The process of selecting a target cell among neighboring cells to provide a service signal for the terminal, where the target cell is a neighboring cell that can provide a service signal with the highest signal quality for the terminal.

Currently, the resource pool configuration of the terminal can be regionally effective or non-regional effective. Regionally effective means that the resource pool may be effective in the serving cell and other non-serving cells, and non-regional effective means that the resource pool is only effective in the serving cell.

The following describes the concepts involved in the embodiments of the present application.

1. Residential reselection

Cell reselection can be divided into intra-frequency (intra-frequency) cell reselection, inter-frequency (inter-frequency) cell reselection, and inter-RAT (inter-RAT) cell reselection. In intra-frequency cell reselection, the terminal selects the cell that meets the same frequency reselection criterion on the current serving frequency to perform cell reselection. Inter-frequency cell reselection means that the terminal selects cells corresponding to the R criterion of the RAT on other frequencies configured by the RAT for reselection. The inter-RAT cell reselection is that the terminal selects the cell corresponding to the R criterion of the inter-RAT on the frequency point configured by the other RAT for reselection.

2. V2X communication

V2X communication refers to the general term for communication methods such as vehicles obtaining road condition information or receiving information services. V2X communication includes: V2V, V2I, V2P, V2N and other communication methods. For V2I communication, roadside infrastructure, such as RSU, can provide vehicles with various service information and data network access, and functions such as non-stop toll collection and in-car entertainment have greatly improved the intelligence of traffic.

3. NR V2X communication system

The NR system is currently the mainstream wireless communication technology. It is starting to formulate related standards for the characteristics of V2X services and new service transmission requirements. The goal is to support V2X communication with lower latency and higher reliability. Its application scenarios include autonomous driving. (automated driving). Specifically, in the NR V2X system, there are two types of air interfaces, Uu and PC5. Uu port: used for communication between terminal and base station; PC5 port: used for SL communication between terminal and terminal.

For the PC5 port, two resource allocation modes are supported: Mode1 and Mode2. Mode1 mode is used for dedicated resource allocation. Network equipment can allocate resources through the dedicated RNTI of the terminal equipment, mainly supporting connected terminals. Mode2 mode is used for the allocation of competing resources. The competing resources are configured by system message broadcast or dedicated signaling. For terminals in IDLE, inactive, and connected states, the competing resources are shared and used by more than one terminal.

The resources in this application are not limited to mode 1, which is applicable to the resource allocation method of base station scheduling in subsequent evolution; nor is it limited to the use of mode 2, which is applicable to the UE autonomous resource allocation method in subsequent evolution.

It should be understood that the NR mode 1 in the present invention can be extended to the resource allocation mode scheduled by the base station in the future evolved V2X SL communication. In other words, the NR mode 1 in this application can be replaced with the resource allocation mode scheduled by the base station in the future evolution of V2X SL communication. The NR mode 2 in the present invention can be extended to the UE autonomous resource allocation method in the future evolved V2X SL communication. In other words, the NR mode 2 in the application can be replaced with the UE autonomous resource allocation method in the future evolved V2X SL communication.

In order to facilitate the understanding of the information transmission method in the embodiments of the present application, it will be described in detail below in conjunction with specific embodiments.

Example one

Fig. 2 is a schematic diagram of an embodiment of an information transmission method provided in an embodiment of the application.

As shown in Figure 2, the information transmission method in the embodiment of the present application includes:

201. The network device broadcasts the first information in the system information.

The serving cell is the cell where the terminal resides. The first information is used to indicate whether the resource pool is valid in the neighboring cell of the serving cell.

The first information may include but is not limited to: at least one of an area identification ID, a resource pool version identification, and a public land mobile network identification PLMN-Identity. The area ID indicates the effective area corresponding to the resource pool where the area is valid. For example, the area ID indicates that the resource pool is valid in the cells 1-10. The resource pool version identifier indicates the version corresponding to the effective resource pool in the region.

In the scenario of V2X SL service transmission on the Internet of Vehicles side link, the effective regional resource pool can be the regional effective V2X SL resource pool, or in other words, the regional effective resource pool can be the resource pool corresponding to the V2X SL configuration as the regional effective resource pool . The resource pool version identifier can be the value Tag of the effective V2X SL resource pool in the area.

