Abstract: The present application discloses a resource allocation method, relates to the communications field, and resolves a problem that overall system performance is degraded because all vehicles use fixed four-time transmission when broadcasting service data packets to nearby vehicles. A specific solution is as follows: A receiving unit receives a transmission resource request sent by a first terminal device; a determining unit determines a quantity of transmission times in response to the transmission resource request received by the receiving unit; an allocation unit allocates a resource set to the first terminal device according to the quantity of transmission times determined by the determining unit, where a quantity of resources included in the resource set is equal to the quantity of transmission times; and a sending unit sends, to the first terminal device, time-frequency resource location information of each resource in the resource set allocated by the allocation unit.
