Abstract

The invention provides a method for determining message broadcast time slots and a device. The method comprises steps of obtaining geological position information of a first terminal; obtaining an S-Disjunct code word corresponding to the first terminal according to the geological position information; and determining the time slot of the first terminal broadcast information according to the S-Disjunct code word. In this way, the problem of improper distribution of time slot resources can be effectively solved and message transmission efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of Internet of Vehicles communication, in particular to a method and device for determining a message broadcast time slot. Background technique [0002] A time slot is the smallest unit of circuit switched summary information transfer. Time division multiplexing is to transmit different signals in different periods of the same physical connection, and can also achieve the purpose of multiplex transmission. Time division multiplexing uses time as the parameter of signal division, so it is necessary to make the signals of different channels not overlap each other on the time axis. Time division multiplexing is to divide the time provided for the entire channel to transmit information into several time slices (referred to as time slots), and allocate these time slots to each signal source for use. [0003] Currently, message broadcast protocols can be divided into contention-based broadcast protocols and sche...
