminal device described below may be the terminal device 1 in the network architecture shown in fig. 5. In addition, for the sake of simplicity of description, the V2X terminal device is also referred to simply as a terminal device hereinafter.

S91, the network equipment generates a handover command, the handover command is used for instructing the terminal equipment to handover to the second cell, and the handover command is also used for instructing whether the V2X resource of the second cell is the same as the V2X resource of the first cell.

The first cell may be a cell under the network device, and specifically, the first cell is a cell where the network device sends a handover command, that is, a serving cell of the terminal device to be handed over.

The V2X resources may comprise a V2X resource pool for at least one terminal device application, or comprise dedicated V2X resources for a terminal device application, that is, the terminal device that received the first message. Wherein the V2X resource pool comprises at least one of the following: a transmit resource pool for providing V2X transmit resources, a receive resource pool for providing V2X receive resources, and a special transmit resource pool for providing V2X transmit resources.

The embodiment of the application can be used for a scene of switching the terminal equipment.

Wherein the handover command indicates whether the V2X resource of the second cell is the same as the V2X resource of the first cell, including but not limited to one or more of the following indication:

1. the handover command carries indication information indicating whether the V2X resource of the second cell is the same as the V2X resource of the first cell.

This manner of indication may be considered an explicit manner of indication. In this way, indication information may be directly added to the handover command, for example, the indication information may occupy 1 bit, and the handover command may explicitly indicate whether the V2X resource of the second cell is the same as the V2X resource of the first cell through the indication information. It is also possible to indicate whether the receiving resource pool or the transmitting resource pool or the special resource pool or the dedicated resource in the V2X resource of the second cell corresponds to the same or different receiving resource pool or the transmitting resource pool or the special resource pool or the dedicated resource in the V2X resource of the first cell, respectively, using several bits. This way of indication is relatively unambiguous.

2. The handover command does not carry a special transmission resource pool for providing V2X transmission resources, indicating that the V2X resources of the second cell are the same as the V2X resources of the first cell, or the handover command carries a special transmission resource pool for providing V2X transmission resources, indicating that the V2X resources of the second cell are different from the V2X resources of the first cell.

This manner of indication may be considered as an implicit manner of indication. It can be understood that if the handover command does not carry the special transmission resource pool of the second cell, it is equivalent to an implicit indication that the V2X resource (transmission resource pool or dedicated transmission resource) of the second cell is the same as the V2X resource (transmission resource pool or dedicated transmission resource) of the first cell, and the terminal device does not need to obtain the V2X resource (transmission resource pool or dedicated transmission resource) of the second cell any more; on the other hand, if the handover command carries the special transmission resource pool of the second cell, it is equivalent to an implicit indication that the V2X resource (transmission resource pool or dedicated transmission resource) of the second cell is different from the V2X resource (transmission resource pool or dedicated transmission resource) of the first cell, the terminal device needs to use the special transmission resource pool of the second cell for transmission during handover, and the terminal device needs to obtain the V2X resource of the second cell again.

3. The handover command does not carry a transmission resource pool or dedicated transmission resources for providing the V2X transmission resources, indicates that the V2X resources (transmission resource pool or dedicated transmission resources) of the second cell are the same as the V2X resources (transmission resource pool or dedicated transmission resources) of the first cell, or the handover command carries a transmission resource pool or dedicated transmission resources for providing the V2X transmission resources, indicates that the V2X resources (transmission resource pool or dedicated transmission resources) of the second cell are different from the V2X resources (transmission resource pool or dedicated transmission resources) of the first cell.

This way of indication can also be considered as an implicit way of indication. It can be understood that if the handover command does not carry the transmission resource pool or dedicated transmission resource of the second cell, it is equivalent to an implicit indication that the V2X resource (transmission resource pool or dedicated transmission resource) of the second cell is the same as the V2X resource (transmission resource pool or dedicated transmission resource) of the first cell, and the terminal device does not need to obtain the V2X resource (transmission resource pool or dedicated transmission resource) of the second cell any more; on the other hand, if the handover command carries the transmission resource pool or dedicated transmission resource of the second cell, it is equivalent to an implicit indication that the V2X resource (transmission resource pool or dedicated transmission resource) of the second cell is different from the V2X resource (transmission resource pool or dedicated transmission resource) of the first cell, and the terminal device needs to obtain the V2X resource (transmission resource pool or dedicated transmission resource) of the second cell again.

