In order to more clearly describe the technical solution according to the embodiment of the present disclosure, the following will be described in detail in conjunction with the drawings and specific embodiments.

In order to more clearly describe the technical solution according to the embodiment of the present disclosure, the following will be described in detail in conjunction with the drawings and specific embodiments.

Referring to FIG. 1, FIG. 1 is a diagram of a network structure to be applied to an embodiment of the present disclosure. 1, the network includes a plurality of terminals 11 and network-side devices 12, among which the terminal 11 may be a user equipment (UE) or other terminal equipment. Bars such as: Cell Phones, Tablet Personal Computers, Laptop Computers, Personal Digital Assistants (PDAs), Mobile Internet Devices (MIDs), in-vehicle devices or wearable devices It may be a terminal-side device such as (Wearable Device), and it should be noted that the specific type of the terminal is not limited in the embodiment of the present disclosure. Direct communication (or referred to as direct communication) may be performed between the terminals 11 through a direct communication interface, and among them, the link of direct communication may be referred to as a Sidelink (or translated as a direct communication link or a sidelink), Sidelink The interface corresponding to the is referred to as a direct communication interface. All terminals of direct communication may be on-network, or all may be off-network, and some devices may be on-network and some devices may be off-network. On-network means that the device participating in direct communication is located within the 3GPP base station communication carrier coverage range, and off-network means that the device participating in direct communication is not located within the 3GPP base station communication carrier coverage range. The network device 12 may be a base station, such as a macro station, LTE eNB, 5G NR NB, or the like; The network device may also be a small station such as a low power node (LPN), pico, femto, or the network device may be an access point (AP); The base station may be a network node jointly configured with a central unit (CU) and a plurality of distributed units (DU) managed and controlled by the central unit. It should be noted that, in the embodiments of the present disclosure, specific types of network-side devices are not limited.

Referring to FIG. 2 , FIG. 2 is a flowchart of a cell selection method provided in an embodiment of the present disclosure, and as shown in FIG. 2 , the method includes:

Step 201: The terminal receives a broadcast message transmitted by a network device, wherein the broadcast message determines whether the network device supports inter-radio access technology (RAT) deployment, the inter-RAT supported by the network device is configured Receiving, for indicating at least one of a mode and a resource location arranged by an inter RAT supported by the network device; and

Step 202: The terminal performs cell selection according to the broadcast message, wherein the cell selection is initial cell selection or cell reselection; includes

Among them, step 201 may be a step of receiving a broadcast message transmitted by one or a plurality of network devices, and the broadcast message of each network device determines whether each network device supports inter RAT arrangement, and the supported inter RAT arrangement This is to indicate at least one of a resource location arranged by one mode and a supported inter RAT.

What needs to be explained is whether or not the network device supports inter-RAT deployment can be understood as whether a cell corresponding to the network device supports inter-RAT deployment, and the mode arranged by the inter-RAT supported by the network device; It can be understood as a mode arranged by the inter RAT supported by the cell corresponding to the network device, and the resource location arranged by the inter RAT supported by the network device is the resource position arranged by the inter RAT supported by the cell corresponding to the network device. can be understood as

And, when the broadcast message indicates the mode arranged by the inter RAT supported by the network device, it may default to that the network device supports the inter RAT arrangement, and in the broadcast message, the inter RAT supported by the network device When the resource location is indicated, it may be defaulted that the network device supports inter-RAT arrangement.

In a selectable implementation manner, the broadcast message includes at least one or more of the following fields,

Option 1: an indication field indicating whether to support inter-RAT deployment;

For example, if the corresponding field is N bits, N is a positive integer greater than or equal to 1, specifically, it may be 1 bit, and a value of 0 indicates not supported, and a value of 1 indicates that it is supported. indicates.

Option 2: A field indicating the resource distribution mode arranged by the inter RAT;

For example, the corresponding field is M bits, M is a positive integer greater than or equal to 1, specifically, it may be 2 bits, and a value of 11 indicates that all resource distribution modes are supported, and the value is When 01 or 10, it indicates that only one resource distribution mode is supported. For example, 01 indicates that only the resource distribution mode selected by the terminal is supported, and 10 indicates that only the resource distribution mode scheduled by the network is supported. It indicates support, and when the value is 00, it indicates that the inter RAT does not support any resource distribution mode, that is, does not support the inter RAT arrangement.

Option 3: A field indicating a resource location arranged by the inter RAT;

The field indicates the resource location of another RAT arranged by the inter RAT, for example, the base station of the NR indicates the location of the LTE V2X resource (eg, arrangement by the resource pool, etc.), if the field exists If so, it indicates that the inter-RAT arrangement is supported, and the specific supported distribution mode may specifically indicate or default that only the resource distribution mode selected by the terminal itself is supported, or the resource pool location related to the field has already been assigned. Therefore, if the field does not exist, it indicates that inter RAT arrangement is not supported, that is, it implicitly indicates that inter RAT arrangement is not supported.

