Embodiment 1
[0037] The eNB broadcasts the coordinate range of each relevant area in the cell, the corresponding V-RNTI (Vehicle Radio Network Temporary Identify, vehicle wireless network temporary identification), and / or area ID (Identify, identification) through the system broadcast message, thus, The V2X nodes in the cell will save the coordinate range of each relevant area, the corresponding V-RNTI and / or area ID. Wherein, the V-RNTI and / or area ID corresponding to each relevant area is unique within the cell, and the coordinate range of the relevant area can be indicated by the GPS (Global Position System, Global Positioning System) coordinates of the vertices of the relevant area. For example, if the shape of the relevant area is a rectangle, the coordinate range of the relevant area can be indicated by the coordinates of the four vertices of the rectangle, as in figure 1 As shown, the coordinate range of the relevant area 1 can be indicated by the coordinates of vertices A1, B1, C1 ...
Embodiment 2
[0055] In the second embodiment, one cell corresponds to one V-RNTI, that is, all related areas in the same cell correspond to the same V-RNTI. The value of the V-RNTI corresponding to a cell may be configured by the eNB or defined by a standard.
[0056] The V2X communication method in Embodiment 2 of the present application is as follows:
[0057] In the second embodiment, the steps to be performed by the sending V2X node are as follows figure 2 As shown, it is the same as the first embodiment.
[0058] The eNB determines the target location information according to the location information of the sending V2X node carried in the received V2X data information, carries the target location information in the corresponding downlink control channel, and uses the V-RNTI of the cell to scramble the corresponding downlink The CRC code of the control channel, the corresponding downlink control channel is used to indicate the downlink data channel carrying the V2X data information....
Embodiment 3
[0074] In the third embodiment, the receiving V2X node reports the location coordinates of the node to the eNB periodically or in an event-triggered manner, and receives the corresponding V-RNTI configured by the eNB. The receiving V2X node further detects the downlink control channel whose CRC code is scrambled by the V-RNTI corresponding to the node, and receives the V2X data information in the corresponding downlink data channel according to the indication of the detected downlink control channel.
[0075] The V2X communication method in the third embodiment is as follows:
[0076] The steps to be performed to send a V2X node are as follows: figure 2 As shown, it is the same as the first embodiment.
[0077] According to the location coordinates of the sending V2X node carried in the received V2X data information and the location coordinates reported by each receiving V2X node, the eNB determines the receiving V2X node that needs to receive the V2X data information, and u...