Using the implicit indication method, no additional information needs to be added to the handover command, and it is also possible to reduce the information included in the handover command (for example, the handover command may not include the special transmission resource pool and/or the transmission resource pool of the second cell and/or the dedicated transmission resource), which helps to save signaling overhead, and also does not need to change the original message structure of the handover command.

Of course, the handover command indicates whether the V2X resource of the second cell is the same as the V2X resource of the first cell, and other indication manners are possible besides the above three indication manners, which are not limited specifically.

S92, the network device sends the switching command, and the terminal device receives the switching command from the network device.

S93, the terminal equipment determines to switch to the second cell according to the switching command, and determines whether the V2X resource of the second cell is the same as the V2X resource of the first cell according to the switching command.

Wherein, if the handover command carries indication information indicating whether the V2X resource of the second cell is the same as the V2X resource of the first cell, the terminal device may determine whether the V2X resource of the second cell is the same as the V2X resource of the first cell according to the indication information.

Alternatively, if the handover command does not carry the special transmission resource pool of the second cell, it indicates that the V2X resource of the second cell is the same as the V2X resource of the first cell, or the handover command carries the special transmission resource pool of the second cell, indicating that the V2X resource of the second cell is different from the V2X resource of the first cell. Then, the terminal device may determine whether the V2X resource of the second cell is the same as the V2X resource of the first cell according to whether the handover command carries the special transmission resource pool of the second cell. For example, the handover command does not carry the special transmission resource pool of the second cell, and the terminal device determines that the V2X resource of the second cell is the same as the V2X resource of the first cell, or the handover command carries the special transmission resource pool of the second cell, and the terminal device determines that the V2X resource of the second cell is different from the V2X resource of the first cell.

Or, if the handover command does not carry the transmission resource pool or dedicated transmission resource of the second cell, indicating that the V2X resource of the second cell is the same as the V2X resource of the first cell, or, the handover command carries the transmission resource pool or dedicated transmission resource of the second cell, indicating that the V2X resource of the second cell is different from the V2X resource of the first cell. Then, the terminal device may determine whether the V2X resource of the second cell is the same as the V2X resource of the first cell according to whether the handover command carries the transmission resource pool or the dedicated transmission resource of the second cell. For example, the handover command does not carry the transmission resource pool or dedicated transmission resource of the second cell, and the terminal device determines that the V2X resource of the second cell is the same as the V2X resource of the first cell, or the handover command carries the transmission resource pool or dedicated transmission resource of the second cell, and the terminal device determines that the V2X resource of the second cell is different from the V2X resource of the first cell.

S94, on the condition that the V2X resource of the second cell is the same as the V2X resource of the first cell, the terminal equipment continues to use the V2X resource of the first cell after switching to the second cell.

If the V2X resources (tx/rx/special tx) of the second cell are the same as the V2X resources (tx/rx/special tx) of the first cell, the terminal device can continue to use the V2X resources (tx/rx/special tx) of the first cell after switching to the second cell without acquiring the V2X resources (tx/rx/special tx) of the second cell, which reduces the process for acquiring the V2X resources by the terminal device. For example, the V2X resource of the first cell is a V2X resource pool, the terminal device does not need to sense a transmission resource pool in the V2X resource pool, so as to reduce power consumption of the terminal device, and the terminal device does not need to use a special transmission resource pool in the V2X resource pool, but can directly use the transmission resource pool, so as to reduce possible conflicts between the terminal device and other terminal devices in resource selection.