202. The terminal obtains the first information in the system information broadcast by the network device.

If the resource pool currently used by the terminal is regionally effective, or in other words, the terminal currently uses a regionally effective resource pool, the terminal obtains the first information in the system information broadcast by the network device.

Of course, if the resource pool currently used by the terminal is non-regional effective, or in other words, the terminal currently uses a non-regional effective resource pool, the terminal will not obtain the aforementioned first information.

The terminal can judge in the serving cell whether the currently used resource pool is valid in the neighboring cells of the serving cell. Specifically, the terminal can obtain the first information from the system information of the serving cell and/or the system information SI of the neighboring cell of the serving cell, so as to determine whether the resource pool it currently uses is valid in the neighboring cell of the serving cell. . Specifically, the manner in which the network device broadcasts the first information is different, and the manner in which the terminal obtains the first information is also different. The terminal can obtain the first information in but not limited to the following ways.

1. The network device broadcasts the first information in one or more system information blocks SIBs of the serving cell

The terminal obtains the SIB n of the serving cell and/or the first information in the SIB m, where n and m are integers greater than or equal to 1, and m and n are not equal.

Exemplarily, in the scenario of V2X SL service transmission on the Internet of Vehicles side link, the terminal reads the effective V2X SL resource pool of the same-frequency neighboring cells and inter-frequency neighboring cells carried in the SIB3 and/or SIB4 of the serving cell At least one of the area ID, value Tag, and PLMN-Identity.

2. The network device broadcasts the first information in the SIB of the neighboring cell of the serving cell and the SIB of the serving cell

The terminal obtains the SIB1 of the neighboring cell of the serving cell, and the first information in the SIB n and/or SIB m of the serving cell, where n and m are integers greater than or equal to 1, and m and n are not equal.

Exemplarily, in the scenario of V2X SL service transmission on the side link of the Internet of Vehicles. The area ID is broadcast in the SIB 1 of the neighboring cell of the serving cell, and only at least one of the value Tag and the PLMN-Identity needs to be broadcast in the SIB3 and/or SIB4 of the serving cell. The terminal obtains the area ID of the effective V2X SL resource pool of the serving cell from the SIB1 of the neighboring cell of the serving cell, and obtains the value Tag of the effective V2X SL resource pool of the serving cell and the value Tag in the PLMN-Identity from the SIB3 and/or SIB4 of the serving cell. At least one.

3. The network device broadcasts the first information in an SIB of a neighboring cell of the serving cell.

The terminal obtains the first information broadcast in the system information block n of the neighboring cell of the serving cell, where n is an integer greater than or equal to 1.

Exemplarily, in the scenario of V2X SL service transmission on the side link of the Internet of Vehicles. On the one hand, the terminal reads at least one of the area ID, value Tag, and PLMN-Identity of the area valid V2X SL resource pool broadcasted in the IoV specific system information block V2X specific SIB of the neighboring cell of the serving cell.

On the other hand, the end reads at least one of the area ID, value Tag, and PLMN-Identity of the area valid V2X SL resource pool broadcast in the SIB1 of the neighboring cell of the serving cell.

4. The network device broadcasts the first information in SIB1 and other SIBs of neighboring cells of the serving cell.

The terminal obtains the system information block 1 of the neighboring cell of the serving cell, and/or the first information broadcast in the system information block n, where n is an integer greater than or equal to 2.

Exemplarily, in the scenario of V2X SL service transmission on the side link of the Internet of Vehicles. The terminal reads the area ID of the effective V2X SL resource pool in the system information block 1 of the neighboring cell of the serving cell, and reads the value Tag and PLMN-Identity of the effective V2X SL resource pool in the system information block 3 or 4. At least one of.

Optionally, 203. If the resource pool currently used by the terminal is regionally valid, the terminal determines, according to the acquired first information, that the resource pool configuration currently used by the terminal is valid in a neighboring cell of the serving cell.

