Description
Technical Field
The invention relates to the technical field of communication, in particular to a method for indicating V2X network resource information and a base station.
Background
Vehicle to X (V2X) information exchange is a key technology of future intelligent transportation systems. V2X mainly studies a vehicle data transmission scheme based on a third Generation Partnership Project (3 GPP) communication protocol. The V2X applications currently in the existing report include: Vehicle-to-Vehicle (V2V), Vehicle-to-Infrastructure (V2I), Vehicle-to-Pedestrian (V2P), and Vehicle-to-Network (V2N). The application of V2X will improve driving safety, reduce congestion and vehicle energy consumption, improve traffic efficiency and vehicle-mounted entertainment information, etc.
At present, there are two Resource allocation manners for V2X, one is an evolved Node B (eNB) scheduling manner, and the other is a User Equipment (UE) autonomous Resource selection manner, where the base station scheduling manner is similar to a scheduling manner of a Device to Device (D2D) direct communication technology, and requires a UE to enter a Radio Resource Control (RRC) connection state to transmit data, the UE supporting a V2X function requests the eNB for resources used for transmitting data, and the eNB schedules resources used on a V2X secondary link (sildelink, S L).
The mode3 corresponding to the base station scheduling mode indicates that the base station configures a resource pool used by the UE, and then the base station allocates specific resource location Information in the configured resource pool to the UE through the PDCCH according to the Sidelink BSR reported by the UE, for example, the location Information of the resource used by the PC5 port (communication interface between UEs) of the UE for transmitting data is indicated through Downlink Control Information (DCI).
For the resource allocation mode of V2X being the mode3 mode corresponding to the scheduling mode, fig. 1 shows a scenario that a mode3 mode UE transmits a V2X service under the same carrier, and UE1 and UE2 transmit a V2X message in the mode3 mode, and resources used by them are allocated by eNB1, so that interference does not occur between UE1 and UE 2.
The current 3GPP protocol does not give a solution to the interference generated for the above scenario. For this reason, how to reduce interference by mode3 mode resource allocation among co-channel carriers becomes a problem to be solved.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some embodiments, but not all embodiments, of the present invention.
As shown in fig. 1, the method for indicating network resource information of V2X disclosed in this embodiment may include the following steps 201 and 202:
201. the source base station judges whether the resources used by the mode3 corresponding to the scheduling mode change; if yes, go to step 202; otherwise, no action is taken.
202. The source base station sends a message carrying V2X Sidelink resource information to each target base station connected with the source base station through an X2 port, so that each target base station allocates resources to edge users in a mode3 mode based on the V2X Sidelink resource information, and interference coordination of V2X Sidelink communication is achieved.
In this embodiment, each target base station considers that the current V2X Sidelink resource information is valid before receiving a new message carrying V2X Sidelink resource information.
It can be seen that, in the method for indicating V2X network resources provided in this embodiment, a source base station indicates, through an X2 port (a communication interface between base stations), V2X Sidelink resource information of the source base station to each base station connected to the source base station, so that when each base station connected to the source base station allocates V2X Sidelink resources to edge users in a mode3 mode, the V2X Sidelink resources of the source base station are considered, and the V2X Sidelink resources allocated to the edge users avoid the V2X Sidelink resources indicated by the source base station as much as possible, thereby effectively reducing the probability that the same resources are allocated to the source base station and the edge users of each base station connected to the source base station, effectively reducing secondary link interference in a cell edge area between cells of the same frequency, and improving cell edge user performance.
In a specific example, the determining, by the source base station in step 201, whether the resource used by the mode3 corresponding to the scheduling mode changes may include the following two points:
1. and the source base station judges whether the V2X resource pool corresponding to the scheduling mode changes.
In this embodiment, the source base station determines whether the V2X resource pool corresponding to the scheduling manner needs to be adjusted based on the load information; if it is determined that adjustment is necessary, it is described that the resource used in the mode3 corresponding to the scheduling method is changed.
2. And the source base station judges whether the periodic time-frequency resource of V2X Sidelink semi-persistent scheduling changes.
In this embodiment, a source base station determines whether to allocate a periodic time-frequency resource to a periodic V2X service initiated by a user equipment UE in a V2X Sidelink semi-persistent scheduling manner based on a preset policy based on whether the periodic V2X service initiated by the UE is received, and determines whether the periodic time-frequency resource for V2X Sidelink semi-persistent scheduling varies; if a periodic service initiated by User Equipment (UE) is received and the source base station determines to adopt a V2X Sildelink semi-persistent scheduling mode to allocate a periodic time-frequency resource to the periodic V2X service initiated by the UE based on a preset strategy, the resource used by a mode3 mode corresponding to the scheduling mode changes. The preset policy may follow the policy in the prior art, and the embodiment is not described in detail.