Alternatively, if the V2X resource of the second cell is different from the V2X resource of the first cell, the terminal device may use the V2X resource of the second cell after handing over to the second cell. For example, the terminal device may obtain the V2X resource of the second cell through a system message sent by the second cell, or may obtain the V2X resource of the second cell through a handover command, or may also obtain the V2X resource configured by the second cell after accessing the second cell. If the obtained V2X resource of the second cell is a dedicated V2X resource, the terminal device may use the resource directly, or if the obtained V2X resource of the second cell is a resource pool, in terms of transmission, the terminal device may first use a special transmission resource pool of the second cell to transmit data, and perform sensing on the transmission resource pool of the second cell, and then use the transmission resource pool of the second cell after obtaining the sensing result, in terms of reception, the terminal device may receive data using a reception resource pool of the second cell.

In order to solve the same technical problem, an embodiment of the present application provides a fifth resource allocation method, please refer to fig. 10, which is a flowchart of the method. In the following description, the method is applied to the network architecture shown in fig. 5 as an example. In addition, the method may be performed by two communication devices, for example, a ninth communication device and a tenth communication device. The ninth communication device may be a network device or a communication device capable of supporting the network device to implement the functions required by the method, or may be a terminal device or a communication device capable of supporting the terminal device to implement the functions required by the method, or may be other communication devices, such as a system on a chip. Similarly, the tenth communication apparatus may be a network device or a communication apparatus capable of supporting a network device to implement the functions required by the method, or may be a terminal device or a communication apparatus capable of supporting a terminal device to implement the functions required by the method, and may of course be other communication apparatuses, such as a system on chip. The ninth communication apparatus and the tenth communication apparatus are not limited to be implemented, for example, the two communication apparatuses may be implemented in the same form, for example, both are implemented in the form of a device, or the two communication apparatuses may also be implemented in different forms, for example, the ninth communication apparatus is implemented in the form of a device, the tenth communication apparatus is implemented in the form of a system-on-chip, and so on. The network device is, for example, a base station.

For convenience of introduction, in the following, the method is performed by a network device and a terminal device as an example, that is, the ninth communication apparatus is a network device and the tenth communication apparatus is a terminal device as an example. Since this embodiment is applied to the network architecture shown in fig. 5 as an example, the network device described below may be the network device in the network architecture shown in fig. 5, and the terminal device described below may be the terminal device 1 or the terminal device 2 in the network architecture shown in fig. 5, and if the terminal device described below is the terminal device 1 in the network architecture shown in fig. 5, the other terminal device described below may be the terminal device 2 in the network architecture shown in fig. 5, or if the terminal device described below is the terminal device 2 in the network architecture shown in fig. 5, the other terminal device described below may be the terminal device 1 in the network architecture shown in fig. 5. In addition, for the sake of simplicity of description, the V2X terminal device is also referred to simply as a terminal device hereinafter.

S101, the network equipment generates a first message, and the first message carries the V2X resource of the second cell.

The first message may be a system message, for example, the second cell is a candidate cell for the terminal device to perform cell reselection, and the first message may be a system message sent by the network device in the second cell; alternatively, the first message may also be a handover command, for example, the second cell is a target cell when the terminal device performs cell handover, and the first message may be a handover command sent by the network device in the first cell. It can be seen that the network device may be a network device corresponding to the first cell or a network device corresponding to the second cell. The network device corresponding to the first cell (i.e., the network device that sends the message in the first cell) and the network device corresponding to the second cell (i.e., the network device that sends the message in the second cell) may be the same network device or different network devices. The first cell may be a source cell of the terminal device before cell handover.

Wherein the V2X resource of the second cell may comprise a V2X resource pool for at least one terminal device to apply, or comprise a dedicated V2X resource for a terminal device, that is, the terminal device receiving the first message. Wherein the V2X resource pool comprises at least one of the following: a transmit resource pool for providing V2X transmit resources, a receive resource pool for providing V2X receive resources, and a special transmit resource pool for providing V2X transmit resources. The dedicated V2X resource is a V2X resource dedicated for use by one terminal device that does not have to compete with other terminal devices, the dedicated V2X resource may include a transmission resource for which the terminal device does not have to transmit but may be used directly and/or a reception resource.