The terminal can determine that the resource pool configuration currently used by the terminal is valid in the neighboring cell of the serving cell in the following manner. The second information in the following manner is used to indicate the effective information of the resource pool area currently used by the terminal.

The first way:

If the second information is the same as the first information, the terminal determines that the resource pool configuration currently used by the terminal is valid in the neighboring cell of the serving cell. The first information includes: area ID, resource pool version identifier and public land mobile network identifier. Indicate one item.

The above-mentioned second information may correspond to the serving cell, or may correspond to the effective resource pool in the serving cell. Similarly, the first information may correspond to the neighboring cell of the serving cell, or may correspond to the effective resource pool in the neighboring cell of the serving cell.

The first method may be applicable to a scenario where the first information obtained by the terminal includes an area ID.

On the one hand, in the case that the second information corresponds to the effective resource pool of the area in the serving cell, if the area ID corresponding to the resource pool currently used by the terminal is the same as the area ID indicated by the first information, the terminal determines the resource pool currently used by the terminal The configuration is valid in the neighboring cells of the serving cell. The area ID indicated by the above first information may correspond to the neighboring cell of the serving cell, or may correspond to the effective resource pool in the neighboring cell of the serving cell.

On the other hand, in the case that the second information corresponds to the serving cell, if the area ID corresponding to the serving cell is the same as the area ID indicated by the first information, the terminal determines that the resource pool currently used by the terminal is configured in the neighboring cell of the serving cell effective. Similarly, the area ID indicated by the aforementioned first information may correspond to the neighboring cell of the serving cell, or may correspond to the effective resource pool in the neighboring cell of the serving cell.

In the two aspects corresponding to the above-mentioned first method, if the first information also includes the resource pool version identifier and/or the public land mobile network identifier, the terminal will also compare the resource pool version identifier and/or the resource pool version identifier while comparing the area ID. Or the public land mobile network identity is compared, and only when the area ID, resource pool version identity and/or public land mobile network identity are the same, the terminal determines that the resource pool configuration currently used by the terminal is valid in the neighboring cell of the serving cell.

The second way:

If the cell identity list corresponding to the resource pool currently used by the terminal includes the cell identity of the neighboring cell of the serving cell, and/or the first information is the same as the second information, the terminal determines that the resource pool currently used by the terminal is configured in the serving cell Effective in neighboring cells.

The second method can be applied to a scenario where the area ID is not included in the first information obtained by the terminal.

Specifically, in the case where the second information corresponds to the serving cell:

1. If the cell identifier list corresponding to the resource pool currently used by the terminal includes the cell identifier of the neighboring cell of the serving cell, the terminal determines that the resource pool configuration currently used by the terminal is valid in the neighboring cell of the serving cell.

2. If the cell identifier list corresponding to the resource pool currently used by the terminal includes the cell identifiers of the neighboring cells of the serving cell, and, the resource pool version identifier in the first information corresponds to the resource pool version identifier corresponding to the resource pool currently used by the terminal Similarly, the terminal determines that the resource pool configuration currently used by the terminal is valid in the neighboring cell of the serving cell.

3. If the cell identity list corresponding to the resource pool currently used by the terminal includes the cell identity of the neighboring cell of the serving cell, and, the public land mobile network identity in the first information corresponds to the public land mobile corresponding to the resource pool currently used by the terminal The network identifier is the same, and the resource pool version identifier in the first information is the same as the resource pool version identifier corresponding to the resource pool currently used by the terminal, and the terminal determines that the resource pool configuration currently used by the terminal is valid in a neighboring cell of the serving cell.

Similarly, in the case where the second information corresponds to the effective resource pool in the serving cell, a similar manner can also be used to determine that the resource pool configuration currently used by the terminal is effective in the neighboring cell of the serving cell.

In the above two cases of the second method, the resource pool version identifier and the public land mobile network identifier indicated by the first information may both correspond to the neighboring cells of the serving cell, or may be neighbors of the serving cell. Corresponding to the effective resource pool in the cell area.

