Problems solved by technology

[0005] In the above process, when the distance between vehicles belonging to the same area is relatively short, it is likely to be allocated to overlapping time-frequency resources for the sidelink, resulting in conflicts between the time-frequency resources for the sidelink. Affects communication quality between vehicles

Abstract

The invention discloses a resource allocation method and device, which are used for solving the problem of transmission conflict of terminal device on a sidelink, and can be applied to communication systems such as device-to-device (D2D), Internet of Vehicles (V2X) or machine type communication (MTC) and the like. The method comprises: a first terminal device receiving notification messages sent by other terminal devices, and then the first terminal device needing to determine a first identifier different from an identifier in at least one notification message received within a first duration;sending a first notification message carrying the first identifier; and the first terminal device sending the first identifier to the network device. The network device can allocate time-frequency resources for the sidelink to the first terminal device according to the first identifier and identifiers reported by other terminal devices.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a resource allocation method and device. Background technique [0002] Vehicle to X (V2X) means that vehicles can communicate with external devices. Through V2X, communication can be realized between vehicles and vehicles, between vehicles and base stations, and between base stations, so that vehicles can better obtain various traffic information such as real-time road conditions, road information, and pedestrian information, thereby improving driving safety and improving traffic efficiency. . [0003] In V2X, in order to ensure that vehicles can communicate, it is necessary to allocate time-frequency resources for sidelinks to vehicles, so that vehicles can perform data transmission with other vehicles in the communication group on the allocated sidelink resources. [0004] At present, the time-frequency resource allocation method for the sidelink in V2X...