S102, the network equipment sends the first message, and the terminal equipment receives the first message from the network equipment.

If the first message is a system message, the network device may be a broadcast first message, and if the first message is a handover command, the network device may be a unicast first message.

S103, the terminal equipment determines whether the V2X resource of the second cell is the same as the V2X resource of the first cell.

For example, the terminal device determines whether the V2X resource of the second cell is the same as the V2X resource of the terminal device first cell, including but not limited to one of the following two ways:

1. the terminal device determines whether the configuration information of the V2X resource of the second cell is the same as the configuration information of the V2X resource of the first cell, wherein if the configuration information of the V2X resource of the second cell is the same as the configuration information of the V2X resource of the first cell, the terminal device determines that the V2X resource of the second cell is the same as the V2X resource of the first cell of the terminal device, otherwise, the terminal device determines that the V2X resource of the second cell is different from the V2X resource of the first cell of the terminal device.

In this manner, the terminal device can determine whether the two V2X resources are the same by comparing the configuration information of the two V2X resources. For example, the terminal device compares the transmission resource pool configuration of the first cell with the transmission resource pool configuration of the second cell to determine whether the transmission resources of V2X of the two cells are the same.

2. And determining whether the position of the V2X resource of the first cell is the same as the position of the V2X resource of the current cell, wherein if the position of the V2X resource of the first cell is the same as the position of the V2X resource of the current cell, the terminal device determines that the V2X resource of the first cell is the same as the V2X resource of the current cell of the terminal device, otherwise, the terminal device determines that the V2X resource of the first cell is different from the V2X resource of the current cell of the terminal device.

In this manner, the terminal device may determine whether the two V2X resources are the same by comparing the locations of the two V2X resources. For example, the terminal device determines whether the transmission resources of V2X of the two cells are the same by comparing the transmission resource pool location of the first cell with the transmission resource pool location of the second cell.

Comparing the configuration information of the V2X resource and the location of the V2X resource is simpler to implement than comparing the V2X resource directly. Of course, the way for the terminal device to determine whether the V2X resource of the second cell is the same as the V2X resource of the terminal device first cell is not limited to the above two.

S104, the V2X resource of the second cell is the same as the V2X resource of the first cell, and the terminal equipment determines to continue to use the V2X resource of the first cell after switching to the second cell.

If the V2X resources of the second cell are the same as the V2X resources of the first cell, the terminal device may continue to use the V2X resources of the first cell without obtaining the V2X resources of the second cell after reselecting or handing over to the second cell. For example, the V2X resource of the first cell is a V2X resource pool, the terminal device does not need to sense a transmission resource pool in the V2X resource pool, so as to reduce power consumption of the terminal device, and the terminal device does not need to use a special transmission resource pool in the V2X resource pool, but can directly use the transmission resource pool, so as to reduce possible conflicts between the terminal device and other terminal devices in resource selection.

Alternatively, if the V2X resource of the second cell is different from the V2X resource of the first cell, the terminal device may use the V2X resource of the second cell after cell reselection or cell handover to the second cell. For example, the terminal device may obtain the V2X resource of the second cell through a system message sent by the second cell, or may obtain the V2X resource of the second cell through a handover command sent by the first cell, or may also obtain the V2X resource configured by the second cell after accessing the second cell. If the obtained V2X resource of the second cell is a dedicated V2X resource, the terminal device may use the resource directly, or if the obtained V2X resource of the second cell is a resource pool, in terms of transmission, the terminal device may first use a special transmission resource pool of the second cell to transmit data, and perform sensing on the transmission resource pool of the second cell, and then use the transmission resource pool of the second cell after obtaining the sensing result, in terms of reception, the terminal device uses a reception resource pool of the second cell.