In the first embodiment, when the resource pool currently used by the terminal is effective in the area, the information of the effective resource pool in the neighboring cell of the serving cell is obtained, and it is determined that the resource pool currently used by the terminal is configured in its cell. An effective cell allows the terminal to reselect as much as possible to a cell with a valid resource pool configuration, so that the terminal can sense under the same resource pool configuration after reselection, and its delay is longer than that under the handover resource pool configuration. The delay is small, thereby reducing the delay caused by the sensing resource pool after reselection, and reducing the probability of service transmission interruption during the cell reselection process.

The embodiment of the application provides a method for determining the reselection cell, which is used to improve the existing cell reselection process, so that the terminal can reuse the original used in the serving cell after reselecting to the reselection cell Resource pool configuration avoids the time delay caused by re-perceiving the resource pool after reselection, and reduces the probability of service terminals.

The following describes in detail the method for determining the reselected cell in the embodiment of the present application in combination with the second embodiment and the third embodiment.

Example two

Fig. 3 is a schematic diagram of an embodiment of a method for determining a reselected cell provided in an embodiment of the application.

301. If the resource pool currently used by the terminal is valid in the area, and the resource pool currently used by the terminal is valid in the candidate cell, the terminal selects the candidate cell with the largest R value and the current resource pool configuration used by the terminal is the first effective candidate cell. Community.

The candidate cell is a cell that meets the cell reselection condition among the neighboring cells of the serving cell. Specifically, the candidate cells may include: same-frequency cells that meet the same-frequency cell reselection criterion among neighboring cells of the serving cell, or those that meet the same priority inter-frequency cell reselection criterion among neighboring cells of the serving cell Inter-frequency cells of equal priority, or inter-frequency cells of unequal priority that meet the reselection criteria for inter-frequency cells of unequal priority among neighboring cells of the serving cell.

For example, under the condition that the duration of the terminal staying in the current serving cell is not less than a predetermined duration (such as 1 second), the terminal determines one or more cells whose R value is higher than the R value of the serving cell within a continuous time as candidate cells through the R criterion. .

The above R value is determined according to the R criterion. For the R criterion, please refer to the related description in the existing cell reselection process, which will not be repeated this time.

Optionally, before step 301, the terminal may also perform a method similar to the above step 203 to determine that the resource pool currently used by the terminal is valid in the candidate cell, which will not be repeated here.

Optionally, under the condition of determining the priority of the frequency point, the terminal executes the foregoing step 301. The frequency point priority determination method can be combined with the technical solutions described in the fourth and/or fifth embodiment below.

302. The terminal performs a check operation on the first cell to obtain a first check result.

The verification operation may be bar verification, and the corresponding first verification structure includes: access prohibited or non-barred access.

303. If the first check result is that access is not barred, the terminal determines that the first cell is a reselected cell.

The reselection cell refers to the cell that the terminal will reselect.

304. If the first check result is that access is prohibited, the terminal removes the first cell from the candidate cell.

Specifically, the terminal may remove the first cell from the candidate cell, so that the terminal permanently does not consider the first cell as a candidate cell. The terminal may also remove the first cell from the candidate cells within a preset time period (such as 300 seconds), so that the terminal does not consider the first cell as a candidate cell within the preset time period; after the preset time period is exceeded, the terminal will select the first cell again. One cell serves as a candidate cell.

Exemplarily, if the first check result is that access is prohibited, the terminal selects the cell with the largest R value among the updated candidate cells and the current use of the resource pool configured by the terminal to be valid in the candidate cell, and performs bar verification. The result is that access is not forbidden. The terminal determines the cell with the largest R value in the current candidate cell and the current resource pool configuration of the terminal that is valid in the candidate cell as the reselected cell; if the bar check result is that access is prohibited, the terminal first Among the candidate cells, the cell with the largest R value and the terminal’s current resource pool configuration valid in the candidate cell is deleted from the candidate cells, and then the updated candidate cell with the largest R value and the terminal’s current resource pool configuration valid in the candidate cell is selected. The cell continues to perform bar verification.

305. If the resource pool currently used by the terminal in the candidate cell is configured in the candidate cell and the check results corresponding to the N cells that are valid in the candidate cell are all barred from access, the terminal determines that the cell with the largest R value in the candidate cell and which is not barred from access is a heavy Select cells, where the N cells are some or all of the candidate cells.

