Claim of US Patent No. 10,368,356

1. A vehicle-to-vehicle (V2V)-based resource allocation method comprising:receiving, by a base station, a resource request message sent by a first user equipment;
identifying, by the base station and according to the resource request message, a level type associated with the first user equipment;
allocating, by the base station, a V2V resource to the first user equipment from V2V resources occupied by a second user equipment in a first resource pool or from a second resource pool associated with another type other than a high priority type when the base station identifies that the level type associated with the first user equipment is the high priority type, and one of the following situations occur:
(a) a quantity of blocks of idle V2V resources having a same size in the first resource pool is less than a first preset threshold, and
(b) a quantity of required resource blocks is determined by the base station, according to an amount of data to be sent by the first user equipment and a modulation and coding scheme, to be greater than a quantity of blocks of idle V2V resources in a first resource pool,
wherein the V2V resource is used by the first user equipment to transmit V2V data, the first resource pool is a resource pool associated with the high priority type, and the second user equipment is of the another type;
allocating, by the base station, the V2V resource to the first user equipment from the second resource pool when the V2V resource allocated to the first user equipment is from the second resource pool, and when one of the following situations occur:
(a) a quantity of blocks of idle V2V resources having a same size in the second resource pool is not less than a second preset threshold, and
(b) the quantity of the required resource blocks obtained by the base station, according to the amount of the data to be sent by the first user equipment and the modulation and coding scheme, is not greater than the quantity of blocks of idle V2V resources in the second resource pool,
allocating, by the base station, the V2V resource to the first user equipment from the first resource pool when one of the following situations occur:
(a) the quantity of the blocks of the idle V2V resources having a same size in the first resource pool is not less than the first preset threshold, and
(b) the quantity of the required resource blocks obtained by the base station, according to the amount of the data to be sent by the first user equipment and the modulation and coding scheme, is not greater than the quantity of the blocks of the idle V2V resources in the first resource pool, and
sending, by the base station, a third indication message to the first user equipment, wherein the third indication message is used to instruct the first user equipment to release the occupied V2V resource in the second resource pool.