In order to solve the same technical problem, an embodiment of the present application provides a sixth resource allocation method, please refer to fig. 11, which is a flowchart of the method. In the following description, the method is applied to the network architecture shown in fig. 5 as an example. In addition, the method may be performed by two communication devices, for example, an eleventh communication device and a twelfth communication device. The eleventh communication device may be a network device or a communication device capable of supporting the network device to implement the functions required by the method, or may be a terminal device or a communication device capable of supporting the terminal device to implement the functions required by the method, and may also be other communication devices, such as a system on a chip. Similarly, the twelfth communication device may be a network device or a communication device capable of supporting the network device to implement the functions required by the method, or may be a terminal device or a communication device capable of supporting the terminal device to implement the functions required by the method, and may of course be other communication devices, such as a system on a chip. The implementation manners of the eleventh communication apparatus and the twelfth communication apparatus are not limited, for example, the two communication apparatuses may be implemented in the same form, for example, both are implemented in the form of a device, or the two communication apparatuses may also be implemented in different forms, for example, the eleventh communication apparatus is implemented in the form of a device, the twelfth communication apparatus is implemented in the form of a system-on-chip, and so on. The network device is, for example, a base station.

For convenience of introduction, in the following, the method is performed by a network device and a terminal device as an example, that is, the eleventh communication apparatus is a network device and the twelfth communication apparatus is a terminal device as an example. Since this embodiment is applied to the network architecture shown in fig. 5 as an example, the network device described below may be the network device in the network architecture shown in fig. 5, and the terminal device described below may be the terminal device 1 or the terminal device 2 in the network architecture shown in fig. 5, and if the terminal device described below is the terminal device 1 in the network architecture shown in fig. 5, the other terminal device described below may be the terminal device 2 in the network architecture shown in fig. 5, or if the terminal device described below is the terminal device 2 in the network architecture shown in fig. 5, the other terminal device described below may be the terminal device 1 in the network architecture shown in fig. 5. In addition, for the sake of simplicity of description, the V2X terminal device is also referred to simply as a terminal device hereinafter.

S111, the network equipment generates a first message, wherein the first message comprises indication information, the indication information is used for indicating that the first information corresponds to V2X resources, and the first information is cell information and/or frequency information.

The first message may be a system message or may be dedicated signaling, which is not limited in particular.

The V2X resource corresponding to the first information refers to a V2X resource to which the first information can be applied, that is, the V2X resource can be used when the terminal device operates in the first information.

The V2X resource corresponding to the first information may comprise a V2X resource pool for at least one terminal device application, or comprise a dedicated V2X resource for a terminal device application, which is the terminal device receiving the first message. Wherein the V2X resource pool comprises at least one of the following: a transmit resource pool for providing V2X transmit resources, a receive resource pool for providing V2X receive resources, and a special transmit resource pool for providing V2X transmit resources. The dedicated V2X resource is a V2X resource dedicated for use by one terminal device that does not have to compete with other terminal devices, the dedicated V2X resource may include a transmission resource and/or a reception resource, and for the transmission resource included in the dedicated V2X resource, the terminal device does not have to perform sensing but may directly use it.

For example, the network device may send a first message in a first cell, such as a serving cell of the terminal device. Then, if the first information is cell information, the cell information may correspond to one or more cells, and the first cell is not a cell to which the cell information corresponds; or, if the first information is frequency information, the frequency of the first cell is different from the frequency corresponding to the first information.

For example, if the first information is cell information, the network device may indicate, through the indication information, V2X resources of cells other than the first cell, where a frequency of a cell corresponding to the cell information as the first information may be the same as or different from a frequency of the first cell. This may also be understood as the case where the first message indicates V2X resources and a cell list is set for the V2X resources, the cell list including the identity of one or more cells.