In this embodiment, the load information includes: the number of user equipments served by the base station (abbreviated as user volume) and traffic peak information, wherein the traffic peak information can be determined based on historical traffic records.
In this embodiment, the base station plans a V2X resource pool in advance for the mode3 corresponding to the scheduling mode, but as the load changes, for example, the user volume increases or the current traffic peak value is, the base station needs to increase the V2X resource pool, and the specific adjustment amount may be executed based on a preset adjustment strategy, which is not described in this embodiment; for another example, if the user amount is reduced or the current traffic peak is not, the base station needs to reduce the V2X resource pool, and the specific adjustment amount may be performed based on a preset adjustment policy, which is not described in this embodiment again.
In a specific example, the step 202 of the source base station sending, through an X2 port, a message carrying information of Sidelink resources of V2X Sidelink to each target base station connected to the source base station includes:
if the source base station determines that a V2X resource pool corresponding to a scheduling mode needs to be adjusted based on load information, and/or the source base station receives a periodic V2X service initiated by User Equipment (UE), and the source base station determines to adopt a V2X Sidelink semi-persistent scheduling mode to allocate periodic time-frequency resources to the periodic V2X service initiated by the UE based on a preset strategy, the source base station sends a message carrying V2X Sidelink resource information to each target base station connected with the source base station through an X2 port;
wherein the V2X Sidelink resource information includes: and V2X resource pool information corresponding to the scheduling mode and/or periodic time frequency resource information of V2XSidelink semi-persistent scheduling.
It can be seen that, in this embodiment, the source base station notifies, to each base station connected to the source base station, the V2X resource pool information corresponding to the scheduling mode and the periodic time-frequency resource information of V2X Sidelink semi-persistent scheduling, so that each base station connected to the source base station considers the scheduling policy of the V2X Sidelink resource in the mode3 mode under the same frequency carrier according to the resource information (including the V2X resource pool information corresponding to the scheduling mode and the periodic time-frequency resource information of V2XSidelink semi-persistent scheduling) used by the source base station in the mode3 mode, thereby effectively reducing the same frequency interference generated when the UE under different enbs use the mode3 mode to perform V2X Sidelink communication.
In a specific example, in step 202, the source base station sends a message carrying the Sidelink information of the V2X Sidelink to each target base station connected to the source base station through an X2 interface, which includes the following two ways:
the first method is as follows: and the source base station sends the V2X Silelink resource indication message carrying the V2X Silelink resource information to each target base station connected with the source base station through an X2 port.
In this manner, the V2X Sidelink resource indication message is a message sent by the newly added X2 port in this embodiment, and the V2X Sidelink resource indication message includes a V2X Sidelink resource Information cell (V2X Sidelink resource Information Element), where the cell carries the V2X Sidelink resource Information.
The second method comprises the following steps: and the source base station sends the load information message carrying the V2X Sildelink resource information to each target base station connected with the source base station through an X2 port.
In this manner, the load INFORMATION (L OAD INFORMATION) message is a message sent by the original X2 port, and in this embodiment, a V2X Sidelink Resource INFORMATION cell (V2X Sidelink Resource INFORMATION Element) is added to the load INFORMATION message, where the V2X Sidelink Resource INFORMATION is carried in the cell.
It can be seen that, in this embodiment, a new V2X Sidelink Resource INFORMATION cell (V2XSidelink Resource INFORMATION Element) is added to an X2 port message (V2X Sidelink Resource indication message) or an original load INFORMATION (L OAD INFORMATION) message of an X2 port, and is used to carry V2X Sidelink Resource INFORMATION of a source base station.
In a specific example, the V2X Sidelink resource information in the above embodiment includes: the source cell identification and the target cell identification further comprise: V2X resource pool information corresponding to the scheduling mode and/or periodic time frequency resource information of V2X Sidelink semi-persistent scheduling;

the source cell is a cell corresponding to the source base station, and the target cell is a cell corresponding to the target base station.
In this embodiment, the V2X Sidelink semi-persistent scheduling periodic time-frequency resource information may further include a number of usage times of the periodic time-frequency resource, where the number of usage times of the periodic time-frequency resource is selectable.
In this embodiment, for the V2X Sidelink semi-persistent scheduling periodic time-frequency resource information, if the current time of the source base station has the periodic time-frequency resource allocated for the UE by the semi-persistent scheduling, the V2X Sidelink resource information includes the V2X Sidelink semi-persistent scheduling periodic time-frequency resource information, otherwise, the information is not carried.
In this embodiment, when the base station uses the cross-carrier scheduling manner, the V2X Sidelink resource indication message and the V2X Sidelink resource information cell of the load information message in the above embodiment may also carry V2X communication frequency point information and V2X Sidelink bandwidth information.
