Embodiment Construction

[0095] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure clearer, the embodiments of the present disclosure will be further described in detail below in conjunction with the accompanying drawings.

[0096] According to the solution in the background art, if two UEs are synchronized based on the downlink synchronization signal sent by the base station, the requirement of the UE in the Internet of Vehicles system to synchronize data signals transmitted by other UEs cannot be met. The following takes the carrier frequency of 64GHz (a potential frequency band that may be selected by the Internet of Vehicles) as an example for illustration.

[0097] In order to support higher frequency bands and larger bandwidths than LTE, 5G NR technology has designed a variety of optional combinations of subcarrier spacing (subcarrier spacing, SCS) and CP length, see Table 1, Table 1 shows some current Supported SCS and CP length combina...

Abstract

The disclosure provides a synchronization method and device, which belong to the technical field of communications. The method includes: determining a data signal, the target sequence in the data signal is mapped on at least one symbol including the first symbol in a time unit, and the data in the data signal is mapped on the symbols other than the at least one symbol in the time unit On the other at least one symbol, the first symbol includes a cyclic prefix, and the target sequence is used by the second device to synchronize the data signal; and the data signal is sent to the second device at the time unit. In the present disclosure, at least one symbol including the first symbol in the time unit of each transmission maps the sequence used to synchronize the data signal of this transmission at equal intervals, so that the device receiving the data signal can The sequence and the sequence known to be used for synchronization are used to synchronize data signals, which meets the requirements of devices in the Internet of Vehicles system to synchronize data signals transmitted by other devices.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular to a synchronization method and device. Background technique [0002] The Internet of Vehicles system realizes information sharing through communication between vehicles, vehicles and transportation facilities, and vehicles and pedestrians. In order to ensure the safe driving of vehicles, data interaction between user equipment (UE) in the Internet of Vehicles system is required, such as periodically sending information such as its own position, speed, and status to surrounding UEs. 5G network (new radio, NR) technology is the next-generation mainstream wireless communication technology. Currently, the industry is researching 5G-based Internet of Vehicles technology to provide reliable data transmission and interaction for each UE in the Internet of Vehicles system. During data interaction, in order to ensure that the data can be received correctly, the receivin...