Or for example, the first information is frequency information, and the network device may indicate, through the indication information, V2X resources corresponding to other frequencies different from the frequency of the first cell. In this case, the first message may further include an identifier of one or more cells corresponding to the first information, which is used to indicate that the V2X resource may specifically apply to the cell corresponding to the identifier of the one or more cells, or the first message may not include an identifier of any cell corresponding to the first information, which is used to indicate that the V2X resource may specifically apply to all cells under the first information. For example, the first information is frequency 1 information, the first message indicates that frequency 1 corresponds to V2X resource 1, and the first message also indicates cell 1 and cell 2 at frequency 1, which may indicate that V2X resource 1 may be applicable to cell 1 and cell 2 at frequency 1, while V2X resource 1 may not necessarily be applicable to other cells than cell 1 and cell 2 at frequency 1. Or for example, the first information is information of frequency 1, the first message indicates that frequency 1 corresponds to V2X resource 1, and the first message does not indicate any cell in frequency 1, which may indicate that V2X resource 1 may be applicable to all cells in frequency 1.

S112, the network device sends or broadcasts the first message in the first cell, and the terminal device receives the first message from the network device in the first cell.

After the network device generates the first message, if the first message is dedicated signaling, the network device sends the first message in the first cell, where "send" may be understood as unicast, or if the first message is a system message, the network device broadcasts the first message in the first cell, and the terminal device may receive the first message from the network device.

S113, the terminal device determines, according to indication information included in the first message, a V2X resource corresponding to first information, where the first information is cell information or frequency information, the first cell does not belong to a cell corresponding to the cell information, and the frequency information and the frequency of the first cell are not the same frequency.

If the first information is cell information, the terminal equipment determines the V2X resource corresponding to the cell information according to the indication information, and if the first information is frequency information, the terminal equipment determines the V2X resource corresponding to the frequency information according to the indication information.

For example, the first information is cell information, and the frequency of the cell corresponding to the cell information as the first information may be the same as or different from the frequency of the first cell. For example, the indication information indicates the V2X resource and the cell information, the indication information further includes a cell list corresponding to the V2X resource, the cell list includes cell information as the first information, the cell information may include identities of one or more cells, and the terminal device determines that the cell corresponding to the identity of the cell included in the cell list is applicable to the V2X resource.

Or, for example, the first information is frequency information. The indication information indicates the V2X resource and the frequency information, and may additionally indicate an identifier of one or more cells corresponding to the first information, and the terminal device may determine that the V2X resource may be specifically applicable to the cell corresponding to the identifier of the one or more cells, or, if the indication information does not include the identifier of any cell corresponding to the first information, the terminal device may determine that the V2X resource may be specifically applicable to all cells under the first information. For example, if the first information is information of frequency 1, the indication information indicates that frequency 1 corresponds to V2X resource 1, and the indication information also indicates cell 1 and cell 2 on frequency 1, the terminal device may determine that V2X resource 1 may be applicable to cell 1 and cell 2 on frequency 1, and V2X resource 1 may not be applicable to other cells than cell 1 and cell 2 on frequency 1. Or for example, the first information is information of frequency 1, the indication information indicates that frequency 1 corresponds to V2X resource 1, and the indication information does not indicate any cell in frequency 1, the terminal device may determine that V2X resource 1 may be applicable to all cells in frequency 1.

S114, the terminal equipment uses the V2X resource in the first cell.

Although the V2X resource is not configured for the first cell, the terminal device may use the V2X resource even under the first cell. For example, if the first information is cell information and the terminal device is able to search for one or more cells in the cell corresponding to the cell information, the terminal device may use the V2X resource in the first cell; or, if the first information is frequency information and the indication information also indicates cell information at a frequency corresponding to the frequency information, the terminal device may use the V2X resource in the first cell if the terminal device can search for one or more cells at the frequency corresponding to the frequency information indicated by the indication information; alternatively, if the first information is frequency information and the indication information does not indicate cell information at a frequency corresponding to the frequency information, the terminal device may use the V2X resource at the first cell if the terminal device can search for any one or more cells at the frequency corresponding to the frequency information.

For example, if the V2X resource is specifically a V2X resource pool, if the terminal device needs to transmit data, the terminal device may first use a special transmission resource pool in the V2X resource pool, and perform sensing on the transmission resource pool in the V2X resource pool, and then use the transmission resource pool in the V2X resource pool until a sensing result of the transmission resource pool in the V2X resource pool is obtained.