It should be explained that the step of performing cell selection according to the broadcast message may be a step of performing cell selection by combining other information of the network device according to the broadcast message, for example, combining traffic supported by the network device. Alternatively, cell selection may be performed by combining information such as whether the network device supports inter-carrier deployment, among which such information is transmitted by the network device to the terminal or obtained by measuring the terminal , or may be pre-arranged, etc., but is not limited thereto. Of course, in some implementations, cell selection may be performed only according to the above-described broadcast message, but the present invention is not limited thereto.

In an embodiment of the present disclosure, it is possible to implement that the network device transmits broadcast information through the above-described steps, and the broadcast information includes the RAT arrangement of the network device, the mode arranged by the inter-RAT supported by the network device, and the It indicates at least one of resource locations arranged by the inter RAT supported by the network device. The terminal device receives the broadcast information transmitted by the network device, and selects a cell according to the broadcast information. In this way, it is possible to implement that the UE selects a cell according to the arrangement of the RAT, and thus, it is possible to select a cell that is more suitable for the UE demand, thereby improving the communication performance of the UE. In addition, in the NR system, the network device can support the inter-RAT arrangement in addition to supporting the inter-carrier arrangement, and the traffic supported by the terminal is also richer, so the cell provided in the embodiment of the present disclosure The selection method can solve the problem of how the terminal performs cell selection and/or reselection, and enables the terminal device to select a suitable cell, thereby improving the communication performance of the terminal.

As a selectable implementation method, the step of the terminal performing cell selection according to the broadcast message comprises:

performing, by the terminal, cell selection according to the cell priority level order according to the broadcast message; includes

Among them, the above-described cell priority level order may be arranged in advance, stipulated in a protocol, or arranged by the network side.

According to the broadcast message, the step of performing cell selection according to the cell priority level order includes: the terminal determines the cell type according to the above-mentioned broadcast message, and selects each type of cell according to the above-mentioned cell priority level order. It may be a step of determining the priority level.

Optionally, if the cell priority level sequence includes a priority level in which a plurality of cells exist, the terminal selects a cell having the strongest signal strength among the plurality of cells or selects a cell at random . That is, if a plurality of cells are included in the highest priority level in a cell selectable by the terminal, the terminal selects a cell having the strongest signal strength from among the plurality of cells or randomly selects one cell. Of course, in the embodiment of the present disclosure, without limitation, for example, the terminal may select by itself, and the terminal may select one according to a rule set by itself, that is, select a cell belonging to the terminal implementation.

Optionally, according to the cell priority level order, if there is no selectable cell, the terminal proceeds with traffic using a pre-arranged resource.

For example, if there is no selectable cell, the terminal recognizes that the terminal is in an off-network state, proceeds V2X traffic using pre-arranged resources, and specifically, may be to proceed with the transmission of the traffic, and the terminal is off Improves communication performance in network conditions.

It should be explained that a plurality of cells may be included in the above-described cell priority level order, but in an actual application, the number of cells that the UE can select may be less than the number of cells in the cell priority order, so the UE selects In the process, a cell having the highest priority level may be selected from among the cells that the UE can select.

In the above implementation method, by performing cell selection according to the above-described cell priority level order, a cell more suitable for the terminal demand may be selected, thereby improving the communication performance of the terminal.

What should be described is, in order to more clearly explain the technical solution according to the present disclosure, taking a Long Term Evolution (LTE) system and a New Radio (NR) system as examples, and dividing the cell type as follows can do,

a) directly providing LTE V2X traffic, not providing inter-carrier deployment, and not providing inter-RAT deployment;

b) deploying LTE V2X traffic by providing an inter-carrier, but not providing an inter-RAT deployment;

c) directly providing LTE V2X traffic, not providing inter-carrier deployment, but providing inter RAT to deploy NR mode mode1 or mode2;

d) providing LTE V2X traffic directly, and does not provide inter-carrier deployment, but provides inter RAT to deploy NR mode1 and mode2;

e) deploying LTE V2X traffic by providing inter RAT, and deploying LTE mode3 or mode4 by providing inter RAT;

f) deploying LTE V2X traffic by providing inter RAT, and deploying LTE mode3 and mode4 by providing inter RAT;

g) deploying LTE V2X traffic by providing an inter-carrier, and also providing an inter RAT to deploy NR mode1 or mode2;

h) deploying LTE V2X traffic by providing an inter-carrier, and deploying NR mode1 and mode2 by providing an inter RAT;

i) directly providing NR V2X traffic, not providing inter-carrier arrangement, and also not providing inter-RAT arrangement;

j) to provide an inter-carrier to deploy NR V2X traffic, but not to provide an inter-RAT deployment;

k) directly providing NR V2X traffic, not providing inter-carrier deployment, but providing inter RAT to deploy LTE mode3 or mode4;

i) directly providing NR V2X traffic, not providing inter-carrier deployment, but providing inter RAT to deploy LTE mode3 and mode4;

m) to provide inter RAT to deploy NR V2X traffic, and also to provide inter RAT to deploy NR mode1 or mode2;

n) to provide inter RAT to deploy NR V2X traffic, and also to provide inter RAT to deploy NR mode1 and mode2;

o) deploying NR V2X traffic by providing an inter-carrier, and also providing an inter RAT to deploy LTE mode3 or mode4; and

p) to provide inter-carrier to deploy NR V2X traffic, and also to provide inter RAT to deploy LTE mode3 and mode4.

