Abstract

An embodiment of the disclosure provides a method and apparatus for reducing the delay in vehicle-to-vehicle communication. The method comprises the steps of allocating separate scheduling allocation resource pools for messages with different delay requirements; and performing frequency division multiplexing of a scheduling allocation resource pool for a first message requiring a lower delay and a corresponding data resource pool, to reduce the transmission delay of the first message. Compared with the prior art, the embodiment of the disclosure are effective in reducing the transmission delay of the emergency message, thus satisfying the delay requirements for vehicle safety message communication.

Description

technical field [0001] Embodiments of the present disclosure generally relate to the field of wireless communication, and in particular to a method and device for reducing delay in vehicle-to-vehicle communication. Background technique [0002] Latency requirements are very stringent for the communication of vehicle safety messages. For example, for periodic vehicle safety messages, most latency requirements are in the range of 100 ms or more. In vehicle-to-vehicle (i.e. V2V) communication, the most stringent latency requirement is 20ms for pre-collision warning situations. [0003] Device-to-device (D2D) direct communication specified in Release 12 (R12) of Long Term Evolution (LTE) of the 3rd Generation Partnership Project (3GPP) cannot meet delay requirements of vehicle communication. Therefore, the field needs to enhance the D2D direct communication to meet the above-mentioned delay requirements for vehicle safety message communication. Contents of the invention [...