S115, when performing cell reselection or cell handover, the terminal device enters a second cell from the first cell, and continues to use the V2X resource in the second cell, where the first information is cell information, and the second cell belongs to a cell corresponding to the cell information, or the first information is frequency information, and the second cell is a cell in a frequency corresponding to the frequency information.

When the terminal device performs cell reselection or cell handover, the terminal device may leave from the first cell and enter into a second cell, for example, the second cell is a target cell of the terminal device.

If the first information is cell information, the terminal device may determine whether the second cell belongs to a cell corresponding to the cell information, and if the second cell is one of the cells corresponding to the cell information, the terminal device may determine that the second cell is suitable for the V2X resource, that is, the V2X resource may be continuously used in the second cell. Otherwise, if the second cell does not belong to the cell corresponding to the cell information, the terminal device cannot determine whether the second cell is suitable for the V2X resource, that is, cannot determine whether the V2X resource can be continuously used in the second cell. The second cell may be one of the cells searched by the terminal device in S114, or may not belong to the cell searched by the terminal device in S114.

Alternatively, if the first information is frequency information, and if the first message does not include cell information corresponding to the first information, the terminal device may determine that the V2X resource is applicable to the second cell, that is, the V2X resource may be continuously used in the second cell, as long as it determines that the frequency of the second cell belongs to the frequency corresponding to the frequency information. Otherwise, if the frequency of the second cell does not belong to the frequency corresponding to the frequency information, the terminal device cannot determine whether the second cell is suitable for the V2X resource, that is, cannot determine whether the V2X resource can be continuously used in the second cell. The second cell may be one of the cells under the frequency corresponding to the frequency information searched in S114 by the terminal device, or may not belong to the cell under the frequency corresponding to the frequency information searched in S114 by the terminal device.

Or, if the first information is frequency information, and if the first message includes cell information corresponding to the first information, the terminal device needs to determine whether the frequency of the second cell belongs to a frequency corresponding to the frequency information, and if the frequency of the second cell belongs to a frequency corresponding to the frequency information, the terminal device also needs to determine whether the second cell belongs to a cell at the frequency corresponding to the frequency information indicated by the indication information, or, if the identity of the cell is unique for the cell, the terminal device may also directly determine whether the second cell belongs to a cell at the frequency corresponding to the frequency information indicated by the indication information. If the second cell belongs to the cell at the frequency corresponding to the frequency information indicated by the indication information, the terminal device may determine that the V2X resource is applicable to the second cell, that is, the V2X resource may be continuously used in the second cell; otherwise, if the second cell does not belong to the cell at the frequency corresponding to the frequency information indicated by the indication information, the terminal device cannot determine whether the V2X resource is applicable to the second cell, that is, whether the V2X resource can be continuously used in the second cell.

If the V2X resource can continue to be used in the second cell, the terminal device second cell can continue to use the V2X resource of the first cell without obtaining the V2X resource of the second cell. For example, the V2X resource of the first cell is a V2X resource pool, the terminal device does not need to sense a transmission resource pool in the V2X resource pool, so as to reduce power consumption of the terminal device, and the terminal device does not need to use a special transmission resource pool in the V2X resource pool, but can directly use the transmission resource pool, so as to reduce possible conflicts between the terminal device and other terminal devices in resource selection.

Alternatively, if it cannot be determined whether the V2X resource can be continuously used under the second cell, the terminal device may use the V2X resource of the second cell in the second cell. For example, the terminal device may obtain the V2X resource of the second cell through a system message sent by the second cell, or may obtain the V2X resource of the second cell through a handover command sent by the first cell, or may also obtain the V2X resource configured by the second cell after accessing the second cell. If the obtained V2X resource of the second cell is a dedicated V2X resource, the terminal device may use the resource directly, or if the obtained V2X resource of the second cell is a resource pool, the terminal device may first use a special transmission resource pool of the second cell to transmit data, perform sensing on the transmission resource pool of the second cell, and use the transmission resource pool of the second cell after obtaining the sensing result.