Among the candidate cells, the cell with the largest R value and bar check as non-barred access has nothing to do with whether the resource pool configuration currently used by the terminal is valid in its cell. Specifically, among the candidate cells, the cell with the largest R value and bar check as non-barred to access can be a cell in which the resource pool currently used by the terminal is configured to be effective in its cell, or the resource pool currently used by the terminal is configured in its cell. Invalid cell in the cell.

In the second embodiment, the terminal first determines the resource pool currently used by the terminal in the candidate cell to configure the effective cell in its cell, and then performs bar check according to the R value, so that the terminal selects the candidate cell currently used by the terminal as much as possible The effective cell of the resource pool configuration in its cell is used as the reselected cell, so that after reselection, the terminal can sense under the same resource pool configuration, and its delay is smaller than that of sensing under the handover resource pool configuration, thereby reducing After reselection, the additional delay caused by the new resource pool is sensed, and the probability of service transmission interruption during the cell reselection process is reduced.

Example three

Fig. 4 is a schematic diagram of an embodiment of another method for determining a reselected cell provided in an embodiment of the application.

401. If the terminal currently uses the first resource pool with a valid area, the terminal selects the second cell with the largest R value among the candidate cells.

The candidate cell is a cell that meets the cell reselection condition among the neighboring cells of the serving cell. Specifically, the candidate cells may include: same-frequency cells that meet the same-frequency cell reselection criterion among neighboring cells of the serving cell, or those that meet the same priority inter-frequency cell reselection criterion among neighboring cells of the serving cell Inter-frequency cells of equal priority, or inter-frequency cells of unequal priority that meet the reselection criteria for inter-frequency cells of unequal priority among neighboring cells of the serving cell.

For example, under the condition that the duration of the terminal staying in the current serving cell is not less than a predetermined duration (such as 1 second), the terminal determines one or more cells whose R value is higher than the R value of the serving cell within a continuous time as candidate cells through the R criterion. .

The above R value is determined according to the R criterion. For the R criterion, please refer to the related description in the existing cell reselection process, which will not be repeated this time.

Optionally, under the condition of determining the frequency point priority, the terminal executes the foregoing step 401. The frequency point priority determination method can be combined with the technical solutions described in the fourth and/or fifth embodiment below.

402. The terminal performs a check operation on the second cell to obtain a second check result.

The verification operation may be bar verification, and the corresponding second verification structure includes: access prohibited or non-barred access.

403. If the second check result is that access is not forbidden, and the resource pool configuration currently used by the terminal is valid in the second cell, the terminal determines that the second cell is a reselected cell.

The reselection cell refers to the cell that the terminal will reselect. Optionally, under the condition that the second check result is that access is not forbidden, the terminal can perform operations similar to those in 203 above to determine that the resource pool configuration currently used by the terminal is valid in the second cell, which will not be repeated here. .

404. If the second check result is that access is prohibited, the terminal removes the second cell from the candidate cell.

Specifically, the terminal may remove the second cell from the candidate cell, so that the terminal permanently does not consider the second cell as a candidate cell. The terminal can also remove the second cell from the candidate cell within a preset time period (for example, 300 seconds), so that the terminal does not consider the second cell as a candidate cell within the preset time period; after the preset time period, the terminal will select the second cell again. The second cell is a candidate cell.

Exemplarily, if the second check result is that access is prohibited, the terminal selects the cell with the second largest R value among the candidate cells to perform bar check.

Specifically, when the terminal has V2X services being transmitted or interested V2X services to be transmitted, that is, the terminal is configured for V2X service communication, the terminal uses the second priority; otherwise, when the terminal has no V2X services being transmitted or interested If the V2X service is waiting to be transmitted, that is, when the terminal is not configured for V2X service communication, the terminal uses the first priority.

In the fourth embodiment, by adding a second priority that considers both the Uu port and the side link, the current V2X traffic load (V2X resource occupancy) of the cell/frequency is used as one of the set frequency priorities. This kind of reference, so as to avoid the overload of the reselected new cell or the difficulty of V2X communication after the terminal reselects to the cell.