Among them, the above-described NR mode1 may be a resource distribution mode scheduled by the network in the direct communication of the NR system, and the NR mode2 may be a resource distribution mode selected by the terminal itself in the direct communication of the NR system; LTE mode3 may be a resource distribution mode scheduled by the network device in the LTE system, that is, the network provides resources for the terminal according to the sidelink buffer area status reporting (BSR) reported by the terminal. It is a resource distribution mode for distributing; LTE mode4 may be a resource distribution mode selected by the terminal itself in the LTE system, that is, the terminal itself selects one resource from among the transmission resources that are pre-arranged or broadcast by the network to transmit the sidelink.

It should be explained that the above-described plurality of cells is only an example, and in an actual application, not all types of cells described above are supported in a communication system, and since it is relatively difficult to support dynamic deployment by inter RAT, For example, some types of cells such as cell type d or h may not be supported.

Optionally, the cell priority level order includes a first cell priority level order or a second cell priority level order.

Among them, the above-described first cell priority level order or second cell priority level order may be selected by the UE itself, or may be arranged by the network side, or may not be arranged.

Further, if the terminal only supports traffic of the first system, the cell priority level order is the first cell priority level order; or,

if the current traffic of the terminal is traffic of the first system, the cell priority level order is the first cell priority level order; or,

if the terminal supports the traffic of the first system and the traffic of the second system, the cell priority level order is the second cell priority level order; or,

If the current traffic of the terminal includes traffic of the first system and the second system, the cell priority level order is the second cell priority level order.

In one scheme, the first system is a Long Term Evolution (LTE) system, and the second system is a New Radio (NR) system. In another scheme, the first system described above is an NR system, and the second system is an LTE system.

It should be explained that the above-described first cell priority level order when the above-described first system is an LTE system may be different from the priority level order of the above-mentioned first system when the above-mentioned first system is an NR system. can

In addition, the above-described traffic is vehicle-to-everything (V2X) traffic, for example, the traffic of the first system may be referred to as LTE V2X traffic or NR V2X traffic, or the traffic of the second system It may be referred to as LTE V2X traffic or NR V2X traffic. It should be explained that the above-described traffic may also be traffic using other direct communication, and the present disclosure is not limited thereto.

the first cell is a cell providing traffic of the first system;

the second cell is a cell that provides inter-carrier to deploy traffic of the first system;

The third cell is a cell that provides traffic of the second system, provides inter RAT configuration, and provides inter RAT to deploy a plurality of resource distribution modes of the first system, or a cell is a cell that provides inter RAT to deploy traffic of the first system, and provides an inter RAT to deploy a plurality of resource distribution modes of the first system;

The fourth cell is a cell that provides traffic of the second system, provides inter RAT configuration, and provides only inter RAT to deploy one resource distribution mode of the first system, or 4 cell is a cell that provides inter RAT to deploy traffic of the first system, and also provides only inter RAT to deploy one resource distribution mode of the first system;

That is, the carrier of the first cell may provide the V2X traffic of the first system.

The cell in which the traffic of the first system is provided by providing the above-described inter-carrier may be a cell in which the corresponding cell cannot directly provide the traffic of the first system, and may provide V2X traffic.

For example, the corresponding field is M bits, M is a positive integer greater than or equal to 1, specifically, it may be 2 bits, and a value of 11 indicates that all resource distribution modes are supported, and the value is When 01 or 10, it indicates that only one resource distribution mode is supported. For example, 01 indicates that only the resource distribution mode selected by the terminal is supported, and 10 indicates that only the resource distribution mode scheduled by the network is supported. It indicates support, and when the value is 00, it indicates that the inter RAT does not support any resource distribution mode, that is, does not support the inter RAT arrangement.

Option 3: A field indicating a resource location arranged by the inter RAT;

The field indicates the resource location of another RAT arranged by the inter RAT, for example, the base station of the NR indicates the location of the LTE V2X resource (eg, arrangement by the resource pool, etc.), if the field exists If so, it indicates that the inter-RAT arrangement is supported, and the specific supported distribution mode may specifically indicate or default that only the resource distribution mode selected by the terminal itself is supported, or the resource pool location related to the field has already been assigned. Therefore, if the field does not exist, it indicates that inter RAT arrangement is not supported, that is, it implicitly indicates that inter RAT arrangement is not supported.

Step 2: The terminal device selects a cell according to the broadcast information.
