Claim of US Patent No. 10,462,784

1. A method for allocating a resource in a V2X system, the method comprising:allocating, by a network-side device, sub-frame resources for node devices initially accessing a cell, and notifying the initially allocated sub-frame resources to the node devices initially accessing the cell; and
determining, by the network-side device, colliding node devices among the node devices which have accessed the cell, reallocating sub-frame resources for the colliding node devices, and notifying the reallocated sub-frame resources respectively to the colliding node devices;
wherein determining, by the network-side device, the colliding node devices comprises:
determining, by the network-side device, the colliding node devices according to interference information related to a sub-frame resource with interference reported by the node devices which have accessed the cell; and/or
determining, by the network-side device, the colliding node devices according to current positional information, of the node devices which have accessed the cell, reported by the node devices;
wherein determining, by the network-side device, the colliding node devices according to the interference information reported by the node devices in the cell comprises:
determining, by the network-side device, the sub-frame resource with interference according to such information carried in the interference information that indicates a gap between the sub-frame resource with interference and a sub-frame in which the interference information is transmitted; and
determining, by the network-side device, such node devices in the cell that access the sub-frame resource with interference, according to the positional information of the node devices in the cell, and allocation information of the sub-frame resources of the node devices in the cell, and determining the determined node devices as the colliding node devices; and
the determining, by the network-side device, the colliding node devices according to the positional information reported by the node devices in the cell comprises:
updating by the network-side device, its stored distances between node devices multiplexing sub-frame resources, according to the positional information reported by the node devices in the cell, and the sub-frame resources allocated by the network-side device for the node devices in the cell; and
determining, by the network-side device, node devices multiplexing any one of sub-frame resources as the colliding node devices, upon determining that a distance between the node devices multiplexing the any one of sub-frame resources is shorter than a preset shortest distance at which the any one of sub-frame resources is multiplexed.
